Technical Field

[0001] The utility model relates to the technical field of water level monitoring of hydraulic engineering, in particular to a water level monitoring device for hydraulic engineering. Background Art

[0002] In order to monitor the water level changes of water bodies such as reservoirs, rivers, lakes, and farmland irrigation in real time and accurately, and provide data support for the safe and stable operation of water conservancy projects, water level monitoring devices are usually used to measure the water levels of rivers, lakes, reservoirs and other water bodies, and provide real-time water level data to facilitate project monitoring and management. The existing real-time monitoring of water levels in farmland usually uses a float-type water level gauge that uses the rise and fall of the float to reflect water level changes.

[0003] After searching, the Chinese patent "A water level monitoring device for water conservancy projects" authorization announcement number "CN219455255U" uses a base and stabilizing nails to enable the water level monitoring device to be plugged into farmland with harder soil, ensuring that the water level monitoring device is stably installed on the farmland.

[0004] However, since the contact area of ​​the stabilizing nails inserted into the farmland is limited, the water level monitoring device is subjected to the impact of water flow for a long time, which can easily cause the water level monitoring device and the farmland to become loose, thereby affecting the accuracy of the water level monitoring device in monitoring the farmland water level.

[0005] Therefore, a water level monitoring device for water conservancy projects is proposed to solve the above problems. Utility Model Content

[0024] When implementing: Figure 1-4 As shown, a water level monitoring device for a water conservancy project comprises: a support column 1, a telescopic frame 2 is fixedly connected to the top of the support column 1, a water level measuring frame 3 is fixedly connected to the bottom of the telescopic frame 2, a buoyancy rod 4 is slidably connected to the inner wall of the telescopic frame 2, and the front end of the buoyancy rod 4 is slidably connected to the inner wall of the water level measuring frame 3; an anti-deviation mechanism 5, the anti-deviation mechanism 5 is arranged on the surface of the support column 1; wherein the anti-deviation mechanism 5 comprises an air cylinder 51 fixedly connected to the inner wall of the support column 1, an air rod 52 is slidably connected to the inner wall of the air cylinder 51, and the bottom end of the air rod 52 is fixedly connected to a ground plug Nail 53, the surface of the ground nail 53 is fixedly connected with a driven frame 54, the surface of the driven frame 54 is slidably connected to the inner wall of the support column 1, the bottom of the driven frame 54 is fixedly connected with annularly distributed anti-loosening nails 55, the inner top wall of the air cylinder 51 is connected with an air intake pipe 510, the other end of the air intake pipe 510 passes through and extends out of the inner wall of the support column 1, a one-way valve 512 is embedded and installed on the surface of the air intake pipe 510, the one-way valve 512 is used to prevent the gas in the air cylinder 51 from being discharged through the air intake pipe 510, and the inner wall of the air intake pipe 510 is threadedly connected with a sealing cover 511.

[0025] The telescopic frame 2 includes a telescopic plate and a telescopic block. The surface of the telescopic block is slidably connected to the inner wall of the telescopic plate. The inner wall of the telescopic plate is rotatably connected to a screw rod. The surface of the screw rod is threadedly connected to the inner wall of the telescopic block. One end of the screw rod is fixedly connected to a servo motor. The surface of the servo motor is fixedly connected to the inner wall of the telescopic plate. The surface of the buoyancy rod 4 is slidably connected to the inner wall of the telescopic block. The top of the water level measuring frame 3 is fixedly connected to the bottom of the telescopic block.

[0026] It should be noted that the water level measuring frame 3, buoyancy rod 4, servo motor, one-way valve 512, etc. in the above description are all relatively mature devices in the existing technology. The specific models can be selected according to actual needs. At the same time, the servo motor can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0027] When the water level monitoring device needs to be installed on the farmland, the support column 1 is placed at the location of the farmland where it needs to be installed, and the sealing cover 511 is rotated to open the air inlet of the air inlet pipe 510. The air inlet of the electric air pump (the model of the electric air pump is selected according to actual needs and is not described here) is installed at the air inlet of the air inlet pipe 510, and the power of the electric air pump is manually turned on to allow the electric air pump to extract external gas, compress it and transport it into the air inlet pipe 510. The gas in the air inlet pipe 510 passes through the single The gas in the air cylinder 51 is delivered to the valve 512. The gas in the air cylinder 51 is sufficient to push the air rod 52 downward. The downward movement of the air rod 52 drives the ground nail 53 and the driven frame 54 to move downward. The ground nail 53 moves downward and is inserted into the farmland soil. The driven frame 54 moves downward and drives three inclined anti-loosening nails 55 to move downward and insert into the farmland soil, so that the support column 1 is stably installed on the farmland. At this time, the connection between the electric air pump and the intake pipe 510 is released, and the sealing cover 511 is threadedly installed on the intake pipe 510.

[0028] The servo motor is manually turned on, and the output shaft of the servo motor rotates through the screw rod to drive the telescopic block to the appropriate position, so that the water level measuring frame 3 moves to the appropriate water level. The water in the farmland flows in through the filter screen at the bottom of the water level measuring frame 3 and the through hole at the front end of the water level measuring frame 3. The excessive water level in the water level measuring frame 3 pushes the buoyancy rod 4 to move upward. By observing the height of the buoyancy rod 4 on the water level measuring frame 3, the height of the farmland water level can be monitored.

[0029] like Figure 3 As shown, an air storage groove 56 is provided on the inner wall of the ground nail 53, and a fixing nail 57 is slidably connected to the inner wall of the air storage groove 56. A corrugated hose 58 is connected to the inner wall of the air cylinder 51, and the bottom end of the corrugated hose 58 is connected to the air storage groove 56. A ring-shaped fixing block 59 is fixedly connected to the lower end of the surface of the anti-loosening nail 55. The bottom end of the anti-loosening nail 55 is in the shape of a cone, and the lower end of the surface of the anti-loosening nail 55 forms an angle with the horizontal plane. The lower end of the surface of the ground nail 53 and one end of the fixing nail 57 are both in the shape of a cone.

[0030] When the gas rod 52 moves downward to expose the gas inlet end of the corrugated hose 58, part of the gas in the gas cylinder 51 flows into the gas storage tank 56 through the corrugated hose 58. The excess gas in the gas storage tank 56 pushes the fixing nail 57 to move and insert into the soil, so that the fixing nail 57 is stably inserted into the soil. The anti-loosening nail 55 moves downward and drives the fixing block 59 to move downward and insert into the soil, so that the anti-loosening nail 55 is stably inserted into the soil.

[0031] When the utility model is in use, the support column 1 is placed at the farmland location where it needs to be installed, the sealing cover 511 is rotated to open the air inlet of the air inlet pipe 510, and the air inlet of the electric air pump is installed at the air inlet of the air inlet pipe 510. The power supply of the electric air pump is manually turned on, so that the electric air pump extracts external gas and compresses it to be transported into the air cylinder 51 through the air inlet pipe 510 and the one-way valve 512. The gas in the air cylinder 51 is sufficient to push the gas rod 52 downward, and the ground nail 53 is moved downward and inserted into the soil of the farmland. The gas rod 52 moves downward to drive the ground nail 53 and the driven frame 54 to move downward. The air rod 52 moves downward to expose the air inlet end of the corrugated hose 58, and part of the gas in the air cylinder 51 flows into the air storage tank 56 through the corrugated hose 58. The excess gas in the air storage tank 56 pushes the fixing nail 57 to move and plug into the soil, so that the fixing nail 57 is stably plugged into the soil, and the driven frame 54 moves downward to drive the three inclined anti-loosening nails 55 and the fixing block 59 to move downward and plug into the farmland soil, so that the support column 1 is stably installed on the farmland. At this time, the connection between the electric air pump and the air inlet pipe 510 is released, and the sealing cover 511 is threadedly installed on the air inlet pipe 510.
