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

[0021] like Figure 1 and Figure 2 As shown, the utility model provides a technical solution of a flange tee assembly, including a tee body 1, a docking flange 2 is provided on the tee body 1, a connecting through hole 3 is opened on the docking flange 2, a protective mechanism 4 is connected to the tee body 1, the protective mechanism 4 includes an upper protective cover 401 and a lower protective cover 404 connected to the tee body 1, and a mounting notch 407 is opened at the bottom of the lower protective cover 404. A heating mechanism 5 is provided between the upper protective cover 401 and the lower protective cover 404. Once ice is formed inside the tee body 1, the heating mechanism 5 can be activated. After the heating mechanism 5 is activated, it will heat the tee body 1, so that the temperature of the tee body 1 rises rapidly, melting the ice inside the tee body 1, ensuring that the liquid in the pipeline can flow normally, and the sealing cover 506 will be pressed tightly against the bottom of the power connector 502 to prevent water from entering the power connector 502.

[0022] like Figure 2 and Figure 3 As shown, the protective mechanism 4 includes an upper protective cover 401 and a lower protective cover 404 connected to the tee body 1, and the upper protective cover 401 and the lower protective cover 404 are both provided with a mounting groove 405, and a first sealing ring 406 is provided in the mounting groove 405. A mounting notch 407 is provided at the bottom of the lower protective cover 404, and docking holes 402 are provided at both ends of the upper protective cover 401 and the lower protective cover 404, and fixing bolts 403 are connected in the docking holes 402.

[0023] Specifically, after the upper protective cover 401 and the lower protective cover 404 are put on the outside of the induction heating coil 501, the fixing bolts 403 can be tightened. After tightening the fixing bolts 403, the upper protective cover 401 and the lower protective cover 404 can wrap the induction heating coil 501, reducing the contact between the induction heating coil 501 and the outside world, and extending the service life of the induction heating coil 501.

[0024] like Figure 2 and Figure 4 As shown, the heating mechanism 5 includes a power connector 502 fixedly mounted on the lower protective cover 404, an induction heating coil 501 fixedly mounted on the power connector 502, a tension spring 503 provided inside the power connector 502, a telescopic rod 505 movably mounted on the power connector 502, a sealing cover 506 fixedly mounted on the lower end of the telescopic rod 505, a second sealing ring 507 provided at the edge of the sealing cover 506, and a spring seat 504 fixedly mounted on the upper end of the telescopic rod 505.

[0025] Specifically, after the induction heating coil 501 starts working, it will heat the tee body 1, causing the temperature of the tee body 1 to rise rapidly, melting the ice inside the tee body 1, and ensuring that the liquid in the pipeline can flow normally. After the power cord is disconnected, the tension spring 503 will pull the telescopic rod 505 on the spring seat 504 to move upward, so that the sealing cover 506 is pressed against the bottom of the power connector 502 to prevent water from entering the power connector 502.

[0026] Working principle: When in use, the tee body 1 can be connected to the pipeline through the docking flange 2. Once ice forms inside the tee body 1, the sealing cover 506 can be pulled down. After pulling down the sealing cover 506, the power cord can be connected to the power connector 502 to energize the induction heating coil 501. After the induction heating coil 501 is energized, the temperature of the tee body 1 will rise rapidly, melting the ice inside the tee body 1. After the ice inside the tee body 1 melts, the power cord can be disconnected. After disconnecting the power cord, the tension spring 503 will pull the telescopic rod 5 on the spring seat 504 05 moves upward so that the sealing cover 506 is pressed against the bottom of the power connector 502 to prevent water from entering the power connector 502. At the same time, the upper protective cover 401 and the lower protective cover 404 can be sleeved on the outside of the induction heating coil 501. After the upper protective cover 401 and the lower protective cover 404 are sleeved on the outside of the induction heating coil 501, the fixing bolts 403 can be tightened to wrap the induction heating coil 501 with the upper protective cover 401 and the lower protective cover 404, thereby reducing the contact between the induction heating coil 501 and the outside world and extending the service life of the induction heating coil 501.

[0027] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
