Technical Field
[0001] This utility model belongs to the field of hydraulic pump station technology, specifically relating to a heat dissipation structure for an easy-to-maintain hydraulic pump station. Background Technology
[0002] In industrial production and the operation of various mechanical equipment, hydraulic pump stations, as core power sources and control components, play a crucial role in providing stable pressure and flow to the hydraulic system. During continuous operation, the hydraulic oil generates a significant amount of heat due to mechanical friction and energy conversion. Currently, oil coolers are a common and effective heat dissipation device in the heat dissipation design of hydraulic pump stations, as disclosed in existing patent CN220060126U, "A heat dissipation structure for a hydraulic pump station." This heat dissipation structure includes a hydraulic pump station and a heat dissipation box mounted on top of the hydraulic pump station. Oil inlet pipes and oil outlet pipes are fixedly installed on the outer walls on both sides. Two heat dissipation fins are fixedly installed inside the heat dissipation box, and a connecting coil is provided between the two heat dissipation fins. One end of the oil inlet pipe extends into the heat dissipation box and is fixedly connected to one end of the connecting coil. Typically, this type of oil cooler is installed above the hydraulic pump station. Its working principle is to allow high-temperature hydraulic oil to enter the pipes inside the oil cooler. At the same time, the forced airflow generated by the fan allows the hydraulic oil to exchange heat with the outside air, thereby achieving the effect of cooling and heat dissipation. This heat dissipation method can meet the heat dissipation requirements of the hydraulic pump station to a certain extent and ensure its normal operation.
[0003] Existing hydraulic pump station oil cooler heat dissipation structures typically have protective mesh plates installed on both sides to prevent external debris and dust from entering the oil cooler and causing damage to the heat dissipation pipes and fans or affecting the heat dissipation effect. However, the disassembly and assembly methods of the protective mesh plates on existing oil cooler heat dissipation structures are mostly cumbersome. The common installation method may be bolt fastening. When it is necessary to remove the protective mesh plates to inspect and maintain the inside of the oil cooler, the operator needs to spend a lot of time and effort to disassemble and install these fastening components, which is inconvenient for the operator to inspect and maintain the oil cooler heat dissipation structure. Therefore, this utility model proposes a heat dissipation structure for hydraulic pump stations that is easy to maintain. Utility Model Content
[0004] The purpose of this invention is to provide a heat dissipation structure for a hydraulic pump station that is easy to maintain, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat dissipation structure for an easy-to-maintain hydraulic pump station, comprising an oil cooler installed on the top of the main body of the hydraulic pump station, an oil inlet pipe and an oil outlet pipe respectively provided on both sides of the oil cooler, two air inlets and outlets communicating with the interior of the oil cooler on both the front and rear surfaces of the oil cooler, two top plates installed on the top surface of the oil cooler, and two bottom-inserted protective mesh plates adapted to the air inlets and outlets fixed at the bottom of each top plate, and a strip plate slot communicating with the top surface of the oil cooler is provided through the top inner wall of the air inlet and outlet, and the bottom-inserted protective mesh plates are inserted into the inner side of the air inlet and outlet through the strip plate slot;
[0006] The oil cooler is equipped with a quick-closing structure at the top center to press and limit the two top plates.
[0007] Preferably, the quick-release limiting structure includes a central base fixed at the center of the top of the oil cooler, a cylindrical top rod fixed on the top surface of the central base, a limiting pressure plate movably sleeved on the surface of the cylindrical top rod, a circular end plate fixed on the top surface of the cylindrical top rod, and a spring sleeved on the top surface of the cylindrical top rod and located between the circular end plate and the limiting pressure plate, wherein the two ends of the limiting pressure plate press against the top of the two top plates respectively.
[0008] Preferably, the center of the limiting pressure plate is provided with a circular hole that is adapted to the cylindrical top rod.
[0009] Preferably, the bottom end of the spring abuts against the top surface of the limiting pressure plate, and the top end of the spring abuts against the bottom surface of the circular end plate.
[0010] Preferably, the top surface of the top plate has two symmetrically fixed protrusions, and the end of the limiting pressure plate is located between the two protrusions.
[0011] Preferably, handles are fixed to the top of both ends of the limiting pressure plate, and the handles are U-shaped.
[0012] Preferably, a rubber inner base strip is embedded in the inner wall of the strip plate insertion port, and the side of the rubber inner base strip is provided with a sealing strip that abuts against the lower insert protective mesh plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model improves the heat dissipation structure of the oil cooler on the existing hydraulic pump station by designing the protective mesh plate as a bottom-insertion installation method and fixing a top plate above the two protective mesh plates. Then, a quick-limiting structure is designed on the top of the oil cooler, which can quickly complete the disassembly and assembly of the protective mesh plate. This makes it convenient for subsequent operators to quickly remove the protective mesh plate for maintenance, facilitates the inspection and maintenance of the internal parts of the heat dissipation oil cooler, and improves the convenience of later maintenance of the entire heat dissipation structure.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example 1
[0023] Please see Figures 1 to 4This is the first embodiment of the present invention, which provides a technical solution: a heat dissipation structure for an easy-to-maintain hydraulic pump station, including an oil cooler 1 installed on the top of the hydraulic pump station body 8. An oil inlet pipe 6 and an oil outlet pipe 7 are respectively provided on both sides of the oil cooler 1, and are connected to the hydraulic oil circuit of the hydraulic pump station body 8. This allows the hydraulic oil in the hydraulic system of the hydraulic pump station body 8 to enter the manifold inside the oil cooler 1 through the oil inlet pipe 6, and then be discharged back into the hydraulic oil circuit of the hydraulic pump station body 8 through the oil outlet pipe 7. During this process, the cooling fan inside the oil cooler 1 continuously cools the manifold inside the oil cooler 1, thereby dissipating heat and cooling the hydraulic oil as it passes through the manifold inside the oil cooler 1. The above structural principles are all well-known in the prior art. For details of the technology, please refer to the existing patent with publication number CN220060126U. It will not be elaborated here. The front and rear surfaces of the oil cooler 1 are provided with two air inlets and outlets 2 that communicate with the interior of the oil cooler 1, so that air can enter and exit when the internal cooling fan of the oil cooler 1 is running. Two top plates 3 are installed on the top surface of the oil cooler 1, and two bottom-inserted protective mesh plates 4 that are adapted to the air inlets and outlets 2 are fixed at the bottom of each top plate 3. The top inner wall of the air inlet and outlet 2 is provided with a strip plate inlet 11 that communicates with the top surface of the oil cooler 1. The bottom-inserted protective mesh plates 4 are inserted into the inside of the air inlet and outlet 2 through the strip plate inlet 11. The mesh structure of the bottom-inserted protective mesh plates 4 can prevent foreign objects from entering the interior of the oil cooler 1 and causing damage without affecting the normal air entry and exit.
[0024] The top center of the oil cooler 1 is equipped with a quick-closing structure 5 that presses and limits the two top plates 3. This allows for quick pressing and limiting of the top plates 3. The limit on the top plates 3 can also be quickly released by hand. Then, the operator can lift the top plates 3 and remove the bottom-inserted protective mesh plate 4 from the top of the oil cooler 1, which facilitates subsequent cleaning and maintenance.
[0025] In this embodiment, preferably, the quick-release limiting structure 5 includes a central base 51 welded and fixed to the center of the top of the oil cooler 1, a cylindrical top rod 53 fixed to the top surface of the central base 51, a limiting pressure plate 52 movably sleeved on the surface of the cylindrical top rod 53, a circular end plate 55 fixed to the top surface of the cylindrical top rod 53, and a spring 54 sleeved on the top surface of the cylindrical top rod 53 and located between the circular end plate 55 and the limiting pressure plate 52. The two ends of the limiting pressure plate 52 press against the tops of the two top plates 3 respectively, which can press and limit the two top plates 3 during daily use to ensure the installation stability of the bottom-inserted protective mesh plate 4. If the bottom-inserted protective mesh plate 4 needs to be quickly released later... When quickly disassembling the oil cooler 1 for cleaning and maintenance, simply lift the limiting pressure plate 52 so that it moves up on the surface of the cylindrical top rod 53, causing the spring 54 to be gradually compressed. This prevents the end of the limiting pressure plate 52 from pressing the top plate 3 tightly. Then, rotate the limiting pressure plate 52 ninety degrees so that both ends of the limiting pressure plate 52 can be rotated away from the top of the two top plates 3, thus quickly releasing the limiting effect on the top plate 3. At this point, lifting the top plate 3 allows for quick removal of the lower insert protective mesh plate 4, facilitating subsequent cleaning and maintenance. This solves the problem of cumbersome disassembly and assembly of the protective mesh in the existing hydraulic pump station heat dissipation structure, which leads to low convenience of later maintenance.
[0026] In this embodiment, preferably, a circular hole adapted to the cylindrical top rod 53 is provided through the center of the limiting pressure plate 52, so that the limiting pressure plate 52 can move up and down on the surface of the cylindrical top rod 53 and can also rotate.
[0027] In this embodiment, preferably, the bottom end of the spring 54 abuts against the top surface of the limiting pressure plate 52, and the top end of the spring 54 abuts against the bottom surface of the circular end plate 55. Under the pushing of the spring 54, the limiting pressure plate 52 can stably press the top plate 3 during daily use, ensuring the installation stability of the top plate 3 and the bottom insert protective mesh plate 4.
[0028] In this embodiment, preferably, two protrusions 56 are symmetrically welded and fixed on the top surface of the top plate 3, and the end of the limiting pressure plate 52 is located between the two protrusions 56. Under the action of the protrusions 56, the limiting pressure plate 52 can be limited in the horizontal direction, so that the end of the limiting pressure plate 52 will not rotate on its own after pressing on the top surface of the top plate 3, further improving the pressing stability of the limiting pressure plate 52 on the top plate 3.
[0029] In this embodiment, preferably, handles 57 are welded and fixed to the top of both ends of the limiting pressure plate 52, and the handles 57 are U-shaped to facilitate the subsequent lifting and rotation of the limiting pressure plate 52 by the operator.
[0030] Example 2
[0031] Please see Figures 1 to 5This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, except that a rubber inner base strip 12 is embedded in the inner wall of the strip plate insertion port 11, and a sealing strip 13 is provided on the side of the rubber inner base strip 12 to abut against the lower insert protective mesh plate 4. Both the rubber inner base strip 12 and the sealing strip 13 are made of rubber material, and will undergo elastic deformation when squeezed. After the sealing strip 13 abuts against the lower insert protective mesh plate 4, it can play a certain sealing role.
[0032] In this embodiment, preferably, the sealing strip 13 and the rubber inner base strip 12 are an integral structure, and the cross-section of the sealing strip 13 is semi-circular.
[0033] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
