Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting pipelines, in particular to a corrosion-resistant fire-fighting pipeline. Background Art

[0002] Fire-fighting pipelines refer to pipeline materials used for fire-fighting, connecting fire-fighting equipment and appliances, and conveying fire-fighting water, gas or other media. Due to special requirements, the thickness and material of fire-fighting pipelines have special requirements and are painted red with paint to convey fire-fighting water. Since fire-fighting pipelines are often in a static state, strict requirements are imposed on the pipelines. The pipelines need to have high pressure resistance and good corrosion resistance. However, when the prior art performs anti-corrosion settings on fire-fighting pipelines, it often only applies an anti-corrosion layer. Although the corrosion resistance of fire-fighting pipelines is improved to a certain extent, a single anti-corrosion layer cannot significantly improve the corrosion resistance of fire-fighting pipelines. When encountering weather such as wind and rain, it will also cause damage to fire-fighting pipelines.

[0003] For example, a corrosion-resistant fire-fighting pipeline is disclosed in Chinese Patent (Publication No.: CN217634311U), which includes a box body. A fixed screw seat and a first screw hole are installed on the top of the box body. The interior of the box body includes an anti-corrosion device, a moving device and a fixing device. The anti-corrosion device is composed of an anti-corrosion layer and a protective layer; the moving device includes a rotating handle, the rotating handle is connected to a threaded rod, the threaded rod is connected to a gear, the gear is connected to a rack, the gear is connected to a connecting rod, the connecting rod is connected to a chute and a fixed rod, and a moving plate is installed on the fixed rod; the fixing device includes an L-shaped fixing plate and a half plate. The L-shaped fixing plate is provided with a chute and a rack. The half plate is provided with a through hole. The half plate is connected to the threaded rod. Fixing plates are installed on the upper and lower surfaces of the half plate. Thus, the utility model can not only improve the anti-corrosion performance of the fire-fighting pipeline, but also improve the fixing effect on the half plate, the protective layer and the fire-fighting pipeline.

[0004] The above-mentioned corrosion-resistant fire-fighting pipeline still has certain deficiencies. During the movement of the moving plate, it will come into contact with the fixing plate, thereby pushing the fixing plate to move. And the moving distance of the moving plate is equal to the moving distance of the gear on the rack. When the above-mentioned moving distance reaches the maximum value, the two half plates come into contact. This is not only complex in operation, but also low in fixing efficiency. It is necessary to rotate two rotating handles to fix, which is time-consuming and laborious and affects the fixing effect. Therefore, this application proposes a corrosion-resistant fire-fighting pipeline to solve the above problems. Summary of the Utility Model

[0021] Furthermore, the weather-resistant layer is made of epoxy resin, the heat-insulating layer is made of EPE, the first corrosion-resistant layer is made of perchloroethylene, and the second corrosion-resistant layer is made of polyurethane paint.

Detailed implementation

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figure 1 , the corrosion-resistant fire pipeline in this embodiment includes an outer shell 1 and a fire pipeline body 2 located inside the outer shell 1. A fixing mechanism 4 for fixing the fire pipeline body 2 is provided inside the outer shell 1. The fire pipeline body 2 is fixed by the fixing mechanism 4, and a protection mechanism 3 is fixed on the outer surface of the fire pipeline body 2 to improve the corrosion resistance of the fire pipeline body 2 through the protection mechanism 3.

[0033] Among them, a round hole is opened on the front surface of the outer shell 1, and the fire pipeline body 2 is slidably connected to the inside of the round hole, which is convenient for the fixing mechanism 4 to fix the fire pipeline body 2.

[0034] Please refer to Figures 2 - 3 , in order to facilitate the fixing of the fire pipeline body 2, the fixing mechanism 4 in this embodiment includes a rotating component and a limiting component. The rotating component includes two threaded rods 404 rotatably connected between the left and right sides of the inner cavity of the outer shell 1 through bearing seats, a second gear 403 fixed on the outer surface of the rear threaded rod 404, a first gear 402 meshing with the outer surface of the second gear 403, a rotating rod 401 fixed inside the first gear 402 and penetrating and extending to the outside of the outer shell 1, and a transmission component 407 arranged on the outer surfaces of the two threaded rods 404. The rotating rod 401 and the first gear 402 rotate together to drive the second gear 403 and the rear threaded rod 404 to rotate together. The rear threaded rod 404 drives the front threaded rod 404 to rotate together through the transmission component 407.

[0035] The limiting component includes two moving blocks 405 threadedly connected to the outer surfaces of the two threaded rods 404 and clamping blocks 406 fixed on the opposite sides of the two moving blocks 405. The fire pipeline body 2 is fixed by the cooperation of the two clamping blocks 406.

[0036] Among them, the transmission component 407 includes a sprocket fixed on the outer surface of the threaded rod 404. The outer surfaces of the two sprockets are drivingly connected by a chain. The rear threaded rod 404 drives the front threaded rod 404 to rotate through the transmission component 407.

[0037] In addition, a rotating handle is fixed on the left side of the rotating rod 401 for facilitating the rotation of the rotating rod 401. A through hole is provided on the left side of the housing 1. The rotating rod 401 is rotatably connected to the inside of the through hole through a bearing, which increases the stability of the rotating rod 401 during rotation. The thread of the threaded rod 404 has two sections with opposite thread directions. By rotating the threaded rod 404, the two clamping blocks 406 are driven to move relatively or away from each other simultaneously.

[0038] Furthermore, T-shaped blocks are fixed on both the front and rear sides of the moving block 405. T-shaped grooves are provided on both the front and rear sides of the inner cavity of the housing 1. The T-shaped blocks are slidably connected to the inside of the T-shaped grooves, which increases the stability of the moving block 405 during movement. Arc-shaped grooves are provided on the opposite sides of the two clamping blocks 406. The clamping blocks 406 are in contact with the fire pipeline body 2 through the arc-shaped grooves, and the fire pipeline body 2 is clamped and fixed by the clamping blocks 406.

[0039] In the fixing mechanism 4 of this embodiment, the fire pipeline body 2 is inserted into the housing 1. The rotating handle is rotated to drive the rotating rod 401 and the first gear 402 to rotate together, driving the second gear 403 and the rear threaded rod 404 to rotate together. The rear threaded rod 404 drives the front threaded rod 404 to rotate together through the transmission component 407, causing the two moving blocks 405 to move relatively simultaneously and driving the clamping blocks 406 to move together to fix the fire pipeline body 2. The fixing is convenient and has a good fixing effect.

[0040] Please refer to Figure 4 , in order to improve the performance of the fire pipeline body 2, the protection mechanism 3 in this embodiment includes a weather-resistant layer 301 fixed on the outer surface of the fire pipeline body 2, a heat-insulating layer 302 fixed on the outer surface of the weather-resistant layer 301, a first corrosion-resistant layer 303 fixed on the outer surface of the heat-insulating layer 302, and a second corrosion-resistant layer 304 fixed on the outer surface of the first corrosion-resistant layer 303.

[0041] Among them, the weather-resistant layer 301 is epoxy resin, which has excellent chemical resistance, especially alkali resistance, strong film adhesion, especially to metals, and has good heat resistance and electrical insulation. The heat-insulating layer 302 is made of pearl cotton, which has many advantages such as moisture-proof, shock-proof, sound-insulating, heat-insulating, good plasticity, strong toughness, recyclable, environmentally friendly, and strong impact resistance. It also has good resistance. The first corrosion-resistant layer 303 is perchloroethylene, which has good electrical and film-forming properties, extremely stable chemical properties, corrosion resistance, and water resistance. The second corrosion-resistant layer 304 is polyurethane paint, which has good adhesion, wear resistance, water resistance, moisture-proof, and the function of resisting erosion by acid and alkali media, and has good corrosion resistance.

[0042] The protection mechanism 3 in this embodiment is composed of a weather-resistant layer 301, a heat-insulating layer 302, a first corrosion-resistant layer 303, and a second corrosion-resistant layer 304, which improves the weather resistance, heat insulation performance, and corrosion resistance of the fire pipeline body 2, and is beneficial to the long-term use of the fire pipeline body 2.

[0043] The working principle of the above embodiment is as follows:

[0044] (1) Insert the fire pipeline body 2 into the interior of the outer shell 1 through the round hole, and rotate the rotary handle. The rotary handle drives the rotating rod 401 and the first gear 402 to rotate together. The first gear 402 drives the second gear 403 and the rear end threaded rod 404 to rotate together. When the rear end threaded rod 404 rotates, it drives the rear end sprocket to rotate. The rear end sprocket drives the front end sprocket and the front end threaded rod 404 to rotate together through the chain. Since the thread directions of the two sections of the threaded rod 404 are opposite, the rotation of the threaded rod 404 drives the two moving blocks 405 to move relatively at the same time. The moving block 405 drives the clamping block 406 to move together, and the fire pipeline body 2 is fixed by the two clamping blocks 406. The fixing is convenient and the fixing effect is good.

[0045] (2) The protection mechanism 3 is composed of a weather-resistant layer 301, a heat-insulating layer 302, a first corrosion-resistant layer 303, and a second corrosion-resistant layer 304. The weather-resistant layer 301 is epoxy resin, which has excellent chemical resistance, especially alkali resistance, strong film adhesion, good heat resistance and electrical insulation. The heat-insulating layer 302 is EPE, which has many advantages such as moisture-proof, shock-proof, sound-insulating, heat-insulating, good plasticity, strong toughness, recyclable, environmentally friendly, and strong impact resistance. The first corrosion-resistant layer 303 is perchloroethylene, which has good electrical and film-forming properties and is corrosion-resistant. The second corrosion-resistant layer 304 is polyurethane paint, which has good adhesion, wear resistance, water resistance, moisture resistance, and the function of resisting erosion by acid and alkali media, and has good corrosion resistance. It improves the weather resistance, heat insulation performance, and corrosion resistance of the fire pipeline body 2, and is beneficial to the long-term use of the fire pipeline body 2.
