Description

Technical Field

[0001] This utility model belongs to the field of tunnel measurement device protection structure technology, specifically relating to a tunnel measurement laser reflector protection device. Background Technology

[0002] With rapid economic development, my country's infrastructure technology has undergone comprehensive upgrading and transformation, placing it among the world's top-tier infrastructure companies. Tunneling technology is a key component of this technology. Infrared laser measuring reflectors are required for tunnel measurements, but existing reflectors, due to their frequent operation within tunnels, are prone to bumps and knocks, which can severely damage them and affect the accuracy of tunnel measurements. Patent CN202221325174.1 proposes a protective device for an infrared laser measuring reflector used in tunnel measurements. This device utilizes a bracket, adjusting shaft, measuring head, support plate, positioning box, protective plate, miniature cylinder, pulley rod, inclined plate, insert rod, sliding rod, and top protective plate to protect the measuring head. While this patent meets certain usage requirements, practical application has revealed that the frame design for protection not only increases the load on the device but also increases wind resistance in strong winds, making it more prone to tipping over. Therefore, its practicality needs further improvement. Utility Model Content

Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a protective device for a tunnel measuring laser reflector, including a fixing frame 1 and a control box 7 connected thereto. The fixing frame 1 is made of U-shaped plastic material, and both ends of the fixing frame 1 are hollow. One end of the fixing frame 1 is embedded with a first protective airbag 4, and the other end of the fixing frame 1 is embedded with a second protective airbag 18. Both the first protective airbag 4 and the second protective airbag 18 are made of rubber. The fixing frame 1 is sleeved on the measuring body 6. A lens 5 is set on one side of the measuring body 6. The first protective airbag 4 is set on the same side as the lens 5. The control box 7 is set on the fixing frame 1. An tilt sensor 13 is fixedly connected inside the control box 7. The fixing frame 1 plays the role of fixed connection and stable support. Both the first protective airbag 4 and the second protective airbag 18 play a protective role. The control box 7 facilitates automatic control, and the tilt sensor 13 facilitates monitoring the tilt of the device.

[0022] The control box 7 has a power socket 10 on one side, and a ribbon cable 2 is connected to the power socket 10. The other end of the ribbon cable 2 is equipped with a USB plug 3. This design facilitates power supply to the device.

[0023] A heat dissipation window 11 is provided on the side of the control box 7 near the power socket 10. A storage battery 12 is provided on one side of the heat dissipation window 11. The storage battery 12 is fixedly connected to the control box 7. The heat dissipation window 11 facilitates heat dissipation inside the control box 7. The storage battery 12 supplies and stores electrical energy for the device.

[0024] The battery 12 is located on one side of the tilt sensor 13, and a high-pressure air pump 15 is located on the other side of the tilt sensor 13. A control board 14 is located on one side of the high-pressure air pump 15, which provides high-pressure gas to the device.

[0025] On the other side of the high-pressure air pump 15, there is an air tank box 16. Explosion-proof pipes 17 are provided at both ends of the air tank box 16. One explosion-proof pipe 17 is connected to the first protective airbag 4, and the other explosion-proof pipe 17 is connected to the second protective cylinder. The air tank box 16 facilitates the supply of high-pressure gas and the control of air flow interruption. The explosion-proof pipes 17 play the role of guiding flow and explosion prevention.

[0026] The control box 7 has a built-in display screen 8, and a control panel 9 is provided on one side of the display screen 8. The control panel 9 is fixedly connected to the control box 7. The display screen 8 facilitates the viewing of data, and the control panel 9 facilitates the operation of the device.

[0027] The first protective airbag 4 adopts a U-shaped plus semi-circular protective design, and the second protective airbag 18 adopts a U-shaped protective design. Through the above design, it is easy to provide good protection for the measuring body 6 and the lens 5.

[0028] The working principle of this utility model is as follows: Before use, the device is placed using the fixing bracket 1, with one side of the first protective airbag 4 and the lens 5 positioned on the same side. Then, the device is fitted onto the measuring body 6 at a suitable position and fixed. It is connected to the measuring body 6 via the USB plug 3, and the measuring body 6 provides power to the device. During use, after the measuring body 6 is supported and fixed, the device can be started via the control panel 9. The device parameters can be viewed on the display screen 8 and adjusted as needed. Once set, protection can be implemented. Because both the first protective airbag 4 and the second protective airbag 18 are folded and embedded in the cavity of the fixing bracket 1, the device has low wind resistance and is suitable for environments with high wind speeds, providing high safety. During protection, the high-pressure air pump 15 operates intermittently to maintain the high-pressure gas in the gas tank 16 within the set range. The tilt sensor 13 operates continuously. When the measuring body 6 tilts, the device will detect the tilt. The tilt sensor 13 transmits the detected data to the control box 7. The control box 7 analyzes and compares the data. When the tilt angle is greater than the set value, the gas tank 16 releases high-pressure gas. The high-pressure gas is delivered to the first protective airbag 4 and the second protective airbag 18 through the explosion-proof pipe 17, causing them to quickly inflate. When the measuring body 6 falls to the ground, the first protective airbag 4 and the second protective airbag 18 act as a buffer, preventing the measuring body 6 and the lens 5 from contacting and colliding with the ground, thus effectively protecting the measuring body 6 and the lens 5. This novel structure is reasonably designed and easy to install and use. Through the design of the fixing frame 1, the first protective airbag 4, and the second protective airbag 18, the volume of the protective airbags is greatly reduced, the wind resistance of the device is reduced, and the safety of the device is improved. Through the design of the first protective airbag 4 and the second protective airbag 18, the measuring body 6 and the lens 5 can be effectively protected, with good protection effect and strong practicality.
