Description

Technical Field

[0001] The utility model belongs to the technical field of explosion-proof wire pipes, and particularly relates to a spreading mechanism for explosion-proof wire pipes in a hazardous waste room. Background Technique

[0002] In many high-risk environments, such as petrochemical plants, dusty environments, and lithium battery production areas, conventional iron pipes or PVC pipes are prone to electrical circuit damage due to their poor strength and sealing performance, which can easily lead to electric sparks or even explosions. An explosion-proof wire pipe is a safety device used in special dangerous occasions, aiming to prevent explosions caused by sparks or heat generated by electrical circuits. Specifically, it is sleeved on the electric wire and seals the wire to prevent the wire from being directly exposed in the flammable and explosive dangerous environment.

[0003] When the distance between two exposed connectors of the existing electric wire is very close and they are located at two different positions, when the existing explosion-proof wire pipe is directly sleeved on the exposed electric wire, the explosion-proof wire pipe will be twisted along with the electric wire. Over time, the parts with larger bending angles in the explosion-proof wire pipe will age and crack, thus failing to effectively protect the electric wire. Due to the special environment where the explosion-proof wire pipe is located, it is not convenient to replace the explosion-proof wire pipe. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is that the explosion-proof wire pipe is twisted along with the electric wire for a long time, and the parts with larger bending angles are prone to aging and cracking, and cannot effectively protect the electric wire.

[0005] To solve the above technical problems, the technical scheme adopted by the utility model is as follows: a spreading mechanism for explosion-proof wire pipes in a hazardous waste room, including an outer pipe sleeve, through holes are arranged on the outer pipe sleeve and are arranged at equal intervals along the direction of the outer pipe sleeve. It also includes a deformation positioning component and an extension protection component. The deformation positioning component is arranged between the inner walls of the outer pipe sleeve, and the extension protection component is arranged at both ends of the outer pipe sleeve. The deformation positioning component is used to ensure the stability of the outer pipe sleeve after deformation, and the extension protection component is used to protect the pipeline leaking out of the outer pipe sleeve.

[0006] Further, the deformation positioning component includes an inner frame, a guide rail, a slider, an adjusting rod, and a positioning column, where:

[0007] The inner frame is fixedly connected to the inner wall of the outer pipe sleeve, the guide rail is fixedly connected to the inner wall of the outer pipe sleeve, the slider is slidably arranged on the guide rail, the adjusting rod is movably connected to the outer side wall of the slider, and one end of it vertically penetrates and is slidably connected to the end of the inner frame, and the positioning column is threadedly connected to the top of the inner frame.

[0008] Further, the adjusting rod is provided with positioning grooves which are linearly arranged. The positioning posts are adapted to the positioning grooves. Limiting holes are provided on both sides of the inner frame. Limiting blocks are provided on both sides of the free end of the adjusting rod, and one end of the limiting block extends into the limiting hole.

[0009] Further, the extension protection assembly includes an extension plate, a semi-ring and a convex block, wherein:

[0010] The extension plate is fixedly connected to the end of the outer sleeve. The semi-rings are fixedly connected to the outer side wall of the extension plate and are linearly arranged. The convex blocks are fixedly connected to the extension plate and are symmetrically distributed up and down. The semi-rings and the convex blocks are alternately arranged.

[0011] Further, the extension plate is arc-shaped, and the convex block is provided with a hollow through hole.

[0012] Further, the outer sleeve is made of an elastic material.

[0013] After adopting the above structure, the beneficial effects of the present utility model are as follows:

[0014] (1) The outer tube sleeve made of an elastic material can be applied to explosion-proof wire tubes with different curvatures, and the arrangement of the through holes is conducive to the deformation of the outer tube sleeve;

[0015] (2) Through the deformation treatment of the outer tube sleeve, the positioning post can slide on the inner frame, and the adjusting rod is locked and positioned by the positioning post to ensure its fixation after deformation, so as to better protect the explosion-proof wire tube;

[0016] (3) Through the arrangement of the extension plate and the semi-ring, the protection length of the explosion-proof wire tube can be increased, so that the part of the explosion-proof wire tube leaving the outer tube sleeve is still restricted;

[0017] (4) The hollow through convex block can pass through the cable tie to assist in locking and limiting the explosion-proof wire tube, ensuring the limiting and protecting effect on the explosion-proof wire tube. Description of the Drawings

[0025] As Figure 1-2 shown, a spreading mechanism for explosion - proof conduit pipes in a hazardous waste storage room includes an outer pipe sleeve 1. The outer pipe sleeve 1 is provided with through - holes 2, and they are arranged at equal intervals along the direction of the outer pipe sleeve 1. The outer sleeve is made of elastic material. It also includes a deformation positioning component and an extension protection component. The deformation positioning component is arranged between the inner walls of the outer pipe sleeve 1, and the extension protection component is arranged at both ends of the outer pipe sleeve 1.

[0026] The explosion - proof conduit pipe after passing through the inside of the outer pipe sleeve 1 is effectively protected by the deformation positioning component, and the part of the explosion - proof conduit pipe outside the outer sleeve is extended and positioned for protection by the extension protection component.

[0027] As Figure 1-5 shown, in order to effectively protect the bent part of the explosion - proof conduit pipe, the deformation positioning component includes an inner frame 3, a guide rail 4, a slide block 5, an adjusting rod 6 and a positioning column 7. The inner frame 3 is fixedly connected to the inner wall of the outer pipe sleeve 1. The guide rail 4 is fixedly connected to the inner wall of the outer pipe sleeve 1. The slide block 5 is slidably arranged on the guide rail 4. The adjusting rod 6 is movably connected to the outer side wall of the slide block 5, and one end of it vertically penetrates the end of the inner frame 3 and is slidably connected to it. The positioning column 7 is threadedly connected to the top of the inner frame 3. The adjusting rod 6 is provided with positioning grooves 8, and they are arranged linearly. The positioning column 7 and the positioning grooves 8 are adapted to each other. Limit holes 9 are provided on both sides of the inner frame 3, and limit blocks 10 are provided on both sides of the free end of the adjusting rod 6. One end of the limit block 10 extends into the limit hole 9.

[0028] By deforming the outer sleeve and locking and positioning the adjusting rod 6, the explosion - proof conduit pipe can be effectively protected, increasing its service life.

[0029] As Figure 1-5As shown, the extended protection component includes an extension plate 11, a semi-ring 12, and a bump 13. The extension plate 11 is fixedly connected to the end of the outer sleeve. The semi-ring 12 is fixedly connected to the outer side wall of the extension plate 11 and is arranged linearly. The bump 13 is fixedly connected to the extension plate 11 and is symmetrically distributed up and down. The semi-ring 12 and the bump 13 are arranged alternately.

[0030] Through the extension of the extension plate 11 and the setting of the semi-ring 12, partial protection can be provided for the straight part of the explosion-proof wire tube.

[0031] Among them, the extension plate 11 is arc-shaped, and the bump 13 is hollow and through.

[0032] During specific use, the explosion-proof wire tube sleeved with wires is passed through the gap between the extension plate 11 and the semi-ring 12, and then continued to be inserted into the inner part of the outer tube sleeve 1 until it extends out from the extension plate 11 on the other side. According to the situation, the shape of the outer sleeve is adjusted. When the outer sleeve deforms, the adjusting rod 6 slides in the side frame, and the slider 5 slides on the guide rail 4. When the adjusting rod 6 slides, it drives the limit block 10 to slide in the limit hole 9. After the adjustment is completed, the positioning column 7 is screwed into the corresponding positioning groove 8, and the shape of the outer sleeve can be positioned. The outer sleeve can protect the explosion-proof wire tube. The cable tie can be passed through the bump 13 to assist in positioning the straight section of the explosion-proof wire tube to prevent it from moving.

The scope of the present invention is defined by the appended claims and their equivalents.
