[0001] This utility model belongs to the field of fire-fighting equipment technology, specifically relating to a fire hose support for nuclear power plants. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] Fire hoses are flexible tubes used to transport high-pressure fire water or flame-retardant liquids such as foam. Fire hoses are usually placed on fire hose racks. According to the installation method of fire hoses, fire hose racks can be divided into reel type, hanging type and bracket type.

[0004] Conventional fire hose supports are typically placed inside fire hydrant boxes. These boxes are large, requiring the fire hose reel to be opened for use, which limits their application in the confined spaces of nuclear power plants. Furthermore, current fire hose supports lack earthquake-resistant design. Nuclear power plants, with their specific requirements, necessitate earthquake-resistant supports for storing fire hoses and nozzles. In the event of an earthquake, these supports must maintain structural integrity and remain operational. Damage to the supports due to earthquake vibrations will affect the use of fire hoses. Earthquakes in nuclear power plants can cause equipment damage and potentially fires; damage to the fire hose supports could prevent timely firefighting. Utility Model Content

[0005] To address the aforementioned issues, this utility model provides a fire hose support for nuclear power plants that can be installed in confined spaces and has earthquake resistance. In the event of an earthquake, it can ensure structural integrity, prevent damage, and allow for normal use in timely firefighting.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fire hose support for a nuclear power plant includes a mounting base, a support body, and a clamp. The support body is mounted at one end of the mounting base, and the clamp is mounted at one end of the support body. A shock-absorbing ring is provided at the connection point between one end of the support body and the mounting base. The clamp includes a clamp, a pin, and a fixing plate. The clamp is fitted onto the fire hose nozzle, and a pin is provided at one end of the clamp. An elastic buffer pad is provided on the inner side of the clamp.

[0008] Furthermore, the main body of the support includes a support shell, a support rod, a support platform, a water hose hanging rod, and a dust cover, with the dust cover installed at the lower end of the support shell.

[0009] Furthermore, one end of the bracket housing is rotatably connected to the mounting base, and the other end of the bracket housing is connected to the fixing plate.

[0010] Furthermore, a support rod is provided at one end of the bracket housing, and a support platform is provided at the other end of the bracket housing.

[0011] Furthermore, several hose hanging rods are spaced apart between the support rod and the support platform, and these hose hanging rods are arranged along the length of the support shell.

[0012] Furthermore, a water hose is installed on the hose hanger, and one end of the water hose is connected to a fire hose nozzle.

[0013] Furthermore, one end of the hose hanging rod is movably connected to the support rod, and the other end of the hose hanging rod rests on the support platform.

[0014] Furthermore, the end of the pin and the clamp are connected by a chain.

[0015] Furthermore, the pin is a D-type pin.

[0016] Furthermore, the elastic buffer pad has anti-slip textures on the contact surface with the fire hose.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are:

[0018] This utility model enables the installation of fire hoses by using a mounting base, a support body, and clamps. It eliminates the need for a large fire box, allowing the fire hose to be placed on the support body and the fire nozzle to be installed on the clamp. When not in use, the fire nozzle is fixed and secured to a wall or steel structure by the mounting base. This allows for installation in small areas, saving space and making it convenient to access.

[0019] This invention effectively improves the seismic resistance of fire hose supports by installing a silicone shock-absorbing ring between one end of the support body and the mounting base. This ensures the normal operation of the fire hose support during earthquakes, enhancing its stability and thus providing seismic resistance. It also ensures structural integrity during earthquakes, preventing damage and allowing for timely firefighting. The silicone shock-absorbing ring, combined with a dust cover, provides both seismic resistance and dust protection, as well as physical protection.

[0020] This invention enables the rapid and smooth deployment of the fire hose through the sliding adjustment of the hose hanger, allowing the fire hose to be pulled out at any angle within a 180-degree arc. The hose hanger in the fire hose bracket can control the fire hose to keep the water within the first three folds of the hose without leakage after water is supplied and before the fire hose is withdrawn for use.

[0026] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0027] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses a fire hose support for a nuclear power plant, such as... Figure 1 As shown, the device includes a mounting base 2, a support body 1, and a clamp 3. The support body 1 is installed at one end of the mounting base 2, and the clamp 3 is installed at one end of the support body 1. A shock-absorbing ring is installed at the connection position between one end of the support body 1 and the mounting base 2. The clamp 3 includes a clamp 31, a pin 32, and a fixing plate. The clamp 31 is fitted onto the fire hose, and the pin 32 is installed at one end of the clamp 31. An elastic buffer pad is installed on the inner side of the clamp 31.

[0028] Specifically, the fire hose is installed by mounting the fixing base 2, the bracket body 1, and the clamp 3. There is no need to set up a large fire box. The fire hose can be placed on the bracket body 1 and the fire nozzle can be installed on the clamp 3. When not in use, the fire nozzle is fixed and fixed to the wall or steel structure by mounting the fixing base 2. This allows for the arrangement in small areas, saving space and making it convenient to access.

[0029] By installing a silicone damping ring between one end of the support body 1 and the mounting base 2, the seismic resistance of the fire hose support is effectively improved. This ensures the normal operation of the fire hose support during earthquakes, enhancing its stability and thus providing seismic resistance. The structure remains intact during earthquakes, preventing damage and allowing for timely firefighting. The silicone damping ring, combined with the dust cover 15, provides both seismic resistance and dust protection, as well as physical protection.

[0030] Specifically, the silicone shock-absorbing rings are combined with the dust cover 15 to provide earthquake resistance, dust protection, and physical protection. The silicone shock-absorbing rings effectively absorb and disperse vibration energy, reducing the transmission of vibration between objects. During an earthquake, this reduces the impact of vibration on surrounding structures, protects the various components of the fire hose support, extends its service life, and prevents damage or collapse, ensuring the fire hose support can still be used normally after an earthquake.

[0031] The dust cover 15 serves a basic dust protection function, and also protects water hoses in scenarios such as earthquakes.

[0032] The main body of the support frame 1 includes a support shell 11, a support rod 12, a support platform 13, a hose hanging rod 14, and a dust cover 15. The dust cover 15 is installed at the lower end of the support shell 11. One end of the support shell 11 is rotatably connected to the mounting base 2, and the other end of the support shell 11 is connected to the fixing plate.

[0033] Specifically, the hose hanger 14 allows for rapid and smooth deployment of the hose through sliding adjustment. The axial hole between the mounting base 2 and the main body 1 enables 180° rotation, allowing the fire hose to be pulled out at any angle within the 180-degree arc. The hose hanger 14 in the fire hose bracket ensures that, after the fire hose is connected to water but before it is withdrawn for use, the water level in the fire hose is maintained within the first three folds of the hose, preventing leakage.

[0034] like Figure 2 As shown, a support rod 12 is installed at one end of the support housing 11, and a support platform 13 is installed at the other end of the support housing 11. A plurality of hose hanging rods 14 are spaced apart between the support rod 12 and the support platform 13, and these hose hanging rods 14 are arranged along the length of the support housing 11. One end of each hose hanging rod 14 is movably connected to the support rod 12, and the other end rests on the support platform 13.

[0035] One end of the hose hook 14 is looped through the support rod, and the other end rests on the support platform 13. When the hose is pulled outward, the hose hook 14 slides along the support rod 12. When the end of the hose hook 14 rests on the support platform 13, it slides outward to the end of the support platform 13 and then falls down, causing the hose hanging on the hose hook 14 to fall off. Since the hose is hung on the hose hook 14 in sections, the hose hook 14 will only move when the corresponding hoses are pulled in sequence.

[0036] When the water source is turned on, and the hose is not in use, it hangs on all hose hangers 14. The hose is kept within the first three folds of the hose to prevent leakage, ensuring that water is contained within the hose's initial flow range before it is withdrawn for use. In use, the end of the hose closest to the fire nozzle is pulled outwards, causing the hose hanger 14 closest to the fire nozzle to move towards the nozzle. This increases the distance between adjacent hose hangers 14, flattening the hose sections hanging on them and facilitating further outward pulling until the hose hanger 14 furthest from the fire nozzle moves closer to it, fully extending the hose. The entire process is convenient and quick, allowing for rapid deployment in fire situations.

[0037] A water hose is installed on the hose hanger 14, with one end of the hose connected to a fire hose nozzle. Specifically, the water hose is hung on the hose hanger 14, and one end of the hose is connected to the fire hose nozzle. In use, water passes through the hose and is then sprayed through the fire hose nozzle to the location of the fire for extinguishing.

[0038] The end of the pin 32 and the clamp 31 are connected by a chain 33. One end of the chain 33 is connected to the clamp 31, and the other end is connected to the bracket body 1. Specifically, the pin 32 and the clamp 31 are connected by the chain 33. When the pin 32 is removed, its position can be fixed by the chain 33 to prevent it from being lost. This allows the pin 32 to be quickly installed on the clamp 31 when needed. In the locked state, the pin 32 and the clamp 31 form a space that can hold the fire hose. This ensures that the fire hose is fixed to the fire hose bracket and will not fall off during an earthquake.

[0039] By using the clamp 31 in conjunction with the pin 32, the fire hose can be easily removed from the clamp 31 by simply removing the pin 32 when needed. When not in use, the pin 32 also ensures that the fire hose is stably installed inside the clamp 31.

[0040] Pin 32 is a D-type pin. Specifically, a D-type pin has a flat surface and an arc-shaped surface. The flat surface is used for positioning and preventing rotation, while the arc-shaped surface mates with the mounting hole to provide better centering accuracy.

[0041] The contact surface between the elastic buffer pad and the fire hose nozzle is provided with anti-slip texture. Specifically, the inner side of the clamp 31 is provided with an elastic buffer pad, and the contact surface between the elastic buffer pad and the fire hose nozzle is provided with anti-slip texture. By setting the elastic buffer pad with anti-slip texture, the fire hose nozzle is stably installed inside the clamp 31.

[0042] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
