[0033] The principles and features of the present utility model will be described below in conjunction with the accompanying drawings. The examples given are only used to explain the present utility model and are not intended to limit the scope of the present utility model.

[0034] As Figures 1 to 5 shown, a multi-angle climbing alarm mechanism of this embodiment is used on the two-section upright columns of the perimeter protection net; it includes an upper connecting plate 1, a lower connecting plate 2, an elastic guiding mechanism, an induction cup and an induction head. The upper connecting plate 1 is arranged parallel and at intervals above the lower connecting plate 2. The upper connecting plate 1 is used to connect the lower end of the upper upright column 51 of the two-section upright column, and the lower connecting plate 2 is used to connect the lower upright column 5 of the two-section upright column. The upper connecting plate 1 is installed on the lower connecting plate 2 through the elastic guiding mechanism and can displace relative to the lower connecting plate 2. The induction cup and the induction head are located between the upper connecting plate 1 and the lower connecting plate 2. The induction cup is insulated and installed on one of the upper connecting plate 1 and the lower connecting plate 2, and the induction head is insulated and installed on the other of the upper connecting plate 1 and the lower connecting plate 2. The induction head is placed in the cavity of the induction cup. Both the induction head and the induction cup are conductors. The induction cup is connected with a first wire 33, and the induction head is connected with a second wire 43. Among them, in the untriggered state, there is a gap reserved between the induction head and the inner side wall of the cavity of the induction cup. In the triggered state, the upper connecting plate 1 displaces, and the induction head contacts and conducts with the inner side wall of the cavity of the induction cup.

[0035] Among them, displacement means any movement that the upper connecting plate can make when the metal net connected to the two-section upright column is climbed and stressed, such as the upper connecting plate tilting or moving up and down, etc.

[0036] In the untriggered state, there is a certain distance between the induction cup and the induction head. The distance between the two is determined by the length of the guide rod and the specifications of the combined spring. The size of the spring and the size of the guide rod ensure that there is a certain spacing between the induction cup and the induction head, and they do not come into direct contact. Corresponding to the circuit, this is an open circuit state. This spacing can be adjusted by different specifications of the guide rod and the spring. Both ends of the induction cup and the induction head are connected with flexible wires for connection between multiple alarm mechanisms, and a layer of heat shrinkable tube or insulating material is sleeved outside. The main functions are insulation protection, waterproof and moisture-proof, and a certain degree of protection. The induction cup and the induction head do not contact each other usually, their sizes and distances are adjustable, and the materials are metal materials such as iron and copper.

[0037] As Figure 2 , Figure 4 and Figure 5 shown, the induction cup of this embodiment includes a first fixing plate 3 and a cup body 31. The cup body 31 is installed on the first fixing plate 3, and specifically, it can be installed and fixed by bolts; the first fixing plate 3 is installed insulatively on one of the upper connecting plate 1 and the lower connecting plate 2, and the cup body 31 is arranged vertically upward or downward.

[0038] As Figure 2 , Figure 4 and Figure 5 shown, the bottom of the cavity of this embodiment is a conical structure, and the side wall of the cavity is an annular structure. The cooperation of the conical structure and the annular structure is adopted to facilitate receiving the trigger of the induction head in all directions.

[0039] As Figure 2 , Figure 4 and Figure 5 shown, the induction head of this embodiment includes a second fixing plate 4 and a ball head 41. The ball head 41 is installed on the second fixing plate 4. Specifically, a connecting screw rod can be arranged on the ball head 41. The connecting screw rod can pass through the second fixing plate 4 and the second through hole 21 on the lower connecting plate, and then be locked by a nut on the side close to the ball head; the second fixing plate 4 is installed insulatively on the other of the upper connecting plate 1 and the lower connecting plate 2, and the ball head 41 is arranged vertically downward or upward. By setting the ball head, it is convenient to trigger the inner side wall of the cavity in all directions.

[0040] As Figure 2 , Figure 4 and Figure 5 shown, the induction cup of this embodiment is fixed on one of the upper connecting plate 1 and the lower connecting plate 2 by a first bolt 32, and insulation treatment is carried out between the first bolt 32 and the induction cup; the induction head is fixed on the other of the upper connecting plate 1 and the lower connecting plate 2 by a second bolt 42, and insulation treatment is carried out between the second bolt 42 and the induction head.

[0041] As Figure 2 , Figure 4 shown, a first through hole 11 penetrating up and down is formed in the upper connecting plate 1 of the present embodiment, and the first wire 33 or the second wire 43 passes through the first through hole 11; a second through hole 21 penetrating up and down is formed in the lower connecting plate 2, and the second wire 43 or the first wire 33 passes through the second through hole 21. By providing the through holes, it is convenient to pass the wires through the corresponding connecting plates.

[0042] As Figure 2 and Figure 3 shown, the elastic guiding mechanism of the present embodiment includes a guiding rod 6 and an elastic member. A guiding rod 6 is vertically connected to the upper surface of the lower connecting plate 2, and an elastic member is sleeved on the guiding rod 6. A guiding hole is formed in the upper connecting plate 1, and the upper end of the guiding rod 6 passes through the guiding hole and is limited by a limiting member 62. The elastic member is compressed between the upper connecting plate 1 and the lower connecting plate 2. Specifically, the elastic member can be a spring 61, silica gel, rubber, etc.

[0043] An alternative solution of the present embodiment is that the multi-angle climbing alarm mechanism further includes an alarm system, and the first wire 33 and the second wire 43 are respectively electrically connected to the alarm system. By providing the alarm system, the alarm information on site can also be timely uploaded to the upper computer by adding a corresponding switch quantity acquisition and transmission module, and the duty personnel can be informed in different ways such as terminal alarm, mobile phone text message or APP, so as to be safe and reliable and improve efficiency. When a person climbs, he must rely on force. Whether stepping on the wire mesh between the two two-section columns or pulling the Y fork or V net part of the column, there will be a certain gravity or pressure acting on the top Y fork of the Y-shaped column. Then, there will definitely be a downward or forward-backward force. As long as this force is large enough, regardless of the direction, the induction cup and the induction head inside the climbing alarm mechanism will change from separation to contact due to the displacement caused by the force, that is, the state changes from off to on. Through the remotely connected switch quantity acquisition module, the change in the electrical signal state is judged, and thus an alarm is issued.

[0044] The upper connecting plate 1 and the lower connecting plate 2 of the present embodiment can be made of iron plates, and the structure can be a rectangular structure, a circular structure, an oval structure, a polygonal structure, an irregular structure, etc. A protective housing 52 is further provided outside the upper connecting plate 1 and the lower connecting plate 2.

[0045] The multi-angle climbing alarm mechanism of this embodiment can be hidden in the two-stage column, which solves the disadvantage that the traditional solution is easily disturbed by the objective environment, is not affected and disturbed by wind, rain, snow, etc., and has a certain degree of concealment. When a person climbs and intrudes, whether it is stepping on the perimeter protection net or pulling the perimeter protection net (Y-fork, V-net, etc.), as long as the person's stepping force and pulling force are large enough, regardless of the direction of the force, the climbing alarm mechanism will be triggered, and the alarm can be issued in time and the information on the scene can be transmitted.

[0046] A perimeter protection device of this embodiment includes the above-mentioned multi-angle climbing alarm mechanism, and also includes a perimeter protection net and a two-stage column, the two-stage column is arranged vertically, and the perimeter protection net is connected to the two-stage column. Specifically, the perimeter protection net can be connected to the upper column and the lower column through a connecting piece. Since ordinary people will climb the perimeter protection net or pull the upper column, even if the lower column is also connected to the perimeter protection net through the connecting piece, it does not affect the displacement of the upper connecting plate caused by the perimeter protection net after being subjected to force.

[0047] Furthermore, the first wire and the second wire 33 and 43 are directly connected to the alarm system or are connected in series with the perimeter protection net and then connected to the alarm system, forming a protection monitoring system that sends out an alarm after climbing.

[0048] The perimeter protection device of this embodiment can be installed on a two-stage column. When a person steps on the wire mesh, a downward pulling force is generated, thereby compressing the spring as a whole, causing the upper sensing cup to move downward and contact the sensing head; when a person pulls the upper Y fork or V mesh, the Y fork generates a forward and backward (or biased) pulling force, which also compresses part of the spring, causing the sensing cup to move in a biased downward direction and contact the sensing head. The sensing cup and the sensing head each lead out a wire, which is connected to the remote switch quantity acquisition and transmission module. The contact between the sensing cup and the sensing head causes the wire to change from a disconnected state to a conductive state, thereby sounding an alarm.

[0049] The perimeter protection device of this embodiment can realize alarm monitoring of displacement at multiple angles and directions, and can monitor different types of climbing behaviors, without the need to add additional video monitoring equipment or on-site guards, thus saving costs. After the equipment is installed, no subsequent maintenance work is required, which also greatly saves labor costs.
