Description

Technical Field

[0001] The present invention relates to the technical field of concrete monitoring and maintenance of electric power infrastructure projects, and in particular to a concrete monitoring and maintenance device based on electric power infrastructure projects. Background Art

[0002] In power construction, the foundations of many infrastructure facilities such as high-voltage towers are constructed by pouring concrete. During construction and installation, a foundation pit is first dug at the construction site, and then the foundation is constructed by pouring concrete. Because high-voltage towers have very high requirements on the stability of the bottom foundation, when the towers are installed, it is required that there should not be too much settlement at the bottom. Therefore, special attention should be paid to the maintenance of the concrete during the construction of the bottom foundation to avoid safety hazards to the towers due to poor quality of the bottom foundation.

[0003] After concrete pouring, if the climate is hot and the air is dry, if it is not maintained in time, the moisture in the concrete will evaporate too quickly, resulting in dehydration. The cement particles that have formed a gel cannot be fully hydrated and cannot be converted into stable crystals. The lack of sufficient bonding force will cause flakes or powders to fall off on the concrete surface. In addition, when the concrete does not yet have sufficient strength, premature evaporation of moisture will also cause large shrinkage deformation and shrinkage cracks. Therefore, the maintenance of the initial stage after concrete pouring is very important. The concrete should be maintained immediately after final setting, and the dry hard concrete should be maintained immediately after pouring.

[0004] The existing Chinese patent with patent number CN112922368B authorizes an intelligent concrete monitoring and maintenance device for power infrastructure projects, including two bases arranged opposite to each other and placed on the periphery of concrete infrastructure facilities, a height-adjustable support component is installed on the top of each of the two bases, and an annular guide rail fixed on the top of the two support components is arranged above the two support components, and a trolley that moves in a circle along its annular length is arranged on the annular guide rail, and a sprinkler assembly for watering and maintaining the concrete infrastructure facilities is fixed at the bottom of the trolley, and also includes a water supply assembly that provides water to the sprinkler assembly and a control system that controls the trolley to perform reciprocating circular motion along the annular guide rail.

[0005] When the above device is in use, an annular guide rail is installed on the outside of the concrete foundation of the power infrastructure, and then the bottom foundation of the concrete is sprayed with water for maintenance by carrying a sprinkler assembly on a vehicle. However, it is difficult to cover the surface of the concrete infrastructure during actual use. When the external temperature is too high, it is easy to cause the moisture on the concrete surface to evaporate faster, affecting the maintenance effect of the concrete infrastructure.

[0006] To this end, we proposed a concrete monitoring and maintenance device based on power infrastructure projects. Summary of the invention

[0007] The purpose of the present invention is to provide a concrete monitoring and maintenance device based on power infrastructure projects, which has the advantage of covering the surface of concrete infrastructure and solves the problems in the background technology.

The two rectangular plates are provided with n-shaped grooves for limiting the two ends of the rollers. The outer contours of the two rollers are rolled up and accommodated with a curing film that covers the surface of the concrete infrastructure. The ends of the two curing films away from the rollers are fixedly connected to the symmetrical positions at both ends of the positioning frame respectively. The rectangular plates are provided with a moving mechanism that drives the rollers to move back and forth toward and away from each other.

[0011] Preferably, the moving mechanism includes adjusting rods at symmetrical positions on both sides of the opposite surfaces of the two rectangular plates, which are rotatably connected to the rollers through pins for reciprocating movement toward and away from each other. Each of the adjusting rods is provided with a rectangular through groove, and the inner walls of the rectangular through grooves are movably connected with adjusting blocks for supporting the rollers. The two adjusting blocks on each side are respectively penetrated by the rollers and rotatably connected, and a torsion spring is fixedly connected to the opposite surfaces of the adjusting blocks at both ends of each roller.

[0012] Preferably, rectangular slide grooves are provided at symmetrical positions on both sides of the movable frame corresponding to the adjusting rod, and sliders are movably connected at symmetrical positions at both ends of the inner wall of the rectangular slide groove on each side, and one end of the two adjusting rods on each side close to the movable frame is rotatably connected to the slider through a pin shaft, and fixed blocks are fixedly connected at the center position of the inner wall of the rectangular slide groove on both sides, and springs for supporting the slider are fixedly connected to the surfaces opposite to the slider on both sides of each fixed block.

[0013] Preferably, the positioning frame is fixedly connected to a base at one end close to the rectangular frame, a water tank for storing water source is fixedly connected to one side of the base, a cylindrical shell is fixedly connected to one side of the base close to the water tank, and a water inlet pipe and a drain pipe are fixedly connected to the inner wall at symmetrical positions on both sides of the cylindrical shell close to one end of the rectangular frame, an end of the water inlet pipe away from the cylindrical shell is penetrated to the inner wall of the water tank and fixedly connected, and an end of the drain pipe away from the cylindrical shell is penetrated to the inner wall of the annular pipe and fixedly connected.

[0014] Preferably, the cylindrical shell is provided with a pumping mechanism for quantitatively extracting and discharging water from inside the water tank, the pumping mechanism includes a piston plate movably connected to the inner wall of the cylindrical shell for extracting and discharging water from inside the water tank, the piston plate is fixedly connected to a moving rod at one end away from the water inlet pipe, the water inlet pipe is fixedly connected to an inner wall near one end of the cylindrical shell with a one-way liquid inlet valve for quantitatively extracting water from the water tank into the cylindrical shell, and the drain pipe is fixedly connected to an inner wall near one end of the cylindrical shell with a one-way liquid discharge valve for quantitatively discharging water from the cylindrical shell.

[0015] Preferably, one end of the movable frame is fixedly connected to a connecting seat on a side away from the water tank, and a connecting rod is rotatably connected to the connecting seat through a pin shaft to pull the movable rod to perform axial reciprocating movement on the inner wall of the cylindrical shell, and the end of the connecting rod away from the connecting seat is rotatably connected to the end of the movable rod away from the piston plate through a pin shaft.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. When the temperature sensor monitors that the ambient temperature is lower than the set threshold, the temperature sensor starts the motor to drive the threaded rod to rotate clockwise, and the threaded rod is threadedly connected to the threaded sleeve. At this time, the threaded sleeve drives the moving frame to move toward the direction close to the positioning frame to the limit distance under the action of the threaded rod. When the temperature sensor monitors that the ambient temperature is higher than the set threshold, the temperature sensor starts the motor to drive the threaded rod to rotate counterclockwise. At this time, the threaded sleeve drives the moving frame to move away from the positioning frame to the limit distance under the action of the threaded rod. Then, the threaded sleeve can drive the moving frame to move up and down reciprocatingly under the action of the threaded rod. At the same time, the annular tube and the atomizing nozzle are synchronously lifted and reciprocated with the moving frame, thereby increasing the spraying range of the atomizing nozzle, so that the atomizing nozzle can evenly spray water on the surface of the concrete infrastructure, thereby improving the maintenance effect of the concrete infrastructure.

[0018] Second, as the moving frame moves in a direction away from the positioning frame, the slider pulls the adjusting rod away from the end of the rectangular plate to move toward each other under the action of the moving frame, so that the adjusting block pulls the roller along the inner wall of the n-shaped groove to reset toward each other under the action of the adjusting rod. At this time, the roller rolls and releases the curing film, and the torsion spring rotates and contracts under the action of the roller, so that the roller can cover the surface of the concrete infrastructure with the curing film, which can slow down the evaporation of water on the surface of the concrete infrastructure and further improve the curing effect of the concrete infrastructure.

[0019] 3. The roller is in contact with the surface of the concrete infrastructure, and as the roller moves back and forth along the inner wall of the n-shaped groove, the roller can roll the surface of the concrete infrastructure, thereby improving the density of the surface layer of the concrete infrastructure and reducing the occurrence of plastic cracks.

[0020] Fourth, as the moving frame moves toward the direction close to the positioning frame, the connecting rod can push the moving rod and the piston plate to move axially in the direction away from the water inlet pipe under the action of the moving frame, and the internal air pressure of the cylindrical shell near one end of the water inlet pipe is negative pressure, through the one-way liquid inlet valve and the one-way liquid discharge valve provided on the water inlet pipe and the discharge pipe, at this time, the one-way liquid inlet valve is in an open state, and the one-way liquid discharge valve is in a closed state, so that the water inlet pipe can draw water from the water tank to the inner wall of the cylindrical shell, and the moving frame moves in the direction away from the positioning frame. When the piston plate is pushed down, the connecting rod moves axially toward the water inlet pipe under the action of the moving frame, and the internal air pressure of the cylindrical shell near one end of the water inlet pipe is positive. At this time, the one-way liquid inlet valve is closed and the one-way liquid discharge valve is opened. Then, the drain pipe can discharge the water source inside the cylindrical shell to the inner wall of the annular pipe and the atomizing nozzle, and the moving frame can drive the annular pipe and the atomizing nozzle to move to spray the water source evenly onto the surface of the concrete infrastructure, thereby realizing quantitative extraction and discharge of water source and avoiding waste of water source.

[0021] The coordinated use of the above structure solves the problem that the existing device is difficult to cover the surface of the concrete infrastructure during actual use, and when the external temperature is too high, it is easy to cause the moisture on the concrete surface to evaporate faster, affecting the maintenance effect of the concrete infrastructure.

[0042] Embodiment three:

[0043] See also Figures 1 to 6 On the basis of the second embodiment, further:

[0044] The moving mechanism includes adjusting rods 11 symmetrically connected to the rollers 10 through pins on both sides of the opposite surfaces of the two rectangular plates 9 for reciprocating movement toward and away from each other. Each of the adjusting rods 11 is provided with a rectangular through groove 111, and the inner wall of the rectangular through groove 111 is movably connected with an adjusting block 12 for supporting the roller 10. The two adjusting blocks 12 on each side are respectively penetrated by the roller 10 and rotatably connected, and a torsion spring 13 is fixedly connected to the opposite surface of the adjusting block 12 at both ends of each roller 10.

[0045] Rectangular slide grooves 501 are provided at symmetrical positions on both sides of the movable frame 5 corresponding to the adjusting rod 11, and sliders 15 are movably connected at symmetrical positions at both ends of the inner wall of the rectangular slide groove 501 on each side. One end of the two adjusting rods 11 on each side close to the movable frame 5 is rotatably connected to the slider 15 through a pin shaft, and a fixed block 14 is fixedly connected to the center position of the inner wall of the rectangular slide groove 501 on both sides, and springs 16 for supporting the slider 15 are fixedly connected on the opposite surfaces of each fixed block 14 on both sides to the slider 15.

[0046] like Figures 1 to 5As shown, by the rectangular slot 501 provided on the moving frame 5 and the slider 15 provided on the rectangular slot 501, the rectangular slot 501 can limit the movement of the slider 15, and by the adjusting rod 11 provided on the rectangular plate 9, and the adjusting rod 11 is rotatably connected with the slider 15 on the adjacent side through the pin shaft, when the moving frame 5 moves toward the direction close to the positioning frame 1, the slider 15 moves in the opposite direction along the inner wall of the rectangular slot 501 under the support of the adjusting rod 11, and by the fixing block 14 provided on the rectangular slot 501 and the spring 16 provided on the fixing block 14, the spring 16 is stretched under the action of the slider 15, and at the same time, the end of the adjusting rod 11 away from the rectangular plate 9 is moved toward The roller 10 is rotated in opposite directions through the rectangular through groove 111 provided on the adjusting rod 11 and the adjusting block 12 provided on the rectangular through groove 111, so that the adjusting block 12 supports the roller 10.

At this time, the roller 10 rolls and releases the curing film 17, and the torsion spring 13 rotates and contracts under the action of the roller 10, so that the roller 10 can cover the surface of the concrete infrastructure with the curing film 17, which can slow down the evaporation of moisture on the surface of the concrete infrastructure and further improve the curing effect of the concrete infrastructure. When the roller 10 moves to the horizontal position of the n-shaped groove 901, the slider 15 moves toward each other under the pulling force of the spring 16.

[0048] The roller 10 is in contact with the surface of the concrete infrastructure, and as the roller 10 moves back and forth along the inner wall of the n-shaped groove 901, the roller 10 can roll the surface of the concrete infrastructure, thereby improving the density of the surface layer of the concrete infrastructure and reducing the occurrence of plastic cracks.
