The conductive column 1 and the static conductor 3 are both made of metal, and a conductive wire 11 for grounding is connected to the circumferential surface of the conductive column 1. Four fixing holes 21 for bolts to penetrate are formed in the supporting plate 2, so that the conductive upright column 1 is fixed on the ground. Four reinforcing ribs 22 fixedly connected with the supporting disc 2 are arranged on the circumferential surface of the lower end of the conductive upright post 1, so that the fixing stability of the conductive upright post 1 is improved.

As shown in fig. 2 and 3, the conductive pillar 1 is provided with a rectangular housing 4, and the static conductive member 3 is disposed in the housing 4. The housing 4 includes a bottom plate 41 fixedly connected to the conductive pillar 1, and an upper case 42 detachably connected to the bottom plate 41. The plane of the bottom plate 41 is perpendicular to the axis 1 of the conductive column, four elastic sheets 411 are vertically and fixedly connected to the upper surface of the bottom plate 41, each elastic sheet 411 is respectively arranged at the edge of the bottom plate 41, and the elastic sheets 411 are flush with the edge of the bottom plate 41. A latch 412 is fixedly connected to one side of the elastic sheet 411 facing the center of the bottom plate 41, the latch 412 is horizontally disposed, the longitudinal section of the latch 412 is triangular, and the bottom surface of the latch 412 is horizontally disposed. The outer side wall of the upper shell 42 is provided with an embedding hole 421 for accommodating the fixture block 412, and the fixture block 412 and the embedding hole 421 are matched with each other, so that the bottom plate 41 and the upper shell 42 are fixed more stably. By detaching the bottom plate 41 from the upper case 42, the damaged upper case 42 can be easily replaced, and the electrostatic conductive member 3 can be easily maintained.

As shown in fig. 2 and 3, when the upper shell 42 and the bottom plate 41 are detached from each other, the elastic piece 411 needs to be pulled away from the insertion hole 421, so that the elastic piece 411 is elastically deformed, and the fixture block 412 is also separated from the insertion hole 421, thereby facilitating the detachment of the bottom plate 41 and the upper shell 42 from each other; when the upper shell 42 and the bottom plate 41 are installed, the upper shell 42 is moved downward from above the bottom plate 41, since the longitudinal section of the latch 412 is triangular, the side wall of the upper shell 42 contacts with the latch 412 to drive the resilient piece 411 to bend so as to make the upper shell 42 move downward stably, and the resilient piece 411 drives the latch 412 to slide along the outer side wall of the upper shell 42, when the latch 412 corresponds to the position of the insertion hole 421, the latch 412 is matched with the insertion hole 421 of the upper shell 42 under the resilient action of the resilient piece 411, so that the upper shell 42 and the bottom plate 41 are butted with each other.

As shown in fig. 3, a circular access hole 422 is formed at one side of the upper casing 42, and a hand of a worker can enter the inside of the casing 4 through the access hole 422, and the hand and the static electricity conductive body 3 are in contact with each other, so that static electricity on a body is conducted and released through the static electricity conductive body 3. The arrangement of the shell 4 plays a role in covering and protecting the static conductive body 3, thereby reducing the influence of floating dust in the air on the static conductive body 3 on the conduction work of the static conductive body 3. Moreover, the inlet and outlet holes 422 are formed on the side wall of the upper shell 42, so that floating dust in the air is not easy to enter the shell 4.

As shown in fig. 3, in order to improve the dust-blocking effect of the housing 4, a plurality of flexible dust-blocking members 43 (8 dust-blocking members 43 are provided in this embodiment) are provided at the edge of the access hole 422 of the upper housing 42, the dust-blocking members 43 are fan-shaped, and the arc surfaces of the dust-blocking members 43 are fixedly connected with the edge of the access hole 422 and uniformly distributed along the edge of the access hole 422, so that the access hole 422 is blocked by the dust-blocking members 43. When the hands of the worker enter the shell 4, the dust blocking piece 43 is made of flexible material, and the penetration of the hands is not affected; when the static conductive body 3 is not touched, the dust blocking member 43 blocks the inlet and outlet 422, so that the floating dust in the air is not easy to enter and exit the housing 4.

As shown in fig. 3 and 4, a cleaning device 5 for cleaning the static electricity conductive body 3 is further disposed in the housing 4, a circular cleaning hole 44 is formed in the upper surface of the upper housing 42, and the cleaning device 5 includes a cover plate 51 disposed above the upper housing 42 and covering the cleaning hole 44; a sliding rod 52 vertically penetrating the cover plate 51 and connected with the cover plate 51 in a sliding manner; three elastic pieces 53 fixedly connected to the lower end surface of the slide bar 52; and a wiping cotton 54 fixed on the side wall of the elastic sheet 53 facing the static conductive body 3. The cover plate 51 is fixed to the upper case 42 by bolts. The elastic pieces 53 are uniformly distributed below the sliding rod 52 by taking the central point of the lower end surface of the sliding rod 52 as a circle center, and the middle parts of the elastic pieces 53 are sunken towards the direction far away from the static conductive body 3.

As shown in fig. 5, when dirt remains on the surface of the electrostatic conductor 3, the worker can slide the sliding rod 52 downward, so that the elastic piece 53 is wrapped on the upper spherical surface of the electrostatic conductor 3 through elastic deformation, and the wiping cotton 54 is in contact with the surface of the electrostatic conductor 3, and the worker can rotate the sliding rod 52 to wipe the surface of the electrostatic conductor 3 with the wiping cloth, thereby cleaning the surface of the electrostatic conductor 3.

Since the electrostatic conductor 3 is spherical, when the hand and the electrostatic conductor 3 are in contact with each other, the main contact area is distributed on the upper spherical surface of the electrostatic conductor 3, and therefore, when the wiping cotton 54 wipes the electrostatic conductor 3, only the upper spherical surface of the electrostatic conductor 3 is wiped.

As shown in fig. 3 and 5, the slide rod 52 is further provided with an elastic member 6 for moving the cleaning device 5 away from the conductive body 3. The elastic component 6 comprises a stop ring 61 fixedly connected with the sliding rod 52 and a spring 62 sleeved on the sliding rod 52. The retainer ring 61 is disposed above the upper case 42, and the spring 62 is disposed between the retainer ring 61 and the upper wall of the upper case 42. The upper end of the sliding rod 52 is fixedly connected with a spherical handle 55, a worker can press the handle 55 to drive the sliding rod 52 and the cover plate 51 to slide, so that the elastic sheet 53 is wrapped on the upper spherical surface of the static electricity conductive body 3, the wiping cotton 54 wipes the surface of the static electricity conductive body 3, and then the handle 55 is rotated, thereby improving the wiping efficiency of the wiping cotton 54 on the static electricity conductive body 3. When the handle 55 is released by the hand of the worker, the slide rod 52 moves up the slide rod 52 under the elastic force of the spring 62, so that the elastic piece 53 is separated from the static electricity conductive body 3, and the elastic piece 53 is clamped below the cover plate 51, thereby leaving a space for the mutual contact between the hand and the static electricity conductive body 3. The casing 4 is transparent plastic material to be convenient for the staff to look over the clean situation on leading static body 3 surface, thereby carry out cleaning work to leading static body 3 through cleaning device 5.

As shown in fig. 4, in order to reduce the abrasion of the elastic piece 53 to the surface of the static electricity conductive body 3, a ball 56 is spherically hinged at the end of the elastic piece 53 away from the sliding rod 52, so that the original sliding friction is replaced by rolling friction between the elastic piece 53 and the surface of the static electricity conductive body 3, thereby reducing the friction between the elastic piece 53 and the static electricity conductive body 3 and reducing the abrasion to the surface of the static electricity conductive body 3. A rubber scraping strip 57 is fixedly connected to the side wall of each elastic sheet 53 facing the static conductive body 3 along the length direction of the elastic sheet 53, and the contact pressure of the scraping strip 57 and the surface of the static conductive body 3 is greater than the pressure of the wiping cotton 54 on the surface of the static conductive body 3, so that dirt on the surface of the static conductive body 3 is easier to wipe off, and the cleaning efficiency of the surface of the static conductive body 3 is improved.

If the wiping cotton 54 is used for a long time, a large amount of stains remain on the surface of the wiping cotton 54, and the cleaning effect of the wiping cotton 54 on the surface of the electrostatic conductive member 3 is reduced. The worker can screw down the bolts that fix the cover plate 51, thereby disengaging the cleaning device 5 from the housing 4, and facilitating the exchange of the wiping cloths 54.

The working process is as follows: if the surface of the static electricity conductive body 3 is in contact with the hand and remains dirt, the worker can press the holding handle 55 down to make the elastic sheet 53 generate elastic deformation, and make the wiping cotton 54 and the spherical surface on the static electricity conductive body 3 contact with each other, then rotate the holding handle 55 to make the wiping cotton 54 and the scraping strip 57 wipe the spherical surface of the static electricity conductive body 3, and the holding handle 55 is loosened after wiping, so that the sliding rod 52 slides upwards under the action of the spring 62, and the elastic sheet 53 is separated from the static electricity conductive body 3, so that the hand can be in contact with the static electricity conductive body 3 through the access hole 422 of the shell 4.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
