Description

Technical Field

[0001] This utility model belongs to the field of grain depot lighting technology, specifically relating to a remote lighting linkage device for grain depots. Background Technology

[0002] In daily grain depot operations, workers need to frequently enter and exit the warehouse to perform tasks such as grain inspection, temperature control monitoring, and ventilation management. As a result, the relevant areas are usually in a closed or semi-closed state, which leads to limited lighting conditions. Under traditional management methods, warehouse lighting mostly relies on independent manual switches for control. If the grain inspection door is not closed in time or personnel forget to turn off the power, the lighting fixtures are likely to be powered on for a long time, which not only increases energy consumption but also hinders warehouse safety management. Especially in some older grain depots, the lighting circuits are scattered, and some switches are inconspicuous or far from the grain inspection door, resulting in low lighting control efficiency during operations.

[0003] Some existing grain depots use simple door control linkage structures for lighting, such as placing contact switches directly on the side of the door frame, triggering the lighting circuit by opening and closing the door. However, such solutions generally suffer from simple structure, exposed location, and insufficient reliability. The switch body is easily affected by dust, moisture, and impact, causing it to fail. At the same time, most of the related electrical components are directly exposed inside the warehouse, lacking the necessary sealing structure and protective housing. After long-term operation, potential hazards such as poor contact may occur. On the other hand, existing door control switches are generally directly connected in series with the lighting circuit, lacking remote control capabilities and unable to be matched with the audible and visual alarm devices, leakage current protectors, or remote linkage units commonly used in modern grain depots, making it difficult to meet the actual needs of multi-scenario operations in grain depots.

[0004] Therefore, there is an urgent need for a remote lighting linkage device for grain depots to solve the problems of existing simple gate control structures, susceptibility to environmental influences, inconvenient maintenance of lighting circuits, lack of sealing protection, and insufficient long-term operational stability. Utility Model Content

[0005] In view of this, this utility model proposes a remote lighting linkage device for grain depots, which addresses the technical problems of simple gate control structure, susceptibility to environmental influences, inconvenient maintenance of lighting circuits, lack of sealing protection, and insufficient long-term operational stability.

[0006] To achieve the above-mentioned technical objectives, the specific technical solution adopted by this utility model is as follows: A remote lighting linkage device for grain depots includes a grain inspection door, a remote lighting control box, an audible and visual alarm, a door position detection component, a positioning mechanism, a leakage current protector, an AC contactor, and a remote control module. The grain inspection door includes a door frame and a door leaf. The door frame includes a horizontal beam arranged along its transverse direction. The door position detection component is fixedly installed on the horizontal beam. A positioning mechanism corresponding to the door position detection component is provided on the upper side of the door leaf, such that the door position detection component and the positioning mechanism are closely aligned when the grain inspection door is closed and separate when the grain inspection door is opened. The remote lighting control box adopts a sealed metal enclosure and is fixedly installed... The system is mounted on the wall outside the grain inspection door. The leakage current protection device, remote control module, and AC contactor are all located inside the remote lighting control box and fixed through the mounting position inside the box. The side of the remote lighting control box has a mains power input interface, and the bottom has a lighting load output port. The audible and visual alarm is fixed on the external side wall of the remote lighting control box and located at the top of the box. The door position detection device is electrically connected to the remote control module through a connecting line set along the side of the grain inspection door. The connecting line uses a flexible cable.

[0007] Furthermore, a mounting base is provided below the crossbeam, and the mounting base is fixed on the mounting surface of the crossbeam. The door position detection component is fixedly connected to the mounting base, and the door position detection component is fixed by the mounting base. The positioning mechanism is installed at the upper edge of the door leaf and is set in a vertically aligned structure relative to the door position detection component.

[0008] Furthermore, the door position detection component includes a detection body, a trigger end connected to the detection body, and a mounting interface for connecting to the mounting base, with the trigger end facing the positioning mechanism.

[0009] Furthermore, the positioning mechanism includes a main body set on the door leaf, a trigger surface set opposite to the trigger end, and a positioning surface for ensuring the consistency of the trigger surface position. The trigger surface is close to the trigger end when the grain inspection door is closed.

[0010] Furthermore, the front of the remote lighting control box is equipped with an openable door that is dustproof, moisture-proof, and waterproof, and is used for the inspection and maintenance of the leakage current protector, remote control module, and AC contactor.

[0011] Furthermore, the remote control module is installed on the side of the residual current device and connected to the AC contactor via conductive lines located inside the remote lighting control box.

[0012] Furthermore, the lighting load output port is electrically connected to the output terminal of the AC contactor to provide power output from the remote lighting control box to the external lighting load.

[0013] By adopting the above technical solution, this utility model can also bring the following beneficial effects: 1. This utility model discloses a remote lighting linkage device for grain depots. By fixing the door position detection component to the crossbeam and achieving a stable connection with the crossbeam through the mounting base, the positioning mechanism set on the side of the door forms a stable alignment relationship with the door position detection component during the opening and closing of the grain inspection door. This avoids the unreliable triggering problem caused by dust, moisture and door body misalignment in traditional side-mounted door control structures. Since the trigger end of the door position detection component and the trigger surface of the positioning mechanism are vertically aligned, the trigger stroke consistency during the opening and closing of the grain inspection door is higher, making the linkage control more stable. This effectively improves the reliability and anti-interference ability of the door control trigger in long-term use, thereby keeping the lighting linkage action of grain inspection operations stable and reliable. It realizes stable detection of the opening and closing status of the grain inspection door and has the advantages of high trigger consistency, strong anti-environmental interference ability and good long-term operational reliability.

[0014] 2. This utility model discloses a remote lighting linkage device for grain depots. By adopting a metal sealed box structure for the remote lighting control box, the leakage current protector, remote control module, and AC contactor are all centrally installed in the mounting position inside the box. An orderly electrical connection is formed through internal conductive lines, so that each electrical component is in a sealed, dustproof, and moisture-proof controlled environment. This avoids the maintenance difficulties, loose wiring, and environmental corrosion problems caused by the scattered installation of electrical components in existing grain depots. By arranging the mains power input interface and lighting load output port of the remote lighting control box in upper and lower sections, the power input and lighting output lines are clearly routed, reducing internal cross wiring and improving the stability and maintenance convenience of the overall electrical structure. It achieves sealed protection of electrical components and reasonable zoning of lines, and has the advantages of stable structure, convenient maintenance, and high electrical connection reliability.

[0015] 3. This utility model discloses a remote lighting linkage device for grain depots. By integrating the door position detection component, positioning mechanism, remote control module, AC contactor, and lighting load output port into an integrated linkage control structure, the mechanical opening and closing action of the grain inspection door can be stably transmitted to the lighting circuit through the electrical components inside the remote lighting control box, thereby realizing automatic lighting control during grain inspection operations. By arranging the door control trigger, control execution, and load output under the protection of an independent metal sealed box, the defects of traditional grain depot lighting devices caused by the dispersed installation of door control components and lighting components, such as loose structure, inconsistent triggering, and unstable electrical connection, are avoided. Effective coordination between mechanical and electrical structures is achieved, improving the lighting linkage response efficiency and safety in grain depot inspection scenarios. It has the advantages of strong overall structure, stable linkage response, and strong adaptability to the grain depot environment. Attached Figure Description

[0023] like Figures 1 to 3 As shown, this utility model provides a remote lighting linkage device for grain depots, including a grain inspection door 4, a remote lighting control box 1, an audible and visual alarm 2, a door position detection component 7, a positioning mechanism 8, a leakage current protector 10, an AC contactor 11, and a remote control module 9. The grain inspection door 4 includes a door frame 6 and a door leaf 5. A horizontal beam 12 is arranged along the upper part of the door frame 6, and a mounting base 13 is arranged below the horizontal beam 12. The mounting base 13 is fixed to the mounting surface of the horizontal beam 12 by threaded fasteners and is used to support the door position detection component 7. The door position detection component 7 is fixedly installed on the mounting surface of the mounting base 13. The door position detection component 7 includes a detection body, a trigger end connected to the detection body, and a mounting interface for fixed connection with the mounting base 13. The detection body adopts a contact-type micro-motion structure and is model LXW5. The trigger end is arranged facing the door leaf 5. The upper side of the door leaf 5 is equipped with a positioning mechanism 8. The positioning mechanism 8 includes a main body, a trigger surface, and a positioning surface. The main body adopts a metal block structure and is fixed to the door leaf 5 by screws or rivets. The trigger surface is arranged opposite to the trigger end of the door position detection component 7, so that the trigger surface is close to the trigger end when the grain inspection door 4 is closed, and the positioning surface ensures the alignment consistency of the two, thereby forming a stable and reliable trigger action during the opening and closing of the grain inspection door 4, avoiding trigger failure caused by dust accumulation or moisture at the bottom.

[0024] The remote lighting control box 1 adopts a sealed metal enclosure structure and is fixed to the outer wall of the grain inspection door 4 with expansion bolts. The front of the remote lighting control box 1 has an openable door, which, along with a sealing strip, provides dustproof, moisture-proof, and waterproof protection. Inside the remote lighting control box 1, there are mounting positions where the residual current device (RCD) 10, the remote control module 9, and the AC contactor 11 are all fixed. The RCD 10 is a DZ47LE series, and the AC contactor 11 is a CJX2 series. The series includes a remote control module 9, which is an industrial remote control device with relay output function. The leakage current protector 10, the remote control module 9, and the AC contactor 11 are all interconnected by conductive lines installed inside a metal sealed enclosure. The conductive lines are insulated copper core wires and are fixed inside the metal sealed enclosure by wire troughs and wire clips to ensure the stability and long-term reliability of the electrical connection. The side of the remote lighting control box 1 is provided with a mains power input interface, which is electrically connected to the input terminal of the leakage current protector 10. The bottom is provided with a lighting load output port, which is electrically connected to the output terminal of the AC contactor 11, and is used to provide load power output to the indoor and outdoor lighting lights, thereby realizing centralized control of multiple lighting loads. The audible and visual alarm 2 is installed on the upper part of the external side wall of the remote lighting control box 1. The audible and visual alarm 2 adopts a 220V industrial type audible and visual alarm component and is fixed to the side wall of the remote lighting control box 1 with screws. The output end of the audible and visual alarm 2 is electrically connected to the signal output end of the remote control module 9. It is used to issue an audible and visual prompt when the grain inspection door 4 is in the open state, so that the on-site operators can be informed of the current lighting linkage status in a timely manner, avoiding energy waste and safety hazards caused by forgetting to turn off the lighting or misoperation.

[0025] The door position detection component 7 is electrically connected to the remote control module 9 via a connecting line 3 arranged along the side of the grain inspection door 4. The connecting line 3 is a flexible cable, which is laid along the outside of the grain inspection door 4 through an insulated cable tray and enters the remote lighting control box 1 through a reserved wire hole near the grain inspection door 4. After entering the remote lighting control box 1, the connecting line 3 is fixed to the wiring structure inside the remote lighting control box 1 by a wire clip, so that the trigger signal of the door position detection component 7 can be stably transmitted to the remote control module 9, avoiding signal instability caused by interference from the opening and closing of the door or external pulling force.

[0026] When this utility model is in use, firstly, when the grain inspection door 4 is opened, the trigger surface of the positioning mechanism 8 separates from the trigger end of the door position detection component 7, and the detection state of the door position detection component 7 changes. After receiving this change signal, the remote control module 9 drives the AC contactor 11 to engage, so that the lighting load output port supplies power to the indoor and outdoor lighting in the grain warehouse. After the grain inspection operation is completed, the grain inspection door 4 is closed, the trigger surface of the positioning mechanism 8 re-applies to the trigger end of the door position detection component 7, and the remote control module 9 controls the AC contactor 11 to cut off the power, so that the lighting load output port stops supplying power and the lighting automatically turns off. At the same time, the audible and visual alarm 2 provides a prompt function during the door opening process.

[0027] In summary, this utility model, through the reliable alignment structure of the door position detection component 7 and the positioning mechanism 8, the centralized installation of the leakage current protector 10 inside the metal sealed box, the remote control module 9 and the AC contactor 11, and the upper prompting arrangement of the audible and visual alarm 2, enables the opening and closing action of the grain inspection door 4 to stably trigger the lighting linkage control. It has the advantages of strong overall structure, high trigger reliability, good electrical protection performance, strong resistance to environmental interference, and convenient maintenance.

[0028] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
