Description

Technical Field

[0001] This utility model belongs to the field of underwater water-stopping repair construction technology for panel dams, and particularly relates to a continuous scraping and coating device for underwater surface water-stopping and sealing of panel dams. Background Technology

[0002] As a common type of dam in water conservancy projects, the reliability of the surface water-stopping structure of panel dams is directly related to the seepage prevention performance and long-term operational safety of the project. The sealing treatment of the underwater surface water-stopping cover is one of the key procedures to ensure the water-stopping effect.

[0003] During the operation of panel dams, the sealing of underwater surface waterproofing covers typically requires the application of sealing agent to the waterproofing edges in an underwater environment. Traditional methods rely primarily on manual operation by divers, who carry the sealing agent underwater and apply it manually. However, this manual method has significant drawbacks: firstly, the complex underwater environment, including currents and low visibility, severely affects the diver's precision, leading to uneven application of the sealing agent and compromising the sealing effect, thus impacting the sealing and durability of the waterproofing structure; secondly, manual operation is inefficient, requiring divers to spend considerable time repeatedly applying and adjusting the sealant, increasing labor intensity and extending the construction period. Furthermore, prolonged underwater work increases the safety risks for divers.

[0004] This utility model designs a continuous scraping and coating device for underwater surface sealing of panel dams to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A continuous scraping device for underwater surface sealing of panel dams includes a horizontal truss and a casting pipe. The casting pipe is installed on the horizontal truss via a pin connection assembly. The pin connection assembly includes a pin hole, a support bracket, and a fixing pin. The pin hole is located on the horizontal truss, the support bracket is fixed on the casting pipe, and the fixing pin is installed on the support bracket and the pin hole. A casting funnel is installed at the top of the casting pipe, a valve is installed at the bottom of the casting pipe, and a scraper is installed on the casting pipe located behind the valve. Support frames are installed at the four corners of the horizontal truss.

[0006] As a preferred option, there are two casting pipes, which are distributed on the horizontal truss.

[0007] As a preferred embodiment, a pin connection assembly includes at least two pin holes, which are distributed horizontally on the horizontal truss. The support bracket is provided with at least two through holes that are adapted to the shape of the pin holes, and at least one through hole is distributed on each of the left and right sides of the casting pipe.

[0008] As a preferred embodiment, a pin connection assembly includes at least two support brackets distributed vertically on the casting pipe.

[0009] As a preferred option, the lower end of the scraper is inclined away from the pouring pipe.

[0010] As a preferred option, the bottom of the support frame is equipped with rollers.

[0011] As a preferred embodiment, the front support frame is set perpendicular to the horizontal truss, and the rear support frame is set inclined to the rear, with the front and rear support frames and the horizontal truss forming an approximately triangular position.

[0012] Compared with existing technologies, the advantages of this utility model are: 1. The horizontal truss and pouring pipe structure designed in this utility model allows the sealing agent to be precisely poured into the target position through the pouring pipe and automatically applied by a scraper, enabling continuous underwater construction and significantly improving work efficiency. Divers only need to pour the sealing agent into the pouring pipe, reducing underwater operation time and labor intensity, while improving construction accuracy and avoiding quality fluctuations caused by manual application.

[0013] 2. The pin connection assembly designed in this utility model, by setting multiple pin holes, realizes the horizontal position adjustment of the casting pipe on the horizontal truss, adapting to water-stop structures of different widths. By setting multiple support brackets, it realizes the height adjustment of the casting pipe on the horizontal truss, meeting the vertical height requirements of different water-stop structures and improving the versatility of this device.

[0014] 3. The angle between the scraper and the pouring pipe of this utility model can be adjusted according to the actual slope and construction requirements to ensure uniform application of the sealing agent and adapt to the construction requirements of different dam surface inclinations. The scraper design can effectively avoid uneven application caused by slope changes, improving the sealing performance and durability of the water-stopping seal.

[0015] 4. This utility model adjusts the connection angle between each support frame and the horizontal truss to form an approximately triangular support state between the support frames on the front and rear sides and the horizontal truss, thereby enhancing the overall rigidity, ensuring the stability of the device during water flow impact or movement, and reducing the risk of displacement. The rollers facilitate underwater movement and positioning, improving construction flexibility. Attached Figure Description

[0020] A continuous scraping and coating device for underwater surface sealing of panel dams, such as Figure 1 and Figure 2 As shown, the system includes a horizontal truss 1 and a pouring pipe 2. The pouring pipe 2 is installed on the horizontal truss 1 via a pin connection assembly. The pin connection assembly includes a pin hole 3, a support bracket 4, and a fixing pin 5. The pin hole 3 is located on the horizontal truss 1, the support bracket 4 is fixed to the pouring pipe 2, and the fixing pin 5 is installed on the support bracket 4 and the pin hole 3. A pouring funnel 7 is installed at the top of the pouring pipe 2, and a valve 6 is installed at the bottom of the pouring pipe 2. A scraper 8 is installed on the pouring pipe 2, located behind the valve 6. Support frames 9 are installed at each of the four corners of the horizontal truss 1. The lower end of the scraper 8 is inclined away from the pouring pipe 2.

[0021] The sealing agent is precisely injected into the target location through the pouring pipe 2 and automatically applied by the scraper 8, enabling continuous underwater construction and significantly improving work efficiency. Divers only need to pour the sealing agent into the pouring pipe 2, reducing underwater operation time and labor intensity, while improving construction accuracy and avoiding quality fluctuations caused by manual application.

[0022] Valve 6 adopts the valve 6 device disclosed in the prior art. Valve 6 is used to control the opening and closing state of the bottom opening of the casting pipe 2. When valve 6 is opened, the object in the casting pipe 2 can be discharged from the bottom of the casting pipe 2. When valve 6 is closed, the bottom of the casting pipe 2 is in a closed state.

[0023] The installation angle of the scraper 8 on the pouring pipe 2 can be adjusted. It can be connected by a conventional rotating method and the angle of the scraper 8 can be fixed by a structure such as threaded fasteners.

[0024] There are two casting pipes 2, which are distributed on the horizontal truss 1. Each pin connection assembly includes at least two pin holes 3, which are distributed horizontally on the horizontal truss 1. Each support bracket 4 has at least two through holes 10 that match the shape of the pin holes 3. At least one through hole 10 is distributed on each of the left and right sides of each casting pipe 2. Each pin connection assembly includes at least two support brackets 4, which are distributed vertically on the casting pipe 2.

[0025] By setting multiple pin holes 3, the horizontal position of the casting pipe 2 on the horizontal truss 1 can be adjusted to accommodate water-stop structures 12 of different widths. By setting multiple support brackets 4, the height of the casting pipe 2 on the horizontal truss 1 can be adjusted to meet the vertical height requirements of different water-stop structures 12, thus improving the versatility of the device. Rollers 11 are installed at the bottom of the support frame 9. The front support frame 9 is set perpendicular to the horizontal truss 1, and the rear support frame 9 is set inclined to the rear. The front and rear support frames 9 are in an approximately triangular position with the horizontal truss 1.

[0026] The triangular support between the support frame 9 and the horizontal truss 1 enhances the overall rigidity, ensuring the stability of the device during water flow impact or movement, and reducing the risk of displacement. The rollers 11 facilitate underwater movement and positioning, improving construction flexibility.

[0027] Work steps: (A) Installation and positioning of the device ① Assemble the horizontal truss 1 and the support frame 9 into a triangular stable structure. Connect the horizontal truss 1 to the water surface traction device 13 through the traction rope 14. Check the connection status of the roller 11 and the traction rope 14 to ensure the flexibility of movement and the stability of the structure.

[0028] ②The entire device is hoisted to the underwater construction area via a surface work platform. Divers assist in adjusting the position of roller 11 to initially position the device along the side of the waterstop structure 12.

[0029] (B) Multi-dimensional adjustment system operation ① Vertical and horizontal adjustment: Select an appropriate support bracket 4 according to the height requirement of the water-stop structure 12, and select an appropriate pin hole 3 according to the width requirement between the two water-stop structures 12. Fix the support bracket 4 to the pin hole 3 by fixing the pin 5, and adjust the position of the pouring pipe 2 on the horizontal truss 1.

[0030] ② According to the slope of the dam surface, manually adjust the angle between the scraper 8 and the pouring pipe 2. The angle adjustment range is 15°-45° to ensure that the angle between the scraper 8 and the dam surface is adapted.

[0031] (C) Continuous application of edge sealant ① The diver pours the premixed sealing agent into two casting funnels 7 and controls the underwater movement speed of the horizontal truss 1 through the surface traction device 13. The movement speed is 1.5-2m / min.

[0032] ② Open the valve 6 at the bottom of the pouring pipe 2. The sealing agent is precisely poured into the surface of the water-stop structure 12 through the hollow pouring pipe 2, and is automatically scraped by the scraper 8 at the same time.

[0033] ③ Real-time monitoring of coating thickness can be achieved by adjusting the speed of the water surface traction device 13 or by finely adjusting the scraper 8 within a ±5° angle to correct coating uniformity and ensure that the thickness error is <3mm.

[0034] (D) Continuous operation and location migration ① After a single section of construction is completed, close valve 6 on the pouring pipe 2 and use traction rope 14 to pull the entire device to the next construction section.

[0035] ② Repeat steps (B)-(C) to make local fine adjustments to adapt to changes in the size and slope of the new construction section.

[0036] (E) Construction completion and recycling ① After all the edge sealing work is completed, close all valves 6, use the traction rope 14 to lift the whole device to the water surface, remove the pouring pipe 2 from the horizontal truss 1, rinse the pouring pipe 2, pouring funnel 7 and scraper 8 for residual edge sealing agent, and complete the equipment maintenance.
