[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Embodiment 1

[0019] Please refer to Figure 1 - Figure 2 , the protection device for the cooling water flow of the electric furnace, including an alarm control cabinet 100, a water distribution support 200 is assembled on the top of the alarm control cabinet 100, and a flowmeter 300 is assembled on the water distribution support 200, and multiple groups of flowmeters 300 are provided.

[0020] Flowmeters 300 are installed in each branch to monitor and compare the inlet and return water of each branch, and the flow data obtained by the flowmeters 300 are transmitted to a specially designed control cabinet. Relevant values of the water flow are set in advance in the control system. When the monitored value exceeds the allowable deviation value, the warning light on the control cabinet lights up to remind the operator to check whether there are leakage points on each branch and the main pipeline, etc. In this way, it can ensure that the electric furnace works in a normal water cooling system and also ensure the safe use of the electric furnace.

[0021] In use, flow meters 300 are installed in each branch to monitor and compare the inlet and return water of each branch. The flow data obtained by the flow meters 300 is transmitted to a specially designed control cabinet. Relevant values of water flow are set in advance in the control system. When the monitored value exceeds the allowable deviation value, the warning light on the control cabinet lights up to remind the operator to check whether there are leakage points in each branch and the main pipeline, etc. Embodiment 2

[0022] Please refer to Figure 1 - Figure 2 , on the basis of Embodiment 1, a stabilizing component 400 is provided on the side of the alarm control cabinet 100. The stabilizing component 400 includes an arc-shaped bin 401 and a hydraulic bin 402. The arc-shaped bin 401 is located at the inner wall position of the alarm control cabinet 100, and the arc-shaped bin 401 is fixed to the alarm control cabinet 100. The hydraulic bin 402 is located inside the alarm control cabinet 100, and the hydraulic bin 402 is fixed to the alarm control cabinet 100. A gravity ball 403 is assembled inside the arc-shaped bin 401. One end of the hydraulic bin 402 is fixedly connected to an elastic airbag 404, and the other end of the hydraulic bin 402 is slidably connected to a clamping rod 405. A torsion spring rod 406 is rotatably connected to the side of the alarm control cabinet 100. A card slot 407 is provided on the side of the torsion spring rod 406. The cross-sectional shape of the card slot 407 is the same as the cross-sectional shape of the clamping rod 405. A support plate 408 is fixedly connected to the outside of the torsion spring rod 406. When the alarm control cabinet 100 shakes, the arc-shaped bin 401 fixedly connected to the alarm control cabinet 100 shakes accordingly. The gravity ball 403 in the arc-shaped bin 401 moves under the action of its own gravity, away from the elastic airbag 404, causing the elastic airbag 404 to lose its restraint and expand under its own action. The gas in the air pressure bin 402 fixedly connected to the elastic airbag 404 is extracted into the elastic airbag 404, reducing the pressure in the air pressure bin 402 and driving the clamping rod 405 slidably connected to the air pressure bin 402 to move, so that the clamping rod 405 moves out of the card slot 407 on the torsion spring rod 406. The torsion spring rod 406 then loses its restraint and rotates under its own action, driving the support plate 408 fixedly connected to the torsion spring rod 406 to rotate to the ground position for support, thereby improving the stability of the device during use.

[0023] In use, on the basis of the first embodiment, when the alarm control cabinet 100 shakes, the arc-shaped bin 401 fixedly connected to the alarm control cabinet 100 shakes accordingly. The gravity ball 403 in the arc-shaped bin 401 moves under the action of its own gravity, away from the elastic airbag 404, causing the elastic airbag 404 to lose its restraint and expand under its own action. The gas in the air pressure bin 402 fixedly connected to the elastic airbag 404 is extracted into the elastic airbag 404, reducing the pressure in the air pressure bin 402 and driving the movement of the latch 405 slidably connected to the air pressure bin 402, causing the latch 405 to move out of the card slot 407 on the torsion spring rod 406. The torsion spring rod 406 then loses its restraint and rotates under its own action, driving the support plate 408 fixedly connected to the torsion spring rod 406 to rotate to the ground position for support.

[0024] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
