Detailed Description

In order to make the technical solution and the advantages of the present invention clearer, the following explains embodiments of the present invention in further detail.

Portable detachable security fence, including pole setting 100, treater, audible-visual alarm module, the upper portion of pole setting 100 is equipped with the telescopic band, connects through the telescopic band between two adjacent pole settings 100, during the use, pulls out the inside telescopic band of pole setting 100, and the joint block of telescopic band is in another pole setting 100 opening, and when not using, takes out the joint of telescopic band from the bayonet socket of another pole setting 100, and the inside of pole setting 100 is withdrawed to the telescopic band is automatic. In order to detect the used or pulled out stretchable band, a stretchable band dynamic monitoring device is disposed on the upper portion of the vertical rod 100. The dynamic monitoring device detects whether the telescopic belt is pulled or moved, the telescopic belt dynamic detection device 200 is electrically connected with the processor, when the telescopic belt dynamic detection device 200 detects that the telescopic belt is pulled, an alarm signal is sent to the processor, and the processor starts the sound-light alarm module to perform sound-light alarm. And then can be in time when someone climbs the telescopic band send alarm signal, suggestion operating personnel or managers someone gets into to in time make safeguard measure, reduce the safety risk.

Preferably, the telescopic strap dynamic detection device 200 is a travel switch, and the travel switch is disposed on the upper portion of the vertical rod 100. The travel switch is rotatably connected with the upper part of the upright 100 and is provided with a position locking mechanism.

One of the travel switches or position switches (also called limit switches) is a common low-current master control electrical appliance. The contact of the mechanical motion part is operated by the collision to realize the connection or disconnection of the control circuit, thereby achieving a certain control purpose. Generally, such switches are used to limit the position or stroke of the movement of the machine, so that the moving machine can automatically stop, move in reverse, shift or automatically move back and forth according to a certain position or stroke.

In an electric control system, a position switch is used for realizing sequential control, positioning control and position state detection. Used for controlling the stroke and the limit protection of mechanical equipment. The construction method comprises the following steps: consists of an operating head, a contact system and a shell.

In actual production, the travel switch is arranged at a prearranged position, and when a module arranged on a moving part of the production machine impacts the travel switch, the contact of the travel switch acts to realize the switching of a circuit. Thus, a travel switch is an electrical device that switches circuits depending on the travel position of a moving part, and functions in a manner similar to a push button.

The travel switch is widely used for various machine tools and hoisting machinery for controlling the travel and carrying out terminal limit protection. In the control circuit of the elevator, the speed of opening and closing the car door, the limit of automatically opening and closing the door, and the upper limit and the lower limit protection of the car are controlled by utilizing a travel switch.

The travel switch can be installed on relatively static objects (such as a fixed frame, a door frame and the like, which are called static objects for short) or moving objects (such as a travelling crane, a door and the like, which are called animals for short). When the animal approaches a stationary object, the linkage of the switch drives the contacts of the switch causing the closed contacts to open or the open contacts to close. The action of the circuit and the mechanism is controlled by the change of the on-off state of the switch contact.

When the telescopic belt is stretched to the other upright rod 100 and inserted into the other upright rod 100, the travel switch of the upright rod 100 where the telescopic belt is located is rotated to enable the trigger mechanism to be abutted against the telescopic belt, and when a person wants to climb over the telescopic belt, the telescopic belt is stretched to trigger the trigger mechanism of the travel switch, and then an alarm signal is sent.

Furthermore, in order to better detect the position movement of the telescopic belt, a through hole is formed in the middle of the telescopic belt. After the telescopic belt is stretched to another vertical rod 100 and inserted into another vertical rod 100, the travel switch of the vertical rod 100 where the telescopic belt is located is rotated to enable the trigger mechanism to be abutted to the telescopic belt, when a person wants to climb over the telescopic belt, the telescopic belt is stretched, the trigger mechanism of the travel switch is sunk into the through hole of the telescopic belt, the travel switch is triggered, and then an alarm signal is sent out.

The telescopic strap dynamic state detection device 200 may also employ a photoelectric detection module or an infrared correlation sensor. The infrared correlation is called as Active infrared intrusion detectors (Active infrared detectors), and the basic structure of the infrared correlation comprises a transmitting end, a receiving end, a light beam intensity indicator lamp, an optical lens and the like. The detection principle is that infrared rays emitted by an infrared light emitting diode are focused by an optical lens, so that the rays are transmitted to a long distance, and finally the rays are received by a photosensitive transistor at a receiving end. When an object blocks the infrared ray emitted by the emitting end, the receiving end can not receive the infrared ray, so that an alarm can be given. Infrared is an invisible light and is diffused and, after being projected, forms a cone beam in the initial path, the ideal intensity of which decays inversely square with the distance of emission as the distance of emission increases. When an object crosses its detection zone, the infrared beam is intercepted, causing an alarm. The traditional active infrared intrusion detector is usually used for alarming on outdoor enclosing walls because of the types of only two light beams, three light beams and four light beams. When the telescopic belt moves or stretches, the position of the through hole changes, so that the optical path can be shielded, and the function of position detection is realized.

By using the invention, an alarm signal can be sent out in time under the condition that someone turns over, and maintenance personnel can be prompted to process in time.

In summary, the present invention is only a preferred embodiment, and is not intended to limit the scope of the present invention, and various changes and modifications can be made by workers in the light of the above description without departing from the technical spirit of the present invention. The technical scope of the present invention is not limited to the content of the specification, and all equivalent changes and modifications in the shape, structure, characteristics and spirit described in the scope of the claims of the present invention are included in the scope of the claims of the present invention.
