Description

Technical Field

[0001] The utility model relates to the field of cable sealing, in particular to a cable sealing device with a protection function. Background Technique

[0002] A cable sealing device is a device used to seal a cable protection pipe. The sealing of the cable protection pipe is very important. If the cable protection pipe is not sealed tightly, it is easy to cause water accumulation in the cable channel. The cable is tightly pressed by water for a long time, and small animals enter the cable channel, resulting in leakage and power failure, seriously affecting the safe operation of the line.

[0003] A Chinese patent with the patent publication number CN110416960B and the patent name of an underground cable pipeline plugging device discloses a device for plugging a cable pipeline. It can complete the plugging of the cable protection pipe through the provided sealing cylinder, outer sealing sleeve, sealing gasket ring, sealing pressure ring and inner sealing sleeve. Among them, both the outer sealing sleeve and the inner sealing sleeve are made of silica gel, and both will deform under pressure. The deformed outer sealing sleeve will block the space between the protection pipe and the plugging device, and the deformed inner sealing sleeve will hold the cable inserted into the plugging device tightly, thus completing the plugging of the cable pipeline. However, each component of the above device is composed of two parts. If the cable protection pipe is immersed in water for a long time, liquid may penetrate into the interior of the plugging device from the joints of each component. Moreover, the above plugging device is only fixed in the cable protection pipe through the deformed outer sealing sleeve and inner sealing sleeve. If the liquid has a relatively persistent impact force, the plugging device may become loose due to the impact force. To solve the above problems, a cable sealing device with a protection function is proposed. Content of the Utility Model

The driving handle 2225 is slidably connected with the air expelling groove 2226. An air expelling strip 2228 is arranged on the driving handle 2225. The driving handle 2225 is used to drive the air expelling strip 2228 to rotate circumferentially along the air expelling groove 2226 to increase the air pressure inside the hollow area 2227. An air inlet pipe 2223 is further arranged on the gas supply disc 2222. The air inlet pipe 2223 is used to communicate the airbag ring 2221 and the hollow area 2227.

[0029] In this embodiment, the plugging assembly 1 and the screwing-in cover 21 both belong to the prior art. It includes a sealing cylinder 6, an outer sealing sleeve 5, a sealing gasket ring 4, a sealing pressing ring 3 and an inner sealing sleeve 7. Among them, the outer sealing sleeve 5, the sealing gasket ring 4 and the sealing pressing ring 3 are all sleeved on the outer wall of the sealing cylinder 6. The inner sealing sleeve 7 is located inside the sealing cylinder 6. By squeezing the outer sealing sleeve 5, it can be deformed outward to contact the inner wall of the cable pipeline until they fit. Then, by squeezing the inner sealing sleeve 7, it makes the inner sealing sleeve 7 deform inward. The deformed inner sealing sleeve 7 contacts the cable until the inner sealing sleeve 7 tightly holds the cable, thus completing the plugging of the cable. Since the above components all belong to the prior art, the connection methods between the components will not be elaborated.

[0030] Furthermore, a threaded groove opposite to the connecting seat 223 is formed on the side wall of the screwing-in cover 21. A thread opposite to the threaded groove is arranged on the connecting seat 223. The connecting seat 223 is threadedly connected with the screwing-in cover 21.

[0031] In this embodiment, the shape of the connecting seat 223 is cylindrical. Correspondingly, the shape of the threaded groove is circular.

[0032] Furthermore, the airbag ring 2221 is sleeved on the mounting seat 221. The airbag ring 2221 includes a mounting ring and an airbag. The airbag is arranged along the outer circumference of the mounting ring.

[0033] In this embodiment, the mounting ring is sleeved on the mounting seat 221. The airbag ring 2221 is screwed to the mounting ring. It should be noted that when the whole device is placed in the inner chamber of the cable pipeline, the uninflated airbag does not contact the inner wall of the pipeline.

[0034] Further, the shape of the air supply disc 2222 is cylindrical, and the shapes of the air driving groove 2226, the hollow area 2227, and the solid area 2224 are all arc-shaped.

[0035] In this embodiment, the cylindrical air supply disc 2222 and the arc-shaped hollow area 2227 can enable the air driving strip 2228 to have a longer moving distance, and when the driving handle 2225 rotates once, more gas can be input into the airbag.

[0036] Further, a sliding groove 22210 is formed on the inner wall of the air driving groove 2226, a sliding plate 2229 opposite to the sliding groove 22210 is arranged on the side wall of the driving handle 2225, the sliding plate 2229 is embedded in the sliding groove 22210, the air driving strip 2228 is installed at the bottom of the driving handle 2225, and the air driving strip 2228 is located in the air driving groove 2226.

[0037] In this embodiment, the number of both the sliding groove 22210 and the sliding plate 2229 is two. The two sliding grooves 22210 are respectively arranged on the two side walls of the air driving groove 2226, and the two sliding plates 2229 are respectively arranged on the two side walls of the driving handle 2225.

[0038] Further, a spring 22211 is also arranged on the driving handle 2225, and one end of the spring 22211 is fixedly connected to the solid area 2224.

[0039] In this embodiment, the shape of the spring 22211 is arc-shaped, the spring 22211 is located in the air driving groove 2226, and is used to reset the driving handle 2225.

[0040] Further, a check valve is arranged on the air inlet pipe 2223, an air outlet pipe is arranged on the airbag ring 2221, and one end of the air inlet pipe 2223 is communicated with the hollow area 2227.

[0041] In this embodiment, the check valve can prevent the gas entering the airbag from returning to the external air, and the air outlet pipe is used to discharge the gas in the airbag.

[0042] The specific operation steps of the cable sealing device with protection function are as follows: After sealing the cable duct through the sealing component 1, turn the driving handle 2225, so that the air expelling strip 2228 rotates along the air expelling groove 2226. When the air expelling strip 2228 enters the hollow area 2227, it will squeeze the gas in the hollow area 2227, so that the gas inside it enters the airbag ring 2221 through the air inlet pipe 2223. After completing one inflation, move the driving handle 2225 back to its original position, and repeat the above steps until the airbag is in close contact with the inner wall of the cable duct. It should be noted that when the driving handle 2225 is not subjected to force, the end of the air expelling strip 2228 is located outside the hollow area 2227, which can make the hollow area 2227 filled with air again for the next inflation.
