Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic stations, and particularly relates to a cooling and detection mechanism for a hydraulic station. Background Technique

[0002] A hydraulic station is a hydraulic source device composed of a hydraulic pump, a driving electric motor, an oil tank, a direction valve, a throttle valve, an overflow valve, etc., or a hydraulic device including a control valve. It supplies oil according to the flow direction, pressure, and flow rate required by the driving device. The temperature of the hydraulic oil in the hydraulic station remains within a safe range during normal circulation. If the temperature of the hydraulic oil is too high and not cooled in time, the viscosity of the hydraulic oil will be reduced, affecting the working efficiency of the hydraulic station.

[0003] The existing Chinese utility model patent with the reference publication number: CN216382103U discloses a cooling and detection mechanism for a hydraulic station. A cooling and detection mechanism for a hydraulic station includes an oil pump motor and an oil pump arranged at the upper end of the hydraulic station. The lower end of the oil pump is connected with a oil pipe extending into the inner cavity of the hydraulic station. A temperature and oil temperature sensor connected to the peripheral surface of the oil pipe is arranged at the upper end of the inner cavity of the hydraulic station. A cooling annular pipe is wound around the peripheral surface of the lower end of the oil pipe. A cooling box communicated with the output end of the cooling annular pipe is arranged on the inner bottom wall of the hydraulic station. The upper end of the cooling box is communicated with the input end of the cooling annular pipe through a pump body. A liquid cooler is arranged inside the cooling box. By detecting the surface temperature of the oil pipe through the temperature and oil temperature sensor, and cooperating with the arrangement of the cooling annular pipe and the pump body, rapid cooling of the oil pipe can be achieved, ensuring the normal operation of the hydraulic station, reducing the failure rate of the hydraulic station. At the same time, the use of the cooling annular pipe in cooperation with the cooling box and the liquid cooler realizes the recycling of the coolant, saving existing resources.

[0004] The existing cooling equipment generally takes away the heat of the hydraulic oil through circulating water. Due to the influence of the specific heat capacity of water, this heat exchange method has low efficiency and cannot quickly take away the heat of the hydraulic oil. At the same time, the existing cooling equipment cannot adjust the heat exchange efficiency according to the temperature of the hydraulic oil during use. For a period of time after the hydraulic equipment starts, the temperature of the hydraulic oil does not change significantly. At this time, the cooling equipment still operates at full power, causing energy waste. Content of the Utility Model

[0015] Compared with the prior art, the utility model provides a temperature reduction detection mechanism for a hydraulic station, which has the following beneficial effects:

[0016] 1. Through the setting of the compressor in the utility model, the compressor can compress the gaseous cooling medium. After being compressed, the cooling medium will enter the inside of the heat dissipation pipe in a high-pressure gaseous state.

[0027] Flange structures are provided at the upper and lower ends of the oil pipe 1. The oil temperature sensor 12 penetrates through the end of the oil pipe 1 and is located at the center of the oil pipe 1, and the oil temperature sensor 12 is located below the spiral pipe 13. The center of the spiral structure of the spiral pipe 13 coincides with the center of the oil pipe 1. The upper and lower ends of the spiral pipe 13 penetrate through the oil pipe 1 and extend from the inside of the oil pipe 1 to the outside of the oil pipe 1. The throttle 15 is fixedly installed at the end of the one-way valve 14 at the lower end of the spiral pipe 13. The other end of the throttle 15 is communicated with the heat dissipation pipe 16. The heat dissipation pipe 16 is communicated with the compressor 18 through the adapter pipe 17. The heat dissipation pipe 16 is a continuously bent structure. The air inlet of the compressor 18 is communicated with the elbow 19. The front end of the connecting pipe 110 is connected to the one-way valve 14 at the upper end of the spiral pipe 13. The flow directions of the one-way valves 14 fixedly installed at the upper and lower ends of the spiral pipe 13 are opposite. The flow direction of the one-way valve 14 at the upper end of the spiral pipe 13 is from the inside of the spiral pipe 13 to the connecting pipe 110. The flow direction of the one-way valve 14 at the lower end of the spiral pipe 13 is from the throttle 15 to the inside of the spiral pipe 13. The heat conducting fins 111 are equidistantly installed on the outside of the horizontal structure of the heat dissipation pipe 16 before and after. The material of the heat conducting fins 111 is copper. The air outlet direction of the fan 112 points to the heat conducting fins 111.

[0028] Specifically, the oil pipe 1 can restrict the hydraulic oil from passing through the spiral pipe 13. The PLC controller 11 can adjust the power of the compressor 18 and the fan 112 according to the detection data of the oil temperature sensor 12. The oil temperature sensor 12 can monitor the temperature of the hydraulic oil. The spiral pipe 13 can facilitate heat transfer. The one-way valve 14 can restrict the flow direction of the cooling medium. The throttle 15 can facilitate the conversion of the high-pressure and low-temperature gaseous cooling medium into a liquid state. The heat dissipation pipe 16 can facilitate the discharge of heat from the compressed cooling medium. The adapter pipe 17 can facilitate the connection between the compressor 18 and the heat dissipation pipe 16. The compressor 18 can compress the gaseous cooling medium to facilitate the transformation of the gaseous cooling medium into a liquid state. The elbow 19 and the connecting pipe 110 can facilitate the return of the cooling medium. The heat conducting fins 111 can facilitate heat dissipation. The fan 112 can generate an air flow to facilitate the removal of the heat generated after the compression of the cooling medium.

[0029] In use, the compressor 18 can compress the gaseous cooling medium. The compressed cooling medium will enter the interior of the heat dissipation pipe 16 in a high-pressure gaseous state. The heat released after the compression of the cooling medium is absorbed by the heat dissipation pipe 16 and the heat conduction fins 111. The airflow generated by the fan 112 takes away the heat to cool the high-pressure gaseous cooling medium. The high-pressure gaseous cooling medium will be converted into a liquid state after passing through the throttler 15 and enter the interior of the spiral pipe 13 through the one-way valve 14. The center of the spiral structure of the spiral pipe 13 coincides with the center of the oil pipe 1. The upper and lower ends of the spiral pipe 13 penetrate the oil pipe 1 and extend from the interior of the oil pipe 1 to the exterior of the oil pipe 1. The normal-pressure liquid cooling medium in the spiral pipe 13 will quickly evaporate and absorb heat within the spiral structure of the spiral pipe 13, thereby taking away the heat of the hydraulic oil and returning to the compressor 18 in a gaseous state through the one-way valve 14 at the upper end of the spiral pipe 13, the connecting pipe 110, and the elbow 19 to form a cycle. This method can improve the cooling efficiency. The oil temperature sensor 12 penetrates the end of the oil pipe 1 and is located at the center of the oil pipe 1, and the oil temperature sensor 12 is located below the spiral pipe 13. The hydraulic oil enters the oil pipe 1 from above and is discharged from the lower part of the oil pipe 1 after passing through the spiral pipe 13. The oil temperature sensor 12 can monitor the temperature of the hydraulic oil after passing through the spiral pipe 13 and transmit the monitoring data to the PLC controller 11. The PLC controller 11 can dynamically adjust the power of the compressor 18 and the fan 112 according to the monitoring data. After being compressed, the cooling medium will be in a high-pressure state. The rotation speed of the fan 112 directly affects the heat released by the high-pressure cooling medium. After the cooling medium releases heat through compression, it needs to absorb heat to return to the normal temperature and pressure state. By adjusting the temperature of the cooling medium entering the interior of the spiral pipe 13, the upper limit of the heat that the cooling medium can absorb is controlled to control the cooling efficiency.
