Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic power units, and in particular relates to a power unit regulating plate structure. Background Art

[0002] The hydraulic power unit (HPU) serves as an oil supply device, connected to several hydraulic cylinders via an external piping system to control multiple valves. The oil tank, pump, and accumulator form an independent, sealed power oil supply system. The oil station can be equipped with a PLC control system, which controls all internal hydraulic functions and generates signals for communication with the control center (DCS). The HPU is the power source in the hydraulic system and is connected to the hydraulic cylinders via multiple piping systems.

[0003] In the process of realizing the present utility model, the inventors discovered that there are at least the following problems in this technology: in order to ensure the heat dissipation effect of the existing hydraulic power unit, it is either directly exposed to the outside world or an active heat dissipation mechanism is set in a closed space. However, no matter which method is used, the problem of large amounts of dust falling cannot be avoided. If a heat dissipation mechanism is not set, the heat dissipation effect cannot be guaranteed, and therefore it is impossible to strike a balance between the two dimensions of heat dissipation and dust prevention.

[0004] To this end, we propose a power unit adjustment plate structure to solve the above problems. Utility Model Content

[0005] The main purpose of the present invention is to provide a power unit adjustment plate structure, which can effectively dissipate heat for the power unit and greatly reduce dust ingress, thereby achieving a relative balance in the two dimensions of heat dissipation and dust prevention, and can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A power unit adjustment plate structure includes a fixed plate, a storage seat integrally welded to one side of the fixed plate, and a power unit located in the inner cavity of the storage seat, wherein the power unit is fixedly mounted on the bottom wall of the inner cavity of the storage seat, and its installation method is the existing technology;

[0008] A cylinder is fixedly installed on the top wall of the storage seat, wherein a telescopic rod is connected to the bottom of the cylinder, a movable plate is welded to the bottom of the telescopic rod, and a temperature sensor is installed under the movable plate. When the temperature sensor is extended downward to the lowest point, it can be close to the upper surface of the power unit, so as to facilitate the monitoring of the temperature on the upper surface of the power unit. Of course, the positional relationship between the temperature sensor and the power unit can be determined according to actual needs. For example, the temperature sensor can be set near the position where the heat is most generated on the power unit. A controller is also installed on the top wall of the inner cavity of the storage seat, and an air inlet hole communicating with the inner cavity of the storage seat is formed on the fixed plate. A fan is installed in the air inlet hole, and the fan needs to be driven by external power facilities.

[0009] A servo motor is horizontally installed at the bottom of the side of the storage seat facing away from the fixed plate, and a bottom groove is formed on the bottom wall of the inner cavity of the storage seat close to the servo motor, wherein the output shaft of the servo motor is coaxially connected to a screw rod, and a bottom slider is threadedly installed on the screw rod, and the bottom slider is fitted with the bottom wall of the bottom groove, so that when the screw rod is running, the bottom slider can be driven to translate along the bottom wall of the bottom groove. The servo motor requires power supply from external power facilities, and an L-shaped side sealing plate is welded on the bottom slider.

[0010] As a preferred embodiment, threaded holes are tapped in the horizontal direction at the four corners of the fixing plate; this facilitates the installation of bolts at the four corners of the fixing plate. When the side of the fixing plate facing away from the storage seat is attached to a wall or other attachable structure, the fixing plate, the storage seat and the power unit can be fixed to the attached structure by four bolts, so that the power unit remains stable.

[0011] As a preferred embodiment, a mounting shell in a U-shaped design is fixedly bonded to the top wall of the storage seat, wherein the mounting shell is sleeved on the outside of the cylinder; thereby facilitating the use of the mounting shell to provide a certain degree of protection to the cylinder.

[0012] As a preferred embodiment, the screw is horizontally arranged inside the bottom groove, and the screw is rotatably connected to the storage seat; so that the servo motor can drive the screw to operate more stably when it is running.

[0013] As a preferred embodiment, the four side walls of the side sealing plate are all in contact with the inner wall of the storage seat, so that when the side sealing plate is retracted into the inner cavity of the storage seat, the opening of the inner cavity of the storage seat can be sealed.

[0014] As a preferred embodiment, the wind direction of the fan is from the external environment to the inner cavity of the storage seat; thereby ensuring that the external cold air is blown into the storage seat under the action of the fan, thereby dissipating heat for the power unit.

[0015] As a preferred embodiment, a dustproof net is fixedly installed at the opening of the air inlet hole on the side where the fixing plate is located; thereby reducing the dust entering the inner cavity of the storage seat.

[0016] In summary, the technical effects and advantages of the utility model are:

[0017] The power unit adjustment plate structure has a temperature sensor inside the storage seat that is close to the outer surface of the power unit in real time to monitor the temperature near the outer surface of the power unit. When the monitored temperature reaches the set high temperature threshold, it transmits an electrical signal to the controller, causing the controller to drive the servo motor to operate, drive the side sealing plate to move outward, and then open the storage seat and drive the fan to blow directly towards the power unit, thereby facilitating rapid heat dissipation. When the temperature drops to the low temperature threshold, the side sealing plate returns to its original position and the fan stops, which greatly reduces dust ingress, thereby achieving a relative balance between heat dissipation and dust prevention.

[0018] The power unit adjusts the plate structure. When the temperature of the inner cavity of the storage seat is too high, the fan will blow cold air from the outside into the inner cavity of the storage seat. The operation of the servo motor will drive the screw to rotate in the forward direction, driving the bottom slider and the side sealing plate to move horizontally in the direction away from the fixed plate. When the side sealing plate extends from the inner cavity of the storage seat, the air blown by the fan can be discharged from the opening of the storage seat, discharging the heat from the inner cavity of the storage seat, thereby avoiding overheating.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Reference Figure 1-Figure 5 A power unit adjustment plate structure includes a fixing plate 1, a storage seat 2 integrally welded to one side of the fixing plate 1, and a power unit 3 located in the inner cavity of the storage seat 2, wherein the power unit 3 is fixedly mounted on the bottom wall of the inner cavity of the storage seat 2, and its mounting method is the existing technology, with threaded holes tapped in the horizontal direction at the four corners of the fixing plate 1, so as to facilitate the installation of bolts at the four corners of the fixing plate 1. When the side of the fixing plate 1 facing away from the storage seat 2 is attached to a wall or other attachable structure, the fixing plate 1, the storage seat 2 and the power unit 3 can be fixed to the attached structure by four bolts, so that the power unit 3 remains stable and immovable;

[0027] A cylinder 4 is fixedly mounted on the top wall of the storage seat 2, and a mounting shell 5 with a mouth-shaped design is fixedly bonded to the top wall of the storage seat 2, wherein the mounting shell 5 is sleeved on the outside of the cylinder 4, so that the mounting shell 5 is used to protect the cylinder 4 to a certain extent, wherein a telescopic rod 6 is connected to the bottom of the telescopic rod 6, and a movable plate 7 is welded to the bottom of the telescopic rod 6, and a temperature sensor 8 is installed under the movable plate 7. When the temperature sensor 8 is extended downward to the lowest point, it can be close to the upper surface of the power unit 3, so as to facilitate monitoring the temperature at the upper surface of the power unit 3. Of course, the positional relationship between the temperature sensor 8 and the power unit 3 can be determined according to actual needs. For example, the temperature sensor 8 can be set near the position on the power unit 3 where the heat is most generated. A controller 9 is also installed on the top wall of the inner cavity of the storage seat 2, wherein the temperature sensor 8 can refer to the technical principle of the pt100 model, and the controller 9 can refer to the technical principle of the S7-200 model;

[0028] In addition, an air inlet 15 is formed on the fixed plate 1, which is in communication with the inner cavity of the storage seat 2. A fan 16 is installed in the air inlet 15. The fan 16 requires external power facilities to drive. The wind direction of the fan 16 is the wind direction from the external environment to the inner cavity of the storage seat 2, thereby ensuring that the external cold air is blown into the storage seat 2 under the action of the fan 16, thereby dissipating heat for the power unit 3. A dustproof net 17 is fixedly installed at the opening of the air inlet 15 on the side where the fixed plate 1 is located, thereby reducing the dust from entering the inner cavity of the storage seat 2.

[0029] A servo motor 10 is horizontally installed at the bottom of the side of the storage seat 2 facing away from the fixed plate 1, and a bottom groove 11 is formed on the bottom wall of the inner cavity of the storage seat 2 near the servo motor 10, wherein the output shaft of the servo motor 10 is coaxially connected with a screw 12, and the screw 12 is horizontally arranged on the inner side of the bottom groove 11, and the screw 12 is rotatably connected to the storage seat 2, so that the servo motor 10 can drive the screw 12 to operate more stably when it is running. A bottom slider 13 is threadedly mounted on the screw 12, and the bottom slider 13 is in contact with the bottom wall of the bottom groove 11, so that when the screw 12 is running, it can drive the bottom slider 13 to move horizontally along the bottom wall of the bottom groove 11. The servo motor 10 requires power supply from external power facilities. An L-shaped side sealing plate 14 is welded on the bottom slider 13, and the four side walls of the side sealing plate 14 are in contact with the inner wall of the storage seat 2, so that when the side sealing plate 14 is retracted into the inner cavity of the storage seat 2, the opening of the inner cavity of the storage seat 2 can be closed.

[0030] The power unit adjustment plate structure: when in use, while the power unit 3 is running, the cylinder 4 is driven to run according to actual conditions, so that it drives the telescopic rod 6, the movable plate 7 and the temperature sensor 8 to move, and finally the temperature sensor 8 is close to the outer surface of the power unit 3, so that the temperature sensor 8 monitors the temperature at the outer surface of the power unit 3 in real time. When the temperature reaches a preset high temperature threshold (for example, 50°C), the temperature sensor 8 transmits an electrical signal to the controller 9, so that the controller 9 drives the fan 16 and the servo motor 10 to run simultaneously, wherein the fan 16 blows external cold air into the inner cavity of the storage seat 2 when it is running, and the operation of the servo motor 10 drives the screw 12 to run forward, driving the bottom slider 13 and the side sealing plate 14 to move horizontally in the direction away from the fixed plate 1, and when the side sealing plate 14 extends from the inner cavity of the storage seat 2, the air blown out by the fan 16 can be discharged from the opening of the storage seat 2, thereby automatically discharging the heat from the inner cavity of the storage seat 2 to avoid overheating;

[0031] When the temperature gradually drops to a preset low temperature threshold (for example, 30°C), the controller 9 transmits an electrical signal to the servo motor 10 and the fan 16. At this time, the fan 16 stops rotating, and the servo motor 10 drives the screw 12 to rotate in the reverse direction, so that the side sealing plate 14 returns to its original position (closing the opening of the inner cavity of the storage seat 2), so that almost no dust will enter the inner cavity of the storage seat 2.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
