Description

Technical Field

[0001] This invention belongs to the field of VR technology, specifically relating to a VR-based intelligent inspection device for construction sites. Background Technology

[0002] Construction sites require real-time monitoring of their operations. Some areas are narrow or dangerous, making on-site inspections unsuitable for workers. Currently, VR intelligent patrol vehicles are used for this purpose. These small vehicles are equipped with cameras and remote control modules, allowing operators to control the vehicle's operation and the VR cameras' rotation. The actual conditions of the construction site are then viewed remotely through a VR headset.

[0003] In the prior art, the invention patent with authorization announcement number CN213152219U discloses an industrial inspection device based on VR technology, including an intelligent vehicle, a first VR camera and a second VR camera. The intelligent vehicle has a cavity, and a cover plate is fixedly connected to the top of the cavity. A lifting mechanism is installed on the intelligent vehicle. The lifting mechanism includes a first servo motor, a threaded rod and a threaded tube. The first servo motor is installed in the inner cavity of the intelligent vehicle. The output shaft of the first servo motor is fixedly connected to the threaded rod. The threaded tube is threaded to the threaded rod and extends to the top of the cover plate. The cross-section of the threaded tube is hexagonal. A hexagonal through hole adapted to the threaded tube is opened on the cover plate. The top of the threaded tube is movably connected to a support plate via a bearing. A second servo motor is fixedly connected to the top of the support plate. The output shaft of the second servo motor is fixedly connected to a rotary table. A third servo motor is fixedly connected to the right side of the rotary table. The output shaft of the third servo motor is fixedly connected to a first rotating shaft. The first VR camera is fixedly connected to the first rotating shaft. A fourth servo motor is fixedly connected to the left side of the rotary table. The output shaft of the fourth servo motor is fixedly connected to a second rotating shaft. The second VR camera is fixedly connected to the second rotating shaft. Construction sites have complex terrain. Cameras can be used to observe the terrain and choose the best route. However, it is unavoidable to pass through slopes or pits during the journey. Because the VR intelligent cruise vehicle itself is small and carries a camera, control motherboard, and remote control antenna, its stability is poor, and it may overturn. If it overturns on a construction site, the VR camera and control motherboard on the VR intelligent cruise vehicle are easily damaged. Furthermore, the VR intelligent cruise vehicle is far from people, making it inconvenient to handle. Summary of the Invention

[0004] The purpose of this invention is to provide a VR-based intelligent inspection device for construction sites, which can remotely monitor the conditions of construction sites and ensure stable vehicle operation.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] The VR-based intelligent inspection device for construction sites includes a vehicle body, a VR camera mounted on the vehicle body, a control motherboard, and an antenna for signal transmission. The vehicle body includes a base and a top cover. A counterweight is suspended on the top cover, and a counterweight is installed on the counterweight. A support leg is provided at the end opposite the counterweight to support the vehicle body and reduce its tilt. The counterweight and the support leg are connected by a connecting arm, which is located at both ends of the connecting arm. The connecting arm is driven by a counterweight motor to rotate in a ring to adjust the center of gravity of the vehicle body. A pointer for determining the downward tilt direction of the vehicle body and a pointer angle detector for detecting the pointer angle are installed on the vehicle body. The angle of rotation of the support leg is consistent with the angle of rotation of the pointer. The counterweight is disc-shaped, and the base has a through hole that mates with the counterweight. An annular through groove is formed between the counterweight and the base to allow the support leg to pass through the base and extend to the ground below the base. The VR camera, antenna, counterweight motor, pointer angle detector, and control motherboard are connected.

[0007] Furthermore, the support leg is connected to a support leg motor that drives the support leg to extend and retract. The lower part of the support leg is a caster wheel structure. The caster wheel structure includes a guide leg that moves up and down with the upper part of the support leg and an arc-shaped support base connected to the support leg. Multiple casters arranged along the arc are installed on the arc-shaped support base.

[0008] Furthermore, the guide leg is connected to a shock-absorbing spring to reduce the impact force between the caster wheel and the ground.

[0009] Furthermore, the wheels of the vehicle body are tracked wheels, which are located on both sides of the vehicle body to adapt the vehicle body to bumpy road sections.

[0010] Furthermore, the counterweight is supported by a base and is teardrop-shaped, with the weight gradually increasing from the center of the counterweight base outwards.

[0011] Furthermore, the center of the counterweight is installed at the center of the base to improve the stability of the vehicle body.

[0012] Furthermore, the base and the counterweight are provided with sealing rings that mate with the annular groove to improve the sealing of the bottom of the vehicle body and prevent dust from entering the vehicle body.

[0013] Furthermore, a camera base is installed at the lower part of the VR camera to drive the VR camera to rotate. The camera base includes a first rotating component that drives the VR camera to rotate 360° on a first plane and a component that drives the VR camera to rotate 360° on a second plane. The first plane is perpendicular to the second plane.

[0014] Furthermore, the first rotating assembly includes a first bracket and a first motor that drives the first bracket to rotate, the first motor being mounted on the upper cover; the second rotating assembly includes a second bracket and a second motor that drives the second bracket to rotate, the second motor being mounted on the first bracket, and the VR camera being mounted on the second bracket.

[0015] Furthermore, the pointer is rotatably connected to the vehicle body via a pointer base, and indicates the tilt angle of the vehicle body in real time under the action of gravity. The pointer angle detector monitors the rotation angle of the pointer in real time and transmits the data to the control motherboard so that the control motherboard controls the counterweight motor to drive the support leg to rotate to the same angle as the pointer, and the counterweight is located at a position 180° relative to the support leg.

[0016] The beneficial effects of this invention are:

[0017] The VR-based intelligent inspection device for construction sites of this invention can remotely monitor the construction site through a VR camera, VR headset, and antenna control signal transmission, while maintaining stable vehicle operation. A pointer indicates the vehicle's tilt in real time, and the mainboard controls the position of the counterweight and outriggers, ensuring the counterweight is positioned on the upper side of the tilt and the outriggers on the lower side to support the vehicle, reducing the degree of tilt and maintaining stability.

Detailed Implementation

[0023] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0024] Example 1

[0025] This embodiment of the VR-based intelligent inspection device for construction sites includes a vehicle body 100, a VR camera 110 mounted on the vehicle body, a control motherboard 120, and an antenna 130 for signal transmission. The VR camera, antenna, and control motherboard are connected. The control motherboard, VR camera, and antenna for signal transmission are existing technologies. Signal transmission utilizes a GSM network to transmit control commands issued by the remote control terminal. The GSM network can achieve nationwide or even global coverage, allowing users to observe scenes thousands of miles away through a VR headset and control the operation of the vehicle body and VR camera thousands of miles away. The VR camera rotates up, down, left, and right along with the VR headset, meaning the VR camera and VR headset operate synchronously.

[0026] The vehicle body includes a base 200 and a top cover 300, which are fixedly connected by bolts. A counterweight base 400, which is disc-shaped, is suspended from the top cover 300 by a boom 310. The upper end of the boom 310 is fixedly connected to the top cover, and the lower end is fixedly connected to the counterweight base 400. A counterweight 410 is mounted on the counterweight base 400. A support leg 500 is provided at the opposite end of the counterweight to support the vehicle body and reduce its tilt. The counterweight and the support leg are connected by a connecting arm 420, which is fixedly connected to both ends of the connecting arm. The connecting arm is driven to rotate in a ring by a counterweight motor (not shown in the figure) to adjust the center of gravity of the vehicle body. The counterweight 410 is supported by the base 200 and is teardrop-shaped. The weight of the counterweight 410 gradually increases from the center of the counterweight base outwards to increase the force of the counterweight. The center of the counterweight disc 400 is installed at the center of the base to improve the stability of the vehicle body.

[0027] A foot motor 520 is connected to the outrigger 500 to drive its extension and retraction. The outrigger motor is connected to the control board. When the vehicle body tilts, the outrigger motor controls the outrigger to move downwards, bringing the vehicle body to a more balanced state. The lower part of the outrigger 500 is a caster structure 510, which includes a guide leg 511 that moves vertically along the upper part of the outrigger, and an arc-shaped support base 512 connected to the guide leg. Multiple casters 513 arranged along the arc shape are mounted on the arc-shaped support base 512. The outrigger motor is connected to the guide leg to drive its vertical movement. A shock-absorbing spring is connected to the guide leg 511 to reduce the impact force between the casters and the ground. The arc-shaped support base 512 and the multiple casters 513 work together to increase the support area and improve the stability of the vehicle body.

[0028] The vehicle body 100 is equipped with a pointer 140 for determining the downward tilt direction of the vehicle body and a pointer angle detector 150 for detecting the pointer angle. The angle of rotation of the support leg is consistent with the angle of rotation of the pointer. The pointer angle detector 150 is connected to the control main board. The pointer is rotatably connected to the vehicle body through a pointer base, and indicates the tilt angle of the vehicle body in real time under the action of gravity. The pointer angle detector monitors the rotation angle of the pointer in real time and transmits the data to the control main board so that the control main board controls the counterweight motor to drive the support leg to rotate to the same angle as the pointer, and the counterweight is located at a position 180° opposite to the support leg.

[0029] The base 200 has a through hole that mates with a counterweight seat, which is located within the through hole. The diameter of the through hole is larger than the diameter of the counterweight seat. An annular groove 210 is formed between the counterweight seat 400 and the base 200 to allow the support leg to move in a circular motion, thus allowing the support leg to pass through the base and extend to the ground below. The shape of the arc-shaped support seat is adapted to the annular groove, allowing the arc-shaped support seat to move in an arc shape as the guide leg rotates. A sealing ring (shown in the figure) is provided on the base and the counterweight seat to mate with the annular groove 210, improving the sealing of the vehicle body bottom and preventing dust from entering the vehicle body.

[0030] The VR camera 110 has a camera base 600 mounted on its lower part, which drives the VR camera to rotate. The camera base 600 includes a first rotating assembly that drives the VR camera to rotate 360° on a first plane and a second rotating assembly that drives the VR camera to rotate 360° on a second plane, the first plane being perpendicular to the second plane. The first rotating assembly includes a first bracket 610 and a first motor 620 that drives the first bracket to rotate, the first motor 620 being mounted on the upper cover 300. The second rotating assembly includes a second bracket 630 and a second motor 640 that drives the second bracket to rotate, the second motor being mounted on the first bracket, and the VR camera being mounted on the second bracket.

[0031] The vehicle body has tracked wheels 700, which are located on both sides of the vehicle body to adapt to bumpy roads. A power supply 320 is installed on the top cover 300.

[0032] This invention relates to a VR-based intelligent inspection device for construction sites. Operators can view the surrounding construction conditions and road conditions through a VR camera and choose a relatively flat road surface to drive on. However, construction site conditions are complex, and slopes or pits are unavoidable. A pointer can indicate the vehicle's tilt direction in real time under gravity, such as tilting forward or to the left. After the pointer indicates the tilt direction, a pointer angle detector detects the tilt angle and sends the data to the control board. The control board then controls the counterweight motor to rotate, causing the side of the support arm connected to the outriggers to align with the pointer angle. The counterweight is positioned 180° relative to the outriggers, pressing the vehicle downwards to improve stability. The outriggers, driven by outrigger motors, extend downwards, pressing the vehicle to a more level position as much as possible. The outriggers then press the vehicle upwards to improve stability and prevent tipping.
