Description

Technical Field

[0001] This utility model relates to the field of submersible pump technology, and in particular to a submersible pump for timed backflushing and cleaning of the inlet. Background Technology

[0002] A submersible pump is a fluid transport device that integrates the pump body and drive motor into one unit and can operate submerged in liquid. It is widely used in agricultural irrigation, municipal drainage, industrial wastewater treatment, deep well water intake, and other scenarios. Its core structure typically includes an inlet section, impeller, pump casing, submersible motor, and sealing components. The motor drives the impeller to rotate at high speed, generating centrifugal force or thrust, which draws liquid in from the inlet and transports it to the target location through the outlet pipe. It features a compact structure, convenient installation, and a wide head range. In existing technologies, the inlet of a submersible pump is a crucial channel for liquid to enter the pump body, and its unobstructed flow directly affects the operating efficiency and reliability of the equipment. However, in practical applications, the inlet is prone to blockage due to the intake of solid impurities (such as silt, aquatic plants, fibrous debris, etc.) in the water. On the one hand, the accumulation of impurities in the inlet or flow channel reduces the flow area, increases the water inlet resistance, and causes a decrease in pump flow and an increase in energy consumption. On the other hand, severe blockage may lead to malfunctions such as jamming and motor overload, shortening the service life of the equipment and even requiring frequent shutdowns for cleaning and maintenance, increasing operation and maintenance costs and operational risks. This problem is particularly prominent in complex working conditions with a high content of impurities. Therefore, this utility model proposes a submersible pump with a timed backflushing cleaning of the inlet to solve the problems existing in the prior art. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a submersible pump for timed backflushing and cleaning the inlet. This submersible pump takes in water through an inlet nozzle and an inlet channel, and drains water through an outlet nozzle. A flushing chamber is located under the pump body, connected to a clean water source via a clean water pipe. A second motor drives a drive gear to rotate, which, in conjunction with a driven gear, generates pump power, causing clean water to flush towards the inlet channel. During this process, an opening and closing component closes the inlet, thereby flushing and cleaning the inlet channel, preventing blockages, and ensuring the normal operation of the device.

[0004] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a submersible pump for timed backflushing and cleaning of the inlet, including a pump body, an inlet nozzle and an outlet nozzle. The inlet nozzle is located on one side of the bottom of the pump body, and the outlet nozzle is located on one side of the pump body. A water inlet channel connected to the inlet nozzle is provided at the lower part of the pump body. A flushing chamber is provided on one side of the lower part of the pump body. A driving gear and a driven gear that are adapted to each other are rotatably provided inside the flushing chamber. The driving gear is started at a time. The output end of the flushing chamber faces the water inlet channel, and the input end of the flushing chamber is connected to a clean water pipe. A timed solenoid valve is provided on the clean water pipe. The pump body has a water outlet chamber on one side that is connected to the water outlet nozzle, and there is a passage between the water outlet chamber and the water inlet channel. The passage is equipped with a timed start-up and stop component.

[0005] A further improvement is that the opening and closing assembly includes a rotating roller and a closing door. The rotating roller is rotatably located below the opening, and the closing door is connected to the rotating roller and is adapted to the opening.

[0006] A further improvement is that a guide block is provided on one side of the lower part of the opening, and the guide block is inclined, and the guide block is adapted to the closing door.

[0007] A further improvement is that the front end of the pump body is provided with a first motor and a second motor, the first motor being connected to the rotating roller and the second motor being connected to the drive gear.

[0008] A further improvement is that the control terminals of the first motor, the second motor, and the solenoid valve are all connected to wires, and the wires are electrically connected to the timing controller.

[0009] A further improvement is that a top chamber is provided on one side of the top of the pump body, and a rotating shaft is provided inside the top chamber. A connecting piece is provided between the pump body and the top chamber. The lower end of the rotating shaft passes through the connecting piece and is provided with an impeller. The impeller is located above the water inlet channel.

[0010] A further improvement is that a bearing and a bushing are provided between the upper part of the outer side of the rotating shaft and the top chamber, and a mechanical seal is provided between the lower part of the outer side of the rotating shaft and the connecting piece.

[0011] The beneficial effects of this utility model are as follows: 1. This utility model allows water to enter through an inlet nozzle and an inlet channel, and to exit through an outlet nozzle. A flushing chamber is set under the pump body, and a clean water source is connected through a clean water pipe. A second motor drives the active gear to rotate, which in turn works with the driven gear to generate pump power, so that clean water is flushed towards the inlet channel. During this process, the opening is closed by the opening and closing component, thereby flushing and cleaning the inlet channel, avoiding blockage, and ensuring the normal operation of the device.

[0012] 2. In this utility model, the first motor, the second motor, and the solenoid valve are all electrically connected to the timer controller via wires. When not in use, the opening and closing components are open and the solenoid valve is closed. When the submersible pump stops running, the timer controller starts the first motor, the second motor, and the solenoid valve at regular intervals, closes the opening and closing components, drives the drive gear to run, and opens the solenoid valve, thereby achieving the purpose of timed cleaning, making it more convenient to use.

[0015] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0016] Example 1 according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a submersible pump for timed backflushing and cleaning of the water inlet, including a pump body 1, a water inlet 2, and a water outlet 3. The water inlet 2 is located on one side of the bottom of the pump body 1, and the water outlet 3 is located on one side of the pump body 1. A water inlet channel 4 connected to the water inlet 2 is provided in the lower part of the pump body 1. A flushing chamber 5 is provided in one side of the lower part of the pump body 1, and a driving gear 6 and a driven gear 7 are rotatably arranged inside the flushing chamber 5. The driving gear 6 is activated at timed intervals. The output end of the flushing chamber 5 faces the water inlet channel 4, and a clean water pipe 8 is connected to the input end of the flushing chamber 5. A timed solenoid valve 9 is provided on the clean water pipe 8. The pump body 1 has a water outlet chamber connected to the water outlet 3 on one side, and a passage 10 is provided between the water outlet chamber and the water inlet channel 4. The passage 10 is equipped with a timed opening and closing component. In use, water enters through the water inlet 2 and the water inlet channel 4, and water is discharged through the water outlet 3. A flushing chamber 5 is set under the pump body 1, and a clean water source is connected through a clean water pipe 8. The second motor 14 drives the drive gear 6 to rotate, which works in conjunction with the driven gear 7 to generate pump power, so that the clean water is flushed towards the water inlet channel 4. During this process, the opening and closing component closes the passage 10, thereby flushing and cleaning the water inlet channel 4, preventing blockage, and ensuring the normal operation of the device.

[0017] The opening and closing assembly includes a rotating roller 11 and a closing door 12. The rotating roller 11 is rotatably disposed below the opening 10, and the closing door 12 is connected to the rotating roller 11 and is adapted to the opening 10. In use, the first motor 13 causes the rotating roller 11 to rotate, which in turn causes the closing door 12 to rotate, facilitating the opening or closing of the opening 10.

[0018] A guide block 17 is provided on one side of the lower part of the opening 10, and the guide block 17 is inclined. The guide block 17 is adapted to the closing door 12. During the opening of the closing door 12, one end of the closing door 12 is adapted to the guide block 17. Water is guided by the inclined surface of the guide block 17, which avoids the impact of the pump body 1 on the closing door 12 during normal operation and improves its service life.

[0019] The pump body 1 has a first motor 13 and a second motor 14 at its front end. The first motor 13 is connected to the rotating roller 11, and the second motor 14 is connected to the drive gear 6. The control terminals of the first motor 13, the second motor 14, and the solenoid valve 9 are all connected to wires 15, which are electrically connected to a timer controller 16. When not in use, the opening and closing assembly is open, and the solenoid valve 9 is closed. When the submersible pump stops running, the timer controller 16 periodically starts the first motor 13, the second motor 14, and the solenoid valve 9, closes the opening and closing assembly, drives the drive gear 6, and opens the solenoid valve 9, thereby achieving timed cleaning and making it more convenient to use.

[0020] Example 2 according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a submersible pump for timed backflushing and cleaning of the water inlet, including a pump body 1, a water inlet 2, and a water outlet 3. The water inlet 2 is located on one side of the bottom of the pump body 1, and the water outlet 3 is located on one side of the pump body 1. A water inlet channel 4 connected to the water inlet 2 is provided in the lower part of the pump body 1. A flushing chamber 5 is provided in one side of the lower part of the pump body 1, and a driving gear 6 and a driven gear 7 are rotatably arranged inside the flushing chamber 5. The driving gear 6 is activated at timed intervals. The output end of the flushing chamber 5 faces the water inlet channel 4, and a clean water pipe 8 is connected to the input end of the flushing chamber 5. A timed solenoid valve 9 is provided on the clean water pipe 8. The pump body 1 has a water outlet chamber connected to the water outlet 3 on one side, and a passage 10 is provided between the water outlet chamber and the water inlet channel 4. The passage 10 is equipped with a timed opening and closing component. In use, water enters through the water inlet 2 and the water inlet channel 4, and water is discharged through the water outlet 3. A flushing chamber 5 is set under the pump body 1, and a clean water source is connected through a clean water pipe 8. The second motor 14 drives the drive gear 6 to rotate, which works in conjunction with the driven gear 7 to generate pump power, so that the clean water is flushed towards the water inlet channel 4. During this process, the opening and closing component closes the passage 10, thereby flushing and cleaning the water inlet channel 4, preventing blockage, and ensuring the normal operation of the device.

[0021] A top chamber 18 is provided on one side of the top of the pump body 1, and a rotating shaft 19 is rotatably mounted inside the top chamber 18. A connecting member 20 is provided between the pump body 1 and the top chamber 18. The lower end of the rotating shaft 19 passes through the connecting member 20 and is equipped with an impeller 21, which is located above the water inlet channel 4. A bearing 22 and a bushing 23 are provided between the upper outer side of the rotating shaft 19 and the top chamber 18, and a mechanical seal 24 is provided between the lower outer side of the rotating shaft 19 and the connecting member 20. In use, the upper end of the rotating shaft 19 is connected to a drive motor, which drives the rotating shaft 19 and the impeller 21 to rotate, so that water enters the water inlet 2 and the water inlet channel 4, and water exits the water outlet 3. The mechanical seal 24 ensures a tight seal and prevents water from entering the top chamber 18.

[0022] The submersible pump for timed backwashing and cleaning the inlet water inlet takes in water through the inlet nozzle 2 and the inlet channel 4, and drains water through the outlet nozzle 3. A flushing chamber 5 is set under the pump body 1, which is connected to a clean water source through a clean water pipe 8. The second motor 14 drives the drive gear 6 to rotate, which, in conjunction with the driven gear 7, generates pump power, causing clean water to flush towards the inlet channel 4. During this process, the opening 10 is closed by the opening and closing component, thereby flushing and cleaning the inlet channel 4, preventing blockage, and ensuring the normal operation of the device. The first motor 13, the second motor 14, and the solenoid valve 9 are all electrically connected to the timer controller 16 through the wire 15. When not in use, the opening and closing component is open and the solenoid valve 9 is closed. When the submersible pump stops running, the timer controller 16 periodically starts the first motor 13, the second motor 14, and the solenoid valve 9, closes the opening and closing component, drives the drive gear 6 to run, and opens the solenoid valve 9, thereby achieving the purpose of timed cleaning and making it more convenient to use.
