Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a cable connection protection device for electric power engineering. Background Art

[0002] Power engineering mainly involves the production, transmission, and distribution of electric energy, that is, various engineering technologies and projects related to electric energy. During the use of power engineering, cables need to be laid. In order to ensure the connectivity of the cables, the cables usually need to be docked. In order to prevent moisture from entering the wiring of the cables, a junction box is required. The cables in the conduit are connected in the junction box to protect and connect the cables.

[0003] For example, in the prior art, a Chinese patent with a patent publication number of CN218888040U discloses a cable wiring protection device for power engineering. First, a fixing ring is set on the cable connection, and the position of the cable connection is adjusted by turning the first screw until the arc-shaped clamping plate connected by rotation clamps the cable so that it is located at the center of the fixing ring. Then the cable with the fixing ring is placed in the box body, and the cable position is adjusted by turning the second screw. When the cable is located at the center of the box body, a rubber belt is wrapped around the cable at the outlets on both sides of the box body, and then the box cover is fixed to the box body by fixing bolts. At this time, the extrusion block contacts the rubber pad under the action of the spring, so that the rubber pad fits with the inner wall of the box cover, thereby increasing the sealing. At this time, the outlet is blocked by the rubber belt wrapped on the cable, and then the rubber belt is wrapped so that the rubber belt completely wraps the connection between the cable and the outlet, and finally a sealant is applied to seal it.

[0004] The device first clamps and fixes the cable connection with a clamping device, and then places the clamping device into a box body. The connection between the clamping device and the box body is completely through friction. During the cable pulling process, the clamping device and the box body will move laterally, resulting in the clamping device being unable to accurately clamp the cable connection, affecting the stability of the cable connection. Therefore, a power engineering cable connection protection device is designed to solve the above problem. Utility Model Content

[0027] Example:

[0028] like Figure 1-Figure 6 As shown, the embodiment of the utility model provides a power engineering cable connection protection device, including: a sleeve 1, the sleeve 1 is a pipe structure with a large central diameter and small diameters at both ends, an opening groove 101 is opened in the center of the sleeve 1, a receiving groove 102 is opened below the opening groove 101, an arc-shaped baffle 2 is movably arranged inside the receiving groove 102, an embedding groove 103 is opened above the opening groove 101, a fixing bolt 104 is threadedly connected above the embedding groove 103, bolt holes 201 are opened on both sides of the upper left and right sides of the arc-shaped baffle 2, and a clamping component is fixedly arranged at the inner center of the sleeve 1;

[0029] The clamping assembly includes a rectangular frame 3, a guide sleeve 301, a spring 302, a guide column 303, a first arc plate 304, a locking bolt 305 and a second arc plate 306. The guide sleeve 301 is fixedly arranged on the inner bottom of the rectangular frame 3, the spring 302 is fixedly arranged on the inner bottom of the guide sleeve 301, the guide column 303 is fixedly arranged on the top of the spring 302, the first arc plate 304 is fixedly arranged on the top of the guide column 303, the locking bolt 305 is threadedly connected to the center of the upper surface of the rectangular frame 3, and the second arc plate 306 is rotatably arranged on the bottom of the locking bolt 305 through a bearing.

[0030] During actual use, loosen the fixing bolts 104, move the arc baffle 2 downward, so that the arc baffle 2 is in the storage groove 102, and the arc baffle 2 will not block the open groove 101, and then the cables to be connected are respectively passed through the left and right ends of the sleeve 1, and the cables pass through the clamping assembly, and the two cables to be connected are connected through the open groove 101. After the connection is completed, the cable connection is moved to the clamping assembly, and the connection is clamped by the clamping assembly. Since the clamping assembly is fixed in the sleeve 1, the clamping assembly can be prevented from lateral movement in the sleeve, ensuring that the clamping assembly stably clamps the cable connection, and then move the arc baffle 2 upward, embed the arc baffle 2 in the embedding groove 103, and lock the arc baffle 2 by the fixing bolts 104, and the arc baffle 2 blocks the open groove 101. Finally, waterproof glue is applied to the gap between the sleeve 1 and the cable and the gap between the arc baffle 2 and the open groove 101 to achieve a waterproof effect;

[0031] By providing a clamping assembly, when the cable is clamped, the cable connection is between the first arc plate 304 and the second arc plate 306. By turning the locking bolt 305, the locking bolt 305 drives the second arc plate 306 to move downward, and cooperates with the first arc plate 304 to clamp the cable connection. This is suitable for clamping cables of different diameters. When the cable is clamped, the first arc plate 304 moves downward and squeezes the spring 302 through the guide column 303. The elastic force of the spring 302 makes the first arc plate 304 always close to the cable connection, thereby ensuring the stability of the cable connection.

[0032] In this embodiment, the arc baffle 2 is made of rubber, and the depth of the receiving groove 102 is smaller than the length of the arc baffle 2 , so as to prevent the arc baffle 2 from being completely in the receiving groove 102 , thereby facilitating the movement of the arc baffle 2 .

[0033] In this embodiment, the arc baffle 2 matches the embedding groove 103, and when the arc baffle 2 is embedded in the embedding groove 103, the bolt hole 201 is directly above the fixing bolt 104, so that the fixing bolt 104 is threadedly connected to the bolt hole 201 to fix the arc baffle 2.

[0035] In this embodiment, the first arc plate 304 and the second arc plate 306 are both made of rubber material, and the inner surfaces of the first arc plate 304 and the second arc plate 306 are fixedly provided with a frosted layer to increase the friction coefficient of the first arc plate 304 and the second arc plate 306, thereby increasing the friction force when the first arc plate 304 and the second arc plate 306 fix the cable connection.

[0036] In this embodiment, the arcs corresponding to the first curved plate 304 and the second curved plate 306 are both equal to 120°, so that the first curved plate 304 and the second curved plate 306 can clamp cables of different diameters.

[0037] In this embodiment, the bottom surface of the rectangular frame 3 is arc-shaped, and the bottom of the rectangular frame 3 is tightly bonded to the inner surface of the sleeve 1 to ensure the stability of the rectangular frame 3 fixed to the inner surface of the sleeve 1.
