Description

Technical Field

[0001] The utility model belongs to the field of medicine and chemical industry, and specifically relates to an installation structure of a grounding trunk line and a temporary grounding wire column in an explosion-proof clean area. Background Art

[0002] There are many occasions in the clean workshop environment where static electricity hazards exist, which may cause damage or performance degradation of electronic devices and electronic instruments and equipment, or cause electric shock injuries to the human body, or cause explosions and fire hazards to ignite or detonate, or cause dust adsorption to affect the cleanliness of the environment. Therefore, in the design of clean workshop engineering, it is necessary to attach great importance to the anti-static environment design and set up explosion-proof areas. In order to facilitate the grounding of equipment in the explosion-proof area, a circle of grounding trunk lines are usually laid on the walls around the room and temporary grounding poles are set up. However, the explosion-proof clean area has higher requirements for the environment. The open laying of grounding trunk lines and temporary grounding poles in the room will collect dust above the grounding trunk lines and temporary grounding poles and is not easy to clean, affecting the cleanliness of the clean area. Especially in pharmaceutical plants, laboratories, etc., the grounding requirements and cleanliness requirements for explosion-proof clean areas are higher. Summary of the invention

[0003] The purpose of the utility model is to provide an installation structure for an explosion-proof clean area grounding trunk line and a temporary grounding wire column in view of the deficiencies in the prior art. The structure is simple, prevents dust collection, is convenient for later maintenance, has a low installation and production cost, and can meet the grounding requirements of explosion-proof clean areas.

[0004] The technical solution adopted by the purpose of the utility model is:

[0005] A mounting structure for a grounding trunk line and a temporary grounding wire pole in an explosion-proof clean area comprises an explosion-proof wall, a temporary grounding wire pole and a grounding trunk line, wherein a color steel plate is arranged on one side of the explosion-proof wall, a certain distance is left between the explosion-proof wall and the color steel plate, the grounding trunk line is arranged in the distance between the explosion-proof wall and the color steel plate, the grounding trunk line is fixed to the explosion-proof wall by screws, the temporary grounding wire pole is arranged on the side of the color steel plate, the bolts of the temporary grounding wire pole pass through the color steel plate and extend to the grounding trunk line, and the temporary grounding wire pole is fixedly connected to the grounding trunk line.

[0006] Furthermore, the temporary grounding wire post adopts a stainless steel terminal post.

[0007] Furthermore, the grounding trunk line adopts a galvanized flat steel grounding trunk line.

[0008] Furthermore, the galvanized flat steel grounding trunk line adopts galvanized flat steel with a width and thickness of 40mm*4mm.

[0009] The above technical solution has the following beneficial effects:

[0010] The utility model has a simple structure. The grounding trunk line is installed by utilizing the distance between the explosion-proof wall and the color steel plate. The temporary grounding wire pole extends into the grounding trunk line through the color steel plate and is fixedly connected to the grounding trunk line, thereby hiding the grounding trunk line between the explosion-proof wall and the color steel plate, effectively preventing dust collection and inconvenience in cleaning, facilitating later maintenance, and having low installation and production costs, and can meet the grounding requirements of explosion-proof clean areas.

[0011] The grounding trunk line adopts a galvanized flat steel grounding trunk line, which is convenient for setting the distance between the explosion-proof wall and the color steel plate, and is convenient for installing a temporary grounding wire column.

[0012] Further description is given below in conjunction with the accompanying drawings and specific implementation methods. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a structural schematic diagram of specific embodiment 1.

[0014] In the attached figure, 1 is an explosion-proof wall, 2 is a color steel plate, 3 is a grounding trunk line, 4 is a screw, and 5 is a temporary grounding wire column. DETAILED DESCRIPTION Specific embodiment 1:

[0016] See also Figure 1 As shown, a mounting structure for grounding trunks and temporary grounding poles in explosion-proof clean areas includes an explosion-proof wall, a temporary grounding pole and a grounding trunk. A color steel plate is provided on one side of the explosion-proof wall. A certain distance is left between the explosion-proof wall and the color steel plate, and the distance can just accommodate the grounding trunk. The grounding trunk is provided in the distance between the explosion-proof wall and the color steel plate, and the grounding trunk is fixed to the explosion-proof wall by screws. The galvanized flat steel grounding trunk adopts galvanized flat steel with a width and thickness of 40mm*4mm. The explosion-proof wall is a concrete solid brick reinforced wall, and the screws adopt No. 9 cement nails with a length of 38.1mm and a diameter of 3.76mm.

[0017] The temporary grounding wire post adopts a stainless steel terminal. The temporary grounding wire post includes a bolt (M10*80), a nut and a washer, and the bolt, nut and washer are all made of stainless steel. The temporary grounding wire post is arranged on the side of the color steel plate, and the bolt of the temporary grounding wire post passes through the color steel plate and extends to the grounding trunk line. The temporary grounding wire post is fixedly connected to the grounding trunk line by the bolt. The bolt of the temporary grounding wire post is longer than the bolt of the existing temporary grounding wire post, ensuring that it can be inserted into the color steel plate and fixed to the grounding trunk line.
