[0028] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0029] Before describing the various embodiments of this application in detail, the technical concept of this application is first briefly described: Currently, when spraying coatings on rectangular spillways, traditional coating spraying methods are often inefficient and produce poor coating uniformity, making it difficult to meet the repair needs of large rectangular spillways. Therefore, the coating spraying device for the surface of rectangular spillways provided in this application mounts a paint supply mechanism on a movable frame, which is driven by a drive mechanism to move, allowing the spraying mechanism to spray different locations on the rectangular spillway. The spraying process is precise, efficient, and uniform. The specific principle of the coating spraying device for the surface of rectangular spillways of this application will be described below with reference to more embodiments.

[0030] Specifically, such as Figure 1 and Figure 2 As shown, the coating spraying device for the surface of a rectangular spillway in this embodiment includes a movable frame 10, a drive mechanism 20, a paint supply mechanism 30, and a spraying mechanism 40. The movable frame 10 is used to move along the side wall of the spillway 100. The drive mechanism 20 is connected to the movable frame 10 and is used to drive the movable frame 10 to move. The paint supply mechanism 30 is installed on the movable frame 10. The spraying mechanism 20 is connected to the paint supply mechanism 30 and is used to supply paint to the spraying mechanism 40. The spraying mechanism 40 is used to spray paint onto the side wall of the spillway.

[0031] In one or more embodiments, the mobile frame 10 includes a base plate 11 and rollers 12. The rollers 12 are mounted on the bottom of the base plate 11, and the paint supply mechanism 30 is mounted on the top of the base plate 11. The mobile frame 10 serves as a support platform and a moving platform, driving the paint supply mechanism 30 to move as a whole.

[0032] In one or more embodiments, the drive mechanism 20 includes a drive motor 21, a pulley block 22, and a rope 23. The drive motor 21 and pulley block 22 are mounted above the spillway. The two ends of the rope 23 are connected to the drive motor 21 and the movable frame 10, and the rope 23 passes around the pulley block 22. The drive motor 21 and pulley block 22 are detachably mounted to the spillway, allowing the position of the drive motor 21 and pulley block 22 to be moved along the length of the spillway to drive the paint supply mechanism 30 to spray paint at different positions along the side wall of the spillway. The drive motor above the spillway can precisely control the rotational speed of the pulley block, with the speed error set within a certain range, thereby controlling the moving speed of the movable frame and moving the paint supply mechanism 30 to the starting position at one end of the rectangular spillway as the spraying starting point, ensuring the uniformity of the coating spray.

[0033] In one or more embodiments, the paint supply mechanism 30 includes a paint storage tank 31, a stirring device 32, and an air compressor 33. The paint storage tank 31 is mounted on the movable frame 10, and the spraying mechanism 40 is connected to the paint storage tank 31. The stirring device 32 is installed inside the paint storage tank 31, and the air compressor 33 is connected to the paint storage tank 31. The air compressor 33 is used to adjust the internal pressure of the paint storage tank 31 to drive the paint into the spraying mechanism 40. Exemplarily, the stirring device 32 includes stirring blades 311, a stirring shaft 312, a stirring roller 313, a horizontal rotating support 314, and a stirring motor 315. The paint storage tank 31 is designed to be sealed to prevent paint evaporation from causing environmental pollution.

[0034] Furthermore, such as Figure 3 As shown, the air compressor 33 has a slide rail 331 on its side, and a pull rod 332 that can slide along the slide rail 331. The pull rod 332 allows for easy extension and retraction, reducing the footprint, facilitating operation, saving costs, and ensuring high safety. The slide rail 331 and pull rod 332 are located in the ventilation path. By adjusting the position of the pull rod 332, the size of the ventilation opening is adjusted, thereby adjusting the internal pressure of the paint storage tank 31.

[0035] In one or more embodiments, the spraying mechanism 40 includes a feed pipe 41 and a coating brush 42, with both ends of the feed pipe 41 connected to a paint storage tank 31 and the coating brush 42. The angle of the coating brush 42 of the spraying mechanism can be adjusted in both the horizontal and vertical directions, with an adjustment range of 0 to 90 degrees, to adapt to rectangular spillways of different widths and slopes. The feed pipe 41 is made of corrosion-resistant material to ensure that it will not leak due to corrosion during long-term use, thereby ensuring the safety and environmental friendliness of the construction.

[0036] In one or more embodiments, the coating spraying device further includes a recovery mechanism 50, which includes a recovery pipe 51 and a recovery tank 52. The two ends of the recovery pipe 51 are connected to the recovery tank 52 and the paint storage box 31. The recovery tank 52 is used to receive excess paint during the spraying process of the spraying mechanism 40. Further, as... Figure 4 As shown, a recovery pump is installed inside the recovery pipe, and an absorber 53 is installed inside the recovery tank 52. During the coating spraying process, excess material is allowed to flow along the overflow channel surface into the recovery device under gravity. For example, when excess paint is sprayed from the nozzle, it flows down the overflow channel slope and is collected in the recovery tank. Simultaneously, a filter element 54 is installed inside the recovery mechanism 50 to filter the collected material, separating impurities and reusable materials. The filtered material is then stored in a specific container within the recovery mechanism 50 for subsequent processing or reuse.

[0037] The working process of the coating spraying device for the surface of a rectangular spillway in this embodiment is as follows:

[0038] First, the installation and commissioning of the device are carried out. A supporting structure is erected above the rectangular spillway, pulley blocks are installed, and the mobile frame is connected to the pulley blocks. The drive motor is installed and the power supply and control lines are connected, and its speed control function is tested. The paint supply mechanism is installed on the mobile frame, the paint supply system is connected, and the pipe connections and nozzle status are checked.

[0039] Next, prepare the paint. Mix the paint according to the repair coating formula and inject it into the paint supply system's hopper. Adjust the paint supply pressure to a suitable value using the pressure regulating device. Then, set the spraying starting position. By operating the motor drive system, move the mobile frame to one end of the spillway, such as the far left or far right, as the starting point.

[0040] Next, the horizontal spraying begins. The motor is started, driving the pulley system at the set speed, causing the moving frame to move laterally along the spillway at a uniform speed. Simultaneously, the coating brush of the spraying mechanism is activated, and the paint is sprayed evenly onto the surface of the spillway under pressure. During the spraying process, the angle and position of the coating brush are adjusted as needed according to the width of the spillway and the coverage area of ​​the nozzles to ensure uniform coating coverage.

[0041] After completing one horizontal row of spraying, the vertical row is switched. The drive motor controls the moving frame to move longitudinally to the starting position of the next row, ready for the next round of horizontal spraying. This process of horizontal spraying and vertical switching is repeated until the entire rectangular spillway surface is coated.

[0042] Finally, wait for the coating to cure. Based on the curing characteristics of the coating, maintain a stable environment in the spillway after spraying to allow the coating to cure naturally. Simultaneously, clean the spraying equipment, including cleaning the nozzles, material tanks, pipes, and other components. Inspect the wear and tear of each component and perform necessary maintenance and upkeep for future use.

[0043] The specific embodiments of this application have been described in detail above. Although some embodiments have been shown and described, those skilled in the art should understand that modifications and improvements can be made to these embodiments without departing from the principles and spirit of this application as defined by the claims and their equivalents, and such modifications and improvements should also be within the protection scope of this application.
