Description

Technical Field

[0001] This utility model relates to the field of mining substation technology, and in particular to a corrugated explosion-proof structure for mining substations. Background Technology

[0002] Structurally, isolation measures are used to isolate the circuit from the surrounding environment, so that the heat generated by the circuit during normal operation and the electric sparks and high temperatures generated during fault conditions are all confined within a sealed enclosure to prevent the ignition of surrounding flammable and explosive gases. Flammable gases in the mining area may enter the transformer through openings. When the transformer malfunctions, the high temperature and electric sparks may ignite the flammable gases, causing an explosion. The common practice is to install a suitable enclosure outside the substation to prevent the entry of flammable gases.

[0003] Patent CN213278930U discloses a corrugated explosion-proof structure for a mining substation, including a base plate. A substation body is disposed on the upper side of the base plate, and an explosion-proof shell is disposed on the outer side of the substation body. A plurality of fixing mechanisms for fixing the explosion-proof shell are disposed on the upper side of the base plate. Each fixing mechanism includes a positioning groove disposed on the upper side of the base plate. A fixing rod is disposed through the lower side of the base plate and is slidably connected to the base plate. The upper end of the fixing rod passes through the lower side of the explosion-proof shell, and a pull ring is sleeved on the outer side of the fixing rod.

[0004] In the above technology, the rotating plate is moved towards the baffle by rotating the rotating plate, then the fixed rod is moved upward and the push rod is pushed upward so that the two support rods are retracted into the opening, and then the fixed rod is pulled out. However, there are critical areas on the surface of the substation. Under the action of external force, the explosion-proof shell is easily squeezed into the critical areas, which may cause damage to the critical areas. Therefore, this technology is innovated. Utility Model Content

[0005] The purpose of this utility model is to provide a corrugated explosion-proof structure for mining substations to solve the problem mentioned in the background art that the explosion-proof shell is easily squeezed by external forces, which may cause damage to the critical areas.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a corrugated explosion-proof structure for a mining substation, comprising an explosion-proof housing and a substation body, wherein the substation body is disposed inside the explosion-proof housing, and limit plates are provided on both sides of the explosion-proof housing, with a straight plate on the top of each of the two limit plates, and two upright plates on the top of each of the two straight plates, and an L-shaped plate on one side of each of the four upright plates, two first wrapping rings are fitted around the outside of the explosion-proof housing, and two second wrapping rings are fitted around the outside of the explosion-proof housing, with a supporting rib on one side of each of the two second wrapping rings, and a pull ring at one end of each of the two supporting ribs.

[0007] As a preferred technical solution of this utility model, the two first wrapping rings and the two second wrapping rings are fixedly connected by a plurality of restraining rods, and a U-shaped block is provided at the bottom of each of the two second wrapping rings.

[0008] As a preferred embodiment of this utility model, the multiple restraint rods are arranged at equal intervals, a support shaft is provided on one side of each of the two U-shaped blocks, and a support block is provided at one end of each of the two support ribs.

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

[0014] 1. This utility model discloses a corrugated explosion-proof structure for a mining substation. It comprises a straight plate, a vertical plate, an L-shaped plate, a first wrapping ring, restraining rods, supporting ribs, pull rings, and a second wrapping ring. The first and second wrapping rings are connected by multiple restraining rods. The bottoms of the two first wrapping rings abut against the tops of the corresponding two L-shaped plates. Positioning strips are then used to install the L-shaped plates and the first wrapping rings. The first and second wrapping rings partially cover the outer surface of the explosion-proof casing, providing protection while allowing heat dissipation within the substation to prevent overheating. The first and second wrapping rings primarily protect critical areas of the substation while avoiding excessive reinforcement of other areas, maintaining appropriate elasticity and toughness of the casing. The two pull rings are rotated sequentially to make them perpendicular to the second wrapping ring, increasing the points of leverage for operators to grip the explosion-proof casing.

By setting a positioning strip, a recessed hole, a reinforcing plate, and a support block, after the bottom of the first wrapping ring is tightly attached to the surface of the L-shaped plate, one end of the positioning strip is embedded into the interior of the recessed hole, and the two are threaded together. This can limit and fix the L-shaped plate and the first wrapping ring. With the connection of multiple restraining rods, the first and second wrapping rings are also stably installed on the outside of the explosion-proof housing. When the operator applies pressure to the pull ring, the support block moves at one end of the support shaft. When the pull ring is not in use, the pull ring is rotated in the opposite direction to make it vertically limited to the outer wall of the explosion-proof housing. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution for a corrugated explosion-proof structure for mining substations:

[0023] Example 1:

[0024] like Figure 1-3As shown, a corrugated explosion-proof structure for a mining substation includes an explosion-proof housing 1 and a substation body 2. The substation body 2 is located inside the explosion-proof housing 1. Limiting plates 3 are provided on both sides of the explosion-proof housing 1. Straight plates 5 are provided on the top of each of the two limiting plates 3. Two upright plates 6 are provided on the top of each of the two straight plates 5. L-shaped plates 7 are provided on one side of each of the four upright plates 6. Two first wrapping rings 10 and two second wrapping rings 12 are provided on the outside of the explosion-proof housing 1. Supporting ribs 16 are provided on one side of each of the two second wrapping rings 12. Pull rings 17 are provided at one end of each of the two supporting ribs 16, partially covering the outer surface of the explosion-proof housing 1. This allows both to provide protection while maintaining heat dissipation inside the substation body 2, preventing overheating. The first wrapping rings 10 and the second wrapping rings 12 mainly protect the key areas of the substation body 2, while also avoiding excessive reinforcement of other areas, maintaining appropriate elasticity and toughness of the housing. The two pull rings 17 are flipped sequentially so that they are perpendicular to the second wrapping rings 12.

[0025] Example 2:

[0026] Based on Example 1, such as Figure 1 and Figure 4 As shown, each of the four L-shaped plates 7 has a positioning strip 8 on one side, each of the two first wrapping rings 10 has two recessed holes on one side, each of the four upright plates 6 has a reinforcing plate 9 fixedly installed on one side, the bottom of the four reinforcing plates 9 is fixedly connected to the top of the two upright plates 5 respectively, and the top of the two limiting plates 3 is threadedly connected to the substation body 2 by two limiting bolts 4 respectively. This utility model is a corrugated explosion-proof structure for a mining substation. By setting the positioning strip 8, recessed holes, reinforcing plates 9 and support blocks 15, after the bottom of the first wrapping ring 10 is tightly attached to the surface of the L-shaped plate 7, one end of the positioning strip 8 is embedded into the inside of the recessed hole and the two are threadedly connected, so that the L-shaped plate 7 and the first wrapping ring 10 can be limited and fixed. With the connection of multiple restraining rods 11, the first wrapping ring 10 and the second wrapping ring 12 are also stably installed on the outside of the explosion-proof housing 1.

[0027] Working principle: The structure uses isolation measures to separate the circuit from the surrounding environment. This confines the heat generated during normal operation and the electrical sparks and high temperatures during fault conditions within a sealed enclosure, preventing the ignition of surrounding flammable and explosive gases. Flammable gases in the mining area can enter the transformer through openings. When the transformer malfunctions, the high temperature and electrical sparks can ignite these gases, causing an explosion. A common practice is to install a suitable enclosure on the outside of the substation to prevent the entry of flammable gases. In the above technology, the substation surface has critical areas; under external forces, the explosion-proof enclosure is easily damaged. The key area is squeezed, which may cause damage to the critical area. Therefore, this technology is innovated. The explosion-proof shell 1 is made of cast aluminum alloy, which has light weight and good mechanical strength, and also has a certain degree of corrosion resistance. The shell material must be able to withstand the pressure, impact and explosion fluctuations that may occur inside the equipment to ensure that it will not be damaged in the event of a failure. The first wrapping ring 10 and the second wrapping ring 12 are connected by multiple restraining rods 11. The bottom of the two first wrapping rings 10 respectively abuts against the top of the two corresponding L-shaped plates 7. Then, the positioning strips 8 are used to connect the L-shaped plates 7 to the first wrapping rings 12. With the installation of the first and second wrapping rings 10, the explosion-proof housing 1 can partially cover its outer surface. This allows for protection while maintaining heat dissipation within the substation body 2, preventing overheating. The first and second wrapping rings 10 primarily protect critical areas of the substation body 2, while also preventing excessive reinforcement of other areas, maintaining appropriate elasticity and toughness of the housing. The two pull rings 17 are then flipped so that they are perpendicular to the second wrapping ring 12, increasing the leverage points for the operator to grip the explosion-proof housing 1. The bottom of the first wrapping ring 10 is flush with the surface of the L-shaped plate 7. After the surfaces are tightly fitted, one end of the positioning strip 8 is embedded into the recessed hole, and the two are threaded together, thereby limiting and fixing the L-shaped plate 7 and the first wrapping ring 10. With the connection of multiple restraining rods 11, the first wrapping ring 10 and the second wrapping ring 12 are securely installed on the outside of the explosion-proof housing 1. When the operator applies pressure to the pull ring 17, the support block 15 moves at one end of the support shaft 14. When the pull ring 17 is not in use, the pull ring 17 is rotated in the opposite direction to make it vertically limited to the outer wall of the explosion-proof housing 1. The reinforcing plate 9 is located on one side of the upright plate 6, which enhances the support strength of the upright plate 6.
