Description

Technical Field

[0001] This utility model relates to the technical field of water testing devices, specifically a water testing device for a fire sprinkler system. Background Technology

[0002] Fire sprinkler system testing devices are important tools in fire protection testing. Their main purpose is to ensure the reliability and effectiveness of the sprinkler system. By simulating sprinkler conditions, the testing device can verify the system's response capability in the event of an actual fire, and promptly identify and resolve potential problems such as insufficient water pressure, pipe blockage, or damaged sprinkler heads. This not only helps protect the safety of people and property, but also meets the requirements of fire safety codes and standards, providing strong support for the fire safety of buildings.

[0003] While water testing devices can improve the testing efficiency of fire sprinkler systems, they still have certain problems: 1) During fire sprinkler testing, the area will be wetted by fire water, resulting in significant cleaning pressure later; 2) They cannot accurately detect the coverage area of ​​the sprinkler water, the water volume in each area under the coverage area, and other data; 3) The testing efficiency is low. Therefore, in view of the above situation, it is urgent to develop a water testing device for fire sprinkler systems to overcome the shortcomings in current practical applications and meet current needs.

[0020] Example:

[0021] Please see Figures 1-3 This utility model provides a technical solution: a fire sprinkler system test device, including a mobile platform 100, a test component 200 installed on the mobile platform 100 for testing the fire sprinkler system, and a drive component 300 installed on the mobile platform 100 for driving the test component 200 to rise and fall.

[0022] The detection assembly 200 includes a water collection hopper 210, a sliding shaft 220, a suspension 230, a water outlet 240, a hose 250, a measuring cylinder 260, a conduit 270, and a water storage tank 280. Multiple sliding shafts 220 are installed on the moving platform 100. The water collection hopper 210 is fixed to the top of the sliding shaft 220. Multiple water outlets 240 are fixed to the moving platform 100 through the suspension 230. The water outlets 240 are connected to and fixed to the water collection hopper 210 through the hose 250. Multiple measuring cylinders 260 are fixed to the moving platform 100. The water outlets 240 are located directly above the measuring cylinders 260. The water storage tank 280 is fixed inside the moving platform 100. The water storage tank and the measuring cylinders 260 are connected through the conduit 270.

[0023] Preferably, the water collection hopper 210 has multiple annular troughs 211, and each trough 211 has a drain outlet 212 installed at its bottom. The drain outlet 212 is connected to and fixed to the water inlet end of the hose 250. The number of drain outlets 212 and water outlets 240 are the same and correspond one-to-one. The number of water outlets 240 and measuring cylinders 260 are the same and correspond one-to-one. Specifically, the annular troughs 211 can independently collect water from different areas sprayed by the same fire sprinkler head during the test of the fire sprinkler system, so as to test whether the water pressure, water coverage area and regional water volume meet the standards.

[0024] Preferably, the water collection hopper 210 is inverted conical in shape, specifically, its structure facilitates the collection and measurement of fire sprinkler water.

[0025] Preferably, a valve 271 is installed between the bottom end of the conduit 270 and the water storage tank 280, and a water collection tank 272 is installed between the top end of the conduit 270 and the measuring cylinder 260. Specifically, the valve 271 can control whether the water in the measuring cylinder 260 enters the water storage tank 280, and a one-way valve is installed between each measuring cylinder 260 and the water collection tank 272.

[0026] Preferably, the drive assembly 300 includes a base frame 310, a rack 320, a motor 330, and a transmission gearbox 340. The top four corners of the base frame 310 are fixedly connected to the bottom ends of the sliding shafts 220. The motor 330 and the transmission gearbox 340 are both fixed on the moving platform 100. The transmission gearbox 340 is driven by the motor 330. The rack 320 is fixed on the top edge of the base frame 310. The top end of the rack 320 passes through the transmission gearbox 340 and the moving platform 100 in sequence, and the rack 320 is driven by the transmission gearbox 340. Specifically, the rack 320, in conjunction with the base frame 310, drives multiple sliding shafts 220 to rise and fall synchronously, thereby controlling the height adjustment of the water collection hopper 210.

[0027] Working principle: When the fire sprinkler system on the ceiling needs to be inspected, the movable platform 100 is pushed to the area below the fire sprinkler head. The height of the water collection hopper 210 of the detection component 200 is raised by the drive component 300. After adjustment, the fire sprinkler head is triggered, and fire water is sprayed out through the fire sprinkler head to form a circular coverage area. The fire water will fall into the water collection hopper 210 below. The annular trough 211 in the water collection hopper 210 divides the water collection hopper 210 into multiple independent fire water collection areas. The fire water falling into the area between two adjacent troughs 211 in the water collection hopper 210 will flow downward and converge into the lower trough 211. Then, it will be discharged through the drain outlet 212 and hose 250 connected below the trough 211. Water is introduced into a separate measuring cylinder 260 through the outlet 240. By observing the water level in each measuring cylinder 260, the spray range and water cooling are judged to determine whether they are qualified, thus realizing the measurement of fire water consumption in an independent area. After the measurement of a single fire sprinkler head is completed, the valve 271 is opened, and the fire water in the measuring cylinder 260 is introduced into the water storage tank 280 through the water collection tank 272 and the conduit 270. After the measuring cylinder 260 is emptied, the valve 271 is closed, and finally it is pushed to the bottom of the next fire sprinkler head. The above steps are repeated to perform fire testing. It should be noted that when adjusting the height, the motor 330 of the drive component 300, together with the transmission gearbox 340, drives the rack 320 to rise, and then drives the sliding shaft 220 and the water collection hopper 210 to rise through the bottom frame 310, thereby realizing the height adjustment.
