Description

Technical Field

[0001] The utility model relates to the technical field of fireproof doors, in particular to a protective locking mechanism and a detection device. Background Art

[0002] At present, many fire doors between equipment rooms of production units and home entrance doors use door locks and access control double locks to control personnel access. Most access control systems have access control lock identification prompts, such as indicator lights and display screens showing that the door has been locked by access control. In this prompt mechanism, it is not easy to find that the door lock is damaged or not locked in place. During the use of access control, if the access control system fails or loses power, the fire doors between equipment rooms of production units or home entrance doors will lose their function of controlling safety and become useless. Especially for some outdoor or more important production areas, such as outdoor production areas, if the door lock is damaged or not locked in place, when the access control fails, in case of rainy or windy weather, water or other foreign objects entering the equipment room will bring hidden dangers to production safety. For example, for the fire door of the wind tunnel of a hydropower station generator, if the door lock is not locked in place or is damaged, the fire door, which is closed only by the electromagnetic suction force of the access control, will be subjected to long-term and extremely high positive pressure in the wind tunnel. The sealing performance of the fire door will decrease, and the positive pressure wind in the wind tunnel will flow out along the door gap. If this continues for a long time, the protective door will be deformed or the access control suction mechanism will be damaged. If the access control is damaged at this time, the wind tunnel fire door will be blown open by the wind pressure. In this case, the uncontrollability of personnel or the entry of foreign objects will greatly affect the safety of power production.

[0003] In the event that the mechanical door lock is not locked because the interior cannot be directly observed and the electronic door lock is in a system failure, the failure of the fire door anti-locking will result in serious safety hazards. Utility Model Content

The internal arrangement of the plug-in 102 is the same as that of a conventional door lock structure, and a protective groove 102a is provided at the inclined end of the plug-in 102. The plug-in 102 is arranged as a plane away from the inclined end to better achieve the locking effect of the door, so a protective groove 102a is provided at the inclined end of the plug-in 102.

[0035] Furthermore, the protective component 103 includes an adjustment shell 103a arranged to cooperate with the housing 101, and a first through hole 103a-1 is penetrated on one side of the adjustment shell 103a. A protective rod 103b is arranged inside the first through hole 103a-1. The protective rod 103b is arranged to cooperate with the protective groove 102a. When the plug-in 102 on the door lock is locked, it is observed whether the protective rod 103b falls down after being lifted up. When the plug-in 102 passes through the protective rod 103b, the protective rod 103b is driven to rise. When the plug-in 102 is completely locked and released, the plug-in 102 The protective groove 102a on the upper part is displaced to the position of the protective rod 103b so that the protective rod 103b can be inserted into the protective groove 102a, and the protective rod 103b can be displaced in the vertical direction inside the first through hole 103a-1. The protective rod 103b is provided with a clamping groove 103b-1, and there are several groups of clamping grooves 103b-1.

The second baffle 103b-3 is arranged inside the adjusting shell 103a. The cross-sections of the first baffle 103b-2 and the second baffle 103b-3 are larger than the cross-section of the first through hole 103a-1. The protective rod 103b is displaced at a distance between the first baffle 103b-2 and the second baffle 103b-3. The cross-section area of ​​the first baffle 103b-2 and the second baffle 103b-3 is set larger than the cross-section area of ​​the first through hole 103a-1, so that the protective rod 103b will not be out of cooperation with the first through hole 103a-1.

[0037] Furthermore, the adjusting component 200 includes a fixed column 201 arranged on the side of the adjusting shell 103a close to the first baffle 103b-2, the fixed column 201 is fixedly connected to the adjusting shell 103a, and a second through hole 201a is provided on the side of the fixing column 201 close to the clamping groove 103b-1, and several groups are arranged on one side of the second through hole 201a to cooperate with the clamping groove 103b-1.

[0038] Furthermore, a fixing plate 201b is provided on one side of the fixing column 201 near the second through hole 201a, and the fixing plate 201b is arranged to cooperate with the second through hole 201a, and the fixing plate 201b is arranged to be fixedly connected to the fixing column 201, and a displacement groove 201b-1 is provided in the fixing plate 201b, and the interior of the displacement groove 201b-1 is arranged to be an inclined surface, and the inclined surface in the displacement groove 201b-1 is arranged to have an inner cross section larger than the outer cross section, and at the same time, a clamping block 201b-2 is arranged on one side of the interior of the displacement groove 201b-1 to be in close contact with the displacement groove 201b-1, so that the clamping block 201b-2 will not be out of cooperation with the displacement groove 201b-1 when it is displaced in the displacement groove 201b-1, and the displacement groove 201b-2 1b-1 is tilted, a clamping block 201b-2 is arranged in the displacement groove 201b-1, the clamping block 201b-2 is arranged on the side close to the displacement groove 201b-1 and is slidably connected to the displacement groove 201b-1, the clamping block 201b-2 is arranged on the side close to the clamping groove 103b-1 and is matched with the clamping groove 103b-1, an elastic member 201b-3 is fixed on one side of the displacement groove 201b-1, the elastic member 201b-3 can make the clamping block 201b-2 return to its original position after being displaced toward the side of the second through hole 201a, the elastic member 201b-3 is arranged on the side close to the clamping block 201b-2 and is matched with the clamping block 201b-2, and the side of the clamping block 201b-2 away from the clamping groove 103b-1 is arranged as an inclined surface.

[0039] Furthermore, the adjusting component 200 further includes a rotation groove 202, which is arranged on the surface of the adjusting shell 103a, and a rotating member 202a is arranged in the rotation groove 202. When the rotating member 202a rotates in the rotation groove 202, it will not be out of engagement, so that the rotating member 202a can rotate in the rotation groove 202, and the rotating member 202a is arranged to rotate with the rotation groove 202. A push block 202a-1 is fixed inside the rotating member 202a, and the push block 202a-1 is arranged to be engaged with the clamping block 20 1b-2 is matched with the inclined end, and the push block 202a-1 has several groups. The push block 202a-1 is fixed on the side wall of the rotating member 202a, so that when the rotating member 202a is rotated, the push block 202a-1 can be driven to move. When the push block 202a-1 moves to the inclined end of the clamping block 201b-2, the clamping block 201b-2 can be pushed through the second through hole 201a and the clamping groove 103b-1 and then cooperate with the protective rod 103b, so that the protective rod 103b can no longer move up and down. At this time, the protective rod 103b.

[0040] In summary, when the fire door is closed, the plug-in 102 on the door cooperates with the protective component 103 on the door frame, and the plug-in 102 enters the interior of the adjustment shell 103a. At this time, the plug-in 102 is subjected to the elastic force of the lock body. It should be noted that the connection between the interior of the housing 101 and the plug-in 102 is arranged in the same manner as the interior of a conventional door lock, so that the plug-in 102 can be reset by the elastic force of the lock body and enter the interior of the adjustment shell 103a. At this time, the flat end of the plug-in 102 contacts the adjustment shell 103a to form a lock. When the plug-in 102 is reset, the plug-in 102 The protective rod 103b plug-in contacts and squeezes the protective rod 103b. When the protective groove 102a on the plug-in 102 moves to the vertical position of the protective rod 103b, the protective rod 103b is inserted into the protective groove 102a through the handle 103b-4, and then the rotating member 202a is rotated to make the push block 202a-1 on the inner side wall of the rotating member 202a squeeze the inclined surface of the clamping block 201b-2, so that the clamping block 201b-2 passes through the second through hole 201a and the clamping groove 103b-1 and then cooperates with the protective rod 103b to form a locking.

[0041] When unlocking is required, the pushing block 202a-1 is disengaged from the inclined surface of the clamping block 201b-2 by rotating the rotating member 202a. At this time, the clamping block 201b-2 is reset by the elastic force of the elastic member 201b-3 inside the displacement groove 201b-1, so that the clamping block 201b-2 passes through the clamping groove 103b-1 and the second through hole 201a and completely disengages from the protective rod 103b. Then, the handle 103b-4 is pulled to drive the protective column 103b to unlock the fire door.

[0042] Example 2

[0043] Reference Figure 1 to Figure 8, which is the second embodiment of the utility model. Different from the previous embodiment, it also includes a locking assembly 300 including a block 301 fixedly connected to the rotating member 202a, a locking member 302 is provided on one side of the adjusting shell 103a to cooperate with the block 301, a telescopic groove 302a is provided on the side of the locking member 302 close to the block 301, a slide rail 302a-1 is provided on one side of the telescopic groove 302a, an abutment block 302b is provided inside the telescopic groove 302a, the abutment block 302b is provided to cooperate with the block 301, one side of the abutment block 302b is provided as an inclined surface, a displacement plate 302b-1 is fixed on the side of the abutment block 302b close to the slide rail 302a-1, and the displacement plate 302b-1 is provided to be slidably connected to the slide rail 302a-1.

[0044] Specifically, the block 301 fixed on the rotating member 202a rotates with the rotation of the rotating member 202a, and the locking member 302 arranged on one side of the rotating member 202a has a telescopic groove 302a close to the side of the block 301. The abutment block 302b in the telescopic groove 302a performs vertical displacement in the telescopic groove 302a, and a sliding rail 302a-1 is provided on one side of the telescopic groove 302a to cooperate with the displacement plate 302b-1 on the abutment block 302b, thereby preventing the abutment block 302b from being separated from the telescopic groove 302a.

[0045] In summary, in the process of rotating the rotating member 202a, the blocking block 301 is driven to cooperate with the abutment block 302b. The principle is the same as that of Example 1. When the blocking block 301 rotates to contact the inclined surface of the abutment block 302b, the abutment block 302b is retracted into the telescopic groove 302a until the blocking block 301 passes through the abutment block 302b. The abutment block 302b automatically falls down due to the action of gravity, so that the plane end of the abutment block 302b contacts the abutment block 302b to form a lock. At this time, the protective rod 103b is locked inside the protective groove 102a, and the pushing block 202a-1 in the rotating member 202a contacts the inclined surface end of the clamping block 201b-2 and squeezes the clamping block 201b-2 to lock the protective rod 103b, thereby preventing the movement of the protective rod 103b.

[0046] When unlocking is required, the staff moves the abutment block 302b into the telescopic slot 302a to rotate the clamping block 301 in the opposite direction of the locking process, so that the clamping block 301 passes through the abutment block 201b-2, thereby unlocking.

[0047] Example 3

[0048] Reference Figure 1 to Figure 9 , which is the third embodiment of the utility model, and further provides a detection device, including a detection module 400, which includes a door lock identification alarm, a self-reset switch RST-SW, an infrared sensor switch K1, a fuse protection switch SB, a plurality of indicator lights and an alarm buzzer arranged inside the housing 101.

[0049] Furthermore, the detection modules 400 are electrically connected to each other.

[0050] Specific:

[0051] a. Access control and door locks are all locked: At this time, relays KA2 and KA3 are energized, the normally open nodes KA2 and KA3 in circuit 4 are closed, and the green indicator light is on.

[0052] b. Access control or door lock single locking: If only the access control is locked or the door lock is locked, then in the parallel circuit of circuit 5, only the normally open node KA2 is closed, the normally closed node KA3 is closed, and the circuit is energized; or the normally open node KA3 is closed, the normally closed node KA2 is closed, and the yellow indicator light is on, indicating that the access control or door lock is faulty.

[0053] c. When the access control and door lock full lock identification warning device has power, the access control and door locks are both unlocked: at this time, relays KA2 and KA3 are not energized, the normally closed nodes of the two relays are closed, and the normally open node of relay KA1 is energized and closed. At this time, the red indicator light is on, indicating that the access control or door lock is faulty or the door is open.

[0054] d. The power supply of the access control and door lock identification warning device is lost: In this case, the device may be short-circuited, causing the fuse protection switch SB to trip or the lower end of the device power fuse protection switch SB to be open, and the relay KA1 normally closed node is closed without power. Circuit 5 is at the upper end of the fuse protection switch SB at the upper end of the device power supply, and the main power supply has power. At this time, the buzzer alarm indicates that there is a fault in the device circuit.

[0055] e. Main power failure: At this time, all circuits have no power, all indicator lights are off, and the buzzer loses power. Because the main power supply and the access control system are taken from the same main power supply, it means that the access control system circuit has a power failure.

[0056] In summary, for the fire doors of the wind tunnel of the generator of the hydropower station, when the red indicator light of the access control and door lock full lock identification warning device is on, it reminds the relevant staff of the power station that the fire door is not closed at this time, and reminds the relevant staff to remember to close the fire door in time when entering and exiting; when the green indicator light of the access control and door lock full lock identification warning device is on, it informs the relevant staff that the fire door is closed normally; when the yellow indicator light of the access control and door lock full lock identification warning device is on, at this time only the access control or door lock of the fire door is locked, reminding the relevant staff that the access control is faulty, the door lock is damaged or the door lock is not locked in place, and warns the relevant staff to try to close the fire door again or check whether the access control is faulty or the door lock is damaged; when the buzzer sounds, it reminds the relevant staff that the access control and door lock full lock identification warning device is faulty and needs to be checked in time; when all the indicator lights are off and the buzzer does not work, it reminds the relevant staff that the main power supply of the access control is faulty and needs to be dealt with immediately to eliminate the hidden danger.
