DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0027] In one embodiment, see Figure 1-Figure 4 A multifunctional prefabricated construction engineering quality detection device comprises a top plate 1, a dustproof shell 9 is fixed at the bottom of the top plate 1, an image recognition device is installed inside the dustproof shell 9, the image recognition device is electrically connected to a starting mechanism 5, the starting mechanism 5 is used to control the image recognition device to start, the bottom of the dustproof shell 9 is open, and a sealing mechanism 6 is installed at the opening, the sealing mechanism 6 is used to seal the dustproof shell 9, a moving seat 8 is provided below the top plate 1, the top of the moving seat 8 is connected to the top plate 1 through a buffer mechanism 3, the buffer mechanism 3 is used for elastic support of the moving seat 8, a groove body 10 is provided at the bottom of the moving seat 8, a roller 11 is rotatably connected inside the groove body 10, the bottom of the roller 11 extends to the outside of the groove body 10, the roller 11 is close to the side of the dustproof shell 9, the groove A plurality of air pressure grooves 14 are provided at the top of the body 10 and are evenly distributed. Push blocks 16 are connected to the slider inside the air pressure grooves 14. The push blocks 16 are fixedly connected to the tops of the air pressure grooves 14 through the first elastic member 15. A blowing mechanism 2 is provided between the dustproof shell 9 and the movable seat 8. The blowing mechanism 2 is used to blow air onto the road surface. An air cavity 13 is provided inside the movable seat 8. The air pressure grooves 14 are communicated with the air cavity 13. The air cavity 13 is connected to an air pipe 12. The other end of the air pipe 12 is connected to an air pressure mechanism 4. The air pressure mechanism 4 is connected to a support rod 7. When the gas generated by the blowing mechanism 2 is not sufficient to push all the push blocks 16, the air pressure mechanism 4 is used to drive the support rod 7 to move horizontally, so that the support rod 7 drives the starting mechanism 5 to operate and releases the sealing mechanism 6 from the dustproof shell 9.

[0028] In this embodiment, when the device detects cracks in the road surface, the top plate 1 drives the roller 11 to roll, and the blowing mechanism 2 blows air to the road surface. The gas passes through the groove body 10 along the road surface into the air pressure groove 14 and squeezes the push block 16, so that the gas inside the air pressure groove 14 enters the air cavity 13, and the gas inside the air cavity 13 is discharged from the air pipe 12 and drives the support rod 7 to move to the specified position through the air pressure mechanism 4. At this time, the image recognition device does not work, and the sealing mechanism 6 seals the dustproof shell 9. The sealing mechanism 6 seals the dustproof shell 9, which can effectively avoid the phenomenon that dust is adsorbed on the surface of the image recognition device and the shooting result is unclear during the detection of cracks in the road surface. The image recognition device can be a camera. When cracks appear on the road surface, part of the gas discharged by the blowing mechanism 2 will directly enter the crack and be absorbed by the crack, which results in that the gas entering the groove body 10 is insufficient to push all the push blocks 16, wherein one or more push blocks 16 inside the air pressure groove 14 are in the first elastic member 15. , and the first elastic member 15 can be a spring, so that the gas discharged from the air pipe 12 cannot drive the support rod 7 to move to the specified position through the air pressure mechanism 4. At this time, the support rod 7 releases the seal of the dust cover 9 through the sealing mechanism 6, and the bottom of the dust cover 9 is in an open state. At the same time, the support rod 7 controls the image recognition device to start working through the starting mechanism 5. The image recognition device shoots the road surface and uploads the image. The setting of the blowing mechanism 2 and the air pressure mechanism 4 can play a pre-recognition role for road cracks. The image recognition device does not need to shoot the entire road section, which reduces memory consumption. At the same time, when the staff analyzes the cracks, the staff does not need to deliberately find the section of the image with cracks, which is convenient for the staff to quickly analyze the road cracks and reduces the labor intensity of the staff. In addition, the buffer mechanism 3 can play a buffering role on the roller 11 through the moving seat 8, so that the roller 11 can move up and down with the ups and downs of the road surface, ensuring the smoothness of the roller 11 during the rolling process.

[0029] See also Figure 4 A sealing strip 17 is fixed on the top of the tank body 10, and the bottom of the sealing strip 17 has an arc groove adapted to the side wall of the drum 11, and the drum 11 is slidably connected to the arc groove; The sealing strip 17 can seal the gap between the roller 11 and the tank body 10, thereby preventing the gas discharged from the blowing mechanism 2 from passing over the top of the roller 11 and entering the other side of the roller 11. The sealing strip 17 has a limiting effect on the gas discharged from the blowing mechanism 2, so that the gas can smoothly enter the air pressure tank 14 and squeeze the push block 16, thereby ensuring the accuracy of the pre-detection result.

[0030] See also Figure 2The blowing mechanism 2 includes a blower 21 fixedly connected to the bottom of the top plate 1, and the blower 21 is connected to a plurality of branch pipes 22, and one end of the branch pipe 22 close to the movable seat 8 is inclined downward; When detecting cracks in the road surface, the blower 21 is started. Under the action of the blower 21, gas is discharged from the end of the branch pipe 22 and acts on the road surface. When cracks appear in the road surface, the gas discharged from the branch pipe 22 directly enters the crack and is absorbed by the crack, so that the gas entering the air pressure groove 14 corresponding to the branch pipe 22 cannot push the push block 16 inside the air pressure groove 14, and the gas discharged from the air pipe 12 cannot drive the support rod 7 to move to the specified position through the air pressure mechanism 4. At this time, the sealing mechanism 6 no longer seals the dust cover 9, and the starting mechanism 5 controls the image recognition device to start working. The image recognition device takes a picture of the road surface and uploads the image.

[0031] See also Figure 2 The buffer mechanism 3 includes a guide rod 31 which is fixedly connected to the top of the moving seat 8 and is symmetrically distributed. The guide rod 31 is provided with a second elastic member 32 on the outside. The two ends of the second elastic member 32 are respectively fixedly connected to the bottom of the top plate 1 and the top of the moving seat 8; The movable seat 8 is elastically supported by the second elastic member 32, so that the roller 11 can move up and down following the undulations of the road surface, effectively ensuring the smoothness of the roller 11 during rolling, wherein the second elastic member 32 can be a spring, and the guide rod 31 can play a limiting role on the movable seat 8, effectively improving the stability of the movable seat 8 during movement. In addition, in order to avoid interference of the up and down movement of the movable seat 8 with the air pipe 12, the air pipe 12 can be a hose.

[0032] See also Figure 5 and Figure 6 The pneumatic mechanism 4 includes a support seat 42 fixed on the top of the top plate 1, a pneumatic cylinder 41 is fixed on the top of the support seat 42, the pneumatic cylinder 41 is connected to the air pipe 12, a piston 43 is slidably connected inside the pneumatic cylinder 41, one end of the piston 43 is fixedly connected to the end of the support rod 7, a baffle 46 is fixed to the outside of the support rod 7, a guide plate 45 is fixed on the top of the top plate 1, the support rod 7 passes through the guide plate 45 and is slidably connected to the guide plate 45, a third elastic member 44 is fixed to a side of the baffle 46 close to the guide plate 45, and the other end of the third elastic member 44 is fixedly connected to the guide plate 45; When cracks appear on the road surface, part of the gas discharged by the blowing mechanism 2 will directly enter the cracks, resulting in that the gas entering the groove body 10 is insufficient to push all the push blocks 16. These push blocks 16 cannot squeeze the gas inside the air pressure groove 14 into the air cavity 13, and the air pressure inside the air pressure cylinder 41 is reduced. The support rod 7 automatically resets under the action of the push block 16 and the third elastic member 44. The third elastic member 44 can be a spring. When the support rod 7 is reset to a certain position, the support rod 7 releases the seal of the dustproof shell 9 through the sealing mechanism 6, and the bottom of the dustproof shell 9 is in an open state. At the same time, the support rod 7 controls the image recognition device to start working through the starting mechanism 5. The image recognition device shoots the road surface and uploads the image. When detecting cracks in the road surface, the image recognition device does not need to shoot the entire road section, which reduces memory consumption. At the same time, when the staff analyzes the cracks, the staff does not need to deliberately find the section of the image with cracks, which is convenient for the staff to quickly analyze the cracks in the road surface.

[0033] See also Figure 6 The starting mechanism 5 includes a mounting plate 51 fixed on the top of the top plate 1, a starting switch 52 is installed on the side of the mounting plate 51 close to the support rod 7, the starting switch 52 is electrically connected to the image recognition device, a stopper 53 is provided on the side of the starting switch 52 close to the support rod 7, the stopper 53 is connected to the mounting plate 51 through a holding component, the holding component is used to hold the initial position of the stopper 53, a first magnet 54 is fixed on one end of the stopper 53 close to the support rod 7, a magnetic strip 55 is provided on the side wall of the support rod 7, and the magnetic strip 55 has the same magnetic properties as the magnet; When no cracks appear on the road surface, under the action of the retaining assembly, the push rod 53 is in the initial position, and the push rod 53 is not in contact with the start switch 52. When cracks appear on the road surface, the support rod 7 is automatically reset under the action of the pneumatic mechanism 4, and the support rod 7 drives the magnetic strip 55 to move horizontally while resetting. When the magnetic strip 55 moves to the position of the first magnet 54, the magnetic strip 55 and the first magnetic strip 55 repel each other, thereby squeezing the push rod 53, so that the push rod 53 moves toward the direction of the start switch 52 until the push rod 53 squeezes the start switch 52, and the start switch 52 controls the image recognition device to work, thereby photographing the cracks in the road surface.

[0034] See also Figure 6 The holding assembly includes a fixed plate 56 fixedly connected to the stopper 53 and symmetrically distributed, the fixed plate 56 is fixedly connected to a slide bar 57, the slide bar 57 penetrates the mounting plate 51 and is slidably connected to the mounting plate 51, and the outside of the slide bar 57 is provided with a fourth elastic member 58, and the two ends of the fourth elastic member 58 are respectively fixedly connected to the fixed plate 56 and the mounting plate 51; When no cracks appear on the road surface, the push rod 53 is located in the initial position under the action of the fourth elastic member 58 and the fixed plate 56. At this time, the push rod 53 is not in contact with the start switch 52, and the start switch 52 does not control the operation of the image recognition device. The fourth elastic member 58 can be a spring, and the sliding rod 57 can play a limiting role on the fixed plate 56, which effectively improves the stability of the push rod 53 and the fixed plate 56 during movement.

[0035] See also Figure 3 and Figure 7 The sealing mechanism 6 includes fixed blocks 62 fixed on both sides of the dustproof shell 9 and symmetrically distributed, and a sealing plate 61 for sealing the bottom of the dustproof shell 9 is rotatably connected between the fixed blocks 62. A guide block 65 is fixed on the outer wall of the dustproof shell 9, and a push rod 64 is passed through the guide block 65. A push plate 63 for squeezing the sealing plate 61 is fixed at one end of the push rod 64, and a traction plate 67 is fixed at the other end of the push rod 64. A fifth elastic member 66 is fixed on the side of the traction plate 67 close to the guide block 65, and the other end of the fifth elastic member 66 is fixedly connected to the outer wall of the guide block 65, wherein the traction plate 67 is connected to the support rod 7 through a traction assembly. When the gas generated by the blowing mechanism 2 is insufficient to push all the push blocks 16, the support rod 7 no longer pulls the traction plate 67 through the traction assembly, thereby releasing the squeezing of the push plate 63 on the sealing plate 61; When there are no cracks on the road surface, the traction assembly pulls the traction plate 67. At this time, the traction plate 67 squeezes the sealing plate 61 through the push rod 64 and the push plate 63, so that the sealing plate 61 seals the bottom of the dustproof shell 9, which can effectively avoid the phenomenon that dust is adsorbed on the surface of the image recognition device during the road surface crack detection process, thereby ensuring the clarity of the shooting. When cracks appear on the road surface, the gas generated by the blowing mechanism 2 is not enough to push all the push blocks 16, and the support rod 7 is automatically reset under the action of the air pressure mechanism 4. At this time, the support rod 7 no longer pulls the traction plate 67 through the traction assembly. The traction plate 67 is automatically reset under the action of the fifth elastic member 66. The traction plate 67 drives the push plate 63 to move horizontally through the push rod 64, thereby releasing the squeezing state of the push plate 63 on the sealing plate 61. The sealing plate 61 automatically rotates downward under the action of gravity, thereby making the bottom of the dustproof shell 9 in an open state, wherein the fifth elastic member 66 can be a spring.

[0036] See also Figure 7 The traction assembly includes a bracket 610 fixedly connected to the outer wall of the dustproof shell 9, the bracket 610 is fixedly connected to a guide column 69, a guide groove is provided inside the guide column 69, both ends of the guide groove penetrate the side wall of the guide column 69, a moving plate 611 is fixed to the end of the support rod 7, and the moving plate 611 is fixedly connected to a traction rope 68, and the traction rope 68 passes through the inside of the guide groove and is fixedly connected to the traction plate 67; When there are no cracks on the road surface, the support rod 7 is located at the specified position under the action of the pneumatic mechanism 4. At this time, under the action of the guide column 69, the movable plate 611 at the end of the support rod 7 pulls the traction plate 67 through the traction rope 68, and the traction plate 67 squeezes the sealing plate 61 through the push rod 64 and the push plate 63, so that the sealing plate 61 seals the bottom of the dustproof shell 9. When cracks appear on the road surface, the gas generated by the blowing mechanism 2 is not enough to push all the push blocks 16. The support rod 7 automatically resets and drives the movable plate 611 to move horizontally, so that the traction rope 68 is in a relaxed state. At this time, the traction rope 68 no longer pulls the traction plate 67, and the traction plate 67 automatically resets. The traction plate 67 drives the push plate 63 to move horizontally through the push rod 64, thereby releasing the squeezing state of the push plate 63 on the sealing plate 61, and the sealing plate 61 automatically rotates downward under the action of gravity, so that the bottom of the dustproof shell 9 is in an open state.

[0037] See also Figure 7 A pin rod 615 is passed through the top of the guide block 65, and the pin rod 615 is connected to the top of the guide block 65 through a sixth elastic member 614. A second magnet 613 is fixed to the top of the pin rod 615, and a magnetic column 612 is fixed to the bottom of the support rod 7. The magnetic properties of the magnetic column 612 and the second magnet 613 are opposite. A pin groove adapted to the pin rod 615 is provided on the top of the push rod 64, and the lower end of the pin rod 615 is located inside the pin groove; When there are no cracks on the road surface, under the action of the traction assembly, the traction plate 67 squeezes the sealing plate 61 through the push rod 64 and the push plate 63, so that the sealing plate 61 seals the bottom of the dust cover 9. At this time, under the action of the sixth elastic member 614, the lower end of the pin rod 615 is located inside the pin groove at the top of the push rod 64. The sixth elastic member 614 can be a spring. At this time, the pin rod 615 fixes the push rod 64 through the pin groove, effectively improving the stability of the push rod 64, thereby ensuring the squeezing state of the push plate 63 on the sealing plate 61. When cracks appear on the road surface, the gas generated by the blowing mechanism 2 is not enough to push all the push blocks 16, and the support rod 7 automatically resets and drives the moving plate 611 to move horizontally, so that The traction rope 68 is in a relaxed state. At this time, the traction rope 68 no longer pulls the traction plate 67, and the support rod 7 is reset while driving the magnetic column 612 to move horizontally. As the support rod 7 is reset, the magnetic column 612 moves above the second magnet 613. Since the magnetic properties of the magnetic column 612 and the second magnet 613 are opposite, when the magnetic column 612 moves above the second magnet 613, the magnetic column 612 and the second magnet 613 attract each other, so that the second magnet 613 drives the pin rod 615 to move upward, and then pulls the pin rod 615 out of the pin groove. The pin rod 615 loses its limit, and the push rod 64 is automatically reset under the action of the traction plate 67 and the fifth elastic member 66, thereby releasing the squeezing state of the push plate 63 on the sealing plate 61.
