Description

Technical Field

[0001] This utility model relates to the field of hydraulic gear pump technology, specifically a dustproof and heat-dissipating hydraulic gear pump. Background Technology

[0002] A gear pump is a rotary pump that transports or pressurizes liquids by relying on the change and movement of the working volume formed between the pump cylinder and meshing gears. The hydraulic gear pump is the heart of a hydraulic system, often simply called an oil pump. A hydraulic gear pump is an energy conversion device; its function is to induce motion in flow, converting mechanical energy into fluid energy. The pump is the power component in a hydraulic transmission system, driven by a prime mover. It extracts mechanical energy from the prime mover's output power and converts it into the pressure energy of the fluid, providing pressurized hydraulic fluid to the system.

[0003] A search revealed that patent document CN219888260U discloses a dustproof and heat-dissipating hydraulic gear pump, comprising a hydraulic gear pump body, an mounting plate fixedly mounted on the surface of the hydraulic gear pump body, a protective shell fixedly mounted on one side of the mounting plate, dustproof mechanisms mounted on both sides of the protective shell, a heat dissipation mechanism fixedly mounted on one side of the protective shell, a dustproof net mounted on one side of the heat dissipation mechanism, and a dustproof cover installed inside the protective shell.

[0004] The hydraulic gear pump is dustproof by adding a protective shell to the outside of the pump body. However, the presence of the protective shell increases the thickness of the gear pump housing and is not conducive to air circulation around the hydraulic gear pump, resulting in poor heat dissipation and affecting the use of the hydraulic gear pump. Therefore, a dustproof and heat-dissipating hydraulic gear pump is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a dustproof and heat-dissipating hydraulic gear pump, which has advantages such as good dustproof and heat dissipation effects. It solves the problem that existing hydraulic gear pumps use an additional protective shell on the outside of the pump body for dust prevention, but the presence of the protective shell increases the thickness of the gear pump housing and is not conducive to air circulation around the hydraulic gear pump, resulting in poor heat dissipation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a dustproof and heat-dissipating hydraulic gear pump, comprising a hydraulic gear pump and a heat dissipation cover fixedly installed on the outside of the hydraulic gear pump, wherein the heat dissipation cover communicates with the interior of the hydraulic gear pump, a heat dissipation component is provided on the upper side of the heat dissipation cover, and a dustproof component is provided on the heat dissipation cover.

[0007] The heat dissipation assembly includes a fixing plate fixedly connected to the outer wall of the hydraulic gear pump, two mounting plates fixedly connected to the outer side of the fixing plate, and a cooling fan fixedly mounted on the top of the two mounting plates.

[0008] The dustproof assembly includes an air inlet mesh fixedly connected to the side of the heat sink and an exhaust mesh fixedly connected to the top of the heat sink. A first dustproof plate is provided on the outer side of the air inlet mesh. The end of the first dustproof plate away from the hydraulic gear pump is movably hinged to the heat sink. A limit component is provided between the first dustproof plate and the hydraulic gear pump. A second dustproof plate is provided on the upper side of the exhaust mesh. The second dustproof plate is slidably installed between the two fixed plates.

[0009] Furthermore, the mounting plate has threaded holes on its inner side, and the cooling fan is mounted on the outer side of the mounting plate by fixing screws, with the air inlet of the cooling fan corresponding to the air outlet.

[0010] Furthermore, the number of the limiting components is set to two sets, with the two sets of limiting components located on the upper and lower sides of the first dustproof plate, respectively.

[0011] Furthermore, the limiting component includes a connecting piece fixedly connected to the outer wall of the first dustproof plate and a fixed box fixedly connected to the outside of the hydraulic gear pump. The fixed box is provided with a limiting rod extending through it from top to bottom. One end of the limiting rod extends to the inner side of the connecting piece, and a pull head is fixedly connected to the end of the limiting rod away from the connecting piece.

[0012] Furthermore, the inner side of the connecting piece is provided with a through hole that matches the limiting rod. The inside of the fixing box is respectively provided with a spring and a support plate. The spring is sleeved on the outer wall of the limiting rod, and the support plate is fixedly connected to the outer wall of the limiting rod. The support plate is located at one end of the spring corresponding to the connecting piece, and the end of the spring away from the support plate abuts against the inner wall of the fixing box.

[0013] Furthermore, a sliding groove is provided on the inner side of the mounting plate, and a slider that slides with the second dustproof plate is provided near the sliding groove. The side of the sliding groove away from the fixed plate does not penetrate through it.

[0014] Furthermore, a positioning plate is fixedly connected to the end of the second dustproof plate away from the fixed plate, a magnetic block is provided at the end of the mounting plate, and a magnetic sheet is provided on the positioning plate at the position corresponding to the magnetic block.

[0015] Compared with the prior art, the present invention provides a dustproof and heat-dissipating hydraulic gear pump, which has the following beneficial effects:

[0016] This dustproof and heat-dissipating hydraulic gear pump features a unique design. During operation, opening the first dustproof plate allows external air to flow through the air inlet mesh into the heat dissipation shroud. Simultaneously, opening the second dustproof plate aligns the exhaust mesh with the cooling fan. The combined effect of the heat dissipation shroud, air inlet mesh, exhaust mesh, and cooling fan enhances airflow around the hydraulic gear pump, facilitating rapid heat removal and improving cooling efficiency. When the pump is not in use, the first and second dustproof plates are reset. The first dustproof plate protects the air inlet mesh, and the second dustproof plate protects the exhaust mesh, providing stable dust protection. This design ensures efficient heat dissipation during operation and stable dust protection after use, resulting in high practicality and extended service life. Attached Figure Description

[0024] 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.

[0025] Please see Figures 1 to 6 The dustproof and heat-dissipating hydraulic gear pump in this embodiment includes a hydraulic gear pump 1 and a heat sink 2 fixedly installed on the outside of the hydraulic gear pump 1. The heat sink 2 communicates with the inside of the hydraulic gear pump 1. A heat dissipation component is provided on the upper side of the heat sink 2. The heat dissipation component includes a fixing plate 5 fixedly connected to the outer wall of the hydraulic gear pump 1. Two mounting plates 6 are fixedly connected to the outside of the fixing plate 5. A cooling fan 7 is fixedly installed on the top of the two mounting plates 6.

[0026] The mounting plate 6 has threaded holes on its inner side, and the cooling fan 7 is mounted on the outer side of the mounting plate 6 by fixing screws.

[0027] In this embodiment, a dustproof assembly is provided on the heat sink 2. The dustproof assembly includes an air inlet mesh 3 fixedly connected to the side of the heat sink 2 and an exhaust mesh 4 fixedly connected to the top of the heat sink 2. The air inlet end of the cooling fan 7 corresponds to the exhaust mesh 4. A first dustproof plate 8 is provided on the outer side of the air inlet mesh 3. The end of the first dustproof plate 8 away from the hydraulic gear pump 1 is movably hinged to the heat sink 2. A limit component is provided between the first dustproof plate 8 and the hydraulic gear pump 1. A second dustproof plate 15 is provided on the upper side of the exhaust mesh 4. The second dustproof plate 15 is slidably installed between two fixed plates 5. The first dustproof plate 8 can shield and protect the air inlet mesh 3, and the second dustproof plate 15 can shield and protect the exhaust mesh 4.

[0028] It should be noted that both the air inlet screen 3 and the air outlet screen 4 are equipped with dustproof screens, which can not only play a certain role in dust prevention, but also facilitate air circulation.

[0029] The number of limiting components is set to two sets, and the two sets of limiting components are located on the upper and lower sides of the first dustproof plate 8, respectively.

[0030] It should be noted that the limiting assembly includes a connecting piece 9 fixedly connected to the outer wall of the first dustproof plate 8 and a fixed box 10 fixedly connected to the outside of the hydraulic gear pump 1. The fixed box 10 is provided with a limiting rod 11 running through it vertically. One end of the limiting rod 11 extends to the inner side of the connecting piece 9. A pull head 12 is fixedly connected to the end of the limiting rod 11 away from the connecting piece 9. A through hole adapted to the limiting rod 11 is opened on the inner side of the connecting piece 9. A spring 13 and a support piece 14 are respectively provided inside the fixed box 10. The spring 13 is sleeved on the outer wall of the limiting rod 11. The support piece 14 is fixedly connected to the outer wall of the limiting rod 11. The support piece 14 is located at the end of the spring 13 corresponding to the connecting piece 9. The end of the spring 13 away from the support piece 14 abuts against the inner wall of the fixed box 10. The position of the limiting rod 11 can be elastically adjusted by the cooperation of the pull head 12, the spring 13, and the support piece 14. The first dustproof plate 8 can be limited by the cooperation of the limiting rod 11 and the connecting piece 9.

[0031] It should be noted that a sliding groove is provided on the inner side of the mounting plate 6, and a slider is provided on the second dustproof plate 15 near the sliding groove to slide with it. The side of the sliding groove away from the fixed plate 5 is not through-hole, so that the slider will not separate from the mounting plate 6, thereby preventing the second dustproof plate 15 from separating from the mounting plate 6. A positioning plate 16 is fixedly connected to the end of the second dustproof plate 15 away from the fixed plate 5. A magnetic block 17 is provided at the end of the mounting plate 6, and a magnetic piece is provided on the positioning plate 16 at the position corresponding to the magnetic block 17. When the second dustproof plate 15 blocks and protects the exhaust net 4, the magnetic attraction between the magnetic block 17 and the magnetic piece on the positioning plate 16 achieves the positioning function of the second dustproof plate 15.

[0032] The working principle of the above embodiments is as follows:

[0033] When the hydraulic gear pump 1 is running, the position of the limiting rod 11 is elastically adjusted by the cooperation of the pull head 12, the spring 13 and the support plate 14, so that the limiting rod 11 and the connecting plate 9 are separated, thereby opening the first dustproof plate 8. External air can flow into the heat dissipation shroud 2 through the air inlet net 3. At the same time, the second dustproof plate 15 is slid open, so that the exhaust net 4 corresponds to the cooling fan 7. With the cooperation of the heat dissipation shroud 2, the air inlet net 3, the exhaust net 4 and the cooling fan 7, the air flow around the hydraulic gear pump 1 is improved, which facilitates the rapid removal of heat from the inside of the hydraulic gear pump 1 and improves the heat dissipation effect.

[0034] During the heat dissipation process, the dustproof nets on the air inlet net 3 and the exhaust net 4 can also play a certain role in dust prevention. When the hydraulic gear pump 1 is not in use, the first dustproof plate 8 and the second dustproof plate 15 are reset. The first dustproof plate 8 can block and protect the air inlet net 3, and the second dustproof plate 15 can block and protect the exhaust net 4, thereby achieving a tight seal inside the heat dissipation cover 2 and playing a stable dust prevention role.

[0035] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented. It should be noted that the orientation or positional relationship indicated herein is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
