DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] Embodiment 1, by Figure 1-4 The utility model relates to an outdoor ultra-high voltage tubular busbar structure, comprising two tubular busbar assemblies 1, wherein the tubular busbar assemblies 1 comprise a tubular busbar body 101, and a connection assembly 2 is installed between the two tubular busbar bodies 101;

[0024] The ends of the two tubular busbar bodies 101 close to each other are both installed with threaded tubes 102 , and a sealing ring 103 is fixedly installed on the outer wall of the end of the tubular busbar body 101 close to the threaded tube 102 , and the side walls of the sealing ring 103 are symmetrically provided with clamping grooves 104 .

[0025] The connection assembly 2 includes a connection sleeve 201 arranged between two tubular busbar bodies 101, and thread grooves 210 are provided on the inner walls at both ends of the connection sleeve 201. The two threaded tubes 102 are respectively threadedly connected to the connection sleeve 201 through the two thread grooves 210. Two protective sleeves 202 are symmetrically sleeved and installed on the outer side of the connection sleeve 201. The inner wall of the protective sleeve 202 contacts the outer wall of the connection sleeve 201. Sliders 203 are installed on the inner top wall and the inner bottom wall of the protective sleeve 202. The slides 203 are slidably installed inside the slide grooves 204. The slide grooves 204 are symmetrically provided on the outer wall of the connection sleeve 201. The slides 203 are away from the tubular busbar body. A first spring 205 is fixedly installed on one side of the body 101, and one end of the first spring 205 is fixedly connected to the inner wall of the end of the slide groove 204 away from the tubular busbar body 101. The two protective sleeves 202 are pulled outward and move to the outside of the sealing rings 103 on the two tubular busbar bodies 101. At this time, the first spring 205 is stretched, and the two sides of the protective sleeve 202 are symmetrically installed on the side tube 206. A movable block is movably installed inside the side tube 206, and a clamping rod 207 is installed on one side of the movable block. The threaded tube 102 at the end of the tubular busbar body 101 is threadedly connected with the connecting sleeve 201 for easy installation. At the same time, the protective sleeve 202 is moved outward After reaching the outside of the sealing ring 103, the clamping rod 207 is clamped into the clamping groove 104 on the outer wall of the sealing ring 103, further improving the connection stability between the tubular busbar body 101 and the connecting sleeve 201. The diameter of the clamping rod 207 is smaller than the diameter of the movable block. The end of the clamping rod 207 penetrates the inner side of the protective sleeve 202. After the two protective sleeves 202 are pulled outward, the clamping rod 207 corresponds to the clamping groove 104 on the sealing ring 103, and the clamping rod 207 is clamped into the inside of the clamping groove 104. The diameter of the clamping rod 207 is the same as the inner diameter of the clamping groove 104. A second spring 208 is fixedly installed on the side of the movable block away from the clamping rod 207. One end of 8 is fixedly connected to the inner wall of one end of the side tube 206 away from the protective sleeve 202, and a pull rod 209 is fixedly installed on the side of the movable block away from the clamping rod 207. The pull rod 209 penetrates to the outside of the side tube 206, and the protective sleeve 202 moves outward to the outside of the sealing ring 103, so that the protective sleeve 202 blocks the outside of the connection position between the tubular busbar body 101 and the connecting sleeve 201, thereby improving the outdoor rainproof performance. At the same time, when the protective sleeve 202 is pulled outward, the first spring 205 is stretched. Under the action of the elastic force of the first spring 205, the tightness between the sealing ring 103 and the end of the connecting sleeve 201 is improved, thereby improving the rainproof performance.

[0026] Working principle: During installation, the threaded tubes 102 at the ends of the two tubular busbar bodies 101 are respectively tightened and installed through the threaded grooves 210 on the inner walls of the two ends of the connecting sleeves 201 to facilitate the connection of the two tubular busbar bodies 101. After installation, the two protective sleeves 202 are moved outward so that the two protective sleeves 202 are respectively moved to the outside of the sealing rings 103 on the two tubular busbar bodies 101. When moving, the pull rod 209 is pulled so that the clamping rod 207 enters the inside of the side tube 206. When the protective sleeve 202 moves to the outside of the sealing ring 103, the pull rod 209 is released. At this time, the clamping rod 207 moves back under the elastic force of the second spring 208, so that the clamping rod 207 is clamped into the clamping groove 104 on the outer wall of the sealing ring 103, thereby further clamping and fixing the tubular busbar body 101 and the connecting sleeve 201, and the protective sleeve 202 moves outward to the outside of the connection position between the tubular busbar body 101 and the connecting sleeve 201, thereby improving the outdoor rainproof performance. At the same time, when the protective sleeve 202 moves outward, the first spring 205 is stretched. Under the elastic force of the first spring 205, the sealing ring 103 is further tightly attached to the side wall of the end of the connecting sleeve 201, thereby improving the rainproof performance.
