Description

Technical Field

[0001] This application relates to the field of submersible pump technology, and in particular to a stable submersible pump. Background Technology

[0002] Submersible pumps are important equipment for lifting water and are commonly used in deep wells, canals, reservoirs and other similar applications. Submersible pumps need to be submerged in water. The impeller inside the submersible pump rotates, driving the liquid around the pump through a filtration mechanism before it enters the pump. The liquid then flows through the pump into a water delivery pipe connected to the pump's outlet.

[0003] The water body to be pumped usually contains uneven sediment and other impurities. In the existing technology, the filtration mechanism is usually located below the submersible pump body to filter impurities and support the pump body. The bottom of the filtration mechanism is usually a flat structure, which makes it easy for the submersible pump to tip over after it is submerged in the water body due to insufficient contact between the bottom and the sediment, thus affecting the water pumping efficiency. Utility Model Content

[0004] This application provides a more stable submersible pump.

[0005] The stable submersible pump provided in this application adopts the following technical solution:

[0006] A stable submersible pump includes a pump body, a filter element, and a mounting base connected sequentially from top to bottom. The mounting base has multiple first mounting holes and multiple second mounting holes on the side facing away from the filter element. A first push rod is installed in the first mounting hole and is driven by a suction cup. A second push rod is installed in the second mounting hole and is driven by a first support rod.

[0007] Preferably, the first mounting hole includes a large-diameter hole and a small-diameter hole, the large-diameter hole being opened at the end of the mounting base facing away from the filter element, and the small-diameter hole being located at the end of the large-diameter hole closer to the filter element;

[0008] The first push rod is installed in the small-diameter hole and driven to the suction cup in the direction from the small-diameter hole to the large-diameter hole. The length of the first push rod is the same as the depth of the small-diameter hole, and the length of the suction cup is the same as the depth of the large-diameter hole.

[0009] Preferably, the depth of the second mounting hole is not less than the sum of the lengths of the second push rod and the first support rod along the first support rod.

[0010] Preferably, the filter element includes a first filter section and a second filter section, the first filter section and the second filter section are coaxially arranged, the second filter section is connected to the pump body, the first filter section is connected to the side of the second filter section opposite to the pump body, the first filter section has a first filter hole, the second filter section has a second filter hole, and the diameter of the first filter hole is larger than the diameter of the second filter hole.

[0011] Preferably, the mounting base is an annular structure and is connected to the bottom of the cylindrical structure. The mounting base is provided with multiple water inlets, which penetrate the mounting base along the outer circumference to the inner circumference of the annular structure.

[0012] Preferably, the pump body is provided with a third push rod, and the third push rod is driven to connect to a second support rod.

[0013] In summary, this application includes at least one of the following beneficial technical effects:

[0014] 1. By setting a first push rod driven to be connected to a suction cup and a second push rod driven to be connected to a first support rod, the stable submersible pump of this application can brake the first push rod or the second push rod according to different application scenarios, and selectively choose the connection method with the bottom of the water body. Compared with the prior art, the stable submersible pump of this application can be placed more stably in the water body.

[0016] 3. By setting the depth of the second mounting hole to be no less than the sum of the lengths of the second push rod and the first support rod along the first support rod, the first support rod of the stability submersible pump of this application is housed in the second mounting hole when not in operation, making it less prone to impact and increasing the service life of the second support rod.

[0022] The present application will be further described in detail below with reference to the accompanying drawings.

[0023] This application provides a stable submersible pump, such as Figures 1 to 4 As shown, the device includes a pump body 1, a filter element 2, and a mounting base 3 connected sequentially from top to bottom. The mounting base 3 has multiple first mounting holes 31 and multiple second mounting holes 32 on the side facing away from the filter element 2. A first push rod 4 is installed in the first mounting hole 31, and a suction cup 5 is driven and connected to the first push rod 4. A second push rod 6 is installed in the second mounting hole 32, and a first support rod 7 is driven and connected to the second push rod 6.

[0024] In the use of the stabilized submersible pump of this application, the first push rod 4 or the second push rod 6 can be driven according to the amount of sediment in the water. Specifically, when the application scenario is a swimming pool or other situation without large sediment, the first push rod 4 can be braked first, causing the first push rod 4 to push out the suction cup 5. After submerging, the suction cup 5 will adhere to the bottom of the pool to achieve stability. When the application scenario is a pool with sediment, the second push rod 6 can be braked before submerging into the water, causing the second push rod 6 to push out the first support rod 7. As the stabilized submersible pump submerges, the first support rod 7 will insert into the sediment, thereby achieving stability.

[0025] This application discloses a stable submersible pump. By setting a first push rod 4 to be driven and connected to a suction cup 5, and a second push rod 6 to be driven and connected to a first support rod 7, the stable submersible pump of this application can brake the first push rod 4 or the second push rod 6 according to different application scenarios, and selectively choose the connection method with the bottom of the water body. Compared with the prior art, the stable submersible pump of this application can be placed more stably in the water body.

[0026] Each first push rod 4 is connected to a plurality of first support rods 7, and the plurality of first support rods 7 are connected to the end of the first push rod 4 facing away from the filter element 2.

[0027] The first mounting hole 31 includes a large-diameter hole 311 and a small-diameter hole 312. The large-diameter hole 311 is located at the end of the mounting base 3 facing away from the filter element 2, and the small-diameter hole 312 is located at the end of the large-diameter hole 311 close to the filter element 2. The first push rod 4 is installed in the small-diameter hole 312 and is driven and connected to the suction cup 5 along the direction from the small-diameter hole 312 to the large-diameter hole 311. The length of the first push rod 4 is the same as the depth of the small-diameter hole 312, and the length of the suction cup 5 is the same as the depth of the large-diameter hole 311. Specifically, the first mounting... Hole 31 is a stepped hole, and the cross-sectional dimension of the large-diameter hole 311 is not less than the maximum cross-sectional dimension of the suction cup 5. When not in operation, the suction cup 5 is located inside the large-diameter hole 311, and the end of the suction cup 5 facing away from the small-diameter hole 312 is flush with the end of the large-diameter hole 311 facing away from the small-diameter hole 312. When in operation, the first push rod 4 drives the suction cup 5 away from the large-diameter hole 311. In this way, when the stability submersible pump of this application is not in operation, the suction cup 5 is stored inside the large-diameter hole 311, which is not easy to be bumped and increases the service life of the suction cup 5.

[0028] The depth of the second mounting hole 32 is not less than the sum of the lengths of the second push rod 6 and the first support rod 7 along the first support rod 7. Specifically, the depth of the second mounting hole 32 is equal to the sum of the lengths of the second push rod 6 and the first support rod 7 along the first support rod 7. When not in operation, the second push rod 6 and the first support rod 7 are located inside the second mounting hole 32, with the end of the first support rod 7 facing away from the second push rod 6 flush with the opening of the second mounting hole 32. When in operation, the second push rod 6 drives the first support rod 7 away from the second mounting hole 32. Thus, when the stability submersible pump of this application is not in operation, the first support rod 7 is housed inside the second mounting hole 32, making it less prone to impact and increasing the service life of the second support rod 9.

[0029] The filter element 2 includes a first filter section 21 and a second filter section 22, which are coaxially arranged. The second filter section 22 is connected to the pump body 1, and the first filter section 21 is connected to the side of the second filter section 22 facing away from the pump body 1. The first filter section 21 has a first filter hole 211, and the second filter section 22 has a second filter hole 221. The diameter of the first filter hole 211 is larger than the diameter of the second filter hole 221. Specifically, the first filter section 21 is a cylindrical first filter barrel, and the second filter section 22 is a circular second filter plate. The second filter plate is connected to the pump body 1. The opening of the first filter barrel is fixed to the side of the second filter plate facing away from the pump body 1 by bolts. The first filter holes 211 are distributed in the barrel body and bottom of the first filter barrel, and the second filter holes 221 are distributed in the second filter plate. During operation, the liquid first passes through the first filter barrel to filter out large-volume impurities, and then the second filter plate filters out small-volume impurities. This improves the filtration effect of the stable submersible pump of this application and reduces the impurities entering the pump body 1.

[0030] The mounting base 3 is a ring-shaped structure and is connected to the bottom of the cylindrical structure. The mounting base 3 is provided with multiple water inlets 33. The water inlets 33 penetrate the mounting base 3 along the outer circumference to the inner circumference of the ring-shaped structure. Specifically, the edges of the water inlets 33 are set with rounded corners. During operation, the liquid passes through the water inlets 33 and then passes through the first filter hole 211 at the bottom of the first filter bucket for filtration. This improves the efficiency of water lifting and filtration.

[0031] The pump body 1 is provided with a third push rod 8, which is driven and connected to a second support rod 9. Specifically, the pump body 1 is provided with multiple third push rods 8, and each of the multiple third push rods 8 is driven and connected to a second support rod 9. During operation, the third push rod 8 is braked, causing the third push rod 8 to drive the second support rod 9 to insert into the soil. In this way, the stability of the stable submersible pump of this application is strengthened.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
