Description

Technical Field

[0001] This invention belongs to the field of security inspection equipment technology, specifically an automatic dehumidification device for a security inspection instrument. Background Technology

[0002] Security scanners are electronic devices that use conveyor belts to transport luggage into X-ray inspection channels for examination. They are widely used in security monitoring in large public places such as airports, train stations, and subway stations. With the rapid development of urban rail transit and air transport, the number and frequency of use of security scanners have increased significantly, and their operational stability and cleaning and maintenance issues have received increasing attention.

[0003] In rainy weather, passengers' rain gear often retains a lot of water, which can be carried into the security check area during the process, causing water stains and slippery surfaces on the conveyor belt. This not only affects the normal transport of luggage but also makes the bottoms of subsequent luggage items prone to getting wet. Furthermore, the damp conveyor belt surface easily attracts dust and other contaminants, further exacerbating its dirtiness. During continuous operation, water stains may also seep into the security scanner, corroding delicate electronic components such as X-ray generators, affecting the equipment's lifespan and detection accuracy.

[0004] Previously, this potential hazard was mainly addressed by security personnel repeatedly wiping the conveyor belt manually with cloths. However, this method has the following shortcomings: First, during peak passenger flow periods on rainy days, security personnel are busy, and manual wiping increases their workload, and the frequency of wiping is limited by manpower. Second, manual wiping is delayed, making it impossible to clean water stains on the conveyor belt immediately, and wiping may be delayed. Third, the security scanner contains an X-ray generator, and manual cleaning during equipment operation poses a certain radiation safety hazard; cleaning while the machine is shut down affects security efficiency. Fourth, delayed wiping can cause passengers' bags to get wet from rain, affecting their travel experience. In addition, although some existing technologies have devices for dehumidifying the internal environment of security equipment, such as solutions using semiconductor cooling chips for air dehumidification, these devices mainly control the humidity inside the equipment, rather than automatically cleaning water stains on the conveyor belt surface, and cannot solve the problem of liquid water stains on the conveyor belt surface.

[0005] Therefore, there is an urgent need for a device that can automatically clean water stains on the surface of the conveyor belt without increasing energy consumption or affecting the normal operation of the security inspection equipment.

[0006] The information disclosed above in this background section is only for enhancing the understanding of the background section of this invention, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0007] The purpose of this invention is to provide an automatic dehumidification device for security scanners to solve the problems in the prior art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an automatic dehumidification device for a security scanner, comprising:

[0009] The base has side plates on both sides, and multiple sets of mounting holes are provided on the side plates along the vertical direction.

[0010] The roller has an integrally formed rotating shaft along its central axis, and connecting blocks are rotatably connected to both ends of the rotating shaft. The connecting blocks are installed on the side plate through mounting heads, and a removable absorbent layer is attached to the outer surface of the roller.

[0011] Preferably, the bottom surface of the base is provided with an anti-slip pad. By providing an anti-slip pad, the friction between the device and the ground can be increased, preventing the device from shifting during operation and ensuring the stability of the dehumidification operation.

[0012] Preferably, the mounting head is inserted into the mounting hole and locked in place by a mounting nut. This insertion and locking mechanism with the nut allows for detachable fixing of the connecting block to the side plate, facilitating the installation, disassembly, and height adjustment of the device.

[0013] Preferably, the base is provided with a counterweight. By setting the counterweight, the overall stability of the device can be increased, preventing the device from shaking or shifting due to uneven force during the rotation and wiping process of the roller.

[0014] Preferably, the removable absorbent layer is a sponge absorbent layer or a microfiber absorbent layer. Sponge and microfiber materials have good water absorption properties and flexibility, which can effectively absorb water stains on the surface of the conveyor belt. At the same time, the removable design facilitates the periodic replacement or cleaning of the absorbent layer.

[0015] Preferably, the detachable absorbent layer is detachably connected to the roller via Velcro or snap fasteners. Using Velcro or snap fasteners facilitates quick assembly and disassembly of the absorbent layer, reducing maintenance difficulty and replacement costs.

[0016] Preferably, the multiple sets of mounting holes are arranged at equal intervals along the vertical direction. This equal-interval arrangement of mounting holes allows for flexible selection of different installation positions based on the height of the conveyor belt, enabling adaptation to conveyor belts of different heights for security inspection equipment.

[0017] Preferably, the axial length of the roller is greater than or equal to the width of the security scanner conveyor belt. This ensures that the roller can completely cover the width of the conveyor belt, achieving thorough wiping of water stains on the conveyor belt surface.

[0018] Preferably, a bearing is provided between the connecting block and the rotating shaft. The bearing reduces the frictional resistance when the rotating shaft rotates, allowing the roller to rotate smoothly with the conveyor belt, reducing operating noise and extending the service life of the device.

[0019] Preferably, the side panel and the base are integrally formed or welded together. Integral forming or welding ensures the connection strength between the side panel and the base, improving the overall structural rigidity and stability of the device.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. This invention is highly practical and adaptable, requires no additional energy consumption, and realizes the normalized automatic cleaning of water stains on the conveyor belt, completely replacing the traditional manual wiping operation. It not only effectively reduces the workload of security inspectors and saves labor costs, but also keeps the surface of the conveyor belt dry and clean, eliminates the risk of slippery equipment, and prevents passengers' luggage from getting wet from rain. It effectively optimizes the travel experience of passengers and improves the level of security service guarantee at the station.

[0022] 2. This invention uses multiple sets of mounting holes opened vertically on the side plate to allow the installation height of the roller to be flexibly adjusted according to the height of the conveyor belt of different models of security inspection equipment. It can be adapted to most security inspection equipment on the market, has strong versatility, and a wide range of applications.

[0023] 3. The present invention, through the setting of a detachable water-absorbing layer, allows the water-absorbing layer to be easily removed, replaced or cleaned after long-term use when it becomes saturated with water, without the need for a complete replacement device, which greatly reduces the later maintenance costs. At the same time, the detachable water-absorbing layer fits tightly against the roller surface, ensuring the wiping effect on the conveyor belt surface.

[0024] 4. This invention has a simple structure, low cost, and requires no external power supply or drive mechanism. It is driven entirely by the power of the conveyor belt itself, which is energy-saving and environmentally friendly. It does not change the original structure and operation mode of the security inspection device, is easy to install, and can be quickly retrofitted to existing security inspection devices.

[0031] To enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0032] Example 1:

[0033] An automatic dehumidification device for a security inspection instrument includes a base 1 and a roller 6. Side plates 2 are provided on both sides of the base 1. The side plates 2 are integrally formed with the base 1 or welded together, thereby ensuring the connection strength between the side plates 2 and the base 1 and improving the overall structural rigidity and stability of the device. Multiple sets of mounting holes 201 are formed vertically on the side plates 2. An anti-slip pad 8 is provided on the bottom surface of the base 1 to increase the friction between the device and the ground, preventing displacement during operation and ensuring the stability of the dehumidification operation. A counterweight is also provided on the base 1 to increase the overall stability of the device and prevent the roller 6 from shaking or shifting due to uneven force during rotation and wiping.

[0034] A rotating shaft 5 is integrally mounted on the roller 6 along its central axis. Connecting blocks 3 are rotatably connected to both ends of the rotating shaft 5. Bearings are installed between the connecting blocks 3 and the rotating shaft 5 to reduce frictional resistance during rotation, allowing the roller 6 to rotate smoothly with the conveyor belt, reducing operating noise and extending the device's service life. The connecting blocks 3 are mounted on the side plate 2 via mounting heads 4, which are inserted into mounting holes 201 and locked in place by mounting nuts 9. By selecting mounting holes 201 of different heights, the installation height of the roller 6 can be adjusted to accommodate the height of conveyor belts for different models of security inspection instruments.

[0035] A removable absorbent layer 7 is attached to the outer surface of roller 6. This removable absorbent layer 7 is either a sponge absorbent layer or a microfiber absorbent layer. The removable absorbent layer 7 is detachably connected to roller 6 via Velcro or clips, facilitating quick installation and removal, reducing maintenance difficulty and replacement costs. The axial length of roller 6 is greater than or equal to the width of the security scanner conveyor belt. This ensures that roller 6 can completely cover the width of the conveyor belt, achieving thorough wiping of water stains on the conveyor belt surface.

[0036] Working principle: This device is installed at the front and rear ends of the security inspection conveyor belt. During installation, select the appropriate mounting hole 201 according to the height of the conveyor belt, insert the mounting head 4 into the corresponding mounting hole 201, and then lock it with the mounting nut 9. This ensures that the removable absorbent layer 7 on the outer surface of the roller 6 maintains appropriate contact with the surface of the conveyor belt, i.e., slight squeezing contact, to ensure that the removable absorbent layer 7 can effectively absorb water stains without hindering the normal operation of the conveyor belt.

[0037] After the security scanner is activated, the conveyor belt continues to operate under the drive of its own motor. When the portion of the conveyor belt with water stains moves to the position of roller 6, the friction between the removable absorbent layer 7 and the conveyor belt surface causes roller 6 to rotate around shaft 5. During the rotation of roller 6, the removable absorbent layer 7 continuously moves relative to the conveyor belt surface, absorbing all the water stains on the conveyor belt surface. The absorbed water is temporarily stored inside the removable absorbent layer 7.

[0038] Once the removable absorbent layer 7 is saturated with water, the operator can remove it from the roller 6, wring it out, clean it, or replace it with a new absorbent layer, and then reinstall it for continued use.

[0039] The entire process requires no external power supply or additional drive mechanism, relying entirely on the power of the security inspection machine's conveyor belt itself. This achieves automated and routine cleaning of water stains on the conveyor belt, effectively solving the problems of lag and low efficiency associated with manual wiping.

[0040] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0041] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0042] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
