Description

Technical Field

[0001] This invention relates to the field of cultural relic protection and restoration equipment technology, specifically a flexible mineralization repair spraying device for weathered and peeling layers on the surface of grotto statues. Background Technology

[0002] Grotto statues, exposed to the natural environment for extended periods, suffer from multiple effects including rainwater erosion, temperature and humidity cycles, salt crystallization, and wind and sand abrasion. Consequently, the rock surface commonly exhibits weathering damage such as powdering, flaking, and peeling. Flexible mineralization restoration agents are needed to penetrate and reinforce the weathered layer, providing thin-layer sealing treatment. However, flexible mineralization restoration solutions are mostly inorganic mineral precursor suspensions, which are prone to solid-phase precipitation and stratification after settling. Direct spraying can result in uneven agent concentration and significant differences in reinforcement effects, severely impacting the quality of cultural relic restoration.

[0003] The existing grotto restoration spraying equipment has obvious defects:

[0004] 1. Traditional spraying equipment has a fixed nozzle height. For the statue facades of grottoes with varying heights and uneven surfaces, it is necessary to manually move the whole machine repeatedly or hold the nozzle by hand, which is labor-intensive and makes it difficult to control the thickness of the spray.

[0005] Second, the mixing mechanism and the nozzle lifting and adjustment are independent of each other, requiring two independent power systems to control the mixing and lifting respectively. The equipment structure is bulky, and it is inconvenient to transport in the narrow passage of the grotto. The manufacturing cost and energy consumption are relatively high.

[0006] To address these issues, the present invention provides a flexible mineralization repair spraying device for weathered and peeling layers on the surface of grotto statues. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a flexible mineralization repair spraying device for weathered and peeling layers on the surface of grotto statues, solving the problems mentioned in the background section.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a flexible mineralization repair spraying device for the weathered and peeling layer on the surface of a grotto statue, comprising a movable base. A storage tank for uniformly holding and storing a special spraying liquid for flexible mineralization repair of grotto statues is fixedly mounted on one side of the top of the movable base. An installation box is fixedly mounted on the other side of the top of the movable base. The installation box is equipped with a spraying mechanism capable of outputting the mineralization repair spraying liquid and completing the spraying operation on the weathered surface of the grotto statue. The fluid delivery pipeline inside the spraying mechanism is sealed and connected to the storage cavity inside the storage box. The installation box is equipped with a rotary adjustment mechanism for adjusting the spraying height. The storage box is equipped with a stirring rod for stirring the spraying liquid to prevent sedimentation. During the operation of the rotary adjustment mechanism to drive the spraying mechanism to raise and lower and adjust the spraying height, the stirring rod is simultaneously driven to move back and forth vertically inside the storage box, realizing integrated linkage between spraying height adjustment and agent stirring.

[0009] Preferably, the spraying mechanism includes a pump body fixedly installed on the top of the storage tank. The liquid inlet end of the pump body is sealed and fixedly connected to an inlet pipe extending downward into the liquid in the storage tank for drawing mineralization repair spraying liquid. The end of the inlet pipe away from the pump body is connected to the interior of the storage tank. The outlet end of the pump body is sealed and fixedly connected to an outlet pipe for conveying pressurized repair liquid outward. The end of the outlet pipe away from the pump body is connected and fixedly connected to a nozzle that can atomize and spray flexible mineralization repair agent, suitable for thin-layer repair of curved surfaces.

[0010] Preferably, the top of the mounting box is vertically fixed with multiple vertical support rods for support and positioning. A support plate is horizontally fixed between the top ends of the multiple support rods. A support frame that can be freely raised and lowered vertically along the plate is mounted vertically through and slidingly on the support plate. A water supply pipe is fixedly mounted through the support frame. The water outlet end of the water supply pipe away from the pump body is sealed and fixedly connected to the bottom end of the water supply pipe. The spray head is sealed and fixedly mounted at the end of the water supply pipe away from the water outlet end, and rises and falls synchronously with the support frame to complete the spraying height adjustment.

[0011] Preferably, the water outlet pipe is made of a corrugated flexible hose that can be freely bent and stretched to compensate for displacement differences as it rises and falls with the support frame, thus avoiding pipe damage and leakage during the lifting process; the water supply pipe is made of rigid, non-deformable hard water pipe, which keeps the pipe straight during the lifting process and ensures that the spraying direction of the nozzle is stable and does not deviate.

[0012] Preferably, the rotation adjustment mechanism includes a guide rod fixedly disposed vertically downward at the bottom of the support plate, a guide disc slidably sleeved on the outer surface of the guide rod, the bottom of the support frame being fixedly connected to the top surface of the guide disc, and the guide disc directly driving the entire support frame to rise and fall synchronously when sliding vertically along the guide rod.

[0013] Preferably, a drive disk is rotatably embedded inside the top wall of the mounting box. Adjustment blocks for lifting the guide disk are symmetrically fixed on the upper surface of the drive disk. The adjustment blocks are arc-shaped block structures, and the top surface of the adjustment blocks is an inclined surface. Mounting frames are symmetrically fixed downward at the bottom of the guide disk. Drive wheels that can roll along the inclined surface are embedded and rotatably mounted inside the bottom end of each mounting frame. The drive wheels are in close rolling contact with the inclined surface of the adjustment blocks. The overall lifting and lowering of the guide disk is achieved by changing the support height of the drive wheels through the rotation of the drive disk.

[0014] Preferably, a drive column is fixedly installed at the bottom of the drive disk, and a drive gear is fixedly installed at the bottom end of the drive column. A drive screw is rotatably installed inside the mounting box, and a drive motor is fixedly installed inside the mounting box. The output shaft of the drive motor is fixedly connected to the end of the drive screw through a coupling. A positioning rod is also fixedly installed inside the mounting box. A drive block is threadedly connected to the outer surface of the drive screw. The positioning rod passes through the drive block and is slidably connected to its inner surface. A drive gear plate is fixedly installed on one side of the drive block. The drive gear plate meshes with the drive gear. The motor drives the screw to translate the gear plate, thereby driving the gear and the drive disk to rotate synchronously.

[0015] Preferably, a connecting frame is slidably disposed through the support plate, and a connecting shaft is rotatably disposed at the end of the connecting frame away from the support plate. The bottom end of the connecting shaft extends into the interior of the storage tank, and the outer surface of the stirring rod is fixedly disposed on the connecting shaft, rotating synchronously with the connecting shaft to complete the stirring and mixing of the repair fluid.

[0016] Preferably, a guide sleeve is vertically and sealed and fixedly installed at the center of the inner top wall of the storage box. The inner surface of the guide sleeve is provided with a spiral guide groove that limits the lifting and rotating trajectory of the connecting shaft. A limiting protrusion is fixedly provided on the outer surface of the connecting shaft. The outer end of the limiting protrusion is slidably embedded in the spiral guide groove. When the connecting shaft moves vertically up and down with the connecting frame, the vertical linear motion is converted into the rotational motion of the connecting shaft itself by the cooperation of the protrusion and the spiral guide groove, which synchronously drives the stirring rod to rotate and stir the sprayed liquid.

[0017] Beneficial effects

[0018] This invention provides a flexible mineralization repair spraying device for the weathered and peeling layer on the surface of grotto statues. Compared with the prior art, it has the following advantages:

[0019] (1) The flexible mineralization repair spraying equipment for the weathered and peeled layer on the surface of the grotto statues achieves stepless adjustment of the nozzle height and reciprocating motion of the stirring component in the storage tank through a set of rotary adjustment mechanism. The independent stirring power unit is eliminated, which greatly simplifies the mechanical structure of the whole machine, reduces the overall size of the equipment, and is suitable for transportation operations in narrow passages of grottoes. At the same time, it reduces the equipment manufacturing cost and operating energy consumption. During the operation, the stirring rod continuously stirs the repair slurry throughout the entire area as the nozzle rises and falls, which can disperse the mineralization agent precipitate particles in real time and ensure that the concentration of the spraying solution is uniform throughout the process.

[0020] (2) The flexible mineralization repair spraying equipment for the weathered and peeling layer on the surface of the grotto statues achieves smooth lifting and lowering of the nozzle through inclined rolling jacking and screw tooth plate meshing transmission. It is equipped with a segmented fluid delivery structure of corrugated hose and rigid water supply pipe. During the lifting process, the pipeline can adaptively compensate for the height displacement difference, prevent pipeline pulling damage and leakage, and the rigid pipeline ensures the stability of the nozzle spray angle. At the same time, relying on the spiral guide groove, the vertical reciprocating motion of the stirring rod is converted into rotational motion, and the stirring range covers the entire liquid height of the storage tank. There is no need for manual stopping of stirring, which greatly reduces the labor intensity of cultural relic restoration personnel. It can continuously complete thin-layer uniform mineralization spraying on the weathered and peeling layer of the grotto statues with uneven heights and complex curved surfaces, improving the efficiency and quality of grotto disease repair construction.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-8 This invention provides a technical solution: a flexible mineralization repair spraying device for the weathered and peeling layer on the surface of a grotto statue, comprising a movable base 1, a storage tank 2 for uniformly holding and storing a special spraying liquid for flexible mineralization repair of grottoes fixedly mounted on one side of the top of the movable base 1, and an installation box 3 fixedly mounted on the other side of the top of the movable base 1. The installation box 3 is equipped with a spraying mechanism 4 capable of outputting the mineralization repair spraying liquid and completing the spraying operation on the weathered surface of the grotto statue, and the fluid delivery pipeline inside the spraying mechanism 4 is sealed and connected to the storage cavity inside the storage box 2. The installation box 3 is equipped with a rotary adjustment mechanism 5 for adjusting the spraying height, and the storage box 2 is equipped with a stirring rod 6 for stirring the spraying liquid to prevent sedimentation. In the process of driving the spraying mechanism 4 to raise and lower to adjust the spraying height, the rotary adjustment mechanism 5 simultaneously drives the stirring rod 6 to move synchronously back and forth in the vertical direction inside the storage box 2.

[0032] As explained, the mobile base 1 serves as the support base for the entire machine and can be equipped with universal casters to allow the machine to be moved flexibly on the grotto floor. The left and right sections of the mobile base 1 respectively support the storage box 2 and the installation box 3, allowing for the separate arrangement of the liquid storage unit and the transmission adjustment unit, thus preventing leakage of the liquid and contamination of the internal transmission parts. The storage box 2 adopts a sealed box structure to store the inorganic mineralization repair suspension in a sealed manner, preventing the liquid from evaporating and external dust from falling in and causing the agent to become ineffective. The installation box 3 is a closed shell that encloses all lifting and linkage transmission components, isolating them from the grotto's moisture and dust, reducing the probability of corrosion and wear of the transmission components, and extending the service life of the equipment.

[0033] The spraying mechanism 4 includes a pump body 401 fixedly installed on the top of the storage tank 2. The liquid inlet end of the pump body 401 is sealed and fixedly connected to an inlet pipe 402 that extends downward into the liquid in the storage tank 2 for extracting mineralization repair spraying liquid. The end of the inlet pipe 402 away from the pump body 401 is connected to the interior of the storage tank 2. The outlet end of the pump body 401 is sealed and fixedly connected to an outlet pipe 403 that delivers pressurized repair liquid outward. The end of the outlet pipe 403 away from the pump body 401 is connected and fixedly connected to a nozzle 404 that can atomize and spray flexible mineralization repair agent and is suitable for thin-layer repair of curved surfaces.

[0034] After the pump body 401 is started, it forms a negative pressure suction force, which draws the mineralized repair liquid that is stirred evenly inside the storage tank 2 through the water inlet pipe 402 that is completely submerged at the bottom of the liquid. After the impeller inside the pump body 401 pressurizes the liquid, it is delivered to the water outlet pipe 403. The liquid then reaches the top nozzle 404 through the rigid water delivery pipe 405. The atomizing channel inside the nozzle 404 disperses the high-pressure liquid into uniform fine droplets, which are then thinly and evenly covered on the surface of the weathered and peeling layer of the grotto statue, completing the penetration and reinforcement spraying.

[0035] The top of the mounting box 3 is vertically fixed with multiple vertical support rods 7 for support and positioning. The top ends of the multiple support rods 7 are horizontally fixed with a support plate 8. The support plate 8 is vertically and slidably fitted with a support frame 9 that can be freely raised and lowered vertically along the plate surface. A water supply pipe 405 is fixedly installed through the support frame 9. The water outlet end of the water outlet pipe 403 away from the pump body 401 is sealed and fixedly connected to the bottom end of the water supply pipe 405. The nozzle 404 is sealed and fixedly installed at the end of the water supply pipe 405 away from the outlet pipe 403. Multiple vertical support rods 7 vertically support the entire weight of the support plate 8 and the upper sliding component. The support plate 8 has vertical through sliding holes to provide vertical sliding tracks for the support frame 9 and the connecting frame 10. The support frame 9 is rigidly fixed to the guide plate 502. When the guide plate 502 is raised or lowered, it directly drives the support frame 9 to move up and down along the sliding holes of the support plate 8. The water supply pipe 405 is raised and lowered synchronously with the support frame 9, and the nozzle 404 changes its working height synchronously to adapt to the spraying construction of niches and cliff statues of different heights.

[0036] The outlet pipe 403 is made of corrugated flexible hose material that can be freely bent and stretched to compensate for displacement difference as it rises and falls with the support frame 9, while the water supply pipe 405 is made of rigid hard water pipe that is not easily deformed.

[0037] The rotary adjustment mechanism 5 includes a guide rod 501 fixedly mounted vertically downward at the bottom of the support plate 8. A guide disc 502 is slidably fitted onto the outer surface of the guide rod 501. The bottom of the support frame 9 is fixedly connected to the top surface of the guide disc 502. The guide rod 501 is vertically fixed to the bottom of the support plate 8, serving as the only vertical sliding constraint track for the guide disc 502, restricting horizontal deviation and tilting of the guide disc 502. The inner hole of the guide disc 502 is clearance-fitted with the outer wall of the guide rod 501, resulting in low sliding resistance. The lifting force of the drive disc 503 can be smoothly transmitted to the support frame 9, ensuring that the nozzle 404 is vertically stable throughout its lifting process without lateral swaying.

[0038] A drive disk 503 is rotatably embedded in the inner top wall of the mounting box 3. An adjusting block 504 for lifting the guide disk 502 is symmetrically fixed on the upper surface of the drive disk 503. The adjusting block 504 has an arc-shaped block structure, and the top surface of the adjusting block 504 facing upward is an inclined surface 505. A mounting bracket 506 is symmetrically fixed downward at the bottom of the guide disk 502. A drive wheel 507 that can roll along the inclined surface 505 is embedded and rotatably mounted inside the bottom end of the mounting bracket 506. The drive wheel 507 is in close rolling contact with the inclined surface 505 of the adjusting block 504. When the drive disc 503 rotates in a circular motion, the two symmetrical arc-shaped adjusting blocks 504 rotate synchronously. The height of the inclined surface 505 on the adjusting block 504 changes continuously and gradually along the circumferential direction, and the drive wheel 507 continuously rolls in contact with the inclined surface 505. The support height of the drive wheel 507 changes synchronously with the position of the inclined surface. When the lower position of the inclined surface rotates to below the drive wheel 507, the guide disc 502 lowers as a whole. When the higher position of the inclined surface rotates to below the drive wheel 507, the guide disc 502 rises as a whole. The drive wheel 507 uses rolling friction instead of sliding friction, which greatly reduces the lifting transmission resistance and makes the lifting and adjusting action smooth and effortless.

[0039] A drive column 508 is fixedly installed at the bottom of the drive disc 503, and a drive gear 509 is fixedly installed at the bottom end of the drive column 508. A drive screw 5010 is rotatably installed inside the mounting box 3. A drive motor 5011 is fixedly installed inside the mounting box 3. The output shaft of the drive motor 5011 is fixedly connected to the end of the drive screw 5010 through a coupling. A positioning rod 5012 is also fixedly installed inside the mounting box 3. A drive block 5013 is threadedly connected to the outer surface of the drive screw 5010. The positioning rod 5012 passes through the drive block 5013 and is slidably connected to its inner surface. A drive gear plate 5014 is fixedly installed on one side of the drive block 5013, wherein the drive gear plate 5014 is meshed with the drive gear 509. The drive motor 5011 is the sole power source for this equipment. The output torque of the drive motor 5011 is transmitted to the drive screw 5010 via a coupling, causing it to rotate. The positioning rod 5012 passes laterally through the drive block 5013, restricting the drive block 5013 to rotate synchronously with the drive screw 5010, thus converting the rotational motion of the drive screw 5010 into the horizontal linear reciprocating motion of the drive block 5013. The drive block 5013 drives the drive gear plate 5014 to move laterally synchronously. The teeth of the drive gear plate 5014 mesh with the drive gear 509, converting the horizontal linear motion into the circumferential rotation of the drive gear 509. The drive gear 509 drives the upper drive disc 503 to rotate synchronously via the drive column 508, ultimately achieving the inclined plane lifting and lowering action. The forward and reverse rotation of the drive motor 5011 can control the left and right movement of the drive gear plate 5014, realizing the forward and reverse rotation of the drive disc 503, and completing the bidirectional adjustment of the nozzle 404 for raising and lowering.

[0040] A connecting frame 10 is slidably mounted on the support plate 8. A connecting shaft 11 is rotatably mounted on the end of the connecting frame 10 away from the support plate 8. The bottom end of the connecting shaft 11 extends into the interior of the storage tank 2. The stirring rod 6 is fixedly mounted on the outer surface of the connecting shaft 11. The connecting frame 10 and the support frame 9 are synchronously slidably assembled in the sliding hole of the support plate 8. The guide plate 502 moves up and down, causing the support plate 8 to move up and down as a whole. The connecting frame 10 moves vertically back and forth synchronously with the support plate 8. The connecting shaft 11 is rotatably mounted on the bottom end of the connecting frame 10 and can rotate freely relative to the connecting frame 10. The stirring rod 6 is circumferentially fixed in the section of the connecting shaft 11 that is immersed in the medicine liquid. When the connecting shaft 11 rotates, the stirring rod 6 stirs the medicine liquid synchronously and moves up and down with the connecting frame 10, realizing full-range high-level reciprocating stirring of the stirring rod 6.

[0041] A guide sleeve 12 is vertically and sealed and fixedly installed through the center of the inner top wall of the storage box 2. The inner surface of the guide sleeve 12 is provided with a spiral guide groove 1201 that limits the lifting and rotating trajectory of the connecting shaft 11. A limiting protrusion 1101 is fixedly provided on the outer surface of the connecting shaft 11. The outer end of the limiting protrusion 1101 is slidably embedded in the groove of the spiral guide groove 1201. The guide sleeve 12 remains fixed, and the internal spiral guide groove 1201 follows a fixed spiral trajectory. When the connecting shaft 11 moves vertically up and down with the connecting frame 10, the externally protruding limiting protrusion 1101 of the shaft is constrained to slide inside the spiral guide groove 1201. The vertical linear displacement is converted into the circular rotation of the connecting shaft 11 by the spiral guide groove 1201. During the entire process of the guide disc 502 rising and falling, the limiting protrusion 1101 continues to slide along the spiral guide groove 1201, and the stirring rod 6 moves up and down while continuously rotating, synchronously turning over the upper, middle, and lower layers of the medicine in the storage tank 2, thus completely solving the problem of sedimentation and stratification of the mineralized suspension.
