It includes a spherical base and a surface magnet, a lamp post on the top of the spherical base, a solar traffic light group and a solar photovoltaic panel. The spherical base is supported by a single point and includes an upper hemisphere and a lower hemisphere. The upper hemisphere is buckled and connected to the lower hemisphere. The lower hemisphere is filled with counterweights, batteries and traffic lights. The two ends of the upper hemisphere surface are respectively provided with N-pole and S-pole permanent magnets. The spherical base rotates around a single connection point under the action of the earth's magnetic field, so that the solar photovoltaic panel is permanently facing south.

Although it can withstand certain external forces and wind forces, during use, once it encounters strong and continuous forces such as strong winds and heavy rains, it will still cause the temporary traffic lights to rotate and tilt, thereby causing passers-by to misunderstand the direction of the traffic signal, reducing the stability of the temporary traffic lights, and increasing the probability of traffic accidents; and once the traffic lights are tilted, maintenance personnel are required to check and adjust the counterweight of the spherical base and the position and support points of the base as needed to restore the traffic lights to normal working conditions. This process is relatively cumbersome and complicated, and increases labor intensity. Summary of the invention

[0008] A further improvement is that the spherical base is supported by a single point and comprises an upper hemisphere and a lower hemisphere, the upper hemisphere is buckled and connected with the lower hemisphere, and the lower hemisphere is filled with a counterweight, a battery and a signal machine.

[0009] A further improvement is that the annular metal tube is arranged horizontally, and the line connecting the annular center and the annular edge will produce an intersection with the spherical base shell. The line drawn from the intersection to the center of the sphere forms a connecting line, and the angle between the connecting line and the vertical center line of the spherical base is optimally 60° to 75°.

[0010] A further improvement is to set the outer diameter of the annular metal tube to R2 and the inner diameter to R1 (without considering the wall thickness), assuming that the diameter of the magnetic steel ball is approximately equal to the inner diameter of the annular metal tube, and setting the circumference of the ring to L, then .

[0011] A further improvement is that the number of magnetic steel balls that can be placed in the entire annular metal tube can be obtained according to L. .

[0012] A further improvement is that the coils are evenly arranged outside the annular metal tube, the length of each section is equal, and there is no interval between each two sections of the coils; the magnetic steel balls also have to reserve a movable amount in the annular metal tube, one section of the coil corresponds to one magnetic steel ball, and the length of each section of the coil is 3 times the diameter of the magnetic steel ball. The required number of coil sections is set to n, then , that is, the number of magnetic steel balls placed in the annular metal tube is also .

[0013] A further improvement is that when the direction indicated by the traffic light changes, the control system controls the input current direction of the coils in each section to be the same, and the magnetic steel balls will move in the same direction under the influence of the same magnetic field to adjust the direction indicated by the traffic light; when the traffic light tilts, the control system controls the current input direction of the coils in each section to drive the magnetic steel balls in the opposite direction of the tilt direction of the traffic light to adjust the tilt angle of the traffic light; when the traffic light is in an upright state and there is no error in the indication direction, the magnetic steel balls remain stationary and evenly distributed.

[0014] A further improvement is that the sensing device can be arranged in the middle position of the spherical base.

[0017] The beneficial effects of this application are:

[0018] The traffic signal light with the function of adjusting the rotation direction and tilt angle proposed in this application adopts two methods to achieve balance and adjustment:

[0019] First, the internal counterweight is used to balance the entire sphere, especially the weight of the solar photovoltaic panel on the top. High-density counterweights, such as non-magnetic metal particles, concrete, sand, etc., are set inside the base of the traffic light to provide sufficient weight and stability so that the traffic light can remain upright without external force. This design ensures the stability and anti-lodging ability of the traffic light.

[0020] Secondly, when the traffic light rotates and tilts due to strong external force, the sensing device senses the changes in the rotation direction and tilt angle of the traffic light, and adjusts the strength and direction of the magnetic field by controlling the on / off, size and direction of the current in the coil, thereby controlling the movement of the magnetic steel balls in the annular metal tube. All magnetic steel balls move in the same direction to adjust the rotation direction of the traffic light so that its set surface always faces due south and due north; when the steel balls move in a complex manner, they are used to adjust the tilt angle of the traffic light so that it can be restored and always remain in an upright state. Through this method, the traffic light can sense and feedback the influence of external interference factors such as strong winds in real time, so that the traffic light can maintain a stable working state and improve the safety and practicality of traffic sign facilities.

[0021] Through the above two methods, the traffic light described in this application has the function of adjusting the rotation direction and tilt angle, can effectively cope with external interference factors, improve the stability and anti-lodging ability of the traffic light, thereby increasing the safety and practicality of the traffic sign facilities.

[0032] The following will be combined with the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] like Figures 1 to 7 As shown, this embodiment proposes a traffic light with the function of adjusting the rotation direction and tilt angle, including a spherical base, a lamp post is installed above the spherical base, a traffic light box is installed on the top of the lamp post, a solar photovoltaic panel is installed above the light box, a horizontal annular metal tube is arranged along the inner surface of the spherical base, a plurality of magnetic steel balls are arranged inside the annular metal tube, coils are arranged in sections outside the annular metal tube, and a sensing device is also installed inside the spherical base; when the traffic light is subjected to strong external interference, the sensing device will sense the information of the change of the rotation direction and tilt angle of the traffic light, and feed it back to the control system, the control system controls the on-off, size and direction of the current in the coil to adjust the strength and direction of the magnetic field, thereby controlling the movement of the magnetic steel balls, and then realizing the automatic adjustment function of the traffic light, so that the traffic light returns to an upright state.

[0035] In this embodiment, the tumbler principle, Lenz's law and Lorentz's law are used to adjust the rotation direction and tilt angle of the traffic light. First, the design balances the overall sphere, especially the weight of the solar photovoltaic panel on the top, by using the internal counterweight of the spherical base. Secondly, when the traffic light rotates and tilts due to external strong force, the sensing device senses the changes in the rotation direction and tilt angle of the traffic light, and adjusts the strength and direction of the magnetic field by controlling the on / off, size and direction of the current in the coil, thereby controlling the movement of the magnetic steel ball in the annular metal tube.

[0036] In this embodiment, the spherical base 1 is a hollow metal sphere with a diameter of 1000mm, which is supported by a single point and can be divided into two parts from the horizontal central axis, namely the upper hemisphere 9 and the lower hemisphere 10, which are buckled and connected. A cover plate 12 is arranged inside the lower hemisphere 10, and a counterweight 11 is filled under the cover plate 12. The cover plate 12 is used to fix the counterweight 11 below. The counterweight 11 can be one of non-magnetic metal particles, concrete, cement, sand, and gravel. A mounting groove 13 is welded at the center of the lower hemisphere 10, and a battery and a signal machine are arranged inside the mounting groove 13, and the counterweight 11 is filled outside. The filling height of the counterweight 11 can be set to a maximum of 400mm, which is the vertical height from the support point of the spherical base 1 to the surface. After the counterweight 11 is filled, the entire traffic light remains upright without being affected by any external force.

[0037] In this embodiment, the upper hemisphere 9 and the lower hemisphere 10 are buckled and connected, one side is hinged and fixed, and the opposite side is locked and fixed, the hinged fixing method adopts an inner hinge connection and the lock is also set to be an inner lock, and the outer surface of the entire spherical base 1 remains smooth and tidy without external objects; the buckled part of the upper hemisphere 9 and the lower hemisphere 10 is also provided with a waterproof edge. This design can not only facilitate the installation and configuration and control the opening of the equipment, but also has high waterproof and dustproof sealing, and looks beautiful and generous.

[0038] The annular metal tube 6 is arranged horizontally, and the tangent line of the annular center and the annular edge will intersect with the outer shell of the spherical base 1. The line from the intersection to the center of the sphere forms a connecting line, and the angle between the connecting line and the vertical center line of the spherical base is preferably 60° to 75°. By properly arranging the position of the annular metal tube 6, the stability and wind resistance of the traffic light can be improved, the risk of tilting and rotation can be reduced, and the balance and endurance of the overall structure can be enhanced.

[0039] Assume that the outer diameter of the annular metal tube 6 is R2 and the inner diameter is R1 (without considering the wall thickness). Assume that the diameter of a single magnetic steel ball 8 is approximately equal to the inner diameter of the annular metal tube 6. Assume that the circumference of the ring is L. Then According to L, the total number of magnetic steel balls 8 that can be placed in the entire annular metal tube 6 can be calculated. The coils 7 are evenly arranged outside the annular metal tube 6, and the length of each section is equal. There is no gap between each section of the coils 7. The magnetic steel balls 8 are also reserved for movement in the annular metal tube 6. One section of the coil 7 corresponds to one magnetic steel ball 8. The length of each section of the coil 7 is three times the diameter of the magnetic steel ball 8. The number of sections of the coils 7 required is set to n, then , that is, the number of magnetic steel balls 8 placed in the annular metal tube 6 is also .

[0040] Each coil 7 has two ends, one end is the incoming line, and the other end is the outgoing line. Each coil 7 can be powered individually, or two or more coils 7 can be powered in series, and every two coils 7 are electrically connected. This design allows a variety of current values ​​to pass through the coil 7 to generate magnetic fields of different intensities. When a single coil 7 is powered individually, a larger current can be obtained by connecting the voltage to the taps on both sides of the single coil 7. When two or more coils 7 are powered in series, a smaller current can be obtained. Lenz's law shows that the strength of the magnetic field generated is related to the magnitude of the current. The larger the current, the stronger the magnetic field, and the faster the magnetic steel ball 8 moves; the smaller the current, the weaker the magnetic field, and the slower the magnetic steel ball 8 moves. For example Figure 3 As shown, according to Ampere's law, if you hold the solenoid in your right hand with four fingers pointing in the direction of the current, the thumb points in the direction of the N pole. In the three adjacent coils 7, by controlling the direction of the current flowing into the coils, the magnetic field direction of the middle coil 7 and the magnetic field direction of the coils 7 on both sides are mutually exclusive, and the magnetic steel ball 8 can be locked.

[0041] The magnetic steel ball mentioned in this embodiment does not specifically refer to a single magnetic steel ball. According to the actual control situation, it can be multiple magnetic steel balls or a single magnetic steel ball, collectively referred to as magnetic steel balls. The coil mentioned in this embodiment does not specifically refer to a single-segment coil. Multiple-segment coils and single-segment coils are collectively referred to as coils.

[0042] For the regulation of the indication direction of the traffic light, the control system obtains the current indication direction through the sensing device 14, and adjusts the magnitude and direction of the current of the input coil 7 according to the error between the current indication direction and the desired indication direction and the historical movement trajectory, so as to control the movement speed and direction of the magnetic steel ball 8, thereby adjusting the indication direction. For the regulation of the tilt angle of the traffic light, the control system obtains the current tilt angle through the sensing device 14, and adjusts the magnitude and direction of the current passing through the coil 7 according to the error between the current tilt angle and the desired tilt angle and the historical movement trajectory, so as to control the movement speed and direction of the magnetic steel ball 8, thereby adjusting the tilt angle.

[0043] like Figure 5 As shown, when the traffic light changes its indication direction due to external force, the control system controls the direction of the current passing through each segment of the coil 7 to be the same, and the direction of the magnetic field generated by each segment of the coil 7 is also the same, so each magnetic steel ball 8 will be attracted or repelled at the same time, and thus gathered together. Due to the continuous magnetic field, the gathered magnetic steel balls 8 move in the same direction under the action of the magnetic field. When the magnetic steel balls 8 move in the same direction at a certain speed, the traffic light will rotate as a whole, and finally restore the set surface to face due south and due north.

[0044] If the directions of the currents passing through the coils 7 are different, since the force of the magnetic field is related to the direction of the current, the magnetic steel ball 8 may be affected by the interaction force between the magnetic fields of different coils 7, resulting in different directions of movement. At this time, the magnetic steel ball 8 may be attracted to certain coils 7, or repelled from certain coils 7, thereby generating movements in different directions, causing the magnetic steel ball 8 to gather in one place or disperse evenly, and adjusting and maintaining the tilt state of the traffic light by weight compensation. When the traffic light is tilted, the control system controls the current input direction of each coil 8, drives the magnetic steel ball 8 to the opposite direction of the tilt direction of the traffic light, and uses the weight of the magnetic steel ball 8 itself to compensate for the deviation weight, which is used to adjust the tilt angle of the traffic light. Figure 6 This is a method for adjusting the tilt of the traffic light. Other control methods can also be used. The control system will send the most suitable control signal according to the actual situation. When the traffic light is in an upright state and there is no indication direction error, the magnetic steel balls 8 remain stationary and evenly distributed. When evenly distributed, the magnetic steel balls 8 can be controlled to be distributed independently, or multiple magnetic steel balls 8 can be distributed in groups.

[0045] In the embodiment provided in the present application, the annular metal tube 6 is arranged 10 mm away from the inner wall of the spherical base 1. Figure 2 Shown, take the connecting line and the vertical center line angle of the spherical base is 60 °;

[0046] but ;

[0047] If R1 is 394 mm, the diameter of the magnetic steel ball 8 is approximately 30 mm;

[0048] According to the formula , that is, the circumference of the annular metal tube 6 is 2568.52;

[0049] Assuming that the annular metal tube 6 is filled with magnetic steel balls 8, according to the formula , , should be a small integer and a multiple of 3 (to ensure that the three adjacent coils 7 can lock the magnetic steel ball 8 in the middle coil 7 position, such as Figure 3 ), that is, take N = 84, when the annular metal tube 6 is full, 84 magnetic steel balls 8 can be placed;

[0050] Reserve space for magnetic steel balls to move according to the formula , The number of segments should be a multiple of 3, that is, when the diameter of the magnetic steel ball 8 is 30 mm, the annular metal tube 6 is provided with 27 segments, and 27 magnetic steel balls 8 are placed inside.

[0051] like Figure 6As shown, the annular metal tube 6 is divided into 27 parts, each of which is a section of coil 7. When the position 100 of the traffic light is tilted downward, it means that the weight of the position 100 is heavier than the position of the opposite surface. At this time, the control system controls 100-900, 1900-2700 to lead the magnetic steel ball 8 to the opposite surface, that is, the position of 1400, to compensate for the deviation weight. The annular metal tube 8 can be divided into left and right parts from 100 and 2700, and the magnetic poles of the left and right parts are opposite. When the traffic light is in an upright state and stable, the distribution of the magnetic steel ball 8 can be as follows Figure 7 Arrangement shown (the weight of a single steel ball has little effect on the overall stability of the traffic light, and the presence of two magnetic steel balls gathering in one place can be ignored). Figure 7 It only represents one control method, and other arrangements can also be selected. For example, the control system divides the 27 magnetic steel balls 8 into 9 groups, with 3 in each group, that is, 3 magnetic steel balls 8 are controlled in one coil 7 in every three-segment coil 7, and the 9 groups of magnetic steel balls 8 are evenly distributed to the entire annular metal tube 6.

[0052] In this embodiment, the sensing device 14 is selected to sense the changes in the rotation direction and tilt angle of the signal light, and feeds this information back to the control system, which controls and adjusts the on / off, direction and size of the current of each coil 7. The sensing device 14 can be set in the middle position of the spherical base 1, so that omnidirectional detection can be achieved to provide reliable data output.
