Description

Technical Field

[0001] The utility model belongs to the technical field of safety warnings, and in particular relates to a safety warning device for a wind farm. Background Art

[0002] A wind farm refers to an electric field that uses wind power to generate electricity. In today's resource-scarce world, utilizing renewable wind resources not only reduces resource consumption, but also reduces pollution to the outside world during the power generation process, which can be said to kill two birds with one stone. In the process of power generation at a wind farm, the potential safety hazards are still very noteworthy. Warning signs are installed around the wind farm to warn nearby pedestrians.

DETAILED DESCRIPTION

[0051] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0052] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0053] like Figure 1 , Figure 2 FIG. 1 is a schematic diagram of a safety warning device for a wind farm provided by an embodiment of the utility model, comprising:

[0054] Warning sign 1;

[0055] A bracket 2, wherein the bracket 2 is fixed to the bottom of the warning sign 1;

[0056] An LED warning light bar 3, wherein the LED warning light bar 3 is installed on the front side of the warning sign 1;

[0057] A rotating support frame 4, wherein the rotating support frame 4 is installed on the top of the LED warning light strip 3;

[0058] A water collecting shell 5, wherein the water collecting shell 5 is rotatably disposed on the top of the rotating support frame 4;

[0059] A control box 6, which is fixed to the rear side of the warning sign 1, and contains a battery pack 21 and a controller 22;

[0060] A mounting plate 7, wherein the mounting plate 7 is movably disposed in the control box 6 and is connected to an adjustment module for adjusting its position;

[0061] A normally closed control switch 8, wherein the normally closed control switch 8 is mounted on a mounting plate 7;

[0062] The end of the water collecting shell 5 away from the warning sign 1 is supported by an elastic supporting mechanism 100;

[0063] The normally closed control switch 8 is used to detect whether the elastic supporting mechanism 100 is contracted.

[0064] In the embodiment of the utility model, when encountering rainy weather, dense rainwater will gather in the water collecting shell 5. As the rainwater gathers too much, since the water collecting shell 5 is set with its long arm located on the back side of the warning sign 1, under the gravity of the rainwater, it will flip toward the back side of the warning sign 1 along the rotating support frame 4 as a fulcrum, and the water collecting shell 5 drives the elastic support mechanism 100 to move, and the elastic support mechanism 100 contracts, thereby triggering the normally closed control switch 8 on the mounting plate 7, so that the normally closed control switch 8 is in an open and closed state, and the normally closed control switch 8 transmits its own state to the controller 22. The controller 22 detects that the normally closed control switch 8 is in an open and closed state, thereby controlling the battery pack 21 to supply power to the LED warning light bar 3 on the surface of the warning sign 1, and the LED warning light bar 3 is in a flashing and bright state, thereby solving the problem of reducing the field of vision of pedestrians. Pedestrians will also hold umbrellas to block the rain, and the umbrellas will further reduce the line of sight of pedestrians, causing pedestrians to easily fail to notice the warning signs, resulting in the problem of reduced warning effect of the warning signs.

[0065] like Figure 2 As shown, as a preferred embodiment of the utility model, the elastic support mechanism 100 includes:

[0066] An elastic support assembly, wherein the elastic support assembly is fixed to a side surface of the control box 6;

[0067] A connecting rod assembly, wherein the connecting rod assembly is rotatably connected to an end of the water collecting shell 5 away from the warning sign 1 and the elastic support assembly;

[0068] The extrusion rod 15 is fixed to the side surface of one end of the elastic support assembly close to the connecting rod assembly and is slidably connected to the control box 6.

[0069] In the embodiment of the utility model, when in use, since the water collecting shell 5 is set, its long arm is located on the back side of the warning sign 1, so that under the gravity of rainwater, it flips toward the back side of the warning sign 1 along the rotating support frame 4 as a fulcrum, and the water collecting shell 5 drives the connecting rod assembly to move, and the connecting rod assembly drives the elastic support assembly to overcome the elastic force and shrink, and the elastic support assembly drives the extrusion rod 15 to move, and the extrusion rod 15 slides along the control box 6 toward the normally closed control switch 8. When the extrusion rod 15 contacts the normally closed control switch 8, it squeezes it, thereby switching it from the normally closed state to the open state, and the normally closed control switch 8 transmits its own state to the controller 22, and the controller 22 detects that the normally closed control switch 8 is in the open state, thereby controlling the battery pack 21 to supply power to the LED warning light bar 3 on the surface of the warning sign 1, and the LED warning light bar 3 is in a flashing and bright state, thereby improving the warning effect and solving the problem of poor vision in the rainy environment.

[0070] In one case of this embodiment, the elastic support assembly includes:

[0071] Support sleeve 16;

[0072] A sliding limit block 17, wherein the sliding limit block 17 is slidably matched with the support sleeve 16;

[0073] A first elastic member 18, wherein the first elastic member 18 is fixedly connected to the bottom of the sliding limit block 17 and the inner wall of the support sleeve 16 respectively;

[0074] The third connecting rod 14 passes through the supporting sleeve 16 and is fixed on the sliding limit block 17 .

[0075] In this embodiment, the third connecting rod 14 is limited by the sliding limit block 17 so that the third connecting rod 14 cannot be separated from the support sleeve 16. The elastic force of the first elastic member 18 supports the sliding limit block 17 and the third connecting rod 14, and then supports the connecting rod assembly and the water collecting shell 5.

[0076] In one aspect of this embodiment, the connecting rod assembly includes:

[0077] A first connecting rod 10, wherein the first connecting rod 10 is connected to the water collecting shell 5;

[0078] A first articulated frame 11, wherein the first articulated frame 11 is fixedly connected to the first connecting rod 10;

[0079] A second connecting rod 12, the second connecting rod 12 is obliquely distributed and one end of the second connecting rod 12 is rotatably connected to the first articulated frame 11;

[0080] The second articulated frame 13 is rotatably connected to the second connecting rod 12 , and the second articulated frame 13 is connected to the third connecting rod 14 .

[0081] In this embodiment, when in use, the water collecting shell 5 drives the first connecting rod 10 to move, the first connecting rod 10 drives the first articulated frame 11, the second connecting rod 12, and the second articulated frame 13 to move, and the second articulated frame 13 thereby drives the elastic support assembly to contract.

[0082] Furthermore, the second articulated frame 13 is fixedly connected with an insertion rod 19 which is nested in the third connecting rod 14, and the insertion rod 19 is used to facilitate the disassembly of the assembly.

[0083] Furthermore, the first connecting rod 10 is slidably connected to the water collecting shell 5 and fixedly connected with a baffle 20 located in the water collecting shell 5, the outer diameter of the baffle 20 is larger than the outer diameter of the first connecting rod 10, and there is damping between the first connecting rod 10 and the water collecting shell 5. When the water collecting shell 5 is flipped over, due to the damping between the water collecting shell 5 and the first connecting rod 10, the resistance caused by the damping is greater than the elastic force of the first elastic member 18, so that the water collecting shell 5 drives the first connecting rod 10 to move, and the position of the first connecting rod 10 relative to the water collecting shell 5 does not change. When the elastic force of the first elastic member 18 is greater than the resistance between the first connecting rod 10 and the water collecting shell 5, the first connecting rod 10 drives the first articulated frame 11 and the second connecting rod 12 to move and slide along the water collecting shell 5. At this time, the baffle 20 is away from the bottom of the water collecting shell 5, and rainwater flows out of the water collecting shell 5 from the gap between the first connecting rod 10 and the water collecting shell 5.

[0084] like Figure 2 , Figure 3 As shown, as another preferred embodiment of the present utility model, the adjustment module includes:

[0085] A driving sleeve 24, wherein the driving sleeve 24 is rotatably disposed in the control box 6 and is connected to a driving mechanism 200 for driving the driving sleeve 24 to rotate;

[0086] The eccentric wheel 23 is mounted on the driving sleeve 24 , and the eccentric wheel 23 abuts against the bottom of the mounting plate 7 .

[0087] In the embodiment of the utility model, when in use, the driving mechanism 200 drives the driving sleeve 24 to rotate, and the driving sleeve 24 drives the eccentric wheel 23 to rotate, so that the eccentric wheel 23 changes the support height. At this time, the mounting plate 7 drives the normally closed control switch 8 to move under the action of gravity.

[0088] like Figure 3 As shown, as another preferred embodiment of the utility model, the driving mechanism 200 includes:

[0089] A driving rod 25, wherein the driving rod 25 is slidably connected to the driving sleeve 24;

[0090] A rotating handle 26, wherein the rotating handle 26 is fixed to one end of the driving rod 25 outside the control box 6;

[0091] An elastic clamping unit, which is used to fix the driving rod 25 , the driving sleeve 24 and the control box 6 .

[0092] In the embodiment of the utility model, when in use, the control box 6, the drive sleeve 24, and the drive rod 25 are fixed by the elastic snap-in unit. When they need to be released, it is only necessary to pull the turning handle 26 so that the turning handle 26 drives the drive rod 25 to slide along the drive sleeve 24. At this time, the movement of the drive rod 25 causes the elastic snap-in unit to contract and disengage.

[0093] In one case of this embodiment, the elastic clamping unit includes:

[0094] A limiting slide groove 27, wherein the limiting slide groove 27 is disposed in the driving rod 25;

[0095] A clamping slider 28, wherein the clamping slider 28 is slidably matched with the limiting slide groove 27, and one end of the clamping slider 28 is arc-shaped and partially penetrates the driving sleeve 24 and is nested in the control box 6;

[0096] The second elastic member 9 has two ends fixedly connected to the bottom of the clamping slider 28 and the inner wall of the limiting sliding groove 27 respectively.

[0097] In this embodiment, when in use, the elastic force of the second elastic member 9 drives the clamping slider 28 to slide along the limiting slide groove 27 and penetrate the drive sleeve 24 to be embedded in the control box 6, thereby fixing the drive sleeve 24 so that it cannot rotate.

[0098] The above embodiment of the utility model provides a safety warning device for a wind farm, by setting a warning sign 1, an LED warning light bar 3, a rotating support frame 4, a water collecting shell 5, a control box 6, a mounting plate 7, a normally closed control switch 8, a battery pack 21, a controller 22 and an elastic support mechanism 100, when encountering rainy weather, dense rainwater will gather in the water collecting shell 5, as too much rainwater gathers, because when the water collecting shell 5 is set, its long arm is located on the back side of the warning sign 1, so that under the gravity of the rainwater, it turns toward the back side of the warning sign 1 along the rotating support frame 4 as a fulcrum, and the water collecting shell 5 drives the elastic support mechanism 100 to move, The elastic support mechanism 100 contracts, thereby triggering the normally closed control switch 8 on the mounting plate 7, so that the normally closed control switch 8 is in an open or closed state. The normally closed control switch 8 transmits its own state to the controller 22. The controller 22 detects that the normally closed control switch 8 is in an open or closed state, thereby controlling the battery pack 21 to supply power to the LED warning light bar 3 on the surface of the warning sign 1. The LED warning light bar 3 is in a flashing state, thereby solving the problem of reducing the field of vision of pedestrians. Pedestrians will also hold umbrellas to block rain, and umbrellas will further reduce the line of sight of pedestrians, causing pedestrians to easily fail to notice the warning signs, resulting in reduced warning effect of the warning signs.
