Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic energy storage equipment technology, specifically relating to a photovoltaic energy storage DC-flexible power station. Background Technology

[0002] A photovoltaic-storage-direct-drive-flexible power station is a power station that combines a photovoltaic power generation system with an energy storage system. It can store excess electricity while generating photovoltaic power and release the electricity when needed. It is mainly used for power production and supply, providing stable power support to the power grid. With the rapid development of clean energy technology, photovoltaic-storage-direct-drive-flexible power stations have been widely used in the energy field due to their own advantages.

[0003] As an energy storage system in a photovoltaic-storage power station, the integrated photovoltaic-storage unit is typically installed next to the corresponding connected solar photovoltaic panels. In large-scale integrated power stations, a large number of solar photovoltaic panels and corresponding integrated photovoltaic-storage units are placed. Currently, the installation of integrated photovoltaic-storage units is relatively simple, directly fixed to a concrete base. Although this method is quick and stable, the large number of integrated photovoltaic-storage units occupies a significant amount of space. Especially when the integrated photovoltaic-storage units need to be placed indoors, how to effectively place more integrated photovoltaic-storage units in limited space, while also considering that the integrated photovoltaic-storage units themselves generate heat, has become an urgent problem to be solved in order to ensure that the integrated photovoltaic-storage units can save installation space without affecting heat dissipation.

[0004] Based on this, the present invention provides a photovoltaic-storage DC-flexible power station to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a photovoltaic-storage DC-flexible power station to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a photovoltaic-storage integrated power station, comprising a solar photovoltaic panel, a photovoltaic-storage integrated unit, an inspection door, and a mounting frame. The bottom of the solar photovoltaic panel is fixedly connected to the mounting frame, and one side of the solar photovoltaic panel is connected to the photovoltaic-storage integrated unit via a cable. The front of the photovoltaic-storage integrated unit is hinged to the inspection door via a hinge. The bottom of the photovoltaic and energy storage integrated machine is fixedly connected to a double-layer mounting bracket that provides multiple installation spaces. The front of the inspection door is fixedly connected to a heat dissipation component for assisting heat dissipation inside the photovoltaic and energy storage integrated machine. The inner side of the mounting bracket, below the solar photovoltaic panel, is fixedly connected to a cable positioning component for limiting and fixing the cable. The double-layer mounting bracket includes a mounting base plate fixedly connected to the bottom of the integrated photovoltaic storage unit. Connecting rods are fixedly connected to both sides of the mounting base plate. Support blocks are fixedly connected to the ends of the two sets of connecting rods opposite to the mounting base plate. Extension plates are fixedly connected to the ends of the two sets of support blocks opposite to the connecting rods. Multiple support plates are fixedly connected to the top of the two sets of support blocks. Protective nets are fixedly connected between the multiple support plates. A mounting top plate is fixedly connected to the top of the two sets of support plates. Auxiliary support components for supporting force are fixedly connected to the four corners of the bottom of the support plates.

[0007] Using the above scheme, the double-layer mounting bracket provides two vertical installation spaces, allowing two integrated photovoltaic and energy storage units of different specifications to be installed while occupying only one installation space. At the same time, the protective net fixedly connected between the support plates can protect the sides of the integrated photovoltaic and energy storage units and effectively prevent external foreign objects from entering the integrated photovoltaic and energy storage units. The mounting top plate provides a load-bearing structure and fixes the integrated photovoltaic and energy storage units installed there. The support plates and support blocks support the integrated photovoltaic and energy storage units installed on the mounting top plate, and multiple support plates can provide sufficient support force.

[0008] In the above scheme, it should be noted that the fan, controller, and temperature sensor are all electrically connected to an external power supply.

[0009] In a preferred embodiment, the top of the mounting plate is provided with a slot, and the bottom of the slot, the extension plate and the mounting base plate are provided with a number of equally spaced internal threaded mounting holes.

[0010] Using the above scheme, the internal threaded mounting holes at the bottom of the slot, the extension plate, and the mounting base provide necessary support for the stability of the double-layer mounting bracket. The internal threaded mounting holes at the bottom of the slot are fixed by connecting with the integrated photovoltaic storage unit installed here. The internal threaded mounting holes at the extension plate and the mounting base are fixed in position by connecting with the concrete base or other base bolts at the installation location. The threaded connection also facilitates future disassembly.

[0011] In a preferred embodiment, a warning reflective sticker is fixedly connected to the side end of the support plate, and a drain pipe is fixedly connected to the outer surface of the mounting top plate, with one end of the drain pipe penetrating into the slot.

[0012] Using the above solution, the reflective warning stickers can reflect light at night or in dimly lit environments, reminding personnel to avoid collisions. When rainwater or other liquids enter the slot, they can be quickly drained through the drain pipe to prevent water accumulation and corrosion of the equipment, thus ensuring equipment safety.

[0013] In a preferred embodiment, the auxiliary support assembly includes an internally threaded cylinder fixedly connected to the bottom of the mounting plate, the bottom of the internally threaded cylinder being threadedly connected to a screw rod, and the bottom of the screw rod being fixedly connected to a circular support.

[0014] By adopting the above solution, the extension length is adjusted by rotating the screw to make the circular support and the top of the integrated photovoltaic and energy storage unit abut against each other. The auxiliary support components at the four corners make the installation top plate more stable and provide better support stability.

[0015] In a preferred embodiment, the heat dissipation assembly includes a mounting plate fixedly connected to the front of the access door. From left to right, a temperature sensor, a controller, and a fan are connected to the front of the mounting plate, wherein the temperature sensor and the fan are connected to the controller via connecting wires.

[0016] Using the above solution, the temperature sensor monitors the internal temperature of the integrated photovoltaic and energy storage unit in real time and transmits the data to the controller. The controller can then start the fan for forced cooling according to the settings or control of the staff.

[0017] In a preferred embodiment, the air inlet of the fan passes through the mounting plate and extends into the integrated photovoltaic and energy storage unit, the probe end of the temperature sensor passes through the mounting plate and extends into the integrated photovoltaic and energy storage unit, and a warning light is fixedly connected at the lower front part of the mounting plate.

[0018] With the above solution, the air inlet of the fan extends into the integrated photovoltaic and energy storage unit. When the fan starts, the heat inside the integrated photovoltaic and energy storage unit will be drawn out by the fan and discharged to the outside. The temperature sensor is responsible for monitoring the temperature inside the integrated photovoltaic and energy storage unit in real time. The warning light can be turned on after being connected to an external power source. It is mainly used to indicate its own position and provide warning when the lighting conditions are poor.

[0019] In a preferred embodiment, the cable positioning assembly includes two connecting posts fixedly connected to the inside of the mounting frame. A long plate is fixedly connected to the top of the two connecting posts. Limiting components are fixedly connected to both sides of the top of the long plate. Multiple elastic ropes are fixedly connected to the rear of the long plate. A Velcro fastener is fixedly connected to one end of each elastic rope opposite to the long plate.

[0020] Using the above solution, the two limiting components can limit and fix the cable, and the elastic rope and Velcro used together can tighten the cable and enhance the fixing effect.

[0021] In a preferred embodiment, the bottom of the long board is fixedly connected to a reverse hook and loop fastener for use with the forward hook and loop fastener, and the rear of the long board is fixedly connected to a magnetic whiteboard for writing text.

[0022] Using the above solution, the front and back hook and loop fasteners are used together to fix the position of the cable that is bound by the elastic cord. The magnetic whiteboard is used to write text information, which makes it convenient to record important information such as the equipment's coding information, cable information and location in daily work.

[0023] In a preferred embodiment, the limiting component includes an arc-shaped locking block two fixedly connected to the top of the long plate. The top two sides of the arc-shaped locking block two are provided with movable grooves, and a spring providing reciprocating force is fixedly connected to the bottom of the movable groove. The top of the spring is fixedly connected to an arc-shaped locking block one.

[0024] Using the above scheme, when the cable is inserted into the internal space of the arc-shaped clamp 1 and the second arc-shaped clamp 2, the position of the first arc-shaped clamp 1 is changed by the force provided by the spring, and the spring force clamps the cable between the first arc-shaped clamp 1 and the second arc-shaped clamp 2 to prevent the cable from slipping.

[0025] In a preferred embodiment, symmetrically distributed springs are fixedly connected in the movable groove at the top of the second arc-shaped locking block, and the first and second arc-shaped locking blocks have the same inner curvature and are used together.

[0026] Using the above scheme, the symmetrically distributed springs ensure that the clamping force of the arc-shaped clamps on the cable is uniform, and the inner curvature of arc-shaped clamps one and two is the same, which closely fits the outer surface of the cable and improves the reliability of cable limiting and fixing.

[0027] Compared with the prior art, the beneficial effects of this utility model are: The double-layer mounting bracket provides two vertical installation spaces, allowing two different sizes of integrated photovoltaic and energy storage units to be installed in one space. In large-scale systematic production, this effectively reduces the space occupied. The mounting top plate and support plate form a stable support structure, and the protective net blocks foreign objects, achieving both intensive use of space and ensuring safe operation of the equipment. At the same time, vertical installation does not affect the normal heat dissipation of the integrated photovoltaic and energy storage unit. Integrated photovoltaic and energy storage units equipped with double-layer mounting brackets have good advantages whether installed outdoors or indoors.

[0028] The heat dissipation component monitors the internal temperature of the integrated photovoltaic and energy storage unit in real time through a temperature sensor. It can actively extract heat by turning on the fan, forcibly dissipating heat inside the integrated photovoltaic and energy storage unit to prevent performance degradation or failure due to high temperature operation. It can be freely controlled by setting a threshold on the controller or by manually controlling the switch. This component works best when installed in high-density indoor environments. At the same time, this component is installed at the maintenance door, so it does not affect the user's normal use of other functions. The heat dissipation component forcibly exhausts the extracted heat to the front, and there are no obstructions for rapid discharge.

[0029] The cable positioning assembly clamps the cable with the arc-shaped locking block and spring of the limiting component, and uses elastic rope and Velcro to tighten the cable, preventing the cable from shaking, wearing or falling off. The magnetic whiteboard on the long board can record important information such as the coding information of the equipment, cable information and location. This structure not only organizes the cable layout, but also provides information labeling space for maintenance, improving the standardization of power station wiring and maintenance efficiency.

[0038] The cable positioning assembly 6 includes two connecting posts 65 fixedly connected to the inside of the mounting bracket 7. A long plate 61 is fixedly connected to the top of the two connecting posts 65. Limiting components 64 are fixedly connected to both sides of the top of the long plate 61. Multiple elastic ropes 62 are fixedly connected to the rear of the long plate 61.

[0039] The bottom of the long board 61 is fixedly connected to a reverse hook and loop fastener that works with the forward hook and loop fastener 63, and the rear of the long board 61 is fixedly connected to a magnetic whiteboard for writing text. The positive and negative hook and loop fasteners 63 are used together to fix the position of the cable that is bound by the elastic cord 62. The magnetic whiteboard is used to write text information, which makes it convenient to record important information such as the coding information, cable information and location of the equipment in daily work.

[0040] The limiting component 64 includes an arc-shaped locking block 2 643 fixedly connected to the top of the long plate 61. The top two sides of the arc-shaped locking block 2 643 are provided with movable grooves, and a spring 642 providing reciprocating force is fixedly connected to the bottom of the movable groove. The top of the spring 642 is fixedly connected to the arc-shaped locking block 1 641. When the cable is inserted into the internal space of the arc-shaped clamp 643 and the arc-shaped clamp 641, the force provided by the spring 642 causes the position of the arc-shaped clamp 641 to change. The elastic force of the spring 642 causes the arc-shaped clamp 641 and the arc-shaped clamp 643 to clamp the cable and prevent the cable from slipping.

[0041] A symmetrically distributed spring 642 is fixedly connected in the movable groove at the top of the arc-shaped locking block 643.

[0042] According to the requirements of the working environment, a suitable installation location is selected. After the fixed installation location is selected, the integrated photovoltaic storage unit 3 with double-layer mounting bracket 2 is placed in the designated location using hoisting equipment or a forklift. Then, the workers connect the extended plate 25 and the mounting base 27 with bolts through the internal threaded mounting holes, and then fix the position by connecting the current concrete base with bolts. After the position of the lower integrated photovoltaic storage unit 3 is fixed, another integrated photovoltaic storage unit 3 that needs to be fixed is placed on the mounting top plate 21. The mounting top plate 21 can hold integrated photovoltaic storage units 3 of different specifications. Several internal threaded mounting holes on the mounting top plate 21 provide a structure for connecting bolts and integrated photovoltaic storage units 3, which is highly flexible in use. After the position of the integrated photovoltaic storage unit 3 is fixed, the screw 282 is rotated to make the circular support 283 abut against the top of the lower integrated photovoltaic storage unit 3, thereby providing auxiliary support. The double-layer mounting bracket 2 is used to enhance the overall stress stability of the photovoltaic storage unit 3. Power is transmitted via cable connection to the designated solar photovoltaic panel 1. The protective net 23 provides protection without affecting the heat dissipation of the photovoltaic storage unit 3. A heat dissipation component 5 installed at the inspection door 4 monitors the internal temperature of the photovoltaic storage unit 3 in real time. Operators can set a threshold on the controller 53. When the internal temperature of the photovoltaic storage unit 3 exceeds the threshold, the fan 52 is activated for active forced cooling. Whether it activates automatically can be adjusted according to the operator's needs. Alternatively, the fan 52 can be manually connected to an external power source and activated, and then manually deactivated after cooling is complete. The temperature threshold setting on the controller 53 and the control of the fan 52 are mature existing technologies and will not be elaborated further. A temperature sensor 54 monitors the internal temperature of the photovoltaic storage unit 3 to prevent safety hazards caused by excessive temperature. Solar photovoltaic panel 1 The solar panel receives sunlight and converts it into DC power through the photovoltaic effect. The power is then transmitted to the integrated solar energy storage unit 3 via cable. Multiple solar photovoltaic panels 1 are connected and connected by cables to transmit power. The cable positioning component 6 limits the cable position, effectively preventing cable tangling and facilitating later maintenance and daily management. The cable is inserted into the internal space of the arc-shaped locking block 1 641 and arc-shaped locking block 2 643. The elastic force provided by the spring 642 causes the arc-shaped locking block 1 641 to adhere to the cable surface, thereby limiting the cable position. At the same time, the elastic rope 62 and the Velcro 63 provide auxiliary limiting functions, so that the cable can be neatly restrained at the cable positioning component 6.
