DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1 and Figure 3 As shown, a municipal drainage filtering device includes a drainage box 1, a filtering component 2 is fixedly installed on the left part of the inner cavity of the drainage box 1, and a collecting and cleaning component 3 is movably connected to the right part of the inner cavity of the drainage box 1.

[0027] The rainwater and impurities flowing into the drainage box 1 can be separated and processed by the filtering component 2. When the water flows down due to gravity, it will drive several blades 25 to flip, so that the rotating shaft 24 can drive the cam 26 to rotate. When the cam 26 rotates, it will cooperate with the moving column 28 and the spring 29 to realize the vibration of the filter plate 23 and improve the filtering efficiency of the filter plate 23. This process does not require power control, is energy-saving and convenient, and has low cost. The impurities guided by the filter plate 23 can be collected and concentrated together by the collection and cleaning component 3. When the subsequent operator cleans the garbage and impurities, he only needs to lift the collection box 33 upward to a suitable position, and does not need to manually take out the collection box 33, which is more labor-saving and improves the cleaning rate.

[0028] like Figure 4 and Figure 5 As shown, the filter assembly 2 includes a grille filter plate 22, and mounting grooves 21 are provided on the left and right parts of the upper end of the drainage box 1. The lower end edge of the grille filter plate 22 overlaps with the bottom of the inner wall of the left mounting groove 21. The filter plate 23 is rotatably connected to the middle position of the left part of the inner wall of the drainage box 1, and the left part of the front and rear parts of the inner wall of the drainage box 1 is rotatably connected to the rotating shaft 24. A plurality of blades 25 arranged in a ring form are fixedly installed on the front and rear parts of the outer wall of the rotating shaft 24. A cam 26 is fixedly sleeved on the middle part of the outer wall of the rotating shaft 24, and the outer surface of the cam 26 abuts against the middle part of the lower end of the filter plate 23.

[0029] The drainage box 1 is buried underground, and its upper surface is exposed as a whole. When it rains in the city, impurities on the road surface follow the water flow and fall into the drainage box 1 through the grille filter plate 22. The filter plate 23 is tilted to intercept the impurities while guiding them into the collection box 33. The water flow falls downward due to gravity, and its downward force drives several blades 25 to flip, so that the rotating shaft 24 can drive the cam 26 to rotate, and the cam 26 drives the filter plate 23 to rotate a certain angle.

[0030] like Figure 5 As shown, a receiving sleeve 27 is rotatably connected to the bottom position of the left portion of the inner wall of the drainage box 1, a movable column 28 is slidably connected to the inner wall of the receiving sleeve 27, and one end of the movable column 28 away from the receiving sleeve 27 is rotatably connected to the left portion of the lower end of the filter plate 23, and a spring 29 is fixedly installed on one end of the movable column 28 away from the filter plate 23, and the bottom of the spring 29 is fixedly connected to the bottom of the inner wall of the receiving sleeve 27.

[0031] When the filter plate 23 rotates, the movable column 28 slides in the accommodating sleeve 27 and stretches the spring 29. When the force of the cam 26 on the filter plate 23 disappears, the elastic restoring force of the spring 29 drives the filter plate 23 to reset, thereby realizing the vibration of the filter plate 23 and enhancing the filtering effect.

[0032] like Figure 2 and Figure 4 As shown, a drainage groove 210 is opened at the left lower end of the drainage box 1, and the drainage groove 210 is located below the filter plate 23.

[0033] The filtered sewage is discharged from the drain tank 210 into the sewer.

[0034] like Figure 4 and Figure 6 As shown, the collecting and cleaning assembly 3 includes a covering plate 31, the lower edge of the covering plate 31 overlaps with the bottom of the inner wall of the right mounting groove 21, and slide grooves 32 are provided at the right positions of the front and rear parts of the inner wall of the drainage box 1, and the opposite sides of the inner walls of the two slide grooves 32 are slidably connected with a collecting box 33, which is located on the right side of the filter plate 23, and the bottom of the collecting box 33 is a filter structure.

[0035] The cover plate 31 and the grille filter plate 22 are both overlapped in the two mounting grooves 21, which are convenient for movement. When cleaning garbage, the collection box 33 can be lifted to a suitable height, and the operator can use tools to clamp out the garbage through the right mounting groove 21. There is a specific distance between the bottom of the inner wall of the two chute 32 and the bottom of the inner wall of the drainage box 1, which facilitates the collection box 33 to be fixed and suspended in the specified position.

[0036] like Figure 6 and Figure 7 As shown, mounting plates 34 are fixedly installed at the front and rear positions of the upper right edge of the drainage box 1, and a rotating rod 35 that penetrates the two mounting plates 34 and is away from each other is rotatably connected on the opposite sides of the two mounting plates 34. An adjusting rod 36 is fixedly installed on the rear part of the outer wall of the rotating rod 35, and a waterproof rope 37 is wrapped around the middle part of the outer wall of the rotating rod 35. The end of the waterproof rope 37 away from the rotating rod 35 is fixedly connected to the middle position of the upper right part of the collection box 33.

[0037] The adjusting rod 36 is rotated, and the adjusting rod 36 drives the rotating rod 35 to rotate, and the rotating rod 35 retracts and releases the waterproof rope 37, thereby realizing the rise and fall of the collection box 33. The upper right part of the cover plate 31 and the upper end of the drainage box 1 near the cover plate 31 are both provided with semicircular grooves, and the two semicircular grooves can be combined into a circular groove, and the waterproof rope 37 can move up and down in the circular groove.

[0038] like Figure 7As shown, a mounting frame 38 is fixedly installed at the rear position of the right edge of the upper end of the drainage box 1, and a slider 39 is slidably connected to the left and right parts of the inner wall of the mounting frame 38. A limit block 310 is fixedly installed on the top of the rear side of the slider 39, and a limit groove matching the limit block 310 is provided at the front end of the rotating rod 35. A spring 2 311 is fixedly installed on the bottom of the front side of the slider 39, and the front end of the spring 2 311 is fixedly connected to the front part of the inner wall of the mounting frame 38.

[0039] Move the slider 39. When the slider 39 drives the limit block 310 to insert into the rotating rod 35, the rotation of the rotating rod 35 can be limited to ensure the stability of the collecting box 33. When the collecting box 33 rises to a suitable position, the operator can stably clean the garbage. Among them, the spring 2 311 has a connecting and resetting function. After the collecting box 33 is completely cleaned, pull the slider 39 to squeeze the spring 2 311, and rotate the rotating rod 35 to release the waterproof rope 37. After the collecting box 33 drops to a certain position, release the slider 39. The elastic restoring force of the spring 2 311 can quickly drive the limit block 310 to reinsert into the rotating rod 35, thereby improving the placement rate of the collecting box 33.

[0040] The working principle of the utility model is as follows: the drainage box 1 is buried in the ground, and its upper surface is exposed as a whole. When it rains in the city, impurities on the road surface follow the water flow and fall into the drainage box 1 through the grille filter plate 22. The filter plate 23 can guide the impurities into the collection box 33 while intercepting the impurities. The water flow falls downward due to gravity, and its downward force will drive a number of blades 25 to flip, so that the rotating shaft 24 drives the cam 26 to rotate, and the cam 26 pushes the filter plate 23 to rotate a certain angle, so that the moving column 28 slides in the accommodating sleeve 27 and stretches the spring 29. When the force of the cam 26 on the filter plate 23 disappears, the elastic restoring force of the spring 29 will drive the filter plate 23 to reset, thereby realizing the vibration of the filter plate 23 and enhancing the filtering effect.

[0041] The filtered sewage is discharged from the drain tank 210 into the sewer.

[0042] When the collection box 33 needs to be cleaned, the cover plate 31 is pulled out to remove it, the slider 39 is pushed to make the limit block 310 away from the rotating rod 35, and the second extrusion spring 311 is squeezed, and the adjustment rod 36 is rotated, and the adjustment rod 36 drives the rotating rod 35 to rotate, and the rotating rod 35 retracts the waterproof rope 37, so that the collection box 33 rises. When the collection box 33 rises to a certain height, the slider 39 is released, and the elastic restoring force of the second spring 311 can quickly drive the limit block 310 to be reinserted into the rotating rod 35, so as to ensure the stability of the collection box 33, and the operator uses tools to clamp out the garbage inside. After cleaning, repeat the above operation to lower the collection box 33 to the designated position.

[0043] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
