Description

Technical Field

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

[0002] Channel water level monitoring is a crucial step, as it helps us understand the real-time status of the channel and ensure its normal operation. In practical applications, monitoring devices are typically placed beside the channel to monitor the water level in real time.

[0003] A search revealed Chinese Patent Publication No. CN221594029U, published on August 23, 2024, which discloses a monitoring device for waterway level safety monitoring. By incorporating a displacement sleeve, radar level gauge, movable rod, waterproof electric push rod, column, and transmission screw, it offers the advantage of convenient maintenance, allowing the radar level gauge to gradually approach the column, making it easier for staff to perform maintenance operations. Furthermore, the inclusion of an extension component and movable rod provides the advantage of extended length, enabling flexible changes to the radar level gauge's installation position, making it well-suited for various application needs.

[0004] However, in actual use, since the device is usually placed horizontally in the waterway, it is easily damaged in a collision when a ship accidentally bumps into it due to the lack of an effective anti-collision design. This not only affects the normal operation of waterway level monitoring, leading to interruption and loss of data acquisition, but also increases maintenance costs and workload. In order to solve the above problems, this application proposes a waterway level monitoring device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a waterway level monitoring device. Through the design of an anti-collision mechanism, when a ship scrapes against the device, the pulley rotates to change the direction of force, mitigating the damaging force of the scraping. If the ship accidentally collides with the side of the crossbar, the compressed spring bends to absorb the impact force. The rotation of the crossbar causes the auxiliary block to rotate along the top ring groove, stabilizing the position of the crossbar. If the ship's collision direction is directly in front of the horizontal position of the crossbar, when the straight-line collision pressure arrives, the buffer plate compresses the buffer spring to release the pressure, reducing the risk of deformation and damage to the device, thus solving the problems mentioned in the background art.

[0006] A waterway water level monitoring device includes an ultrasonic water level gauge; the ultrasonic water level gauge is equipped with an anti-collision mechanism; the anti-collision mechanism includes a crossbar, the front end of which is equipped with a pulley that can rotate upon impact, the rear of which is equipped with a compression spring that can bend upon impact, a support plate for supporting the crossbar against sagging below the compression spring, and a top ring groove for guiding the crossbar to rotate upon impact on the upper surface of the support plate, an auxiliary block being provided in the top ring groove, a plate groove being provided on one side of the crossbar, and a buffer plate being provided in the plate groove, and a set of guide rods for guiding displacement upon impact being provided on each side of the buffer plate, and a buffer spring for impact-resistant buffering being sleeved on the outer side of the guide rods; an adjustment assembly includes a vertical frame, a threaded screw being installed in the vertical frame, an I-shaped slider that can slide and rise along the inner side of the vertical frame being threadedly connected to the threaded screw, and a circular seat for rotatably adjusting the position of the ultrasonic water level gauge being provided below the threaded screw.

[0007] In a preferred embodiment, the auxiliary block is fixedly connected to the crossbar, and the ultrasonic level gauge is installed on the front side of the crossbar. The compression springs are provided in multiple sets and are evenly distributed between the crossbar and the I-shaped slider.

[0008] In a preferred embodiment, the threaded screw is disposed inside the upright frame, and a drive motor is mounted above the upright frame, with the output shaft of the drive motor fixedly connected to the threaded screw.

[0009] In a preferred embodiment, a connecting rod is installed on the side of the I-shaped slider near the crossbar, the crossbar is fixedly connected to the connecting rod by a compression spring, the front end of the support plate has a circular structure, and its rear end is fixedly connected to the connecting rod.

[0010] In a preferred embodiment, the plate groove is formed on the upper surface of the circular seat. A set of guide grooves is formed on each of the front and rear sides inside the plate groove, and a set of inner sliders is slidably arranged in each of the two sets of guide grooves. The guide rod is located in the guide groove, and the inner slider is fixedly connected to the front end of the guide rod. The rear end of the guide rod passes through the plate groove and is connected to a limit block. The front end of the buffer spring is connected to the inner slider, and its rear end is fixedly connected to the inner wall of the guide groove.

[0011] In a preferred embodiment, a base is provided below the circular seat, and a set of mounting holes are provided around the base. A circular groove is provided inside the base, and the circular seat is located in the circular groove. A rotary motor is installed below the inside of the circular groove, and the output shaft of the rotary motor is fixedly connected to the circular seat.

[0012] In a preferred embodiment, a bottom ring groove is provided above the inside of the circular groove, and multiple sets of limiting sliders are equidistantly arranged in a ring shape inside the bottom ring groove, and the limiting sliders are fixedly connected to the circular seat.

[0013] Beneficial effects:

[0014] 1. By designing an anti-collision mechanism, when a ship is traveling and scrapes against the device, the ship will drive the pulley to rotate, changing the direction of the force and converting the destructive force generated by the scraping into its own rotational power, making the device less likely to be damaged. If the ship accidentally hits the side of the crossbar, the crossbar will bear the impact force. The pressure generated by the collision will push the crossbar, causing the compressed spring to bend and effectively absorb the impact force, buffering the energy brought by the collision. At the same time, when the crossbar rotates, it will drive the auxiliary block to rotate along the top ring groove, making it less likely for the crossbar to shift its position after the impact. If the ship's collision direction is directly in front of the horizontal position of the crossbar, when the linear extrusion force is transmitted, the buffer plate slides along the slide rail in the plate groove, causing the buffer spring to compress and release the extrusion force, effectively reducing the risk of serious deformation and damage to the device due to continuous extrusion.

[0015] 2. To further enhance the adaptability and ease of maintenance of this device in complex waterway environments, an adjustment component was designed. When a large vessel needs to pass through a narrow waterway, the crossbar, originally positioned above the waterway, may obstruct the vessel's passage. The rotary motor drives the circular base to rotate smoothly, moving the crossbar away from the space above the waterway. This design resolves the spatial conflict between vessel passage and the monitoring device, ensuring the smooth navigation of large vessels in narrow waterways and preventing potential damage to the monitoring device and the vessel itself caused by a vessel forcibly passing through. During the maintenance of the ultrasonic level gauge, firstly, the rotary motor moves the crossbar away from the waterway. Then, as the threaded screw rotates, the I-beam slider descends smoothly along the inner side of the vertical frame. As the I-beam slider descends, the ultrasonic level gauge is simultaneously lowered to a height suitable for operation. This design eliminates the problem of workers needing to climb to heights for traditional maintenance, improving the safety and efficiency of maintenance work. Attached Figure Description

[0024] Please see Figures 1-6 As shown, a waterway water level monitoring device includes an ultrasonic water level gauge 1; the ultrasonic water level gauge 1 is equipped with an anti-collision mechanism 2; the anti-collision mechanism 2 includes a crossbar 21, a pulley 22 that can rotate upon impact is installed at the front end of the crossbar 21, a compression spring 23 that can bend upon impact is provided at the rear of the crossbar 21, a support plate 25 for supporting the crossbar 21 to prevent sagging is provided below the compression spring 23, and a top ring groove 26 for guiding the crossbar 21 to rotate upon impact is opened on the upper surface of the support plate 25, and an auxiliary moving block 212 is provided in the top ring groove 26. A groove 29 is provided on one side of the lower part of the plate, and a buffer plate 210 is provided inside the groove 29. A set of guide rods 214 for guiding impact displacement is provided on each side of the buffer plate 210, and a buffer spring 215 for impact buffering is sleeved on the outside of the guide rods 214. The adjusting assembly 3 includes a vertical frame 27, in which a threaded screw 31 is installed.

Below the threaded screw 31 is a circular seat 28 that can rotatably adjust the position of the ultrasonic level gauge 1. When the ultrasonic level gauge 1 is working, its transducer emits ultrasonic pulses, which are reflected by the water surface and received by the transducer. The connected instrument measures the time difference between emission and reception, and, combined with the speed of ultrasonic waves in air, calculates the distance from the transducer to the water surface, thereby achieving real-time water level monitoring.

[0025] Please see Figure 1 , Figure 2 as well as Figure 4As shown, the auxiliary block 212 is fixedly connected to the crossbar 21, and the ultrasonic water level gauge 1 is installed on the front side of the crossbar 21. Multiple sets of compression springs 23 are provided and are evenly distributed between the crossbar 21 and the I-shaped slider 32.

[0026] Please see Figures 1-2 As shown, the threaded screw 31 is installed inside the upright frame 27, and the drive motor 33 is installed above the upright frame 27. The output shaft of the drive motor 33 is fixedly connected to the threaded screw 31.

[0027] Please see Figure 1 , Figure 2 as well as Figure 4 As shown, a connecting rod 24 is installed on the side of the I-shaped slider 32 near the crossbar 21. The crossbar 21 is fixedly connected to the connecting rod 24 by a compression spring 23. The front end of the support plate 25 is a circular structure, and its rear end is fixedly connected to the connecting rod 24.

[0028] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 6 As shown, the plate groove 29 is formed on the upper surface of the round seat 28. A set of guide grooves 211 are formed on the front and rear sides of the plate groove 29. An inner slider 213 is slidably arranged in each of the two sets of guide grooves 211. The guide rod 214 is located in the guide groove 211. The inner slider 213 is fixedly connected to the front end of the guide rod 214. The rear end of the guide rod 214 passes through the plate groove 29 and is connected to the limit block 216. The front end of the buffer spring 215 is connected to the inner slider 213, and its rear end is fixedly connected to the inner wall of the guide groove 211. The design of the limit block 216 can limit the forward movement of the guide rod 214 and prevent the buffer spring 215 from rebounding excessively.

[0029] Please see Figures 1-3 As shown, a base 34 is provided below the circular seat 28, and a set of mounting holes 35 are provided around the base 34. A circular groove is provided inside the base 34, and the circular seat 28 is located in the circular groove. A rotary motor 36 is installed below the inside of the circular groove, and the output shaft of the rotary motor 36 is fixedly connected to the circular seat 28.

[0030] Please see Figure 1 , Figure 5 as well as Figure 6 As shown, a bottom ring groove 37 is provided above the inside of the circular groove. Multiple sets of limiting sliders 38 are equidistantly arranged in a ring shape inside the bottom ring groove 37, and the limiting sliders 38 are fixedly connected to the circular seat 28.

[0031] In practical use, the working principle of this utility model is as follows:

[0032] Before it is put into use, the staff can pass the bolts through the mounting holes 35 on the device base 34 and make a firm connection with the selected installation position to complete the fixing operation of the entire device and ensure that the device is installed firmly. The ultrasonic water level gauge 1 will monitor the water level changes in real time. When the ship accidentally scrapes against the device during the journey, the movement of the ship will drive the pulley 22 installed at the front end of the crossbar 21 to rotate. With its flexible rotation characteristics, the pulley 22 changes the direction of the force generated by the ship scraping, and transforms the scraping force that may have damaged the device into the power of the pulley 22 to rotate, thereby effectively avoiding damage to the device due to hard scraping.

[0033] If the ship accidentally hits the side of the crossbar 21, the crossbar 21 will be the first to bear the impact force. The pressure generated by the collision will push the crossbar 21 to rotate, causing the four sets of compression springs 23 set at equal intervals behind it to bend and deform. During the deformation process, these compression springs 23 effectively absorb the impact force and buffer the energy generated by the collision. At the same time, when the crossbar 21 rotates, it will drive the auxiliary block 212 fixedly connected to it to rotate synchronously in the top ring groove 26 on the upper surface of the support plate 25, ensuring that the position of the crossbar 21 will not easily shift after being hit.

[0034] If the collision direction of the ship is directly in front of the horizontal position of the crossbar 21, when the straight-line collision extrusion force comes, the pressure on the crossbar 21 will be transmitted to the support plate 25 through the auxiliary block 212. The support plate 25 will then transmit the pressure to the connecting rod 24. The connecting rod 24 will then transmit the extrusion force to the vertical frame 27 through the I-beam slider 32. Finally, the pressure will be transmitted to the buffer plate 210. At this time, the extrusion force will cause the buffer plate 210 in the plate groove 29 to drive the inner slider 213 to slide along the path set by the guide groove 211. At the same time, it will apply pressure to the guide rod 214. Under the guidance of the guide rods 214 on both sides, the guide rod 214 will slide along the through-hole. The buffer spring 215 on the outside of the guide rod 214 will be compressed. The buffer spring 215 will release the extrusion force during the compression process, reducing the risk of damage to the device due to straight-line extrusion.

[0035] Since the crossbar 21 is usually placed horizontally on one side of the waterway surface for real-time water level monitoring via the ultrasonic level gauge 1, when the crossbar 21 may obstruct the passage of large vessels in a narrow waterway, the rotary motor 36 is activated. The rotary motor 36 drives the circular seat 28 connected to the output shaft to rotate. During the rotation of the circular seat 28, the crossbar 21 will rotate away from the waterway, effectively avoiding interference with the vessel's movement. Inside the bottom ring groove 37 above the circular groove, the limiting sliders 38, which are distributed in a ring at equal intervals and fixedly connected to the circular seat 28, will slide along the bottom ring groove 37 when the circular seat 28 rotates, thus limiting the rotation of the circular seat 28 and ensuring its stable rotation. Furthermore, if the ultrasonic level gauge 1 is impacted... The position can be adjusted by combining the above rotation operation. If the ultrasonic level gauge 1 needs to be maintained or repaired, the crossbar 21 can be rotated away from the waterway by rotating motor 36, and then the drive motor 33 above the frame 27 can be started. The drive motor 33 drives the threaded screw 31 connected to the output shaft to rotate. The I-shaped slider 32, which is threaded to the threaded screw 31, will slide and rise along the inner side of the frame 27. Since the I-shaped slider 32 is connected to the crossbar 21 through the connecting rod 24, the rise and fall of the I-shaped slider 32 can drive the crossbar 21 and the ultrasonic level gauge 1 installed in front of the crossbar 21 to descend, which is convenient for the staff to carry out maintenance work and improves the convenience of device maintenance.
