Technical Field

[0001] This utility model relates to the field of energy technology, and in particular to a photovoltaic power storage and multi-energy coupling and complementarity device. Background Technology

[0002] With the continuous growth of energy demand and the pursuit of clean energy, photovoltaic power generation has been widely used as an important way to utilize renewable energy. However, photovoltaic power generation is characterized by intermittency and instability, and its output power is greatly affected by factors such as sunlight intensity and weather.

[0003] To improve the stability and reliability of photovoltaic power generation systems and achieve efficient utilization of electrical energy, it is necessary to introduce energy storage devices and multi-energy coupling and complementary technologies. Currently, some photovoltaic energy storage and multi-energy coupling and complementary devices on the market have many shortcomings in structural design and functional implementation. For example, the connection between the energy storage device and the photovoltaic module is not stable or efficient enough, the inverter's protection performance is poor, and it is easily affected by external factors, leading to a shortened lifespan of the entire device and a reduction in energy conversion efficiency.

[0004] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: photovoltaic energy storage and multi-energy coupling complementary devices have many shortcomings in structural design and functional implementation, the connection of photovoltaic modules is not stable and efficient enough, the protection performance of inverters is poor, and they are easily affected by external factors, which affects their normal operation; therefore, in order to address the above problems, a photovoltaic energy storage and multi-energy coupling complementary device is proposed. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing photovoltaic energy storage and multi-energy coupling complementary devices, which have many deficiencies in structural design and functional implementation, such as unstable and inefficient connection of photovoltaic modules, poor protection performance of inverters, and susceptibility to interference from external factors affecting their normal operation. Therefore, this invention proposes a photovoltaic energy storage and multi-energy coupling complementary device.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a photovoltaic energy storage and multi-energy coupling complementary device, comprising a photovoltaic module, an energy storage device electrically connected to the photovoltaic module, an inverter mounted on the surface of the photovoltaic module, a connecting line electrically connected to one side of the energy storage device, the connecting line being electrically connected to the input terminal of the inverter, an output terminal on the side wall of the inverter, operation buttons on the surface of the inverter, a protective device on the surface of the inverter, the protective device comprising a U-shaped plate, the U-shaped plate being fixedly connected to the surface of the inverter, a rotating rod rotatably connected to the inner wall of the U-shaped plate, a protective plate fixedly connected to the arc surface of the rotating rod, a fixing hole on the side wall of the protective plate, a support plate fixedly connected to the surface of the inverter, a sliding rod slidably connected inside the support plate, a pull plate fixedly connected to one end of the sliding rod, and the size of the sliding rod being adapted to the size of the fixing groove of the protective plate.

[0007] The aforementioned components achieve the following effects: by setting up a protective device, the operation buttons on the inverter are protected. When the inverter is not in operation, the protective plate rotates to cover the operation buttons, and the protective plate is fixed by inserting a sliding rod into the fixing hole. This effectively prevents foreign objects from contacting the operation buttons, reduces inverter malfunctions caused by button damage, ensures stable inverter operation, and thus improves the reliability and safety of the entire device.

[0012] Preferably, the arc surface of the rotating rod is fitted with two torsion springs, and the two ends of the torsion springs are fixedly connected to the U-shaped plate and the protective plate, respectively.

[0013] The aforementioned components achieve the following effect: under the force of the torsion spring, the protective plate is automatically opened and maintained at a certain angle, making it easier for staff to operate the control buttons and improving the practicality of the device.

[0014] Preferably, the inverter is provided with clamping devices on both sides. The clamping devices include two support plates, which are fixedly connected to both sides of the inverter respectively. Two fixing plates are fixedly connected to both sides of the inverter.

[0016] Preferably, a protective pad is fixedly connected to one end of the clamping plate, and the protective pad is made of silicone.

[0017] The effect achieved by the above components is that by setting up protective pads, the connecting wires are protected, avoiding bending and damage caused by long-term clamping, thus improving the practicality of the device.

[0018] Preferably, a sliding rod is fixedly connected to one side of the clamping plate, and the arc surface of the sliding rod is slidably connected to the fixed plate.

By setting the protective device 5, the operation buttons on the inverter 4 are protected. When the inverter 4 is not in operation, the protective plate 53 rotates to cover the operation buttons, and a sliding rod is used to... The protective plate 53 is fixed by inserting the fixing hole 55, which effectively prevents foreign objects from contacting the operation buttons, reduces the failure of the inverter 4 caused by button damage, ensures the stable operation of the inverter 4, and thus improves the reliability and safety of the entire device. This is conducive to the continuous and efficient development of photovoltaic energy storage and multi-energy coupling and complementarity. The inverter 4 is equipped with clamping devices 6 on both sides. By setting the clamping devices 6, the connecting wires 3 connected to the inverter 4 are clamped and fixed, which prevents the connecting wires 3 from being dragged by other external factors, causing the connecting wires 3 to detach from the inverter 4, thereby affecting the photovoltaic energy storage and multi-energy coupling and complementarity, and improving the practicality of the device.

[0030] The specific design and function of its protective device 5 and clamping device 6 will be explained below.

[0031] Reference Figures 2-5As shown in this embodiment: the protective device 5 includes a U-shaped plate 51, which is fixedly connected to the surface of the inverter 4. A rotating rod 52 is rotatably connected to the inner wall of the U-shaped plate 51. A protective plate 53 is fixedly connected to the arc surface of the rotating rod 52. A fixing hole is provided on the side wall of the protective plate 53. A support plate 54 is fixedly connected to the surface of the inverter 4. A sliding rod 55 is slidably connected inside the support plate 54. A pull plate 56 is fixedly connected to one end of the sliding rod 55. The size of the sliding rod 55 is adapted to the size of the fixing groove of the protective plate 53. A spring 57 is sleeved on the arc surface of the sliding rod 55. The two ends of the spring 57 are fixedly connected to the pull plate 56 and the support plate 54, respectively. By setting the spring 57, self-protection is achieved. The sliding rod 55 is automatically pushed into the fixing groove of the protective plate 53, which improves the practicality of the device. The surface of the inverter 4 is fixedly connected to the support plate 58, and the surface of the support plate 58 is fixedly connected to the soft pad. By setting the support plate 58, the protective plate 53 is supported, which makes it easier for the sliding rod 55 to slide into the fixing groove of the protective plate 53, thus improving the practicality of the device. The arc surface of the rotating rod 52 is fitted with two torsion springs 59. The two ends of the torsion springs 59 are fixedly connected to the U-shaped plate 51 and the protective plate 53 respectively. Under the action of the torsion springs 59, the protective plate 53 is automatically opened and maintained at a certain angle, which makes it easier for the staff to operate the operation buttons, thus improving the practicality of the device.

[0032] Reference Figure 6 As shown, specifically, the clamping device 6 includes two support plates 61, which are fixedly connected to both sides of the inverter 4. Two fixing plates 62 are fixedly connected to both sides of the inverter 4. Threaded rods 63 are threaded into the fixing plates 62.

By setting the sliding rod 66, the clamping plate 64 is positioned and guided, further improving the practicality of the device.

[0033] In terms of energy conversion and transmission, the photovoltaic module 1 converts solar energy into electrical energy, which is then transmitted to the inverter 4 via the stable energy storage device 2 and the connecting line 3. The electrical energy from the energy storage device 2 and the output electrical energy from the photovoltaic module 1 are coupled and complemented by the inverter 4 to meet the power demand. When it is necessary to protect the operation buttons on the inverter 4, the protective plate 53 is rotated to cover the operation buttons, and the pull plate 56 is pulled to drive the sliding rod 55 to slide within the support plate 54. The spring 57 is in a stretched state until the protective plate 53 contacts the soft pad on the support plate 58. Then, the pull plate 56 is released, and the sliding rod 55 automatically springs into the fixing groove of the protective plate 53 under the force of the spring 57, fixing the protective plate 53 and preventing dust and foreign objects from contacting the operation buttons.

[0034] When it is necessary to clamp the connected cable 3, insert the connected cable 3 into the inverter 4. The connected cable 3 abuts against the surface of the support plate 61. Rotate the threaded rod 63 to rotate within the fixed plate 62. The clamping plate 64 drives the sliding rod 66 to slide within the fixed plate 62 until the soft pad on the clamping plate 64 abuts against the connected cable 3, thereby clamping and fixing the connected cable 3 connected to the inverter 4.
