[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1

[0024] See also Figure 1-Figure 5 , which is the first embodiment of the utility model, and provides an embodiment of an airbag leak detection type oil storage cabinet, comprising a cabinet body 11, wherein the right end surface of the cabinet body 11 is provided with an oil inlet 12 connected to an external oil pump, and the lower end surface of the cabinet body 11 is fixedly provided with an air outlet pipe 14;

[0025] The cabinet 11 is provided with an internal storage cavity 20, in which an air-injected capsule 23 is fixedly provided. The air-injected capsule 23 can expand and contract, and a capsule cavity 27 is provided in the air-injected capsule 23. The air-injected capsule 23 is designed to be inclined, and a float 21 capable of moving up and down is provided in the internal storage cavity 20. The air outlet pipe 14 is provided with a detection cavity 25 connected to the capsule cavity 27, and the right wall of the detection cavity 25 and the right wall of the capsule cavity 27 are provided with an air outlet 16 and an air inlet 13 connected to an external air pump.

[0026] An air outlet on-off valve 26 is fixedly provided in the air outlet 16 , and the air outlet on-off valve 26 can control the on-off of the air outlet 16 . A filter frame 24 is fixedly provided in the air inlet 13 , and the filter frame 24 can filter air impurities.

[0027] The upper end surface of the cabinet 11 is fixedly provided with a meter 18 , and the lower end surface of the meter 18 is provided with a connecting spring 22 fixedly connected to the upper end surface of the float 21 . The meter 18 can display the oil level and oil pressure in the internal storage chamber 20 .

[0028] An air pressure detector 19 is fixedly provided on the lower wall of the detection cavity 25 , and the air pressure detector 19 can detect the air pressure change in the capsule cavity 27 .

[0029] The left wall of the internal storage chamber 20 is provided with an oil outlet 15 which is connected to an external liquid outlet pump.

[0030] An oil drain rack 28 is fixedly disposed on the right wall of the oil outlet 15 , and the right end surface of the oil drain rack 28 is made of elastic material.

[0031] A control panel 17 is fixedly disposed on the front end surface of the cabinet 11 , and the control panel 17 can control the start and stop of all valves and pumps of the utility model.

[0032] When performing oil storage work, the air inlet 13 is connected to the external air pump at the same time. The air pump filters the impurities from the external air through the filter frame 24 and then injects it into the capsule cavity 27, so that the gas-injected capsule 23 begins to expand. At this time, the air pressure detector 19 detects the air pressure change. After the gas-injected capsule 23 expands to an appropriate volume, the external oil is injected into the internal storage cavity 20 through the oil inlet 12. The oil level height is detected by the float 21, and the oil level is detected at the instrument 18. At the same time, the external air pump is connected to the air outlet 16 and started in reverse, so that the air in the capsule cavity 27 is discharged through the air outlet check valve 26, and the gas-injected capsule 23 begins to shrink until enough oil is stored in the internal storage cavity 20. At this time, the cabinet 11 can realize the storage work, and the air pressure detector 19 can detect the change of the air pressure in the capsule cavity 27 when the gas-injected capsule 23 is ruptured, so as to quickly judge the abnormal situation of the gas-injected capsule 23 being ruptured, thereby reducing the loss caused by the damage of the gas-injected capsule 23.

[0033] When the oil needs to be discharged, the capsule cavity 27 can be expanded by injecting air into the air inlet 13, and the oil outlet 15 can be connected to the external liquid outlet pump. With the expansion of the capsule cavity 27 and the operation of the external liquid outlet pump, the oil in the internal storage cavity 20 can be quickly discharged through the detection cavity 25. The elastic layer on the right end face of the oil drain rack 28 and the inclined design of the air injection capsule 23 can prevent the oil drain rack 28 and the air injection capsule 23 from being over-squeezed and causing the air injection capsule 23 to rupture. In addition, due to the inclined design of the air injection capsule 23, it can prevent the air injection capsule 23 from blocking the oil inlet 12 and the oil outlet 15 when expanding, resulting in a situation where the oil cannot be discharged or in.
