Description

Technical Field

[0001] This utility model relates to the field of dam technology, and more specifically, to a mobile drainage and diversion platform for dam construction with adjustable height. Background Technology

[0002] A dam is a water-retaining structure that blocks the flow of water in rivers or channels and raises the water level to achieve multiple functional requirements.

[0003] The existing publication number CN204753517U discloses a gate body and dam equipped with a diversion pipe. The inlet of the diversion pipe is located on the water-facing side of the gate body, in an area below half the height of the gate body; the outlet of the diversion pipe is located on the backwater side of the gate body, in an area above the height of the inlet of the diversion pipe and below the designed water-blocking level of the gate body. Using the diversion pipe and gate body of this invention, water in front of the gate body can flow from the upper layer to the lower layer, thereby increasing the dissolved oxygen content of the lower layer water and effectively improving the water quality in front of the gate. Its structure is simple, low in cost, and very easy to maintain; at the same time, it can enrich the flow pattern and shape of the gate body, resulting in a very good landscape effect. The inventors discovered the following problems with the existing technology during the development of this invention:

[0004] During the construction of existing dams, it is necessary to divert water sources. However, due to the construction process during the completion of the dam's foundation, the outlet of the dam's working face is often narrow and has many obstacles. The fixed outlet is easily blocked, resulting in high-speed water flow. High-speed water flow can cause slope instability, foundation hollowing, or material loss.

[0005] Therefore, a mobile drainage and diversion platform with adjustable height for dam construction is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a mobile drainage and diversion platform for dam construction with adjustable height, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a mobile drainage and diversion platform for dam construction with adjustable height, comprising a dam body and a mobile lifting double gate platform. A dam observation top is provided above the dam body, and several sets of drainage channels are provided through the center of the dam body. Limiting sliding frames are provided on both sides of the drainage channels, and the mobile lifting double gate platform is provided inside the limiting sliding frames. The mobile lifting double gate platform includes a bidirectional gate and a reinforced pushing gate, and a reinforced pushing gate is provided below the bidirectional gate.

[0008] Preferably, the bidirectional gate includes an inner solid plate, a mounting connection, and a mounting bracket. The sides of both sets of inner solid plates are bolted with mounting brackets, and two sets of mounting brackets are installed between the two sets of mounting connection brackets.

[0009] Preferably, the bidirectional gate further includes a bottom support plate and an outer fixing plate. The bottom support plate is bolted between the two sets of inner fixing plates. The bottom end of the bottom support plate is provided with a connecting groove. The outer fixing plate is bolted to the edge of the inner fixing plate.

[0010] Preferably, the mobile lifting double gate platform includes a drive platform, with first fixed frames installed on both sides of the bottom of the drive platform, and a dual-axis drive frame provided above the drive platform. Both sides of the dual-axis drive frame are respectively engaged with rope winding rotating gear rings, and steel wire rope is wound inside the winding ring of the rope winding rotating gear ring.

[0011] Preferably, the reinforced push gate includes a gate body, side sliding plates, and positioning columns. Side sliding plates are provided on both sides of the gate body, and a number of positioning columns are provided at equal intervals on the top of the gate. The dam body and the reinforced push gate are slidably connected by a limiting sliding frame and the side sliding plates.

[0012] Preferably, the bottom end of the gate body of the reinforced push gate is provided with two sets of telescopic screws, and the bottom ends of the two sets of telescopic screws are provided with a spiral rotating sleeve. A drive motor for driving rotation is installed on the side of the spiral rotating sleeve, and a fixed base is provided below the drive motor. When the drive motor drives the spiral rotating sleeve to rotate, the telescopic screws located inside the spiral rotating sleeve are driven to move up and down.

[0013] Preferably, the bottom end of the wire rope is equipped with an installation joint, and the rotating toothed ring of the rope and the bidirectional gate are connected by the installation joint and the installation fixing frame to form a detachable structure.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] Compared with existing technologies, this adjustable-height mobile drainage and diversion platform for dam construction incorporates multiple structures, including an inner and outer solid plate and a bottom support plate, through a bidirectional gate. The outer solid plate enhances the overall strength of the gate, while the groove in the bottom support plate provides a positioning reference for the gate body of the reinforced push gate. When the drainage height needs to be adjusted during dam construction, the dual-shaft drive frame inside the drive platform rotates the gear ring through a meshing rope, simultaneously winding and unwinding the wire rope, driving the bidirectional gate to move vertically along the limiting sliding frame until its bottom groove aligns with the positioning column of the reinforced push gate. The variable drainage channel formed by the two is achieved through a drive structure composed of a telescopic screw and a spiral rotating sleeve. When the drive motor drives the spiral rotating sleeve to rotate, the telescopic screw pushes the gate body to change the initial height of the drainage outlet; simultaneously, the bidirectional gate moves synchronously under the traction of the wire rope, and the gap between the two forms a drainage section for release. Construction personnel can adjust the relative position of the two gates according to parameters such as the on-site water level and the distance to the construction area for release.

[0021] 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. Example 1

[0022] As attached Figures 1 to 4 The diagram shows a mobile drainage and diversion platform for dam construction with adjustable height, comprising a dam body 1 and a mobile lifting double gate platform 4. A dam observation top 2 is located above the dam body 1. Several drainage channels 3 are connected through the center of the dam body 1. Limiting sliding frames 5 are installed on both sides of each drainage channel 3. The mobile lifting double gate platform 4 is housed inside each limiting sliding frame 5. The mobile lifting double gate platform 4 includes a bidirectional gate 9 and a reinforced pushing gate 10. The reinforced pushing gate 10 is located below the bidirectional gate 9. During dam construction... During the process, the reinforced push gate 10 is used to block the discharge end of the water source. At this time, the mobile lifting double gate platform 4 drives the bidirectional gate 9 into the dam body 1 and moves it, so that the bidirectional gate 9 is connected to the reinforced push gate 10. The two move up and down, so that the height of the drainage can be discharged through the gap between the two. The water flow rate is adjusted by the space restricted by the two. By adjusting the drainage height, the drainage area is kept away from the construction area, thereby reducing the impact of drainage on the construction process.

[0023] In a preferred embodiment, the bidirectional gate 9 includes an inner solid plate 20, a mounting connecting frame 21, and a mounting fixing frame 2101. The sides of both sets of inner solid plates 20 are bolted to the mounting connecting frame 21, and two sets of mounting fixing frames 2101 are installed between the two sets of mounting connecting frames 21. The bidirectional gate 9 also includes a bottom support plate 22 and an outer solid plate 23. The bottom support plate 22 is bolted between the two sets of inner solid plates 20. The bottom end of the bottom support plate 22 is provided with a connecting groove. The outer solid plate 23 is bolted to the edge of the inner solid plate 20. The inner side of the inner solid plate 20 in the bidirectional gate 9 is provided with... The mounting bracket 21 has two sets of mounting brackets 21 that limit the spatial distance within the inner solid plate 20. The mounting fixing bracket 2101 set on the mounting bracket 21 is used to connect with the wire rope 8 on the drive platform 6 above, so as to drive the bidirectional gate 9. The outer solid plate 23 set on the outside of the inner solid plate 20 increases the overall strength of the bidirectional gate 9 structure. Then, the bottom support plate 22 inside the two sets of inner solid plates 20, while installing the inner solid plate 20, also limits the contact depth of the gate body 1001 of the reinforcing push gate 10.

[0024] In a preferred embodiment, the mobile lifting double gate platform 4 includes a drive platform 6. First fixed frames 7 are installed on both sides of the bottom of the drive platform 6. A dual-shaft drive frame 15 is installed above the drive platform 6. Rope winding gear rings 16 are respectively engaged on both sides of the dual-shaft drive frame 15. A steel wire rope 8 is wound inside the winding ring of the rope winding gear ring 16. The steel wire rope 8 is wound on the winding ring inside the rope winding gear ring 16. The drive platform 6 is rotatably connected to the rope winding gear ring 16 via a bracket. A motor inside the dual-shaft drive frame 15 drives a bidirectional gear shaft to rotate, causing the gear ends at both ends of the bidirectional gear shaft to mesh with the teeth on the rope winding gear ring 16. This causes the dual-shaft drive frame 15 to drive the rope winding gear ring 16 to rotate, and the steel wire rope 8 on the winding ring to be wound up. While the steel wire rope 8 moves up and down, its end engages with the mounting fixed frame 2101, thereby driving the bidirectional gate 9 to move up and down.

[0025] In a preferred embodiment, the reinforced push gate 10 includes a gate body 1001, side sliding plates 17, and positioning posts 18. Side sliding plates 17 are provided on both sides of the gate body 1001, and several sets of positioning posts 18 are equidistantly arranged at the top of the gate. The dam body 1 and the reinforced push gate 10 are slidably connected via a limiting sliding frame 5 and the side sliding plates 17. The top of the reinforced push gate 10 is inserted into a groove within the bottom support plate 22 and the inner solid plate 20 bracket, supporting the bidirectional gate 9. After the reinforced push gate 10 is connected to the bidirectional gate 9, it is pushed by the reinforced push gate. Driven by the gate 10, the bidirectional gate 9 is connected to the limiting sliding frame 5, thereby completing the connection of the bidirectional gate 9. The gate body 1001 of the reinforcing push gate 10 is moved by the telescopic screw 11, which rotates in the spiral rotating sleeve 12 and moves upward continuously, thereby driving the gate body 1001 of the reinforcing push gate 10 to move. At this time, when the bidirectional gate 9 and the push gate reach the designated position, the push gate moves downward and exposes the drainage end. As the separation distance between the two changes, the space between their drainage ends changes.

[0026] In a preferred embodiment, the bottom end of the gate body 1001 of the reinforced push gate 10 is provided with two sets of telescopic screws 11. The bottom ends of the two sets of telescopic screws 11 are provided with a spiral rotating sleeve 12. A drive motor 13 for driving rotation is installed on the side of the spiral rotating sleeve 12. A fixed base 14 is provided below the drive motor 13. When the drive motor 13 drives the spiral rotating sleeve 12 to rotate, the telescopic screws 11 located in the spiral rotating sleeve 12 are driven to move up and down. The spiral rotating sleeve 12 and the drive motor 13 are the drive structure for driving the telescopic screws 11 to move up and down.

[0027] In a preferred embodiment, the bottom end of the wire rope 8 is equipped with an installation joint 19, and the winding rotating toothed ring 16 and the bidirectional gate 9 are connected by the installation joint 19 and the installation fixing frame 2101 to form a detachable structure.

[0028] The working process of this utility model is as follows: First, the reinforced push gate 10 is used to block the discharge end of the water source. At this time, the mobile lifting double gate platform 4 drives the bidirectional gate 9 into the dam body 1 and moves it, so that the bidirectional gate 9 is connected to the reinforced push gate 10. At this time, the two move up and down, so that the drainage height can be discharged through the gap between them. The water flow rate is adjusted by the space restricted by the two. By adjusting the drainage height, the drainage area is kept away from the construction area, thereby reducing the impact of drainage on the construction process. Then, the inner reinforcement of the bidirectional gate 9... The mounting brackets 21 provided on the inner side of the plate 20 limit the spatial distance within the inner plate 20. The mounting brackets 2101 provided on the mounting brackets 21 are used to connect with the wire rope 8 on the drive platform 6 above, so as to drive the bidirectional gate 9. The outer plate 23 provided on the outer side of the inner plate 20 increases the overall strength of the bidirectional gate 9 structure. The bottom support plates 22 inside the two sets of inner plates 20 limit the contact depth of the gate body 1001 of the reinforcing push gate 10 while installing the inner plate 20.

[0029] The wire rope 8 is wound on the winding ring inside the rope rotating gear ring 16. The drive platform 6 is rotatably connected to the rope rotating gear ring 16 through the bracket, and the motor in the dual-shaft drive frame 15 drives the bidirectional gear shaft to rotate, so that the gear ends at both ends of the bidirectional gear shaft mesh with the teeth on the rope rotating gear ring 16. This causes the dual-shaft drive frame 15 to drive the rope rotating gear ring 16 to rotate, and the wire rope 8 on the winding ring is wound up. While the wire rope 8 moves up and down, the end of the wire rope 8 is engaged with the mounting bracket 2101, which drives the bidirectional gate 9 to move up and down.

[0030] The top of the reinforced push gate 10 is inserted into the groove in the bracket of the bottom support plate 22 and the inner solid plate 20, and supports the bidirectional gate 9. After the reinforced push gate 10 is connected to the bidirectional gate 9, the bidirectional gate 9 is driven by the reinforced push gate 10 to connect with the limiting sliding frame 5, thereby completing the connection of the bidirectional gate 9. The gate body 1001 of the reinforced push gate 10 is moved by the telescopic screw 11, which rotates in the spiral rotating sleeve 12 and moves upward, thereby driving the gate body 1001 of the reinforced push gate 10 to move. When the bidirectional gate 9 and the push gate reach the designated position, the push gate moves downward and exposes the drainage end. As the separation distance between the two changes, the space between their drainage ends changes. The above is the working principle of this mobile drainage and diversion platform for dam construction with adjustable height.
