Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, specifically to a photoelectric sediment height monitoring device. Background Technology

[0002] In fields such as hydrological monitoring, accurate monitoring of sediment height is crucial. Traditional manual measurement methods are inefficient and highly dependent on environmental conditions, while automated monitoring technologies such as ultrasonic and pressure sensors also have many shortcomings. For example, ultrasonic sensors are easily affected by water bubbles and turbidity, and pressure sensors are prone to clogging by sediment. Although photoelectric monitoring technology has applications, existing devices are complex in structure, have poor adaptability, and are difficult to adapt to different water depths and sediment particle sizes, and their anti-interference capabilities are weak. Therefore, developing a photoelectric sediment height monitoring device with a simple structure, strong anti-interference capabilities, and accurate measurement is of significant practical importance.

[0003] However, existing traditional monitoring methods mostly rely on manual sampling and ruler measurement, which require on-site operation by personnel, resulting in low efficiency, time and labor consumption. Furthermore, they are difficult to implement in deep water, turbulent water flow, or harsh environments, and the data timeliness and continuity are poor. Additionally, the control structure is inconvenient to install. Therefore, those skilled in the art provide a photoelectric sediment height monitoring device to solve the problems mentioned in the background art. Utility Model Content

[0005] This utility model provides the following technical solution: a photoelectric sediment height monitoring device includes a control structure for connecting a detection device, wherein the bottom end of the control structure is electrically connected to a detection device for sensing.

[0006] As a preferred embodiment of the above technical solution, the detection structure includes a frame, with multiple diode transmitters fixedly connected to one side of the inner wall of the frame, a receiver fixedly installed on the other side of the inner wall of the frame, and connecting wires electrically connected to both ends of the bottom of the frame.

[0010] As a preferred embodiment of the above technical solution, the connecting block is located between the support frame and the fixing plate.

[0011] As a preferred embodiment of the above technical solution, the control structure is located behind the detection structure.

Combined with coding recognition and point-by-point detection, it can directly correspond to the height of mud and sand cover, achieving centimeter-level accurate measurement.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] Please see Figure 1 As shown, this utility model provides a technical solution: a photoelectric sediment height monitoring device includes a control structure 1 for connecting detection data, and a detection structure 2 for sensing is electrically connected to the bottom end of the control structure 1.

[0018] The device is divided into two main core parts: control structure 1 and detection structure 2. Control structure 1 integrates signal processing and power management units, and is responsible for processing the raw signals from detection structure 2 and converting them into readable height data. It extends directly into the environment under test and senses changes in the sediment interface in real time through optical principles. The two are electrically connected to form a complete automated monitoring system, realizing the entire process from data acquisition, processing to output.

[0019] As one implementation method in this embodiment, please refer to Figure 1 and Figure 2 As shown, the detection structure 2 includes a frame 21. Multiple diode transmitters 23 are fixedly connected to one side of the inner wall of the frame 21, and a receiver 22 is fixedly installed on the other side of the inner wall of the frame 21. Connecting wires 24 are electrically connected to both ends of the bottom of the frame 21.

[0020] The core of the detection structure 2 is a slender frame 21. Its innovation lies in the fact that multiple infrared or laser diode emitters 23 are vertically arranged at 1-centimeter intervals on one inner wall of the frame 21, forming a linear optical signal emission array. On the opposite inner wall of the frame 21, high-sensitivity receivers 22 are installed. This through-beam arrangement enables coded identification and point-by-point detection: when the silt is not covering the area, the light emitted by all diode emitters 23 can be normally received by the receiver 22 on the opposite side; as the silt gradually rises, it will sequentially block the light path of diode emitters 23 at specific positions from bottom to top, causing a jump in the signal strength of the corresponding receiver 22. This change is transmitted in real time to the control structure 1 via the connecting line 24 at the bottom of the frame 21, thus directly and accurately corresponding to the silt coverage height, achieving centimeter-level precision measurement.

[0021] As one implementation method in this embodiment, please refer to Figure 1 , Figure 3 and Figure 4As shown, the control structure 1 includes a housing 11, a support frame 15 fixedly connected to the rear side of the housing 11, a sliding groove 110 opened around the support frame 15, a connecting block 13 provided on the inner wall of the support frame 15, springs 19 fixedly connected to both ends of the connecting block 13, a pressing post 111 fixedly connected to one end of each of the two springs 19, hollow posts 18 fixedly connected to both ends of the connecting block 13, the two hollow posts 18 sleeved on the outside of the two springs 19, the two pressing posts 111 slidably connected inside the hollow posts 18, limit posts 17 fixedly connected to both sides of the two pressing posts 111, the four limit posts 17 slidably connected inside the four sliding grooves 110, and a fixing plate 14 fixedly connected to one side of the connecting block 13.

[0022] The mechanical core of control structure 1 is a precision quick-release mechanism consisting of a pressing post 111, a spring 19, a limiting post 17, and a sliding groove 110. The structure inside the housing 11 is responsible for the initial processing, conversion, and output of signals. The support frame 15 and the fixing plate 14 provide a stable mounting base for the entire quick-release mechanism. In its natural state, the spring 19 provides outward elastic force to the pressing post 111, ensuring that it is in a stable connection position. The cooperation between the limiting post 17 and the sliding groove 110 strictly limits the sliding trajectory and stroke of the pressing post 111, preventing it from deflecting or excessively displacing during operation, thus ensuring the reliability and consistency of the quick-release action.

[0023] As one implementation method in this embodiment, please refer to Figure 3 and Figure 4 As shown, one end of each of the two pressing columns 111 is fixedly connected to a pressing block 16, and a handle 12 is fixedly connected to the front side of the housing 11.

[0024] The pressing block 16 serves as the human-machine interface for the quick-release mechanism. Its design allows users to simultaneously drive the pressing posts 111 on both sides with a simple one-handed pressing action. The handle 12 on the front of the housing 11 not only facilitates the carrying and deployment of the entire device, but more importantly, when installing or disassembling the detection structure 2, the operator can hold the handle 12 with one hand to stabilize the housing 11 while operating the pressing block 16 with the other hand. This makes the assembly and disassembly process safer and less strenuous, especially suitable for operation in field or complex environments. As one implementation method in this embodiment, please refer to Figures 1-4 As shown, two connecting wires 24 are electrically connected to the bottom of the pressing post 111.

[0025] The connecting wire 24 of the detection structure 2 is reliably plugged into the bottom of the pressing post 111 via an electrical connection. This design is key to enabling quick assembly and disassembly: under the push of the spring 19, the pressing post 111 maintains tight contact with the connecting wire 24, ensuring stable transmission of data signals and power supply; when separation is required, pressing the pressing block 16 retracts the pressing post 111, easily disconnecting the connection. This connection method requires no tools, improving the efficiency of installation, maintenance, and replacement of the detection structure 2. As one implementation method in this embodiment, please refer to Figure 3 and Figure 4 As shown, the connecting block 13 is located between the support frame 15 and the fixing plate 14.

[0026] The connecting block 13 is securely constrained between the support frame 15 and the fixing plate 14. This structure ensures that the force on all moving parts in the quick-release mechanism can be effectively transmitted to the main structure of the housing 11, thereby guaranteeing the structural strength and long-term stability of the entire mechanism under repeated use. As one implementation method in this embodiment, please refer to Figure 3 and Figure 4 As shown, control structure 1 is located behind detection structure 2.

[0027] The control structure 1 is located above and behind the detection structure 2. This layout has two advantages: first, it physically separates the core electronic control components from the detection and sensing parts that directly contact the mud and water, placing the control structure 1 in a relatively safer and drier environment, effectively improving the protection level and reliability of the device; second, it creates a reasonable center of gravity distribution, making the device more stable after installation and less prone to tipping over due to water flow or external forces.

[0028] Working principle: Within the frame 21 of the detection structure 2, multiple diode emitters 23 on one side emit light signals, and receivers 22 on the other side receive the light signals. When the sediment rises to different heights, it blocks the light emitted by the corresponding diode emitters 23, causing changes in the intensity of the light signal received by the receiver 22. This reflects the height of the sediment. The detected changes in the light signal are transmitted through the connecting line 24 at the bottom of the frame 21 to the pressing post 111 of the control structure 1, and then to the control components inside the housing 11 to complete the initial processing and conversion of the signal.

[0029] When it is necessary to disassemble the detection structure 2, press the pressing block 16. The pressing block 16 drives the pressing column 111 to slide into the hollow column 18, compressing the spring 19. At the same time, the limiting column 17 slides synchronously in the slide groove 110. As the pressing column 111 slides, the connection between it and the connecting line 24 of the detection structure 2 gradually separates. When the pressing column 111 slides to a certain extent, the connecting line 24 is completely separated from the pressing column 111, and the detection structure 2 can be removed, completing the quick-release operation. During installation, align the connecting line 24 of the detection structure 2 with the bottom end of the pressing column 111, then release the pressing block 16. The spring 19 returns to its original state, pushing the pressing column 111 to slide outward, so that the pressing column 111 and the connecting line 24 are reconnected. The limiting column 17 also returns to its initial position in the slide groove 110, completing the process.

[0030] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
