[0024] like Figure 1 and Figure 2 As shown, the embodiment of the present application provides a safety reminder device for providing safety reminders, attracting the attention of passers-by, and avoiding the occurrence of danger. It is mainly applicable to municipal road construction, construction engineering construction, etc. The safety reminder device includes a support assembly 10, a reminder sign 20, and a transmission mechanism 30, a wind drive mechanism 40, and an electric drive mechanism 50 arranged on the support assembly 10. The reminder sign 20 is arranged on the transmission mechanism 30. The wind drive mechanism 40 and the electric drive mechanism 50 are both connected to the transmission mechanism 30. The wind drive mechanism 40 or the electric drive mechanism 50 drives the transmission mechanism 30 to move, thereby driving the reminder sign 20 to move.

[0025] In the safety reminder device provided by the embodiment of the present application, the wind drive mechanism 40 or the electric drive mechanism 50 drives the transmission mechanism 30 to move, so as to drive the reminder sign 20 to move. By making the reminder sign 20 move, it is easy to attract the attention of passers-by, and can play a good reminder role, thereby effectively avoiding the occurrence of danger. By setting up two independent driving mechanisms, the wind drive mechanism 40 and the electric drive mechanism 50, in a windless environment, the transmission mechanism 30 can be driven to move by the electric drive mechanism 50, and in a windy environment, the transmission mechanism 30 can be driven to move by the wind drive mechanism 40. Compared with relying solely on electric power to drive, a large amount of electric energy can be saved, achieving the purpose of energy saving and consumption reduction.

[0026] In another embodiment of the present application, Figure 1 and Figure 2 As shown, the transmission mechanism 30 includes a rotating member 31 and a linear moving member 32. The rotating member 31 is connected to the electric drive mechanism 50 and the wind drive mechanism 40, and is driven to rotate by the electric drive mechanism 50 or the wind drive mechanism 40. The linear moving member 32 is slidably connected to the rotating member 31. The rotation of the rotating member 31 can drive the linear moving member 32 to move linearly along the axis of the rotating member 31. The prompt sign 20 is connected to the linear moving member 32. When the electric drive mechanism 50 or the wind drive mechanism 40 drives the rotating member 31 to rotate, the sliding cooperation between the rotating member 31 and the linear moving member 32 can convert the rotational motion of the rotating member 31 into the linear motion of the linear moving member 32. The linear moving member 32 drives the prompt sign 20 to move linearly along the axis of the rotating member 31, thereby playing a prompting role. The rotating member 31 can be arranged vertically, horizontally, or inclined. When the rotating member 31 is arranged vertically, the linear moving member 32 and the prompt sign 20 move linearly in the vertical direction. When the rotating member 31 is arranged horizontally, the linear moving member 32 and the prompt sign 20 move linearly in the horizontal direction. When the rotating member 31 is arranged inclined, the linear moving member 32 and the prompt sign 20 move linearly at an angle to the horizontal plane.

[0027] Furthermore, the outer circumferential surface of the rotating member 31 is provided with a first thread groove and a second thread groove with the same pitch and opposite rotation direction. The first thread groove and the second thread groove are connected end to end to form a closed channel. The linear moving member 32 is partially embedded in the closed channel and is slidably connected with the closed channel. Assuming that the rotating member 31 is initially located in the first thread groove, the rotating member 31 keeps rotating in the same direction. When the rotating member 31 rotates, the linear moving member 32 will slide in the first thread groove and move linearly in the first direction along the axis of the rotating member 31. When the linear moving member 32 slides to the end of the first thread groove, it will automatically enter the second thread groove, then slide in the second thread groove, and move linearly in the opposite direction of the first direction along the axis of the rotating member 31. When the linear moving member 32 slides to the end of the second thread groove, it will automatically enter the first thread groove again, and the reciprocating cycle will be realized. In this way, the reciprocating linear motion of the linear moving member 32 is realized without changing the rotation direction of the rotating member 31, so that the linear moving member 32 drives the prompt sign 20 to move reciprocatingly.

[0028] Specifically, the rotating member 31 may be a reciprocating screw.

[0029] Furthermore, the linear moving member 32 includes a connecting sleeve and a slider disposed on the connecting sleeve, the connecting sleeve is movably mounted on the rotating member 31, and the slider is embedded in the closed groove and slidably connected with the closed groove. When the rotating member 31 rotates, the slider will slide in the closed groove on the one hand, and on the other hand, it will drive the connecting sleeve to move linearly along the axis of the rotating member 31, and the connecting sleeve can make the linear moving member 32 more stable and less likely to shake when moving linearly by being mounted on the rotating member 31.

[0030] Furthermore, if Figure 1 and Figure 2 As shown, the transmission mechanism 30 further includes a fixed rod 33, which is disposed on the support assembly 10 and extends along the axis direction of the rotating member 31, and the linear moving member 32 is slidably sleeved on the fixed rod 33. When the rotating member 31 rotates, the fixed rod 33 guides the linear moving member 32, and can ensure that the linear moving member 32 moves linearly along the axis of the rotating member 31, and does not rotate with the rotation of the rotating member 31.

[0031] In some other embodiments, the outer circumferential surface of the rotating member 31 may be provided with only one thread groove, and the linear moving member 32 is partially embedded in the thread groove and slidably connected with the thread groove. The rotating member 31 rotates in the same direction to drive the linear moving member 32 to move linearly in a single direction along the axis of the rotating member 31. By continuously switching the rotation direction of the rotating member 31, the reciprocating linear movement of the linear moving member 32 can also be achieved.

[0032] Of course, an external thread may also be provided on the outer circumference of the rotating member 31, and the linear moving member 32 is sleeved on the rotating member 31. The inner wall of the linear moving member 32 is provided with an internal thread, and the internal thread and the external thread are slidably matched. The rotating member 31 rotates in the same direction to drive the linear moving member 32 to move linearly in a single direction along the axis of the rotating member 31. By continuously switching the rotation direction of the rotating member 31, the reciprocating linear movement of the linear moving member 32 can also be achieved. Specifically, the rotating member 31 can be a screw rod, and the linear moving member 32 can be a nut.

[0033] In another embodiment of the present application, Figure 1 and Figure 2 As shown, the transmission mechanism 30 also includes a mounting tube 34 and a rotating rod 35. The mounting tube 34 is arranged on the linear moving member 32. The rotating rod 35 is movably arranged through the mounting tube 34 and can rotate in the mounting tube 34. One end of the rotating rod 35 extends out of the mounting tube 34 and is connected to the prompt sign 20. It can be understood that the connection between the prompt sign 20 and the linear moving member 32 mentioned above is an indirect connection here, that is, the prompt sign 20 is connected to the linear moving member 32 through the rotating rod 35 and the mounting tube 34. On the one hand, the rotation of the rotating member 31 can drive the linear moving member 32 to move linearly, and the linear moving member 32 can then drive the mounting tube 34, the rotating rod 35 and the prompt sign 20 to move linearly together. On the other hand, the prompt sign 20 can be driven to rotate by rotating the rotating rod 35, so that the prompt sign 20 can achieve two forms of movement, linear movement and rotational movement, to enhance the prompting effect.

[0034] Furthermore, if Figure 1 and Figure 2As shown, the transmission mechanism 30 also includes a swinging member 36 and a guide member 37. One end of the rotating rod 35 away from the prompt sign 20 extends out of the mounting tube 34 and is connected to one end of the swinging member 36. The guide member 37 is arranged on the support assembly 10. The guide member 37 is provided with a guide structure, which is zigzag and slidably connected to the other end of the swinging member 36. When the rotating member 31 rotates, the linear moving member 32 drives the mounting tube 34, the rotating rod 35 and the prompt sign 20 to move linearly together. When the rotating rod 35 moves linearly, it drives the swinging member 36 to slide on the guide structure. Since the guide structure is zigzag, the swinging member 36 will swing back and forth around the axis of the rotating rod 35 while moving linearly. The reciprocating swing of the swinging member 36 will drive the rotating rod 35 to rotate alternately in the clockwise and counterclockwise directions, thereby driving the prompt sign 20 to rotate alternately in the clockwise and counterclockwise directions, so that the prompt sign 20 can simultaneously perform linear movement and rotational motion. Through the cooperation of the swinging member 36 and the guide member 37, the combined linear movement and rotational movement of the prompt sign 20 can be realized. The power required for the linear movement and rotational movement of the prompt sign 20 is derived from the electric drive mechanism 50 or the wind drive mechanism 40. There is no need to additionally configure a drive mechanism for the rotational movement of the prompt sign 20, thereby greatly reducing production costs and saving electricity.

[0035] Specifically, the guide member 37 is rod-shaped, and a plurality of convex surfaces 371 and a plurality of concave surfaces 372 are provided on the side wall of the guide member 37. The plurality of convex surfaces 371 and the plurality of concave surfaces 372 are alternately arranged along the axial direction of the rotating member 31 to form a zigzag guide structure. During the axial linear movement of the swinging member 36 along the rotating member 31, the swinging member 36 continuously and alternately contacts the convex surfaces 371 and the concave surfaces 372, driving the rotating rod 35 to rotate alternately in the clockwise and counterclockwise directions, thereby driving the prompt sign 20 to rotate alternately in the clockwise and counterclockwise directions.

[0036] For ease of understanding, Figure 2 and Figure 1As shown, it is assumed that the rotating member 31 is arranged vertically up and down, the rotating rod 35 is arranged horizontally left and right, and the guide member 37 is arranged vertically. The guide member 37 bulges forward to form a convex curved surface 371, and the guide member 37 is recessed to form a concave curved surface 372. Taking the position of the swing member 36 shown in the figure as the initial point, when the rotating rod 35 moves linearly downward, it will drive the swing member 36 to slide downward along the convex curved surface 371. Before sliding down to the crest of the convex curved surface 371, the swing member 36 will swing forward while sliding down, that is, rotate in the clockwise direction, and drive the prompt sign 20 to swing forward through the rotating rod 35. When the swing member 36 passes the crest of the convex curved surface 371, under the influence of gravity, the prompt sign 20 and the swing member 36 will swing backward, that is, rotate in the counterclockwise direction. The swing member 36 transitions from the convex curved surface 371 to the concave curved surface 372, and then enters the next convex curved surface 371, and repeats, so that the prompt sign 20 can swing back and forth.

[0037] Furthermore, if Figure 1 and Figure 2 As shown, the transmission mechanism 30 further includes a torsion spring 38, which is connected between the mounting tube 34 and the rotating rod 35. Figure 2 The position of the swinging member 36 shown in the figure is the initial point. When the rotating rod 35 moves linearly downward, the swinging member 36 will be driven to slide downward along the convex surface 371. Before sliding down to the crest of the convex surface 371, the swinging member 36 will overcome the tension of the torsion spring 38 and swing forward while sliding down, that is, rotate in a clockwise direction, and drive the prompt sign 20 to swing forward through the rotating rod 35. After the swinging member 36 passes over the crest of the convex surface 371, the swinging member 36 will swing backward under the tension of the torsion spring 38, that is, rotate in a counterclockwise direction, and drive the prompt sign 20 to swing backward through the rotating rod 35. The swinging member 36 transitions from the convex surface 371 to the concave surface 372, and then enters the next convex surface 371, and repeats this process. In this way, the prompt sign 20 can swing back and forth.

[0038] In some other embodiments, the guide structure may also be a guide groove, and the end of the swing member 36 away from the rotating rod 35 extends into the guide groove and is slidably connected to the guide groove. The setting of the guide groove can make the swing member 36 more stable and smooth when swinging and less likely to shake.

[0039] In another implementation of the present application, Figure 1 and Figure 2As shown, the wind driving mechanism 40 includes a rotating head 41, a connecting rod 42 and a windward member 43. The rotating head 41 is connected to one end of the rotating member 31, one end of the connecting rod 42 is connected to the rotating head 41, and the other end of the connecting rod 42 is connected to the windward member 43. In a windy environment, the wind forces drive the windward member 43 to rotate, and the windward member 43 drives the rotating head 41 to rotate through the connecting rod 42, and the rotating head 41 drives the rotating member 31 to rotate, thereby realizing the linear movement of the linear moving member 32 and the prompt sign 20. The connecting rod 42 plays a role in increasing the force arm, making it easier and more labor-saving when the rotating head 41 rotates.

[0040] Further, the number of the windward members 43 can be one or more, and the plurality of windward members 43 are arranged at intervals along the circumference of the rotating head 41. In this embodiment, the number of the windward members 43 is two, and the two windward members 43 are arranged at intervals relative to each other. Specifically, the two windward members 43 are symmetrically arranged with the rotating head 41 as the center, and each windward member 43 is connected to the rotating head 41 through a connecting rod 42.

[0041] Furthermore, if Figure 2 As shown, the windward member 43 has a windward surface and a leeward surface that are arranged opposite to each other, and a groove 431 is provided on the windward surface, and the groove 431 can concentrate wind force, so that the rotating head 41 can rotate more easily and labor-savingly. When there are multiple windward members 43, the windward surface of the windward member 43 faces the leeward surface of one of the adjacent windward members 43, ensuring that the recessed directions of the grooves 431 of each windward member 43 are in the same clockwise direction, so that the rotating head 41 can rotate more easily and labor-savingly.

[0042] Furthermore, the windward component 43 is a ball bowl, which is hemispherical, with the plane of the ball bowl being the windward side and the hemispherical surface of the ball bowl being the leeward side.

[0043] In another embodiment of the present application, Figure 1 and Figure 2 As shown, the electric drive mechanism 50 includes a power supply 51 and a motor 52, both of which are arranged on the support assembly 10, the power supply 51 is electrically connected to the motor 52, and the output end of the motor 52 is connected to the rotating member 31. The power supply 51 provides electric energy to the motor 52, and the motor 52 can drive the rotating member 31 to rotate after being energized, thereby realizing the linear motion of the linear moving member 32 and the prompt sign 20. Specifically, the output end of the motor 52 is connected to the end of the rotating member 31 away from the rotating head 41.

[0044] Furthermore, if Figure 1 and Figure 2As shown, the electric drive mechanism 50 further includes a switch assembly, which includes a first conductive member 53 fixed on the connecting rod 42 and a second conductive member 54 slidably mounted on the connecting rod 42. The first conductive member 53 is electrically connected to one of the power source 51 and the motor 52, and the second conductive member 54 is electrically connected to the other of the power source 51 and the motor 52. The second conductive member 54 is located between the first conductive member 53 and the windward member 43. The cooperation between the first conductive member 53 and the second conductive member 54 plays the role of a circuit switch. Specifically, when the first conductive member 53 contacts the second conductive member 54, the circuit between the power source 51 and the motor 52 is turned on, and the current of the power source 51 can flow to the motor 52 through the first conductive member 53 and the second conductive member 54, and the motor 52 is powered on and starts to work. When the first conductive member 53 is separated from the second conductive member 54, the circuit between the power source 51 and the motor 52 is disconnected, and the current of the power source 51 cannot flow to the motor 52, and the motor 52 is powered off and stops working.

[0045] Specifically, in a windless environment, the second conductive member 54 is in the initial position, in contact with the first conductive member 53, the circuit between the power supply 51 and the motor 52 is turned on, and the rotating member 31 is driven to rotate by the motor 52. In a windy environment, the windward member 43 drives the rotating head 41 to rotate through the connecting rod 42 under the action of wind, and the second conductive member 54 slides on the connecting rod 42 in a direction away from the first conductive member 53 under the action of centrifugation and separates from the first conductive member 53, the circuit between the power supply 51 and the motor 52 is disconnected, the motor 52 is powered off and stops working, and at this time, the rotating member 31 is driven to rotate by the rotating head 41. In this way, in a windy environment, the electric drive is automatically switched to the wind drive, and there is no need to manually cut off the power, which is simple and quick to operate.

[0046] It should be noted that the windless environment mentioned in the embodiment of the present application does not mean that there is no wind at all, but refers to that the wind force of the actual natural wind is less than the minimum wind force that drives the windward member 43 to rotate. When the wind force of the actual natural wind is greater than or equal to the minimum wind force that drives the windward member 43 to rotate, it is a windy environment. It can also be judged from the actual state of the windward member 43. When the windward member 43 is in a stationary state, it is a windless environment, and when the windward member 43 is in a rotating state, it is a windy environment.

[0047] Furthermore, if Figure 2As shown, the height of the connecting rod 42 gradually decreases from the windward member 43 to the first conductive member 53. In a windy environment, the windward member 43 drives the rotating head 41 to rotate through the connecting rod 42 under the action of wind force, and the second conductive member 54 overcomes its own gravity and the friction between the connecting rod 42 under the centrifugal action, slides along the connecting rod 42 in the direction close to the windward member 43, and separates from the first conductive member 53, the circuit between the power supply 51 and the motor 52 is disconnected, the motor 52 is powered off and stops working, and the rotating member 31 is driven to rotate by the rotating head 41. In a windless environment, the rotating head 41 stops rotating, and the second conductive member 54 slides on the connecting rod 42 in the direction away from the windward member 43 under the action of gravity until it contacts the first conductive member 53, the circuit between the power supply 51 and the motor 52 is connected, the motor 52 is powered on and starts working, and the rotating member 31 is driven to rotate by the motor 52. In this way, it is realized that in a windless environment, the wind-driven drive is automatically switched to the electric-driven drive, and there is no need for manual operation to power on, and the operation is simple and fast.

[0048] Furthermore, if Figure 1 and Figure 2 As shown, the electric drive mechanism 50 further includes a first elastic contact piece 55 and a first conductor disc 56, the first elastic contact piece 55, the first conductor disc 56 and the first conductive member 53 are electrically connected in sequence, the electric drive mechanism 50 further includes a second elastic contact piece 57 and a second conductor disc 58, the second elastic contact piece 57, the second conductor disc 58 and the second conductive member 54 are electrically connected in sequence, one electrode of the power source 51 is connected to one electrode of the motor 52, the other electrode of the power source 51 is connected to one of the first elastic contact piece 55 and the second elastic contact piece 57, and the other electrode of the motor 52 is connected to the other of the first elastic contact piece 55 and the second elastic contact piece 57. Exemplarily, the positive electrode of the power source 51 is connected to the positive electrode of the motor 52, the negative electrode of the motor 52 is connected to the first elastic contact piece 55, and the second elastic contact piece 57 is connected to the negative electrode of the power source 51. During operation, the current of the power supply 51 flows out from the positive electrode, then passes through the motor 52, the first elastic contact piece 55, the first conductor disk 56, the first conductive member 53, the second conductive member 54, the second conductor disk 58 and the second elastic contact piece 57 in sequence, and then flows back to the negative electrode of the power supply 51 to form a loop.

[0049] Furthermore, if Figure 1 and Figure 2As shown, the first elastic contact piece 55 and the second elastic contact piece 57 are arranged on the support assembly 10 at intervals, and the first conductor disc 56 and the second conductor disc 58 are arranged on the rotating head 41 at intervals. The rotation of the rotating head 41 can drive the first conductor disc 56 and the second conductor disc 58 to rotate. When the first conductor disc 56 rotates, it slides in contact with the first elastic contact piece 55, and when the second conductor disc 58 rotates, it slides in contact with the second elastic contact piece 57. It can be understood that the first elastic contact piece 55 and the second elastic contact piece 57 replace the wires to be slidably connected with the first conductor disc 56 and the second conductor disc 58, respectively, so that when the rotating head 41 drives the first conductor disc 56 and the second conductor disc 58 to rotate, the first elastic contact piece 55 and the second elastic contact piece 57 are arranged on the support assembly 10, and do not rotate with the first conductor disc 56 and the second conductor disc 58, but remain motionless, effectively preventing the wire from tangling.

[0050] Furthermore, the first conductor disc 56 is electrically connected to the first conductive member 53 through a conductive wire, and the second conductor disc 58 is electrically connected to the second conductive member 54 through a conductive wire.

[0051] In another embodiment of the present application, Figure 1 and Figure 2 As shown, the support assembly 10 includes a support frame 11 and a mounting plate 12, the motor 52 and the power supply 51 are both arranged on the support frame 11, the mounting plate 12 and the support frame 11 are spaced apart, the rotating member 31, the fixing rod 33 and the guide member 37 are all arranged between the mounting plate 12 and the support frame 11, the rotating head 41 is arranged on the side of the mounting plate 12 away from the rotating member 31, the mounting plate 12 is provided with a hole for connecting the rotating head 41 with the rotating member 31, and the first elastic contact piece 55 and the second elastic contact piece 57 are spaced apart on the mounting plate 12.

[0052] Furthermore, if Figure 2 As shown, universal wheels 13 are provided at the bottom of the support frame 11 to facilitate movement.

[0053] Furthermore, the support frame 11 is provided with two independent cavities, and the motor 52 and the power supply 51 are respectively accommodated in the two cavities. By accommodating the motor 52 and the power supply 51 in the cavities, the motor 52 and the power supply 51 can be protected to prevent the external wind and rain from affecting the operation of the motor 52 and the power supply 51.

[0054] In another embodiment of the present application, Figure 2As shown, the safety reminder device also includes a clutch mechanism 60, which is arranged between the rotating member 31 and the rotating head 41, and is used to control the power transmission between the rotating member 31 and the rotating head 41. In a windless environment, the rotating member 31 is driven to rotate by the motor 52, and the clutch mechanism 60 can be controlled to cut off the power transmission between the rotating member 31 and the rotating head 41. The rotating head 41, the connecting rod 42 and the windward member 43 do not rotate with the rotation of the rotating member 31, that is, the motor 52 only needs to drive the rotating member 31 to rotate, and does not need to drive the rotating head 41, the connecting rod 42 and the windward member 43 to rotate, thereby reducing the loss of electric energy and achieving the purpose of energy saving and consumption reduction. In a windy environment, the windward member 43 drives the rotating head 41 to rotate through the connecting rod 42, and the clutch mechanism 60 can be controlled to restore the power transmission between the rotating member 31 and the rotating head 41. The power of the rotating head 41 is transmitted to the rotating member 31 through the clutch mechanism 60, thereby driving the rotating member 31 to rotate, and realizing the movement of the reminder sign 20.

[0055] Furthermore, the clutch mechanism 60 is an overrunning clutch, which has the function of self-clutching by utilizing the speed change or the change of the rotation direction of the master and slave parts. Specifically, in a windless environment, the rotating member 31 is driven to rotate by the motor 52, and the overrunning clutch can automatically switch to a disengaged state, thereby cutting off the power transmission between the rotating member 31 and the rotating head 41; in a windy environment, the windward member 43 drives the rotating head 41 to rotate through the connecting rod 42, and the overrunning clutch can automatically switch to a closed state, thereby restoring the power transmission between the rotating member 31 and the rotating head 41. By setting an overrunning clutch to automatically control the power transmission between the rotating member 31 and the rotating head 41, the operation is easier and more labor-saving.

[0056] Furthermore, the clutch mechanism 60 is disposed on the mounting plate 12 .

[0057] In another embodiment of the present application, the shape of the sign 20 is not limited, and may be square, rectangular, circular, triangular, etc.

[0058] Furthermore, the sign 20 may have markings such as text, letters, numbers, symbols, patterns or colors.

[0059] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
