Description

Technical Field

[0001] The utility model relates to the technical field of fire detection, in particular to a novel building fire detection device. Background Art

[0002] Fire hydrants, formally called fire hydrants, are important urban infrastructure, firewalls that protect the lives of citizens, and are an important part of the city's water supply network. In order to ensure the effectiveness of fire hydrants, the water pressure of fire hydrants needs to be tested regularly.

[0003] Chinese patent CN215585354U discloses a novel building fire detection device, whose structure includes a body, a water storage tank, a storage box, a water inlet straight, a detection device, a water inlet valve, a first quick connector, a water tank cover, a storage box cover, a push handle, a plurality of rollers, a drainage valve, a water inlet pipe, a water flow pressure relief cotton and an external quick connection pipe. The water storage tank includes a first water tank, a second water tank and a third water tank. The external quick connection pipe includes a second quick connector, a third quick connector and a fire hose. The water storage tank is installed in the inner cavity at the lower end of the body. The water inlet straight is installed on the left top surface of the water tank cover. The bottom end of the detection device is threadedly connected to the top end of the water inlet straight. By providing a novel building fire detection device, a single fire hydrant can be effectively tested for water pressure, the effectiveness of the test can be guaranteed, and the water outlet pressure of each fire hydrant meets the standard requirements.

[0004] Commonly used building fire hydrants include indoor fire hydrants, outdoor fire hydrants and underground fire hydrants, and the diameters of the water outlets of different fire hydrants are also different. The diameters of the water outlets of common fire hydrants are DN50 (diameter 50mm), DN60 (diameter 60mm) and DN100 (diameter 100mm). The above patent only has a first quick connector of a fixed size connected to the fire hydrant, which results in that it can only detect fire hydrants of one size, but cannot detect fire hydrants of different models. Therefore, in view of the above situation, it is urgently necessary to develop a new type of building fire detection device that is easy to adjust and convenient for detecting fire hydrants of different models, so as to overcome the shortcomings in current practical applications and meet current needs.

[0021] See also Figure 1~Figure 4In an embodiment of the utility model, a novel building fire detection device comprises a temporary water storage tank 1, a rotating switching mechanism 2, a limiting mechanism 3, an adapter 4, a water pressure gauge 6, a connecting hose 7 and a conduit 8. A conduit 8 connected thereto is fixed on the top of the temporary water storage tank 1, and a water pressure gauge 6 is installed on the conduit 8. The temporary water storage tank 1 is rotatably connected with the rotating switching mechanism 2. The temporary water storage tank 1 is installed with a limiting mechanism 3 for limiting the rotation of the rotating switching mechanism 2. Three adapters 4 are installed on the rotating switching mechanism 2. The three adapters 4 are evenly distributed on the rotating switching mechanism 2. The diameters of the three adapters 4 are different so as to be connected to fire hydrants with different water outlet diameters. A connecting hose 7 is installed at the bottom of each of the three adapters 4. A threaded cap 701 is installed at the bottom of each connecting hose 7. The upper end of the conduit 8 is provided with a threaded cap connected to the threaded cap. 701 matches the external thread 801, and a drain outlet 101 is arranged at the lower left side of the temporary water storage tank 1.
