Abstract
Description
Technical Field
[0001] The invention belongs to the field of cooling devices, and in particular relates to a heat pipe isolation type hydraulic station cooling device based on pressure control. Background Art
[0002] With the development of industrial technology, the existing technology, the oil transfer arm, also known as the marine oil transfer arm or marine liquid loading and unloading arm, is a special equipment installed on the dock to load and unload fluid materials between the dock and the tank ship. The oil transfer arm consists of an inner arm, an outer arm, and a rotary joint. The rotary joint connects the inner and outer arms to perform related operations, realizing the rotation of the outer arm. The oil transfer arm realizes the loading and unloading of materials through the inner and outer arms. In order to realize the hydraulic drive of the oil transfer arm, a hydraulic system is required.
[0003] Patent CN110145511A discloses a hydraulic oil cooling device within a hydraulic station, comprising an oil storage tank, the oil storage tank including a hot oil tank, one side of the hot oil tank being fixedly connected to a cold oil tank, one side of the outer wall of the hot oil tank being fixedly connected to a first oil pipe, the first oil pipe being fixedly connected to a first oil pump, the other end of the first oil pipe being fixedly connected to an oil-water filter, and one end of the oil-water filter being fixedly connected to a second oil pipe. This hydraulic oil cooling device within the hydraulic station utilizes a first three-way diverter valve, an air cooling device, and a water condenser. The first three-way diverter valve is used to divide the hot oil into two separate cooling paths, significantly improving cooling efficiency and providing effective hydraulic oil cooling. The cooled hydraulic oil is then collected into the oil storage tank via a second three-way diverter valve, achieving hydraulic oil circulation and resolving the problem of equipment downtime caused by excessively high hydraulic oil temperatures due to prolonged overload operation.
[0004] This device still has defects when in use. First, the previous hydraulic station cooling device uses an air cooling device, and a fan is directly installed on the hydraulic station to dissipate heat. This cooling speed is relatively slow, and it is difficult to meet the needs of continued cooling. Second, the thermal conductivity of the previous hydraulic station is relatively low. The thermal conductivity of the hydraulic oil and the hydraulic pipe is proportional to the contact area. The larger the contact area between the hydraulic oil and the hydraulic pipe, the easier it is for the hydraulic pipe to rupture. The smaller the contact area between the hydraulic oil and the hydraulic pipe, the smaller the flow rate of the hydraulic oil. Summary of the Invention
[0005] The purpose of the present invention is to address the deficiencies of the prior art and provide a heat pipe isolated hydraulic station cooling device based on pressure control. When the device is in use, the gear pump discharges the hydraulic oil from the output steel pipe during operation. The hydraulic oil inside the output steel pipe transfers heat to the heat sink at a high temperature. At the same time, the air compressor compresses the air inside the air compression box. The air inside the air compression box increases in temperature during compression. The fins and the fan quickly dissipate the heat of the compressed air. When the buffer valve is opened, the compressed air expands in the buffer tank and the temperature drops to become cold air. The cold air is blown into each ball cavity through a forked exhaust pipe. The cold air swirls in the ball cavity to quickly reduce the temperature, thereby solving the problems mentioned in the background technology.
[0006] To solve the above problems, the present invention provides the following technical solutions: a heat pipe isolation type hydraulic station cooling device based on pressure control, comprising an output oil tank and a return oil tank, a partition is provided in the middle of the output oil tank and the return oil tank, and a bottom plate is provided at the bottom end of the output oil tank and the return oil tank; a motor is provided at the top of the output oil tank, a gear pump is provided on the output shaft of the motor, an input steel pipe is provided at the input end of the gear pump, the input steel pipe extends to the interior of the output oil tank, an output steel pipe is provided at the output end of the gear pump, and a forked heat dissipation mechanism and an air-cooled heat dissipation mechanism are provided on the outer wall of the output steel pipe; a temperature buffer mechanism is also provided at the tail end of the output steel pipe, a return pipe extends from the interior of the return oil tank, and the hydraulic oil output by the output steel pipe is recovered to the interior of the return oil tank from the port of the return pipe.
[0007] When in use, the gear pump discharges the hydraulic oil from the output steel pipe during operation, and recovers the hydraulic oil from the return pipe after the work is completed. The heat generated by the hydraulic oil in the output steel pipe is cooled through the bifurcated heat dissipation mechanism and the air-cooled heat dissipation mechanism.
[0008] Furthermore, the forked heat dissipation mechanism includes two expansion joints on the outer side wall of the output steel pipe, and the side walls of the output steel pipe and the expansion joint are provided with fan-shaped arrays of diversion ports, and the diversion ports on the output steel pipe and the side walls of the expansion joint correspond to each other one by one. A diversion plate is fixedly installed on the outer side walls of the two expansion joints, and a fan-shaped array of diversion channels is provided on the side walls of the diversion plate. The diversion channels on the inner sides of the front and rear diversion plates are respectively connected by forked hydraulic pipes, and a diversion valve is provided in the middle position of the forked hydraulic pipe.
[0009] During use, when the staff encounters a situation where the hydraulic oil heats up rapidly, the diverter valve begins to open, allowing the hydraulic oil inside the output steel pipe to pass through the bifurcated hydraulic pipe and then converge into the output steel pipe. In this process, the contact area between the hydraulic oil and the pipe wall will increase without the risk of bursting, thus achieving the effect of auxiliary cooling.
[0010] Furthermore, the air-cooled heat dissipation mechanism includes a heat dissipation block, which is made of copper. The heat dissipation block is divided into two halves, the left and right halves of the heat dissipation block are clamped on the outer wall of the output steel pipe, and the gap between the heat dissipation block and the output steel pipe is filled with thermal conductive silicone. An air-cooling mechanism matching the heat dissipation block is provided on one side of the heat dissipation block.
[0011] When in use, the hydraulic oil inside the output steel pipe transfers heat to the heat sink at a high temperature, the heat sink increases the contact area with the air, and the air cooling mechanism cools the heat sink.
[0012] Furthermore, the air cooling mechanism includes a linear array of spherical cavities on the side wall of the heat dissipation block, an exhaust pipe is fixedly provided on the top of the heat dissipation block, a linear array of forked exhaust pipes is provided on the side wall of the exhaust pipe, the ends of the forked exhaust pipes are respectively inserted into the interior of the spherical cavities, and the exhaust pipes are connected to the source of cold air.
[0013] When in use, the bifurcated exhaust pipe blows air into each ball cavity, and the air swirls in the ball cavity to quickly reduce the temperature.
[0014] Furthermore, the cold air source includes an air compression box on the side wall of the return oil tank, an air compressor is provided at the top of the air compression box, fins are also provided on the side wall of the air compression box, a fan is provided on the side wall of the fin, the end of the exhaust pipe extends to the interior of the air compression box, and a buffer tank and a buffer valve are provided at the end of the exhaust pipe near the air compression box.
[0015] When in use, the air compressor compresses the air inside the air compression box. The temperature of the air inside the air compression box increases during compression. The fins and the fan quickly dissipate the heat of the compressed air. When the buffer valve is opened, the compressed air expands in the buffer tank and the temperature drops to become cold air. The cold air is blown into each ball cavity through the forked exhaust pipe. The cold air swirls in the ball cavity to quickly reduce the temperature.
[0016] Furthermore, the temperature buffer mechanism includes a built-in coil, and heat buffer tubes are provided at both ends of the built-in coil. The two ports of the built-in coil are connected to the outside of the output steel pipe through two heat buffer tubes. A through-hole matching the heat buffer tube is provided on the side wall of the output steel pipe. The through-hole and the outer wall of the output steel pipe are sealed. The two heat buffer tubes are connected to a circulating water source with a constant temperature.
[0017] When in use, constant temperature circulating water is circulated through the heat buffer tube and the built-in coil, which can prevent sudden changes in the temperature of the hydraulic oil and uneven temperature and density of the hydraulic oil, which will cause too large deviations in hydraulic oil metering.
[0018] Compared with the prior art, the embodiments of the present application have the following beneficial effects:
[0019] First, when the device is in use, the gear pump discharges the hydraulic oil from the output steel pipe during operation. The hydraulic oil inside the output steel pipe transfers heat to the heat sink at a high temperature. At the same time, the air compressor compresses the air inside the air compression box. The air inside the air compression box increases in temperature during compression. The fins and the fan quickly dissipate the heat of the compressed air. When the buffer valve is opened, the compressed air expands in the buffer tank and the temperature drops to become cold air. The cold air is blown into each ball cavity through the forked exhaust pipe. The cold air swirls in the ball cavity to quickly reduce the temperature.
[0020] Secondly, when workers encounter a situation where the hydraulic oil heats up rapidly, the diverter valve begins to open, allowing the hydraulic oil inside the output steel pipe to pass through the bifurcated hydraulic pipe and then converge into the output steel pipe. In this process, the contact area between the hydraulic oil and the pipe wall increases without the risk of bursting, thus achieving an auxiliary cooling effect;
[0021] Third, constant temperature circulating water is circulated through the heat buffer tube and the built-in coil, which can prevent the hydraulic oil from changing temperature suddenly. The temperature and density of the hydraulic oil are uneven, which will cause too large deviation in the hydraulic oil metering. The constant temperature circulating water inside the heat buffer tube and the built-in coil can prevent the hydraulic oil from changing temperature suddenly. BRIEF DESCRIPTION OF THE DRAWINGS
