[0034] Figure 1 is an isometric schematic view of the protection device provided by the present utility model from one perspective; Figure 2 is an isometric schematic view of the protection device provided by the present utility model from another perspective.

[0035] Refer to Figure 1 and Figure 2, an embodiment of the present utility model provides a protection device, which includes a support assembly 100, a plurality of baffle assemblies 200, a drive assembly 300 and a control assembly 400. The plurality of baffle assemblies 200 are arranged on the support assembly 100 at intervals along the length direction of the support assembly 100. Each baffle assembly 200 is rotatably engaged with the support assembly 100 respectively. The baffle assembly 200 includes two states - a protection state and a ventilation state.

[0036] In the protection state, each baffle assembly 200 is connected end to end, so as to form a protection surface. In the ventilation state, any two adjacent baffle assemblies 200 can be separated at intervals by rotation. In this way, the gap between any two adjacent baffle assemblies 200 can allow air flow to pass through, and the wind resistance can be weakened in strong wind weather.

[0037] The drive assembly 300 includes a wind power generation component 310, a motor 320 and a transmission component 330. The wind power generation component 310 is electrically connected to the motor 320. The motor 320 is connected to one of the baffle assemblies 200, and this baffle assembly 200 can rotate synchronously with the motor 320. The transmission component 330 is respectively connected to each baffle assembly 200, and the transmission component 330 is used to make the plurality of baffle assemblies 200 rotate synchronously.

[0038] It can be understood that when the baffle assembly 200 connected to the motor 320 starts to rotate, the transmission component 330 will transmit power to other baffle assemblies 200, so that the plurality of baffle assemblies 200 can rotate synchronously, thereby realizing the conversion between the aforementioned protection state and ventilation state.

[0039] The control assembly 400 includes a wind speed sensor 410 and a controller 420. Any two of the wind speed sensor 410, the controller 420 and the wind power generation component 310 are electrically connected to each other. In other words, the wind speed sensor 410 is electrically connected to the controller 420 and the wind power generation component 310 respectively, and the controller 420 and the wind power generation component 310 are also electrically connected to each other.

[0040] In addition, the controller 420 is also electrically connected to the motor 320. The wind power generation component 310 can supply power to the motor 320, the wind speed sensor 410 and the controller 420. The controller 420 is used to obtain the actual wind speed in the environment through the wind speed sensor 410. Based on the actual wind speed, the controller 420 is used to control the motor 320 to drive the baffle assembly 200 to switch between the protection state and the ventilation state.

[0041] Specifically, a preset threshold is set in the controller 420. When the actual wind speed reaches the preset threshold, the controller 420 controls the motor 320 through the built-in control command to drive the baffle assembly 200 to rotate to the ventilation state; when the actual wind speed is less than the preset threshold, the controller 420 controls the motor 320 through the built-in control command to drive the baffle assembly 200 to rotate to the protection state.

[0042] It should be noted that the preset threshold can be adaptively set according to the actual situation. For example, according to factors such as the on-site wind speed and the stability of the protection device. Specifically, this embodiment does not make specific limitations on this.

[0043] Refer to Figure 1 and Figure 2 It can be understood that for the protection device provided by the embodiment of the present utility model, by setting the transmission component 330 to drive the multiple baffle assemblies 200 to rotate synchronously, this design ensures that the multiple baffle assemblies 200 can be coordinated to switch between the protection state and the ventilation state; in addition, through the wind power generation component 310 to drive the motor 320 to drive the baffle assembly 200 to switch between the protection state and the ventilation state, it converts wind energy into kinetic energy and transmits it to the baffle assembly 200, and the latter transmits the power to other baffle assemblies 200 through mechanical connection, then the conversion between wind energy and mechanical energy can be realized. This conversion has two advantages. On the one hand, wind energy can reduce the energy consumption of the protection device. On the other hand, the conversion of the baffle assembly 200 from the protection state to the ventilation state is to avoid the overturning problem of the protection device in strong wind weather, and the wind is the source of the overturning problem. By setting like this in this embodiment, the source of the overturning problem can be converted into the power source to solve this problem, which can play the role of turning the enemy into a friend. Further, by setting the wind speed sensor 410 and the controller 420, and controlling the motor 320 based on the actual wind speed, in this way, manual intervention in the state switching process of the baffle assembly 200 can be eliminated, and the automation of the protection device can be improved.

[0044] Compared with the prior art, for the protection device provided by the embodiment of the present utility model, through the wind power generation component 310 and the motor 320 to drive the multiple baffle assemblies 200 to rotate between the protection state and the ventilation state, and through the controller 420 and the wind speed sensor 410 to control the motor 320 based on the actual wind speed. By setting like this, without human intervention, the protection device can automatically rotate to the ventilation state in windy weather to reduce wind resistance, which is beneficial to the automation of the protection device; in addition, the setting of the controller 420 and the wind speed sensor 410 can enable the protection device to timely switch to the ventilation state in strong wind weather, solving the problem that the existing protection device cannot be opened in time and is inconvenient to use.

[0045] Continue to refer to Figure 1 and Figure 2, in an alternative embodiment of the present utility model, the baffle assembly 200 includes a rotating shaft 210 and a baffle 220. The baffle 220 is disposed on at least one side of the rotating shaft 210. In other words, the baffle 220 can be disposed on one side of the rotating shaft 210, or can be respectively disposed on both sides of the rotating shaft 210. The baffle 220 is adapted to rotate synchronously with the rotating shaft 210. In the protection state, the baffles 220 of each baffle assembly 200 are connected end to end. In the ventilation state, the baffles 220 of any two adjacent baffle assemblies 200 are spaced apart from each other.

[0046] Among them, the rotating shaft 210 is disposed at intervals along the length direction of the support assembly 100 and is rotationally engaged with the support assembly 100. The transmission member 330 is disposed on the same side of a plurality of rotating shafts 210 and is respectively rotationally engaged with each rotating shaft 210. The motor 320 is connected to one of the plurality of rotating shafts 210.

[0047] Specifically, when the motor 320 drives the rotating shaft 210 connected thereto to rotate, since a plurality of rotating shafts 210 are all connected to the transmission member 330, the transmission member 330 will transfer the kinetic energy to other rotating shafts 210, thereby causing all the rotating shafts 210 to rotate synchronously. When the rotating shaft 210 rotates, the baffle 220 disposed on the rotating shaft 210 rotates accordingly, and the baffles 220 of two adjacent baffle assemblies 200 can be connected or separated. Also, due to the synchronous rotation of a plurality of baffle assemblies 200, the baffle assembly 200 can be switched between the protection state and the ventilation state.

[0048] Refer to Figure 1 and Figure 2 , it can be understood that in the baffle assembly 200 provided by the embodiment of the present utility model, by providing the independent rotating shaft 210 and the baffle 220, on the one hand, it is convenient for the manufacturing, transportation and storage of the baffle assembly 200, and on the other hand, it is convenient for maintenance and replacement.

[0049] Continue to refer to Figure 1 and Figure 2 , in an alternative embodiment of the present utility model, the transmission member 330 includes a transmission rod 331 and a transmission part 332. The transmission rod 331 is disposed on the same side of the rotating shaft 210. The number of the transmission parts 332 corresponds to the number of the rotating shafts 210. One end of the transmission part 332 is rotationally connected to the rotating shaft 210, and the other end is rotationally connected to the corresponding rotating shaft 210.

[0050] It can be understood that the transmission rod 331 and the transmission part 332 are a connecting rod structure. The connecting rod structure transfers kinetic energy more directly, has less power loss, and the transmission rod 331 and the transmission part 332 are easy to replace, which can reduce the difficulty of maintenance; in addition, the connecting rod structure has strong stability and can ensure the stability of the state conversion of the baffle assembly 200.

[0051] In an alternative embodiment of the present utility model, the protection device further includes a warning component, which is electrically connected to the controller 420. When the actual wind speed reaches a preset threshold, the controller 420 controls the warning component to emit a warning message. It can be understood that by setting the warning component, the staff around the protection device can timely obtain the working state of the protection device, thereby realizing the danger of the surrounding environment. In addition, in an alternative embodiment of the present utility model, the warning component can also be used as a night reminder device for night warning.

[0052] In an alternative embodiment of the present utility model, the warning component includes at least one of a warning light and a buzzer alarm. It can be understood that the warning light can emit warning lights, and the staff can obtain the warning information through a significant visual effect; the buzzer alarm can emit warning sounds, and the staff can obtain the warning information through a significant auditory effect. Specifically, it can be adaptively selected according to the actual situation.

[0053] Continue to refer to Figure 1 and Figure 2 In an alternative embodiment of the present utility model, the wind power generation component 310 includes a wind turbine 311 and a generator 312. The wind turbine 311 is arranged on the support component 100 and is rotationally matched with the support component 100. The generator 312 is arranged at one end of the wind turbine 311 and is electrically connected to the motor 320, the wind speed sensor 410, and the controller 420 respectively. The generator 312 is adapted to rotate with the wind turbine 311. The aforementioned wind speed sensor 410 can also be arranged at the other end of the wind turbine 311 and rotate synchronously with the wind turbine 311.

[0054] Specifically, the wind turbine 311 includes a central shaft. A plurality of blades are fixedly connected to the surface of the central shaft in a radial manner. The two ends of the central shaft are respectively fixedly connected to the generator 312 and the power input end of the wind speed sensor 410. Through the plurality of blades, the central shaft can be driven to rotate by the wind force, and then the wind speed sensor 410 can be driven to rotate to collect the actual wind speed.

[0055] Continue to refer to Figure 1 and Figure 2 In an alternative embodiment of the present utility model, the drive component 300 further includes a storage battery 340. The storage battery 340 is electrically connected to the wind power generation component 310, the motor 320, the wind speed sensor 410, and the controller 420 respectively. The storage battery 340 has a charging interface. The excess power generated by the wind power generation component 310 can be stored in the storage battery 340. When the wind power generation component 310 is damaged, the storage battery 340 can be used as a backup energy source to provide electrical energy for components such as the wind power generation component 310, the motor 320, the wind speed sensor 410, and the controller 420, maintaining the normal operation of the protection device, thereby improving the stability of the protection device.

[0056] Continue to refer to Figure 1 and Figure 2 In an alternative embodiment of the present utility model, the support assembly 100 includes a base 110 and a support frame 120. The support frame 120 includes an upper bottom plate 121, a lower bottom plate 122, a first side plate 123 and a second side plate 124. The upper bottom plate 121 and the lower bottom plate 122 are arranged oppositely, and the first side plate 123 and the second side plate 124 are relatively arranged between the upper bottom plate 121 and the lower bottom plate 122; A plurality of baffle assemblies 200 are spaced between the first side plate 123 and the second side plate 124, and one end of the baffle assembly 200 is rotatably engaged with the upper bottom plate 121, and the other end is rotatably engaged with the lower bottom plate 122.

[0057] The baffle assembly 200 is parallel to the first side plate 123 and the second side plate 124, and the height of the baffle assembly 200 is adapted to the height between the upper bottom plate 121 and the lower bottom plate 122. In this way, when the baffle assembly 200 rotates to the protection state, it can cooperate with the upper bottom plate 121, the lower bottom plate 122, the first side plate 123 and the second side plate 124 to form a protection surface. The "protection surface" refers to a plane formed by the head-to-tail connection of a plurality of baffle assemblies 200, and this plane can play a protective role and can prevent people from approaching the dangerous area.

[0058] Continue to refer to Figure 1 and Figure 2 In an alternative embodiment of the present utility model, the support frame 120 further includes a first support member 125 and a second support member 126. The first support member 125 and the second support member 126 are relatively spaced on the side of the upper bottom plate 121 away from the lower bottom plate 122, and the wind power generation component 310 and the wind speed sensor 410 are arranged between the first support member 125 and the second support member 126. It can be understood that such a setting can make the overall structure of the protection device more compact and have better integrity.

[0059] Continue to refer to Figure 1 and Figure 2 In an alternative embodiment of the present utility model, the base 110 includes a first support leg 111, a second support leg 112 and a reinforcing rod 113. The first support leg 111 is arranged below the first side plate 123, the second support leg 112 is arranged below the second side plate 124, and the reinforcing rod 113 is arranged between the first support leg 111 and the second support leg 112. It can be understood that by providing the reinforcing rod 113, the connection between the first support leg 111 and the second support leg 112 can be better, which is beneficial to the stress transfer inside the base 110 and can make the load-bearing capacity of the base 110 stronger.

[0060] In summary, the protection device provided by the present utility model can be used in bridge construction. Through the wind wheel 311, wind speed and wind force can be converted into rotational force, thereby driving the wind speed sensor 410 and the generator 312. The actual wind speed is detected by the wind speed sensor 410. After the actual wind speed reaches the preset threshold of the controller 420, the motor 320 is driven to drive a plurality of rotating shafts 210 to rotate, and then drive the baffle 220 to open, so that the baffle assembly 200 can be automatically opened when the wind force is too high, realizing automation and timely opening.

[0061] It should be noted that the technical solutions in the various embodiments of the present utility model can be combined with each other, but the basis for the combination is that those of ordinary skill in the art can implement it; when the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist, that is, it does not belong to the protection scope of the present utility model either.
