Description

Technical Field

[0001] The present invention relates to the technical field of energy-saving equipment, and in particular to a photovoltaic smart street lamp system based on temperature difference self-powering. Background Art

[0002] With the continuous development of science and technology, urban construction has gradually increased, leading to an increase in energy consumption. In order to reduce energy consumption, some public facilities, such as some street lights, have been improved and set up as photovoltaic energy storage devices to further reduce energy consumption. At the same time, it is not limited to simple photovoltaic power supply. It is also possible to form a complementary power supply system with other new energy sources such as wind power to improve the stability and sustainability of energy supply. Nowadays, street lights can also be intelligently set. Intelligent energy-saving street lights can automatically adjust the brightness according to factors such as ambient light and traffic flow to achieve on-demand lighting. For example, the street lights in Qinhan New City, Xixian New District, automatically dim and "rest" in the middle of the night when there are few people and cars. When traffic increases in the early morning, they pause and "rest" until they are turned off after dawn.

[0003] Nowadays, due to regional differences, the ambient temperature in some special areas has a large gap. The temperature gap can be used to supply electricity using a temperature difference self-powered equipment structure. Today's temperature difference self-powered structure can only achieve a single collection of temperature. The structure used in winter cannot be used in summer, resulting in energy waste affecting the use of street lamps. Summary of the Invention

[0013] The present invention provides a photovoltaic smart streetlight system based on temperature difference self-powered energy, which has the following beneficial effects: In the present invention, a lamp holder assembly is installed on the top of the lamp pole, and then the bearing assembly fixes the photovoltaic assembly on the top of the lamp holder assembly. The photovoltaic assembly has all the power control, and the photovoltaic panel of the photovoltaic assembly has the ability to adjust in any angle and direction, so that the photovoltaic panel can supplement the power to a certain extent. An auxiliary assembly is rotatably installed at the position of the bearing assembly, a transmission assembly is installed at the outer end of the auxiliary assembly, and a heating assembly is installed at the inner end of the auxiliary assembly. The heating assembly and the auxiliary assembly are intertwined, so that when the auxiliary assembly rotates, the auxiliary assembly and the heating assembly rub against each other, so that the heating assembly is heated, and an inner cylinder assembly is installed on the inside of the heating assembly. The inner cylinder assembly is connected to an expansion pipe buried underground, so that the inner cylinder assembly is cooled through the underground. A thermoelectric generator is installed near the inner tube component of the heating component to realize the temperature difference self-energy supply of the thermoelectric generator. The outer end of the auxiliary component is connected with the transmission component to realize the driving of the auxiliary component by the transmission component, thereby allowing the transmission component to transmit the auxiliary component. In special circumstances, the external environment is too cold, and the underground temperature of the inner tube component conducted through the expansion tube rises, so that an opposite temperature difference is formed between the inner tube component and the heating component, which can also enable the thermoelectric generator to perform temperature difference self-energy supply. At this time, the transmission component slides down to the lower end of the auxiliary component, so that the transmission component will not transmit to the auxiliary component, and there is a certain friction between the auxiliary component and the heating component, so that the auxiliary component no longer rotates, and the rotating transmission component will clean up the debris in the auxiliary component.

[0014] In addition, a top ring is first set on the top of the control box, and a rotating frame is rotatably installed on the top ring to achieve the effect that the rotating frame can rotate on the top ring. The limit ring of the top ring is limited by bolts. After the bolts of the limit ring are tightened, the limit ring can fix the rotating frame, so that the rotating frame can maintain a stable position, and the photovoltaic panel on the rotating frame can be swung and adjusted, so that the photovoltaic panel can be easily adjusted to any position.

[0015] In addition, a vertical groove is directly provided on the outer end of the outer sleeve to facilitate the sliding of the transmission component and the engagement of the auxiliary component, and to facilitate the transmission of the auxiliary component to the transmission component. A ring groove structure is provided near the edge of the outer end of the outer sleeve, so that the outer sleeve can rotate and install the transmission component through the ring groove. The heat exchange plates of the outer sleeve are arranged in a staggered array, so that the heat exchange plates can increase the contact surface with the external air, thereby realizing the exchange effect of the auxiliary component as a whole with the external air. The chamfered structure of the heat exchange plate can enable the transmission component to better achieve the contact effect with the heat exchange plate when passing through the heat exchange plate.

[0016] In addition, the external frame is directly set into three groups, and the bottom of the three groups of external frames are connected by a ring frame, so that the external frame can be installed on the ring groove of the auxiliary component through the stable rotation of the ring frame, and the outer plate frame is set to be slidably installed on the external frame, and the outer plate frame with a magnetic block allows the sliding position of the outer plate frame on the external frame to be adjusted up and down, thereby achieving the fixation and separation between the auxiliary component and the transmission component. The outer plate frame is installed at the outer end of the external frame, and the four groups of rectangular frames on the outer plate frame are hingedly installed with a one-way plate, so that when the external airflow blows through, the one-way plate of the outer plate frame is pushed in one direction, allowing the auxiliary component to rotate in one direction, and the outer end of the outer plate frame can be further equipped with an expanded outer plate frame, so that the transmission component can increase the contact surface with the air, which is convenient for the rotation efficiency of the transmission component. When the transmission component rotates, the extension brush of the external frame directly penetrates into the heat exchange plate of the auxiliary component, so that the extension brush can clean the debris accumulated on the heat exchange plate when rotating, thereby ensuring the heat exchange function of the auxiliary component.

[0017] In addition, when the device is in use, the outer frame needs to be installed on the inner end of the auxiliary component. A top screw hole is set on the top of the outer frame so that the outer frame and the auxiliary component can be fixed to each other after the bolt is installed, so that the outer frame can rotate with the auxiliary component. The outer frame is arranged in a semicircular shape, which is convenient for the outer frame to be installed on the outer end of the inner frame. The contact part between the inner frame and the outer frame is set as a concave-convex ring structure, so that when the outer frame rotates, the concave-convex ring structure contacts and rubs with the inner frame, thereby increasing the overall heat effect. A thermoelectric generator is installed on the inner frame to realize the temperature difference self-power supply of the thermoelectric generator.

[0018] In addition, the underground water well has the effect of keeping warm in winter and cool in summer, so an expansion pipe is set at the bottom of the inner tube block, and the end extension part of the expansion pipe is buried underground to extract a certain temperature underground, and the inner groove cavity of the inner tube block is set to a spiral structure, which can increase the heat exchange between the inner tube assembly and the heating assembly through the inner groove cavity of the bolt, making it convenient for the temperature difference generator of the heating assembly to perform temperature difference self-powering.

The inner cylinder assembly 7 and the heating assembly 6 and other components are installed at the outer end of the bearing assembly 2; In a season when the outside is hot, the transmission component 5 outside the auxiliary component 4 is slid toward the upper end, and the transmission component 5 is fixed to the top of the auxiliary component 4 by magnetic force, so that the transmission component 5 drives the auxiliary component 4. The rotating auxiliary component 4 contacts and rubs the heating component 6, so that the heating component 6 generates a certain amount of heat. The inner end of the heating component 6 is installed with an inner cylinder component 7, and the expansion tube 703 of the inner cylinder component 7 is directly buried in the earth to extract the low temperature of the earth, so as to achieve the temperature difference self-energy supply effect for the thermoelectric generator 604. In severe cold weather, the outside air is cold, while the underground is hotter than the outside, so that the inner cylinder component 7 can provide high temperature. At this time, the transmission component 5 needs to be lowered to separate the transmission component 5 from the top of the auxiliary component 4. The contact position between the auxiliary component 4 and the heating component 6 has a certain friction, which causes the auxiliary component 4 to stop rotating. The structure of the auxiliary component 4 can contact the outside air, which can reduce the temperature of the heating component 6. At this time, the rotating transmission component 5 has a cleaning effect on the auxiliary component 4.
