Abstract
Description
Technical Field
[0001] This utility model relates to the field of belt flow and volume measurement technology, and in particular to a belt flow and volume measurement device based on solid-state lidar. Background Technology
[0002] In material conveying systems, belt conveyors are a common type of transmission equipment, widely used in mines, ports, factories, and other fields. To accurately measure the flow rate and volume of materials conveyed on the belt, traditional methods often employ weighing sensors or mechanical measuring devices. However, these methods often suffer from low accuracy, susceptibility to environmental influences, and high maintenance costs. Especially when conveying diverse materials and complex environmental conditions, the accuracy and reliability of traditional measurement methods are often difficult to guarantee. With the rapid development of lidar technology, solid-state lidar, due to its high precision, high stability, and strong anti-interference capabilities, has shown great potential in the field of material measurement.
[0003] However, when applying solid-state lidar to belt flow and volume measurement, the actual working environment of the belt conveyor must be considered, such as the impact of dust, mist, and high temperature on lidar performance. During the operation of the belt conveyor, friction occurs between the belt and the material, causing the temperature near the belt and idlers to rise. At the same time, dust and mist generated during material conveying can also interfere with lidar measurement. Most existing belt flow and volume measurement devices lack effective protection for lidar and have not adequately addressed the impact of high temperature, dust, and mist on measurement results.
[0004] Therefore, it is necessary to provide a new belt flow volume measurement device based on solid-state lidar to solve the above-mentioned technical problems. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0026] Please see Figures 1 to 6A belt flow volume measurement device based on solid-state lidar 5 is disclosed. The device comprises: a support 1, an idler roller 4, a solid-state lidar 5, an isolation box 6, a fixing structure 8, a cooling structure 9, and a flow-guiding fan 10. A drive pulley 2 is rotatably connected to one end of the top of the support 1, and a driven pulley 3 is rotatably connected to the other end of the top of the support 1. The drive pulley 2 and the driven pulley 3 are rotatably connected by a belt. An idler roller 4 is installed between the drive pulley 2 and the driven pulley 3, and the idler roller 4 is rotatably connected to the support 1. A solid-state lidar 5 is fixedly installed above the idler roller 4 at the top of the support 1. An isolation box 6 is fixedly installed at the top of the support 1. Multiple sets of filter plates 7 are slidably connected inside the isolation box 6. A fixing structure 8 is installed on one side of each filter plate 7. The fixing structure 8 includes a fixing plate 81 and a locking post 82. One end of each filter plate 7 is slidably connected to a fixed plate 81. A fixed plate 81 is symmetrically and slidably connected to locking posts 82 at both ends. A cooling structure 9 is installed inside the isolation box 6. The cooling structure 9 includes a flow guide plate 91, a cooling plate 92, and a cooling pipe 94. The flow guide plate 91 is fixedly connected to the bottom of the isolation box 6. Multiple sets of cooling plates 92 are equidistantly installed above the flow guide plate 91 inside the isolation box 6. Cooling pipes 94 are installed at the bottom of each set of cooling plates 92. A flow guide fan 10 is fixedly connected to the end of the isolation box 6 away from the filter plate 7. An air outlet filter 11 is fixedly connected to the end of the isolation box 6 near the flow guide fan 10. A first motor 12 is fixedly connected to the top of the bracket 1 near the drive pulley 2.

The output end of the second motor 13 is fixedly connected to the input shaft of the flow guide fan 10.
[0027] It should be noted that: the isolation box 6 has a measurement port located below the solid-state lidar 5, which allows the laser beam of the solid-state lidar 5 to irradiate the material being transported by the belt, and the solid-state lidar 5 to receive the reflected laser signal. The airflow fan 10 can make the airflow inside the isolation box flow in one direction.
[0028] Please see Figure 1 and Figure 6 The fixing structure 8 includes: a spring 83, a grip block 84, a rope 85, and a pulley 86.

[0029] It should be noted that the places where the pulley 86, the fixing plate 81, and the grip block 84 contact the rope 85 are all rounded, which can reduce the friction force on the rope 85 when sliding and increase the service life of the rope.
[0030] Please see Figure 1 and Figure 6 The isolation box 6 includes a drainage pipe 93, a cooling box 95, and a liquid storage tank 96.

The bottom of the support 1, located on one side of the cooling box 95, is fitted with a liquid storage tank 96. The bottoms of the drainage pipes 93 converge and insert into the liquid storage tank 96. The cooling plate 92 includes a first baffle 921, a second baffle 922, and a guide plate 923. The isolation box 6 is equidistantly fixed with drainage pipes 93. The enclosure is equipped with multiple sets of first baffles 921 and second baffles 922. A guide plate 923 is installed between the first baffles 921 and the second baffles 922. The two ends of the guide plate 923 are fixedly connected to the first baffles 921 and the second baffles 922, respectively.

Multiple sets of cooling plates 92 are arranged longitudinally inside the isolation box 6. The bottom of the first baffle 921 of the upper cooling plate 92 extends between the top of the first baffle 921 and the second baffle 922 of the lower cooling plate 92, together forming a V-shaped air chamber.
[0031] It should be noted that the drain pipe 93 has an opening on the side near the cooling plate 92 that corresponds to the cooling plate 92, so that the liquid on the surface of the guide plate 923 can flow into the drain pipe 93.
[0032] The working principle of the belt flow and volume measurement device based on solid-state lidar 5 provided by this utility model is as follows:
[0033] Measurement process: The first motor 12 is turned on, which drives the active pulley 2 to rotate. The active pulley 2 drives the driven pulley 3 and the idler roller 4 to rotate via a belt. The belt carries the material from left to right. When the material passes under the solid-state lidar 5, the solid-state lidar 5 emits a laser beam. The emitted laser beam shines on the target object, and part of the laser beam is reflected back by the target object. The reflected laser signal is received by the receiver of the solid-state lidar 5. The received reflected laser signal is converted into an electrical signal and then amplified, filtered, and digitized by the signal processor. The signal processor further analyzes these signals to extract useful information and measure the flow rate and volume of the material.
[0034] Filtration and Cooling: The second motor 13 is turned on, driving the airflow fan 10 to rotate. The airflow fan 10 drives the airflow from left to right. The airflow passes through the filter plate 7, where small particles such as dust are adsorbed. After passing through the filter plate 7, the airflow flows to the cooling plate 92 and through the V-shaped air chamber between the cooling plates 92. As the airflow passes through the cooling plate 92, the cooling tank 95 inputs coolant into the cooling pipe 94 through the inlet pipe. The coolant returns to the cooling tank 95 through the outlet pipe at one end of the cooling pipe 94. The cooling pipe 94 cools the cooling plate 92, reducing its temperature. The temperature of the airflow decreases as the airflow temperature drops, condensing the mist carried in the airflow into liquid. The liquid slides down the first baffle 921 and the second baffle 922 onto the guide plate 923. Because the two ends of the guide plate 923 are relatively low, the liquid flows along the guide plate 923 into the diversion pipe 93, and then into the liquid storage tank 96. Then, the cooled airflow passes through the working area of the solid-state lidar 5. The airflow ensures that the working environment temperature of the solid-state lidar 5 is constant and can cool components such as the idler roller 4. Finally, the airflow flows out of the isolation box 6 under the blowing of the diversion fan 10.
[0035] Quickly replace filter plate 7: Hold the fixed plate 81 with one hand and press the grip 84 into the fixed plate 81 with your fingers. The grip 84 will pull the rope 85 outward. The rope 85 will drive the locking pin 82 to squeeze the spring 83 and move it into the fixed plate 81. After removing the fixed plate 81, slide the filter plate 7 out of the fixed plate 81 and slide the clean filter plate 7 into the fixed plate 81. Then, press the grip 84 into the fixed plate 81 with your fingers and slide the fixed plate 81 into the isolation box 6. Release your hand. The spring 83 will push the locking pin 82 into the locking groove in the isolation box 6. The locking pin 82 will move outward and pull the rope 85, which will then pull the grip 84 back to its original position.
