Description

Technical Field

[0001] This invention relates to the field of classified storage, specifically to a classified device for procurement supply chain. Background Technology

[0002] The ammunition procurement supply chain refers to the procurement and supply chain management system established in the military, law enforcement agencies or other similar organizations to meet the demand for ammunition. This supply chain covers the entire process from ammunition procurement, transportation, storage to distribution. In order to ensure the quality of ammunition and its reliability during deployment, it is necessary to use ammunition storage devices to store the ammunition at storage locations.

[0003] Existing ammunition storage devices simply stack and store ammunition, offering limited functionality and failing to categorize and store different types of ammunition. This makes ammunition retrieval inconvenient and hinders subsequent distribution, inventory, inspection, and maintenance. Furthermore, existing devices lack automatic and uniform ventilation and cooling, as well as the ability to automatically and stably purify volatile chemicals within the ammunition. Consequently, moisture and heat easily accumulate within the ammunition, posing risks of moisture absorption, corrosion, or overheating and explosion, resulting in poor practicality and safety. Moreover, in the event of a fire, existing ammunition storage devices cannot automatically extinguish fires around the storage area, allowing flames to easily contact the ammunition inside and cause an explosion. Therefore, a sorting device for the procurement supply chain is needed to meet users' needs. Summary of the Invention

[0014] The driving circuit board is used to drive the plurality of light-emitting diodes of different wavelengths to emit light of different wavelengths.

[0015] The light-emitting diode is used to illuminate particulate matter in the environment. When the particulate matter is irradiated with light of different wavelengths, optical phenomena occur, resulting in light of different intensities.

[0016] The photosensitive detection unit is used to receive the light transmitted from the light-emitting diode;

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. This invention includes a partition plate and a fixing frame. The combined effect of the desiccant mesh and the partition plate divides the outer casing of the device into four equal storage spaces. The four fixing frames allow for convenient and stable categorized storage of different types of bullets, reducing the risk of accidental explosions and improving storage and management efficiency. This helps reduce retrieval time, improves inventory management and supply distribution efficiency, and facilitates easier monitoring and maintenance of bullet inventory through categorized storage. Clear categorization makes it easier to count, inspect, and maintain the bullets. It also makes it easier to identify expired or low-demand bullets for timely processing and inventory updates. Furthermore, the various storage compartments on the fixing frames allow for layered placement of bullets of the same type, facilitating subsequent retrieval and avoiding the problem of poor ventilation and desiccation caused by large accumulations of bullets.

[0023] 2. This invention includes a moisture-proof and ventilation assembly. A servo motor drives the first air duct to rotate stably. Combined with the meshing of the first and second bevel gears, this drives the exhaust fans on each transmission shaft to rotate simultaneously. In conjunction with the second air duct, the liquid storage tank, and the various through-holes on the first air duct, stable airflow is achieved in each partitioned space. Simultaneously, the desiccant mesh plate enables continuous and stable desiccation. Good ventilation provides airflow, preventing moisture and heat accumulation, thereby reducing the risk of bullets becoming damp, corroded, or overheated. Furthermore, good ventilation prevents the accumulation of harmful gases emitted by the bullets in the storage area, maintaining fresh air for the health and safety of employees. Additionally, the activated carbon mesh plate inside the second air duct purifies volatile chemicals in the bullets, preventing environmental pollution and reducing the risk of fire and explosion.

[0024] 3. This invention incorporates a cooling and fireproofing component. Utilizing the meshing of circular and internal gears, it drives the conveyor cylinder to rotate stably, causing the spiral rod to rotate automatically within the cylinder. This allows for automatic spraying of coolant through nozzles, reducing the temperature of the circulating air and providing energy-efficient and stable cooling to each storage space. This prevents high temperatures from adversely affecting the stored bullets. During the movement of each conveyor cylinder, a mixing plate continuously agitates the coolant, and cooling elements ensure stable cooling. In the event of a fire, a smoke sensor activates a hydraulic rod, which in turn moves the limit frame downwards via a support frame on the connecting plate. The rubber plates on both sides automatically open under the pressure of the nozzles, allowing the coolant to spray automatically around the storage device, thus automatically extinguishing the fire and preventing flames from contacting the bullets inside and causing an explosion. This increases the versatility and safety of the storage device.

[0025] 4. This invention is equipped with casters and rubber suction cups. The mounting bracket can be automatically disassembled and installed using the locking rod and slot. The installed mounting bracket allows for convenient and stable classification and storage of bullets. At the same time, the mounting bracket can push the tray to move automatically upward through the guide plate. With the help of the plug rod, rubber piston and fixing tube, the rubber suction cup can automatically and stably attach the entire storage device to the floor, thus ensuring the stability and safety of the storage device and the stability and safety of subsequent bullet classification and storage. The disassembled mounting bracket can be easily moved using the casters at the bottom, thus ensuring the convenience and efficiency of subsequent bullet transfer and distribution, increasing the versatility and convenience of the storage device.

A rubber suction cup 22 is connected to the bottom end of the fixed tube 16. With the cooperation of the dehumidifying mesh plate 3 and the partition plate 4, the outer shell 1 of the device can be divided into four equal storage spaces.

With the stoppers 20, the rubber pistons 19 and the fixing tubes 16, the rubber suction cup 22 can automatically and stably adsorb and fix the entire storage device to the floor, thereby ensuring the stability and safety of the storage device's placement state. This ensures the stability and safety of the subsequent bullet classification and storage work. The disassembled fixing frame 11 can be easily moved using the universal wheels 14 at the bottom, thereby ensuring the convenience and efficiency of the subsequent bullet transfer and distribution work, and increasing the versatility and convenience of the storage device.

[0056] It should be noted that this invention is a sorting device for a procurement supply chain. First, with the cooperation of the dehumidifying mesh plates 3 on both sides and the corresponding partition plates 4, the outer shell 1 of the device can be divided into four equal storage spaces. Workers can pull the lever 9 on the outer shell 1 outwards until the lever 9 disengages from the slot 10 on the fixing frame 11. At this time, workers can pull the fixing frame 11 outwards, and the fixing frame 11 can move away from the outer shell 1 using the universal wheels 14 at the bottom. Then, workers can place the bullets to be stored in the storage boxes 13 on each fixing mesh plate 12, and place different types of bullets in different fixing frames 11. Using the four fixing frames 11, different types of bullets can be conveniently and stably sorted and stored, reducing the risk of accidental explosions and improving storage and management efficiency. This helps reduce retrieval time, improve inventory management and replenishment efficiency, and further enhances the efficiency of sorted storage. Bullets can be more easily monitored and maintained. With clear classification, it is easier to carry out counting, inspection and maintenance work. At the same time, it is also easier to identify expired or low-demand bullets so that they can be dealt with and updated in a timely manner. Meanwhile, the various storage boxes 13 on the fixed frame 11 can be used to place bullets of the same type in layers, which is convenient for subsequent retrieval and avoids the problem of poor ventilation and dehumidification caused by a large number of bullets piling up. After the bullets are placed stably, the operator can pull the latch 9 on the device housing 1 outward again and push the fixed frame 11 into the device housing 1. Then the operator can release the latch 9. At this time, under the elastic action of the first spring 8, the latch 9 can be driven to automatically engage into the latch slot 10 of the fixed frame 11, so that the fixed frame 11 can be conveniently and stably engaged and fixed. Together with the device housing 1, a stable sealed space can be formed, thereby ensuring the stability of subsequent bullet classification and storage work.

[0057] Furthermore, when the fixing frame 11 moves into the outer casing 1 of the device, the fixing frame 11 can drive the guide plate 15 to insert into the dehumidifying mesh plate 3. At this time, the inclined surface of the side end of the fixing frame 11 can push the tray 21 to move automatically upward. Under the action of the movement of the tray 21, the rubber piston 19 at the bottom can be driven to move automatically upward in the corresponding fixing tube 16 through each stopper rod 20. Under the action of the movement of the rubber piston 19, the internal space of the rubber suction cup 22 can be sucked through the fixing tube 16. At this time, a negative pressure is formed inside each rubber suction cup 22, which can then be used to transfer the moisture through the combination plate 2. The outer casing 1 of the device is automatically and stably attached to the floor, thereby ensuring the stability and safety of the storage device's placement. This ensures the stability and safety of the subsequent bullet sorting and storage. When the device needs to be moved, the individual mounting brackets 11 can be disassembled and transported. At this time, the guide plate 15 can move away from the tray 21. Then, under the elastic action of the second spring 18 at the bottom of the second filter plate 17, the rubber piston 19 can be driven to move downward automatically. At this time, the negative pressure inside the rubber suction cup 22 disappears, thus ensuring that the device can be easily and stably picked up and moved.

[0058] During the operation of the device, the servo motor 501 on the assembly plate 2 drives the first air guide pipe 502 to rotate stably. During this rotation, the first bevel gear 504 drives the meshing second bevel gear 505 to rotate stably, which in turn drives the exhaust fans 507 on each drive shaft 506 to rotate simultaneously. The rotation of each exhaust fan 507 then pushes the air from each storage space to the second air guide pipe 508. Since there is no resistance during airflow, the connection between the second air guide pipe 508 and the liquid storage tank 6, combined with the end of the first air guide pipe 502... The various through holes 503 on the first air duct 502 can form a stable airflow in each storage space. At the same time, in conjunction with the dehumidifying mesh plate 3, it can carry out continuous and stable dehumidification. Good ventilation can provide airflow, prevent moisture and heat accumulation, thereby reducing the risk of bullets getting damp, corroded or overheated. Good ventilation can also prevent harmful gases volatilized from the bullets from accumulating in the storage area, keeping the air fresh to provide health and safety for employees. Furthermore, the activated carbon mesh plate 509 in the second air duct 508 can purify the volatile chemicals in the bullets, avoid environmental pollution, and reduce the risk of fire and explosion.

[0059] During air circulation, the rotation of the first air guide pipe 502 drives the first filter plate 701 and the connecting baffle 710 to rotate simultaneously. The rotation of the first filter plate 701 causes each conveying cylinder 702 to rotate stably. During this rotation, the internal spiral rod 705 rotates stably within the guide groove 708. The spiral rod 705's rotation drives the bottom circular gear 706 to move within the internal gear 707. The meshing of the circular gear 706 and the internal gear 707 drives the spiral rod 705 to rotate automatically within the conveying cylinder 702. At this time, the liquid storage tank... The coolant stored inside the tank 6 has a liquid level lower than the height of the first filter plate 701. It can be automatically and uniformly transported to the nozzle 703 through the conveying cylinder 702. Then, the nozzle 703 can spray the coolant steadily. With the revolution of each nozzle 703, the coolant can be evenly sprayed into the storage tank 6. At this time, the continuously sprayed coolant can reduce the temperature of the circulating air, thereby providing energy-saving and stable cooling treatment for each storage space, avoiding the adverse effects of high temperature on the bullets during storage. In addition, during the movement of each conveying cylinder 702, the mixing plate 704 can continuously stir the coolant, and with the cooling plate 709, the stability of the continuous cooling operation of the coolant can be ensured.

[0060] When the storage device encounters a fire, the smoke sensor 717 drives the hydraulic rods 711 on both sides. The hydraulic rods 711 then drive the connecting plate 712 to move downwards stably. During the movement of the connecting plate 712, the support frame 713 drives the limiting frame 714 to move downwards automatically within the sealing gasket 716. Under the action of the limiting frame 714, the rubber plates 715 on both sides come into contact with and are pressed against the nozzles 703. Under the contact and pressing action of the nozzles 703, the joint of the rubber plates 715 on both sides is pushed up, so the nozzles 703 can pass through the joint of the rubber plates 715 on both sides and be exposed to the outside. Subsequently, under the continuous operation of the nozzles 703, the coolant sprayed by each nozzle 703 can be automatically sprayed around the storage device under the rotation of the nozzles 703, thereby automatically extinguishing the fire around the storage device and preventing the flames from contacting the bullets inside the storage device, which could cause the accumulated bullets to explode.

[0061] In this invention, the smoke sensor 717 is also used to detect the smoke concentration value in the environment to determine whether there is a fire and the smoke situation. Specifically, the smoke sensor 717 includes several light-emitting diodes of different wavelengths, a driving circuit board, a photosensitive detection unit, a gas-sensitive resistor, and a control unit.

[0062] The driving circuit board is used to drive the several light-emitting diodes of different wavelengths to emit light of different wavelengths;

[0063] Light-emitting diodes (LEDs) are used to illuminate particulate matter in the environment. When particulate matter is irradiated with light of different wavelengths, optical phenomena occur, resulting in light of different intensities.

[0064] The photosensitive detection unit is used to receive the light transmitted from the light-emitting diode;

[0065] The control unit is connected to the photosensitive detection unit. The control unit calculates the power value of each wavelength based on different light intensity values, forms a feature matrix based on the power value of each wavelength, compares the feature matrix values ​​with a preset standard matrix, and confirms the type of particulate matter based on the comparison results.

[0066] Gas-sensitive resistors are used to detect the concentration of smoke in the environment and transmit the detected smoke concentration value to the control unit;

[0067] The device housing 1 is equipped with a microcontroller and a buzzer. The microcontroller is connected to the control unit. The microcontroller compares the type of particulate matter with the type of particulate matter in the preset risk particulate matter set. When the particulate matter falls into the risk particulate matter set, it determines that the smoke containing the type of particulate matter in the current environment needs to be warned by the buzzer when the preset concentration is reached.

[0068] The principle and effect of the above technical solution are as follows: For general smoke sensors, they can generally only detect the smoke concentration value in the environment. For example, during a fire, especially in the early stage of a fire, the fire source emits a small amount of smoke particles that are difficult to be observed by the human eye. These particles contain gases such as carbon monoxide, carbon dioxide, methane, water, sulfur dioxide, and nitrogen oxides, as well as larger molecular clusters, unburned material particles, and suspended matter such as combustion ash. However, in real-world applications, even before a fire occurs, dust, moisture, and other particulate matter entering the smoke detector can trigger false alarms. Furthermore, smoke detectors are prone to dust accumulation over long periods, leading to false alarms and affecting their accuracy. Therefore, it is necessary to make a preliminary judgment on the type of particulate matter detected by the smoke sensor. This invention uses a light-emitting diode (LED) within the smoke sensor to illuminate environmental particulate matter. By analyzing the light intensity of different wavelengths under illumination, the power value of each wavelength is calculated. This power value is then compared with a preset standard matrix composed of different types of particulate matter to determine the type of particulate matter. Combined with the smoke concentration, the smoke concentration in the environment and the type of particulate matter causing this concentration can be determined. This dual judgment results in more accurate smoke detection and effectively avoids false detections caused by dust and other factors. This invention also incorporates a microcontroller and a buzzer on the device casing 1, enabling it to issue an early warning when the smoke condition meets the warning criteria, thus improving the overall safety performance of the sorting device used in the supply chain.

In particular, as long as there is no structural conflict, the features in the disclosed embodiments can be combined with each other in any manner.
