Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of thermal insulation material detection, in particular to a detection device for building external wall thermal insulation material. BACKGROUND

[0002] Building external wall thermal insulation material is a key building material developed under the background of global energy crisis, environmental protection demand and building energy saving standard upgrading. Its technical evolution and application popularization revolve around "reducing building energy consumption, improving living comfort, and ensuring structural safety". As the core carrier of building energy saving, it can reduce indoor and outdoor heat exchange by forming a thermal insulation layer, significantly reducing heating and cooling energy consumption. For example, in severe cold regions, heating energy consumption can be reduced by more than 50%, and in hot summer and warm winter regions, air conditioning energy consumption can be reduced by 30%-40% in summer. However, its application still faces three major pain points: imbalance between thermal insulation performance and safety, flammable organic materials, weak inorganic materials, construction quality affecting system life, insufficient adhesion strength, and excessive anchor spacing, which can easily lead to thermal insulation layer hollowing, falling off; poor environmental adaptability, easy to age and crack in high temperature and high humidity environments, resulting in thermal insulation performance degradation. In the prior art, the detection of building external wall thermal insulation material needs to be carried out through high-altitude operation by using scaffolding, a hanging basket or a climbing car. The traditional tool frame takes a long time to build, the high-altitude operation personnel face the risk of falling, and it is difficult to adapt to the detection needs of large-scale building clusters. In addition, the holes after sampling will damage the integrity of the thermal insulation layer, and if it is not repaired in time or not standardized, it is easy to cause rainwater infiltration, thermal insulation performance degradation and other secondary problems.

[0026] The detailed connection means is a known technology in the field, and the working principle and process are mainly introduced as follows.

[0027] Step 1: The staff transports the towing trailer 1 to the designated area outside the building to be detected by the engineering vehicle, ensures that the towing trailer 1 is in a stable parking state, and the staff operates the control console 6 to start the unmanned aerial vehicle landing station 2 and the charging device 7. The unmanned aerial vehicle landing station 2 automatically releases the sealing state of its cabin body to provide a channel for the take-off and landing of the first unmanned aerial vehicle 31 and the second unmanned aerial vehicle 41. The staff connects the connecting lines of the charging device 7 with the first unmanned aerial vehicle 31 and the second unmanned aerial vehicle 41 respectively to complete the power supply and ensure sufficient power supply during flight and operation; Step 2: After charging, the control console 6 sends a start instruction to the first unmanned aerial vehicle 31. The first unmanned aerial vehicle 31 flies to the target detection area of the building outer wall along the planned route according to the preset GPS positioning and visual navigation system. After arriving, the first unmanned aerial vehicle 31 internally controls the detection sensor 32, the first mechanical arm 33, the multi-stage electric telescopic rod 35, the micro motor 312, the micro electric telescopic rod 39, the first electric telescopic rod 315 and the first motor 319 to start. The detection sensor 32 first conducts a comprehensive appearance detection on the wall insulation material to identify whether there are defects such as cracking, bulging and falling off, and locks the representative sample collection point according to the detection result. The first mechanical arm 33 adjusts the position and angle of the support frame 34 through multi-joint linkage to align the sample collection point. Then the support frame 34 adheres to the wall to stabilize the sampling part. The multi-stage electric telescopic rod 35 is elongated to push the installation frame 36 to move forward until the front end of the installation frame 36 is completely attached to the building outer wall to ensure that it will not deviate during the subsequent sampling process. The micro motor 312 drives the sampling drill bit 313 to rotate at high speed through the telescopic rotating seat 311, and the annular limiting groove 314 rotates synchronously outside the limiting slider 310. The left and right micro electric telescopic rods 39 are synchronously elongated to push the limiting slider 310 to move forward. Under the cooperation of the annular limiting groove 314, the sampling drill bit 313 is fed forward along the straight limiting groove 37. The sampling drill bit 313 moves while driving the telescopic rotating seat 311 to synchronously stretch and contract to maintain the rotating state of the sampling drill bit 313. The limiting seat 38 further constrains the trajectory of the sampling drill bit 313. The sampling drill bit 313 retains the cylindrical sample in the inner cavity to complete the drilling sampling of the insulation material; Step 3: After sampling is completed, the micro electric telescopic rod 39 is shortened, driving the limiting sliding block 310 and the sampling drill bit 313 to retreat backward and completely separate from the wall surface. The first electric telescopic rod 315 on the upper and lower sides is extended, pushing the mounting seat 316 to the upper and lower sides outside the sampling drill bit 313. The first motor 319 drives the rotating rod 317 to rotate inward. Under the limiting action of the rotating rod 317 on the other side, the upper and lower two groups of rotating rods 317 jointly push the L-shaped blocking seat 318 to close inward, forming a baffle covering the front end opening of the sampling drill bit 313, so as to prevent the sample from falling during the subsequent flight movement. The first unmanned aerial vehicle 31 carries the sample back along the original route and lands in the unmanned aerial vehicle landing station 2. The first motor 319 on both sides reversely drives the rotating rod 317, so that the blocking seat 318 on the upper and lower sides opens outward. The staff can take out the sample from the inner cavity of the sampling drill bit 313 and store it in the specified storage container for subsequent laboratory detection. Step 4: After the first unmanned aerial vehicle 31 completes sampling, the second unmanned aerial vehicle 41 flies to the position of the sampling hole according to the preset route. The internal program of the second unmanned aerial vehicle 41 controls the second mechanical arm 42, the third electric telescopic rod 49, the second electric telescopic rod 45 and the electric screwdriver 48 to start. The second mechanical arm 42 moves the mounting plate 43 through multi-joint linkage, thereby adjusting the angle of the movable plugging component 5, so that its axis is completely aligned with the sampling hole. Then, the filling sealing cylinder 51 is slowly inserted into the inner cavity of the sampling hole. The third electric telescopic rod 49 is extended, pushing the electric screwdriver 48 on the translation mounting frame 47 to move forward, so that the screwdriver head is completely embedded in the screw groove at the end of the screw rod 56 in the movable plugging component 5. Under the continuous pushing force of the third electric telescopic rod 49, the filling sealing cylinder 51 is further inserted tightly in the sampling hole. The second electric telescopic rod 45 on the left and right sides is synchronously shortened, driving the clamping jaw 46 to rotate outward and releasing the clamping of the filling sealing cylinder 51. The electric screwdriver 48 is started, driving the screw rod 56 to screw forward in the inner cavity of the sleeve nut 54. The rear end of the screw rod 56 gradually enters the expansion tube 55. After the expansion tube 55 is axially extruded, the opening at the rear end of the expansion tube 55 radially expands and expands, so that its diameter increases and tightly fits with the inner wall of the sampling hole, and slightly embeds in the heat preservation material, forming a firm mechanical locking force. When the screw rod 56 moves to the end, its head extrudes the sleeve sealing head 52, pushing the sleeve sealing head 52 to move along the outer wall of the filling sealing cylinder 51 towards the wall surface. After the sleeve sealing head 52 contacts the wall surface, it further extrudes the annular air bag 53 on the outside. The air bag 53 bursts and releases the quick-drying glue inside. The quick-drying glue evenly fills the gap between the sleeve sealing head 52 and the wall surface, solidifies in a short time, fixes the position of the sleeve sealing head 52, and finally realizes the waterproof and dustproof sealing of the sampling hole.
