AI Technical Summary
In existing technologies, when measuring water depth using a manual measuring rope, it is difficult to accurately determine when the counterweight sinks to the bottom, which may cause the measuring rope to slack, resulting in an overestimation of the measurement result and low accuracy.
The shipborne water depth measuring device utilizes pressure sensors and elastic components in conjunction with a grooved wheel and support. When the sensor touches the bottom, it triggers a signal to control the winding of the rope. Combined with a submersible frame and water-proof components, this ensures that the measuring rope does not slack, thereby improving measurement accuracy.
This technology enables timely retrieval of the pressure sensor during the measurement process, eliminating errors caused by slack in the measuring rope and improving the accuracy of water depth measurement. Furthermore, the submersible support prevents contact between the sensor and sediment, further enhancing the accuracy of the test results.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of water depth detection technology, specifically relating to a shipborne water depth measurement device. Background Technology
[0002] Pond and reservoir water depth measurement is a fundamental task in water resource management. Its main purpose is to accurately determine the water storage capacity of a body of water, providing a scientific basis for flood control, drought relief, agricultural irrigation planning, and ecological protection. For outdoor water depth measurement, common methods include using a remotely operated boat carrying sonar equipment to measure water depth based on sound waves. However, sonar equipment is relatively expensive, with high manufacturing costs. To save costs, another method involves manually submerging a measuring rope with a weight attached into the water and measuring the length of the rope underwater to determine the water depth.
[0003] In related prior art, such as Chinese Patent No. CN220729257U, a channel depth measuring device is disclosed. This device includes a mounting base with a C-shaped plate on one side of its top. A drive motor is fixedly mounted on one side of the C-shaped plate. A rotating shaft is movably mounted at the output end of the drive motor. A winding rod is movably mounted at one end of the rotating shaft, and a measuring rope is movably mounted at the outer end of the winding rod. A counterweight is fixedly mounted at the bottom of the measuring rope. This device uses the method of lowering the counterweight to the bottom of the water and measuring the length of the measuring rope submerged in the water to determine the water depth.
[0004] When using the above method, it is difficult to judge when the counterweight sinks to the bottom, and the measuring rope is prone to being in a slack state, resulting in an overestimation of the measurement result and low measurement accuracy. Utility Model Content
[0005] The present invention aims to provide a shipborne water depth measurement device to solve the problem of low measurement accuracy in the above-mentioned solutions.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A shipborne water depth measurement device includes a hull, a support, and a measurement assembly. The hull has a through-hole on its inner bottom wall, and a cylindrical body is fixedly installed around the through-hole. An installation plate is fixedly installed above the cylindrical body inside the hull. The support is movably mounted on the top of the installation plate via an elastic member. A grooved wheel is rotatably mounted on the top of the support. An L-shaped support plate is fixedly mounted on the top of the installation plate. A first sensor capable of contacting the support is fixedly mounted at the bottom of the horizontal section of the support plate. The measurement assembly includes a pressure sensor, a rope, and a roller. The roller is rotatably mounted inside the hull. One end of the rope is wound around the roller and connected to it, while the other end is wound around the grooved wheel and linked to the pressure sensor. The hull also houses a main control board, a communication module, and a drive assembly for rotating the roller. The main control board is connected to the first sensor, the drive assembly, and the communication module.
[0008] The principle and effects of this technical solution:
[0009] During measurement, the boat is remotely controlled to the measurement location. Then, a signal is sent to the main control board via the communication module, which controls the drive assembly to rotate the roller to extend the rope. The pressure sensor moves downward, and the rope transfers the weight of the pressure sensor to the grooved wheel, causing the grooved wheel and the support to move downward. At this time, the elastic component deforms and becomes elastic. When the pressure sensor touches the bottom, the weight transmitted by the rope decreases, and the elastic component pulls the support back to its original position. When the support returns to its original position, it touches the first sensor, which sends an electrical signal to the main control board. The main control board then controls the drive assembly to rotate the roller to wind up the rope. After the remotely controlled boat returns, the data from the pressure sensor is read. The water depth corresponding to the maximum pressure is the water depth at that monitoring point.
[0010] By using the above settings, the elastic component pushes the bracket to reset when the pressure sensor touches the bottom, which can prompt the testing personnel to retrieve the pressure sensor in time after it touches the bottom. It can also eliminate the measurement error caused by the measuring rope being in a slack state, thus solving the problem of low measurement accuracy in the above scheme.
[0011] This invention also includes a submersible frame, which is a hollow frustum-shaped structure. The pressure sensor is fixedly connected to the inner top wall of the submersible frame, and through grooves are provided at intervals on the side walls of the submersible frame. The other end of the rope is connected to the pressure sensor or the submersible frame. Through the above arrangement, the submersible frame provides support for the pressure sensor, preventing the pressure sensor from contacting the sediment at the bottom of the water, thus further improving the accuracy of the detection results. The actual water depth is then the water depth measured by the pressure sensor plus the distance between the pressure sensor and the bottom of the submersible frame.
[0012] In this invention, a counterweight plate is fixedly connected to the bottom of the submersible frame. This design increases the deformation of the elastic component, thereby preventing accidental activation.
[0013] In this utility model, a water-blocking assembly is provided inside the cylinder. An inner edge is fixedly provided on the top of the inner side wall of the cylinder. Guide rods are fixedly provided at intervals on the top of the inner edge. The water-blocking assembly includes a movable plate and two sets of symmetrically arranged water-blocking units. The movable plate is slidably sleeved on the two guide rods. The water-blocking unit includes a baffle plate and a connecting rod. One end of the baffle plate is rotatably connected to the bottom of the inner edge. The two ends of the connecting rod are rotatably connected to the top of the baffle plate and the bottom of the movable plate, respectively. The movable plate has a through-hole between the two connecting rods. The rope is threaded through the hole, and the diameter of the top of the submersible frame is larger than the inner diameter of the hole.
[0014] In this utility model, the bottom of the bracket has spaced vertical rods that slide through the mounting plate. The elastic member is a tension spring that wraps around the vertical rods, with the two ends of the tension spring connected to the bottom of the vertical rods and the bottom of the mounting plate, respectively.
[0015] In this invention, a second sensor is fixedly installed at the bottom of the mounting plate, and the top of the movable plate can contact the second sensor. The second sensor is connected to the main control board.
[0016] The principle and effects of this technical solution:
[0017] During the ship's movement, the pressure sensor and submersible are at a high position. At this time, the submersible pushes a movable plate to the high position. The movable plate, via a connecting rod, pulls a shield against the bottom of the inner edge. The two shields then contact each other, covering the opening formed by the inner edge. When the drive assembly rotates the roller to extend the rope, the submersible and pressure sensor fall freely. The rope exerts a downward tension on the grooved wheel, causing the grooved wheel and support to move downwards. During this process, the tension spring deforms under tension. When the submersible touches the bottom, the downward force exerted by the rope on the grooved wheel decreases, and the tension spring... Pulling the support upwards triggers the first sensor, which sends a signal to the main control board, causing it to control the drive assembly to wind up the rope. When the top of the submersible frame contacts the movable plate, it pushes the movable plate upwards. When the movable plate reaches the high position, the two shields are pulled back to a horizontal position. At this time, the movable plate is also in contact with the second sensor, which sends a signal to the main control board, causing it to control the drive assembly to stop rotating the roller. At the same time, the main control board also sends a signal to the inspection personnel on the shore via the communication module to control the ship to return to port.
[0018] With the above setup, the sliding plate can be moved up by the submersible frame to pull the cover plate to cover the holes in the inner edge of the hull, thereby preventing water from rushing into the hull when the ship is moving. By using the second sensor, the rotating roller can be stopped in time and the inspection personnel can be notified to maneuver the ship back to shore.
[0019] In this invention, a limiting block is fixedly provided on the top of the mounting plate, and a transversely penetrating limiting hole is provided on the limiting block. The rope slides through the limiting hole. Through the above arrangement, the rope can be limited, so that the rope and the grooved wheel are coplanar.
[0020] In this invention, the drive assembly includes a motor and a chain drive assembly. The roller is connected to the output end of the motor via the chain drive assembly. The motor is fixedly installed inside the hull and connected to the main control board. This configuration achieves the purpose of enabling the drive assembly to rotate the roller.

[0028] Example:
[0029] As attached Figure 1-5As shown, this utility model discloses a shipborne water depth measuring device, including a hull 10, a support 20, and a measuring assembly.

The main control board 61 is connected to the first sensor 41, the drive assembly and the communication module 62 respectively. The hull 10 can be modified based on a baiting boat with a bottom compartment. The modification method is to seal the bottom compartment of the baiting boat and then install the cylinder 12 and mounting plate 13 and other structures. The error range of the pressure sensor 51 is ±0.5kPa. The top of the hull 10 has a cover plate for shielding the interior of the hull 10 (not shown in the diagram of the internal structure of the hull 10).
[0030] In this embodiment, a submersible frame 80 is also included. The submersible frame 80 is a hollow frustum structure. The pressure sensor 51 is fixedly connected to the inner top wall of the submersible frame 80. The side walls of the submersible frame 80 are provided with through grooves 81 at intervals. The other end of the rope 52 is connected to the pressure sensor 51 or the submersible frame 80.
[0031] In this embodiment, a counterweight plate 82 is fixedly connected to the bottom of the sinking frame 80.
[0032] In this embodiment, a water-blocking assembly is provided inside the cylinder 12. An inner edge 15 is fixedly provided on the top of the inner sidewall of the cylinder 12. Guide rods 16 are fixedly provided at intervals on the top of the inner edge 15. The water-blocking assembly includes a movable plate 91 and two sets of symmetrically arranged water-blocking units. The movable plate 91 is slidably sleeved on the two guide rods 16. The water-blocking unit includes a baffle plate 92 and a connecting rod 93. One end of the baffle plate 92 is rotatably connected to the bottom of the inner edge 15. The two ends of the connecting rod 93 are rotatably connected to the top of the baffle plate 92 and the bottom of the movable plate 91, respectively. The weight of the baffle plate 92 is set to be able to pull the movable plate 91 downward through the connecting rod 93. The movable plate 91 has a through hole 911 between the two connecting rods 93. The rope 52 is passed through the hole 911, and the diameter of the top of the sinking frame 80 is larger than the inner diameter of the hole 911.
[0033] In this embodiment, the bottom of the bracket 20 has spaced vertical rods 22, which slide through the mounting plate 13. The elastic member 30 is a tension spring wrapped around the vertical rod 22, and the two ends of the tension spring are respectively connected to the bottom of the vertical rod 22 and the bottom of the mounting plate 13.
[0034] In this embodiment, a second sensor 42 is fixedly installed at the bottom of the mounting plate 13, and the top of the movable plate 91 can contact the second sensor 42. The second sensor 42 is connected to the main control board 61.
[0035] In this embodiment, a limiting block 17 is fixedly provided on the top of the mounting plate 13, and a limiting hole is provided on the limiting block 17, through which the rope 52 slides.
[0036] In this embodiment, the drive assembly includes a motor 71 and a chain drive assembly 72. The roller 53 is connected to the output end of the motor 71 via the chain drive assembly 72. The motor 71 is fixedly installed inside the hull 10 and connected to the main control board 61.
[0037] The specific implementation process is as follows:
[0038] During measurement, the hull 10 is driven to the measurement position via a remote control device. Then, a signal is sent to the main control board 61 via the communication module 62, which controls the drive assembly to rotate the roller 53 to extend the rope 52. The pressure sensor 51 moves downward accordingly. The rope 52 transmits the weight of the pressure sensor 51 to the grooved wheel 21, causing the grooved wheel 21 and the bracket 20 to move downward. At this time, the elastic member 30 deforms and has elasticity. When the pressure sensor 51 touches the bottom, the weight transmitted by the rope 52 decreases. The elasticity of the elastic member 30 counteracts the downward weight transmitted by the rope 52 and pulls the bracket 20 upward to reset. When the bracket 20 resets, it touches the first sensor 41. The first sensor 41 sends an electrical signal to the main control board 61. The main control board 61 controls the drive assembly to rotate the roller 53 to wind up the rope 52. After the remote-controlled hull 10 returns, the data of the pressure sensor 51 is read. The water depth corresponding to the maximum pressure is the water depth of the monitoring point.
[0039] During the movement of the hull 10, the pressure sensor 51 and the submersible 80 are in a high position. At this time, the submersible 80 pushes the movable plate 91 to move to the high position. The movable plate 91 pulls the cover plate 92 to abut against the bottom of the inner edge 15 through the connecting rod 93. At this time, the two cover plates 92 contact each other and cover the hole formed by the inner edge 15. When the drive assembly drives the roller 53 to rotate to extend the rope 52, the submersible 80 and the pressure sensor 51 fall freely. The rope 52 applies a downward pulling force to the grooved wheel 21, causing the grooved wheel 21 and the support 20 to move downward. During this process, the tension spring is stretched and deformed. When the submersible 80 touches the bottom, the downward force applied by the rope 52 to the grooved wheel 21 decreases, and the tension spring... The spring pulls the bracket 20 upward to trigger the first sensor 41. The first sensor 41 sends a signal to the main control board 61, which controls the drive assembly to drive the roller 53 to rotate and wind up the rope 52. When the top of the submersible frame 80 contacts the movable plate 91, it pushes the movable plate 91 upward. When the movable plate 91 moves to the high position, the two shields 92 are pulled back to the horizontal position. At this time, the movable plate 91 is also in contact with the second sensor 42. The second sensor 42 sends a signal to the main control board 61, which controls the drive assembly to stop rotating the roller 53. At the same time, the main control board 61 also sends a signal to the inspection personnel on the shore to control the ship 10 to return to port via the communication module.
