Description

Technical Field

[0001] The utility model relates to the technical field of fire detection, in particular to a detection device for the strength of a fire sprinkler head. Background Art

[0002] A fire sprinkler head is a water spraying device used in a fire sprinkler system. When a fire occurs, water is sprayed out through the sprinkler head splash plate to extinguish the fire.

[0003] Traditional fire sprinkler head strength testing devices have complex structures, cumbersome operations, and low testing efficiency. They are unable to perform strength testing on multiple fire sprinkler heads simultaneously, and are unable to observe the water spraying conditions of the fire sprinkler heads, resulting in inaccurate test results. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art that it is impossible to simultaneously test the strength of multiple fire sprinkler heads and it is impossible to observe the water spraying conditions of the fire sprinkler heads, resulting in inaccurate test results. A detection device for the strength of fire sprinkler heads is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A device for detecting the strength of a fire sprinkler head comprises a U-shaped frame, wherein a water tank for storing water is provided in the U-shaped frame;

[0007] Wherein, a fixed inverted U frame is fixed at the top of the U-shaped frame, a movable inverted U frame slides inside the fixed inverted U frame, a fixed pipe is fixed inside the movable inverted U frame, the bottom end of the fixed pipe is fixedly connected with a connecting pipe for installing a fire sprinkler head body, the surface of the fixed pipe is fixedly connected with a connecting pipe, a manual pressure pump is provided at the top of the U-shaped frame, the water outlet of the manual pressure pump is fixedly connected with the connecting pipe, the water inlet of the manual pressure pump is connected with a water tank, and the surface of the connecting pipe is fixedly connected with a pressure gauge for pressure measurement;

[0008] A shielding portion is provided in the U-shaped frame, and the shielding portion includes two side baffles fixed in the U-shaped frame. A group of lifting components is provided in the fixed inverted U frame, and the lifting components are used to send the fire sprinkler head body between the two side baffles.

[0009] In a possible design, a plurality of the connecting pipes are provided, and the plurality of connecting pipes are evenly arranged on the surface of the fixed pipe.

[0010] In a possible design, a plurality of the connecting pipes are threadedly connected with detachable sealing plugs.

[0011] In a possible design, both side panels are made of transparent glass.

[0012] In one possible design, the lifting assembly includes a first groove opened in the fixed inverted U frame, two threaded blocks slide in the first groove, a bidirectional screw rod rotates in the first groove, the two threaded blocks are respectively threadedly connected to the positive and negative thread segments on the circumferential surface of the bidirectional screw rod, the side ends of the bidirectional screw rod move outward to penetrate the fixed inverted U frame and are fixed with a turning handle, the bottom ends of the two threaded blocks are rotated with support rods, and the two support rods are rotated on the top of the movable inverted U frame.

[0013] In a possible design, a filter plate is fixed in the water tank.

[0014] In this application, according to the number of fire sprinkler head bodies that need to be tested, the same number of sealing plugs are screwed down, and the fire sprinkler head bodies are fixed into the connecting pipes in turn. The bidirectional screw rod is driven to rotate by turning the handle, and the rotation of the bidirectional screw rod drives the two threaded blocks to move in opposite directions. The two threaded blocks respectively drive the side ends of the two support rods to move in opposite directions, thereby driving the movable inverted U-frame to move downward relative to each other, and the fire sprinkler head body is moved between the two side baffles. Subsequently, the initial test pressure is slowly pressurized to 1.5 times by starting the manual pressure pump. Rated pressure, maintain pressure for 20 seconds, check for water leakage. If the initial test is passed, continue to increase the pressure to 2.5 times the rated pressure, maintain the pressure for 10 minutes, and check for water leakage. After the static stability test is passed, slowly increase the pressure to 3 times the rated pressure, observe the pressure gauge through the pointer to check for water leakage, and pay attention to observe whether the fire sprinkler head has deformation, discoloration and other abnormal conditions. Restore the pressure to 1.5 times the rated pressure before the test, maintain it for 20 seconds without water leakage. After the above test is passed, quickly increase the pressure to 4 times the rated pressure, and maintain it for 5 minutes without water leakage;

[0015] If leakage occurs, the water will be blocked by the two side baffles and flow back into the water tank, realizing water recycling.

[0016] Beneficial effect: In the utility model, the detection device for the strength of a fire sprinkler head can conveniently send the fire sprinkler head body into the detection area through the coordinated arrangement of a manual pressure pump, a connecting pipe, a connecting pipe, a pressure gauge, a fixed pipe, a movable inverted U frame and a lifting assembly, and the water in the water tank is sent into the fire sprinkler head body through the manual pressure pump. The pressure value at the fire sprinkler head body can be detected by the pressure gauge, so as to judge whether the strength of the fire sprinkler head is qualified. The utility model has a simple structure, is easy to operate, and improves the detection efficiency.

[0017] In the present invention, the fire sprinkler head strength detection device can detect multiple fire sprinkler head bodies at one time by providing multiple connecting pipes and sealing plugs, thereby further improving the detection efficiency. At the same time, the sealing plug can seal the unused connecting pipes to prevent water from flowing out.

[0018] In the utility model, the side baffle made of transparent glass is provided, so that the water spraying condition of the fire sprinkler head body can be easily observed, thereby judging whether the water spraying effect of the fire sprinkler head is qualified, thereby improving the accuracy of detection.
