[0003] The above-mentioned method for detecting the sealing of the cable is to spray water on the outer surface of the cable, and then check whether bubbles are generated on the outer surface of the cable after the water is sprayed, so as to judge the sealing of the cable;

[0004] This method of detecting the sealing of cables is not accurate enough, because the nozzle sprays water on the outer surface of the cable, and it is impossible to generate bubbles without gas squeezing input inside the cable. Therefore, this detection method has a principle problem. Therefore, it is necessary to provide a cable sealing detection device to solve the above technical problems. Utility Model Content

[0005] The purpose of the utility model is to provide a device for detecting the sealing performance of cables, so as to solve the problem that the method for detecting the sealing performance of cables in the comparative documents proposed in the above-mentioned background technology is not accurate enough. The technical solution of the utility model is aimed at the technical problem that the solutions of the prior art are too single, and provides a solution that is significantly different from the prior art.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for detecting the sealing of a cable, comprising a detection box, wherein oil cylinders are installed on the upper and lower parts of the detection box through support rods, and a cylinder is arranged on one side of the oil cylinder; further comprising a limit mechanism, wherein the limit mechanism is installed on the inner side of the oil cylinder; a connecting cylinder, wherein the connecting cylinder is installed on the inner side of the detection box through a rod; a water cylinder, wherein the water cylinder is arranged above the detection box; and an adjustment mechanism, wherein the adjustment mechanism is located above the detection box.

[0010] In a further embodiment, a scale is provided on the outside of the water cylinder.

[0011] In a further embodiment, the adjustment mechanism includes a limit rod installed on the inner side of the water cylinder, and a spring is clamped on the outer side of the limit rod. The outer side of the limit rod is connected to an extrusion plate, and a weight is placed above the extrusion plate.

[0012] In a further embodiment, the other end of the connecting pipe is connected to the bottom of the water cylinder.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model is provided with a limit mechanism, which can effectively drive the piston by starting the cylinder, and squeeze the oil inside the sleeve into the inside of the oil cylinder, so that the oil inside the oil cylinder is evenly squeezed into the inside of each telescopic rod. Compared with the existing detection equipment, the telescopic rod drives the ball to extend and contact the outer surface of the cable, thereby effectively straightening and clamping the detection cable, thereby improving the detection efficiency of the cable sealing;

[0015] 2. The utility model is provided with an adjustment mechanism, which drives the cable reel to rotate through a driving element, so that the cable is slowly wound and reeled. By adding a weight to the outside of the limit rod, the weight can effectively squeeze the extrusion plate and the water in cooperation with the spring, and then the water inside the water cylinder is squeezed into the inside of the connecting cylinder in cooperation with the connecting pipe. Compared with the existing testing equipment, it can effectively adjust the cables of different materials and different diameters during the sealing test;

[0016] 3. The utility model can replace sealing rings of different diameters according to the cables of different diameters when testing cables of different diameters. When the cable inside the connecting tube has a sealing problem, it means that the cable in this section has cracks or holes. At this time, water squeezed from the inside of the water cylinder into the connecting tube will also be squeezed into the holes or cracks in the cable. At this time, just check the scale and observe that the water level is obviously dropping, which proves that there is a problem with the sealing of the cable. If there is no problem with the sealing of the cable in this section of the connecting tube, the water level inside the water cylinder will not change significantly. Compared with the existing testing equipment, the above structure does not need to use multiple power units, and overcomes the problems raised by the background technology. Therefore, the equipment is more suitable for the market. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 The utility model provides an embodiment: a device for detecting the sealing of a cable, comprising a detection box 1, wherein the detection box 1 is provided with oil cylinders 2 on the upper and lower sides through support rods, and a cylinder 3 is provided on one side of the oil cylinder 2; further comprising a limiting mechanism 4, wherein the limiting mechanism 4 is installed on the inner side of the oil cylinder 2; a connecting cylinder 5, wherein the connecting cylinder 5 is installed on the inner side of the detection box 1 through a rod; a water cylinder 6, wherein the water cylinder 6 is arranged above the detection box 1; and an adjusting mechanism 7, wherein the adjusting mechanism 7 is located above the detection box 1. Example 1

[0024] See also Figure 1 and Figure 3 , one side of the oil cylinder 2 is connected with a sleeve 201, and the sleeve 201 is arranged corresponding to the cylinder 3, the limiting mechanism 4 includes a telescopic rod 401 installed on the inner side of the oil cylinder 2, and the end of the telescopic rod 401 is connected to a limiting block 402, and the inner side of the limiting block 402 is movably connected with a ball 403;

[0025] First, insert the cable to be tested into the inner side of the test box 1 from the upper limiting mechanism 4, and pass through the connecting tube 5 and the lower limiting mechanism 4, then start the cylinders 3 on the upper and lower sides of the test box 1 through the control button, and drive the piston through the cylinder 3 to squeeze the oil inside the sleeve 201 into the inner side of the oil cylinder 2, so that the oil inside the oil cylinder 2 is evenly squeezed into the inner side of each telescopic rod 401, so that the telescopic rod 401 drives the ball 403 to extend and contact the outer surface of the cable, thereby effectively straightening and clamping the test cable. Example 2

[0026] See also Figure 1-2 and Figure 4 , which is different from Example 1 in that: both upper and lower sides of the connecting tube 5 are provided with connecting heads 501, and a sealing ring 502 is installed inside the connecting head 501, a connecting pipe 503 is connected to the top of the connecting tube 5, and the other end of the connecting pipe 503 is connected to the bottom of the water cylinder 6, and a scale 601 is arranged on the outside of the water cylinder 6, and the adjustment mechanism 7 includes a limiting rod 701 installed on the inside of the water cylinder 6, and a spring 703 is clamped on the outside of the limiting rod 701, and an extrusion plate 704 is connected to the outside of the limiting rod 701, and a weight 702 is placed above the extrusion plate 704;

[0027] After the cable is straightened and clamped, the cable reel is driven to rotate by the driving element, so that the cable is slowly wound and reeled. At the same time, a weight 702 is added to the outside of the limit rod 701, so that the weight 702 squeezes the squeezing plate 704 and the water in cooperation with the spring 703, so that the water inside the water cylinder 6 is squeezed into the inside of the connecting tube 5 in cooperation with the connecting pipe 503. Since the connecting tube 5 is equipped with sealing rings 502 through the connecting head 501 at the top and bottom, and the sealing ring 502 is made of Teflon, its sealing performance is much better than that of the ordinary sealing ring 502, and its wear resistance is also very excellent;

[0028] When testing cables of different diameters, sealing rings 502 of different diameters can be replaced according to the cables of different diameters. When the cable inside the connecting tube 5 has a sealing problem, it means that the cable in this section has cracks or holes. At this time, the water squeezed into the connecting tube 5 from the inside of the water tube 6 will also be squeezed into the holes or cracks of the cable. At this time, just check the scale 601 and observe that the water level is obviously dropping, which proves that there is a problem with the sealing of the cable. If there is no problem with the sealing of the cable in this section of the connecting tube 5, the water level inside the water tube 6 will not change significantly.

[0029] Working principle: Figure 1 and Figure 3As shown, the cable to be tested is first inserted into the inner side of the test box 1 from the upper limiting mechanism 4, and passes through the connecting tube 5 and the lower limiting mechanism 4, and then the cylinders 3 on the upper and lower sides of the test box 1 are started by the control button, and the piston is driven by the cylinder 3 to squeeze the oil inside the sleeve 201 into the inner side of the oil cylinder 2, so that the oil inside the oil cylinder 2 is evenly squeezed into the inner side of each telescopic rod 401, so that the telescopic rod 401 drives the ball 403 to extend and contact the outer surface of the cable, so that the detection cable can be effectively straightened and clamped;

[0030] like Figure 1-2 and Figure 4 As shown, after the cable is straightened and clamped, the cable reel is driven to rotate by the driving element, so that the cable is slowly wound and reeled. At the same time, a weight 702 is added to the outside of the limit rod 701, so that the weight 702 squeezes the squeezing plate 704 and the water in cooperation with the spring 703, so that the water inside the water cylinder 6 is squeezed into the inside of the connecting tube 5 in cooperation with the connecting pipe 503. Since the connecting tube 5 is equipped with sealing rings 502 through the connecting head 501 at the top and bottom, and the sealing ring 502 is made of Teflon, its sealing performance is much better than that of the ordinary sealing ring 502, and its wear resistance is also very excellent;

[0031] When testing cables of different diameters, sealing rings 502 of different diameters can be replaced according to the cables of different diameters. When the cable inside the connecting tube 5 has a sealing problem, it means that the cable in this section has cracks or holes. At this time, the water squeezed from the inside of the water cylinder 6 into the connecting tube 5 will also be squeezed into the holes or cracks of the cable. At this time, just check the scale 601 and observe that the water level is obviously dropping, which proves that there is a problem with the sealing of the cable. If there is no problem with the sealing of the cable in this section of the connecting tube 5, the water level inside the water cylinder 6 will not change significantly. Therefore, the sealing of the cable can be effectively and efficiently tested.
