Description

Technical Field

[0001] This invention relates to the field of hydraulic component technology, and in particular to a high-pressure, high-flow hydraulic component for real-time temperature control of hydraulic oil. Background Technology

[0002] When a hydraulic system operates under high pressure and high flow conditions, the hydraulic oil temperature rises rapidly due to continuous friction and energy loss. Excessive oil temperature leads to a decrease in hydraulic oil viscosity, deterioration of lubrication performance, accelerated component wear, and even problems such as system seal failure or hydraulic component jamming, severely impacting system stability and service life. Therefore, real-time temperature control of the hydraulic oil is crucial for ensuring the reliable operation of high-pressure, high-flow hydraulic systems.

[0003] Traditional hydraulic oil cooling methods often employ air cooling or simple water cooling circulation, but these suffer from low cooling efficiency and delayed temperature control. Especially under high-pressure, high-flow conditions, the hydraulic oil flows rapidly and experiences a large heat load, making it difficult for conventional cooling systems to respond quickly to oil temperature changes, and resulting in poor cooling uniformity. Furthermore, the delivery of hydraulic oil in hydraulic systems typically relies on pump and valve structures, which, after long-term operation, are prone to flow instability due to impurity accumulation or oil passage blockage, further exacerbating the temperature rise problem.

[0004] In existing technologies, some hydraulic systems attempt to cool the hydraulic oil through external coolant circulation or forced heat dissipation structures, but these often suffer from the following drawbacks: unreasonable coolant circulation path design and insufficient cooling efficiency; lack of dynamic anti-clogging mechanism during hydraulic oil delivery, making it prone to oil circuit blockage due to impurities or gas residue; and low integration of coolant filtration and circulation systems, making it difficult to achieve continuous and efficient utilization of the cooling medium. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the prior art where, under high pressure and high flow conditions, the hydraulic oil has a fast flow rate and a large heat load, making it difficult for conventional cooling systems to respond quickly to changes in oil temperature and resulting in poor cooling uniformity. In addition, the delivery of hydraulic oil in hydraulic systems usually relies on pump and valve structures, and after long-term operation, the flow rate is prone to unstable due to the accumulation of impurities or blockage of oil circuits, which further aggravates the temperature rise.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-pressure, high-flow hydraulic component with real-time temperature control of hydraulic oil, comprising: a base plate, a first coolant tank fixedly installed on the top of the base plate, a second coolant tank fixedly installed on the top of the base plate, a cooler fixedly installed on one side of the second coolant tank, a fixed U-shaped block fixedly installed at the bottom of the second coolant tank, a cylinder fixedly installed at the bottom of the second coolant tank, a movable U-shaped block fixedly installed at one end of the cylinder, a filter screen detachably connected to the opposite side of the movable U-shaped block and the fixed U-shaped block, an outlet pipe fixedly installed at the bottom of the second coolant tank, a one-way valve provided inside the outlet pipe, a collection box fixedly installed on the top of the first coolant tank, the collection box being located directly below the filter screen, an outer ring fixedly installed on the top of the base plate, and a thick pipe fixedly installed on the inner wall of the outer ring.

[0007] The technical effect of adopting the above-mentioned further solution is as follows: When the water pump is started by an external power source, the water pump draws out the cooling water from inside the first coolant tank through the input pipe. The water pump outputs the cooling water to the inside of the output pipe. The output pipe is wrapped around the outer surface of the thick pipe to cool the hydraulic oil inside, thereby reducing the temperature of the inner wall of the thick pipe and cooling the hydraulic oil inside. The water that has cooled the inner wall of the thick pipe is transported to the inside of the second coolant tank through the cooling pipe. The temperature of the circulating cooling water in the second coolant tank is cooled by starting the cooler and it can be reused. By turning the one-way valve, the cooled water in the second coolant tank enters the outer surface of the filter screen through the outlet pipe. The filter screen filters the water and reduces the impurities brought into the internal pipes of the cooling water, so as to prevent the pipes from being clogged by too many impurities. After filtration, the water enters the collection box and then enters the first coolant tank for reuse.

[0008] In a preferred embodiment, a hydraulic oil tank is fixedly installed at the top of the thick pipe, a water pump is fixedly installed on one side of the coolant tank, an input pipe is fixedly installed at the input end of the water pump, a cooling pipe is fixedly installed at the output end of the water pump, the output pipe is located on the inner wall of the outer ring, and a cooling pipe is fixedly installed at one end of the output pipe.

[0009] The technical effect of adopting the above-mentioned further solution is that the water cooled on the inner wall of the thick pipe is transported to the interior of the coolant tank two through the cooling pipe, and the temperature of the circulating coolant in the coolant tank two is cooled by starting the cooler so that it can be used again.

[0010] In a preferred embodiment, one end of the cooling pipe is fixedly installed on the inner wall of the coolant tank, a rubber hose is fixedly installed on one side of the thick pipe, an outer pipe is fixedly installed on one side of the rubber hose, an oil outlet is opened on one side of the rubber hose, a plurality of limiting rods are fixedly installed on one side of the rubber hose, a blocking block is movably sleeved on the outer surface of the plurality of limiting rods, and a spring is fixedly installed on one side of the blocking block.

[0011] The technical effect of adopting the above-mentioned further solution is that the hydraulic oil inside the rubber hose is squeezed into the interior of the outer tube through the oil outlet. When the block is not subjected to any external force, the spring limits the block, so that the block is located on the outer surface of the oil outlet and blocks the oil outlet. When the rubber hose is squeezed and returns to its original state, it avoids the hydraulic oil inside the outer tube from being absorbed into the interior of the rubber hose through the oil outlet.

[0012] In a preferred embodiment, the blocking block is located inside the oil outlet hole, the blocking block is located inside the outer tube, a temperature detector is installed inside the outer tube, an oil inlet box is fixedly installed on one side of the outer tube, a hydraulic cylinder is fixedly installed on one side of the oil inlet box, and a semi-circular block is provided on the outer surface of the rubber hose.

[0013] The technical effect of adopting the above-mentioned further solution is that the temperature detector is used to detect the temperature of the hydraulic oil inside the outer tube.

[0014] In a preferred embodiment, a semicircular block 2 is provided on the outer surface of the rubber hose, an electric push rod 1 is fixedly installed on one side of the semicircular block 2, and a drain port is provided on one side of the oil inlet box.

[0015] The technical effect of adopting the above-mentioned further solution is that the drain port can release the hydraulic oil inside the oil inlet box.

[0016] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0017] 1. In this embodiment of the invention, a water pump is started by an external power source. At this time, the water pump draws out the cooling water from inside the first coolant tank through the input pipe. The water pump outputs the cooling water to the inside of the output pipe. The output pipe is wrapped around the outer surface of the thick pipe to cool the hydraulic oil inside, thereby reducing the temperature of the inner wall of the thick pipe and cooling the hydraulic oil inside. The water that has cooled the inner wall of the thick pipe is transported to the inside of the second coolant tank through the cooling pipe. The temperature of the circulating cooling water in the second coolant tank is cooled by starting the cooler and reused. By turning the one-way valve, the cooled water in the second coolant tank enters the outer surface of the filter screen through the outlet pipe. The filter screen filters the water and reduces impurities brought into the internal pipes of the cooling water to prevent excessive impurities from clogging the pipes. After filtration, the water enters the collection box and then enters the first coolant tank for reuse.

[0018] 2. In this embodiment of the invention, by activating the electric push rod one to move the semicircular block two, the semicircular block two and the semicircular block pair squeeze the rubber hose. At the same time, the hydraulic oil inside the hydraulic oil tank enters the interior of the rubber hose through the thick pipe. When the rubber hose is squeezed, its hydraulic oil is squeezed into the interior of the outer tube through the oil outlet. Gas is ejected outward at the oil outlet, which pushes the block block to move to one side of the outer surface of the limit rod, thereby causing the block block to detach from the interior of the oil outlet. At this time, the hydraulic oil inside the rubber hose is squeezed into the interior of the outer tube through the oil outlet.

[0019] 3. In this embodiment of the invention, when the blocking block is not subjected to any external force, the spring limits the blocking block so that the blocking block is located on the outer surface of the oil outlet hole, blocking the oil outlet hole. When the rubber hose is squeezed and returns to its original state, it prevents the hydraulic oil inside the outer tube from being absorbed into the inside of the rubber hose through the oil outlet hole, and then enters the inside of the hydraulic cylinder through the oil inlet box to hydraulically power the hydraulic cylinder.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1 to 8This embodiment provides a technical solution: a high-pressure, high-flow hydraulic component with real-time temperature control of hydraulic oil, comprising: a base plate 101, a first coolant tank 102 fixedly mounted on the top of the base plate 101, a second coolant tank 103 fixedly mounted on the top of the base plate 101, a cooler 104 fixedly mounted on one side of the second coolant tank 103, a fixed U-shaped block 107 fixedly mounted on the bottom of the second coolant tank 103, and a cylinder 109 fixedly mounted on the bottom of the second coolant tank 103, with one end of the cylinder 109 fixedly mounted on... A movable U-shaped block 110 is installed, and a filter screen 108 is detachably connected to the opposite side of the movable U-shaped block 110 and the fixed U-shaped block 107. A liquid outlet pipe 105 is fixedly installed at the bottom of the coolant tank 2 103, and a one-way valve 106 is provided inside the liquid outlet pipe 105. A liquid collection box 111 is fixedly installed at the top of the coolant tank 1 102, and the liquid collection box 111 is located directly below the filter screen 108. An outer ring 116 is fixedly installed at the top of the base plate 101, and a thick pipe 117 is fixedly installed on the inner wall of the outer ring 116.

[0032] In use, the water pump 113 is started by an external power source. The water pump 113 then draws cooling water from the coolant tank 102 through the input pipe 114. The water pump 113 outputs the cooling water to the inside of the output pipe 115, which is wrapped around the outer surface of the thick pipe 117 to cool the hydraulic oil inside, thus lowering the temperature of the inner wall of the thick pipe 117. The water cooled from the inner wall of the thick pipe 117 is then transported to the inside of the second coolant tank 103 through the cooling pipe 131. The cooling water is then activated by starting the cooling system. After the coolant in the second coolant tank 103 is circulated, the coolant temperature is cooled and reused. By turning the one-way valve 106, the cooled coolant in the second coolant tank 103 enters the outer surface of the filter screen 108 through the outlet pipe 105. The filter screen filters the coolant and reduces impurities in the internal cooling water pipes to prevent excessive impurities from clogging the pipes. After filtration, the coolant enters the liquid collection box 111 and then enters the first coolant tank 102 for reuse.

[0033] like Figures 1 to 8 As shown, in one embodiment, a hydraulic oil tank 118 is fixedly installed on the top of the thick pipe 117, a water pump 113 is fixedly installed on one side of the coolant tank 102, an input pipe 114 is fixedly installed at the input end of the water pump 113, a cooling pipe 131 is fixedly installed at the output end of the water pump 113, an output pipe 115 is located on the inner wall of the outer ring 116, and a cooling pipe 131 is fixedly installed at one end of the output pipe 115. Water cooled by the inner wall of the thick pipe 117 is transported to the inside of the coolant tank 103 through the cooling pipe 131. The temperature of the circulating coolant inside the coolant tank 103 is cooled by starting the cooler 104 so that it can be used again.

[0034] like Figures 1 to 8 As shown, in one embodiment, one end of the cooling pipe 131 is fixedly installed on the inner wall of the coolant tank 103. A rubber hose 119 is fixedly installed on one side of the thick pipe 117, and an outer pipe 123 is fixedly installed on one side of the rubber hose 119. An oil outlet 127 is opened on one side of the rubber hose 119, and multiple limiting rods 124 are fixedly installed on one side of the rubber hose 119. A blocking block 126 is movably sleeved on the outer surface of the multiple limiting rods 124. A spring 125 is fixedly installed on one side of the blocking block 126. The hydraulic oil inside the rubber hose 119 is squeezed into the interior of the outer pipe 123 through the oil outlet 127. When the blocking block 126 is not subjected to any external force, the spring 125 limits the blocking block 126, so that the blocking block 126 is located on the outer surface of the oil outlet 127, blocking the oil outlet 127. When the rubber hose 119 is squeezed and returns to its original state, it prevents the hydraulic oil inside the outer pipe 123 from being absorbed into the interior of the rubber hose 119 through the oil outlet 127.

[0035] like Figures 1 to 8 As shown, in one embodiment, the blocking block 126 is located inside the oil outlet 127 and the outer tube 123. A temperature detector 128 is provided inside the outer tube 123. An oil inlet box 129 is fixedly installed on one side of the outer tube 123. A hydraulic cylinder 130 is fixedly installed on one side of the oil inlet box 129. A semi-circular block 121 is provided on the outer surface of the rubber hose 119. The temperature detector 128 is used to detect the temperature of the hydraulic oil inside the outer tube 123.

[0036] like Figures 1 to 8 As shown, in one embodiment, a semi-circular block 122 is provided on the outer surface of the rubber hose 119. An electric push rod 120 is fixedly installed on one side of the semi-circular block 122. A drain port 1291 is provided on one side of the oil inlet box 129, which can release the hydraulic oil inside the oil inlet box 129.

[0037] Working principle: During use, the electric push rod 120 is activated, which moves the semicircular block 122, causing it to squeeze the rubber hose 119 along with the semicircular block 121. At this time, the hydraulic oil inside the hydraulic tank 118 enters the rubber hose 119 through the thick pipe 117. When the rubber hose 119 is squeezed, the hydraulic oil is forced into the outer pipe 123 through the oil outlet 127. Gas is ejected from the oil outlet 127, pushing the blocking block 126 to one side of the outer surface of the limit rod 124, thus causing the blocking block 126 to exit through the oil outlet 127. When the inner part of the rubber hose 119 is detached, the hydraulic oil inside the rubber hose 119 is squeezed into the inner part of the outer tube 123 through the oil outlet 127. When the blocking block 126 is not subjected to any external force, the spring 125 limits the blocking block 126, so that the blocking block 126 is located on the outer surface of the oil outlet 127, blocking the oil outlet 127. When the rubber hose 119 returns to its original state after being squeezed, it prevents the hydraulic oil inside the outer tube 123 from being absorbed into the inner part of the rubber hose 119 through the oil outlet 127, and then enters the inner part of the hydraulic cylinder 130 through the oil inlet box 129 to hydraulically power the hydraulic cylinder 130. When hydraulic oil enters the outer pipe 123, the temperature detector 128 detects its temperature. When the hydraulic oil temperature is too high, the water pump 113 is started by an external power source. At this time, the water pump 113 draws cooling water from the coolant tank 102 through the input pipe 114. The water pump 113 outputs the cooling water to the inside of the output pipe 115. The output pipe 115 is wrapped around the outer surface of the thick pipe 117 to cool the hydraulic oil inside, thereby reducing the temperature of the inner wall of the thick pipe 117 and cooling the hydraulic oil inside. The water that has cooled the inner wall of the thick pipe 117 flows through the cooling pipe 131. The cooled water is transported to the interior of coolant tank 2 103. The circulated coolant inside coolant tank 2 103 is cooled by starting cooler 104 and reused. By turning check valve 106, the cooled water inside coolant tank 2 103 enters the outer surface of filter screen 108 through outlet pipe 105. The filter screen filters the water, reducing impurities brought into the internal pipes of the coolant to prevent excessive impurities from clogging the pipes. After filtration, the water enters the liquid collection box 111 and then enters the interior of coolant tank 1 102 for reuse.
