Description

Technical Field

[0001] The utility model relates to the technical field of submersible pumps, in particular to an anti-sand check structure for a submersible pump. Background Technique

[0002] A submersible pump is an important device for lifting water from deep wells. When in use, the whole unit is submerged in water to extract groundwater to the ground surface, and it is used for domestic water, mine rescue, industrial cooling, farmland irrigation, seawater lifting, ship ballasting, and can also be used for fountain landscapes.

[0003] In the comparative document "An Anti-sand Check Structure for a Submersible Pump" with the patent number (CN221322883U), a check plate inside the check cylinder is used to play a check role. The water flow impacts the check plate to move upward. The check plate drives the lifting ring plate to rise through a connecting rod. The lifting ring plate moves up and down along the semi-circular guide rod through the semi-circular notch to prevent the position of the check plate from shifting. When the check plate rises, the water outlet pipe is opened, and the water flow is normally pumped upward. When the work is finished, the check plate descends under the action of the gravity of the water, and the check plate presses on the upper part of the water outlet pipe for sealing to prevent the water from flowing back into the main body of the submersible pump, avoiding damage to the main body of the submersible pump and improving the service life of the main body of the submersible pump.

[0004] However, when the above structure is in use, it is externally installed outside the submersible pump, making the whole submersible pump overly bulky and inconvenient for users, and it can no longer meet the usage requirements of users. Summary of the Invention

[0020] In the manufacturing industry, equipment that needs to perform angle adjustment is often involved, such as the nozzle of an oxygen cutting machine, the nozzle of a laser cutting machine, the nozzle of automatic painting, and various equipment that needs to perform angle adjustment. The angle adjustment mechanisms in the prior art are either expensive or complex in structure, and there has never been an angle adjustment device that can meet the adjustment needs of users; to solve the above problems, an open-pit mine bench 65° slope blasting system is proposed. Embodiment

[0021] Please refer to Figures 1-4 For this utility model, a technical solution is provided: a sand-proof check valve structure for a submersible pump, which includes a pump body 1 and a sand-proof cover 2. The pump body 1 is used for pumping water, and the sand-proof cover 2 is used for sand prevention. A cavity is provided inside the sand-proof cover 2. A water outlet pipe 3 is connected to the bottom position on one side of the pump body 1. The water outlet pipe 3 can discharge water. A cavity is provided inside the water outlet pipe 3. Support vertical rods 4 are fixedly arranged at the front and rear ends of the inner top of the water outlet pipe 3. The support vertical rods 4 can play a supporting role. Guide grooves 5 are provided on the opposite sides of the two support vertical rods 4. The guide grooves 5 facilitate the sliding of the guide blocks 7. A sealing float ball 6 is arranged at the middle position inside the water outlet pipe 3. The sealing float ball 6 plays a role in sealing and preventing backwater. Guide blocks 7 are fixedly arranged on the front and rear surfaces of the sealing float ball 6. The guide blocks 7 can limit the sealing float ball 6. A filter plate 8 is fixedly arranged at the bottom position inside the sand-proof cover 2. The filter plate 8 can play a filtering role. A net column 9 is fixedly arranged at the bottom of the filter plate 8. The net column 9 is used to set alum 10. The inside of the net column 9 is filled with alum 10. The alum 10 can adsorb sediment.

[0022] Furthermore, the bottom of the pump body 1 is fixedly connected to the sand-proof cover 2. Among them, with this design, the two are connected together to play a good airtight role.

[0023] Furthermore, water inlet holes 11 are circumferentially provided on the outer surface of the sand-proof cover 2. Among them, the water inlet holes 11 play a role in water inlet.

[0024] Furthermore, the sealing float ball 6 is in contact with the inner wall of the water outlet pipe 3. Among them, the sealing float ball 6 can play a role in sealing and preventing backwater.

[0025] Furthermore, the opposite sides of the two guide blocks 7 extend into the inside of the guide grooves 5 and are in contact with the inner walls of the guide grooves 5. The guide blocks 7 are slidably connected to the guide grooves 5. Among them, the guide blocks 7 can limit the sealing float ball 6.

[0026] Furthermore, a return spring 12 is fixedly arranged at the top inside the guide groove 5. The bottom of the return spring 12 is fixedly connected to the guide block 7. Among them, the return spring 12 can drive the sealing float ball 6 to reset.

[0027] Furthermore, a water suction pipe is connected to the middle position at the bottom of the pump body 1, and the bottom of the water suction pipe penetrates through the sand-proof cover 2 and extends to its inside. Among them, the water suction pipe plays a role in water suction.

[0028] Working principle: When using this device, when the pump body 1 discharges water, the water outlet pressure will lift the sealed floating ball 6, so that the water can flow out smoothly. When there is no water discharge, the sealed floating ball 6 will be reset under the drive of the return spring 12, preventing the water from flowing back. Then, when pumping water, by setting alum 10, after alum 10 dissolves in water, aluminum ions will react with water to form aluminum hydroxide colloid, which has a large surface area and can adsorb sediment and suspended matter in the water, thus playing a role in preventing sand. Through the setting of the mesh column 9 and the filter plate 8, the water flow can be filtered again.

[0029] It can be known from the above working process that:

[0030] This sand-preventing and check-valve structure of the submersible pump, by setting the sealed floating ball 6, the filter plate 8, the mesh column 9 and the alum 10, makes the device adopt an internal hidden design when preventing sand and checking the valve. It can not only play the role of preventing sand and checking the valve, but also make the pump body 1 as a whole simple and beautiful, bringing convenience to the user, thus improving the practicability of this device and meeting the user's usage requirements.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
