Through data fusion algorithms, it combines the advantages of each sensor, eliminates measurement errors and uncertainties of a single sensor, and improves the accuracy and reliability of level measurement. It is suitable for level monitoring in large-scale warehousing facilities in complex industrial environments, ensuring the accuracy of inventory data.
[0003] Existing level gauges have relatively simple measurement methods, and there is room for improvement in terms of multi-path measurement, measurement data accuracy, flexible adjustment of measurement angle, and scope of application. Utility Model Content
[0004] The purpose of this invention is to provide a material level measurement device that integrates millimeter-wave radar and laser rangefinder, enabling multi-path measurement operations to ensure measurement accuracy. It also allows for flexible adjustment of the measurement angle, has high efficiency adaptability to different production locations, and is highly practical.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A level measuring device integrating millimeter-wave radar and laser rangefinder includes a flange seat. A rotary connection hole is provided on the outer surface of the flange seat, and a ball seat is rotatably connected inside the rotary connection hole. A mounting hole is provided at the central axis position of the ball seat, and a millimeter-wave radar level gauge is fixedly installed inside the mounting hole. A movable through groove is provided on the outer surface of the flange seat, and a movable seat is rotatably installed inside the movable through groove. A mounting groove is provided on the outer surface of the movable seat, and a laser rangefinder is fixedly installed inside the mounting groove.
[0007] By adopting the above technical solution, millimeter-wave radar level gauges and laser rangefinders can be used to perform level measurement operations simultaneously, improving measurement accuracy. At the same time, the measurement angle can be flexibly adjusted to adapt to complex working environments.
[0008] Furthermore, an adjusting disc is rotatably mounted on the outer surface of the flange seat, and two adjusting slots are provided on the outer surface of the adjusting disc. Two locking screws are fixedly connected to the upper surface of the flange seat, and the two locking screws pass through the interior of the two adjusting slots respectively. A locking nut is threaded onto one end of each locking screw.
[0009] By adopting the above technical solution, the millimeter-wave radar level gauge can be adjusted in a planar dimension by rotating the adjustment disc.
[0010] Furthermore, the millimeter-wave radar level gauge is fitted with a connecting bracket, and a rotating connector is fixedly connected to both the side surface of the connecting bracket and the upper surface of the adjusting plate. A screw is fixedly connected to the end face of one of the rotating connectors, and a screw sleeve is rotatably connected to the end face of the other rotating connector. One end of the screw is threaded into the threaded hole of the screw sleeve.
[0011] By adopting the above technical solution, the millimeter-wave radar level gauge can be adjusted in one dimension by utilizing the limiting cooperation between the screw sleeve and the screw.
[0012] Furthermore, the outer cover of the ball seat is fitted with two symmetrically distributed first locking blocks, which are fixedly mounted on the flange seat by bolts.
[0013] By adopting the above technical solution, the ball seat can be limited to ensure stable rotation.
[0014] Furthermore, the outer cover of the movable seat is fitted with two opposing second locking blocks, which are bolted to the flange seat.
[0015] By adopting the above technical solution, the movable seat can be limited to ensure stable rotation.
[0016] Furthermore, a fixing block is fixedly connected to the outer surface of the second locking block, and a threaded hole is provided on the outer surface of the fixing block, and a limit bolt is installed in the internal thread of the threaded hole.
[0017] By adopting the above technical solution, the movable seat can be effectively limited and locked.
[0018] In summary, the beneficial technical effects of this utility model are as follows:
[0019] 1. This utility model is movably installed on the flange seat via a ball seat and a movable seat. After installation, the detection orientation of the millimeter-wave radar level gauge and the laser rangefinder can be adjusted. Since the millimeter-wave radar level gauge and the laser rangefinder can be adjusted independently, they can flexibly meet different usage requirements, and the overall applicability is effectively improved. At the same time, different level measurement methods can be selected according to different measured objects. When both are suitable, the two measurement data can be used for mutual self-checking to improve measurement accuracy.
[0020] 2. This utility model allows for the adjustment of the millimeter-wave radar level gauge by twisting the screw sleeve. Since the screw is threaded inside the screw sleeve, the rotation of the screw sleeve can effectively adjust the distance between the two rotating connecting parts, thereby enabling the millimeter-wave radar level gauge to perform angle adjustment on the longitudinal plane. Then, the adjustment disc can be rotated. Since the locking screw is fixedly connected to the flange seat and passes through the adjustment groove, rotating the adjustment disc can adjust the angle of the millimeter-wave radar level gauge on the plane. After adjustment, tightening the locking nut allows for a limit operation on the millimeter-wave radar level gauge after angle adjustment. The entire adjustment operation is flexible, convenient, and highly practical.
[0021] 3. This utility model allows the movable seat to be rotated directly when adjusting the angle of the laser rangefinder. This enables the laser rangefinder to rotate around the central axis of the movable seat. After adjustment, tightening the limiting bolt will cause one end of the limiting bolt to press against the end face of the movable seat, effectively limiting the movement of the movable seat and ensuring stable operation of the laser rangefinder, thus further improving its practicality.

[0025] The method of this utility model will be further described in detail below with reference to the accompanying drawings.
[0026] Reference Figure 1 , Figure 2A level measuring device integrating millimeter-wave radar and laser rangefinder includes a flange seat 1. A rotary connection hole is provided on the outer surface of the flange seat 1, and a ball seat 2 is rotatably connected inside the rotary connection hole. A mounting hole is provided at the central axis position of the ball seat 2, and a millimeter-wave radar level gauge 13 is fixedly installed inside the mounting hole. A movable through groove is provided on the outer surface of the flange seat 1, and a movable seat 12 is rotatably installed inside the movable through groove. A mounting groove is provided on the outer surface of the movable seat 12, and a laser rangefinder 14 is fixedly installed inside the mounting groove. Two symmetrically distributed first locking blocks 3 are fastened to the outer cover of the ball seat 2. The first locking blocks 3 are fixedly installed on the flange seat 1 by bolts. The outer cover of the movable seat 12 is fastened with two opposing second locking blocks 15. The second locking blocks 15 are bolted to the flange seat 1, and are movably mounted on the flange seat 1 via the ball seat 2 and the movable seat 12. After installation, the detection orientation of the millimeter-wave radar level gauge 13 and the laser rangefinder 14 can be adjusted. Since the millimeter-wave radar level gauge 13 and the laser rangefinder 14 can be adjusted independently, they can flexibly meet different usage requirements, and the overall applicability is effectively improved. At the same time, different level measurement methods can be selected according to different measured objects. When both are suitable, the two measurement data can be used for mutual self-checking to improve measurement accuracy.
[0027] Reference Figure 1 An adjusting disc 8 is rotatably mounted on the outer surface of the flange seat 1. Two adjusting slots 11 are provided on the outer surface of the adjusting disc 8. Two locking screws 9 are fixedly connected to the upper surface of the flange seat 1, passing through the two adjusting slots 11 respectively. A locking nut 10 is threaded onto one end of each locking screw 9. A connecting bracket 4 is fitted onto the millimeter-wave radar level gauge 13. A rotating connector 5 is fixedly connected to the side surface of the connecting bracket 4 and the upper surface of the adjusting disc 8. A screw 6 is fixedly connected to the end face of one rotating connector 5, and a screw sleeve 7 is rotatably connected to the end face of the other rotating connector 5. One end of the screw 6 is threaded into the threaded hole of the screw sleeve 7. When adjusting the millimeter-wave radar level gauge 13, the screw sleeve 7 can be twisted. Since the screw 6 is threaded inside the screw sleeve 7, the rotation of the screw sleeve 7 can effectively adjust the distance between the two rotating connecting parts 5, thereby enabling the millimeter-wave radar level gauge 13 to perform angle adjustment on the longitudinal plane. Then, the adjustment disc 8 can be rotated. Since the locking screw 9 is fixedly connected to the flange seat 1 and passes through the adjustment groove 11, rotating the adjustment disc 8 can perform angle adjustment on the plane of the millimeter-wave radar level gauge 13. After the adjustment is completed, the locking nut 10 is tightened. At this time, the millimeter-wave radar level gauge 13 with the angle adjusted can be limited. The whole adjustment operation is flexible, convenient and practical.
[0028] Reference Figure 1A fixing block is fixedly connected to the outer surface of the second locking block 15, and a threaded hole is provided on the outer surface of the fixing block. A limit bolt 16 is installed in the internal thread of the threaded hole. When adjusting the angle of the laser rangefinder 14, the movable seat 12 can be directly rotated. At this time, the laser rangefinder 14 can rotate around the rotation axis of the movable seat 12. After the adjustment is completed, the limit bolt 16 is tightened. At this time, one end of the limit bolt 16 is pressed against the end face of the movable seat 12, which can effectively limit the movable seat 12, thereby ensuring the stable operation of the laser rangefinder 14 and further improving its practicality.
[0029] Working principle: In use, first install the device at the designated location. After installation, adjust the detection angles of the millimeter-wave radar level gauge 13 and the laser rangefinder 14. When adjusting the millimeter-wave radar level gauge 13, twist the screw sleeve 7. Since the screw 6 is threaded inside the screw sleeve 7, the rotation of the screw sleeve 7 effectively adjusts the distance between the two rotating connecting parts 5, thereby enabling the millimeter-wave radar level gauge 13 to perform angle adjustment on the longitudinal plane. Next, rotate the adjusting disc 8. Since the locking screw 9 is fixedly connected to the flange seat 1 and passes through the adjusting groove 11, rotating the adjusting disc 8 allows for angle adjustment on the plane of the millimeter-wave radar level gauge 13. After adjustment... Tighten the locking nut 10. At this time, the millimeter-wave radar level gauge 13, whose angle has been adjusted, can be limited. When adjusting the angle of the laser rangefinder 14, directly rotate the movable seat 12. This allows the laser rangefinder 14 to rotate around the central axis of the movable seat 12. After adjustment, tighten the limiting bolt 16. At this time, one end of the limiting bolt 16 presses against the end face of the movable seat 12, which can effectively limit the movable seat 12 and ensure the stable operation of the laser rangefinder 14. After adjustment, the corresponding measurement method and structure can be selected according to the object being measured. When both are suitable, the two measurement data can be used for mutual self-checking to improve measurement accuracy.

Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
