Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic transmission equipment, and in particular to a hydraulic pump station. Background Art

[0002] The hydraulic station, also known as the hydraulic pump station, is an independent hydraulic device. It supplies oil according to the requirements of the main engine and controls the direction, pressure and flow of the oil flow. Its working principle is as follows: the motor drives the oil pump to rotate, and the oil pump sucks oil from the oil tank and then pumps oil, converting mechanical energy into the pressure energy of the hydraulic oil. The hydraulic oil is adjusted in direction, pressure and flow through the integrated block (or valve combination) and then transmitted to the oil cylinder or oil motor of the hydraulic machinery through the external pipeline, thereby controlling the change of direction, force and speed of the hydraulic machinery, and then driving the hydraulic machinery to do work.

[0003] Since hydraulic oil is generally circulated and the oil temperature rises rapidly after a period of continuous operation, the hydraulic pump station needs to stop working once the oil temperature rises to a certain temperature. In order to ensure the working efficiency of the hydraulic pump station, a circulating water pipe is used in the pump station to cool down the oil. In order to expand the cooling area, the circulating water pipe is also connected to multiple cooling fins. However, there is a certain water pressure in the circulating water pipe. The water in the cooling fins is affected by the water pressure, resulting in a slow circulation speed of the water in the cooling fins, which affects the cooling of the oil. Summary of the invention

[0004] The present invention is intended to provide a hydraulic pump station to solve the problem of slow water circulation speed in heat dissipation fins in the prior art.

[0005] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a hydraulic pump station, comprising a pump station, the pump station is connected to a cooling water tank, the cooling water tank is connected to a water pump, the water pump is connected to an L-shaped cooling pipe located in the pump station, the L-shaped cooling pipe comprises a vertical pipe and a transverse pipe, the top of the transverse pipe is connected to a heat dissipation fin with a hollow interior, a driving rod is provided in the transverse pipe, one end of the driving rod is connected to a motor for driving the rotation thereof, the other end of the driving rod is connected to a sealing plate for sealing the heat dissipation fin, the sealing plate is connected to a drainage pipe inclined downward toward the bottom wall of the transverse pipe, and the drainage pipe is connected to the bottom of the heat dissipation fin.

[0006] The working principle of the present invention is as follows: the water pump draws the water in the cooling water tank into the vertical pipe and the horizontal pipe, and the water then flows into the radiating fins. The water in the radiating fins absorbs heat and heats up. At this time, the motor rotates the driving rod, and the sealing plate connected to the connecting pipe seals the bottom of the radiating fin. The water in the radiating fin flows downward through the drainage pipe. When the sealing plate does not seal the radiating fins, the water enters the radiating fins again, realizing the circulation of water in the radiating fins.

[0007] The beneficial effects of the present invention are as follows: since the water in the transverse tube has a certain pressure, the water in the transverse tube will block the circulation of water in the heat sink fins, thereby causing the cooling effect of the heat sink fins to deteriorate. For this reason, the driving rod is driven to rotate by a motor, and the sealing plate seals the heat sink fins. The water in the heat sink fins flows downward through the drainage pipe. When the sealing plate does not seal the heat sink fins, the water enters the heat sink fins again, accelerating the circulation of water in the heat sink fins and improving the cooling effect of the heat sink fins.

[0008] Furthermore, a connecting pipe is connected between the vertical pipe and the top of the radiating fin. Water in the vertical pipe flows into the radiating fin through the connecting pipe, which can speed up the circulation speed of the water in the radiating fin and improve the cooling efficiency of the radiating fin.

[0009] Furthermore, the motor is connected to an angle sensor, which is a commonly used control component that can control the rotation angle of the drive rod so that the sealing sheet can seal the heat dissipation fins.

[0010] Furthermore, the number of the heat dissipation fins is multiple. By providing multiple heat dissipation fins, the cooling of the hydraulic oil can be accelerated.

[0011] Furthermore, the drainage pipe is provided with a one-way valve that is open to the outside thereof. The one-way valve can limit the flow direction of water in the drainage pipe so that the water in the transverse pipe will not affect it.

[0012] Furthermore, the heat dissipation fin is in a triangular shape. The triangular heat dissipation fin has a large surface area, which can increase the cooling area of ​​the hydraulic oil and accelerate the cooling of the hydraulic oil.

[0013] Furthermore, the cooling water tank is provided with an observation window, through which the liquid level in the cooling water tank can be observed, so as to facilitate timely addition of water.

[0014] Furthermore, the cooling water tank is filled with coolant, which can continuously cool the cooling water tank to ensure the cooling effect of water. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following is further described in detail through specific implementation methods:

[0018] The figure marks in the drawings of the specification include: pipeline 1, cooling water tank 2, water pump 3, cooling water pipe 4, vertical pipe 5, connecting pipe 6, pump station 7, transverse pipe 8, driving rod 9, motor 10, drainage pipe 11, cooling fin 12, connecting plate 13, sealing plate 14.

[0019] The embodiment is basically as shown in the attached Figure 1 and attached Figure 2 As shown, a hydraulic pump station includes a pump station 7 and a cooling water tank 2. The cooling water tank 2 is provided with an observation window. The right side of the cooling water tank 2 is connected to a water pump 3. The water pump 3 is connected to a cooling water pipe 4. The right side of the cooling water pipe 4 extends into the pump station 7 and is welded with an L-shaped pipe. The L-shaped pipe includes a vertical pipe 5 and a transverse pipe 8. The left side of the transverse pipe 8 is welded and connected to the bottom of the vertical pipe 5. The right side of the transverse pipe 8 is welded with a pipe 1 connected to the cooling water tank 2.

[0020] The top of the transverse tube 8 is welded and connected with a heat dissipation fin 12 with a hollow interior. The heat dissipation fin 12 is in the shape of a triangle. The tops of the vertical tube 5 and the heat dissipation fin 12 are welded and connected with a connecting tube 6. A motor 10 is provided on the right side of the pump station 7. The motor 10 is rotatably connected with a driving rod 9 extending into the transverse tube 8. The connection between the driving rod 9 and the transverse tube 8 is filled with a rubber sheet. The driving rod 9 is welded with a connecting plate 13. The connecting plate 13 is welded with an arc-shaped sealing plate 14. The outer wall of the sealing plate 14 abuts against the inner wall of the transverse tube 8. The sealing plate 14 is also welded and connected with a drainage tube 11 that is tilted downward toward the bottom inner wall of the transverse tube 8.

[0021] The water pump 3 pumps the water in the cooling water tank 2 into the vertical pipe 5 and the horizontal pipe 8, and the water flows into the radiating fins 12 through the connecting pipe 6. The water in the radiating fins 12 absorbs heat and heats up. Since the water in the horizontal pipe 8 has a certain pressure, the water pressure in the horizontal pipe 8 will prevent the water in the radiating fins 12 from flowing into the horizontal pipe 8. At this time, the motor 10 rotates the driving rod 9, and the driving rod 9 drives the sealing plate 14 to rotate through the connecting plate 13. The sealing plate 14 seals the bottom of the radiating fins 12, and the top of the drainage pipe 11 is connected to the radiating fins 12. The water in the radiating fins 12 flows downward through the drainage pipe 11, realizing the circulation of the water in the radiating fins 12.

[0022] Preferably, a one-way valve that is open to the outside of the drainage pipe 11 is welded inside the drainage pipe 11. The one-way valve can limit the flow direction of water in the drainage pipe 11 so that the water in the transverse pipe 8 will not affect it.

[0023] It should be pointed out that for those skilled in the art, multiple variations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The protection scope required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
