[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This utility model provides a technical solution: an automatic monitoring and control device for channel water level in a cross-basin water transfer project, including a channel slope 1, a gate frame 4 installed on the channel slope 1, a gate plate 2 slidably connected to the inner side of the gate frame 4, a mounting frame 12 fixedly connected to the top side of the gate frame 4, a third electric cylinder 7 installed on the top of the mounting frame 12, a base 11 set at the bottom of the mounting frame 12, and the lower end of the third electric cylinder 7 connected to the top side of the base 11. This structure allows the third electric cylinder 7 to push the base 11 and the waveguide 3 and radar level gauge body 14 on the base 11 to adjust their height, thereby ensuring that the measurement range of the radar level gauge body 14 is within a predetermined range. A first electric cylinder 5 is fixed to the top of the gate frame 4 by a bracket. One end is fixedly connected to the top of the gate plate 2 by bolts. This structure can automatically raise and lower the gate plate 2 by pushing the first electric cylinder 5. The first electric cylinder 5 is connected to the top of the gate plate 2. A base 11 is installed on the top side of the gate frame 4. The radar level gauge body 14 is set on the top of the base 11. The outer wall of the radar level gauge body 14 is set with a heat insulation cover 13. The bottom of the base 11 is set with a waveguide 3. The outer wall of the waveguide 3 is set with a heat insulation layer 15. The outer wall of the heat insulation layer 15 is set with a protective layer 16. The heat insulation layer 15 is made of heat insulation rock wool, and the protective layer 16 is made of high temperature resistant rubber. The protective layer 16 and the heat insulation layer 15 can play a role in preventing impact and heat preservation for the waveguide 3, ensuring the signal transmission effect of the waveguide 3. The outer wall of the protective layer 16 is set with A heat-conducting layer 9, made of polytetrafluoroethylene, is provided. This structure serves both to protect the waveguide 3 from corrosion and to absorb heat, thus preventing damage from low temperatures that could affect signal transmission. The outer wall of the waveguide 3 is provided with an insulation layer 15 and a protective layer 16. A second electric cylinder 6 is fixedly connected to the top side of the gate frame 4. One end of the second electric cylinder 6 is connected to a fixing frame 8. A through hole is opened in the center of the fixing frame 8. Piercing rods 10 are evenly distributed in a circular pattern around the bottom of the fixing frame 8. The through holes correspond to the positions of the waveguide 3. The piercing rods 10 are distributed on the outer side of the waveguide 3. This structure... The lifting and lowering of the fixed frame 8 can drive the lifting and lowering of the puncture rod 10. The puncture rod 10 allows the radar level gauge body 14 to be used normally in cold weather. During the lifting and lowering process, the puncture rod 10 can break the ice on the liquid surface, thereby ensuring the signal transmission effect of the radar level gauge body 14 and ensuring the detection accuracy of the radar level gauge body 14. The puncture rod 10 is set at the bottom of the fixed frame 8. The bottom of the puncture rod 10 has a sharp structure. The second electric cylinder 6 of this device can push the fixed frame 8 and the puncture rod 10 to automatically reciprocate lifting and lowering. During the use of this device, the liquid level is monitored by the radar level gauge body 14, and then the liquid level signal is transmitted. The PLC controller receives the data and, after liquid level judgment, activates the first electric cylinder 5 to achieve automatic control.

[0023] Working principle: When using the automatic monitoring and control equipment for channel water level in this inter-basin water transfer project, the third electric cylinder 7 first pushes the base 11 and the height of the radar level gauge body 14 and waveguide 3 on the base 11 to adjust the height so that the radar level gauge body 14 is at a suitable working height. During operation, the radar level gauge body 14 monitors the channel water level. When the water level exceeds the set value, the first electric cylinder 5 drives the gate 2 to open, allowing the water in the channel to be discharged. When the water level in the channel drops to the set value, the first electric cylinder 5 pushes the gate 2 to close. If the water surface freezes in cold weather, the second electric cylinder 6 pushes the fixing frame 8 and the piercing rod 10 to automatically reciprocate up and down, so that the piercing rod 10 impacts and breaks the ice layer, thereby ensuring the normal transmission of the monitoring position signal of the radar level gauge body 14 and ensuring the monitoring accuracy of the radar level gauge body 14.
