[0024] Embodiment 1

[0025] Such as Figure 1- As shown in the figure, the present utility model provides a technical solution: a heat dissipation device for a hydraulic pump station, including: a heat dissipation mechanism 1, an auxiliary mechanism 2 is arranged outside the heat dissipation mechanism 1. The heat dissipation mechanism 1 includes an exhaust pipe 13. One end of the exhaust pipe 13 is provided with a hollow plate 12. One end of the exhaust pipe 13 is fixedly communicated with one side of the hollow plate 12. A labyrinth pipe 16 is arranged on the inner wall of the hollow plate 12. The inner wall of the hollow plate 12 is fixedly connected with the outer end of the labyrinth pipe 16. A diversion plate 19 is arranged on one side of the hollow plate 12. One side of the hollow plate 12 is fixedly connected with one side of the diversion plate 19. One end of the labyrinth pipe 16 is provided with a negative pressure pump 15. One end of the labyrinth pipe 16 is fixedly communicated with one end of the negative pressure pump 15. The other end of the negative pressure pump 15 is provided with a liquid box 14. The other end of the negative pressure pump 15 is fixedly communicated with the inside of the liquid box 14. A bottom plate 11 is arranged on the bottom side of the liquid box 14. The bottom side of the liquid box 14 is fixedly connected with the top side of the bottom plate 11. A bottom support 18 is arranged on the top side of the bottom plate 11. The top side of the bottom plate 11 is fixedly connected with the bottom side of the bottom support 18. One end of the bottom support 18 is provided with a return box 17. One end of the bottom support 18 is fixedly connected with the bottom side of the return box 17. The inside of the return box 17 is fixedly communicated with one end of the labyrinth pipe 16. A side plate 110 is arranged on one side of the hollow plate 12. One side of the hollow plate 12 is fixedly connected with one side of the side plate 110. An exhaust fan 111 is arranged on the inner wall of the side plate 110. The inner wall of the side plate 110 is fixedly connected with the outer side of the exhaust fan 111. One end of the diversion plate 19 is exactly corresponding to one side of the exhaust fan 111. One end of the diversion plate 19 corresponds to one end of the exhaust pipe 13. One end of the exhaust pipe 13 is exactly corresponding to one end of the pump body 112.

[0026] In this embodiment, when the heat dissipation device for the hydraulic pump station is in use, it will dissipate heat from the pump body 112 in a double-cycle form. Since there are heat dissipation holes at the rear position of the pump body 112, the coolant in the liquid box 14 is introduced into the labyrinth pipe 16 by the negative pressure pump 15. The labyrinth pipe 16 is in an S shape and has many paths, so the flow rate of the coolant will be delayed on the way. At this time, the exhaust fan 111 is started so that the wind direction is conveyed towards the labyrinth pipe 16. An exhaust pipe 13 is installed on one side of the labyrinth pipe 16, and one end of the exhaust pipe 13 corresponds to the heat dissipation hole at the rear of the pump body 112. Under the action of the exhaust fan 111, the cold air dissipated around the labyrinth pipe 16 will enter the exhaust pipe 13 and then be introduced into the heat dissipation hole of the pump body 112, forming a continuous cooling flow. It can keep the temperature inside the pump body 112 stable, prevent overheating, and when the cold air reaches the port of the exhaust pipe 13, part of it will dissipate around. Therefore, a diversion plate 19 is installed around it, and the cold air is introduced to one side of the exhaust fan 111 through the diversion plate 19. In this way, the exhaust fan 111 conveys the cold air to the labyrinth pipe 16 again. When the coolant flows to the end of the labyrinth pipe 16, it will enter the return box 17 and be introduced into the liquid box 14 again by the return box 17, thus realizing a closed circulation system to ensure the continuous flow of the coolant and effective heat dissipation. Through this double-cycle system, sufficient heat exchange can be carried out, enhancing the cooling effect of the pump body 112;

The pump body 112 is arranged inside the rubber pad 22, and the inner side of the rubber pad 22 is fixedly connected to the outer side of the pump body 112.

[0029] In this embodiment, a rubber pad 22 is designed inside the rectangular frame 21, and the rubber pad 22 is fixedly connected to the pump body 112. The rubber pad can effectively absorb the vibration generated during the operation of the pump body 112, reduce the transmission of vibration in the whole assembly, thereby reducing the noise level of the system. By eliminating vibration, the rubber pad 22 can suppress the resonance phenomenon of the system and avoid equipment damage and performance decline caused by resonance.
