Description

Technical Field

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

[0002] Currently, ultrasonic sensors are commonly used in water conservancy projects to monitor water levels. The ultrasonic sensor emits ultrasonic waves towards the water surface. During the propagation process, the ultrasonic waves are reflected when they encounter the water surface. The sensor receives the reflected echoes. By calculating the time interval between the emission and reception of the ultrasonic waves and combining it with the speed of ultrasonic wave propagation in the air, the distance between the sensor and the water surface can be calculated, and thus the water level can be obtained. Due to its non-contact measurement and strong anti-interference ability, ultrasonic sensors are widely used in water level monitoring.

[0003] However, ultrasonic sensor probes are exposed to the outdoor environment for a long time, and their surfaces are easily contaminated with dust, moisture and other debris, which leads to a decrease in ultrasonic transmission and reception efficiency. Usually, staff need to climb up regularly to clean them, and the interval between each cleaning is very long, which affects the normal use of ultrasonic sensor probes. In addition, each cleaning is not only time-consuming, but also poses a risk of falling from a height. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a water level monitoring device for water conservancy projects.

[0005] This utility model is achieved using the following technical solution: a water level monitoring device for water conservancy projects, comprising an L-shaped support frame, an ultrasonic sensor assembly for monitoring water level fixedly installed at one end of the support frame, a cleaning component capable of automatically cleaning the surface of the ultrasonic sensor assembly on one side of the ultrasonic sensor assembly, a limiting component capable of preventing the cleaning component from obstructing the ultrasonic sensor assembly on one side of the cleaning component, the cleaning component comprising a rotating rod disposed on the support frame, the bottom end of the rotating rod penetrating downward through the support frame and fixedly mounted on an mounting plate, a plurality of soft brushes arranged in an array fixedly mounted on the top of the mounting plate, and a plurality of connecting rods arranged in a circular array fixedly mounted on the top of the rotating rod, each connecting rod being fixedly mounted with a fan blade.

[0006] With the above technical solution, when water or air flows over the fan blades, the fan blades will drive the rotating rod to rotate, thereby causing the soft brush on the mounting plate to clean the surface of the ultrasonic sensor assembly, achieving automatic cleaning without manual operation, ensuring the cleanliness of the ultrasonic sensor assembly surface, and improving the accuracy of water level monitoring.

[0007] As a further improvement to the above solution, two limiting plates are fixedly sleeved on the rotating rod, and the opposing surfaces of the two limiting plates are in contact with the surface of the support frame. A pressing rod is fixedly installed on one side of the rotating rod.

[0008] Through the above technical solution, the limiting plate can restrict the vertical movement of the rotating rod on the support frame, ensuring the stable rotation of the rotating rod.

[0009] As a further improvement to the above solution, the limiting component includes support plates disposed on both sides of the top of the ultrasonic sensor assembly. Both support plates are fixedly installed with the support frame. Each of the two support plates has a sliding groove on its top. Each of the two sliding grooves has a sliding block slidably installed inside. Each of the two sliding blocks has a connecting plate fixedly installed on its top. Each of the two connecting plates has a limiting plate rotatably installed on its top. The two limiting plates rotate in coordination.

[0010] Through the above technical solution, the limiting component can restrict the cleaning component when it is not working, preventing the cleaning component from blocking the ultrasonic sensor component, ensuring that the ultrasonic sensor component can normally transmit and receive ultrasonic waves, and ensuring the accuracy of water level monitoring.

[0011] As a further improvement to the above solution, the top of the support frame is provided with a sliding hole, a top rod is slidably inserted into the sliding hole, a top plate is fixedly installed on the top of the top rod, the top of the top plate is in contact with two limiting plates, a spring is sleeved on the top rod, and the two ends of the spring are fixedly installed to the top plate and the support frame respectively.

[0012] Through the above technical solution, the spring allows the top plate to apply a certain pressure to the limiting plate, ensuring that the limiting plate stably restricts the cleaning component and prevents the cleaning component from accidentally moving and obstructing the ultrasonic sensor component when not in a cleaning state. During cleaning, each rotation of the rotating rod causes the squeezing rod to press the limiting plate downwards, which in turn pushes the top plate downwards, compressing the spring. This allows the squeezing rod to pass through, enabling the rotating rod to rotate normally and allowing the soft brush to clean the ultrasonic sensor component.

[0013] As a further improvement to the above solution, a cover plate for blocking the sliding groove is fixedly installed on one side of each of the two sliding blocks, and both cover plates are slidably engaged with the support plate.

[0014] Through the above technical solution, the cover plate can prevent dust, moisture and other debris from entering the sliding groove, avoid the sliding block in the sliding groove from getting stuck due to debris accumulation, ensure the normal sliding and rotation of the limiting component, and extend the service life of the device.

[0015] As a further improvement to the above solution, a plurality of dust removal plates are provided on one side of the rotating rod, and the top of each dust removal plate is fixedly installed with the support frame.

[0016] With the above technical solution, during the rotation of the rotating rod, the cleaning part of the soft brush will hit the dust removal plate, which can make the dust on the soft brush fall off and prevent the soft brush from being contaminated with too much dust.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention achieves automatic cleaning of the ultrasonic sensor assembly by setting up a cleaning component and a limiting component, eliminating the need for manual operation, ensuring the cleanliness of the ultrasonic sensor assembly surface, and improving the accuracy of water level monitoring; at the same time, the limiting component can prevent the cleaning component from obstructing the ultrasonic sensor assembly when it is not clean, ensuring the normal operation of water level monitoring.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] Please combine Figures 1-4This embodiment of a water level monitoring device for water conservancy projects includes an "L"-shaped support frame 1. An ultrasonic sensor assembly 2 for monitoring water level is fixedly installed at one end of the support frame 1. A cleaning component capable of automatically cleaning the surface of the ultrasonic sensor assembly 2 is provided on one side of the ultrasonic sensor assembly 2. A limiting component capable of preventing the cleaning component from obstructing the ultrasonic sensor assembly 2 is provided on one side of the cleaning component.

[0027] The cleaning assembly includes a rotating rod 301 mounted on a support frame 1. The bottom end of the rotating rod 301 extends downward through the support frame 1 and is fixedly mounted on a mounting plate 302. Multiple soft brushes 303 arranged in an array are fixedly mounted on the top of the mounting plate 302. Multiple connecting rods 304 arranged in a ring array are fixedly mounted on the top of the rotating rod 301. Each connecting rod 304 is fixedly mounted with a fan blade 305. Two limiting pieces 5 are fixedly sleeved on the rotating rod 301. The opposing surfaces of the two limiting pieces 5 are in contact with the surface of the support frame 1. A squeezing rod 11 is fixedly mounted on one side of the rotating rod 301.

[0028] When water or air flows over the fan blade 305, the fan blade 305 will drive the rotating rod 301 to rotate, which in turn causes the soft brush 303 on the mounting plate 302 to clean the surface of the ultrasonic sensor assembly 2, achieving automatic cleaning without manual operation, ensuring the cleanliness of the surface of the ultrasonic sensor assembly 2 and improving the accuracy of water level monitoring.

[0029] The limiting piece 5 can restrict the vertical movement of the rotating rod 301 on the support frame 1, ensuring that the rotating rod 301 rotates stably.

[0030] The limiting component includes support plates 401 disposed on both sides of the top of the ultrasonic sensor assembly 2. Both support plates 401 are fixedly installed with the support frame 1. Each of the tops of the two support plates 401 is provided with a sliding groove. Sliding blocks 402 are slidably installed inside each of the two sliding grooves. Connecting plates 403 are fixedly installed on the tops of each of the two sliding blocks 402. Limiting plates 404 are rotatably installed on the tops of each of the two connecting plates 403. The two limiting plates 404 are rotatably engaged.

[0031] The limiting component can restrict the cleaning component when it is not working, preventing it from blocking the ultrasonic sensor component 2, ensuring that the ultrasonic sensor component 2 can normally transmit and receive ultrasonic waves, and ensuring the accuracy of water level monitoring.

[0032] The top of the support frame 1 has a sliding hole, into which a top rod 6 is slidably inserted. A top plate 7 is fixedly installed on the top of the top rod 6, and the top of the top plate 7 is in contact with two limiting plates 404. A spring 8 is sleeved on the top rod 6, and both ends of the spring 8 are fixedly installed to the top plate 7 and the support frame 1, respectively. The spring 8 allows the top plate 7 to apply a certain pressure to the limiting plate 404, ensuring that the limiting plate 404 stably restricts the cleaning component and prevents the cleaning component from accidentally moving and obstructing the ultrasonic sensor component 2 when not cleaning. During cleaning, each rotation of the rotating rod 301 causes the squeezing rod 11 to squeeze the limiting plate 404 downward. The limiting plate 404 pushes the top plate 7 downward, compressing the spring 8. The limiting plate 404 then allows the squeezing rod 11 to pass through, thus allowing the rotating rod 301 to rotate normally and the soft brush 303 to clean the ultrasonic sensor component 2.

[0033] Each of the two sliding blocks 402 has a cover plate 9 fixedly installed on one side to cover the sliding groove, and both cover plates 9 are slidably engaged with the support plate 401.

[0034] The cover plate 9 can prevent dust, moisture and other debris from entering the sliding groove, avoid the sliding block 402 in the sliding groove from getting stuck due to debris accumulation, ensure the normal sliding and rotation of the limiting component, and extend the service life of the device.

[0035] Multiple cleaning plates 10 are provided on one side of the rotating rod 301, and the top of each cleaning plate 10 is fixedly installed with the support frame 1.

[0036] During the rotation of the rotating rod 301, the cleaning part of the soft brush 303 will hit the dust removal plate 10, which can make the dust on the soft brush 303 fall off and prevent the soft brush 303 from being covered with too much dust.

[0037] The implementation principle of a water level monitoring device for water conservancy projects in this application embodiment is as follows: when water or air flows through the fan blade 305, the fan blade 305 drives the rotating rod 301 to rotate. The rotating rod 301 rotates stably on the support frame 1 through the limiting piece 5, and the soft brush 303 on the mounting plate 302 rotates accordingly.

[0038] The rotation of the rotating rod 301 also causes the pressing rod 11 to move, thereby pressing the limiting plate 404 downward. The downward movement of the limiting plate 404 pushes the top plate 7 downward, and the compression spring 8 reduces the height of the entire limiting plate 404. In this way, the pressing rod 11 will pass over the top of the limiting plate 404, and the rotating rod 301 can rotate normally for one revolution. It will not be restricted from rotating because the pressing rod 11 cannot push the limiting plate 404. When the rotating rod 301 rotates, the soft brush 303 can clean the ultrasonic sensor assembly 2.

[0039] Each rotation of the rotating rod 301 requires sufficient airflow to allow the squeezing rod 11 to press and push the limiting plate 404. Otherwise, if the squeezing rod 11 cannot push the limiting plate 404, the rotating rod 301 will not be able to rotate a full circle properly because the limiting plate 404 blocks the squeezing rod 11, and the soft brush 303 will not be able to clean.

[0040] Furthermore, during the rotation of the rotating rod 301, the cleaning part of the soft brush 303 will hit the dust removal plate 10, which will cause the dust on the soft brush 303 to fall off, thus preventing the soft brush 303 from being contaminated with too much dust and impurities.

[0041] When there is insufficient wind or no wind, the spring 8 pushes the top plate 7 upward, so that the top plate 7 fits against the two limiting plates 404. After the limiting plates 404 are pushed up, the top will form a sharp corner. If the squeezing rod 11 is above the limiting plate 404 at this time, it will be pushed to one side by the lifted limiting plate 404. In this way, the rotating rod 301 will also be rotated, so that the soft brush 303 will not stop directly below the ultrasonic sensor assembly 2, thus avoiding affecting its monitoring of the water level.

[0042] The sliding block 402 slides in the sliding groove of the support plate 401, driving the connecting plate 403 and the limiting plate 404 to move. The cover plate 9 slides with the sliding block 402, blocking the sliding groove and preventing debris from entering.

[0043] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
