Description

Technical Field

[0001] This invention relates to the field of radar technology, specifically a panoramic scanning millimeter-wave 3D radar device. Background Technology

[0002] Currently, in industrial silos, sheds, and clinker storage facilities for coal, cement, sand, gravel, and grain, material volume measurement, contour scanning, and weight assessment mainly rely on traditional laser scanning radar, single-dimensional level radar, ordinary two-dimensional scanning radar, and manual inventory methods. Traditional scanning equipment relies on a single mechanical transmission structure to achieve scanning detection, primarily used for material point height detection or local contour acquisition, and is gradually being applied to the field of intelligent industrial inventory. Millimeter-wave radar, with its all-weather operation, dust resistance, rain resistance, and unaffected by light, is gradually replacing laser radar as the mainstream detection equipment in harsh industrial environments.

[0003] Most existing scanning radars can only achieve horizontal 360° rotation scanning in large silos and irregularly stacked material scenarios. The vertical angle adjustment range is narrow and the adjustment accuracy is low. They cannot achieve complete three-dimensional spatial coverage, are prone to detection blind spots, and cannot fully capture the three-dimensional contour of the material surface, ultimately resulting in large deviations in volume and weight calculation data. At the same time, the huge amount of material piled up in large silos or stockpiles means that material transportation during the material input or output stage will generate a large amount of dust particles. These dust particles will adhere to the radar dome surface, interfering with the normal detection of the radar, resulting in low radar detection effect. Summary of the Invention

[0004] The purpose of this invention is to provide a panoramic scanning millimeter-wave 3D radar device to solve the problem of low radar detection performance in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A panoramic scanning millimeter-wave 3D radar device includes a housing, in which a radar component is disposed. The housing is composed of a radar dome, a connecting shell, and a tail shell. The two ends of the connecting shell are respectively connected to the radar dome and the tail shell. A cleaning and heat dissipation assembly is disposed on the connecting shell, which includes a cleaning group and a heat dissipation group.

[0007] The cleaning assembly includes a rotating ring rotatably connected to the connecting shell. The rotating ring has several rotating grooves, and a rotating plate is provided in each of the rotating grooves. The rotating plate has several cleaning holes, which are connected to an external water source through pipes. The heat dissipation assembly includes several heat dissipation vents, which are arranged around the axis of the connecting shell. The connecting shell is connected to the outside through the heat dissipation vents.

[0008] The rotating ring revolves around the axis of the housing, driving several rotating plates to rotate. These plates, in turn, drive several cleaning holes to rotate, causing the cleaning holes to revolve around the axis of the housing. During this revolve, external water is supplied to the cleaning holes, which are then transported through pipes and discharged through the holes. The water is sprayed onto the surface of the radome, washing away dust particles and preventing them from affecting radar detection. The radar components inside the housing generate heat during operation, which is then dissipated to the outside through the heat dissipation vents.

[0009] Preferably, the radar assembly includes a top control end assembly, a rotating component and a limiting component, a vertical scanning drive and damping positioning mechanism, and a detection component, wherein the top control end assembly, the rotating component and the limiting component, the vertical scanning drive and damping positioning mechanism, and the detection component are arranged sequentially from the tail end shell towards the radome.

[0010] A fixed mounting bracket is provided on the top of the tail end shell for hoisting the entire equipment or fixing the flange to the top of the silo or shed. At the same time, the top control end component and the control power supply connection end are connected to DCV power supply and RS Ethernet signal interface. The shell is horizontally fixed with a support partition. A support frame is installed at the center of the partition. A rotating cylinder is rotatably assembled inside the support frame through a deep groove ball bearing. The lower end of the rotating cylinder passes through the support partition and is rigidly connected to the rotating part and the limit component. The top of the top control end component is fixedly installed with a first servo motor. The power end of the first servo motor is equipped with a transmission gear. A transmission gear ring is provided on the outer side of the upper end of the rotating cylinder. The transmission gear meshes with the transmission gear ring to form a horizontal rotation drive pair. A support shaft is provided at the bottom of the transmission gear. The inner wall of the control end is equipped with a bearing seat to support the support shaft and limit the radial runout during horizontal rotation.

[0011] The rotating component and limiting assembly includes a rotating component and an electric slip ring. The electric slip ring is coaxially fixedly installed on the upper end of the rotating component. The fixed end of the electric slip ring is connected to the fixed circuit inside the top control end assembly. The rotating end of the electric slip ring is connected to the circuit of all moving parts in the vertical scanning drive and damping positioning mechanism to achieve uninterrupted circuit conduction in the rotation state. Limiting ring blocks are symmetrically welded on the left and right sides of the rotating component. The inner wall of the top control end assembly is provided with a ring-shaped limiting ring frame. The limiting ring blocks slide against the inner side of the limiting ring frame to further constrain the radial displacement of the rotating component and ensure the coaxiality of horizontal rotation. Two sets of symmetrically distributed support side plates extend downward from the bottom of the rotating component. The support side plates extend into the interior of the vertical scanning drive and damping positioning mechanism.

[0012] The vertical scanning drive and damping positioning mechanism includes damping bearings, which are embedded in the bottom of two sets of support side plates. A rotating shaft is horizontally mounted between the two damping bearings. The millimeter-wave radar structure is fixed in the middle of the rotating shaft. A second servo motor is fixed at the bottom of the rotating component. A synchronous belt drive structure is mounted between the power end of the second servo motor and one end of the rotating shaft. The driving wheel is mounted on the output shaft of the second servo motor, and the driven wheel is fixed at the end of the rotating shaft. The synchronous belt is tensioned and mounted between the two wheels. The damping bearings have built-in rubber damping structures, which can provide positioning resistance after the vertical angle is adjusted to prevent the radar structure from shifting due to gravity and equipment vibration.

[0013] The detection component is a radar structure equipped with a millimeter-wave antenna module. The antenna beam angle is optimized to 2°, with a horizontal scanning angle of 360° and an elevation scanning angle of 180°. It is available in three hardware specifications: normal temperature, medium temperature, and ultra-high temperature. The normal temperature version has a detection radius of 30m / 50m, while the high-temperature version can withstand ambient temperatures up to 300℃. The radar component integrates a signal acquisition module to collect distance and azimuth data in real time, converting it into point cloud data for external output. The device uses a two-wire interface, with a power branch and a 100Mbps Ethernet RJ45 network branch. The Ethernet branch is used to transmit point cloud data, and the power branch integrates a 220VAC to 24VDC adapter.

[0014] The device achieves dual-dimensional scanning through brushless motors, enabling continuous 360° horizontal rotation and adjustable vertical angles from 0 to 180°. The first brushless motor operates, driving the rotating cylinder, rotating components, and the radar structure below to rotate horizontally via transmission gears and gear rings, thus achieving full-circumferential scanning. The second brushless motor drives the rotating shaft to rotate via synchronous belt transmission, thereby enabling the radar structure to adjust its vertical pitch angle. The combination of these two dimensions achieves three-dimensional scanning without blind spots.

[0015] Preferably, a rotating shaft is provided in the rotating groove, the rotating plate is connected to the rotating shaft, a power component is provided in the rotating ring, the power component drives the rotating shaft to rotate, a corrugated pipe is also provided on the rotating plate, a water supply pipe is provided in the housing, the two ends of the corrugated pipe are respectively connected to a cleaning hole and a water supply pipe, and the water supply pipe is connected to an external water source.

[0016] The power component drives the rotating shaft to rotate, which in turn drives the rotating plate to rotate, causing the rotating plate to rotate from the rotating groove to the side closer to the radar dome. At the same time, the rotating plate drives the bellows to rotate, causing the bellows to be stretched and lengthened during the rotation. External water is supplied to the bellows through a water pipe installed inside the shell, and then transported to the cleaning port through the bellows.

[0017] Preferably, an air pump and a temperature sensor are installed inside the tail end housing. The air pump is connected to the outside through a pipe, and the output end of the air pump is connected to the inside of the housing.

[0018] After the temperature sensor detects a rise in temperature inside the tail end shell, the controller then controls the air pump to start, which draws in outside air and delivers it into the shell through a pipe.

[0019] Preferably, the heat dissipation assembly further includes a conveying groove, which is disposed within the rotating ring. The conveying groove consists of an input groove, a connecting groove, and an output groove. The input groove is disposed on the side of the rotating ring near the heat dissipation port and is connected to the heat dissipation port. The connecting groove is disposed between the input groove and the output groove. The output groove is disposed on the side of the rotating ring near the outside of the housing. A plurality of bias plates are disposed within the output groove, and the plurality of bias plates are arranged around the axis of the output groove.

[0020] After the air pump draws in outside air, it is delivered to the housing through a pipe. Since the housing is connected to the outside only by a delivery channel, the gas input by the air pump can only be output outward through the delivery channel. Then, the gas is delivered to the input channel through the heat dissipation port, and then from the input channel to the connecting channel. After flowing through the connecting channel, it is delivered to the output channel and finally ejected through the output channel. Because there are several bias plates in the output channel, the bias plates change the direction of the airflow ejected from the output channel, so that the airflow is deflected at a certain angle and output outward through the output channel. In addition, the delivery channel rotates around the housing with the rotation of the rotating ring. The ejected gas forms a spiral airflow under the interaction of the bias plates and the rotating ring. The spiral airflow flows around the outer wall of the radome, thereby further achieving the effect of cleaning the surface of the radome.

[0021] Preferably, a power unit is provided inside the connecting shell, the power unit includes a drive motor and a rotating gear, and a plurality of tooth blocks are provided in the input slot, the plurality of tooth blocks are arranged around the axis of the input slot, and the rotating gear and the plurality of tooth blocks mesh and transmit power.

[0022] The drive shaft of the drive motor drives the rotating gear to rotate, which in turn meshes with several tooth blocks during rotation. These tooth blocks rotate under the action of the rotating gear, causing the rotating ring to rotate. During the rotation of the rotating ring, the conveying trough rotates around the axis of the housing. As the conveying trough rotates, it conveys airflow, allowing the airflow to flow from inside the housing through the conveying trough to the outside of the housing. This achieves airflow circulation inside the housing, and the airflow carries away the heat generated by the radar components, thus achieving a heat dissipation effect.

[0023] Preferably, the outer shell of the connecting shell is provided with a plurality of guide grooves, the guide grooves are located on the side of the connecting shell near the output groove, and the guide grooves are wavy.

[0024] Preferably, a ramp is provided between the guide groove and the output groove.

[0025] After the output slot outputs airflow, it is transported to the guide slot. During the airflow transport process, the airflow will first pass through the ramp, which guides the airflow, causing the airflow to be transported from the small-diameter output slot to the large-diameter guide slot.

[0026] Preferably, the diameter of the guide groove is larger than the diameter of the output groove.

[0027] Because the diameter of the guide groove is larger than that of the output groove, the airflow ejected from the output groove diffuses into the guide groove after passing through the ramp, and further diffuses under the influence of the change in the diameter of the guide groove. This causes the diameter of the annular airflow wall formed by the airflow around the shell to further expand, thereby blocking the dust near the radome and causing it to flow with the airflow in the annular airflow wall. This reduces the impact of dust particles adhering to the radome surface and affecting the detection of the radar components.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] 1. By combining 360° horizontal and 180° vertical large-angle adjustment, it can achieve complete three-dimensional detection space coverage, dual-dimensional full-domain scanning, and completely eliminate blind spots. Compared with traditional single-dimensional scanning radar, it can completely collect the surface contour of irregular stacks and large silos, eliminating scanning blind spots from the structure; thus adapting to different size scenarios such as small silos and large material sheds.

[0030] 2. When the temperature rises, the controller activates the air pump to draw in outside air and deliver it into the housing. The gas enters the input slot through the heat dissipation vent, flows through the connecting slot, and is ejected from the output slot. An offset plate inside the output slot guides the airflow direction, causing it to be deflected outwards at a certain angle. Combined with the rotation of the conveying slot and the rotating ring, the ejected gas forms a spiral airflow under the interaction of the offset plate and the rotating ring, flowing around the outer wall of the radome. The airflow is then guided by a ramp into a larger diameter wave-shaped guide slot, where it further diffuses due to the diameter change, ultimately forming a large-diameter annular airflow wall outside the radome. This annular airflow wall effectively blocks external dust particles from approaching the radome surface and carrying them away with the airflow, further reducing the impact of dust adhesion on radar detection. Furthermore, it achieves forced airflow within the housing, promptly removing the heat generated by the radar components and ensuring reliable operation of the radar components in high-temperature environments.

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] like Figures 1-3 The first embodiment of the present invention shown is a panoramic scanning millimeter-wave 3D radar device, including a housing 1, a radar component 4 disposed inside the housing 1, the housing 1 being composed of a radar cover 11, a connecting shell 12 and a tail end shell 13, the two ends of the connecting shell 12 being connected to the radar cover 11 and the tail end shell 13 respectively, and a cleaning and heat dissipation component 2 being disposed on the connecting shell 12, the cleaning and heat dissipation component 2 including a cleaning group 21 and a heat dissipation group 22;

[0045] The cleaning assembly 21 includes a rotating ring 23, which is rotatably connected to the connecting shell 12. The rotating ring 23 is provided with a plurality of rotating grooves 231, and a rotating plate 232 is provided in the rotating grooves 231. The rotating plate 232 is provided with a plurality of cleaning holes 233, and the cleaning holes 233 are connected to an external water source through pipes. The heat dissipation assembly 22 includes a plurality of heat dissipation ports 24, which are arranged around the axis of the connecting shell 12. The connecting shell 12 is connected to the outside through the heat dissipation ports 24.

[0046] In one specific embodiment of the present invention, the radar assembly 4 includes a top control end assembly, a rotating component and a limiting component, a vertical scanning drive and damping positioning mechanism, and a detection component. The top control end assembly, the rotating component and the limiting component, the vertical scanning drive and damping positioning mechanism, and the detection component are arranged sequentially from the tail end shell 13 to the radar dome 11.

[0047] In one specific embodiment of the present invention, a rotating shaft 234 is provided in the rotating groove 231, the rotating plate 232 is connected to the rotating shaft 234, a power component is provided in the rotating ring 23, the power component drives the rotating shaft 234 to rotate, a corrugated pipe 235 is also provided on the rotating plate 232, a water supply pipe is provided in the housing 1, and the two ends of the corrugated pipe 235 are respectively connected to the cleaning hole 233 and the water supply pipe, and the water supply pipe is connected to an external water source.

[0048] like Figures 4-9 The second embodiment of the present invention shown provides a rotating ring 232 that differs from that in the first embodiment. The difference is that in this embodiment, a conveying groove 3 is provided inside the rotating ring 232, and the rotating ring 232 is driven to rotate by a power unit. This causes the rotating ring 232 to drive the conveying groove 3 to rotate around the axis of the housing 1. When the rotating ring 232 rotates, the heat dissipation gas inside the housing 1 is ejected to the outside through the conveying groove 3. The ejected gas flows along the slope 37 and the guide groove 36, forming an annular airflow wall outside the radome 11, thereby reducing the adhesion of dust particles to the surface of the radome 11 and thus reducing the impact of dust particles on radar detection.

[0049] The specific content is as follows:

[0050] In one specific embodiment of the present invention, the heat dissipation assembly 22 further includes a conveying groove 3, which is disposed within the rotating ring 23. The conveying groove 3 is composed of an input groove 31, a connecting groove 32, and an output groove 33. The input groove 31 is disposed on the side of the rotating ring 23 near the heat dissipation port 24 and is connected to the heat dissipation port 24. The connecting groove 32 is disposed between the input groove 31 and the output groove 33. The output groove 33 is disposed on the side of the rotating ring 23 near the outside of the housing 1. A plurality of bias plates 34 are disposed within the output groove 33, and the plurality of bias plates 34 are arranged around the axis of the output groove 33.

[0051] In one specific embodiment of the present invention, an air pump and a temperature sensor are provided inside the tail end shell 13. The air pump is connected to the outside through a pipe, and the output end of the air pump is connected to the inside of the shell 1.

[0052] In one specific embodiment of the present invention, a power unit 35 is provided inside the connecting shell 12. The power unit 35 includes a drive motor and a rotating gear 351. A plurality of tooth blocks 331 are provided inside the input groove 31. The plurality of tooth blocks 331 are arranged around the axis of the input groove 31. The rotating gear 351 and the plurality of tooth blocks 331 mesh and transmit power.

[0053] In one specific embodiment of the present invention, a plurality of guide grooves 36 are provided on the outer shell of the connecting shell 12. The guide grooves 36 are located on the side of the connecting shell 12 near the output groove 33 and are wavy.

[0054] In one specific embodiment of the present invention, a ramp 37 is provided between the guide groove 36 and the output groove 33.

[0055] In one specific embodiment of the present invention, the diameter of the guide groove 36 is larger than the diameter of the output groove 33.

[0056] Working principle of the invention:

[0057] The rotating ring 23 rotates around the axis of the housing 1. During this rotation, the rotating ring 23 drives several rotating plates 232 to rotate, which in turn drives several cleaning holes 233 to rotate. This causes the cleaning holes 233 to revolve around the axis of the housing 1. During this revolve, a power component drives a rotating shaft 234 to rotate. The rotating shaft 234, in turn, drives the rotating plates 232 to rotate, causing them to move from the rotating groove 231 towards the side closer to the radar dome 11. Simultaneously, the rotating plates 232, in their rotation, drive the bellows 235 to rotate, causing the bellows... During rotation, the pipe 235 is stretched and elongated. External water is supplied to the corrugated pipe 235 through a water supply pipe inside the housing 1, and then to the cleaning hole 233 through the corrugated pipe 235. Water is sprayed from the cleaning hole 233 onto the surface of the radar dome 11, which washes away the dust particles attached to the surface of the radar dome 11, thereby preventing the dust particles from affecting the radar detection. Since the radar component 4 inside the housing 1 generates heat when it is in operation, after the temperature sensor detects the temperature rise inside the tail end housing 13, the controller controls the air pump to start. The air pump draws in outside air and delivers it to the inside of the housing 1 through a pipe.

[0058] After the air pump draws in outside air, it delivers it to the housing 1 through a pipe. Since only the conveying trough 3 is provided in the housing 1 to connect the inside and outside of the housing 1, the gas input by the air pump can only be output to the outside through the conveying trough 3. At the same time, the drive shaft of the drive motor drives the rotating gear 351 to rotate, so that the rotating gear 351 meshes with several tooth blocks 331 during the rotation process. Then, the several tooth blocks 331 rotate under the action of the rotating gear 351, so that the tooth blocks 331 drive the rotating ring 23 to rotate. During the rotation of the rotating ring 23, the conveying trough 3 rotates around the axis of the housing 1. Then, the conveying trough 3 delivers air during the rotation process, so that the airflow flows from the inside of the housing 1 through the conveying trough 3 to the outside of the housing 1, thereby realizing the airflow inside the housing 1. In turn, the heat generated by the operation of the radar component 4 is carried away by the airflow.

[0059] The gas is delivered to the input slot 31 through the heat dissipation port 24, then to the connecting slot 32, and then to the output slot 33 after passing through the connecting slot 32. Finally, it is ejected through the output slot 33. Since there are several bias plates 34 in the output slot 33, the bias plates 34 change the direction of the airflow ejection from the output slot 33, so that the airflow is deflected at a certain angle and output outward through the output slot 33. In addition, the conveying slot 3 rotates around the housing 1 with the rotation of the rotating ring 23, so that the ejected gas forms a spiral airflow under the cooperation of the bias plates 34 and the rotating ring 23, and the spiral airflow flows around the outer wall of the radar dome 11.

[0060] After the output slot 33 outputs airflow, the airflow is transported to the guide slot 36. During the airflow transport process, the airflow will first pass through the ramp 37, which guides the airflow, so that the airflow is transported from the small-diameter output slot 33 to the large-diameter guide slot 36.

[0061] Since the diameter of the guide groove 36 is larger than the diameter of the output groove 33, the airflow ejected from the output groove 33 diffuses into the guide groove 36 after passing through the ramp 37, and further diffuses under the effect of the change in the diameter of the guide groove 36. This causes the diameter of the annular airflow wall formed by the housing 1 to further expand, thereby blocking the dust near the radome 11 and causing it to flow with the airflow in the annular airflow wall. This reduces the impact of dust particles adhering to the surface of the radome 11 on the detection of the radar component 4.

[0062] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
