Description

Technical area

The present invention relates to a well room for a groundwater well with the features of the preamble of claim 1.

State-of-the-art groundwater wells convey groundwater to the surface via a riser using an electric deep well pump.

The deep well pump is suspended in a well pipe that protrudes several meters into the groundwater from the top of the ground in the area of the aquifer. The upper end of the well pipe, in the GOK area, is closed with a well head (well cover) and leads the riser and the pump cable out of the pipe.

According to the current state of the art, two expansion options are common for a proper well closure, i.e. for the installation of the well head (also known as the well cover) on the well pipe in a well room.

The well closure in a well room underfloor (below ground level GOK) and above ground (above ground level ground level).

The underground well closure requires a water-tight and flood-proof well closure in a well shaft. As a rule, these are precast concrete shafts defined in accordance with the standard DIN 4034-2: 2013-05 and DIN 1239: 2018-04 that form a shaft at the top of the site, into which no surface water or rainwater can penetrate, in order to keep the well closure and thus the groundwater in the well free of contamination.
The well closure in a well room above the upper edge of the ground, i.e. a well closure in which the well pipe with the well head attached protrudes from the ground above ground level, finds the appropriate well closure in an installation house built above ground.

Both of these expansion options require, in addition to the costs, high material and construction costs for the well construction. Well shafts made of concrete are usually 600mm in diameter and, due to their dimensions and weight, require machines for installation. Installation houses set up above ground are also expensive.

The prior art is based on the following inventions which attempt to solve the disadvantages and problems explained above.

The disclosure document DE 203 01 736 U1 describes a well cover hood to be installed above ground, in the form of a hinged hood, mounted on a frame with a hinge. The advantage of this invention is intended to remedy the complex and disadvantageous underground well installation in which a well cover hood replaces a conventional well shaft. With this invention, the well closure is made above ground level. The disadvantage of this invention is that the frame of the well shaft must be dowelled onto a floor slab poured into concrete or screed, or due to the lack of a floor, screed is poured out. Another disadvantage here is that the shaft cannot be opened if the water is above ground level (surface water), otherwise surface water will flow into the well and flood the installation. Furthermore, concrete or screed, dowels and additional tools are required for the installation.

The disclosure document DE 7046227 also describes a well covering hood to be installed above ground, in the form of a hinged hood, on a foundation poured over the top of the terrain with a frame to be screwed on and has the same disadvantages.

The disclosure document AT 500 347 B8 describes a well sunk into the ground with a part of the cathedral that partially protrudes above the top of the ground. This well room is also not easy to use due to its dimensions.

The disclosure document DE000001993485U discloses an industrially prefabricated steel boiler with access for people, which serves as a well room with a pre-assembled well head. This invention is intended for large wells with well pipes made of steel, on which the well room with the well head is placed and welded. The well room also needs a concrete foundation. Their heavy weight makes transport and installation difficult.

In addition to the well closures presented, there are more and more smaller wells in private households which are used for irrigation of green areas or for the general extraction of groundwater as process water. These are known as garden fountains or irrigation fountains. They are usually built up to 50m deep and have a well pipe diameter of 3 "to 5".

These wells also deliver groundwater to the surface through a deep well pump, which is immersed in the well pipe and hung in the aquifer.

For such garden fountains, due to the high costs, none of the above-described well rooms are usually built and an improper well closure is accepted by the well builder and the client.

In practice, therefore, most of the well closures are found in the area above the top of the site and without a well.

The well pipe protrudes 30-50 cm from the ground above ground level in order to keep the well cover off the ground and to avoid possible contamination of the well groundwater by the ground or superficial water accumulation.

The well closure is thus only made up of a well pipe protruding from the ground with a well head attached and a pump pressure switch or pump control mounted on it and one or more water connections.

These well closures not only look unprofessional, but have the disadvantage that the well is freely accessible and the well pipe with pressure switch and water fittings can be damaged. In addition, not every commercially available pump pressure switch may be exposed to weather conditions. Rain and / or jets of water from irrigation systems pose a problem for many pressure switches and pump controls due to the low IP protection class. Solar radiation fades plastic and makes the plastic housing brittle for years.

In order to remedy these problems, it happens again and again that in garden fountains a well closure is made under the floor, in an irrigation box for solenoid valves that is not used or in an earth shaft as a well room for the well closure.

These irrigation boxes or earth shafts are not surface water-tight and have no bottom through which the well pipe with well head and pump control can be installed in a sealed manner against soil moisture or surface water penetrating through the well cover. In addition, there is condensation water that drips from the underside of the flat cover onto the electrical installation due to a lack of ventilation. Such an expansion has the consequence that the well room with the sensitive pump control / pump electrics is permanently exposed to moisture and irrigation water due to rain or garden irrigation can stand under water, as the seeping water through the missing shaft floor or an unsealed floor from below into the Well room can rise.

Furthermore, when connecting a groundwater well (operated by a deep well pump, which is controlled by a pressure switch and supplied with electricity) to a downstream irrigation system, the problem is that the irrigation control also requires an installation room protected from rain and direct sunlight. Cables must therefore be laid between the pump control, the irrigation control and a power source. Not only does this make the entire installation time-consuming, complicated and expensive, it also requires an electrician to lay the power cables.

• Eine Bewässerungssteuerung wird von einer Stromquelle mit Strom versorgt. Diese versorgt die Pumpensteuerung und die daran angeschlossene Tiefbrunnenpumpe mit Strom, sowie dem elektrischen Signal (Pumpe ein- / ausschalten). Die Tiefbrunnenpumpe fördert das Grundwasser aus dem Brunnen in das Bewässerungssystem. Welches in der Regel durch direkt von der Bewässerungssteuerung geschaltete Magnetventile, den Volumenstrom auf einzelne Bewässerungsleitungen verteilt.

Example of the function and electrical connection of a groundwater well in connection with an irrigation control system:

• An irrigation controller is powered by a power source. This supplies the pump control and the connected deep well pump with electricity as well as the electrical signal (switch the pump on / off). The deep well pump pumps the groundwater from the well into the irrigation system. Which, as a rule, distributes the volume flow to individual irrigation lines through solenoid valves switched directly by the irrigation control.

It is therefore the object of the present invention to create a well room (product) which allows a well to be installed and cost-effective in accordance with the rules of technology, through a compact, industrially prefabricated and ready-to-connect solution as a well room, in particular for private users and thus a Provides installation space for the well closure and the electrical control components that is protected against rising ground water, rain, moisture, condensation, solar radiation and other external influences.

It is also advantageous if the well room offers a weather-protected installation room for the irrigation control and thus enables a direct electrical connection to the pump control and the well pump so that there is no need to lay a power cable between the well and an externally installed irrigation control (e.g. in a garage or garden shed).

According to the invention, this object is achieved by a well with the features of claim 1.

• - einen eingrabbaren und wasserdichten Erdschacht, dadurch gekennzeichnet, dass eine im Schachtboden installierte Gummi-Lippendichtung zur wasserdichten Aufnahme des Brunnenrohrs in die Brunnenstube eingesetzt ist,
• - eine aufsetzbare und abschließbare Haube
• - wenigstens einer von der Tiefbrunnenpumpe über die Druckleitung gespeisten Tankdurchführung mit Zapfstelle, sowie
• - ein Gehäuse, das einen unteren Bereich aufweist, in welchem eine Gehäusewandung unmittelbar den Erdschacht bildet, und das einen oberen Bereich aufweist, in dem ein Installationsraum die Brunnentechnik aufnimmt und einen Installationsraum mit Installationsfläche für die Installation einer Pumpensteuerung, eine Bewässerungssteuerung, ein Ausdehnungsgefäß, einen Wasserfilter und einen Wasserzähler, sowie weiteres Zubehör bietet.

Because the well room is designed as a ready-to-connect solution, preferably for a garden and irrigation well, for the weather-protected well closure with installation room and area, for well and pump technology

• - a buried and watertight earth shaft, characterized in that a rubber lip seal installed in the bottom of the shaft is used to hold the well pipe in the well room in a watertight manner,
• - an attachable and lockable hood
• - At least one tank feedthrough with tapping point fed by the deep well pump via the pressure line, as well as
• - a housing which has a lower area in which a housing wall directly forms the earth shaft, and which has an upper area in which an installation space accommodates the well technology and an installation space with installation area for the installation of a pump control, an irrigation control, an expansion tank, a water filter and a water meter, as well as other accessories.

A through hole matching the well pipe is let into the earth shaft bottom, which with a rubber lip seal let into the through hole forms the receptacle for the well pipe in the shaft bottom. The rubber lip seal is designed so that it is slipped over the entire material thickness of the shaft bottom from both sides (outside and inside). It has the function of sealing the well room against water and moisture penetration from below in wet soil, heavy rain events and generally with water-bearing upper layers of the earth and to fix the well room firmly on the well pipe.

In the application, the earth shaft is preferably buried halfway below ground level, so that the upper shaft area prevents surface water from penetrating over the edge of the shaft.

The well closure can be done in this well room with the well head installation, both below GOK, but preferably above GOK.

The well head with pump control installed on the well pipe is preferably located in the upper shaft area so that the operation of the pump control is easily accessible and the control panel can be seen from the front.

The earth shaft is ideally designed in such a way that it has a high back and a low front in the upper earth shaft area in order to enable an installation surface on the rear wall in the upper inner area below the hood (installation area).

One or more sockets suitable for damp rooms can be installed on this installation surface, which are used to power the deep well pump, the pump control, the irrigation control or the connection of gardening equipment.

The upper shaft area with the installation surface can also serve as a receiving space for storing a garden hose or garden and irrigation accessories.

A hood serves as weatherproof protection against rain, dirt, etc. It is preferably lockable. A lock locks the hood together with the earth shaft. It protects against unauthorized handling and manipulation of the water and electrical installation.

The hood is preferably designed geometrically so that the upper hood area is not flat, but tapers at an angle. As a result, possible condensation / condensation water does not drip from the hood ceiling (inside) onto the electrical installation, but rather runs off over the side walls. The side walls of the hood are preferably designed so that the lower edge of the hood / hood edge protrudes in its circumference over the shaft and allows the condensation water to drip out over the upper shaft edge / shaft edge.

Furthermore, the well room is preferably equipped with a ventilation opening in the shaft area above the installation boundary line (ground level GOK) and below the installation height for the well cover to prevent condensation / condensation water and for air circulation. This also serves as emergency drainage if water leaks from the water installation inside the well room in the event of leaks and prevents water from collecting in the shaft up to the level of the well cover and thus protects the electrical installation.

A screen placed over the ventilation cut-out protects the installation space from external influences against rainwater or splash water from the irrigation sprinklers.

The cross-section of the ventilation cutout is designed to prevent small animals such as birds, rodents or insects from entering Small animal protection preferably installed in the form of a grid.

At least two tapping points are preferably provided for the connection of pipes or hose lines on the outside of the housing, with one tapping point being provided for connection to an underfloor irrigation line and a second for connecting at least one garden hose via hose couplings (such as Gardena or Geka or quick coupling or claw coupling) is used.

It is further preferred that the receiving space contains a feed device for liquid additives, in particular a fertilizer feed. Such feeds work more reliably and precisely during operation than, for example, fertilization by means of manual application of fertilizer. The fertilizer feed works according to the Venturi principle. A bypass with a venturi tube connected to the pressure line draws fertilizer from a fertilizer container by means of negative pressure and feeds it to the pressure line for irrigation. The installation area is used to attach the bypass and the Veturi nozzle. A fertilizer canister can be placed in the inner area of the earth shaft.

Furthermore, the well room with its installation room offers the possibility of installing a water filter. This holds back sand and silt particles from the pumped well water and thus protects the service water pipes and the irrigation system from clogging.

To ensure the own water supply at temperatures below 0 ° C, it is advantageous if the well room is lined and filled with insulation material. It is also advantageous if the water-carrying fittings are wrapped with a heating wire in order to prevent the water-carrying parts from freezing.

Furthermore, the well room with your installation room offers the possibility to install a water meter and to make it inaccessible to third parties through the lockable hood. Water meters are mandatory for the commercial use of groundwater.

Another advantage of this innovative invention is that the well house can be installed by the well builder without tools and great effort. This is because the well builder does not fill the last half meter to the top of the ground when backfilling the well after drilling and digs / enlarges the annulus around the well pipe with a spade a few centimeters in diameter and then puts the earth shaft over the well pipe.

The compact, slim and tall construction of the housing has the logistical advantage that the well room with all necessary installation accessories can be industrially pre-assembled from the factory and delivered to the well construction company ready for connection. The compact but tall design also means that the pump dealer does not have to send a deep well pump separately to the well, but can send the pump wrapped up in the well. The well room thus also serves as a protected package for the sensitive pump technology.

The well room includes a watertight earth shaft 1 and a removable hood 2 .

2 : There are indentations in the side walls of the earth shaft, these serve as handles when carrying the well 4th . In addition, they also serve to fix in the ground when digging deeper.

A lock with a key 5 locks the hood 2 at the earth shaft 1 , it protects against unauthorized handling and manipulation.

A borehole adapted to the well pipe is embedded in the bottom of the earth shaft. In this is a rubber lip seal 6th used. The lip seal encloses the well pipe 7th watertight and fixes the earth shaft centrally on the well pipe.

3 : A well head 8th closes the well pipe 7th from above. Through this is the riser 9 the deep well pump 10 and the pump cable 11 guided. There is a compression fitting below the well head 12 for receiving and carrying out the riser 9 screwed in. From above into the well head 8th is a detachable 3-part screw connection with a T-piece 13 screwed in.

The pump control is in the T-piece from above 14th screwed in. This switches the deep well pump depending on the pressure and / or flow 10 in and out.

Going to the right side is in the pressure line 15th a cross piece 16 used. There is an expansion vessel in the cross piece from above 17th screwed in. This protects the pump from a defect due to frequent starting of the motor, insufficient water withdrawal or leaks in the pipe system.

From the cross piece 16 Another pressure line leads out downwards (below GOK). This ends in a tank bushing 18th , in which a compression fitting 19th can be screwed in for a service water line laid underground.

From the cross piece 16 from to the right a second pressure line leads into a tank duct 18.1 . In this is a pipe elbow with a Y water distributor 20th screwed in. Two garden hoses can be connected to this water distributor using garden hose couplings.

There is a cable gland in the lower rear wall of the earth shaft 21st let in. The power line is led through this into the well, see 2 and 4th .

In the upper earth shaft area there is an installation area in the visible area on the rear wall 22nd . On this is a damp room socket 23 installed which from the power line to the cable gland 21st is powered.

An irrigation controller 24 is on the socket 23 connected. It controls the pump control according to the watering program 14th and deep well pump 10 .

On the right side of the irrigation controller are cable glands 25th embedded in the housing. These connect the solenoid valves of the irrigation system to the control.

4th : There is a ventilation opening in the back wall of the earth shaft 26th in the form of a rectangular cutout above the side indentations (handles) 4th let in. This is closed with a grid as protection for small animals. An umbrella is used for the ventilation opening to protect against rain and splash water.

The earth shaft 1 is designed in the upper area over the circumference of the outer sides in such a way that a circumferential bead 27 putting on the hood 2 serves.

The hood is designed in the ceiling area so that the hood 2 runs at a slight angle from the front and back towards the center. With this configuration, condensation does not drip from the Ceiling down, but is directed to the outside via the side walls over the lower edge of the hood.

The edge of the hood is designed in such a way that it does not sit on the bulge of the earth shaft on the front or back and drains the condensation from the well to the outside.
