Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example: like Figures 1-8 As shown, the support frame used inside the dock for the floating dock gate provided in this embodiment includes a steel column 100, a top plate 110, a bottom plate 120, a diagonal brace 200, a mounting plate 300, a shell 400, a positioning laser generator 500, and a power supply battery 600, wherein: The steel column 100 is a solid square or round steel column. The top plate 110 and the bottom plate 120 are welded to the top and bottom of the steel column 100, respectively. The size of the top plate 110 is smaller than that of the bottom plate 120. In use, wooden blocks are placed on the top plate 110, while the bottom plate 120 is placed on the ground inside the dock. To prevent the entire support frame from tipping over, counterweights (such as stones or concrete blocks) can also be placed on the bottom plate 120.

[0021] One end of the diagonal brace 200 is welded and fixed to the outer wall of the steel column 100, and the other end of the diagonal brace 200 is welded and fixed to the base plate 120. The steel column 100 extends vertically, while the diagonal brace 200 is inclined. There are four diagonal braces 200, which are evenly distributed around the steel column 100.

[0022] Mounting plate 300 is welded to the diagonal brace 200. Specifically, the mounting plate 300 is welded between two adjacent diagonal braces 200, which further enhances the structural strength of the support frame. Housing 400 is detachably mounted on the mounting plate 300. A first through hole is provided at the top of housing 400, and a first transparent plate 410 is installed in this first through hole. Specifically, the first transparent plate 410 is fixed in the first through hole by waterproof adhesive, and the first transparent plate 410 can be a transparent plastic plate or transparent glass. It is easily understood that housing 400 is a structural component with an internal cavity.

[0023] The aforementioned positioning laser generator 500 is rotatably mounted within the aforementioned housing 400. When the positioning laser generator 500 is rotated to a vertical position, the laser emitted by the positioning laser generator 500 passes upward through the first transparent plate 410 and then shines straight upward. A power supply battery 600 is installed within the aforementioned housing 400 and is electrically connected to the aforementioned positioning laser generator 500. It is worth noting that a wireless switch is provided on the line connecting the positioning laser generator 500 and the power supply battery 600, allowing operators to remotely control the power supply to and from the positioning laser generator 500. It is easy to understand that when the positioning laser generator 500 is powered on, it emits a positioning laser.

[0024] With the above structure, the support frame supports the floating dock gate from below using steel columns 100, base plate 120, top plate 110, and wooden blocks placed on the top plate 110. The diagonal brace 200 further enhances the structural strength of the support frame. Furthermore, when the floating dock gate needs to be inspected, a marking circle can be drawn on the bottom wall of the floating dock gate. Then, the positioning laser generator 500 is rotated to vertical and connected to the power supply battery 600, causing the positioning laser generator 500 to emit a positioning laser. At this time, the positioning... The laser passes through the first transparent plate 410 and shines straight upwards. The aforementioned marking circle corresponds to the positioning laser. In this way, during the bottoming process of the pontoon dock, the diver can submerge in the water and observe whether the positioning laser is located within the corresponding marking circle to determine whether the pontoon dock is in the correct bottoming position. Moreover, the positional relationship between the marking circle and the positioning laser can be easily obtained visually, so that the diver can accurately guide the pontoon dock to the precise position. When the pontoon dock is in the precise position, the positioning laser is exactly projected into the corresponding marking circle.

[0025] It is worth noting that multiple support frames as described above need to be installed inside the dock to jointly support the floating dock gate. Each support frame is equipped with the aforementioned positioning laser generator 500. Thus, multiple marking circles need to be drawn on the floating dock gate in advance, with each marking circle corresponding to the positioning laser emitted by multiple positioning laser generators 500. Moreover, the wooden blocks placed on the top plate 110 will not block the upward-facing positioning laser. Alternatively, through holes can be made in the wooden blocks so that the positioning laser can pass through. If the wooden blocks are not placed accurately on the top plate 110, the positioning laser cannot pass through the wooden blocks. This can also help determine whether the wooden blocks are placed in the correct position on the top plate 110.

[0026] Optionally, a second through hole is provided on the side wall of the housing 400, and a second transparent plate 420 is installed in the second through hole. Specifically, the second transparent plate 420 is fixed in the second through hole by waterproof adhesive, and the second transparent plate 420 can be a transparent plastic plate or a transparent glass plate. A transparent cylinder 430 is also installed on the outer side wall of the housing 400. The transparent cylinder 430 extends horizontally and covers the second through hole. The axis of the transparent cylinder 430 is perpendicular to the axis of the second through hole, and the axis of the second through hole is also horizontal. The transparent cylinder 430 can be a structural component supported by transparent plastic or transparent glass.

[0027] When the positioning laser generator 500 is rotated to a horizontal position, the laser emitted by the positioning laser generator 500 passes through the second transparent plate 420 and enters the transparent cylinder 430 radially.

[0028] With the above structure, after the floating dock gate is seated in the dock, the positioning laser generator 500 can be driven to change from a vertical state to a horizontal state. At this time, the positioning laser generator 500 faces the second transparent plate 420. When the positioning laser generator 500 is powered on, the positioning laser emitted by it passes through the second transparent plate 420 and enters the transparent cylinder 430 radially. In this way, a long light spot parallel to the axis of the transparent cylinder 430 will be formed in front of the transparent cylinder 430. By setting the transparent cylinder 430 to a suitable height so that the long light spot coincides with the bottom or top line of the sealant layer installed at the bottom of the floating dock gate, the staff can more easily inspect the sealant layer. Specifically, the positioning laser generators 500 on multiple support frames simultaneously rotate to horizontal operation, thus forming a long light spot that can cover the length of the sealant layer. If the bottom or top line of the sealant layer does not coincide with the long light spot, it indicates that the sealant layer is damaged or there is an installation error, and adjustments are required.

[0029] Optionally, two protruding plates are provided on the outer wall of the housing 400, each with a corresponding circular hole, and the two protruding plates are respectively located on both sides of the second through hole. The two ends of the transparent cylinder 430 are respectively inserted into the circular holes on the two protruding plates. Alternatively, two clips are provided on the outer wall of the housing 400, with the two clips located on both sides of the second through hole, and the two clips respectively clamp the two ends of the transparent cylinder 430.

[0030] Optionally, a drive assembly 700 connected to the positioning laser generator 500 is further installed within the housing 400. The drive assembly 700 is used to drive the positioning laser generator 500 to rotate within the housing 400. Specifically, the drive assembly 700 includes a rotating shaft 710 and a motor 740, wherein: The rotating shaft 710 is rotatably mounted on the inner wall of the housing 400. The axial direction of the rotating shaft 710 is parallel to the transparent cylinder 430, and the central axis of the rotating shaft 710 is on the same horizontal plane as the transparent cylinder 430. A mounting bracket 720 is provided on the outer wall of the rotating shaft 710, and the positioning laser generator 500 is mounted on the mounting bracket 720. A ring tooth 730 coaxial with the rotating shaft 710 is also provided on the outer wall of the rotating shaft 710.

[0031] The motor 740 is mounted on the inner bottom wall of the housing 400. The motor 740 is electrically connected to the power supply battery 600. The circuit connecting the motor 740 and the power supply battery 600 drives the motor 740 to rotate in both directions. A wireless switch is also installed on the circuit connecting the motor 740 and the power supply battery 600 to control the forward and reverse rotation of the motor 740. A gear 750 is connected to the shaft of the motor 740, and the gear 750 meshes with the ring gear 730. Thus, when the motor 740 rotates forward by a certain angle, it can rotate the horizontal positioning laser generator 500 to a vertical position; conversely, when the motor 740 rotates in reverse by a certain angle, it can rotate the vertical positioning laser generator 500 to a horizontal position.

[0032] In fact, this embodiment simply uses the forward and reverse rotation function of the motor 740 to drive the gear 750 to rotate forward and reverse, thereby driving the ring gear 730 and the rotating shaft 710 to rotate forward and reverse, which can drive the mounting bracket 720 and the positioning laser generator 500 mounted on it to rotate forward and reverse, thereby allowing the orientation of the positioning laser generator 500 to switch back and forth between the first transparent plate 410 and the second transparent plate 420.

[0033] Of course, the aforementioned drive assembly 700 can also be, for example, a rotary handle. In this case, one end of the aforementioned rotating shaft 710 outputs the housing 400 and is connected to the aforementioned rotary handle. Rotating the handle drives the aforementioned rotating shaft 710 to rotate in both directions. In this case, a locking bolt needs to be screwed onto the rotary handle. When locked, the locking bolt presses against the outer wall of the aforementioned housing 400. Moreover, the aforementioned first mark and second mark are on the outer wall of the aforementioned housing 400, and a mark is provided on the aforementioned rotary handle. When the mark is aligned with the first mark, it indicates that the positioning laser generator 500 has rotated to face the first transparent plate 410. When the mark is aligned with the second mark, it indicates that the positioning laser generator 500 has rotated to face the second transparent plate 420.

[0034] Optionally, the aforementioned mounting bracket 720 includes a connecting rod 721 and a collar 722, wherein: One end of the connecting rod 721 is welded and fixed to the outer wall of the rotating shaft 710, and the connecting rod 721 is located in the middle of the rotating shaft 710. The connecting rod 721 extends radially along the rotating shaft 710. The aforementioned collar 722 is welded and fixed or integrally formed at the other end of the connecting rod 721. The collar 722 is adapted to the positioning laser generator 500, which is inserted into the collar 722, and the tail end of the positioning laser generator 500 overlaps the outer wall of the rotating shaft 710. Alternatively, a stop bolt can be screwed onto the collar 722 to press the positioning laser generator 500 into the collar 722.

[0035] Of course, as another implementation of this embodiment, the aforementioned collar 722 can also be replaced by a clamp, which can be used to clamp the positioning laser generator 500. Regardless of the type of mounting bracket 720, it is acceptable as long as it can hold the positioning laser generator 500 and ensure that the positioning laser generator 500 extends radially along the rotation axis 710.

[0036] Optionally, the aforementioned housing 400 includes a box body 440 and a cover plate 450, wherein: The box 440 has an installation opening formed through the side opposite to the steel column 100. The first through hole is opened in the top wall of the box 440, and the second through hole is opened in the side wall of the box 440. The cover plate 450 is detachably connected to the box body 440, and the cover plate 450 seals the mounting opening. Specifically, multiple connecting ears 442 are welded or heat-fused to the outer wall of the box body 440, and multiple connecting plates 452 are integrally formed on the outer edge of the cover plate 450. Each of the multiple connecting ears 442 corresponds to one of the multiple connecting plates 452, and the corresponding connecting ears 442 and connecting plates 452 are bolted and fixed together by a first bolt 470. To prevent water leakage at the junction of the cover plate 450 and the box body 440, a sealing ring 460 surrounding the mounting opening is also installed between the box body 440 and the cover plate 450. In this embodiment, the multiple connecting ears 442 are evenly distributed around the mounting opening.

[0037] A first circular shaft 451 is provided on one side wall of the cover plate 450 near the inner wall of the housing 440. A second circular shaft 441 coaxial with the first circular shaft 451 is provided on the inner wall of the housing 440. Both ends of the rotating shaft 710 have central holes. The first circular shaft 451 and the second circular shaft 441 are rotatably inserted into the two central holes, thereby rotatably mounting the rotating shaft 710 inside the housing 400. When the cover is opened, the rotating shaft 710 and the positioning laser generator 500 on it can be easily removed.

[0038] In addition, the outer wall of the aforementioned box 440 is provided with a side wing plate 443, which is flush with the bottom wall of the aforementioned box 440. The side wing plate 443 is bolted and fixed to the aforementioned mounting plate 300 by a second bolt 444, thereby detachably mounting the housing 400 onto the aforementioned mounting plate 300.

[0039] To prevent the power supply battery 600 from affecting the operation of the positioning laser generator 500, in this embodiment, a vertical partition 445 is provided inside the housing 440, and the internal space of the housing 440 is divided into a first cavity and a second cavity by the partition 445. The drive assembly 700 and the positioning laser generator 500 are both installed in the first cavity, and the power supply battery 600 is installed in the second cavity. A through-hole for wires is provided on the partition 445. Alternatively, a circuit board can be installed in the second cavity, integrating the wireless switch, signal receiving module, power supply lines, etc., while the power supply battery 600, motor 740, and positioning laser generator 500 are all electrically connected to the circuit board.

[0040] In fact, the aforementioned housing 400 and its internal positioning laser generator 500, drive assembly 700, and power supply battery 600 can be understood as a laser generation box. Furthermore, in this embodiment, "sitting on the ground" refers to the process where the floating dock gate, after being unloaded from the dock entrance, is moved into the dock by hoisting or towing and settled on the dock's ground.

[0041] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope described in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
