Description

Technical Field

[0001] This utility model relates to the field of dust detection technology, specifically a dust radar detection device. Background Technology

[0002] In port operations, bulk coal storage yards are crucial operational areas, mostly using open-air storage. However, most companies lack coal dust monitoring facilities, and for a long time, real-time dust particulate matter monitoring equipment for large-area open-air coal storage yards has been largely unused. This lack of real-time, scientific monitoring data has led to excessive reliance on manual experience in environmental management of port open-air storage yards, resulting in imprecise management methods and unsatisfactory environmental effects. Therefore, developing dust detection devices suitable for port open-air storage yards has become an urgent problem for the industry. Currently, dust concentration measurement equipment is mainly divided into two categories: sampling methods and non-sampling methods. Sampling methods rely on samplers to collect dust samples and obtain concentration values ​​through weighing and calculation. Although they can provide relatively accurate results, the operation process is cumbersome and time-consuming, which cannot meet the needs of real-time monitoring. Light scattering or light absorption technology in non-sampling methods can quickly obtain dust concentration data. Among them, light scattering method achieves rapid measurement of dust mass concentration by capturing the intensity of the scattered light signal signal after particles are irradiated. Radar detectors based on this principle have become an important development direction in the field of dust detection due to their non-contact and fast response characteristics. While radar detection technology has certain advantages, existing radar detection devices on the market generally have limitations. Most of these devices are fixedly installed, resulting in a severely limited detection range, covering only a single direction or a small area. This makes it difficult to comprehensively detect large areas with complex spatial structures, such as port open-air storage yards. Because it is impossible to obtain information on the dust distribution throughout the storage yard, the collected dust detection data lacks representativeness and completeness, seriously affecting the accuracy of the data and failing to provide a reliable basis for port environmental protection decisions and dust control.

[0003] Therefore, we propose a dust radar detection device to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide a dust radar detection device to solve the problems mentioned in the background art, such as the lack of effective dust monitoring equipment in open coal storage yards at ports, the cumbersome operation of existing dust detection devices that cannot monitor in real time, and the limited detection range of radar detection devices leading to inaccurate data.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust radar detection device, comprising a toothed plate and a mounting frame, wherein an adjustment component is installed on the side wall of the toothed plate, and a notch is provided inside the toothed plate; a support column is fixedly connected to the mounting frame, and a limit wheel is rotatably connected to the outer ring of the support column; a rotating column is rotatably connected to the mounting frame; a rotating component is provided on the mounting frame, and the rotating component includes a dual-axis motor fixedly connected to the mounting frame, the lower output end of the dual-axis motor being fixedly connected to the rotating column; a turntable is fixedly connected to the bottom of the rotating column, and a fixed seat is fixedly connected to the bottom surface of the turntable; a rotating shaft is rotatably connected inside the fixed seat, and a mounting seat is rotatably sleeved on the rotating shaft; a radar detector is fixedly mounted on the mounting seat.

[0006] Preferably, the adjustment component includes a fixing block fixedly connected to the toothed plate, an electric push rod fixedly connected in the middle of the fixing block, a slider fixedly connected to the output end of the electric push rod, a spiral frame fixedly connected to the bottom surface of the toothed plate, and a spiral groove formed inside the spiral frame.

[0007] Preferably, a toothed plate is fixedly connected to the side wall of the slider, and the slider is slidably connected to the groove.

[0008] Preferably, a distance sensor is fixed to the side wall of the toothed plate, and the distance sensor is electrically connected to the electric actuator.

[0009] Preferably, the upper output end of the dual-axis motor is fixedly connected to a drive shaft, and a drive gear is fixedly connected to the drive shaft, the drive gear meshing with the gear plate.

[0010] Preferably, an arc-shaped half-gear is fixed to the side wall of the mounting base, and the arc-shaped half-gear meshes with the toothed plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model achieves omnidirectional coverage detection through the coordinated movement of multiple components. A dual-axis motor drives a rotating column, which in turn rotates a turntable, causing the radar detector to perform circular motion and achieve preliminary detection in different directions. The meshing of the transmission gear with the first gear plate moves the mounting bracket, allowing the radar detector to cover different horizontal positions. The meshing of the arc-shaped half-gear with the second gear plate enables the radar detector to perform detection at different angles. The three components work together to allow the radar detector to achieve 360-degree rotation detection in the horizontal direction, and to expand the detection range in the vertical direction through angle adjustment, avoiding blind spots. It can perform omnidirectional, blind-spot-free detection of the entire detection area, improving the comprehensiveness of detection compared to traditional detection devices.

[0012] 2. This invention uses a distance sensor to monitor the distance between the radar detector and the target object in real time. When the detected distance reaches a preset threshold, such as when the arc-shaped half-gear is about to contact the second toothed plate, it can quickly transmit a signal to the electric actuator control system. The electric actuator automatically adjusts its extension and retraction length according to a preset program, driving the second toothed plate to move. Through meshing with the arc-shaped half-gear, it precisely adjusts the detection angle of the radar detector. This intelligent adjustment requires no manual intervention and can automatically optimize the detection angle according to the actual detection environment, improving detection efficiency and making the device more adaptable to complex and changing detection scenarios.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1: Please refer to Figures 1-5A dust radar detection device includes a toothed plate 1 and a mounting frame 4. The toothed plate 1 has a notch 3. A support column 5 is fixedly connected to the mounting frame 4. A limit wheel 6 is rotatably connected to the outer ring of the support column 5. The limit wheel 6 is slidably connected to the notch 3. The notch 3 can adapt to the structure of the limit wheel 6, providing a stable movement track for the limit wheel 6 and ensuring that the limit wheel 6 rolls smoothly in it. It not only plays a supporting and guiding role, but also effectively restricts the movement direction of the mounting frame 4, ensuring that the mounting frame 4 moves smoothly on the predetermined trajectory.

[0017] A rotating column 7 is rotatably connected to the mounting frame 4. A rotating assembly 70 is mounted on the mounting frame 4. The rotating assembly 70 includes a dual-axis motor 71 fixedly connected to the mounting frame 4. The lower output end of the dual-axis motor 71 is fixedly connected to the rotating column 7. A drive shaft 72 is fixedly connected to the upper output end of the dual-axis motor 71. A drive gear 73 is fixedly connected to the drive shaft 72, and the drive gear 73 meshes with a gear plate 1. A turntable 8 is fixedly connected to the bottom of the rotating column 7. A fixed seat 9 is fixedly connected to the bottom surface of the turntable 8. A rotating shaft 10 is rotatably connected inside the fixed seat 9. A mounting base 11 is rotatably sleeved on the rotating shaft 10. A radar detector 12 is fixedly mounted on the mounting base 11. The radar detector 12 is the core component for dust detection. It uses advanced radar detection technology and can detect information such as dust concentration, distribution, and movement status by emitting and receiving electromagnetic wave signals. The radar detector 12 features high precision and high sensitivity, enabling accurate detection of dust data in complex industrial or outdoor environments. The radar detector 12 is securely connected to the mounting base 11 by bolts or other fixing methods to ensure that it will not loosen or shift during operation, thus guaranteeing the accuracy and stability of the detection data. An arc-shaped half-gear 110 is fixed to the side wall of the mounting base 11. The arc-shaped half-gear 110 meshes with the toothed plate 26. Through the meshing of the arc-shaped half-gear 110 and the toothed plate 26, the mounting base 11 and the radar detector 12 can rotate within a certain angle range, thereby expanding the detection range of the radar detector 12.

[0018] Specifically, when the dual-axis motor 71 is started, the lower output end of the dual-axis motor 71 drives the rotating column 7 to rotate, and the rotating column 7 in turn drives the turntable 8 fixedly connected to its bottom to rotate. Since the bottom surface of the turntable 8 is fixedly connected to the fixed seat 9, and the rotating shaft 10 is rotatably connected inside the fixed seat 9, and the mounting seat 11 is rotatably sleeved on the rotating shaft 10, and the radar detector 12 is installed on the mounting seat 11, the rotation of the turntable 8 will drive the entire radar detector 12 to perform circular motion around the axis of the rotating column 7, so as to achieve preliminary detection in different directions. At the same time, the upper output end of the dual-axis motor 71 drives the transmission shaft 72 to rotate. The transmission gear 73 on the transmission shaft 72 meshes with the toothed plate 1. As the transmission gear 73 rotates, under the action of the toothed plate 1, the transmission gear 73 will drive the mounting frame 4 to move along the direction of the toothed plate 1. Since the limiting wheel 6 connected to the outer ring of the support column 5 rolls in the recess 3 of the toothed plate 1, the movement of the mounting frame 4 is more stable, and the direction of movement is limited by the limiting wheel 6, ensuring that the mounting frame 4 can move along the predetermined trajectory. The movement of the mounting frame 4 enables the radar detector 12 to perform detection at different positions, further expanding the detection range. In addition, during the movement of the mounting frame 4, the arc-shaped half gear 110 on the side wall of the mounting base 11 meshes with the toothed plate 26. As the mounting frame 4 moves, the arc-shaped half gear 110 rotates under the action of the toothed plate 26, thereby driving the mounting base 11 and the radar detector 12 to rotate around the rotating shaft 10 at a certain angle. Through the meshing transmission between the arc-shaped half gear 110 and the toothed plate 26, the radar detector 12 can perform detection at different angles, achieving all-round coverage of the detection area and greatly improving the accuracy and comprehensiveness of dust detection. Throughout the operation, the radar detector 12 continuously emits electromagnetic wave signals. When these signals encounter dust, they are reflected. The radar detector 12 receives the reflected signals and transmits them to its internal signal processing system. The signal processing system filters, amplifies, analyzes, and demodulates the received signals, and uses specific algorithms to calculate information such as dust concentration, distribution, and movement, thereby achieving effective dust detection.

[0019] Example 2: This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 1-5 An adjustment assembly 2 is installed on the side wall of toothed plate 1. The adjustment assembly 2 includes a fixing block 21 fixedly connected to toothed plate 1, an electric push rod 22 fixedly connected in the middle of the fixing block 21, and a slider 23 fixedly connected to the output end of the electric push rod 22. A ring frame 24 is fixedly connected to the bottom surface of toothed plate 1, and a ring groove 25 is opened in the ring frame 24. A toothed plate 26 is fixedly connected to the side wall of the slider 23, and the slider 23 is slidably connected to the ring groove 25. A distance sensor 27 is fixed to the side wall of toothed plate 1. The distance sensor 27 can detect radar detection in real time and accurately. The distance between the detector 12 and the target object within the detection area is measured by the distance sensor 27, which is electrically connected to the electric actuator 22. The distance sensor 27 and the electric actuator 22 transmit the detected distance signal to the control system of the electric actuator 22 in real time. The electric actuator 22 automatically adjusts the extension length of the actuator according to the preset program and distance threshold, thereby controlling the position of the toothed plate 26 and realizing intelligent adjustment of the detection angle of the radar detector 12. The arc-shaped half gear 110 is made of high-strength metal material and has good wear resistance and transmission performance.

[0020] Specifically, during the operation of the dust radar detection device, the distance sensor 27 always maintains a real-time monitoring state, accurately capturing the distance data between the radar detector 12 and the target object in the detection area. When the mounting frame 4 drives the radar detector 12 to move and detect under the meshing drive of the transmission gear 73 and the toothed plate 1, and the arc-shaped half gear 110 gradually approaches the toothed plate 26, if the distance value detected by the distance sensor 27 touches the preset threshold at this time, it will immediately convert the distance signal into an electrical signal and quickly transmit it to the control system of the electric push rod 22. After receiving the signal from the distance sensor 27, the electric actuator 22 immediately begins analysis and processing according to the preset program. When the detection angle of the radar detector 12 needs to be adjusted after a round trip, the electric actuator 22 will start quickly. Through the internal precision transmission mechanism, the rotational motion of the motor is converted into linear thrust, which pushes the slider 23 to slide smoothly in the loop groove 25. Since the slider 23 is firmly connected to the toothed plate 26, the movement of the slider 23 will synchronously drive the toothed plate 26 to move along the guide trajectory of the loop groove 25. As the toothed plate 26 is displaced, it gradually meshes with the arc-shaped half gear 110. Under the action of gear transmission, the mounting base 11 and the radar detector 12 rotate at the corresponding angle around the rotating shaft 10, thereby realizing the precise deflection of the detection angle of the radar detector 12 and adjusting the detection position. After the angle adjustment is completed, the large friction between the mounting base 11 and the rotating shaft 10 plays a key role. This friction is due to the special surface treatment and structural design of both. When there is no external force driving it continuously, the mounting base 11 can be stably kept in the current position and cannot rotate around the rotating shaft 10 on its own. This effectively ensures the stability of the radar detector 12 after adjustment and avoids affecting the detection accuracy due to shaking or displacement. This angle adjustment process works closely with the rotational motion in Example 1 to achieve comprehensive detection. After the radar detector 12 completes its angle deflection, the dual-axis motor 71 continuously drives the rotating column 7 to rotate the turntable 8, thereby enabling the radar detector 12 to perform circular motion at a new detection angle. During the rotation, the radar detector 12 can detect areas at different orientations and heights. At the same time, the movement of the mounting bracket 4 under the action of the transmission gear 73 and the toothed plate 1 allows the radar detector 12 to cover different horizontal positions. The two work together to enable the radar detector 12 to not only achieve 360-degree rotational detection in the horizontal direction, but also to expand the detection range in the vertical direction through angle adjustment. This allows for the detection of concentrations at multiple locations, avoiding blind spots and enabling comprehensive, all-round detection of the entire detection area. This ensures the accuracy and comprehensiveness of the detection data and provides reliable data support for dust concentration monitoring and distribution analysis.
