The fixed disc 3 is provided with a cable pipe 5 and a water pipe 9 for leading in a cable and a water hose 17 into the shell 1, and the cable pipe 5 and the water pipe 9 are suitable to be close to the rotating motor 6. It should be noted that the rotating motor 6 can only rotate 180 degrees, so as to prevent winding faults caused by insufficient reserved lengths of water pipes and cables, and the rotating speed of the rotating motor should meet the requirement of detecting initial fire.

The water spraying device is located at the lower part in the shell 1 and comprises a hose 17, a water spraying gun 14 and a driving mechanism, wherein the driving mechanism of the embodiment is a link mechanism. The link mechanism includes a support plate 10, a first rotary column 11, a second rotary column 13, a third rotary column 15, a hydraulic lever 16, a branch pipe 21, an electromagnetic valve 22, and the like. The surface of the hose 17 is provided with a rubber soft layer, and a nylon reinforcing layer is arranged in the rubber soft layer, so that the strength of the hose 17 is increased, and the hose 17 is prevented from being damaged due to long-time use. The hose 17 is connected to a fire branch pipe through a water pipe 9 and is connected to a monitor 14 inside the housing 1. The water spraying gun 14 extends out of the sliding groove 12 of the shell 1, and the spraying head is arranged outside.

The camera 19 acts both as a flame detector and as a detector of the drop point of the sprayed water. The smoke detector 20 may be a temperature detector or a carbon monoxide detector, etc., depending on the material on which the environment is on fire.

The detection signal of the detector is transmitted to the chip arranged in the shell, and the chip is arranged in the closed space below the fixed disc 3, so that the adverse effect of the environment on the chip is avoided. The chip sends out a control command to control the rotation of the rotating motor 6 and the opening and closing of the electromagnetic valve 22, so that the water flow sprayed from the water spraying gun 14 can be accurately sprayed to the ignition part. In order to increase the safety factor, a spare chip is installed in the chip box, a detection signal is simultaneously sent to the chip in the chip box, and when the chip in the shell breaks down, the chip in the chip box can control the rotating motor 6 and the electromagnetic valve 22.

The detection device can also be arranged on the upper part of the water spraying gun 14 and the outer wall of the shell 1, so that the weight of the fixing plate 18 is increased, and the requirement of retraction of the hydraulic rod 16 is met.

Example 2.

The difference between the present embodiment and embodiment 1 is the driving mechanism of the water spraying gun, and the driving mechanism of the water spraying gun of the present embodiment is driven by a small motor. As shown in fig. 3, a chute plate 23 is fixedly installed on both sides of the chute 12, and the chute plate 23 is installed inside the housing 1 for aesthetic reasons. The chute plate 23 is rotatably connected with the second rotary column 13, one end of the second rotary column 13 is connected with a small motor, the small motor is installed on the chute plate 23, and the water spraying gun 14 is fixedly connected with the second rotary column 13.

When the initial fire is extinguished, the chip sends a command to control the rotation of the small motor, so that the angle of the water spraying gun 14 is adjusted, and the water column is sprayed to the fire part. In order to reduce the stress of the small motor, a counterweight is arranged at the position of the connecting hose 17 at the tail end of the water spraying gun 14, so that the gravity center of the water spraying gun 14 is adjusted near the second rotary column 13.

Example 3.

The present embodiment is different from the two embodiments described above in the driving mechanism of the water spraying gun, and the driving mechanism of the water spraying gun of the present embodiment adopts a gear structure, as shown in fig. 4. The gear mechanism comprises a gear 25, a half gear 26, a bearing 27, a hollow shaft 28, a fixing piece 29 and the like, wherein the gear 25 is fixedly installed in the shell 1 together with a driving motor thereof, the gear 25 is meshed with the half gear 26 to be rotatably connected, the hollow shaft 28 is fixed in the shell 1 and is connected with the half gear 26 through the bearing 27, one end of the hollow shaft 28 is connected with the hose 17, the other end of the hollow shaft 28 is connected with the tail of the water spray gun 14, and the water spray gun 14 is fixed on the half gear 26 through the fixing piece 29.

To alleviate gear stress due to the weight of the monitor 14, a counterweight is mounted on the half gear 26 such that the overall center of gravity of the monitor 14, the half gear 26, and the counterweight is located near the hollow shaft 28.

The hose 17 is connected with the water pipe 9 on the fixed disc 3 through a preformed hole of the rotating disc 8, and the detector and the camera cable on the fixed plate 18 and the cable of the gear 25 driving motor are connected with the fire-fighting bus through the preformed hole of the rotating disc 8 and the cable pipe 5 on the fixed disc 3. Since the water spraying gun 14, the gear mechanism, the hose 17 and the cable 24 rotate along with the housing in the housing 1, no winding or failure occurs, and enough hose and cable are reserved in the cavity between the rotary disc 8 and the fixed disc 3.

Embodiment 1 adopts water as the actuating mechanism of water pistol, can avoid the adverse effect of high temperature flue gas to driving motor during the conflagration, but the control to solenoid valve 22 needs the accuracy, in case the adjustment is excessive, needs to cut off water and utilizes the dead weight of shower nozzle to adjust back. Example 2 solves the adjustment problem of example 1, but the initial fire below the apparatus cannot be extinguished due to the position restriction of the second rotary column 13. Embodiment 3 solves the disadvantages of embodiment 1 and embodiment 2, and the water spraying gun can be adjusted back and forth at any angle within the range of the chute 12, and the initial fire under the device can be extinguished.
