[0019] Example:

[0020] Please refer to Figure 1 According to one aspect of this application, one embodiment provides a multi-passage warehouse safety linkage delayed unlocking protection device, which is installed on a single door 1 of the multi-passage warehouse, which is made of welded steel for maintenance personnel to enter and exit, and is electrically connected to the control cabinet of the multi-passage warehouse. The device includes a bolt 3, a time delay relay 4, a reset indicator light 5, and an electromagnetic door lock 6.

[0021] The latch 3 includes a latch base 31, a latch rod 32, and a latch lock hole 33. The latch base 31 is made of metal and has a groove for the latch rod 32. It is fixed to the single door 1 by fasteners. The latch rod 32 includes a plate-shaped latch rod made of metal, which is slidably disposed on the groove of the latch base 31 and moves horizontally along the groove on the latch base 31. The latch rod 32 is provided with a rigid pressure block 321 made of polymer insulating material and a plastic handle 322. The latch lock hole 33 is provided on the door frame 2. A through-beam photoelectric switch is provided in the latch lock hole 33 to detect whether the latch rod 32 is inserted into place. The through-beam photoelectric switch is electrically connected to the electromagnetic door lock 6.

[0022] The time delay relay 4, the reset indicator 5, and the electromagnetic door lock 6 are arranged sequentially from top to bottom on the door frame 2, with the time delay relay 4 resting against the pin base 31.

[0023] The time-delay relay 4 includes a lever switch module 41 and a time-delay relay module 42. The lever 411 is mounted on the lever switch module 41, and the lever switch module 41 and the time-delay relay module 42 are connected together. The time-delay relay 4 is electrically connected to the reset switch of the multi-passage warehouse control cabinet. The time-delay relay 4 can receive the reset signal sent by the control cabinet and achieve a preset time delay unlocking control through the time-delay relay module 42. The preset delay time can be adjusted according to the shutdown response time of the multi-passage warehouse equipment, such as 5 seconds or 8 seconds.

[0024] The reset indicator light 5 and the electromagnetic door lock 6 are electrically connected to the reset switch of the multi-passage warehouse control cabinet. When the control cabinet sends a reset signal, the reset indicator light 5 illuminates, indicating to maintenance personnel that the equipment has entered a safe reset state and that the electromagnetic door lock 6 can be opened. When the equipment has not completed the reset, the reset indicator light 5 remains off, serving as a safety warning.

[0025] The electromagnetic door lock 6 is a push-pull electromagnet with an operating voltage of 24V.

[0026] The working principle of this utility model is as follows: (This is a multi-access warehouse safety linkage delayed unlocking protection device.)

[0027] Locked State: When the multi-passage warehouse maintenance entrance and exit are closed, maintenance personnel push the latch rod 32 to insert it into the latch lock hole 33. At this time, the pressure block 321 on the latch rod 32 presses the pressure rod 411 of the time delay relay 4, triggering the pressure rod switch module 41 to close. Simultaneously, the latch rod 32 blocks the optical path of the through-beam photoelectric switch in the latch lock hole 33. The photoelectric switch outputs a high-level signal, controlling the electromagnetic door lock 6 to remain in the locked state. At this time, the reset indicator light 5 goes out, and the multi-passage warehouse equipment operates normally.

[0028] Delayed unlocking: When equipment maintenance or repair is required, the maintenance personnel grasp the handle 322 of the latch 32, pull the latch 32 open, and the through-beam photoelectric switch detects no obstruction. Simultaneously, the pressure lever 411 of the time-delay relay 4 loses pressure, triggering the pressure lever switch module 41 to switch. The time-delay relay module 42 sends a signal to activate the multi-passage warehouse reset switch, controlling the equipment inside the multi-passage warehouse to reset and stop working. After a certain period of time, the equipment in the multi-passage warehouse has completed the reset. The time-delay relay 4 sends a control signal to the reset indicator light 5 and the electromagnetic door lock 6 through the multi-passage warehouse reset switch, causing the reset indicator light 5 to light up and the electromagnetic door lock 6 to unlock. The maintenance personnel can then open the electromagnetic door lock 6 and then open the single door 1 to enter the multi-passage warehouse to perform maintenance or repair work.

[0029] Door closing and reset: After maintenance, close the single door 1, insert the pin 32, press the pressure block 321 again to press the pressure rod 411, the light path of the through-beam photoelectric switch is blocked, the electromagnetic door lock 6 is locked, the control cabinet reset switch of the multi-passage warehouse is automatically disconnected, the reset indicator light 6 is turned off, and the multi-passage warehouse equipment returns to normal operation.

[0030] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
