Description

Technical Field

[0001] This application relates to the field of river measurement equipment technology, and in particular to a shore-based river depth measurement device. Background Technology

[0002] Accurate measurement of river depth is crucial in numerous fields, including water conservancy projects, river ecological environment monitoring, and water transport safety. Currently, traditional methods and equipment for measuring water depth have many limitations. For example, direct measurement using a sounding rod requires personnel to work in the water. This is not only difficult to operate in situations with rapid currents, deep water, or complex aquatic environments (such as the presence of abundant aquatic plants or underwater obstacles), but also poses a significant threat to the personal safety of the personnel.

[0003] In existing technologies, water depth measurement is mainly achieved through the following methods: Manual handheld measurement: The surveyor stands on the shore or wades in the water, holding a sounding rod or rope. Advantages include simple equipment and low cost; disadvantages include poor measurement stability, significant influence from human factors, and safety hazards. Echo sounder: Utilizes the principle of sound wave reflection to measure water depth. It offers high accuracy and is suitable for large-area water measurement. Advantages include fast measurement speed and high accuracy; disadvantages include expensive equipment, requiring professional operation and maintenance, and unsuitability for shallow or narrow waters. Buoy measurement: Measurement is performed using a combination of a buoy and a sounding rope. Advantages include simple equipment; disadvantages include low measurement efficiency, significant influence from water flow, and inability to precisely control the measurement position.

[0004] Regarding the aforementioned technologies, traditional surveying methods suffer from problems such as unstable handheld operation by personnel standing on the shore or the need to place the equipment in the water. Furthermore, the use of specialized surveying equipment is costly and complex to operate, resulting in poor portability and difficulty in flexibly covering measurement points at different distances. Summary of the Invention

[0005] To address the problems of dangerous operations for surveyors, high equipment costs, complex operation, and poor portability in existing technologies, this application provides a shore-based river depth measurement device.

[0006] This application provides a shore-based river depth measurement device, which adopts the following technical solution:

[0007] A bank-based river depth measurement device includes a bank-based support assembly for supporting the device and a reading display assembly for measuring water depth. The support assembly is equipped with a telescopic assembly, and the telescopic assembly is equipped with a line-laying reel and a measuring assembly for measuring water depth. The measuring assembly is mounted on the line-laying reel and is equipped with a measuring probe assembly for bottom detection. The measuring probe assembly and the reading display assembly communicate wirelessly.

[0008] By adopting the above technical solution, the device is directly fixed to the shore using a shore-based support component, avoiding the problems of unstable handheld operation or the need to place the equipment in the water, which are common in traditional surveying methods. The telescopic component can adjust the length of the measuring arm, and the measuring component can be released in conjunction with the line-laying reel, flexibly covering measuring points at different distances from the shore to the river channel. There is no need to frequently move the entire device, and the operation logic is simple and easy to learn, like fishing. At the same time, the overall structure is similar to a fishing rod assembly and can be designed to be detachable and foldable (such as retracting the telescopic component and storing the line-laying reel), making it easy to carry and transport. Compared with professional measuring equipment such as echo sounders, the device structure of this utility model is relatively simple, the materials and components used are of lower cost, and no professional maintenance and calibration are required, which greatly reduces the measurement cost.

[0009] Preferably, the shore support assembly includes a height-adjustable tripod and a mounting base for securing the telescopic assembly, the mounting base being mounted on top of the tripod.

[0010] By adopting the above technical solution, the tripod distributes the weight of the device (including the telescopic component, the line reel, and the overall load of the measuring component) through three-point support. Compared with single-pole support and bipedal support, it can effectively resist the impact of wind and water flow on the riverbank (such as the lateral force caused by the rotation of the line reel and the extension of the telescopic component during measurement), prevent the device from tilting or swaying, ensure that the measuring component is lowered vertically in the water, and at the same time, the fixed base can stably fix and support the telescopic component to prevent the telescopic component from swaying during measurement.

[0011] Preferably, the tripod's support legs are provided with multiple adjustment holes, and the tripod's support legs are provided with pins for adjusting the length of the tripod's support legs, the pins being located within the adjustment holes.

[0012] By adopting the above technical solution, the height of the tripod can be easily adjusted by adjusting the position of the pin in different adjustment holes to adapt to the measurement needs of different terrains.

[0013] Preferably, the telescopic assembly includes multiple connecting rods, all of which are conical in shape, and the diameters of the multiple connecting rods are different, and the multiple connecting rods are sleeved together.

[0014] By adopting the above technical solution, multiple connecting rods use a nested design of "large inside small" so that they can be completely retracted when stored (e.g., the longest section can accommodate all the short sections). The overall size is small and the weight is light (compared to a fixed long rod that cannot be extended), which reduces the load on the tripod (avoiding instability) and makes it easy to carry and move. At the same time, the conical column shape (i.e., a conical columnar structure that is slightly thicker at one end and slightly thinner at the other end) is combined with "nested connection with different diameters". When the connecting rod is stretched to the target length, the inner wall of the thicker connecting rod will naturally fit with the outer wall of the thinner connecting rod, forming a self-locking effect that "gets tighter under pressure".

[0015] Preferably, the measuring assembly includes a high-strength and wear-resistant measuring line and a plurality of markers mounted on the measuring line. The measuring line is wound on a feed reel, and the markers are mounted on the measuring line at equal intervals. Each marker is provided with a unique color or mark.

[0016] By adopting the above technical solution and using high-strength measuring lines (such as nylon or Kevlar fiber), the measuring probe components (such as sensors and counterweights) can withstand their weight and are not easily broken by pulling during the deployment or retrieval process. Even if there are minor underwater debris (such as aquatic plants or pebbles), the risk of "loss of the detection components due to line breakage" after being snagged is reduced, thus improving the device's anti-interference capability. At the same time, the markers are installed at equal intervals, which is equivalent to transforming the measuring lines into a visual ruler so that the measuring personnel can clearly distinguish them when reading the data.

[0017] Preferably, the connecting rod is provided with a guide ring for guiding the measuring line, and the measuring line is located inside the guide ring.

[0018] By adopting the above technical solution, the guide ring can guide the measurement line. The guide ring fixes the line in a preset path (such as a direction perpendicular to the water surface) through physical limiting, forcing the line to be lowered in a straight line, thereby reducing measurement errors caused by deviation at the source. At the same time, by making the inner wall of the guide ring generally smooth (such as a metal ring or a plastic ring), the hard contact between the line and the connecting rod can be transformed into smooth sliding between the line and the inner wall of the ring, which greatly reduces wear, avoids blurred markings or sudden breakage due to line wear, and reduces the replacement frequency.

[0019] Preferably, the measuring probe assembly includes a pressure sensor, a signal transmitter, and a counterweight for the measuring probe assembly to contact the bottom. The counterweight is mounted on the surface of the pressure sensor, the top of the pressure sensor is connected to the signal transmitter, the signal transmitter is connected to the end of the measuring rope, and the pressure sensor is electrically connected to the signal transmitter.

[0020] By adopting the above technical solution, the signal transmitter (such as a wireless radio frequency, Bluetooth, or wired transmission module) can convert the electrical signal of the pressure sensor into identifiable data (such as wirelessly transmitting it to a receiver on the shore, or conducting it through a wire). Operators can obtain water depth data in real time without retrieving the measuring rope. At the same time, by setting up a pressure sensor, the water depth can be inferred by the water pressure change after the pressure sensor touches the bottom. After the pressure sensor touches the bottom, it will be located in the bottom silt. The thickness of the bottom silt can be observed by the pressure difference change when the pressure sensor touches the bottom.

[0021] Preferably, the reading display assembly includes a housing, a signal receiver, a microprocessor, and a display screen. The signal receiver, microprocessor, and display screen are all mounted on the housing. The signal receiver is wirelessly connected to the signal transmitter. The microprocessor is electrically connected to the signal receiver. The display screen is electrically connected to the microprocessor.

[0022] By adopting the above technical solution, the signal receiver and signal transmitter communicate wirelessly to receive electrical signals sent by the measuring probe assembly. The microprocessor is electrically connected to the signal receiver and can process and calculate the received electrical signals. Based on the conversion relationship between water pressure and water depth, the water depth data of the measuring point is obtained. The display screen is electrically connected to the microprocessor to intuitively display the water depth data for easy reading by the measuring personnel.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By fixing the device directly to the shore using a shore-based support assembly, the problems of unstable handheld measurement or needing to go into the water to place the equipment, which are common in traditional measurements, are avoided. The telescopic assembly can adjust the length of the measuring arm, and the measuring assembly can be released in conjunction with the line reel, which can flexibly cover measuring points at different distances from the shore to the river channel. There is no need to frequently move the entire device. The operation logic is simple and easy to learn, like fishing. At the same time, the overall structure is similar to a fishing rod assembly and can be designed to be detachable and foldable (such as retracting the telescopic assembly and storing the line reel), making it easy to carry and transport. Compared with professional measuring equipment such as echo sounders, the device structure of this utility model is relatively simple, the materials and components used are of lower cost, and no professional maintenance and calibration are required, which greatly reduces the measurement cost.

[0025] 2. The tripod distributes the weight of the device (including the telescopic assembly, the line reel, and the overall load of the measuring component) through three-point support. Compared with single-pole support and bipedal support, it can effectively resist the impact of wind and water flow on the riverbank (such as the lateral force caused by the rotation of the line reel and the extension of the telescopic assembly during measurement), prevent the device from tilting or swaying, and ensure that the measuring component is lowered vertically in the water. At the same time, the fixed base can stably support the telescopic assembly and prevent the telescopic assembly from swaying during measurement.

[0026] 3. Multiple connecting rods adopt a nested design of "large nesting small", which can be completely retracted when stored. The overall size is small and the weight is light, which reduces the load pressure on the tripod and makes it easy to carry and move. At the same time, the conical shape is combined with "interlocking connection with different diameters". When the connecting rod is stretched to the target length, the inner wall of the thicker connecting rod will naturally fit with the outer wall of the thinner connecting rod, forming a self-locking effect of "the tighter the force, the tighter".

Detailed Implementation

[0034] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 This application will be described in further detail.

[0035] This application discloses a shore-based river depth measurement device.

[0036] Reference Figure 1 and Figure 2A shore-based river depth measurement device includes a shore-based support assembly 100 for supporting the device, a reading display assembly 200 for measuring depth, a telescopic assembly 300, a line-laying reel 400, a measuring assembly 500 for measuring depth, and a measuring probe assembly 600 for bottom detection. The telescopic assembly 300 is fixedly mounted on the shore-based support assembly 100, the line-laying reel 400 is rotatably mounted on the telescopic assembly 300, the measuring assembly 500 is mounted on the line-laying reel 400 so that the line-laying reel 400 positions and measures the measuring assembly 500, and the measuring probe assembly 600 is mounted on the end of the measuring assembly 500 so that the measuring probe assembly 600 can move and detect depths with the measuring assembly 500. The measuring probe assembly 600 is connected to the reading display assembly 100. The display component 200 communicates wirelessly; it is directly fixed to the shore via the shore-based support component 100, avoiding the problems of unstable handheld operation or needing to go into the water to place the equipment in traditional measurements. The telescopic component 300 can adjust the length of the measuring arm, and the measuring component 500 can be released in conjunction with the line-laying reel 400, which can flexibly cover measuring points at different distances from the shore to the river channel without frequent movement of the entire device. The operation logic is simple and easy to learn, like fishing. At the same time, the overall structure is similar to a fishing rod assembly and can be designed to be detachable and foldable for easy carrying and transportation. Compared with professional measuring equipment such as echo sounders, the device structure of this utility model is relatively simple, the materials and components used are of lower cost, and no professional maintenance and calibration are required, which greatly reduces the measurement cost.

[0037] refer to Figure 3 and Figure 4 The shore-based support assembly 100 includes a height-adjustable tripod 110 and a fixing base 120 for fixing the telescopic assembly 300. The fixing base 120 is mounted on the top of the tripod 110. Multiple adjustment holes 111 are provided on the support legs of the tripod 110, and pins 112 for adjusting the length of the support legs are provided on the support legs of the tripod 110. The pins 112 are located within the adjustment holes 111. The weight of the device (including the overall load of the telescopic assembly 300, the line reel 400, and the measuring assembly 500) is distributed through three-point support. Compared to single-pole support and double-leg brackets, it can effectively resist the impact of wind and water flow along the riverbank, such as the lateral force brought by the rotation of the line reel 400 and the extension of the telescopic component 300 during measurement, to prevent the device from tilting or swaying, and to ensure that the measuring component 500 is lowered vertically in the water. At the same time, the fixing base 120 can stably fix and support the telescopic component 300, preventing the telescopic component 300 from swaying during measurement. In addition, by adjusting the position of the pin 112 in different adjustment holes 111, the height of the tripod 110 can be easily adjusted to adapt to the measurement needs of different terrains.

[0038] refer to Figure 5The telescopic component 300 includes multiple connecting rods 310, all of which are conical in shape. The diameters of the multiple connecting rods 310 are different, and the multiple connecting rods 310 are nested together. The multiple connecting rods 310 adopt a nested design of "larger nesting smaller", which can be fully retracted when stored. The overall size is small and the weight is light, which reduces the load pressure on the tripod 110 and makes it easy to carry and move. At the same time, the conical shape combined with the "nested connection of different diameters" means that when the connecting rods 310 are stretched to the target length, the inner wall of the thicker connecting rod 310 will naturally fit with the outer wall of the thinner connecting rod 310, forming a self-locking effect of "the tighter the force, the tighter the fit".

[0039] The connecting rod 310 is provided with a guide ring 320 for guiding the measuring line 510, and the measuring line 510 is located inside the guide ring 320. The guide ring 320 can guide the measuring line 510. The guide ring 320 fixes the line in a preset path (such as a direction perpendicular to the water surface) by physical limiting, forcing the line to be lowered in a straight line, thereby reducing the measurement error caused by offset from the source. At the same time, by making the inner wall of the guide ring 320 usually smooth, such as a metal ring or a plastic ring, the hard contact between the line and the connecting rod 310 can be transformed into smooth sliding between the line and the inner wall of the ring, which greatly reduces wear and avoids blurring of marks or sudden breakage due to line wear, thus reducing the replacement frequency.

[0040] refer to Figure 5 The measuring component 500 includes a high-strength and wear-resistant measuring line 510 and multiple markers 520 mounted on the measuring line 510. The measuring line 510 is wound around a reel 400, and the markers 520 are evenly spaced on the measuring line 510. Each marker 520 has a unique color or marking. The high-strength measuring line 510 can withstand the weight of the measuring probe component 600 and is not easily broken due to pulling during the release or reeling process. Even if there are minor debris underwater, it can reduce the risk of "loss of the probe component due to line breakage" after being snagged, and improve the anti-interference capability of the device. At the same time, the evenly spaced markers 520 are equivalent to turning the measuring line 510 into a visual ruler so that the measuring personnel can clearly distinguish it when reading data.

[0041] refer to Figure 5The measuring probe assembly 600 includes a pressure sensor 610, a signal transmitter 620, and a counterweight 630 for the measuring probe assembly to touch the bottom. The counterweight 630 is mounted on the surface of the pressure sensor. The top of the pressure sensor 610 is connected to the signal transmitter 620, and the signal transmitter 620 is connected to the end of the measuring rope. The pressure sensor 610 and the signal transmitter 620 are electrically connected. The signal transmitter 620 converts the electrical signal of the pressure sensor 610 into identifiable data, which is then transmitted to the reading display assembly 200 on the shore. This allows the operator to obtain water depth data in real time without retrieving the measuring rope. At the same time, by setting the pressure sensor 610 and the counterweight 630, it is easier to make the pressure sensor 610 touch the bottom. The water depth can be inferred by the water pressure change of the pressure sensor 610. After the pressure sensor 610 touches the bottom, it will be located in the bottom silt. The thickness of the bottom silt can be observed by the pressure difference change of the pressure sensor 610 touching the bottom.

[0042] refer to Figure 6 The reading display component 200 includes a housing 210, a signal receiver 220, a microprocessor 230, and a display screen 240. The signal receiver 220, microprocessor 230, and display screen 240 are all mounted on the housing 210. The signal receiver 220 is wirelessly connected to the signal transmitter 620, the microprocessor 230 is electrically connected to the signal receiver 220, and the display screen 240 is electrically connected to the microprocessor 230. The signal receiver 220 is used to receive electrical signals sent by the measuring probe component 600 through wireless communication with the signal transmitter 620. The microprocessor 230 is electrically connected to the signal receiver 220 and can process and calculate the received electrical signals. Based on the conversion relationship between water pressure and water depth, the water depth data of the measuring point is obtained. The display screen 240 is electrically connected to the microprocessor 230 and is used to intuitively display the water depth data for easy reading by the measuring personnel.

[0043] The implementation principle of this application embodiment is as follows: In implementation, the tripod 110 is adjusted and fixed by inserting the pin 112 into the adjustment hole 111 on the tripod 110. Then, the connecting rod 310 on the telescopic assembly 300 is fixed to the fixed seat 120 on the tripod 110. The line-feeding reel 400 and the measuring assembly 500 are then installed on the telescopic assembly 300. The telescopic assembly 300 is then extended or retracted, allowing the measuring probe assembly 600 to reach the desired measurement position. The line-feeding reel 400 is then rotated to move the measuring probe assembly 600 downwards into the water area to be measured. Then observe the measuring line 510 on the measuring component 500, observe the marker 520 on the measuring line 510, and measure the number of water bodies entering the water through the marker 520 to measure the water depth. It works with the pressure sensor 610 on the measuring probe component 600 to transmit the water pressure to the signal transmitter 620. The signal generator transmits the signal to the signal receiver 220 of the reading display component 200. The signal receiver 220 transmits the signal to the microprocessor 230 for processing. The processed value is displayed on the display screen 240 so that the user can observe and record it. This makes it easy for the user to operate, and the operation is simple and the cost is low.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
