DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0024] Embodiment 1

[0025] Based on the existing prior art, the spraying device only sprays to form a water curtain, which will evaporate quickly at high temperature and cannot cool the inside of the machine body. In the case of heat radiation, the temperature inside the machine body rises rapidly, causing electronic components to fail or even explode. The embodiment provides a fire-fighting robot water curtain spraying device for high-temperature fire scenes. Please refer to Figures 1-4 The embodiment provides a fire-fighting robot water curtain spraying device for high-temperature fire scenes, which can simultaneously cool the inside and outside of the fire-fighting robot in the case of high-temperature fire, avoiding excessive internal temperature. The fire-fighting robot water curtain spraying device for high-temperature fire scenes includes tracks 2 installed on both sides of the robot body 1. The robot body 1 is provided with a spraying cooling mechanism 3 for spraying and cooling the robot body 1. The robot body 1 is provided with a fire extinguishing mechanism 4 for extinguishing fire. When the robot body 1 is working to extinguish fire, water flows into the spraying cooling mechanism 3 through the water inlet pipe 405, and the heat inside the robot body 1 is absorbed and cooled through the internal lattice pipe 303 and the snake-shaped heat pipe 304, better protecting the internal electronic components. At the same time, the water flow forms a water curtain through the spraying assembly 306 and sprays out to cool the outside of the robot body 1. The position and angle of the fire water cannon 402 in the fire extinguishing mechanism 4 are adjusted to extinguish the fire source point, improving the efficiency of fire extinguishing.

[0026] Since the existing prior art spraying device only sprays to form a water curtain, which will evaporate quickly at high temperature and cannot cool the inside of the machine body, a spraying cooling mechanism 3 that can simultaneously cool the inside and outside of the robot body 1 is proposed. The spraying cooling mechanism 3 includes a water inlet pipe 301 installed inside the robot body 1, and its top extends above the robot body 1. The two sides of the water inlet pipe 301 are respectively provided with a shunt pipe 302, and the distal end of the shunt pipe 302 is respectively provided with a lattice pipe 303 for heat dissipation and cooling of the middle working area of the robot body 1. The bottom of the lattice pipe 303 is provided with a snake-shaped heat pipe 304 for heat dissipation and cooling of the robot body 1 shell. The outside of the snake-shaped heat pipe 304 is equidistantly provided with a plurality of spraying pipes 305 for fire extinguishing outside the robot body 1 walking path, and extends to the outside of the robot body 1. The top of the water inlet pipe 301 is provided with a spraying assembly 306 for spraying water curtain outside the robot body 1 to cool down. When water flows into the inside of the water inlet pipe 301, the water flows through the shunt pipe 302 and flows into the inside of the lattice pipe 303 and the snake-shaped heat pipe 304, thereby heat exchanging and cooling the temperature generated by the internal electronic components of the robot body 1 during operation through the lattice pipe 303 and the snake-shaped heat pipe 304, and forming a heat insulation water layer to reduce the influence of heat radiation on the inside of the robot body 1. After heat exchange, the water flow is sprayed out from the position of the track 2 through the spraying pipe 305 to extinguish the fire on both sides of the robot body 1.

[0027] When cooling the interior of the robot body 1, the robot body 1 shell also needs to be cooled to further protect the robot body 1, so the device is also provided with a spraying assembly 306, which includes a tripod 3061 installed at the top of the water supply pipe 301, and a flow dividing disc 3062 is installed at the top of the tripod 3061, and an annular disc 3063 is installed in the upper middle part of the water supply pipe 301, and a plurality of spraying holes 3064 are arranged in the annular disc 3063 in a ring shape at equal intervals, when the water flow is sprayed from the top of the water supply pipe 301 and hits the flow dividing disc 3062 on the tripod 3061, the water flow forms a water curtain along the inner arc surface of the flow dividing disc 3062 to spray and cool the outer surface of the robot body 1, and the water curtain can also insulate heat to a certain extent, and when the water flow flows through the annular disc 3063 on the water supply pipe 301, the water flow is sprayed through the spraying holes 3064 to form a double water curtain to spray and cool the robot body 1.

[0028] The top of the tripod 3061 is fixedly connected with a support shaft 307, and an installation groove is formed in the top center of the flow dividing disc 3062, and the top of the support shaft 307 is installed in the inside of the installation groove through a rotating bearing, when the water flow hits the flow dividing disc 3062, the impact force of the water flow drives the flow dividing disc 3062 to rotate on the support shaft 307 through the bearing, and the rotation drives the water flow to form a perfect water curtain.

[0029] The existing fire water cannon 402 can only spray water in one direction, which is not convenient for targeted adjustment to the fire source, and the fire extinguishing efficiency is relatively low, so the device is also provided with a fire extinguishing mechanism 4, which includes a connecting pipe 401 installed on the robot body 1 through a horizontal adjusting valve, and a fire water cannon 402 is installed at the top of the connecting pipe 401 through a pitch adjusting valve, and a converging spray head 403 is installed at the end of the fire water cannon 402.

[0030] The outer sides of the horizontal adjusting valve and the pitch adjusting valve are connected with waterproof motors 404 for driving them to rotate, and water receiving pipes 405 are installed on both sides of the tail end of the robot body 1, and the two water receiving pipes 405 are connected with the water supply pipe 301 and the connecting pipe 401 respectively, the water flow flows into the inside of the connecting pipe 401 through the water receiving pipes 405, and is finally sprayed out through the fire water cannon 402, and the waterproof motors 404 are used to adjust the plane angle and the pitch angle of the connecting pipe 401 and the fire water cannon 402 respectively, so that the fire source can be targeted and extinguished, and the fire extinguishing efficiency is improved.

[0031] Two sides of the robot body 1 are respectively provided with water storage tanks 501, bottom of the water storage tank 501 is provided with a drain hole extending to the outside of the robot body 1, the water in the water curtain sprayed by the shunt disc 3062 flows into the inside of the water storage tank 501, so that the water collected in the water storage tank 501 is used to locally cool the robot body 1, and the water in the water storage tank 501 is slowly discharged through the drain hole, avoiding that the water in the water storage tank 501 is heated after being accumulated for a long time, which is not conducive to the heat dissipation of the robot body 1.

[0032] Embodiment 2

[0033] On the basis of embodiment 1, as shown in Figures 1-4 As shown in the prior art, the robot body 1 does not have a mechanism for removing the roadblock in front of the vehicle body, which affects the efficiency of fire extinguishing, but the device is provided with a camera 601 above the robot body 1 and a mechanical arm 602 at the front end of the robot body 1, the situation in front of the robot body 1 is observed in real time through the camera 601 during the movement of the robot body 1, and the roadblock in front of the robot body 1 is removed by the mechanical arm 602, so that the fire fighting channel is quickly opened and the efficiency of fire extinguishing is improved.
