Description

Technical Field

[0001] The invention belongs to the technical field of water pumps, and in particular relates to an energy-saving water pump with stable heat dissipation. Background Art

[0002] A water pump is a device used to pump water from a low place to a high place or push water to a relatively long distance. It is usually composed of a motor, a pump body and a hydraulic system. The water pump is driven by the motor to suck the liquid into the pump body and push the liquid to the target location through the force of the hydraulic system. Water pumps are widely used in water supply systems, drainage systems, cooling systems, air conditioning systems, and farmland irrigation.

[0003] The existing water pump installs a connecting pipe at the water outlet end of the pump body to facilitate the water discharged from the pump body to be introduced into the water outlet pipe on the top of the annular shell, and then the water outlet pipe is connected to the water supply pipeline. The water entering the water outlet pipe will flow into the spiral heat exchange tube, thereby facilitating heat exchange and cooling with the motor; the power of the water flowing discharged from the water outlet pipe is used to drive the rotating drum to rotate in conjunction with the hydraulic drive component, so that the fan blades rotate in the annular shell to form a flowing wind, and the wind guide component is used to blow the wind into the interior through the rear port of the motor, thereby further improving its heat dissipation efficiency.

[0004] Although the existing water pump uses the pumped water flow as the driving source to achieve the heat dissipation of the motor, it has a limitation. When the hydraulic drive component rotates in the outlet pipe, vortexes will be generated, and the fast-flowing discharge water flow interacts with this phenomenon, resulting in interference problems. This interference will hinder the normal operation of the hydraulic drive component, thereby affecting the effective air-cooling and heat dissipation effect of the motor. In addition, the heat dissipation structure design in the current water pump is only applicable to products of specific specifications, lacks sufficient flexibility, and is not convenient for application to water pumps of different models or sizes.

[0005] Therefore, in view of the above situation, it is urgent to develop an energy-saving water pump with stable heat dissipation to overcome the shortcomings in current practical applications. Summary of the invention

A moving part 437 that slides with its side wall is provided at the bottom of the adjusting wheel 435. One end of the moving part 437 extends into the connecting tube B422 and is connected to the sliding part 438. The outer wall of the sliding part 438 slides and fits with the inner wall of the connecting tube B422. A return spring A439 is installed between one end of the sliding part 438 and the inner wall of the connecting tube C423.

[0034] In this embodiment, the return spring A439 can help the moving part 437 to always slide against the side wall of the adjusting wheel 435 through its own elastic force, and the water source in the connecting pipe A411 can move the arc blade 432 by rapid flow, so that the arc blade 432 can drive the rotating wheel 431 to rotate, the rotating wheel 431 drives the rotating shaft 434 to rotate, and the rotating shaft 434 drives the adjusting wheel 435 to rotate.

Driven by the negative pressure, external water can enter the pump body 100 through the water inlet pipe, and the water inside the pump body 100 is discharged out of the pump body 100 through the water outlet pipe. At the same time, part of the water in the water inlet pipe can enter the connecting pipe A411, so as to ensure the stable heat dissipation of the cooling fins through the flow of water. There is no need to add additional driving sources and reduce dependence on external energy, thereby achieving stable heat dissipation and energy saving and efficiency improvement of the water pump. It is suitable for water pumps of various types and specifications and has strong versatility and flexibility.

[0039] In a preferred embodiment, one side of the T-shaped plate 550 is configured as an arc-shaped plate structure to increase the contact area between the T-shaped plate 550 and the inner wall of the pump body 100, thereby ensuring the stability of the negative pressure area and improving the pumping performance of the water pump.

[0040] The working principle of the present invention is: The water pump motor 300 drives the main shaft 600 to rotate, and the main shaft 600 drives the rotating block 510 to rotate eccentrically in the pump body 100. The rotating block 510 drives the slider 530 and the T-type dial plate 550 to rotate eccentrically. The return spring B540 can drive the slider 530 to slide back and forth in the installation groove 520 through its own elastic force, so that the T-type dial plate 550 can always fit with the inner wall of the pump body 100 during the eccentric rotation process, so that the T-type dial plate 550 can form a crescent-shaped negative pressure area in the pump body 100 during the eccentric rotation of the pump body 100. Driven by the negative pressure, the external water source can enter the pump body 100 through the water inlet pipe, and the water source inside the pump body 100 is discharged out of the pump body 100 through the water outlet pipe; At the same time, the negative pressure inside the pump body 100 can also allow part of the water source in the water inlet pipe to enter the connecting pipe A411. The water source in the connecting pipe A411 can move the arc blade 432 by rapid flow, so that the arc blade 432 can drive the rotating wheel 431 to rotate, the rotating wheel 431 drives the rotating shaft 434 to rotate, and the rotating shaft 434 drives the adjusting wheel 435 to rotate. The adjusting wheel 435 can drive the moving part 437 to move back and forth by cooperating with the groove 436 and the reset spring A439. The moving part 437 drives the sliding part 438 to slide back and forth in the connecting pipe B422. The reset spring A439 can help the moving part 437 to always slide against the side wall of the adjusting wheel 435 through its own elastic force. When the sliding member 438 slides in the connecting pipe B422 in a direction close to the moving member 437, the space surrounded by the sliding member 438, the connecting pipe B422, the connecting pipe C423 and the exhaust and suction pipe 424 becomes larger and forms a negative pressure area, so that external gas can enter the space, thereby realizing the exhaust function of the exhaust and suction pipe 424; when the sliding member 438 slides in the connecting member B in a direction away from the moving member 437, the space surrounded by the sliding member 438, the connecting pipe B422, the connecting pipe C423 and the exhaust and suction pipe 424 shrinks and forms a high pressure area, so that the gas in the space can be discharged from the exhaust and suction pipe 424 to the outside of the space, thereby realizing the exhaust function of the exhaust and suction pipe 424; Since the output end of the exhaust pipe 424 is close to the heat sink fins arranged on the water pump motor 300, the exhaust pipe 424 can continuously change the flow direction of the air around the heat sink fins during the air extraction and exhaust process, and accelerate the flow rate of the air around the heat sink fins, thereby significantly improving the heat exchange efficiency and heat exchange quality between the heat sink fins and the air. It is not necessary to add an additional driving source and reduce the dependence on external energy, so as to achieve stable heat dissipation and energy saving and efficiency improvement of the water pump. It is suitable for water pumps of various types and specifications, and has strong versatility and flexibility. The above is the working principle of the energy-saving water pump with stable heat dissipation.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
