DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0021] An embodiment of the utility model, as Figure 1 and Figure 2 As shown, connecting flanges 11 are provided at both ends of the monitoring tube body 1, which are connected to other tube bodies. A positioning table 12 protruding outward is provided on the surface of the monitoring tube body 1, and a detector body 2 is fixedly installed on the positioning table 12. The detector body 2 includes a fixed shell 21 installed on the positioning table 12 and a probe 23 passing through the positioning table 12 and arranged inside the monitoring tube body 1. The probe 23 is connected to the fixed shell 21 through an angle adjustment mechanism 22. An extinguishing device 3 is provided on the side of the monitoring tube body 1 opposite to the detector body 2. The extinguishing device 3 includes an infusion pipeline connected to the monitoring tube body 1, a controller is connected to the bottom of the infusion pipeline, and the probe 23 is connected to the controller through a wireless transmission module. When in use, the servo motor 24 drives the rotating shaft 223 to rotate through the gear transmission mechanism, thereby driving the probe 23 to rotate in a circle. Once a spark appears, the temperature sensor 231 located at the top of the probe 23 will receive the temperature data and remotely transmit it to the extinguishing device 3. The movably installed probe 23 improves the detection range of sparks in the pipeline.

[0022] A central hole 121 penetrating the positioning table 12 and the wall of the monitoring tube body 1 is provided at the center of the positioning table 12 , and threaded fixing holes 122 are symmetrically distributed on both sides of the central hole 121 , which facilitates the positioning and installation of the detector body 2 .

[0023] A positioning hole corresponding to the position of the threaded fixing hole 122 is provided on the fixed shell 21. A slot 213 with a depth less than the thickness of the fixed shell 21 is opened at the position corresponding to the positioning hole of the fixed shell 21 to facilitate the positioning and locking of the fixing bolt. A rectangular mounting groove 211 is opened on one side of the fixed shell 21 close to the monitoring tube body 1.

[0024] A connecting rod 221 is arranged in the rectangular mounting groove 211, and the end of the connecting rod 221 is connected to the angle adjustment mechanism 22. A servo motor 24 is installed on the side of the fixed shell 21 away from the monitoring tube body 1. As a preferred embodiment of the present application, the length of the connecting rod 221 is adjustable to adapt to the detection tube body 1 with different wall thicknesses. By extending the length of the connecting rod 221, the rotatable range of the probe 23 is increased accordingly, thereby avoiding collision and damage between the probe 23 and the monitoring tube body 1 during rotation.

[0025] The angle adjustment mechanism 22 includes a clamping plate 222 symmetrically distributed and fixed at the end of a connecting rod 221. A rotating hole is opened in the center of the clamping plate 222. A rotating shaft 223 is inserted and installed in the rotating hole. A probe 23 arranged between the two clamping plates 222 is installed on the rotating shaft 223. The probe 23 is fixed on the rotating shaft 223. When the rotating shaft 223 rotates, the probe 23 is driven to rotate synchronously, thereby increasing the detection range of the probe 23.

[0026] A temperature sensor 231 is installed on the side of the probe 23 away from the angle adjustment mechanism 22. Once a spark appears, the temperature sensor 231 located on the top of the probe 23 will receive the temperature data and remotely transmit it to the extinguishing device 3 to perform fire extinguishing operations on the monitoring pipe body 1.

[0027] A driven gear 224 is provided at the end of the rotating shaft 223, and a driving gear 225 meshingly connected to the driven gear 224 is provided in the rectangular mounting groove 211. The driving gear 225 is powered by the servo motor 24, and the output end of the servo motor 24 is connected to the driving gear 225. When the driving gear 225 rotates along the servo motor 24, the driving gear 225 meshes with the driven gear 224 for transmission, so that the rotating shaft 223 drives the probe 23 to rotate in a circular direction, and the rotation direction of the probe 23 is changed according to the forward and reverse rotation of the servo motor 24.

[0028] An annular sealing rubber ring 212 is bonded and installed on the periphery of the rectangular installation groove 211 . After the detector body 2 is fixed on the positioning table 12 by bolts, the sealing rubber ring 212 is squeezed and deformed to play a sealing role, thereby ensuring the sealing requirements of the monitoring tube body 1 .
