Description

Technical Field

[0001] The utility model relates to the technical field of forest fire prevention safety warning, in particular to a forest fire prevention warning device for a photovoltaic power generation area. Background Technique

[0002] In the existing photovoltaic power generation area, a large number of power equipment needs to be installed in the mountain forest. The mountain forest often catches fire due to various reasons. These devices will be quickly burned and suffer great losses when encountering a fire. Therefore, it is necessary to set up corresponding fire prevention warning devices inside the photovoltaic power station to warn and remind personnel; most forest fire prevention warning signs are composed of a vertical pole and a warning sign body, and are mostly set at prominent positions in open areas. The current forest fire prevention warning signs are also developing in the directions of publicity and guidance, detection and recording, induction alarm, etc.

[0003] For the existing forest fire prevention warning signs, with the increase in functionality, the sign face of the warning sign is set relatively large. For the warning signs located in open areas, when encountering strong wind and strong air current weather, the sign face is subjected to a large wind flow impact force, and the vertical pole is difficult to stably support the warning sign, and there is a risk of the warning sign falling down.

[0004] The existing Chinese patent with the publication number of CN213339414U discloses a multifunctional warning sign for forest fire prevention safety, including a support block. The top of the support block is movably connected with a support frame through a bolt. One side of the support frame is movably connected with a rotating rod through a rotating shaft. One side of the rotating rod is movably connected with a display board. A warning belt is arranged on the surface of the display board. The bottom of the support block is fixedly connected with a load-bearing column. A load-bearing spring is movably connected inside the load-bearing column. For this multifunctional warning sign for forest fire prevention safety, through the setting of the bolt and the support frame, the display surface of the warning sign can rotate freely, and the orientation of the display surface can be freely changed, making the display freedom of the device higher. Through the setting of the rotating shaft, the rotating rod and the display board, when the device is blown by strong wind, the display board rotates through the rotating shaft, greatly reducing the external force influence on the device itself, reducing the probability of the device falling down, and improving the working efficiency of the device.

[0005] In view of the above and the existing related technologies, the inventor believes that the following defects often exist: the display board of this device rotates under the influence of wind force, and when the display board rotates suddenly, it is easy to touch the nearby personnel and needs to be improved; therefore, a forest fire prevention warning device for a photovoltaic power generation area is proposed for the above problems. Content of the Utility Model

[0006] In order to make up for the deficiencies of the existing technology and solve the above-mentioned technical problems, the utility model proposes a forest fire prevention warning device for a photovoltaic power generation area.

[0007] The technical solution adopted by the utility model to solve its technical problems is as follows: A forest fire prevention warning device for a photovoltaic field area described in the utility model includes two columns. A warning device is rotatably connected by a shaft on the opposite sides of the two columns. The warning device includes an outer frame. A fire prevention warning display screen is rotatably connected by a shaft inside the outer frame. A loudspeaker is built in the fire prevention warning display screen. A flipping assembly is installed on the column. The flipping assembly includes a driver, four first positioning holes, and four first electric push rods. The driver is fixedly installed on the side wall of the column, and the driving end of the driver penetrates through the column and is fixedly connected to the shaft of the warning device. The four first electric push rods are respectively fixedly installed at the four corners of the warning device. The driving end of the first electric push rod is fixedly connected with a clamping block. The four first positioning holes are respectively opened on the surface of the column, and the first positioning holes are located on the moving track of the clamping block. By extending the first electric push rod, the clamping block is inserted into the inside of the first positioning hole to improve the stability of the warning device. When in use, fire prevention warning-related video information is played through the fire prevention warning display screen. The wind speed and wind direction near the device are monitored by a wind speed sensor and a wind direction sensor. When the wind speed is relatively high, when the first electric push rod contracts, the clamping block withdraws from the first positioning hole, and the warning device is driven by the driver to rotate to a horizontal state to reduce wind resistance, greatly reducing the wind force impact on the device itself and reducing the probability of the device tipping over.

[0008] Preferably, a wind speed sensor and a wind direction sensor are respectively fixedly connected to the tops of the two columns.

[0009] Preferably, the flipping assembly further includes two sliding seats. The two sliding seats are respectively slidably installed on the column. Brackets are respectively hinged on both sides of the sliding seat. The top ends of the brackets are hinged with a positioning plate. One end of the positioning plate is hinged with the column. The positioning plate is pushed to rotate by the up and down sliding of the sliding seat in cooperation with the brackets.

[0010] Preferably, a second positioning hole is opened on the surface of the positioning plate.

[0011] Preferably, the bottom of the sliding seat is fixedly connected with a second electric push rod, and the bottom end of the second electric push rod is fixedly connected with the column. When the warning device rotates to a horizontal state, the second electric push rod extends to push the sliding seat to rise, and the positioning plate is pushed to rotate and keep perpendicular to the column through the brackets. Subsequently, the first electric push rod expands and contracts so that the clamping block is inserted into the inside of the second positioning hole, thereby enhancing the stability of the warning device in the horizontal state.

[0012] Preferably, a storage box is fixedly connected to the lower side wall of the column, and a fire extinguisher is placed in the storage box. When a fire occurs, the fire extinguisher can be taken nearby to extinguish the fire, reducing the fire risk.

[0013] Preferably, a rotating assembly is installed on the outer frame and the fire warning display screen. The rotating assembly is installed in the rear area of the fire warning display screen. The rotating assembly includes two electric sliding tables, which are respectively fixedly installed on the upper and lower side walls of the outer frame. When the wind speed is relatively low, the wind direction is detected by the wind direction sensor, and the mounting frame is driven by the electric sliding table to slide in the direction of the blowing wind. Subsequently, the electric push rod three extends to push the fire warning display screen to rotate and keep consistent with the wind direction, thereby reducing wind resistance and not affecting the viewing of nearby personnel.

[0014] Preferably, a U-shaped mounting frame is fixedly connected to the sliders of the two electric sliding tables, and a plurality of sliding grooves are formed on the surface of the fire warning display screen.

[0015] Preferably, the side wall of the mounting frame is fixedly connected with an electric push rod three. The driving end of the electric push rod three is hinged with a sliding support seat, and the sliding support seat is slidably connected with the sliding groove.

[0016] The beneficial effects of the present utility model are as follows:

[0017] 1. The present utility model plays video information related to fire warning through the warning device, monitors the wind speed and wind direction near the device through the wind speed sensor and the wind direction sensor.

[0018] 2. The present utility model detects the wind direction through the wind direction sensor, drives the mounting frame to slide in the direction of the blowing wind by the electric sliding table, and then the electric push rod three extends to push the fire warning display screen to rotate and keep consistent with the wind direction, thereby reducing wind resistance and not affecting the viewing of nearby personnel. When the fire warning display screen flips or rotates, a voice prompt is given through the built-in speaker thereof to remind the nearby personnel to pay attention to the fact that the fire warning display screen is about to flip or rotate, so as to avoid accidentally hurting the nearby personnel.

[0027] Embodiment 1

[0028] Please refer to Figures 1-4As shown in the figure, a forest fire prevention warning device for a photovoltaic field area includes two columns 1. On the opposite sides of the two columns 1, a warning device 2 is rotatably connected by a shaft. The warning device 2 includes an outer frame 21. Inside the outer frame 21, a fire prevention warning display screen 22 is rotatably connected by a shaft. A flipping assembly 3 is installed on the column 1. The flipping assembly 3 includes a driver 31, four first positioning holes 32, and four first electric push rods 33. The driver 31 is fixedly installed on the side wall of the column 1, and the driving end of the driver 31 penetrates the column 1 and is fixedly connected to the shaft of the warning device 2. The four first electric push rods 33 are respectively fixedly installed at the four corners of the warning device 2. The driving end of the first electric push rod 33 is fixedly connected with a clamping block 39. The four first positioning holes 32 are respectively opened on the surface of the column 1, and the first positioning holes 32 are located on the moving track of the clamping block 39. By extending the first electric push rod 33, the clamping block 39 is inserted into the first positioning hole 32 to improve the stability of the warning device 2. When in use, fire prevention warning-related video information is played through the warning device 2. The wind speed and wind direction near the device are monitored by a wind speed sensor 4 and a wind direction sensor 5. When the wind speed is relatively high, when the first electric push rod 33 contracts, the clamping block 39 withdraws from the first positioning hole 32, and the warning device 2 is driven by the driver 31 to rotate to a horizontal state to reduce wind resistance, greatly reducing the wind force impact on the device itself and reducing the probability of the device tipping over. The magnitude of the wind speed can be flexibly divided according to the wind conditions near the photovoltaic field area.

[0029] At the tops of the two columns 1, a wind speed sensor 4 and a wind direction sensor 5 are respectively fixedly connected.

[0030] The flipping assembly 3 further includes two sliding seats 34. The two sliding seats 34 are respectively slidably installed on the column 1. On both sides of the sliding seat 34, a bracket 35 is hinged. At the top of the bracket 35, a positioning plate 36 is hinged. One end of the positioning plate 36 is hinged to the column 1. By sliding the sliding seat 34 up and down and cooperating with the bracket 35, the positioning plate 36 is pushed to rotate.

[0032] At the bottom of the sliding seat 34, a second electric push rod 38 is fixedly connected, and the bottom end of the second electric push rod 38 is fixedly connected to the column 1. When the warning device 2 rotates to a horizontal state, the second electric push rod 38 extends to push the sliding seat 34 to rise, and through the bracket 35, the positioning plate 36 is pushed to rotate and keep perpendicular to the column 1. Subsequently, the first electric push rod 33 expands and contracts to make the clamping block 39 inserted into the second positioning hole 37, thereby enhancing the stability of the warning device 2 in the horizontal state.

[0033] At the lower side wall of the column 1, a storage box 6 is fixedly connected, and a fire extinguisher is placed in the storage box 6. When a fire occurs, the fire extinguisher can be taken nearby to extinguish the fire, reducing the fire risk.

[0034] Embodiment 2

[0035] Comparing with the first comparative example, please refer to Figure 5 As shown, the present utility model provides another implementation manner. A rotating assembly 7 is installed on the outer frame 21 and the fire warning display screen 22. The rotating assembly 7 is installed in the rear area of the fire warning display screen 22. The rotating assembly 7 includes two electric sliding tables 71 up and down. The electric sliding tables 71 are respectively fixedly installed on the upper and lower side walls of the outer frame 21. When the wind speed is relatively low, the wind direction is detected by the wind direction sensor 5, and the mounting frame 72 is driven by the electric sliding table 71 to slide in the direction of the incoming wind. Subsequently, the electric push rod three 73 extends to push the fire warning display screen 22 to rotate and keep in line with the wind direction, thereby reducing wind resistance and not affecting the viewing of nearby personnel. When the fire warning display screen 22 flips or rotates, voice prompts are given through the built-in speaker thereof to remind the nearby personnel that the fire warning display screen 22 is about to flip or rotate, so as to avoid accidentally hurting the nearby personnel.

[0036] A U-shaped mounting frame 72 is fixedly connected to the sliders of the two electric sliding tables 71, and a plurality of sliding grooves 8 are formed on the surface of the fire warning display screen 22.

[0037] A side wall of the mounting frame 72 is fixedly connected with an electric push rod three 73. The driving end of the electric push rod three 73 is hinged with a sliding support seat 74, and the sliding support seat 74 is slidably connected with the sliding groove 8.

[0038] For those skilled in the art, all the electrical components in this case are connected to their adapted power supplies through wires, and appropriate controllers should be selected according to the actual situation and electrically connected to the fire warning display screen 22, the wind speed sensor 4, the wind direction sensor 5, the electric sliding table 71, the driver 31, the electric push rod one 33, the electric push rod two 38 and the electric push rod three 73 to meet the control requirements. For the specific connection and control sequence, reference should be made to the sequence of the work of each electrical component in the following working principle to complete the electrical connection. The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, and will not explain the electrical control.

[0039] Working principle: The device is electrically connected to the nearby photovoltaic field area through wires to supply power to the device. The electric push rod one 33 extends to make the clamping block 39 insert into the positioning hole one 32 to improve the stability of the warning device 2. When in use, the warning device 2 plays video information related to fire warning. The wind speed and wind direction near the device are monitored by the wind speed sensor 4 and the wind direction sensor 5. When the wind speed is relatively high, when the electric push rod one 33 contracts, the clamping block 39 withdraws from the positioning hole one 32, and the warning device 2 is driven by the driver 31 to rotate to a horizontal state to reduce wind resistance, greatly reducing the wind force on the device itself and reducing the probability of the device tipping over.

[0040] When the warning device 2 rotates to the horizontal state, the second electric push rod 38 extends to push the sliding seat 34 to rise, and through the support 35, it pushes the positioning plate 36 to rotate and be perpendicular to the column 1. Subsequently, the first electric push rod 33 expands and contracts to make the clamping block 39 insert into the interior of the second positioning hole 37, thereby enhancing the stability of the warning device 2 in the horizontal state.

[0041] When the wind speed is relatively small, the wind direction is detected by the wind direction sensor 5, and the mounting frame 72 is driven by the electric sliding table 71 to slide in the direction of the incoming wind. Subsequently, the third electric push rod 73 extends to push the fire warning display screen 22 to rotate and be consistent with the wind direction, thereby reducing wind resistance and not affecting the viewing of nearby personnel. When the fire warning display screen 22 flips or rotates, voice prompts are given through the built-in speaker thereof to remind the nearby personnel that the fire warning display screen 22 is about to flip or rotate, so as to avoid accidentally hurting the nearby personnel.
