DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] In actual use of an existing anti-clogging energy-saving water pump, water plants and debris are blocked in the through holes on the outer shell. If the first blade and the second blade want to break the weeds and debris more thoroughly, they need to be close to the outer wall of the outer shell, but this will cause the blades to scratch the outer wall of the outer shell when rotating, accelerating the wear of the blades. If the blades do not contact the outer shell, the water plants and debris blocking the through holes cannot be cleaned, and only the water plants and impurities at a certain distance from the through holes can be cleaned, which affects the water pumping efficiency of the water pump. Therefore, a cleaning component that can both break impurities and have a cleaning effect is provided to solve the above problem. Example

[0030] like Figures 1 to 4The utility model provides an anti-clogging energy-saving water pump.

[0031] Specifically, by Figure 1-Figure 3 A blockage-proof energy-saving water pump is provided, comprising a water pump body 1, a water guide pipe 3, an outer filter screen 9, an inner filter screen 10, a cylindrical fixing block 12 and a cleaning component 2, wherein the water pump body 1 is connected to the outer filter screen 9 through the cylindrical fixing block 12, and the cleaning component 2 is used to clean the inner wall of the outer filter screen 9 and the outer wall of the inner filter screen 10, and the cleaning component 2 comprises a servo motor 201 arranged inside the outer filter screen 9, a driving end of the servo motor 201 is connected to a fixing rod 202, and an end of the fixing rod 202 away from the servo motor 201 is fixedly installed with a connecting rod Rod 203, the outer wall of the connecting rod 203 is rotatably connected to two support rods 204, the outer wall of the support rod 204 is connected to an L-shaped scraper rod 205, the end of the L-shaped scraper rod 205 away from the support rod 204 is close to the cylindrical fixed block 12, and a plurality of blades 206 are fixedly installed on the outer wall of the support rod 204, and the blades 206 are located between the L-shaped scraper rod 205 and the inner filter screen 10, and a gear ring 207 is installed on the outer wall of the cylindrical fixed block 12, and a gear 208 meshing with the gear ring 207 is installed on the end of the support rod 204 away from the connecting rod 203.

[0032] When the water pump body 1 draws water from the river, the water first enters the interior of the water pipe 3 and then enters the water pump body 1. In order to prevent the water plants and impurities in the river from entering the interior of the water pump body 1 through the water pipe 3, the water plants and impurities are separated from the water flow by the outer filter screen 9 and the inner filter screen 10. However, some impurities and water plants will be blocked in the pores of the outer filter screen 9 or enter the interior of the outer filter screen 9.

[0033] Therefore, firstly, the servo motor 201 drives the fixed rod 202 and the connecting rod 203 to rotate, and the rotating connecting rod 203 drives the two supporting rods 204 and the L-shaped scraper rod 205 to perform a circular motion with the fixed rod 202 as the center point. When the L-shaped scraper rod 205 rotates, it rubs against the inner wall of the outer filter screen 9, thereby scraping off the impurities and water plants blocked in the pores of the outer filter screen 9. Then, the gear 208 meshing with the gear ring 207 rotates itself while following the circular motion of the supporting rod 204, thereby driving the L-shaped scraper rod 205 to rotate.

[0034] When the support rod 204 rotates, it drives the multiple blades 206 to rotate, and the rotating blades 206 break the impurities and water plants, preventing the larger impurities and water plants from blocking the pores of the inner filter screen 10, and also preventing the longer water plants from winding around the outer wall of the inner filter screen 10 and affecting the water flow. The rotating support rod 204 drives the L-shaped scraper 205 to perform a circular motion with the support rod 204 as the center point.

[0035] The rotating L-shaped scraper 205 will scrape the outer wall of the inner filter 10, so that the L-shaped scraper 205 can clean the outer wall of the inner filter 10 while cleaning the inner wall of the outer filter 9, avoiding impurities from being blocked in the pores of the inner filter 10 and reducing the amount of impurities entering the water pump body 1. A 5 cm gap is left between the blade 206 and the L-shaped scraper 205 and the inner filter 10, so that the L-shaped scraper 205 will not rub against the L-shaped scraper 205 and the inner filter 10 during rotation, avoiding wear of the blade 206, and also enabling the blade 206 to fully crush the impurities and aquatic plants between the inner filter 10 and the outer filter 9, avoiding leaving too many unbroken impurities.

[0036] Further:

[0037] like Figure 2 It is shown that the support rod 204 and the blade 206 are located between the L-shaped scraper rod 205 and the inner filter screen 10, and there are gaps between the blade 206 and the L-shaped scraper rod 205 and the outer wall of the inner filter screen 10. The distance between the blade 206 and the L-shaped scraper rod 205, and the distance between the blade 206 and the inner filter screen 10 are both 5 cm. The L-shaped scraper rod 205 touches the inner wall of the outer filter screen 9 and the outer wall of the inner filter screen 10.

[0038] A gap of 5 cm is left between the blade 206 and the L-shaped scraper 205 and the inner filter 10, so that the L-shaped scraper 205 will not rub against the L-shaped scraper 205 and the inner filter 10 during rotation, thereby avoiding wear of the blade 206. At the same time, the blade 206 can also fully crush the impurities and aquatic plants between the inner filter 10 and the outer filter 9.

[0039] Further:

[0040] like Figure 2 It is shown that a circular baffle 11 is installed on the inner wall of the outer filter screen 9, a fixing rod 202 is rotatably connected to the circular baffle 11, a servo motor 201 is installed on the outer wall of the circular baffle 11, and the outer filter screen 9 is fixedly installed on the outer wall of a cylindrical fixing block 12.

[0041] The circular baffle 11 separates the servo motor 201 from the connecting rod 203. When water flow and impurities enter the interior of the outer filter screen 9, the water flow will not impact the servo motor 201, so as not to affect the use of the servo motor 201. The servo motor 201 is installed on the outer wall of the servo motor 201 to provide support for the servo motor 201, making the servo motor 201 more stable when in use. The outer filter screen 9 is installed on the outer wall of the cylindrical fixing block 12, so that the outer filter screen 9 is not easy to fall off.

[0042] like Figure 2-Figure 3It is shown that the water pipe 3 is located inside the cylindrical fixed block 12 and is connected between the water pump body 1 and the outer filter screen 9. A circular filter screen 13 is installed at one end of the water pipe 3 extending to the inside of the outer filter screen 9. A mounting rod 14 is installed on the outer wall of the connecting rod 203. A scraper 16 is installed at one end of the mounting rod 14 away from the connecting rod 203. The scraper 16 is against the outer wall of the circular filter screen 13. Two support rods 15 are fixedly installed between the scraper 16 and the connecting rod 203. The outer wall of the support rod 15 touches the inner wall of the inner filter screen 10.

[0043] When the water flows into the inner filter screen 10, most of the impurities will be blocked by the inner filter screen 10, but a small part of smaller impurities will still enter the inner filter screen 10. The cylindrical fixing block 12 can further filter these impurities. When the mounting rod 14 rotates following the connecting rod 203, it will drive the scraper 16 to rotate. The scraper 16 cleans the outer wall of the circular filter screen 13, which can effectively prevent impurities from accumulating in the pores of the circular filter screen 13. At the same time, when the support rod 15 rotates following the connecting rod 203, it cleans the inner wall of the inner filter screen 10, and cooperates with the L-shaped scraper rod 205 to clean the inner filter screen 10, thereby improving the dredging effect of the inner filter screen 10.

[0044] Further:

[0045] like Figure 2 and Figure 4 It is shown that a circular slide groove 17 is provided on the outer wall of the cylindrical fixed block 12, and the circular slide groove 17 is located inside the outer filter screen 9. The end of the L-shaped scraper rod 205 away from the support rod 204 is connected to a ball 18, and the ball 18 is located inside the circular slide groove 17 and is slidingly connected to the inner wall of the circular slide groove 17. The circular slide groove 17 is located between the outer filter screen 9 and the gear ring 207.

[0046] When the L-shaped scraper rod 205 rotates, the sliding of the ball 18 and the circular groove 17 reduces the friction between the L-shaped scraper rod 205 and the cylindrical fixing block 12, reduces the wear of the L-shaped scraper rod 205 and the cylindrical fixing block 12, and also makes the L-shaped scraper rod 205 rotate more smoothly and stably.

[0047] like Figure 3 It is shown that the water pump body 1 is connected with a cylindrical block 4, the inner wall of the cylindrical block 4 is connected with a mesh frame 5, the mesh frame 5 is located between the water pipe 3 and the water pump body 1, the mesh frame 5 extends to one end of the cylindrical block 4 and is fixedly installed with a connecting block 8, the connecting block 8 extends to one side of the cylindrical block 4 and is installed with a pull rod 7, activated carbon 6 is connected between the connecting block 8 and the mesh frame 5, and the activated carbon 6 is located inside the mesh frame 5 and the connecting block 8.

[0048] Water flows into the water pump body 1 through the water pipe 3, and impurities in the water are adsorbed by the activated carbon 6 at the connection between the water pipe 3 and the water pump body 1, which further reduces the entry of impurities. The mesh frame 5 allows water to enter the interior of the mesh frame 5, which is convenient for the activated carbon 6 to adsorb impurities. When replacement is required, it is only necessary to pull the pull rod 7 to pull out the mesh frame 5 and the activated carbon 6 through the connecting block 8. The connecting block 8 blocks the gap opened in the cylindrical block 4 for the mesh frame 5 to slide, thereby preventing water from entering the cylindrical fixed block 12 from the gap opened in the cylindrical block 4.

[0049] Working principle:

[0050] When the water pump body 1 draws water from the river, the water first enters the interior of the water pipe 3 and then enters the water pump body 1. In order to prevent the water plants and impurities in the river from entering the interior of the water pump body 1 through the water pipe 3, the water plants and impurities are separated from the water flow by the outer filter screen 9 and the inner filter screen 10. However, some impurities and water plants will be blocked in the pores of the outer filter screen 9 or enter the interior of the outer filter screen 9.

[0051] Therefore, firstly, the servo motor 201 drives the fixed rod 202 and the connecting rod 203 to rotate, and the rotating connecting rod 203 drives the two supporting rods 204 and the L-shaped scraper rod 205 to perform a circular motion with the fixed rod 202 as the center point. When the L-shaped scraper rod 205 rotates, it rubs against the inner wall of the outer filter screen 9, thereby scraping off the impurities and water plants blocked in the pores of the outer filter screen 9. Then, the gear 208 meshing with the gear ring 207 rotates itself while following the circular motion of the supporting rod 204, thereby driving the L-shaped scraper rod 205 to rotate.

[0052] When the support rod 204 rotates, it drives the multiple blades 206 to rotate, and the rotating blades 206 break the impurities and water plants, preventing the larger impurities and water plants from blocking the pores of the inner filter screen 10, and also preventing the longer water plants from winding around the outer wall of the inner filter screen 10 and affecting the water flow. The rotating support rod 204 drives the L-shaped scraper 205 to perform a circular motion with the support rod 204 as the center point.

[0053] The rotating L-shaped scraper 205 will scrape the outer wall of the inner filter 10, so that the L-shaped scraper 205 can clean the outer wall of the inner filter 10 while cleaning the inner wall of the outer filter 9, avoiding impurities from being blocked in the pores of the inner filter 10 and reducing the amount of impurities entering the water pump body 1. A 5 cm gap is left between the blade 206 and the L-shaped scraper 205 and the inner filter 10, so that the L-shaped scraper 205 will not rub against the L-shaped scraper 205 and the inner filter 10 during rotation, avoiding wear of the blade 206, and also enabling the blade 206 to fully crush the impurities and aquatic plants between the inner filter 10 and the outer filter 9, avoiding leaving too many unbroken impurities.

[0054] Water flows into the water pump body 1 through the water pipe 3, and impurities in the water are adsorbed by the activated carbon 6 at the connection between the water pipe 3 and the water pump body 1, which further reduces the entry of impurities. The mesh frame 5 allows water to enter the interior of the mesh frame 5, which is convenient for the activated carbon 6 to adsorb impurities. When replacement is required, it is only necessary to pull the pull rod 7 to pull out the mesh frame 5 and the activated carbon 6 through the connecting block 8. The connecting block 8 blocks the gap opened in the cylindrical block 4 for the mesh frame 5 to slide, thereby preventing water from entering the cylindrical fixed block 12 from the gap opened in the cylindrical block 4.

[0055] The above is only a preferred embodiment of the present invention, and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the present invention.
