Description

Technical Field

[0001] This utility model relates to the field of hydrological survey equipment technology, and in particular to a rapid survey device for the circulation of waterways in bends based on a mobile platform. Background Technology

[0002] The circulation structure of waterways, especially bend waterways, has a significant impact on ship navigation safety, waterway maintenance, and hydraulic engineering design. Therefore, accurate and efficient surveying of waterway circulation data is an important foundational task.

[0003] In existing survey practices, acoustic Doppler current profilers and measurement sensors are usually mounted on survey vessels for operation. However, traditional sensor installation methods require drilling or welding permanent or semi-permanent modifications to the hull to install fixed brackets. This method is not only cumbersome and time-consuming, but also damages the hull. It is particularly infeasible for temporarily rented vessels, which greatly limits the rapid deployment capability of survey equipment and its adaptability to different hulls.

[0004] Furthermore, in order to comprehensively analyze the three-dimensional structure of the bend circulation, it is necessary to obtain flow velocity data at different water depths. Some existing surveying devices are usually fixed in measurement depth after installation, or have a very limited adjustment range. It is difficult to make flexible and wide-range depth adjustments according to the actual water depth and surveying needs, resulting in incomplete survey data. At the same time, when the measuring sensor moves underwater, especially in the complex water conditions of the bend area, it may collide with rocks and debris on the bottom, or get entangled in aquatic plants, ropes, etc. This not only interrupts the measurement work, but also causes permanent damage to the expensive sensor, increasing the risk and cost of operation.

[0005] Therefore, this utility model proposes a rapid survey device for curved waterway circulation based on a mobile platform to address the shortcomings of existing technologies. Utility Model Content

[0006] In view of the problems existing in the waterway surveying device, such as poor compatibility with different ship hulls, cumbersome and time-consuming installation process, unstable connection, inconvenient underwater surveying depth adjustment, and sensor damage, this utility model aims to provide a mobile platform-based rapid surveying device for curved waterway circulation with an improved structure that can effectively solve the above problems.

[0009] Furthermore, the fixed cover is assembled by being fixedly connected to the base plate of the adjustment mechanism. A T-shaped sliding plate is fixed to the bottom of the base plate of the adjustment mechanism, and the T-shaped sliding plate is assembled with the slide rail fixed to the bottom of the hull by a sliding engagement.

[0010] Preferably, a plurality of rubber strips for increasing clamping friction are fixedly connected to the inner wall of the clamping plate facing the fixing plate.

[0011] Preferably, a rubber block for cushioning is fixedly connected to the fixing post, and a limiting block for preventing the clamping plate from sliding excessively is also provided on the fixing post.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0026] Example: Please refer to Figures 1 to 4This utility model embodiment provides a rapid survey device for curved waterway circulation based on a mobile platform, including a hull 1 as a mobile platform, a side-mounted bracket mechanism 7 for installing measuring sensors 5, and an adjustment mechanism 8 for adjusting the position. A slide rail 805 is fixedly connected to the bottom of the hull 1, and a mounting slot 2 for installing detectors 6 is opened on the top of the hull 1. Lifting handles 3 for lifting operations are fixedly connected to both the front and rear sides of the hull 1. A turbine 4 for providing displacement power to the hull 1 is fixedly installed on the outer side wall of the hull 1. The adjustment mechanism 8 includes a base plate 802, and a T-shaped sliding plate 804 is fixedly connected to the bottom of the base plate 802. The T-shaped sliding plate 804 slides in cooperation with the slide rail 805 at the bottom of the hull 1 to realize the horizontal position adjustment of the entire survey device under the hull 1. The side-mounted bracket mechanism 7 is fixedly connected to the base plate 802 of the adjustment mechanism 8. The side-mounted bracket mechanism 7 is used to detachably install and fix a fixing plate 709 on which the measuring sensors 5 are fixed, thereby stably suspending the measuring sensors 5 under the hull 1.

[0027] Please refer to Figure 2 , Figure 3 and Figure 4 The hangar support mechanism 7 includes a fixing cover 708, which is integrally mounted on the bottom of the base plate 802 of the adjustment mechanism 8. A guide post 701 is fixedly connected to the inner wall of the fixing cover 708 via a limiting plate 705. A clamping plate 704 is movably sleeved on the fixing post 701, allowing the clamping plate 704 to slide along the axis of the fixing post 701. A limiting block 703 is also provided on the fixing post 701 to prevent the clamping plate 704 from detaching from the fixing post 701 during sliding. A rubber block 702 is also fixedly connected to the end of the fixing post 701 facing the fixing plate 709. The rubber block 702 provides cushioning during clamping, preventing damage to components due to rigid contact. A corresponding tenon and mortise groove is provided on the clamping plate 704. 706, while the fixing plate 709 is integrally formed with a tenon plate 707 that matches the shape and size of the tenon groove 706. In the assembled state, the fixing plate 709 is inserted between the two clamping plates 704. By moving the clamping plates 704, the tenon plate 707 on the fixing plate 709 is embedded and locked into the tenon groove 706 of the clamping plate 704. This tenon-and-mortise locking method ensures the stability and reliability of the connection of the fixing plate 709 when subjected to water flow impact. Multiple rubber strips 710 are also fixedly connected to the inner wall of the clamping plate 704 facing the fixing plate 709. The rubber strips 710 can increase the static friction between the fixing plate 709 and the fixing plate 709 when clamped, and form a wrap around the fixing plate 709 to prevent the fixing plate 709 from accidentally slipping off.

[0028] In a preferred embodiment, in order to achieve depth adjustment of the measuring sensor 5 in the vertical direction, a telescopic vertical lifting rod 801 is fixedly connected to the lower end of the fixing plate 709, and the measuring sensor 5 is fixedly installed at the end of the vertical lifting rod 801 away from the fixing plate 709. By controlling the extension length of the vertical lifting rod 801, the underwater survey depth of the measuring sensor 5 can be changed.

[0029] As another preferred embodiment, to provide effective physical protection for the underwater measurement sensor 5, please refer to... Figure 1 and Figure 3 A protective cage 803 is coaxially installed on the outside of the measuring sensor 5. The protective cage 803 is a mesh or grid structure, which can effectively prevent the measuring sensor 5 from colliding with underwater rocks or getting entangled by seaweed or debris when the hull 1 moves.

[0030] As a preferred implementation method, in order to achieve the collection and positioning of survey data, please refer to... Figure 1 A detector 6 is fixedly installed in the mounting slot 2 opened on the top of the hull 1. The detector 6 can integrate a GPS positioning module and a data recording unit.

[0031] As a preferred embodiment, to facilitate the handling and deployment of the entire device by operators on the shore or at the dock, please refer to... Figure 1 Both the front and rear sides of the hull 1 are fixedly connected to lifting handles 3, which facilitate manual operation.

[0032] Working principle: Before conducting channel circulation survey operations, the operator first checks the integrity of the hull 1 and confirms that the detector 6 in the installation slot 2 and the measuring sensor 5 fixed on the vertical lifting rod 801 are firmly installed. Then, by lifting the lifting handles 3 on the front and rear sides of the hull 1, the entire survey device is moved to the water area to be surveyed. The installation of the measuring sensor 5 is very convenient. The operator aligns the fixing plate 709, which is connected to the vertical lifting rod 801 and the measuring sensor 5, with and inserts it into the gap between the two clamping plates 704 in the hangar bracket mechanism 7. Then, the clamping plate 704 is pushed inward, and the clamping plate 704 will slide along the fixing post 701. During this process, the tenon plate 707 on the fixing plate 709 will be accurately embedded and locked in the tenon groove 706 of the clamping plate 704, forming a stable tenon and tenon locking structure. At the same time, the rubber strip 710 on the inner wall of the clamping plate 704 will tightly wrap and press the side of the fixing plate 709, further increasing the friction and preventing slippage. The rubber block 702 on the fixing post 701 plays a buffering role to avoid damage to the components during clamping. The entire installation process does not require complicated tools and achieves rapid assembly. After the survey operation begins, the operator activates the turbine 4 on the outer wall of the hull 1 to provide power to the hull 1, enabling the hull 1 to move flexibly in the curved waterway. When the designated survey section or measuring point is reached, if it is necessary to adjust the horizontal position of the sensor, the T-shaped sliding plate 804 at the bottom of the base plate 802 can be pushed to slide along the slide rail 805 at the bottom of the hull 1, thereby achieving precise lateral positioning of the entire survey device. If it is necessary to survey circulation data at different depths, the operator can control the vertical lifting rod 801 to extend downwards, driving the measuring sensor 5 to descend to the preset depth. The measuring sensor 5 begins to collect water flow data. At the same time, the detector 6 located on the top of the hull 1 records the current geographical coordinates. Throughout the movement and measurement process, the protective cage 803 wrapped around the measuring sensor 5 can effectively resist the impact of underwater rocks and the entanglement of aquatic plants, ensuring the continuity of the measurement work and the safety of the equipment. By repeating the above operation at different locations and depths, the three-dimensional circulation data of the entire curved channel can be obtained quickly and accurately.
