Technical Field
[0001] This utility model relates to the technical field of rainwater erosion prevention devices, specifically a rainwater erosion prevention device for applying colored paintings. Background Technology
[0002] In traditional Chinese architecture, painted decorations are a form of decorative art, typically used to adorn the beams, columns, doors, and windows of buildings such as temples and palaces. Painted decorations usually contain various patterns and colors, and sometimes depict historical stories or religious scenes. During the construction of painted decorations, protecting the painted decorations is extremely important. In the rainy season, unfinished painted decorations are at risk of being damaged by rainwater. During rainy season construction, in order to prevent rainwater from splashing onto the painted decorations, it is required to have a dedicated person responsible for shielding them from wind and rain and for moving the scaffolding boards as needed.
[0003] Traditional protective measures typically include setting up fixed awnings or using materials such as plastic sheeting for temporary covering. When protecting murals during construction, fixed structures are generally used, which makes it difficult to adjust the rain-proof area of the rain-proof device and to adapt to the construction needs of murals of different sizes, thus reducing practicality. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a rainproof device for painted murals under construction. It offers advantages such as easily adjustable rain-blocking area to accommodate different sizes of murals. This solves the problem that methods commonly used to protect painted murals during construction, such as erecting fixed rainproof structures or covering them with large plastic sheets, are generally fixed structures that are inconvenient to adjust the rain-blocking area of the device, making it difficult to adapt to different sizes of murals and reducing its practicality.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for preventing rainwater erosion of painted surfaces, comprising two U-shaped frames, with support rods hinged to the front and rear sides of the lower surfaces of the two U-shaped frames via hinge seats, and support cylinders fixed to the outer sides of the four support rods via bolts, and an adjustment mechanism provided on the outer sides of the left and right U-shaped frames, with the opposite sides of the left and right U-shaped frames hinged together via hinge seats.
[0006] The adjustment mechanism includes two rectangular slide rods, two first threaded rods, two first handles, four connecting rods, and waterproof fabric. The two rectangular slide rods are slidably connected to the outside of the left and right U-shaped frames. The two first threaded rods are threadedly connected to the inside of the left and right U-shaped frames. The two first handles are fixed to opposite sides of the left and right first threaded rods. The opposite sides of the left and right first threaded rods are rotatably connected to opposite sides of the left and right rectangular slide rods via bearings. The bottom ends of the four connecting rods are hinged to the front and rear sides of the upper surface of the left and right rectangular slide rods via hinge seats. The opposite sides of the left and right connecting rods are hinged together via hinge seats. The waterproof fabric is disposed on the upper surface of the four connecting rods.
[0007] By adopting this technical solution, the rainproof device can be adjusted to meet the construction needs of different sized murals through the adjustment mechanism.
[0008] Furthermore, each of the four support cylinders has a base plate fixed to its bottom end, and threaded ground stakes are threadedly connected to the left and right sides of the upper surface of the base plate, with a handwheel at the top of each threaded ground stake.
[0009] By adopting this technical solution, threaded piles can be inserted into the foundation.
[0010] Furthermore, the rectangular slide bar moves linearly left and right on the outside of the U-shaped frame.
[0011] By adopting this technical solution, the rectangular slide bar and the U-shaped frame are matched with a gap, allowing for linear left and right movement.
[0012] Furthermore, an anti-slip sleeve is fixed to the outside of the handwheel, and the anti-slip sleeve is a rubber sleeve.
[0013] By adopting this technical solution, the stability of the handwheel during rotation is improved, and the anti-slip performance is enhanced.
[0014] Furthermore, the first threaded rod is located on the transverse central axis of the U-shaped frame.
[0015] By adopting this technical solution, the stability of the first threaded rod rotating inside the U-shaped frame can be improved.
[0016] Furthermore, the support rod is fitted with a gap between itself and the support cylinder, and the support rod moves linearly up and down on the outside of the support cylinder.
[0017] By adopting this technical solution, the support rod can be moved up and down inside the support cylinder by twisting the bolt, so as to adjust the height of the rainproof flushing device.
[0018] Furthermore, the base plate is located on the longitudinal central axis of the support cylinder.
[0019] By adopting this technical solution, the stability of the support cylinder fixed to the surface of the base plate is improved.
[0020] Furthermore, the right side of each of the support rods on the left is hinged with a reinforcing rod via a hinge seat, and the left side of each of the support rods on the right is provided with a connecting piece. The connecting piece is internally threaded with a second threaded rod, and the top end of the second threaded rod is fixed with a second handle. The right side of the upper surface of the reinforcing rod is provided with an insertion interface, and the bottom end of the second threaded rod is slidably inserted into the insertion interface. The upper surface of the reinforcing rod is in contact with the lower surface of the connecting piece.
[0021] By adopting this technical solution, the left and right support rods can be strengthened and fixed by the front and rear reinforcing rods, thereby improving the stability of the support.
[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0023] This waterproofing device features a U-shaped frame on each side, hinged together at opposite ends. The U-shaped frames can be folded. Four support rods are hinged to the front and rear sides of the lower surface of the U-shaped frames, also hinged together, allowing for folding. Simultaneously, four connecting rods are hinged to the front and rear sides of the upper surface of the rectangular sliding rods on each side, allowing for folding. Folding the connecting rods in opposite directions reduces the size of the waterproofing device. Rotating eight handwheels drives eight threaded ground stakes to rotate and move downwards within the four base plates, inserting them into the foundation, thus securing the waterproofing device. Fixed to the ground, the waterproof fabric installed on the outside of the four connecting rods provides rain protection. The waterproof fabric is foldable and made of lightweight and durable materials for easy carrying and operation. By twisting the bolts on opposite sides of the left and right support cylinders, the four support rods can be moved up and down inside the four support cylinders, so that the rainproof device can adapt to the needs of painting construction at different heights. By turning the first handle on the left and right sides, the rectangular sliding rods on the left and right sides can be moved left and right on the outside of the left and right U-shaped frame. Then, under the action of the connecting rods hinged by the hinge seat, the rainproof area of the waterproof fabric can be expanded left and right, so that the rainproof device can adapt to the needs of painting construction of different sizes.

The adjustment mechanisms 4 facilitate the adjustment of the rainproof area of the rainproof device to adapt to the needs of painting construction of different sizes. The opposite sides of the left and right U-shaped frames 1 are hinged together via hinge seats.
[0030] In this embodiment, the bottom ends of the four support cylinders 3 are all fixed with a base plate 5. The left and right sides of the upper surface of the base plate 5 are threaded with threaded ground stakes 6. The top of the threaded ground stakes 6 is provided with a handwheel 7. The outside of the handwheel 7 is fixed with an anti-slip sleeve, which is a rubber sleeve. The support rod 2 and the support cylinder 3 are fitted with a gap, and the support rod 2 moves linearly up and down on the outside of the support cylinder 3.
[0031] The base plate 5 is located on the longitudinal central axis of the support cylinder 3. The right side of the left support rod 2 is hinged with a reinforcing rod 8 through a hinge seat. The left side of the right support rod 2 is provided with a connecting piece 9. The internal thread of the connecting piece 9 is connected to a second threaded rod 10. The top of the second threaded rod 10 is fixed with a second handle 11. The right side of the upper surface of the reinforcing rod 8 is provided with an insertion interface 12. The bottom end of the second threaded rod 10 is slidably inserted into the insertion interface 12. The upper surface of the reinforcing rod 8 is in contact with the lower surface of the connecting piece 9.
[0032] It should be noted that after the rainproof flushing device is fixed on the ground, the front and rear reinforcing rods 8 can be flipped upwards so that the upper surface of the front and rear reinforcing rods 8 fits against the lower surface of the front and rear connecting pieces 9. Then, the second handles 11 on the front and rear sides can be rotated so that the bottom end of the second threaded rods 10 on the front and rear sides can be slidably inserted into the front and rear insertion interfaces 12. The front and rear reinforcing rods 8 can improve the stability of the left and right support rods 2.
[0033] Please see Figures 2 to 3 In order to facilitate the adjustment of the rain-proof area of the rain-proof water-washing device and adapt to the needs of painting construction of different sizes, the adjustment mechanism 4 in this embodiment includes two rectangular slide rods 41, two first threaded rods 42, two first handles 43, four connecting rods 44 and waterproof fabric 45. The two rectangular slide rods 41 are slidably connected to the outside of the left and right U-shaped frame 1, the two first threaded rods 42 are threadedly connected to the inside of the left and right U-shaped frame 1, and the two first handles 43 are fixed to the opposite side of the left and right first threaded rods 42.
[0034] In this embodiment, the opposite sides of the left and right first threaded rods 42 are rotatably connected to the opposite sides of the left and right rectangular slide rods 41 via bearings. The bottom ends of the four connecting rods 44 are hinged to the front and rear sides of the upper surface of the left and right rectangular slide rods 41 via hinge seats. The opposite sides of the left and right connecting rods 44 are hinged together via hinge seats. Waterproof fabric 45 is disposed on the upper surface of the four connecting rods 44. The waterproof fabric can be folded and retracted.
[0035] In this embodiment, the left and right U-shaped frames 1 are hinged to each other on opposite sides via hinge seats, allowing the left and right U-shaped frames 1 to be folded. The four support rods 2 are hinged to the front and rear sides of the lower surface of the left and right U-shaped frames 1 via hinge seats, allowing the four support rods 2 to be folded. At the same time, the four connecting rods 44 are hinged to the front and rear sides of the upper surface of the left and right rectangular slide rods 41 via hinge seats, allowing the four connecting rods 44 to be folded. The folding of the connecting rods 44 on the left and right sides in opposite directions reduces the size of the rainproof water scouring device. By rotating the eight handwheels 7, the eight threaded ground stakes 6 can be rotated inside the four base plates 5 and moved downwards and inserted into the foundation, thus fixing the rainproof water scouring device to the ground. The waterproof fabric 45 set on the outside of the four connecting rods 44 can provide rain protection.
[0036] In this embodiment, the rectangular slide bar 41 moves linearly left and right on the outside of the U-shaped frame 1, and the first threaded rod 42 is located on the transverse central axis of the U-shaped frame 1.
[0037] It should be noted that the waterproof fabric 45 can be folded and is made of lightweight and durable materials for easy carrying and operation.

By turning the first handle 43 on the left and right sides, the first threaded rods 42 on the left and right sides can be driven to rotate inside the left and right U-shaped frames 1 respectively, and then the rectangular sliding rods 41 on the left and right sides can be driven to move left and right on the outside of the left and right U-shaped frames 1. Then, under the action of the connecting rod 44 hinged by the hinge seat, the rainproof area of the waterproof fabric 45 can be unfolded left and right, so that the rainproof water rinsing device can adapt to the painting construction needs of different sizes.
[0038] The working principle of the above embodiments is as follows:
[0039] The left and right U-shaped frames 1 are hinged to each other on opposite sides via hinge seats, allowing the left and right U-shaped frames 1 to be folded. Four support rods 2 are hinged to the front and rear sides of the lower surface of the left and right U-shaped frames 1 via hinge seats, allowing the four support rods 2 to be folded. Simultaneously, four connecting rods 44 are hinged to the front and rear sides of the upper surface of the left and right rectangular sliding rods 41 via hinge seats, allowing the four connecting rods 44 to be folded. Folding the connecting rods 44 in opposite directions on the left and right sides reduces the size of the rainproof scouring device. Rotating the eight handwheels 7 drives the eight threaded ground stakes 6 to rotate inside the four base plates 5 and move downwards, inserting them into the foundation, thus fixing the rainproof scouring device to the ground. Waterproof fabric is installed on the outside of the four connecting rods 44. 45 can provide rain protection. The waterproof fabric 45 can be folded and is made of lightweight and durable materials for easy carrying and operation. By twisting the bolts on opposite sides of the left and right support cylinders 3, the four support rods 2 can be moved up and down inside the four support cylinders 3 so that the rainproof water rinsing device can adapt to the painting construction needs of different heights. By turning the first handle 43 on the left and right sides, the first threaded rods 42 on the left and right sides can be driven to rotate inside the left and right U-shaped frames 1 respectively. Then, the rectangular sliding rods 41 on the left and right sides can be driven to move left and right on the outside of the left and right U-shaped frames 1. Then, under the action of the connecting rod 44 hinged by the hinge seat, the rainproof area of the waterproof fabric 45 can be unfolded left and right so that the rainproof water rinsing device can adapt to the painting construction needs of different sizes.
