Description

Technical Field

[0001] The invention belongs to the technical field of water conservancy projects, and in particular relates to a water level measuring device for a water conservancy project. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. When measuring water levels in the field of water conservancy projects, it is often necessary to use counterweights and water level measuring wire machines for measurement. When detecting the water level in the water area, a water level detection device is often required.

[0003] The existing patent (application number: CN202222014843.X) proposes a water level detection device for a water conservancy project, including: a fixed base, a support column, a support cross plate, an adjustment seat, a winding mechanism and a water level monitoring module; the fixed base is horizontally fixed on the ground, the support column is vertically arranged on the upper surface of the fixed base, the support cross plate is horizontally arranged, and one end is fixed on the top of the support column, the adjustment seat can be slidably arranged on the lower surface of the support cross plate along the length direction of the support cross plate, and the position after sliding can be locked, the winding mechanism is assembled on the adjustment seat, the rope is wound into the winding mechanism, and its free end passes through the winding mechanism and is fixed with the water level monitoring module; the water level monitoring module includes.

[0004] When in use, the water level monitor in the prior art overcomes the problems that the detection position is fixed and the position cannot be adjusted conveniently, which easily leads to incomplete detection data, and the intelligence level is low and cannot meet the existing reservoir water level detection needs;

[0005] Although the water levels at different depths and in different areas can be detected by adjusting the length of the rope and the position of the water level monitoring module, when the rope drives the water level monitoring module down into the water, the water flow will have a certain impact force on the rope. If the water flow blows too much on the rope, it will cause the rope to shake in the water, which may affect the stability and accuracy of the water level monitoring module.

[0006] Chinese patent application number 202420127034.6 discloses a water level detection device for a water conservancy project, including a fixed base and a measuring assembly, which is specifically a circular slider sleeved on a scale, a fluorescent pointer connected to the inner wall of the circular slider, and the fluorescent pointer is located on the side of the scale with scales, and a floating ball is connected to the circular slider, which is driven by the floating ball to move up and down along the scale, and the water level data can be known through the indicated position of the fluorescent pointer;

[0007] Although this design can prevent the impact of water flow on the measuring components, it still has disadvantages. For example, when measuring water levels at different locations, the river bottom height is different. If the scale value is used to measure the water level, when the river bottom is high, moving the scale horizontally will cause the bottom of the scale to touch the river bottom, or even worse, the scale will bend or be damaged. When the river bottom is low, the bottom of the scale is too high from the river bottom, resulting in inaccurate measurement data. Therefore, a water level measuring device with strong adaptability is urgently needed to solve the above problems. Summary of the invention

Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0027] like Figure 1 As shown, a water level measuring device for a water conservancy project includes a column 1, wherein the column 1 is provided with a cross column 2, the cross column 2 is connected with a measuring component 4 via a telescopic component 3, the measuring component 4 includes a moving component 5 and a measuring column 6, the moving component 5 drives the measuring column 6 to move laterally, the measuring column 6 is connected with a counterweight block 7 via a pull rope 8, a cavity 601 is provided in the measuring column 6, the end of the pull rope 8 away from the counterweight block 7 is arranged in the cavity 601, and is connected to the moving part 602, and also includes a control component, the control component is used to control the measuring column 6 to move up and down.

[0028] In actual use, the control component may include an electric telescopic rod. A sensor, such as a weighing sensor, may be arranged in the cavity 601 to detect the magnitude of the tension applied to the rope. When the tension reaches a preset value, the electric telescopic rod is started to adjust the height of the measuring column 6. The maximum and minimum values ​​may be set. When the tension reaches the maximum value, the electric telescopic rod is started to lower the height of the measuring column 6. When the tension reaches the minimum value, that is, the pull rope is in a relaxed state, the electric telescopic rod is started to increase the height of the measuring column 6.

[0029] In a specific implementation manner, Figure 3 As shown, the moving member 602 is connected to the bottom of the cavity 601 via a first spring 603 , and one end of the moving member 602 away from the first spring 603 is connected to a moving rod 604 , and one end of the moving rod 604 passes through the cavity 601 .

[0030] In a specific implementation, the measuring component 4 also includes a U-shaped plate 401, and the moving component 5 includes a second motor 501 and a screw 502, the screw 502 is rotatably arranged in the U-shaped plate 401, the second motor 501 is used to drive the screw 502 to rotate, and the screw 502 is threadedly connected to a moving frame 402, and the measuring column 6 is arranged on the moving frame 402.

[0031] The second motor 501 may be a stepper motor, which controls the rotation direction of the screw rod 502 to control the moving direction of the moving frame 402 , so that the measuring column 6 can be controlled to move to a position to be measured according to actual conditions.

[0032] In a specific implementation, the movable frame 402 is a cylindrical structure, and slide grooves 403 are provided on both side walls. The measuring column 6 is sleeved in the movable frame 402 , and a slider matched with the slide grooves 403 is provided.

[0033] In a specific embodiment, a limiting groove 606 is provided on the outer wall of the measuring column 6, a rack set is slidably arranged in the limiting groove 606, one side of the rack set in the sliding direction is connected to the limiting groove 606 through a second spring 11, and the other side is provided with a first airbag 12.

[0034] In actual use, the movement of the rack assembly can be controlled by inflating and deflating the first airbag 12 .

[0035] In a specific embodiment, the control assembly includes a second airbag 13 , the second airbag 13 is connected to the first airbag 12 , the second airbag 13 is arranged above the measuring column 6 , and the moving rod 604 is arranged in contact with the second airbag 13 .

[0036] In a specific implementation, a driving window 14 is provided on the side wall of the movable frame 402, and the driving window 14 is provided corresponding to the limiting groove 606. A first motor 9 is provided on the movable frame 402, and a gear 901 is connected to the driving end of the first motor 9. The gear 901 is meshed with the rack 10 through the driving window 14.

[0037] When the pull rope 8 is in a relaxed state, the movable part 602 moves upward under the elastic force of the first spring 603, thereby driving the movable rod 604 to move upward and pass through the cavity 601, thereby squeezing the second airbag 13, and the gas in the second airbag 13 is squeezed into the first airbag 12, causing the first airbag 12 to expand, pushing the rack group to move, so that it engages with the gear 901, starting the first motor 9, and the gear 901 rotates, thereby driving the measuring column 6 to move upward. When it moves to a certain position, the pull rope 8 is straightened and the movable part 602 moves downward. Under the elastic force of the second spring 11, the gas in the first airbag 12 returns to the second airbag 13. At this time, the rack group is no longer engaged with the gear 901, so that the height of the measuring column 6 is fixed.

[0038] In actual design, the friction between the measuring column 6 and the moving frame 402 can be increased, thereby preventing the measuring column 6 from sliding without the action of external force.

[0039] In a specific implementation manner, Figure 5 As shown, the counterweight block 7 includes a first counterweight piece 701 and a second counterweight piece 702 . The first counterweight piece 701 is sleeved in the second counterweight piece 702 and connected to the second counterweight piece 702 via an elastic rope 703 .

[0041] When the river bottom is low, the counterweight 7 is in a suspended state. At this time, the first counterweight 701 is suspended below the second counterweight 702 through the elastic rope 703 under the action of gravity. At this time, the tension of the pull rope 8 is the largest, the first spring 603 is compressed to the limit state, the moving rod 604 is completely in the cavity 601, the second airbag 13 is in a normal state, and the rack group squeezes the first airbag 12 so that all the gas is squeezed into the second airbag 13. At this time, the rack 10 away from the side of the first airbag 12 is meshed with the gear 901, and the first motor 9 is started. When the second counterweight 702 is closed, the measuring column 6 is driven to move downward. When it moves to the point where the second counterweight 702 contacts the river bottom, the elastic rope 703 is in a normal state, that is, there is no more tension. At this time, the tension of the rope is reduced accordingly. At this time, the first spring 603 is extended accordingly, and the moving rod 604 squeezes the second airbag 13, so that part of the gas enters the first airbag 12, thereby squeezing the rack group, so that the connecting plate 101 is opposite to the gear 901, and the gear 901 cannot engage with the rack 10, so that the measuring column 6 no longer moves, which is the optimal height of the measuring column, and the water level data obtained is also the most accurate data.

[0042] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
