Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for thermal engineering, and specifically to a trench protection device for thermal engineering. Background Technology

[0002] In heating engineering, trench excavation is a crucial preliminary step in pipeline laying. However, during the period from trench excavation to pipeline laying, and also during the pipeline's use after laying, the trench faces numerous issues requiring protection.

[0003] Currently available trench protection devices have several shortcomings. Some lack sufficient protective performance, failing to effectively resist external impacts or prevent debris from falling into the trench and damaging the pipeline. Others involve cumbersome installation and dismantling processes, consuming significant manpower and time, thus hindering construction efficiency. Still others are ill-suited for trenches of different sizes and shapes, exhibiting poor versatility. For instance, some existing protective devices simply employ protective nets or covers, which are easily damaged by significant external forces, such as accidental vehicle run-over, failing to provide the intended protection. Utility Model Content

[0004] In view of the problems existing in the above-mentioned trench protection devices, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a trench protection device for thermal engineering, which solves the problems of insufficient protective performance, cumbersome installation and disassembly, and poor versatility of the protection device.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A trench protection device for thermal engineering includes multiple protective plates. Multiple openings are fixedly provided on the top and bottom of the multiple protective plates. Bolts are threaded into the multiple openings. The multiple protective plates are fixedly connected by bolts. An elastic pad is fixedly provided at the bottom of one of the protective plates. A fixing groove is fixedly provided in the elastic pad. A spring is fixedly provided in the fixing groove. Multiple elastic strips are fixedly provided on the top of another protective plate. An insulation layer is fixedly provided inside the multiple protective plates.

[0008] Preferably, the insulation layer comprises an aerogel felt layer and a polyurethane foam layer, which are fixedly connected.

[0009] Preferably, the thickness of both the aerogel felt layer and the polyurethane foam layer is 2 mm.

[0010] Preferably, one of the protective panels is provided with a reflective strip on one side.

[0011] Furthermore, the reflective strip is a microprism-type reflective strip.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] This utility model features a protective plate made of high-strength aluminum alloy with a wear-resistant and corrosion-resistant coating. The buffer components at the bottom and top edges can effectively absorb and disperse external impacts, protecting the trench and pipes. The inner insulation layer can also reduce heat loss and improve heat transfer efficiency. The protective plate can be quickly connected and disassembled, greatly improving construction efficiency.

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] This utility model discloses a trench protection device for thermal engineering.

[0022] This utility model provides, for example Figure 1-3The illustrated trench protection device for thermal engineering includes multiple protective plates 1. Multiple openings 2 are fixedly formed at the top and bottom of each protective plate 1. Bolts 3 are threaded into the openings 2. The protective plates 1 are fixedly connected by the bolts 3. An elastic pad 4 is fixedly formed at the bottom of one protective plate 1, and a fixing groove 5 is fixedly formed within the elastic pad 4. A spring 6 is fixedly formed within the fixing groove 5. Multiple elastic strips 7 are fixedly formed at the top of another protective plate 1. An insulation layer 8 is fixedly formed within the multiple protective plates 1. During installation, first, select an appropriate number of protective plates 1 according to the length and shape of the trench, transport the protective plates 1 to the side of the trench, and then connect adjacent protective plates 1 using the bolts 3. When connecting the pipe trench, if the trench has a certain slope or special shape, the angle can be adjusted by replacing the protective plate 1 to ensure a tight fit. After the connection is completed, the elastic pad 4 and elastic strip 7 are placed on the trench, with the bottom of the protective plate 1 in contact with the bottom of the trench, providing a buffering and stabilizing effect. During use, the reflective strip 11 on the outside of the protective plate 1 can warn pedestrians and vehicles at night or in low light conditions to prevent collisions. When debris falls or is impacted by external forces, the elastic strip 7 can absorb and disperse the impact force, protecting the trench and internal pipes. At the same time, the insulation layer 8 on the inside of the protective plate 1 can reduce heat loss and improve heat transfer efficiency.

[0023] For better heat retention, such as Figure 3 As shown, the insulation layer 8 includes an aerogel felt layer 9 and a polyurethane foam layer 10, which are fixedly connected for better insulation performance.

[0024] In order to improve the service life of the insulation layer 8, such as Figure 3 As shown, the aerogel felt layer 9 and the polyurethane foam layer 10 are both 2mm thick, in order to improve the service life of the insulation layer 8.

[0025] And in order to warn passersby, such as Figure 1 As shown, one of the protective panels 1 has a reflective strip 11 fixed on one side to warn passersby.

[0026] Finally, to make reflective strip 11 more prominent, such as Figure 1 As shown, the reflective strip 11 is a microprism type reflective strip 11, which makes the reflective strip 11 more obvious.

[0027] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
