Description

Technical Field

[0001] This utility model belongs to the field of water depth measurement technology, specifically relating to a water depth measurement device for surveying water areas. Background Technology

[0002] In order to clearly understand the detailed situation of ponds, small lakes and other bodies of water, it is necessary to conduct water surveys. Since the water depth directly affects the personal safety of pedestrians, it is necessary to use water depth detection devices to detect the water depth.

[0003] Current methods for water depth surveying typically employ sonar, depth sounding rods, or cantilever line surveying. However, sonar is too expensive and requires stringent installation conditions. Depth sounding rods require access to the center of ponds or lakes via boats, which, in areas without boats, necessitate transporting the vessel to the target area—a labor-intensive and costly process. Consequently, measurements are limited to shallow waters near the shore, resulting in a small measurement area, poor accuracy, and an inability to accurately reflect the water depth distribution. Cantilever line surveying, for wider areas, requires large cantilever setups and line-laying systems, leading to high transportation costs. Utility Model Content

[0004] The present invention aims to provide a water depth measurement device for surveying water areas, which facilitates the transportation, carrying, and use of the measurement equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for measuring water depth in a surveying area, comprising...

[0006] The hull has a drive mechanism installed at the bottom, a line-laying port is opened in the hull, and a baffle plate is fixed inside the hull, which is arranged around the circumference of the line-laying port.

[0007] The wire feeding mechanism includes a mounting frame, a take-up roller, and a motor. The mounting frame is installed inside the hull, the take-up roller is rotatably installed inside the mounting frame, the motor is installed on the outer wall of the mounting frame, and the movable end of the motor is connected to the take-up roller for transmission. A measuring rope is provided on the take-up roller, and the end of the measuring rope passes through the wire feeding port and is fixed with a measuring cone.

[0008] The cable tie is installed on the enclosure panel. A movable frame is slidably fitted inside the cable tie. A grooved wheel is installed inside the movable frame. The measuring rope is also attached to the grooved wheel. A pressure sensor and an elastic telescopic rod are installed inside the cable tie. The top of the elastic telescopic rod is connected to the bottom of the movable frame.

[0009] The monitoring system is installed on the fence.

[0010] The control box, installed inside the ship's hull, contains a mobile power supply, a control module, and a wireless sensor module.

[0011] The principle and effects of this technical solution:

[0012] 1. The wire-laying mechanism and other equipment are moved into the water via the hull, and the wireless sensors on the control box transmit and receive signals, allowing surveyors to remotely control the measuring device from the shore via remote control or other control devices. The hull is only equipped with the necessary wire-laying mechanism, monitoring mechanism, wire-binding frame, and movable frame, making the hull size and structure relatively small. Compared with the cantilever wire-laying detection method, this solution is easier to carry and transport, can operate at a greater distance from the shore in the water, and is cheaper than sonar detection.

[0013] 2. The cable-laying mechanism is moved to the measurement location in the water by the hull. When the motor is not winding the take-up roller, the measuring rope will spontaneously detach from the take-up roller and enter the water under the gravity of the measuring cone. The measuring rope then rests on the movable frame, and its weight causes the movable frame to contact the pressure sensor. When the measuring cone touches the bottom, it no longer provides downward force to the measuring rope, causing a sudden drop in pressure on the grooved reel. At this point, the elastic telescopic rod tends to pull the movable frame away from the pressure sensor. The monitoring mechanism can then monitor the scale of the measuring rope to obtain accurate water depth data. The grooved reel provides a certain guiding and limiting effect on the release and retraction of the measuring rope.

[0014] 3. By incorporating a mobile power supply, control module, wireless sensors, pressure sensors, monitoring mechanism, and drive mechanism, the power consumption of all electronic components can be provided by the mobile power supply. The control module can receive signals from the pressure sensor and monitoring mechanism and transmit them to the mobile terminal for measurement personnel reference. The enclosure also increases the device's draft, mitigating the increased overall weight of the measuring cone and rope after water ingress.

[0015] The present invention is further configured to include a wire harnessing mechanism, which includes a wire harness ring and a support rod. The support rod is fixed on both sides of the wire harness ring, and the end of the support rod is slidably engaged with the baffle plate. The wire harness ring is slidably sleeved on the measuring rope, and the wire harness ring is located between the measuring cone and the wire harness frame.

[0016] The principle and effect of this technical solution: By setting up the cable tie, impurities adhering to the rope can be scraped off during the winding and unwinding of the measuring rope. Furthermore, the sliding fit allows the cable tie to move back and forth, thus adapting to possible swaying, shaking, and displacement during the winding and unwinding of the rope.

[0017] The present invention is further configured such that: a vertical pole is fixed to the bottom of the cable tie frame, and the vertical pole is fixed to a support rod.

[0018] The principle and effect of this technical solution: Since the take-up roller may have a certain axial length (if the water is too deep, the required length of the measuring rope is longer, and a shorter take-up roller has a larger diameter after winding, which is not conducive to carrying and storage), the measuring rope is wound obliquely on the take-up roller. Therefore, when the wire is unwound, if the position of the grooved wheel remains unchanged, there may be an inclination between the measuring rope and the grooved wheel. In severe cases, the measuring rope may detach from the grooved wheel. However, after the wire harness is installed on the support rod, when the measuring rope on the take-up roller is tilted to the grooved wheel, the pressure of the tilt can drive the grooved wheel to drive the support rod to slide horizontally, thereby controlling and adjusting the position of the grooved wheel and the wire harness ring.

[0019] The present invention is further configured such that: a slider is fixed to the end of the support rod, and the slider is slidably installed inside the enclosure plate.

[0020] The principle and effect of this technical solution: The slider design allows the support rod to slide stably relative to the enclosure panel.

[0021] The present invention is further configured such that ball bearings are installed at the top and bottom of the slider respectively.

[0022] The principle and effect of this technical solution: The ball bearings reduce the friction between the slider, support rod and the enclosure plate, making it easier for the wire harness ring and support rod to slide relative to the enclosure plate for position adjustment.

[0023] The present invention is further configured such that: the measuring cone includes a solid part and a hollow part, the hollow part is located above the solid part, and a water inlet hole is provided at the top of the solid part.

[0024] The principle and effect of this technical solution: The design of the hollow and solid parts makes the device lighter when not in use. When in use, the hollow part is submerged in water, and water can enter the hollow part through the inlet hole. This results in a greater pulling force required when lifting the measuring cone, which means a greater pressure of the measuring rope on the grooved wheel. Consequently, the pressure sensor can detect the sudden change in pressure when the measuring cone touches the bottom and when it is lifted, so as to obtain an accurate image of the timing of the monitoring mechanism based on the pressure situation.

[0025] The present invention is further configured such that: the elastic telescopic rod includes a rod body, a limiting plate and a cylinder body, the cylinder body is fixed to the cable tie frame, the limiting plate is slidably fitted inside the cylinder body, the bottom of the rod body is fixed to the limiting plate, the top of the rod body is fixed to the movable frame, and a spring is provided at the bottom of the limiting plate.

[0026] The principle and effect of this technical solution: The limiting plate limits the rod so that it cannot detach from the cylinder. The spring rebound force drives the rod to move upward after the measuring cone touches the bottom. This causes the movable frame to move away from or reduce the pressure on the pressure sensor. When the measuring cone descends or is lifted up, the pressure of the measuring cone on the measuring rope acts on the grooved wheel, causing the grooved wheel to drive the movable frame to press against the pressure sensor.

This device can be modified from commercially available remote-controlled boats and unmanned boats, and is an existing commercially available product, so it is only briefly described here). The drive mechanism 102 and the hull 101 together constitute a remote-controlled boat or unmanned boat. A line-laying port 103 is opened at the bottom of the inner side of the hull 101. A baffle plate 104 is fixed inside the hull 101. The baffle plate 104 is arranged around the circumference of the line-laying port 103, and the baffle plate 104 is used to prevent water from entering the hull 101 from the line-laying port 103 after the hull 101 has a draft.

[0043] The wire feeding mechanism includes a mounting frame 201, a take-up roller 202, and a motor 203.

The hollow part 207 is located above the solid part 206, and a water inlet hole is opened at the top of the solid part 206.

[0044] The wire-binding mechanism includes a wire-binding ring 501 and support rods 502. Support rods 502 are fixed to both sides of the wire-binding ring 501. The ends of the support rods 502 are slidably engaged with the enclosure plate 104. A slider 503 is fixed to the end of the support rod 502 and is slidably installed inside the enclosure plate 104.

The bottom of the movable frame 302 can abut against the pressure sensor 304.

[0046] The monitoring unit 401 is installed on the fence panel 104. The monitoring unit 401 can be an existing commercially available visual monitoring component such as a monitoring device.

[0047] The control box 501 is installed inside the hull 101 and is located on the side of the cofferdam 104 away from the mounting frame 201 (i.e., the mounting frame 201 and the control box 501 are located on opposite sides of the cofferdam 104 to balance the center of gravity). The control box 501 contains a power supply, a control module, and a wireless sensor module. The power supply is electrically connected to the control module, and the control module is electrically connected to the wireless sensor module, the drive mechanism 102, and the monitoring mechanism 401. The control module is an electronic component with a PLC circuit board, which can receive and send electronic signals. The wireless sensor module is used to wirelessly transmit or receive signals to transmit data to the mobile terminal or the shore, and to receive control commands from the mobile terminal or the shore. All of the above components are commercially available products, and users can simply combine and integrate them according to their needs.

[0050] In use, the mobile terminal controls the drive mechanism 102 to move the hull 101 to the designated area, then adjusts the direction of the hull 101 to make the drive mechanism 102 run at low speed to overcome the water flow (the drive mechanism 102 is turned off in still water). Then the motor 203 releases the restriction on the take-up roller 202, and the line is released. The pressure sensor 304 monitors the pressure change at all times, and the monitoring mechanism 401 monitors and records the scale of the measuring rope 204 on the wire harness ring 501.
