[0020] 4. The present invention sets an electromagnet, which will generate magnetism after being energized. After generating magnetism, the electromagnet will generate a certain magnetic field in the surrounding area. The magnetic field has the effect of driving away birds, which is beneficial to prevent birds from stopping on the beam. On the one hand, it can reduce the probability of bird droppings on the fan-shaped plate, and on the other hand, it can also prevent pedestrians from being affected by birds when they are resting on the fan-shaped plate.

The base 1 is provided with a plurality of holes for wiring, which are used to connect the lines pre-laid underground in the community to the cable trough 18, thereby achieving the purpose of deploying surveillance cameras 8 in the community.

[0038] As a further implementation scheme of the present invention, four slide rails 30 are fixedly connected to the outer wall of the bottom end of the support column 4, a sliding groove 33 is opened at one end of the fan-shaped plate 3, and the sliding groove 33 is slidably connected to the slide rail 30.

[0039] In the specific implementation, the cross-sections of the slide rail 30 and the slide groove 33 are both "T"-shaped. The slide rail 30 and the slide groove 33 are slidably connected to make the fan-shaped plate 3 and the support column 4 at a right angle. The fan-shaped airbag 2 arranged at the bottom of the fan-shaped plate 3 supports the fan-shaped plate 3, thereby preventing the support column 4 from tipping over.

The rectangular column 11 is fixedly connected to the base 1, and limiting grooves 32 are provided on both sides of the rectangular column 11. The two limiting blocks 31 between the two adjacent fan-shaped plates 3 are respectively slidably connected in the limiting grooves 32 on both sides of the rectangular column 11.

[0041] In a specific implementation, the limiting blocks 31 are fixedly connected to the side walls of both sides of the sector plate 3, a gap is reserved between the limiting blocks 31 on two adjacent sector plates 3, and the wall panels between the limiting grooves 32 opened on both sides of the rectangular column 11 are located in the gap.

[0042] As a further implementation scheme of the present invention, four built-in air cylinders 22 are provided inside the base 1, and the four built-in air cylinders 22 are respectively located directly below the four fan-shaped plates 3. A piston plate 25 is slidably connected inside the built-in air cylinder 22, and a piston rod 24 is fixedly connected to the top of the piston plate 25. The piston rod 24 passes through the top wall plate of the base 1, and the piston rod 24 is fixedly connected to the fan-shaped plate 3. A hole groove is provided at the inner center of the fan-shaped airbag 2, and the piston rod 24 is slidably connected in the hole groove. The top of the piston rod 24 abuts against the fan-shaped plate 3, and a return spring 23 is fixedly connected to the bottom of the piston plate 25. The end of the return spring 23 away from the piston plate 25 is fixedly connected to the inner bottom wall plate of the built-in air cylinder 22.

[0043] In a specific implementation, a sealing ring is provided on the side of the piston plate 25, and the sealing ring abuts against the inner wall of the built-in gas cylinder 22 to prevent gas leakage. The return spring 23 is used to lift the sector plate 3. When the return spring 23 is compressed, the return spring 23 will have a tendency to lift.

[0044] As a further implementation scheme of the present invention, the top of the built-in air cylinder 22 is connected to a third air pipe 28, and the end of the third air pipe 28 away from the built-in air cylinder 22 is connected to the internal chamber of the fan-shaped airbag 2, and a one-way air outlet valve is provided at the connection between the built-in air cylinder 22 and the third air pipe 28. A fourth air pipe 29 is connected to one side of the top of the built-in air cylinder 22, and the end of the fourth air pipe 29 away from the built-in air cylinder 22 is connected to the outside atmosphere, and a one-way air inlet valve is provided inside the fourth air pipe 29. The four fan-shaped airbags 2 are respectively inflated through the four built-in air cylinders 22.

[0045] In a specific implementation, the one-way air outlet valve can only allow the gas in the built-in air cylinder 22 to flow into the fan-shaped airbag 2, and the one-way air inlet valve can only allow the air in the outside atmosphere to enter the built-in air cylinder 22. The fourth air pipe 29 and the second air pipe 27 are both provided with arc tubes at one end away from the built-in air cylinder 22, and the air inlet end of the arc tube faces downward, which is used to prevent rainwater from entering the built-in air cylinder 22 in rainy weather.

[0046] It should be noted that the fan-shaped airbag 2 is used to support the fan-shaped plate 3. As the fan-shaped airbag 2 is used for a long time, the gas inside it will be lost. Therefore, the built-in air cylinder 22 is used to replenish the gas, so the fan-shaped airbag 2 does not need to discharge the gas inside it.

[0047] As a further implementation scheme of the present invention, a clamping airbag 17 is provided on the top of the base 1, and the clamping airbag 17 is embedded in the inner top wall panel of the circular groove, and the bottom of one of the built-in air cylinders 22 is connected with a first air pipe 26 and a second air pipe 27, and the end of the first air pipe 26 away from the built-in air cylinder 22 is connected to the clamping airbag 17, and the end of the second air pipe 27 away from the built-in air cylinder 22 is connected to the outside atmosphere, an air outlet one-way valve is embedded in the first air pipe 26, an air inlet one-way valve is provided in the second air pipe 27, and a pressure relief valve is provided on the top of one side of the clamping airbag 17.

[0048] In a specific implementation, the pressure relief valve is pre-set with a preset pressure value. When the pressure in the clamping airbag 17 is higher than the preset pressure value, the pressure relief valve opens to discharge the excess gas in the clamping airbag 17. The gas outlet check valve can only allow the gas in the built-in gas cylinder 22 to flow into the clamping airbag 17, and the gas inlet check valve can only allow the gas in the outside atmosphere to enter the built-in gas cylinder 22.

[0049] As a further embodiment of the present invention, the component includes a sliding ring 16, both sides of the top of the sliding ring 16 are fixedly connected with connecting rods 14, the top of the connecting rod 14 is fixedly connected with a sliding plate 13, the two ends of the bottom of the beam 5 are fixedly connected with sleeves 7, the sliding ring 16 is slidably connected in the side walls of the sleeve 7, two monitoring cameras 8 are respectively fixedly sleeved in the two sleeves 7, and the top of the sleeve 7 is connected to the horizontal groove 15.

[0050] In a specific implementation, the connecting rod 14 passes through the top wall plate of the cross beam 5 , the sliding plate 13 is located above the cross beam 5 , and the sliding ring 16 is located below the cross beam 5 .

[0051] As a further implementation scheme of the present invention, both ends of the top of the beam 5 are fixedly connected with a fixed cylinder 9, the sliding plate 13 is slidably connected in the fixed cylinder 9, the connecting rod 14 passes through the top wall plate of the beam 5 and extends into the fixed cylinder 9, and the electromagnet 12 is fixedly connected to the inner top wall plate of the fixed cylinder 9, and the electromagnet 12 attracts the sliding plate 13 by magnetic force.

[0052] In a specific implementation, an interlayer is provided between the electromagnet 12 and the sliding plate 13, and the interlayer is pre-filled with compressed gas. When the magnetism of the electromagnet 12 disappears, the compressed gas will expand. During the expansion of the compressed gas, the compressed gas will push the sliding plate 13 downward, thereby making the sliding plate 13 block the outside of the surveillance camera 8, so as to achieve the protection effect on the surveillance camera 8.

[0053] As a further embodiment of the present invention, a dumping power-off switch 6 is fixedly connected to the bottom wall plate of the cross beam 5 , and the dumping power-off switch 6 is electrically connected to the two electromagnets 12 respectively.

[0054] In a specific implementation, when the support column 4 topples over, the toppling power-off switch 6 will disconnect the electrical connection with the electromagnet 12 to cut off the power to the electromagnet 12. After the power to the electromagnet 12 is cut off, the magnetism generated by the power supply to the electromagnet 12 will disappear.

[0055] Working principle of the present invention:

[0056] When the present invention is used, the base 1 is first embedded in the area where the community needs to install monitoring equipment, and then the base 1 can be reinforced by laying concrete, and then the base 1 can be reinforced by embedding the base 1 under the ground. After the installation is completed, the pre-laid lines are connected to the cable trough 18 through the wiring trough 19, and then electrically connected to the monitoring camera 8 through the horizontal groove 15 inside the crossbeam 5. In the prior art, the security network in the community is usually achieved by building a monitoring network, and the lines connecting the monitoring cameras 8 are often pre-laid underground in the community. Through the setting of the cable trough 18, the wiring trough 19 and the horizontal groove 15, the monitoring network can be effectively built to maintain the safety of the community. It should be noted that the inside of the base 1 is pre-laid with holes for wiring. The wiring of the monitoring camera 8 can be achieved by connecting the pre-buried lines to the holes and then connecting them to the wiring trough 19.

[0057] After the wiring is completed, by pressing the fan plate 3 multiple times, during the process of pressing the fan plate 3, the fan plate 3 will squeeze the piston rod 24, and then the piston rod 24 will drive the piston plate 25 to descend. During the process of the piston plate 25 descending, the space above the piston plate 25 will draw air from the outside atmosphere through the fourth air pipe 29, and then under the action of the return spring 23, the return spring 23 will push the piston plate 25 upward, thereby squeezing the air in the built-in air cylinder 22, and then allow the air to enter the fan-shaped airbag 2 through the third air pipe 28. After multiple pressings, when the fan-shaped airbag 2 expands to the point where it can no longer be replenished by pressing the fan plate 3, stop pressing the fan plate 3. At this time, the fan-shaped airbag 2 can effectively support the fan plate 3.

[0058] After installation, the fan-shaped plate 3 can also be used to provide pedestrians with a rest. When a pedestrian sits on the fan-shaped plate 3, the fan-shaped plate 3 will be lowered, and then the piston plate 25 will be driven to lower through the piston rod 24. After the piston plate 25 drops to a certain extent, it stops falling. After the pedestrian finishes resting, the piston plate 25 will rise again to achieve the purpose of replenishing the fan-shaped airbag 2. During the process of the piston plate 25 rising and falling, the return spring 23 will push the fan-shaped plate 3 upward, and after the gas in the fan-shaped airbag 2 is compressed, it will also push the fan-shaped plate 3 upward, and the return spring 23 and the fan-shaped airbag 2 jointly achieve the support work for the pedestrian.

[0059] During the process of the piston plate 25 being raised and lowered, the built-in air cylinder 22 whose bottom is connected to the first air pipe 26 and the second air pipe 27 will replenish air to the clamping air bag 17. During the process of the piston plate 25 being lowered, the piston plate 25 will squeeze the air in the space below the piston plate 25 in the built-in air cylinder 22 into the first air pipe 26 to expand the clamping air bag 17. During the process of the piston plate 25 being raised, the space below the piston plate 25 in the built-in air cylinder 22 will draw air through the second air pipe 27.

[0060] After the clamping airbag 17 is inflated, the clamping airbag 17 will effectively clamp the support column 4. On the one hand, it can seal the circular groove, and on the other hand, it can also provide auxiliary support for the support column 4, which is beneficial to maintaining the balance of the support column 4 so that the support column 4 can be in a vertical state. During the lifting and lowering of the fan-shaped plate 3, the limit block 31 will also slide in the limit groove 32. Through the setting of the limit block 31 and the limit groove 32, the support column 4 can be effectively assisted and supported. When the support column 4 tends to tip over, the tipping force of the support column 4 will be transmitted to the fan-shaped plate 3 through the slide rail 30, and then transmitted to the limit block 31 through the fan-shaped plate 3, and then transmitted to the limit groove 32 through the limit block 31, and then transmitted to the rectangular column 11 through the limit groove 32, so that the rectangular column 11 can effectively support the support column 4, and during the expansion of the fan-shaped airbag 2, the fan-shaped airbag 2 can also support the support column 4.

[0061] In windy weather, the arrangement of the clamping airbag 17 and the fan-shaped airbag 2 can effectively share the force exerted on the support column 4, which helps to avoid the support column 4 being blown down due to excessive wind. During the shaking of the support column 4, the support column 4 can be buffered to a certain extent to reduce the impact exerted on the support column 4. In addition, during windy weather, the arrangement of the limit block 31 and the rectangular column 11 can also effectively support the support column 4, which helps to avoid the support column 4 from tipping over.

[0062] Since there are often vehicles driving in the community, if the driver is not careful, the vehicle may easily collide with the support column 4. The setting of the fan-shaped airbag 2 can buffer the impact of the vehicle. When the vehicle hits the fan-shaped airbag 2, if the driver brakes in time, the contact between the vehicle and the fan-shaped airbag 2 will not cause excessive damage to either the vehicle or the support column 4, which is beneficial to ensuring the safety of the vehicle and the surveillance camera 8 installed on the top of the support column 4.

[0063] When the impact force is too great, the setting of the fan-shaped airbag 2 can also effectively reduce the degree of damage to the vehicle. When the impact force is too great, the limit block 31 or the rectangular column 11 will break, causing the support column 4 to fall over. During the falling of the support column 4, the falling power-off switch 6 will be turned on, causing the electromagnet 12 to be powered off. After the electromagnet 12 is powered off, the electromagnet 12 will stop attracting the sliding plate 13, causing the sliding plate 13 to move downward under the action of the compressed gas. The movement of the sliding plate 13 will drive the sliding ring 16 to move through the connecting rod 14, causing the sliding ring 16 to cover the outside of the surveillance camera 8, which is beneficial to avoid the surveillance camera 8 from hitting other facilities in the community due to the falling of the support column 4, thereby causing damage to the surveillance camera 8, and is beneficial to protecting the surveillance camera 8.

[0064] The electromagnet 12 is normally powered on. When powered on, it will generate magnetism. After generating magnetism, the electromagnet 12 will generate a certain magnetic field in the surrounding area. The magnetic field has the effect of driving away birds, which is helpful to prevent birds from stopping on the crossbeam 5. On the one hand, it can reduce the probability of bird droppings on the fan-shaped plate 3. On the other hand, it can also prevent pedestrians from being affected by birds when they are resting on the fan-shaped plate 3. By setting the electromagnet 12 above the monitoring camera 8, there is a certain distance between the monitoring camera 8 and the electromagnet 12, which is helpful to prevent the magnetic field of the electromagnet 12 from having an adverse effect on the monitoring camera 8.

[0065] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
