Description

Technical Field

[0001] This invention relates to the field of microgrid technology, specifically to a distributed power source for microgrids. Background Technology

[0002] A microgrid, also translated as microgrid, refers to a small-scale power generation and distribution system composed of distributed power sources, energy storage devices, energy conversion devices, loads, monitoring and protection devices, etc. Distributed power sources are located at the user end and connected to the power grid at a voltage level of 35kV and below, primarily for local consumption. These power sources include solar energy, natural gas, biomass energy, wind energy, hydropower, hydrogen energy, geothermal energy, ocean energy, resource-integrated power generation (including coal mine gas power generation), and energy storage. Distributed power source devices refer to small, modular, environmentally compatible, independent power sources with a power output ranging from several kilowatts to 50MW. These power sources are owned by the power sector, power users, or third parties to meet specific requirements of the power system and users, such as peak shaving, supplying power to remote users or commercial and residential areas, saving on transmission and transformation investment, and improving power supply reliability.

[0003] Microgrid distributed power sources often need to be built in outdoor areas with fewer people and require sufficient protection. Current distributed power sources generally prevent environmental interference by strengthening the body, but this still allows some animals to constantly disturb the power source, eventually causing damage to the body or affecting the operation of the power source around the body, which is not conducive to the implementation of microgrids. Summary of the Invention

[0004] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted in this invention is as follows:

[0006] A distributed power supply for a microgrid includes: a body assembly, a photovoltaic module, and a protective assembly; wherein, the body assembly includes a housing, a power supply unit disposed within the housing, telescopic legs mounted on the bottom of the housing, an audible and visual alarm mounted on the side of the housing, a vibration sensor mounted on the housing, a fixing plate fixed to the bottom end of the telescopic legs, a double-headed electric push rod mounted in the middle of the housing, and a limiting plate mounted on the bottom end of the double-headed electric push rod; the photovoltaic module is disposed on the housing, and the photovoltaic module includes a turntable embedded in the housing, a servo motor connected between the housing and the turntable, a mounting groove formed on the turntable, and a component hinged to the turntable and located within the mounting groove. The photovoltaic panel, a slide rail installed at the bottom of the photovoltaic panel, a slider mounted on the slide rail, an electric telescopic rod connected to the slider and hinged in the turntable, a spike set on the photovoltaic panel, and a photosensitive sensor installed on the photovoltaic panel; the protective assembly is set on the housing, and the protective assembly includes a side slot opened on the side of the housing, a rotating shaft assembled in the side slot, a spike rod connected to the bottom of the rotating shaft, an adjustment plate fixed to the inner side of the rotating shaft, a vertical plate mounted in the side slot and located inside the spike rod, an adjustment groove opened in the vertical plate for the adjustment plate to be placed, and a mounting base plate connected to the bottom of the vertical plate and connected to the other end of the double-headed electric push rod.

[0007] In a preferred embodiment, the present invention can be further configured such that: the driving end of the dual-headed electric actuator is hinged with a plug rod, and the bottom end of the plug rod is conical.

[0008] In a preferred embodiment, the present invention may be further configured such that: a buffer rod located between the insert rods is fixed on the drive end of the dual-headed electric push rod, and an insert block is provided on the outer end of the buffer rod.

[0009] In a preferred embodiment, the present invention may be further configured such that: the front of the housing is provided with a switch door located on the side of the power supply body, for maintenance and repair of the power supply body.

[0010] In a preferred embodiment, the present invention may be further configured such that another set of vibration sensors is mounted on the photovoltaic panel.

[0011] In a preferred embodiment, the present invention may be further configured such that a support frame for supporting the photovoltaic panel is installed inside the mounting groove.

[0012] In a preferred embodiment, the invention may be further configured such that the protrusions are disposed between the sheets on the photovoltaic panel.

[0013] In a preferred embodiment, the present invention can be further configured such that corresponding drainage holes are provided on the turntable and the housing.

[0014] The above-described technical solution of the present invention has the following beneficial technical effects:

[0015] 1. This invention, through its protective components, allows the connected vertical plate to move via a double-headed electric push rod. This, in turn, uses an adjustment groove to press down on the adjustment plate, making it vertical. Simultaneously, the spikes tilt upwards under the rotation of the shaft, thus protecting the casing and preventing animals from interfering with or damaging the equipment, significantly improving power supply safety.

[0016] 2. This invention utilizes photovoltaic modules to generate photovoltaic power after the photovoltaic panel is raised. Simultaneously, a servo motor, in conjunction with a photosensitive sensor, can continuously adjust the optimal angle of illumination on the photovoltaic panel to achieve the best photovoltaic power generation scenario. Furthermore, the spikes on the photovoltaic panel can provide protection, preventing various animals from lingering on it, which is quite reasonable.

[0017] 3. Through the body components, the present invention can be fixed to the ground by the structure connected at the bottom of the double-headed electric push rod, which improves the stability of the power supply. When the double-headed electric push rod drives the insertion rod to continuously enter the ground, the downward pressure exceeds the maximum force of the buffer rod. The buffer rod will slowly retract, causing the insertion block to enter between the insertion rods and separate them. The insertion rods are inserted into the ground in a petal shape, which improves the stability of the double-headed electric push rod on the machine casing. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0027] The following describes, with reference to the accompanying drawings, some embodiments of a microgrid distributed power source provided by the present invention.

[0028] Example 1:

[0029] Combination Figures 1-4 As shown, the present invention provides a microgrid distributed power source, comprising: a body component 100, a photovoltaic module 200, and a protection component 300;

[0030] The body assembly 100 includes a housing 110, a power supply unit 120 disposed within the housing 110, a telescopic leg 130 mounted on the bottom of the housing 110, an audible and visual alarm 140 mounted on the side of the housing 110, a vibration sensor 150 mounted on the housing 110, a fixing plate 160 fixed to the bottom of the telescopic leg 130, a double-headed electric push rod 170 mounted in the middle of the housing 110, and a limiting plate 180 mounted at the bottom of the double-headed electric push rod 170. The body assembly 100 is connected via the body assembly. The component 100 can be fixed to the ground using the structure connected to the bottom of the dual-headed electric push rod 170, which improves the stability of the power supply. When the dual-headed electric push rod 170 drives the insertion rod 171 to continuously enter the ground, the downward pressure exceeds the maximum force of the buffer rod 172. The buffer rod 172 will slowly retract, causing the insertion block 173 to enter between the insertion rods 171 and separate the insertion rods 171. The insertion rods 171 are inserted into the ground in a petal shape, which improves the stability of the dual-headed electric push rod 170 on the housing 110.

[0031] Specifically, the drive end of the dual-headed electric push rod 170 is hinged with a plug rod 171, and the bottom end of the plug rod 171 is conical. A buffer rod 172 located between the plug rods 171 is also fixed on the drive end of the dual-headed electric push rod 170. The outer end of the buffer rod 172 is also provided with a plug block 173. The plug rod 171 has a multi-lobed structure and is used to insert into the ground. When the plug rod 171 is spread out and fixed in the ground, the stability is higher. The dual-headed electric push rod 170 supports the housing 110, while the telescopic leg 130 limits the housing 110 and is fixed to the ground by the fixing plate 160.

[0032] Furthermore, the front of the housing 110 is provided with a switch door located on the side of the power supply body 120 for maintenance and repair of the power supply body 120.

[0033] The photovoltaic module 200 is mounted on the housing 110 and includes a turntable 210 embedded in the housing 110, a servo motor 220 connecting the housing 110 and the turntable 210, a mounting groove 230 formed in the turntable 210, a photovoltaic panel 240 hinged to the turntable 210 and located in the mounting groove 230, a slide rail 250 mounted on the bottom of the photovoltaic panel 240, a slider 260 clamped on the slide rail 250, and an electric motor connected to the slider 260 and hinged to the turntable 210. The telescopic pole 270, the spikes 280 mounted on the photovoltaic panel 240, and the photosensitive sensor 290 mounted on the photovoltaic panel 240 enable photovoltaic power generation after the photovoltaic panel 240 is raised via the photovoltaic module 200. At the same time, the servo motor 220, in conjunction with the photosensitive sensor 290, can continuously adjust the optimal angle of illumination on the photovoltaic panel 240 to achieve the best photovoltaic power generation scenario. Meanwhile, the spikes 280 on the photovoltaic panel 240 can also provide protection for the photovoltaic panel 240, preventing various animals from lingering on it, which is quite reasonable.

[0034] Furthermore, a support frame 231 for supporting the photovoltaic panel 240 is installed inside the mounting groove 230. The support frame 231 can support the photovoltaic panel 240 and improve its stability. In addition, corresponding drainage holes are provided on the turntable 210 and the housing 110 to drain the water accumulated on the mounting groove 230 and the housing 110. The protrusions 280 are set between the panels on the photovoltaic panel 240. The protrusions 280 can protect the photovoltaic panel 240 without affecting its operation, which is quite reasonable.

[0035] The protective component 300 is disposed on the housing 110. The protective component 300 includes a side slot 310 formed on the side of the housing 110, a rotating shaft 320 assembled in the side slot 310, a spike 330 connected to the bottom of the rotating shaft 320, an adjusting plate 340 fixed to the inner side of the rotating shaft 320, a vertical plate 350 clamped in the side slot 310 and located inside the spike 330, an adjusting groove 360 ​​formed in the vertical plate 350 for placing the adjusting plate 340, and a groove connected to the vertical plate 350. The mounting base plate 370, which is at the bottom of 350 and connected to the other end of the double-headed electric push rod 170, can move the connected vertical plate 350 through the protective component 300 via the double-headed electric push rod 170. Then, the adjusting plate 340 is pressed down by the adjusting groove 360, so that the adjusting plate 340 becomes vertical. At the same time, the spike rod 330 is tilted up by the rotation of the rotating shaft 320, thus completing the protection of the housing 110, preventing animals from interfering with or damaging the equipment, and greatly improving the safety of the power supply.

[0036] Specifically, the protective components 300 are disposed on multiple surfaces of the housing 110, and multiple sets of spikes 330 are arranged vertically side by side, which can provide multi-directional protection for the housing 110. When an animal comes into contact with the spikes 330, it will cause injury, thereby solving the problem of animal repellency.

[0037] Example 2:

[0038] Combination Figure 2 As shown, based on Embodiment 1, another set of vibration sensors 150 is installed on the photovoltaic panel 240. The vibration sensors 150 can detect the vibration of the surrounding structure. When the vibration exceeds the warning value, the sound and light alarm 140 is activated, the protective component 300 is also activated, and the photovoltaic module 200 is reset to perform self-protection.

[0039] The working principle and usage process of this invention are as follows: First, move the equipment to the designated location and use the telescopic legs 130 for basic support. Then, drive the insertion rod 171 into the ground via the double-headed electric push rod 170 until the insertion block 173 experiences pressure exceeding the force range of the buffer rod 172. At this point, the buffer rod 172 retracts, and the insertion block 173 enters between the insertion rods 171, pushing the insertion rods 171 outwards and causing them to enter the ground laterally. Then, rotate the driving end of the double-headed electric push rod 170 to adjust the position of the limiting plate 180, so that the limiting plate 180 is in contact with the ground. Finally, lock the telescopic legs 130. Then, the fixing plate 160 is fixed to the ground with the ground nails to complete the installation. When in use, the electric telescopic rod 270 lifts the photovoltaic panel 240, and the servo motor 220 drives the turntable 210 to rotate. With the help of the photosensitive sensor 290, the photovoltaic panel 240 is always in the best position and angle of illumination. When the vibration sensor 150 detects vibration, the double-headed electric push rod 170 drives the vertical plate 350 connected to the mounting base plate 370 to move downward. At this time, under the action of the adjustment groove 360, the adjustment plate 340 is pushed, causing the spike 330 to be raised for protection. At the same time, the photovoltaic module 200 is retracted into the housing 110.

[0040] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
