Description

Technical Field

[0001] This invention provides a three-dimensional scanning system for material management in silos, belonging to the field of level measurement technology. Background Technology

[0002] Currently, material management within silos is generally achieved using 3D scanning radar for safe material handling during loading and unloading. However, in practice, to ensure the silo's structural stability and robustness, additional supporting structures are often added to its top and interior. The number and type of these supporting structures vary depending on the container, including I-beam structures and complex, interwoven steel structures. The materials stored inside the silo require 3D scanning radar to measure and acquire their characteristic information based on ranging principles. However, these interfering structures can obstruct the radar's ranging signal, generating interference and significantly impacting the measurement results.

[0003] In addition, a large amount of dust will be present in the air during the material feeding or discharging process. This dust will greatly affect the measurement of laser signals. If microwave signals are used for measurement, there is a problem of low measurement accuracy.

[0004] Therefore, there is an urgent need in this field for a 3D scanning system for material management in silos that can avoid interference and improve measurement accuracy. Utility Model Content

[0005] To address the problems of low measurement accuracy and inability to avoid interference in existing 3D scanning radar systems for silos, this invention proposes a 3D scanning system for material management in silos. The aim is to improve the installation structure of the 3D scanning radar to enable it to adapt to material measurement in different scenarios.

[0006] The technical solution adopted by this utility model is: a three-dimensional scanning system for material management in silos, including a protective shell, a sliding rail, a fixed plate, a driving device and a scanning device;

[0007] The protective shell is fixed to the top of the silo. A movable slide rail is installed on the inner wall of the protective shell. The movable slide rail is slidably connected to the fixed plate. A push rod is installed at the top of the fixed plate, and a scanning device is installed at the bottom of the fixed plate.

[0008] The top of the push rod is connected to the drive device, which drives the push rod to move, thereby causing the scanning device to move up and down.

[0009] Furthermore, through holes are provided at the top of the silo and the bottom of the protective shell corresponding to the position of the scanning device, so that the scanning device can enter and exit the interior of the silo.

[0010] Furthermore, two longitudinal sliding rails are symmetrically arranged on the inner wall of the protective shell, the fixed plate and the two sliding rails form an H-shaped structure, and the scanning device and the fixed plate form a T-shaped structure.

[0011] Furthermore, an openable baffle is provided on the protective shell at the position corresponding to the through hole.

[0012] Furthermore, a recessed bracket is installed at the bottom of the fixed plate, and a scanning device is installed at the end of the recessed bracket.

[0013] Furthermore, the sunken support is a detachable multi-segment support.

[0014] Furthermore, the recessed support has a hollow interior structure to accommodate the cables of the scanning device.

[0015] Furthermore, the two ends of the fixed plate are sliding parts, and the two sliding parts are slidably connected to two moving slide rails respectively.

[0016] Furthermore, the scanning device employs a D-type laser scanning radar.

[0017] Furthermore, an extension is provided at the end of the baffle, and the extension forms an L-shaped structure with the baffle. The extension is located outside the protective shell when the baffle is closed.

[0018] The advantages of this utility model over the prior art are as follows:

[0019] 1. This utility model can control the scanning device to enter and exit the silo through a drive device. Specifically, the moving slide rail matches the sliding part and the motor drives the fixed plate to move, thereby driving the scanning device to move up and down inside the silo, thus avoiding interference at the silo opening.

[0020] 2. This utility model uses a sinking support to meet the needs of scanning materials inside silos of different sizes.

[0021] 3. This utility model sets the sinking support as a multi-section detachable structure, so that the length of the sinking support can be adjusted according to the needs to meet the scanning of materials in silos of different sizes.

[0022] 4. By setting a baffle, material information can be measured by laser signal when the silo is in a static state, i.e., not in a dynamic state of feeding or discharging. This avoids the influence of dust on the laser signal and improves the measurement accuracy. Thus, the characteristic data of the material in the silo can be intelligently acquired by scanning radar, and the data can be processed, managed and displayed in three dimensions by the central control equipment that communicates with the scanning device, so as to realize intelligent data management.

[0031] like Figures 1 to 6 As shown, this utility model provides a three-dimensional scanning system for material management in silos, including a scanning device 8 and a protective shell 2. The protective shell 2 is fixed to the top of the silo 1 containing the material. A movable slide rail 4 is installed on the inner side wall of the protective shell 2. A fixed plate 5 is slidably connected to the movable slide rail 4. The end of the fixed plate 5 is a sliding part that can slide within the movable slide rail 4. A push rod 3 is installed at the top of the fixed plate 5. The top of the push rod 3 is connected to a driving device 7. The scanning device 8 is installed at the bottom of the fixed plate 5.

[0032] The drive device 7 can push the fixed plate 5 to move on the sliding rail 4 through the push rod 3, thereby driving the scanning device 8 to rise and fall, realizing the free adjustment of the detection depth of the scanning device 8.

[0033] The top of the silo 1 has a through hole for the scanning device 8 to enter and exit the silo 1 during lifting and lowering. The protective shell 2 has an opening matching the entry and exit of the scanning device 8, and a baffle is provided at the corresponding position of the through hole of the protective shell 2 to isolate the scanning device 8 from the silo 1. When the silo 1 is not in the feeding or discharging state, the baffle is opened to allow the scanning device 8 to enter the silo 1; when the silo 1 is in the feeding or discharging state, the baffle is closed to restrict the scanning device 8 from entering the silo 1, and at this time the baffle blocks the through hole on the protective shell 2.

[0034] Furthermore, an extension is provided at the end of the baffle, forming an L-shaped structure with the baffle. The extension is located outside the protective shell 2 when the baffle is closed. The baffle is configured as a light-transmitting plate, and the scanning device 8 can transmit and receive detection signals, such as microwave signals, through the light-transmitting plate to scan the surface of the material inside the silo 1 to obtain material characteristic information.

[0035] The through-hole design allows the scanning device 8 to move up and down within the silo 1 or the protective shell 2. This helps to prevent interference from objects within the silo 1, ensuring measurement accuracy and effectiveness.

[0036] In this embodiment, the protective shell 2 can be set as a rectangular shell, a cylindrical shell, or a simple fixed side plate, as long as it can achieve the fixed installation of the movable slide rail 4 and the push rod 3.

[0037] In this embodiment, at least one movable slide rail 4 is provided, which is sufficient to ensure that the sliding part of the fixed plate 5 can slide within the movable slide rail 4.

[0038] In a preferred embodiment, the movable slide rail 4 can be symmetrically installed on the inner wall of the protective shell 2 along the longitudinal direction. In this case, both ends of the fixed plate 5 are provided with sliding parts that slide on the corresponding movable slide rail 4, and the push rod 3 is fixed at the center position of the fixed plate 5 to ensure the balance of the equipment. The sliding part can be a slide table or a roller, as long as it can slide on the movable slide rail 4.

[0039] In this embodiment, the installation position of the movable slide rail 4 is not specifically limited. When two movable slide rails 4 are installed, they can be installed symmetrically front and back or symmetrically left and right, as long as the system can operate stably.

[0040] In this embodiment, the control terminal of the drive device 7 and the control terminal of the scanning device 8 are respectively connected to the central control equipment through wires to realize the electrical control, data acquisition and communication of the drive device 7 and the scanning device 8.

[0041] In this embodiment, a sinking bracket 6 can also be installed between the fixed plate 5 and the scanning device 8. The sinking bracket 6 can further increase the lifting range of the scanning device 8, making it suitable for silos with a relatively deep cylinder depth.

[0042] The scanning device 8 can be directly fixedly connected to the fixing plate 5 (e.g., Figure 3 (As shown), it can also be indirectly fixed to the fixing plate 5 through the sunken bracket 6 (as shown). Figure 4-6 (As shown). If the scanning device 8 is fixedly connected to the fixing plate 5 via the recessed bracket 6, the recessed bracket 6 is preferably configured as a detachable multi-segment bracket (e.g., Figure 6 As shown in the figure, this allows you to select the matching length based on the size of silo 1.

[0043] Specifically, the sinking support 6 may include at least one first support or one or more second supports, with the first support and at least one second support connected by a flange. If both a first and a second support are provided, a flange is provided at the connection point of the two supports, and then the connection is secured with nuts. Of course, the sinking support 6 can also be a single, independent support; however, to facilitate production and adapt to the needs of silos 1 of different sizes, it is preferable to configure the sinking support 6 as a detachable, multi-segment support, i.e., it can be configured as multiple small-sized supports. If the silo 1 is large, connecting multiple first and second support segments allows the scanning device 8 to scan the entire area of ​​the material inside the silo 1. Figure 5 and 6 As shown, Figure 5 The sunken support 6 in the middle is a structure with multiple supports connected together. Figure 6 The sunken support 6 in the middle is a single independent support structure.

[0044] Because lidar has high measurement accuracy, and in order to obtain high-precision measurement information while reducing interference or attenuation of the laser signal by dust and other impurities, the scanning device 8 in this invention is preferably a 3D laser scanning radar. During the feeding process, a large amount of dust is generated. At this time, a baffle can be used to block the through-hole on the protective shell, i.e., close the baffle, thus confining the 3D laser scanning radar within the protective shell 2. Once feeding is complete and the dust is minimal or nonexistent, the baffle is opened, and the drive device 7 drives the push rod 3 to move. The push rod 3 pushes the 3D laser scanning radar below the fixed plate 5 into the silo 1, thereby achieving a three-dimensional scan of the material surface using laser signals to obtain the material's three-dimensional feature information.

[0045] In this embodiment, the sinking bracket 6 can be configured as a hollow structure, which is used to accommodate the cables of the scanning device 8.
