Description

Technical Field

[0001] The utility model relates to the technical field of liquid oxygen storage tanks, in particular to an overload automatic pressure relief alarm liquid oxygen storage tank. Background Art

[0002] Liquid oxygen storage tanks are a type of device specifically designed to store liquid oxygen. They can store liquid oxygen to meet high flow requirements that oxygen cylinders cannot meet. Liquid oxygen storage tanks are made of double-walled compression, with the inner layer being a gas container made of stainless steel and the outer layer being insulation material to prevent heat loss. Liquid oxygen storage tanks can store oxygen in a liquefied form, reducing the volume for easy transportation and storage, while also providing a longer supply of medical oxygen.

[0003] After searching, the publication number is: CN214663676U, which discloses an overload automatic pressure relief alarm liquid oxygen storage tank. When the liquid oxygen in the liquid oxygen storage tank is full and the user continues to inflate it, the liquid oxygen flows from the exhaust pipe 2 to the buffer zone. When there is too much liquid oxygen in the buffer zone, the pressure increases, and the blocking block is pushed through the through hole. The blocking block slides out of the blocking port and moves in the exhaust pipe 1, and the liquid oxygen enters the exhaust pipe 1, and then enters the pressure relief pipe from the exhaust pipe 1 to relieve the pressure. Since the temperature of the liquid oxygen is low, the temperature sensor can detect the low temperature and transmit the signal to the alarm, sounding an alarm, and reminding the staff to stop inflating. However, the liquid oxygen storage tank in the above-mentioned prior art does not have a stabilizing mechanism, and the liquid oxygen storage tank cannot be placed on an uneven ground, and the stability of the liquid oxygen storage tank is poor.

[0004] In order to solve the above problems, the utility model proposes a liquid oxygen storage tank with automatic overload pressure relief alarm. Utility Model Content

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the utility model, rather than implying that each embodiment of the utility model must have the described feature. In addition, it should be noted that this specification describes many features. Although some features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0024] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments:

[0025] refer to Figure 1-4 A liquid oxygen storage tank with automatic overload pressure relief alarm comprises a No. 1 seat 1 and a No. 2 seat 2. A clamping groove 7 is provided on the side walls opposite to the No. 1 seat 1 and the No. 2 seat 2.

A liquid oxygen storage tank body 9 is provided between the two clamping arc plates 8.

[0026] When it is necessary to stabilize the liquid oxygen storage tank body 9, the liquid oxygen storage tank body 9 is placed between the No. 1 seat 1 and the No. 2 seat 2, then the No. 1 seat 1 and the No. 2 seat 2 are spliced ​​together and the two threaded grooves 3 are matched with the two threaded holes 4, and then two fixing bolts 5 are respectively threaded into the threaded grooves 3 from one side of the threaded holes 4 to achieve a threaded fixed connection between the No. 1 seat 1 and the No. 2 seat 2, and then the lower end of the liquid oxygen storage tank body 9 is separated from the ground and the two clamping cylinders 6 are started at the same time, and the telescopic ends of the two clamping cylinders 6 respectively push the two clamping arc plates 8 to move relatively to contact the side walls of the liquid oxygen storage tank body 9, so that the two clamping arc plates 8 are against the side walls of the liquid oxygen storage tank body 9 and the liquid oxygen storage tank body 9 is firmly limited between the No. 1 seat 1 and the No. 2 seat 2, thereby improving the stability of the liquid oxygen storage tank body 9 on the ground;

[0027] Furthermore, the two clamping arc plates 8 are slidably connected to the inner walls of the two clamping grooves 7 respectively.

[0028] By making the two clamping arc plates 8 slidably connected to the inner walls of the two clamping grooves 7 respectively, the two clamping arc plates 8 can slide along the inner walls of the two clamping grooves 7 respectively;

[0029] Furthermore, the two opposite sides of the two clamping arc plates 8 are provided with an anti-skid layer, the anti-skid layer is provided with anti-skid patterns, and the anti-skid layer is a rubber block.

[0030] By providing an anti-skid layer, when the two clamping arc plates 8 are against the side wall of the liquid oxygen storage tank body 9, the anti-skid layer can increase the friction between the liquid oxygen storage tank body 9 and the surface of the liquid oxygen storage tank body 9, so that the liquid oxygen storage tank body 9 is not easy to fall off from between the two clamping arc plates 8. At the same time, since the anti-skid layer is a rubber block, the wear on the surface of the liquid oxygen storage tank body 9 when the liquid oxygen storage tank body 9 is limited can be reduced;

[0031] Furthermore, the two fixing bolts 5 match the threads of the two thread grooves 3 and the threaded holes 4 respectively.

[0033] Furthermore, two locking universal wheels 10 are provided on the lower end surfaces of the No. 1 seat 1 and the No. 2 seat 2 .

[0034] By setting the locking universal wheels 10, when the first seat 1 and the second seat 2 complete the position limiting and stabilization of the liquid oxygen storage tank body 9, the first seat 1 and the second seat 2 can be moved on the ground with the help of four locking universal wheels 10, making the movement and transportation of the liquid oxygen storage tank body 9 more convenient;

[0035] Furthermore, an air inlet 11 is fixedly connected to the liquid oxygen storage tank body 9, a vent pipe 12 is fixedly connected to the liquid oxygen storage tank body 9, an alarm 13 is fixedly installed on the side wall of the vent pipe 12, a temperature sensor is arranged in the vent pipe 12, and the temperature sensor is electrically connected to the alarm 13.

[0036] By electrically connecting the temperature sensor to the alarm 13, when the temperature of the gas in the gas release pipe 12 exceeds a certain value, the temperature sensor will activate the alarm 13 through an electrical signal to remind the staff;

[0037] Furthermore, the manufacturer of the holding cylinder 6 is Yueqing Shenwei Pneumatic Co., Ltd., and the model is BSC300X;
