[0001] The utility model relates to the technical field of pressure equalizing rings, in particular to a detachable pressure equalizing ring. Background Art

[0002] The grading ring is a ring-shaped hardware that improves the voltage distribution of the insulator string. The function of the grading ring is to prevent side lightning strikes. It is suitable for AC voltage and can evenly distribute high voltage around the object to ensure that there is no potential difference between the various parts of the ring, thereby achieving the effect of voltage grading.

[0003] When installing the pressure equalizing ring, a connecting piece is set on its inner side for fixed installation through the connecting piece. Most of the existing connecting pieces are installed with the pressure equalizing ring by welding. This results in that when the pressure equalizing ring is disassembled, the pressure equalizing ring needs to be disassembled together with the connecting piece, which is inconvenient to operate. Moreover, the ring-mounted structure of the pressure equalizing ring requires the entire pressure equalizing ring to be put on the installation position of the connecting piece before installation. After disassembly, the pressure equalizing ring needs to be lifted over the installation position before it can be removed, which aggravates the inconvenience of disassembling the pressure equalizing ring. Utility Model Content

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Reference Figure 1-Figure 5 , a detachable pressure-equalizing ring, comprising a pressure-equalizing ring and a connecting piece arranged on the inner side of the pressure-equalizing ring. During installation, the connecting piece comprises two coaxial corresponding and arc-shaped clamping plates 9, both ends of which are equipped with fixing ears 10. The fixing ears 10 on the two clamping plates 9 are connected by a third fastener 11. In actual use, the third fastener 11 is one of a bolt and a screw. The two clamping plates 9 are respectively placed on both sides of the installation position of the high-voltage wire or high-rise building, so that the clamping plates 9 wrap the installation position, and then the third fastener 11 is taken through the fixing ear 10. As the third fastener 11 is twisted, pressure is applied to the clamping plates 9, so that the clamping plates 9 are relatively clamped in the installation position;

[0026] It should be noted that if Figure 4 As shown, a number of anti-slip strips 19 are installed on the inner wall of the splint 9 at intervals. The anti-slip strips 19 are elastic rubber strips. When the splint 9 is fastened to the installation position, the rubber structure of the anti-slip strips 19 will increase the friction between the splint 9 and the installation position to reduce the possibility of accidental sliding of the splint 9. In addition, the rubber strips are elastic. As the two splints 9 are connected, they will also provide the splint 9 with an elastic force in the opposite direction of its movement during installation, so that the third fastener 11 can be tensioned, thereby further strengthening the fastening effect of the splint 9 in the installation position.

[0027] like Figure 1 and Figure 4As shown, at least one second U-shaped seat 12 with an opening upward is installed on the outer side of the splint 9, and a connecting rod 13 is provided in the second U-shaped seat 12. A second through hole 15 is provided on the other end of the connecting rod 13, wherein connecting shafts 14 are installed on both sides of one end of the connecting rod 13 close to the splint 9, and the other end of the connecting shaft 14 is rotatably connected to the inner wall of the second U-shaped seat 12, so that the connecting rod 13 is rotatably installed in the second U-shaped seat 12, so that the connecting rod 13 can be deflected upward in the second U-shaped seat 12 to store the connecting rod 13 for easy carrying and transportation.

[0028] Furthermore, the bottom of one end of the connecting rod 13 close to the splint 9 is matched with the bottom clearance of the second U-shaped seat 12. When the connecting rod 13 is lowered and arranged along the radial direction of the splint 9, the bottom of the connecting rod 13 will be seated on the bottom of the second U-shaped seat 12, so that the second U-shaped seat 12 can provide upward support for the connecting rod 13; that is, after the connecting piece is fixed, the connecting rod 13 will be stretched outward to form a bracket that can provide support.

[0029] Then take the pressure equalizing ring, such as Figure 1 and Figure 3 As shown, the pressure-equalizing ring is an annular tube body 1, and a slot 2 is opened on the tube body 1 to make the tube body 1 into an arc shape. An arc-shaped connecting pipe 3 is coaxially arranged in one end of the tube body 1, and the other end of the connecting pipe 3 corresponds to the other end of the tube body 1 and the two are connected by a first fastener 4. In actual use, the first fastener 4 is a bolt or a screw. The first fastener 4 is loosened and the connecting pipe 3 is pushed back to the end of the tube body 1 away from the first fastener 4, so that the slot 2 is completely open. In this way, the tube body 1 can be directly pushed horizontally onto the connecting piece, and then the connecting pipe 3 is moved back to its original position and fixed with the first fastener 4.

[0030] In order to prevent the connecting tube 3 from being accidentally completely retracted into the tube body 1, thereby affecting the subsequent formation of a complete annular structure of the tube body 1, a limit seat 18 is installed on the outer wall of the connecting tube 3 close to the first fastener 4. The limit seat 18 corresponds to the end of the tube body 1, and limits the extension and contraction of the connecting tube 3 in the end of the tube body 1 away from the first fastener 4, preventing the connecting tube 3 from being unable to move back to its original position; in actual use, the length of the connecting tube 3 is greater than the length of the slot 2.

[0031] At least one group of relatively arranged and arc-shaped sleeves 5 are sleeved on the tube body 1, and the sleeves 5 are coaxially corresponding to the tube body 1, and the sleeves 5 are fixed to the tube body 1 by a second fastener 6. In actual use, the second fastener 6 is a bolt or a screw, which is convenient for disassembly of the sleeve 5 on the tube body 1; a first U-shaped seat 7 with an opening downward is installed on the inner side of the sleeve 5, and the side of the first U-shaped seat 7 is fixed on the sleeve 5. The first U-shaped seat 7 corresponds to the second U-shaped seat 12 one by one. After the tube body 1 is pushed horizontally above the connecting piece, the tube body 1 can be directly placed on the connecting piece, that is, the first U-shaped seat 7 falls on the end of the connecting rod 13 away from the second U-shaped seat 12, and first through holes 8 are symmetrically opened on both sides of the first U-shaped seat 7. The first through hole 8 corresponds to the second through hole 15, so that the connecting rod 13 is installed in the first U-shaped seat 7 through a fixing piece;

[0032] Specifically, the fixing member includes a screw 16, which is placed in the second through hole 15, and the end of the screw 16 passes through the first through hole 8 and is threadedly connected with a locking nut 17, and the locking nut 17 corresponds to the outer wall of the first U-shaped seat 7. After the connecting rod 13 is placed in the first U-shaped seat 7, the screw 16 is taken through the through hole, and the locking nuts 17 are taken and screwed on both ends of the screw 16 until the locking nuts 17 are tightly attached to the outer wall of the first U-shaped seat 7, thereby fixing the tube body 1 and the connecting member; and since both ends of the screw 16 are fixed with the locking nuts 17, the screw 16 can be selectively disassembled, which improves the convenience of disassembling and assembling the screw 16 from the through hole, and provides convenience for the disassembly of the tube body 1 on the connecting member.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
