Description

Technical Field

[0001] This utility model relates to the field of hydraulic equipment technology, and in particular to a hydraulic station device with a heat dissipation circulation structure. Background Technology

[0002] A hydraulic power unit is the power unit in a hydraulic transmission system. It provides hydraulic oil with a certain pressure and flow rate to the entire system. During the operation of the hydraulic power unit, the hydraulic pump and valve components inevitably generate energy loss during energy conversion and transmission. Most of these losses are converted into heat. At the same time, the hydraulic oil also generates heat due to friction and pressure changes when flowing at high speed and throttling in the pipeline. This heat will quickly accumulate in the hydraulic oil in the oil tank, causing the oil temperature to rise.

[0003] Excessive oil temperature can lead to a series of problems, such as a significant decrease in hydraulic oil viscosity, increasing internal and external leakage; reduced lubrication performance, accelerating wear on moving parts; and aging and hardening of seals, causing them to lose their sealing effect. This severely impacts the stable operation and lifespan of the hydraulic system. Existing hydraulic power units typically rely on natural heat dissipation from the oil tank itself, or simply use a fan installed next to the tank for basic air cooling. Under high loads, prolonged continuous operation, or high ambient temperatures, this cooling method is inefficient, making it difficult to control the oil temperature within the ideal operating range, resulting in large temperature fluctuations and poor system stability.

[0004] Therefore, this utility model proposes a hydraulic station device with a heat dissipation circulation structure to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems of low heat dissipation efficiency leading to unstable oil temperature, and difficult filter maintenance requiring disassembly of pipelines for cleaning, which are common in existing hydraulic power station devices with heat dissipation circulation structures, this utility model aims to provide a hydraulic power station device with a heat dissipation circulation structure that has been improved and can effectively solve the above problems.

[0006] This utility model provides a hydraulic station device with a heat dissipation circulation structure, including: an oil tank, an oil return pipe entering the oil tank, a filter pipe; and a cooling pipe, a heat exchange box, a water pump, and a quick-release mechanism installed in the oil tank.

[0007] The cooling pipe is equipped with a water storage tank 2, which is used to hold cooling water to cool the oil returning from the return oil pipe.

[0008] Furthermore, the heat exchange box is located outside the oil tank, and a water storage tank is provided inside it; the water storage tank of the water pump and cooling pipe is connected to the water storage tank of the heat exchange box through a pipeline system to form a closed circulating heat dissipation loop; the quick-release mechanism is used to detachably fix a plug for sealing the filter tube, thereby realizing the quick opening and closing of the filter tube.

[0009] Preferably, the heat exchanger box is equipped with a partition that divides the water storage tank into a hot water zone for water inlet and a cold water zone for water outlet. A notch is provided at the bottom of the partition to connect the hot water zone and the cold water zone. The device also includes a fan that is positioned facing the hot water zone of the water storage tank to accelerate the cooling process of the cooling water in the zone through forced air cooling.

[0010] Preferably, a one-way valve is installed on the pipeline used to transport hot water between the second water storage tank and the first water storage tank. Its function is to ensure that the cooling water can only flow from the cooling pipe to the heat exchange box in one direction, so as to prevent the water that has been cooled or is being cooled in the heat exchange box from flowing back, thus ensuring the directionality and efficiency of the circulation.

[0011] Furthermore, as a specific implementation, the pipeline connecting the second water storage tank and the first water storage tank includes a second pipe leading out from the second water storage tank and a first pipe connected to the first water storage tank, and the one-way valve is connected in series between the second pipe and the first pipe.

[0012] Preferably, the quick-release mechanism includes a connecting plate fixed to or near the oil tank, a limiting plate slidably mounted on the connecting plate, and a pin; the pin is used to detachably insert the limiting plate and the plug simultaneously, and the plug and the limiting plate can be quickly locked or unlocked by inserting and pulling.

[0013] Furthermore, a positioning post is fixed on the limiting plate, and a through hole is provided on the positioning post; a corresponding positioning hole three is provided on the plug body; and a positioning hole two is provided on the connecting plate; when the locking operation is performed, the pin will pass through the positioning hole two of the connecting plate, the through hole of the positioning post, and the positioning hole three of the plug body in sequence to form a reliable mechanical locking structure.

[0014] As a specific guiding structure, the connecting plate is also provided with a positioning hole. The positioning pin of the limiting plate can be slidably inserted into the positioning hole. This fit provides a clear movement trajectory and stable guidance for the up and down sliding of the limiting plate, ensuring smooth operation.

[0015] Preferably, the lower part of the plug is formed into a columnar body that can be tightly inserted into the top opening of the filter tube. This insertion method can effectively seal the internal space of the filter tube, preventing contaminants from entering and hydraulic oil from leaking.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model, by setting up a water-cooled circulating heat dissipation circuit consisting of a cooling pipe, a second water storage tank, a heat exchange box, a first water storage tank, a water pump, a fan, and pipelines, continuously cools the high-temperature hydraulic oil in the return oil pipe by combining natural convection and forced circulation of water. This solves the problems of low heat dissipation efficiency and unstable oil temperature in existing hydraulic station devices, and achieves the technical effect of efficient circulating heat dissipation and improved oil temperature stability.

[0018] 2. This utility model, by setting up a quick-release mechanism consisting of a connecting plate, a limiting plate, a positioning post, a plug, a pin, and a corresponding hole system, realizes the quick locking and unlocking of the plug at the top of the filter tube. It solves the problems of difficult maintenance of existing filters, the need to disassemble the pipeline, and cumbersome operation, and achieves the technical effect of quickly cleaning the filter tube without disassembling the pipeline, significantly improving maintenance efficiency and practicality.

[0027] Example:

[0028] Please refer to Figures 1 to 5 A hydraulic station device with a heat dissipation circulation structure includes an oil tank 1, a return oil pipe 12 entering the oil tank 1, and a filter pipe 201. The oil tank 1 is used to store hydraulic oil. The device also includes a cooling pipe 3 disposed inside the oil tank 1, adjacent to the return oil pipe 12, for cooling the oil in the return oil pipe 12. The device also includes a heat exchange box 5 and a water pump 4 disposed outside the oil tank 1. The cooling pipe 3, water pump 4, and heat exchange box 5 are connected via a piping system to form a circulating heat dissipation circuit. The device also includes a quick-release mechanism 2, which is installed on the top of the filter pipe 201 for detachably fixing a plug 205 used to seal the filter pipe 201.

[0029] Please refer to Figure 3 The heat exchange box 5 is equipped with a partition 7, which divides the water storage tank 6 into a hot water zone for water inlet and a cold water zone for water outlet. The bottom of the partition 7 has a notch for connecting the hot water zone and the cold water zone. A fan 11 is also fixedly connected to one side of the heat exchange box 5. The fan 11 is positioned directly opposite the hot water zone of the water storage tank 6 and is used to provide forced air cooling for the cooling water in the hot water zone.

[0030] Please refer to Figure 1 The water storage tank 13 of the cooling pipe 3 is connected to the water storage tank 6 of the heat exchange box 5 by a pipeline. The pipeline includes a pipe 10 leading out from the water storage tank 13 and a pipe 8 connected to the water storage tank 6. A one-way valve 9 is connected in series between the pipe 10 and the pipe 8. The one-way valve 9 is used to prevent water in the water storage tank 6 from flowing back to the water storage tank 13.

[0031] Please refer to Figure 4 and Figure 5 The quick-release mechanism 2 specifically includes a connecting plate 202 fixed to the oil tank (1) or its vicinity, and a limiting plate 209 that can be slidably mounted on the connecting plate 202; the quick-release mechanism 2 also includes a pin 210.

[0032] Reference Figure 4 The lower part of the plug 205 forms a columnar body that can be inserted into the top opening of the filter tube 201 to achieve a seal on the filter tube 201.

[0033] Reference Figure 4 and Figure 5 A positioning post 208 is fixed on the limiting plate 209, and a through hole 207 is provided on the positioning post 208; a positioning hole 206 is provided on the plug body 205; a positioning hole 204 and a positioning hole 203 serving as a guide structure are provided on the connecting plate 202; the positioning post 208 is slidably inserted into the positioning hole 203 to guide the sliding of the limiting plate 209; when the pin 210 is in the locked position, it passes through the positioning hole 204, the through hole 207 and the positioning hole 206 in sequence to lock the plug body 205 and the limiting plate 209.

[0034] Working principle: When oil returns to oil tank 1 from oil return pipe 12, the water storage tank 13 in cooling pipe 3 will cool the oil. When the water temperature rises, the hot water after heat exchange with oil return pipe 12 will float upward due to its lower density and flow out from pipe 10. After passing through check valve 9, it flows into the right side of water storage tank 6 in heat exchange box 5 through pipe 8. Check valve 9 makes the water flow downward. The left side of water storage tank 6 is the cold water area, and the right side of water storage tank 6 is the hot water area. The fan 11 is started to cool the water on the right side of water storage tank 6. Due to the action of baffle 7, the water will move downward due to its lower density after cooling and flow into the left side of water storage tank 6 through the gap in the middle of the inner wall of water storage tank 6 at the bottom of baffle 7. Then the water pump 4 is started to pump the cold water into water storage tank 13, thereby playing the role of circulating heat dissipation for hydraulic station device, improving heat dissipation efficiency, improving oil temperature stability, and improving practicality.

[0035] First, pull the pin 210 out of the positioning hole 204 in the quick-release mechanism 2, so that it slides out of the positioning hole 206 and the through hole 207 at the same time, releasing the restriction on the plug 205 and the positioning post 208. Then, move the limiting plate 209 upward, and the limiting plate 209 drives the through hole 207 to slide out along the positioning hole 203. The connecting plate 202 provides a fixed position for the positioning hole 204 and the positioning hole 203, so that the plug 205 leaves the filter tube 201. Then, the notch at the top of the filter tube 201 caused by the removal of the plug 205 can be flushed, so that the inside of the filter tube 201 can be flushed. After flushing, the filter tube 201 can be reinstalled, thus achieving the function of quick disassembly of the plunger. Cleaning can be done without disassembling the pipe, improving maintenance efficiency and increasing practicality.
