Description

Technical Field

[0001] The present invention relates to the technical field of building detection, and in particular to a building detection device based on communication technology. Background Art

[0002] At present, after the construction of a building, it is usually necessary to inspect the cracks and exposed steel bars of the building to ensure the qualification of the building after construction; the Chinese utility model patent with the publication number CN209980097U discloses a building quality inspection robot, which controls the opening of the building quality inspection machine by wireless means. After walking, the industrial computer transmits the environmental data map, ground gap imaging information, infrared temperature field information of the house ground surface, non-destructive testing information inside the house ground, temperature and / or humidity information stored in it to the electronic device connected to the wireless communication module through the wireless communication module, so as to realize the intelligent collection of indoor ground quality data, so as to enable the staff to analyze and deal with the detected defects in a targeted manner, avoiding the problem of poor accuracy caused by manual inspection.

[0003] The Chinese utility model patent with publication number CN219799257U discloses an intelligent building inspection device based on 5G communication. The device body is equipped with a flight module and a camera module, which can be used to obtain image data of buildings through aerial photography, and then identify building damage by observing the image data, replacing traditional manual inspections. The presence of the transmission module enables the device body to be connected to remote devices through the 5G network, allowing staff to remotely control the equipment to collect building data, thereby improving the efficiency of building damage identification work and minimizing labor costs.

[0004] In the related technology, the existing detection equipment can usually only perform detection in a single environmental location when inspecting a building, such as indoor detection or outdoor detection, and lacks the combination of indoor detection functions and outdoor detection functions. As a result, different detection equipment needs to be used according to the actual detection location during detection, which increases the complexity and cost of detection. In addition, most of the existing outdoor detection equipment uses drones carrying cameras and other sensors for detection, and the outdoor environment changes are too complicated. Although the drones in the prior art have the function of parachute protection, when the external airflow is too large, the parachute is easily blown over, thereby reducing the anti-fall protection performance of the drone.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Embodiment 1:

[0043] See attached Figure 1-10 A building detection device based on communication technology comprises a base 1 which can be electrically walked, a control box 2 with an open side fixedly connected to the top of the base 1, and a box door hinged at the open side, a take-off frame 3 fixedly connected to the top of the control box 2, an outdoor detection mechanism for detecting outdoor high-altitude buildings is arranged on the take-off frame 3, an indoor detection mechanism 5 for detecting indoor buildings is arranged inside the control box 2, a control panel 6 for wireless communication control of the outdoor detection mechanism is arranged on one side of the control box 2, and a controller 7 for wireless communication control of the indoor detection mechanism 5 is suspended on the control box 2;

[0044] Through the setting of the control panel 6, the outdoor detection mechanism can be remotely controlled, and the outdoor detection mechanism can be used to perform detection work on the outdoor of the building. Through the setting of the controller 7, the indoor detection mechanism 5 can be remotely controlled, and the indoor detection mechanism 5 can be used to perform detection work on the indoor of the building. There is no need for staff to walk back and forth indoors, and the detection work indoors and outdoors of the building is effectively combined, thereby improving the convenience and comprehensiveness of the detection device.

[0045] The outdoor detection mechanism includes a drone 4, wherein a shaking sensor, a signal transceiver, a storage module, an energy supply module and a central control module are installed inside the drone 4, a first camera 41 with an adjustable angle is installed at the bottom of the drone 4, a housing 42 is fixedly connected to the top of the drone 4, an anti-fall component is arranged inside the housing 42, and an auxiliary component 8 for strengthening the anti-fall protection of the anti-fall component is arranged at the bottom of the drone 4;

[0046] The drone 4 in the outdoor detection mechanism can drive the first camera 41 to take off, so as to detect locations such as outdoor high-rise building walls. The anti-fall component set inside the shell 42 can prevent the drone 4 from falling rapidly due to losing stability, and the setting of the auxiliary component 8 can further improve the anti-fall performance of the drone 4, thereby solving the problem in the prior art that the outdoor detection mechanism cannot perform anti-fall protection when encountering high-intensity airflow when flying at high altitudes.

[0047] See attached Figures 8 to 10 The anti-falling assembly includes a through pipe 44 fixedly connected to the top of the shell 42, a rubber cap 45 for blocking the through pipe 44 is fixedly connected to the outer surface of the shell 42 through a rope, a lifting plate 46 is slidably connected to the inside of the through pipe 44, a parachute 47 and a plurality of push rods 43 are fixedly connected to the top of the lifting plate 46 through a rope, and an elastic member 48 for pressing the lifting plate 46 upward and an electric locking member 49 for locking the lifting plate 46 are provided at the bottom of the inner wall of the shell 42;

[0048] By setting the electric locking member 49, the lifting plate 46 can be electrically locked after being stored downwards, so as to ensure the stability of the parachute 47 inside the through pipe 44. By setting the rubber cap 45, the user can protect the top of the through pipe 44 to prevent external gas from entering the through pipe 44, causing the parachute 47 to open automatically, thus affecting the stability of subsequent high-altitude detection work.

[0049] By setting the elastic member 48, the lifting plate 46 that loses the locking can be driven to move upward, and then the parachute 47 and the push rod 43 can be driven to move upward. Through the upward movement of the push rod 43, the rubber cap 45 can be pushed open, and the parachute 47 is ejected to the outside of the through tube 44, forming the deployment protection work of the parachute 47.

[0050] See attached Fig. 9 The elastic member 48 includes two guide rods 481 fixed inside the housing 42, the outer surfaces of the two guide rods 481 are sleeved with connecting plates 482, and the two connecting plates 482 are fixedly connected to the lifting plate 46, and the bottoms of the two connecting plates 482 and the housing 42 are fixedly connected with springs 483;

[0051] The two guide rods 481 are provided to improve the smoothness and stability of the up and down sliding of the connecting plate 482. The elastic force of the spring 483 itself can squeeze the connecting plate 482 upward, so that the connecting plate 482 drives the unlocked lifting plate 46 to move upward, forming the parachute 47 to open and work, so as to protect the falling drone 4 through the parachute 47 and avoid damage to the drone 4 that loses its balance and falls at high speed.

[0052] See attached Figure 6 and Figure 7The auxiliary component 8 includes a U-shaped frame 81 fixed to the bottom of the drone 4, the U-shaped frame 81 is rotatably connected to a winding wheel 82, two winding wheels 82 are wound with connecting ropes 83, the bottom ends of the connecting ropes 83 extend to the bottom of the U-shaped frame 81, and the bottom ends of the connecting ropes 83 are fixedly connected to a conical gravity block 84, both ends of the winding wheel 82 are fixedly connected to circular blocks 85, and the outer surfaces of the two circular blocks 85 are provided with limiting grooves, and the U-shaped frame 81 is provided with two control members 86 for rotating and locking the circular blocks 85;

[0053] By locking the two circular blocks 85 with the control member 86, the stability of the conical gravity block 84 after storage can be ensured, and the drone 4 can perform outdoor detection work normally;

[0054] On the contrary, by losing the locking of the circular block 85 by the control member 86, the conical gravity block 84 can move downward with its own gravity, thereby driving the winding wheel 82 to rotate, so that the connecting rope 83 is unwound, thereby changing the distance between the conical gravity block 84 and the UAV 4, improving the stability of the chassis position of the UAV 4, and preventing the UAV 4 from tipping over during flight.

[0055] See attached Figure 7 The control member 86 includes a pipe 861 fixed between the housing 42 and the U-shaped frame 81, and the top and bottom ends of the pipe 861 are slidably connected with T-shaped pistons 862, the T-shaped piston 862 located at the top is fixedly connected to the connecting plate 482, and the T-shaped piston 862 located at the bottom is fixedly connected with a T-shaped limit block 863 for inserting into the limit groove, and the T-shaped limit block 863 is slidably connected to the inside of the U-shaped frame 81;

[0056] When the connecting plate 482 in the elastic member 48 moves upward, the T-shaped piston 862 located above can be driven to move upward. Since the internal pressure of the pipe 861 is in a constant state, when the upper T-shaped piston 862 moves upward, the negative pressure inside the pipe 861 can drive the lower T-shaped piston 862 to move upward synchronously, thereby driving the T-shaped limit block 863 to move upward and move out from the inner part of the upper limit groove on the circular block 85, thereby losing the locking of the circular block 85, thereby facilitating the descent of the conical gravity block 84 and improving the stability of the center of gravity of the drone 4.

[0057] The two T-pistons 862 slide inside the pipe 861 in a sealed sliding manner, so that when one of the T-pistons 862 moves up and down, it can synchronously drive the other T-piston 862 to move up and down, forming a transmission operation.

[0058] Embodiment 2: Based on embodiment 1, the difference is that;

[0059] See attached Fig. 9 and Fig.10 The electric locking member 49 includes two clamping plates 491 fixed to the bottom of the lifting plate 46, and the bottom of the two clamping plates 491 is provided with a locking hole, and the bottom of the inner wall of the shell 42 is slidably connected to two T-shaped locking blocks 492 for inserting into the locking hole, and the two T-shaped locking blocks 492 are hinged on the opposite sides of the two first support rods 493 and the second support rods 494, and an extrusion plate 495 is hinged between one end of the two first support rods 493, and a V-shaped metal spring 496 for elastically extruding the extrusion plate 495 is fixedly connected inside the shell 42, and a metal plate 497 is hinged between one end of the two second support rods 494, and the bottom of the metal plate 497 is slidably connected to the bottom of the inner wall of the shell 42, and the bottom of the inner wall of the shell 42 is fixedly connected to an electromagnet 498 for adsorbing the metal plate 497 after power is turned on;

[0060] The squeezing plate 495 can be squeezed by the elastic force of the V-shaped metal spring 496, so that the squeezing plate 495 moves toward the position of the electromagnet 498, thereby driving the two first support rods 493 to move in a fan shape, thereby driving the two T-shaped locking blocks 492 to move away from each other, so that the protruding ends of the T-shaped locking blocks 492 are inserted into the locking openings at the corresponding positions, thereby locking the clamping plate 491, thereby ensuring the stability of the lifting plate 46 after its contraction;

[0061] When the built-in sensor of the drone 4 detects that the drone 4 loses balance, the electromagnet 498 is energized and controlled. The energization of the electromagnet 498 can generate electromagnetic force, thereby adsorbing the metal plate 497, causing the metal plate 497 to move toward the position of the electromagnet 498, thereby driving the two second support rods 494 to move in a fan shape, causing the two T-shaped locking blocks 492 to move in relative directions and move out from the inside of the two locking openings. With the elastic extrusion of the two groups of elastic parts 48, the lifting plate 46 can be lifted upward, allowing the parachute 47 to move out, forming a landing protection work.

[0062] Embodiment 3: Based on embodiment 1, the difference is that;

[0063] See attached Figure 2 and Figure 3 The indoor detection mechanism 5 includes a mounting frame 51 disposed inside the control box 2 and an extension member for extending and driving the mounting frame 51. The top of the mounting frame 51 is provided with an angle-adjustable laser radar 52 and a second camera 53;

[0064] Both the laser radar 52 and the second camera 53 use radar in the existing technology together with a CCD high-tech camera. The second camera 53 is used to cooperate with the laser radar 52. Once the laser radar 52 detects a gap in the ground within its range, the industrial computer controls the color camera to take pictures and images of the gap in the ground.

[0065] The extension member includes a bottom movable plate 54 slidably connected to the inner wall of the control box 2, one side of the movable plate 54 is slidably connected to a lifting frame 55 in an up-and-down sliding manner, one side of the lifting frame 55 is fixed to the bottom of the mounting frame 51, the front and back sides of the inner wall of the control box 2 are both provided with L-shaped inclined guide grooves 56, the inside of the lifting frame 55 is fixedly connected to a guide rod 57, the two ends of the guide rod 57 extend to the inside of the two inclined guide grooves 56 respectively, the inside of the control box 2 is fixedly connected to a motor 58, and the output shaft of the motor 58 is fixedly connected to a screw rod 59, and the screw rod 59 is connected to the inner thread of the movable plate 54;

[0066] The motor 58 is connected to an external power supply and a control switch, and is a forward and reverse motor. It is set up using the connection method and coding method of the prior art, and is used to drive the screw rod 59 to rotate forward and reverse. The forward and reverse rotation of the screw rod 59 can drive the movable plate 54 to reciprocate left and right, and then the laser radar 52 and the second camera 53 installed on the top of the mounting frame 51 can be driven by the lifting frame 55 to move out of the control box 2 to perform indoor detection work in the building;

[0067] By moving the guide rod 57 on the lifting frame 55 inside the two inclined guide grooves 56, the lifting frame 55 can move left and right along the trajectory of the inclined guide grooves 56 to form height adjustment, effectively linking the extension adjustment and height adjustment of the indoor detection mechanism 5, without the need for an additional electric drive source for driving, thereby improving the functionality and practicality of the detection mechanism.

[0068] It should be noted that the term "comprises" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article, or device that includes a series of elements includes not only those elements, but also includes other elements that are not explicitly listed, or also includes elements inherent to such process, method, article, or device.
