Description

Technical Field

[0001] The present invention relates to the field of photovoltaic power generation equipment, and in particular to a photovoltaic power generation and storage integrated device. Background Art

[0002] The photovoltaic and energy storage integrated machine is a device used in photovoltaic power generation systems to realize DC / AC power conversion. It uses electronic control technology to charge the DC power emitted by the photovoltaic components to the energy storage battery according to control needs, and outputs AC power that meets standard requirements to supply power to the load through DC / AC conversion technology. The photovoltaic and energy storage integrated machine generally includes an inverter and an energy storage battery pack. The inverter is used to convert the DC power transmitted by the solar photovoltaic panel or the energy storage battery pack into AC output. The energy storage battery pack is used to store the DC power output by the solar photovoltaic panel and output DC power to the inverter. The inverter and the energy storage battery pack will generate a lot of heat when working. In the case of overheating and short circuit of electrical equipment, it may burn and explode. Once the combustion of local electrical appliances cannot be extinguished in time, the entire photovoltaic power generation system will be damaged. Summary of the invention

[0003] Therefore, it is necessary to provide a photovoltaic and storage integrated machine to solve the problem that a fire in the photovoltaic and storage integrated machine cannot be extinguished in time.

[0004] To achieve the above-mentioned purpose, the present invention provides a photovoltaic and energy storage integrated machine, comprising a chassis, an inverter, an energy storage battery pack, a controller and a flame retardant and fire extinguishing unit, wherein the controller is used to monitor the working state of the energy storage battery pack, a plurality of horizontally arranged fixing plates are arranged inside the chassis, and the fixing plates divide the inside of the chassis into a plurality of placement cavities, and the inverter, the controller, and the energy storage battery pack are arranged in a placement cavity respectively, and the chassis comprises a plurality of columns and a plurality of mounting plates, the front side of the chassis is an open side, and the remaining sides are closed to install the mounting plates, the mounting plates are fixed to the columns on the sides, and a cabinet door is installed on the open side at a position opposite to the placement cavity.

[0005] The flame retardant fire extinguishing unit includes a high-pressure gas storage tank and an air duct. At least one of the columns is hollow. The high-pressure gas storage tank is connected to the hollow column through the air duct. The column is provided with an opening corresponding to the position of the placement cavity. A flame retardant jet pipe is installed on the opening. The flame retardant jet pipe is provided with a plurality of jet ports at intervals along its axial direction. Flame retardant gas is stored in the high-pressure gas storage tank. A pipeline switch is provided on the air duct.

[0006] Furthermore, the jet port has an angle α with the horizontal plane, -60°≤α≤60°, and the angles α of the multiple jet ports are the same or different. The jet ports are arranged at various angles so that the flame-retardant gas can be sprayed to the electrical components in the burning placement cavity in all directions. For the jet port tilted upward, after the gas is sprayed out, it hits the top of the placement cavity and can be turned back downward.

[0007] Furthermore, ventilation holes are provided on the fixing plates between the adjacent placement cavities, and the flame-retardant gas ejected from the upwardly inclined jet nozzles can extinguish the fire on the bottom surface of the upper placement cavity through the ventilation holes, thereby ensuring the fire extinguishing effect.

[0008] Furthermore, a fixing tube is fixed on the opening, the fixing tube is provided with an internal thread, an end of the flame-retardant jet tube close to the opening is provided with an external thread, the flame-retardant jet tube is connected to the fixing tube by threads, a support platform is fixed on the column near the end of the flame-retardant jet tube, the support platform supports the end of the jet tube. The threaded connection method facilitates the rapid installation of the flame-retardant jet tube, and the support platform and the fixing tube jointly support the flame-retardant jet tube to prevent the flame-retardant jet tube from tilting.

[0009] Furthermore, there is a hollow column on each side of the placement cavity, and the flame retardant jet pipes connected to the two hollow columns are arranged opposite to each other. The columns on different sides spray flame retardant gas at the same time, and the flame retardant gas encounters the center of the placement cavity and then quickly distributes throughout the placement cavity.

[0010] Furthermore, a first partition and a second partition are vertically provided on opposite sides of the placement cavity, and the first partition and the second partition are respectively arranged opposite to the two side surfaces of the chassis to form an air inlet channel and an air outlet channel. An air inlet is provided at the top of the air inlet channel, and the bottom of the air inlet channel is closed. An air outlet is provided at the top of the air outlet channel, and an air inlet fan is provided on the air inlet.

[0011] When the optical storage integrated machine is in normal operation, the air intake fan can blow heat dissipation air into the chassis through the air intake channel, effectively reducing the temperature inside the chassis when the device is running.

[0012] The energy storage battery pack is fixed as a whole at the bottom of the photovoltaic and energy storage integrated machine, which can stabilize the center of gravity of the photovoltaic and energy storage integrated machine and make the photovoltaic and energy storage integrated machine stably placed. The inverter dissipates more heat during use. The closer to the top, the higher the wind pressure and the better the heat dissipation effect.

[0013] Furthermore, the flame retardant fire extinguishing unit also includes a control center, the pipeline switch is an electrically controlled switch, the air inlet fan and the electrically controlled switch are electrically connected to the control center, and a smoke detector is provided on the air outlet, and the smoke detector is electrically connected to the control center.

[0014] When the electrical appliance in the placement device catches fire, the smoke detector detects the smoke concentration, the control center controls the air intake fan to stop the air intake, and at the same time the electric control switch is turned on, and the flame retardant jet pipe sprays flame retardant gas into the placement cavity. Since oxygen is isolated, the electrical appliance can be effectively extinguished and flame retarded.

[0015] Furthermore, a first guide plate and a second guide plate are respectively provided on two opposite sides of the air inlet channel, the first guide plate is arranged close to the placement cavity, the opposite sides of the first guide plate and the second guide plate are wavy, a first connecting port is provided on the first guide plate, the first connecting port connects the air inlet channel and the placement cavity, the first connecting port is arranged at the crest position of the first guide plate, and a second connecting port connecting the air outlet channel and the placement cavity is provided on the second partition.

[0016] The crests of the first guide plate and the second guide plate are arranged opposite to each other. When the heat dissipation airflow flows in the air inlet channel, due to the wave-shaped arrangement of the two sides, the air pressure of the heat dissipation airflow changes periodically. When the heat dissipation airflow flows to the crest position, the heat dissipation airflow is compressed and the air pressure increases. The heat dissipation airflow can maintain a high rate of flow into the placement cavity, which is beneficial to the cooling of the inverter, the energy storage battery pack and the controller. At the same time, when the heat dissipation airflow flows to the trough position, the flow area increases and the flow rate of the heat dissipation airflow decreases, which is beneficial to the precipitation of dust in the airflow, preventing dust from entering the cavity and affecting the operation of the electrical appliance.

[0017] Furthermore, a waterproof cavity is formed between the first guide plate and the first partition plate close to the air inlet channel, the waterproof cavity is filled with dry particles, the first connecting port passes through the waterproof cavity, and air holes are provided on the side of the first guide plate.

[0018] The dry particles come into contact with the heat dissipation airflow through the air holes, and can absorb the moisture in the heat dissipation airflow, ensuring that the heat dissipation airflow is in a dry state, thereby preventing the heat dissipation airflow from having too much moisture, which may cause circuit equipment to malfunction.

[0019] Furthermore, the first guide plate and the first partition plate are integrated into a mounting shell, and mounting grooves are provided on the top and bottom surfaces of the placement cavity near the side of the air inlet channel, and the bottom and top edges of the mounting shell are slidably embedded in the mounting grooves. The mounting shell is installed and replaced through the mounting grooves, which facilitates timely replacement of the drying particles in the mounting shell through the mounting grooves, thereby ensuring the dryness of the heat dissipation airflow.

[0020] The above technical solution has the following beneficial effects:

[0021] In the present invention, flame-retardant gas is transported to the placement cavity through the hollow columns. The flame-retardant gas can block oxygen and achieve the effect of extinguishing fire and flame retardant on the electrical components in the placement cavity, thereby ensuring that the photovoltaic power generation system will not be further damaged. At the same time, the flame-retardant gas is transported by the hollow columns without adding a separate transport pipe structure, thereby simplifying the structure of the photovoltaic storage integrated machine and reducing equipment costs. The flame-retardant gas can dissipate naturally after the fire is extinguished, and will not cause damage to the equipment inside the photovoltaic storage integrated machine.

[0037] In order to explain the technical content, structural features, achieved objectives and effects of the technical solution in detail, the following is a detailed description in conjunction with specific embodiments and accompanying drawings.

[0038] See also Figure 1-7 The present embodiment provides a photovoltaic and energy storage integrated machine, including a chassis 1, an inverter 2, an energy storage battery pack 3, a controller 4 and a flame retardant and fire extinguishing unit 5, wherein the controller 4 is used to monitor the working state of the energy storage battery pack 3, the inverter 2 is used to convert the direct current transmitted by the solar photovoltaic panel or the energy storage battery pack 3 into alternating current output, and the energy storage battery pack 3 is used to store the direct current output by the solar photovoltaic panel and output the direct current to the inverter 2.

[0039] In this embodiment, the energy storage battery pack group 3 is connected to the inverter 2, the controller 4 is connected to the energy storage battery pack group 3, and a power supply access port is provided on the side of the chassis 1 of the photovoltaic and storage integrated machine to facilitate connection with the input of the solar photovoltaic panel. The power supply access port is connected to a DC processing module, and then the DC processing module is connected to the inverter 2 and the energy storage battery pack group 3 through wires. The DC processing module filters and boosts the current input by the solar photovoltaic panel.

[0040] A plurality of horizontally arranged fixing plates 11 are provided inside the chassis 1, and the fixing plates 11 divide the interior of the chassis 1 into a plurality of placement cavities 12. The inverter 2, the controller 4, and the energy storage battery pack 3 are correspondingly arranged in one placement cavity 12. The chassis 1 includes a plurality of columns 13 and a plurality of mounting plates 18. The front side of the chassis 1 is an open side, and the remaining sides are closed and installed with the mounting plates 18. The mounting plates 18 are fixed to the columns 13 on the sides. In this embodiment, the mounting plates 18 are arranged on the side, back, top and bottom surfaces of the chassis 1, and a cabinet door 14 is installed on the open side at a position opposite to the placement cavity 12.

[0041] A first partition 16 and a second partition 17 are vertically arranged on opposite sides of the placement cavity 12. The first partition 16 and the second partition 17 are respectively arranged opposite to the two sides of the chassis 1 to form an air inlet channel 6 and an air outlet channel 7. An air inlet 61 is arranged at the top of the air inlet channel 6, and the bottom of the air inlet channel 6 is closed. An air outlet 71 is arranged at the top of the air outlet channel 7, and an air inlet fan 62 is arranged on the air inlet 61. When the optical storage integrated device is in normal operation, the air inlet fan 62 can blow and inhale heat dissipation airflow into the chassis 1 through the air inlet channel 6, effectively reducing the temperature in the chassis 1 when the device is in operation.

[0042] In this embodiment, the chassis 1 is rectangular and includes eight columns 13 which are divided into two groups and are respectively located on two opposite sides of the fixing plate 11 . The air inlet channel 6 and the air outlet channel 7 correspond to one group of columns 13 .

[0043] In this embodiment, the energy storage battery pack 3 is fixed in the placement cavity 12 at the bottom of the chassis 1, and the inverter 2 is fixed in the placement cavity 12 at the top of the chassis 1. The energy storage battery pack 3 is fixed as a whole at the bottom of the photovoltaic and storage integrated machine, which can stabilize the center of gravity of the photovoltaic and storage integrated machine, so that the photovoltaic and storage integrated machine can be stably placed. The inverter 2 dissipates more heat during use. The closer to the top, the higher the wind pressure and the better the heat dissipation effect.

[0044] A first guide plate 63 and a second guide plate 64 are respectively provided on two opposite sides of the air inlet channel 6. The first guide plate 63 is arranged close to the placement cavity 12. The opposite sides of the first guide plate 63 and the second guide plate 64 are wavy. A first connecting port 65 is provided on the first guide plate 63. The first connecting port 65 connects the air inlet channel 6 and the placement cavity 12. The first connecting port 65 is arranged at the crest position of the first guide plate 63. A second connecting port 72 connecting the air outlet channel 7 and the placement cavity 12 is provided on the second partition plate 17.

[0045] The crests of the first guide plate 63 and the second guide plate 64 are arranged relative to each other. When the heat dissipation airflow flows in the air inlet channel 6, due to the wavy arrangement of the two side edges, the air pressure of the heat dissipation airflow changes periodically. When the heat dissipation airflow flows to the crest position, the heat dissipation airflow is compressed and the air pressure increases. The heat dissipation airflow can maintain a high rate of flow into the placement cavity 12, which is beneficial to the cooling of the inverter 2, the energy storage battery pack 3 and the controller 4. At the same time, when the heat dissipation airflow flows to the trough position, the flow area increases and the flow rate of the heat dissipation airflow decreases, which is beneficial to the precipitation of dust in the airflow, preventing dust from entering the cavity and affecting the operation of the electrical appliance.

[0046] In this embodiment, the first communication opening 65 and the second communication opening 72 correspond to the central position of the placement cavity 12 , and a wave crest structure is provided on the first guide plate 63 corresponding to each placement cavity 12 .

[0047] In another implementation manner, a plurality of wave peak structures may be provided on the first guide plate 63 corresponding to each placement cavity 12 .

[0048] A waterproof cavity 631 is formed between the first guide plate 63 and the first partition plate 16 near the air inlet channel 6 . The waterproof cavity 631 is filled with dry particles 632 . The first connecting port 65 passes through the waterproof cavity 631 . A vent hole 633 is provided on the side of the first guide plate 63 .

[0049] The dry particles 632 are in contact with the heat dissipation airflow through the air holes 633, and can absorb moisture in the heat dissipation airflow to ensure that the heat dissipation airflow is in a dry state, thereby preventing the heat dissipation airflow from being filled with too much moisture, which may cause circuit equipment to malfunction.

[0050] In this embodiment, the drying particles 632 are color-changing silica gel particles. When the color-changing silica gel particles absorb water, the color of the color-changing silica gel particles changes, thereby indicating the degree of water absorption of the color-changing silica gel and reminding the staff to replace it in time.

[0051] In another embodiment, the first baffle 16 is wavy (not shown in the drawings), and the first baffle 16 is the first guide plate 63. The first baffle 16 is wavy, which can not only isolate the air inlet channel 6 and the placement cavity 12, but also play the role of guiding the first guide plate 63.

[0052] In order to remove moisture from the airflow, the first guide plate 63 and the first partition plate 16 are integrated into a mounting shell, and mounting grooves 66 are provided on the top and bottom surfaces of the placement cavity 12 near the sides of the air inlet channel 6, and the bottom and top edges of the mounting shell are slidably embedded in the mounting grooves 66. The mounting shell is installed and replaced through the mounting grooves 66, which facilitates the timely replacement of the drying particles 632 in the mounting shell by the mounting grooves 66, thereby ensuring the dryness of the heat dissipation airflow.

[0053] In the present invention, dust accumulation grooves 67 are horizontally extended along the width direction on the opposite sides of the first guide plate 63 and the second guide plate 64. The dust accumulation grooves 67 are used to deposit fine dust in the heat dissipation airflow to prevent dust from entering the placement cavity 12.

[0054] The cross section of the dust accumulation groove 67 may be polygonal or arc-shaped. In this embodiment, the cross section of the dust accumulation groove 67 is rectangular, and the air holes 633 are arranged on the upper side of the dust accumulation groove 67. When the first guide plate 63 and the second guide plate 64 are arranged in a detachable installation mode, after the device is used for a period of time, the first guide plate 63 and the second guide plate 64 can be removed for cleaning and then reinstalled.

[0055] Furthermore, in order to ensure the air pressure of the heat dissipation airflow in the bottom placement cavity 12, the peak height of the second guide plate 64 gradually increases from top to bottom (not shown in the drawings). The heat dissipation airflow flows from top to bottom, and there is continuous airflow entering the placement cavity 12 through the first connecting port 65. The flow rate of the heat dissipation airflow gradually decreases. The increase in the peak height of the second guide plate 64 can reduce the ventilation area between the peaks of the first guide plate 63 and the second guide plate 64, so that a relatively high flow rate can still be maintained at the bottom of the air inlet channel 6 to blow toward the placement cavity 12.

[0056] A closing plate 15 is installed on the open side at a position opposite to the air inlet channel 6 and the air outlet channel 7, and the corresponding closing plate 15 on the air inlet channel 6 can be detachably installed. The staff can operate the electrical appliances in the optical storage integrated machine by opening the cabinet door 14, dismantling the closing plate 15 on the air inlet channel 6, and taking out the first guide plate 63 and the second guide plate 64 to clean the dust thereon.

[0057] The flame retardant fire extinguishing unit 5 includes a high-pressure gas storage tank 51 and an air duct 52. At least one column 13 is hollow. The high-pressure gas storage tank 51 is connected to the hollow column 13 through the air duct 52. The column 13 is provided with an opening 53 corresponding to the position of the placement cavity 12. A flame retardant jet pipe 54 is installed on the opening 53. The flame retardant jet pipe 54 is provided with a plurality of jet ports 55 at intervals along its axial direction. Flame-retardant gas is stored in the high-pressure gas storage tank 51, and a pipeline switch 521 is provided on the air duct 52.

[0058] The jet port 55 has an angle α with the horizontal plane, -60°≤α≤60°, and the angles α of the plurality of jet ports 55 are the same or different. The jet ports 55 are arranged at various angles so that the flame-retardant gas can be sprayed in all directions to the electrical components in the burning placement cavity 12. After the gas is sprayed out from the jet port 55 inclined upward, it hits the top of the placement cavity 12 and can be turned back downward.

[0059] In this embodiment, there are five kinds of angles α between the air jet 55 and the horizontal plane, namely, -60°, -30°, 0°, 30°, and 60°.

[0060] The fixing plate 11 between the adjacent placement cavities 12 is provided with ventilation holes 111. The flame-retardant gas ejected from the upwardly inclined jet port 55 can extinguish the bottom surface of the upper placement cavity 12 through the ventilation holes 111, thereby ensuring the fire extinguishing effect.

[0061] A fixing pipe 56 is fixed to the opening 53, and the fixing pipe 56 is provided with an internal thread. An end of the flame retardant jet pipe 54 close to the opening 53 is provided with an external thread. The flame retardant jet pipe 54 and the fixing pipe 56 are connected by threads. A support platform 57 is fixed to the position close to the end of the flame retardant jet pipe 54 on the column 13, and the support platform 57 supports the end of the jet pipe. The threaded connection method facilitates the rapid installation of the flame retardant jet pipe 54, and the support platform 57 and the fixing pipe 56 jointly support the flame retardant jet pipe 54 to prevent the flame retardant jet pipe 54 from tilting.

[0062] In this embodiment, a sealing rubber ring can be provided at the screw connection between the fixed tube 56 and the flame retardant air injection tube 54 to prevent air leakage. The support platform 57 is arc-shaped, corresponding to the circular flame retardant air injection tube 54. Three rows of vent holes 111 are provided on the fixed plate 11. The fixing method of the fixed plate 11 and the column 13 can be that a supporting boss (not shown in the drawings) is provided on the column 13, and the fixed plate 11 is placed on the fixed boss.

[0063] Specifically, there is a hollow column 13 on each side of the placement cavity 12, and the flame-retardant air injection pipes 54 connected to the two hollow columns 13 are arranged opposite to each other.

[0064] The columns 13 on different sides spray the flame-retardant gas at the same time, and the flame-retardant gas encounters the center of the placement cavity 12 and then quickly distributes to the entire placement cavity 12 .

[0065] In this embodiment, the flame retardant gas is carbon dioxide or nitrogen, which not only plays a flame retardant role of isolating oxygen, but also acts as an insulating medium to prevent electrical circuit failure.

[0066] The flame retardant and fire extinguishing unit 5 also includes a control center 58, the pipeline switch 521 is an electric control switch, the air inlet fan 62 and the electric control switch are electrically connected to the control center 58, and a smoke detector is provided on the air outlet 71, and the smoke detector is electrically connected to the control center 58. When the electrical appliance in the placement device catches fire, the smoke detector detects the smoke concentration, the control center 58 controls the air inlet fan 62 to stop the air intake, and at the same time the electric control switch is turned on, and the flame retardant jet pipe 54 sprays the flame retardant gas into the placement cavity 12. Since oxygen is isolated, the electrical appliance can be effectively extinguished and flame retardant.

[0067] When the present invention is used:

[0068] Conventional heat dissipation state: When the inverter 2, the energy storage battery pack 3, and the controller 4 are working normally, a large amount of heat is dissipated. At this time, the control center 58 controls the air inlet fan 62 to turn on, and the heat dissipation airflow enters the air inlet channel 6. Since the first guide plate 63 and the second guide plate 64 are wave-shaped, the heat dissipation airflow has the maximum air pressure at the crest of the wave and can enter the placement cavity 12 at a relatively high speed to dissipate heat for the inverter 2, the controller 4, and the energy storage battery pack.

[0069] Flame retardant fire extinguishing state: when combustion occurs in the placement cavity 12, the detector of the air outlet 71 detects a smoke signal, and the control center 58 controls the air inlet fan 62 to stop, stops delivering oxygen, and simultaneously opens the pipe switch 521 on the air duct 52, and the flame retardant gas passes through the air duct 52, the inside of the hollow column 13, and the flame retardant jet pipe 54, and is ejected from the jet port 55. The flame retardant gas can isolate oxygen, thereby playing an effective role in extinguishing the fire.
