Description

Underground container.

Object of the invention

The present invention relates to a container, of those destined to the collection of urban solid waste, underground container that is trained to house in your inside a pair of containers with conventional wheels, of large capacity, such as 1,100 liters each, at which is accessed through respective mailboxes established in the underground container lid, which is liftable, just like the base on which conventional containers rest with wheels, to allow the extraction of the latter and their corresponding emptying.

The object of the invention is to achieve a remarkable simplification in the structure of the container and a great ease of maneuver to move from one to the other of the two extreme positions, waste introduction and collection of the same.

Background of the invention

Underground containers are known materialized in a concrete pit, of appropriate dimensions, at whose bottom a platform is established capable of supporting two or more rolling containers, while at the level of its mouth it establishes a second platform, acting as a lid for the pit, with access boxes to each of the rolling containers interiors.

To mobilize the aforementioned platforms, they use several hydraulic cylinders as well as vertical guides, said hydraulic cylinders being driven by an outlet of pressure conveniently set in the vehicle of pick up

These solutions, besides being structurally complex, generate a direct dependence between the container and the collection vehicle, which forces the latter to have means of connection with the hydraulic cylinders of the container and that it also involves a slow and complex connection maneuver, which it implies a notable loss of time by the operators of pick up

Description of the invention

The underground container that the invention proposes to solve the problem fully satisfactorily previously exposed in the different aspects commented.

To do this, more specifically and starting from the basic and conventional structuring according to which in the same two mobile platforms participate, one lower for settlement of the rolling containers and another superior one in functions of cover with its corresponding mailboxes, the invention focuses on the use of a hydraulic jack, in vertical arrangement and centered, which acts simultaneously on both platforms and that It also acts as a mechanical link between them, keeping them permanently distanced from the preset level determined by the size of the rolling containers that have to be located on the lower platform.

This hydraulic jack is telescopic type for minimize its dimensions in a situation of maximum retraction.

The guidance system has also been remarkably  simplified, so that replacing the classic guides telescopic the lower platform incorporates marginal rollers, of free rotation, which rest on the side walls of the pit, sliding tightly over them.

The existence of a auxiliary box, located laterally with respect to the pit and with independent access, in which the hydraulic group of said cat drive, conveniently communicated with this last through a pipe embedded in the concrete itself constituting the pit, said hydraulic equipment being driven to turn by an electric motor conveniently connected to the network general supply through a lock switch that avoid undue drives on said group.

The hydraulic jack feed circuit will be assisted by non-return valves that avoid the one that, before a failure in the equipment, a reduction takes place unforeseen platforms.

According to another of the characteristics of the It is envisaged that at the bottom of the pit a sump connected to the auxiliary box, so that through of the latter the elimination, by aspiration, of any accumulation of fluids that occur in the pit, such as for example the periodic washing water thereof.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:

Figure 1.- Shows a representation schematic side elevation and section of a container underground made in accordance with the purpose of this invention, which appears in a closed situation, that is to say in waste introduction position.

Figure 2.- Shows the same set of the previous figure, now according to a schematic representation in plant.

Figure 3.- Shows, finally, a representation similar to that of figure 1, but in which the container appears in elevation for its platforms, that is to say in a waste collection position.

Preferred Embodiment of the Invention

In view of the figures outlined you can be observed as the underground container that the invention proposes it is constituted from a pit (1), made of concrete armed, with perfectly flat side and internal walls (2) and vertical, as they have to act as sliding guides for the mobile elements of the container, consisting of two platforms (3) and (4), a lower (3) in base functions of support for a pair of conventional and rolling containers (5), and a higher one (4), in cover functions, on which establish the classic mailboxes (6) operatively faced with the containers (5), both platforms (3) and (4) being duly distanced so that they can stay among them containers (5), as shown in figures 1 and 3, and solidly stiffened with the collaboration of a robust column central (7), which is part of a hydraulic jack (8) in turn in solidarity with the bottom (9) of the pit (1), also available centered.

Laterally with respect to the pit (1) and integrated with it a casket (10) is established, with its corresponding upper access door (11), properly sized cabinet to house the hydraulic drive equipment (12) inside of the jack (8), hydraulic equipment in which an engine participates electric governed from a control unit, not represented in the drawings, through a key switch duly connected to the general power supply network.

Within the constitutive concrete mass from the pit (1) a pipeline (13) is established that communicates the casket (10) with the lower end of the hydraulic jack (8), for hydraulic feeding of the latter, and in the area upper-side of said casket (10) is established a cable gland (14) for electric communication of the motor Hydraulic unit drive with the control unit, conveniently located for easy access to it.

As previously stated, the side walls (2) of the pit (1) act as guides for sliding the lower platform (3), for which purpose the latter counts on its edges with rollers or
wheels (15).

As a complement to the structure described, provided in the background that, through a conduction (17) also embedded in the mass of constitutive concrete in the pit (1), it open towards the upper area of the auxiliary box (10), finishing off in a socket (18) for coupling a team of aspiration that allows the elimination of fluids that may accumulate at the bottom of the pit (1).

The hydraulic jack travel (8) will be duly established so that in a situation of maximum elevation the lower platform or base platform (3) is flush with the soil (19), allowing easy removal of containers rolling (5), and between the perimeter of the cover (4) and the mouth from the pit (2) sealed coupling means shall be established that ensure the tightness of said pit both in terms of the entry of water or waste into it as possible Bad smells

Although this description has been made in based on a hydraulic drive system, the invention allows also a practical realization based on zippers and pinions.
