Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy projects, in particular to a full-circulation water cooling system for a water-cooled motor in a pump station. Background Art

[0002] In water conservancy projects, in order to ensure the rational allocation and use of water resources, water resources are usually transported and distributed through pumping stations to achieve rational use of water resources. During the operation of water conservancy pumping stations, the motor equipment of the pumping station is generally cooled by a water-cooled motor full-circulation water cooling system to ensure the normal operation of the motor, thereby achieving stable allocation of water resources.

[0003] In the Chinese patent application number CN202023098926.9, a full-circulation water cooling system for a water-cooled motor in a pump station is proposed. The utility model has a simple structure, is easy to install, and is economical and practical. It utilizes the pressure difference between the water inlet pipe end and the water outlet pipe end of the water pump itself to realize the fully closed self-circulation of the water-cooled motor in the pump station. Water circulation can be realized without the need for high-level water tanks or special water pumps and other equipment, thereby reducing the installation and operation costs of the cooling system, and no additional cooling water source is required, and no cooling water is discharged to the outside; at the same time, the length of the special cooling water pipe is also reduced, material costs are saved, and equipment costs such as high-level water tanks or special water pumps are saved, and the area occupied by the pump room is effectively saved; however, when the existing water cooling system is in use, the circulating water will not be subjected to heat conduction and cooling treatment, which may easily cause the water in the water tank to rise in temperature after multiple cycles of cooling, resulting in a decrease in the cooling effect on the pump station motor, thereby reducing the working efficiency of the water cooling system and affecting the practicality of the water cooling system.

[0004] Therefore, it is necessary to improve the prior art to solve the above-mentioned technical problems. Utility Model Content

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] The utility model provides Figure 1 A full-circulation water cooling system for a water-cooled motor in a water conservancy project pump station is shown, comprising:

[0027] A base 1, on which a chassis 5 is mounted, and inside which a motor 4 is mounted;

[0028] The water circulation cooling component includes a water tank 14 fixed on the top of the base 1 and a water pump 2 and a circulation pump 3 respectively installed on both sides of the top of the base 1. A cooling pipe 6 is embedded in the inner wall of the chassis 5. A water inlet pipe 9 is connected between the water inlet end of the water pump 2 and the water tank 14, and a water delivery pipe 7 is connected between the water outlet end of the water pump 2 and the water inlet of the cooling pipe 6. A water outlet pipe 10 is connected between the water inlet end of the circulation pump 3 and the water outlet of the cooling pipe 6. Circulation pipes 8 are connected between the two ends of the heat exchange tube 11 and the water outlet end of the circulation pump 3 and the water tank 14. A water injection pipe 15 is connected to one side of the water tank 14. A heat conduction pipe 12 is provided on the outer sleeve of the heat exchange tube 11, and the outer wall of the heat conduction pipe 12 is provided with evenly distributed through holes.

[0029] As can be seen from the above, when in use, the cooling medium inside the water tank 14 is first transported to the inside of the water pipe 7 through the water pump 2 through the water inlet pipe 9, and then the internal cooling medium is transferred to the cooling pipe 6 embedded in the chassis 5 through the water pipe 7, so that the cooling medium flows through the cooling pipe 6 inside the chassis 5, and the motor 4 inside the chassis 5 is cooled. Subsequently, the cooling medium inside the cooling pipe 6 is transported to the circulation pipe 8 through the water outlet pipe 10 by the circulating pump 3, and then transported to the water tank 14, thereby realizing the circulation heat dissipation of the motor 4 and ensuring the normal operation of the pump station motor.

[0030] refer to Figure 2 and Figure 3 As shown, an air-cooling cooling component is used to cool the cooling medium in the water circulation cooling component, and the air-cooling cooling component includes a cooling box 13 installed on a base 1 and a first shaft and a second shaft 20 rotatably installed on one side of the cooling box 13. One end of the first shaft and the second shaft 20 are both equipped with fan blades 21, and the cooling box 13 is provided with an air inlet 16 and an air outlet 17 on opposite sides, and a heat exchange tube 11 is installed inside the cooling box 13. A transmission component is connected between the two fan blades 21 and the water circulation cooling component, and the transmission component includes a belt 19 connected between the first shaft and the second shaft 20. One end of the second shaft 20 extends to the inside of the water pipe 7 and is equipped with a rotating paddle 25. An installation groove is provided on the cooling box 13, and a dustproof net 18 that blocks the air inlet 16 is inserted in the installation groove, and a handle is installed on the top of the dustproof net 18.

[0031] Through the above technical solution:

[0032] When in use, while the cooling medium enters the heat exchange tube 11 through the circulation tube 8, the cooling medium flowing in the water pipe 7 drives the rotating paddle 25 to rotate, thereby driving the second shaft 20 to rotate. The rotation of the second shaft 20 drives the fan blades 21 to rotate in a circle with it as the center, and the top fan blades 21 are driven by the belt 19 to rotate accordingly, thereby generating wind force to blow to the surface of the heat exchange tube 11, thereby forming a heat conduction function for the cooling medium inside the heat exchange tube 11, so that the cooling medium inside the heat exchange tube 11 can be quickly cooled down. , so that the temperature of the cooling medium will not rise rapidly when the motor 4 is circulated with water for cooling. In addition, the dust-proof net 18 is arranged so that the air inlet 16 can block flying insects, dust and other garbage during the air intake process to prevent them from entering the cooling box 13 and affecting the heat exchange tube 11. At the same time, after pulling the dust-proof net 18 by the handle, the dust-proof net 18 can be pulled out of the cooling box 13 to form a separate cleaning of the dust-proof net 18. Through the rapid heat conduction of the cooling medium inside the heat exchange tube 11, the utility model has a better effect on the water circulation cooling of the pump station motor 4.

[0033] In addition, refer to Figure 4 As shown, a movable plate 24 that can be raised and lowered is provided at the inner bottom of the water tank 14, and cleaning plates 23 are installed around the outer wall of the movable plate 24. The cleaning plate 23 contacts the inner wall of the water tank 14. The movable plate 24 is connected to a power member that drives it to rise and fall along the inside of the water tank 14. The power member includes an electric push rod 22 installed at the bottom end of the water tank 14. The telescopic end of the electric push rod 22 is in the water tank 14 and is fixedly connected to the bottom of the movable plate 24.

[0034] Through the above technical scheme: when in use, when the cooling medium in the water tank 14 is stored for a long time, more dirt will be generated. When there is a lot of dirt inside the water tank 14, the electric push rod 22 drives the movable plate 24 to move up and down on the inner wall of the water tank 14. The up and down movement of the movable plate 24 drives the up and down movement of the cleaning plate 23, so that the cleaning plate 23 pushes the dirt inside the water tank 14 to the top, thereby forming a cleaning effect on the dirt. By cleaning the water tank 14, the internal cooling medium of the circulating cooling of the utility model is cleaner and more stable when used, which increases the service life of the water tank 14 and avoids damage to the water tank 14 caused by a lot of dirt inside the water tank 14, so as to ensure the normal use of the water tank 14.

[0035] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions recorded in the aforementioned embodiments and any equivalent replacement of some of the technical features therein, any modification, equivalent replacement, and improvement made are all within the protection scope of the present invention.
