Description

Technical Field

[0001] The utility model relates to the technical field of water pump cooling equipment, in particular to an automatic water pump cooling device. Background Art

[0002] At present, water accumulation is unavoidable on the working surface during existing tunnel construction, civil engineering construction, and road and bridge construction. The accumulation is quite large, which has a significant impact on the cleaning of the bedrock surface, the cleanliness of the poured concrete surface, and the appearance quality. Regarding shallow water accumulation in the tunnel, small water-cooled pumps are often used for pumping and draining. However, small water-cooled pumps mostly rely on heat conduction into the surrounding water to dissipate heat. The use of small water-cooled pumps to pump and drain shallow water has the following characteristics: First, the depth of the accumulated water is relatively shallow, and most of the pump is not submerged in the water, leaking into the air; second, the accumulated water area is large, and the total amount of accumulated water is large, requiring continuous pumping and drainage; third, there is a lot of localized water accumulation, and there are many points of water accumulation. This results in the pump not being able to dissipate heat well during operation, which can easily cause the temperature to rise during long-term operation, damaging the pump and shortening its service life. To address this problem, a cooling sleeve is often installed on the outside of the water pump housing, and heat is dissipated through the cooling medium within the cooling sleeve (for example, the water cooling structure for a water pump motor disclosed in Chinese patent document publication number CN113241881A). However, the flow of the cooling medium within the cooling sleeve requires reliance on other equipment, which is costly. In addition, since the cooling sleeve is usually only suitable for water pumps of a specified model and size, a specific cooling sleeve must be specially manufactured for each different size, resulting in poor applicability.

[0009] As a further improvement of the above technical solution: the spray assembly includes a bent tube and a nozzle, one end of the bent tube is arranged on the second fixed rod and connected to the drainage pipe, and the nozzle is arranged at the other end of the bent tube and is located on the side or above the water pump.

[0010] As a further improvement of the above technical solution: the bending tube is rotationally connected to the drainage tube, and the spraying direction of the nozzle deviates from the rotation axis of the bending tube.

[0011] As a further improvement of the above technical solution: the bending tube is connected to the drainage tube through a rotary joint, the rotary joint is provided on the second fixing rod, and the bottom of the rotary joint is provided with a support seat that can be supported on the water pump.

[0022] Figure 1 and Figure 2 An embodiment of the automatic cooling device for a water pump of the present invention is shown. The automatic cooling device for a water pump of this embodiment includes a base 1, a fixing frame 2, a transition pipe 3, a drainage pipe 4, a water pump 5 and a spray assembly 7. The water pump 5 is arranged on the base 1, and a fixing frame 2 is provided on the base 1. The transition pipe 3 is arranged on the fixing frame 2, and one end of the transition pipe 3 is connected to the water outlet of the water pump 5, and the other end of the transition pipe 3 is connected to the drain pipe 6. The spray assembly 7 is arranged on the fixing frame 2 for spraying cooling water to the water pump 5, and the drainage pipe 4 connects the transition pipe 3 and the spray assembly 7.

[0023] The automatic water pump cooling device of this embodiment optimizes the water flow path by introducing a transition pipe 3 between the water pump 5 and the drain pipe 6 and connecting the spray assembly 7 and the transition pipe 3 via a drainage pipe 4. During operation, the pump 5, powered by its own power, first draws water through the transition pipe 3. A portion of the water is then effectively directed to the drainage pipe 4. The water is then diverted through the drainage pipe 4 to the spray assembly 7, which sprays this water onto the surface of the pump 5, achieving an automatic cooling effect. The entire cooling process requires no additional drive equipment, resulting in a simple structure and easy use and maintenance, saving both installation and operating costs. Furthermore, since the pump 5 and the mounting bracket 2 are both mounted on the base 1, and the transition pipe 3 and spray assembly 7 are both mounted on the mounting bracket 2, this structural layout ensures that the relative positions of the various components of the pump 5 remain stable during use, thereby ensuring that the water discharged from the drainage pipe 4 can continuously and stably cool the surface of the pump 5, improving the reliability and stability of the pump 5 during long-term pumping and drainage operations.

[0024] See Figure 1Furthermore, in this embodiment, the fixing frame 2 includes a first fixing rod 21 and a second fixing rod 22. The first fixing rod 21 is mounted on the base 1. One end of the second fixing rod 22 is mounted on the first fixing rod 21, and the other end protrudes above the water pump 5. The transition pipe 3 is mounted on the first fixing rod 21, and the spray assembly 7 is mounted on the protruding end of the second fixing rod 22. This provides a simple structure and reliable operation. Specifically, the transition pipe 3 can be secured to the first fixing rod 21 using multiple straps, and the drainage pipe 4 can also be secured to the second fixing rod 22 using multiple straps. This simple structure and convenient fixing facilitate stability of the transition pipe 3 and drainage pipe 4, as well as reliability during use.

[0025] Furthermore, in this embodiment, the transition pipe 3 is a telescopic pipe, and one end of the second fixed rod 22 is connected to the first fixed rod 21 via a lifting and adjusting assembly 23. By adjusting the position of the lifting and adjusting assembly 23 on the first fixed rod 21, the height of the spray assembly 7 can be adjusted, thereby cooling water pumps 5 of various sizes and models, providing flexibility. It should be noted that when fixing the position of the transition pipe 3, only the non-telescopic section of the transition pipe 3 is fixed to the first fixed rod 21, and the telescopic section of the transition pipe 3 is not fixed to the first fixed rod 21. Specifically, the non-telescopic section of the transition pipe 3 can be fixed to the first fixed rod 21 using components such as straps and clamps. Of course, the non-telescopic section of the transition pipe 3 can also be directly welded to the first fixed rod 21. The details will not be repeated here. Of course, in other embodiments, the transition pipe 3 can also be a hose. Due to the bendable and foldable nature of hoses, only a transition pipe 3 of sufficient length is required. Through reasonable layout, the height of the spray assembly 7 can also be adjusted in conjunction with the lifting and adjusting assembly 23. The details will not be repeated here.

[0026] See Figure 1 Furthermore, in this embodiment, the lifting and adjusting assembly 23 includes a first hoop body 231 and a second hoop body 232 arranged opposite each other. The ends of the first hoop body 231 and the second hoop body 232 are connected by bolts and tightened to the first fixing rod 21. The second fixing rod 22 is connected to the first hoop body 231. By loosening the nuts on the first hoop body 231 and the second hoop body 232, the position of the second fixing rod 22 relative to the first fixing rod 21 can be adjusted. By tightening the nuts, the second fixing rod 22 can be fixed to the first fixing rod 21. This simple structure and reliable use.

[0027] See Figure 1 and Figure 2Furthermore, in this embodiment, the spray assembly 7 includes a bent tube 71 and a nozzle 72. One end of the bent tube 71 is provided on the second fixed rod 22 and connected to the drainage tube 4. The nozzle 72 is provided at the other end of the bent tube 71 and is located on the side of the water pump 5. Of course, in other embodiments, the nozzle 72 may also be located above the water pump 5. Preferably, the bent tube 71 is rotationally connected to the drainage tube 4, and the spraying direction of the nozzle 72 deviates from the rotation axis of the nozzle 72. Specifically, the bent tube 71 is rotationally connected to the drainage tube 4 through a rotary joint 8. When water flows out from the nozzle 72, with the help of the reverse force of the water flow, the water flow pushes the bent tube 71 to rotate around the rotation axis of the rotary joint 8, so that the water flow ejected by the nozzle 72 during the rotation process can cool the sides around the water pump 5, thereby improving the heat dissipation effect and heat dissipation uniformity, and helping to avoid the generation of local hot spots.

[0028] See Figure 2 Furthermore, in this embodiment, a support base 9 is provided at the bottom of the rotary joint 8, which can be supported on the water pump 5. The support base 9 is rotatably connected to the rotary joint 8. The support base 9 can transmit the gravity of the spray assembly 7 and the rotary joint 8 to the water pump 5 through the support base 9, which helps to ensure the connection strength between the rotary joint 8 and the second fixing rod 22, and also helps to ensure the stability of the bending tube 71 during rotation. Preferably, the support base 9 is a rotating base. When supported on the water pump 5, it can rotate relative to the water pump 5, thereby avoiding affecting the rotation of the bending tube 71.

[0029] See Figure 1 and Figure 2 Furthermore, in this embodiment, a plurality of bent tubes 71 and nozzles 72 are provided, and each nozzle 72 is connected to each bent tube 71 in a one-to-one correspondence and arranged at intervals around the circumference of the water pump 5, and each bent tube 71 is arranged symmetrically with respect to the rotation axis of the bent tube 71, so that the water flow sprayed from each nozzle 72 can push each bent tube 71 to rotate in the same rotation direction, so that multiple nozzles 72 can spray and cool the water pump 5 while rotating together, further improving the cooling effect and cooling uniformity.

[0030] See Figure 1 Furthermore, in this embodiment, the base 1 includes a bearing sleeve 11 and a plurality of legs 12. The legs 12 are provided on the bearing sleeve 11 and spaced apart along the circumference of the bearing sleeve 11. The lower end of the water pump 5 is sleeved in the bearing sleeve 11 and extends below the bearing sleeve 11. The first fixing rod 21 is provided on the bearing sleeve 11. This effectively prevents the water pump 5 from being displaced due to vibration during use, ensuring that water flowing out of the drainage tube 4 can smoothly flow to the surface of the water pump 5.

[0031] See Figure 1Furthermore, in this embodiment, a regulating valve 10 is provided on the drainage pipe 4. The regulating valve 10 can be used to reasonably adjust the flow rate of water in the drainage pipe 4 according to the operating power of the water pump 5 to adapt to different cooling requirements of the water pump 5.

[0032] The assembly process of the water pump automatic cooling device of this embodiment is as follows:

[0033] First, disassemble the water pump 5 and other parts and transport them to the designated pumping location. Then, place the bottom of the water pump 5 in the bearing sleeve 11. Then, according to the height of the water pump 5, adjust the position of the second fixing rod 22 on the first fixing rod 21 through the lifting adjustment component 23, so that the support seat 9 abuts against the top of the water pump 5. At the same time, the transition pipe 3 is extended and retracted so that its length adapts to the height of the water pump 5. Then, connect one end of the transition pipe 3 to the water outlet of the water pump 5 and the other end to the drain pipe 6. Then use the drainage pipe 4 to connect the transition pipe 3 and the rotary joint 8. Then connect each bent pipe 71 to the rotary joint 8. Finally, start the water pump 5, adjust the flow rate in the drainage pipe 4 through the regulating valve 10, and each nozzle 72 begins to rotate around the water pump 5 while cooling the water pump 5. After cooling, turn off the water pump 5, separate the two ends of the transition pipe 3 from the water outlet of the water pump 5 and the drain pipe 6 respectively, adjust the position of the second fixing rod 22 on the first fixing rod 21, separate the support seat 9 from the water pump 5, and then take the water pump 5 out of the bearing sleeve 11. Disassemble the water pump 5 and other parts and transport them to the next pumping location, repeat the above steps to pump water until the pumping operation is completed.

Any person skilled in the art can, without departing from the scope of the present invention, utilize the technical content disclosed above to make many possible changes and modifications to the present invention, or modify it into equivalent embodiments with equivalent variations. Therefore, any simple modifications, equivalent variations, and modifications to the above embodiments that do not depart from the content of the present invention and are based on the technical essence of the present invention shall fall within the scope of protection of the present invention.
