[0046] First Embodiment

[0047] The present embodiment provides a self-protection method for a firefighting box, including:

[0048] providing a firefighting box mechanism G, wherein the firefighting box may be of a box structure, or other types of structure, and the firefighting box can be installed indoors;

[0049] providing a fire monitoring structure on the firefighting box mechanism G to monitor whether a fire occurs, wherein the fire monitoring structure may be various fire sensors, such as smoke sensors or temperature sensors or photoelectric sensors, capable of monitoring whether a fire occurs in the surrounding environment;

[0050] providing a self-protection structure associated with the fire monitoring structure on the firefighting box mechanism G, wherein the self-protection structure can protect the firefighting box mechanism G and is mainly provided outside the firefighting box mechanism

G, and in the present embodiment, the firefighting box mechanism G is a pipe capable of spraying water;

[0051] obtaining a monitoring result via the fire monitoring structure, wherein there are two monitoring results obtained by the fire monitoring structure: one is no fire occurs in the environment, and the other is a fire occurs in the environment; and

[0052] determining whether to activate the self-protection structure according to the monitoring result, wherein the fire monitoring structure can transmit the monitoring result to the self-protection structure, and when the monitoring result shows that no fire occurs in the environment, the self-protection structure remains closed, but when the monitoring result shows that a fire occurs in the environment, the self-protection structure is activated. The self-protection structure can avoid damage to the firefighting box mechanism G in case of fire.

[0053] Specifically, the obtaining a monitoring result via the fire monitoring structure includes that the fire monitoring structure is capable of monitoring the environment of the firefighting box and determining whether a fire occurs.

[0054] Further, the self-protection structure is capable of avoiding the firefighting box mechanism G from being damaged in case of fire, since the self-protection structure can avoid the fire from approaching the firefighting box, avoid the firefighting box from being damaged by high temperature, and avoid the firefighting box from being heated to over high temperature.

[0055] Second Embodiment

[0056] With reference to FIG. 2, the present embodiment differs from the first embodiment in that: the present embodiment further provides a firefighting box. The firefighting box includes the firefighting box mechanism G in the self-protection method for a firefighting box in the previous embodiment, the firefighting box mechanism G being provided with a water supply pipe 101; further including a receiving mechanism 200, the receiving mechanism including a housing 201 arranged inside the firefighting box mechanism G and an inner cylinder 202 arranged inside the housing 201; and a telescopic mechanism 300, including a telescopic pipe fitting 301 slidably arranged on the inner cylinder 202, a reel seat member 302 slidably connected with the telescopic pipe fitting 301, a hose reel rotatably arranged on the reel seat member 302, and a locking member 303 arranged on the housing 201. The locking member 303 is capable of locking the telescopic pipe fitting 301, the reel seat member 302 and the hose reel to the inside of the housing 201.

[0057] When the pipe 1s retracted, the telescopic pipe fitting 301 can be retracted to the outer side of the inner cylinder 202, the reel seat member 302 can be retracted to the inner side of the telescopic pipe fitting 301, and the locking member 303 can lock the telescopic mechanism 300 in the retracted state to the inner side of the housing 201. When it is required to use the pipe body wrapped outside the hose reel, it only needs to unlock the locking member 303, the telescopic pipe fitting 301, the reel seat member 302, and the hose reel can extend out from the inside of the housing 201, so that the operator can quickly take the pipe body outside the hose reel.

[0058] Specifically, the outer side of the inner cylinder 202 is provided with a first sliding groove 202a, the inner side of the telescopic pipe fitting 301 is fixed with a first sliding block 301a, and when the telescopic pipe fitting 301 is sleeved outside the inner cylinder 202, the first sliding block 301a is slidably clamped inside the first sliding groove 202a; the outer side of the telescopic pipe fitting 301 is provided with a second sliding groove 301b, the inner side of the reel seat member 302 is fixed with a second sliding block 303a, and when the reel seat member 302 is sleeved outside the telescopic pipe fitting 301, the second sliding block 303a is slidably clamped inside the second sliding groove 301b.

[0059] The first sliding groove 202a is parallel to the extension direction of the inner cylinder 202, and the second sliding groove 301b is parallel to the extension direction of the telescopic pipe fitting 301. The first sliding block 301a is slidably clamped inside the first sliding groove 202a to prevent the telescopic pipe fitting 301 from rotating outside the first sliding groove 202a. The second sliding block 303a is slidably clamped inside the second sliding groove 301b to prevent the reel seat member 302 from rotating outside the telescopic pipe fitting 301. The telescopic pipe fitting 301 can slide relative to the inner cylinder 202, and the real seat member 302 can slide relative to the telescopic pipe fitting 301.

[0060] The locking member 303 includes a guide rod 304a slidably connected to the housing

201, a cylinder 304b connected to the guide rod 304a, a locking head 304c located at an end of the cylinder 304b, and a first spring 304d abutting against the cylinder 304b. The telescopic pipe fitting 301 1s further provided with a locking hole 301c, and when the locking head 304c is located inside the locking hole 301c, the telescopic pipe fitting 301 can be locked.

[0061] The elastic force of the first spring 304d can push the cylinder 304b so that the cylinder 304b is subjected to a thrust towards the inner cylinder 202. When the position of the locking head 304c corresponds to the position of the locking hole 301c under the push of the first spring 304d, the locking head 304c can be pushed into the locking hole 301c during the movement and retraction of the telescopic pipe fitting 301 towards the inner side of the housing 201, so as to position the telescopic pipe fitting 301 and lock the telescopic pipe fitting 301 to the inner side of the housing 201.

[0062] One side, facing towards the telescopic pipe fitting 301, of the locking head 304c is a pressure-bearing arc surface. When the telescopic pipe fitting 301 moves toward the inner side of the housing 201, the telescopic pipe fitting 301 can push the locking head 304c when the telescopic pipe fitting 301 can contact the pressure-bearing arc surface. The locking head 304c pushes the cylinder 304b to press the first spring 304d. When the position of the locking head 304c corresponds to the position of the locking hole 301c, the cylinder 304b can be pushed to drive the locking head 304c into the inner side of the locking hole 301c to lock the position of the telescopic pipe fitting 301, under the elastic force of the first spring 304d.

[0063] The side wall of the telescopic pipe fitting 301 has a side cavity 301d, and the telescopic mechanism 300 further includes an elastic limiting member 305 arranged inside the side cavity 301d. The elastic limiting member 305 includes an embedded sheet 305a arranged inside the side cavity 301d; an embedded column 305b slidably arranged in the side cavity 301d; a second spring 305¢, arranged inside the side cavity 301d and abutting against the embedded column 305b; an upper limiting block 305d arranged at one end of the embedded column 305b; and a lower abutting block 305e arranged at the other end of the embedded column 305b. The outer side of the inner cylinder 202 is further provided with a side groove

N, the side groove N has a high level end N1 and a low level end N2, and a lifting section N3 between the high level end N1 and the low level end N2.

[0064] In order to position the telescopic pipe fitting 301 and the real seat member 302 during the retraction of the telescopic pipe fitting 301 and the real seat member 302, the number of the embedded sheets 30Sa is two, and the two embedded sheets are respectively located at two ends of the side cavity 301d. When the telescopic mechanism 300 is in an expanded state, the lower abutting block 305e is located at the lower level end N2, and the lower abutting block 305e abuts against the lower level end N2 under the pushing of the second spring 305c, and the upper limiting block 305d retracts to the inner side of the embedded sheet 305a and the side cavity 301d, so that the reel seat member 302 can move along the telescopic pipe fitting 301.

[0065] A third spring 306 is further sleeved outside the inner cylinder 202, and the third spring 306 abuts against the telescopic pipe fitting 301.

[0066] In the retracted state, the telescopic pipe fitting 301 abuts against the third spring 306.

When the box needs to be used, it is only required to unlock the locking member 303, so that the telescopic pipe fitting 301 can be pushed out from the inner side of the housing 201 under the push of the third spring 306.

[0067] The remaining structures are the same as those in the first embodiment.

[0068] The operation process is as follows. When the pipe is retracted, the telescopic pipe fitting 301 can be retracted to the outer side of the inner cylinder 202, the reel seat member 302 can be retracted to the inner side of the telescopic pipe fitting 301, and the locking member 303 can lock the telescopic mechanism 300 in the retracted state to the inner side of the housing 201. When it is required to use the pipe body wrapped outside the hose reel, it only needs to unlock the locking member 303, the telescopic pipe fitting 301, the reel seat member 302, and the hose reel can extend out from the inside of the housing 201, so that the operator can quickly take the pipe body outside the hose reel.

[0069] When the telescopic mechanism 300 needs to be retracted after use, the operator can directly push the reel seat member 302, the reel seat member 302 first moves along the telescopic pipe fitting 301, until the reel seat member 302 and the telescopic pipe fitting 301 contract outside, the reel seat member 302 passes over the upper limiting block 305d, and the reel seat member 302 abuts against an end of the telescopic pipe fitting 301.

[0070] At this time, the reel seat member 302 is further pushed, and the reel seat member 302 can push the telescopic pipe fitting 301 to move towards the inner side of the housing 201, thereby driving the elastic limiting member 305 to move. In this process, the lower abutting block 305e moves from the lower level end N2 through the lifting section N3 to the upper level end NI, and the upper level end N1 has a shallower groove compared to the lower level end N2, so that the lower abutting block 305e can be pushed, the lower abutting block 305e pushes the embedded column 305b against the second spring 305c, so that the upper limiting block 305d protrudes out from the inner side of the side cavity 301d. The reel seat member 302 is limited between the upper limiting block 305d and one end of the telescopic pipe fitting 301, and the outer reel seat member 302 and the telescopic pipe fitting 301 are contracted and locked.

[0071] With the continuous movement of the telescopic pipe fitting 301, the position of the locking hole 301c and the position of the locking block are locked, and the locking block enters the inner side of the locking hole 301c, so that the telescopic pipe fitting 301 can be positioned on the inner side of the housing 201. According to the technical solution above, when it is retracted, it is only required to push the real seat member 302 to finish the contraction of the telescopic mechanism 300, with the telescopic mechanism 300 being positioned on the inner side of the housing 201.

[0072] Third Embodiment

[0073] With reference to FIG. 2, the present embodiment differs from the previous embodiment in that: The firefighting box mechanism G further includes a protective pipe 102 connected to the water supply pipe 101; it further includes a monitoring mechanism 400, the monitoring mechanism including a fire monitor 401 arranged on the firefighting box mechanism G, and a position reminder alarm 402 electrically connected to the fire monitor 401; and a connecting valve pipe 500, including a communicating pipe body 501 connecting the water supply pipe 101 with the protective pipe 102, and a switch assembly 502 capable of closing or opening the communicating pipe body 501; the switch assembly 502 is controlled by the fire monitor 401.

[0074] The fire monitor 401 may be a smoke sensor or other fire monitoring sensor. When a fire is detected, the fire monitor 401 transmits a signal to the alarm 402 and the switch assembly 502, the alarm 402 performs an alarm operation, and the switch assembly 502 opens the communicating pipe body 501, so that the water inside the water supply pipe 101 can enter the protective pipe 102, and is finally ejected out from the protective pipe 102. The alarm 402 can remind the firefighter of the position of the firefighting box. The protective pipe 102 can eject water columns around the firefighting box, so as to avoid the fire from contacting the firefighting box, and prevent the firefighting box from being heated to an over high temperature and being inaccessible.

[0075] Specifically, the switch assembly 502 includes a switch compartment 502a, the switch compartment having an inlet 502a-1 connected to the water supply pipe 101 and an outlet 502a-2 connected to the communicating pipe body 501; a plug member 502b, the plug member including a sliding column 502b-1 slidably arranged on the switch compartment 502a, a load-bearing member 502b-2 arranged at one end of the sliding column 502b-1, and a plug 502b-3 arranged at the other end of the load-bearing member 502b-2.

[0076] The switch compartment 502a is used for communicating the water supply pipe 101 with the communicating pipe body 501. When the plug member 502d plugs the water inlet 502a-1, the water supply pipe 101 is disconnected from the communicating pipe body 501.

When the sliding column 502b-1 moves away from the water inlet 502a-1, the plug 502b-3 can depart from the water inlet 502a-1, and the water inlet 502a-1 is no longer blocked. Under the action of water pressure, the water inside the water supply pipe 101 reaches the inner side of the switch compartment 502a through the water inlet 502a-1, reaches the inner side of the communicating pipe body 501 through the outlet 502a-2, and is finally discharged from the protective pipe 102 to spray around the firefighting box to protect the firefighting box from being heated to over high temperature.

[0077] The operation process is as follows. When a fire is detected, the fire monitor 401 transmits a signal to the alarm 402 and the switch assembly 502, the alarm 402 performs an alarm operation, and the switch assembly 502 opens the communicating pipe body 501, so that the water inside the water supply pipe 101 can enter the protective pipe 102, and is finally ejected out from the protective pipe 102. The alarm 402 can remind the firefighter of the position of the firefighting box. The protective pipe 102 can eject water columns around the firefighting box, so as to avoid the fire from contacting the firefighting box, and prevent the firefighting box from being heated to an over high temperature and being inaccessible.

[0078] The water supply pipe 101 is fixed to a fire pipe body 102a on the firefighting box mechanism 100, and to a water supply port 102b on the fire pipe body 102a. The water supply port 102b is used for supplying water to the external water pipe for extinguishing a fire. À switch valve is provided at the water supply port 102b, and the water supply port 102b can be opened or closed by the switch valve. Under a normal state, the switch valve is closed, and the water inside the fire pipe body 102a cannot be discharged from the water supply port 102b.

When it is required to extinguish a fire, the switch valve can be opened, so that the water inside the fire pipe body 102a can be discharged from the water supply port 102b. 10079] Specifically, it further includes an actuating mechanism 600. The actuating mechanism includes a first elastic member 601 which is sleeved outside the water supply port 102b; a rotating assembly 602, which is slidably arranged outside the water supply port 102b and abuts against the first elastic member 601; a transmission assembly 603 arranged between the rotating assembly 602 and the load-bearing member 502b-2; and a trigger mechanism 700.

The trigger mechanism 700 includes a positioning ring 701 fixed to the outer side of the water supply port 102b; a clamping assembly 702 slidably arranged on the positioning ring 701; and a positioning assembly 703, which is fixed to the positioning ring 701 and can lock the clamping assembly 702.

[0080] In a normal state, the positioning assembly 703 can lock the position of the clamping assembly 702, so that the clamping assembly 702 can abut against and lock the rotating assembly 602, preventing the rotating assembly 602 from rotating, and the rotating assembly 602 under abutment presses the first elastic member 601 so that the first elastic member 601 is deformed. The positioning assembly 703 is electrically connected to the fire monitor 401,

When the fire monitor 401 detects a fire, an electrical signal is transmitted to the positioning assembly 703, the positioning assembly 703 no longer locks the position of the clamping assembly 702, the elasticity of the first elastic member 601 pushes the rotating assembly 602, and the rotating assembly 602 pushes the clamping assembly 702 to move. The rotating assembly 602 contacts the positioning ring 701 during the movement, and the positioning ring 701 prevents the rotating assembly 602 from moving any more. The rotating assembly 602 pushes the clamping assembly 702 to move further to disengage from the rotating assembly 602.

[0081] Further, the rotating assembly 602 includes an outer ring body 602c and an inner ring body 602a which are rotatably connected. The inner ring body 602a is slidably sleeved outside the water supply port 102b. The inner ring body 602a is fixed with an elastic arc rail 602b, the outer ring body 602c is fixed with a sleeve block 602d, and the sleeve block 602d is connected to the elastic arc rail 602b. The transmission assembly 603 includes a swing bar

603a arranged on the outer ring body 602c, a cross bar 603b arranged at an end of the swing bar 603a, and a pull pin 603c arranged on the cross bar 603b. The pull pin 603c is connected to the load-bearing member 502b-2, and a connection through groove is provided on the pull pin 603c. The load-bearing member 502b-2 is a column, and the pull pin 603c is sleeved outside the load-bearing member 502b-2 through the connection through groove.

[0082] The inner ring body 602a is coaxial with the outer ring body 602c. In the natural state, the clamping assembly 702 abuts against the outer ring body 602c to lock the position of the outer ring body 602c, and the elastic force of the elastic arc rail 602b is in a state of abutting against the sleeve block 602d. When the positioning assembly 703 no longer locks the position of the clamping assembly 702, the elasticity of the first elastic member 601 pushes the rotating assembly 602, and the rotating assembly 602 pushes the clamping assembly 702 to move. The rotating assembly 602 will contact the positioning ring 701 in the process of moving, and the positioning ring 701 prevents the rotating assembly 602 from further movement. The thrust of the rotating assembly 602 to the clamping assembly 702 can push the clamping assembly 702 to move further to disengage from the rotating assembly 602. At this time, the position of the outer ring body 602c is no longer locked by the clamping assembly 702, and driven by the elastic arc rail 602b, it can push the sleeve block 602d, so that the sleeve block 602d drives the outer ring body 602c to rotate, thereby driving the swing bar 603a to swing. The swing bar 603a drives the pull pin 603c to move, thereby pulling the load-bearing member 502b-2. Therefore, the sliding column 502b-1 drives the plug 502b-3 to move away from the water inlet 502a-1, so that the plug 502b-3 no longer blocks the water inlet 502a-1, and the water inside the fire pipe body 102a can reach the communicating pipe body 501, and finally reach the protective pipe 102 through the communicating pipe body 501 and spray out, so as to protect the firefighting box.

[0083] Further, the positioning ring 701 includes a placing ring body 701a fixed to the water supply port 102b, and a coaxial groove 701b defined on the placing ring body 701a. The clamping assembly 702 includes a sliding rod 702a slidably arranged on the coaxial groove 701b, a snap fastener 702b arranged at one end, close to the rotating assembly 602, of the sliding rod 702a, and a positioning hole 702c defined on the sliding rod 702a. The positioning assembly 703 includes a placing table 703a fixed to the placing ring body 701a, a movable lock column 703b slidably arranged on the placing table 703a, an electromagnet 703d arranged at an end of the placing table 703a, and a second elastic member 703c that abuts against the movable lock column 703b. The outer ring body 602c is provided with a snap tooth set 602e.

[0084] The placing ring body 701a is fixed on the water supply port 102b and cannot move.

The coaxial groove 701b penetrates the placing ring body 70la and is arc-shaped, and is coaxial with the placing ring body 701a, the inner ring body 602a, and the outer ring body 602c. The two groove walls of the coaxial groove 701b are arc-shaped. The two side walls of the sliding rod 702a are also arc-shaped, and fit the two groove walls of the coaxial groove 701b, which can avoid the problem that the sliding rod 702a rotates with respect to the coaxial groove 701b, so that one end of the sliding rod 702a installed with the snap fastener 702b is always aligned with the outer ring body 602c. In the natural state, the snap fastener 702b is engaged with the snap tooth set 602e, so that the outer ring body 602c can be positioned and prevented from rotating.

[0085] Further, the elastic arc rail 602b includes a supporting block 602b-1 fixed to the outer side of the inner ring body 602a, an arc-shaped column 602b-2 provided on the supporting block 602b-1, and a third elastic member 602b-3 sleeved outside the arc-shaped column 602b-2. The sleeve block 602d is slidably sleeved outside the arc-shaped column 602b-2 and abuts against the third elastic member 602b-3.

[0086] The arc-shaped column 602b-2, the inner ring body 602a, the outer ring body 602c, and the coaxial groove 701b are coaxial with each other. In the natural state, the movable lock column 703b locks the position of the sliding rod 702a, the sliding rod 702a abuts against the outer ring body 602c to press the first elastic member 601, and the snap fastener 702b engages with the snap tooth set 602e, so that the outer ring body 602c cannot rotate. When the snap fastener 702b is disengaged from the snap tooth set 602e, the third elastic member 602b-3 can push the sleeve block 602d, so that the sleeve block 602d moves outside the arc-shaped column 602b-2 and drives the outer ring body 602c to rotate in a first direction.

[0087] The fire monitor 401 and the electromagnet 703d are electrically connected via an intermediate relay, and the fire monitor 401 can transmit an electrical signal to the intermediate relay so that the intermediate relay supplies power to the electromagnet 703d.

[0088] The operation process is as follows. In the natural state, the electromagnet 703d is in a power-off state and cannot attract the movable lock column 703b. Under the elastic force of the second elastic member 703c, the end of the movable lock column 703b extends to the inner side of the positioning hole 702c, so as to position the sliding rod 702a and avoid movement of the sliding rod 702a, so that the sliding rod 702a can keep abutting against the outer ring body 602c, and the snap fastener can engage the snap tooth set 602e, achieving a positioning effect on the outer ring body 602c. When a fire occurs, the fire monitor 401 detects the occurrence of the fire, transmits an electrical signal to the electromagnet 703d, and supplies power to the electromagnet 703d, the electromagnet 703d attracts the movable lock column 703b, and the movable lock column 703b moves towards the electromagnet 703d to press the second elastic member 703c, so that an end of the movable lock column 703b 1s detached from the inner side of the positioning hole 702c. At this time, the position of the sliding rod 702a is no longer fixed, and the elastic force of the first elastic member 601 pushes the rotating assembly 602, so that the inner ring body 602a and the outer ring body 602c move synchronously, pushing the sliding rod 702a to move. When the inner ring body 602a and the outer ring body 602c contact the placing ring body 701a, they will be stopped and cannot move further. The thrust on the sliding rod 702a can push the sliding rod 702a to continue moving, so that the snap fastener 702b is disengaged from the snap tooth set 602e, and the outer ring body 602c is no longer locked. Driven by the elastic arc rail 602b, the sleeve block 602d drives the outer ring body 602c to rotate in the first direction, so that the swing bar 603a is driven to swing, the load-bearing member 502b-2 is pulled, and the sliding column 502b-1 drives the plug 502b-3 to move away from the water inlet 502a-1. Therefore, the plug 502b-3 no longer blocks the water inlet 502a-1, so that the water inside the fire pipe body 102a can reach the communicating pipe body 501, and finally reach the protective pipe 102 through the communicating pipe body 501 and spray out, so as to protect the firefighting box.

[0089] It further includes a connecting water pipe 800. The connecting water pipe 800 includes a connecting head 801 and a pressing column 802 arranged on the connecting head 801. The clamping assembly 702 further includes a synchronization member 702d arranged at an end, away from the snap fastener 702b, of the sliding rod 702a.

[0090] In the present embodiment, the water supply port 102b is circular, and the connecting head 801 is also circular. A first snapping protrusion 102b-1 is provided on the inner side of the water supply port 102b, and a second snapping protrusion 801a is provided on the outer side of the connecting head 801. When the connecting head 801 is connected to the water supply port 102b, the connecting head 801 can enter the inner side of the water supply port 102b. After the connecting head 801 enters the inner side of the water supply port 102b, the connecting head 801 is rotated so that the first snapping protrusion 102b-1 engages with the second snapping protrusion 801a.

[0091] When a fire occurs, the fire monitor 401 transmits an electrical signal to the intermediate relay, the intermediate relay establishes a connection between the power supply and the electromagnet 703d, the electromagnet 703d attracts the movable lock column 703b, and an end of the movable lock column 703b is detached from the inner side of the positioning hole 702c. Under the thrust of the first elastic member 601, the inner ring body 602a and the outer ring body 602c move synchronously towards the placing ring body 701a.

When the inner ring body 602a and the outer ring body 602c contact the placing ring body 701la, the placing ring body 701a can stop the inner ring body 602a and the outer ring body 602c, and the inner ring body 602a and the outer ring body 602c cannot mover further. The thrust on the sliding rod 702a can push the sliding rod 702a to continue moving, the sliding rod 702a drives the snap fastener 702b to disengage from the snap tooth set 602e, and the outer ring body 602c is unlocked. The outer ring body 602c rotates in the first direction, so that the swing bar 603a is driven to swing, the load-bearing member 502b-2 is pulled, and the sliding column 502b-1 drives the plug 502b-3 to move away from the water inlet 502a-1.

Therefore, the plug 502b-3 no longer blocks the water inlet 502a-1, so that the water inside the fire pipe body 102a can reach the communicating pipe body 501, and finally reach the protective pipe 102 through the communicating pipe body 501 and spray out, so as to protect the firefighting box.

[0092] Specifically, the synchronization member 702d is provided with a groove M. One end of the groove M is an entry end M1 extending to the side wall of the synchronization member 702d, and the other end is a closed end M2. The pressing column 802 can enter the inner side of the groove M. When the pressing column 802 is rotated in a second direction following the connecting head 801, the pressing column 802 can reach the closed end M2 and push the synchronization member 702d to move in the second direction. When it is required to disconnect the connecting head 801 from the water supply port 102b, it is only required to rotate the connecting head 801 in the first direction, so that the pressing column 802 is detached from the synchronization member 702d from the entry end M1. At this time, the sliding rod 702a can remain locked by the movable lock column 703b.

[0093] Further, the sliding rod 702a is provided with an inclined surface 702a-1. The provision of the inclined surface 702a-1 is to help the movable lock column 703b to re-reach the positioning hole 702c. While the connecting head 801 1s inserted into the water supply port 102b, the pressing column 802 can press the synchronization member 702d to abut the synchronization member 702d against the placing table 703a. At this time, it is only required to rotate the connecting head 801 in the second direction as the connecting head 801 can drive the synchronization member 702d to rotate in the second direction via the pressing column 802, the sliding rod 702a can be driven to rotate in the second direction. When the sliding rod 702a moves in the second direction, the movable lock column 703b first contacts the inclined surface 702a-1, and under the pressure from the inclined surface 702a-1, the movable lock column 703b presses the second elastic member 703c, until the position of the movable lock column 703b corresponds to the position of the positioning hole 702c. The movable lock column 703b can return to the inner side of the positioning hole 702c under the thrust of the second elastic member 703c to lock the position of the sliding rod 702a.

[0094] The power supply duration of the electromagnet 703d can be set by the intermediate relay. In the present embodiment, the single power supply duration of the electromagnet 703d is 10 seconds, so that after the movable lock column 703b is detached from the positioning hole 702c, the attraction of the electromagnet 703d on the movable lock column 703b disappears, facilitating the re-locking of the sliding rod 702a at a later stage.

[0095] Before the operator acts to put out the fire, the fire monitor 401 can be turned off, so as to avoid the problem that the fire monitor 401 reworks and causes the protective pipe 102 to open during the process of firefighting.

[0096] The remaining structures are the same as those in the second embodiment.

[0097] The operation process is as follows. When the operator connects the connecting water pipe 800 to the water supply port 102b, the connecting head 801 enters the inner side of the water supply port 102b. At this time, the pressing column 802 engages with the synchronization member 702d. During the insertion of the connecting head 801 into the water supply port 102b, the pressing column 802 can press the synchronization member 702d, so that the synchronization member 702d pushes the sliding rod 702a, the sliding rod 702a drives the snap fastener 702b to engage with the snap tooth set 602e on the outer ring body 602c, and pushes the outer ring body 602c. Therefore, the outer ring body 602c and the inner ring body 602a move synchronously to press the first elastic member 601.

[0098] At this time, it is only required to rotate the connecting head 801 in the second direction, so that the second snapping protrusion 801a on the connecting head 801 engages with the first snapping protrusion 102b-1 on the water supply port 102b. In this process, the pressing column 802 can drive the synchronization member 702d, and the synchronization member 702d drives the sliding rod 702a to rotate in the second direction along the coaxial groove 701b. At this time, the sliding rod 702a can drive the outer ring body 602c to rotate in the second direction via the snap fastener 702b and the snap tooth set 602e, until the end of the movable lock column 703b enters the inner side of the positioning hole 702c again, that is, the sliding rod 702a is positioned again. In this process, the outer ring body 602c moves in the second direction, and the swing bar 603a drives the load-bearing member 502b-2 via the cross rod 603b and the pull pin 603c to push the sliding column 502b-1, so that the plug 502b-3 closes the water inlet 502a-1, and the protective pipe 102 stops working. The operator can operate by means of the connecting water pipe 800 to put out the fire.

[0099] According to the above technical solution, the operator can complete the closing of the protective pipe 102 and reset the actuating mechanism 600 and the trigger mechanism 700 in the process of connecting the connecting water pipe 800 with the water supply port 102b.
