Description

Technical Field

[0001] This utility model relates to a device for underwater movement testing technology inside a metal cabin, and in particular to an underwater towing movable device. Background Technology

[0002] The underwater environment is vast and complex. With the advancement of industry and technology, higher demands are being placed on the inspection, testing, and data acquisition of underwater structures. Various underwater mobile tests and inspections are required in enclosed or confined metal compartments such as ship ballast tanks and underwater storage tanks.

[0003] Currently, there are two main types of common underwater mobile detection methods: one is operated by divers using handheld equipment, which is not only inefficient and limited by operating time, but also has poor positioning accuracy and difficulty in ensuring data consistency; the other is to use underwater robots (ROVs), but their mobility is limited in narrow, enclosed cabins, their operation is unstable, and their purchase and operation costs are high.

[0004] Furthermore, some existing track-based mobile devices often mount the drive motor directly onto the moving trolley. This structure causes the power cable to be dragged along with the trolley, and long-term reciprocating motion can easily cause cable wear, tangling, or even breakage, posing a safety hazard. At the same time, the moving motor increases the load and inertia of the trolley, hindering precise control and rapid start-stop. More importantly, this structure places extremely high demands on the watertightness of the motor; if the seal fails in deep water or during long-term operation, it will lead to the failure of the entire system.

[0005] Therefore, there is an urgent need in the field for a mobile device that can adapt to underwater environments, operate stably and reliably, has precise position control, and is easy to perform repeatable tests within a fixed test range. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides an underwater towing mobile device, including: a watertight motor, a trolley, a driven wheel, a driving wheel, a timing belt, a guide rail frame, and a control box;

[0007] The watertight motor is fixedly installed at one end of the guide rail frame, and its output shaft is coaxially connected to the drive wheel; the driven wheel is located at the other end of the guide rail frame, and forms a closed-loop transmission circuit with the drive wheel through the synchronous belt;

[0008] The synchronous belt is arranged longitudinally along the guide rail frame, and its two ends are fixed to the front and rear sides of the trolley respectively, for pulling the trolley to move back and forth along the guide rail; the upper part of the guide rail frame is provided with a guide rail extending along its length direction, and the trolley is fitted onto the guide rail by a wheel assembly and moves along it in a directional manner.

[0009] The control box is located outside the guide rail frame and is electrically connected to the watertight motor via a cable. It is used to control the start, stop, speed, direction, and position of the trolley.

[0010] In one embodiment of this utility model, the circulating loop consisting of the watertight motor, the driving wheel, the driven wheel, and the synchronous belt is used to adjust the moving speed and positioning of the trolley through the control box; and the guide rail frame is an integral welded structure.

[0011] In one embodiment of this utility model, the trolley includes a trolley frame, a left wheel, a right wheel, and an auxiliary wheel;

[0012] The left wheel protrudes at both ends to be engaged with the guide rail to prevent the trolley from shifting left or right; the auxiliary wheel is engaged at the lower end of the guide rail to prevent the trolley from tipping over.

[0013] In one embodiment of this utility model, the guide rail frame includes a bottom support frame, a guide rail, and a blocking member;

[0014] The bottom support frame is equipped with a mounting plate at its bottom, which is fixed to the test site by bolts; the guide rail is a standard I-beam; the blocking components are located at both ends of the guide rail to limit the running range of the trolley.

[0015] In one embodiment of this utility model, the control box panel is provided with an LCD touch control screen, which is used to display the position, speed and fault information of the trolley in real time, and to control the operation of the trolley through touch operation.

[0016] Compared with the prior art, the above-mentioned technical solution of this utility model has the following advantages: The underwater towable mobile device of this utility model adopts a fixed watertight motor and synchronous belt drive, avoiding the wear and safety hazards caused by the cable being towed by the trolley; the unique wheel and auxiliary wheel design of the trolley effectively prevents deviation and overturning during operation. At the same time, through the control box with integrated touch screen, the trolley can realize inching, continuous, constant speed and precise positioning operation, and can execute complex automatic programs, greatly improving the automation level and data consistency of the detection. Moreover, the core components have watertight characteristics, and the whole is made of anti-corrosion materials, ensuring that the device can work stably for a long time in harsh underwater environments. Its modular design allows the trolley platform to flexibly carry different detection equipment, making it highly versatile. Attached Figure Description

[0022] like Figure 1 As shown, this embodiment provides an underwater towable mobile device, whose core components include: a watertight motor 1, a trolley 2, a driven wheel 3, a driving wheel 4, a synchronous belt 5, a guide rail frame 6, and a control box 7.

[0023] The watertight motor 1 serves as the power source and is bolted to one end of the guide rail frame 6. Its output shaft is directly connected to the drive wheel 4. This motor has a reliable sealing device, can operate stably in an underwater environment for extended periods, and can rotate in both forward and reverse directions.

[0024] The driven wheel 3 is mounted at the other end of the guide rail frame 6 and is connected to the driving wheel 4 via a synchronous belt 5, thus forming a closed-loop cyclic transmission circuit. The synchronous belt 5 is arranged longitudinally along the guide rail frame 6, and its two ends are fixed to the front and rear sides of the trolley 2 by fasteners. When the watertight motor 1 is started, it drives the driving wheel 4 to rotate, which in turn pulls the trolley 2 to move via the synchronous belt 5.

[0025] The trolley 2 is entirely made of steel, possessing sufficient strength and corrosion resistance. For example... Figure 2 As shown, the trolley 2 specifically includes a trolley frame 21, a left wheel 22, a right wheel 23, and an auxiliary wheel 24. The left wheel 22 has flanges at both ends, which securely engage with the guide rail 62, effectively preventing the trolley from shifting left or right during operation. The auxiliary wheel 24 is located below the guide rail 62, cooperating with the lower flange of the guide rail to prevent the trolley from tipping over during movement and ensure stable operation. Above the trolley 2 is a mounting platform, where various detection sensors or testing devices can be installed according to different testing requirements.

[0026] The guide rail frame 6 serves as the main mounting base for the entire device, such as Figure 3As shown, the device includes a bottom support frame 61, a guide rail 62, and blocking components 63. The bottom support frame 61 is an integrally welded structure with high rigidity. Its bottom is welded with a mounting plate with bolt holes, allowing the entire device to be securely fixed to the test site using bolts. The guide rail 62 is made of standard I-beams, with a smooth surface and high strength, providing good running conditions for the trolley wheels. The blocking components 63 are installed at both ends of the guide rail 62 as physical limits, preventing the trolley from accidentally derailing during operation.

[0027] The control box 7 provides a stable power supply and control signal to the watertight motor 1. Its panel integrates an LCD touchscreen control screen, allowing operators to easily control all operating states of the trolley via the touchscreen. The control box 7 is directly connected to the stationary watertight motor 1 via a cable, avoiding potential wear and tear and malfunctions caused by the cable being dragged along with the trolley.

[0028] The novel underwater towable mobile device in this embodiment is mainly made of stainless steel or other high-performance corrosion-resistant materials to cope with corrosion in the harsh underwater environment.

[0029] The underwater towable mobile device described in this embodiment is operated on-site using a touchscreen to control the trolley. The operation instructions are as follows:

[0030] (1) After powering on, click the "Move Car" button on the menu page to enter the car's main interface.

[0031] (2) Return to zero: Press the return to zero button, and the trolley will automatically move in the negative direction at a certain speed until it stops at the zero position, and the trolley position will be set to zero.

[0032] (3) Jog: Set the target speed, press the jog button to move the car at the preset speed, and release the jog button to stop the car. The interface displays the car's real-time speed and position.

[0033] (4) Continuous operation: A target speed can be set. When the run button is pressed, the car will move at the preset speed. When the stop button is pressed or the boundary is reached, the car will stop moving. The interface displays the car's real-time speed and position.

[0034] (5) Automatic target operation: Set the target speed and target position. After pressing the run button, the car will run automatically according to the set target and speed until it reaches the set target position and then stops automatically. The interface displays the car's real-time speed and position.

[0035] (6) Automatic Program Execution: Set the target speed, target position, and dwell time. Press the run button. The message "Program is running" will be displayed, and the program will begin running. The car will first automatically return to zero and display "Returning to Zero," then the program segment will begin execution. The interface displays the car's real-time speed, position, and program execution information (which segment and minute it is in). After the automatic program ends, the interface will display "Program execution completed." During automatic program execution, information such as start time, end time, and execution time can be displayed.

[0036] (7) Alarm information: The interface can display necessary fault or warning information such as front and rear limit switches, zero position trigger, driver fault, motor fault, etc.

[0037] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
