[0028] Further, the width of the sealing sleeve 211 is greater than that of the pushing block 29, so that the pushing block 29 can be pulled out of the oil tank body 1 to realize disassembly.

[0029] It is worth noting that the pressure switch 25 is electrically connected with the alarm mechanism 22, so that the signal can be transmitted to achieve the effect of alarm.

[0032] Wherein, the structure such as motor is prior art, no longer repeat; Meanwhile, the utility model still includes power, controller and switch etc., it is not the main technical point of this patent, no longer repeat. The motor wiring diagram in the utility model belongs to the public knowledge in the art, and its working principle is already known technology, and its model is selected according to actual use, so the motor is not explained in detail control mode and wiring arrangement.

[0033] Working principle and flow: when the gas in the oil storage tank body 1 leaks, the push block 29 is pushed by the pressure of the gas in the oil storage tank body 1, when the pressure of the gas in the oil storage tank body 1 decreases due to leakage, the reset spring one 210 is subjected to the thrust of the gas in the oil storage tank body 1, and the reset spring one 210 is reset, and the connecting disc 27 is driven to move down in the process of reset, and the connecting disc 27 drives the connecting rod 26 to slide in the sealing cavity 23 formed in the surface of the U-shaped plate 21, and the detection rod 28 at the bottom of the connecting disc 27 drives the push block 29 to move down in the oil storage tank body 1, and the sealing sleeve 211 sleeved on the surface of the detection rod 28 can seal the through hole formed in the surface of the oil storage tank body 1, so that the gas in the oil storage tank body 1 is prevented from leaking from the through hole, and the sealing effect of the oil storage tank body 1 is further improved, the connecting rod 26 drives the pressure plate 24 to move in the process of sliding, when the pressure plate 24 moves to the appropriate position, the pressure plate 24 extrudes the pressure switch 25, and the pressure switch 25 sends a signal to the alarm mechanism 22, so that the alarm mechanism 22 generates an alarm sound and a flashing light, so as to remind the staff that the gas in the oil storage tank body 1 leaks;

[0034] When the alarm mechanism 22 and the pressure switch 25 are damaged after long time use, the staff first pulls the plug rod 32 in the through hole on the surface of the mounting plate 31, at this time the plug rod 32 slides in the inside of the mounting plate 31, the plug rod 32 drives the reset spring two 33 to deform in the movement process, the reset spring two 33 can reset the moving position of the plug rod 32, so as to further improve the use effect of the device, at this time the plug rod 32 is separated from the plug hole on the surface of the oil tank body 1, at this time the staff pulls out the U-shaped plate 21, so that the U-shaped plate 21 is separated from the oil tank body 1, so as to realize the disassembly and replacement of the whole U-shaped plate 21, avoid the damage of the alarm mechanism 22 and the pressure switch 25 after long time use, affect the reminding effect of the gas leakage in the inside of the oil tank body 1.

[0035] It should be noted that: the alarm mechanism 22 and the pressure switch 25 are mature existing technology, by extruding the pressure switch 25, at this time the pressure switch 25 is extruded to transmit signals to the alarm mechanism 22, the alarm mechanism 22 receives the transmitted signals, so as to remind the staff by sound and flash.

[0036] It should be noted that: the pressure switch 25 adopts high-precision, high-stability pressure sensor and variable transmission circuit, and then adopts special CPU modular signal processing technology to realize detection, display, alarm and control signal output of medium pressure signal.

[0037] It should be noted that: the alarm mechanism 22 is an apparatus for issuing alarm signals. It is used to issue pre-alarm, alarm and alarm cancellation signals. The infrared transmitter drives the infrared emitting diode to emit a modulated infrared light beam. An infrared receiver is placed at a certain distance from the infrared transmitter and is aligned with it. It receives the infrared radiation energy found by the phototransistor and converts it into an electric signal through photoelectric conversion. The electric signal is sent to the alarm controller circuit after appropriate processing.

[0038] The optical system placed in the receiving and transmitting ends generally adopts optical lens, which plays a role in focusing the infrared light beam into a thin parallel light beam, so that the energy of the infrared light can be concentrated and transmitted. The infrared light is in the spectral range invisible to the human eye. If someone crosses this invisible blockade line, the infrared light beam will be completely or partially blocked. The strength of the electric signal output by the receiving end will change, thereby starting the alarm controller to issue an alarm signal. The infrared transmission type alarm has very high detection reliability.
