DETAILED DESCRIPTION

[0020] The side of the protection plate 141 away from the lamp pole 11 adopts an arc edge design to avoid damage to the ball, and a ventilation hole 142 is opened inside the protection plate 141.

[0021] The fixing part 15 includes a reciprocating rod 151. The lamp pole 11 adopts a hollow structure design. The lamp pole 11 is slidably connected to the circumferential outer wall of the reciprocating rod 151 through a through groove opened inside it. A rubber block is fixedly connected to the side of the reciprocating rod 151 close to the protective plate 141. The rubber block undergoes a certain deformation when it contacts the reciprocating rod 151 and can also play a role in shock absorption and protection.

[0022] The side of the reciprocating rod 151 away from the protective plate 141 adopts an inclined surface design. The lamp pole 11 is rotatably connected to the rotating cylinder 152 through a bearing arranged inside it. The circumferential outer surface of the rotating cylinder 152 is fixedly connected to a limiting ring 153 that fits the inclined surface of the reciprocating rod 151.

[0023] The bottom end of the rotating drum 152 is fixedly connected with a gear 154 , and a driving seat is provided inside the base which is transmission-connected with the outer surface of the gear 154 .

[0024] A placement groove 111 is provided on the circumferential outer surface of the lamp pole 11, and the placement groove 111 includes an upper groove 1111 and a lower groove 1112. The upper groove 1111, the through groove and the lower groove 1112 are distributed in sequence from top to bottom. The upper surface of the protective plate 141 is fixedly connected to a top plate 155 that fits the inner wall of the upper groove 1111, and the lower surface of the protective plate 141 is fixedly connected to a bottom plate 156 that fits the inner wall of the lower groove 1112.

[0025] The top plate 155 is designed to be inclined, and the top plate 155 is lower on the side close to the lamp pole 11 .

[0026] An anti-slip strip 1551 is fixedly connected to the upper surface of the top plate 155 , and the top plate 155 , the bottom plate 156 and the protective plate 141 are integrally formed.

[0027] In practical applications, the lighting lamp body 1 is suitable for sports stadiums, and the lamp pole 11 plays a supporting role and performs column-type suspension on the lamp head 12.

[0028] The process of protecting the structure 14 to reduce shock: In sports fields, such as basketball and volleyball, where high-intensity sports are played, the ball will inevitably touch the lamp pole 11, causing severe vibration to the lamp pole 11 and damaging the stability of the lamp pole 11. The high-speed collision of the ball will cause the lamp head 12 above the lamp pole 11 to shake, affecting the line of sight of the athletes on the field and causing dizziness to the athletes. Long-term collisions will also cause the light bulb inside the lamp head 12 to loosen or have poor contact. Therefore, a protective structure 14 is needed to protect the lamp pole 11 and the lamp head 12 to absorb the force of the instantaneous impact of the ball.

[0029] There are multiple groups of protective plates 141 in the vertical direction. Several protective plates 141 in each group are distributed in a circular array with the lamp pole 11 as the axis. There is a certain gap between the protective plates 141. In the initial state, the protective plates 141 are perpendicular to the ground under the action of the elastic member 145 between the inner side and the lamp pole 11, and the inner side of the protective plate 141 is tangent to the circumferential direction of the lamp pole 11. The protective plate 141 has a certain distance from the circumferential outer surface of the lamp pole 11. The elastic member 145 is located around the protective plate 141 and is in an expanded state. When the lighting lamp body 1 is used in the stadium, when the ball hits the lamp pole 11, the ball will contact the protective plate 141 in the external protection structure 14.

[0030] Since the length of the protection plate 141 is greater than the diameter of the sphere, and the impact of the sphere is uncertain and may hit the protection plate 141 at various angles, the protection structure 14 must have the ability to effectively reduce shock when impacts occur at different locations.

[0031] When the ball hits the upper position of the outer surface of the protective plate 141, the two elastic members 145 at the top begin to compress, and the protective plate 141 rotates with the support shaft 144 as the axis. When the distance between the upper part of the protective plate 141 and the surface of the lamp pole 11 is smaller than the distance between the lower part of the protective plate 141 and the surface of the lamp pole 11, the two elastic members 145 at the top are in a compressed state, absorbing the impact force caused by the ball collision, and dispersing it to various parts of the lamp pole 11 in the circumferential direction through the annular plate 13, thereby dispersing more impact, thereby achieving a shock-absorbing effect, ensuring the stability of the light and the stability of the structure of the lamp pole 11. When the impact force is the greatest, the elastic member 145 at the top is in a fully compressed state, and the top plate 155 enters the upper slot 1111, and the protective plate 141 has a maximum inclination angle.

[0032] When the ball hits the side of the outer surface of the protective plate 141, the two springs on the inner side of the protective plate 141 begin to compress, and the ball exerts a greater force on one side of the protective plate 141. The support shaft 144 follows the protective plate 141 under the action of the ball, and the side with greater force approaches the outer surface of the lamp pole 11, and the distance between the support shaft 144 on this side and the annular plate 13 becomes smaller (the outer end of the connecting rod 143 is rotatably connected to the outer end of the supporting shaft 144, and the end of the connecting rod 143 away from the supporting shaft 144 can be rotatably connected to the annular plate 13 through a pin, and at the same time, the connecting rod 143 can also slide in the internal groove of the annular plate 13 through the pin), and the connecting rod 143 can adapt to the different collision forces of the ball, and rotate and slide a certain angle and distance in the groove. The elastic member 145 on this side is deformed to absorb the impact force caused by the ball collision, and disperse it to various parts of the circumferential direction of the lamp pole 11 through the annular plate 13, so as to disperse more impact, thereby achieving a shock-absorbing effect and reducing the impact on the lamp holder 12.

[0033] When the ball hits the center of the outer surface of the protective plate 141, the distance between the protective plate 141 and the surface of the lamp pole 11 becomes shorter due to the impact of the ball, and the connecting rod 143 behind the protective plate 141 tilts. At the same time, the elastic member 145 behind the protective plate 141 is under pressure to absorb the impact force, and the protective plate 141 remains vertical to the ground and moves closer to the axis of the lamp pole 11. The force is more evenly transmitted to the annular plate 13 and the elastic member 145, so that they can work together better to absorb and disperse the impact force.

[0034] When the ball hits the position between the four protective plates 141, the four protective plates 141 are respectively located at the upper left position, the lower left position, the upper right position, and the lower right position, and the ball is located between them. Taking the upper left protective plate 141 as an example, the impact force on the lower right corner of the protective plate 141 is relatively large, and the elastic member 145 corresponding to the lower right corner of the protective plate 141 is deformed, and the protective plate 141 rotates downward with the support shaft 144 as the center, and the distance between the lower half of the protective plate 141 and the lamp pole 11 becomes shorter. The right side of the support shaft 144 is squeezed, and the rotation angle and position distance of the right connecting rod 143 change, so that the distance between the right half of the protective plate 141 and the surface of the lamp pole 11 becomes shorter, and the lower right corner of the protective plate 141 as a whole tilts toward the lamp pole 11. The elastic members 145 at the center of the four protective plates 141 absorb the impact force caused by the ball collision at the same time, and disperse it to various parts of the circumferential direction of the lamp pole 11 through the annular plate 13.

[0035] In the above process, the elastic member 145, when deformed by pressure, converts part of the energy generated by the impact of the ball into its own elastic potential energy. According to the law of conservation of energy, after the kinetic energy of the impact of the ball is transmitted to the protective plate 141, part of it causes the protective plate 141, the connecting rod 143, etc. to move and deform, and the other part is absorbed by the elastic member 145 and stored as elastic potential energy. This energy absorption effect of the elastic member 145 reduces the energy transmitted to other parts of the entire structure, thereby achieving a shock-absorbing effect, and the ball can quickly return to its original state after the impact ends.

[0036] The process of fixing the protective plate 141 using the fixing member 15: In windy weather, the wind speed increases sharply, and the wind load on the lamp pole 11 will increase significantly. The strong wind will generate a horizontal force on the lamp pole 11, causing the lamp pole 11 to shake, tilt or even break.

[0037] A driving seat is provided inside the base, which is relatively sealed with the outside of the lamp pole 11. Initially, the reciprocating rod 151 is contracted inside the lamp pole 11. The diameters of both ends of the reciprocating rod 151 are larger than the diameter of the through groove, limiting the maximum displacement. The inclined end of the reciprocating rod 151 is at the innermost side of the outer surface inclined surface of the limiting ring 153 and does not contact the outer surface of the limiting ring 153.

[0038] In windy weather, the manager can open the driving seat inside the base, drive the rotating drum 152 to rotate through the gear 154, and the limiting ring 153 will rotate together. During the rotation process, the inclined surface of the limiting ring 153 will contact the outer surface of the reciprocating rod 151, and the distance between the inclined surface of the limiting ring 153 and the through slot will gradually decrease. Under the extrusion of the limiting ring 153, the reciprocating rods 151 move toward the outside of the lamp pole 11 at the same time. The rubber block at the top of the reciprocating rod 151 will contact the inner side of the protective plate 141. As the reciprocating rod 151 extends farther, the protective plate 141 will rotate around the supporting shaft 144.

[0039] There are multiple groups of protective plates 141 arranged in the vertical direction. Each group of protective plates 141 is arranged in a circular array with the lamp pole 11 as the center. Each group of protective plates 141 is equipped with two limit rings 153 and two layers of reciprocating rods 151. The initial positions of the two limit rings 153 are different and they are staggered. If any reciprocating rod 151 is in the upper half of the protective plate 141 near the top plate 155, then the reciprocating rod 151 in the adjacent protective plate 141 is in the lower half near the bottom plate 156. When the two staggered limit rings 153 rotate at the same time, multiple protective plates 141 at the same axial position will be driven to tilt upward (the bottom plate 156 enters the lower card slot 1112 and fits with its inner wall), or open downward at the same time (the top plate 155 enters the upper card slot 1111 and fits with its inner wall). The protection plates 141 in the same longitudinal row rotate in the same direction, and the openings of adjacent longitudinal rows are opposite. The protection plates 141 with different opening directions are staggered in the circumferential direction.

[0040] When the largest diameter side of the limit ring 153 fits with the outer surface of the reciprocating rod 151, the rotation angle of the protective plate 141 is at the maximum value. At this time, the rotating drum 152 stops rotating and self-locks, and the bottom plate 156 of the protective plate 141 fits tightly with the inside of the lower slot 1112, or the top plate 155 of the protective plate 141 fits tightly with the inside of the upper slot 1111. At this time, the protective plate 141 is relatively fixed to the lamp pole 11 through the placement slot 111, and the components in the protective structure 14 have been locked and stuck, forming a structural system with multiple support points between the protective plate 141 and the lamp pole 11, which prevents the protective plate 141 from swinging or rotating without restriction in strong winds, and prevents the protective plate 141 from being damaged due to excessive swinging, or from colliding or rubbing with the lamp pole 11 and other components, thereby ensuring the integrity and stability of the protective plate 141 and the lamp pole 11 structure.

[0041] The rotation angles of the multiple axial protection plates 141 are staggered to avoid rotation in the same direction. While being stuck due to position limitations, they can also receive wind from multiple angles, so that the wind force on the lamp pole 11 is dispersed to different directions and positions, avoiding the lamp pole 11 from being subjected to excessive wind force on one side or in part, reducing the risk of the lamp pole 11 tilting or breaking due to concentrated force, and enhancing the overall stability of the lamp pole 11 in strong winds. The component forces generated by the wind force on the upward and downward tilted protection plates 141 can offset each other to a certain extent, reducing the net wind force on the lamp pole 11, just like the forces in multiple directions pulling and restraining each other, so that the lamp pole 11 stands more firmly in place.

[0042] The protective plates 141 with different inclinations can disrupt the airflow around the lamp pole 11, so that the airflow will not form a large-scale stable vortex when passing through the lamp pole 11, thereby reducing the wind noise caused by airflow vibration and vortex shedding, and reducing the noise interference of strong winds on the surrounding environment. From an aerodynamic point of view, this well-arranged layout of protective plates 141 optimizes the shape of the lamp pole 11, making the wind flow on the surface of the lamp pole 11 smoother. At the same time, a plurality of ventilation holes 142 are opened inside the protective plates 141, which can effectively reduce the wind resistance coefficient, thereby reducing the force of strong winds on the lamp pole 11, and improving the stability and safety of the lamp pole 11 in the wind.

[0043] The magnitude of the wind load on the lamp pole 11 is proportional to the windward area of ​​the lamp pole 11 . When the protective plate 141 is retracted, the windward area is reduced, and the wind load on the lamp pole 11 is also reduced accordingly.

[0044] The process of overhauling the lamp holder 12: When the lamp holder 12 at the top needs regular maintenance, the user can also climb the multi-layer protective plate 141 with the upper part tilted upward in the same axial range by fixing the protective structure 14. When the reciprocating rod 151 is in the upper part of the protective plate 141 close to the top plate 155, the reciprocating rod 151 slides outward, so that the distance between the top plate 155 and the lamp pole 11 in the protective plate 141 is greater than the distance between the bottom plate 156 and the lamp pole 11. At this time, the outer surface of the bottom plate 156 fits the inner wall of the lower slot 1112, and the upper surface of the top plate 155 in this state is parallel to the ground.

[0045] At this time, the guard plate 141 can be used as a climbing ladder. The user holds the two sides of the upper part of the guard plate 141 with both hands and steps on the upper surface of the top plate 155. The upper surface of the top plate 155 is fixed with an anti-slip strip 1551, which increases friction and improves safety. Because the outer surface of the bottom plate 156 is tightly fitted with the inner wall of the lower groove 1112, the gravity of the inclined guard plate 141 and the gravity of the staff will cause the bottom plate 156 to tend to be pressed against the bottom of the lower groove 1112, which will generate friction on the contact surface between the bottom plate 156 and the lower groove 1112. When external force tries to move or shake the plate, the friction will play a hindering role and resist the influence of external force, thereby enhancing the stability of the structure.

[0046] In summary, the lighting lamp body 1 has the following advantages: Advantage 1: When the ball hits the lamp pole 11, in the vertical direction, the protective plate 141 rotates around the support shaft 144, and the position and direction of itself and the elastic member 145 change to bear the impact of the ball. After absorbing a part of the elastic potential energy, it is transmitted to other parts of the entire structure through the annular plate 13; in the horizontal direction, the support shaft 144 is connected to the annular plate 13 through the connecting rod 143, and the connecting rod 143 can rotate and slide inside the slide groove, and can adapt to the impact of different strengths, and reduce shock through the synergy of the elastic member 145, the connecting rod 143 and other components; when the ball collides at the corner of the protective plate 141, the horizontal and vertical directions work together to meet the need for effective shockproof at different collision positions. In the sports field, it can cope with the impact of balls such as basketballs and volleyballs on the lamp pole 11, avoid the stability of the lamp pole 11 due to severe vibration, prevent the shaking of the lamp head 12 from affecting the athlete's vision, and reduce the occurrence of loose internal bulbs and poor contact.

[0047] Advantage 2: The protective plate 141 has multiple settings in both the circumferential direction and the vertical direction, which can protect the lamp pole 11 in all directions. Whether it is external force impact from different directions or potential threats at different heights, they can be effectively blocked by the multi-directional protective plate 141.

[0048] Advantage three: the limit ring 153 is driven to rotate by the driving member, so that the reciprocating rod 151 pushes the protective plate 141 to rotate and fits tightly with the inner wall of the placement groove 111 in the lamp pole 11, forming a multi-support point structural system, avoiding damage caused by excessive swinging or rotation of the protective plate 141 in strong winds, ensuring the integrity and stability of the protective plate 141 and the lamp pole 11 structure, and reducing the risk of the lamp pole 11 tilting or breaking due to wind loads.

[0049] Advantage 4: Multiple axial protective plates 141 are staggered in rotation angles, and can receive wind from multiple angles, so that the wind force on the lamp pole 11 is dispersed in different directions and positions, and the lamp pole 11 is prevented from being subjected to excessive wind force on one side or part of the lamp pole 11. The protective plates 141 with different tilt directions can disrupt the airflow around the lamp pole 11, reduce the wind noise caused by airflow vibration and vortex shedding, and reduce the noise interference to the surrounding environment; the ventilation holes 142 inside the protective plates 141 can effectively reduce the wind resistance coefficient, thereby reducing the force of strong wind on the lamp pole 11, and improving the stability and safety of the lamp pole 11 in the wind.

[0050] Advantage 5. When the lamp holder 12 needs to be inspected and repaired, the reciprocating rod 151 can be controlled to make the protective plate 141 with the upper part tilted upward in the same axial range as a climbing ladder, so that the staff can climb to the top to inspect the lamp holder 12. The upper surface of the top plate 155 in the protective plate 141 is fixed with an anti-slip strip 1551, which increases the friction and improves the safety of the staff when climbing; and the bottom plate 156 fits tightly with the inner wall of the lower groove 1112. The gravity of the protective plate 141 itself and the gravity of the staff will cause the bottom plate 156 to tend to be pressed against the inner wall of the lower groove 1112. The friction generated can resist external force and enhance the stability of the structure.

[0051] Advantage six: the driving seat drives the rotating drum 152 and the limiting ring 153 to rotate continuously, and the reciprocating rod 151 slides back and forth inside the through groove under the action of the limiting ring 153 and the elastic member 145. Correspondingly, the protective plate 141 also rotates with the supporting shaft 144 as the center point, and after tilting outward, it quickly returns to its original position and vibrates under the pulling force of the elastic member 145, so that the fallen leaves, dust, etc. on the outer surface of the protective plate 141 can be cleaned.

[0052] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
