[0002] Ancient building repair and protection devices refer to various auxiliary equipment and technical measures installed or used during the repair process of ancient buildings and after the repair is completed to keep the ancient buildings safe, stable and prevent further damage. These devices are usually designed to meet specific protection needs, such as lightning protection, fire protection, moisture protection, insect protection, structural reinforcement, etc. Among them, pillars are important supports for buildings. The pillars of ancient buildings will be damaged on the surface after long-term exposure to wind, sun and rain, and may also be eaten by insects. This requires the pillars of ancient buildings to be sprayed with paint to protect the supporting pillars of ancient buildings.

[0003] For example, the patent with announcement number CN220301836U discloses a uniform spraying device for surface repair and protection of ancient buildings, including a bottom plate, a paint box is installed on the top right side of the bottom plate, a water pump is installed on the top of the paint box, a support shell is installed on the top left side of the bottom plate, and a motor 1 is installed on the top of the support shell. The problem that the manual spraying efficiency of the staff is low, the labor intensity is high, it is inconvenient to spray at high places, and the need to spray around the column easily causes uneven spraying and unsightly is solved. The output end of the motor 2 drives the rotating rod and the gear to rotate, so that the installation frame and the bottom plate rotate around the column as the center, changing the spraying position, while ensuring the stability of the movement around the column, ensuring that the distance between the gathering plate and the surface of the column remains unchanged, and no manual spraying is required, reducing labor intensity and improving efficiency while ensuring uniform spraying.

[0004] However, the ancient building protection device in the above technology still has the following problems:

[0005] During surrounding spray painting, the protective paint sprayed from the nozzle can easily fly into the air, polluting the interior space of the ancient building. The paint protection workers may inhale some of the paint scattered in the air into their bodies, which is not conducive to protecting the health of the repair workers. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] See also Figure 1 - Figure 6A protective device for repairing ancient buildings comprises a base 1, a lifting rod 2 and a first annular paint spraying pipe 3 installed on the lifting rod 2, a plurality of first paint spraying heads 4 are installed in the first annular paint spraying pipe 3, a side of the first annular paint spraying pipe 3 close to the lifting rod 2 is fixedly connected and connected with a first connecting pipe head 5, a side of the first annular paint spraying pipe 3 is rotatably connected with a second annular paint spraying pipe 6, a side of the second annular paint spraying pipe 6 close to the first annular paint spraying pipe 3 is fixedly connected and connected with a plurality of second paint spraying heads 7, the first annular paint spraying pipe 3 and the second annular paint spraying pipe 6 are fixedly connected with an anti-scattering cover 8 on the sides close to the base 1, and the two anti-scattering covers 8 are matched, the second annular paint spraying pipe 6 is fixedly connected with a second connecting pipe head 9 on the sides away from the plurality of second paint spraying heads 7, the first annular paint spraying pipe 3 and the second annular paint spraying pipe 6 are connected with a limiting cover 10 on the sides away from the base 1, and the two limiting covers 10 are matched.

[0025] like Figure 1 - Figure 6 As shown, the structure of the protective device for repairing ancient buildings in the utility model is similar to that of the existing protective device for repairing ancient buildings, such as the uniform spraying device for surface repairing and protecting ancient buildings disclosed in the patent with publication number CN220301836U. The main improvement of the utility model is that it can reduce the pollution caused by the spray paint flying into the air and improve the quality of the spray paint working environment. Figures 1 to 5 As shown, when the protective device for repairing ancient buildings in the utility model is used, the first annular paint spraying tube 3 is moved close to the supporting column of the ancient building that needs to be repaired through the base 1 and the lifting rod 2, and then the second annular paint spraying tube 6 is flipped to the other side of the supporting column of the ancient building, so as to cooperate with the first annular paint spraying tube 3 to form a ring to wrap the supporting column of the ancient building, and then the paint spraying equipment is connected to the first annular paint spraying tube 3 and the second annular paint spraying tube 6 through the first connecting pipe head 5 and the second connecting pipe head 9 respectively. At this time, the supporting column of the ancient building can be repaired and painted, and the paint spraying equipment can be connected to the first annular paint spraying tube 3 and the second annular paint spraying tube 6 through the first connecting pipe head 5 and the second connecting pipe head 9. Paint repair is carried out on the surface of the supporting column of the ancient building through multiple first paint spray heads 4 and multiple second paint spray heads 7. During the paint repair operation, the sprayed paint powder is sprayed in a fan shape, and some of it will inevitably fly upward or downward. At this time, the paint powder scattered above is blocked by the two upper limiting covers 10, and the paint powder scattered below is blocked by the two lower anti-scattering covers 8, thereby preventing the paint powder from scattering into the air, avoiding pollution to the environment of the paint operation, avoiding inhalation by the paint workers, and reducing the physical harm to the paint workers.

[0026] like Figure 1 - Figure 5As shown, the two anti-scattering covers 8 are provided with cavities, and the adjacent sides of the two anti-scattering covers 8 are penetrated with a plurality of suction holes 801 connected with the cavities. The two anti-scattering covers 8 are fixedly connected and connected with a three-head suction pipe 11 at the same time on the side away from the suction hole 801. The other end of the three-head suction pipe 11 is fixedly connected and connected with an air pump 12. The air pump 12 is fixedly connected with one of the anti-scattering covers 8. When the paint powder falls, the air pump 12 simultaneously evacuates the two anti-scattering covers 8 through the three-head suction pipe 11, and extracts the paint powder falling within the range of the anti-scattering cover 8 through a plurality of suction holes 801 connected with the internal cavity of the anti-scattering cover 8, thereby preventing the powder from falling from the bottom of the anti-scattering cover 8 to the external environment. The suction force of the air pump 12 is less than the spray force sprayed by the paint spray head 4. The air pump 12 will not directly absorb the paint sprayed directly by the paint spray head 4, and will not affect the spraying effect.

[0027] like Figure 1 - Figure 3 As shown, one end of the first connecting pipe head 5 away from the first annular paint spray pipe 3 is fixedly connected and communicated with a three-head hose 13, and the other end of the three-head hose 13 is fixedly connected and communicated with the second connecting pipe head 9. The first connecting pipe head 5 is connected around the second connecting pipe head 9 through the three-head hose 13 and connected to the paint spraying equipment, so that one paint spraying equipment can simultaneously perform paint spraying operations of two annular paint spraying pipes, wherein the paint spraying equipment is an existing equipment.

[0028] like Figure 1 - Figure 5 As shown, the limiting cover 10 includes an annular cover 14 and a limiting plate 15. The annular cover 14 is fixedly connected to the adjacent first annular paint spray tube 3 or the second annular paint spray tube 6. The limiting plate 15 is fixedly connected to the side of the annular cover 14 away from the base 1. The limiting plate 15 is semicircular, and a limiting hole 101 is provided through the circular position of the limiting plate 15. When the first annular paint spray tube 3 and the second annular paint spray tube 6 are circled on the supporting column of the ancient building, the limiting hole 101 opened on the limiting plate 15 is against the surface of the supporting column of the ancient building, and another set of limiting plates 15 are clamped on the supporting column of the ancient building at the same time, so as to ensure that the first annular paint spray tube 3 and the second annular paint spray tube 6 are circled in the middle position of the supporting column of the ancient building as much as possible, so as to improve the uniformity of the repair paint spraying. At the same time, during the painting operation, the first annular paint spray tube 3 and the second fantasy paint spray tube 6 are moved from bottom to top to ensure that the limiting plate 15 will not scrape the paint on the pillar of the ancient building that has just been painted, and the limiting plate 15 can prevent the paint from being sprayed into the air from above, and the scattered paint will fall into the range of the anti-scattering cover 8 below and then be sucked.

[0029] like Figure 1 - Figure 5As shown, the limiting plate 15 is a rubber plate. The limiting plate 15 is set as a rubber plate to avoid damage to the surface of the ancient building support column when contacting with the surface of the ancient building support column.

[0030] like Figure 1 - Figure 6 As shown, the upper and lower ends of the first annular paint spraying tube 3 near the second annular paint spraying tube 6 are fixedly connected with connecting blocks 16, and a flipping block 17 is rotatably connected between the two connecting blocks 16 via a rotating shaft, and the end of the flipping block 17 away from the first annular paint spraying tube 3 is fixedly connected to the second annular paint spraying tube 6. By rotating and flipping the flipping block 17 between the two connecting blocks 16, the second annular paint spraying tube 6 is flipped on the first annular paint spraying tube 3, which is convenient for clamping the ancient building support column or opening from the ancient building support column.

[0031] like Figure 4 and Figure 5 As shown, the first annular paint spraying tube 3 and the second annular paint spraying tube 6 are fixedly connected with a magnetic block 18 at one end away from the flip block 17, and the two magnetic blocks 18 are magnetically attracted to each other. When the first annular paint spraying tube 3 and the second annular paint spraying tube 6 encircle the supporting column of the ancient building, the two magnetic blocks 18 are magnetically attracted to each other, so that the first annular paint spraying tube 3 and the second annular paint spraying tube 6 are connected and fixed, so as to prevent the annular ring formed between the first annular paint spraying tube 3 and the second annular paint spraying tube 6 from unfolding, thereby improving the connection stability of the repair spraying operation.

[0032] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
