Description

Technical Field

[0001] The utility model relates to the technical field of pipeline protection devices, in particular to a fire water pipe crossing protection device. Background Art

[0002] During the firefighting and rescue process, when there is no municipal fire pipeline around the rescue site, the water volume carried by the fire truck cannot meet the on-site firefighting needs, especially when a large fire occurs, firefighters need to fetch water from nearby reservoirs and rivers over long distances. The water fetching equipment usually uses a high-power water pump, and the water delivery pipeline is usually made of polyurethane and polyvinyl chloride materials. The pipe diameter reaches more than 300mm, and the pressure in the pipe reaches 0.8MPa or higher. When long-distance water supply and fire fighting are carried out in the city, the water fetching distance is sometimes as long as several kilometers. Firefighting water supply pipelines are usually laid along urban roads, and it is inevitable that they will cross urban road intersections. During the water supply process, motor vehicles and non-motor vehicles cannot pass, causing traffic congestion and travel inconvenience. At the same time, the passage of vehicles is also prone to crushing and damaging the laid water supply pipelines, affecting the normal use of the firefighting water supply pipelines. High-pressure pipeline damage is also very likely to cause harm to pedestrians, posing a huge safety hazard.

[0003] At present, some firefighting systems use sandbags to build temporary bridges to assist non-motorized vehicles to pass through. However, firefighting sandbags cannot be fixed directly above the water supply pipes. Non-motorized vehicles can easily scratch the water supply pipes during passage, affecting water supply and disaster relief. Some firefighting systems use welded entire bridges to assist non-motorized vehicles to pass through. Due to the large diameter of the pipes, the length of the bridge is 6-7 meters according to the slope. The weight of the bridge is large, and it is inconvenient to transport and carry. Especially when the water supply pipes cross multiple intersections, multiple sets of bridges need to be transported, which requires the transportation and installation of rescue vehicles and personnel, affecting the implementation of firefighting.

[0004] Therefore, a portable fire-fighting pipeline crossing protection device that can be disassembled and assembled is needed. Utility Model Content

[0005] In view of the above-mentioned deficiencies in the prior art, the purpose of the utility model is to provide a portable fire pipe crossing protection device to solve the problem of small motor vehicles and non-motor vehicles safely passing through fire pipes.

[0006] In order to solve the above problems, the utility model adopts the following technical solutions.

[0007] A portable fire-fighting pipeline crossing protection device comprises a bridge frame structure, expansion bolt reserved holes, fire-fighting pipeline reserved holes, wear-resistant hard rubber, solar flashing lights, positioning pin holes, and stainless steel bearing hinges. The device is characterized in that the bridge frame structure is composed of two components in one group. The bridge frame structure is an oblique cone with a low front and a high rear. The upper surface of one end is in close contact with the road surface, and the other end is the end of the fire-fighting pipeline reserved hole. The fire-fighting pipeline reserved hole is opened at the high end of the bridge frame structure. The top and bottom of the fire-fighting pipeline reserved hole are at a certain distance from the top and bottom surfaces of the bridge frame structure to protect the overall strength of the bridge frame structure. The wear-resistant hard rubber is evenly distributed on the upper surface of the bridge frame structure. The surface of the bridge is made of rubber material. The stainless steel bearing hinge is located at the top of the bridge frame structure. The two bridge frame structures are connected by bolts to form a complete fire protection device.

[0008] Preferably, the bridge frame structure is a hollow structure, which can effectively reduce the overall weight of the bridge, has the function of sound absorption and noise reduction, and reduces the weight of bridges of the same length.

[0009] Preferably, the stainless steel bearing hinge is used to connect the left and right bridge frame structures. The two bridge frame structures can be folded and placed via the stainless steel bearing hinge, effectively reducing the length of the overall structure and facilitating storage and transportation.

[0010] Preferably, the reserved hole for the fire-fighting pipe is usually circular, and can also be set to an elliptical or rectangular shape. When set to an elliptical shape, the circumference of the ellipse must be kept consistent with the circumference of the water supply pipe. The elliptical structure can effectively reduce the height of the high end of the oblique cone, reduce the inclination angle of the overall structure, and reduce the length of the frame structure.

[0011] Preferably, the inner wall of the reserved hole for the fire-fighting pipe is lined with a flexible material for protection, so as to reduce the weight of small motor vehicles and non-motor vehicles passing through, which directly acts on the inner wall of the reserved hole for the fire-fighting pipe and causes wear on the outer wall of the fire-fighting pipe, thereby playing a buffering role.

[0012] Preferably, solar strobe lights are evenly embedded in the upper surface of the bridge frame structure. The solar strobe lights are sheet-like structures, and the solar panels and flashing lights are an integral structure, which are used to guide passing small motor vehicles and non-motor vehicles at night.

[0013] Preferably, two expansion bolt reserved holes are provided on one side of the front portion of the bridge frame structure, and the expansion bolt reserved holes are circular holes, through which the expansion bolts are fixed to the road surface.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1) The utility model can provide a good protection for the passing fire-fighting pipes by setting the reserved holes for the fire-fighting pipes, prevent the fire-fighting pipes from being damaged by being crushed by passing vehicles, ensure that the fire-fighting pipes can normally supply water to extinguish the fire when a fire occurs, and improve the reliability and safety of the fire-fighting system; it is also convenient for small motor vehicles, non-motor vehicles and pedestrians to pass normally during the blocking period of the intersection, and is convenient for the surrounding residents to travel.

[0016] 2) Solar flashing lights are installed on the upper surface of the bridge frame structure to guide passing small motor vehicles and non-motor vehicles, prevent vehicles from accidentally running over the fire water supply pipes, and further protect the fire water supply pipes.

[0017] 3) The bridge frame structure can be assembled and disassembled, and is convenient for transportation and installation. BRIEF DESCRIPTION OF THE DRAWINGS

The bridge frame structure 1 is an oblique cone with a low front and a high rear, with an upper surface of one end close to the road surface and the other end being the fire-fighting pipeline reserved hole 7. The wear-resistant hard rubber 3 is evenly distributed on the upper surface of the bridge frame structure 1. The wear-resistant hard rubber 3 is in the shape of a long strip and has the same width as the bridge frame structure 1. The width of the bridge frame structure 1 is 600 mm and 900 mm. The left and right sides of the long side of the bridge frame structure 1 are A locating pin hole 6 is provided on the side, and the locating pin hole 6 is used for splicing two road crossing protection devices. The locating pin hole 6 is fixed by an L-shaped metal connecting rod 8 connected in series with the locating pin hole. Specifically, when a larger width is required, the locating pin hole 6 is used for assembly. The locating pin holes 6 are distributed on the left and right sides of the bridge frame structure 1. The locating pin holes 6 are through-long holes, which are connected by the L-shaped metal connecting rod 8. A groove is provided on one side of the locating pin hole 6. When connected, the short side of the L-shaped metal connecting rod 8 is embedded in the groove. The bridge frame structure 1 is made of rubber material, and the stainless steel bearing hinge 4 is located at the top of the bridge frame structure 1. The stainless steel bearing hinge 4 is fixed to the bridge frame structure 1 by bolts.

[0026] The bridge frame structure 1 is a hollow structure with a certain number of small holes evenly arranged. The larger the size of the bridge frame structure 1, the more small holes it contains. The hollow structure setting can effectively reduce the weight of the portable fire pipe crossing protection device, facilitate the transportation, handling and installation of the protection device, and play a buffering role when small motor vehicles pass through the protection device, and have the function of silencing and reducing noise.

[0027] The stainless steel bearing hinge 4 is used to splice the front and rear two bridge frame structures 1.

[0028] The fire-fighting pipe reserved hole 7 is usually circular, and the diameter of the circle is slightly larger than the diameter of the water supply pipe, which is conducive to playing a buffering role in the water supply process of the water supply pipe. The fire-fighting reserved hole 7 can also be set to an ellipse. When it is set to an ellipse, the circumference of the ellipse should be kept consistent with the circumference of the water supply pipe, which can effectively reduce the height of the rear part of the bridge frame structure 1 and reduce the overall length of the bridge frame structure 1. The inner wall of the fire-fighting pipe reserved hole 7 is protected by a flexible material buffer pad to reduce the wear on the fire-fighting pipe and play a buffering role.

[0029] A warning sign is provided on the upper surface of the bridge frame structure 1, and the warning sign is powered by solar energy. In this embodiment, the warning sign is a solar strobe light 5 evenly embedded on the upper surface of the bridge frame structure 1, and the solar strobe light 5 is a thin sheet structure, which is used to warn passing small motor vehicles and non-motor vehicles.

[0030] Two expansion bolt reserved holes are arranged on one side of the front part of the bridge frame structure.
