Description

Technical Field

[0001] This utility model relates to a hydrological surveying device, specifically a cable-suspended remote-controlled vehicle body structure, belonging to the technical field of hydrological surveying device. Background Technology

[0002] In the field of hydrological surveying, fieldwork is the norm. Hydrological workers face extremely complex natural environments and diverse river scenarios for extended periods. From a climatic perspective, the scorching sun in summer can easily lead to heatstroke among personnel and high-temperature equipment malfunctions. In the snowy and windy river environment of winter, low temperatures can not only cause frostbite to workers but may also freeze equipment components, affecting operation. Furthermore, severe weather with wind and rain can directly interfere with the accuracy and safety of the surveying operations. From a river scenario perspective, whether it is a turbulent river or a gentle stream, hydrological workers need to conduct flow measurement work. The complexity of the operating scenarios places extremely high demands on the surveying equipment.

[0003] In the process of measuring the flow of small and medium-sized rivers, existing measuring equipment has obvious shortcomings and is difficult to meet the actual operational needs. For example, in the remote-controlled rope traction pulley disclosed in announcement number CN202098932U, although it can change the transportation of the rope from the ground to the air, without considering the terrain, saving a lot of manpower and material resources, greatly improving the construction progress and reducing the operating cost, this technical solution is only suitable for high-voltage transmission line construction. The currently commonly used unmanned remote-controlled boat equipped with ADCP (Acoustic Doppler Current Profiler) solution can achieve unmanned operation, but it has two major problems: First, the cost is too high. The purchase, maintenance and construction of supporting systems of unmanned remote-controlled boats require a lot of investment, which puts a heavy economic burden on grassroots hydrological measurement units. Second, the speed is difficult to meet the requirements. In small and medium-sized rivers with very low flow velocity, the navigation speed of unmanned remote-controlled boats is not matched with the measurement accuracy, making it impossible to effectively complete the flow data collection of the entire river channel and prolonging the operation time.

[0004] Another commonly used manual traction method also has significant drawbacks. The manual traction method relies on operators to work on both sides of the river or on the bank. On the one hand, speed control is difficult. The traction speed is unstable due to factors such as the operator's strength, experience, and water flow resistance, which can easily lead to deviations in the ADCP data collected and affect the accuracy of flow calculation. On the other hand, crossing the river is time-consuming, especially in scenarios where the river is of moderate width but deep. There are safety risks or inefficiencies in crossing the river for the test personnel. In addition, manual traction not only consumes a lot of physical strength but also requires repeated adjustments to the traction path, which seriously reduces the test efficiency and may even cause safety risks due to operator error. Summary of the Invention

[0005] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing technologies are too simplistic. Specifically, the purpose of this utility model is to solve the aforementioned shortcomings of existing technologies by proposing a cable-suspended remote-controlled vehicle body structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cable-suspended remote-controlled vehicle body structure includes a power supply system, a control system, and a power system.

[0013] As a further improvement of this utility model: the peripheral walls of both the driven wheel and the driving wheel are provided with grooves, and the inner wall of the transmission belt is provided with protrusions, which engage with the grooves.

[0014] The beneficial effects of this utility model are:

[0024] 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.

[0025] Example 1, as Figures 1 to 5 As shown, a cable-suspended remote-controlled vehicle body structure includes a power supply system, a control system, and a power system. The power supply system and the control system are both located on the power system. The power system includes a housing and a cover 20, a rotary connector 21, a stainless steel movable connecting plate 22, and a screw bolt 23. The top of the housing and the cover 20 is connected and fixed to a stainless steel clamp plate 17 by a connecting bolt 18. Two stainless steel clamp plates 17 are symmetrically arranged, and a fixing bolt 14 is connected between the two stainless steel clamp plates 17. The rotary connector 21 is connected between the housing and the cover 20 and the stainless steel movable connecting plate 22. The screw bolt 23 passes through the stainless steel movable connecting plate 22 and is fixed to the stainless steel clamp plate 17. Two bearing seats 11 are symmetrically arranged on both sides of the stainless steel clamp plate 17. A shaft 16 is rotatably connected to the center of the bearing seat 11. The shaft 16 is located on the top of the housing and the cover 20, and a pulley 15 is coaxially fixed on the shaft 16. The pulley 15 is located between two adjacent stainless steel clamp plates 17.

[0026] The power supply system includes an operation control module 1, a battery power detection module 2, a 12V lithium battery 3, and a power switch 4. The operation control module 1, the battery power detection module 2, and the 12V lithium battery 3 are all located inside the enclosure and cover 20. The power switch 4 is located on one side of the bottom of the enclosure and cover 20 and is electrically connected to the operation control module 1, the battery power detection module 2, and the 12V lithium battery 3.

[0027] The power system also includes a motor mounting base 9, a motor 10, a driven wheel 12, a transmission belt 13, and a driving wheel 19. The motor mounting base 9 is fixed to the outer wall of the housing and the housing cover 20. The motor 10 is fixed inside the motor mounting base 9. The driving wheel 19 is coaxially fixed to the output shaft of the motor 10. The driven wheel 12 is coaxially fixed to one end of the shaft 16. The transmission belt 13 is sleeved on the outside of the driven wheel 12 and the driving wheel 19. A load hook 5 is provided at the bottom center of the housing and the housing cover 20.

[0028] The control system includes a charging interface 6, a connecting cable 7, and an antenna 8. The charging interface 6 is located on the other side of the bottom of the box and the box cover 20, and the charging interface 6 is electrically connected to the 12V lithium battery 3 through the connecting cable 7. The antenna 8 is located on one side of the box and the box cover 20 and is electrically connected to the operation control module 1.

[0029] The box body and box cover 20 are slidably connected to the guide system. The guide system includes a cross-river steel wire rope 29, a rope tensioner 30, and riverbank fixing piles 31. Two riverbank fixing piles 31 are fixed one-to-one on both sides of the riverbank. The cross-river steel wire rope 29 is set between two adjacent riverbank fixing piles 31. The rope tensioner 30 is set between one of the riverbank fixing piles 31 and the cross-river steel wire rope 29.

[0030] In this utility model, the guiding system uses a combination of a cross-river steel wire rope 29, a rope tensioner 30, and a riverbank fixed pile 31 to construct a stable suspended track above the river, allowing the remote-controlled vehicle to escape the influence of water flow resistance and stably tug the trimaran in low-flow environments; the load hook 5 at the bottom of the vehicle body is directly connected to the ADCP device, and in conjunction with the pulley 15 and transmission belt 13 of the power system, uniform linear motion is achieved, ensuring the accuracy of flow data acquisition;

[0031] The control system achieves wireless signal transmission with the operation control module 1 through the antenna 8. With the integrated design of the power switch 4 and the charging interface 6, it supports plug-and-play and convenient charging. The DC power supply mode avoids the limitations of AC power wiring, and the battery power detection module 2 monitors the battery life in real time, meeting the mobility requirements of field operations.

[0032] The power system adopts a simple transmission chain of "motor 10 - drive wheel 19 - transmission belt 13 - driven wheel 12 - shaft 16 - pulley 15", without complex hydraulic or gearbox structures; the groove diameter of pulley 15 is precisely matched with the cross-river steel wire rope 29, and the trolley moves smoothly through the rotation of pulley 15. Compared with manual traction, the remote-controlled car can run automatically at a constant speed, which greatly shortens the river crossing test time, significantly improves the work efficiency, and also saves a lot of costs.

[0033] Example 2, as Figures 1 to 5As shown, in addition to all the technical features included in Embodiment 1, this embodiment also includes:

[0034] Both the driven wheel 12 and the driving wheel 19 have grooves on their peripheral walls, and the inner wall of the transmission belt 13 has protrusions that engage with the grooves. The engagement of the protrusions with the grooves prevents the transmission belt 13 from sliding on the driven wheel 12 and the driving wheel 19 due to insufficient friction when transmitting power.

[0035] It should be noted that this utility model is also equipped with a remote control system, which is wirelessly connected to the control system. The remote control system includes a remote control housing, a remote control antenna 24, an LCD screen 25, a remote control control module 26, a 7V lithium battery 27, and control buttons 28. The remote control antenna 24 is located on the top of the remote control housing, the LCD screen 25 is embedded on the front surface of the remote control housing, the remote control control module 26 is located inside the remote control housing, the 7V lithium battery 27 is fixed to the bottom of the remote control control module 26, and the control buttons 28 are located on the front surface of the remote control housing. The remote control antenna 24, the LCD screen 25, the 7V lithium battery 27, and the control buttons 28 are all electrically connected to the remote control control module 26.

[0036] When using this hydrological survey equipment, first fix the riverbank fixed piles 31 at corresponding positions on both sides of the river, connect the cross-river steel wire rope 29 between the two fixed piles, adjust the tension of the steel wire rope through the tensioner 30 to build a stable suspension track, and then slide the box and box cover 20 together onto the cross-river steel wire rope 29 through the pulley 15 to complete the equipment assembly.

[0037] Then, turn on the power switch 4. The battery power detection module 2 monitors the power of the 12V lithium battery 3 in real time. The operator sends a signal through the remote control device. The antenna 8 receives the signal and transmits it to the operation control module 1. The remote control system controls the motor 10 to start. The output shaft of the motor 10 drives the drive wheel 19 to rotate. The drive wheel 12 is driven to rotate through the transmission belt 13, thereby driving the shaft 16 and pulley 15 to roll on the cross-river steel wire rope 29. Due to the precise matching between the pulley groove of the pulley 15 and the diameter of the steel wire rope 29, a large friction force is generated, and the remote control vehicle moves smoothly along the steel wire rope.

[0038] The trimaran equipped with ADCP is connected to the load hook 5 at the bottom of the vehicle body. The remote control vehicle pulls the trimaran to move laterally along the river at a constant speed, thus avoiding the influence of water flow resistance and achieving stable linear motion. During the movement, the ADCP device collects flow velocity and flow data at different locations in the river, ensuring the accuracy and stability of the data collection.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
