Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of road drainage, in particular to a drainage channel debris clearing structure with backwashing. Background Art
[0002] During the construction of municipal engineering projects, it is often necessary to lay drainage branches on both sides of the road surface for drainage. The drainage branches will be connected to the main drainage channel. A row of rainwater grates are generally placed on the upper side of the drainage branch to drain water and initially block some large impurities. However, there will still be some small impurities that fall through the rainwater grates into the drainage branch. In the process of converging to the main drainage channel, they are further filtered through the filtration structure. However, once the garbage on the filtration structure accumulates, it will seriously affect the drainage efficiency. Utility Model Content
[0003] In order to solve the above technical deficiencies, the utility model provides a drainage channel debris cleaning structure with backwashing, which has a backwashing function to clean up garbage on a filter plate and improve drainage efficiency.
[0004] The utility model discloses a drainage channel cleaning structure with backwashing, comprising a foundation pit, a cover is arranged on the foundation pit, a main drainage channel is arranged on one side of the foundation pit, the main drainage channel is communicated with the lower part of the foundation pit, a drainage channel branch is arranged on the other side of the foundation pit, a row of rainwater grates is arranged on the upper side of the drainage channel branch, a filter plate is horizontally arranged at the middle part of the drainage channel branch, filter holes are arranged on the filter plate, the filter plate separates the drainage channel branch into an upper channel and a lower channel, the lower part of the foundation pit is communicated with the lower channel of the drainage channel branch by arranging a No. 1 through hole, a No. 1 electric control valve is arranged on the No. 1 through hole, and the upper part of the foundation pit is arranged by arranging a No. 2 through hole. The through hole is connected with the upper channel of the drainage branch, a filter is arranged in the middle of the foundation pit, and also includes a water tank, a tap water pipe is connected to the water tank, a No. 2 electric-controlled valve is arranged on the tap water pipe, the bottom of the water tank is connected with the lower channel of the drainage branch through a pipeline, a No. 3 electric-controlled valve is arranged on the pipeline, a No. 1 liquid level sensor is arranged on the lower side of the interior of the water tank, a No. 2 liquid level sensor is arranged on the upper side of the interior of the water tank, a No. 3 liquid level sensor is arranged on the lower side of the filter plate, and the No. 1 liquid level sensor, the No. 2 liquid level sensor, the No. 3 liquid level sensor, the No. 1 electric-controlled valve, the No. 2 electric-controlled valve and the No. 3 electric-controlled valve are all electrically connected to the controller.
[0005] The principle of the above structure is that when it rains, rainwater carries debris into the drainage channel branch, and the rainwater enters the lower channel of the drainage channel branch through the filter holes on the filter plate, and the impurities are trapped on the filter plate. At this time, the controller controls the No. 1 electric control valve to open and drain normally. When the impurities on the filter plate accumulate a lot after a period of time, the No. 1 electric control valve is closed by the controller, and the rainwater accumulates in the lower channel of the drainage channel branch. When the rainwater submerges the No. 3 liquid level sensor, the controller controls the No. 3 electric control valve to open, and the water in the water tank quickly enters the lower channel of the drainage channel branch, so that the water reversely flushes the impurities on the filter plate. The impurities flushed from the filter plate flow into the foundation pit through the No. 2 through hole with the water flow, and the impurities are left on the filter net for collection. When the No. 1 liquid level sensor in the water tank detects that the water level in the water tank is low, the controller controls the No. 1 electric control valve to open and close the No. 3 electric control valve at the same time to restore to the normal drainage state. The controller can control the No. 2 electric control valve to add a certain amount of tap water into the water tank according to the electrical signal of the No. 2 liquid level sensor.
[0006] In order to reduce the use of tap water, an upwardly inclined shell is provided around the top of the water tank, and a water collection hole is provided on the top of the water tank. When it rains, the shell increases the area for rainwater collection, and the collected rainwater enters the water tank through the water collection hole, thereby reducing the use of tap water.
[0007] The utility model provides a drainage channel cleaning structure with backwashing, which has the beneficial effect that when impurities are accumulated on the filter plate, the impurities on the filter plate can be washed away by backwashing and collected by the filter screen, thereby improving the drainage effect.

[0012] The principle of the above structure is that when it rains, rainwater carries debris into the drainage channel branch 6, and the rainwater enters the lower channel 5 of the drainage channel branch 6 through the filter holes 19 on the filter plate 7, and the impurities are trapped on the filter plate 7. At this time, the controller controls the No. 1 electric control valve 4 to open and drain normally. When more impurities accumulate on the filter plate 7 after a period of time, the No. 1 electric control valve 4 is closed by the controller, and rainwater accumulates in the lower channel 5 of the drainage channel branch 6.

The water quickly enters the lower channel 5 of the drainage branch 6, so that the water reversely flushes the impurities on the filter plate 7. The impurities flushed from the filter plate 7 flow into the foundation pit 3 through the No. 2 through hole 21 along with the water flow, and the impurities remain on the filter screen 2 for collection. When the No. 1 liquid level sensor 10 in the water tank 11 detects that the water level in the water tank 11 is low, the controller controls the No. 1 electric-controlled valve 4 to open and close the No. 3 electric-controlled valve 17 at the same time to restore to the normal drainage state. The controller can control the No. 2 electric-controlled valve 13 to add a certain amount of tap water into the water tank 11 according to the electrical signal of the No. 2 liquid level sensor 16.
[0013] In order to reduce the use of tap water, a shell 14 inclined upward is provided around the top of the water tank 11, and a water collection hole 15 is provided on the top of the water tank 11. When it rains, the shell 14 increases the area for collecting rainwater, and the collected rainwater enters the water tank 11 through the water collection hole 15, thereby reducing the use of tap water.
