Description

The The present invention relates to a positioning device for at least one aquatic plant.

These Water plants are for achieving a visually appealing body of water, like a river, river section, area of a lake or pond permanently position. Also for placing the aquatic plant at a location suitable for growth is the positioning device intended.

The DE 93 08 021 discloses a swimming ring system for aquatic plants with a floating net for underwater plants, which is arranged in the position of use below a water surface. Only the floating net without the underwater plant drives in the use position below the water surface. To support an underwater plant from sinking to a body of water, a connection to the swimming ring system is required.

at this generic positioning At least one component of the device remains on the surface of the water or is typically visible in the use position. This destroyed a natural overall impression of the water.

It It is therefore an object of the present invention to provide a positioning device to provide for aquatic plants within a body of water completely below the water surface is to be arranged.

These Task is inventively technically simple Means solved by the features of claim 1.

Of the The term aquatic plant here includes both permanent or mostly aquatic plants, plants predominantly or completely below the water surface grow as well as free-swimming or rooted plants.

A Base of the positioning device according to the invention can support, hold on or essentially the aquatic plant contactlessly within a predetermined section of water, For example, the base is merely a component of the aquatic plant fenced.

From Advantage for the positioning device according to the invention is that the base provides a variable buoyancy, wherein the positioning device with the aquatic plant in the floating state can be transferred is. Consequently, the entire positioning device below the surface of the water can be arranged and in predetermined depth of water above the bottom of the river be spent.

Around a particularly favorable for the aquatic plants Place within the water or a growth-promoting To adjust the arrangement of the roots, the positioning device be developed so that the base of limbo Reversible into a sinking state or a climbing state can be transferred is. This can be both a volume and a mass change the base be brought about, for example, a to achieve the desired water depth of the positioning device. Also, this water depth can be reversed by the reversibility adjusted, for example, by increasing the plant mass the lift of the base has become too high or low.

According to a particularly advantageous embodiment of the positioning device according to the invention, the base has a gas-storing reservoir, wherein the gas pressure can be regulated with a valve. The gas comprises any chemical inert to the reservoir, in particular gases having a density at typical water temperatures of less than 1 gcm ^-3 . The gas may be air, nitrogen, a noble gas or carbon dioxide. The reservoir may provide at least one cavity in the form of a rigid or flexible chamber, which may be located inside or outside the base. The reservoir may extend over the entire base or form a subsegment of the base. The valve is used to set a predetermined, variable pressure of the gas in the reservoir. In particular, the gas can be drained off, or the gas can be filled in and / or postdosed. It is not necessary to introduce the same gas already present in the reservoir into the reservoir.

Around later changes in position of the invention Facilitate positioning within a floor area, the reservoir is connectable with a hose. This hose can for example, be permanently connected to the reservoir and a End of the hose to the edge of the water range. On the one hand is a relative short-term and / or by mere pulling on the hose permanent change of position within the water possible. Thus, a wading and / or fiddling in the Water ecology be avoided. Upon entering the water can be waived and the risk of injury to a pond skin or the like is effectively minimized. On the other hand can at a Hose end a combined inlet and outlet valve are provided that used to change the gas pressure in the reservoir and thus the positioning device "dive" into another water depth.

to Improving the situation in terms of their orientation below the surface of the water is the positioning device formed in the form of a flexible pot. A deepening of this Pot serves as a base and is provided by a bag. The bag is made of a waterproof and water resistant Material for example a so-called natural product such as rubber or jute or a plastic such as PVC. The bag can be one-piece or multi-piece. A controlled cultivation of rooting aquatic plants can by taking a root ball be reached in the bag. By regular "copying" so cut back of rootball can reduce the aquatic plant to a certain size and weight are limited. The rooting aquatic plant like one Water lily or a shrub can therefore be even later to a suitable place of ornamental or swimming water pond be spent. The aquatic plant "anchors", so to speak not on the riverbed.

The open end of the bag is attached to a carrier and is almost a pot edge. The vehicle is a right one rigid construction. The carrier may consist of one consist of water floating material. For example, in the bag introduced a non-floating aquatic plant, drives the inventive Positioning device usually arranged by the pot edge Carrier with the open end of the bag pointing upwards in the water. In particular, the carrier as Reservoir be formed.

Of the Carrier and reservoir can be considered as separate components be designed the positioning. This is a cheaper Exchange of individual parts of the positioning possible. A particularly simple, durable and detachable connection between the carrier and the reservoir is such that the carrier has a bore which is the valve of the Reservoir absorbs and which the hole when connecting to the Reservoir permeates.

at a multi-part embodiment of the positioning device the buoyant carrier is also to one side towards, for example, an outward or downward Side, open, thus forming a recess, receptacle, groove or the like, within of which the reservoir is attachable to the carrier.

A very rigid construction with low weight comprises an annular carrier made of a plastic such as polyvinyl chloride, polyurethane, other polymer compounds or Combinations thereof.

to further position stabilization of the positioning can a corrosion resistant trim weight, for example manufactured made of stone material, held by the carrier or bag become. Advantageously, the trim weight is at the bottom arranged the positioning device, in particular close to the pot bottom, for example, on the bottom of the bag.

Of the Bag may consist of a film or a net-like mesh. Advantageously, the bag is of a fine mesh or a cloth-like fabric. The latter bag It also has the advantage of rooting out of the bag can. Also, nutrients and air from the surrounding can Water water in the bag and "waste" out the bag to be washed or flushed out. This reduces a decay formation considerably and makes a qualitative Improvement of the water possible.

A Another embodiment of the invention provides that a Root substrate is absorbed by the bag. Root-forming aquatic plants can provide something like an artificial shore become. The root substrate includes soil, potting soil or anything permanently water resistant, suitable as a root stop and humus rich material. By lowering the positioning device can root bales for a particular aquatic plant to a particular, optimal for growth, Water depth can be brought. An otherwise only superficially settled For example, an aquatic plant can also be found in a middle of the water be positioned.

Favorable Way, this root substrate is an open-pored plant granules. The larger surface of this root substrate allows better rooting with better Plant growth. Also, the plant granules can fertilizer take or provide the water plant. The plant granules and / or the root system acts as a kind of bioactive Water filter.

to Control of the water depth achieved when lowering or a change in position to a lower depth of water is a Measuring rod provided with depth scale, for example, on the device is releasably secured to the base. Preferably, the Measuring rod supported by the root substrate, with the origin the depth scale is to be arranged at root level.

Also, a holder can be attached to the positioning device. In use position - ie located below the surface of the water - can, for example, by a fixed to the bracket rope or the like, the positioning of the water edge to a bestimm or the region of the water body.

a Another aspect relates to a method for arranging at least an aquatic plant within a water body. It is It is an object of the invention, one optimal for the growth of the aquatic plant Reach permanently. For this purpose, it is provided according to the invention the aquatic plant by means of a positioning device of the above-described To arrange species within the water.

Especially can with this method and / or the positioning a Water plant to a deep point of the water body or on the Waterbed can be spent. This position is for example a frost-proof area of a fishpond. Thus, the aquatic plant be spent in a winter parking position. Saves this lowering an autumnal mountains and storage of aquatic plants for example in basement, shelter or garage. Especially large water lily perennials so do not need additional spring be returned to the water. The aquatic plants remain after any "copying" in the water.

The The present invention thus relates to a method for arranging at least one aquatic plant within a body of water, wherein the aquatic plant is fixed to a positioning device and the positioning device according to one of the above Embodiments is designed.

It Another object of the present invention is aquaculture to improve. This object is achieved according to the invention solved that one of the above positioning devices of the present invention for aquaculture becomes.

Further Features and advantages of the invention will become apparent from the following Description of several embodiments and from the drawings, to which reference is made below. Show it:

1 a first embodiment of a positioning device according to the invention in a perspective view;

2 a second embodiment of a positioning device in cross-sectional view;

3 a representation of a third embodiment of a positioning device according to the invention;

4 A fourth embodiment of a positioning device in side sectional view; and

5 an elevational view with another embodiment of a positioning device in the use position.

Unless otherwise stated below, the following description always refers to all embodiments of the 1 to 5 , wherein like reference numerals always describe the same structural features.

1 shows a positioning device 10 for aquatic plants 11 with a pot-shaped base 12 , The positioning device 10 is introduced in use position in a body of water and completely below the surface of the water 14 arranged. Consequently, at the surface of the water 14 exclusively a natural way out of the water protruding component of the aquatic plant 11 to see in particular their floating leaves and their flowers. The pot-like base 12 surrounds the aquatic plant 11 to arrange them within a particular section of the pond exemplified here.

The base 12 the positioning device according to the invention 10 is here designed such that a by arrows in 1 symbolized buoyancy by water displacement can be achieved. This buoyancy is inventively to change so that the positioning 10 including water plant 11 into limbo. The positioning device 10 "Stands" with the aquatic plant 11 freely above the water bottom, without losing the water surface 14 to break through.

At the in 2 The embodiment shown is the positioning device 10 executed in several parts. A base shown in cross-section 12 is approximately U-shaped and takes a root substrate 38 in the form of an open-pored plant granules. At the back of the base 12 , which is approximately a rectangular blank of a rigid plastic film, is a gas-tight reservoir 16 arranged. This reservoir 16 Expands differently depending on the prevailing gas pressure, as illustrated by the arrow. The gas pressure is here by means of a valve 18 adjustable. Is the positioning device 10 Within a body of water, there is a change in water displacement by changing the gas pressure in the reservoir 16 to reach. Similar to a swim bladder, as the gas pressure increases or the water pressure decreases, an upper portion of the approximately U-shaped reservoir inflates 16 out. The plant granulate arranged below this section acts to stabilize the position like a trim weight 36 ,

To the valve 18 An air pump is connectable to the gas pressure in the reservoir 16 to increase. The reservoir 16 expands and displaces a corresponding volume of water when it is introduced into a body of water. This creates a lift in an order of magnitude of the displaced water mass and the positioning device 10 ascends. Ascent and descent in connection with this invention means that the device according to the invention assumes a smaller or larger depth of water within the water body.

A slightly different embodiment is in 3 shown. The trained as a pond island positioning 10 includes a plate-shaped base 12 , To the base 12 is a hose-like reservoir 16 molded, which is shown in sectional view. The one from the reservoir 16 before given pot takes up the aquatic plant. A hose 20 is gas-tight to the reservoir 16 connected. To set a certain buoyancy when inserting the positioning device 10 in the pond is over the hose 20 the amount of gas or the gas pressure variable. A hose end 24 is for this purpose provided with a three-way cock, with a setting position as an exhaust valve 22 to reduce the gas pressure in the reservoir 16 can be used. Another connection of the three-way valve is a pump 25 to the hose 20 connected. By means of the pump 25 Air gets into the reservoir 16 encouraged, for example, the device 10 be transferred from the floating state in the climbing state.

The hose 20 can also be conveniently attached to the shore as a sort of "leash" or used to tow the island to another location in the pond or out of the pond and / or into it.

A modular positioning device 10 for aquatic plants is in 4 shown in cross-sectional view. One Base 12 is here by a carrier 30 and a net-like bag 26 educated. The open end 28 of the bag 26 is on the approximately circular carrier 30 releasably secured. The carrier 30 has a U-profile in cross section, which remains open radially down to the reservoir 16 take. A neck of the reservoir 16 protrudes through a hole 32 on the carrier 30 , At the neck is a hose 20 as in 3 shown attachable. With appropriate expansion of the reservoir 16 by increased gas pressure becomes the reservoir 16 sufficiently supported by the U-profile. The net-like bag 26 is made of a fabric 37 manufactured, which is prefabricated as an endless tube. This endless tube comes with the carrier 30 connected, correspondingly cut to a predetermined length and welded near the resulting cut edge, glued, knotted or the like to the bag 26 provide. This creates a constriction 35 at the "bottom" end, at the open end 28 the bag opposite end, out. This in the position of use of the positioning 10 The lowest point in the body of the bag receives several pieces of metal such as pebbles, which as trim weights 36 to stabilize the position.

For depth determination is on the carrier 30 the positioning device 10 also a dipstick 40 appropriate. Its measuring scale is provided with luminescent numerals, which are clearly visible from a considerable distance - for example, from the shore. The dipstick 40 is detachable on the carrier 30 arranged so as not to impair the overall impression of the water body. After setting the desired water depth, the dipstick becomes 40 taken off and placed the island at its desired place in the water. Alternatively, the scale is imprinted and can be covered with a slowly water-soluble luminous color, so that the dipstick 40 after a short time is no longer visible. Another variant of the dipstick 40 is in the root substrate 38 pluggable and divided into approximately equal sections. The dipstick 40 is cut to the desired depth and thus does not protrude after lowering the island over the surface of the water 14 in addition or is covered by protruding from the water plant parts. For cutting to length, the dipstick 40 be provided between the sections with a predetermined breaking point. The sections are colored differently and / or covered with the water-soluble color.

An advantageous way of placing a positioning device 10 is in 5 seen. The rectangular-shaped positioning 10 is shown in the use position and below a here approximately oval extending water surface 14 arranged. Around the island 10 within a certain water region 15 to arrange, is a holder 42 provided with a ground anchor 44 is connectable. This serves the ground anchor 44 less the setting of a predetermined water depth. This is the buoyancy of the island 10 so changeable, that the island 10 in a floating state and reversible in a sinking or in a climbing state can be transferred. The holder 42 is designed as eyelet, hole and / or slot and also serves to attach an anchorage 43 , which allows a permanent and secure connection to the shore of the water.

The present invention discloses a positioning device for at least one aquatic plant, which is to be arranged in the position of use variable between the water surface and a bottom area. The water depth is permanent through a variable buoyancy of the positioning adjustable. The invention relates to a method for positioning aquatic plants within a body of water, which uses one of the described positioning devices. Finally, the method and the positioning device for aquaculture according to the invention are used. In this way, in particular a larger acreage can be created in addition to a naturally existing shore area for the cultivation of aquatic plants.
