Description

Technical Field

[0001] The invention belongs to the technical field of security equipment, and specifically relates to a security access control device for a residential area. Background Art

[0002] Nowadays, automatic lifting fences are usually installed at the entrance of residential communities, and are equipped with automatic license plate recognition systems. The license plate recognition system is usually connected to auxiliary systems such as billing systems. When the system recognizes that the vehicle is a registered vehicle, it can automatically lift and open. When the vehicle is recognized as an unregistered vehicle, it can also be recorded in the file. The parking fee can be reasonably calculated based on the entry time and exit time, which is convenient for the management of vehicles entering and leaving the community. At the same time, it can effectively prevent private vehicles from entering at will, which is convenient for community security management.

[0003] Existing automatic lifting fences usually open or close by rotating and lifting in a vertical plane. In addition, the system recognition time is usually long. When an emergency occurs, such as a fire or someone in the community needs first aid, it cannot be opened quickly and in time, causing the fire truck or ambulance to start and stop at the access control, wait for identification, and need to be delayed at the access control for more than ten seconds or more. In the face of such unexpected emergencies, one second may cause huge losses, so the time wasted at the access control is particularly important.

[0004] In view of this, the present invention is proposed to solve the above technical problems. Summary of the invention

[0005] The purpose of the present invention is to provide a security access control device for a residential area. The specific problem to be solved by the present invention is that the existing automatic lifting fence gates are usually opened or closed by rotating and lifting in a vertical plane. In addition, the system recognition time is usually long. When an emergency occurs, rescue vehicles cannot enter quickly and need to wait at the access control for more than ten seconds or even longer, which may miss the best rescue opportunity and cause immeasurable losses.

[0006] To achieve the above object, the present invention provides the following technical solutions:

The electromagnet has the same outer diameter as the positioning sleeve. The positioning sleeve and the electromagnet are elastically connected through small springs. The number of the small springs is greater than one, and the small springs are equidistantly distributed in a circle.

[0014] The positioning sleeve is made of ductile iron and sprayed with anti-rust paint on the inner and outer surfaces;

[0015] A sliding sleeve is arranged in the middle of the main rod, and the sliding sleeve is used to limit the positioning sleeve.

[0016] Preferably, the small spring enables the positioning sleeve to completely wrap the hinged joint in a natural state.

[0017] Preferably, a spring box is installed at one end of the main cross bar away from the base and close to the base, a cylindrical groove is opened on one side of the spring box close to the base, and the main bar is elastically connected to the bottom surface of the groove through a large spring;

[0020] The electrode rods on the inner wall of the spring box are connected in parallel through a circuit embedded in the spring box.

[0021] Preferably, the elastic coefficient of the large spring must satisfy the requirement that it can support the normal lifting of the main cross bar and the secondary cross bar when the fence is lifted and lowered normally only by gravity, and the horizontal swing caused by the generated vibration is not sufficient to cause the electrode on the main bar to contact the electrode rod in the spring box.

When an emergency vehicle passes by, the audible and visual alarm can also warn the security personnel to respond in time, which is convenient for subsequent arrangements. At the same time, it can also warn nearby personnel to evacuate or avoid in time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0036] The embodiment of the present invention provides a security access control device for a residential area, thereby solving the technical problem that the existing automatic lifting fence door usually adopts the method of rotating and lifting in a vertical plane to open or close, and the system recognition time is usually long. When an emergency occurs, rescue vehicles cannot enter quickly and need to wait at the access control for more than ten seconds or even longer, which may miss the best rescue opportunity and cause immeasurable losses.

[0037] The technical solution in the embodiment of the present invention is to solve the above-mentioned technical problems. The overall idea is as follows: by designing the main cross bar and the secondary cross bar of the fence as a structure that can be opened and closed in the horizontal direction, and adding a trigger, when a vehicle needs to pass urgently, it only needs to pass slowly without stopping to be identified, thereby reducing the time it takes for the vehicle to pass through the fence.

[0038] To better understand the technical solution of the present invention, please refer to Figures 1 to 6 In an embodiment of the present invention, a security access control device for a residential area includes an electric lifting fence, the electric lifting fence includes a base 1, a main crossbar 2, a secondary crossbar 3 and a connecting rod 4, a power system is installed in the base 1, the number of connecting rods 4 is greater than one, one end of the main crossbar 2 and the secondary crossbar 3 is hinged on the base 1, and the main crossbar 2 and the secondary crossbar 3 are hinged through the connecting rod 4;

[0039] An emergency escape device 5 is provided on one side of the main crossbar 2 and the secondary crossbar 3 close to the base 1, which is used to change the opening direction of the fence as a whole;

[0040] The main cross bar 2 and the secondary cross bar 3 are both divided into two sections and connected by an emergency avoidance device 5.

[0041] By adding the emergency avoidance device 5, when the community encounters an emergency and rescue vehicles arrive, there is no need to stop and wait in front of the fence, and the speed can be reduced to continue to drive forward. Under the action of the emergency avoidance device 5, when the main cross bar 2 and the secondary cross bar 3 are subjected to a certain thrust in the horizontal direction, the emergency avoidance device 5 will enable the entire fence to rotate and open in the horizontal direction, and open to one side under the thrust of the front of the vehicle; through the setting of the emergency avoidance device 5, the rescue vehicles of the emergency event do not have to stop at the gate and wait for the fence to open. Compared with the existing electric lifting fence that only has the function of opening in the vertical plane, the time required for the rescue vehicle to pass the gate is reduced, the convenience of rescue is increased, and the protection of the life and property safety of the people in the community is improved.

[0042] As an embodiment of the present invention, a section of the main crossbar 2 and the secondary crossbar 3 close to the base 1 and an end away from the base 1 are provided with a hinge joint 6, and are hinged to the emergency escape device 5;

[0043] The hinge rod 61 at the hinge joint 6 is arranged vertically;

[0044] Setting the hinge rod 61 at the hinge joint 6 vertically can ensure that when the fence is subjected to stress, under the action of the emergency avoidance device 5, the entire fence can be accurately opened in the horizontal direction, thereby preventing the main cross bar 2 or the secondary cross bar 3 from generating stress to counteract the external thrust and causing the main cross bar 2 or the secondary cross bar 3 to break.

[0045] As an embodiment of the present invention, the emergency avoidance device 5 includes a main rod 51, and the left end of the main rod 51 is hinged to the hinge head 6;

[0046] A positioning sleeve 52 is slidably connected to the outside of the main rod 51, and a ring-shaped electromagnet 53 is fixedly connected to the middle of the main rod 51. The electromagnet 53 has the same outer diameter as the positioning sleeve 52. The positioning sleeve 52 and the electromagnet 53 are elastically connected through small springs 54. The number of small springs 54 is greater than one, and the small springs 54 are equidistantly distributed in a circle.

[0047] The positioning sleeve 52 is made of ductile iron and sprayed with anti-rust paint on the inner and outer surfaces;

[0048] A sliding sleeve 55 is provided in the middle of the main rod 51, and the sliding sleeve 55 is used to limit the positioning sleeve 52;

[0049] As an embodiment of the present invention, the small spring 54 enables the positioning sleeve 52 to completely wrap the hinged joint 6 in a natural state;

[0050] When the present invention is in normal working state, under the action of the small spring 54, the positioning sleeve 52 is always located at the position completely wrapping the position of the hinge head 6. At this time, under the action of the positioning sleeve 52, the hinge head 6 cannot move. Therefore, driven by the power system, the fence as a whole can do lifting and lowering movement around the hinge point of the base 1 in the vertical plane to achieve normal opening and closing, and will not lose the center of gravity and cause danger due to the setting of the hinge point; when an emergency occurs, the electromagnet 53 is energized and magnetic, and the positioning sleeve 52 is adsorbed. At this time, the hinge point of the main cross bar 2 and the secondary cross bar 3 is exposed. When the emergency rescue vehicle passes, the rescue vehicle pushes the cross bar as a whole to open in the horizontal direction. During this process, the emergency rescue vehicle does not need to slow down, thereby achieving the effect of reducing the time it takes for the rescue vehicle to pass; the positioning sleeve 52 is made of ductile iron, and anti-rust paint is sprayed on the inner and outer surfaces. On the one hand, it can be affected by the magnetic force of the electromagnet 53 to achieve the function of the positioning sleeve 52. On the other hand, it can reduce the rust of the positioning sleeve 52, increase the service life of the positioning sleeve 52, and reduce maintenance costs.

[0051] As an embodiment of the present invention, a spring box 56 is installed at one end of the main cross bar 2 away from the base 1 and close to the base 1. A cylindrical groove 561 is opened on one side of the spring box 56 close to the base 1. The main rod 51 is elastically connected to the bottom surface of the groove 561 through a large spring 57.

[0052] Electrode rods 562 are arranged on both sides of the inner wall of the groove 561, and an electrode sheet 511 is embedded in the surface of one end of the main rod 51 away from the base 1. The electrode sheet 511 and the electrode rod 562 can contact when the spring is bent;

[0053] As an embodiment of the present invention, a battery 58 is embedded in the main rod 51, one end of the battery 58 is connected to the electromagnet 53, and the other end is connected to the electrode sheet 511 on one side, and the electrode sheet 511 on the other side is connected to the electromagnet 53;

[0054] The electrode rods 562 on the inner wall of the spring box 56 are connected in parallel through the circuit embedded in the spring box 56;

[0055] The spring box 56 is elastically connected to the main rod 51 through a large spring 57. Through the cooperation of the electrode sheet 511 and the electrode rod 562, the connection plays a role similar to that of a switch. When the fence body is pushed to a certain force and the fence is offset at a certain angle relative to its original position, the electrode sheet 511 contacts the electrode rod 562, thereby connecting the circuit in the main rod 51, thereby starting the electromagnet 53 and attracting the positioning sleeve 52. In this way, under the thrust of the rescue vehicle on the fence itself, the fence can be opened horizontally to one side, thereby realizing the function of the emergency avoidance device 5.

[0056] As an embodiment of the present invention, the elastic coefficient of the large spring 57 needs to satisfy that when the fence is normally lifted and lowered only by gravity, it can support the normal lifting and lowering of the main crossbar 2 and the secondary crossbar 3, and the horizontal swing caused by the generated vibration is not enough to make the electrode on the main rod 51 contact with the electrode rod 562 in the spring box 56;

[0057] The limitation on the elastic coefficient of the large spring 57 ensures, on the one hand, that when the fence is working normally, its vibration will not cause the circuit in the main rod 51 to be connected and the positioning sleeve 52 to withdraw from the position of the hinge joint 6, thereby causing the overall center of gravity of the fence to shift during the lifting and lowering process of the fence and causing danger. On the other hand, the design of the large spring 57 can also play a certain shock-absorbing role on the entire fence, thereby reducing the influence of stress and increasing the fatigue life of the main cross bar 2 and the secondary cross bar 3.

[0058] As an embodiment of the present invention, a semi-circular solar panel 59 is embedded in the upper surface of the main rod 51 that is exposed to the air, and the solar panel 59 is connected in series with the battery 58;

[0059] By setting up the solar panel 59, the electromagnet 53 can be supplied with electricity during the day and the battery 58 can be charged to ensure that the emergency escape device 5 is available 24 hours a day and avoid failure of the emergency escape device 5 due to power outages. At the same time, the use of the solar panel 59 can also save the step of charging the battery 58, making the emergency escape device 5 self-sufficient and improving convenience.

[0060] As an embodiment of the present invention, the main crossbar 2, the secondary crossbar 3, the connecting rod 4 and the main rod 51 are all made of carbon fiber material and are sprayed with insulating paint on the surface;

[0061] Using carbon fiber as the main material of the fence can, on the one hand, reduce the overall weight of the fence, thereby reducing the burden on the power system, and on the other hand, it can also enhance the strength of the fence, thereby improving the safety and reliability of the deployed fence. At the same time, the main pole 51 is made of carbon fiber material, which can also avoid affecting the work of the electromagnet 53, thereby affecting the work of emergency avoidance.

[0062] As an embodiment of the present invention, a sound and light alarm 7 is fixedly connected to a section of the upper surface of the main crossbar 2 close to the base 1 and is connected in series with the battery 58;

[0063] The sound and light alarm 7 is connected in series with the battery 58. When a vehicle maliciously uses the emergency avoidance device 5 to break through, it will provide a sound and light alarm to remind the security personnel, so that they can deal with it in time. When an emergency vehicle passes by, the sound and light alarm can also warn the security personnel to respond in time, which is convenient for subsequent arrangements. At the same time, it can also warn nearby people to evacuate or avoid in time.

[0064] Working principle: Under normal working conditions, under the action of the small spring 54, the positioning sleeve 52 of the present invention is always located at a position that completely wraps the position of the hinge 6. At this time, under the action of the positioning sleeve 52, the hinge 6 cannot move. Therefore, driven by the power system, the fence as a whole can do lifting and lowering movements around the hinge point of the base 1 in the vertical plane to achieve normal opening and closing without losing the center of gravity and causing danger due to the setting of the hinge point. When the community encounters an emergency and the rescue vehicle arrives, it is not necessary to stop in front of the fence and wait, but to reduce the speed and continue to drive forward. Under the action of the emergency avoidance device 5, when the fence body is subjected to a certain force of thrust and causes the fence to be offset by a certain angle relative to its original position, When the electric field is opened, the electrode sheet 511 contacts the electrode rod 562, so that the circuit in the main rod 51 is connected, thereby starting the electromagnet 53 and attracting the positioning sleeve 52. At this time, the hinge point between the main cross bar 2 and the secondary cross bar 3 is exposed. When the emergency rescue vehicle passes by, the thrust causes the fence to open horizontally as a whole, thereby achieving the effect of reducing the time it takes for the rescue vehicle to pass through. At the same time, the present invention is provided with an audible and visual alarm 7. When a vehicle maliciously uses the emergency avoidance device 5 to break through, an audible and visual alarm will be provided to prompt the security personnel, so that timely disposal is convenient. When an emergency vehicle passes by, the audible and visual alarm can also warn the security personnel to respond in time, which is convenient for subsequent arrangements. At the same time, it can also warn nearby personnel to evacuate or avoid in time.

[0065] The technical features of the above embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not exist, the above embodiments only express several implementation methods of the present invention. The description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present invention, several variations and improvements can be made, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
