Description

Technical Field

[0001] This utility model relates to the field of throttling technology, and in particular to a throttling device for a heat pump system. Background Technology

[0002] A heat pump system is a device that uses the reverse Carnot cycle principle to convert low-temperature heat energy into high-temperature heat energy by consuming a small amount of high-grade energy.

[0003] Throttling devices are one of the key components in heat pump systems. Their function is to throttle and reduce the pressure of fluids and regulate the flow rate to ensure the normal operation of the heat pump system. In existing technologies, traditional throttling valves are usually used, but their throttling accuracy is low and they cannot be precisely adjusted according to the actual operating conditions of the heat pump system. When the load of the heat pump system changes, traditional throttling valves cannot adjust the flow rate of the fluid in time, resulting in reduced system energy efficiency and insufficient practicality. Therefore, it is necessary to redesign a throttling device for heat pump systems to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a throttling device for heat pump systems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A throttling device for a heat pump system includes a heat pump system body. A rotating rod is rotatably mounted inside the heat pump system body. A throttling plate is fixedly mounted on the outer wall of the rotating rod. A gear is fixedly mounted on the outer wall of the rotating rod. A fixing plate is fixedly mounted on the outer wall of the heat pump system body. A connecting block is fixedly mounted on the inner wall of the fixing plate via a telescopic mechanism. A toothed plate is fixedly mounted on the outer wall of the connecting block via a connecting mechanism. The toothed plate meshes with the gear. A filter box is fixedly mounted on the outer wall of the heat pump system body. A cleaning opening is provided on the outer wall of the filter box. A filter screen is fixedly mounted inside the filter box. A reciprocating screw is rotatably mounted on the outer wall of the filter box via a moving frame. A motor connected to the reciprocating screw is fixedly mounted on the outer wall of the moving frame. A moving plate is threaded onto the outer wall of the reciprocating screw. A cleaning brush is fixedly mounted on the inner wall of the moving plate via a connecting mechanism. A support plate is fixedly mounted on the outer wall of the filter box. A connecting block is fixedly mounted on the bottom wall of the support plate via a lifting mechanism. A sealing plate is fixedly mounted at the end of the connecting block.

[0007] Preferably, the telescopic mechanism includes a cylinder fixedly installed on the inner wall of the fixed plate, and the telescopic end of the cylinder is fixedly connected to the outer wall of the connecting block.

[0008] Preferably, the connecting mechanism includes a connecting rod fixedly installed on the outer wall of the connecting block, and the end of the connecting rod is fixedly connected to the outer wall of the toothed plate.

[0009] Preferably, the connecting mechanism includes two connecting rods fixedly installed on the inner wall of the movable plate, the ends of the two connecting rods being fixedly connected to the outer wall of the cleaning brush, and the two connecting rods slidingly penetrating the filter box.

[0010] Preferably, the lifting mechanism includes an electric actuator fixedly installed on the bottom wall of the support plate, and the telescopic end of the electric actuator is fixedly connected to the outer wall of the connecting block.

[0011] Preferably, a sealing gasket that mates with the cleaning opening is fixedly installed on the inner wall of the sealing plate, and the sealing gasket is made of vulcanized rubber.

[0012] The beneficial effects of this utility model are:

[0013] 1. By setting up components such as rotating rods, gears, and toothed plates, the moving connecting block can drive the toothed plate to move. When the toothed plate and gear mesh with each other, they can drive the rotating rod to rotate. When the rotating rod rotates, it can drive the throttling plate to flip.

[0014] 2. By setting up components such as electric push rods, sealing plates and sealing gaskets, the extension and retraction of the electric push rods can push the connecting block and sealing plate to seal the cleaning opening. The cooperation between the sealing plate and the sealing gasket can ensure the airtightness of the filter box and prevent fluid from leaking out of the cleaning opening. Attached Figure Description

Detailed Implementation

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A throttling device for a heat pump system includes a heat pump system body 1. A rotating rod 2 is rotatably mounted inside the heat pump system body 1. A throttling plate 3 is fixedly mounted on the outer wall of the rotating rod 2. A gear 4 is fixedly mounted on the outer wall of the rotating rod 2. A fixing plate 5 is fixedly mounted on the outer wall of the heat pump system body 1. A connecting block 7 is fixedly mounted on the inner wall of the fixing plate 5 via a telescopic mechanism. The telescopic mechanism includes a cylinder 6 fixedly mounted on the inner wall of the fixing plate 5. The telescopic end of the cylinder 6 is fixedly connected to the outer wall of the connecting block 7. A toothed plate 9 is fixedly mounted on the outer wall of the connecting block 7 via a connecting mechanism. The connecting mechanism includes a connecting rod 8 fixedly mounted on the outer wall of the connecting block 7. The end of the connecting rod 8 is fixedly connected to the outer wall of the toothed plate 9. The toothed plate 9 and the gear... 4. The heat pump system body 1 has a filter box 10 fixedly installed on its outer wall. The filter box 10 has a cleaning opening on its outer wall. The filter screen plate 11 is fixedly installed inside the filter box 10. The filter box 10 has a reciprocating screw 13 rotatably installed on its outer wall via a moving frame 12. The moving frame 12 has a motor 14 fixedly installed on its outer wall and connected to the reciprocating screw 13. The reciprocating screw 13 has a moving plate 15 threaded on its outer wall. The moving plate 15 has a cleaning brush 17 fixedly installed on its inner wall via a connecting mechanism. The connecting mechanism includes two connecting rods 16 fixedly installed on the inner wall of the moving plate 15. The ends of the two connecting rods 16 are fixedly connected to the outer wall of the cleaning brush 17. The two connecting rods 16 slide through the filter box 10.

[0023] A support plate 18 is fixedly installed on the outer wall of the filter box 10. A connecting block 20 is fixedly installed on the bottom wall of the support plate 18 via a lifting mechanism. The lifting mechanism includes an electric push rod 19 fixedly installed on the bottom wall of the support plate 18. The telescopic end of the electric push rod 19 is fixedly connected to the outer wall of the connecting block 20. A sealing plate 21 is fixedly installed on the end of the connecting block 20. A sealing gasket 22 that matches the cleaning opening is fixedly installed on the inner wall of the sealing plate 21. The sealing gasket 22 is made of vulcanized rubber. Vulcanized rubber refers to rubber that has been vulcanized. It has properties such as not being sticky and not being easy to break. Most rubber products are made of this type of rubber. It has high elasticity, heat resistance, tensile strength, and insolubility in organic solvents.

[0024] When this utility model is in use, if it is necessary to adjust the throttling of the heat pump system, the connecting block 7 can be moved by the extension and retraction of the cylinder 6. When the connecting block 7 moves, it can drive the toothed plate 9 to move synchronously through the cooperation with the connecting rod 8. Since the toothed plate 9 and the gear 4 fixedly installed on the outer wall of the rotating rod 2 mesh with each other, the movement of the toothed plate 9 will cause the gear 4 to rotate, thereby driving the rotating rod 2 to rotate inside the heat pump system body 1. The rotation of the rotating rod 2 can adjust the throttling state inside the heat pump system body 1, thereby realizing flexible control of the throttling degree of the heat pump system body 1, so as to adjust the flow rate of the fluid in a timely manner. The fluid inside the heat pump system body 1 enters the filter box 10 fixedly installed on the outer wall of the heat pump system body 1. The filter screen plate 11 inside the filter box 10 will intercept and filter impurities and particles in the fluid, ensuring that the fluid entering the subsequent links of the heat pump system is relatively clean, reducing the wear and blockage of system components by impurities, and ensuring the normal operation of the system.

[0025] When a certain amount of impurities accumulate on the surface of the filter screen plate 11, the motor 14 can drive the reciprocating screw 13 to rotate. When the reciprocating screw 13 rotates, it can drive the moving plate 15 to move back and forth on its outer wall. When the moving plate 15 moves, it can drive the cleaning brush 17 to move synchronously through the cooperation of the two connecting rods 16. During the movement, the cleaning brush 17 sweeps the surface of the filter screen plate 11 and brushes off the impurities on the surface of the filter screen plate 11. The brushed-off impurities fall to the bottom of the filter box 10. Then, the sealing plate 21 and the sealing gasket 22 can ensure the sealing of the filter box 10 and prevent fluid from leaking from the cleaning opening. When it is necessary to clean the impurities discharged from the cleaning opening, the connecting block 20 and the sealing plate 21 can be pushed upward by the extension and retraction of the electric push rod 19 to open the cleaning opening and facilitate the staff to clean the impurities. After cleaning, the electric push rod 19 retracts, so that the sealing plate 21 seals the cleaning opening again.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
