Description

Technical Field

[0001] This utility model relates to the field of mine fire prevention and extinguishing technology, specifically to a quick-deployed bundled tube protection pipeline. Background Technology

[0002] The mine fire prediction bundle monitoring system is an important component of the mine fire prevention and extinguishing technology system. Bundles and temperature measuring lines deployed in goaf areas need to be protected with 50mm diameter steel pipes to prevent breakage due to the complex environment of roof collapses. However, this protection method presents the following technical problems:

[0003] 1. Due to the limited internal space of steel pipes, the inability to cut them off at any time underground, their large size and high cost;

[0004] 2. At the same time, since a steel pipe with a diameter of 50mm weighs about 20-30kg, a lot of manpower is required when laying the steel pipe;

[0005] 3. During long-distance wiring, the temperature measuring wire and the bundle tube need to be passed through one end of the steel pipe and then out the other end. During the wiring process, the temperature measuring wire and the bundle tube are prone to entanglement due to rotation, which increases the resistance between them and the pipe wall, damages the surface of the temperature measuring wire, and causes the bundle tube to bend. Forcibly pulling the pipe over a long distance may damage the pipeline and fail to ensure the integrity of the bundle tube and the temperature measuring wire, so as to avoid affecting the fire prediction.

[0006] 4. The steel pipe is about 6m long, and the entire protective pipeline is over a hundred meters long. There are many points that need to be connected, which is a lot of work. At the same time, the steel pipe cannot be cut at any time. A professional pipe cutting machine must be used to cut it, which affects the continuity of the bundled tube system layout.

[0007] Therefore, there is an urgent need for a new type of bundled tube protection system. Utility Model Content

[0008] This utility model aims to solve the technical problems existing in the prior art. In particular, it innovatively proposes a quick-arranged bundled tube protection pipeline with a simple structure, which facilitates the placement of bundled tubes and temperature measuring wires and minimizes the possibility of entanglement or friction between bundled tubes and temperature measuring wires.

[0009] To achieve the above-mentioned objectives of this utility model, a quick-layout bundled tube protection pipeline is provided, comprising a protective tube body and a sealing strip. The protective tube body is used to accommodate the bundled tube and the temperature measuring wire. The protective tube body is made of a tough material and has a metal liner embedded inside. An opening for inserting the bundled tube and the temperature measuring wire is provided on the protective tube body along its extension direction, making its cross-section C-shaped. The sealing strip has a protruding edge for engaging with the opening. Multiple clamps are provided on the protective tube body along its extension direction to clamp the sealing strip and the protective tube body together for fixation. An anti-slip groove is recessed on the outer side of the protective tube body along its extension direction. An anti-slip hook is protruding on the inner side of the clamp ring corresponding to the anti-slip groove, and the anti-slip hook engages in the anti-slip groove.

[0010] In the above solution: the sealing strip has an H-shaped cross-section, and the upper and lower grooves of the H-shaped sealing strip are used for the C-shaped opening of the protective tube to be inserted, with a raised edge between the upper and lower grooves. This allows the C-shaped opening to be completely enclosed by the two grooves, improving the sealing performance.

[0011] In the above solution: there are two anti-slip grooves, located on opposite sides of the opening, thus improving the anti-slip effect.

[0012] In the above scheme, the opening is located on the side of the protective tube away from the coal wall. Therefore, the opening faces outwards, facilitating the insertion of the bundle tube and temperature measuring wire.

[0013] In the above scheme, the spacing of the clamps is 5 to 20 meters.

[0014] In the above solution, the width of the opening is smaller than the diameter of the bundle tube and the temperature measuring wire. The opening can be opened using hydraulic clamps before inserting the bundle tube and temperature measuring wire, thus improving the sealing effect.

[0015] In the above solution: the protective pipe body is made of glass fiber reinforced polyamide, and the clamp is made of corrosion-resistant steel or steel with anti-rust paint. Using glass fiber reinforced polyamide is corrosion-resistant, cost-effective, balances structural strength and lightweight design, saves manpower and resources, and allows for easy cutting, making operation simple and adaptable to various installation methods.

[0016] In the above scheme: the metal lining is mesh.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: the opening provided on the protective tube body allows the bundle tube and temperature measuring wire to be inserted from the side, eliminating the need for them to pass through from one end of the protective tube body to the other, thus minimizing wear on the bundle tube and temperature measuring wire; simultaneously, the provided sealing strip can close the opening, and combined with the clamp, the protective tube body and the sealing strip are joined together to form a complete tube body, preventing the bundle tube and temperature measuring wire from falling out or external substances from entering the protective pipeline, thereby improving protection safety; it solves the problems of high manual requirements, lack of continuity in the arrangement of the bundle tube step monitoring system, and easy damage to the bundle tube and temperature measuring wire in the traditional stainless steel protective tube arrangement process, while taking into account both installation efficiency and reliability.

[0021] Figure 3 This is a cross-sectional view of Embodiment 2 of this utility model. Detailed Implementation

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0023] Example 1

[0024] like Figure 1 , 2As shown, a rapid-deployment bundled tube protection pipeline includes a protective tube body 1 and a sealing strip 10. The protective tube body 1 is used to accommodate the bundled tube 3 and the temperature measuring wire. The protective tube body 1 is made of glass fiber reinforced polyamide and has a certain degree of toughness. Simultaneously, the protective tube body 1 can be a long-distance tube, eliminating the need for multiple butt joints like traditional steel pipes, thus reducing the amount of butt work. An opening 8 for inserting the bundled tube 3 and the temperature measuring wire is provided along its extension direction on the protective tube body 1, making its cross-section C-shaped. The width of the opening 8 is smaller than the diameter of the bundled tube 3 and the temperature measuring wire, preventing the bundled tube 3 and the temperature measuring wire from falling out during installation. Due to the toughness of the protective tube body 1, hydraulic clamps can be used to open the opening 8 when inserting the bundled tube 3 and the temperature measuring wire. To ensure the strength of the protective tube body 1, a mesh-like metal liner 2 is embedded inside the protective tube body 1.

[0025] Clamps 5 are installed at 10m intervals along the extension direction of the protective pipe body 1. The clamps 5 are located outside the sealing strip 10 and the protective pipe body 1, and are fixed together by tightening bolts 6. The clamps 5 are made of corrosion-resistant steel or steel with anti-rust paint.

[0026] The outer side of the protective tube body 1 is recessed along its extension direction with an anti-slip groove 4. The inner side of the clamp 5 is provided with an anti-slip hook 7 corresponding to the anti-slip groove 4, and the anti-slip hook 7 is engaged in the anti-slip groove 4. There are two anti-slip grooves 4, which are located on both sides of the opening 8.

[0027] The sealing strip 10 has slots on both the upper and lower sides, making its cross-section H-shaped. The upper and lower slots of the sealing strip 10 are used for the C-shaped opening of the protective tube 1 to be inserted.

[0028] In use, first suspend the protective tube body 1 on the coal wall with the opening 8 facing outwards. Open the opening 8 and insert the bundle tube and temperature measuring wire; after the bundle tube and temperature measuring wire are all in place, insert the sealing strip 10 from one end of the protective tube body 1 and slide it to the other end, then tighten the bolts to secure the rigid guide tube. If the bundle tube system needs to be disconnected, cut the protective tube body 1 and isolate the bundle tube using a tube cutter.

[0029] Example 2

[0030] like Figure 2 As shown, the difference between this embodiment and embodiment one is that: one side of the sealing strip 10 is provided with a protruding edge for inserting into the opening 8, which can directly block the opening 8 from the side of the protective pipe body 1, and then tighten and fix it by the clamp 5. The operation is convenient and quick, and it is suitable for the site where the air is relatively dry.
