DETAILED DESCRIPTION

[0026] The following is a detailed description of embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments in the implementation manner are intended to be used to explain the present invention and should not be construed as limiting the present invention.

[0027] References in this specification to "one embodiment" or "an example" or "an example" mean that a particular feature, structure, or characteristic described in conjunction with the embodiment itself may be included in at least one embodiment of the present patent disclosure. The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0028] This embodiment provides an underwater lifting waterproof laser device, such as Figure 1 and Figure 2 As shown, it includes a lifting platform 11 and a laser lamp 10. The underwater lifting waterproof laser equipment also includes an adjusting mechanism 12. The laser lamp 10 is rotatably connected to the lifting platform 11 through the adjusting mechanism 12. The adjusting mechanism can drive the laser lamp 10 to rotate around a first axis, and the adjusting mechanism can drive the laser lamp 10 to rotate around a second axis. The first axis intersects with the second axis. The length direction of the first axis is consistent with the lifting direction of the lifting platform 11. The rotation angle of the laser lamp 10 around the second axis is smaller than the rotation angle around the first axis.

[0029] By setting the lifting platform 11, the laser lamp 10 can adjust its working height as needed. By setting the adjustment mechanism 12 between the laser lamp 10 and the lifting platform 11, the adjustment mechanism 12 is rotatably connected to the laser lamp 10, and the adjustment mechanism 12 is rotatably connected to the top of the lifting platform 11. It can be understood that the adjustment mechanism 12 has a fixed state, that is, the adjustment mechanism 12 and the laser lamp 10 can be relatively fixed, and the laser lamp 10 and the lifting platform 11 are relatively fixed, so as to ensure that the laser beam of the laser lamp 10 can be stably output when in use. In the non-fixed state, driven by the adjustment mechanism 12, the laser lamp 10 can rotate with multiple degrees of freedom relative to the lifting platform 11, so as to adjust the irradiation direction or angle of the laser beam, realize the precise adjustment of the laser beam, and adapt to different work requirements. The underwater lifting waterproof laser device of the utility model realizes the flexible adjustment of the height, direction and angle of the laser beam through the synergistic effect of the lifting platform 11, the laser lamp 10 and the adjustment mechanism 12, thereby improving the applicability of the laser device.

[0030] It should be noted that the maximum rotation angle of the laser lamp 10 around the first axis is 360°, thereby ensuring the projection adjustment range of the laser lamp 10. Since the light-emitting surface of the laser lamp 10 does not need to face the lifting platform 11, the rotation angle of the laser lamp 10 around the second axis is less than 360°, that is, the rotation angle of the laser lamp 10 around the second axis is less than the rotation angle around the first axis.

[0031] It is understandable that the above-mentioned laser equipment can be used on the ground or underwater. In order to realize the underwater operation of the laser equipment, the housing of the laser lamp 10 and the housing of the motor 13 in this embodiment can both adopt waterproof housings, thereby improving the sealing of the laser equipment and preventing water from entering the interior of the laser lamp 10 and the motor 13 during underwater operation. Among them, the waterproof housing meets the IP68 grade. Similarly, the adjustment mechanism 12 and the lifting platform 11 of this embodiment can be made of stainless steel to avoid rust caused by long-term underwater operation.

[0032] Preferably, the first axis and the second axis are perpendicular to each other, so as to improve the connection stability between the adjustment mechanism and the laser lamp. It can be understood that the intersection of the first axis and the second axis means that the first axis and the second axis are not parallel.

[0033] In this embodiment, the specific structure of the adjustment mechanism 12 is not particularly limited, as long as the adjustment mechanism 12 can drive the laser lamp 10 to rotate with multiple degrees of freedom relative to the lifting platform 11. Optionally, the adjustment mechanism 12 includes a first connecting member 121 and a second connecting member 122, the first connecting member 121 is rotatably connected to the top of the lifting platform 11, and the second connecting member 122 is connected between the first connecting member 121 and the laser lamp 10.

[0034] The first connecting member 121 can rotate relative to the lifting platform 11 to drive the second connecting member 122 and the laser lamp 10 to rotate around the first axis; the second connecting member 122 can rotate relative to the first connecting member 121 to drive the laser lamp 10 to rotate around the second axis.

[0035] Through the cooperation of the first connecting member 121 and the second connecting member 122, the laser lamp 10 can rotate around the first axis and the second axis, that is, multi-degree-of-freedom rotation, thereby increasing the adjustment range of the laser lamp 10, so that the laser beam of the laser lamp 10 can be projected to any area of ​​the stage without moving the underwater lifting waterproof laser device. In addition, the first connecting member 121 and the second connecting member 122 are simple in parts, easy to install and use, and the user can adjust the position and angle of the laser lamp 10 by adjusting the first connecting member 121 and the second connecting member 122.

[0036] Optionally, the first connecting member 121 includes a first bottom plate 1211 and two first side plates 1212, and the first bottom plate 1211 is connected between the two first side plates 1212; the second connecting member 122 includes a second bottom plate 1221 and two second side plates 1222, and the second bottom plate 1221 is connected between the two second side plates 1222, and the second bottom plate 1221 is connected to the laser lamp 10.

[0037] The first bottom plate 1211 is rotatably connected to the top of the lifting platform 11 so that the laser lamp 10 can rotate around a second axis, and the direction of the second axis is consistent with the thickness direction of the first bottom plate 1211 .

[0038] The two second side plates 1222 are rotatably connected to the corresponding first side plates 1212 , respectively, so that the laser lamp 10 can rotate around a first axis, and the direction of the first axis is consistent with the thickness direction of the second side plates 1222 .

[0039] The first bottom plate 1211 and the two first side plates 1212 are connected to form a first connecting member 121 in a U-shape, and the second bottom plate 1221 and the two second side plates 1222 are connected to form a second connecting member 122 in a U-shape. The U-shaped structural design enables the first connecting member 121 and the second connecting member 122 to have good stability and load-bearing capacity, thereby ensuring that the laser lamp 10 can work stably after installation and reducing problems caused by shaking or vibration. In addition, the first connecting member 121 composed of the first bottom plate 1211 and the two first side plates 1212, and the second connecting member 122 composed of the second bottom plate 1221 and the two second side plates 1222 are simple in structure and easy to operate. The projection angle of the laser lamp 10 can be adjusted by simply rotating the first connecting member 121 or the second connecting member 122.

[0040] In an optional embodiment, the adjustment mechanism 12 also includes a first positioning member 1213 and a second positioning member 1223, the first bottom plate 1211 is formed with a first adjustment hole 1211a, the first positioning member 1213 is arranged on the top of the lifting platform 11, and the first positioning member 1213 passes through the first adjustment hole 1211a; the two first side plates 1212 are respectively formed with second adjustment holes 1212a, the two second side plates 1222 are both provided with second positioning members 1223, and the second positioning members 1223 pass through the corresponding second adjustment holes 1212a.

[0041] The first positioning member 1213 cooperates with the first adjustment hole 1211 a , and the second positioning member 1223 cooperates with the second adjustment hole 1212 a , so as to limit the rotational freedom of the laser lamp 10 .

[0042] By passing the first positioning member 1213 through the first adjustment hole 1211a of the first bottom plate 1211, the rotation of the first connecting member 121 around the first axis is limited, and by passing the second positioning member 1223 through the second adjustment hole 1212a of the first side plate 1212, the rotation of the second connecting member 122 around the first axis is limited. It should be noted that the hinge between the first positioning member 1213 and the lifting platform 11 is different from the position of the first adjustment hole 1211a, and the axial direction of the hinge is coaxial with the first axis. Similarly, the axial direction of the hinge between the second positioning member 1223 and the first positioning member 1213 is coaxial with the second axis.

[0043] In a specific embodiment, the first positioning member 1213 includes a first positioning rod (not shown in the figure) and a first fastener (not shown in the figure), the first positioning rod is arranged at the top of the lifting platform 11, the first positioning rod passes through the first adjustment hole 1211a, and the first fastener is threadedly connected to the first positioning rod; the second positioning member 1223 includes a second positioning rod and a second fastener, both second side panels 1222 are provided with a second positioning rod, the second positioning rod passes through the corresponding second adjustment hole 1212a, and the second fastener is threadedly connected to the corresponding second positioning rod.

[0044] The first bottom plate 1211 can be fixed on the top of the lifting platform 11 by means of a first fastener and a first positioning rod, and the second side plate 1222 can be fixed on the corresponding first side plate 1212 by means of a second fastener and a second positioning rod.

[0045] After the first positioning rod passes through the first adjustment hole 1211a, the first fastener is sleeved on the first positioning rod, and the first bottom plate 1211 is fixed to the top of the lifting platform 11 through the threaded connection between the first fastener and the first positioning rod. Similarly, the second side plate 1222 is fixed to the corresponding first side plate 1212 through the threaded connection between the second positioning rod and the second fastener. When the angle of the laser lamp 10 needs to be adjusted, the first fastener is screwed in the opposite direction to move the first fastener away from the top of the lifting platform 11, and the restriction of the first fastener on the first bottom plate 1211 is released, so that the laser lamp 10 can rotate around the first axis. The second fastener is screwed in the opposite direction to move the second fastener away from the first side plate 1212, and the restriction of the second fastener on the second side plate 1222 is released, so that the laser lamp 10 can rotate around the second axis.

[0046] In the present utility model, there is no special limitation on the specific method of realizing multi-angle adjustment of the laser lamp 10. For example, a plurality of first adjustment holes 1211a can be opened on the first bottom plate 1211, and a plurality of second adjustment holes 1212a can be opened on the second bottom plate 1221. According to the angle to be adjusted, the first positioning member 1213 is inserted into the corresponding first adjustment hole 1211a, and the second positioning member 1223 is inserted into the corresponding second adjustment hole 1212a. Preferably, the opening of the first adjustment hole 1211a is annular, and the opening of the second adjustment hole 1212a is arc-shaped. The opening of the first adjustment hole 1211a coincides with the trajectory of the first positioning member 1213 rotating around the first axis, and the opening of the second adjustment hole 1212a coincides with the trajectory of the second positioning member 1223 rotating around the second axis.

[0047] Optionally, the lifting platform 11 includes a base 113 , a support plate 112 , and a scissor-type telescopic frame 111 connected between the base 113 and the support plate 112 , and the adjustment mechanism 12 is disposed on the support plate 112 .

[0048] By arranging the scissor-type telescopic frame 111 between the base 113 and the support plate 112 , the support plate 112 can be repeatedly moved along its thickness direction, thereby achieving the adjustment of the laser lamp 10 in the height direction.

[0049] In an optional embodiment, the scissors-type telescopic frame 111 includes two support members 1111 and a connecting rod 1112 connecting the two support members 1111. The two sides of the support members 1111 are connected to the base 113 and the support plate 112. The two support members 1111 are stacked and spaced apart along the length direction of the base 113. The support members 1111 have a folded state and an unfolded state. When the support members 1111 are switched from the folded state to the unfolded state, the support plate 112 moves away from the base 113.

[0050] By folding and unfolding the support member 1111 , the support plate 112 is repeatedly moved along its thickness direction.

[0051] Optionally, the underwater lifting waterproof laser device also includes a motor 13, which is arranged on the base 113 and connected to the connecting rod 1112; the motor 13 is used to drive the connecting rod 1112 to move the support plate 112 in a direction away from the base 113 or in a direction close to the base 113.

[0052] The motor 13 drives the connecting rod 1112, which drives the support member 1111, so that the support member 1111 gradually unfolds or folds, thereby driving the support plate 112 and the laser lamp 10 to move up and down, and realizing precise control of the lifting and lowering movement of the support plate 112 and the laser lamp 10.

[0053] In a specific embodiment, the lifting platform 11 also includes two first limit members 114 and two second limit members 115. The two first limit members 114 are both arranged on the side of the support plate 112 facing the base 113, and the two first limit members 114 are arranged opposite to each other; the two second limit members 115 are both arranged on the side of the base 113 facing the support plate 112, and the two first limit members 114 are arranged opposite to each other; the first limit member 114 is formed with a first limit hole 114a, and the second limit member 115 is formed with a second limit hole 115a.

[0054] The support member 1111 includes a first connection part 1113, a second connection part 1114, a third connection part 1115 and a fourth connection part 1116. The first connection part 1113 is hinged on the support plate 112, and the second connection part 1114 is movably disposed in the corresponding first limiting hole 114a; the third connection part 1115 is hinged on the base 113, and the fourth connection part 1116 is movably disposed in the corresponding second limiting hole 115a.

[0055] Through the cooperation between the second connection part 1114 and the first limiting hole 114a of the support member 1111, and the cooperation between the fourth connection part 1116 and the second limiting hole 115a of the support member 1111, when the support plate 112 moves toward the direction close to the base 113 under the drive of the linkage rod 1112, the second connection part 1114 abuts against one end of the first limiting hole 114a, and the fourth connection part 1116 abuts against one end of the second limiting hole 115a, and under the limiting action of the first limiting hole 114a and the second limiting hole 115a, the support member 1111 will not continue to fold. In this way, when the support member 1111 is folded to the maximum extent, there is enough space between the support plate 112 and the base 113 to place the motor 13.
