Description

Technical Field

[0001] This utility model relates to a novel buffer-type explosion-proof box, belonging to the field of cable technology. Background Technology

[0002] High-voltage cable joints can generate sparks during use. If the connection between high-voltage cable joints is not completely sealed, an explosion can easily occur, causing a cable fire. Installing explosion-proof boxes at cable joints can isolate the electric arcs and sparks generated during use and prevent them from contacting external gases. However, over time, the sealing effect of the explosion-proof boxes inside the cable gradually decreases. In the event of an explosion at the cable joint, conventional explosion-proof boxes lack blast shock absorption devices, making the casing easily blasted open by the explosive force, posing a significant safety hazard. Furthermore, the fixing devices of the explosion-proof boxes are prone to aging over time, gradually reducing their fixing and sealing effectiveness, thus posing a safety risk. Therefore, there is an urgent need to design an explosion-proof box that can absorb the impact of an explosion and provides better fixing. Utility Model Content

[0023] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Example 1

[0025] like Figures 1-5 As shown, a novel buffer-type explosion-proof box includes a housing 1 and a fixing device 2. The housing 1 is fixed to the cable, and both ends of the housing 1 are fixed to the cable through the fixing device 2.

[0026] Reference Figure 1 , Figure 2 , Figure 4 There are two shells 1, and the shells 1 have the same structure. Multiple grooves 11 are arranged inside the shells 1. The shells 1 can fit together, and the overall shape of the fitted shell 1 is spindle-shaped. A hole is provided in the middle of the shell 1 to accommodate the cable. The shell 1 can be fixed to the cable in a fitted manner. The grooves 11 can absorb and buffer the impact generated by the explosion.

[0027] The fixing device 2 includes a mold 21 and a sealing ring 22. The mold 21 is provided with sealing rings 22 at both ends, and the mold 21 can be fixed to both ends of the housing 1. The mold 21 has a cavity inside to contain glue. After the glue solidifies, the mold 21 can be removed from the top of the housing 1.

[0028] Reference Figure 5 In this embodiment, there are two molds 21, which are semi-circular in shape. The two molds 21 are connected and fixed together by bolts 26. The two molds 21 can be combined to form a ring. Bolts 26 are provided on the side edges of the semi-circular ring of the combined mold 21. Sealing rings 22 are provided on the top and bottom of the inner side of the ring of the combined mold 21. The sealing ring 22 at the bottom of the mold 21 is connected to the housing 1, and the sealing ring 22 at the top of the mold 21 is connected to the cable.

[0029] The mold 21 has an internal cavity of a certain volume, allowing for the injection of adhesive into the cavity. After the adhesive solidifies, the mold 21 can be disassembled. One side of the mold 21 has an injection port 23 with a through hole connecting to the interior of the mold 21. A threaded connection is provided on the top of the injection port 23, and a nut 24 can be fixed to the top of the injection port 23 to seal it. The adhesive injected into the mold 21 only fills the interior of the mold 21, which is located on both sides of the housing 1.

[0030] In this embodiment, after the two housings 1 are attached and fixed to the outside of the cable, the housings 1 need to be secured. Fixing devices 2 are provided at both ends of the housings 1 to secure them. The bottom of the mold 21 of the fixing device 2 is connected to the outside of the sealing ring 22 with adhesive, and the inside of the sealing ring 22 is connected to the housing 1 with adhesive. A groove 12 is provided at the connection between the housing 1 and the sealing ring 22, extending away from the cable. The sealing ring 22, located at the bottom of the mold 21, is glued to the top of the groove 12. A fixing groove is provided at the projection of the cable onto the groove 12 of the housing 1, extending into the cable. A fixing ring 25 can be fixed inside the fixing groove, with the bottom of the fixing ring 25 located within the fixing groove and the top of the fixing ring 25 fixed within the groove 12 of the housing 1.

[0031] Reference Figure 3 The top of the mold 21 of the fixing device 2 is connected to the sealing ring 22. The sealing ring 22 on the top of the fixing mold 2 is provided with a locking groove 221. The top of the mold 21 is provided with a protrusion extending inward, which can be fixed in the locking groove 221.

[0032] The specific installation steps for the explosion-proof box are as follows:

[0033] Connect and secure the two cables using the cable connector. Confirm the housing 1, mold 21, sealing ring 22, retaining ring 25, bolt 26, nut 24, and sealant to ensure no parts are missing.

[0034] Clean the surface of the cables to prevent water or dirt from affecting the installation of the explosion-proof box. Determine the installation position of housing 1 on the cables, place both housings 1 together at the installation position, and mark the positions of the fixing grooves. The fixing grooves are set on the two cables. Adjust the two housings 1 so that they are generally spindle-shaped and their outer edges are tightly fitted.

[0035] Install a retaining ring 25 within the retaining groove. Adhesive is applied between the retaining ring 25 and the retaining groove to aid adhesion. Adhesive is also applied to the top of the retaining ring 25, which is then connected to the protrusion 12 of the housing 1 via the adhesive. This ensures that the retaining ring 25 connects the cable and the housing 1.

[0036] Install mold 21, take out two semi-circular molds 21, place the two molds 21 together at one end of housing 1, adjust the sealing ring 22, the sealing ring 22 set at the bottom of mold 21 is connected to the outer side of the protrusion 12 of housing 1 and the inner side of the bottom of mold 21 by adhesive on both sides; the sealing ring 22 set at the top of mold 21 is connected to mold 21 by locking groove 221, and the outer surface of the cable is glued by adhesive.

[0037] The two molds 21 are connected and fixed with bolts 26 to ensure the bonding effect at each connection point and to ensure that the molds 21 are assembled into a complete ring.

[0038] Mold 21 is also installed on the other end of the housing 1, and the installation steps are the same as above.

[0039] A glue gun is installed on the glue injection port 23 on one side of the mold 21. Glue is poured into the cavity inside the mold 21 until the cavity is completely filled with glue. The glue gun is then removed, and a nut 24 is installed on the glue injection port 23 to seal it. The glue is allowed to solidify. After the glue has solidified, the connection between the mold 21 and the housing 1 is disconnected. All bolts are confirmed to be tightened and the housing 1 shows no signs of loosening. Excess glue or stains on the surface of the explosion-proof box are cleaned to maintain a clean appearance.

[0040] The cooperation between the housing 1 and the fixing device 2 ensures that the explosion-proof box can effectively absorb the impact of an explosion, preventing structural damage. Furthermore, the multiple fixing structures enhance the overall fixing effect, ensuring the equipment can operate safely and stably for a long time.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model.
