[0022] An electrostatic conduction alarm mechanism 200 is fixedly provided on the outside of the support mechanism 100. The electrostatic conduction alarm mechanism 200 includes an alarm device 201 and a grounding wire clamp 204. The alarm device 201 is fixedly provided at the top of the support mechanism 100. An explosion-proof button switch 202 is fixedly provided on the front of the alarm device 201. A liquid crystal display screen for displaying data is fixedly provided on the front of the alarm device 201. A cable 203 is fixedly provided between the grounding wire clamp 204 and the alarm device 201. The grounding wire clamp 204 is made of stainless steel and alloy steel, and the surface is fluorocarbon coated. It has the functions of high temperature resistance and corrosion resistance, is not easy to rust and corrode, and has a long service life.

[0023] Specific reference Figure 1 and Figure 2, the alarm instrument 201 is an AESDYD-1 type intelligent static conductive grounding alarm instrument, which is an intuitive static protector suitable for gas stations and oil depots. By performing static grounding on the detected device, the alarm instrument 201 can monitor the digital display status of the grounding resistance value in real time, so as to ensure the continuity of the static grounding of the detected device during operation. The alarm instrument 201 has the function of real-time broadcasting of the grounding resistance value by sound, light and voice, which can conveniently and timely ensure the static discharge of the detected equipment during operation. When the grounding is poor or disconnected, the alarm is sounded and the warning light is raised, so that the staff can find the problem of the detected device in time and solve the problem in time to ensure the safety of the device.

In order to ensure the normal use of the alarm 201, the setting of the explosion-proof button switch 202 on the alarm 201 makes it easy to ensure that the resistance value of each operation is within the safe value, which effectively improves the safety of the operation. The cable 203 is used for the electrical connection between the alarm 201 and the grounding clamp 204. The grounding clamp 204 is mainly used to provide the alarm 201 with a grounding resistance signal. When in use, the static charge derived from the monitored device by the grounding clamp 204 is introduced into the ground through the vehicle's static grounding belt for discharge, and the grounding resistance data signal is transmitted to the alarm 201. The LCD screen of the alarm 201 displays the monitored value at that time. The grounding clamp 204 is made of stainless steel 304, which has high hardness and excellent antioxidant and conductive properties. The front end of the clamp is alloy steel that has been quenched to form a paint-breaking pin with a hardness of HRC40 to break paint and rust and oil stains. It has strong penetrating ability, which is conducive to ensuring that the monitored device is well grounded.

[0024] Specific reference Figure 1 and Figure 2, the alarm instrument 201 can be divided into three states, standby state, normal monitoring state and grounding alarm state. In the standby state, by removing the grounding clamp 204 from the clamping position, the alarm instrument 201 will be transformed into the grounding alarm state, and the grounding clamp 204 will be clamped on the monitored device and the clamp will be adjusted so that the alarm instrument 201 system is in the normal monitoring state. At the same time, this state is regarded as the electrostatic grounding of the alarm instrument 201 is good, and the oil filling operation can be carried out. After the operation is completed, the grounding clamp 204 is removed from the monitored device and put back into the clamping position. The alarm instrument 201 will be in the standby state again, so that Use it again, and during the above process, when in standby mode, the alarm instrument 201 voice prompts that the line is connected, the sound and light lights go out, and the resistance value is displayed as zero at this time. When in normal monitoring mode, the grounding wire clamp 204 is separated from the clamping position, and the voice prompt line is disconnected. The sound and light alarm causes the display screen to display text for reminder. In the grounding alarm state, the voice prompt line is connected, the sound and light lights go out, and the grounding resistance value is displayed. Furthermore, when the grounding line has poor grounding, the alarm instrument 201 will alarm, and a text prompt will appear on the display screen to inform personnel to check the line and equipment immediately.

[0025] The support mechanism 100 is internally movable and is provided with a cable 203 recovery mechanism 300. The recovery mechanism 300 includes a recovery roller 301 and a turning handle 302. The recovery roller 301 is rotatably arranged inside the support frame 101. The recovery roller 301 is used for reeling and unreeling the cable 203. The turning handle 302 is fixed to one end of the recovery roller 301. The turning handle 302 is used to control the rotation of the recovery roller 301. The turning handle 302 is L-shaped, and a rubber sleeve is fixedly provided on the outer wall of the turning handle 302. The recovery mechanism 300 also includes a wire board 303. The wire board 303 is fixedly arranged inside the support frame 101 and is located on the front of the recovery roller 301. A strip groove for the cable 203 to pass through is opened in the middle of the wire board 303.

[0026] Specific reference Figure 1 and Figure 2The setting of the recycling roller 301 allows the cable 203 to be wound along the outer wall of the recycling roller 301, so that the cable 203 can have a good storage space. At the same time, the rotation of the recycling roller 301 can quickly complete the winding of the cable 203, so that the alarm device 201 can be quickly stored after use, effectively improving the convenience and efficiency of the storage and use of the static electricity alarm mechanism 200. The setting of the wire plate 303 allows the cable 203 to pass through the inner cavity of the strip groove and be fixedly connected to the grounding clamp 204, so that the cable 203 is limited in its movement range during the winding and unwinding process, thereby avoiding the cable 203 from being in contact with the support mechanism 100 or the static electricity alarm mechanism 200. 00 does not produce entanglement and other phenomena, which effectively improves the orderliness of the cable 203 being wound and unwound, and at the same time, a turning handle 302 is fixedly set at one end of the recycling roller 301, so as to better control the rotation of the recycling roller 301, and at the same time, the outer wall of the turning handle 302 is also used for clamping and placing the grounding wire clamp 204, providing a structural support for storing the grounding wire clamp 204, when the grounding wire clamp 204 is clamped on the turning handle 302, the end is in an expanded state, and after the grounding wire clamp 204 is removed from the turning handle 302, the end is in a closed state, so that it can be adapted to the standby state and the grounding alarm state of the alarm device 201, and the setting of the turning handle 302 improves the convenience of taking or placing the grounding wire clamp 204.

[0027] In summary, the scope of application of the entire device is not only in civil aviation airport operations, but also can be used in fuel oil loading systems (including railway tank trucks, road tank trucks loading), liquid benzene, hydrocarbon sealed loading and other chemical product tanking systems. The alarm 201 is different from the existing static conductive alarm structure and can monitor the digital display status of the grounding resistance value in real time. The grounding wire clamp 204 is different from the existing static clamp. The safety prompt of the alarm 201 can be obtained through the clamping state of the grounding wire clamp 204, ensuring that the grounding resistance value reaches the national safety standard range of 0-10 ohms. At the same time, the cable 203 is different from the existing cable in the state where the resistance value will change during the retraction operation, so that the cable 203 cooperates with the grounding wire clamp 204 to ensure the stability of the resistance value when winding, effectively improving the safety of the cable 203 winding.
