Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, specifically to a test device for building fire protection systems. Background Technology

[0002] Water testing of building fire protection systems is a crucial step in ensuring the normal operation of fire protection facilities. Currently, fire protection piping systems require regular water pressure and flow rate tests to verify their fire extinguishing effectiveness. Announcement No. CN21964401U discloses a water testing device for building fire protection systems, including a water tank and a detachable cover. A through groove is formed on the end face of the water tank, and a slidably connected filter screen is installed within this groove. A spline sleeve is rotatably nested at the center of the cover, and a matching spline shaft extends into the water tank. A connecting plate is located at the end of the spline shaft extending into the water tank, and a rotating shaft is connected through this connecting plate. A bushing is located at the bottom end of the rotating shaft, and a cleaning brush is located at one end of the bushing. A vertically movable motor is also located on the top surface of the cover corresponding to the spline shaft, and the motor output shaft is connected to the top surface of the spline shaft via a coupling. This invention not only effectively removes impurities from the filter screen surface but also allows the filter screen to be pulled out of the tank for thorough cleaning, thereby improving the efficiency of the device.

[0003] However, in actual use, since the length of the fixed pipe is fixed, in order to facilitate the connection between the fixed pipe and the fire pipe, a longer connecting pipe needs to be prepared to accommodate fire pipe interfaces in different locations. Therefore, after the inspection is completed, the connecting pipe needs to be stored. Because the connecting pipe is long, it is extremely inconvenient to store, and there will be residual water stains inside the connecting pipe. These water stains are easy to spill onto the ground and cause pollution to the ground environment.

[0004] Therefore, it is necessary to invent a water testing device for building fire protection systems to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a water testing device for building fire protection systems, in order to solve the problems in the technology of inconvenience in storing the connecting pipe and the easy spillage of water stains inside the connecting pipe onto the ground, causing pollution to the ground environment.

[0031] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0032] This utility model provides, for example Figures 1 to 2 The device shown is a water testing device for a building fire protection system. It includes a support frame 1. Fixed shafts 11 are fixedly connected to the left and right sides of the lower end of the support frame 1. Moving rollers 12 are rotatably connected to the front and rear ends of the fixed shafts 11. A water collection tank 2 is fixedly installed on the upper side of the support frame 1. A drain pipe 21 is fixedly connected to the side of the water collection tank 2 near the lower end. A first connector 22 is fixedly connected to the middle of the upper end of the water collection tank 2. A connecting component is provided on the upper side of the water collection tank 2. The connecting component includes a mounting base 3, an external threaded pipe 31, a sealing sleeve 32, a threaded sleeve 33, an anti-slip sleeve 34, a lifting pipe 4, a second connector 41, a connecting hose 5, and a third connector 51. The mounting base 3 is fixedly connected to the upper end of the water collection tank 2 near the left edge. An opening and closing valve 42 is fixedly installed on the surface of the lifting pipe 4. A pressure sensor 43 is fixedly installed inside the opening and closing valve 42.

[0033] During the water test, the testing device is moved to the vicinity of the monitoring point by the equipment bracket 1 and the moving roller 12. At this time, the connecting component is unfolded, the connecting hose 5 is connected to the interface on the surface of the fire pipe, and then the valve and the on / off valve 42 on the surface of the fire pipe are opened, so that the water flows into the interior of the water collection tank 2 through the riser pipe 4. During the water flow, the pressure sensor 43 detects the pressure of the water flow.

[0034] In addition, after the test is completed, the connecting component is put away, and the device is moved to the drain by the moving roller 12. The valve on the surface of the drain pipe 21 is opened to drain the water inside the water collection tank 2.

[0035] participate Figure 3 and Figure 4 The external threaded pipe 31 is fixedly connected to the upper end of the mounting base 3. The sealing sleeve 32 has an inverted trapezoidal cross section and is fixedly connected to the upper end of the external threaded pipe 31. The threaded sleeve 33 is threadedly connected to the surface of the external threaded pipe 31. An anti-slip sleeve 34 is fixedly connected to the surface of the threaded sleeve 33. The lifting pipe 4 is inserted into the interior of the external threaded pipe 31 and the sealing sleeve 32. The upper end of the lifting pipe 4 is fixedly connected to the second connector 41. Both ends of the connecting hose 5 are fixedly connected to the third connector 51. The third connector 51 on the right side is snapped and fixed to the second connector 41.

[0036] Specifically, during the unfolding of the connecting component, the threaded sleeve 33 is first rotated to the lowest end of the external threaded pipe 31. At this time, the lifting pipe 4 can slide up and down inside the external threaded pipe 31. After sliding the lifting pipe 4 to the optimal connection height, the threaded sleeve 33 is rotated upward. During the rotation, the upper end of the threaded sleeve 33 will gradually squeeze the sealing sleeve 32 inward, thereby locking and fixing the lifting pipe 4. The lifting pipe 4 is fixed at a suitable height. Then, the third connector 51 at the left end of the connecting hose 5 is connected to the connector on the surface of the fire pipe. Then, the water pressure inside the fire pipe is tested.

[0037] Meanwhile, after the inspection is completed, the threaded sleeve 33 is rotated downwards to unlock the lifting pipe 4. Then, the third connector 51 on the left side is separated from the connector on the surface of the fire pipe. At this time, the lower end of the lifting pipe 4 is completely retracted into the water collection tank 2. Then, the lifting pipe 4 is rotated 180° and the connecting hose 5 is rotated to the right side. At this time, the third connector 51 at the end of the connecting hose 5 away from the lifting pipe 4 is connected and fixed to the first connector 22. During the movement of the equipment, the water stains remaining inside the connecting hose 5 will slide along the first connector 22 into the water collection tank 2, preventing water from spilling onto the ground, improving the cleanliness of the ground environment, and further avoiding water waste.

[0038] The working principle of this utility model is as follows: By sliding the lifting pipe 4 up and down inside the external threaded pipe 31 and the sealing sleeve 32, the height of the lifting pipe 4 can be adjusted. Then, with the short connecting hose 5, the equipment can be connected to the fire pipeline. After the test is completed, the lifting pipe 4 is retracted into the water collection tank 2, which facilitates the movement and transportation of the equipment. Since the connecting hose 5 is short, it does not need to be folded and stored, which effectively improves the convenience of using the equipment and improves the efficiency of water testing. At the same time, after the test is completed, the third connector 51 on the left end of the connecting hose 5 is connected to the first connector 22. At this time, the water stains remaining inside the connecting hose 5 will be discharged into the water collection tank 2, preventing water stains from spilling onto the ground and causing pollution to the ground environment.
