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 separated 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 a grounding trunk line and a temporary grounding line column separated in an explosion-proof clean area in view of the deficiencies in the prior art. The structure is simple, prevents dust collection, is convenient for later maintenance, has low installation and production costs, 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 a partition in an explosion-proof clean area, comprising a partition wall, a temporary grounding wire pole and a grounding trunk line, wherein the partition wall is made of double-layer color steel plates, a certain distance is left between the double-layer color steel plates, the grounding trunk line is arranged in the distance between the double-layer color steel plates, the grounding trunk line is laid along the bend inside the double-layer color steel plates, the bolts of the temporary grounding wire pole pass through the double-layer color steel plates and extend to the grounding trunk line, and the temporary grounding wire pole is fixedly connected to the grounding trunk line by bolts.

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

[0007] Furthermore, temporary grounding poles are provided on both sides of the double-layer color steel plate.

[0008] Furthermore, the grounding trunk line adopts a galvanized flat steel grounding trunk line.

[0009] Furthermore, the cross section of the double-layer color steel plate is groove-shaped.

[0010] The above technical solution has the following beneficial effects:

[0011] The utility model has a simple structure and utilizes the spacing between the double-layer color steel plates to install the grounding trunk line. The temporary grounding wire pole extends into the grounding trunk line through the color steel plates and is fixedly connected to the grounding trunk line, thereby hiding the grounding trunk line between the double-layer color steel plates, 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.

[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 a color steel plate, 2 is a temporary grounding wire pole, and 3 is a grounding trunk line. DETAILED DESCRIPTION Specific embodiment 1:

[0016] See also Figure 1 As shown, a mounting structure of a grounding trunk line and a temporary grounding wire pole for partitions in an explosion-proof clean area includes a partition wall, a temporary grounding wire pole and a grounding trunk line. The partition wall is a double-layer color steel plate, and a certain distance is left between the double-layer color steel plates, which can just accommodate the grounding trunk line. The grounding trunk line is arranged in the distance between the double-layer color steel plates, and the grounding trunk line is laid along the bend inside the double-layer color steel plate. The grounding trunk line adopts a galvanized flat steel grounding trunk line, and the galvanized flat steel grounding trunk line adopts a galvanized flat steel with a width*thickness of 40mm*4mm. The cross section of the double-layer color steel plate is a groove shape, that is, the bend of the grounding trunk line is in a groove shape, which is convenient for laying the grounding trunk line.

[0017] The temporary grounding wire post adopts a stainless steel terminal post, and the temporary grounding wire post includes bolts (M10*80), nuts and washers, and the bolts, nuts and washers are all made of stainless steel. The temporary grounding wire post is arranged on the outside of the double-layer color steel plate, and the bolts of the temporary grounding wire post extend through one side of the double-layer color steel plate to the grounding trunk line. The temporary grounding wire post is welded and fixed to the grounding trunk line by bolts. The bolts of the temporary grounding wire post are longer than the bolts of the existing temporary grounding wire post, ensuring that the bolts of the temporary grounding wire post can extend into the double-layer color steel plate and be fixedly connected to the grounding trunk line. In this specific embodiment: temporary grounding wire posts are provided on both sides of the double-layer color steel plate to facilitate wiring on both sides of the double-layer color steel plate.
