Technical Field

[0001] This utility model belongs to the technical field of bidirectional opening and closing heat-insulating and safe intelligent grain warehouse inspection doors, specifically relating to bidirectional opening and closing heat-insulating and safe intelligent grain warehouse inspection doors. Background Technology

[0002] The bidirectional, insulated, and intelligent grain silo inspection door is a key piece of equipment for ensuring a safe grain storage environment. It features bidirectional opening, allowing for smooth opening and closing even in the event of internal or external collisions, and a seamless return to its original position. This greatly facilitates staff access to the grain silo in various scenarios, improving work efficiency. In terms of insulation, the door uses high-quality insulation materials, such as polyurethane, with a low thermal conductivity, effectively blocking heat exchange between the inside and outside of the silo and maintaining a stable internal temperature. Whether in hot summers or cold winters, it prevents temperature fluctuations from affecting grain quality and reduces losses due to temperature issues. For safety, its robust structure can withstand certain external impacts. It is also equipped with intelligent locks and multiple sealing designs, preventing the entry of external moisture, dust, and pests, and providing excellent anti-theft functionality to ensure a safe grain storage environment. Furthermore, if a person or object is detected passing through the door while it is closing, it will automatically open to prevent accidents. The door is highly intelligent and can be connected to a grain silo management system for remote monitoring and operation, providing strong support for modern grain storage management.

[0003] Currently, the existing two-way opening and closing insulated and heat-insulating smart grain warehouse inspection doors are usually connected to the door frame by hinges. Therefore, when staff open the insulated door to enter the grain warehouse for inspection, they may forget to close the door. If the insulated door is left open for a long time, external heat will enter the grain warehouse, causing the internal temperature of the grain warehouse to rise and affecting the storage of grain inside the grain warehouse.

[0024] Please see Figures 1-5 The present invention provides the following technical solution: a two-way opening and closing heat-insulating and safe intelligent grain warehouse inspection door, including an outer door frame 1, an insulated door 2 rotatably connected to the inner side of the outer door frame 1, a sealing strip 3 bonded to the outer wall of the insulated door 2, a door lock 4 installed on the surface of the insulated door 2, an outer pull rod 5 connected to one end of the door lock 4, and an inner pull rod 6 connected to the back of the insulated door 2.

[0025] An inner door frame 7 is fixedly connected to the inner wall of the outer door frame 1. An alarm switch 8 is installed on the surface of the inner door frame 7. An alarm 9 is installed on the surface of the outer door frame 1. Two plugs 10 are fixedly connected to the back of the alarm 9. A slot 11 is opened on the outer wall of the plug 10. A mounting base 12 is fixedly connected to the surface of the outer door frame 1. A spring 13 is installed inside the mounting base 12. A movable block 14 is connected to the end of the spring 13. A locking pin 15 is fixedly connected to one end of the movable block 14. A connecting sleeve 16 is connected to the end of the mounting base 12.

[0026] It should be noted that the sealing strip 3 can seal the door gap. By pulling the outer lever 5 and using the key, the door insulation 2 can be opened from the outside, and by pulling the inner lever 6, the door insulation 2 can be opened from the inside, thus realizing the bidirectional opening and closing of the door insulation 2.

[0027] It is also worth noting that the interior of the insulation door 2 is filled with a polyester foam insulation layer, and the outer surface of the insulation door 2 is coated with a nano-reflective coating.

[0028] Preferably, one end of the locking pin 15 is inserted through the interior of the connecting sleeve 16, and the end of the locking pin 15 away from the movable block 14 is adapted to the size of the slot 11. The alarm 9 can form an elastic locking structure with the outer door frame 1 through the insert block 10, the slot 11, the mounting base 12, the spring 13, the movable block 14, the locking pin 15, and the connecting sleeve 16. One end of the insert block 10 can be inserted through the interior of the connecting sleeve 16.

[0029] In practical use, the movable block 14 is moved by the lever to retract the locking pin 15. Then, the insert block 10 on the back of the alarm 9 is inserted into the connecting sleeve 16. At this time, the lever is released and the locking pin 15 will pop out under the action of the spring 13 and insert into the slot 11, thus installing the alarm 9 on the surface of the outer door frame 1. Then, the alarm switch 8 is installed on the surface of the inner door frame 7. When the insulated door 2 is closed, the insulated door 2 will press the alarm switch 8 to turn off the alarm 9. Conversely, when the insulated door 2 is opened, the button on the alarm switch 8 will be released, thus activating the alarm 9 to sound an alarm to remind the staff to close the insulated door 2 and prevent external heat from entering the grain silo.

[0030] It should be noted that by moving the movable block 14 with the lever, the locking pin 15 is retracted, allowing one end of the locking pin 15 to disengage from the slot 11. Then, the alarm 9 is pulled outward to disengage the insert 10 on its back from the connecting sleeve 16, thus completing the disassembly of the alarm 9 and facilitating subsequent maintenance.

[0031] It is also important to note that the alarm 9 is electrically connected to the alarm switch 8, and the alarm 9 is powered by an external power source.

The two ends of the cotton cloth sleeve 17 can be connected by the Velcro velvet surface 18 and the Velcro hook surface 19.

[0033] In practical use, the cotton cloth cover 17 is wrapped around the outer wall of the outer pull rod 5, and then the Velcro hook side 19 sewn at one end of the cotton cloth cover 17 is glued to the Velcro fleece side 18 at the other end, so that the cotton cloth cover 17 is attached to the outer wall of the outer pull rod 5, thereby preventing the staff from directly contacting the outer pull rod 5 which has been exposed to the sun for a long time when opening the door.

[0034] Working principle: First, by moving the movable block 14 with the lever, the locking pin 15 is retracted. Then, the insert 10 on the back of the alarm 9 is inserted into the connecting sleeve 16. At this time, releasing the lever and locking pin 15 will cause it to pop out under the action of the spring 13 and insert into the slot 11, thus installing the alarm 9 on the surface of the outer door frame 1. Then, the alarm switch 8 is installed on the surface of the inner door frame 7. When the insulated door 2 is closed, the insulated door 2 will press the alarm switch 8 to turn off the alarm 9. Conversely, when the insulated door 2 is opened, the button on the alarm switch 8 will be released, thus activating the alarm 9 to sound an alarm to remind the staff to close the insulated door 2 and prevent external heat from entering the grain silo. Furthermore, by wrapping the outer wall of the outer pull rod 5 with the cotton cloth cover 17, and then attaching the Velcro hook side 19 sewn at one end of the cotton cloth cover 17 to the Velcro fleece side 18 at the other end, the cotton cloth cover 17 is attached to the outer wall of the outer pull rod 5, thus preventing the staff from directly contacting the outer pull rod 5 which has been exposed to the sun for a long time when opening the door.
