[0033] Example 1
[0034] During a stage performance, two sliding platforms move horizontally towards each other along the lifting stage, stopping once they reach their designated positions. Actors then board these platforms to perform. The existing structure cannot achieve precise positioning of the sliding platforms, nor can it guarantee that they will stop at their designated locations. This could result in the distance between the two platforms being too large or too small, affecting subsequent performances.
[0035] In view of this, the present invention provides an underwater positioning device, comprising: a lifting stage 100, a lifting component 200, and a translating platform 300. The lifting component 200 is connected to the lifting stage 100 and can rise and fall synchronously with the lifting stage 100. The translating platform 300 is slidably connected to the lifting stage 100. The lifting component 200 includes a first positioning structure protruding from the top of the lifting stage 100, and the translating platform 300 is correspondingly provided with a second positioning structure. The translating platform 300 can stop operating when the second positioning structure abuts against the first positioning structure.
[0036] During a stage performance, the lifting stage 100 descends below the water surface, and the lifting assembly 200 descends synchronously with it. The translation platform 300 slides horizontally along the lifting stage 100, with its bottom underwater and its top above the water surface. When the translation platform 300 moves to the point where the second positioning structure abuts against the first positioning structure underwater, it immediately stops moving, thus achieving precise underwater positioning. After reaching its designated position, the performers board the translation platform 300 to begin their performance.
[0037] The underwater positioning device enables the translation platform 300 to be precisely positioned underwater, allowing it to move along the lifting stage 100 to the designated position and stop, thus ensuring the smooth progress of subsequent performances.
[0038] In an optional embodiment, the lifting assembly 200 further includes a movable pulley 210 and a lifting support rod 220. The movable pulley 210 is connected to the lifting stage 100 via a steel wire rope 230. The bottom of the lifting support rod 220 is connected to the movable pulley 210, and the top of the lifting support rod 220 is connected to the first positioning structure.
[0039] Please see Figure 1 The right side of the movable pulley 210 is fixed to the lifting stage 100 via a steel wire rope 230. The bottom of the lifting support rod 220 is fixed to the movable pulley 210, and the lifting support rod 220 passes through the lifting stage 100. The top of the lifting support rod 220 is equipped with a first positioning structure. As the lifting stage 100 descends below the water surface, the lifting assembly 200 descends synchronously with it. After the lifting stage 100 reaches its final position, due to the action of the movable pulley 210, the lifting assembly 200 will only descend half its travel distance, and the entire lifting assembly 200 will be hidden below the water surface. When the translation platform 300 slides along the lifting stage 100 until the second positioning structure abuts against the first positioning structure underwater, the translation platform 300 immediately stops moving, achieving precise underwater positioning of the translation platform 300.
[0040] In an optional embodiment, the lifting stage 100 is provided with a through groove 110, and the lifting support rod 220 passes through the through groove 110 and is connected to the first positioning structure.
[0041] Please see Figure 3 The lifting support rod 220 passes vertically through the through groove 110, and the first positioning structure is fixed to the top of the lifting support rod 220. When the lifting stage 100 is lowered into position, the first positioning structure will be hidden below the water surface, thus ensuring the performance effect.
[0042] In an optional embodiment, the first positioning structure includes a first positioning block 240, which is vertically connected to the lifting support rod 220.
[0043] Please see Figure 2 The first positioning block 240 and the lifting support rod 220 are arranged perpendicularly to each other, so that the first positioning block 240 has a larger contact area when it comes into contact with the second positioning structure, thus ensuring the accurate positioning of the underwater positioning device.
[0044] In an optional embodiment, the lifting stage 100 is provided with a slide rail along its length, and the bottom of the translational platform 300 is provided with multiple traveling wheels 310, which slide in cooperation with the slide rail.
[0045] Please see Figure 1 The translation platform 300 is equipped with two wheels 310 on each side of its bottom. The wheels 310 can slide along the slide rails of the lifting stage 100, enabling the translation platform 300 to slide horizontally along the lifting stage 100. When the lifting stage 100 is lowered into position, only the bottom of the translation platform 300 is below the water surface, while the rest is above the water surface, making it convenient for performers to board the translation platform 300 for performance.
[0046] In an optional embodiment, the translation platform 300 is equipped with a drive motor, which is connected to the traveling wheels 310 via a transmission connection.
[0047] The rotation of the traveling wheels 310 can be controlled by the drive motor inside the translation stage 300, thereby controlling the sliding or stopping of the translation stage 300 along the lifting stage 100.
[0048] In an optional embodiment, the side of the translation platform 300 is provided with a notch, and the second positioning structure is disposed in the notch.
[0049] Please see Figure 2 The translation stage 300 has a notch or groove on the side facing the first positioning block 240, and the second positioning structure is set in the notch or groove, so that the second positioning structure is hidden inside the translation stage 300, which also ensures the performance effect.
[0050] In an optional embodiment, the second positioning structure includes a second positioning block 320 and a connecting wheel 330. The second positioning block 320 is fixedly disposed in the notch groove, and the connecting wheel 330 is installed on the bottom of the second positioning block 320. The connecting wheel 330 can abut against the first positioning structure.
[0051] Please see Figure 3 The inner side of the second positioning block 320 is fixedly connected to the translation stage 300, thereby fixing it in the notch. A connecting wheel 330 is fixedly provided at the bottom of the second positioning block 320. When the left end of the translation stage 300 slides horizontally along the lifting stage 100 to the first positioning block 240, the connecting wheel 330 will abut against the first positioning block 240.
[0052] In an optional embodiment, the second positioning block 320 is provided with a limit switch, which is connected to the drive motor signal.
[0053] After the connecting wheel 330 abuts against the first positioning block 240, the limit switch receives a signal and then activates. After receiving the signal from the limit switch, the drive motor controls the traveling wheel 310 to stop rotating, thereby controlling the translation platform 300 to stop moving and achieving precise positioning of the translation platform 300 underwater.
[0054] In an optional embodiment, the translation platform 300 is provided with multiple steps 340.
[0055] Please see Figure 2 The multi-level staircase 340 allows actors to easily climb onto the platform at the top of the 300 moving platform for performances.
[0056] The underwater positioning device in this embodiment operates as follows:
[0057] During a stage performance, the lifting stage 100 descends below the water surface, and the first positioning block 240 descends synchronously below the water surface with the lifting stage 100. After the lifting stage 100 is in position, the translation platform 300 slides horizontally along the lifting stage 100. When the translation platform 300 slides to the first positioning block 240, the connecting wheel 330 will abut against the first positioning block 240. After receiving the signal, the limit switch will activate, and after receiving the signal from the limit switch, the drive motor will control the traveling wheel 310 to stop rotating, thereby controlling the translation platform 300 to stop moving, achieving precise underwater positioning of the translation platform 300.
[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
