Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0038] Example 1: As Figure 1 , 4 As shown in Figures 5 and 9, the present invention provides a warning light-type nighttime power construction warning sign, comprising a base 1, a support assembly 2, a sign 3, a telescopic brace 4, and a photovoltaic panel assembly 5; a battery is installed in the space formed inside the base 1; the support assembly 2 is installed on the top of the base 1, and a rectangular plate-shaped sign 3 is fixed on the top of the support assembly 2; the photovoltaic panel assembly 5 is installed on the back of the sign 3, and a warning light 33 is installed on the top of the sign 3; the photovoltaic panel assembly 5 is connected to the battery through a solar charge controller, and the battery is connected to the sign 3 and the warning light 33 through an inverter to provide power to the sign 3 and the warning light 33.

[0039] like Figure 5 The base 1 includes a housing 10 with an open bottom side. The bottom end of the housing 10 is fixed with a base plate 11 by bolts, which facilitates opening and maintenance of internal components. A support plate 13 is installed on the upper surface of the base plate 11 by a column 12. The inverter and solar charging controller are installed on the upper surface of the support plate 13, while the battery is installed on the upper surface of the base plate 11. The layout is reasonable and conducive to heat dissipation and maintenance.

[0040] Specifically, to facilitate adjusting the orientation of the photovoltaic panel assembly 5 after the device is installed at the corresponding ground position, the signboard 3 includes a frame 30. A partition 31 is provided inside the frame 30, dividing the frame into two areas. The signboard body 32 is installed in the area on one side of the partition 31. The photovoltaic panel assembly 5 is rotatably installed on the top of the frame 30 between the two inner walls via a pivot. Telescopic braces 4 are rotatably installed on both ends of the frame 30 via pivots. The ends of the telescopic braces 4 can be connected to the side ends of the frame 30 or the photovoltaic panel assembly 5 to support and lock the angle of the photovoltaic panel. This design allows the photovoltaic panel assembly 5 to be adjusted according to the angle of solar radiation.

[0041] Specifically, the telescopic brace 4 includes an outer sleeve 40 rotatably mounted on the frame 30 via a pivot shaft. A pin is threaded onto the side wall of the outer sleeve 40. A movable sleeve rod 41 is movably inserted into the outer sleeve 40. Multiple first pin holes 42, which mate with the pins, are provided along the length of the movable sleeve rod 41 for coarse length adjustment to support the photovoltaic panel assembly 5 at different tilt angles. The photovoltaic panel assembly 5 includes a photovoltaic panel mounting frame 50, within which a photovoltaic panel body 51 is mounted. Gap channels 52 are formed between both sides of the photovoltaic panel body 51 and the inner wall of the photovoltaic panel mounting frame 50. These gap channels 52 facilitate rainwater drainage during rainfall, preventing water or debris accumulation and improving the working efficiency and service life of the photovoltaic panel.

[0042] Example 2, based on Example 1, to facilitate fixing the unfolded and retracted photovoltaic panel assembly 5, as follows: Figure 2 A pin assembly A6 is installed at the end of the photovoltaic panel assembly 5, and a pin assembly B8 is installed at the top of the frame 30. The end of the movable sleeve 41 is provided with a second pin hole for cooperating with the pin assembly A6 or the pin assembly B8 to achieve quick connection and locking.

[0043] like Figure 10-12 Pin assembly B8 and pin assembly A6 have the same structure; taking pin assembly A6 as an example, its detailed structure is as follows: Figure 7 and Figure 8 As shown, it includes a tube shell 60; a rectangular hole A602 is provided on one side wall of the middle part of the tube shell 60, and pins 61 are slidably provided in the tube shell 60 at both ends of the rectangular hole A602; the end of the pin 61 is connected to a gripping rod 62 that passes through the rectangular hole A602, which facilitates the operator's pinching operation. A guide groove 601 is formed on the inner wall of the tube shell 60 along its length. A guide strip 610 that cooperates with the guide groove 601 is provided on one side of the pin 61 to ensure that the pin can only slide in a straight line. The pin 61 is used to pass through the second pin hole at the end of the movable sleeve 41 of the telescopic brace 4. In order to make the connection more secure, a protrusion 66 that can pass through the second pin hole is provided on the end face of the pin 61. A cavity 613 is provided in the protrusion 66, and the two opposite outer walls are connected to the movable blocks 67 by an elastic structure. When the two movable blocks 67 are controlled by force to overcome the elasticity of the elastic structure and approach the protrusion 66, and then the protrusion 66 is controlled to pass through the second pin hole, the movable blocks 67 pop out under the rebound of the elastic structure and are stuck outside the second pin hole to prevent the pin 61 from accidentally falling out.

[0044] To facilitate quick unlocking of the control pin 61, a rectangular cavity 611 is provided inside the pin 61 along its axial direction, and the cavity 611 is connected to the chamber 613 inside the protrusion 66; a rectangular hole B612 is provided on one side of the pin 61; a slider 641 is slidably arranged on the inner wall of the cavity 611 along its length; the slider 641 is connected to a movable gripping rod 64 through a connecting block passing through the rectangular hole B612; an elastic telescopic sleeve 63 is connected between the movable gripping rod 64 and the gripping rod 62 for resetting; the slider 641 is positioned on the side near the protrusion 66. A pair of side plates 642 are connected by a connecting rod 643; a traction rope 65 is connected between the connecting rod 643 and the bottom side of the slot inside the movable block 67; when the movable gripping rod 64 and the gripping rod 62 are pinched, the movable block 67 will be pulled to the side closer to the protrusion 66 through the slider 641 and the traction rope 65, and then the pin 61 can be pulled out from the second pin hole to achieve quick unlocking; when in use, the gripping rod 62 drives the pin 61 to move inside the tube shell 60, and the movable gripping rod 64 drives the slider 641 to move inside the cavity 611.

[0045] The bottom of frame 30 has two opposite side walls with insertion holes 34 for inserting the end of pin 61. The cross-section of insertion hole 34 is convex.

[0046] In Example 3, based on Example 1, to facilitate control of the overall movement of the device and to ensure its stable placement after it has been moved to the appropriate position, rollers 19 are installed on the bottom side of the base 1; as shown... Figure 7-8A counterweight sleeve 7 is also provided, which is movably fitted onto the outer periphery of the base 1. The counterweight sleeve 7 includes a counterweight sleeve body 71 made of cast iron. By distributing the weight, it lowers during use to reduce the overall center of gravity, thereby increasing the overall stability after placement. Rectangular heat dissipation holes 72 are provided on the periphery of the counterweight sleeve body 71 to help dissipate heat from the internal components of the base. U-shaped handles 70 are provided on both sides of the top of the counterweight sleeve body 71 for easy pushing and pulling. A rectangular slot 74 is provided on the top of the counterweight sleeve body 71, and an opening D73 communicating with it is provided on one side of the counterweight sleeve body 71. Correspondingly, a protruding post 18 is provided on the outer wall of the base 1, and a movable sleeve 181 is movably connected to the protruding post 18. The diameter of the protruding post 18 is smaller than the width of the rectangular slot 74, and the diameter of the opening D73 is larger than that of the movable sleeve 181. Operate the U-shaped handrail 70 to control the counterweight sleeve 7 to move upwards. After the protrusion 18 passes through the rectangular slot 74, the diameter of the movable sleeve 181 is larger than the width of the rectangular slot 74. After sliding into the opening D73, control the movable sleeve 181 to move towards the side closer to the base 1 on the protrusion 18 until the movable sleeve 181 slides into the opening D73. Remove the external force controlling the U-shaped handrail 70. At this time, the counterweight sleeve 7 moves downwards under its own weight. The movable sleeve 181 abuts against the joint of the opening D73 and the rectangular slot 74, completing the support of the counterweight sleeve 7. Conversely, when it is necessary to control the counterweight sleeve 7 to descend and contact the ground, first operate the U-shaped handrail 70 to control the counterweight sleeve 7 to move upwards, pull out the movable sleeve 181, and operate the U-shaped handrail 70 to control the counterweight sleeve 7 to move downwards slowly.

[0047] As an alternative to the locking method of Activity Set 181, such as Figure 2 and 3 As shown, the bottom of the protruding post 18 is provided with an arc surface, and the locking blocks 76 can be set on the opposite side walls of the rectangular slot 74; the side wall of the rectangular slot 74 is provided with a mounting groove 75 for mounting the locking blocks 76, and a spring B is connected between the bottom side of the locking blocks 76 and the mounting groove 75; the upper surface of the end of the locking block 76 is provided with a guide slope 761, and the guide slope 761 on the two locking blocks 76 is V-shaped; when the U-shaped handle 70 controls the counterweight sleeve 7 to move upward along the outer wall of the base 1, the protruding post 18 presses the guide slope 761. 61. The locking block 76 retracts, and after the protrusion 18 passes through the rectangular slot 74 and slides into the opening D73, the locking block 76 pops out under the action of the spring B, releasing the external force controlling the U-shaped handrail 70. At this time, the counterweight sleeve 7 moves downward under its own weight, and the bottom of the locking block 76 is supported on the top of the protrusion 18. One side of the locking block 76 is connected to the operating rod 77, and one side of the mounting groove 75 is provided with a clearance groove 751 to avoid the operating rod 77. The locking block 76 can be retracted by moving the operating rod 77, which makes it easy to disassemble the counterweight sleeve 7.

[0048] In practical use, operators can move the sign to the power construction area using the U-shaped handrail 70 and rollers 19. The counterweight 7 can be installed or removed as needed to adapt to different ground conditions. By adjusting the height of the support assembly 2 and the tilt angle of the photovoltaic panel assembly 5, the sign body 32 can be positioned in the optimal visibility position, while simultaneously ensuring the photovoltaic panel body 51 faces the sunlight. Angle adjustment is achieved through the cooperation of the telescopic brace 4 and the pin assembly, making adjustment simple and locking reliable. During the day, the photovoltaic panel converts solar energy into electrical energy stored in the battery. At night, the battery powers the illuminated sign body 32 and the flashing warning light 33, providing an effective warning effect.
