Description

Technical Field

[0001] This invention relates to the field of power supply technology, specifically to a photovoltaic-diesel energy storage and charging power supply device. Background Technology

[0002] The power supply system is a system that generates and supplies electrical energy to electrical equipment, consisting of a power supply system and a power transmission and distribution system. It can be roughly divided into three types: TN, IT, and TT. Among them, the TN system is divided into three forms: TN-C, TN-S, and TN-CS. The power supply system must follow the principles of reliable power supply, convenient operation, safe and flexible operation, and economic rationality. The power supply sources can be divided into mine power supply systems, urban power supply systems, electric traction power supply systems, power supply system impedance, power supply system harmonics, aircraft electrical systems, etc. The general principles for determining the power supply system are: reliable power supply, convenient operation, safe and flexible operation, economic rationality, and the possibility of development. Diesel generator set (1) Power supply reliability: Power supply reliability refers to the reliability of the uninterrupted power supply of the power supply system. It should be guaranteed according to the load level. In the design, double accidents are not considered. Control cabinet (2) Convenient operation, safe and flexible operation: The wiring of the power supply system should ensure convenient operation and maintenance, safe and reliable operation and maintenance during normal operation and in the event of an accident. Therefore, wiring should be simplified, power supply layers and operating procedures should be reduced, and moisture-proof short-circuit devices should be used. (3) The wiring method should be as simple as possible under the premise of meeting production requirements and ensuring power supply quality, so as to reduce investment and operating costs and improve power supply safety. (4) It should have the possibility of development. The wiring method should ensure that it is convenient for future development and can adapt to the needs of phased construction.

[0003] Existing diesel generator sets are equipped with control cabinets to control the operation of the diesel generator set. However, since the diesel generator set is located indoors, the environment is sometimes humid, which can cause a lot of moisture to accumulate inside the control cabinet. Long-term moisture will reduce the lifespan of the electrical components inside the control cabinet. In addition, since short circuits cannot be prevented in advance, the electrical components inside the control cabinet will need to be replaced when a short circuit occurs, which can cause damage. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a photovoltaic-diesel energy storage and charging power supply device. This solves the problem that existing diesel generator sets are equipped with control cabinets to control the operation of the diesel generator set. However, since the diesel generator set is located indoors, the environment is sometimes humid, leading to a large amount of moisture inside the control cabinet. Prolonged moisture reduces the lifespan of the electrical components inside the control cabinet. Furthermore, because short circuits cannot be prevented in advance, the electrical components inside the control cabinet need to be replaced in the event of a short circuit, causing damage.

A strip-shaped through hole is fixedly opened on the surface of the first drive seat. A first sliding block is threadedly sleeved on the surface of the lead screw. A sleeve plate is fixedly connected to the surface of the first sliding block. A heating plate is fixedly sleeved on the opposite side of the sleeve plate, and a connecting plate is fixedly connected to the opposite side of the sleeve plate. A winding wheel is rotatably sleeved within the inner cavity of the first sliding block on the left side. A second sliding block is slidably sleeved within the inner cavity of the connecting plate. An infrared thermal sensing camera is fixedly sleeved on the surface of the second sliding block. Sliding grooves are symmetrically fixedly opened on the inner wall of the connecting plate. A slider is symmetrically fixedly connected to the surface of the second sliding block. A spring is fixedly connected to one end of the slider, and a steel wire rope is fixedly connected to the surface of the second sliding block.

[0009] Preferably, the servo motor is fixedly connected to the top of the diesel generator set, and the surface of the lead screw penetrates through the top of the diesel generator set and the control cabinet.

[0010] Preferably, the surface of the first sliding block matches the inner cavity of the first drive seat and the second drive seat, the winding wheel is threaded onto the surface of the left lead screw, and the winding wheel is located in the inner cavity of the left first sliding block.

[0011] Preferably, the opposite sides of the first drive seat and the lead screw are fixedly connected to the left and right inner walls of the control cabinet cavity.

[0012] Preferably, the slider is slidably sleeved in the inner cavity of the groove, and the surface of the second sliding block matches the inner cavity of the connecting plate.

[0013] Preferably, the spring is located in the inner cavity of the slide groove, and one end of the spring is fixedly connected to the inner wall of the slide groove.

[0014] Preferably, one end of the wire rope penetrates the inner wall of the heating plate and extends to one end of the heating plate.

[0015] Preferably, one end of the wire rope passes through the strip-shaped through hole and the inner cavity and surface of the first sliding block, and is movably connected to the winding wheel.

[0016] Beneficial effects

[0017] This invention provides a photovoltaic-diesel energy storage and charging power supply device. Compared with the prior art, it has the following advantages:

[0018] 1. This photovoltaic-diesel storage and charging power supply device starts the servo motor on the mounting plate, causing the output end of the servo motor to drive the left lead screw to rotate. Then, through the pulley and belt transmission, the two lead screws rotate simultaneously. The lead screws drive the first sliding block to move up and down in the inner cavity of the first and second drive seats, thereby moving the sleeve plate. At the same time, the heating plate in the inner cavity of the sleeve plate is opened, and the heating plate starts to heat up. With the up and down movement, the heat energy emitted by the heating plate is evenly dissipated into the inner cavity of the control cabinet, thereby heating the inner cavity of the control cabinet. This prevents the electrical components in the inner cavity of the control cabinet from becoming too damp, thereby improving the service life of the electrical components. This solves the problem that existing diesel generator sets are equipped with control cabinets for controlling the operation of diesel generator sets. However, because the diesel generator sets are located indoors, sometimes the environment is humid, which can cause a lot of moisture to accumulate in the inner cavity of the control cabinet. Long-term moisture will reduce the life of the electrical components in the inner cavity of the control cabinet.

[0019] 2. In this photovoltaic-diesel storage and charging power supply device, when the lead screw drives the first sliding block to move up and down, the winding wheel inside the first sliding block rotates and moves along with the first sliding block as the lead screw rotates, thereby tightening the steel wire rope. This causes one end of the steel wire rope to drive the second sliding block to slide on one side within the inner cavity of the connecting plate. Simultaneously, the slider slides along with the sliding groove. As the second sliding block moves, the spring is compressed, and the infrared thermal sensor camera starts to activate. As the sliding occurs, it senses the temperature of various nodes of the electrical components inside the control cabinet. When the temperature exceeds the normal range, the data is transmitted to the backend for maintenance personnel to inspect. In addition, when the lead screw flips, the first sliding block drives the winding wheel to rotate downwards, releasing the steel wire rope. Under the spring force, the infrared thermal sensor camera drives the steel wire rope to reset, causing it to move back and forth left and right. This predictive mechanism solves the problem of short circuits that cannot be prevented in advance, which would require replacing electrical components inside the control cabinet and cause damage.

[0028] The technical solutions in the embodiments of the present invention have been clearly and completely described. 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.

[0029] Please see Figure 1-2 The present invention provides a technical solution: a photovoltaic-diesel storage and charging power supply device, including a diesel generator set 1, a control cabinet 2 fixedly installed at one end of the diesel generator set 1, and a moisture-proof short-circuit device 3 installed in the inner cavity of the control cabinet 2;

[0030] Please see Figure 3-6The moisture-proof short-circuit device 3 includes a first drive seat 31 and a second drive seat 32. A lead screw 34 is rotatably sleeved within the inner cavity of the first drive seat 31 and the second drive seat 32. A pulley 39 is fixedly sleeved on the top of the lead screw 34. A belt 310 is movably sleeved on the surface of the pulley 39. A servo motor 38 is fixedly connected to the top of the left lead screw 34. A mounting plate 311 is fixedly connected to the surface of the servo motor 38. A strip-shaped through hole 33 is fixedly opened on the surface of the first drive seat 31. A first sliding block 35 is threaded onto the surface of the lead screw 34. A sleeve plate 318 is fixedly connected to the surface of the first sliding block 35. A heating plate 319 is fixedly sleeved on the opposite side of the sleeve plate 318. A connecting plate 36 is fixedly connected to the opposite side of the sleeve plate 318. A winding wheel 312 is rotatably sleeved within the inner cavity of the left first sliding block 35. A second sliding block 313 is slidably sleeved within the inner cavity of the connecting plate 36. A belt 310 is fixedly sleeved on the surface of the second sliding block 313. An infrared thermal sensor camera 314 is connected to the control cabinet 2. A sliding groove 315 is symmetrically fixed to the inner wall of the connecting plate 36. A slider 316 is symmetrically fixed to the surface of the second sliding block 313. A spring 317 is fixedly connected to one end of the slider 316. A steel wire rope 37 is fixedly connected to the surface of the second sliding block 313. A servo motor 38 is fixedly connected to the top of the diesel generator set 1. The surface of the lead screw 34 penetrates the top of both the diesel generator set 1 and the control cabinet 2. The surface of the first sliding block 35 matches the inner cavity of the first drive seat 31 and the second drive seat 32. A winding wheel 312 is threaded onto the surface of the left lead screw 34, and the winding wheel 312 is located in the inner cavity of the left first sliding block 35. The opposite sides of the first drive seat 31 and the lead screw 34 are fixedly connected to the left and right inner walls of the control cabinet 2. The slider 316 is slidably fitted into the inner cavity of the sliding groove 315, and the surface of the second sliding block 313 is fixed to the connecting plate 36. The inner cavities of the two parts fit together. The spring 317 is located in the inner cavity of the slide 315, and one end of the spring 317 is fixedly connected to the inner wall of the slide 315. One end of the wire rope 37 passes through the inner wall of the heating plate 319 and extends to one end of the heating plate 319. One end of the wire rope 37 passes through the inner cavity and surface of the strip-shaped through hole 33 and the first sliding block 35, and is movably connected to the winding wheel 312.

[0031] In use, the servo motor 38 on the surface of the mounting plate 311 is started, causing the output end of the servo motor 38 to drive the left lead screw 34 to rotate. Then, through the transmission relationship between the pulley 39 and the belt 310, both lead screws 34 rotate simultaneously. The lead screws 34 drive the first sliding block 35 to move up and down within the inner cavities of the first drive seat 31 and the second drive seat 32, thereby moving the sleeve plate 318. At the same time, the heating plate 319 inside the inner cavity of the sleeve plate 318 is opened, causing the heating plate 319 to start heating. With the up and down movement, the heat energy emitted by the heating plate 319 is evenly dissipated into the inner cavity of the control cabinet 2, thereby heating the inner cavity of the control cabinet 2. This prevents the electrical components inside the control cabinet 2 from becoming too damp, improving the service life of the electrical components. Then, when the lead screw 34 drives the first sliding block 35 to move up and down, the first sliding block 35... The inner rotating sleeve of the winding wheel 312 will rotate and move along with the first sliding block 35 as the lead screw 34 rotates, thereby tightening the wire rope 37. This causes one end of the wire rope 37 to drive the second sliding block 313 to slide on one side within the inner cavity of the connecting plate 36. At the same time, the slider 316 will slide along with the slider in the inner cavity of the groove 315. As the second sliding block 313 moves, the spring 317 will be compressed. Simultaneously, the infrared thermal sensor 314 will start and, as it slides, sense the temperature of various nodes of the electrical components inside the control cabinet 2. When the temperature exceeds the normal range, the data will be transmitted to the backend for maintenance workers to inspect. In addition, when the lead screw 34 flips, its first sliding block 35 will drive the winding wheel 312 to rotate downwards, releasing the wire rope 37. Under the elastic force of the spring 317, the infrared thermal sensor camera 314 will drive the wire rope 37 to reset, causing it to move back and forth left and right. By predicting in advance, the problem of short circuits that cannot be prevented in advance can be solved, which would require the replacement of electrical components in the control cabinet cavity and cause damage.

[0032] Please see Figure 7 First, the diesel generator set 1 is connected to the intelligent diesel-storage power station. The intelligent diesel-storage power station is installed in a large open space with good sunlight all year round. The intelligent diesel-storage power station consists of an energy management system, a battery management system, an energy storage battery, an energy storage AC device, a photovoltaic array, and an inverter. Then, it is electrically connected through wires. Its function is as follows.

[0033] 1. When the load is low and the photovoltaic capacity is greater than the load, the photovoltaic system supplies power to the load and charges the energy storage at the same time. After the energy storage is fully charged, the excess power is sent back to the grid for sale.

[0034] 2. When the load is large, both photovoltaic power and mains power supply can power the load simultaneously;

[0035] 3. When the load is large or peak load occurs, the mains power, photovoltaic, and energy storage systems discharge to supplement the load;

[0036] 4. To achieve peak shaving and valley filling, ensure the safe operation of transformers, and improve power supply stability;

[0037] 5. When the load is particularly heavy, the diesel generator set can also be started.

[0038] 6. When the mains power fails or is restricted, it seamlessly switches to photovoltaic and energy storage to power the load. When the energy storage capacity is insufficient, the diesel generator set powers the load and charges the energy storage at the same time.

[0039] Its effects include: saving fossil energy consumption, reducing system costs, reducing pollutant emissions, enabling the system to operate 24 hours a day without interruption of power supply (with backup power supply within 20ms in case of mains power failure); and providing safe power supply with dual backup power of energy storage and diesel.
