Renewable energy power generation generally refers to hydropower generation, wind power generation, biomass power generation, solar power generation, ocean energy power generation, geothermal energy power generation, etc.

[0003] When carrying out renewable energy power generation, the power generation equipment is generally installed in an open area outdoors. Structures such as energy storage equipment supporting the power generation mechanism need a good installation environment to ensure the long-term stable operation of the power generation equipment. The existing protection mechanism for renewable energy power generation equipment has a simple structure and can only play a minor protection role. However, since the renewable energy power generation equipment needs to be installed in the same place for several years or even more than ten years, the existing protection mechanism has a poor protection effect and cannot completely insulate the internal power generation equipment from the external protection device, which may cause electric shock accidents; after long-term use, external soil dust will enter the equipment interior through the heat dissipation mechanism, thus affecting the normal operation of the equipment; at the same time, in areas with large day-night temperature differences or high air humidity, the power generation equipment may be damaged due to high humidity or affect its service life, which is not conducive to ensuring the normal operation of the power generation equipment.

[0009] Preferably, the high-pressure blower mechanism includes a connecting pipe and a high-pressure blower pipe. The bottom of the two outlet pipes and the corresponding parts of the three-way solenoid valve are connected to the connecting pipe.

[0020] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figs. 1 to 4 The embodiments are described in detail below.

[0021] This embodiment provides a protective device for renewable energy power generation equipment, as shown in the attached figure. Figs. 1-4 As shown, the device includes a protective box 1 and a top protective plate 2 fixedly installed on its upper surface. The top protective plate 2 provides overall protection for the protective box 1, preventing rainwater from entering the interior. Support legs are fixedly connected to the four corners of the lower surface of the protective box 1 to support it. An insulating layer 3 is bonded to the inside of the protective box 1, and an inner box 4 for installing equipment is fixedly connected inside the insulating layer 3. Doors are hinged to both sides of the front of the protective box 1, and the inner surface of the doors is also bonded with an insulating layer 3. When the doors are closed, the power generation equipment inside the inner box 4 is in a relatively insulated space, only exposed to light through... The wire is connected to the external equipment, which can effectively insulate the power generation equipment and prevent the protective box 1 from becoming live due to leakage of the power generation equipment, thus avoiding electric shock to personnel who come into contact with the protective box 1. The middle of both sides of the insulation layer 3 is fixedly connected with a protective sleeve 8 through which the wire can pass. The protective sleeve 8 passes through the side of the protective box 1, thus completely insulating the inner box 4 and the wire from the protective box 1. The inner box 4 has slots on both sides corresponding to the protective sleeve 8. The connecting wire of the power generation equipment in the inner box 4 passes through the protective sleeve 8 and connects to the external equipment. The protective sleeve 8 can prevent the connecting wire from contacting the protective box 1 at all, further improving the insulation effect.

[0022] The protective box 1, the insulation layer 3, and the inner box 4 all have corresponding ventilation holes 5 on their top and bottom sides. The ventilation holes 5 on the top sides of the protective box 1 are fixedly connected to filter screens that can play a certain filtering role, which can further improve the protective performance of the protective box 1. The top sides of the protective box 1 are fixedly installed with first electrostatic dust-absorbing plates 6 that can adsorb dust. The two first electrostatic dust-absorbing plates 6 correspond to the ventilation holes 5 on the top sides of the protective box 1. When the outside air flows into the inner box 4 through the ventilation holes 5 on the top sides of the protective box 1, the first electrostatic dust-absorbing plates 6 can adsorb the dust and other small particles in the air flowing through it, thereby effectively preventing dust and other impurities from entering the interior of the inner box 4.

[0023] A drying mechanism for dehumidifying the interior of the inner box 4 is provided on the bottom of one side of the protective box 1. The drying mechanism includes a drying fan 9, an air outlet pipe 10, and a three-way solenoid valve 11. There are two drying fans 9, and both drying fans 9 are fixedly installed on the bottom of the same side of the protective box 1. The air outlet pipe 10 is fixedly installed on the inner wall of the inner box 4 at the position corresponding to the air outlet end of the drying fan 9 and is connected to the drying fan 9. The bottom of the protective box 1, the insulation layer 3, and the inner box 4 are all provided with slots that can communicate with the air outlet pipe 10 at the positions corresponding to the drying fan 9, so as to ensure that the drying fan 9 can blow air into the inner box 4 through the air outlet pipe 10, thereby drying and dehumidifying the interior of the inner box 4, reducing the humidity inside the inner box 4, and ensuring the normal operation of the power generation equipment. The three-way solenoid valve 11 is fixedly installed on the side of the air outlet pipe 10. There are two air outlet pipes 10 and two three-way solenoid valves 11. The two air outlet pipes 10 are respectively connected to the air outlet ends of the two drying fans 9 and are fixedly connected to the bottom of the inner wall of the inner box 4.

[0024] The output end of the drying mechanism is equipped with a high-pressure blower mechanism, which includes a connecting pipe 12 and a high-pressure blower pipe 13. The bottom of the two outlet pipes 10, corresponding to the three-way solenoid valve 11, are connected to the connecting pipe 12. The three-way solenoid valve 11 can control the flow of air in the outlet pipes 10 and the connecting pipe 12. When it is necessary to dry and dehumidify the inner chamber 4, the three-way solenoid valve 11 is controlled to allow the outlet pipes 10 to flow and the connecting pipe 12 to be closed. The air blown by the drying fan 9 will enter the inner chamber 4 from the outlet pipes 10 to dry and dehumidify the inner chamber 4. There are several high-pressure blower pipes 13, and these high-pressure blower pipes 13 are equidistantly and fixedly connected to the connecting pipe 12. The high-pressure blower 13 is positioned near the side of the second electrostatic dust-collecting plate 7, and its outlet is horizontally aligned with the second electrostatic dust-collecting plate 7. When it is necessary to clean the dust particles adsorbed on the second electrostatic dust-collecting plate 7, the three-way solenoid valve 11 is controlled to close the outlet pipe 10 and allow the connecting pipe 12 to flow. The air blown out by the drying fan 9 will then be blown outward from the multiple high-pressure blower pipes 13 at the bottom of the connecting pipe 12. The high-pressure blower pipes 13 can accelerate the flow rate of the air, and since the high-pressure blower pipes 13 are aligned with the second electrostatic dust-collecting plate 7, the dust adsorbed on the side of the second electrostatic dust-collecting plate 7 can be blown away, ensuring that the second electrostatic dust-collecting plate 7 always has good adsorption properties.

[0025] A heat dissipation mechanism for cooling the interior of the inner box 4 is fixedly installed on the lower surface of the protective box 1. The heat dissipation mechanism includes a cooling fan 14, a protective cover 15, and a filter 16. There are several cooling fans 14, which are fixedly installed on the lower surface of the protective box 1 in a rectangular array. The protective cover 15 covers the outside of the cooling fans 14 and is fixedly connected to the lower surface of the protective box 1. The inner bottom wall of the protective cover 15 is fixedly connected to a filter 16, which are also several. The filter 16 are fixedly connected to the inner bottom wall of the protective cover 15 at equal intervals. When the cooling fan 14 is running, it can blow external air into the inner box 4 through the ventilation hole 5 at the bottom of the protective box 1, promoting air circulation inside the inner box 4. The filter 16 at the bottom of the protective cover 15 can not only ensure normal air circulation, but also play a certain protective role, preventing insects or impurities from entering the inner box 4.

[0026] The lower surface of the heat dissipation mechanism is provided with a second electrostatic dust-collecting plate 7. Both the first electrostatic dust-collecting plate 6 and the second electrostatic dust-collecting plate 7 are composed of multiple electrostatic plates arranged in parallel with each other. The second electrostatic dust-collecting plate 7 corresponds to the ventilation hole 5 on the bottom wall of the inner wall of the protective box 1. The second electrostatic dust-collecting plate 7 is fixedly connected to the lower surface of the protective cover 15, and several filters 16 correspond to the gaps in the second electrostatic dust-collecting plate 7. When the cooling fan 14 draws air into the inner box 4, the air will first pass through the second electrostatic dust-collecting plate 7. The second electrostatic dust-collecting plate 7 can adsorb dust particles in the air passing through it, and the filters 16 can also block some dust particles, thereby further reducing the dust content entering the inner box 4.

[0027] The upper surface of the protective box 1 is equipped with a monitoring mechanism for monitoring the interior of the inner box 4. This mechanism includes four temperature sensors 17 and four humidity sensors 18. The four temperature sensors 17 are fixedly mounted on the upper surface of the protective box 1 in a rectangular array, with their sensing ends penetrating inside the inner box 4. The humidity sensors 18 are fixedly mounted in the middle of the upper surface of the protective box 1, with their sensing ends also penetrating inside the inner box 4. Both the temperature sensors 17 and humidity sensors 18 are located below the top protective plate 2. These multiple temperature sensors 17 can monitor the temperature of various areas within the inner box 4 in real time, thereby controlling the dynamic operation of the cooling fan 14 via the control unit. When the temperature inside the inner chamber 4 is higher than normal, the cooling fan 14 is controlled to run to dissipate heat from the interior. When the temperature inside the inner chamber 4 is detected to be lower than normal or at normal level, the cooling fan 14 is stopped. This can dynamically adjust the temperature inside the inner chamber 4 and save energy. The humidity sensor 18 can monitor the air humidity inside the inner chamber 4. When the device is in an area with large temperature difference between day and night or high humidity, the humidity inside the inner chamber 4 is also high, which can cause the power generation equipment to short circuit due to dew and also cause it to rust faster. When the humidity sensor 18 detects that the humidity inside the inner chamber 4 is high, the control unit controls the drying fan 9 to run, which can dry and dehumidify the inside of the inner chamber 4.

[0028] The drying fan 9, the three-way solenoid valve 11, the cooling fan 14, the temperature sensor 17, and the humidity sensor 18 are all electrically connected to the external control unit and are all electrically connected to the external circuit through wires.

[0029] In summary, the operating steps for this protective device used in renewable energy power generation equipment are as follows:

[0030] 1. Install the power generation device and its supporting equipment inside the inner box 4, and pass its connecting wires through the protective sleeves 8 on both sides to connect with the external equipment;

[0031] 2. When the temperature inside the inner box 4 is detected to be higher than the normal level, the cooling fan 14 is controlled to run to dissipate heat from the inside. The air passes through the second electrostatic dust collection plate 7, which can adsorb dust particles in the air passing through it. The filter 16 can also block some dust particles, thereby further reducing the amount of dust entering the inner box 4.

[0032] 3. When the humidity sensor 18 detects that the humidity inside the inner box 4 is high, the control unit controls the drying fan 9 to run and dry and dehumidify the inner box 4.

[0033] 4. Operate the drying fan 9 at regular intervals and make the three-way solenoid valve 11 open the connecting pipe 12 to clean the second electrostatic dust collection plate 7 with high-pressure gas at regular intervals, so as to ensure that the second electrostatic dust collection plate 7 has good adsorption properties.

[0034] The above description is only for illustrating the present utility model. It should be understood that the present utility model is not limited to the above embodiments, and various modifications that conform to the concept of the present utility model are within the protection scope of the present utility model.
