[0003] Traditional methods for detecting fire smoke detectors mostly use manual hand-held electronic smoke generators for smoke tests. This method has problems such as cumbersome operation, low efficiency, and large influence of human factors on detection accuracy. At the same time, it is difficult to access high-altitude areas such as building roofs, making the detection work more difficult. Therefore, we have proposed a building fire detection device.

Detailed implementation manner
[0019] Embodiment 1
[0020] As Figures 1 to 4As shown in the figure, the utility model discloses a building fire detection device. The adopted technical solution is as follows: it includes a fixed cylinder 1, a rotating cylinder 2, a lifting assembly 4 and a lifting platform 6. The bottom of the fixed cylinder 1 is provided with a rotating cylinder 2, and the rotating ring 14 arranged at the top of the rotating cylinder 2 is rotationally connected with the annular groove arranged at the inner bottom of the fixed cylinder 1. Anti-slip vertical grooves 12 are arranged at equal intervals in a circumferential array on the outer side of the rotating cylinder 2. The anti-slip vertical grooves 12 can increase the friction between the outer side of the rotating cylinder 2 and the user's hand. A lifting assembly 4 is arranged inside the fixed cylinder 1 and the rotating cylinder 2. The lifting assembly 4 is composed of a threaded rod 41, a guide rod 42 and a connecting piece 43. One end of the threaded rod 41 is fixedly installed at the center of the inner bottom of the rotating cylinder 2, and the other end of the threaded rod 41 is rotationally connected with the center of the inner top of the fixed cylinder 1 through a bearing. A connecting piece 43 is threadedly installed on the threaded rod 41. Guide rods 42 are respectively arranged at the front and rear ends of the top of the connecting piece 43. The other ends of the guide rods 42 respectively pass through the sliding holes 16 arranged at the top of the fixed cylinder 1 and are fixedly connected with the lifting platform 6 arranged above the top of the fixed cylinder 1. By rotating the rotating cylinder 2, the rotating ring 14 at the top of the rotating cylinder 2 rotates in the annular groove at the inner bottom of the fixed cylinder 1. At the same time, the rotating cylinder 2 will drive the threaded rod 41 to rotate together during the rotation process. The top of the threaded rod 41 is rotationally connected with the center of the inner top of the fixed cylinder 1 through a bearing. Therefore, during the rotation process of the threaded rod 41, it drives the connecting piece 43 to drive the guide rod 42 to slide along the sliding hole 16, so that the guide rod 42 drives the lifting platform 6 to move, thereby adjusting the height position of the lifting platform 6. A threaded cylinder 7 is arranged at the center of the top of the lifting platform 6. An electronic smoke generator 8 is movably installed inside the threaded cylinder 7. And a fixing assembly 5 is arranged at the top of the threaded cylinder 7. The fixing assembly 5 is composed of a moving top ring 51, a clamping rod 52, a groove 53 and a pin 55. There are three grooves 53, and the grooves 53 are arranged at equal intervals in a circumferential array on the top of the threaded cylinder 7. Pins 55 are respectively arranged in the middle parts of the inner sides of the grooves 53. Clamping rods 52 are respectively rotationally installed in the middle parts of the pins 55. The inner bottom parts of the clamping rods 52 are respectively in movable contact with the top of the moving top ring 51 threadedly installed at the outer bottom of the threaded cylinder 7. By rotating the moving top ring 51, the moving top ring 51 pushes against the inner bottom of the clamping rod 52. Since the clamping rod 52 is rotationally connected with the pin 55 in the groove 53, this pushing action utilizes the lever principle to make the tops of the clamping rods 52 rotate inwards simultaneously, thereby clamping the outer side of the electronic smoke generator 8. Rubber blocks 54 are respectively arranged at the tops of the clamping rods 52. When the clamping rods 52 clamp the electronic smoke generator 8, the rubber blocks 54 can increase the friction at the top of the clamping rods 52 and prevent the clamping rods 52 from scratching the electronic smoke generator 8. It also includes a snap ring 9, a shoulder strap 10 and a pin 11. The snap ring 9 is rotationally installed in the card slot 15 arranged at the outer top of the fixed cylinder 1. One end of the snap ring 9 is fixedly installed with a shoulder strap 10. The through hole arranged at the other end of the shoulder strap 10 is rotationally connected with the pin 11 arranged at the center of the bottom of the rotating cylinder 2. By the snap ring 9 being rotationally installed in the card slot 15 on the outer side of the fixed cylinder 1,It is connected to the strap 10, and the other end of the strap 10 is connected to the bottom of the rotating cylinder 2 through a pin 11. This design allows the user to easily carry the fire detection device through the strap 10. It also includes a controller 3 and a mobile power supply 13. The mobile power supply 13 is fixedly installed at the center of the inner bottom of the lifting platform 6, and the controller 3 is arranged in the middle of the outer side of the fixed cylinder 1. The output end of the controller 3 is electrically connected to the input end of the electronic smoke generator 8, and the input end of the controller 3 is electrically connected to the output end of the mobile power supply 13. Through the setting of the controller 3, it is convenient for the user to control the electronic smoke generator 8, and the mobile power supply 13 provides power support for the electronic smoke generator 8. At the same time, the provision of the mobile power supply 13 enables the device to work without an external power supply, improving the independence and flexibility of the device.
[0021] The working principle of the present utility model: When detecting the fire smoke detector on the roof inside a building, first, install the electronic smoke generator 8 into the threaded cylinder 7, and then rotate the movable top ring 51 to push the inner bottom of the clamping rod 52. Since the clamping rod 52 is rotatably connected to the pin shaft 55 in the groove 53, this pushing action utilizes the lever principle to make the top of the clamping rod 52 rotate inward simultaneously, thereby clamping the outside of the electronic smoke generator 8. The rubber block 54 provided at the top of the clamping rod 52 not only increases the friction during clamping but also plays a role in protecting the electronic smoke generator 8, preventing scratches on it during the clamping process; Next, when the user needs to adjust the position of the electronic smoke generator 8 for fire detection at different heights, it can be achieved by rotating the rotating cylinder 2. When the rotating cylinder 2 is rotated by the user, the rotating ring 14 at the top of the rotating cylinder 2 rotates in the annular groove at the inner bottom of the fixed cylinder 1, and the anti-slip vertical grooves 12 provided on the outer side of the rotating cylinder 2 can increase the friction between the outer side of the rotating cylinder 2 and the user's hand, making the rotation operation more stable and reliable. During the rotation of the rotating cylinder 2, since the bottom of the rotating cylinder 2 is fixedly connected to the threaded rod 41, therefore, the rotating cylinder 2 will drive the threaded rod 41 to rotate together during the rotation process. The top of the threaded rod 41 is rotatably connected to the center of the inner top of the fixed cylinder 1 through a bearing. Thus, during the rotation of the threaded rod 41, it drives the connecting member 43 to drive the guide rod 42 to slide along the sliding hole 16, so that the guide rod 42 drives the lifting platform 6, the threaded cylinder 7, and the electronic smoke generator 8 to move together; After adjusting the electronic smoke generator 8 to the appropriate height, start the electronic smoke generator 8 through the controller 3, and the electronic smoke generator 8 starts to work, releasing smoke to simulate the fire scene environment to test the response of the fire smoke detector.
