Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.
Example (b): as shown in fig. 1-5, the invention provides a technical scheme, and a detachable composite jacket metal oxide lightning arrester comprises a composite jacket 1, wherein a resistance module 2 is wrapped inside the composite jacket 1, terminal seats 3 are respectively arranged at the top end and the bottom end of the resistance module 2, external connecting threads 4 are respectively arranged on the outer side surfaces of the top and the bottom of the composite jacket 1, end covers 5 are respectively arranged at the top end and the bottom end of the composite jacket 1, connecting terminals 21 are respectively arranged in the middle of the two end covers 5 in a penetrating manner, internal connecting threads 6 are respectively arranged on the inner side surfaces of the end covers 5, and the composite jacket 1 and the end covers 5 are detachably connected through the engagement of the internal connecting threads 6 and the teeth of the external.
The outside surface in 5 bottoms of end cover that lie in 1 top of compound overcoat and the outside surface in 5 tops of end cover that lie in 1 bottom of compound overcoat have all seted up first gomphosis groove 7, the inside equidistance of first gomphosis groove 7 is glued there is water conservancy diversion piece 8, second gomphosis groove 9 has all been seted up to 1 top of compound overcoat and the corresponding first gomphosis groove 7 position department of bottom outside surface, first gomphosis groove 7 and the 9 outside surfaces of second gomphosis groove have all wrapped up sealing washer 10, the inboard surface and the first gomphosis groove 7 of sealing washer 10 and the laminating of the 9 surfaces of second gomphosis groove, make sealing washer 10 can effectively seal up first gomphosis groove 7 and second gomphosis groove 9, it enters into inside compound overcoat 1 to reduce external steam, the corresponding water conservancy diversion piece 8 positions department of the inboard surface of sealing.
The top end of the end cover 5 is welded with the positioning mounting post 16 at equal angles, the top end of the end cover 5 is provided with a hook-shaped rod 17 corresponding to the position of the positioning mounting post 16, the top end of the hook-shaped rod 17 is provided with a mounting hole 18 corresponding to the position of the positioning mounting post 16, the bottom end of the hook-shaped rod 17 is spliced with an auxiliary rod 19, the side surface of the auxiliary rod 19 is attached to the outer side surface of the sealing ring 10, the sealing ring 10 is protected by the auxiliary rod 19, the stability of the sealing ring 10 after installation is guaranteed, and the damage of the sealing ring 10 is.
The top of the end cover 5 is provided with a receiving chamber 22, the front end of the receiving chamber 22 is provided with a notch 12, and the articles in the receiving chamber 22 are drawn out through the notch 12.
The working principle and the using process of the invention are as follows: when the detachable composite coat metal oxide lightning arrester is installed, firstly, the sealing ring 10 is placed in the second embedding groove 9, then the hook-shaped rod 17 is rotated, the end cover 5 is driven to rotate through the hook-shaped rod 17, the problem that the outer surface of the end cover 5 is too smooth and is inconvenient to rotate is avoided, because the end cover 5 is meshed and connected with the composite coat 1 through the outer connecting thread 4 and the inner connecting thread 6, after the end cover 5 rotates, teeth move mutually, the end cover 5 is installed at the end part of the composite coat 1, in the installation process of the end cover 5, the first embedding groove 7 at the end part of the end cover 5 slowly moves towards the second embedding groove 9, the sealing ring 10 is sleeved outside the first embedding groove 7, the sealing ring 10 can be effectively attached to the side surfaces of the first embedding groove 7 and the second embedding groove 9, and the external water vapor is prevented from entering the composite coat 1 through the connecting gap between the end cover 5 and the, the damage of the internal resistance module 2 caused by the damage is avoided, meanwhile, the flow guide block 8 is arranged in the first embedding groove 7, when a small amount of water stain enters between the composite outer sleeve 1 and the first embedding groove 7, the water stain can also drop downwards through the flow guide block 8, water liquid entering between the external connecting thread 4 and the internal connecting thread 6 is further reduced, the sealing efficiency of the detachable outer sleeve is improved, the hook-shaped rod 17 is arranged to effectively avoid the situation that the surface of the end cover 5 is too smooth and is difficult to rotate, and the end cover 5 can be taken down only by reversely rotating the hook-shaped rod 17 during the disassembly;
when a user carries the lightning arrester and needs to place the lightning arrester on a plane such as the ground, the mounting hole 18 and the positioning mounting post 16 are separated firstly, the hook-shaped rod 17 is taken down, then the skirt edge of the composite outer sleeve 1 is clamped by utilizing the hook-shaped part of the hook-shaped rod 17, the hook-shaped rod 17 is fixed by the extrusion contact of the rubber cushion block 20 and the skirt edge of the composite outer sleeve 1, the matching of the hook-shaped rods 17 ensures that the skirt edge of the composite outer sleeve 1 can not be in direct contact with the ground when the lightning arrester is placed on the ground, the scratch damage to the surface of the composite outer sleeve 1 caused by the scratch is reduced, when the lightning arrester is installed at high altitude, the positioning mounting post 16 is inserted into the mounting hole 18 again to fix the hook-shaped rod 17, then the limiting rod 15 is pulled to drive the iron wire rope 14 to bypass the rod body, the circular end surface of the limiting rod 15 penetrates through the hook-shaped part of the hook-shaped rod 17, then the limiting rod, make the gag lever post 15 block and collude type pole 17, iron wire rope 14 through 15 mid-mounting of gag lever post can have and place the arrester and hang on the body of rod and put, improve constructor high altitude construction's efficiency, when need not hanging and put, as long as swing gag lever post 15, reuse 15's circular terminal surface passes colludes type pole 17 and colludes type part, produce deformation when 15 pulling of gag lever post because of volute spiral spring 13, volute spiral spring 13 deformation stress withdraws iron wire rope 14 from notch 12 and receives in the cavity 22, avoid iron wire rope 14 to stretch out the normal work that disturbs the arrester.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
