[0024] See also Figure 1-5 , the utility model provides the following technical solutions:

[0025] A waterproof fire extinguishing device comprises a shell 1, the top of the shell 1 is open, a track 11 is provided at the bottom of the shell 1, a cover 2 is sealed and installed on the opening of the shell 1, a pipeline 4 is installed on the cover 2, a jet pipe 41 of the pipeline 4 extends out of the shell 1, the jet pipe 41 can slide in the track 11, a protective mechanism 5 is connected to the jet pipe 41, when the angle of the jet pipe 41 is adjusted on the track 11, the protective mechanism 5 can always cover the track 11, so as to prevent splashing water droplets from entering the device from the opening of the track 11, thereby improving the waterproofness of the device; all power lines of the pipeline 4 are bundled into a wire harness 6, a wiring port is provided on the cover 2, the wire harness 6 passes through the cover 2 from the wiring port, a wiring sealing mechanism 3 is installed on the wiring port, the wiring sealing mechanism 3 seals the gap between the wire harness 6 and the wiring port, prevents precipitation from entering from the wiring port, and improves the overall waterproofness of the device.

[0026] The protection mechanism 5 includes two slide grooves 51, which are arranged on both sides of the track 11. The slide grooves 51 are fixed on the inner wall of the shell 1. A groove is opened on the opposite side of the two slide grooves 51. A movable bar 52 is slidably connected in the groove. The two movable bars 52 jointly clamp a baffle 53. The two ends of the slide groove 51 extend out of the two ends of the track 11 along the inner wall of the shell 1. The injection tube 41 is penetrated in the center of the baffle 53. The movable bar 52 and the baffle 53 are both made of metal tin, that is, the movable bar 52 and the baffle 53 are both made of soft material. When the injection tube 41 rotates, it can drive the baffle 53 and the two movable bars 52 to slide in the slide groove 51. The length of the movable bar 52 and the baffle 53 is three times the length of the track 11. When the injection tube 41 moves, the baffle 53 can always cover the track 11;

[0027] The cross section of the baffle 53 is set to be curved and convex toward the side away from the shell 1. After water droplets splash on the baffle 53, they eventually gather and drip along the convexity without entering the device from both sides of the baffle 53, thereby ensuring the waterproofness of the baffle 53.

[0028] The wiring sealing mechanism 3 includes a special-shaped sealing ring 31, which is clamped on the wiring port. A connecting column 22 is provided at the end of the wiring port facing away from the shell 1. The wire harness 6 is clamped in the connecting column 22. A sealing ring 33 is provided between the wire harness 6 and the connecting column 22. A rubber threaded sleeve 32 is threadedly connected to the outer side of the connecting column 22. The upper end of the rubber threaded sleeve 32 is pressed against the top of the connecting column 22 and is sealed and connected to the wire harness 6. The sealing between the wire harness 6 and the wiring port is ensured by the special-shaped sealing ring 31, the rubber threaded sleeve 32 and the sealing ring 33 to prevent rainwater from entering the shell 1 from the wiring port.

[0029] A cover edge 21 is provided on the edge of the cover 2. The cover edge 21 is in a circular ring shape. The inner ring surface of the cover edge 21 fits with the outer wall of the shell 1. The cross section of the cover edge 21 is wedge-shaped, and the tip of the wedge points to the shell 1. The contact surface between the end of the cover edge 21 and the shell 1 is relatively flat. Rainwater falling on the cover 2 slides down the inclined surface of the wedge shape of the cover edge 21, and will not gather at the end of the cover edge 21, thereby improving the waterproofness of the cover 2.

[0030] Specifically, a protective mechanism 5 is provided at the moving track 11 of the spray pipe 41, and a baffle 53 of the protective mechanism 5 is inserted into the spray pipe 41. Both sides of the baffle 53 are clamped in the movable bar 52. Slide grooves 51 are provided at both ends of the track 11. The two movable bars 52 are respectively slidably connected with the slide grooves 51. The length of the baffle 53 is three times the length of the track 11. When the spray pipe 41 slides on the track 11, the baffle 53 can always cover the track 11, thereby preventing splashing water droplets from entering the shell 1, thereby improving the overall waterproof performance of the device;

[0031] A wiring sealing mechanism 3 is provided on the wiring port of the cover 2, and the sealing performance between the wire harness 6 and the wiring port is ensured by a special-shaped sealing ring 31, a sealing ring 33 and a rubber threaded sleeve 32, so as to prevent precipitation from entering the housing 1 through the wiring port.
