[0021] It is worth mentioning that a conveying port 6 is opened on the top wall of the monitoring box 11, and the inner walls on both sides of the conveying port 6 are rotatably connected with pressing plates 61. After the building model is conveyed to the inside of the monitoring box 11 through the conveying port 6, the two pressing plates 61 are changed from an upward swinging state to a downward swinging state, so that the two pressing plates 61 can be pressed on the upper wall of the building model. The pressing plates 61 are made of soft steel material, which is heavy and flexible, so they can provide sufficient weight and pressing force to fix the building model and protect the building model from damage.

[0022] The monitoring mechanism 2 is used to comprehensively monitor the data of the building model. The monitoring mechanism 2 includes a spiral track 21 fixedly connected to the inside of the monitoring box 11. The inside of the monitoring box 11 is slidably connected with a lifting ring 22. The upper end of the base 1 is fixedly connected with a motor 23. The output end of the motor 23 is fixedly connected with a screw 24. The screw 24 is threadedly connected with a lifting block 25 fixedly connected to the lifting ring 22. A rotating ring 26 is rotatably connected to the inner wall of the lifting ring 22. A supporting block 27 is fixedly connected to the rotating ring 26. An inner fixed cylinder 28 is fixedly connected to the supporting block 27.

The limiting groove 5 can limit the lifting block 25 to prevent the lifting block 25 from rotating with the screw 24.

[0023] Specifically, the infrared detector 211 is fixedly connected to the two mounting plates 38 by pins, and only the pins need to be pulled out during disassembly, so that the infrared detector 211 can be replaced with a laser scanner or other monitoring equipment, making the monitoring data information more comprehensive.

[0024] In order to avoid the shaking of the building model during the rotation of the building model in the prior art, it is necessary to set up another clamping mechanism to fix the building model, which not only increases unnecessary production costs, but also inevitably causes obstruction of some areas around the building model when the building model is clamped, resulting in reduced comprehensiveness of monitoring the building model. In the present invention, a monitoring mechanism 2 is set up. When monitoring the building model, the motor 23 drives the screw 24 to rotate, so that the lifting block 25 can drive the lifting ring 22 to move vertically. During this process, the guide wheel 210 will rotate along the spiral track 21, so that the rotating ring 26 rotates relative to the lifting ring 22, so that the infrared detector 211 can rotate synchronously during the up and down movement, so that the infrared detector 211 can fully monitor the data of the building model from all heights and angles, without the need to rotate the building model, and at the same time, there is no need to set up another clamping mechanism. While reducing the production cost of the device, it avoids obstruction of the surrounding area of ​​the building model, making the monitoring of the building model more comprehensive.

[0025] The swing mechanism 3 is used to swing the infrared detector 211 up and down to increase the monitoring range when the infrared detector 211 is working.

The end of the inner fixed cylinder 28 away from the support block 27 is fixedly connected to a mounting block 36. A rotating rod 37 is rotatably installed on the side wall of the mounting block 36. The rotating rod 3 The two sides of the mounting block 7 are fixedly connected with mounting plates 38, the infrared detector 211 is fixedly connected between the two mounting plates 38, the middle position of the rotating rod 37 is fixedly connected with a gear 39, the side wall of the mounting block 36 is slidably connected with a rack 310 in the vertical direction, the rack 310 and the gear 39 are meshed with each other, a control chamber 311 is opened inside the mounting block 36, a piston block 312 is sealed and slidably connected inside the control chamber 311, a U-shaped rod 313 is fixedly connected between the upper end of the piston block 312 and the rack 310, and the two ends of the inner fixed cylinder 28 are respectively connected with the control chamber 311 and the inside of the liquid storage tank 31; Specifically, the interior of the inner fixed cylinder 28 , the space below the piston block 312 in the control chamber 311 , and the space on one side of the liquid storage tank 31 close to the support block 27 are all filled with hydraulic oil.

[0026] In order to improve the accuracy of the monitoring data, the present invention sets a swing mechanism 3. When the guide wheel 210 moves along the spiral track 21, the guide wheel 210 will rotate under the action of friction, thereby driving the outer rotating cylinder 29 to rotate relative to the inner fixed cylinder 28, so that the thread block on the outer rotating cylinder 29 can reciprocate horizontally along the reciprocating thread section 33, thereby driving the piston plate 32 to move back and forth inside the liquid storage tank 31, continuously pumping the hydraulic oil in the control chamber 311 into the liquid storage tank 31 through the inner fixed cylinder 28, and continuously pumping the liquid storage tank 31. 1 returns to the control chamber 311, so that the piston block 312 in the control chamber 311 can perform reciprocating vertical displacement, and the rack 310 is pulled by the U-shaped rod 313 to perform reciprocating vertical displacement, so that the rotating rod 37 is reciprocated and rotated in opposite directions under the action of the gear 39, so that the mounting plate 38 can drive the infrared detector 211 to swing up and down back and forth, thereby improving the monitoring range of the infrared detector 211 on the building model, so that the same position of the building model can be detected by the infrared detector 211 multiple times, and the accuracy of the monitoring data is improved.

[0027] The cleaning mechanism 4 is used to automatically clean the monitoring position when the infrared detector 211 is working to prevent dust and dirt from reducing the monitoring accuracy. The cleaning mechanism 4 includes a first hydraulic cylinder 41 fixedly connected to the upper end of the mounting block 36 and a second hydraulic cylinder 42 fixedly connected to the lower end of the mounting block 36. The first hydraulic cylinder 41 and the second hydraulic cylinder 42 are both sealed and slidably connected with an extension rod 43, and the end of the extension rod 43 close to the center of the monitoring box 11 is fixedly connected to a cleaning block 44. A cleaning cavity 45 is opened inside one of the mounting plates 38, and a counterweight block 46 is sealed and slidably connected inside the cleaning cavity 45. A force spring 47 is provided between one side wall of the counterweight block 46 and the inner wall of the cleaning cavity 45. Two infusion hoses 48 are fixedly connected to the outer wall of the mounting plate 38. The space on both sides of the counterweight block 46 in the cleaning cavity 45 is connected to the first hydraulic cylinder 41 and the second hydraulic cylinder 42 through the two infusion hoses 48.

[0028] Specifically, the spaces on both sides of the counterweight 46 in the cleaning chamber 45 , the two infusion hoses 48 , the first hydraulic cylinder 41 and the second hydraulic cylinder 42 are also filled with hydraulic oil.

[0029] In view of the problem that the building model cannot be cleaned in the prior art, the dust and dirt attached to the surface of the building model cannot be removed, which reduces the monitoring accuracy of the building model. In the present invention, a cleaning mechanism 4 is provided. When the mounting plate 38 swings back and forth, the position of the counterweight block 46 in the cleaning chamber 45 will continuously change: When the mounting plate 38 drives the infrared detector 211 to swing upward, the component force of the weight block 46 itself is opposite to the elastic force of the force spring 47, so that the weight block 46 is displaced to one side in the control chamber 311, and the hydraulic oil in the space on this side is transported to the first hydraulic cylinder 41, and the hydraulic oil in the second hydraulic cylinder 42 is transported to the space on the other side, so that the upper cleaning block 44 and the lower cleaning block 44 can be displaced upward synchronously; When the mounting plate 38 drives the infrared detector 211 to swing downward, the component force of the weight of the counterweight block 46 itself is in the same direction as the elastic force of the force spring 47, so that the counterweight block 46 is displaced to the other side in the control chamber 311, and the hydraulic oil in the space on the other side is transported to the second hydraulic cylinder 42, while the hydraulic oil in the first hydraulic cylinder 41 is transported to the original space, so that the upper cleaning block 44 and the lower cleaning block 44 can be displaced downward synchronously, so as to realize the cleaning work of the monitoring position of the building model, and avoid the dust, dirt and other debris attached thereto from affecting the monitoring data of the building model. At the same time, the space between the two cleaning blocks 44 swings with the swing of the infrared detector 211, so as to avoid the cleaning block 44 from blocking the monitoring work of the infrared detector 211, thereby further improving the monitoring accuracy.

[0030] In addition, in the present invention, by providing a motor 23, the motor 23 can drive the screw 24 to rotate, so that the guide wheel 210 rises along the spiral track 21, driving the infrared detector 211 to spirally rise synchronously, thereby realizing comprehensive monitoring of the building model. At the same time, during the spiral rise of the guide wheel 210, the outer rotating cylinder 29 is rotated relative to the inner fixed cylinder 28 through the action of friction, driving the infrared detector 211 to swing back and forth, thereby improving the monitoring range of the building model. In addition, during the back and forth swinging of the infrared detector 211, the counterweight block 46 and the change in the force direction of the force spring 47 are used to clean the monitoring position of the building model. The overall linkage of the device is high, and the driving source used is relatively small, thereby achieving the purpose of energy saving and efficiency improvement.

[0031] The internal center position of the monitoring box 11 is fixedly connected to the fixed seat 7, the inner wall of the fixed seat 7 is sealingly and slidably connected to the ejection block 71, the inner top wall of the monitoring box 11 is fixedly connected to an annular liquid storage chamber 72, the inner wall of the annular liquid storage chamber 72 is sealingly and slidably connected to the annular block 73, the lower end of the annular block 73 is fixedly connected to a connecting rod 74, the parts of the two connecting rods 74 extending to the bottom of the annular liquid storage chamber 72 are fixedly connected to abutment rings 75, the lifting ring 22 moves up to the specified position and contacts the lower wall of the abutment ring 75, and a connecting pipe 76 is fixedly connected between the inside of the annular liquid storage chamber 72 and the inside of the fixed seat 7.

[0032] In addition, after the screw 24 drives the lifting block 25 and the lifting ring 22 to move up to a certain height, the guide wheel 210 disengages from the spiral track 21 to complete the detection work. At this time, the pressing plate 61 is pulled from the downward swinging state to the upward swinging state to release the fixation of the building template. The continued upward movement of the lifting ring 22 will push the abutment ring 75 to move upward, and the hydraulic oil in the liquid storage tank 31 is further transported to the fixing seat 7 through the connecting pipe 76 through the upward movement of the annular block 73, so that the ejection block 71 can be extended from the fixing seat 7, and the building model is automatically pushed out of the monitoring box 11, which is convenient for the staff to take out the building model and the operation is convenient.

[0033] The present invention can be explained by the following operation mode: The building model is conveyed into the monitoring box 11 through the conveying port 6, and then the two pressing plates 61 are changed from an upward swinging state to a downward swinging state, so that the two pressing plates 61 can be pressed on the upper wall of the building model; The motor 23 drives the screw rod 24 to rotate, so that the lifting block 25 can drive the lifting ring 22 to move vertically. During this process, the guide wheel 210 will rotate along the spiral track 21, so that the rotating ring 26 rotates relative to the lifting ring 22, so that the infrared detector 211 can rotate synchronously during the up and down movement, so that the infrared detector 211 can fully monitor the data of the building model from all heights and angles. The transmission module 12 can transmit the monitoring data to the BIM platform for data modeling and information integration; When the guide wheel 210 moves along the spiral track 21, the guide wheel 210 will rotate under the action of friction, thereby driving the outer rotating cylinder 29 to rotate relative to the inner fixed cylinder 28, driving the piston plate 32 to move back and forth inside the liquid storage tank 31, so that the piston block 312 in the control chamber 311 can perform reciprocating vertical displacement, so that the rotating rod 37 can reciprocate and rotate in opposite directions, and the infrared detector 211 can swing up and down back and forth, thereby improving the monitoring range of the infrared detector 211 on the building model; During the process of the mounting plate 38 swinging back and forth, the position of the counterweight block 46 in the cleaning chamber 45 will constantly change. When the mounting plate 38 drives the infrared detector 211 to swing upward, the upper cleaning block 44 and the lower cleaning block 44 will move upward synchronously. When the mounting plate 38 drives the infrared detector 211 to swing downward, the upper cleaning block 44 and the lower cleaning block 44 will move downward synchronously, so that the two cleaning blocks 44 will synchronously reciprocate up and down to achieve the cleaning work of the monitoring position of the building model. After the screw rod 24 drives the lifting block 25 and the lifting ring 22 to move up to a certain height, the detection work is completed. At this time, the pressing plate 61 is pulled from the downward swinging state to the upward swinging state, and the continued upward movement of the lifting ring 22 will push the abutment ring 75 to move upward, so that the ejection block 71 can be extended from the fixing seat 7, and the building model is automatically pushed out of the monitoring box 11.
