It should be noted that, unless otherwise clearly specified and limited, the terms "install", "connect", and "set" should be understood in a broad sense. For ordinary technicians in this field, the specific meanings of the above terms in this patent can be understood according to specific circumstances.

[0019] Reference Figures 1-4 , an adjustable double-layer spray cooling device, including a connecting pipe 1, the top and middle outer walls of the connecting pipe 1 are provided with spiral grooves 9, the inner part of the spiral groove 9 at the top of the connecting pipe 1 is slidably connected to the upper layer adjustment hand wheel 2, and the inner part of the spiral groove 9 in the middle is slidably connected to the lower layer adjustment hand wheel 5, the connecting pipe 1 is provided with an upper layer water outlet 10 at the position of the upper layer adjustment hand wheel 2, and the connecting pipe 1 is provided with a lower layer water outlet 11 at the position of the lower layer adjustment hand wheel 5, so as to realize the upper and lower layer spraying, entering The water in the connecting pipe 1 can be sprayed out through the lower water outlet 11 and the upper water outlet 10. The sprayed water can adhere to the robot fire-fighting equipment to cool it down. When it is necessary to adjust the water spray volume of the lower water outlet 11 and the upper water outlet 10, turn the upper adjusting handwheel 2 to move it downward along the spiral groove 9. The downward movement of the upper adjusting handwheel 2 can narrow the gap of the upper water outlet 10, thereby reducing the water output of the upper water outlet 10. Similarly, the water output of the lower adjusting handwheel 5 can also be adjusted. The adjustment method is simple and convenient.

[0020] The upper adjusting handwheel 2 and the lower adjusting handwheel 5 are both threadedly connected with an adjusting screw 8, and one end of the adjusting screw 8 fits against the inner wall of the spiral groove 9. When it is necessary to adjust the upper adjusting handwheel 2 and the lower adjusting handwheel 5, rotating the adjusting screw 8 out of the spiral groove 9 can control the rotation of the upper adjusting handwheel 2 and the lower adjusting handwheel 5. After the adjustment is completed, rotating the adjusting screw 8 to make it re-extend into the interior of the spiral groove 9 and press it against it to lock the position of the upper adjusting handwheel 2.

[0021] The bottom of the upper adjustment hand wheel 2 is rotatably connected to the upper atomizing teeth 4, and the upper atomizing teeth 4 correspond to the upper water outlet 10. When water is sprayed from the upper water outlet 10, the sprayed water is sprayed onto the upper atomizing teeth 4, which can atomize the water so that the water mist adheres to the fire-fighting robot equipment.
