DETAILED DESCRIPTION

[0023] The present application is further described in detail below in conjunction with the accompanying drawings.

[0024] Embodiment 1

[0025] Reference Figure 1 - 3. A hydraulic equipment cooling device, comprising:

[0026] Base 1; support column 17, fixedly arranged on base 1, four support columns 17 are arranged, box body 2 is fixedly installed on support column 17, motor 3 is fixedly installed on the side of box body 2, water pump 4 and refrigerator 5 are fixedly installed on base 1, oil inlet pipe 12 and oil outlet pipe 10 are fixedly connected to box body 2, and the same oil pipe 11 is fixedly connected to both oil inlet pipe 12 and oil outlet pipe 10;

[0027] The air cooling mechanism is arranged on the output shaft of the motor 3 and is used to cool the coolant.

[0028] The reflux mechanism is arranged on the box body 2 and is used to speed up the flow speed of the coolant in the box body 2.

[0029] In this embodiment, the air cooling mechanism includes a first transmission rod 6 and fan blades 8 . The first transmission rod 6 is fixedly connected to the output shaft of the motor 3 , and the fan blades 8 are fixedly connected to the first transmission rod 6 .

[0030] In this embodiment, the reflux mechanism includes a second transmission rod 7 and a reflux blade 9 . The second transmission rod 7 is rotatably connected to the housing 2 , and the reflux blade 9 is fixedly connected to the second transmission rod 7 .

[0031] In this embodiment, a water inlet pipe 16 and a water outlet pipe 13 are fixedly connected to the box body 2 , and the water inlet pipe 16 is fixedly connected to the refrigerator 5 .

[0032] In this embodiment, a spiral tube 14 is fixedly connected to the water outlet pipe 13, and the spiral tube 14 is fixedly connected to the water pump 4. The refrigerator 5 and the water pump 4 are fixedly connected with the same connecting tube 15. The first transmission rod 6 is fixedly connected with a worm 18, and the second transmission rod 7 is fixedly connected with a worm wheel 19. The worm 18 is meshingly connected with the worm wheel 19, and the first transmission rod 6 and the second transmission rod 7 are both rotatably connected with the same protective box 20.

[0033] The implementation principle of a hydraulic equipment cooling device in the embodiment of the present application is as follows: when working, the oil pipe 11 is connected to the hydraulic oil pipeline of the hydraulic equipment through the oil inlet pipe 12 and the oil outlet pipe 10. When the hydraulic equipment starts working, the hydraulic oil passes through the oil pipe 11, and the coolant in the box 2 cools the hydraulic oil in the oil pipe 11. When the temperature of the coolant in the box 2 rises, the motor 3, the water pump 4 and the refrigerator 5 are started. The water pump 4 draws out the coolant in the box 2 through the water outlet pipe 13 and the spiral tube 14, and sends it into the refrigerator 5 through the connecting pipe 15 for cooling. The cooled coolant re-enters the box 2 through the water inlet pipe 16 and cools the oil pipe 11 in the box 2. To cool down, the output shaft of the motor 3 drives the first transmission rod 6 to rotate, and the first transmission rod 6 drives the fan blades 8 to rotate. The fan blades 8 cooperate with the spiral tube 14, so that the wind blown by the fan blades 8 can cool down the coolant in the spiral tube 14. At the same time, the first transmission rod 6 drives the worm 18 to rotate, and the worm 18 drives the worm gear 19 to rotate through the meshing connection with the worm gear 19. The worm gear 19 drives the second transmission rod 7 to rotate, and the second transmission rod 7 drives the return fan blades 9 to rotate. The return fan blades 9 cooperate with the coolant in the box 2, so that the heat exchange rate of the coolant in the box 2 is improved, thereby avoiding the situation where the coolant in the box 2 has regional temperature differences.

[0035] The difference between the second embodiment and the first embodiment is that a liquid replenishing mechanism is provided in the box body 2, so that the cooling liquid reduced during the circulation process can be replenished in time to avoid affecting the cooling efficiency.
