In addition, unless otherwise clearly defined and limited, the terms "installation", "connection", "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0022] Embodiment: Please refer to Figures 1 - 8 , an energy-saving screw compressor for a cold storage, including a main body 1, and an extrusion assembly 2 is fixedly installed at the end of the main body 1. The gas is quickly introduced into the main body 1 through the extrusion assembly 2.

[0023] In this solution, the external gas is extruded into the main body 1 through the extrusion assembly 2. By controlling the air flow velocity, it helps to more evenly distribute air or gas, avoid local overheating or overcooling phenomena, and accelerating the air flow velocity can more effectively conduct heat exchange and reduce the overheating problem.

[0024] Further, the pressing assembly 2 includes a fixing plate 21 fixedly connected to the main body 1. A positioning shaft 22 is fixedly installed at the end of the fixing plate 21, and an adjusting rod 221 is rotatably installed on the outer surface of the positioning shaft 22.

[0025] In this embodiment, a motor is fixedly installed at the end of the adjusting rod 221, and the end of the motor is rotatably connected to the outer surface of the positioning shaft 22. When the motor is started, it drives the adjusting rod 221 to rotate. Threads are provided on the outer surface of the adjusting rod 221. Thus, when the adjusting rod 221 rotates, it synchronously drives an adjusting block 24 slidably installed on its outer surface to move until it stops at the optimal position.

[0026] Further, an adjusting block 24 is rotatably installed at the end of the fixing plate 21 and on one side of the positioning shaft 22. The inner wall of the end of the adjusting block 24 is threadedly connected to the outer surface of the adjusting rod 221.

[0027] Specifically, when the adjusting block 24 moves, it rotates around the connection between the adjusting block 24 and the fixing plate 21, so as to ensure that the adjusting block 24 is in a stable state during movement.

[0028] Further, a driving member 23 is fixedly installed at the end of the fixing plate 21 and on one side of the positioning shaft 22. A driving plate 231 is fixedly installed at the output end of the driving member 23. A swing plate 25 is rotatably installed at the end of the driving plate 231. A limiting plate 251 is installed at the end of the swing plate 25, and the end of the limiting plate 251 is rotatably connected to the end of the adjusting block 24.

[0029] Specifically, the driving member 23 is a device with power output such as a motor and is connected to an external control device. When the driving member 23 is started, it synchronously drives the driving plate 231 fixedly installed at its output end to rotate. Since the swing plate 25 is rotatably installed at the end of the driving plate 231, the swing plate 25 is synchronously driven to move.

[0030] The end of the limiting plate 251 is rotatably connected to the end of the adjusting block 24. Thus, when the swing plate 25 moves, it is limited by the adjusting block 24, so as to control the moving range of the swing plate 25 and make it applicable to different scenarios.

[0031] Further, a driving rod 26 is rotatably installed at the end of the swing plate 25 and on one side of the limiting plate 251. A sealing plate 271 is rotatably installed at the end of the driving rod 26. A transmission cylinder 27 is communicated with the end of the fixing plate 21, and the inner wall of the transmission cylinder 27 is slidably connected to the outer surface of the sealing plate 271.

[0032] Specifically, when the swing plate 25 moves, it synchronously drives the driving rod 26 rotatably installed at its end to move. Since the sealing plate 271 is rotatably installed at the end of the driving rod 26, when the driving rod 26 moves, it drives the sealing plate 271 to move along the inner wall of the transmission cylinder 27, and the gas inside the transmission cylinder 27 is discharged from the main body 1 through the movement of the sealing plate 271. Sealing components such as rubber are provided on the outer surface of the sealing plate 271.

[0033] Further, an intake pipe 29 is connected to the outer surface of the transmission cylinder 27. A turning plate 291 is rotatably installed on the inner wall of the intake pipe 29, and a baffle 292 is fixedly installed on the inner wall of the intake pipe 29 and on one side of the turning plate 291.

[0034] Specifically, torsion springs are provided at both ends of the turning plate 291. Through the torsion springs, the turning plate 291 is tightly attached to the baffle 292, so that the intake pipe 29 is communicated with the outside, facilitating the entry of external gas. At the same time, when the sealing plate 271 moves, the air pressure inside the transmission cylinder 27 increases, thereby pushing the turning plate 291 to rotate until it tightly fits the inside of the intake pipe 29.

[0035] At the same time, when the sealing plate 271 moves in the reverse direction, the turning plate 291 is driven by the acting force of the torsion spring to return to its initial position.

[0036] Further, a support plate 28 is fixedly installed inside the transmission cylinder 27. An elastic member 281 is fixedly installed at the end of the support plate 28, and a circular plate 282 is fixedly installed at the end of the elastic member 281. At the same time, the outer surface of the circular plate 282 is in contact with the inner wall of the transmission cylinder 27.

[0037] Specifically, the elastic member 281 is an elastic component such as a spring. When the sealing plate 271 moves, it squeezes the internal gas, causing the circular plate 282 to separate from the transmission cylinder 27, so that the gas enters the main body 1. When the sealing plate 271 returns to its initial position, the circular plate 282 is returned to its initial position by the acting force of the elastic member 281. Sealing components such as rubber are provided on the outer surface of the circular plate 282.

[0038] Further, a guide groove 211 is formed at the end of the fixing plate 21, and the inner wall of the guide groove 211 is slidably connected to the outer surface of the end of the adjusting rod 221.

[0039] Specifically, when the adjusting rod 221 rotates, it drives the adjusting block 24 slidably installed on its outer surface to move, so that the adjusting rod 221 rotates around the positioning shaft 22. At the same time, the outer surface of the end of the adjusting rod 221 is slidably connected to the inner wall of the guide groove 211, thereby ensuring the overall stability of the adjusting rod 221 during movement.

[0040] Furthermore, the flow guiding assembly 3 is assembled on the inner wall of the extrusion assembly 2 to divert the gas entering the interior of the main body 1; the flow guiding assembly 3 includes a fixing block 31 fixedly connected to the inner wall of the transmission cylinder 27. Multiple groups of sliding grooves 32 are formed at the end of the inner cavity of the fixing block 31, and the multiple groups of sliding grooves 32 are evenly distributed in the inner cavity of the fixing block 31.

[0041] In this embodiment, multiple groups of support rods are arranged on the outer surface of the fixing block 31 to fix the fixing block 31 at the middle position of the transmission cylinder 27 through the support rods, ensuring the stability of the flow guiding assembly 3 during operation.

[0042] Furthermore, a slider 33 is slidably installed on the inner wall of the sliding groove 32. At the same time, a power rod 34 is rotatably installed at the end of the slider 33, and the end of the power rod 34 penetrates and extends to the outside of the fixing block 31.

[0043] Specifically, when the slider 33 is forced to move, it synchronously drives the power rod 34 rotatably installed at its end to move. The power rod 34 extends to the outside of the fixing block 31, thereby driving the flow guiding plate 39 fixedly installed at the end of the power rod 34 to move until it reaches the optimal position.

[0044] Furthermore, a power member 36 is fixedly installed at the middle position of the end of the inner cavity of the fixing block 31. The output end of the power member 36 is fixedly installed with a turntable 35, and the end of the turntable 35 is rotatably connected to the inner wall of the fixing block 31. A rotating rod 351 corresponding to the slider 33 is rotatably installed on the outer surface of the turntable 35, and the end of the rotating rod 351 away from the turntable 35 is rotatably connected to the end of the slider 33.

[0045] Specifically, the power member 36 is a device with power output such as a motor and is connected to an external control device. When the power member 36 is started, it synchronously drives the turntable 35 fixedly installed at its output end to rotate. At the same time, when the turntable 35 rotates, it drives the rotating rod 351 rotatably installed on the outer surface of the turntable 35 to move. Since the end of the rotating rod 351 is rotatably connected to the end of the slider 33, when the rotating rod 351 moves, it cooperates with the rotating rod 351 to drive the slider 33 to move along the inner wall of the sliding groove 32.

[0046] Furthermore, a positioning plate 37 corresponding to the power rod 34 is fixedly installed at the lower end of the fixing block 31, and a support block 38 is fixedly installed at the end of the positioning plate 37.

[0047] Specifically, a threaded groove is provided on the outer surface of the power rod 34, and a convex post is provided on the inner wall of the support block 38. The end of the convex post extends into the threaded groove. Thus, when the outer surface of the power rod 34 moves along the inner wall of the support block 38, the cooperation between the threaded groove and the convex post drives the power rod 34 to rotate. At the same time, the power rod 34 is limited by the slider 33 to ensure that the whole remains stable when the power rod 34 rotates.

[0048] Furthermore, the inner wall of the support block 38 is rotatably connected to the outer surface of the power rod 34. A deflector 39 is fixedly installed at the end of the power rod 34 to evenly distribute the airflow through the deflector 39.

[0049] Specifically, since the deflector 39 is fixedly installed at the end of the power rod 34, when the power rod 34 rotates, the deflector 39 is synchronously driven to rotate, and the gas flow direction is controlled through the deflector 39. The evenly distributed airflow can prevent the formation of eddy currents or local low air flow velocity regions in the channel, thereby reducing the pressure loss, maintaining the efficient operation of the main body 1, and avoiding blockage or uneven flow velocity caused by overly dense airflow in some areas.

[0050] The control device can select a single-chip microcomputer as the control terminal. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (Micro controller Unit), which is composed of an arithmetic unit, a controller, a memory, input and output devices, etc., and is equivalent to a miniature computer. Compared with the general-purpose microprocessor used in personal computers, it emphasizes more on self-supply (without external hardware) and cost savings. Its greatest advantage is its small size, which can be placed inside the instrument, but it has a small storage capacity, simple input and output interfaces, and low functional consumption.

[0051] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
