Preferably, an arc-shaped flange 3 is arranged at the free end of the movable plate, so that the movable plate can be conveniently re-opened after the open fire is extinguished.
Preferably, the fuse 7 is fixed at the bottom of the fixed plate through the bottom plate 6, and the position of the fuse 7 is arranged at the middle of the open end of the cover 1, so as to ensure that the fuse 7 can be heated quickly after a fire to perform corresponding actions.
Example 2
As shown in fig. 1 to 7, the present embodiment is based on embodiment 1, in which the arrangement mode of the fuse 7 is divided according to the leakage amount of the flammable liquid storage tank in actual use, and includes two modes, one of which is: the fuse 7 comprises a shell 71 with an open bottom, a secondary fusing post 76 and a connecting rod 79 which are parallel to each other, wherein the shell 71 is fixed above the inside of the cover 1, the open end of the shell is opposite to a combustible liquid storage tank in the inside of the cover 1, one end of the connecting rod 79 is provided with a linkage plate 77, the linkage plate 77 is arranged in the shell 71, and the other end of the connecting rod 79 movably penetrates through the side wall of the shell 71 and then outwards extends to be connected with a top plate 78;
one end of the secondary fusing post 76 contacts with the side wall of the linkage plate 77, the other end of the secondary fusing post 76 is connected with the side wall of the shell 71, the secondary spring 75 in a compressed state is sleeved on the outer wall of the secondary fusing post 76, and two ends of the secondary spring 75 are respectively connected with the side wall of the shell 71 and the outer wall of the secondary fusing post 76.
The fuse 7 is used as a key component for extinguishing open fire generated by leakage of the flammable liquid storage tank, and comprises a rectangular shell 71 with an open bottom and right opposite to the flammable liquid storage tank, a secondary fusing post 76 is horizontally arranged in the shell 71, a secondary spring 75 is sleeved on the outer circumferential wall of the secondary fusing post 76, as two ends of the secondary spring 75 are respectively connected with the inner side wall of the shell 71 and the outer wall of the secondary fusing post 76, the secondary spring 75 is always in a compressed state, the secondary fusing post 76 is heated to break after the open fire is generated, then the limit on the secondary spring 75 is released, the secondary spring 75 can generate a thrust on the linkage plate 77 after being deformed in a restoring manner, so that the connecting rod 79, the top plate 78 and the pushing plate 8 form impact on the supporting plate 4, and the supporting plate 4 can be ensured to be converted from an inclined state to a horizontal state in a short time.
The second step is: a primary fusing post 711 is further arranged between the side wall of the shell 71 and the side wall of the linkage plate 77, the end part of the primary fusing post 711 contacts with the side wall of the linkage plate 77, an arc-shaped clamping groove 74 is formed in the outer wall of the primary fusing post 711 along the axial direction of the primary fusing post 711, and the clamping groove 74 partially wraps the outer circumferential wall of the secondary fusing post 76; and a primary spring 710 in a compressed state is arranged between the side wall of the shell 71 and the side wall of the linkage plate 77, two ends of the secondary spring 75 are respectively connected with the side wall of the shell 71 and the outer wall of the primary fusing post 711, and the secondary fusing post 76 is opposite to the bottom of the cover body 1.
As an optimization scheme of the first mode, the primary fusing post 711 and the secondary fusing post 76 are combined, so that the state conversion of the cover plate 2 is more flexible, and the following specific operation is performed: the secondary fusing post 76 is heated firstly by the open fire generated by the leakage of the combustible liquid storage tank, namely the secondary fusing post 76 is broken firstly due to the heating, and the secondary spring 75 generates first impact on the linkage plate 77 after being released, namely the pushing plate 8 acts on the supporting plate 4 for the first time, so that the lock pin 5 can be smoothly removed from the locking hole; after the secondary fusing post 76 is heated and broken, the primary fusing post 711 is heated by open fire, and because the diameter of the primary fusing post 711 is larger than that of the secondary fusing post 76, the time from heating to breaking of the primary fusing post 711 is longer than that of the secondary breaking body, and similarly, the broken primary fusing post 711 releases the primary spring 710, and the elastic force generated by the recovery deformation of the primary spring 710 can perform secondary impact on the side wall of the driving linkage plate 77, the top plate 78 and the pushing plate 8 to accelerate the overturning speed of the supporting plate 4 around the locking pin 5, so as to improve the moving speed of the cover plate 2 towards the open end of the cover body 1.
It should be noted that, the diameter of the primary fusing post 711 is larger than the diameter of the secondary fusing post 76, and the outer diameter of the primary spring 710 is larger than the outer diameter of the secondary spring 75, that is, the elastic force released by the primary spring 710 when the primary fusing post 711 breaks is larger than the elastic force released by the secondary spring 75, so as to realize the adjustment of the downward movement speed of the free end of the cover plate 2.
Preferably, the number of the clamping grooves 74 is set to be a plurality of the clamping grooves which are uniformly distributed on the outer circumferential wall of the primary fusing post 711, and the secondary fusing posts 76 are correspondingly arranged in the clamping grooves 74, so that thrust forces can be generated in different directions when the fuse 7 is heated unevenly, and the locking pin 5 can be ensured to move out of the locking hole.
Example 3
As shown in fig. 1 to 7, in this embodiment, on the basis of embodiment 2, after the fuse 7 is optimized, that is, on the premise of adopting a composite fusing post, the chute is correspondingly adjusted, and the conventional rectangular linear slot or the rounded linear slot is not adopted, which is specifically as follows: the sliding groove comprises a primary sliding groove 9, a locking sliding groove 10 and a secondary sliding groove 11, wherein the primary sliding groove 9 is communicated with the secondary sliding groove 11, the locking sliding groove 10 is in the shape of an arc and is positioned at the joint of the primary sliding groove 9 and the secondary sliding groove 11, the secondary sliding groove 11 is communicated with the locking hole, and the locking sliding groove 10 and the locking hole are respectively positioned on the same side of the secondary sliding groove 11.
In actual operation, the lock pin 5 moves along the chute, and the most ideal moving mode between the lock pin 5 and the chute is as follows: after the lock pin 5 is moved out of the locking hole, the lock pin is not contacted with the inner side wall of the chute, namely, sliding friction is not generated, and the cover plate 2 and the support plate 4 start to move downwards while inclining under the action of the gravity of the lock pin; in this technical solution, when the secondary fusing post 76 and the primary fusing post 711 release the secondary spring 75 and the primary spring 710 on the respective outer circumferential walls step by step, when the restoring force generated by the secondary spring 75 is transmitted to the support plate 4, that is, the overturning action of the cover plate 2 is started, and when the restoring force generated by the primary spring 710 is transmitted to the support plate 4, the overturning speed of the cover plate 2 is accelerated, because the support plate 4 moves down synchronously while the support plate 4 performs secondary impact, the most ideal moving mode between the lock pin 5 and the chute is realized, that is, in a certain distance, no sliding friction is generated between the lock pin 5 and the chute, that is, the resistance applied when the support plate 4 moves down in the area is minimum, and the moving speed is fastest.
Furthermore, the leakage amount generated when the flammable liquid storage tank is used is variable, and when the leakage amount is small, the open flame generated in the cover body 1 is small in scale, the oxygen content of the air in the cover body 1 is reduced to 16% piece by piece after the combustion of the flammable liquid is met, the continuous combustion of the flammable liquid is insufficient, at the moment, the generated heat in the combustion process of the flammable liquid can meet the requirement of breaking the secondary fusing post 76, namely, the pushing plate 8 is driven by the secondary spring 75 with small restoring force to form impact on the supporting plate 4, and the free end of the cover plate 2 is driven to approach the open end of the cover body 1, wherein the sliding groove comprises three parts, namely a primary sliding way 9, a locking sliding way 10 and a secondary sliding groove, the state is kept after the lock pin 5 moves along the primary sliding way 9 to the locking sliding way 10, for the flammable liquid storage tank with small leakage amount, the oxygen consumption in the cover body 1 is reduced again, namely, the generated open flame can be extinguished in a short time, and even if no operator finds that the cover plate 2 is reset in a time period, the normal operation of the flammable liquid can be guaranteed; when the leakage amount is large, the fire situation occurring in the cover body 1 is large, meanwhile, the temperature fluctuation in the fuse 7 is large, the secondary fusing post 76 and the primary fusing post 711 sequentially realize fracture, namely the secondary spring 75 and the primary spring 710 impact the supporting plate 4 in sequence, wherein the lock slide way 10 has the same effect as the locking hole, and the lock pin 5 can be limited, the difference is that the lock pin 5 is limited at different points in the chute, the elastic force generated by the recovery of the primary spring 710 after the primary fusing post 711 breaks can enable the lock pin 5 to move out of the locking slide way 10 and move continuously along the secondary chute again until reaching the limit position, at the moment, the free end of the cover plate 2 is completely attached to the end face of the open end of the cover body 1, the complete isolation of the inside and the outside of the cover body 1 is realized, and when the oxygen content in the cover body 1 is consumed until the condition of continuous combustion cannot be met, the open fire is extinguished.
The support plate 4 is provided with a transition slide way 14 parallel to the primary slide way 9 and the secondary slide way 11, one end of the transition slide way 14 is communicated with the primary slide way 9 through a locking slide way 10, the other end of the transition slide way 14 is communicated with the secondary slide through a guiding slide way 15, the guiding slide way 15 is arc-shaped and is used for guiding the lock pin 5 to smoothly enter the transition slide way 14 from the secondary slide way 11, and when the corresponding execution action is started after the fuse 7 is combined with heat generated by burning the combustible liquid with small leakage amount, the specific working principle of the slide way application is as follows: the lock pin 5 is firstly moved out of the locking hole, the supporting plate 4 is unlocked, the gravity of the cover plate 2 and the supporting plate 4 starts to move downwards, and the lock pin 5 enters into the transition slide way 14 by being guided by the arc-shaped guiding slide way 15 in the process of tilting and moving downwards of the supporting plate 4 until the lock pin 5 is unlocked from the locking slide way 10, and the transition slide way 14 is parallel to the primary slide way 9, the linear distance between the transition slide way 14 and the fuse 7 is larger than that between the transition slide way 14 and the secondary slide way 11, the locking slide way locks the supporting plate 4 for the second time in the tilting process of the supporting plate 4, so that the overturning action of the cover plate 2 is stopped, and a small amount of leaked combustible liquid is correspondingly processed, namely, the air inlet space above the cover body 1 is reduced, and the oxygen content inside the cover body 1 is reduced below the combustion critical point; when the leakage amount of the combustible liquid in the cover body 1 is large, the primary fusing post 711 and the secondary fusing post 76 are heated and broken, and can generate two impacts on the supporting plate 4, so that the supporting plate 4 can be continuously turned over, namely, the lock pin 5 can rapidly move from the locking slide way 10 to the primary slide way 9 so as to start to continuously move the lock pin 5 and the supporting plate 4 until the cover plate 2 completely closes the open end of the cover body 1, and new air sources are prevented from entering. It should be noted that, the locking slide way 10 communicated with the transition slide way 14 is also in a circular arc shape, and the direction of the opening of the central angle of the circle corresponding to the transition slide way 14 is different from the direction of the opening of the central angle of the circle corresponding to the locking hole, so that the locking pin 5 can be ensured to be smoothly moved out of the locking hole in the primary locking state, and the locking pin 5 can be secondarily locked in the locking slide way 10 when the cover plate 2 needs to be kept in the state after being overturned by a certain extent.
While it is preferable to provide a heat conductive plate 712 at the open end of the bottom of the housing 71, which can rapidly transfer heat to the secondary fuse post 76 and the primary fuse post 711, and at the same time can concentrate broken fragments of the secondary fuse post 76 and the primary fuse post 711 in the housing 71.
In this embodiment, the axial length of the primary fusing post 711 and the secondary fusing post 76 can be adjusted inside the housing 71 according to the specific model of the cover 1, for example, a thrust post coaxial with the connecting rod 79 is provided on the side wall of the housing 71, and a disc 73 is provided on the end of the thrust post opposite to the connecting rod 79, wherein the diameter of the disc 73 is larger than that of the thrust post, and then the ends of the primary fusing post 711, the secondary fusing post 76, the primary spring 710 and the secondary spring 75 are fixed on the disc 73, and the thrust post is in threaded connection with the housing 71, so that the replacement can be performed at any time.

It should be noted that the best connection between the support end and the end of the fixing plate 701 is a vertical connection, so as to ensure that the elastic force generated by the compression spring 706 during the return deformation can fully act on the inner case 704.
