Description

Technical Field

[0001] This application relates to the field of height measurement technology, and in particular to a building height measuring device. Background Technology

[0002] Height measurement is a core element in ensuring building safety, compliance, and functionality, directly impacting structural stability, regulatory compliance, space utilization, and equipment operation requirements. Modern measurement techniques typically include total station surveying, 3D laser scanning, and satellite positioning systems.

[0003] Currently, building height measurement typically employs total station suspension measurement, which requires the assistance of a prism. The specific measurement process is as follows: First, the prism is placed at the reference point of the object to be measured. Then, the total station is aimed at the prism, and the distance from the total station to the prism is measured using the suspension measurement mode. Next, the telescope of the total station is rotated so that it can observe the top of the building. Finally, the height of the building can be calculated and output using the total station.

[0004] Regarding the aforementioned technologies, the placement of existing prisms usually requires manual placement. However, for special areas such as bridge piers and cranes, manual placement of prisms is cumbersome and poses a high safety hazard. Utility Model Content

[0005] To reduce the safety hazards of manually placing prisms, this application provides a building height measuring device.

[0006] The building height measuring device provided in this application adopts the following technical solution:

[0007] A building height measuring device includes a drone delivery body and an installation assembly disposed on the drone delivery body for mounting a prism. The installation assembly includes a mounting frame connected to the drone delivery body and a rotating seat rotatably mounted on the mounting frame. The prism is fixedly mounted on the rotating seat.

[0008] By adopting the above technical solution, the main body of the drone is transported and the installation components and prisms are carried, avoiding the tediousness and safety hazards of manually placing prisms in areas such as bridge piers and towers. The rotating mount can adjust the angle of the prism to adapt to different measurement needs.

[0009] Optionally, the rotating base has a positioning slot for inserting a prism, and the rotating base is provided with a locking component in the positioning slot for locking the prism.

[0010] By adopting the above technical solution, a positioning slot is opened on the rotating base for the prism to be inserted, which can achieve the initial positioning of the prism; a locking component is set in the positioning slot to lock the prism, which can prevent the prism from shaking or falling off during use, thus ensuring the stability and accuracy of the prism in the process of measuring building height.

[0011] Optionally, the locking component is a plunger spring, which includes a plunger housing, a plunger spring disposed within the plunger housing, and a plunger ball head connected to the plunger spring. The prism is provided with a locking groove that mates with the plunger ball head.

[0012] By adopting the above technical solution and using a plunger spring as a locking component, when the prism is inserted into the positioning slot, the plunger ball head is engaged in the locking groove of the prism under the action of the plunger spring, thereby achieving a firm lock on the prism, ensuring the stability of the prism during the measurement process, and thus improving the accuracy of the measurement.

[0013] Optionally, the locking component is a locking bolt, and the side wall of the rotating seat has a locking screw hole that communicates with the positioning slot and is used for arranging the locking bolt.

[0014] By adopting the above technical solution, the prism inserted into the positioning slot can be effectively locked by arranging the locking bolt in the locking screw hole. Compared with the locking method of spring plunger, the locking strength is more ideal.

[0015] Optionally, the locking component includes a first magnetic sheet and a second magnetic sheet, which are attracted to each other. The first magnetic sheet is disposed at the bottom of the prism, and the second magnetic sheet is disposed at the bottom wall of the positioning slot.

[0016] By adopting the above technical solution, another locking method for the prism and the rotating base is disclosed. A second magnetic plate is set on the bottom wall of the positioning slot of the rotating base and attracts the first magnetic plate at the bottom of the prism, which can achieve stable locking of the prism and make the prism more stable during the measurement process.

[0017] Optionally, the rotating base has at least two sets of positioning slots, and the two sets of positioning slots are circumferentially spaced along the axis of the rotating base.

[0018] By adopting the above technical solution, the rotating base has at least two sets of positioning slots spaced circumferentially along its axis, which can simultaneously install multiple prisms. During the measurement process, different prisms can be flexibly switched to improve measurement efficiency and reduce the time loss caused by changing prisms.

[0019] Optionally, it also includes an adjustment assembly for driving the rotating seat to rotate, the adjustment assembly including an adjustment frame disposed on the mounting frame and an adjustment drive component disposed on the adjustment frame.

[0020] By adopting the above technical solution, the adjustment component can drive the rotating seat to rotate, which can flexibly adjust the direction and angle of the prism, making it easy to accurately measure the height of buildings in different positions and under different conditions.

[0021] Optionally, the outer wall of the rotating seat is uniformly provided with driven gear rings, the mounting frame has an arc-shaped through hole corresponding to the driven gear ring, and the output shaft of the adjusting drive is provided with a drive gear that meshes with the driven gear ring.

[0022] By adopting the above technical solution, the driven gear ring on the outer wall of the rotating seat corresponds to the arc-shaped through hole of the mounting frame. The drive gear of the output shaft of the adjusting drive component meshes with the driven gear ring, so that the adjusting drive component can drive the rotating seat to rotate, which facilitates the adjustment of the prism position and angle.

[0023] Optionally, the mounting frame is provided with a rotating groove for mounting the rotating seat, the bottom of the rotating groove is provided with a rotating annular groove, and the bottom of the rotating seat is provided with rollers arranged in the rotating annular groove.

[0024] By adopting the above technical solution, the rotating groove is used for mounting the rotating seat, and the rotating ring groove cooperates with the circumferential rollers at the bottom of the rotating seat, making the rotating seat rotate more smoothly and flexibly, and improving the convenience of adjusting the prism angle when using the device.

[0025] Optionally, a laser rangefinder is also provided on the mounting frame, with the output end of the laser rangefinder pointing vertically downwards.

[0026] By adopting the above technical solution, the laser rangefinder sensor is set on the mounting frame with its output end pointing vertically downwards. This allows for the measurement of the distance from the building height measuring device to the ground, providing data reference for subsequent building height measurements and making the measurement process more accurate and efficient.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. Using drones to transport the main body and prisms avoids the need for manual placement of prisms, solving the problem of the cumbersome and high safety risks of manually placing prisms in areas such as bridge piers and cranes;

[0029] 2. The rotating base can be rotated, making it easy to adjust the position and angle of the prism and improving the accuracy of the measurement;

[0030] 3. The locking assembly can stably fix the prism on the rotating base, ensuring the stability of the prism during the measurement process. Attached Figure Description

[0040] Example 1:

[0041] Reference Figure 1 A building height measuring device includes a drone delivery body 1 and an installation assembly 2 disposed on the drone delivery body 1 for mounting a prism 6. The drone delivery body 1 has the same structure as drones in the prior art, therefore the specific structure and principle of the drone will not be described in this application.

[0042] Reference Figure 1 and Figure 2The mounting assembly 2 includes a mounting frame 21 and a rotating base 22. The mounting frame 21 includes two sets of connecting rods 211 fixed to the bottom of the UAV transport body 1 and a mounting plate 212 disposed at the other end of the connecting rods 211. The mounting plate 212 and the connecting rods 211 are fixedly connected by bolts or welding. The mounting plate 212 is generally circular, and its top has a rotating groove 213 for the rotating base 22 to be rotatably mounted.

[0043] Combination Figure 3 The mounting plate 212 has a rotating annular groove 2131 at the bottom of the rotating groove 213, and the rotating annular groove 2131 and the mounting plate 212 are coaxially arranged. In order to improve the smoothness of the rotation of the rotating seat 22, two sets of rollers 221 corresponding to the rotating groove 213 are fixedly installed at the bottom of the rotating seat 22. When the rotating seat 22 rotates, the rollers 221 can roll circumferentially along the rotating annular groove 2131.

[0044] The sidewalls of the rotating seat 22 are evenly provided with driven gear rings 222, and the sidewalls of the mounting plate 212 are provided with arc-shaped through holes 2121 corresponding to the driven gear rings 222. An adjustment assembly 3 for driving the rotating seat 22 is provided on the mounting frame 21. The adjustment assembly 3 includes an adjustment frame 31 fixed to the mounting plate 212 and an adjustment drive component 32 mounted on the adjustment frame 31. The adjustment drive component 32 is a drive motor, which is fixed to the adjustment frame 31 in an axially upward position. A drive gear 33 is fixed on the output shaft of the adjustment drive component 32, and the drive gear 33 passes through the arc-shaped through hole 2121 and meshes with the drive gear ring. In this embodiment, the activation of the adjustment drive component 32 is controlled by the control system of the UAV transport body 1, so the inspection personnel can remotely control the rotation of the adjustment drive component 32, thereby realizing the rotation of the rotating seat 22.

[0045] To further improve inspection efficiency, a laser rangefinder 4 is also installed on the UAV transport body 1. The emission point of the laser rangefinder 4 and the center point of the prism 6 are at the same height, and the output direction of the laser rangefinder 4 is vertically downward, so that the laser rangefinder 4 can measure the distance from the center point of the prism 6 to the reference surface at the bottom of the building. The inspectors observe the value of the laser rangefinder 4 through the telescope of the total station, and then input the height of the prism 6 into the total station.

[0048] The implementation principle of a building height measuring device in this application embodiment is as follows: the inspection personnel operate the drone transport body 1 to move the drone transport body 1 to one side of the building, and rotate the rotating seat 22 by adjusting component 3 so that the total station and prism 6 can correspond, and the height of prism 6 is detected by laser range sensor 4. Then, the telescope of the total station is adjusted, and after observing the top of the building, the overall height of the building is calculated.

[0052] In this embodiment, the locking component 5 is a locking bolt 52, and the outer side wall of the rotating seat 22 is provided with a locking screw hole 224 that communicates with the positioning slot 223. The locking screw hole 224 and the locking bolt 52 are threadedly engaged. After the prism 6 is inserted into the positioning slot 223, the locking bolt 52 is rotated so that the end of the locking bolt 52 abuts against the side wall of the prism 6 to achieve a locking effect.
