[0032] In an embodiment of the present utility model, as Figures 1-5 shown, there is provided an anti-static device for a natural gas storage tank, including a base 1 and a tank body 2. A fixed block 3 is fixedly installed on the side surface of the base 1, a conductive frame 4 is fixedly installed on the surface of the tank body 2, a ground wire 5 is fixedly installed on the side surface of the conductive frame 4, a maintenance frame 6 is fixedly installed on the upper surface of the tank body 2, a feed pipe 7 is fixedly installed on the side surface of the tank body 2, a pressure gauge 8 is fixedly installed on the side surface of the tank body 2, and a discharge valve 9 is fixedly installed on the side surface of the tank body 2. Both sides inside the base 1 are rotatably connected with lead screws 10. One ends of the lead screws 10 are respectively fixedly installed with a pulley A 11 and a pulley B 12. A transmission belt 13 is drivingly connected to the surfaces of the pulley A 11 and the pulley B 12. A motor 14 is fixedly installed on the side surface of the pulley B 12. A moving block 15 is slidably connected to the surface of the lead screw 10. A moving plate 16 is fixedly installed on the upper surface of the moving block 15. A limiting block 17 is slidably connected to the upper surface of the moving plate 16. By installing the conductive frame 4 and the ground wire 5 on the tank body 2, static electricity can be effectively conducted, preventing fires or explosions caused by static electricity accumulation and improving the safety of the natural gas storage tank. At the same time, the setting of the maintenance frame 6 facilitates the operator to perform daily maintenance and ensures the normal operation of the equipment.

[0033] As Figures 1-5 shown, the pulley A11 and the pulley B12 are rotatably connected to the base 1, the motor 14 is fixedly connected to the base 1, and the pulley A11 and the pulley B12 are connected to the motor 14 through the transmission belt 13, making the power transmission more stable, reducing the wear of mechanical components, and extending the service life of the equipment. In addition, the fixed connection between the motor 14 and the base 1 further enhances the stability of the device. The moving block 15 and the moving plate 16 are slidably connected to the base 1. The threads at both ends of the lead screw 10 are arranged in opposite directions. The sliding connection between the moving block 15 and the base 1 and the reverse setting of the threads of the lead screw 10 enable the moving block 15 to be flexibly adjusted in position on the lead screw 10, facilitating the precise adjustment and positioning of the storage tank, improving the operation convenience and accuracy of the equipment. The maintenance frame 6 is fixedly connected to the conductive frame 4, and the ground wire 5 is fixedly connected to the base 1. The fixed connection between the maintenance frame 6 and the conductive frame 4 and the fixed connection between the ground wire 5 and the base 1 ensure the stability and reliability of the conductive system, enabling static electricity to be effectively conducted in a timely manner, further enhancing the safety protection function of the storage tank. The inside of the limit block 17 is slidably connected with a clamping block 18. A connecting block 19 is fixedly installed on the side of the limit block 17. A positioning block 20 is fixedly installed on the side of the moving plate 16. The inside of the connecting block 19 is slidably connected with a connecting rod 21. The top of the connecting rod 21 is fixedly installed with a pulling head 22. A pulling spring 23 is fixedly installed on the lower surface of the pulling head 22. The connection of the clamping block 18 inside the limit block 17 and the positioning block 20 installed on the side of the moving plate 16 enables the moving device to have a precise limiting function, preventing excessive movement or misalignment, and improving the safety and stability during equipment operation. The clamping block 18 is fixedly connected to the moving plate 16. The connecting rod 21 is slidably connected to the positioning block 20. One end of the pulling spring 23 is fixedly connected to the connecting block 19. The setting of the pulling spring 23 provides a reset function, ensuring that the moving components can quickly return to the initial position after the operation of the pulling head 22 and the connecting rod 21, further improving the operation efficiency of the device and reducing the loss of mechanical components.

[0034] At least one of the above embodiments of the present utility model can at least achieve the following: First, place the conductive frame 4 on the surface of the tank body 2 for installation, then move the tank body 2 to the base 1. When the motor 14 drives the pulley B12 to rotate, the pulley B12 can drive the transmission belt 13 and the pulley A11 to rotate, so that the lead screw 10 rotates smoothly inside the base 1. By the rotation of the lead screw 10, the moving block 15 can move, and the moving block 15 drives the moving plate 16 to move, so that the moving block 15 drives the limiting block 17 to move to the position of the tank body 2, so that the tank body 2 is clamped and installed. Then connect the ground wire 5 to the ground to play a role in conducting electricity and reduce the generation of static electricity. Natural gas can be injected into the interior through the position of the feed pipe 7, and the pressure inside can be detected through the position of the pressure gauge 8. When it is necessary to discharge the natural gas, it can be discharged through the position of the discharge valve 9. When the limiting block 17 is damaged or aged, the pull head 22 can be grasped and pulled, so that the pull head 22 drives the connecting rod 21 to move, and the connecting rod 21 slides out of the positioning block 20. Then the limiting block 17 can be grasped and pulled, so that the limiting block 17 slides out of the clamping block 18. Then the limiting block 17 is aligned with the positions of the clamping block 18 and the moving plate 16 and pushed, so that the limiting block 17 slides to the position of the clamping block 18. When the limiting block 17 slides to a suitable position, the connecting rod 21 can be driven by the tension spring 23 to slide from the inside of the connecting block 19 to the position of the positioning block 20, so that the limiting block 17 is clamped and limited.

[0035] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
