TECHNICAL FIELD
[0001] The utility model belongs to the technical field of static electricity release equipment relates to forced static electricity release device. BACKGROUND
[0002] In the petrochemical industry, oil products are prone to generate static electricity charges due to fluid friction, medium separation and other effects during transportation, stirring and loading and unloading. Especially in the storage tank area operation scene, personnel need to frequently go up to the tank top by escalator for sampling, maintenance and other operations. Due to the complex operation environment such as oil vapor gathering, exposed metal surface of equipment and human factors such as weak safety awareness and non-standard operation process, personnel often do not actively touch the traditional static electricity release pile or contact for a short time, resulting in ineffective discharge of human body static electricity. When the static electric field strength generated by the accumulated electric charge exceeds the minimum ignition energy of the oil and gas mixture, the electric spark generated by instantaneous discharge can ignite the leaked oil, causing a chain explosion accident.

Detailed Implementation
[0017] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0018] This utility model relates to a forced electrostatic discharge device, such as... Figure 1 As shown, the forced electrostatic discharge device is installed at the inlet and outlet channels of the tank area, including a first electrostatic discharge unit and a second electrostatic discharge unit arranged symmetrically. The first electrostatic discharge unit and the second electrostatic discharge unit are respectively fixed on both sides of the inlet and outlet channels of the tank area, and the first electrostatic discharge unit and the second electrostatic discharge unit are connected to the grounding wire 10.
[0019] The first electrostatic discharge unit includes a first railing 5, one end of which is fixed to one side of the inlet and outlet passage of the storage tank area, and a first bidirectional free hinge 3 is provided on the side wall of the other end of the first railing 5.
[0020] The first two-way free hinge 3 is connected with the first barrier 5 at one end away from the first barrier 5, and the first barrier 5 is rotationally connected with the first barrier 1 through the first two-way free hinge 3.
[0021] The first barrier 1 and the first barrier 5 are vertically arranged, and the first barrier 1 and the first barrier 5 are internally provided with the first connecting line 7.
[0022] The second static electricity releasing unit comprises a second barrier 6, one end of the second barrier 6 is fixed on the other side of the inlet and outlet passage of the storage tank area, and the other end of the second barrier 6 is provided with the second two-way free hinge 4 on the side wall.
[0023] The second two-way free hinge 4 is connected with the second barrier 2 at one end away from the second barrier 6, and the second barrier 2 is rotationally connected with the second barrier 6 through the second two-way free hinge 4.
[0024] The second barrier 2 and the second barrier 6 are vertically arranged, and the second barrier 2 and the second barrier 6 are internally provided with the second connecting line 8.
[0025] The first barrier 5 and the second barrier 6 are arranged on the two sides of the inlet and outlet passage of the storage tank area respectively, and the first barrier 1 and the second barrier 2 are oppositely arranged.
[0026] In the utility model, the first barrier 1, the second barrier 2, the first two-way free hinge 3, the second two-way free hinge 4, the first barrier 5, the second barrier 6, the first connecting line 7, the second connecting line 8, the bridge connecting line 9 and the grounding line 10 all adopt conductive materials.
[0027] The forced static electricity releasing device can be horizontally arranged on the road of the storage tank area, the first barrier 5 and the second barrier 6 are arranged on the two sides of the road respectively, the first barrier 1 and the second barrier 2 are arranged in the middle of the road and block the road of the storage tank area, when the staff enters the storage tank area, the first barrier 1 or the second barrier 2 needs to be pushed away to pass, and when the staff pushes away the first barrier 1 or the second barrier 2, the static electricity releasing can be completed by contacting the first barrier 1 or the second barrier 2, the charge carried by the human body is transferred to the bridge connecting line 9 and the grounding line 10 in sequence through the first connecting line 7 in the first barrier 1 or the second connecting line 8 in the second barrier 2 and finally transferred to the ground; when the staff leaves the storage tank area, the first barrier 1 or the second barrier 2 needs to be pushed away again to complete the static electricity releasing again, and the charge carried by the human body is transferred to the ground again.
[0028] This utility model adopts a dual forced release mechanism, breaking through the limitations of traditional one-way protection. It provides bidirectional interception for both entry and exit. The first stop bar 1, connected to the first bidirectional free hinge 3, and the second stop bar 2, connected to the second bidirectional free hinge 4, block the entry and exit channels. Whether personnel are entering the tank platform for work or leaving after completing their work, they must use a body part, such as their hand, to push the stop bar (pushing it inwards to enter, and pushing it outwards to leave). This design upgrades single-time electrostatic discharge to dual-time release for both entry and exit, completely eliminating the hidden danger of "static electricity generated by secondary friction during operation."
[0029] In this invention, either the first stop lever 1 or the second stop lever 2 is installed parallel to the ground at the bottom of the upper tank step, with a height adapted to the natural range of human arm movement (approximately 1.2-1.5 meters). Personnel must raise their hand to push the stop lever when entering or exiting the tank, forcing hand contact through biomechanical guidance. This avoids the "detour" or "perfunctory touch" problems that may exist with traditional column-type release devices, effectively improving the execution rate of electrostatic release operations. This invention establishes a strong conditioned reflex between pushing the stop lever and electrostatic release, achieving closed-loop operation control. Furthermore, the stop lever, with its rigid structure, blocks the path to the upper tank, forming a visible physical barrier. Personnel cannot pass without pushing the stop lever, spatially eliminating the possibility of "oversighted omissions," thus achieving dual reinforcement of behavioral norms and risk prevention.
[0030] This device upgrades electrostatic protection from a "passive reliance on human awareness" to an "active mechanical constraint" mode, taking into account explosion-proof safety, environmental durability, and economy. It provides a replicable solution for high-risk work scenarios and significantly reduces the risk of catastrophic accidents caused by static electricity.
