[0036] like Figures 1 to 7 As shown, the present application provides a laser temperature detection oil drainage and nitrogen injection fire extinguishing device, including an oil drainage and nitrogen injection body 100 and a transformer 200, the oil drainage and nitrogen injection body 100 and the transformer 200 are connected, the oil drainage and nitrogen injection body 100 provides fire extinguishing operations for the transformer 200, and also includes a laser detection component 300;

[0037] The laser detection assembly 300 includes a laser detector 310, an adjustment assembly 320 and a support assembly 330;

[0038] The laser detector 310 is movably connected to the transformer 200, and the laser detector 310 and the adjustment component 320 are fixedly connected;

[0039] The adjustment component 320 includes a horizontal coordination component 321 and a tilt coordination component 322 . The horizontal coordination component 321 is used to drive the laser detector 310 to intermittently move, and the tilt coordination component 322 is used to adjust the tilt angle of the laser detector 310 .

[0040] Further specific description: Through the design of the laser detection component 300, the laser detector 310, the adjustment component 320 and the support component 330, the laser detector 310 can be adjusted in the horizontal direction and the tilt direction, so as to monitor the temperature of the top surface components of the transformer 200. There is no need to install multiple laser detectors 310 to monitor the temperature of the top surface of the transformer 200, which saves costs and is convenient and quick to install.

[0041] Specifically, the support assembly 330 includes a protective box 331, the laser detector 310 is arranged below the protective box 331, the horizontal coordination assembly 321 is movably connected inside the protective box 331, a support plate is fixed to the side of the bottom end of the protective box 331 away from the laser detector 310, and support legs 332 are symmetrically fixed to the bottom end of the support plate, and the support legs 332 are fixed on the transformer 200.

[0042] To be further described in detail: the protective box 331 is supported by the support legs 332, and the protective box 331 provides structural support for the adjustment component 320 and the laser detector 310. The bottom height of the support legs 332 is lower than the bottom height of the laser detector 310, and the support legs 332 do not affect the movable operation of the laser detector 310.

[0043] Specifically, a reinforcing rib is fixed between the support plate and the bottom end of the protection box 331 .

[0044] Further specific description: The design of the reinforcing ribs is used to enhance the stability between the support plate and the protective box 331.

[0045] Specifically, the horizontal coordination component 321 includes an intermittent gear component;

[0046] To further explain in detail: the intermittent gear assembly is used to drive the tilt coordination assembly 322 and the laser detector 310 to move intermittently.

[0047] The intermittent gear assembly includes a driving wheel 3211 with few teeth and a driven wheel 3212 with full teeth, and the driving wheel 3211 with few teeth and the driven wheel 3212 with full teeth are meshed and connected;

[0048] A driving member 3213 is fixed on the small-tooth driving wheel 3211;

[0049] The full-tooth driven wheel 3212 and the tilt coordination component 322 are fixedly connected.

[0050] Further specific explanation: a small number of teeth are evenly spaced in an array around the small-tooth driving wheel 3211, which is used to drive the full-tooth driven wheel 3212 to intermittently move. The full-tooth driven wheel 3212 synchronously drives the tilt coordination component 322 and the laser detector 310 to intermittently rotate around the central axis of the full-tooth driven wheel 3212, so that the laser detector 310 can monitor the temperature of multiple components on the surface of the transformer 200, and there is no need to install multiple laser detectors 310 at the same time; the driving member 3213 adopts a reciprocating motor, and the output shaft of the reciprocating motor is fixedly connected to the small-tooth driving wheel 3211 in the intermittent gear mechanism. The reciprocating motor is fixed on the protective box 331. The reciprocating motor is adopted to avoid the laser detector 310 being affected by the interference of the connecting wires on the laser detector 310 during operation.

[0051] Specifically, the bottom ends of the less-toothed driving wheel 3211 and the full-toothed driven wheel 3212 are both connected with balls in an array, and the balls are slidably connected to the bottom end of the inner wall of the protection box 331 .

[0052] Further specific description: Through the design of the ball, the contact friction between the less-toothed driving wheel 3211 and the full-toothed driven wheel 3212 and the bottom end of the inner wall of the protective box 331 can be reduced during rotation, thereby extending the service life of the less-toothed driving wheel 3211 and the full-toothed driven wheel 3212.

[0053] Specifically, the tilt coordination assembly 322 includes a connecting member 3221, a tilting member 3222 and a telescopic kit 3223;

[0054] The connecting member 3221 is fixed to the bottom end of the full-tooth driven wheel 3212, the connecting member 3221 is hinged to the inclined member 3222, and the inclined member 3222 is fixedly connected to the laser detector 310;

[0055] A telescopic sleeve 3223 is provided on a side away from the hinge between the inclined member 3222 and the connecting member 3221 .

[0056] To further explain in detail: by adjusting the distance between the tilting member 3222 and the connecting member 3221 through the telescopic kit 3223, the tilting angle of the tilting member 3222 can be adjusted, and then the tilting angle of the laser detector 310 can be adjusted.

[0057] Specifically, the bottom end of the full-tooth driven wheel 3212 is fixedly connected to a fixed shaft 3224, and the bottom end of the fixed shaft 3224 movably passes through the protection box 331 and is fixedly connected to the connecting member 3221;

[0058] Reinforcement rods 3225 are symmetrically fixed on both sides of the fixed shaft 3224 , and the other end of the reinforcement rods 3225 is fixedly connected to the full-tooth driven wheel 3212 .

[0059] Further specific explanation: The reinforcing rod 3225 is designed to strengthen the connection strength between the fixed shaft 3224 and the full-tooth driven wheel 3212. In addition, the top end of the fixed shaft 3224 passes through the full-tooth driven wheel 3212 and is rotatably connected to the top end of the inner wall of the protective box 331, thereby ensuring the rotation stability of the full-tooth driven wheel 3212.

[0060] Specifically, a groove 333 for movable connection of the reinforcing rod 3225 is formed at the bottom end of the protection box 331 .

[0061] To further explain in detail: the design of the slot 333 provides spatial support for the rotation of the reinforcing rod 3225 and the fixed shaft 3224 around the central axis of the full-tooth driven wheel 3212.

[0062] Specifically, the telescopic kit 3223 includes a threaded sleeve 32231, the threaded sleeve 32231 and the connecting piece 3221 are hinged, the other end of the threaded sleeve 32231 is sleeved with a threaded rod 32232, the threaded sleeve 32231 and the threaded rod 32232 are threadedly connected, the other end of the threaded rod 32232 is rotatably connected to a connecting plate 32233, and the connecting plate 32233 and the tilting piece 3222 are movably connected.

[0063] To further explain in detail: the length of the threaded rod 32232 extending out of the threaded sleeve 32231 can be adjusted by rotating the threaded rod 32232, thereby adjusting the tilt angle of the tilting member 3222, thereby achieving the function of adjusting the tilt angle of the laser detector 310.

[0064] Specifically, the oil draining and nitrogen injecting body 100 includes a control box, and the laser detector 310 is connected to the control box.

[0065] To further explain in detail: the laser detector 310 is used to measure the temperature of multiple components and transmit the signal to the control box.

[0066] During the actual installation process of the laser temperature detection, oil draining and nitrogen injection fire extinguishing device of the embodiment of the present application, the support leg 332 is installed on the top surface of the transformer 200. When the tilt angle of the laser detector 310 needs to be adjusted, the operation is as follows:

[0067] The threaded rod 32232 is held and rotated, and the threaded rod 32232 is extended, and the tilt angle of the connecting member 3221 is adjusted, and then the tilt angle of the laser detector 310 is adjusted synchronously, so as to facilitate laser detection of multiple peripheral components;

[0068] During normal use, the motor of the driving member 3213 is started, and the output shaft of the motor drives the small-tooth driving wheel 3211 to rotate, the small-tooth driving wheel 3211 and the full-tooth driven wheel 3212 are meshed, and the full-tooth driven wheel 3212 rotates intermittently. After the side teeth on the small-tooth driving wheel 3211 drive the full-tooth driven wheel 3212 to rotate a certain angle, the full-tooth driven wheel 3212 stops rotating, and the laser detector 310 can detect the temperature of the surrounding components. As the small-tooth driving wheel 3211 continues to rotate, the teeth on the small-tooth driving wheel 3211 and the full-tooth driven wheel 3212 continue to mesh, and the laser detector 310 sequentially monitors the temperature of each component on the top surface of the transformer 200, thereby reducing the number of laser detectors 310 installed, reducing costs, and making installation convenient and quick.
