Description

Technical Field

[0001] This utility model relates to the field of water level monitoring technology, specifically a water level monitoring device for smart water conservancy. Background Technology

[0002] Water level data is essential for studying the relationship between water level and flow rate, as well as for analyzing river sediment, ice conditions, and other factors. Therefore, it is necessary to use water level monitoring devices to conduct on-site water level measurements in the water area.

[0003] Chinese patent disclosure (CN119509655A) discloses a water level monitoring device for smart water conservancy. The device includes a base, an adjustment mechanism on top of the base, an auxiliary component on the surface of the adjustment mechanism, and a water level monitoring component connected to the end of the auxiliary component furthest from the adjustment mechanism. A protective mechanism is provided outside the water level monitoring component. The protective mechanism includes a limiting ring frame positioned outside the water level monitoring component, with a perforated protective cylinder fixed to its bottom. This smart water level monitoring device effectively reduces water flow fluctuations by using a perforated protective cylinder outside the water level monitoring component, preventing damage from direct impact of turbulent water flow. It also reduces the impact of water flow fluctuations on water level monitoring data. The cooperation between the bracket and the limiting bolt allows the limiting ring frame and the perforated protective cylinder to be adjusted and installed at different heights outside the water level monitoring component, facilitating adaptation to the height of the float and improving practicality.

[0004] However, it still has the following drawbacks: the device submerges the local water level monitoring component in the water by starting a motor, but it can only determine whether the water level exceeds the standard, not the depth of the water, making it inconvenient to judge the changes in river undulations. Therefore, we propose a water level monitoring device for smart water conservancy to solve this problem. Utility Model Content

[0005] The purpose of this invention is to provide a water level monitoring device for smart water conservancy, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water level monitoring device for smart water conservancy, comprising a base, a monitoring device disposed on the top of the base, and the monitoring device comprising a monitoring unit;

[0007] The monitoring unit includes a control box and a pressure level gauge. A traction cable composite rope is fixedly connected to the top surface of the pressure level gauge. A winding roller is fixedly sleeved on the bottom outer surface of the left end of the traction cable composite rope. A connecting cable is provided on the control box.

[0008] An adjustment section is provided on the top of the base;

[0009] The adjustment part includes a column and a sleeve. The bottom surface of the column is fixedly connected to the top surface of the base. An annular groove is formed on the outer surface of the column. The inner wall of the sleeve extends into the annular groove and is rotatably connected to the inner wall of the annular groove through a bearing.

[0010] Further improvements include a cable rotary joint, a forward and reverse motor, a protective shell, and a filter.

By setting up the traction cable composite rope and a pressure-type water level gauge, the pressure-type water level gauge is submerged to the bottom of the water. By monitoring the water pressure, the depth of the bottom is calculated. The traction cable composite rope is a rope with traction and conductivity functions, made of high-strength and conductive materials, meeting the needs of simultaneous traction operations and power transmission scenarios. Through the cable rotary joint, when the left end of the traction cable composite rope rotates with the take-up roller, it can still maintain a stable electrical connection with the cable rotary joint.

The two traction wheels are respectively fixedly sleeved on the outer surface of the stepper motor output shaft and the outer surface of the rotating shaft. The bottom surface of the fixing block is fixedly connected to the top surface of the adjusting plate. The outer surface of the traction chain is fixedly connected to the outer surface of the fixing block. By setting the stepper motor, traction chain, traction wheels and fixing block, the forward and reverse rotation of the stepper motor is controlled. The traction chain pulls the adjusting plate to move left and right, thereby adjusting the left and right position of the pressure level gauge.

[0015] A further improvement is that the outer surface of the servo motor is fixedly connected to the outer surface of the column, the gear is fixedly sleeved on the outer surface of the servo motor output shaft, and the gear ring is fixedly sleeved on the outer surface of the sleeve. By setting the servo motor, gear, and gear ring, the servo motor is started, and the mounting plate and adjusting plate are controlled to rotate within a small range to adjust the monitoring position.

[0037] The bottom surface of the stepper motor 228 and the bottom surface of the upright plate 201 are both fixedly connected to the top surface of the mounting plate 222. The outer surface of the rotating shaft 202 is rotatably connected to the front of the upright plate 201 through the second bearing seat. A limit groove is opened on the outer surface of the mounting plate 222. The outer surface of the adjusting plate 223 extends into the limit groove and is slidably connected to the inner wall of the limit groove. By setting the stepper motor 228, the fixed block 229, the traction chain 220, the upright plate 201, the rotating shaft 202, and the traction wheel 203, the stepper motor 228 is started to rotate. The traction chain 220 pulls the adjusting plate 223 to move left and right to adjust the monitoring position.

[0038] Two traction wheels 203 are fixedly sleeved on the outer surface of the output shaft of the stepper motor 228 and the outer surface of the rotating shaft 202, respectively. The bottom surface of the fixing block 229 is fixedly connected to the top surface of the adjusting plate 223, and the outer surface of the traction chain 220 is fixedly connected to the outer surface of the fixing block 229.

[0039] This device uses a PLC as the control core, connecting the PLC to a stepper motor 228, a servo motor 221, a forward / reverse motor 215, and a pressure level gauge 219. The PLC sends signals to the forward / reverse motor 215, causing its output shaft to drive the winding roller 214 to rotate. This unwinds the traction cable composite rope 216, causing the protective housing 217 and the pressure level gauge 219 to sink into the water. When the pressure level gauge 219 reading remains unchanged, it indicates that the protective housing 217 has reached the bottom. The control box 211 then sends a bottom depth signal, which is then transmitted by the PLC. The PLC controls the forward and reverse motor 215 to reverse its output shaft, lifting the pressure level gauge 219. The PLC sends a signal to the servo motor 221, whose output shaft drives the mounting plate 222 and adjusting plate 223 to rotate via gear 225 and gear ring 226. The PLC also sends a signal to the stepper motor 228, whose output shaft drives the traction wheel 203 to rotate. The traction chain 220 pulls the fixed block 229 and adjusting plate 223 to move horizontally, adjusting the front, back, left, and right positions of the pressure level gauge 219, changing the monitoring position, and preventing local bulging and depressions at the bottom of the water.
