The present invention refers to a well that can be buried for housing and protecting electro-hydraulic apparatuses, in particular for electric and hydraulic apparatuses of irrigation systems.
In order to house solenoid valves, taps, hydrants and other apparatuses of an irrigation system that need to be buried, it is known to use wells having the purpose of allowing access to such apparatuses and of protecting them from the ground and from debris. Such wells normally comprise a main body for housing the apparatuses, which has one or more lower openings, to allow the electric and hydraulic supply ducts of the apparatuses themselves to pass, and an upper opening, closed by a cover that can be walked upon and opened for inspection and maintenance operations. Known types of wells are built in various shapes and sizes, according to the number and the size of the apparatuses that they are intended to house, and they are usually obtained by forming of thermoplastic materials in a mould, since such materials are insensitive to corrosive phenomena due to burying.
Normally, in known wells, in order to be able to lift the cover and carry out an inspection on the apparatuses it is necessary to be able to have a suitable tool or, alternatively, to act manually using a hole usually foreseen on the cover itself. Such a hole, however, as well as making it difficult to open the cover, can also cause debris and dirt of various types to fall inside the well. In addition, in most known well covers there is no means suitable for preventing the cover from opening unintentionally.
Another drawback of known wells is due to the fact that, inside them, the apparatuses do not have the possibility of being arranged in an ordered manner, thus making difficult to identify them for example in the case of maintenance.
The general purpose of the present invention is therefore to solve the aforementioned drawbacks of the prior art in a simple, cost-effective and particularly functional manner.
In particular, a purpose of the present invention is to make a well that can be buried for housing and protecting electro-hydraulic apparatuses, in particular for electric and hydraulic apparatuses of irrigation systems, which is simple to open whenever it is necessary to inspect its content.
Another purpose of the invention is to make a well that can be buried for housing and protecting electro-hydraulic apparatuses in which it is not possible, or in any case it is made particularly difficult, to open the relative cover without wanting to.
A further purpose of the invention is to make a well that can be buried for housing and protecting electro-hydraulic apparatuses in which it is possible to house such apparatuses in a rational and ordered manner.
These purposes according to the present invention are accomplished by making a well that can be buried for housing and protecting electro-hydraulic apparatuses, in particular for electric and hydraulic apparatuses of irrigation systems, as outlined in claim 1.
Further characteristics of the invention are highlighted by the dependent claims, which are an integral part of the present description.
The characteristics and advantages of a well that can be buried for housing and protecting electro-hydraulic apparatuses according to the present invention will become clearer from the following description, given as an example and not for limiting purposes, referring to the attached schematic drawings, in which:
With reference to the figures, two separate example embodiments of a well that can be buried for housing and protecting electro-hydraulic apparatuses according to the present invention are shown, wholly indicated with reference numeral 10.
The well 10 comprises a main body 12 for housing the apparatuses and a cover 14, applied onto an upper opening of such a main body 12. The main body 12 can also be provided with one or more further openings 16, foreseen on the base 18 and/or on one or more of the side walls 20 of the main body 12 itself, to allow the electric and/or hydraulic supply ducts of the apparatuses contained inside the well 10 to pass. Both the main body 12 and the cover 14 are preferably made through forming of thermoplastic materials in a mould, although it is not ruled out the use of other suitable materials according to the intended use of the well 10. The base 18 of the main body 12 preferably have a larger surface than that of the cover 14 so that, when buried, the well 10 is particularly stable, effectively opposing any possible attempt of extraction from the ground. The main body 12 of the well 10 can thus be shaped, based on the preferred example embodiments shown in the figures, as a truncated pyramid (
On the cover 14 there is at least one lifting handle 22 capable of making it easier to open and close the cover 14 itself to carry out maintenance operations on the apparatuses contained in the main body 12 of the well 10. In detail, the lifting handle 22 is of the type provided with side hinging pins 24, so as to be rotatably connected to the cover 14 and pass from an operative position, in which such a lifting handle 22 is raised with respect to the cover 14 so as to be able to be gripped by a worker, to an inoperative position, in which such a lifting handle 22 is folded onto the cover 14 inside a suitably shaped cavity 26. Consequently, in its inoperative position, the lifting handle 22 is completely “embedded” in the cover 14, thus not constituting an obstacle in any way to the passage of people or vehicle above the well 10 and not foreseeing the presence of any through hole on the cover 14 itself, which could cause undesired material to enter inside the well 10.
The lifting handle 22 can thus be provided with a through hole 28 in which a tamper-proof bolt 30 is inserted that engages on the main body 12, inside a corresponding blind hole 32 foreseen on one of the side walls 20 of the main body 12 itself, when the lifting handle 22 is in an inoperative position. In this way, the lifting handle 22 is prevented from passing from the inoperative position to the operative position, stably fixing the cover 14 to the main body 12 unless one possesses the tool suitable for unlocking the tamper-proof bolt 30. The lifting handle 22, as well as the main body 12 and the cover 14 of the well 10, is also preferably made through forming of thermoplastic materials in a mould.
On one or more of the side walls 20 of the main body 12 there are also, formed in a single piece with such side walls 20, one or more housings 34 on each of which a support 36 can be inserted that is used to support the components of the apparatuses housed inside the well 10. In detail, the supports 36 are preferably intended to support the sealed connectors of the irrigation solenoid valves contained in the well 10. In irrigation systems, indeed, each solenoid valve is connected by cable to a suitable control unit, of course located outside of the well 10. The solenoid of each solenoid valve is equipped with two cables, in general 50 cm long, which must therefore be joined with other cables that are connected to the control unit. The advantage of having the sealed connectors of the irrigation solenoid valves arranged in order on the main body 12 of the well 10 is substantial since, in the case of maintenance, it is possible to immediately see which cable connects to which solenoid valve. Since in known wells the cables lie on the ground, it is often not easy to identify which cable corresponds to which solenoid valve.
The housings 34 and the relative supports 36 can also be used to “hang” the battery powered controller of the irrigation system, which is normally housed inside the well 10, thus avoiding such a battery powered controller lying on the base 18 of the main body 12 of the well 10 itself and, therefore, remaining in contact with the ground that can often be flooded.
It has thus been seen that the well that can be buried for housing and protecting electro-hydraulic apparatuses according to the present invention achieves the purposes highlighted earlier.
The well that can be buried for housing and protecting electro-hydraulic apparatuses of the present invention thus conceived can in any case undergo numerous modifications and variants, all of which are covered by the same innovative concept; moreover, all of the details can be replaced with technically equivalent elements, whilst the shapes and sizes can be whatever according to the technical requirements.
The scope of protection is therefore defined by the attached claims.
