Description

Technical Field

[0001] The utility model relates to the technical field of fire hydrants, in particular to a single-hydrant narrow combined fire hydrant device for an underground garage. Background Art

[0002] In the underground garage of commercial housing, in order to carry out fire protection maintenance on the garage, the fire hydrant is generally hung on the outside of the column through a bracket. This hanging method is similar to the current air conditioner outdoor unit.

[0003] The current installation method of fire hydrants occupies a part of the area of ​​the underground garage, which is an unreasonable use of value for real estate developers. Although the occupied area is only a small part, the location is on one side of the column. Whether it is next to the parking space or the road, it will affect the parking and passage of nearby vehicles. Therefore, real estate developers must avoid parking spaces and fire hydrants during installation to give the underground parking spaces a large enough area. This practice has resulted in the area of ​​the parking spaces in the underground garage being occupied by a part of the fire hydrants, reducing the developer's profit from the construction of the underground garage.

[0004] In addition, because the water inlet pipes of the current fire hydrants are on the left and right sides, when the fire hydrants are installed on the columns in the underground garage, the space around the columns will also be occupied, affecting the planning of nearby parking spaces. In addition, the current column size is between 550mm-600mm, while the current fire hydrant size that meets the national standard is 650mm-700mm. Due to the size problem, the current fire hydrants are also inconvenient to install, especially for columns smaller than 550mm*550mm. Utility Model Content

[0022] like Figure 1 As shown, a single-hydrant narrow combined fire hydrant equipment for underground garages includes a fire cabinet 1. The width of the fire hydrant is less than or equal to the width of the column. The fire cabinet is made into a non-standard size with a width of 650mm-700mm. The fire cabinet 1 is embedded in the lower part of the column of the underground garage. Compared with the current installation method, this installation structure does not occupy extra garage space. During implementation, the installation position of the fire hydrant equipment is reserved when the column is cast.

[0023] The fire cabinet 1 is provided with three cavities, including an upper placement cavity 2, a middle water receiving cavity 3, and a bottom placement cavity 4. The upper placement cavity 2 is mainly used to place water spray supplies, the bottom placement cavity 4 is mainly used to place fire extinguishing supplies, and the middle water receiving cavity 3 is mainly used to receive water and pass water. A water inlet pipe 11 is vertically installed on the top of the fire cabinet 1. The water inlet pipe 11 passes through the upper placement cavity 2 and then extends into the middle water receiving cavity 3, and is connected to the inlet of the valve 15 in the middle water receiving cavity 3. By inserting the water inlet pipe 11 from the top, the fire source can be extinguished by the deadweight of the fire water source. In addition, by installing the water inlet pipe 11 on the top, it is possible to avoid occupying the space at the bottom of the column, and it does not affect the parking of the vehicle, and there is no need to plan the parking space and improve the size of the column. A quick connector 14 and a branch pipe 16 are provided on the outside of the valve 15, which are used to connect a conventional fire hose with a large caliber, and to connect the branch pipe 16 to the spare water pipe in the underground garage.

[0024] When implementing, please refer to Figure 2 First, slots are made on the upper and lower frames of the upper layer of the cavity 2, and then the rubber sleeve 17 is installed in the circular slot, and then the water inlet pipe 11 is installed in the fire cabinet 1. The rubber sleeve 17 plays a role in preventing the pipe from being worn, and can also play a role in fixing the water inlet pipe 11 in the fire cabinet 1 by wrapping the water inlet pipe 11. The elbow part of the water inlet pipe 11 needs to be installed separately, which is a detachable part, and plays a convenient role in the installation in the fire cabinet 1.

[0025] When implementing the above solution, please refer to Figure 3 The middle water receiving chamber 3 is provided with a reel support 31, and a reel 32 is provided inside the reel support 31. The reel 32 is installed inside the reel support 31, which is an existing conventional facility. The reel 32 is rotatably connected to the inner wall of the middle water receiving chamber 3 through a rotating shaft 35. When in use, the reel 32 rotates itself to the outside of the fire cabinet 1 through the rotating shaft 35 to facilitate the arrangement of the branch water pipe 33.

[0026] A branch water pipe 33 is wrapped around the reel 32, one end of the branch water pipe 33 is connected to the branch pipe 16, and the other end of the branch water pipe 33 is connected to the branch nozzle 34. By connecting the branch water pipe 33 to the branch pipe 16, water is supplied uniformly, and then water is sprayed through the branch nozzle 34 to extinguish the fire. The branch pipe 16 and the branch nozzle 34 are all copper parts with a diameter of DN25, and the length of the branch water pipe 33 is L = 20-25 meters.

[0027] When implementing the above solution, please continue to refer to Figure 2A water hose 21 is placed in the upper placement chamber 2, one end of the water hose 21 is connected to a rotary joint 22 matching the quick joint 14, and one end of the water hose 21 is connected to a spray gun 23. By connecting the rotary joint 22 with the quick joint 14, water is uniformly supplied, and then water is sprayed through the spray gun 23 to extinguish the fire. The rotary joint 22 and the quick joint 14 are both made of steel-aluminum alloy, with a caliber of DN65, and the length of the water hose 21 is L=25 meters.

[0028] When implementing the above solution, please refer to Figure 4 A fire extinguisher 41 is vertically placed in the bottom placement cavity 4, and the fire extinguisher 41 can be directly lifted up to spray out the fire source. As a preferred solution, a positioning plate 42 is provided at the bottom of the bottom placement cavity 4. The positioning plate 42 is a circular structure, and the caliber of the positioning plate 42 should be larger than the caliber of the fire extinguisher 41, so that the circular fire extinguisher 41 can be placed inside. A magnet sheet 43 is placed at the bottom of the positioning plate 42. When the fire extinguisher 41 is placed, it will be adsorbed in the positioning plate 42. Since the fire cabinet 1 is generally made of iron, it will also be adsorbed by the magnet sheet 43, so as to facilitate the vertical state of the fire extinguisher 41 to be fixed, so as to avoid tipping over after being touched by humans, which will affect the fire extinguishing agent.

[0029] For the fire cabinet 1, during implementation, the outer side of the fire cabinet 1 is rotatably connected with a cabinet door 12, and the rotatable connection of the cabinet door 12 is generally connected by a hinge, and a push switch 13 is installed on the cabinet door 12, and the fire cabinet 1 can be opened by pressing the push switch 13. As a preferred solution, the cabinet door 12 is embedded in the cabinet body of the fire cabinet 1 and is flush with the front end of the fire cabinet 1, so that it will not protrude on the column, which is conducive to maintaining the flatness of the columns of the underground garage and will not have an adverse effect on the planning of the parking space.
