[0017] The technical solutions in the embodiments of the utility model are described clearly and completely below in conjunction with the accompanying drawings. It is obvious that the described embodiments represent only a portion of the embodiments of the utility model and not all embodiments. Starting from the embodiments of the present utility model, all other embodiments that a person skilled in the art can produce without creative effort fall within the scope of protection of the present utility model.

[0018] With reference to the Fig. 1-5, the utility model shows a technical solution: a ground wire clamping device comprising a mounting seat 1, a vertical plate 3, and a movable ring 9. Mounting nails 2 are attached to the corners of the mounting seat 1, and a vertical plate 3 is fixed to the central part of the mounting seat 1, which is vertically distributed with the mounting seat 1. The upper end surface of the grooves 4 on the surface of the vertical plate 3 is fixed to the outer end surface of the movable ring 9 to facilitate the rotation of the movable ring 9 within the grooves 4 on the surface of the vertical plate 3. The center of the vertical plate 3 is provided with a groove 4 having a "concave" shape, and the side plates 5 are located at both ends of the groove 4, and the side plates 5 are welded to the movable ring 9, which facilitates the rotation of the movable ring 9 by the side plates 5.

[0019] See Fig.1-5, the central part of the vertical plate 3 is provided with a movable ring 9, and both ends of the movable ring 9 are provided with side plates 5, the surface of the side plates 5 is provided with movable grooves 6, and the surface of the side plates 5 is evenly mounted with a tooth block 7, and the central part of the side plates 5 is connected to the vertical plate 3 by a connecting shaft 8. Inside the movable ring 9 is a squeeze pad 10. The movable ring 9 has an open shape, and the connection between the inside of the movable ring 9 and the squeeze pad 10 is an adhesive connection, and the thickness of the squeeze pad 10 increases from the outside to the inside, so that when the movable ring 9 is rotated, the squeeze pad 10 can be used to limit the position of the baseline.One side of the vertical plate 3 is fixedly installed with a placement pad 11. The lower end of the placement pad 11 is set in a curved shape, and the placement pad 11 and the squeeze pad 10 are made of the same material. The placement pad 11 and the squeeze pad 10 are made of butyl rubber, and the upper end of the placement pad 11 is a flat surface, which is convenient for protecting the floor line to avoid damage to the floor line extrusion. Both sides of the end of the vertical plate 3 are opened with an inner groove 12, and the inner groove 12 of the inner tongue 13. The bottom of the tongue 13 is fixed to the limit block 14. The limit block 14 is set under the teeth. The teeth of the surface of the side plate 5, tooth block 7, and the inner groove of the vertical plate 3 limit block 14 form a snap connection to facilitate the side plate 5 after rotation of the snap positioning.

[0020] Working principle: First, install the bracket 1 of the device through the mounting nail 2 inside the site of the thermal power plant where the grounding wire needs to be installed, and then place the grounding wire on the placement pad 11, and then rotate the side plate 5, so that the side plate 5 drives the movable ring 9 in the center to rotate in the groove 4 in the center of the vertical plate 3. The rotation of the movable ring 9 causes the crush pad 10 inside the movable ring 9 to pass over the right end of the placement pad 11, and the thickness of the crush pad 10 gradually becomes thicker, so that with the rotation of the movable ring 9, the crush pad 10 slowly crushes the ground wire over the placement pad 11 so that the ground wire is clamped.And the tooth block 7 on the surface of the side plate 5 will form a clamping connection with the limiting block 14 in the inner inner groove 12 of the vertical plate 3, which is convenient for clamping and positioning the position of the side plate 5 after its rotation. Conversely, when the ground wire is to be removed, the side plate 5 can be rotated in the reverse direction, so that the opening of the movable ring 9 is arranged on the top side of the laying mat 11 for the work of removing the ground wire from the inside. This is the principle of using the ground wire clamping device, and the content not described in detail in this specification is known to those skilled in the art.

[0021] Although embodiments of the utility model have been shown and described, it will be understood by those skilled in the art that numerous changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the utility model, and the scope of the utility model is limited by the appended claims and their equivalents.
