Description

Technical Field

[0001] This invention relates to the field of engineering surveying technology, and in particular to a device for measuring and collecting engineering quantities at engineering construction sites. Background Technology

[0002] In the construction of various projects such as building construction, road and bridge construction, and water conservancy and hydropower, accurate surveying and data collection are crucial for cost accounting, construction progress management, and quality acceptance. Traditional surveying methods primarily rely on total stations, RTK (Real-Time Kinematic) systems, and manual measurement with measuring tapes, requiring surveyors to enter the construction site and collect data point by point. However, these traditional methods suffer from the following technical problems in practical applications: low efficiency and high labor costs: For construction sites with large or complex terrain, such as deep foundation pits, high slopes, and tunnels, manual surveying requires frequent movement of instruments and equipment, setting up control points, resulting in long data collection cycles and the need for multiple people to work together, leading to high labor costs. Safety risks: Construction sites often present safety hazards such as falls from heights, mechanical collisions, and collapses. Surveyors must frequently enter dangerous areas to collect data, increasing the risk of accidents.

[0003] Therefore, developing an engineering construction site quantity surveying and acquisition device that can improve surveying efficiency, ensure operational safety, enhance data accuracy, and strengthen connection stability has significant engineering application value. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the background art by proposing an engineering construction site engineering quantity surveying and acquisition device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an engineering construction site quantity surveying and acquisition device, comprising a drone body, a laser surveying module, and a fixed bracket. A cylindrical mounting block is disposed below the drone body. Several evenly distributed connecting rods are fixedly mounted on the bottom of the mounting block. Connecting rings are fixedly mounted on the bottom of the connecting rods. A rotating groove is formed on the inner wall of the connecting ring, and a rotating ring is rotatably mounted within the rotating groove. The inner diameter of the rotating ring is larger than the inner diameter of the connecting ring. Two symmetrically arranged support rods are fixedly mounted on the outer wall of the rotating ring. The laser surveying module is disposed below the drone body. The bottoms of the two support rods are respectively fixedly connected to both sides of the laser surveying module. The fixed bracket is disposed below the laser surveying module.

[0006] In the above-mentioned engineering construction site quantity surveying and acquisition device, the fixed support consists of a fixed plate and a movable frame. Three movable frames are evenly distributed below the fixed plate. The top of the movable frame is hinged to the bottom of the fixed plate. The top of the fixed plate has an insertion through hole. An adjusting ring is rotatably installed on the outer side of the fixed plate. Three evenly distributed L-shaped locking slots are opened inside the fixed plate. A locking rod with a spring telescopic structure is inserted into the locking slot. One end of the locking rod extends into the insertion through hole and is fixedly installed with a locking tooth. The end of the locking rod away from the locking tooth has an inclined surface. Three evenly distributed extrusion blocks are fixedly installed on the inner ring wall of the adjusting ring. The extrusion blocks are inserted into the corresponding locking slots and contact the corresponding locking rods.

[0007] In the above-mentioned engineering construction site quantity surveying and acquisition device, the bottom of the laser surveying module is rotatably connected to an adjusting turntable, and the bottom of the adjusting turntable is fixedly installed with a fixing rod. The fixing rod is inserted into the insertion through hole, and a limit groove is opened on the outer wall of the fixing rod. The opening position of the limit groove corresponds to the installation position of the locking tooth.

[0008] In the above-mentioned engineering construction site quantity surveying and acquisition device, a ring-shaped limiting pad is fixedly installed on the inner wall of the rotating groove. The bottom of the limiting pad is fixedly connected to the inner wall of the rotating groove by a number of evenly distributed springs. The limiting pad has a number of evenly distributed limiting slots. A number of evenly distributed limiting blocks are fixedly installed at the bottom of the inner wall of the rotating groove. The installation positions of the limiting blocks correspond to the opening positions of the limiting slots. The limiting blocks are inserted into the corresponding limiting slots and are flush with the top of the limiting pad. A number of evenly distributed balls are rotatably installed at the bottom of the rotating ring, and the balls are in contact with the top of the limiting pad.

[0009] In the above-mentioned engineering construction site quantity surveying and acquisition device, a disc-shaped connecting block is fixedly installed at the bottom of the main body of the UAV. A ring-shaped connecting groove is opened on the outer wall of the connecting block, and a disc-shaped insertion groove is opened on the top of the mounting block. The inner diameter of the insertion groove is larger than the outer diameter of the connecting block. Two symmetrically arranged electric telescopic rods are fixedly installed in the insertion groove. A connecting plate is fixedly installed at the telescopic end of the electric telescopic rod. The connecting plate has an arc-shaped structure and is inserted into the connecting groove.

[0010] In the above-mentioned engineering construction site quantity surveying and acquisition device, two symmetrically arranged electric winding machines are fixedly installed inside the mounting block. A connecting steel wire is fixedly installed on the electric winding machine. The end of the connecting steel wire away from the electric winding machine passes through the mounting block and is fixedly connected to the bottom of the UAV body.

[0011] In the above-mentioned engineering construction site engineering quantity surveying and acquisition device, the outer wall of the adjusting turntable is provided with a ring-shaped connecting groove, the outer wall of the mounting block is provided with a ring-shaped auxiliary groove, and a number of L-shaped protective rods are provided between the connecting groove and the auxiliary groove, with the two ends of the protective rods slidably connected in the connecting groove and the auxiliary groove respectively.

[0012] In the above-mentioned engineering construction site quantity surveying and acquisition device, a hollow groove is provided inside the protective rod, a compression telescopic rod is fixedly installed inside the hollow groove, an expansion air bladder is filled inside the hollow groove, an overflow groove is provided at the bottom of the protective rod, the expansion air bladder is connected to the overflow groove, and several spring plates are fixedly installed on the outer wall of the overflow groove.

[0013] Compared with existing technologies, the advantages of this invention are: High mapping stability: By setting up structures such as rotating rings, support rods, limiting pads, and ball bearings, the laser mapping module can rotate smoothly relative to the UAV body. By using the cooperation of limiting blocks and limiting slots, the rotation angle is positioned in stages, which effectively reduces the shaking of the mapping module caused by airflow disturbances or body vibration, and ensures the continuity and accuracy of laser scanning data.

[0014] Reliable installation and connection: The embedded locking structure, consisting of connecting blocks, plug slots, electric telescopic rods, and connecting plates, allows for quick and secure connection between the UAV body and the mounting block. At the same time, the electric rewinder and connecting steel wire form a redundant safety connection, preventing the mapping module from falling directly even if the main connection fails, significantly improving the safety of equipment operation.

[0015] The fixed bracket features self-adaptation and anti-detachment: the locking rod and locking teeth in the fixed bracket cooperate with the limiting groove on the fixed rod to achieve quick locking and height adjustment of the adjustment dial; by rotating the adjustment ring, the squeezing block pushes the locking rod to move, which is convenient to operate and has uniform locking force, effectively preventing the laser mapping module from accidentally rotating or loosening relative to the fixed bracket during flight.

[0016] Equipped with active protection function: When the extrusion telescopic rod inside the protective rod is impacted, it can trigger the expansion airbag. After the airbag expands, it is squeezed out from the overflow groove and drives the spring plate to unfold outward, forming a buffer barrier. It can effectively absorb and buffer external impact force, avoid direct damage to the laser mapping module and the main body of the drone, and enhance the survivability of the device in complex construction sites.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0021] Reference Figures 1-8A surveying and data acquisition device for engineering construction sites includes a UAV main body 1, a laser surveying module 2, and a fixed support 3. The laser surveying module 2 is preferably a three-dimensional laser scanning radar, used for high-precision point cloud data acquisition of the construction site's terrain, structures, and material stockpiles.

[0022] A cylindrical mounting block 101 is disposed below the main body 1 of the UAV. Several evenly distributed connecting rods 102 are fixedly mounted on the bottom of the mounting block 101, and connecting rings 103 are fixedly mounted on the bottom of the connecting rods 102. A rotating groove 104 is formed on the inner wall of the connecting ring 103, and a rotating ring 105 is rotatably mounted within the rotating groove 104. The inner diameter of the rotating ring 105 is larger than the inner diameter of the connecting ring 103. Two symmetrically arranged support rods 106 are fixedly mounted on the outer wall of the rotating ring 105. The laser mapping module 2 is disposed below the main body 1 of the UAV, and the bottoms of the two support rods 106 are fixedly connected to both sides of the laser mapping module 2. Through this structure, the laser mapping module 2 can rotate freely horizontally relative to the main body 1 of the UAV to adjust the scanning direction or compensate for the yaw motion of the UAV.

[0023] The fixed support 3 is located below the laser mapping module 2 to provide support when the mapping device is landed, and can adaptively adjust the support posture according to the terrain.

[0024] Furthermore, the fixed bracket 3 consists of a fixed plate 301 and a movable frame 302. Three movable frames 302 are evenly distributed below the fixed plate 301, with their tops hinged to the bottom of the fixed plate 301. The top of the fixed plate 301 has an insertion through-hole 303, and an adjusting ring 304 is rotatably mounted on the outer side of the fixed plate 301. The fixed plate 301 has three evenly distributed L-shaped locking grooves 305, into which a spring-loaded locking rod 306 (with a spring inside, naturally pushing the locking rod 306 towards the center of the insertion through-hole 303) is inserted. One end of the locking rod 306 extends into the insertion through-hole 303 and is fixedly fitted with a locking tooth 307; the end of the locking rod 306 away from the locking tooth 307 has an inclined surface. Three evenly distributed pressing blocks 308 are fixedly installed on the inner ring wall of the adjusting ring 304. The pressing blocks 308 are inserted into the corresponding locking grooves 305 and contact the corresponding locking rods 306. When the adjusting ring 304 is rotated, the pressing blocks 308 slide along the inclined surface at the end of the locking rod 306, pushing the locking rod 306 to move outward against the spring force, thereby causing the locking teeth 307 to disengage from the locked position and achieve unlocking.

[0025] The bottom of the laser mapping module 2 is rotatably connected to an adjusting turntable 201, and a fixing rod 202 is fixedly installed at the bottom of the adjusting turntable 201. The fixing rod 202 is inserted into the insertion through hole 303. A circular limiting groove 203 is formed on the outer wall of the fixing rod 202, and the opening position of the limiting groove 203 corresponds to the installation position of the locking tooth 307. By inserting the locking tooth 307 into the limiting groove 203 at different heights, the relative height between the laser mapping module 2 and the fixed bracket 3 can be adjusted to adapt to different terrain landing or center of gravity adjustment needs.

[0026] The limiting structure of the rotating groove 104: A ring-shaped limiting pad 107 is fixedly installed on the inner wall of the rotating groove 104. The bottom of the limiting pad 107 is fixedly connected to the inner wall of the rotating groove 104 by several evenly distributed springs. Several evenly distributed limiting through grooves 108 are opened on the limiting pad 107, and several evenly distributed limiting blocks 109 are fixedly installed on the bottom of the inner wall of the rotating groove 104. The installation positions of the limiting blocks 109 correspond to the opening positions of the limiting through grooves 108, and the limiting blocks 109 are inserted into the corresponding limiting through grooves 108 and are flush with the top of the limiting pad 107. Several evenly distributed balls 110 are rotatably installed on the bottom of the rotating ring 105, and the balls 110 are in contact with the top of the limiting pad 107. Without external force, the limiting washer 107 is lifted by the spring, making its top surface higher than the top surface of the limiting block 109. The rolling friction of the ball 110 is small, and it rotates flexibly. When it is necessary to lock the rotation angle, the rotating ring 105 can be pressed down to compress the spring of the limiting washer 107. The limiting block 109 extends to the limit through groove 108 and locks with the ball 110 to achieve angle locking.

[0027] The connection structure between the UAV body 1 and the mounting block 101: A disc-shaped connecting block 111 is fixedly installed at the bottom of the UAV body 1. A ring-shaped connecting groove 112 is formed on the outer wall of the connecting block 111. A disc-shaped insertion groove 113 is formed at the top of the mounting block 101, with the inner diameter of the insertion groove 113 being larger than the outer diameter of the connecting block 111. Two symmetrically arranged electric telescopic rods 114 are fixedly installed within the insertion groove 113. A connecting plate 115 is fixedly installed at the telescopic end of the electric telescopic rod 114. The connecting plate 115 has an arc-shaped structure and is inserted into the connecting groove 112. During installation, after the connecting block 111 enters the insertion groove 113, the electric telescopic rod 114 pushes the connecting plate 115 into the connecting groove 112, achieving mechanical locking. When disassembly is required, the electric telescopic rod 114 retracts the connecting plate 115, allowing for separation.

[0028] Redundant safety connection structure: Two symmetrically arranged electric retractors 116 are fixedly installed inside the mounting block 101. A connecting steel wire 117 is fixedly installed on the electric retractor 116. The end of the connecting steel wire 117 away from the electric retractor 116 passes through the mounting block 101 and is fixedly connected to the bottom of the UAV body 1. During normal flight, the electric retractor 116 winds up the connecting steel wire 117 to keep it taut without affecting the main connection. When it is detected that the connecting block 111 has accidentally disengaged from the insertion slot 113 (e.g., by a proximity switch or tension sensor), the electric retractor 116 can actively release or wind up the connecting steel wire 117, which plays a role in buffering and suspension protection, preventing the mapping module from falling directly.

[0029] The protective structure of the protective rod 205: A circular connecting groove 204 is provided on the outer wall of the adjusting turntable 201, and a circular auxiliary groove 118 is provided on the outer wall of the mounting block 101. Several L-shaped protective rods 205 are arranged between the connecting groove 204 and the auxiliary groove 118, with both ends of the protective rods 205 slidably connected within the connecting groove 204 and the auxiliary groove 118, respectively. The protective rods 205 are distributed circumferentially, surrounding the outside of the laser mapping module 2 to form a cage-like protective frame.

[0030] More specifically, the protective rod 205 has a hollow groove 206 inside, and a compression telescopic rod 207 is fixedly installed inside the hollow groove 206 (the fixed end of the compression telescopic rod 207 is installed on the inner wall of the hollow groove 206, and the movable end faces outward). The hollow groove 206 is filled with an inflatable air bladder 208, and a compression plate is fixedly installed on the telescopic end of the compression telescopic rod 207, which is in contact with the inflatable air bladder 208. The bottom of the protective rod 205 has an overflow groove 209, and the inflatable air bladder 208 is connected to the overflow groove 209. Several spring plates 210 are fixedly installed on the outer wall of the overflow groove 209. When the protective rod 205 is impacted, the external force drives the compression telescopic rod 207 to compress. The compression plate pushes the expansion airbag 208 to increase its internal pressure. The airbag expands rapidly outward from the overflow groove 209 and opens the spring plate 210 to form a larger buffer layer, effectively absorbing the impact energy and protecting the internal laser mapping module 2. One of the protective rods 205 is fixedly connected and set on one side of the laser mapping module 2. The remaining protective rods 205 are connected in series by pull wires, which can ensure that the protective rods are evenly distributed after being pulled open. When the laser mapping module 2 needs to be used, they can be stacked together by pushing them manually.

[0031] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0032] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
