Description

Technical Field

[0001] This invention belongs to the field of power engineering technology, specifically an integrated switching device for source-grid-load-storage systems. Background Technology

[0002] With the rapid development of the new energy industry, the integrated source-grid-load-storage technology has become a key means to achieve multi-energy complementarity and ensure the stable operation of the power system. Among them, the intelligent switching device, as the core control unit of the source-grid-load-storage system, is responsible for coordinating the dynamic matching of energy production (source), transmission and distribution network (grid), load consumption (load) and energy storage regulation (storage). Its performance directly affects the safety and economy of the system.

[0003] A search revealed that CN216904724U discloses an integrated intelligent switching device for power generation, grid, load, and storage. This device, by setting up a main controller, a multi-channel switching module, and a status monitoring unit, enables rapid switching between new energy power generation units such as photovoltaic and wind power, energy storage systems, and loads. Under conditions such as grid faults and sudden load changes, it can complete grid-connected and off-grid mode conversion, energy storage charging and discharging strategy adjustment, and load priority scheduling through preset logic, effectively improving the system's response speed and coordination efficiency.

[0004] While the aforementioned devices improve energy storage efficiency and energy utilization by switching between wind and photovoltaic power generation, they rely on intermittent renewable energy sources like photovoltaic and wind power, making them significantly susceptible to natural conditions. The switching device alone cannot completely offset these fluctuations, necessitating the introduction of a more stable base load power source as a supplement. In existing technologies, geothermal power generation, as a stable and renewable energy source, possesses natural advantages in multi-energy complementary systems. However, the operational stability of its core equipment, such as steam engines and geothermal water filters, still needs improvement. Traditional geothermal water filter bases are prone to loosening at connections and equipment displacement due to long-term high-frequency vibration, affecting normal filtration and subsequent power generation. This limits the integration and adaptation of geothermal power generation with existing source-grid-load-storage systems, resulting in its limited use in such systems. Therefore, to address these issues, an integrated switching device for source-grid-load-storage systems is proposed. Summary of the Invention

This invention, through the combination of a cleaning brush and a spray nozzle, allows a motor to drive the cleaning brush to move back and forth laterally. Simultaneously, the water spray pipe moves synchronously, creating pressure on the water inside the water storage pipe. This causes the water to be sprayed from the spray nozzle onto the surface of the photovoltaic panel. Combined with the movement of the cleaning brush, dust and impurities are removed to prevent them from covering the surface of the photovoltaic panel and affecting the solar energy reception efficiency. Furthermore, it eliminates the need for manual cleaning by operators, reducing workload. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1 to 7 As shown, the present invention provides an integrated switching device for a source-grid-load-storage system, including a base 100, and further including: a geothermal water filtration module 101, the geothermal water filtration module 101 being fixed to the top outer wall of the base 100 by a support mechanism 200, a steam turbine 102 being fixedly connected to the outer wall of the base 100, a geothermal energy storage module 103 being fixedly connected to the outer wall of the base 100, a wind power generation module 104, a wind power energy storage module 105, and a photovoltaic energy storage module 108 being fixedly connected to the outer wall of the base 100, a base 107 being provided on the top outer wall of the base 100, a photovoltaic power generation module 106 being provided on the outer wall of the base 107, and a cleaning mechanism 300 being provided on the outer wall of the base 107; The support mechanism 200 includes a fixed rod 201, a rotating rod 203 is hinged to the inner wall of the fixed rod 201 through a support plate 202, a sliding rod 204 is rotatably connected to the inner wall of the rotating rod 203, and a slider 205 is slidably connected to the outer wall of the fixed rod 201. The cleaning mechanism 300 includes a bracket 3004, a motor 3001 is fixedly connected to the outer wall of the bracket 3004, a threaded rod 3002 is fixedly connected to the output shaft of the motor 3001, and a cleaning brush 3003 is slidably connected to the inner wall of the bracket 3004.

[0021] The above scheme employs the following: Wind power generation module 104 is a wind turbine that generates electricity from wind power, which can be stored in wind power storage module 105. Photovoltaic power generation module 106 is mounted on base 107 and its tilt angle can be adjusted using existing technologies such as cylinders to maximize the absorption of solar energy. The electricity generated by solar energy can be stored in photovoltaic storage module 108. Geothermal water filtration module 101 can be connected to a geothermal water delivery pipeline. After filtration, the extracted underground hot water impurities enter a steam turbine 102 to generate electricity from steam, which can be stored in geothermal storage module 103. The wind power storage module 105, photovoltaic storage module 108, and geothermal storage module 103 can be combined. During the day, priority is given to photovoltaic power generation, and excess electricity can be stored in the photovoltaic storage module. In module 108, the photovoltaic power generation module 106 is idle at night, while the wind power generation module 104 has a high output. The photovoltaic energy storage module 108 and the wind power energy storage module 105 can be used together to store wind power energy, avoiding insufficient capacity or efficiency loss when the wind power energy storage module operates alone. Geothermal power generation has a stable output and low energy storage requirements, so its energy storage module can make up for the insufficient capacity or response speed of wind power energy storage. If wind or photovoltaic power continues to operate at high capacity, the geothermal energy storage module 103 can be used to absorb the remaining energy and store electrical energy using its large capacity characteristics. When the output of photovoltaic or wind power drops sharply, the lithium battery energy storage is immediately released to fill the gap, and the geothermal energy storage module 103 is activated at the same time to fill the long-term gap through stable output, avoid grid frequency fluctuations, and reduce energy storage losses caused by frequent charging and discharging due to wind and solar power fluctuations.

[0022] The support mechanism 200 also includes a connector 208, which is fixedly connected to the outer wall of the slider 205. The inner wall of the slider 205 is elastically connected to the insert 207 via a connecting spring 206. The outer wall of the fixing rod 201 has a slot 209.

[0023] By adopting the above solution: the support mechanism 200 can improve the stability of the bottom of the geothermal water filtration module 101, and the support plate 202 increases the contact area with the ground, making the geothermal water filtration module 101 more stable during operation. It will not cause the connection to loosen or the device to shift due to long-term vibration, thus affecting normal filtration. After the geothermal water is filtered, the power generation efficiency can be improved, and impurities are also prevented from affecting subsequent equipment such as the steam turbine 102 and evaporator. The support mechanism 200 can be unfolded or retracted. When the device needs to be moved and the geothermal water filtration module 101 needs to be transported, its retraction can reduce the space occupied and facilitate transportation.

[0024] The fixed rod 201 is fixedly connected to the bottom outer wall of the geothermal water filtration module 101. One end of the support plate 202 is hinged to the inner wall of the fixed rod 201, and the other end of the support plate 202 is hinged to the outer wall of the rotating rod 203. One end of the connecting spring 206 is fixedly connected to the outer wall of the insert block 207, and the other end of the connecting spring 206 is fixedly connected to the inner wall of the slider 205. The insert block 207 is slidably connected to the inner wall of the slider 205. The sliding rod 204 is slidably connected to the inner wall of the fixed rod 201. The insert block 207 is engaged with the slot 209. The fixed rod 201 can be fixed to the top outer wall of the base 100 by bolts.

[0025] Using the above solution: the fixing rod 201 is installed on the base 100 to support the geothermal water filtration module 101. During transportation, the support mechanism 200... Figure 4 As shown, the support plate 202 and the rotating rod 203 are both housed inside the fixed rod 201 and are fixed by the insertion block 207 engaging with a set of slots 209 above. When it needs to be unfolded and fixed at a suitable location, the operator can pull the insertion block 207 to disengage it from the slot 209, compress the connecting spring 206, and release the limit between the slider 205 and the connecting piece 208, thus moving the slider 205 downwards. The fixed rod 201 has three sets, and the sliders 205 on the outer wall of each set of fixed rods 201 are connected by the connecting piece 208. Pulling the connecting piece 208 can simultaneously move multiple sets of sliders 205. 5. When the slider 205 moves downward, it will drive the sliding rod 204 to move downward in sync, causing the end of the rotating rod 203 connected to the sliding rod 204 to move downward. The other end of the rotating rod 203 will drive the top of the support plate 202 to flip downward until the support plate 202 is in contact with the ground. At this time, the insertion block 207 corresponds to the position of the slot 209 below. The spring force of the connecting spring 206 makes the insertion block 207 insert into the slot 209, which can fix the support mechanism 200 and keep the support plate 202 in contact with the ground, thereby increasing the contact area with the ground and increasing the stability of the geothermal water filtration module 101.

[0026] The bracket 3004 is fixedly connected to the top outer wall of the base 107, the threaded rod 3002 is rotatably connected to the inner wall of the base 107, and the cleaning brush 3003 is slidably connected to the inner wall of the base 107.

[0027] The above solution is adopted as follows: The photovoltaic power generation module 106 is a photovoltaic power generation panel. The tilt angle of the power generation panel can be adjusted according to the angle of sunlight. When the power generation panel is adjusted to a horizontal state, water can be sprayed on its surface by the cleaning brush 3003 and the nozzle 302 to reduce the dust coverage on its surface, increase the intensity of solar energy absorption, and thus improve the power generation efficiency. When the motor 3001 starts, it will drive the threaded rod 3002 to rotate. The threaded rod 3002 can drive the cleaning brush 3003 to move laterally inside the bracket 3004. Due to the self-locking property of the threaded rod 3002, the cleaning brush 3003 will remain in position and will not move when the motor 3001 stops running. During the movement, the internal drive module of the cleaning brush 3003 can drive it to rotate. The soft bristles contact the surface of the power generation panel to clean the dust and impurities on its surface. Furthermore, the forward and reverse rotation of the output shaft of the motor 3001 outside the bracket 3004 can make the cleaning brush 3003 move back and forth.

[0028] The cleaning mechanism 300 also includes a water spray pipe 301, a nozzle 302 fixedly connected to the outer wall of the water spray pipe 301, a telescopic hose 303 fixedly connected to the outer wall of the water spray pipe 301, a valve 309 provided on the inner wall of the telescopic hose 303, a fixing block 310 fixedly connected to the top outer wall of the base 107, a rotating wheel 305 rotatably connected to the inner wall of the fixing block 310, a pull rope 304 wound around the outer wall of the rotating wheel 305, a water storage pipe 308 fixedly connected to the top outer wall of the bracket 3004, a pressure plate 306 elastically connected to the inner wall of the water storage pipe 308 through a return spring 307, a water tank 311 fixedly connected to the outer wall of the base 107, the water tank 311 being connected to the water storage pipe 308 through a water outlet pipe 312, and a one-way valve 313 fixedly connected to the inner wall of the water outlet pipe 312.

[0029] The above solution works as follows: When the cleaning brush 3003 moves laterally back and forth, it drives the water spray pipe 301 and the nozzle 302 to move synchronously. When the cleaning brush 3003 moves towards the motor 3001, the nozzle 302 sprays water onto the surface of the photovoltaic panel, improving the cleaning effect of the cleaning brush 3003. When the cleaning brush 3003 moves towards the water tank 311, it automatically replenishes water into the water storage pipe 308. Therefore, manual spraying and cleaning by operators is unnecessary, and the cleaning operation can be completed automatically, reducing workload. Water tank 311... Located diagonally above the water storage pipe 308, the water inside can flow downward into the water storage pipe 308 through the water outlet pipe 312 and the one-way valve 313. The gravity of the water will cause the one-way valve 313 to open. Under normal conditions, the water in the water storage pipe 308 will not flow into the telescopic hose 303 and the spray pipe 301 due to the obstruction of the valve 309 inside the telescopic hose 303. In this state, due to the elastic force of the return spring 307, the pressure plate 306 is located on the left side of the water storage pipe 308, and the water is located between the pressure plate 306 and the inner wall of the right side of the water storage pipe 308.

[0030] The water spray pipe 301 is fixedly connected to the outer wall of the top of the cleaning brush 3003. The telescopic hose 303 is fixedly connected to the outer wall of the water storage pipe 308. The two ends of the pull rope 304 are fixedly connected to the outer walls of the pressure plate 306 and the water spray pipe 301, respectively. The pressure plate 306 is slidably connected to the inner wall of the water storage pipe 308. One end of the return spring 307 is fixedly connected to the outer wall of the pressure plate 306, and the other end of the return spring 307 is fixedly connected to the inner wall of the water storage pipe 308. The two ends of the water outlet pipe 312 are fixedly connected to the outer walls of the water tank 311 and the water storage pipe 308, respectively. The pull rope 304 passes through the outer wall of the water storage pipe 308.

[0031] The above solution is adopted: such as Figure 5 and Figure 6As shown, when the cleaning brush 3003 moves towards the motor 3001, the water spray pipe 301 moves synchronously, driving the pull rope 304 to move synchronously with its fixed end. The pull rope 304 is a stainless steel wire rope, which has no risk of rust when immersed in water, has high strength and is relatively flexible. The pull rope 304 moves along the outer wall of the rotating wheel 305, causing the rotating wheel 305 to rotate and reducing friction. Its other end pulls the pressure plate 306 to move, generating a pushing force on the water in the water storage pipe 308 and stretching the return spring 307. The water moves towards the water tank 311. Affected by the one-way valve 313, it will not flow back into the water tank 311 through the outlet pipe 312, but will be pushed open by the high pressure of the valve 309 and flow to the extension. The flexible hose 303 and the spray pipe 301 are connected, and the water is sprayed from the nozzle 302 onto the surface of the photovoltaic panel under pressure. When the spray pipe 301 moves, the flexible hose 303 will stretch and bend, and the cleaning brush 3003 will achieve a cleaning effect by rotating. When the cleaning brush 3003 moves to the water tank 311 to reset, the reset spring 307 pulls the pressure plate 306 to reset, the water in the storage pipe 308 loses pressure, the nozzle 302 stops spraying water, and the water in the water tank 311 will flow through the outlet pipe 312 and the one-way valve 313 to the storage pipe 308 for replenishment, in preparation for the next side to be sprayed for cleaning. The cleaning operation can be completed by repeating the above process by the reciprocating movement of the cleaning brush 3003.

[0032] Working principle and usage process of this invention: After the device is started, the photovoltaic power generation module 106 absorbs light energy and supplies the generated electricity to users first, with the excess stored in the photovoltaic energy storage module 108; the wind power generation module 104 generates electricity using wind energy, and the electricity is stored in the wind power energy storage module 105; the geothermal water enters the steam turbine 102 after being filtered by the geothermal water filtration module 101, generates electricity through steam, and the electricity is stored in the geothermal energy storage module 103.

[0033] During the day, photovoltaic power generation is prioritized, and photovoltaic energy storage module 108 stores surplus electricity. At night, when photovoltaic power generation module 106 is idle, wind power generation module 104 provides the main power supply, and photovoltaic energy storage module 108 and wind power energy storage module 105 work together to store electricity. Geothermal energy storage module 103, due to its stable output, can make up for insufficient wind power or photovoltaic energy storage capacity, or release electricity when wind and solar power output drops sharply, serving as a backup to maintain grid stability.

[0034] During the installation of the geothermal water filtration module 101, the operator can fix the fixing rod 201 to the base 100 with bolts, then pull the insert 207 to disengage it from the slot 209, move the connector 208 downwards, and the slider 205 will drive the sliding rod 204 and the rotating rod 203 to move downwards, causing the support plate 202 to flip outwards and fit against the ground; the insert 207 moves down with the slider 205 to the lower slot 209 position, and is snapped into the slot by the elastic force of the connecting spring 206, fixing the support plate 202, increasing the contact area between the bottom of the fixing rod 201 and the base 100, thereby enhancing the stability of the geothermal water filtration module 101, avoiding long-term vibration during operation that could cause the connection to loosen or the device to shift, making it more stable.

[0035] After prolonged use, a large amount of dust and impurities will accumulate on the surface of the photovoltaic power generation module 106, affecting the efficiency of light energy reception. At this time, the operator can adjust the photovoltaic power generation module 106 to a horizontal position, start the motor 3001, drive the threaded rod 3002 to rotate, and drive the cleaning brush 3003 to move to the side of the motor 3001. The water spray pipe 301 moves with the cleaning brush 3003, and pulls the pressure plate 306 through the pull rope 304, which generates pressure on the water in the water storage pipe 308, causing the water to push open the valve 309 and enter the water spray pipe 301 through the telescopic hose 303, and spray out from the nozzle 302 onto the surface of the photovoltaic panel. When the cleaning brush 3003 moves, the internal drive module rotates, and the soft bristles cooperate with the water flow to clean the dust on the surface of the photovoltaic panel.

[0036] After one cleaning cycle, the motor 3001 reverses, the cleaning brush 3003 moves in the opposite direction, the reset spring 307 pulls the pressure plate 306 back to its original position, the pressure in the water storage pipe 308 disappears, the valve 309 closes, and the water tank 311 replenishes water to the water storage pipe 308 through the water outlet pipe 312, preparing for the next cleaning cycle. The forward and reverse rotation of the motor 3001 enables the cleaning brush 3003 to move back and forth, completing the comprehensive cleaning of the photovoltaic panel without requiring manual cleaning by the operator, thus reducing workload.
