[0002] At present, most of the interception devices in China are set at the outlet of the drainage pipe flowing into the river, and direct filtration is often used as the main method. However, during the process of sewage transportation, there are still a lot of sediments and dirt remaining, causing pollution and blockage. The interception device set at the network outlet can effectively intercept dirt at the end of the network where it enters the river, that is, directly place a filter net at the outlet of the pipeline to simply filter the dirt at the drainage outlet.

[0003] In the prior art, at the outlet of the drainage pipe flowing into the river, although the filter net can be set to filter dirt such as sediment to avoid directly discharging dirt such as sediment into the river, after the filter net at the outlet of the drainage pipe is used for a period of time, a large amount of dirt such as sediment is likely to accumulate at the outlet of the drainage pipe, and it is necessary to clean the outlet of the drainage pipe regularly by manual labor. This process is not only time-consuming and laborious, but also results in a low cleaning efficiency of dirt such as sediment at the outlet of the drainage pipe, and dirt such as sediment is likely to block the filtering holes, thus affecting the passage of water flow and further affecting the drainage efficiency of the drainage pipe.

Then, under the interaction of the pulley 5, the belt 501 and the pulley 502, the reciprocating lead screw 4 can be driven to rotate, playing a role in power transmission.

[0035] As Figure 1-8 shown in the figure, two fixing plates 704 are symmetrically and fixedly installed on the top of the shovel frame 307. A one-way lead screw 701 is movably embedded on the opposite side of the two fixing plates 704 close to the thread bar 305.

By starting the waterproof motor 7, its output shaft drives the one-way lead screw 701 to rotate. Then, under the interaction of the one-way lead screw 701 and the threaded push plate 703, and with the cooperation of the guide rod 702, the threaded push plate 703 can move along the threaded direction of the one-way lead screw 701, thereby pushing the sediment and other dirt on the shovel frame 307 towards the square groove 308.

[0036] As Figure 1-8 shown in the figure, a connecting pipe 2 is fixedly installed on one side of the square pipe 1. A through groove 103 is opened on one side of the square pipe 1 close to the top. A through groove 104 is opened on one side of the square pipe 1 close to the bottom. The square pipe 1, the through groove 103, the connecting pipe 2 and the through groove 104 are connected and communicated. Through the above settings, when the water flow inside the square pipe 1 enters the inside of the connecting pipe 2 through the through groove 103, after being filtered, it can flow back into the inside of the square pipe 1 through the through groove 104.

[0037] As Figure 1-8As shown, a filter screen frame 201 is movably embedded inside the connecting pipe 2. A limiting block 203 is fixedly installed on one side of the connecting pipe 2 near the top. An L-shaped rod 202 is fixedly installed on one side of the filter screen frame 201 near the top. The outer surface of the L-shaped rod 202 near one end is movably embedded inside the limiting block 203. A third through groove 205 is formed on the other side of the filter screen frame 201 near the top. Through the setting of the third through groove 205, it is convenient for sundries such as sediment to enter the filter screen frame 201. Through the setting of the filter screen frame 201, it plays a role in filtering sundries such as sediment. Through the setting of the L-shaped rod 202 and the limiting block 203, it plays a role in limiting the filter screen frame 201, making the third through groove 205 correspond to the inner wall of the connecting pipe 2.

[0038] As Figure 1-8 shown, multiple rubber rods 405 correspond to the holes of the filter screen plate 101. Through the above setting, when the rotating rod 404 drives the rubber rods 405 to rotate, it is convenient for the rubber rods 405 to insert into the holes of the filter screen plate 101 and push out the sundries such as sediment inside the holes of the filter screen plate 101.

[0039] As Figure 1-8 shown, a protective cover 3 is fixedly installed at the position of the waterproof motor 302 on the top of the square pipe 1. Through the setting of the protective cover 3, it plays a certain protective role.

[0040] As Figure 1-8 shown, a cover plate 204 is movably embedded on the top of the filter screen frame 201. A handle is fixedly installed on the top of the cover plate 204. Through the setting of the cover plate 204, it prevents external garbage from entering the inside of the filter screen frame 201. Through the setting of the handle, it is convenient to open the cover plate 204.

[0041] As Figure 1-8 shown, the opening at the bottom of the shovel frame 307 is set as an inclined surface. Through the above setting, it is convenient for the shovel frame 307 to shovel up the sundries such as sediment at the bottom of the filter screen plate 101.

[0042] Working principle: When in use, the filter screen plate 101 needs to be installed at the outlet position of the drainage pipe. By starting the waterproof motor 1 302, its output shaft drives the reciprocating lead screw 1 303 to rotate. Then, under the interaction of the reciprocating lead screw 1 303 and the thread strip 1 305, and with the cooperation of the guide rod 1 304, the thread strip 1 305 can move downward along the reciprocating lead screw 1 303, synchronously driving the round rod 306 and the thread strip 1 305 to move downward. The round rod 306 can drive the connecting sleeve 605 to move. Then, under the cooperation of the connecting sleeve 605, the rotating shaft 604, the connecting block 603 and the movable rod 602, the movable rod 602 can be driven to slide downward along the V-shaped chute 601, thereby pushing the round rod 306 to move towards one end, compressing the spring 309, and synchronously moving the shovel frame 307 towards the filter screen plate 101 side. The shovel frame 307 shovels up the sediment and other dirt deposited at the bottom of the square pipe 1. In this way, there is no need for manual cleaning, which saves time and effort and improves the cleaning efficiency of the sediment and other dirt at the drainage pipe outlet. When the shovel frame 307 touches the bottom of the square pipe 1, the thread strip 1 305 can drive the shovel frame 307 to move upward through the action of the reciprocating lead screw 1 303. Under the action of the V-shaped chute 601, when the shovel frame 307 moves to the top of the square pipe 1, the shovel frame 307 can be made to be in close contact with the filter screen plate 101, making the square groove 308 correspond to the through groove 1 103. Then, start the waterproof motor 2 7, and its output shaft drives the one-way lead screw 701 to rotate. Then, under the interaction of the one-way lead screw 701 and the thread push plate 703, and with the cooperation of the guide rod 3 702, the thread push plate 703 can move along the thread direction of the one-way lead screw 701, thereby pushing the sediment and other dirt on the shovel frame 307 towards the square groove 308, so that the sediment and other dirt enter the connecting pipe 2 through the through groove 1 103 and enter the inside of the filter screen frame 201 through the through groove 3 205. The filter screen frame 201 filters the sediment and other dirt, and the water flows back into the square pipe 1 through the connecting pipe 2. In this way, it is convenient to collect the sediment and other dirt and facilitate subsequent cleaning. Synchronously, through the rotation of the reciprocating lead screw 1 303, the pulley 1 5 can be driven to rotate. Then, under the interaction of the pulley 1 5, the belt strip 501 and the pulley 2 502, the reciprocating lead screw 2 4 can be driven to rotate. Then, under the interaction of the reciprocating lead screw 2 4 and the thread strip 2 402, and with the cooperation of the guide rod 2 401, the thread strip 2 402 can be driven to move along the thread direction of the reciprocating lead screw 2 4, thereby driving the rotating rod 404 to move up and down, synchronously driving the gear 407 to move. Then, under the interaction of the gear 407 and the rack 102, the gear 407 can be made to rotate, synchronously driving the rotating rod 406 and the rotating rod 404 to rotate, so that when the rotating rod 404 rotates, it is inserted into the holes of the filter screen plate 101, and the sediment and other dirt in the holes of the filter screen plate 101 are pushed out. In this way, the holes of the filter screen plate 101 can be prevented from being blocked, which facilitates the passage of water flow and further improves the drainage efficiency of the drainage pipe.
