Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to a hydraulic pump for electromechanical equipment. Background Technology

[0002] Hydraulic pumps for electromechanical equipment are power components in electromechanical systems. They convert the mechanical energy of power sources such as electric motors into hydraulic energy. By drawing in and compressing hydraulic oil and outputting high-pressure oil, they provide power to actuators such as hydraulic cylinders and hydraulic motors in the equipment, driving the equipment to complete actions such as extension, rotation, etc. They also have pressure regulation and flow control functions to ensure the stable operation of electromechanical equipment.

[0003] However, hydraulic pumps generate a lot of heat during operation. Most hydraulic pumps dissipate heat through natural dissipation. However, this method is inefficient and cannot meet the heat dissipation requirements under long-term high-load operation. Air cooling and other methods often fail to adequately guide the airflow, resulting in a large amount of airflow escaping and failing to fully exchange heat with the heat exchange fins, thus affecting the heat dissipation efficiency.

[0004] Therefore, we provide a hydraulic pump for electromechanical equipment to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a hydraulic pump for electromechanical equipment, aiming to solve the aforementioned problems.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: It includes a support base, with a lower shock-absorbing rubber pad on the upper side of the support base. A hydraulic pump body is mounted on the upper side of the lower shock-absorbing rubber pad. An upper heat-conducting rubber pad is provided on the upper surface of the hydraulic pump body. A hydraulic pump heat dissipation assembly is provided on the outer side of the hydraulic pump body. Heat dissipation fins are provided on the upper side of the upper heat-conducting rubber pad. A right-side air duct cover is connected to the right end of the outer side of the hydraulic pump body via a slot. An outer cover fixing plate is welded to the lower side of the right-side air duct cover. An end ventilation hole is provided on the right outer edge of the right-side air duct cover. A left-side air duct cover is connected to the left end of the hydraulic pump body via a slot. An air inlet mesh is welded to the inside of the left side of the left-side air duct cover. A motor controller is provided on the upper side of the air inlet mesh.

[0007] Preferably, the hydraulic pump body and the support base are connected by a slot and fixed by screws, and the hydraulic pump body and the support base are damped by a lower shock-absorbing pad.

[0008] Preferably, the upper thermally conductive pad is tightly attached to the upper surface of the hydraulic pump body, and the heat dissipation fins conduct heat to the hydraulic pump body through the upper thermally conductive pad.

[0009] Preferably, the right-side air duct cover and the left-side air duct cover enclose the hydraulic pump body. The right-side air duct cover and the left-side air duct cover are connected by bolts. The right-side air duct cover and the left-side air duct cover are fixed to the outside of the support base by cover fixing bolts. The right-side air duct cover and the left-side air duct cover, together with the end ventilation holes, form a ventilation duct.

[0010] Preferably, the air inlet mesh cover and the left air duct outer cover are welded together. A rotary motor is welded to the middle of the air inlet mesh cover, and a cooling fan is connected to the end shaft of the rotary motor. The cooling fan provides air cooling to the right air duct outer cover and the left air duct outer cover through the air inlet mesh cover.

[0011] Preferably, a plate buckle is welded to the outer side of the left air duct cover, and an upper cover plate is installed on the upper side of the right air duct cover and the left air duct cover, and a cover plate heat dissipation mesh is provided in the middle of the upper cover plate.

[0012] Preferably, the ends of the heat dissipation fins are tightly fitted to the inner wall of the upper cover plate, and the heat dissipation fins, together with the gap in the middle of the upper cover plate, form a heat dissipation air duct. The gap between the heat dissipation fins and the upper cover plate corresponds one-to-one with the heat dissipation mesh of the cover plate.

[0013] This utility model provides a hydraulic pump for electromechanical equipment. Compared with the prior art, it has the following advantages:

[0014] 1. In this hydraulic pump for electromechanical equipment, when in use, the right-side air duct cover and the left-side air duct cover are fixed to the outside of the hydraulic pump body by the cover fixing bolts. Then, the upper cover plate is used to close and fix the left-side air duct cover and the right-side air duct cover by the plate buckle, so that the heat dissipation air duct formed by the right-side air duct cover and the left-side air duct cover is effectively sealed, reducing the large-scale loss of airflow and improving the air cooling efficiency. Thus, an air duct structure is formed. The airflow enters from the air inlet mesh cover of the left-side air duct cover, is guided to the vicinity of the hydraulic pump body through the air duct, carries away the heat on the heat dissipation fins, and is discharged through the end ventilation hole, thereby achieving the purpose of effective heat dissipation.

[0015] 2. This hydraulic pump for electromechanical equipment uses a rotating motor to drive a cooling fan that draws in external air through the air inlet grille. The forced airflow passes through the closed air duct formed by the right and left air duct covers, evenly blowing on the surface of the heat dissipation fins, significantly improving heat exchange efficiency and ensuring that the hydraulic pump maintains a stable operating temperature during continuous operation. When the heat dissipation fins are cooled by air, the air duct in the middle of the heat dissipation fins is closed, and it is difficult to quickly expel hot air by relying solely on the airflow from the end ventilation holes, which can easily cause an increase in internal air pressure. At this time, after the airflow passes through the heat dissipation fins, some of the heat will be quickly discharged through the heat dissipation mesh of the upper cover plate corresponding to the gaps in the heat dissipation fins, improving the heat exchange efficiency of the heat dissipation fins and effectively alleviating the heat dissipation bottleneck caused by airflow obstruction.

[0022] 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.

[0023] Please see Figure 1-5This utility model provides a technical solution: a hydraulic pump for electromechanical equipment, including a support base 1, a lower shock-absorbing rubber pad 2 on the upper side of the support base 1, a hydraulic pump body 3 mounted on the upper side of the lower shock-absorbing rubber pad 2, an upper heat-conducting rubber pad 4 on the upper surface of the hydraulic pump body 3, a hydraulic pump heat dissipation assembly 5 on the outer side of the hydraulic pump body 3, heat dissipation fins 501 on the upper side of the upper heat-conducting rubber pad 4, a right-side air duct cover 502 connected to the outer right end of the hydraulic pump body 3 by a slot, an outer cover fixing plate 503 welded to the lower side of the right-side air duct cover 502, an end ventilation hole 504 on the right outer edge of the right-side air duct cover 502, a left-side air duct cover 505 connected to the outer left end of the hydraulic pump body 3 by a slot, an air inlet mesh cover 506 welded to the left inner side of the left-side air duct cover 505, and a motor controller 509 on the upper side of the air inlet mesh cover 506.

[0024] The hydraulic pump body 3 and the support base 1 are connected by a slot and fixed by screws. The hydraulic pump body 3 and the support base 1 are damped by a lower shock-absorbing pad 2.

[0025] When needed, the vibration generated after the hydraulic pump body 3 is fixed to the upper side of the support base 1 is effectively buffered by the lower shock-absorbing rubber pad 2, reducing the transmission of vibration during equipment operation and thus achieving noise reduction.

[0026] The upper thermally conductive pad 4 is tightly attached to the upper surface of the hydraulic pump body 3, and the heat dissipation fins 501 conduct heat to the hydraulic pump body 3 through the upper thermally conductive pad 4.

[0027] When needed, the heat generated by the hydraulic pump body 3 is quickly conducted to the heat dissipation fins 501 through the upper thermal conductive pad 4. The heat dissipation area is increased by the heat dissipation fins 501. In addition to conducting heat, the upper thermal conductive pad 4 can also provide a certain shock absorption effect, reducing the hard friction between the heat dissipation fins 501 and the hydraulic pump body 3.

[0028] The right-side air duct cover 502 and the left-side air duct cover 505 enclose the hydraulic pump body 3. The right-side air duct cover 502 and the left-side air duct cover 505 are connected by bolts. The right-side air duct cover 502 and the left-side air duct cover 505 are fixed to the outside of the support base 1 by the cover fixing bolt plate 503. The right-side air duct cover 502 and the left-side air duct cover 505 together with the end ventilation hole 504 form a ventilation air duct.

[0029] When needed, the right-side air duct cover 502 and the left-side air duct cover 505 are fixed to the outside of the hydraulic pump body 3 by the cover fixing bolt plate 503, thus forming an air duct structure. The airflow enters from the air inlet mesh cover 506 of the left-side air duct cover 505, is guided to the vicinity of the hydraulic pump body 3 through the air duct, carries away the heat on the heat dissipation fins 501, and is then discharged through the end ventilation hole 504, thereby achieving the purpose of effective heat dissipation.

[0030] The air inlet mesh cover 506 and the left air duct outer cover 505 are welded together. A rotary motor 507 is welded in the middle of the air inlet mesh cover 506. A cooling fan 508 is connected to the end shaft of the rotary motor 507. The cooling fan 508 provides air cooling to the right air duct outer cover 502 and the left air duct outer cover 505 through the air inlet mesh cover 506.

[0031] When needed, the rotary motor 507 drives the cooling fan 508 to draw in external air from the air inlet mesh cover 506. The forced airflow passes through the closed air duct formed by the right air duct cover 502 and the left air duct cover 505, and blows evenly on the surface of the heat dissipation fins 501, greatly improving the heat exchange efficiency and ensuring that the hydraulic pump body 3 maintains a stable working temperature during continuous operation.

[0032] A plate buckle 510 is welded to the outside of the left air duct cover 505. An upper cover plate 511 is installed on the upper side of the right air duct cover 502 and the left air duct cover 505. A cover plate heat dissipation mesh 512 is provided in the middle of the upper cover plate 511.

[0033] When needed, the upper cover 511 is used to seal and fix the left air duct cover 505 and the right air duct cover 502 with the plate buckle 510, so that the heat dissipation air duct formed by the right air duct cover 502 and the left air duct cover 505 is effectively sealed, reducing the large-scale dissipation of airflow and improving the air cooling efficiency.

[0034] The ends of the heat dissipation fins 501 are tightly fitted to the inner wall of the upper cover plate 511. The heat dissipation fins 501 and the gap in the middle of the upper cover plate 511 form a heat dissipation air channel. The gap between the heat dissipation fins 501 and the upper cover plate 511 corresponds one-to-one with the heat dissipation mesh 512 of the cover plate.

[0035] When the heat sink 501 is used for air cooling, the air duct in the middle of the heat sink 501 is closed. It is difficult to quickly expel hot air by relying solely on the air volume of the end ventilation hole 504, which can easily cause the internal air pressure to rise. At this time, after the airflow passes through the heat sink 501, some of the heat will be quickly discharged through the heat dissipation mesh 512 of the cover plate 511, which corresponds to the gap of the heat sink 501, thereby improving the heat exchange efficiency of the heat sink 501 and effectively alleviating the heat dissipation bottleneck caused by airflow obstruction.

[0036] Working principle: When needed, place the support base 1 in the required position, then place the lower shock-absorbing pad 2 between the hydraulic pump body 3 and the support base 1 and fix it with bolts. Then, attach the upper heat-conducting pad 4 to the upper surface of the hydraulic pump body 3 and clip the heat dissipation fins 501 to the outside of the upper heat-conducting pad 4, and tightly fit them against the heat dissipation surface of the hydraulic pump body 3. After fixing, wrap the right air duct cover 502 and the left air duct cover 505 around the outside of the hydraulic pump body 3 from the right and left sides respectively, and fix them to the outside of the support base 1 with the cover fixing bolts 503. Then fix the right air duct cover 502 and the left air duct cover 505 with bolts. After installation, fix the upper cover plate 511 to the upper side of the right air duct cover 502 and the left air duct cover 505 with the plate buckle 510 to form a complete air duct.

[0037] Once ready, the hydraulic pump body 3 is started, and the motor controller 509 is started, controlling the rotary motor 507 to drive the cooling fan 508 for air cooling. At this time, the cold air enters the upper cover plate 511 through the air inlet mesh 506. The airflow will contact the heat dissipation fins 501, and the heat will be discharged from the end ventilation hole 504 with the airflow. Some of the hot air in the middle of the heat dissipation fins 501 will be assisted in exhausting through the cover plate heat dissipation mesh 512 on the surface of the upper cover plate 511, thereby improving the heat dissipation efficiency. This completes the use of a hydraulic pump for electromechanical equipment.

[0038] Although embodiments of the present invention have been shown and described, 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.
