Description

Technical Field

[0001] The utility model relates to an installation method of internal sprinkler in a downflow-upfeed shelf, which is mainly applicable to the installation of the internal sprinkler system in the high-bay stereoscopic warehouse shelf within the scope of industrial engineering, and belongs to the technical field of indoor fire protection engineering. Background Art

[0002] The internal sprinkler system in the shelf is an important fire extinguishing and protection system, mainly used to prevent the goods and shelves in the warehouse from being damaged in a fire. The system consists of a series of valve accessories, sprinkler heads and water pipes, and uses water or other fire extinguishing agents to control the fire. Its working principle is that when the temperature reaches a specific threshold value, the fusible alloy breaks, and the water pressurized by the pressure pipe will be ejected. The water flow spreads out under the action of the top metal sheet, thereby controlling the fire situation.

[0003] For the installation method of the internal sprinkler in the branch-shaped shelf, the upflow-downfeed type is mostly adopted both at home and abroad. The load of the sprinkler main pipe and the branch riser is borne by hanging on the light steel roof and attaching to the shelf. The overall structure is top-heavy, which increases the load-bearing requirements and safety risks of the building main body and the shelf structure.

[0004] The conventional devices for internal sprinkler in the shelf have the following problems:

[0005] 1. Since the sprinkler main pipe is hung under the light steel roof, and the load-bearing capacity of the conventional light steel roof is limited, higher requirements are put forward for the building main body itself. During the installation process, the load of the sprinkler main pipe needs to be considered, thus increasing the project cost.

[0006] 2. Since the sprinkler main pipe is hung under the light steel roof and the sprinkler main pipe itself is relatively heavy, higher requirements are put forward for the supports and hangers of the sprinkler main pipe. It is necessary to consider the sway of the sprinkler main pipe during the use in case of a fire, thus increasing the potential safety hazard.

[0007] 3. Since the sprinkler main pipe is hung under the light steel roof, there is a large amount of high-altitude work, and the dense shelf main body makes the installation space cramped, and the installation is inconvenient, thus slowing down the project progress.

[0008] 4. Since the sprinkler branch riser is attached to the shelf column, in the actual process, the conventional shelf products do not consider the load of the sprinkler branch riser attachment. Therefore, higher requirements are put forward for the shelf main body itself. During the installation process, the load of the sprinkler branch riser needs to be considered, thus increasing the cost of the shelf.

[0009] 5. Since the sprinkler branch riser is attached to the shelf column, during the use process, the shelf is deformed due to force over time, thus increasing the potential safety hazard. Summary of the Invention

[0010] The technical problem to be solved by the utility model is to provide a spray installation device suitable for high-rise warehouse shelves within the scope of industrial engineering, which greatly reduces the amount of high-altitude installation work, reduces the project cost, speeds up the project progress, and ensures construction safety.

[0011] In order to solve the above technical problems, the technical solution of the utility model is: a downward-feeding spray device in the shelf, which includes a spray horizontal main pipe located at the bottom of the shelf, the starting end of the spray horizontal main pipe is connected to the spray main pipe, and the end is provided with a drain valve for system maintenance, and the spray horizontal main pipe is connected to a plurality of vertically arranged variable-diameter spray branch pipes, the bottom end of the variable-diameter spray branch pipe is the starting end connected to the spray horizontal main pipe, and the top end of the variable-diameter spray branch pipe is the end connected to the exhaust horizontal pipe, the starting end of the exhaust horizontal pipe is provided with an automatic exhaust valve, and the end is connected to the water testing device.

[0012] Preferably, the bottom ends of the spray horizontal main pipe and the variable-diameter spray support pipe are fixedly supported on the ground through channel steel supports.

[0013] Preferably, a signal valve and a water flow indicator are provided at the starting end of the spray horizontal main pipe.

[0014] Preferably, the automatic exhaust valve is located at the highest point of the system to discharge gas accumulated in the system.

[0015] The sprinkler horizontal main pipe is connected to the ground via a fixedly supported channel steel support, so that the load of the sprinkler main pipe is transferred to the ground, reducing the load-bearing requirements for the building main body.

[0016] The bottom end of each variable diameter sprinkler support pipe is provided with a channel steel support fixed to the ground, so that most of the load of the variable diameter sprinkler support pipe is transferred to the ground, reducing the load-bearing requirements for the shelf body.

[0017] The various components of the sprinkler system can be selected based on the relevant products currently available on the market. Except for specific engineering projects that have special pipe material requirements, conventional pipes are made of hot-dip galvanized steel pipes inside and outside.

[0018] When the load on the sprinkler main pipe is large and the conventional light steel roof has limited load-bearing capacity, the utility model can position the ground-fixed channel steel support directly below the sprinkler support riser corresponding to the sprinkler horizontal main pipe, thereby transferring most of the load of the sprinkler main pipe and the support riser to the ground, reducing the requirements for the building main body.

[0019] When the shaking of the sprinkler main pipe needs to be considered during use due to a fire, and higher requirements are placed on the sprinkler main pipe support and hanger brackets themselves, the utility model can reduce the use of high-altitude support and hanger brackets, thereby reducing the safety hazards of pipeline shaking.

[0020] When the sprinkler main pipe is hung under the light steel roof, with a large amount of high-altitude work, a dense main body of the shelf, and a cramped installation space, the utility model can effectively reduce the amount of high-altitude work and speed up the project progress.

[0021] When the sprinkler branch risers are laid on the shelf columns and the shelf products do not consider all the loads of the sprinkler branch risers, resulting in the deformation of the shelf due to stress over time, the utility model can transfer most of the loads of the branch risers to the ground through the channel steel supports, greatly reducing the bearing requirements for the main body of the shelf and reducing the potential safety hazard of shelf deformation.

[0022] The channel steel supports for ground fixing and supporting of the utility model are arranged directly below the corresponding sprinkler branch risers of the sprinkler horizontal main pipe, so that most of the loads of the sprinkler main pipe and branch risers are transferred to the ground. The diameters of the sprinkler branch risers gradually decrease from bottom to top. The sprinkler branch risers with larger diameters are installed at lower positions. Each top end of the sprinkler branch risers is connected to the exhaust horizontal pipe and an automatic exhaust valve is set at the highest position. These measures and methods can significantly reduce the amount of high-altitude installation work, reduce the project cost, speed up the project progress, and ensure construction safety and many other advantages. Brief Description of the Drawings

[0023] Figure 1 It is a schematic diagram of the downward-feed and upward-supply sprinkler device in the shelf provided by the utility model. Detailed Embodiment

[0024] To make the utility model more obvious and understandable, a preferred embodiment is described in detail below in conjunction with the attached drawings.

[0025] Embodiment

[0026] As Figure 1 shown, it is a downward-feed and upward-supply sprinkler device in the shelf provided by the utility model, which includes a sprinkler horizontal main pipe 5 located at the bottom inside the shelf. The starting end of the sprinkler horizontal main pipe 5 is connected to the sprinkler main pipe, and a drain valve 6 for system maintenance is provided at the end. A plurality of vertically arranged stepped sprinkler branch risers 7 are connected to the sprinkler horizontal main pipe 5. The bottom end of the stepped sprinkler branch riser 7 is the starting end and is connected to the sprinkler horizontal main pipe 5. The top end of the stepped sprinkler branch riser 7 is the end and is connected to the exhaust horizontal pipe 9. An automatic exhaust valve 3 is provided at the starting end of the exhaust horizontal pipe 9, and the end is connected to a test water device 8.

[0027] The bottom ends of the sprinkler horizontal main pipe 5 and the stepped sprinkler branch risers 7 are fixedly supported on the ground through channel steel supports 4.

[0028] A signal valve 1 and a water flow indicator 2 are provided at the starting end of the sprinkler horizontal main pipe 5, and the elevation can be adjusted according to the requirements of the actual engineering project. The connection point of the end test water device 8 is located at the most unfavorable point end of the sprinkler system inside the shelf, and the elevation of the end test water device 8 can be adjusted according to the requirements of the actual engineering project.

[0029] The automatic exhaust valve 3 is located at the highest point of the system to exhaust the gas accumulated in the system.

[0030] The difference between the present utility model and the conventional in-rack sprinkler device lies in:

[0031] 1) When the load of the sprinkler main pipe is large and the load-bearing capacity of the conventional light steel roof is limited, a downward-feed and upward-supply in-rack sprinkler installation method can set the channel steel supports fixed on the ground directly below the sprinkler branch risers corresponding to the sprinkler main horizontal pipe, so that most of the loads of the sprinkler main pipe and branch risers are transferred to the ground, reducing the load-bearing requirements for the building main body.

[0032] 2) When it is necessary to consider the sway of the sprinkler main pipe during the use process due to a fire, which poses higher requirements for the supports and hangers of the sprinkler main pipe, a downward-feed and upward-supply in-rack sprinkler installation method can reduce the use of high-altitude supports and hangers, reducing the potential safety hazard of sway.

[0033] 3) When the sprinkler main pipe is hung under the light steel roof, with a large amount of high-altitude work, a dense rack main body and a cramped installation space, a downward-feed and upward-supply in-rack sprinkler installation method can effectively reduce the amount of high-altitude work and speed up the project progress.

[0034] 4) When the sprinkler branch risers are laid on the rack columns, resulting in the deformation of the rack due to force over time, a downward-feed and upward-supply in-rack sprinkler installation method can transfer most of the loads of the branch risers to the ground through the channel steel supports, greatly reducing the load requirements for the rack main body and reducing the potential safety hazard of rack deformation.

[0035] During the implementation of this downward-feed and upward-supply in-rack sprinkler device, the system components are selected according to the design drawings and existing related products in the market. Except for special pipeline material requirements in specific engineering projects, the conventional pipelines are made of internally and externally hot-dip galvanized steel pipes. The connection work of each part of the components can be assembled and installed on-site, and finally combined into a downward-feed and upward-supply in-rack sprinkler installation method.

[0036] The technical solution provided by the utility model is applicable to the situation where the load of the sprinkler main pipe is large, the load-bearing capacity of the conventional light steel roof is limited, the amount of high-altitude operation is large, the main body of the shelf is dense, the installation space is cramped, and the swaying of the sprinkler main pipe needs to be considered during the use in case of fire. When the sprinkler branch riser is attached to the shelf column and the shelf is deformed due to force over time, it is about how to transfer most of the loads of the sprinkler main pipe and the branch riser to the ground, reduce the bearing requirement for the building main body, reduce the use of high-altitude supports and hangers, reduce the safety hazard of swaying, reduce the amount of high-altitude operation, and transfer most of the loads of the branch riser to the ground through the channel steel support, greatly reducing the bearing requirement for the main body of the shelf. This installation method of the downward-flow and upward-supply sprinkler in the shelf has the advantages of accelerating the installation project progress, wide application scenarios, safe and reliable use, and reasonable structure.
