Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a water level monitoring device for water conservancy projects. Background Technique

[0002] Water level measurement and monitoring in water conservancy projects are key links to ensure their safe operation. Accurate water level measurement and effective monitoring can help managers master the water conditions of facilities such as reservoirs, rivers, and sluices, so as to give early warnings and prevent floods, and protect the lives and property of the people. In addition to measuring the water level, monitoring the water level is equally important. The purpose is to timely master the water level changes for early warning and flood prevention. Modern monitoring equipment and technologies can effectively achieve this goal, so water level monitoring plays an important role in water conservancy projects.

[0003] At present, the commonly used water level monitoring method is to install instruments such as water level gauges and flow meters in waters such as river banks to monitor water level changes in real time. Through the readings of the water level gauge, accurate water level data can be calculated. The advantage of this method is that the data is accurate, but since the instrument is located by the water, it is inevitably eroded by water vapor, so it needs to be maintained and replaced regularly. In addition, the water level gauge is usually installed in the middle of the river channel, and the whole device needs to be removed by the staff during maintenance, which is rather cumbersome to operate. Content of the Utility Model

[0004] To solve the defects existing in the prior art, the utility model provides a water level monitoring device for water conservancy projects.

[0005] The technical solution adopted by the utility model is: a water level monitoring device for water conservancy projects, including a base and a transmission rod. A column is arranged on the base, a lifting column is arranged on the column. The lifting column is a hollow rectangular structure with an opening on the right side. A servo motor is arranged on the lifting column. A threaded lead screw is arranged inside the lifting column. The threaded lead screw is connected to the output end of the servo motor. A lifting plate is arranged inside the lifting column. One end of the lifting plate is sleeved on the threaded lead screw. A sliding member is slidably connected to the lifting plate. A detachable radar water level gauge is arranged on the sliding member. A movable rotating seat is arranged on the sliding member. A fixed rotating seat is arranged on the lifting column. Two ends of the transmission rod are respectively rotatably connected to the movable rotating seat and the fixed rotating seat.

[0006] A further improvement to the above solution is that the lifting plate is a hollow rectangular plate. A chute is arranged on the lifting plate. The chute is a space structure that is narrow outside and wide inside. A sliding rod is arranged on the sliding member. A pulley is arranged at the end of the sliding rod. The pulley, the sliding rod and the chute are slidably connected in cooperation.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following is a description of the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present utility model and are not intended to limit the present utility model.

[0021] A water level monitoring device for water conservancy projects, including a base 1 and a transmission rod 2. A column 3 is arranged on the base 1, and a lifting column 4 is arranged on the column 3. The lifting column 4 is a hollow rectangular structure with an opening on the right side. A servo motor 5 is arranged on the lifting column 4, and a threaded lead screw 6 is arranged inside the lifting column 4. The threaded lead screw 6 is connected to the output end of the servo motor 5. A lifting plate 7 is arranged inside the lifting column 4, and one end of the lifting plate 7 is sleeved on the threaded lead screw 6. By controlling the rotation of the threaded lead screw 6 by the servo motor 5, the lifting of the lifting plate 7 inside the lifting column 4 is controlled. A sliding member 8 is slidably connected to the lifting plate 7, a detachable radar water level gauge 9 is arranged on the sliding member 8, a moving rotating seat 10 is arranged on the sliding member 8, and a fixed rotating seat 11 is arranged on the lifting column 4. Both ends of the transmission rod 2 are rotatably connected to the moving rotating seat 10 and the fixed rotating seat 11 respectively. When the lifting plate 7 descends, both sides of the transmission rod 2 rotate, driving the sliding member 8 to slide towards the direction close to the lifting column 4, so that the sliding member 8 reaches the low-lying area of the shore after the lifting plate 7 descends, which is convenient for the staff to repair and replace the radar water level gauge 9 without removing the entire device. When the repair and replacement of the radar water level gauge 9 are completed, the lifting plate 7 is controlled to rise, and the transmission rod 2 drives the sliding frame to slide away from the lifting column 4, so that the sliding frame reaches the end far from the lifting column 4 after the lifting plate 7 is reset, thereby realizing the monitoring of the water level.

[0022] Among them, the lifting plate 7 is a hollow rectangular plate, and a chute 12 is arranged on the lifting plate 7. The chute 12 is a space structure with a narrow outer part and a wide inner part. A sliding rod 13 is arranged on the sliding member 8, and a pulley 14 is arranged at the end of the sliding rod 13. The pulley 14, the sliding rod 13 and the chute 12 are slidably connected in cooperation. By the sliding connection of the pulley 14, the sliding rod 13 and the chute 12 in cooperation, the sliding member 8 is stably connected to the lifting plate 7. The setting of the pulley 14 can reduce friction and increase the stability of the device.

[0023] Among them, when the lifting plate 7 is at the highest position, it is parallel to the transmission rod 2, and the transmission rod 2 is slightly longer than the lifting column 4. During the descent of the lifting plate 7, it is ensured that the radar water level gauge 9 will not collide with the column 3, preventing damage to the radar water level gauge 9.

[0024] Among them, an installation frame 15 is arranged on the lifting column 4, and a control box 16 is arranged on the installation frame 15.

[0025] Among them, several support rods 17 are connected between the column 3 and the base 1, and several fixing nails 18 are arranged on the base 1. The stability of the device is increased, preventing tipping and damage due to environmental problems.

[0026] Working principle:

[0027] The staff controls the rotation of the threaded lead screw 6 through the servo motor 5, and further controls the lifting of the lifting plate 7 inside the lifting column 4. A moving rotary seat 10 is arranged on the sliding member 8, and a fixed rotary seat 11 is arranged on the lifting column 4. The two ends of the transmission rod 2 are rotatably connected to the moving rotary seat 10 and the fixed rotary seat 11 respectively. When the lifting plate 7 descends, both sides of the transmission rod 2 rotate, driving the sliding member 8 to slide towards the direction close to the lifting column 4, so that the sliding member 8 reaches the low position on the shore after the lifting plate 7 descends, facilitating the staff to repair and replace the radar water level gauge 9 without disassembling the whole device. When the repair and replacement of the radar water level gauge 9 are completed, the lifting plate 7 is controlled to rise, and the transmission rod 2 drives the sliding frame to slide away from the lifting column 4, so that the sliding frame reaches the end far from the lifting column 4 after the lifting plate 7 is reset, thus realizing the monitoring of the water level.
