Description

Technical Field

[0001] This utility model relates to the field of inland waterway surveying technology, specifically to an inclined rigid sweeping bed frame suitable for inland waterways. Background Technology

[0002] In inland waterway surface measurement and channel dimension verification, rigid sweeper frames are a common channel maintenance device. However, traditional sweeper frames must remain perpendicular to the water surface during operation, and their attitude needs to be corrected by external force to maintain this state. Therefore, in order to cope with the extremely high stress the entire sweeper frame bears, the entire sweeper frame structure is extremely heavy and difficult to disassemble, and it is impossible to adjust the sweeper frame's water depth in a timely manner according to changes in water level. Utility Model Content

[0003] This utility model addresses the needs of existing rigid sweeper frames used in inland waterways by providing an inclined rigid sweeper frame suitable for inland waterways. By eliminating redundant structures used to keep the vertical rods perpendicular to the water surface, many limitations on the structural strength of the sweeper frame are eliminated, resulting in an overall weight reduction of the device. At the same time, it can better adjust the tilt angle and water entry length in a timely manner during sweeping, thus better coping with elevation changes caused by water level variations and adapting to the needs of inland waterway maintenance.

[0004] To achieve the above-mentioned technical features, the purpose of this utility model is as follows: an inclined rigid sweeping bed frame suitable for inland waterways includes a navigation buoy boat. A hinged fixing frame is symmetrically fixed on the top of the foredeck of the navigation buoy boat. A crossbar is rotatably installed between the hinged fixing frames. Vertical bars are installed at both ends of the crossbar through sleeves. A sweeping bar is fixed at the bottom end of the vertical bar. The sweeping bar is located below the bottom of the navigation buoy boat. A winch traction mechanism is installed between the sweeping bar and the navigation buoy boat. A hydrofoil structure that applies downward pressure is installed on the vertical bar and near the end where the sweeping bar is located.

[0005] Preferably, the vertical rod is fitted inside the sleeve and can be slidably adjusted inside the sleeve; Furthermore, locking nuts are installed on the vertical rod and on both sides of the sleeve to lock the position after the vertical rod position adjustment is completed.

[0006] Preferably, the crossbar is mounted inside the hinged frame via bearings.

[0007] Preferably, the sleeve is fixed to the crossbar by welding.

[0008] Preferably, the winch traction mechanism includes a winch base fixed to both sides of the top of the navigation buoy, a winch fixed to the top of the winch base, a steel cable wound on the drum of the winch, and the end of the steel cable connected to a sweeping rod.

[0009] Preferably, the vertical poles are located on both sides of the navigation aid boat and are spaced a certain distance apart.

[0010] Preferably, the hydrofoil structure is divided into three parts, including a load-bearing shaft installed on the inner wall of the vertical rod, a main wing in front of the load-bearing shaft, a flap behind the load-bearing shaft, and a streamlined bottom surface and an arched top surface after the main wing and flap are combined.

[0011] Preferably, the sweeping rod is mounted on the end of the vertical rod via a sweeping rod bracket.

[0012] The present invention has the following beneficial effects: 1. This utility model changes the working mode of the rigid sweeping frame, abandons the redundant structure used to keep the vertical rod perpendicular to the water surface and downward, frees up many limitations on the structural strength of the sweeping frame, realizes the overall weight reduction of the device, and can also better realize timely adjustment of the tilt angle and water entry length during the sweeping process to cope with the elevation changes caused by water level changes.

[0013] 2. This utility model uses an inclined and rigid sweeping bed frame to be installed on the navigation mark boat used for waterway maintenance, and is hinged and fixed to the foredeck, thus ensuring smooth rotation and adjustment of the vertical rod.

[0014] 5. The vertical rod of this utility model consists of a pair of parts installed at both ends of the horizontal rod of the hinged fixed frame. The length of the vertical rod is twice the maximum scanning depth of the sweeping bed frame, and there is a base for installing an adjustable hydrofoil at the bottom 1 / 10; there is also a base for installing the sweeping rod at the bottom. The sweeping rod is a vulnerable part of the entire device and is installed at the bottom of the vertical rod for scanning structural feedback.

[0015] 6. The adjustable hydrofoil of this invention is mounted on the base of the vertical rod and can be pre-adjusted to the appropriate angle as needed. The hydrofoil itself consists of two parts: a main wing and flaps. The tilt angle of the main wing and the release position of the flaps can be adjusted to achieve different lift schemes. When the entire device is running, the fluid velocity above the hydrofoil is less than the fluid velocity below the hydrofoil. The hydrofoil provides a downward force, which makes the vertical rod exert a force greater than the upward component of the fluid resistance.

[0016] 7. This utility model includes two sets of adjustable-length steel cables and winches installed on both sides of the navigation buoy, with the steel cables connected to the bottom of the vertical pole. The winches control the length of the steel cables to provide additional tension, ensuring the stability of the vertical pole's working angle.

[0017] 8. When the entire device of this utility model is running, the hydrofoil state and the length of the vertical rod in the water are set according to the sweeping depth requirements. Under the combined action of the hydrofoil and the steel cable, the vertical rod maintains its posture in the water at a preset angle.

[0018] 9. When the water level changes, this utility model adjusts the measurement depth by changing the winch's winding and unwinding scale and adjusting the extension length of the vertical rod inside the sleeve.

[0019] 10. With the above-described structure, when the sweeping rod contacts an underwater obstacle, the sweeping rod receives an external force, which is transmitted to the vertical rod, causing the vertical rod to quickly change its tilt angle, minimizing structural deformation and ensuring that the sweeping frame itself is not damaged. After passing the obstacle, the vertical rod will automatically return to the preset working tilt angle under the action of the hydrofoil. Attached Figure Description

[0027] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0028] Example 1: Reference Figure 1-5A type of inclined rigid sweeping bed frame suitable for inland waterways includes a navigation buoy 1. Hinged fixing frames 7 are symmetrically fixed to the top of the foredeck of the navigation buoy 1. A crossbar 8 is rotatably mounted between the hinged fixing frames 7. Vertical rods 2 are mounted to both ends of the crossbar 8 via sleeves 9. A sweeping rod 5 is fixed to the bottom end of the vertical rod 2, located below the bottom of the navigation buoy 1. A winch traction mechanism is installed between the sweeping rod 5 and the navigation buoy 1. A hydrofoil structure 3 that applies downward pressure is installed on the vertical rod 2 and near the end where the sweeping rod 5 is located. By eliminating redundant structures used to keep the vertical rods perpendicular to the water surface, many limitations on the structural strength of the sweeping bed frame are eliminated, resulting in overall weight reduction of the device. Simultaneously, it allows for better timely adjustment of the tilt angle and water entry length during sweeping, thus better addressing elevation changes caused by water level variations and adapting to the needs of inland waterway maintenance. By using a hinged horizontal bar 8 and sleeve 9 to install the vertical bar 2, the vertical bar 2 can rotate around the horizontal bar 8 and can slide and extend inside the sleeve 9. This changes the traditional vertical installation of the vertical bar 2 to an inclined installation, effectively simplifying its installation structure and making it well adaptable to different measurement depths.

[0029] Furthermore, the vertical rod 2 is fitted inside the sleeve 9 and can be slidably adjusted within the sleeve 9. This sliding installation structure ensures that the vertical rod 2 can be adjusted in position within the sleeve 9.

[0030] Furthermore, locking nuts are installed on the vertical rod 2 and on both sides of the sleeve 9 to lock the position of the vertical rod 2 after the position adjustment is completed. These locking nuts can be used to lock the position of the vertical rod 2 to prevent positional changes during subsequent measurement.

[0031] Furthermore, the crossbar 8 is mounted inside the hinged fixing frame 7 via bearings. This bearing mounting structure ensures that the crossbar 8 can rotate stably.

[0032] Furthermore, the sleeve 9 is fixed to the crossbar 8 by welding. This fixing method ensures that the sleeve 9 can be reliably fixed to the crossbar 8.

[0033] Furthermore, the winch traction mechanism includes winch bases fixed to both sides of the top of the navigation beacon boat 1. A winch 10 is fixed to the top of the winch base, and a steel cable 4 is wound on the drum of the winch 10. The end of the steel cable 4 is connected to the sweeping rod 5. The winch traction mechanism described above can traction the sweeping rod 5. This not only fixes the position of the sweeping rod 5, but also facilitates subsequent adjustment of the tilt angle of the vertical rod 2.

[0034] Furthermore, the vertical rods 2 are positioned on both sides of the navigation aid boat 1 and maintained at a certain distance. This arrangement ensures the smooth rotation of the vertical rods 2 and prevents them from causing obstruction.

[0035] Furthermore, the hydrofoil structure 3 is divided into three parts: a load-bearing shaft 302 mounted on the inner wall of the vertical rod 2; a main wing 301 in front of the load-bearing shaft 302; and a flap 303 behind the load-bearing shaft 302. The bottom surface of the main wing 301 and the flap 303 combined has a streamlined structure, and the top surface has an arc-shaped structure. Through the aforementioned hydrofoil structure 3, which possesses detailed hydrodynamic features, it provides the most basic overall lift. The load-bearing shaft in the middle transfers the force generated by the hydrofoil structure 3 to the vertical rod 2, while also adjusting the overall pitch angle of the main wing. The flaps, mounted behind the load-bearing shaft, can be adjusted as needed to ensure that the hydrofoil's lift can be maintained even at low speeds, guaranteeing the normal operation of the entire device.

[0036] Furthermore, the sweeping rod 5 is mounted on the end of the vertical rod 2 via the sweeping rod bracket 6. This mounting structure ensures the reliable and secure installation of the sweeping rod 5.

[0037] Example 2: The working process of this utility model: When the bed sweeping frame is not in use, the device is disassembled into individual components for storage. When a bed sweeping operation is to be performed, the individual components are assembled and the device is put into working condition.

[0038] First, the riveted base of the hinged fixing frame is installed on the foredeck of the navigation beacon. Then, the crossbar is installed on the top of the riveted base. Finally, the hydrofoil structure is installed on the vertical bar and the relevant settings of the hydrofoil structure are adjusted.

[0039] After installing the articulated mounting bracket, bring the buoy boat to the shore with the front end facing the bank. Place the buoy boat against the bank slope and install the vertical pole. Then, install the hydrofoil structure and sweeper in place, and connect the steel cable to both ends of the sweeper. Once the entire installation is complete, use a cable winch to lift the vertical pole into the air. Move the buoy boat to a deep water area, release the steel cable, and lower the vertical pole into the water. Restart the winch to tighten the cable, allowing the vertical pole to rotate around the horizontal bar to its working position.

[0040] After the sweeper frame is assembled, the navigation boat uses a slow-speed drive to slowly perform the sweeping operation. The water flow, with its varying velocities on the upper and lower surfaces of the hydrofoil structure and the influence of the flaps, generates a downward force, allowing the entire vertical rod to resist fluid resistance. By adjusting the specific settings of the hydrofoil structure, the downward force of the fluid is made greater than the upward component of the fluid resistance, and the steel cable provides additional tension to ensure that the sweeper is at a controllable working water depth.

[0041] When the sweeping bar of the sweeping bed frame collides with an underwater obstacle, the sweeping bar will cause the vertical bar to rotate backward and jump up or directly break the sweeping bar at the bottom of the sweeping bed frame without causing damage to other parts of the sweeping bed frame.

[0042] After the sweeper frame is damaged or the sweeping operation is completed, first adjust the vertical bar upwards, then flip the vertical bar forward around the horizontal bar to raise the sweeper bar out of the water. In this state, the sweeper frame can then be used to replace or remove the sweeper bar.

[0043] Example 3: The working principle of this utility model: The working state of the vertical rod 2 is completely different from that of a traditional sweeping bed frame. The vertical rod 2 does not need to be kept perpendicular to the water surface like a traditional sweeping bed frame, and the vertical rod itself does not require additional rigid structure reinforcement. By changing the angle between the vertical rod 2 and the horizontal rod 8 in the working state, the local stress on the vertical rod 2 and the horizontal rod 8 is greatly reduced, avoiding the possibility of local deformation and structural collapse caused by excessive flow velocity in traditional sweeping bed frames. It also ensures measurement accuracy and adjustability to real-time changes in water level during the measurement process.

[0044] The hydrofoil structure 3 replaces the rigid fixation of the vertical rod 2 in the traditional sweeper frame. Through the hydrodynamic design of the hydrofoil structure 3, the vertical rod 2 of the inclined rigid sweeper frame can achieve dynamic force balance under the action of the hydrofoil structure 3 and the steel cable 4 during ship towing. By replacing the rigid fixation of the traditional sweeper frame with the force combination of the hydrofoil structure 3 and the steel cable 4, the flow velocity limitations of the rigid sweeper are greatly expanded, and material strength limitations are avoided.

[0045] Because of the working principle of the inclined vertical rod 2, the execution depth of the sweeping bed is determined by the inclination angle and water immersion depth of the vertical rod 2. Therefore, by utilizing this working principle, it is only necessary to adjust the steel cable 4 by the winch 10 and simultaneously adjust the vertical degree of freedom of the vertical rod 2 to make corresponding adjustments to the inclined sweeping bed frame while keeping the attitude of the hydrofoil structure 3 unchanged, thereby reducing measurement errors.
