Description
Technical Field

A hydraulic station is a device composed of a hydraulic pump, a liquid storage tank, etc. When in use, the hydraulic pump extracts hydraulic oil and transports it to external devices for use. After use, it will flow back into the liquid storage tank. During the reciprocating use of the hydraulic oil, heat will be generated, and the increase in the heat of the hydraulic oil will affect its performance.
[0003] Currently, the method for cooling hydraulic oil is to transport the hydraulic oil into a pipe body, and a cooling device is arranged in the middle section of the pipe body.

[0004] Although the above method can cool the hydraulic oil, when spraying cold water on the pipe body, water vapor will be generated. The water vapor will slowly rise around the pipe body, and this surrounding steam will slowly heat the pipe body again.

Embodiment
[0029] Referring to Figures 1-4 , the present utility model provides a technical solution: a hydraulic station cooling system, including a liquid storage tank 1 and a cooling mechanism 3, and a liquid pumping pump 2 is fixedly installed on the top of the liquid storage tank 1. The cooling mechanism 3 includes a hollow chamber 31, the hollow chamber 31 is fixedly installed on the top of the liquid storage tank 1, an infusion tube 311 is arranged inside the hollow chamber 31, a circular cylinder 32 is fixedly installed inside the liquid storage tank 1 and is arranged inside the hollow chamber 31, the infusion tube 311 is wound inside the circular cylinder 32, and a semiconductor refrigeration sheet 33 is fixedly installed inside the circular cylinder 32.
[0030] In a preferred embodiment, a circular tube 4 is fixedly installed at the liquid inlet end of the liquid extraction pump 2. One end of the circular tube 4 is fixedly installed inside the liquid storage tank 1. One end of the infusion tube 311 is arranged at the liquid outlet end of the liquid extraction pump 2, and the other end of the infusion tube 311 is fixedly installed inside the liquid storage valve body 5. The circular tube 4 and the infusion tube 311 are respectively installed at the liquid inlet end and the liquid outlet end of the liquid extraction pump 2. The liquid inside the liquid storage tank 1 is extracted through the circular tube 4, and the hydraulic oil is transported into the liquid storage valve body 5 through the infusion tube 311 and then transmitted to external equipment, so as to enable the normal use of the external equipment.
[0031] In a preferred embodiment, a liquid extraction machine 6 is fixedly installed at the top of the hollow chamber 31. A pipeline 7 is fixedly installed at the liquid inlet end of the liquid extraction machine 6, and a circular tube 8 is fixedly installed at the liquid outlet end. One end of the pipeline 7 and one end of the circular tube 8 are respectively installed inside the circular cylinder 32. There is water inside the circular cylinder 32 for cooling and temperature reduction of the infusion tube 311. By installing the pipeline 7 at the liquid inlet end of the liquid extraction machine 6 and the circular tube 8 at the liquid outlet end, and extracting the coolant inside the circular cylinder 32 through the pipeline 7 and then returning it to the inside of the circular cylinder 32 through the circular tube 8 again, the coolant inside the circular cylinder 32 can circulate to improve the cooling effect of the coolant.
[0032] In a preferred embodiment, a pressure sensor 9 and a liquid level sensor 10 are fixedly installed at the top of the liquid storage tank 1. The hydraulic oil of this device is stored inside the liquid storage tank 1. To avoid that excessive air pressure or excessive liquid volume inside the liquid storage tank 1 will affect the normal use of the hydraulic oil inside the liquid storage tank 1, the pressure sensor 9 and the liquid level sensor 10 are used to detect the air pressure and liquid level inside the liquid storage tank 1 to ensure the normal use of the hydraulic oil.
[0033] A certain amount of coolant will be filled inside the circular cylinder 32. The liquid extraction machine 6 controls the circulation of the coolant so that only the coolant at the upper position of the circular cylinder 32 can flow, while the coolant at the bottom is relatively static. To enable the coolant at the bottom to also flow, a stirring mechanism 11 is installed inside the circular cylinder 32. The stirring mechanism 11 includes a mounting plate 111, a rotating shaft 112, and a driving wheel 113. The mounting plate 111 is fixedly installed inside the circular cylinder 32, and a number of round holes 12 are provided on the upper surface of the mounting plate 111. The upper end of the rotating shaft 112 is fixedly connected to the driving wheel 113. The position of the driving wheel 113 corresponds to the position of one end of the circular tube 8. The rotating shaft 112 is rotated by spraying water on the driving wheel 113. The bottom end of the rotating shaft 112 is fixedly installed with a stirring roller 13. The bottom of the stirring roller 13 is slidably connected to the inner bottom of the circular cylinder 32. A water outlet pipe 14 is fixedly installed inside the circular cylinder 32 and extends outside the hollow chamber 31. A control valve is installed outside the water outlet pipe 14.
[0034] In actual use, a rotatable rotating shaft 112 is installed inside the circular cylinder 32. When the liquid pumping machine 6 pumps water, the water is sprayed out through the inside of the circular pipe 8, spraying water at the position facing the driving wheel 113. The driving wheel 113 will rotate under the impact of the water, and the rotating shaft 112 will be driven to rotate under the rotation of the driving wheel 113, so that the stirring roller 13 rotates. The stirring roller 13 stirs the coolant at the bottom end inside the circular cylinder 32, continuously stirring the bottom coolant, so as to mix it with the coolant at the upper end, improving the cooling effect of the overall coolant and meeting the use requirements.
[0035] Specifically, the working process or principle of a hydraulic station cooling system is as follows: Currently, the method of cooling hydraulic oil is to transport the hydraulic oil into the pipe body, and a cooling device is arranged at the middle section of the pipe body. By spraying cold water on the outer surface of the pipe body, the temperature of the pipe body is reduced, indirectly cooling the hydraulic oil.
[0036] Although the above method can cool the hydraulic oil, when spraying cold water on the pipe body, water vapor will be generated. The water vapor will slowly rise around the pipe body, and this surrounding steam will slowly heat the pipe body again. As a result, after the hydraulic oil is cooled for a period of time, it will be heated again, reducing the cooling effect of the hydraulic oil. Therefore, this device is designed to solve this problem.
[0037] The hydraulic oil inside the infusion pipe 311 can be cooled and its temperature can be reduced through this device, enabling the normal use of the hydraulic oil. The specific operation is as follows: Connect to an external power supply. In actual use, connect an external oil delivery pipe to one of the liquid storage valve bodies 5, and the remaining liquid storage valve bodies 5 are in a closed state. The liquid pumping pump 2 pumps out the hydraulic oil inside the liquid storage tank 1 and transports it through the infusion pipe 311 into the liquid storage valve body 5, and then into the external oil delivery pipe. The oil delivery pipe transports the hydraulic oil to external equipment, enabling the normal use of the equipment.
[0038] Since the infusion pipe 311 passes through the inside of the hollow chamber 31 and is wound around the outside of the circular cylinder 32, and the infusion pipe 311 transports oil for use on external equipment, a semiconductor refrigeration sheet 33 is installed inside the circular cylinder 32 in this device, and a certain amount of water is filled inside the circular cylinder 32. By cooling the water with the semiconductor refrigeration sheet 33, the outer surface of the circular cylinder 32 can also be cooled. When the hot oil flows through the inside of the infusion pipe 311, the temperature of the infusion pipe 311 can be reduced to cool the oil inside, achieving the cooling of the hydraulic oil and enabling the normal use of the hydraulic oil.
[0039] To improve the refrigeration effect, the liquid pumping machine 6 pumps out and then transports back the water inside the circular cylinder 32, circulating it, which can improve the cooling effect of the water inside the circular cylinder 32. During the transportation process of the hydraulic oil, the temperature of the hydraulic oil can be continuously reduced to meet the use requirements.
[0040] In actual operation, the water inside the circular cylinder 32 is pumped out by the liquid pump 6 and then transported back into the circular cylinder 32, only causing the water at the upper end of the water level inside the circular cylinder 32 to flow, while the water at the bottom position inside the circular cylinder 32 is equivalent to being in a static state at the upper end. This results in a general cooling effect of the water at the bottom position, thus reducing the cooling effect on the external oil pipeline. Therefore, in order to enable the water at the bottom position inside the circular cylinder 32 to be cooled as well, a rotatable rotating shaft 112 is installed inside the circular cylinder 32. When the liquid pump 6 pumps water, the water is sprayed out through the inside of the circular pipe 8, spraying water directly at the position of the driving wheel 113. Under the impact of the water, the driving wheel 113 will rotate, and under the rotation of the driving wheel 113, the rotating shaft 112 will be driven to rotate, thereby causing the stirring roller 13 to rotate.
[0041] The stirring roller 13 is arranged at the bottom position inside the circular cylinder 32. Under the stirring of the stirring roller 13, the water at the bottom position will be stirred, so that the water at the bottom position becomes active and mixes with the water at the upper end position. The continuous stirring of the water inside the circular cylinder 32 will enhance the cooling effect of the semiconductor refrigeration sheet 33 on the water, avoid the temperature difference between the upper and lower ends, and meet the usage requirements.
[0042] This device installs a water outlet pipe 14 on the circular cylinder 32, which can lift up to make the water inside the circular cylinder 32 smoother, avoid the growth of bacteria and corrosion of the semiconductor refrigeration sheet 33, and the water used inside the circular cylinder 32 in this device is a special coolant, which will not corrode the semiconductor refrigeration sheet 33 itself, so that the semiconductor refrigeration sheet 33 can be used normally.
[0043] It should be noted that the liquid pump 2, the liquid pump 6, the pressure sensor 9 and the liquid level sensor 10 are devices or equipment existing in the prior art, or devices or equipment that can be realized by the prior art. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail here.
