Description

Technical Field

[0001] This utility model relates to the field of container damage image acquisition, specifically to an image acquisition module for container damage identification. Background Technology

[0002] Container damage identification is a crucial step in ensuring the safety and quality of cargo transportation. When a container enters the inspection area, an image acquisition module takes pictures of the container's exterior. Based on visual identification, the damage to the container's surface is determined, and data on the damaged parts of the container is recorded from the captured images. The image acquisition module mainly relies on multiple cameras to capture information about the container's outer surface.

[0003] Chinese patent CN213541996U discloses an image acquisition device, including a mounting bracket having an upper side and a lower side arranged opposite to each other; a lighting device fixedly mounted on the mounting bracket; and a camera device including a mounting ring sleeved on the mounting bracket, a camera mounted on the mounting ring and located on the upper side of the mounting bracket, and a locking device located on the mounting ring and located on the lower side of the mounting bracket. The locking device has a loose state to allow the mounting ring to move on the mounting bracket, and a locked state to mount the mounting ring on the mounting bracket. The locking device applies force from below to tightly fit the camera against the upper side of the mounting bracket, thereby ensuring that the camera is at a stable and high height on the mounting bracket.

[0004] According to the aforementioned patent, the patent uses a locking device to limit the camera's movement and shooting position, ensuring the stability of the camera on the mounting bracket. However, the image acquisition camera for capturing and identifying damaged containers is usually installed on a gantry crane. Due to the influence of the high-altitude outdoor environment, the threaded connection structure that fixes the camera installation will loosen over time, leading to shaking of the captured images and the risk of falling from a height. Utility Model Content

[0005] To address the aforementioned issues, an image acquisition module for container damage identification is provided. By reinforcing the installation of the positioning component, the limiting bracket, and the insert, the camera can be stably installed at high altitudes, thus solving the problems of image shakiness and potential falls from heights caused by loose camera installation structures.

[0006] To address the problems of existing technologies, this utility model provides an image acquisition module for container damage identification, including a mounting base. The image acquisition module further includes a limiting bracket mounted on the mounting base, a support frame engaged with the limiting bracket, a protective cover fixedly mounted on the support frame, and a camera rotatably mounted in the protective cover. The limiting bracket has a slot that defines the installation position of the support frame, and the support frame has a strip that engages with the slot. The strip has a positioning component for locking and limiting the installation position of the support frame.

[0007] Preferably, the positioning component includes a strip groove formed on the limiting bracket, and two disc seats that are slidably connected to the insert and engaged with the two ends of the strip groove.

[0008] Preferably, the disc base has a through hole along its own axis, and the limiting bracket has a threaded hole corresponding to the position of the through hole. The diameter of the through hole is larger than the diameter of the threaded hole, and a threaded pin is threaded into the threaded hole.

[0009] Preferably, the insert has an inner groove, a cylindrical rod is fixedly connected in the inner groove, a sliding plate is slidably sleeved on the cylindrical rod, the sliding plate is fixedly connected to the disc seat, and a positioning spring is connected between the sliding plate and the insert.

[0010] Preferably, the protective cover is equipped with an antenna for transmitting camera capture data.

[0011] Preferably, the protective cover is equipped with a steering component for controlling the camera to capture images of the container's exterior.

[0012] Preferably, the steering assembly includes a motor installed in a protective cover, a drive gear connected to the output end of the motor, a gear ring meshing with the drive gear, and the gear ring being coaxially mounted on the camera.

[0013] The advantages of this utility model compared to the prior art are:

[0014] 1. This utility model uses a positioning component to position the installation structure of the reinforcing insert and the limiting bracket. The insert is inserted into the limiting bracket through a slot, and the disc seat in the insert engages with both ends of the strip groove on the limiting bracket. The position of the disc seat after engagement corresponds to the position of the threaded hole on the limiting bracket. When making the threaded connection, the threaded pin passes through the disc seat and then connects with the threaded hole on the limiting bracket, making the threaded connection structure more stable, reducing the impact of the high-altitude installation environment on the threaded connection structure, and ensuring that the camera can be stably installed and used outdoors at high altitudes.

[0015] 2. This utility model can remotely adjust the shooting angle of the camera through the steering component, and remotely control the motor to drive the drive gear to rotate. Through the meshing structure between the drive gear and the gear ring, the camera can be controlled to rotate up and down, so as to expand the shooting angle range of the camera and improve the clarity of the captured images of container damage.

[0024] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0025] See Figures 1-4As shown, the image acquisition module for container damage identification includes a mounting base 1. The image acquisition module also includes a limiting bracket 2 mounted on the mounting base 1, a support frame 31 engaged with the limiting bracket 2, a protective cover 32 fixedly mounted on the support frame 31, and a camera 33 rotatably mounted in the protective cover 32. The limiting bracket 2 has a slot 41 that limits the installation position of the support frame 31. The support frame 31 has a strip 42 that can engage with the slot 41. The strip 42 has a positioning component 43 for clamping and limiting the installation position of the support frame 31.

[0026] The mounting base 1 is fixedly installed on the crossbeam of the gantry crane. The insert 42 on the support frame 31 is inserted into the slot 41 in the limiting bracket 2. The positioning component 43 on the insert 42 can reinforce the position of the insert 42 on the limiting bracket 2, thus initially fixing the installation position of the camera 33.

[0027] See Figures 2-5 As shown, the positioning component 43 includes a strip groove 431 formed on the limiting bracket 2, and two disc seats 432 that are slidably connected to the insert 42 and engaged with the two ends of the strip groove 431.

[0028] The disc base 432 has an inclined structure on the side facing the strip groove 431. Under normal conditions, the disc base 432 protrudes from the surface of the insert 42. When the insert 42 is inserted into the slot 41, the inclined surface of the disc base 432 on the insert 42 is subjected to pressure, causing the disc base 432 to move into the insert 42. When the insert 42 is fully inserted into the slot 41, the disc base 432 and the strip groove 431 on the limiting bracket 2 are aligned front to back. At this time, the disc base 432 is no longer subjected to pressure and moves outward from the inside of the insert 42. The disc base 432 engages with the strip groove 431. The two ends of the strip groove 431 are semi-circular structures. The two disc bases 432 are respectively engaged in the upper and lower semi-circular structures of the strip groove 431. Through the engaging structure, the insert 42 can be initially stably installed on the limiting bracket 2, improving the installation stability of the camera 33.

[0029] See Figures 3-5 As shown, a through hole 44 is provided on the disc base 432 along its own axis, and a threaded hole 45 corresponding to the position of the through hole 44 is provided on the limiting bracket 2. The diameter of the through hole 44 is larger than the diameter of the threaded hole 45, and a threaded pin 46 is threadedly connected in the threaded hole 45.

[0030] When the insert 42 is fully inserted into the slot 41, the position of the through hole 44 in the disc seat 432 corresponds to the position of the threaded hole 45 on the limit bracket 2. The threaded nail 46 is passed through the through hole 44 and contacts the threaded hole 45. The threaded nail 46 is rotated so that it is threadedly connected to the limit bracket 2 through the threaded hole 45. After the thread is tightened, the threaded nail 46 is pressed on the surface of the disc seat 432. The disc seat 432 can further strengthen the threaded assembly structure of the threaded nail 46.

[0031] See Figures 3-5 As shown, the insert 42 has an inner groove 421, and a cylindrical rod 422 is fixedly connected in the inner groove 421. A sliding piece 423 is slidably sleeved on the cylindrical rod 422. The sliding piece 423 is fixedly connected to the disc seat 432. A positioning spring 424 is connected between the sliding piece 423 and the insert 42.

[0032] When the surface of the disc seat 432 is subjected to pressure, the disc seat 432 drives the slider 423 to slide on the cylindrical rod 422. The slider 423 compresses the positioning spring 424 connected to the side. When the surface of the disc seat 432 is not subjected to pressure, the positioning spring 424 is released elastically, pushing the slider 423 and the disc seat 432 to move in opposite directions, so that the disc seat 432 moves and protrudes on the surface of the insert 42, which helps to reinforce the installation of the insert 42.

[0033] See Figure 6 As shown, the protective cover 32 is equipped with an antenna 5 for transmitting data captured by the camera 33.

[0034] Antenna 5 transmits signals that can transmit images captured by camera 33, supporting wireless connection of camera 33. Camera 33 can achieve wireless connection through WiFi hotspot, eliminating the need for network cables and making it more suitable for high-altitude installation environments.

[0035] See Figure 5 and Figure 6 As shown, the protective cover 32 is equipped with a steering component that controls the camera 33 to capture images of the exterior of the container.

[0036] The camera 33 can be adjusted up and down by using the steering component. When the captured image of the container surface is difficult to judge, the camera 33 can be adjusted to capture the image of the container surface again, and a clearer picture can be provided to the back-end management personnel for analysis.

[0037] See Figure 5 and Figure 6 As shown, the steering assembly includes a motor 61 installed in the protective cover 32, a drive gear 62 connected to the output end of the motor 61, a gear ring 63 meshing with the drive gear 62, and the gear ring 63 coaxially mounted on the camera 33.

[0038] The motor 61 can be remotely started. The motor 61 controls the drive gear 62 to rotate. The drive gear 62 controls the gear ring 63 to rotate through meshing transmission. The camera 33, which is fixed to the gear ring 63, is connected to the protective cover 32 and rotates, thereby achieving the purpose of adjusting the shooting angle of the camera 33. The transmission ratio between the drive gear 62 and the gear ring 63 causes the gear ring 63 to rotate at a reduced speed. Through the speed reduction transmission structure, the shooting angle of the camera 33 can be controlled relatively accurately and stably.

[0039] Working principle: When installing the camera 33, first, align the positions of the insert 42 and the slot 41, insert the insert 42 into the slot 41. After insertion, the disc seat 432 on the insert 42 engages in the strip groove 431 on the limiting bracket 2. At this time, the position of the through hole 44 on the disc seat 432 corresponds to the position of the threaded hole 45 on the limiting bracket 2. Install the threaded nail 46 into the threaded hole 45. The threaded nail 46 first passes through the through hole 44 on the disc seat 432. After the threaded nail 46 and the threaded hole 45 are threadedly connected, they are pressed onto the surface of the disc seat 432. The disc seat 432 is positioned between the threaded nail 46 and the threaded hole 45. Due to the constraint of the engagement structure between the disc seat 432 and the strip groove 431, the threaded connection structure of the threaded nail 46 can be strengthened, ensuring that the camera 33 is stably installed and used at high altitudes.

[0040] When capturing images of the container surface, the shooting angle of the camera 33 can be adjusted to improve the clarity of the image capture. The motor 61 controls the drive gear 62 to rotate, which drives the gear ring 63 and the camera 33 to rotate through meshing transmission, thereby driving the camera 33 to rotate up and down, making the shooting angle of the camera 33 clearer so that the back-end management personnel can clearly judge the damage to the container surface.

[0041] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
