[0015] Compared with existing technologies, the refrigeration depressurization device for a high-pressure refrigerant storage tank provided by this utility model has the following advantages:

[0016] 1. This device, through the setting of moving parts and the cooperation of lead screw and nut seat, can drive the tray to move up and down. When it is necessary to remove the high-pressure storage tank body, the tray can be moved upward to remove the storage tank from the box, which is convenient for replacement, maintenance and other operations. At the same time, when it is necessary to put the storage tank in, the tray can be lowered to a suitable position for easy placement, which improves the convenience of use.

[0017] 2. The device uses a fixed component and an arc-shaped clamp to hold the high-pressure storage tank body, which can effectively prevent the tank from shaking or shifting during the operation of the device, ensuring its positional stability. It also makes it easy for staff to release the high-pressure storage tank body for easy removal. At the same time, the arc-shaped clamp can clamp according to the shape of the storage tank, which can adapt to high-pressure storage tank bodies of different specifications, improving the versatility of the device. Automatic clamping can be achieved through the push component, which is convenient and quick.

[0018] 3. The device, through the setting of limiting components, uses a hand-tightened bolt and a T-shaped rod to fix the double-headed electric push rod, preventing it from moving due to external forces or other factors during use. This ensures that the arc-shaped clamping plate maintains a stable clamping state on the high-pressure storage tank body. Furthermore, when fixing high-pressure storage tank bodies of different heights, rotating the hand-tightened bolt downwards pushes the double-headed electric push rod, thereby moving the arc-shaped clamping plate downwards simultaneously until the required height is reached, thus adapting to the height of the high-pressure storage tank body that needs to be fixed.

[0032] See appendix Figure 1-4 As shown in the figure, a refrigeration depressurization device for a high-pressure refrigerant storage tank according to an embodiment of the present invention includes a housing 100. The interior of the housing 100 is provided with a tray 302 for supporting the high-pressure storage tank body 101. A movable component is provided on one inner wall of the housing 100 to move the tray 302 upward so as to move the high-pressure storage tank body 101 out of the housing 100. A fixing component is provided on the upper part of the movable component for fixing the high-pressure storage tank body 101. A refrigeration component is provided on the outer side of the housing 100 for refrigerating and depressurizing the high-pressure storage tank body.

[0033] The movable component includes a circular groove 102 formed on the inner left side surface of the housing 100 and extending along its height. A lead screw 303 is rotatably connected to the inner cavity of the circular groove 102. A nut seat 300 is threaded onto the surface of the lead screw 303. A connecting plate 301 is fixedly connected to one end of the nut seat 300. The end of the connecting plate 301 is fixedly connected to the surface of the tray 302. A drive motor 309 is fixedly connected to the bottom left side of the housing 100. The output shaft of the drive motor 309 extends upward into the inner cavity of the circular groove 102 and is keyed to the end of the lead screw 303. Through the movable component and the cooperation between the lead screw 303 and the nut seat 300, the above solution allows the tray 302 to move up and down. When it is necessary to remove the high-pressure storage tank body 101, the tray 302 can be moved upward to remove the storage tank from the housing 100, facilitating replacement, maintenance, and other operations. Conversely, when it is necessary to place the storage tank, the tray 302 can be lowered to a suitable position for easy placement, improving usability.

[0034] The fastener includes a support strip 304 disposed on the top of the connecting plate 301. A strip-shaped hole 308 extending along the height is formed on the upper right surface of the support strip 304. A connecting strip 411 is slidably connected to the inner cavity of the strip-shaped hole 308. An I-shaped plate 408 is disposed on the upper right side of the support strip 304. The end of the I-shaped plate 408 is fixedly connected to the end of the connecting strip 411. Fixing rods 409 are fixedly connected to both sides of the I-shaped plate 408. Two sets of fixing rods 409... The surface of each high-pressure storage tank 101 is fitted with a fixing ring 410. Two sets of fixing rings 410 are fixedly connected to opposite sides with arc-shaped clamping plates 400. The openings of the two sets of arc-shaped clamping plates 400 are arranged opposite each other. A square hole 305 is provided on the upper front side of the support bar 304. A pushing component is provided inside the square hole 305 to simultaneously push the arc-shaped clamping plates 400 inward, thereby clamping the high-pressure storage tank body 101. A limiting component is provided at the top of the support bar 304 to fix the pushing component. The arc-shaped clamping plates 400 clamp the high-pressure storage tank body 101, effectively preventing it from shaking or shifting during operation, ensuring its stable position, and facilitating the release of the high-pressure storage tank body 101 by personnel for easy removal. The arc-shaped clamping plates 400 can clamp according to the shape of the storage tank, adapting to different specifications of high-pressure storage tank bodies 101, improving the versatility of the device. Automatic clamping can be achieved through the pushing component, making it convenient and quick.

[0035] The pushing component includes a double-headed electric push rod 404 that slides vertically within the cavity of a square hole 305. A connecting strip 411 located inside a strip-shaped hole 308 has its end fixedly connected to the surface of the double-headed electric push rod 404. Two sets of telescopic ends of the double-headed electric push rod 404 are fixedly connected to fixed discs 403. Circular columns 402 are fixedly connected to the tops of the two sets of fixed discs 403. Square rings 401 are provided on the surfaces of the two sets of circular columns 402. The ends of the two sets of square rings 401 are respectively fixedly connected to the center of the back of the corresponding side arc-shaped clamping plates 400. By using the double-headed electric push rod 404, the arc-shaped clamping plates 400 on both sides can be pushed inward synchronously through electric control, allowing for precise control of the clamping force and ensuring effective fixation of the high-pressure storage tank body 101.

[0036] The model number of the double-headed electric linear actuator 404 can be Delixi CDZDT-20, with a waterproof rating of IP65.

[0037] The limiting component includes a hand-tightening bolt 405 threaded to the top of the support bar 304, and a U-shaped frame 406 fixedly connected to the top of the double-headed electric push rod 404. A T-shaped rod 407 is rotatably connected to the inner cavity of the U-shaped frame 406. The small end of the T-shaped rod 407 rotates upward and passes through the U-shaped frame 406. The end of the hand-tightening bolt 405 extends downward to the inner cavity of the strip hole 308 and is fixedly connected to the small end of the T-shaped rod 407. The hand-tightening bolt 405, in conjunction with the T-shaped rod 407, can fix the double-headed electric push rod 404, preventing it from moving due to external forces or other factors during use. This ensures that the arc-shaped clamping plate 400 maintains a stable clamping position on the high-pressure storage tank body 101. Furthermore, when fixing the high-pressure storage tank body 101 at different heights, the hand-tightening bolt 405 is rotated downwards to push the double-headed electric push rod 404, thereby simultaneously moving the arc-shaped clamping plate 400 downwards until the required height is reached, thus adapting to the height of the high-pressure storage tank body 101 that needs to be fixed.

[0038] The refrigeration assembly includes a liquid heat-conducting layer 205 disposed inside the housing 100. Cooling plates 200 are embedded in the upper parts of both the front and rear sides of the housing 100. The cooling ends of the cooling plates 200 extend into the inner cavity of the housing 100, thereby enabling them to cool the liquid heat-conducting layer 205. A temperature controller 203 and a DSP controller 204 are respectively disposed on the front side of the housing 100. The cooling plates 200 are controlled by the temperature controller 203. The signal input terminal of the temperature controller 203 is electrically connected to the signal input terminal of the DSP controller 204 via wires. The output terminal of the drive motor 309 is controlled by the DSP controller 204. An operation panel 202 is located on the front of the housing 100. The signal output terminal of the operation panel 202 is electrically connected to the signal input terminal of the DSP controller 204 via a wire. A temperature sensor 201 is located on the front of the housing 100. The sensing end of the temperature sensor 201 extends into the interior of the housing 100 to monitor the temperature of the liquid heat-conducting layer 205. The signal output terminal of the temperature sensor 201 is electrically connected to the signal input terminal of the temperature controller 203 via a wire. The combination of the liquid heat-conducting layer 205 and the cooling element 200 effectively transfers cold energy, uniformly cooling the high-pressure storage tank body 101. The configuration of the temperature controller 203, DSP controller, temperature sensor 201, and operation panel 202 enables automatic temperature monitoring and precise control. The operating state of the cooling element 200 can be adjusted according to actual needs, ensuring a safe, stable, and efficient freezing and depressurization process, while also facilitating user operation and parameter setting.

[0039] The liquid thermal conductive layer 205 is one or more of ethylene glycol aqueous solution, silicone oil, and thermal conductive oil combined together.

[0040] The DSP controller 204 can be a TMS320F2812, the temperature sensor 201 can be a pt100, and the temperature controller 203 can be an Omron E5CC series. The thermostat 200 can be a TEC1-12703T125.

[0041] The top of the tray 302 is provided with a groove 307 for accommodating the high-pressure storage tank body 101. The groove 307 on the top of the tray 302 can be adapted to the shape of the high-pressure storage tank body 101, playing a positioning and limiting role. It can prevent the storage tank from shifting on the tray 302, ensuring that the storage tank is placed stably, and providing a good foundation for subsequent fixing and freezing depressurization operations.

[0042] The top of the tray 302 is provided with several sets of water-permeable holes 306. Through the opening of the water-permeable holes 306, any liquid that may be generated can be discharged smoothly, avoiding the accumulation of liquid on the tray 302, thereby reducing the resistance encountered by the tray 302 when it moves upward.

[0043] In use, the high-pressure storage tank body 101 is placed in the groove 307 on the top of the tray 302, and its placement is ensured to be stable. Then, the double-headed electric push rod 404 is activated. The double-headed electric push rod 404 slides up and down in the strip hole 308. Its telescopic end pushes the fixing plate 403. The fixing plate 403 drives the circular column 402 to move. The circular column 402 pushes the arc-shaped clamping plate 400 to move inward through the square ring 401, thereby clamping and fixing the high-pressure storage tank body 101.

[0044] When fixing the high-pressure storage tank body 101 at different heights, rotate the hand-tightening bolt 405 downwards to push the double-headed electric push rod 404, thereby moving the arc-shaped clamp 400 downwards simultaneously until the required height is reached, thus adapting to the height of the high-pressure storage tank body 101 that needs to be fixed.

[0045] The operator sends a command to the DSP controller 204 via the operation screen 202. After receiving the signal, the DSP controller 204 controls the drive motor 309 to start. The output shaft of the drive motor 309 rotates, which drives the lead screw 303 in the circular groove 102 to rotate. The nut seat 300, which is threadedly connected to the lead screw 303, moves downward along the lead screw 303. Then, through the connecting plate 301, it drives the tray 302 and the high-pressure storage tank body 101 to move downward, so that the high-pressure storage tank body 101 sinks into the box 100.

[0046] Temperature sensor 201 monitors the temperature of liquid heat-conducting layer 205 inside the housing 100 in real time and transmits the temperature signal to temperature controller 203. Furthermore, according to actual needs, the target temperature is set through operation panel 202. Operation panel 202 transmits the signal to DSP controller 204, which then controls temperature controller 203. Temperature controller 203 controls the start of cooling chip 200 based on the received signal. Cooling chip 200 cools the liquid heat-conducting layer 205 inside the housing 100 to achieve cooling and depressurization of high-pressure storage tank body 101.

[0047] During the cooling and depressurization process, the temperature sensor 201 continuously monitors the temperature of the liquid heat-conducting layer 205. If the temperature deviates from the set value, the temperature sensor 201 will send a signal to the temperature controller 203. The temperature controller 203 will automatically adjust the working state of the cooling chip 200 to keep the temperature of the liquid heat-conducting layer 205 within the set range, ensuring that the depressurization process proceeds stably.

[0048] After the pressure reduction is completed, the high-pressure storage tank body 101 is removed. The DSP controller 204 is controlled by the operation panel 202 to reverse the drive motor 309, which drives the tray 302 and the high-pressure storage tank body 101 to move upward until the storage tank returns to the upper part of the box 100. Then, the double-headed electric push rod 404 is activated, which drives the arc-shaped clamp 400 to move outward, releasing the high-pressure storage tank body 101. Finally, the operator removes the storage tank from the groove 307 of the tray 302.

[0049] The foregoing has shown and described the basic principles of the present invention. The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only illustrative of the principles of the present invention. Any modifications, equivalent substitutions, and improvements made within the scope of the present invention without departing from the scope of the present invention should be included within the protection scope of the present invention.
