[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 - Figure 5 The present invention provides a technical solution: a water pump filtration device for water conservancy management, comprising a water pump body 1;

[0028] The water pump body 1 is equipped with a filter assembly 2 at its inlet. The filter assembly 2 includes a connecting pipe 201 fixedly connected to the water inlet of the water pump body 1. A fixed housing 202 is fixedly connected to one end of the connecting pipe 201 away from the water pump body 1. A mesh cover 203 is fixedly connected to the side of the fixed housing 202 away from the connecting pipe 201. Mounting housings 204 are symmetrically fixedly connected to the outside of the fixed housing 202. A waterproof motor 205 is fixedly connected to the outside of one of the mounting housings 204. The connecting pipe 201 is connected to the water pump body 1 through a flange and is long enough to allow the fixed housing 202 to be submerged in water.

[0029] The mounting shell 204 has a first gear 206 and a second gear 207 rotatably mounted inside. The surface edge of the second gear 207 is fixedly connected to a rocker column 208. The middle of the fixed shell 202 is rotatably connected to a connecting shaft 209. The two ends of the connecting shaft 209 extend out of the mounting shell 204 and are fixedly connected to the same arc rod 212. The inner side of the arc rod 212 is fixedly connected to a hanging knife 213, which fits against the outer side of the mesh cover 203. The sliding of the rocker column 208 and the transverse groove 211 causes the rocker plate 210 to swing repeatedly within a range of 170 degrees, realizing the reciprocating swing of the arc rod 212, thereby cleaning the mesh cover 203. Furthermore, the mesh cover 203 has a spherical shape, making it difficult for garbage such as plastic bags to adhere stably to the outer side of the mesh cover 203 under water flow.

[0030] Among them, the connecting shaft 209 is externally fixedly connected to a section inside the mounting shell 204, and a horizontal groove 211 is provided in the middle of the rocker plate 210. The internal cleaning component 3 is provided inside the fixed shell 202.

[0031] The output end of the waterproof motor 205 extends into the mounting housing 204 and is fixedly connected to the first gear 206, and the rocker column 208 is slidably connected to the transverse groove 211.

[0032] The connecting shaft 209 is located at the center of the mesh cover 203, and the first gear 206 and the second gear 207 are meshed and connected.

[0033] Both the first gear 206 and the second gear 207 are rotatably connected to the mounting housing 204.

[0034] The internal cleaning component 3 includes a fixing cover 301 sleeved on the outside of the connecting shaft 209, and both ends of the fixing cover 301 are fixedly connected to the inner wall of the fixing shell 202.

[0035] A first bevel gear 302 is fixedly connected to the outside of the connecting shaft 209, and a second bevel gear 303 is rotatably connected to the inside of the fixing cover 301. The first bevel gear 302 and the second bevel gear 303 are meshed together, and the fixing cover 301 is rotatably connected to the connecting shaft 209. The fixing cover 202 can protect the first bevel gear 302 and the second bevel gear 303 to prevent impurities and water from corroding them.

[0036] A connecting rod 304 is rotatably connected to the side of the fixed cover 301 near the mesh cover 203. One end of the connecting rod 304 is fixedly connected to the second bevel gear 303, and the other end of the connecting rod 304 is fixedly connected to a pair of arc-shaped scrapers 305. The arc-shaped scrapers 305 are in close contact with the inner side of the mesh cover 203. The arc-shaped scrapers 305 will scrape away the debris, which will be pumped away with the water flow to prevent it from gradually accumulating inside the mesh cover 203.

[0037] Working principle: Before using this type of water pump filtration device for water conservancy management, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5 As shown, after the water pump body 1 is placed in the water, the waterproof motor 205 is started, which causes the first gear 206 to drive the second gear 207 to rotate. During this process, the rocker column 208 will slide in the transverse groove 211, thereby causing the rocker plate 210 to swing down 90 degrees, then up 170 degrees, and then down 170 degrees, forming a reciprocating swing. The rocker plate 210 will drive the connecting shaft 209 to rotate during the swing, thereby driving the arc rod 212 to move. The hanging knife 213 will move to fit the outside of the mesh cover 203. During this process, the hanging knife 213 will scrape away the garbage and waste attached to the outside of the mesh cover 203.

[0038] Furthermore, when the connecting shaft 209 rotates, the first bevel gear 302 can drive the second bevel gear 303 to rotate, thereby causing the connecting rod 304 to rotate. The rotation of the connecting rod 304 can drive the arc-shaped scraper 305 to move against the inner wall of the mesh cover 203. When some silt and impurities pass through the mesh cover 203 and enter the inner side of the mesh cover 203 due to the squeezing of the scraper 213, the arc-shaped scraper 305 will scrape them off and pump them away with the water flow, preventing them from gradually accumulating inside the mesh cover 203.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
