Description

[0001] The present disclosure relates to the field of solar street lamps, and more particularly, to a solar lamp pole. Background Art

[0002] Solar street lights use solar energy as the main energy source, supplemented by wind power generation, and are connected to the public power grid to send their excess electricity to the grid, and draw electricity from the grid when their own power generation is insufficient. This type of street light can be used for lighting in towns, squares, schools, parks, streets, and lawns.

[0003] At present, traditional solar street light poles mostly use fixed solar panels, which are usually installed at an optimized tilt angle (usually 26°). After the fixed solar photovoltaic components are installed, the position and orientation of the panels are fixed. At different longitudes and latitudes, the different trajectories of the sun cause great differences in the absorption of solar radiation energy. In order to maximize the conversion of light energy into electrical energy, the technology that uses control methods to achieve the maximum power operation of photovoltaic cells is called MPPT (Maximum Power Point Tracking (MPPT) technology). Generally, a DC electric push rod is used to drive the solar panel to adjust the angle to improve the photoelectric conversion output. However, the application scenarios of DC electric push rods are generally simple, and they are mostly used in electric doors and windows, access control systems, nursing beds and other scenarios. The stroke of the push rod needs to be manually controlled. It has output torque and is suitable for single-direction opening. However, the failure rate is high when used outdoors, and regular maintenance is required. Multiple linkage cannot be achieved, and it is difficult to make the angle between the solar panel and the sunlight an optimized tilt angle to obtain the maximum photoelectric conversion output.

It should also be understood that terms defined in general dictionaries should be interpreted as having meanings consistent with their meanings in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined herein.

[0026] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0027] In an embodiment of the present invention, a solar lamp pole 1 is disclosed, comprising: a lamp pole 1; a lamp holder 2, which is fixed on the lamp pole 1 for supporting the lamp; a motor support rod 3, which is fixed on the lamp pole 1 and extends laterally; a triangular motor support seat 4, the middle of which is fixed to the lateral outer end of the motor support rod 3, and the motor support seat 4 includes three vertices and a connecting rod 41 connecting adjacent vertices to each other; a solar panel 5, and three ball sockets 51 are opened on the solar panel 5. The lamp pole 1 is used to fix and support the lamp holder 2, and the lamp holder 2 is located at the top of the lamp pole 1; one end of the motor support rod 3 is fixedly connected to the lamp holder 2, and the other end of the motor support rod 3 is fixedly connected to the motor support seat 4. The shape of the motor support seat 4 can be triangular. The triangle has stability, which is conducive to strengthening the stability of the structure. The motor support seat 4 is composed of three connecting rods 41, and the adjacent vertices of the connecting rods 41 are connected to each other.

[0028] Further, for the three programmable linear motors 6, each programmable linear motor 6 is fixed and supported on each vertex of the motor support seat 4, and a protruding rod 61 is connected to the distal side of the main shaft, and a spherical member 63 is formed at the distal end of each protruding rod 61, which is used to be received in a corresponding ball socket 51 on the solar panel 5 in a pivotable manner. Each programmable linear motor 6 advances or retracts the main shaft in response to the azimuth adjustment instruction of the solar panel 5, and then advances or retracts the protruding rod 61 to adjust the azimuth of the solar panel 5. By allowing three programmable linear motors 6 to be respectively arranged at the positions of the three vertices of the motor support seat 4, and the programmable linear motor 6 is connected to one end of the extension rod 61, and the other end of the extension rod 61 is rotatably connected to the ball socket 51 on the solar panel 5, the portion of the extension rod 61 inserted into the ball socket 51 can rotate relative to the inner wall of the ball socket 51, and at the same time, when the angle between the solar panel 5 and the extension rod 61 changes, the portion of the extension rod 61 inserted into the ball socket 51 rotates with the ball socket 51 to adjust and change the angle between the extension rod 61 and the solar panel 5, and the extension rod 61 can fix and support the solar panel 5. When each programmable linear motor 6 receives the azimuth adjustment instruction of the solar panel 5, it moves in a straight line, advances or retracts on the main axis, and the programmable linear motor 6 drives the extension rod 61 to move when moving, and adjusts the extension or retraction length of the extension rod 61. When one of the three programmable linear motors 6 receives the azimuth adjustment instruction of the solar panel 5 and performs linear motion to advance or retract the main shaft to adjust the extension or retraction length of the extension rod 61, since the positions of three points in space can determine a plane, the extension rod 61 inserted into the ball socket 51 and the part with the ball socket 51 can be regarded as a point supporting the solar panel 5. When the position of one of the points is changed, the azimuth of the plane where the solar panel 5 is located can be adjusted, so that the angle between the solar panel 5 and the sunlight is kept at the optimized inclination angle (usually 26°) to obtain the maximum photoelectric conversion output. At the same time, the extension rod 61 is driven to move by the programmable linear motor 6. The method of driving the solar panel 5 to adjust its azimuth is conducive to reducing the failure rate of outdoor use, does not require frequent maintenance, and has a more reliable structure; by sending an azimuth adjustment instruction of the solar panel 5 to each programmable linear motor 6, the azimuth of the solar panel 5 can be automatically adjusted, so that the angle between the solar panel 5 and the sunlight is adjusted to maintain an optimized inclination angle (usually 26°) to obtain the maximum photoelectric conversion output; at the same time, the same azimuth adjustment instruction of the solar panel 5 can also be sent to each programmable linear motor 6 on multiple groups of lamp poles 1 in an area, so that the solar panel 5 can adjust its azimuth at the same time, realizing multi-unit linkage adjustment and more convenient control.

[0029] Furthermore, each vertex is formed into a spherical portion, and the spherical portion and the connected connecting rod 41 are fixedly connected or integrally formed with pre-tension. The three vertices of the motor support seat 4 are formed into a spherical portion, and the connecting rods 41 connected to each other by adjacent vertices of the three connecting rods 41 form the motor support seat 4. The shape of the motor support seat 4 can be triangular. The triangle has stability, which is conducive to strengthening the stability of the structure of the motor support seat 4. The spherical structure of the spherical portion reduces wind resistance, and the cross bar and the spherical member 63 are welded with tension to resist destructive environmental forces and extend the service life of the device. Through such an arrangement, it is easier to use the lower vertex as a fulcrum to flexibly adjust the extension rods 6 at the two upper vertices (part of the gravity can be used), thereby suppressing the deterioration caused by the tension on the solar panel 5 during the adjustment process, and no regular maintenance is required. The angle between the solar panel 5 and the sunlight is adjusted to an optimized inclination angle to obtain the maximum photoelectric conversion output.

[0030] Furthermore, sleeves 64 are fixedly provided on each vertex, and the proximal section of each extension rod 61 and the main shaft of each connected programmable linear motor 6 are all accommodated in the sleeves 64. Sleeves 64 are fixedly provided on each vertex of the motor support base 4, and the programmable linear motor 6 and its main shaft are respectively arranged in the sleeves 64. The sleeves 64 can provide protection for the programmable linear motor 6 to prevent the programmable linear motor 6 from being directly exposed to the outside world, being exposed to wind, sun and rain, causing it to fail, or affecting its service life. When the programmable linear motor 6 receives the azimuth adjustment instruction of the solar panel 5, it performs linear motion on the main shaft, and the programmable linear motor 6 drives the extension rod 61 to move, and the extension rod 61 is slidably connected to the inner wall of the sleeve 64 port, and the extension rod 61 can be extended or contracted relative to the sleeve 64 port.

[0031] Furthermore, the outer surfaces of the proximal section of each extension rod 61 and the distal section of the main shaft are formed with threads (not shown), and the inner surface of the inner cavity of the sleeve 64 is formed with threads. The main shaft is advanced or retracted through the threads on the inner surface, thereby pushing the extension rod 61 to advance or retract through the threads on the inner surface. The screw connection can further ensure the accuracy of the extension rod 61 in the direction of the main shaft, while reducing vibration during the movement.

[0032] In some embodiments of the present disclosure, a main controller 7 is further included, the lamp pole 1 is hollow and its inner cavity is used to arrange the main controller 7, each spherical part and each connecting rod 41 are hollow, each programmable linear motor 6 has a local controller 62, and the main controller 7 is wired to each local controller 62 via wiring penetrating the inner cavity of the lamp pole 1 and the inner cavity of each spherical part and each connecting rod 41, so as to send the azimuth adjustment instruction of the solar panel 5 to each programmable linear motor 6. Thus, the exposure of wires in the environment is reduced, maintenance is convenient, and the effects of climate are resisted. The local controller 62 is arranged inside the spherical part, and the local controller 62 is respectively arranged corresponding to each programmable linear motor 6, and the programmable linear motor 6 is controlled by the corresponding local controller 62. The main controller 7 is arranged inside the lamp pole 1. The main controller 7 is used to send an azimuth adjustment instruction of the solar panel 5 to the local controller 62. After receiving the azimuth adjustment instruction of the solar panel 5, the local controller 62 drives the programmable linear motor 6 to perform linear motion on the main axis, and the programmable linear motor 6 drives the extension rod 61 to move. The extension rod 61 is slidably connected to the inner wall of the sleeve 64 port. The extension rod 61 can be extended or contracted relative to the sleeve 64 port. Since the positions of three points in space can determine a plane, the extension rod 61 inserted into the ball socket 51 and the part with the ball socket 51 can be regarded as a point supporting a solar panel 5. When the position of one of the points is changed, the azimuth of the plane where the solar panel 5 is located can be adjusted, so that the angle between the solar panel 5 and the sunlight is adjusted to maintain the optimized inclination angle (26°) to obtain the maximum photoelectric conversion output.

[0033] In some embodiments of the present disclosure, two of the three vertices are arranged above the remaining vertex. The three vertices of the motor support seat 4 are formed into a spherical portion, and the three connecting rods 41 connected to each other at adjacent vertices constitute the motor support seat 4, wherein two vertices are arranged above the remaining vertex. Through such an arrangement, it is easier to use the lower vertex as a fulcrum to flexibly adjust the extension rods 6 at the two upper vertices (part of the gravity can be used), thereby suppressing the tension effect on the solar panel 5 during the adjustment process.

[0034] Further, the three programmable linear motors 6 are configured to, in response to the azimuth adjustment instruction of the solar panel 5: the two programmable linear motors 6 supported at the two upper vertices respectively advance or retract their spindles while the programmable linear motor 6 supported at the lower vertex maintains the spindle feed amount, thereby adjusting the solar panel 5 to a first azimuth; after adjusting to the first azimuth, the spindles of the programmable linear motors 6 supported at the lower vertex advance or retract while the two programmable linear motors 6 supported at the two upper vertices maintain their spindle feed amounts, thereby adjusting the solar panel 5 to a second azimuth defined by the azimuth adjustment instruction of the solar panel 5. In other words, the adjustment to the second azimuth can be performed in two steps. When the main controller 7 sends an azimuth adjustment instruction for the solar panel 5 to the local controller 62, the two local controllers 62 supported at the two upper vertices receive the azimuth adjustment instruction for the solar panel 5, and drive the two programmable linear motors 6 supported at the two upper vertices to perform linear motion on the main shaft, and the programmable linear motor 6 drives the extension rod 61 to move, and the extension rod 61 is slidably connected to the inner wall of the sleeve 64 port. The extension rod 61 can be extended or contracted relative to the sleeve 64 port, and the main shaft feed amount of the programmable linear motor 6 is controlled at the same time. Since the positions of three points in space can determine a plane, the extension rod 61 can be inserted into the ball socket 51 and the part with the ball socket 51 can be regarded as a point supporting the solar panel 5. When the position of the two vertices above the solar panel 5 is changed and adjusted, the azimuth of the plane where the solar panel 5 is located is adjusted from the initial angle to the first azimuth, so that the solar panel 5 stands up or lies down relative to the ground; then, While the two upper vertices maintain the adjustment state of the corresponding extension rod 61, the local controller 62 at the vertex below the main controller 7 receives the azimuth adjustment instruction of the solar panel 5, drives the corresponding programmable linear motor 6 to perform linear motion on the main shaft, and the programmable linear motor 6 drives the extension rod 61 to move. The extension rod 61 is slidably connected to the inner wall of the sleeve 64 port. The extension rod 61 can be extended or contracted relative to the sleeve 64 port. At the same time, the spindle feed amount of the programmable linear motor 6 is controlled. When the position of the adjustment support at the vertex below the solar panel 5 is changed, the azimuth of the plane where the solar panel 5 is located is adjusted from the initial angle from the first azimuth to the second azimuth, and the azimuth of the solar panel 5 is supplemented. The adjustment of the azimuth of the solar panel 5 is more precise, and the angle between the solar panel 5 and the sunlight can be adjusted according to the azimuth of the sunlight to maintain the optimized inclination (26°) to obtain the maximum photoelectric conversion output.

[0035] Furthermore, the main controller 7 is configured to determine the target azimuth of the solar panel 5 according to the information related to the sun's position in the time and space where the solar lamp pole 1 is located, and issue an azimuth adjustment instruction for the solar panel 5 accordingly. The movement law of the sun relative to the earth: on the spring equinox and autumn equinox, the sun rises from the east, reaches the meridian at noon, and is due south, and then sets from the west, with the day and night periods being equally divided. On the summer solstice, the sun rises from the northeast, reaches the meridian at noon, and is due south, and then sets from the northwest. This day has the longest daytime period and the shortest nighttime period in a year, and noon is when the solar altitude angle is the largest. On the winter solstice, the sun rises from the southeast, reaches the meridian at noon, and is due south, and then sets from the southwest. This day has the shortest daytime period and the longest nighttime period in a year, and noon is when the solar altitude angle is the smallest. The angle between the solar radiation direction at noon and the initially set PV panel surface is 91.03 degrees from the summer solstice (the sun is at a higher angle, 23 degrees on the celestial sphere), and the angle between the solar radiation direction at noon and the initially set PV panel surface is 71.99 degrees from the autumnal equinox to the spring equinox, and the angle is 53.54 degrees from the winter solstice. For the solar panel 5, the incident angle of the sunlight on the panel surface is a determining factor in the energy efficiency of the photovoltaic system. For the fixed solar panel 5, the sunlight is obliquely shining on the solar panel 5 for most of the day.

[0036] Furthermore, only when the angle between sunlight and the solar panel is the optimized inclination angle for the current local sun position information (for example, but not limited to 26°) can the maximum photoelectric conversion output be obtained. The required optimized inclination angle will be different depending on the time and space (latitude and longitude and calendar time) where the solar lamp pole 1 is located.

[0037] By determining the target azimuth of the solar panel 5 according to the information related to the sun's position in the time and space where the solar lamp pole 1 is located, the main controller 7 is based on the current local sun's position information (the latitude and longitude information can be pre-set in the main controller 7 according to the installation location before leaving the factory). The main controller 7 can obtain the current date and time of the day by connecting to the integrated clock module, and can obtain the clock through the local clock module, that is, the GPS system, or access the Internet of Things card to obtain the current clock information from the data base station. Based on this, the main controller 7 sends an azimuth adjustment instruction for the solar panel 5 to the local controller 62. The local controller 62 receives the azimuth adjustment instruction for the solar panel 5 and drives the corresponding programmable linear motor 6 to perform linear motion on the main shaft. The programmable linear motor 6 drives the extension rod 61 to move. The extension rod 61 is slidably connected to the inner wall of the sleeve 64 port. The extension rod 61 can be extended or contracted relative to the sleeve 64 port. At the same time, the main shaft feed amount of the programmable linear motor 6 is controlled. When the position of the adjustment support at the vertex below the solar panel 5 is changed, the azimuth of the plane where the solar panel 5 is located is adjusted from the initial angle from the first azimuth to the second azimuth. According to the azimuth of the sunlight, the angle between the solar panel 5 and the sunlight can be adjusted to maintain the optimized inclination angle (26°) to obtain the maximum photoelectric conversion output.

[0038] Furthermore, a three-axis acceleration sensor 71 is included, which is configured to detect the three-axis acceleration components of the solar panel 5 for determining the current azimuth of the solar panel 5. After the three-axis acceleration components of the solar panel 5 are detected by the three-axis acceleration sensor 71 for determining the current azimuth of the solar panel 5, the current azimuth of the solar panel 5 is determined after the azimuth of the solar panel 5 is adjusted.

[0039] Furthermore, the main controller 7 is further configured to: obtain the current azimuth of the solar panel 5; and issue an azimuth adjustment instruction for the solar panel 5 according to the current azimuth and the target azimuth, so that the azimuth adjustment instruction for the solar panel 5 defines the operating parameters of the programmable linear motor 6, and the operating parameters include the spindle feed amount and the operating time. The operating parameters can be determined in various ways. For example, the corresponding relationship between the current azimuth and the target azimuth and the operating parameters of the programmable linear motor 6 can be simulated through physical modeling. For another example, the corresponding relationship between the current azimuth and the target azimuth and the operating parameters of the programmable linear motor 6 can be pre-tested and recorded, and the main controller 7 can be called to determine the operating parameters when necessary, and so on.

[0040] When the solar panel 5 is subsequently adjusted in azimuth, the main controller 7 calculates the angle of the azimuth that needs to be adjusted (target azimuth-current azimuth=angle of the azimuth that needs to be adjusted), and calculates the operating parameters of the programmable linear motor 6 according to the angle of the azimuth that needs to be adjusted), wherein the operating parameters include the spindle feed amount and the operation time. The main controller 7 sends the operating parameters including the azimuth adjustment instruction of the solar panel 5 to the local controller 62, and the local controller 62 controls the position of the programmable linear motor 6 on the spindle for linear motion according to the spindle feed amount and the operation time. The linear motor 6 drives the extension rod 61 to move, and the extension rod 61 is slidably connected to the inner wall of the sleeve 64 port. The extension rod 61 can extend or contract relative to the sleeve 64 port, and at the same time control the spindle feed amount of the programmable linear motor 6. The extension rod 61 is slidably connected to the inner wall of the sleeve 64 port. The extension rod 61 can extend or contract relative to the sleeve 64 port, and at the same time accurately control the spindle feed amount of the programmable linear motor 6, so as to facilitate the precise control of the azimuth angle of the solar cell panel 5, so that the angle between the solar cell panel 5 and the sunlight is the optimized inclination angle (26°), and the maximum photoelectric conversion output is obtained.
