Technical Field

[0002] Electronic fence is an active intrusion prevention fence. The metal wires of traditional electronic fences tend to loosen after long-term use, and maintenance personnel are required to tighten the metal wires one by one, which is a cumbersome operation.

The utility model provides space for installation and adjustment of the tension-adjustable steel wire rope by means of a hollow area and a fine-tuning shaft arranged in the electronic fence pole. By rotating the fine-tuning shaft, the tightness of the tension-adjustable steel wire rope can be easily adjusted to achieve precise control of the tension of the fence, so that the fence system can adapt to different installation environments and protection requirements, and improve its applicability and flexibility. The design of the rotating disk makes the rotation operation of the fine-tuning shaft more convenient and intuitive. The user only needs to rotate the rotating disk to adjust the fine-tuning shaft, which is simple and quick to operate. The coordinated use of the limit pin and the limit socket can fix the position of the rotating disk.

[0004] The above device can adjust the tension of the metal wire, but manual direct operation of the fine-tuning shaft or rotating disk is still required during the adjustment process.

The winding roller 111 has a limiting groove 120, and the fan blade 106 is driven to rotate by wind force. The transmission component 107 transmits power to the rotating shaft 108, so that the rotating shaft 108 drives the fixed friction pad 109 to rotate, and then drives the rotating friction pad 110 and the winding roller 111 to rotate, so that the winding roller 111 tightens the tension line 104, thereby achieving the purpose of automatically tensioning the tension line 104. It can be understood that the above-mentioned scheme can be used for automatically tensioning the tension line 104, and can also be used for tensioning the tension line 104 when the tension conditions of each tension line 104 are different.

[0027] For this specific embodiment, the tension sensor 103 is installed inside the support column 101, the tension line 104 is arranged on one side of the tension sensor 103, two mounting columns 102 are arranged, and are respectively located on both sides of the support column 101, and multiple tension lines 104 are installed on one mounting column 102 through the tensioning assembly 105, and multiple tension sensors 103 are arranged, each of the tension lines 104 is connected to a tension sensor 103, and each of the tension sensors 103 is communicatively connected to a data processing unit, which is responsible for receiving and analyzing data from each of the tension sensors 103 to monitor the tension state of the tension line 104 in real time; when the tension of the tension line 104 is abnormal, the data processing unit will trigger the alarm system, and send an alarm to the security monitoring center through various methods such as sound, light and electricity, to ensure that urban security management personnel can respond quickly and deal with potential security threats. This part is the existing technology, and its working principle will not be described in detail here.

[0028] The rotating shaft 108 is rotatably connected to the mounting column 102 and is located inside the mounting column 102. The transmission component 107 is arranged on the mounting column 102. The fan blade 106 is connected to the rotating shaft 108 through the transmission component 107. The fixed friction pad 109 is fixedly connected to the rotating shaft 108 and sleeved on the rotating shaft 108. The winding roller 111 is rotatably connected to the rotating shaft 108 and is connected to the tension line 104 and sleeved on the rotating shaft 108. The rotating friction pad 110 is connected to the rotating shaft 108. The winding roller 111 is slidably connected and contacts the fixed friction pad 109, and is sleeved on the rotating shaft 108. The elastic component 112 is arranged on the winding roller 111. A plurality of the fixed friction pads 109, a plurality of the rotating friction pads 110 and a plurality of the winding rollers 111 are installed on one of the mounting columns 102. The transmission component 107 can transmit the power of the rotation of the fan blades 106 to the rotating shaft 108. The elastic component 112 is used to drive the rotating friction pad 110 to move toward the fixed friction pad 109.

[0029] When in use, one end of the tension line 104 is wound around the winding roller 111, and the other end of the tension line 104 is connected to the tension sensor 103. When it is windy outside, the wind blows the fan blade 106 to rotate, and the transmission component 107 outputs the power of the fan blade 106 to the rotating shaft 108, and drives the fixed friction pad 109 to rotate through the rotating shaft 108. Because the rotating friction pad 110 contacts the fixed friction pad 109 under the action of the elastic component 112, friction is generated between the fixed friction pad 109 and the rotating friction pad 110, thereby driving the winding roller 111 to rotate, so that the winding roller 111 can tighten the tension line 104, thereby achieving the purpose of automatically tightening the tension line 104 under the action of wind, thereby reducing labor costs.

[0030] Secondly, the wire baffle 113 is fixedly connected to the winding roller 111 and is sleeved on the winding roller 111; two wire baffles 113 are provided on one winding roller 111, and the two wire baffles 113 are respectively located on both sides of the tension line 104, and the tension line 104 is limited by the wire baffle 113 to prevent the tension line 104 from being separated from the winding roller 111.

[0031] Meanwhile, the gear box 114 is connected to the mounting column 102 and is located at the top of the mounting column 102 , and the output end of the gear box 114 is connected to the rotating shaft 108 ; the connecting shaft 115 is connected to the input end of the gear box 114 .

[0032] In addition, the housing 116 is connected to the gear box 114 and is arranged on the gear box 114; the driven bevel gear 118 is fixedly connected to the connecting shaft 115 and is located at the top of the connecting shaft 115; the driving bevel gear 117 is rotationally connected to the housing 116, meshes with the driven bevel gear 118, and is fixedly connected to the fan blade 106.

[0033] When the fan blade 106 rotates, it drives the active bevel gear 117 to rotate, and the active bevel gear 117 drives the driven bevel gear 118 to rotate, so that the driven bevel gear 118 drives the connecting shaft 115 to rotate, and the connecting shaft 115 transmits power to the gear box 114; the gear box 114 is provided with a gear set and a ratchet structure inside, the gear set is used to reduce the rotation speed and increase the torque, and the ratchet structure allows the rotating shaft 108 to rotate in only one direction, so as to prevent the wind from blowing the fan blade 106 to rotate in the opposite direction and causing the rotating shaft 108 and the winding roller 111 to reverse.

[0034] Finally, there are multiple limiting protrusions 119, which are arranged on the peripheral side of the rotating friction pad 110; the winding roller 111 has a limiting groove 120, and the limiting groove 120 cooperates with the limiting protrusion 119; the limiting groove 120 is used to limit the limiting protrusion 119 to avoid relative rotation between the rotating friction pad 110 and the winding roller 111.

[0035] When using the tension safety protection electronic fence for smart cities of this embodiment, when the wind blows the fan blade 106 to rotate, the fan blade 106 drives the active bevel gear 117 to rotate, and the active bevel gear 117 drives the driven bevel gear 118 to rotate, thereby driving the connecting shaft 115 to rotate, and the connecting shaft 115 outputs power to the gear box 114, and the gear box 114 outputs power to the rotating shaft 108, thereby driving the fixed friction pad 109 to rotate. Due to the friction between the fixed friction pad 109 and the rotating friction pad 110, the rotating friction pad 110 can drive the winding roller 111 to rotate, so that the winding roller 111 collects the tension line 104, thereby automatically tensioning the tension line 104.

The tensioning assembly 105 of this embodiment further includes a locking member 201 . The locking member 201 includes a ratchet 202 , a pawl 203 and an abutting spring 204 .

[0038] According to this specific embodiment, the ratchet 202 is fixedly connected to the rotating shaft 108, and is sleeved on the rotating shaft 108 and is located inside the winding roller 111; the pawl 203 is rotationally connected to the winding roller 111 and is located inside the winding roller 111; the two ends of the abutment spring 204 are respectively connected to the winding roller 111 and the pawl 203; the abutment spring 204 applies force to the pawl 203, so that the pawl 203 contacts the ratchet 202, and the ratchet 202 and the pawl 203 prevent the winding roller 111 from rotating in the opposite direction on the rotating shaft 108, which causes the tension line 104 to loosen.

The driving component 303 includes a driving seat 305, a connecting rod 306, a pressure block 307 and a second spring 308.

[0041] Among them, the lifting seat 302 is slidably connected to the winding roller 111 and is located inside the winding roller 111; the two ends of the first spring 301 are respectively connected to the lifting seat 302 and the rotating friction pad 110; the driving component 303 is arranged on the winding roller 111; the first spring 301 applies force to the rotating friction pad 110, so that the rotating friction pad 110 contacts the fixed friction pad 109, so that the rotation of the fixed friction pad 109 can drive the rotating friction pad 110 to rotate.

[0042] Secondly, the guide rod 304 is fixedly connected to the winding roller 111 and slidably connected to the lifting seat 302, and is located inside the winding roller 111; the movement of the lifting seat 302 is guided by the guide rod 304 to improve the stability of the lifting seat 302 when it is lifted or lowered.
