Description

Technical Field

[0001] The invention relates to the technical field of safe doors, in particular to a safe door which can be applied to flood disasters. Background Art

[0002] During the use of vault doors, it was found that vault doors usually only consider the prevention of abnormal opening, ignoring the protection against natural disasters. In the event of a flood, water will seep into the vault door. As an important facility for protecting valuables, the waterproof performance of the vault door is directly related to the safety of the property in the vault. Once the vault door leaks, it may cause the property in the vault to become damp, moldy or even damaged, causing huge economic losses to the relevant units or individuals.

[0003] The existing safe door still has the following defects when in use:

[0004] 1. During the long-term use of the existing safe door, natural disasters such as earthquakes and storms may directly cause impact or collision to the safe door, causing deformation, cracks and other damage to the door body or door frame. These damages will not only affect the overall structural strength of the safe door, but also may destroy its waterproof sealing performance, further damage these seals, causing the seals to be damaged and lose the sealing effect, causing water leakage, causing the property in the safe to become damp, moldy or even damaged, causing huge economic losses to the relevant units or individuals.

[0005] 2. Existing safe doors can usually only be manually operated and controlled during use so that the safe doors can be sealed when responding to flood impacts. However, due to flood disasters, it may be impossible to manually operate the safe doors, so that the safe doors cannot adaptively strengthen the waterproof seal of the safe doors due to flood impacts, causing erosion and damage to the inside of the safe doors due to water leakage, thereby reducing the overall protective effect of the safe doors and affecting their use.

[0006] Therefore, a safe door that can be applied to flood disasters is proposed to solve the above problems. Summary of the invention

[0007] In view of this, the technical problem to be solved by the present invention is to propose a safe door that can be used for flood disasters, so as to solve the problems of safe door leakage and difficulty in automatic protection in the prior art.

[0008] To achieve the above object, the present invention provides the following technical solution: a safe door applicable to flood disasters, comprising a wall, a curved hammer door rotatably connected to the wall, a push plate slidably connected to the middle of the curved hammer door, a water leakage detection mechanism and an automatic sealing and waterproof mechanism, the water leakage detection mechanism is arranged in the wall, and the automatic sealing and waterproof mechanism is arranged on the push plate;

[0009] The water leakage detection mechanism is used for water leakage detection of curved hammer doors;

[0010] The automatic sealing waterproof mechanism is used for automatic protection after the arc hammer door leaks.

[0011] Preferably, the preliminary extrusion waterproof mechanism is arranged in the curved hammer door, and the preliminary extrusion waterproof mechanism is used for sealing the curved hammer door. The preliminary extrusion waterproof mechanism includes a threaded turntable, and the threaded turntable is threadedly connected with a threaded barrel, and the outer surface of the threaded barrel is slidably connected to the middle part of the curved hammer door.

[0012] Preferably, the end of the threaded barrel away from the threaded turntable is fixedly connected to the push plate, the arc hammer door is fixedly connected to a sealing ring on the side close to the push plate, a rubber pad is provided on the side of the push plate close to the arc hammer door, and a triangular extrusion plate is provided in the multifunctional groove.

[0013] Preferably, one end of the triangular extrusion plate is fixedly connected to the arc-surface hammer door, and the other end of the triangular extrusion plate is fixedly connected to the push plate. A rubber pad is provided on the multifunctional groove, and one end of the rubber pad is fixedly connected to the arc-surface hammer door, and the other end of the rubber pad is fixedly connected to the push plate.

[0014] Preferably, the water leakage detection mechanism comprises a water collecting detection groove, which is arranged in the middle of the push plate, and L-shaped liquid passing plates are fixedly connected to both sides of the water collecting detection groove, and water passing holes are arranged in the L-shaped liquid passing plates.

[0015] Preferably, an L-shaped closing plate is provided above the L-shaped liquid-passing plate, the L-shaped closing plate is rotatably connected to the inner wall of the water collection detection tank, and a floating ball is provided in the middle of the water collection detection tank.

[0016] Preferably, the automatic sealing and waterproof mechanism comprises a driving disk, a middle portion of the driving disk is rotatably connected to a middle portion of the push disk, and an arc-shaped extrusion groove is provided on the circumference of the driving disk.

[0017] Preferably, an extrusion column is slidably connected in the arc-shaped extrusion groove, an angled extrusion plate is fixedly connected to the bottom of the extrusion column, the angled extrusion plate is slidably connected to the push plate, and an extrusion groove is provided at one end of the wall close to the angled extrusion plate and away from the extrusion column.

[0018] Compared with the prior art, the safe door provided by the present invention can be applied to flood disasters and has the following beneficial effects:

[0019] 1. Through the design of triangular extrusion plate and rubber pad, when the operator manually operates the threaded turntable, it can not only lock the vault door, but also activate the sealing mechanism at the same time, which can effectively prevent water leakage. At the same time, the arc-shaped hammer door components adopt a unique arc and cone design. When the flood and the stones and other debris it carries are flushed, they will naturally push the arc-shaped hammer door. Through the mutual extrusion between the arc surface of the arc-shaped hammer door and the arc surface of the push plate, this extrusion will not only not cause serious damage to itself, but can effectively reduce the impact and damage to the wall components through the setting of the sealing pad configured on the outer surface of the arc-shaped hammer door. In addition, this extrusion effect actually strengthens the sealing effect between the arc-shaped hammer door components and the wall components. In the extreme environment of continuous flood impact, this dynamic sealing enhancement mechanism can significantly reduce the occurrence of water leakage, thereby ensuring the safety and dryness inside the vault.

[0020] 2. Through the setting of the L-shaped closing plate in the water leakage detection mechanism, when the sealing gasket in the water collection detection tank may be damaged due to long-term use and aging, causing leakage, the infiltrated water will gradually flow into the water collection detection tank under the action of gravity, and the buoyancy of the water will gradually push the floating ball to push the L-shaped closing plate above, so that the upper L-shaped closing plate begins to contact to form a loop, and start the automatic sealing and waterproofing mechanism. The automatic detection and control of the water leakage detection mechanism can protect the vault door from leakage in real time, and the automatic sealing and waterproofing mechanism can timely fix the push plate protection. The automatic sealing and waterproofing mechanism can not only stabilize the vault door, but also generate a certain amount of extrusion between the push plate and the arc hammer door through the rotation of the driving plate. Therefore, the triangular extrusion plate can be squeezed again through extrusion, so that the rubber pad is driven to fit the wall through the extrusion of the triangular extrusion plate, thereby preventing the leakage from occurring again.

[0045] Compared with the prior art, the implementation of this embodiment can effectively reduce the impact and damage to the wall 1 component, and the squeezing effect actually strengthens the sealing effect between the arc hammer door 11 component and the wall 1 component. In the extreme environment of continuous flood impact, this dynamic sealing enhancement mechanism can significantly reduce the occurrence of water leakage, thereby ensuring the safety and dryness inside the vault.

[0046] For further examples, please refer to Figures 1 to 8 As shown:

[0047] The water leakage detection mechanism 3 includes a water collection detection groove 31, which is arranged in the middle of the push plate 12, and L-shaped liquid-passing plates 32 are fixedly connected to both sides of the water collection detection groove 31, and water holes are arranged in the L-shaped liquid-passing plates 32;

[0048] An L-shaped closing plate 33 is provided above the L-shaped liquid-passing plate 32. The L-shaped closing plate 33 is rotatably connected to the inner wall of the water collecting detection tank 31. A floating ball 34 is provided in the middle of the water collecting detection tank 31.

[0049] The automatic sealing and waterproof mechanism 4 includes a driving disk 41, the middle portion of which is rotatably connected to the middle portion of the push disk 12, and an arc-shaped extrusion groove 42 is provided on the circumference of the driving disk 41;

[0050] An extrusion column 43 is slidably connected in the arc-shaped extrusion groove 42, an oblique extrusion plate 44 is fixedly connected to the bottom of the extrusion column 43, and the oblique extrusion plate 44 is slidably connected to the push plate 12. An extrusion groove 45 is formed at one end of the wall 1 close to the oblique extrusion plate 44 and away from the extrusion column 43;

[0051] Wherein: a micro motor is installed in the middle of the push plate 12, wherein the driving shaft of the micro motor is fixedly connected to the middle of the driving plate 41.

[0052] Compared with the prior art, through the implementation of this embodiment, the automatic sealing and waterproof mechanism 4 can not only stabilize the safe door, but also, through the rotation of the driving plate 41, a certain extrusion can be generated between the push plate 12 and the curved hammer door 11, so that the triangular extrusion plate 24 can be squeezed again by extrusion, thereby driving the rubber pad 25 to fit with the wall 1 through the extrusion of the triangular extrusion plate 24, thereby preventing water leakage from occurring again.

[0053] Everything in the above example works like this:

[0054] In the initial state: the micro motor is not started and the triangular extrusion plate 24 is not extruded.

[0055] The following is the working process of the preliminary squeezing waterproof mechanism 2 for preliminary protection against water leakage:

[0056] When in use, the operator first closes the arc-surface hammer door 11 on the wall 1, and then the operator rotates the threaded cylinder 22 threadedly connected to the threaded turntable 21 clockwise to start sliding along the arc-surface hammer door 11 to the left. Figure 4 As shown, because the end of the threaded barrel 22 away from the threaded rotary disk 21 is fixedly connected to the middle of the threaded rotary disk 21, and the push plate 12 is slidably connected to the middle of the arc hammer door 11, as shown in FIG. Figure 4 As shown, at this time, the operator rotates the threaded turntable 2 clockwise to drive the push plate 12 to start sliding to the left in the arc-surface hammer door 11 synchronously. At this time, the arc-surface hammer door 11 is provided with a sealing ring fixed on one side of the push plate 12, and a certain buffering and shock-proof effect can be generated when the push plate 12 slides in the arc-surface hammer door 11, thereby reducing the damage to the vault door during rotation.

[0057] like Figure 5As shown, since the push plate 12 slides to the left in the arc-surface hammer-shaped door 11, at this time, because one end of the triangular extrusion plate 24 is fixedly connected to the arc-surface hammer-shaped door 11, and the other end of the triangular extrusion plate 24 is fixedly connected to the push plate 12, a rubber pad 25 is provided on the multifunctional groove 26, one end of the rubber pad 25 is fixedly connected to the arc-surface hammer-shaped door 11, and the other end of the rubber pad 25 is fixedly connected to the push plate 12, and the middle part of the triangular extrusion plate 24 adopts a semi-arc surface setting. Because the triangular extrusion plate 24 is made of high-toughness metal, when the triangular extrusion plate 24 is squeezed to the left by the push plate 12, the triangular extrusion plate 24 will The plate 24 begins to deform. Since the middle part of the triangular extrusion plate 24 is set with a hollow semi-arc surface, the triangular extrusion plate 24 is squeezed to the left side, thereby causing the triangular extrusion plate 24 to deform toward the side close to the wall 1. At this time, the deformation of the triangular extrusion plate 24 drives the rubber pad 25 to begin to squeeze toward the side close to the wall 1. Since one end of the rubber pad 25 is fixedly connected to the arc hammer door 11, and the other end of the rubber pad 25 is fixedly connected to the push plate 12, the extrusion and fit between the rubber pad 25 and the wall 1 will produce a sealing effect for the vault door. Compared with the traditional sealing pad, which only It can achieve a certain sealing effect, and through the arrangement of the present invention, it can not only provide an additional protective layer on the basis of the initial sealing, but also effectively prevent the penetration of liquid, gas or dust, thereby significantly improving the sealing effect. Through the design of the triangular extrusion plate 24 and the rubber pad 25, when the operator manually operates the threaded turntable 21, it can not only lock the vault door, but also activate the sealing mechanism at the same time, which can effectively prevent the occurrence of water leakage. At the same time, the components of the arc hammer door 11 adopt a unique arc and cone design. When the flood and the stones and other debris it carries are washed away during the flushing process, , it will naturally push the curved hammer door 11, through the mutual compression between the curved surface of the curved hammer door 11 and the curved surface of the push plate 12, and this compression will not only not cause serious damage to itself, but can also be configured on the outer surface of the curved hammer door 11 The sealing gasket can effectively reduce the impact and damage to the wall 1 component, and this squeezing effect actually strengthens the sealing effect between the curved hammer door 11 component and the wall 1 component. In the extreme environment of continuous flood impact, this dynamic sealing enhancement mechanism can significantly reduce the occurrence of water leakage, thereby ensuring the safety and dryness inside the vault.

[0058] Please refer to the above working process Figures 1 to 8 .

[0059] The following is the working process of gasket aging detection and automatic water-proof sealing:

[0060] During use, in order to prevent the sealing gasket on the arc hammer door 11 in the safe door from being damaged due to corrosion caused by long-term use, the safe door will leak. At this time, the water collection detection groove 31 in the present invention is set. When the sealing gasket in the water collection detection groove 31 is damaged due to aging, causing water leakage, the infiltrated water will gradually flow into the water collection detection groove 31 under the action of gravity, and the buoyancy of the water will gradually push the floating ball 34 to push the upper L-shaped closing plate 33, so that the symmetrically arranged L-shaped closing plates 33 above begin to contact each other. When the L-shaped closing plates 33 are in contact, a loop is formed, and the automatic sealing and waterproofing mechanism 4 is started. At this time, because a micro motor is installed in the middle of the push plate 12, the micro motor drives The shaft is fixedly connected to the middle of the driving disk 41, and when the L-shaped closing plates 33 are closed to each other, the micro motor starts to rotate counterclockwise through the control of the controller. At this time, the driving disk 41 starts to rotate counterclockwise synchronously under the drive of the motor driving shaft. Because the driving disk 41 is provided with an arc-shaped extrusion groove 42 on the circumference, and an extrusion column 43 is slidably connected in the arc-shaped extrusion groove 42, and an angled extrusion plate 44 is fixedly connected to the bottom of the extrusion column 43, and the angled extrusion plate 44 is slidably connected to the push plate 12, when the driving disk 41 rotates in the clockwise direction, the arc-shaped extrusion groove 42 and the extrusion column 43 are pressed against each other, which drives the angled extrusion plate 44 to slide toward the side of the wall 1. At this time, because the angled extrusion plate 44 is provided with an inclined surface at one end away from the extrusion column 43, as shown in FIG. Figure 8 As shown, an extrusion groove 45 is provided at one end of the wall 1 close to the angled extrusion plate 44 and away from the extrusion column 43. When the inclined surface of the angled extrusion plate 44 begins to be extruded to the inclined surface of the extrusion groove 45, the mutual extrusion of the inclined surfaces will drive the push plate 12 to start sliding toward the arc-surface hammer-shaped door 11. Because the arc-surface hammer-shaped door 11 is closed in the wall 1 by the existing locking, when the push plate 12 slides toward the side of the arc-surface hammer-shaped door 11, it will drive the push plate 12 to be extruded again. Figure 5The triangular extrusion plate 24 shown in the figure is deformed, so that the triangular extrusion plate 24 can squeeze the rubber pad 25 again, so that the rubber pad 25 is sealed with the wall 1 again. Compared with the traditional sealing pad which only has a single anti-leakage function, the arrangement of the present invention can provide a sealing effect even if the vault door may be directly impacted or collided due to natural disasters such as earthquakes and storms. In addition, the triangular extrusion plate 24 of the present invention can work together with the rubber pad 25 to make the arc-surface hammer door 11 more stable when subjected to external impact, thereby reducing the arc-surface hammer door 11. If the sealing gasket is damaged and causes water leakage to occur again, the automatic detection and control of the water leakage detection mechanism 3 can protect the safe door from water leakage in real time, and the push plate 12 can be protected and fixed in time by the automatic sealing and waterproof mechanism 4. The automatic sealing and waterproof mechanism 4 can not only stabilize the safe door, but also cause a certain amount of extrusion between the push plate 12 and the curved hammer door 11 through the rotation of the driving plate 41. Therefore, the triangular extrusion plate 24 can be squeezed again through the extrusion, so that the rubber pad 25 is driven by the extrusion of the triangular extrusion plate 24 to fit with the wall 1, thereby preventing the water leakage from occurring again.
