DETAILED DESCRIPTION
[0020] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.
[0021] A chemical refrigerant storage device, such as Figure 1-Figure 5 As shown, it includes a tank body 1 and a support frame 2. The support frame 2 is provided at the bottom of the tank body 1. An insulation layer is provided on the inner wall of the tank body 1. The insulation layer is made of polyurethane material. The insulation layer can reduce heat transfer, keep the temperature of the refrigerant in the tank body 1 stable, and ensure the storage quality of the refrigerant. A pressure relief pipe 3 is provided on the right side of the tank body 1. A guide pipe 4 is fixedly connected to the left end of the pressure relief pipe 3. The guide pipe 4 is located in the tank body 1. A piston rod 5 is slidably connected in the guide pipe 4. The piston at the left end of the piston rod 5 fits with the left opening of the guide pipe 4. A sliding groove 401 is opened on the left side of the guide pipe 4. The sliding groove 401 is larger than the left opening of the guide pipe 4. A plurality of pressure relief holes 403 are provided on the right side of the movable groove 401, a sealing groove 402 is opened on the right side inside the guide tube 4, a sealing rubber ring 6 is sleeved on the outer side of the piston rod 5, the sealing groove 402 fits with the sealing rubber ring 6, a first spring 7 is connected to the right end of the piston rod 5, a connecting block 8 is fixedly connected to the right end of the pressure relief pipe 3, and the left end of the connecting block 8 is connected to the piston rod 5 through the first spring 7, an inlet and outlet liquid pipe 16 is provided on the top of the tank body 1, and an electromagnetic valve 17 is sleeved on the outer side of the inlet and outlet liquid pipe 16, and the refrigerant can be extracted or sent into the tank body 1 through the inlet and outlet liquid pipe 16, and the electromagnetic valve 17 is closed after the operation is completed to ensure the sealing of the tank body 1.
[0022] like Figure 5 As shown, it also includes a distance sensor 9, a control panel 10 and an alarm 11. The distance sensor 9 is provided at the left end of the connecting block 8, and the control panel 10 and the alarm 11 are provided at the right end of the connecting block 8. The alarm 11 and the distance sensor 9 are both connected to the control panel 10 with electrical signals.
[0023] like Figure 6As shown, it also includes a mounting plate 13, a connecting rod 14 and a second spring 15. A connecting rod 14 is provided on the top of the support frame 2, a mounting plate 13 is provided at the bottom of the tank body 1, and a plurality of connecting rods 14 are provided on the mounting plate 13. The connecting rod 14 passes through the mounting plate 13, and a second spring 15 is sleeved on the outer side of the connecting rod 14. The second spring 15 is connected between the bottom of the mounting plate 13 and the top of the support frame 2. During transportation, the vibration of the vehicle will be transmitted to the support frame 2, and the support frame 2 will transmit the vibration to the second spring 15 through the connecting rod 14. The second spring 15 undergoes elastic deformation to absorb and store part of the energy, and then slowly releases the energy, thereby effectively reducing the vibration amplitude transmitted to the tank body 1 and reducing damage to the tank body 1.
[0024] like Figure 6 As shown, an anti-skid rubber pad 12 is also included. The bottom of the support frame 2 is provided with an anti-skid rubber pad 12. The anti-skid rubber pad 12 can increase the friction between the support frame 2 and the ground to prevent the device from sliding during use.
[0025] like Figure 1 As shown, a magnetic flap liquid level gauge 18 is also included. The top of the tank body 1 is provided with a magnetic flap liquid level gauge 18. The magnetic flap liquid level gauge 18 can monitor the liquid level height of the refrigerant in the tank body 1 in real time and provide an intuitive liquid level display.
[0026] Under normal operating conditions, the pressure in the tank body 1 is maintained within a safe range. At this time, the piston rod 5 drives the sealing rubber ring 6 to be embedded in the sealing groove 402 under the action of the first spring 7 to ensure the sealing of the tank body 1; when the pressure in the tank body 1 increases due to temperature rise or other reasons, the pressure inside the tank body 1 will push the piston rod 5 to move to the right. When the piston rod 5 moves to the opening on the left side of the piston disengages from the guide tube 4, the pressure relief hole 403 in the guide tube 4 is exposed, and the high-pressure gas or liquid refrigerant in the tank body 1 enters the pressure relief pipe 3 through the pressure relief hole 403 and is released to the outside, thereby reducing the pressure in the tank body 1 and avoiding potential dangers caused by overpressure; while the piston rod 5 moves to the right, the distance sensor 9 detects the distance between the connecting block 8 and the piston rod 5 in real time and feeds it back to the control panel 10. When the distance value reaches the preset value, the control panel 10 will control the alarm 11 to start, reminding the staff to pay attention and take action.
[0027] The above embodiments are provided for persons familiar with the art to implement or use the present invention. Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the utility model concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope of the innovative features mentioned in the claims.
