Description

The present invention relates to the field of construction and operation of roads, namely to the construction of surface road drainage.

Storm sewage is intended for the organized collection, filtration and drainage of storm and surface water from various territories into reservoirs and reservoirs. Poor operation of drainage facilities leads to stagnation of water on the surface of the road, which significantly worsens the conditions of movement of vehicles due to a decrease in the coupling qualities of the road surface. Water on the road surface causes an aquaplaning effect, in which the car’s wheel loses traction. The greatest number of road traffic accidents caused by low adhesion qualities of road surfaces occurs precisely on wet surfaces.

The main task of stormwater is to quickly remove excess water that creates discomfort for people and causes the destruction of structural elements of buildings and structures. Storm sewage collects water from the surface of highways in low-lying places where the elements of a point catchment are mounted - storm water inlets closed with gratings to delay large debris and plant debris. A sufficiently powerful stream of water brings a lot of debris, which clogs the grate of stormwater, preventing timely drainage, rainwater stagnates, bringing great inconvenience.

In the patent CN 102127929 (A) dated 07/20/2011, adopted as a prototype, a self-cleaning device for a storm sewer grate is provided, which prevents blocking of it with waste. The parallel grooves of the grill are cleaned with the teeth of a comb attached at one end to a bucket with a valve and the other to a counterweight. During rain, the bucket is filled with water and pulls the teeth of the comb in one direction, when the bottom reaches the bucket, it is freed from the water, and the teeth under the influence of the counterweight return to their original position.

The disadvantage of this device is that it cannot perform the functions assigned to it. The description indicates that after opening valve 12, all water will flow out of bucket 8. In reality, water flows out gradually, the bucket becomes lighter, the moment comes when the bucket 8 is balanced with the counterweight 7, it rises above the limit switch 9, the valve 12 closes, does not letting the water merge to the end. The counterweight 7 does not outweigh the partially filled bucket 8, and the teeth of the comb 5 will not return to their original position. In this average equilibrium position, the device will remain, because the amount of water entering the bucket at any time will be equal to the amount of water flowing out of it through the slightly open valve 12. The device will not return to its original position only after the rain ends, when water flows out of the bucket through leaks.

The aim of the invention is the development of a workable device for self-cleaning the gratings of storm sewers from clogging with waste. The solution of this technical problem is provided by the fact that the design of a device for self-cleaning the grate of storm sewers is proposed.

The essence of the claimed technical solution is illustrated by a description of an example of its preferred implementation in combination with the accompanying drawings. The same item numbers are used throughout the description and in all drawings to refer to the same components and parts. Numbering is made in the order of mention in the description.

In FIG. 1, 2 show two projections of a device in its initial position, in FIG. 3 - the device is in the state of greatest deviation of the fingers of the comb from the initial position. FIG. 4, 5 show samples of storm sewer grates for which the device is applicable. In FIG. 6 shows an enlarged capacity with a door.

The device is a mechanism containing a comb 1 with fingers 2, mounted on a structure 3 having a swivel 4 with the frame 5. The fingers 2 are displayed in parallel transverse grooves 6 of the grate 7 of the storm water inlet 8 of the storm sewer. The structure 3 is connected to a cable 9, on one end of which a container 10 is fixed with a door 11, and on the other a counterweight 12. The mass of the counterweight 12 is greater than the empty container 10, but less than the same container filled with water. The cable 9 passes through the guide blocks 13 and 14, mounted on the frame 5. The door 11 of the tank 10 is mounted with the ability to move along the grooves 15 and fixation in the open position with a ball lock.

The device operates as follows: from the initial position shown in FIG. 1, 2, it is displayed when the container 10 is filled with water during rain. In this case, the container 10 outweighs the counterweight 12 and falls down, while moving the combed waste 1 from the grate 7 to the side of the road with a comb 1. At the lowermost point, the cable 16, mounted on the grate 7, raises the door 11 through the grooves 15, which is locked in the open position with a ball lock, the water completely flows out due to the inclined bottom of the container 10. An empty container 10 is lighter than the counterweight 12, and it rises upward, releasing comb 1 to its original position. In the extreme upper position of the container, the handle 17 of the door 11 of the container 10 abuts against the grate with a cross member 18 and, overcoming the resistance of the ball lock of the open position of the door 11, forcibly closes it. The device has returned to its original position and is ready for a new cycle, further operations are repeated. The device works until the flowing water fills the tank. If at the end of the rain there is not enough water in the tank to fill it, the device with the door closed will stop in one of the intermediate positions, due to the door leakage, water will gradually leak out of the tank and the device will return to its original position.

The invention ensures the timely removal of water from the carriageway of roads without the participation of maintenance personnel due to the automatic cleaning of the protective grate of the storm water inlet of storm sewers from waste. The device does not require a power source and control, as well as maintenance, it will increase the throughput of roads in adverse weather conditions. In order to avoid rusting the mechanism, working in conditions of high humidity, its parts are made of plastic materials. During the transition period, spring and autumn freezing water at night will not damage the tank, as It is made using elastic tensile materials based on rubber or plastic. The fingers of the comb protruding above the roadway are made of used tires so as not to damage the tires of passing cars.

The technical result of the claimed invention is to increase the capacity of roads in adverse weather conditions due to the timely removal of water from the carriageway without the involvement of maintenance personnel.

The specified technical result is achieved through the use of a device for self-cleaning the grate of storm sewers from clogging with loose garbage.

New significant features of the claimed invention are:

- increase the throughput of roads in adverse weather conditions;

- timely removal of water from the roadway without the involvement of staff;

- A self-cleaning device for the storm sewer grate from clogging with waste was developed.
