Example 1
An electric appliance installation cabinet with a protection function, as shown in figures 1-8, comprises a cabinet body 1 and an electric appliance control member group 2; three electric appliance control element groups 2 which are distributed up and down are arranged in the cabinet body 1;
The device also comprises a cylinder 101, an electric roller 102, a dry powder bag 103, an L-shaped round rod 105, a guide rod 106, a supporting frame 107, a connecting seat 108, a connecting plate 109, a first spring 1010, a baffle 1011 and a fusing rope 1012; the top of the cabinet body 1 is connected with a cylinder 101 through bolts, and an outlet 101a is formed in the rear side of the cylinder 101; the center of the cylinder 101 is connected with an electric roller 102 through a bolt; the rotating part of the electric roller 102 is fixedly connected with a dry powder bag 103, fire extinguishing dry powder is filled in the dry powder bag 103, and a sealing part of the discharging end of the dry powder bag 103 is made of a material which is easy to crack; the cylinder 101 is connected with two L-shaped round rods 105 which are symmetrically distributed left and right; three guide rods 106 which are distributed up and down are fixedly connected on each L-shaped round rod 105; three supporting frames 107 which are distributed up and down are fixedly connected to the inner rear side of the cabinet body 1, and each supporting frame 107 is positioned above the corresponding electrical appliance control member group 2; the rear side in the cabinet body 1 is connected with three connecting plates 109 which are distributed up and down, each connecting plate 109 is contacted with a corresponding supporting frame 107, a plurality of round holes 109a are formed in the bottom of each connecting plate 109, and the width of each connecting plate 109 is larger than that of the electrical appliance control unit 2; the bottom of each guide rod 106 is positioned at the front side of the corresponding connecting plate 109; two springs 1010 which are symmetrical left and right are fixedly connected inside each connecting plate 109; all the first springs 1010 on each connecting plate 109 are fixedly connected with a baffle 1011, and each baffle 1011 slides in the corresponding connecting plate 109; each baffle 1011 is fixedly connected with a fusing rope 1012, and the fusing ropes 1012 are wound on the supporting frame 107, and the baffle 1011 is limited by the fusing ropes 1012.
Also included is a connection mount 108; two connecting seats 108 which are distributed symmetrically left and right are arranged above each electric appliance control member group 2, and all the connecting seats 108 are connected with the inner rear side of the cabinet body 1 through bolts; the connecting seats 108 positioned on the same horizontal line are all in rotary connection with the corresponding connecting plates 109.
Also included is a counterweight 104; the discharging end of the dry powder bag 103 is fixedly connected with a balancing weight 104.
The oblique angle 103a is formed in the discharging end of the dry powder bag 103, and the oblique angle 103a is formed in the discharging end of the dry powder bag 103, so that the bottom and the upper part of the discharging end are not in a flush state, and further dry powder rapidly flows out of the discharging end of the dry powder bag 103, and the dry powder is not blocked at the discharging end of the dry powder bag 103 due to the fact that the bottom and the upper part of the discharging end of the dry powder bag 103 are attached together, so that the extinguishing of a fire source is affected.
The fusing rope 1012 is S-shaped and winds on the supporting frame 107, and because the position of the fire source is uncertain, the covering area of the fusing rope 1012 is enlarged by winding the fusing rope 1012 into the S-shaped, so that the fire source can timely fuse the fusing rope 1012, and an alarm is triggered.
The following is the working mode of the above embodiment:
Because the air contains moisture, when the electric cabinet is used for a long time, a circuit is affected with damp, so that a circuit is short-circuited, the circuit is ignited, and the electric cabinet is burnt out, but when the existing electric cabinet is in a fire disaster, dry powder is poured downwards only through a dry powder box arranged in the electric cabinet, a fire source is extinguished, the fire position cannot be accurately extinguished, when the fire position is lower, the dry powder is blocked by an electric control component group 2 above, the dry powder cannot timely extinguish the fire source, the fire is enlarged, and the whole electric cabinet and elements are burnt out;
Therefore, when the middle part in the electrical cabinet fires, the fusing rope 1012 positioned below the middle electrical control part group 2 can be blown by a fire source, but because the position of the fire source is uncertain, the fusing rope 1012 can be baked and fused when the fire source just appears, and therefore, the coverage area is enlarged by winding the fusing rope 1012 into an S shape, so that the fire source can timely fuse the fusing rope 1012;
when the fusing rope 1012 is broken, the baffle 1011 loses the limit of the fusing rope 1012, so that the first spring 1010 is not extruded by the baffle 1011 any more, and the first spring 1010 is ejected from the contracted state, pushing the baffle 1011 to slide forward along the inside of the connecting plate 109, stopping when the baffle 1011 slides to the first spring 1010 to the maximum distance, the round hole 109a is completely leaked, when the baffle 1011 slides forward along the inside of the connecting plate 109, the baffle 1011 moves upwards along the guide rod 106, so that the baffle 1011 is in an inclined state, the inclined plane of the baffle 1011 moves to be aligned to the lower part of the outlet 101a, when the fusing rope 1012 is blown, the fusing rope 1012 triggers the alarm inside the cabinet 1, so that the electric roller 102 is controlled to drive the dry powder bag 103 to rotate anticlockwise when seen from right to left, the discharging end of the dry powder bag 103 moves to the outlet 101a, the discharging end of the dry powder bag 103 drops downwards from the outlet 101a, and the discharging end of the dry powder bag 103 is driven by the balancing weight 104 to drop down quickly, when the balancing weight 104 drives the discharging end of the dry powder bag 103 to drop onto the baffle 1011, the discharging end of the dry powder bag 103 is impacted by more and more dry powder, so that the easily-broken seal inside the discharging end of the dry powder bag 103 is opened, the dry powder flows out from the discharging end of the dry powder bag 103 onto the baffle 1011, the dry powder is guided onto the connecting plate 109 by the baffle 1011 in an inclined state, the dry powder of the connecting plate 109 drops down to a fire source through the round hole 109a to perform accurate extinguishing work on the fire source, and when the dry powder drops from the round hole 109a, because the connecting plate 109 is longer than the electrical control member group 2, when the dry powder drops from the round hole 109a at the connecting plate 109 longer than the electrical control member group 2, the dry powder can float down to the surface of the electrical control member group 2 below to perform pre-protection on the electrical control member group 2 below, the middle electric appliance control component group 2 is prevented from being ignited, so that the temperature of the cabinet body 1 is increased, and the lower electric appliance control component group 2 is prevented from being ignited;
However, because the connection plate 109 is in a flat state, dry powder cannot flow down from the round hole 109a near the rear side of the connection plate 109, so that the fire extinguishing range is limited, and therefore, when the baffle 1011 moves along the guide rod 106, the baffle 1011 drives the connection plate 109 to rotate around the connection seat 108, so that the connection plate 109 also becomes inclined, and dry powder can flow downwards to the round hole 109a near the rear side, so that the fire extinguishing range is enlarged;
When the discharging end of the dry powder bag 103 sags downwards and contacts with the baffle 1011, the bottom and the upper part of the discharging end of the dry powder bag 103 are attached together, so that the dry powder is blocked at the discharging end of the dry powder bag 103 and cannot be discharged normally, and the extinguishing of a fire source is affected.
Example 2
On the basis of the embodiment 1, as shown in fig. 1-3 and 5-9, a cutting assembly is also included; the cutting assembly comprises a pull rope 1013, a second spring 1014, a stop 1015 and a cutter 1016; a plurality of material leakage holes 1011a are formed on the front side of each baffle 1011; a notch 1011b is arranged on the front side of each baffle 1011; the back sides of all the baffles 1011 except the uppermost baffle 1011 are fixedly connected with two stay ropes 1013 which are distributed left and right; all the baffle 1011 front sides except the lowest baffle 1011 are connected with a baffle 1015 in a sliding way, and the baffle 1015 is made of rubber; two springs II 1014 are fixedly connected between each stop 1015 and the inner rear side of the baffle 1011; all baffle 1011 front sides except the lowest baffle 1011 are fixedly connected with a cutter 1016; the pull cord 1013 on the rear side of the lowermost baffle 1011 penetrates the corresponding connection plate 109 and the middle connection plate 109 and is then fixedly connected with the stopper 1015 in the middle baffle 1011, and the pull cord 1013 on the rear side of the middle baffle 1011 penetrates the corresponding connection plate 109 and the upper connection plate 109 and is then fixedly connected with the stopper 1015 in the upper baffle 1011.
The discharge end of the dry powder bag 103 is provided with a plurality of weak layers 103b, when the first spring 1010 drives the cutter 1016 to pop up through the baffle 1011, the cutter 1016 moves obliquely upwards along the guide rod 106, so that the end part of the cutter 1016 is attached to the surface of the suspended dry powder bag 103 to move upwards, and when the cutter 1016 enters the weak layers 103b, the cutter 1016 can scratch the weak layers 103b and enter the dry powder bag 103, and dry powder is guided from the cutter 1016 to a fire source.
The following is the working mode of the above embodiment:
Because the temperature is higher when the line fires and the fire is upward, the upper line can cause the fire due to the high temperature and the fire, at the moment, because the dry powder bag 103 is hung down, after the upper fusing rope 1012 is fused, the upper baffle 1011 is ejected by the first spring 1010, the baffle 1011 can only contact with the surface of the dry powder bag 103, and can not guide the dry powder to flow to the middle connecting plate 109, so that the fire in the middle can not be extinguished, therefore, when the upper baffle 1011 is ejected by the first spring 1010, the cutter 1016 can be driven to eject simultaneously, the cutter 1016 moves along the guide rod 106 along the baffle 1011, so that the end of the cutter is attached to the surface of the dry powder bag 103 which is hung down, and moves obliquely upwards along the surface of the dry powder bag 103, when the cutter 1016 enters the weak layer 103b, the cutter can scratch the weak layer 103b into the dry powder bag 103, the falling dry powder is blocked by the cutter 1016, the upper baffle 1011 is guided to the upper baffle 1011, the dry powder flows to the upper baffle 1011, and falls to the upper connecting plate 109 from the upper side, and the fire source is extinguished by the baffle 1016, and the upper connecting plate 109 is dropped to the fire source;
It should be noted that: when the electrical control unit 2 fires and the fusing rope 1012 blows to enable the baffle 1011 to pop up, the cutter 1016 can pop up along with the baffle 1011, and the cutter 1016 cannot contact the dry powder bag 103, so that the dry powder bag 103 is prevented from being cut;
However, because the upper cutter 1016 blocks the falling dry powder, if the middle fire source is not completely extinguished, the middle fire source is re-ignited because no subsequent dry powder is supplied, so that larger fire is caused, therefore, when the middle baffle 1011 pops up, the pull rope 1013 pulls the block 1015 in the upper baffle 1011, so that the corresponding spring two 1014 is compressed by the upper block 1015 to enable the block 1015 to enter the baffle 1011, when the block 1015 enters the baffle 1011, the leakage hole 1011a at the upper notch 1011b leaks out, when the upper cutter 1016 is inserted into the dry powder bag 103, part of dry powder falls down to the middle baffle 1011 through the leakage hole 1011a, and then falls down to the fire source which is not extinguished yet from the middle round hole 109a, so that the problem that the larger fire is caused because the middle dry powder is not fully extinguished if the middle fire source is not completely extinguished, because the upper cutter 1016 blocks the falling dry powder is not supplied yet, is avoided.
Example 3
On the basis of the embodiment 2, as shown in fig. 1-4, a dithering component is further included; the shaking component comprises a spring III 201, a top block 202, a deflector rod 203 and a shaking unit; a spring III 201 is fixedly connected to the left side and the right side in the cylinder 101; the other end of each spring III 201 is fixedly connected with the corresponding L-shaped round rod 105; three annular equally distributed top blocks 202 are fixedly connected to the left side and the right side of the rotating part of the electric roller 102; the dry powder bag 103 is wound to form a spiral curl shape, the initial state of the dry powder bag 103 is set to be the spiral curl shape, the speed of agglomeration of the dry powder in the inner layer dry powder bag 103 under the influence of moist air is slowed down, and a gap 103c is formed after the dry powder bag 103 is wound; all L-shaped round bars 105 are fixedly connected with a deflector rod 203 together, and the deflector rod 203 is positioned in the gap 103c; the guide bar 106 and the shutter 1011 are commonly connected to a shaking unit.
The dithering unit comprises a convex ball 204 and a convex strip 205; a plurality of convex balls 204 are fixedly connected on each guide rod 106; seven raised strips 205 which are distributed up and down are fixedly connected to the left side and the right side of the front part of each baffle 1011.
The following is the working mode of the above embodiment:
When the dry powder in the dry powder bag 103 is placed for a long time and absorbs moisture in the air, so that all the dry powder in the dry powder bag 103 is agglomerated, and when a fire disaster occurs, the agglomerated dry powder in the dry powder bag 103 cannot extinguish the fire disaster, so that the initial state of the dry powder bag 103 is set to be a spiral curl shape, the agglomeration speed of the dry powder in the inner dry powder bag 103 under the influence of moist air is slowed down, the problem that the dry powder in the dry powder bag 103 is placed for a long time and absorbs moisture in the air, so that all the dry powder in the dry powder bag 103 is agglomerated, and the agglomerated dry powder in the dry powder bag 103 cannot effectively extinguish the fire disaster when the fire disaster occurs is avoided;
it should be noted that, when the cabinet 1 is used for a certain period of time, the dry powder bags 103 are maintained periodically by manpower, so that the dry powder in the dry powder bags 103 is prevented from being completely agglomerated due to the influence of moist air, the subsequent fire suppression is affected, and the dry powder in the inner layer after the dry powder bags 103 are curled is set to be spirally curled;
Although the problem that the dry powder in the dry powder bag 103 is agglomerated due to the influence of moist air is relieved by setting the initial state of the dry powder bag 103 into a spiral curl shape, the dry powder in the dry powder bag 103 keeps curl shape for a long time, the dry powder in the dry powder bag 103 is agglomerated due to the curling force, therefore, when the electric roller 102 drives the dry powder bag 103 to rotate and descend, the electric roller 102 drives the top block 202 to synchronously rotate, so that the top block 202 can press the L-shaped round rod 105, the L-shaped round rod 105 downwards presses the spring three 201 to shrink, the L-shaped round rod 105 drives the deflector rod 203 to downwards stir and press the spiral curl-shaped dry powder bag 103, so that the agglomerated dry powder in the dry powder bag 103 is extruded loosely, when the top block 202 rotates to leave the L-shaped round rod 105, the spring three 201 pushes the L-shaped round rod 105 to upwards move and reset, so that the L-shaped round rod 105 drives the deflector rod 203 to upwards stir and press the spiral curl-shaped dry powder bag 103, and the agglomerated dry powder in the dry powder bag 103 is extruded loosely, and the problem that the agglomerated dry powder 103 is still the dry powder in the curl shape is kept for a long time because of the curling force is avoided;
It should be noted that, by setting the initial state of the dry powder bag 103 to be a spiral curl shape, although the dry powder in the dry powder bag 103 is agglomerated, unlike the dry powder which is agglomerated due to the influence of humid air, the dry powder which is agglomerated due to the influence of humid air has a small amount of moisture and is not easy to be extruded and loosened by the deflector rod 203, therefore, by setting the initial state of the dry powder bag 103 to be a spiral curl shape, the service life of the dry powder bag 103 can be ensured to a certain extent, and the dry powder bag 103 is set to be a spiral curl shape, when a fire is extinguished, the dry powder in the inner layer dry powder bag 103 is extruded and loosened by slowing down the agglomeration speed of the dry powder due to the influence of humid air and then being extruded and loosened by the deflector rod 203, so that the dry powder which is agglomerated due to the influence of the upper part and the middle part of the dry powder bag 103 is hard to be extruded and loose and the dry powder is not easy to be extruded and loose and the dry powder which is agglomerated by the lower part of the dry powder bag 103 is prevented from influencing the normal discharge of the subsequent dry powder, so as to ensure that the fire is extinguished effectively extinguished;
meanwhile, when the electric roller 102 rotates, after the discharging end of the dry powder bag 103 contacts with the baffle 1011 and releases dry powder, the electric roller 102 continues to rotate, so that when the L-shaped round rod 105 is driven to reciprocate up and down by the cooperation of the top block 202 and the spring III 201, the L-shaped round rod 105 drives the guide rod 106 to reciprocate up and down, so that the guide rod 106 drives the connecting plate 109 and the baffle 1011 to reciprocate up and down around the connecting seat 108, the dry powder remained on the surfaces of the connecting plate 109 and the baffle 1011 falls to a fire source from the round hole 109a and the leakage hole 1011a, the waste of the dry powder is avoided, the extinguishing rate of the fire source is accelerated, and the length of the dry powder bag 103 is longer than that of the baffle 1011 at the lowest part, after the electric roller 102 continues to release the dry powder bag 103, the discharging end of the dry powder bag 103 is closer to the round hole 109a on the connecting plate 109, the dry powder flows into the round hole 109a directly after flowing out from the discharging end of the dry powder bag 103, and drops down, and the extinguishing rate of the fire source is further accelerated;
Meanwhile, in the process that the L-shaped round rod 105 drives the guide rod 106 to reciprocate up and down, the convex ball 204 is driven to synchronously move, when the guide rod 106 drives the convex ball 204 to slide on the front side of the baffle 1011, the convex ball 204 contacts with the convex strips 205 to generate vibration, so that the connecting plate 109 and the baffle 1011 are also affected by the vibration, the dry powder remained on the surfaces of the connecting plate 109 and the baffle 1011 falls more rapidly when being vibrated, and the extinguishing degree of the dry powder on fire is maximized;
Meanwhile, the connecting plate 109 and the baffle 1011 are made to reciprocate up and down around the connecting seat 108, and then the connecting plate 109 and the baffle 1011 are vibrated by matching the convex balls 204 and the convex strips 205, so that the dry powder which falls on the connecting plate 109 and is agglomerated can fall out of the round hole 109a, and the round hole 109a is prevented from being blocked.
While the invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. The scope of the following claims is to be accorded the broadest interpretation so as to encompass all such modifications and equivalent structures and functions.
