Description

Technical Field

[0001] The present invention relates to the technical field of bank security construction, in particular to a security construction device for a wall-penetrating air duct. Background Art

[0002] The field of bank security technology primarily encompasses physical and technical defense. In terms of physical defense, bank buildings generally utilize sturdy construction materials, with walls and ceilings designed to withstand impact, fire, and explosions. Bank exterior walls are typically constructed from sturdy reinforced concrete, a material known for its strength and durability. These materials are often thicker than ordinary building walls, allowing them to withstand significant impact. Internally, some banks employ multiple layers of protection, such as metal mesh or steel plates in key areas. These internal layers enhance the walls' resistance to vandalism, particularly effectively deterring attempted break-ins.

[0003] However, the ventilation ducts that pass through the wall are the weak points of the wall protection. The air ducts are generally made of strong materials, such as metal, to prevent them from being easily damaged. At the same time, where the air ducts pass through the walls of key protection areas (such as vaults, cash business areas, etc.), in order to prevent illegal entry and damage, a protective net is generally installed inside the air duct for protection. Currently, the most common connection method between the metal net and the air duct is to directly pass through the air duct with threaded steel bars with a nominal diameter of ≥16, and the grid spacing is ≤100mm×100mm, which is effectively fixed to the wall. However, if the air duct passes through steel bars, the air tightness of the air duct will be seriously affected, and the steel bars passing through the air duct are difficult to fix to the wall. Since the mesh of the protective net is large, not only may illegal personnel use the gap between the air duct and the wall to carry out destructive activities or eavesdropping, but the dust-proof effect is poor, and it is difficult to protect against some animals such as insects and rats. Although the existing technology can reduce the entry of insects and rats by placing insect repellents, the insect repellents have a strong smell. If they are placed near the air duct for a long time, it will affect the smell of ventilation. Moreover, they evaporate quickly and need to be replaced frequently. In addition, some insects and rats will still enter despite being afraid of the smell, making the insect and rat prevention effect of the entire air duct poor. Moreover, when the protective net is damaged, it is difficult to issue an alarm in time. After long-term use, some dust will adhere to the surface of the protective net, which is not convenient to clean. Long-term use will affect the ventilation effect of the air duct. Therefore, it is of great significance to study a new security construction device for through-wall air ducts to solve the above problems. Summary of the Invention

[0004] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract and title of this application to avoid obscuring the purpose of this section, the abstract and the title of the invention, and such simplifications or omissions should not be used to limit the scope of the present invention.

[0005] In view of the above-mentioned and / or existing problems in bank security construction, the present invention is proposed.

[0006] Therefore, the technical problem to be solved by the present invention is that the current common connection method between the metal mesh and the air duct will seriously affect the air tightness of the air duct, and the steel bars passing through the air duct are difficult to fix to the wall. Since the mesh of the protective net is large, not only may illegal personnel use the gap between the air duct and the wall to carry out destructive activities or eavesdrop, but the dust-proof effect is poor, and it is difficult to protect against some animals such as insects and rats. Moreover, when the protective net is damaged, it is difficult to issue an alarm in time.

[0014] As a further solution of the present invention: pressure sensors are installed in both inner cavities of the collection box, a partition is provided above the pressure sensor, and two side doors are provided on both sides of the collection box.

[0015] As a further solution of the present invention: the flip assembly includes a flip screen, which is hinged in the bottom cavity through a pin shaft, and torsion springs are fixed on both sides of the flip screen, and the two torsion springs are fixed to the two side walls of the bottom cavity with one end away from each other.

[0016] As a further solution of the present invention: the wire transmission assembly includes a motor, the motor is installed in a housing, and the output shaft of the motor is fixedly connected to the second wire wheel.

[0017] As a further solution of the present invention: the elastic component includes two guide rods, which are fixedly connected to the retaining plate, and both ends of the guide rods are fixedly connected to the first springs, and the two first springs are fixedly connected to the disc, and the disc slides on the guide rods, and a first wire wheel is rotatably connected between the two discs, and the wire blocking line passes around the first wire wheel, the second wire wheel and the guide wheel, and the guide wheel is installed on a pair of retaining plates above.

[0018] As a further solution of the present invention: an extension rod is fixedly connected to one side of the disc, and the two discs are fixed to the two ends of the two brackets, and the middle of the bracket corresponds to the switch.

[0019] As a further solution of the present invention, the adjustable shielding assembly includes a special-shaped cylinder, which is installed on the ventilation pipe. A first piston rod and a second piston rod are provided inside the special-shaped cylinder. The first piston rod extends out of the special-shaped cylinder and is fixedly connected to a support plate, and the support plate is located below the end of the extension rod. The second piston rod passes through the special-shaped cylinder and is fixed to a mesh layer. The mesh holes of the mesh layer and the mesh holes of the mesh box are staggered to maintain a seal. The mesh layer slides on the guide rail frame and overlaps below the mesh box.

[0020] The guide rail frame is fixed in the ventilation pipe, and a second spring is fixed on the inner wall of the guide rail frame, and one end of the second spring is fixed to the grid layer.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The security construction device for the through-wall air duct forms a grid structure by circulating the blocking wire up and down and passing through two sets of wire guide wheels in sequence, thereby filtering the air in the ventilation duct. When dust accumulates on the blocking wire, the second wire wheel is driven to rotate by the motor, so that the second wire wheel can drive the blocking wire to move, so that the blocking wire can be automatically cleaned when passing through the ridge. The cleaned impurities can enter the collection box along the ridge and the grid plate for collection and processing, thereby automatically cleaning the blocking wire and ensuring a good ventilation effect. When the blocking wire is damaged, the elastic component resets upward to trigger the switch, causing the alarm to sound, so that personnel can discover it in time, thereby improving safety.

[0023] 2. The security construction device for the through-wall air duct has a tight grid structure formed by the blocking wire, which can intercept insects and rodents. When the blocking wire is pulled by the insects and rodents, the force is transmitted to the elastic component, which applies pressure to the support plate, causing the first piston rod to move. The air pressure drives the second piston rod and the grid layer to move, causing the grid layer and the mesh of the net box to be staggered. At this time, the irritating drug in the net box emits an odor, thereby repelling insects and rodents. If an animal crosses the blocking wire, it passes through the flip component, which flips over and locks the mouse in the collection box. This method can provide multi-layer protection and minimizes harm to animals.

[0024] 3. The security construction device for the through-wall air duct can initially play the role of preventing insects and rodents through the grille structure formed by the blocking wire. When the blocking wire is subjected to force, the adjustable shielding component can be displaced by pressing down the elastic component, thereby opening the net box, thereby further driving away insects and rodents through the smell emitted by the pungent odor drug. After the animal crosses the blocking wire, it can fall into the trap by flipping the flip component, thereby preventing the animal from going deep into the ventilation duct. At the same time, the sound of the animal falling into the trap can drive away nearby animals. When the pressure sensor detects that an animal has fallen or a lot of dust has accumulated in the collection box, it will also sound an alarm to drive away nearby animals again. At the same time, the wire transmission component drives the blocking wire to slide on the raised part for cleaning to maintain cleanliness. In addition, the combination of these methods can effectively reduce the hiding places of insects and rodents in the ventilation duct.

[0025] 4. The security construction device of the through-wall air duct is buried in the longitudinal wall through angle steel, and the angle steels on both sides are tightly combined by bolt connection to form a solid overall structure, which improves the structural stability of the ventilation duct and improves the overall system's ability to resist external forces. The longitudinal and transverse threaded steels form a protective net structure, which can effectively disperse the impact force when hit by external forces, further ensuring the safety of high-security places such as banks. Secondly, the L-shaped design of the angle steel makes the bolt cap located on the inner side of the angle steel, further increasing the difficulty of removing the bolt, thereby preventing external forces from easily removing the device and ensuring the long-term stability and safety of the ventilation duct system. Even if the bolt cap is removed, the protective net cannot be removed. This design effectively prevents criminals from damaging the device by disassembling it, thereby ensuring the safety of facilities such as banks. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the irritating medicine in the net box 304 emits an odor, which can drive away insects and rats. If the animal crosses the blocking line 305 and the rat passes through the flip mesh plate 2062, the flip mesh plate 2062 will automatically flip over, causing the animal to fall into the collection box 2051, and the torsion spring 2061 drives the flip mesh plate 2062 to flip and reset to lock the rat in the collection box 2051. This method can serve as a multi-layer protection measure and try not to harm the animal.

[0057] The interception mechanism 300 includes a housing 301, an alarm 302 is installed on the housing 301, a switch 303 is installed at the bottom of the alarm 302, and two net boxes 304 are installed in the ventilation pipe 201 inside the housing 301. An adjustable shielding component 307 is provided below the net box 304. The two adjustable shielding components 307 correspond to the two ends of the elastic component 306. The elastic component 306, the two sets of wire guide wheels 309 and the wire transmission component 308 are wound with the same intercepting wire 307. 5. The two sets of wire guide wheels 309 are rotatably connected to the two pairs of retaining plates 310 respectively. The two pairs of retaining plates 310 are respectively fixed in the middle bottom cavity 204 and above the ventilation pipe 201, and the upper and lower walls of the ventilation pipe 201 are provided with raised portions 311, wherein the two bottom cavities 204 are located on both sides of the raised portions 311. Since the two sets of wire guide wheels 309 are distributed up and down, the wire blocking wire 305 passes through the two raised portions 311 up and down to form a grid structure. The number of each set of wire guide wheels 309 is multiple.

[0058] In this embodiment: the blocking wire 305 circulates up and down and passes around the two sets of wire guide wheels 309 in turn, so that the blocking wire 305 forms a grid structure, which can filter the air in the ventilation pipe 201, and when dust accumulates on the blocking wire 305, the second wire wheel 3082 is driven to rotate by the motor 3081, so that the second wire wheel 3082 can drive the blocking wire 305 to move, so that the blocking wire 305 can be automatically cleaned when passing through the raised portion 311, and the cleaned impurities can enter the collection box 2051 along the raised portion 311 and the grid plate 313 for collection and processing, so that the blocking wire 305 can be automatically cleaned and a good ventilation effect can be guaranteed. When the blocking wire 305 is damaged, the elastic component 306 resets upward to touch the switch 303, causing the alarm 302 to sound an alarm, so that personnel can discover it in time, thereby improving safety.

[0059] The working principle of the present invention is as follows: when cleaning the intercepting wire 305, the second wire wheel 3082 is driven to rotate by the motor 3081, and the second wire wheel 3082 drives the intercepting wire 305 to move, so that the intercepting wire 305 is transmitted in the raised portion 311, so that the raised portion 311 cleans impurities on the surface of the intercepting wire 305. After cleaning, the impurities pass through the raised portion 311 and the grid plate 313 into the collection box 2051 for collection;

[0060] When an animal enters the ventilation duct 201, the animal exerts force on the barrier line 305, causing the force of the barrier line 305 to act on the first wire wheel 3066, causing the first wire wheel 3066 to drive the disc 3064 downward, causing the extension rod 3061 to press the support plate 3073 downward. The support plate 3073 drives the first piston rod 3072 downward, causing the first piston rod 3072 to press the gas toward the other end of the special-shaped cylinder 3071. The gas pressure controls the movement of the second piston rod 3074, which drives the mesh layer 3076 to move. The mesh holes of the mesh layer 3076 are staggered with the mesh holes of the mesh box 304. At this time, the drug with a pungent smell in the mesh box 304 drives the animal away.

[0061] When the barrier 305 is damaged by an animal or by human beings, the first spring 3062 drives the disc 3064 to return upward, causing the bracket 3065 to press the switch 303 upward. At this time, the switch 303 controls the alarm 302 to sound an alarm.

[0062] When the animal crosses the barrier line 305, the animal walks onto the flip screen 2062, causing the flip screen 2062 to flip under force, causing the animal to automatically fall into the inner cavity on the other side of the collection box 2051, and the pressure sensor 2053 is alarmed by the pressure control alarm 302, so that personnel can perform maintenance work.
