A water outlet pipe 5 is fixedly connected to the side wall of the water storage tank 4. A water pump 6 is installed on the water outlet pipe 5. One end of the water outlet pipe 5 away from the water storage tank 4 penetrates through the frame 3 and extends to the inside and is fixedly connected with a telescopic hose 8. One side of the telescopic hose 8 away from the water outlet pipe 5 is fixedly connected with a flow dividing cover 9. Rotating rods 10 are fixedly connected to both the left and right sides of the flow dividing cover 9. The rotating rods 10 are rotatably connected to the inner wall of the frame 3 through bearings. A plurality of sprinkler heads 11 are fixedly connected to the bottom of the flow dividing cover 9. The inside of the flow dividing cover 9 is a cavity structure. The number of both the sprinkler heads 11 and the hydrogenation reactors 2 is four.

[0022] Among them, the flow dividing cover 9 is located above the hydrogenation reactor 2, and each sprinkler head 11 corresponds to directly above each hydrogenation reactor 2.

[0023] It should be noted that the hydrogen leakage detector 15 usually uses an electrochemical or semiconductor sensor to detect hydrogen. These sensors can sense extremely low concentrations of hydrogen and change the electrical signal when a leakage is detected. When the hydrogen concentration exceeds a preset threshold, the leak detector will trigger a signal, and this signal can be transmitted in a wired or wireless manner.

[0024] The flow dividing cover 9 has an effect of dividing the water flow, so that the water is sprayed out from a plurality of sprinkler heads 11, and each hydrogenation reactor 2 below the sprinkler heads 11 can be sprayed and wetted for cooling.

[0025] A driving member for adjusting the angle of the diversion shroud 9 is provided on the frame 3. The driving member includes a servo motor 12 which is fixedly installed on the side wall of the frame 3. A driving gear 14 is fixedly connected to the output shaft of the servo motor 12.

[0026] It should be noted that by providing the driving member, the diversion shroud 9 can be driven to rotate forward and backward to adjust the angle by the forward or reverse rotation of the servo motor 12, so as to change the spraying position of the spray head 11, thereby expanding the spraying range and making the water cover the hydrogenation reactor 2 more comprehensively.

[0027] Please refer to Figure 1 , a controller 16 and an alarm 17 are fixedly installed on the top of the frame 3. Hydrogen leakage detectors 15 are provided at the pipe connection points on the hydrogenation reactor 2.

[0028] Through the setting of the hydrogen leakage detectors 15, the hydrogen leakage detectors 15 can monitor the pipe connection points in real time. Once leakage occurs, it is convenient to start the spraying mechanism in time for wet cooling, and at the same time, the alarm 17 gives an alarm.

[0029] The working principle of the above embodiment is as follows: When in use, the hydrogen leakage detectors 15 on the pipeline monitor in real time whether hydrogen leaks. Once hydrogen leakage is detected, a signal will be transmitted to the controller 16 in time, so that the controller 16 starts the water pump 6, the servo motor 12 and the alarm 17. The alarm 17 will give an alarm. At the same time, the water in the water storage tank 4 will be conveyed into the diversion shroud 9 and sprayed out under pressure from multiple spray heads 11, so as to spray water on each hydrogenation reactor 2 below. At the same time, the servo motor 12 will drive the driving gear 14 to rotate forward or backward, so that the driven gear 13 can rotate, thereby driving the diversion shroud 9 to swing back and forth to increase the spraying range, wet and cool the leakage point to eliminate static electricity, and avoid fire and explosion accidents.
