[0039] Reference Figure 2 , Figure 3 and Figure 4 This utility model provides an embodiment of a non-contact wireless target ranging device, comprising a power supply box 1, a support plate 5 fixedly connected to the bottom left side of the power supply box 1, a groove 6 provided on the top right side of the support plate 5, a protective box 3 fixedly connected to the top of the support plate 5, a movable baffle 4 slidably connected to the left side inside the protective box 3, which can open or close the device by opening and closing the movable baffle 4, an energy block 7 fixedly connected to the top left side of the power supply box 1, a guide tube 8 fixedly connected to the left side of the energy block 7, which allows the laser to measure at a specified position, the bottom of the energy block 7 fixedly connected to the inside of the groove 6, a laser port 9 fixedly connected to the left side of the guide tube 8, a limit block 10 fixedly connected to the top of the support plate 5, a receiving tube 11 fixedly connected to the bottom left side of the energy block 7 for receiving the reflected laser for measurement, the left side of the receiving tube 11 extending through the outside of the limit block 10, and a heat dissipation mechanism 2 fixedly connected to the top of the power supply box 1.

[0040] Specifically, power supply box 1 provides stable power to the components. A support plate 5 is fixedly connected to the bottom left side of power supply box 1 for support. A groove 6 on the top right side of power supply box 1 is adapted to the bottom of energy block 7 for fixation. A protective box 2 3 is also fixedly connected to the top of support plate 5. A movable baffle 4 is slidably connected to the left side inside protective box 2 3. This baffle 4 can be opened or closed to open or close the device. When the device is idle or requires protection, closing the movable baffle 4 effectively prevents external dust, moisture, and harmful gases from damaging the internal components. Opening the movable baffle 4 during use ensures smooth measurement. The energy block is fixedly connected to the top left side of power supply box 1. 7 is the component for energy transmission and conversion of the device. The guide tube 8, which is fixedly connected to the left side of the energy block 7, guides the laser to measure at the designated position to ensure the accuracy and stability of the laser emission. The laser port 9 on the left side is the laser emission outlet. The limiting block 10 on the top of the support plate 5 cooperates with the receiving tube 11, which is fixedly connected to the bottom left side of the energy block 7. The receiving tube 11 is used to receive the reflected laser. It passes through the outside of the limiting block 10 to fix the position of the receiving tube 11, ensuring the accuracy of the measurement. The heat dissipation mechanism 2 on the top of the power supply box 1 can dissipate the heat generated by the device operation in time, avoid the high temperature from affecting the performance of the internal components, and ensure the long-term stable operation of the device.

[0041] Reference Figure 2 , Figure 3 and Figure 5 The heat dissipation mechanism 2 includes a connecting rod 201, a protective box 202 fixedly connected to the top of the connecting rod 201, a glass plate 203 fixedly connected to the front inside of the protective box 202, a fan 204 fixedly connected to the top inside of the protective box 202, and the fan 204 generates airflow to exchange heat with the outside.

The glass plate 203 on the front side of the protective box 202 is dustproof and waterproof without affecting the data observation of the staff, ensuring the visibility of the display instrument 207 while enhancing the protective effect. The fan 204 on the top inside generates strong wind through high-speed operation, accelerating airflow and heat exchange with the outside, quickly removing the heat generated during the operation of the device and reducing the internal temperature. The multiple heat dissipation slots 205 on the right side of the connecting rod 201, together with the heat dissipation fins 206 fixed in the slots, greatly expand the heat dissipation area, allowing heat to be dissipated more efficiently to the surrounding environment, effectively avoiding damage to the internal components of the device by high temperature, ensuring that the display instrument 207 can display data normally, and ensuring that the entire non-contact wireless target ranging device can maintain high accuracy and stability during long-term operation.

[0043] Reference Figure 1 , Figure 2 and Figure 3 Support legs 12 are fixedly connected to the bottom left front and rear ends of the support plate 5. Rubber bases 13 are fixedly connected to the bottom of the two support legs 12 to increase the friction with the contact surface. Support blocks 14 are fixedly connected to the bottom front and rear sides of the power box 1. Two brackets 15 are fixedly connected between the adjacent two support blocks 14. Mounting plate 16 is fixedly connected to the top of the protective box 3. Multiple solar panels 17 are fixedly connected inside the mounting plate 16.

[0044] Specifically, the support legs 12 at the front and rear ends of the left side of the bottom of the support plate 5, combined with the rubber base 13, increase the friction with the contact surface, effectively improving the stability of the device placement and avoiding errors caused by shaking during measurement. The support block 14 at the bottom of the power box 1 and the bracket 15 cooperate with each other to further strengthen the support strength of the bottom structure of the device, disperse the pressure generated during the operation of the equipment, and ensure the overall structure is stable. The multiple solar panels 17 fixed on the mounting plate 16 on the top of the protective box 3 can make full use of solar energy to convert it into electrical energy, providing clean energy supplement for the operation of the device. This not only reduces the dependence on traditional power sources, but also enhances the device's ability to work continuously in complex environments such as outdoors, achieving the dual benefits of energy saving and environmental protection.

[0045] Reference Figure 1 , Figure 2 and Figure 3 Two battery blocks 18 are fixedly connected to the top left side of the front of the power supply box 1. Power indicator lights 19 are fixedly connected to the front of each of the two battery blocks 18. The front and rear sides of the top of the protective box 202 are threaded with buckles 20 for fixing in a designated location. Two screws 21 are threaded to the left and right sides of the two buckles 20. The left and right sides of the top of the protective box 202 are fixedly connected with mounting boxes 22. Multiple desiccants 23 are fixedly connected inside the two mounting boxes 22 for dehumidification.

[0046] Specifically, the two battery blocks 18 on the top left of the front of the power supply box 1 provide power to the front power indicator light 19, which can display the power status in real time and intuitively, making it easy for staff to keep track of the power status. The buckle 20 on the top of the protective box 202 and the screw 21 can firmly fix the device in the designated position to prevent displacement during use and ensure measurement accuracy. The storage boxes 22 on the top left and right sides of the protective box 202 contain desiccants 23, which can effectively absorb moisture and prevent internal electronic components from being damaged by moisture. This creates a dry environment for the precision parts of the display instrument 207, improving the reliability and service life of the device.

[0047] Working principle: When this non-contact wireless target ranging device is working, the power supply box 1 provides stable power to the entire device. The support plate 5 supports the device and the energy block 7 is fixedly fixed by the top groove 6 and the adapter structure at the bottom of the energy block 7. Before the measurement begins, if the device is idle, the movable baffle 4 in the protective box 3 is closed to isolate external dust, water vapor and harmful gases and protect the internal components. When measurement is required, the movable baffle 4 is opened to create a path for laser emission and reception. The energy block 7 converts the power provided by the power supply box 1 into laser energy and guides the laser beam through the left guide tube 8. The laser beam is accurately emitted from the laser port 9 at the designated position. After the laser beam hits the target, it is reflected back. The limiting block 10 at the top of the support plate 5 and the receiving tube 11 at the bottom left of the energy block 7 work together. The receiving tube 11 passes through the outside of the limiting block 10 to accurately capture the reflected laser beam. Based on parameters such as the time difference between laser emission and reception, the internal signal processing system calculates the distance data to ensure that the device accurately completes the ranging work.

[0048] Furthermore, the connecting rod 201 securely connects the power supply box 1 and the protective box 202, providing a mounting carrier for the display instrument 207. The glass plate 203 on the front inside the protective box 202 can prevent dust and moisture from entering without affecting light transmission, ensuring that the staff can clearly observe the data of the display instrument 207. The fan 204 on the top inside runs after starting, accelerating heat exchange with the outside world and quickly removing the heat generated by the display instrument 207. The heat dissipation groove 205 and heat dissipation fins 206 on the right side of the connecting rod 201 increase the air circulation path and expand the heat dissipation area, effectively controlling the internal temperature of the device, avoiding high temperature damage to the component performance, ensuring that the display instrument 207 stably displays measurement data, and ensuring long-term high-precision operation of the non-contact wireless target ranging device.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
