Description

Technical Field

[0001] The utility model relates to the technical field of submersible pumps, in particular to a submersible pump with a filter screen that can be quickly replaced. Background Art

[0002] Submersible pumps are important equipment for deep well water extraction. When in use, the entire unit submerges in the water to extract groundwater to the surface. It is used for domestic water, mine rescue, industrial cooling, farmland irrigation, seawater lifting, ship loading, and fountain landscape. Hot water submersible pumps are used for hot spring bathing, and can also be used to extract groundwater from deep wells, and can also be used in water extraction projects such as rivers, reservoirs, and canals. It is mainly used for farmland irrigation and water for people and livestock in mountainous areas. It can also be used for central air-conditioning cooling, heat pump units, cold pump units, cities, factories, railways, mines, and construction site drainage. After searching, a Chinese patent with authorization announcement number CN219062097U discloses a submersible pump that is easy to quickly replace the filter screen, including a pump body, a water block, a water inlet pipe, a sealing block, a filter plate, a sealing mechanism, a water outlet pipe, and a connecting mechanism. The pump body is fixedly connected with a water block, the water block is fixedly connected with a water inlet pipe, the water inlet pipe is fixedly connected with a sealing block, the inner part of the sealing block is clamped with a filter plate, the filter plate is in contact with the water inlet pipe, the water inlet pipe is provided with a sealing mechanism, and the water block is fixedly connected with a water outlet pipe. The utility model is provided with a storage block, a rotating handle and other components. By rotating the rotating handle, the screw rotates to drive the sealing plate to move. The sealing plate isolates the water under the filter plate to avoid excessive water pressure and the filter plate being difficult to disassemble. This solves the problem that the installation and disassembly of the filter screen in the prior art are relatively troublesome. At the same time, during maintenance, the filter screen is relatively troublesome to disassemble due to the water pressure problem.

[0003] However, during actual use of the submersible pump of this scheme, since the filter plate is clamped inside the sealing block, such a connection structure may become loose when exposed to high-pressure fluid. Once a gap appears between one side of the filter plate and the inner wall of the submersible pump, the gap will gradually increase due to the pressurization of the fluid until the filter plate loses its filtering function.

[0004] Therefore, we have made improvements to this and proposed a submersible pump that can quickly replace the filter. Utility Model Content

[0005] In order to solve the problem that the filtering facilities of the existing submersible pumps are prone to loosening after rapid installation, the utility model provides a submersible pump with a filter screen that can be quickly replaced.

[0006] The utility model is achieved in this way:

[0007] A submersible pump with a quickly replaceable filter comprises a submersible pump body, a lifting assembly being mounted on the bottom end of the submersible pump body, a filter assembly being arranged inside the lifting assembly, and the filter assembly being located directly below the submersible pump body, fixing mechanisms being respectively installed on both sides of the lifting assembly, the fixing mechanisms comprising a cylinder, an insertion shaft, a limit block, a spring and a pull plate, the interior of the cylinder being slidably connected to a limit block, one end of the limit block being inserted and connected to the insertion shaft, one end of the insertion shaft extending to the outside of the cylinder, and an outer wall of the submersible pump body being provided with a positioning hole which engages with the insertion shaft, a spring being mounted on the outer wall of the insertion shaft, and the spring being located inside the cylinder, a groove being provided on one side of the insertion shaft, and a pull plate being installed inside the groove.

[0008] Furthermore, the submersible pump body comprises a pump body, a water outlet and a water inlet, the water outlet is arranged on the outer wall of the pump body, and the water inlet is arranged at the bottom end of the pump body.

[0009] The beneficial effect of adopting the above further solution is that, through the arrangement of the water outlet and the water inlet, a position is provided for the pipe docking of the pump body.

[0010] Furthermore, one end of the water outlet is connected to an output pipe.

[0011] The beneficial effect of adopting the above further solution is that, through the connection of the output pipe, the water flow absorbed by the submersible pump body can be easily directed to a designated location.

[0012] Furthermore, the filter assembly includes a ring frame, a gasket and a mesh body, the ring frame is installed inside the gasket, the mesh body is installed inside the ring frame, and the ring frame is located inside the water inlet.

[0013] The beneficial effect of adopting the above further solution is that, through the positional relationship between the ring frame and the water inlet, it is convenient to improve the sealing of the connection between the net body and the submersible pump body.

[0014] Furthermore, the lifting assembly includes a circular frame, supporting feet and a plurality of inner supporting plates, the inner wall of the circular frame is connected to the plurality of inner supporting plates, and the top ends of the plurality of inner supporting plates are fitted with the bottom ends of the washers.

[0015] The beneficial effect of adopting the above further solution is that, through the lifting effect of the inner supporting plate on the circular frame, it is convenient for the lifting component to squeeze and fix the net component.

[0016] Furthermore, a support foot is installed at the bottom end of the circular frame.

[0017] The beneficial effect of adopting the above further solution is that, through the installation and use of the supporting feet, the bottom of the submersible pump body is kept suspended in the air, avoiding blockage of the net body.

[0018] Furthermore, a power cord is connected to the top of the submersible pump body.

[0019] The beneficial effect of adopting the above further solution is that it is convenient to connect the power of the submersible pump body through the connection of the power cord.

[0020] Furthermore, a liquid level sensor is electrically connected to one side of the submersible pump body, an output end of the liquid level sensor is electrically connected to a main controller, and the main controller is electrically connected to the submersible pump body and is controlled by the main controller.

[0021] The beneficial effect of adopting the above further solution is that, by connecting and using the liquid level sensor, it is convenient to monitor the water condition in which the submersible pump body is located in real time, thereby avoiding idling of the submersible pump body.

[0022] Furthermore, a handle is installed on the top of the submersible pump body.

[0023] The beneficial effect of adopting the above further solution is that, through the connection and use of the handle, the submersible pump body is more convenient to carry.

[0024] The beneficial effect of the utility model is that through the mutual cooperation of the lifting assembly, the filter assembly, the fixing mechanism and the positioning hole, the filter facility can be quickly replaced while being easily fastened to avoid loosening. The elastic effect of the spring on the limit block causes the limit block to drive the plug shaft to maintain an outward trend until one end of the plug shaft extends to the inside of the positioning hole, prompting the lifting assembly to be fixed to the bottom of the submersible pump body, and then the inner support plate in the lifting assembly lifts the filter assembly, so that the filter assembly is restricted to the bottom end of the submersible pump body, thereby effectively reducing the loosening condition. Secondly, by pulling the pull plate, the plug shaft is disengaged from the positioning hole, and the lifting assembly is disengaged from the bottom of the submersible pump body, thereby driving the filter assembly to be disassembled and completing the corresponding replacement work.
