Description

Technical Field

[0001] The invention relates to the technical field of river channel detection equipment, and in particular to a river channel cross-sectional dimension detection device. Background Art

[0002] In many important fields related to rivers, such as water conservancy project construction, water resources management, and flood prevention and disaster reduction, the accurate measurement of river cross-sectional dimensions plays a vital role. Accurately obtaining river cross-sectional dimension information can provide a key basis for the planning and design of water conservancy projects, the rational allocation of water resources, and the assessment and prevention of flood risks.

[0003] At present, there are many methods and equipment for measuring the cross-sectional dimensions of river channels. However, these existing measurement methods generally have some problems that need to be solved urgently.

[0004] The traditional manual measurement method mainly relies on manual use of measurement tools to collect data on the river site. This method not only requires a lot of manpower and time costs, resulting in extremely low measurement efficiency, but also the accuracy of the measurement results is easily affected by human factors such as the measurement personnel's operating skills, experience, and working conditions, making it difficult to ensure the stability and reliability of the measurement accuracy.

[0005] Although some existing automated detection equipment has improved measurement efficiency and reduced manual intervention to a certain extent, it has the defects of complex structure and high cost. These devices are usually composed of multiple complex mechanical components and electronic systems, and the manufacturing and maintenance costs are very high, which greatly limits their wide application in actual engineering. In addition, these devices often lack sufficient adaptability when facing different terrains and different river environments. For example, in some areas where the river channels are different, the river channel width varies greatly and the frequency of changes is high, the equipment may not be able to quickly adapt to various environments, resulting in a greater impact on the measurement speed.

[0006] In summary, the existing river section dimension measurement methods and equipment have many deficiencies in terms of efficiency, accuracy, cost and adaptability, and cannot well meet the diversified and highly adaptable measurement needs in actual engineering. Therefore, it is of great practical significance and application value to develop a river section dimension detection device with simple structure, convenient operation, high adaptability, reasonable cost and adaptability to different river environments.

A clamping box 10 is fixedly installed on one end of the transmission device 5. A telescopic wire plate 1001 is fixedly installed on the upper inner wall of the clamping box 10. The telescopic wire plate 1001 is a telescopic cable reel, which can achieve the purpose of scaling the cable according to the movement of the moving plate 801, so as to facilitate the power supply to the moving plate 801 and the transmission of measurement data. A telescopic clamping shaft 1002 is symmetrically installed on the inner wall of the clamping box 10, which is used to firmly clamp the end of the standard section 6 or the starting section 7, so as to ensure the stability of the standard section 6 and the starting section 7 during the transmission process.To prevent it from loosening or falling off, a standard section 6 is movably installed in the transmission device 5, and a standard slide rail 601 is symmetrically installed above the standard section 6, which provides a guide for the movement of the mobile device 8, so that the mobile device 8 can move smoothly along the standard slide rail 601. A standard card plate 602 is fixedly installed at one end of the standard section 6, and a card slot 603 is opened at the other end. The standard card plate 602 is adapted to the size of the card slot 603. A connecting column 604 is adapted to be installed in the card slot 603 and the standard card plate 602. Multiple standard sections 6 can be connected in sequence through the connecting column 604 to form a required length. A number of standard card teeth 605 are evenly installed below the standard section 6. These standard card teeth 605 match the main transmission gear 506 and the auxiliary transmission gear 509 in the transmission device 5. The standard section 6 is combined to realize the smooth transmission of the standard section 6. One end of the standard section 6 is connected to the starting section 7. The starting slide rail 701 is symmetrically installed above the starting section 7, which also provides guidance for the movement of the moving device 8. A starting card plate 702 is fixedly installed at one end of the starting section 7. The starting card plate 702 is adapted to the card slot 603 of the standard section 6, which is convenient for connecting with the standard section 6. A limit plate 703 is fixedly installed at the other end of the starting section 7, which can prevent the starting section 7 from excessive movement during the transmission process and ensure the position accuracy of the starting section 7. A number of starting card teeth 704 are evenly installed below the starting section 7, which cooperate with the main transmission gear 506 and the auxiliary transmission gear 509 in the transmission device 5 to realize the transmission of the starting section 7. The moving device 8 is movably installed above the standard section 6 and the starting section 7. The mobile device 8 includes a mobile plate 801 movably placed above the standard section 6 and the starting section 7, and mobile wheels 802 are symmetrically installed below the mobile plate 801. The mobile wheels 802 are adapted to the standard slide rail 601 and the starting slide rail 701, so that the mobile plate 801 can move freely and smoothly on the standard section 6 and the starting section 7. A wiring tube 803 is fixedly installed on one side of the mobile plate 801 for connecting the power connector of the telescopic wire plate 1001 to realize the power supply to the mobile plate 801 and the transmission of measurement data. Mobile shafts 804 are installed on both sides of the mobile plate 801, and a mobile card plate 805 is fixedly installed on the surface of the mobile shaft 804. A measuring groove 806 is fixedly installed on one side of the mobile card plate 805, and a displacement sensor is installed in the measuring groove 806 for accurately measuring the movement. The displacement change of the plate 801 provides accurate data support for measuring the cross-sectional dimensions of the river channel. A measuring device 9 is movably installed on one side of the mobile device 8. The measuring device 9 includes a measuring plate 901 movably placed in a measuring groove 806. A drainage groove 902 is evenly opened in the middle of the measuring plate 901, which can effectively prevent water accumulation from affecting the measurement accuracy during the measurement process. A measuring wheel 903 is installed below the measuring plate 901. The measuring wheel 903 contacts the bottom of the riverbed. The height change of the riverbed can be measured in real time by rolling the measuring wheel 903. A safety plate 904 is fixedly installed above the measuring plate 901. The safety plate 904 is larger than the measuring groove 806, which can prevent the measuring plate 901 from escaping from the measuring groove 806, thereby ensuring the stability and reliability of the measurement process. First, the operator pushes the device and uses the roller 2 under the frame 1 to move the device to the river channel position to be measured. After reaching the designated position, the fixed shaft 301 is rotated. The rotation of the fixed shaft 301 drives the fixed plate 302 to rotate synchronously. Then, by operating the control device, which can be a control panel integrated inside the device or a handheld control terminal connected wirelessly, the fixed drill bit 303 is controlled to rotate downward along the fixed hole 306 and gradually penetrate into the soil with the thread 304 on its surface. As the fixed drill bit 303 continues to penetrate deeper, the device is firmly fixed at the measurement position to ensure that it will not move during the subsequent measurement process. After the device is fixed, the operator rotates the placement shaft 402, opens the cover plate 403 of the placement box 401, takes out the starting section 7 from the placement box 401, and slowly extends the end of the starting section 7 with the limit plate 703 into the transmission groove 502. Then, the transmission motor 504 is started by the control device, and the transmission motor 504 drives the transmission gear 505 to rotate. The transmission gear 505 drives the driven gear 508 to rotate through the transmission belt 507, thereby making the main transmission gear 506 and the auxiliary transmission gear 509 run synchronously. The main transmission gear 506 and the auxiliary transmission gear 509 contact with the starting tooth 704 under the starting section 7, and the starting section 7 is smoothly transmitted along the transmission groove 502. When the starting section 7 is transmitted to the appropriate position, the telescopic clamping shaft 1002 on the inner wall of the clamping box 10 extends out to firmly clamp the end of the starting section 7 to ensure that the starting section 7 remains stable in subsequent operations; Next, the operator takes out several standard sections 6 from the placement box 401, aligns one end of the first standard section 6 with the card slot 603 with the starting card plate 702 of the starting section 7, and then inserts the connecting column 604 to firmly connect the standard section 6 with the starting section 7. After the connection is completed, the transmission motor 504 is started again through the control device, and the main transmission gear 506 and the auxiliary transmission gear 509 are in contact with the standard card teeth 605 under the standard section 6, and the connected standard section 6 is transmitted and moved along the transmission slot 502. According to the same method, the standard section 6 is repeatedly connected and transmitted, and the length of the entire measurement structure is gradually increased so that it can cross the river surface and meet the measurement requirements of different river widths. After the standard section 6 and the starting section 7 are connected and transferred to the appropriate position, the mobile plate 801 is placed above the standard section 6, so that the moving wheel 802 below the mobile plate 801 accurately falls into the standard slide rail 601. At this time, the mobile plate 801 can move freely on the standard section 6. Then, the power connector in the telescopic wire plate 1001 is connected to the wiring tube 803 on one side of the mobile plate 801 to provide power support for the mobile plate 801 and establish a transmission channel for measurement data; Next, the measuring plate 901 is placed in the measuring groove 806 of the moving plate 801, and the measuring wheel 903 below the measuring plate 901 is ensured to be in full contact with the bottom of the riverbed. When placing the measuring plate 901, it is important to keep the measuring plate 901 level to ensure the accuracy of the measurement. After the installation is completed, the accelerometer and displacement sensor are calibrated and debugged through the control device to ensure that they can accurately measure the moving speed of the moving plate 801 and the ups and downs of the measuring plate 901. After the debugging is completed, the operator starts the movement of the moving plate 801 through the control device. The accelerometer monitors the moving speed of the moving plate 801 in real time and transmits the speed data to the control device. As the moving plate 801 moves, the measuring plate 901 also moves. Since the riverbed surface may be undulating, the measuring plate 901 will be adjusted up and down according to the shape of the riverbed. At this time, the displacement sensor in the measuring slot 806 will accurately monitor the fluctuation of the measuring plate 901 and transmit these data to the control device in real time. The control device draws a line graph of the river section by reducing the data transmitted by the accelerometer and the displacement sensor at a certain scale. By analyzing and processing the line graph, the operator can accurately obtain the dimensional information of the river section, including the width and depth of the river and the undulation of the riverbed. During the measurement process, if a more detailed measurement of a specific area is required, the control device can be used to adjust the moving speed and position of the moving plate 801 to achieve accurate measurement of the area. After the measurement work is completed, the operator first stops the movement of the moving plate 801 through the control device, then pulls out the power connector of the telescopic wire plate 1001 from the wiring tube 803, then takes out the measuring plate 901 from the measuring slot 806 and puts it into the placement box 401, then starts the reverse rotation of the transmission motor 504 through the control device, and retracts the standard section 6 and the starting section 7 into the placement box 401 in turn. During the retraction process, the telescopic clamping shaft 1002 of the clamping box 10 releases the clamping of the standard section 6 and the starting section 7 to ensure that they can be smoothly retracted; After the standard section 6 and the starting section 7 are retracted, the transmission motor 504 is turned off, the placement shaft 402 is rotated, and the cover 403 of the placement box 401 is closed. Finally, the fixed drill bit 303 is reversed by operating the control device to withdraw the fixed drill bit 303 from the soil. The operator pushes the device and uses the roller 2 to move the device to a designated storage location for proper storage for next use.
