Description

Technical Field

[0001] This utility model belongs to the field of motor testing technology, specifically relating to an underwater testing device for surfboard motors. Background Technology

[0002] As the core power component of an electric surfboard, the performance and reliability of the surfboard motor directly affect the surfboard's usability and safety. Therefore, during production or maintenance, it is necessary to conduct underwater operation tests on surfboard motors to simulate real-world usage environments and test key indicators such as waterproofing, operational stability, and power output.

[0003] Currently, existing surfboard motor testing devices typically employ a fixed testing platform structure, placing the motor in a water tank for testing. The motor is fixed above the tank or in shallow water using a bracket for operation testing. Because the testing platform height is fixed, the motor cannot be fully immersed to different depths, making it difficult to simulate the dynamic water pressure environment of actual surfing and affecting test accuracy. Furthermore, the clamping mechanisms of existing devices are usually only compatible with a single motor model; for surfboard motors of different diameters, the clamps need to be changed, resulting in cumbersome operation and high costs. Therefore, we have designed an underwater surfboard motor testing device to provide an alternative technical solution to the aforementioned problems. Utility Model Content

[0023] 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.

[0024] Reference Figure 1-6 An underwater testing device for a surfboard motor includes a water storage test tank 1, a vertical support frame 2 mounted on the top of the water storage test tank 1, a vertical lifting plate 3 installed at the top inside the vertical support frame 2, a rectangular test platform 5 installed at the bottom of the vertical lifting plate 3, vertical connecting columns 4 fixed at the four corners of the bottom of the vertical lifting plate 3, the bottom of the vertical connecting columns 4 being fixedly connected to the rectangular test platform 5, and a lifting mechanism for lifting the rectangular test platform 5 being installed on the top of the vertical lifting plate 3.

[0025] The bottom of the rectangular test platform 5 is equipped with a limiting mechanism for fixing the motor;

[0026] A rectangular mounting plate 6 is fixed on one side of the vertical support frame 2. A test device 7 is set on the top of the rectangular mounting plate 6. The test device 7 consists of a Hall effect current sensor and a laser speed sensor. The Hall effect current sensor can detect the surfboard motor in real time, measure the input current of the surfboard motor, and reflect the current change of the surfboard motor.

[0027] The laser speed sensor detects the mark on the surfboard motor shaft by reflecting laser light, accurately outputting the speed without the need for physical connection devices underwater, thus reducing sealing complexity.

[0028] The lifting mechanism includes a drive motor 11, which is fixed to the top of the vertical lifting plate 3. A worm gear 12 is fixed to the output end of the drive motor 11. A worm wheel 13 is meshed with the outer side of the worm gear 12. A vertical rotating column 14 is rotatably connected to the bottom of the worm wheel 13 through a bearing. The vertical rotating column 14 passes through the interior of the vertical lifting plate 3 and is fixedly connected to the vertical lifting plate 3. A vertical threaded rod 10 is threadedly connected to the interior of the worm wheel 13. A horizontal connecting plate 9 is rotatably connected to the bottom of the vertical threaded rod 10 through a bearing. Vertical fixing plates 8 are fixed to both ends of the horizontal connecting plate 9. The vertical fixing plates 8 are located inside the vertical support frame 2 and are fixedly connected to the vertical support frame 2.

[0029] Both sides of the interior of the vertical fixed plate 8 are fixed with arc-shaped blocks. The vertical connecting column 4 passes through the interior of the arc-shaped block and is slidably connected to the arc-shaped block. Through the setting of the arc-shaped block, the vertical connecting column 4 can slide vertically on the arc-shaped block, so that the vertical connecting column 4 can slide vertically on one end of the vertical fixed plate 8. The movement of the vertical connecting column 4 allows the position and height of the rectangular test platform 5 and the vertical lifting plate 3 to be adjusted.

[0030] The vertical rotating column 14 has a vertical through hole inside, the diameter of which is larger than the diameter of the vertical threaded rod 10, so that the vertical threaded rod 10 can rotate inside the vertical rotating column 14.

[0031] Here, the operation of the drive motor 11 causes the worm gear 12 to rotate, and the rotation of the worm gear 12 causes the worm wheel 13 to rotate. Through the threaded connection between the worm wheel 13 and the vertical threaded rod 10, the vertical lifting plate 3 and the rectangular test platform 5 can be vertically lifted and lowered, and the vertical connecting column 4 can slide vertically inside the arc block, so that the position and height of the rectangular test platform 5 can be adjusted. When the rectangular test platform 5 is lowered to the bottom of the water storage test tank 1, the surfboard motor can be immersed in the liquid inside the water storage test tank 1 for the purpose of testing the surfboard motor.

[0032] The limiting mechanism includes a handwheel 17, one end of which is fixed with a transverse rotating rod 18, and one end of which is fixed with a transverse threaded rod 19. One end of the transverse threaded rod 19 is rotatably connected to a support block via a bearing. The top of the support block is fixedly connected to a rectangular test platform 5. A transverse sliding plate 20 is threadedly connected to the outer side of the transverse threaded rod 19. Both ends of the transverse sliding plate 20 are rotatably connected to an oblique rotating column 21 via pins. The end of the oblique rotating column 21 away from the transverse sliding plate 20 is rotatably connected to a longitudinal pushing block 22 via a pin. A transverse driving plate 16 is fixed to the end of the longitudinal pushing block 22 away from the oblique rotating column 21. Both ends of the inner side of the handwheel 17 are fixed with arc-shaped restraint straps 15.

[0033] The rectangular test platform 5 has a rectangular through hole inside. The arc-shaped restraint strap 15 is located inside the rectangular through hole and is slidably connected to the rectangular test platform 5 through the rectangular through hole. The rectangular through hole allows the arc-shaped restraint strap 15 to slide vertically inside the rectangular test platform 5.

[0034] A dovetail slider is fixed to the top of the longitudinal push block 22. A dovetail groove adapted to the dovetail slider is opened inside the rectangular test platform 5. The rectangular test platform 5 and the longitudinal push block 22 are slidably connected by the dovetail slider and the dovetail groove. The longitudinal push block 22 can slide at the bottom of the rectangular test platform 5 by the setting of the dovetail slider and the dovetail groove. The sliding of the longitudinal push block 22 allows the transverse drive plate 16 to move. The two transverse drive plates 16 move in opposite directions, thereby allowing the arc-shaped restraint belt 15 to fix the surfboard motor and prevent the surfboard motor from detaching from the rectangular test platform 5 during operation.

[0035] Here, the surfboard motor is placed on top of the rectangular test platform 5. By turning the handwheel 17, the horizontal rotating rod 18 can be rotated. The rotation of the horizontal rotating rod 18 causes the horizontal threaded rod 19 to rotate. The rotation of the horizontal threaded rod 19 causes the horizontal sliding plate 20 to slide at the bottom of the rectangular test platform 5. The sliding of the horizontal sliding plate 20 causes the vertical pushing block 22 to slide inside the rectangular test platform 5 through the oblique rotating column 21. The two vertical pushing blocks 22 move in opposite directions. The movement of the two vertical pushing blocks 22 causes the horizontal driving plate 16 to move. The movement of the horizontal driving plate 16 allows the arc-shaped restraint strap 15 to clamp surfboard motors of different diameters, thereby improving the applicability of this device.

[0036] Working principle: The surfboard motor is placed on top of the rectangular test platform 5. By turning the handwheel 17, the horizontal rotating rod 18 can be rotated. The rotation of the horizontal rotating rod 18 causes the horizontal threaded rod 19 to rotate. The rotation of the horizontal threaded rod 19 causes the horizontal sliding plate 20 to slide at the bottom of the rectangular test platform 5. The sliding of the horizontal sliding plate 20 causes the vertical pushing block 22 to slide inside the rectangular test platform 5 through the oblique rotating column 21. The two vertical pushing blocks 22 move in opposite directions. The movement of the two vertical pushing blocks 22 causes the horizontal driving plate 16 to move. The movement of the horizontal driving plate 16 allows the arc-shaped restraint strap 15 to clamp surfboard motors of different diameters, thereby improving the applicability of this device.

[0037] The operation of the drive motor 11 causes the worm gear 12 to rotate, which in turn causes the worm wheel 13 to rotate. Through the threaded connection between the worm wheel 13 and the vertical threaded rod 10, the vertical lifting plate 3 and the rectangular test platform 5 can be raised and lowered vertically, and the vertical connecting column 4 can slide vertically inside the arc-shaped block, allowing the position and height of the rectangular test platform 5 to be adjusted. When the rectangular test platform 5 is lowered to the bottom of the water storage test tank 1, the surfboard motor can be immersed in the liquid inside the water storage test tank 1 for testing purposes.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
