Technical Field

The invention belongs to the technical field of billboards, and particularly relates to energy-saving three-face turning billboard equipment.

Background

The three-side turning billboard is an outdoor advertising medium and is formed from a group of side-by-side positioned triangular prisms. The three-face turning billboard enables all triangular prisms to rotate around a central shaft of the three-face turning billboard through PLC (programmable logic controller) control, motor drive and cam drive, and turns over in different forms and sequences according to a preset mode, and forms three dynamic pictures.

After the existing three-face turning billboard is used for a period of time, due to reasons such as mechanical abrasion and deformation, when a triangular prism rotates, pictures of the three-face turning billboard cannot be located on the same plane, and the display effect of the three-face turning billboard is affected. In addition, the three-face turning billboard is easy to deform or topple over due to overlarge stress in windy weather, and the use of the three-face turning billboard is seriously influenced.

The invention aims to provide a transmission mechanism of energy-saving three-face turning billboard equipment, which ensures that a triangular prism can be locked after rotating for 120 degrees, and ensures that pictures of the three-face turning billboard are always positioned on the same plane; meanwhile, the wind resistance of the three-face turning billboard is improved.

The invention designs an energy-saving three-face turning advertising board device which solves the problems.

The switching frequency of the three-face turning billboard is determined by a PLC system, and the PLC system controls the servo motor 7 to intermittently rotate for one circle.

The working process of the invention is as follows:

as shown in fig. 2, when all the triangular prisms 4 are turned over, stopped and stabilized, one side surfaces of all the triangular prisms 4 far from the vertical fixing plate 2 are in a coplanar state, and in this state, one side surfaces of all the triangular prisms 4 far from the vertical fixing plate 2 constitute a group of advertisements; when all the triangular prisms 4 are turned over again by 120 degrees, and are stopped and stabilized, one side surface of all the triangular prisms 4 far away from the vertical fixing plate 2 forms a group of advertisements. That is, after all the triangular prisms 4 are stopped and stabilized every 120 degrees of turning, the cooperation of all the triangular prisms 4 with each other can switch a set of advertisements. When a group of advertisements is formed by a side face, far away from the vertical fixing plate 2, of the triangular prism 4, under the condition, a smaller interval exists between two adjacent triangular prisms 4, and under the condition that the advertisement visual effect is not influenced, the two adjacent triangular prisms 4 can be guaranteed not to generate movement interference when being overturned.

The initial state of the three-face turning billboard is as follows: one side surface of all the triangular prisms 4 far away from the vertical fixing plate 2 forms a group of advertisements, and the specific state of any three-face turning mechanism in the state is as follows: as shown in fig. 15 and 16, the roller 29 is located in a recess between two adjacent cams 42 in the cam plate 27, and the roller 29 is in frictional contact with an outer disc surface of the recess; the first telescopic rod 25 and the first spring 28 are in a compressed state, and the second telescopic rod 30 and the second spring 31 are in a compressed state; one end of a second L-shaped plate 39 with a round corner 41 is inserted into the rectangular insert cylinder 32, and the opening of the rectangular insert cylinder 32 is in pressing contact with a baffle 40 on the second L-shaped plate 39; the other two ends of the second L-shaped plates 39 with the round corners 41 are slightly spaced from the corresponding side surfaces of the rectangular insert cylinder 32; as shown in fig. 14, the second swing plate 37 is vertically distributed with the adjacent first swing plate 35, and the plate spring 38 is in a natural state.

The invention relates to a process for switching advertisements by turning a three-face turning billboard: when the wind speed sensor identifies that the external wind speed is lower than the strong wind, the wind speed sensor transmits the identified external wind speed signal to the PLC control system, and the PLC control system analyzes the signal and then controls the servo motor 7 to drive the driving shaft 8 to rotate for one circle at the normal gap frequency. When the driving shaft 8 rotates for one circle, the driving shaft 8 drives the shifting column 15 to rotate for one circle through the driving plate 13, and the shifting column 15 enables the rotation angle of the grooved wheel 16 to be 60 degrees; the sheave 16 drives the first gear 10 through the first shaft 9 by a rotation angle of 60 °. Since the first gear 10 and the second gear 20 have the same size, the first gear 10 drives the second gear 20 to rotate by 60 degrees, and the other second gears 20 rotate by 60 degrees. Taking the process that any one of the second gears 20 rotates by 60 degrees to operate the three-face turning mechanism as an example: in the process of rotating the second gear 20 by 60 degrees, the second gear 20 drives the cam plate 27 and the first swing plate 35 to rotate by 60 degrees through the rotating sleeve 21, and the fixed block 36 moves along with the first swing plate 35; since the rectangular insert cylinder 32 limits one second L-shaped plate 39, the second rotating shaft 19 cannot rotate, so that the first swing plate 35 cannot drive the second rotating shaft 19 to rotate through the fixed block 36, the leaf springs 38 and the second swing plate 37 in the process of just starting to rotate the first swing plate 35, in the process, two leaf springs 38 are compressed, and the other two leaf springs 38 are stretched. Since the first spring 28 is in a compressed state, the roller 29 is in frictional contact with the outer disc surface of the cam disc 27, and then during the 60-degree rotation of the cam disc 27, the cam 42 on the cam disc 27 presses the roller 29, so that the roller 29 moves along the axis of the first telescopic rod 25 toward the fourth support 24, and thus the first L-shaped plate 26 moves toward the fourth support 24, and the first telescopic rod 25 and the first spring 28 continue to be compressed; the first L-shaped plate 26 drives the second spring 31 and the second telescopic rod 30 to move towards the fourth support 24, so that the second spring 31 and the second telescopic rod 30 gradually return to an uncompressed state, in which the openings of the rectangular insertion tubes 32 are in contact with the corresponding baffles 40 and there is substantially no pressure, and in the process, the second rotating shaft 19 still cannot rotate, two leaf springs 38 are still compressed, and the other two leaf springs 38 are still extended. With the continued rotation of the cam plate 27, the roller 29 and the first L-shaped plate 26 continue to move toward the fourth support 24, the first L-shaped plate 26 drives the rectangular insertion tube 32 to move toward the fourth support 24 via the second telescopic rod 30, and then the end of the corresponding second L-shaped plate 39 with the round corner 41 gradually disengages from the rectangular insertion tube 32 until the rectangular insertion tube 32 no longer limits the second L-shaped plate 39. Because the rectangular inserting cylinder 32 is no longer limited to the corresponding second L-shaped plate 39, the rotation of the second rotating shaft 19 is no longer limited, so that the first swinging plate 35 can drive the second rotating shaft 19 to rotate through the fixed block 36, the plate spring 38 and the second swinging plate 37, the second rotating shaft 19 drives the second L-shaped plate 39 to rotate, one end of the second L-shaped plate 39 on the corresponding side of the rectangular inserting cylinder 32, which is provided with the round angle 41, can be in frictional contact with the side surface of the rectangular inserting cylinder 32, and the frictional resistance of one end of the second L-shaped plate 39, which is provided with the round angle 41, to the rectangular inserting cylinder 32 cannot greatly influence the movement of the rectangular inserting cylinder 32 to the fourth support 24. With the continued rotation of the cam plate 27 until the rotation angle is 60 degrees, in this state, the roller 29 is in pressing contact with the end of the cam plate 27, away from the rotating sleeve 21, of the corresponding cam 42, the roller 29 and the first L-shaped plate 26 move to the maximum in the direction of the fourth support 24, the first spring 28 and the first telescopic rod 25 are compressed to the maximum, and the rectangular insertion tube 32 moves to the direction of the fourth support 24, so that the rectangular insertion tube 32 is located outside the outer circumferential surface of the second rotating shaft 19, and thus all the second L-shaped plates 39 on the second rotating shaft 19 do not interfere with the rectangular insertion tube 32 when rotating along with the second rotating shaft 19. After the rotation of the rotary sleeve 21 is finished by 60 degrees, the first swing plate 35 can drive the second rotating shaft 19 to rotate by 60 degrees through the fixed block 36, the plate spring 38 and the second swing plate 37, and all the plate springs 38 finally return to the natural state. The second rotating shaft 19 drives the triangular prism 4 to rotate by 60 degrees, and the connecting shaft 5 rotates by 60 degrees along with the triangular prism 4; after the triangular prism 4 rotates by 60 degrees, one end of the triangular prism 4 far away from the vertical fixing plate 2 is a sharp corner of the triangular prism 4. The servo motor 7 drives the driving shaft 8 to rotate for one circle again, the process is repeated, the triangular prism 4 rotates for 60 degrees again, the triangular prism 4 can rotate for 120 degrees in an accumulated mode, and finally after all the triangular prisms 4 rotate for 120 degrees, one side face, far away from the vertical fixing plate 2, of all the triangular prisms 4 is switched into the next group of advertisements. In the process that the servo motor 7 drives the driving shaft 8 to rotate for one turn again, the cam disc 27 also rotates for 60 degrees again; during the process of rotating the cam plate 27 for 60 degrees again, the roller 29 rolls gradually from the end of the corresponding cam 42 far away from the rotating sleeve 21 in the cam plate 27 to the concave position between two adjacent cams 42 in the cam plate 27, under the reset action of the first spring 28 and the second spring 31, the roller 29 is ensured to be always in pressing contact with the outer disc surface of the cam plate 27, the first L-shaped plate 26 drives the rectangular insertion barrel 32 to move and reset through the second telescopic rod 30, the end of the corresponding second L-shaped plate 39 with the round corner 41 is reinserted into the rectangular insertion barrel 32, the second telescopic rod 30 and the second spring 31 are compressed again, and the barrel mouth of the rectangular insertion barrel 32 is in pressing contact with the baffle 40 on the second L-shaped plate 39.

When the three-face turning billboard is in a group of advertising propaganda state and the external wind speed reaches a high wind level, in order to increase the wind resistance of the three-face turning billboard, the invention can automatically carry out the following operations: when the wind speed sensor identifies that the external wind speed is higher than the strong wind, the wind speed sensor transmits the identified external wind speed signal to the PLC control system, the PLC control system analyzes the signal and then controls the servo motor 7 to drive the driving shaft 8 to rotate for one circle, and the PLC control system controls the servo motor 7 not to rotate any more. According to the result that the servo motor 7 drives the driving shaft 8 to rotate for one circle, all the triangular prisms 4 turn over for 60 degrees, and the ends, far away from the vertical fixing plate 2, of the triangular prisms 4 are sharp corners of the triangular prisms 4, so that the side faces of the triangular prisms 4 are switched from the front windward side to the sharp corners of the triangular prisms 4 to carry out the front windward side; compared with the side face of the triangular prism 4 facing the wind in the front direction, the sharp corner of the triangular prism 4 facing the wind in the front direction has the advantages that the front wind can be shunted according to the known sharp corner of the triangular prism 4, so that the wind power received by the triangular prism 4 is weakened to a certain extent, the wind resistance of the triangular prism 4 is enhanced to a certain extent, the wind resistance of the three-face turning billboard is further increased to a certain extent, and the damage of strong wind to the three-face turning billboard is weakened to a certain extent. Under the strong wind condition, because servo motor 7 drives drive shaft 8 and no longer rotates after the round of rotation, as shown in fig. 6, then servo motor 7 drives drive shaft 8 and the corresponding extrados of sheave 16 in the geneva gear 12 after the round of rotation and notch dish 14 are laminated mutually, according to the theory of operation of geneva gear 12, notch dish 14 carries on spacingly to sheave 16 this moment, and then first gear 10 and second gear 20 all can not rotate, thereby trilateral turn-over mechanism also can not overturn the 60 degrees automatically and switch under the strong wind effect, guaranteed that the closed angle of triangular prism 4 can be in the state of positive windward continuously. When strong wind continuously blows the sharp corner of the triangular prism 4, due to the design of the plate spring 38, the triangular prism 4 can drive the second rotating shaft 19 to rotate in a small amplitude under the action of the strong wind, so that the triangular prism 4 can automatically turn in a small amplitude for a certain angle under the action of the strong wind; the design of the plate spring 38 can enable the sharp angle of the triangular prism 4 to be automatically adjusted in a small range according to the wind direction of strong wind, so that the sharp angle of the triangular prism 4 can better face the wind.

When the external wind speed is lower than the high wind level and the wind speed sensor identifies that the external wind speed is lower than the high wind level, the wind speed sensor transmits the identified external wind speed signal to the PLC control system, and the PLC control system analyzes the signal and then controls the servo motor 7 to drive the driving shaft 8 to rotate for one circle at the normal gap frequency.

When a set of advertisement has been constituteed to a side of keeping away from vertical fixed plate 2 of triangular prism 4, under this state, there is the benefit of the design requirement of less interval between two adjacent triangular prisms 4 to lie in: when the foreign matter is blown to the interval between two triangular prisms 4 and blocks two triangular prisms 4 by external wind, two triangular prisms 4 will not easily overturn, but because of the design of plate spring 38, when two triangular prisms 4 overturn simultaneously, the overturn of one of the triangular prisms 4 can lag behind the overturn of the other triangular prism 4, so the foreign matter will not easily clamp two triangular prisms 4, which is helpful for smooth overturn switching advertisement of the triangular prisms 4.

Because three second L type boards 39 circumference evenly distributed, rectangular section of thick bamboo 32 is inserted along the axis linear motion of second telescopic link 30, so when each second L type board 39 had the one end of fillet 41 and inserted rectangular section of thick bamboo 32, the rotation 120 degrees that second pivot 19 can be accurate, has guaranteed the precision that triangular prism 4 switched the advertisement. However, when the three-face turning mechanism is turned for a long time, the second rotating shaft 19 rotates 120 degrees and has a small angle error due to mechanical abrasion or mechanical accumulated transmission errors of some structures in the three-face turning mechanism; in order to ensure that the second rotating shaft 19 can still accurately rotate 120 degrees, the nozzle of the rectangular insertion tube 32 is a bell-mouth 34, and the bell-mouth 34 can allow the second rotating shaft 19 to drive the second L-shaped plate 39 to rotate by a small error; when the rectangular insertion cylinder 32 moves towards the direction far away from the first L-shaped plate 26, under the guidance of the bell mouth 34, one end, with the round angle 41, of the second L-shaped plate 39 with a small amplitude error can still be inserted into the rectangular insertion cylinder 32, and the end, with the round angle 41, of the second L-shaped plate 39 is inserted into the rectangular insertion cylinder 32, so that the second rotating shaft 19 can be ensured to rotate 120 degrees accurately, the overturning precision of the three-face overturning mechanism can be maintained during long-time overturning work, and the long-term use of the three-face overturning billboard is ensured.

For the design benefit that the first spring 28, the first telescopic rod 25, the second spring 31 and the second telescopic rod 30 are still in a compressed state when the roller 29 is located at the recess between two adjacent cams 42 in the cam plate 27: with the long-term friction wear of the roller 29 and the cam disc 27, the amount of the movement of the roller 29 pushed by the cam disc 27 along the axis of the first telescopic rod 25 is not accurate any more, so that the displacement of the rectangular insert cylinder 32 for limiting the position of the corresponding second L-shaped plate 39 is not accurate any more; however, due to the design requirements of the first spring 28, the first telescopic rod 25, the second spring 31 and the second telescopic rod 30, after the cam disc 27 is worn, the first spring 28, the first telescopic rod 25, the second spring 31 and the second telescopic rod 30 are mutually in transmission fit and then automatically adjusted to compensate the displacement of the rectangular insertion tube 32 when the rectangular insertion tube 32 limits the corresponding second L-shaped plate 39, so that the rectangular insertion tube 32 can still smoothly limit the corresponding second L-shaped plate 39, and the second rotating shaft 19 can be ensured to accurately rotate 120 degrees.

In the elastic bag 51 of the energy saving mechanism, when all the three-sided turning mechanisms do not perform the turning operation, all the elastic bags 51 are in a natural state.

For the action process of the energy-saving mechanism: when each three-face turning mechanism performs turning action, two adjacent three-face turning mechanisms are used for describing that the rotation directions of the second gears 20 in the two adjacent three-face turning mechanisms are opposite, so that the rotation directions of the first swing plates 35 in the two adjacent three-face turning mechanisms are opposite, the first swing plates 35 in the two adjacent three-face turning mechanisms drive the first extrusion plates 55 to rotate in opposite directions through the first plates 54, and the rotation directions of the second swing plates 37 in the two adjacent three-face turning mechanisms drive the second extrusion plates 53 to rotate in opposite directions through the second plates 52, so that one elastic bag 51 in the elastic bags 51 at the two adjacent three-face turning mechanisms is extruded, and the other elastic bag 51 is opened. Since all the compressed elastic bags 51 are connected to the hydraulic inlet of the hydraulic motor 57 through the respective hydraulic pipes 56, all the expanded elastic bags 51 are connected to the hydraulic outlet of the hydraulic motor 57 through the respective hydraulic pipes 56; when all the three-side turning mechanisms perform turning actions, all the hydraulic oil in the extruded elastic bags 51 flows into the corresponding stretched elastic bags 51 through the corresponding hydraulic pipes 56 and the hydraulic motors 57, so that the hydraulic motors 57 can drive the third rotating shafts 58 to rotate forwards; after all the three-face turning mechanisms are turned over and are stable, the first extrusion plate 55 and the second extrusion plate 53 are restored to the original state, the elastic bag 51 is also restored to the natural state, and then the hydraulic oil in the originally opened elastic bag 51 flows into the originally pressed elastic bag 51 through the corresponding hydraulic pipe 56 and the hydraulic motor 57, so that the hydraulic motor 57 can drive the third rotating shaft 58 to rotate reversely; the positive and negative rotation of the third shaft 58 causes the generator 59 to generate ac power. After the generator 59 transmits the generated alternating current to the electric processor 61 through the first lead 60, the electric processor 61 processes the alternating current into direct current suitable for charging the battery 63, and then the electric processor 61 transmits the direct current to the battery 63 through the second lead 62, and the battery 63 stores the direct current. When the vehicle is in the daytime, the energy-saving controller 65 is used as a switch of the lighting system, and the lighting system cannot illuminate under the control of the energy-saving controller 65; when the vehicle is at night, under the control of the energy-saving controller 65, the energy-saving controller 65 can preferentially transmit the current in the battery 63 to the lighting system, and the lighting system illuminates; when the power of the battery 63 is used up, the energy-saving controller 65 transmits the current input by the external lead 66 to the lighting system, and the lighting system continues to illuminate.

In conclusion, the invention has the main beneficial effects that: when the three-face turning mechanism switches advertisements through turning actions for a long time, mechanical abrasion or mechanical accumulated transmission errors can occur on some structures in the three-face turning mechanism; the design that the rectangular insertion cylinder is inserted and matched with the three second L-shaped plates ensures that the second rotating shaft can continuously and accurately rotate for 120 degrees, so that the three-face turning mechanism can maintain the turning precision during long-time turning work, and further the long-term use of the three-face turning billboard is ensured. When the three-face turning billboard is influenced by strong wind, the sharp corner of the triangular prism can be continuously in a front windward state through automatic adjustment, so that the wind force borne by the triangular prism is weakened to a certain extent, the wind resistance of the triangular prism is enhanced to a certain extent, the wind resistance of the three-face turning billboard is further increased to a certain extent, and the damage of the strong wind to the three-face turning billboard is weakened to a certain extent. When the three-face turning billboard is used for switching advertisements once, the energy-saving mechanism can automatically collect energy when the advertisements are switched and store the energy in the battery for use at night, so that the effect of saving external electric quantity can be achieved, and the purpose of saving energy is achieved. The invention has simple structure and better use effect.
