Abstract
Description
Technical Field
[0001] This utility model relates to a position adjustment device for river hydrological monitoring equipment. Background Technology
[0002] Accurate monitoring of river hydrological data is crucial before constructing hydropower stations, conducting hydrological research, or implementing water conservancy projects in a river channel. This data, including water level, flow velocity, and discharge, is essential for assessing the river's hydrological characteristics, designing water conservancy projects, and predicting natural disasters such as floods. However, existing hydrological monitoring devices have several limitations. For example, bed-insertion monitoring devices (such as patent "CN220251977U, A River Measurement Mechanism") can typically only be installed in shallow water areas, making it difficult to effectively monitor high-velocity, high-discharge areas in the middle of the river. Furthermore, the installation and maintenance of such devices require divers, posing certain safety risks. While cantilevered monitoring devices on the bank (such as patent "CN219121397U, A Device for Measuring Water Level and Flow Velocity") avoid direct contact with the river water, their monitoring range is limited, failing to cover the entire river channel, especially the central region. In practical applications, these devices often only provide localized hydrological data, failing to meet the need for comprehensive and accurate monitoring of river hydrological conditions. Furthermore, the existing monitoring devices are installed in fixed locations, making it impossible to flexibly adjust the monitoring point positions according to actual monitoring needs. In some complex river environments, such as bends and bottlenecks, these fixed monitoring devices are difficult to adapt to changing hydrological conditions, resulting in insufficient representativeness and accuracy of the monitoring data. Utility Model Content
[0003] This invention addresses the problems of limited monitoring range, fixed location, poor adaptability, insufficient intelligence, and poor stability of existing hydrological monitoring devices. It proposes a river hydrological monitoring equipment location adjustment device that can flexibly adjust the monitoring position and depth, adapt to various river environments, and has intelligent control and data transmission functions, so as to improve the comprehensiveness, accuracy, and efficiency of monitoring.
[0004] To solve the above problems, the technical solution of this utility model is as follows:
[0005] A device for adjusting the position of a river hydrological monitoring device includes a support frame, with both ends of the support frame fixedly connected to the hull of a vessel. A first winch is mounted on the support frame, and a steel wire rope on the first winch is connected to a lead weight. A hydrological monitoring device is mounted on the lead weight. The device also includes two second winches, each fixedly mounted on one bank of the river. The steel wire ropes of the two second winches are connected to both ends of the support frame. A battery, a first Internet of Things (IoT) controller, and a first wireless communication module are located inside the vessel. The hydrological monitoring device and the first winch are connected to the input terminal of the first IoT controller. The first IoT controller communicates with a terminal via the first wireless communication module.
[0006] A diagonal rod is fixedly connected to the support between the two hulls, and a grooved wheel is fitted at the top of the diagonal rod. The wire rope of the first winch is wound around the grooved wheel.
[0007] A first rotary encoder that is linked to the grooved wheel is installed at the top of the slanted rod. The first rotary encoder is connected to the input terminal of the first Internet of Things controller.
[0008] The ship is equipped with solar charging panels, which are connected to batteries via charging modules.
[0009] The beneficial effects of this utility model are as follows:
[0010] 1. Wide-range position adjustment capability: By controlling the second winch on both banks of the river to raise and lower the steel cable, the hydrological monitoring equipment installed on the hull can be adjusted over a wide range. Whether upstream or downstream, or on the left or right bank of the river, the monitoring equipment can be moved flexibly to ensure it reaches the optimal monitoring position, thereby achieving comprehensive monitoring of the entire river and solving the problem of limited monitoring range of existing devices.
[0011] 2. Depth Adjustment Function: By controlling the winding and unwinding of the steel wire rope by the first winch, the submersion depth of the hydrological monitoring equipment can be precisely adjusted. This function allows the monitoring equipment to flexibly adjust the monitoring depth according to different hydrological conditions and monitoring needs, thereby acquiring hydrological data from different water layers and improving the comprehensiveness and accuracy of the monitoring data.
[0012] 3. High adaptability: The device of this invention has a simple structure, is easy to install and maintain, and can adapt to different river environments and hydrological conditions. Whether it is a shallow or deep river, a fast-flowing or slow-flowing river, effective hydrological monitoring can be achieved by adjusting the parameters and position of the device. In addition, the modular design of the device allows it to be expanded and upgraded according to actual needs, exhibiting strong adaptability and scalability.
[0013] In summary, the position adjustment device for river hydrological monitoring equipment of this utility model can effectively solve many shortcomings of existing hydrological monitoring devices, and provides an efficient, flexible and reliable solution for river hydrological monitoring, which has broad application prospects and important practical significance.

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figure 1 and 2As shown, a river hydrological monitoring equipment position adjustment device includes a support 5, with both ends of the support 5 fixedly connected to the hull 1. A first winch 3 is installed on the support 5, and a steel wire rope on the first winch 3 is connected to a lead weight 7. A hydrological monitoring equipment 6 is installed on the lead weight 7. The device also includes two second winches 8, which are fixedly installed on both banks of the river. A lifting ring is connected to both ends of the support 5. One end of the steel wire rope of the two second winches 8 is connected to the lifting ring 18 at both ends of the support 5. A battery, a first Internet of Things (IoT) controller, and a first wireless communication module are provided inside the hull 1. The hydrological monitoring equipment 6 and the first winch 3 are connected to the input terminal of the first IoT controller. The first IoT controller communicates with the terminal through the first wireless communication module. The first IoT controller and the second IoT controller described below are "SIC-5010-IPSIP IoT Controller (Sinrui Technology)", the first wireless communication module and the second wireless communication module described below are "TL112 4G CAT.1 Controller (Jixun IoT)", the terminal is a computer, the hydrological monitoring equipment 6 is such as a current meter, the current meter transmits the monitoring data signal to the first IoT controller, the first IoT controller transmits the monitored data to the computer through the first wireless communication module, and the staff on the shore control the first winch 3 to wind up and unwind the steel wire rope through the first IoT controller.
[0024] Wide-range position adjustment capability: By controlling the winding and unwinding of steel cables by the second winches 8 on both banks of the river, the hydrological monitoring equipment 6 installed on the hull 1 can be adjusted over a wide range. For example, when the hydrological monitoring equipment 6 needs to be adjusted downstream, the steel cables on both second winches 8 are simultaneously unwound; when the hydrological monitoring equipment 6 needs to be moved to the left bank, the steel cable on the right bank second winch 8 is unwound, and the steel cable on the left bank second winch 8 is wound up. This flexible position adjustment capability solves the problem of the limited monitoring range of existing devices, enabling comprehensive monitoring of the entire river channel.
[0025] Depth Adjustment Function: By controlling the winding and unwinding of the steel wire rope by the first winch 3, the submersion depth of the hydrological monitoring equipment 6 can be precisely adjusted. For example, when monitoring data from deeper water layers is required, the first winch 3 can be used to wind and unwind the steel wire rope, causing the lead weight 7 to lower the hydrological monitoring equipment 6 to the designated depth. This function allows the monitoring equipment to flexibly adjust its monitoring depth according to different hydrological conditions and monitoring needs, thereby acquiring hydrological data from different water layers and improving the comprehensiveness and accuracy of the monitoring data.
[0026] A diagonal brace 9 is fixedly connected to a support 5 between the two hulls 1. A grooved sheave 2 is fitted to the top of the diagonal brace 9, and the wire rope of the first winch 3 is wound around the grooved sheave 2. The use of a double hull 1 serves two purposes: firstly, it ensures balance and prevents capsizing; secondly, it allows for… Figure 1As shown, when the first winch 3 lifts the hydrological monitoring equipment 6 onto the inclined bar 9, the hydrological monitoring equipment 6 is positioned just above the middle of the two hulls 1. This prevents the monitoring equipment 6 from hitting the rocks on the riverbank or the riverbed during the process of moving the equipment from the bank to the middle of the river, thus protecting the hydrological monitoring equipment 6.
[0027] A first rotary encoder 10, linked to the grooved wheel 2, is installed at the top of the inclined rod 9. The first rotary encoder 10 is connected to the input terminal of the first IoT controller. The first rotary encoder 10 is an Omron E6B2-CWZ6C. The first rotary encoder 10 can accurately measure the length of the wire rope of the first winch 3, thereby achieving precise control over the water depth of the hydrological monitoring equipment 6. By receiving the signal from the first rotary encoder 10 through the first IoT controller, the staff can monitor and adjust the depth of the monitoring equipment in real time on the terminal device, ensuring that the monitoring equipment can reach the optimal monitoring position, further improving the accuracy and reliability of the monitoring data.
[0028] A solar charging panel 4 is installed on the hull 1, and the solar charging panel 4 is connected to a battery via a charging module. The solar charging panel has a power of 200W, and the battery capacity is 100Ah, which can meet the equipment's continuous operation for more than 48 hours. The solar charging panel 4 can convert solar energy into electrical energy and charge the battery through the charging module. In river environments without power supply, the combination of the solar charging panel 4 and the battery provides a stable power supply for the device, extends the device's endurance, ensures stable operation of the device in long-term hydrological monitoring tasks, and improves the device's practicality and reliability.
[0029] like Figure 3 As shown, a second rotary encoder 11 is installed on the frame of the second winch 8. The second rotary encoder 11 is connected to the drum drive of the second winch 8. An electrical box 13 is located on one side of the second winch 8. The electrical box 13 contains a second IoT controller and a second wireless communication module. The second rotary encoder 11 is connected to the input terminal of the second IoT controller, and the second winch 8 is connected to the output terminal of the second IoT controller. The second IoT controller communicates with the terminal through the second wireless communication module. Both the first IoT controller and the second IoT controller are connected to the terminal, which then networks and controls them. The second encoder 11 is a Pepperl+Fuchs RVI58N-011K1R61N-1024 with an accuracy of 0.01m.
[0030] The second rotary encoder 11 monitors the number of rotations of the drum of the second winch 8, and transmits the monitoring results to the terminal computer via the second wireless communication module. This calculates the length of the wire rope wound and unwound by the second winch 8, and the second IoT controller controls the start and stop of the second winch 8. The terminal adjusts the position of the hull 1 by controlling the amount of wire rope wound and unwound by the two second winches 8, for example: Figure 1 In the middle, when the steel wire rope of the second winch 8 on the left is released and the steel wire rope of the second winch 8 on the right is wound up, the hull moves to the right; when the steel wire ropes of both second winches 8 are released at the same time, the hull moves downward under the push of the water flow. In this way, the position of the hull can be monitored and adjusted by controlling the steel wire ropes of the two second winches 8 separately.
[0031] like Figure 4 As shown, the second winch 8 is installed on a concrete foundation with dimensions of 2m × 2m × 1m. The second winch 8 and the electrical box 13 are fixed with pre-embedded bolts. A rain shelter 16 is provided on the concrete foundation, and the second winch 8 and the electrical box 13 are located under the rain shelter 16. The concrete foundation provides a stable installation platform for the second winch 8, ensuring its operational stability in complex environments. The rain shelter 16 effectively prevents rainwater and dust from corroding the second winch 8 and the electrical box 13, extending the service life of the equipment and improving the reliability and durability of the device.
[0032] like Figure 5 As shown, a support 17 is provided on the concrete foundation. A pair of vertical rollers 14 and a pair of horizontal rollers 15 are mounted on the support 17. These rollers form a square hole structure, through which the wire rope of the second winch 8 passes. The rollers have a diameter of 200mm, are made of stainless steel, and are mounted on the support via bearings. The vertical rollers 14 and horizontal rollers 15 provide guidance for the wire rope of the second winch 8, ensuring smooth operation during winding and unwinding, and preventing tangling or jamming. This guiding structure not only improves the operating efficiency of the device but also reduces wire rope wear, extends its service life, and further enhances the reliability and stability of the device.

The scope of protection of this utility model should not be considered as limited to the specific forms described in the embodiments. The scope of protection of this utility model also extends to equivalent technical means that can be conceived by those skilled in the art based on the inventive concept.
