Description

Technical Field

[0001] This utility model relates to the field of water conservancy measurement technology, specifically to a water level benchmark. Background Technology

[0002] A water level marker is a common water level measuring device. Its main body is a long pole standing vertically on the edge of the water body, with precise graduations, resembling a vertical ruler. A float attached to the pole floats on the water surface and is connected to the marker via a connecting rod. It moves up and down with the water level, always remaining level with the water surface. Workers can quickly and intuitively obtain the current water level by observing the graduations on the float, providing reliable data for flood warnings, water conservancy project scheduling, and water resource monitoring.

[0003] Existing water level markers, when used to detect water levels, suffer from oscillations in the water surface and body, causing the floats used for these markers to swing. This results in inaccurate readings of the current water level. Furthermore, frequent oscillations can cause wear and tear on the connecting parts between the float and the marker, shortening the equipment's lifespan. Additionally, the measurement errors caused by the float's oscillations can interfere with the analysis of water level change trends, affecting the accuracy of water conservancy project management, flood and drought control decisions, and water resource allocation. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a water level indicator that can effectively solve the problem that the float of the water level indicator swings due to the fluctuation of the water surface and water body, thus making it impossible to obtain an accurate value of the current water level.

[0016] Furthermore, a locking structure is provided on the side of the upper end face of the fixing strip near the hollow marker. The locking structure includes a support strip fixedly connected to the upper end face of the fixing strip, and a second magnetic block is fixedly connected to the other side of the support strip.

[0017] A solar panel and an electronic control indicator light are fixedly connected to the upper end of the hollow pole. A controller is installed on the side of the hollow pole, and the controller is electrically connected to the solar panel and the electronic control indicator light.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] The present invention will be further described below with reference to the embodiments.

[0031] Example: Refer to Figures 1 to 6 A water level benchmark, comprising:

[0032] Base 1;

[0033] The flow control mechanism 2 includes a flow control box 21 fixedly connected to the upper end face of the base 1;

[0034] The benchmark mechanism 3 includes a hollow benchmark 31 fixedly connected to the upper end face of the slow flow box 21. A float assembly 35 is provided inside the hollow benchmark 31, and multiple anti-flow components 37 are arranged in a rectangular array on both sides of the hollow benchmark 31.

[0035] The reading and recording mechanism 4 is located on the outside of the hollow marker 31 and is in contact with the float assembly 35.

[0036] The flow-slowing mechanism 2 buffers the water flow entering the hollow marker 31 to prevent fluctuations in the water flow from affecting the movement of the float assembly 35 within the hollow marker 31, thus impacting the final reading result. The reading and recording mechanism 4 records the movement value of the float assembly 35 within the hollow marker 31 to detect the water level.

[0037] Reference Figures 1 to 2 , Figure 5 Both sides of the flow-slowing box 21 in the horizontal length direction are fixedly connected with flow-slowing grids 22, and both sides of the flow-slowing box 21 in the width direction are equipped with resistance propellers 23.

[0038] A pair of slide rails 32 are fixedly connected to both sides of the hollow marker 31 in the horizontal length direction. Multiple sets of water holes 33 are formed in a rectangular array along the vertical length direction of the hollow marker 31 on both sides between the pair of slide rails 32, and each set of water holes 33 has at least four holes. A scale 34 is formed at the center position of the hollow marker 31 on both sides of the slide rails 32 along the vertical length direction of the hollow marker 31. Telescopic curtains 36 are fixedly connected to both sides of the hollow marker 31 in the horizontal width direction.

[0039] The flow-slowing grid 22 is used to buffer the water flow entering the flow-slowing box 21. Since the flow-slowing box 21 and the hollow marker 31 are in a connected state, the flow-slowing box 21 and the hollow marker 31 are similar to the principle of communicating vessels, so that the external water flow can enter the hollow marker 31 through the flow-slowing box 21.

[0040] Reference Figures 2 to 3 The float assembly 35 includes a piston 351 that is airtightly slidably connected inside the hollow marker 31. A linkage block 352 is fixedly connected to the upper end face of the piston 351. Slide rods 353 are fixedly connected to both sides of the linkage block 352 facing the telescopic curtain 36. The other side of the slide rods 353 extends through the telescopic curtain 36 to the outside of the hollow marker 31. A first float cover 354 is fixedly connected to the bottom of the piston 351.

[0041] The piston 351 in the float assembly 35 ensures that the external water flow and the water flow inside the hollow rod 31 are kept at the same level. The first float cover 354 uses the water flow entering the hollow rod 31 to push the piston 351 to slide inside the hollow rod 31. As the piston 351 slides, it will drive the slide rod 353 to slide through the linkage block 352.

[0042] Reference Figure 1 , Figure 4 The number and position of the anti-flow components 37 correspond one-to-one with the water holes 33, and the anti-flow components 37 completely cover the water holes 33.

[0043] The anti-flow component 37 includes a fixing strip 371 fixedly connected to the side of the hollow marker 31. A telescopic structure 372 is provided on the side of the upper end face of the fixing strip 371 away from the hollow marker 31. The telescopic structure 372 includes a telescopic plate 3721 fixedly connected to the upper end face of the fixing strip 371. A top strip 3723 is fixedly connected to the other side of the telescopic plate 3721. A first magnetic block 3724 is fixedly connected to the side of the top strip 3723 facing the hollow marker 31. A first magnetic bolt 3722 is fixedly connected to the side of the top strip 3723 away from the hollow marker 31.

[0044] The telescopic plate 3721 in the telescopic structure 372 of the anti-flow component 37 can be extended and retracted to cover and open the water hole 33 submerged by the water flow at the corresponding position. The top bar 3723 extends and retracts the telescopic plate 3721 through the first magnetic bolt 3722, and the top bar 3723 is fixed after extension through the first magnetic block 3724.

[0045] Reference Figures 1 to 4 A locking structure 373 is provided on the upper end face of the fixing strip 371 near the hollow marker 31. The locking structure 373 includes a support strip 3731 fixedly connected to the upper end face of the fixing strip 371. A second magnetic block 3732 is fixedly connected to the other side of the support strip 3731. One side of the second magnetic block 3732 is fixedly connected to the side of the hollow marker 31, and the other side of the second magnetic block 3732 is magnetically connected to the first magnetic block 3724.

[0046] A solar panel 38 and an electronic control indicator light 39 are fixedly connected to the upper end of the hollow signpost 31. A controller is installed on the side of the hollow signpost 31, and the controller is electrically connected to the solar panel 38 and the electronic control indicator light 39.

[0047] The second magnetic block 3732 is fixed by the support bar 3731 in the locking structure 373. When the telescopic plate 3721 extends to the position of the second magnetic block 3732, the extension state of the telescopic plate 3721 is locked by the magnetic attraction between the second magnetic block 3732 and the first magnetic block 3724. The solar panel 38 provides power to the electronic control indicator 39.

[0048] Reference Figures 1 to 6The reading and recording mechanism 4 includes a slide bar 353 extending through the telescopic curtain 36 to the bottom of a second float 41 on one side of the hollow marker 31. Connecting blocks 42 are fixedly connected to both sides of the upper surface of the second float 41. L-shaped frames 43 are fixedly connected to the sides of the two connecting blocks 42. A slider 44 is fixedly connected to the other side of the L-shaped frame 43. The slider 44 corresponds to and is slidably connected to the slide rail 32. A first L-shaped rod 45 is fixedly connected to the side of the slider 44. A second magnetic bolt 46 is fixedly connected to the other side of the first L-shaped rod 45. The second magnetic bolt 46 corresponds to and is magnetically connected to the first magnetic bolt 3722. A second L-shaped rod 47 is fixedly connected to the side of the second magnetic bolt 46. A reader 48 is fixedly connected to the side of the second L-shaped rod 47. The reader 48 corresponds to the scale 34 and is electrically connected to the controller.

[0049] By utilizing the buoyancy of the second float 41 of the reading mechanism 4 across the horizontal plane, further buoyancy support is provided for the slide rod 353, thereby enhancing the sliding of the piston 351 within the hollow marker rod 31 and improving the accuracy of water level reading.

[0050] The working principle of this utility model is as follows:

[0051] Step 1: First, after placing the water level marker into the water conservancy area where the water level needs to be measured, the external water flow first passes through the flow-slowing grids 22 on both sides of the horizontal length of the flow-slowing box 21. The flow-slowing grids 22 initially buffer the water flow, reducing the water flow speed and reducing water flow fluctuations. Then, the water flow enters the flow-slowing box 21. The resistance paddles 23 on both sides of the width of the flow-slowing box 21 further consume the energy of the water flow, making the water flow more stable. After being doubly buffered, the water flow enters the hollow marker 31 through the connection between the flow-slowing box 21 and the hollow marker 31. During this process, the water holes 33 on the hollow marker 31 ensure the internal air pressure balance, ensuring a stable inflow of water.

[0052] The water flow entering the hollow marker 31 pushes the first float 354. Since the first float 354 is fixedly connected to the piston 351, the piston 351 will slide upward inside the hollow marker 31. The upper end face of the piston 351 is connected to the linkage block 352. The sliding rods 353 on both sides of the linkage block 352 will move with the movement of the piston 351. The sliding rods 353 extend through the telescopic curtain 36 to the outside of the hollow marker 31, and at the same time drive the telescopic curtain 36 to perform corresponding telescopic movements, ensuring that the external water flow can only enter the hollow marker 31 through the slow flow box 21. The piston 351 always keeps the water level inside the hollow marker 31 consistent with the external water level, thereby reflecting the change in water level.

[0053] Step 2: As the water level rises, when the water level submerges the water hole 33, the first magnetic bolt 3722 in the reading and recording mechanism 4 will drive the telescopic plate 3721 in the telescopic structure 372 of the anti-flow component 37 to extend, which will drive the top bar 3723 to move. When the first magnetic block 3724 on the top bar 3723 moves to the position of the second magnetic block 3732 in the locking structure 373, the two will be magnetically connected to fix the extended state of the telescopic plate 3721, preventing water from flowing back from the water hole 33 or causing disturbance, and ensuring that the float assembly 35 can stably measure the water level.

[0054] The second float 41 of the reading and recording mechanism 4, buoyed by the water surface, provides additional buoyancy support for the slide bar 353, allowing the piston 351 to slide more smoothly within the hollow marker 31. Connecting blocks 42 on both sides of the upper surface of the second float 41 connect to the L-shaped frame 43. The slider 44 on the other side of the L-shaped frame 43 slides within the slide rails 32 on both sides of the hollow marker 31, guiding the reading and recording mechanism 4 to move smoothly along the hollow marker 31. The first L-shaped rod 45 on the side of the slider 44 drives the second magnetic bolt 46 to move. The second magnetic plug 46 is magnetically connected to the first magnetic plug 3722, which can control the extension and retraction of the telescopic plate 3721 and ensure the coordinated operation of the reading mechanism 4 and the anti-flow component 37. As the reading mechanism 4 moves, the reader 48 reads the water level value corresponding to the scale 34 on the hollow marker 31. The reader 48 is electrically connected to the controller and will transmit the read data to the controller. If the water level reaches the preset warning value, the controller will control the electronic control indicator 39 to light up in time to remind the relevant personnel.
