[0019] Example 1 This embodiment provides a 6kV high-voltage cable cold repair intermediate joint mold, including a mold mechanism 100, a fixing mechanism 200 and a glue-filling mechanism 300.

[0020] Reference Figure 1 The mold mechanism 100 includes a pipe body 101, which is made of PVC pipe. The pipe body 101 can be replaced with pipes of different diameters according to the actual use scenario. A first silicone sleeve 102 is sleeved on one side of the pipe body 101, and a second silicone sleeve 103 is sleeved on the other side. The first silicone sleeve and the second silicone sleeve 103 prevent the cable from being damaged by friction at the edge of the pipe body 101 when it enters the pipe body.

[0021] Reference Figure 1 , 2 3. Fixing mechanism 200 includes a rubber band 201 that is wrapped around the outer wall of the pipe body 101. The surface of the rubber band 201 has several holes and grooves to facilitate strengthening the tensile strength. At the same time, there are several sets of rubber bands 201, which can be increased or decreased according to the actual situation. A sleeve 202 is embedded in the upper end of the rubber band 201. The upper end of the sleeve 202 is provided with a vertical first threaded groove 202b.

[0022] Reference Figure 2 , 4 5, 6, The glue dispensing mechanism 300 includes a feeding cylinder 303, the inner wall of which is an oleophobic layer to prevent glue from sticking, and a second threaded tube 304a which is threaded to the first threaded groove 202b at the lower end of the feeding cylinder 303. The second threaded tube 304a can be locked or loosened in the first threaded groove 202b for easy inspection. A glue dispensing funnel 301 is provided at the upper end of the feeding cylinder 303. The glue dispensing funnel 301 is wider at the top and narrower at the bottom.

[0023] Reference Figure 1 , 7 The locking mechanism 400 includes a connecting buckle 401 that passes through the outer wall of the pipe body 101 and a fixing collar 402 that is fixedly connected to the upper end of the connecting buckle 401.

[0024] Reference Figure 1 The first silicone sleeve 102 is cylindrical, and its inner wall diameter is the same as the outer wall diameter of the pipe body 101. The first silicone sleeve 102 penetrates one edge of the outer wall of the pipe body 101 and fits against it. The second silicone sleeve 103 is cylindrical, and its inner wall diameter is the same as the outer wall diameter of the pipe body 101. The second silicone sleeve 103 penetrates the other edge of the outer wall of the pipe body 101 and fits against it.

[0025] Example 2 This embodiment is based on the previous embodiment, but differs from the previous embodiment in that: in this embodiment, the glue-drinking mechanism 300 can be fixed before the glue-drinking operation is performed, after the cable enters the pipe body 101. The specific structure of this embodiment is as follows.

[0026] Combination Figure 3 The adhesive strap 201 is made of a tough and stretchable adhesive material. The sleeve 202 passes through the adhesive strap 201 and fits against the bottom of the adhesive strap 201. This makes it easy for the sleeve to be aligned with the hole on the tube body 101. A sealing ring 202a is provided at one end of the sleeve 202 near the first threaded groove 202b. The diameter of the sealing ring 202a is larger than that of the first threaded groove 202b and fits against the first threaded groove 202b. A round hole is provided on the outer wall of the tube body 101. One end of the sleeve 202 corresponding to the round hole fits against the tube body 101, and the diameter of the sleeve 202 is the same as the diameter of the round hole.

[0027] In this embodiment, before performing cold repair, the adhesive strap 201 is first put on the pipe body 101, the sleeve 202 is aligned with the hole above the pipe body 101, and then the inside of the sleeve 202 is tightened through the second threaded tube 304a. The sealing ring 202a is used to prevent the adhesive from overflowing from the gap, thus completing the fixation before the cold repair operation.

[0028] Example 3 This embodiment is based on the previous embodiment, but differs from the previous embodiment in that: in this embodiment, the glue dispensing mechanism 300 is installed and the glue dispensing operation is performed, and the locking mechanism 400 can be adjusted according to the size of the pipe.

[0029] Reference Figure 5 The lower end of the feeding cylinder 303 is provided with a cylinder tube 304, the inner wall of the cylinder tube 304 is provided with a second threaded tube 304a, and a first threaded tube 303f is fixed to the lower end of the feeding cylinder 303 and threadedly connected to the second threaded tube 304a on the inner wall of the cylinder tube, and the middle of the threaded tube is hollow; a parallel filter screen 304c is attached to the end of the inner wall of the cylinder tube 304 away from the second threaded groove 304b, and the connection between the filter screen 304c and the cylinder tube 304 is sealed with a sealing ring.

[0030] Reference Figure 5 The lower end of the cylinder 304 is fixed with a second threaded tube 304a. The upper end of the second threaded tube 304a is connected to the cylinder 304, and the lower end is connected to the sleeve 202. The second threaded tube 304a is hollow.

[0031] Reference Figure 4 and Figure 5The feeding cylinder 303 is equipped with a rotating circular plate 303c. The rotating circular plate has damping properties in the feeding cylinder to prevent slippage. The rotating circular plate is coated with a layer of adhesive to prevent glue from sticking. A rotating column 303b is provided on one side of the rotating circular plate 303c, and the rotating column 303b penetrates one side of the feeding cylinder 303.

[0032] Reference Figure 5 The upper end of the rotating column 303b is fixed with a limiting tube 303d, and the upper end of the feeding cylinder 303 is provided with a limiting hole 303e. The limiting tube 303d is embedded in the limiting hole 303e. The end of the rotating column 303b is fixedly connected with a torsion plate 303a, and the torsion plate 303a is a trapezoidal shape that is easy to hold.

[0033] Reference Figure 4 , 5 6. The limiting hole 303e is concave, and the limiting tube 303d can rotate 180° within the limiting hole 303e. The length of the rotating column 303b is half the diameter of the rotating circular plate 303c. The rotating column 303b can rotate around one side of the feeding cylinder 303. In order to better fix the glue funnel 301, a connecting screw cylinder 302 is sleeved on the outer wall of the feeding cylinder 303, and the glue funnel 301 is fixed on the upper end of the connecting screw cylinder 302. The connecting screw cylinder 302 is a hollow cylinder. The inner wall of the glue funnel 301 is provided with a scale line 301a, and the end of the scale line 301a extends to the bottom of the glue funnel 301.

[0034] Referring to 7, the upper end of the fixed collar 402 has a threaded groove of the same size as the threaded post 404. The upper end of the fixed collar 402 is threadedly connected to the threaded post 404. The end of the threaded post 404 away from the fixed collar 402 passes through and connects to the lower end of the buckle 401. The upper end of the threaded post 404 is connected to the lever ring 403.

[0035] Reference Figure 1 , 7 A connecting sleeve 405 is sleeved on the lower end of the threaded column 404. The connecting sleeve 405 can be rotated 360° to lock the lower end of the threaded column 404. A rotating disc 406 is fixedly connected to the lower end of the connecting sleeve 405. An arc-shaped support block 407 is fixedly installed on the outer wall of the rotating disc 406. There are two sets of arc-shaped support blocks 407, which are opposite to each other with the inner wall of the pipe body 101 as the boundary.

[0036] In this embodiment, during the potting operation, the cable is first inserted through the hollow end of the pipe body 101 and extends out from the other end. When the diameter of the cable is smaller than the internal diameter of the pipe body 101, the two sets of actuating rings 403 on opposite sides of the pipe body 101 are twisted. The two sets of actuating rings 403 drive their respective threaded posts 404 to rotate, causing the threaded posts 404 to screw into the inner wall of the pipe body 101 under the inward threads of the connecting ring 401 and the fixing ring 402. This also causes their respective arc-shaped support blocks 407 to move along with the threaded posts 404, preventing the arc-shaped support blocks 407 from moving with the threaded posts 404 during rotation. The threaded posts 404 and the arc-shaped support blocks 407 are connected by a rotating disc 406. This method prevents the arc-shaped support block 407 from rotating by rotating the disc 406. The internal cable is supported and fixed by two sets of arc-shaped support blocks 407, which makes it easy to adjust according to cables of different diameters, saving time and effort. Then, the rotating disc 303c is aligned with the upper end of the feeding cylinder 303, and then glue is poured in. The amount of glue poured in can be accurately observed through the scale line 301a. When a certain amount is reached, the torsion plate 303a is rotated, which drives the rotating column 303b to rotate, so that the rotating disc 303c at the other end of the rotating column 303b is misaligned with the feeding cylinder 303. This allows the glue to flow from the feeding cylinder 303 into the cable inside the pipe body 101 for cold patching.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
