Description

Technical Field

[0001] The present application relates to the technical field of power supply node protection equipment, and in particular to a waterproof and anti-corrosion power supply node protection device and method for an agricultural-photovoltaic complementary electrical system. Background Art

[0002] The agricultural photovoltaic complementary electrical system is an important part of the agricultural photovoltaic complementary power generation system. The agricultural photovoltaic complementary electrical system is mainly composed of photovoltaic modules, inverters, combiner boxes, transformers, distribution cabinets and other equipment. Photovoltaic modules are responsible for converting solar energy into direct current, and inverters convert direct current into alternating current so that they can be connected to the power grid or operate independently. The combiner box is used to collect the current generated by multiple photovoltaic modules, and the transformer and distribution cabinet are responsible for the transmission and distribution of electrical energy. In actual applications, power supply nodes are easily damaged by moisture and corrosive substances due to long-term exposure to the natural environment, resulting in frequent system failures and increased maintenance costs. In order to protect the power supply nodes, the common protection measures in the prior art are to install a waterproof cover or apply anti-corrosion paint on the outside of the power supply nodes. Although the above two methods can protect the power supply nodes to a certain extent, the waterproof cover is easily damaged, resulting in rainwater leakage, and the anti-corrosion paint is also prone to aging and falling off. Whether the waterproof cover is damaged or the anti-corrosion paint is aged and falls off, the long-term protection effect of the power supply nodes will be poor. Summary of the invention

[0011] In a specific possible implementation manner, the extension section of the waterproof outer layer extending into the movable sleeve is expanded toward a side away from the anti-corrosion lining.

[0012] By adopting the above technical solution, the waterproof outer layer with a designed expansion can prevent leaked rainwater from adhering to the surface of the waterproof outer layer and then contacting the power supply node.

At the same time, the counterweight ball applies force to the movable sleeve through the traction rope under the action of the rotating centrifugal force, so that the movable sleeve overcomes the elastic force of the abutment spring and slides toward the side of the fixed frame, thereby making the sealing strip stop blocking the air hole and completing the opening of the air hole.

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The embodiments of the present application disclose a waterproof and anti-corrosion power supply node protection device and method for an agricultural-photovoltaic complementary electrical system.

[0035] In a first aspect, an embodiment of the present application discloses a waterproof and anti-corrosion power supply node protection device for an agricultural-photovoltaic complementary electrical system.

[0036] Reference Figure 1A waterproof and anti-corrosion power supply node protection device for an agricultural-photovoltaic complementary electrical system includes a protection box 1 and two outer protective covers 2. The protection box 1 is hollow, and two opposite sides of the protection box 1 are coaxially provided with through holes. The outer protective covers 2 are arranged through the through holes, and the outer protective covers 2 are clamped with the hole walls of the through holes by interference fit. The outer protective covers 2 are sleeved on the outer peripheral side of the power pipeline and located at both ends of the power supply node. After the through holes are blocked by the outer protective covers 2, a relatively sealed protection space can be formed inside the protection box 1, thereby reducing the erosion of the power supply node by rain, wind and frost, and extending the service life of the power supply node.

[0037] Reference Figure 2 Specifically, the protection box 1 includes a hollow box body 11 and two water intercepting grooves 12. The box body 11 is fixed with the outer protective cover 2 by clamping. The two water intercepting grooves 12 are respectively arranged near the two penetration holes. The water intercepting grooves 12 are welded and fixed to the box body 11 to form a water intercepting cavity. The outer protective cover 2 is arranged through the water intercepting grooves 12. When external rainwater invades through the gap between the box body 11 and the outer protective cover 2, it will converge into the water intercepting grooves 12 to prevent the infiltrated rainwater from directly contacting the power supply node.

[0038] Reference Figure 3 Furthermore, the outer protective cover 2 includes a waterproof outer layer 21, an anti-corrosion lining 22 and a sealing connection layer 23. The waterproof outer layer 21 is clamped with the protective box 1, and the inner side of the waterproof outer layer 21 is connected to the anti-corrosion lining 22. The side of the anti-corrosion lining 22 away from the waterproof outer layer 21 is connected to the sealing connection layer 23. The sealing connection layer 23 is used to connect with the power pipeline. The waterproof outer shell can prevent rainwater from affecting the anti-corrosion lining 22. The anti-corrosion lining 22 can prevent corrosive substances from directly contacting the power supply node. The sealing connection layer 23 can ensure the sealing of the connection between the power pipeline and the anti-corrosion lining 22. In order to prevent leaked rainwater from adhering to the surface of the waterproof outer layer 21 and then contacting the power supply node, the end of the waterproof outer layer 21 close to the power supply node is expanded toward the side away from the anti-corrosion lining 22, so that the distance between the expanded section of the waterproof outer layer 21 and the power pipeline gradually increases.

[0039] Reference Figure 4 The rainwater that penetrates in will evaporate in the protection box 1 to form water vapor and affect the power supply node. In order to discharge the moisture in the protection box 1 in time, the waterproof and anti-corrosion power supply node protection device of the agricultural-photovoltaic complementary electrical system also includes a fixed frame 4, a rotating ring 5, a movable sleeve 6, and a blower fan blade 62. The fixed frame 4 is fixedly connected to the power supply node through an insulating material, the rotating ring 5 is rotatably connected to the fixed frame 4, and the rotation axis of the rotating ring 5 is coaxially arranged with the outer protective sleeve 2.

[0040] Reference Figure 4There are two movable sleeves 6, which are respectively located on opposite sides of the power supply node. The movable sleeve 6 is slidably connected to the rotating ring 5 through a sliding rod, and the sliding direction of the movable sleeve 6 is consistent with the rotation axis of the rotating ring 5. The number of the blower blades 62 is consistent with the number of the movable sleeves 6. The blower blades 62 are coaxially screwed with the movable sleeves 6, and a hole for the power pipeline to pass through is formed on the blower blades 62.

[0041] Reference Figure 4 In order to facilitate the discharge of moisture inside the protection box 1, air holes 3 are provided at corresponding positions on the water intercepting groove 12 and the box body 11. In order to reduce the possibility of rainwater directly entering the inner cavity of the box body 11 through the air holes 3, a conical cover 13 is welded and fixed on the outer side of the box body 11. The water intercepting cavity is connected to the inner cavity of the conical cover 13 through the air holes 3. The outer protective sleeve 2 is arranged through the conical cover 13, and the inner diameter of the conical cover 13 gradually decreases toward the side away from the power supply node. In addition, a sealing strip 61 is screwed to the side of the movable sleeve 6 away from the fixed frame 4. After the sealing strip 61 slides toward the side of the water intercepting groove 12, it can abut against the water intercepting groove 12 and block the air holes 3. It is worth mentioning that there is a gap for gas to pass through between the sealing strips 61, or an air hole is provided on the sealing strip 61.

[0042] Reference Figure 4 and Figure 5 In order to drive the rotating ring 5 to rotate, and then drive the movable sleeve 6 to rotate through the rotating ring 5, so as to realize the rotation of the blower blades 62, the waterproof and anti-corrosion power supply node protection device of the agricultural-photovoltaic complementary electrical system also includes a driving unit 7, which is connected to the fixed frame 4, and the driving unit 7 is connected to the rotating ring 5 to realize the driving of the rotating ring 5.

[0043] Reference Figure 5 Specifically, the driving unit 7 includes a driving motor 71 and a friction wheel 72. The driving motor 71 is bolted to the fixing frame 4, and the axial direction of the output shaft of the driving motor 71 is consistent with the rotation axis of the rotating ring 5. The friction wheel 72 is coaxially connected to the driving motor 71, and the friction wheel 72 abuts against the inner side of the rotating ring 5. When the friction wheel 72 rotates, the rotating ring 5 is driven to rotate by friction force.

[0044] Reference Figure 5 In order to quickly discharge the moisture in the box 11 through the air vent 3 when the fan blades 62 are working, the waterproof and anti-corrosion power supply node protection device of the agricultural-photovoltaic complementary electrical system also includes a sliding unit 8, which is connected to the movable sleeve 6, and the sliding unit 8 is connected to the rotating ring 5, and is used to drive the movable sleeve 6 to slide along the axial direction of the rotating ring 5.

[0045] Reference Figure 5Specifically, the sliding unit 8 includes multiple abutment springs 81 and multiple counterweight balls 82. The abutment spring 81 is sleeved on the sliding rod, and one end of the abutment spring 81 is welded to the rotating ring 5, and the other end is welded to the end of the moving sleeve 6 away from the sealing strip 61. Two traction ropes 83 are screwed to the counterweight ball 82, and the two traction ropes 83 are screwed to the two moving sleeves 6 respectively; the driving unit 7 drives the rotating ring 5 to rotate, and the rotating ring 5 drives the moving sleeve 6 and the fan blade 62 to rotate while the rotating ring 5 rotates. At the same time, the counterweight ball 82 applies force to the moving sleeve 6 through the traction rope 83 under the action of the centrifugal force of rotation, so that the moving sleeve 6 overcomes the elastic force of the abutment spring 81 and slides toward the side of the fixed frame 4, thereby making the sealing strip 61 stop blocking the air vent 3 and completing the opening of the air vent 3. As the fan blade 62 rotates, the moisture inside the protection box 1 is discharged through the air vent 3, thereby synchronously completing the movement of the sealing strip 61 and the rotation of the fan blade 62.

[0046] The implementation principle of a waterproof and anti-corrosion power supply node protection device for an agricultural-photovoltaic complementary electrical system in an embodiment of the present application is as follows: when the weather is clear, an external power supply provides electrical energy for the driving unit 7 to work, and the driving unit 7 drives the rotating ring 5 to rotate. The rotating ring 5 drives the movable sleeve 6 and the blower blades 62 to rotate while rotating. At the same time, the counterweight ball 82 applies force to the movable sleeve 6 through the traction rope 83 under the action of the rotating centrifugal force, so that the movable sleeve 6 overcomes the elastic force of the abutment spring 81 and slides toward the side of the fixed frame 4, thereby causing the sealing strip 61 to stop blocking the air hole 3 and complete the opening of the air hole 3. At this time, the inner cavity of the protection box 1 is connected to the outside world, and because the blower blades 62 rotate with the rotation of the movable sleeve 6, the blower blades 62 exchange gas between the moisture in the inner cavity of the protection box 1 containing a large amount of moisture and the dry air with a low moisture content in the outside world, thereby reducing moisture. The corrosion time of steam on the protection node, after all the water is discharged, the driving unit 7 stops driving the rotating ring 5 to rotate, the sliding unit 8 drives the movable sleeve 6 to move, and the sealing strip 61 blocks the air vent 3 again; the protection box 1 can provide a closed protection space for accommodating the power supply node, and the outer protective sleeve 2 can protect the connecting pipelines at both ends of the power supply node. The rotation of the rotating ring 5 can be achieved through the cooperation of the fixed frame 4, the rotating ring 5 and the driving unit 7. The rotating ring 5 can drive the movable sleeve 6 to rotate and then drive the fan blades 62 to rotate, so as to discharge the moisture in the inner cavity of the protection box 1 and reduce the impact of rainwater leaking into the protection box 1 and staying for a long time on the life of the power supply node; the sliding unit 8 can realize the movement of the movable sleeve 6, and then drive the sealing strip 61 to move to achieve the closing and opening of the air vent 3.

[0049] Specifically, the sliding unit 8 includes A plurality of abutment springs 81, one end of each abutment spring 81 is connected to the rotating ring 5, and the other end is connected to an end of the movable sleeve 6 away from the sealing strip 61; A plurality of counterweight balls 82, each counterweight ball 82 is connected to two traction ropes 83, and the two traction ropes 83 are respectively connected to the two moving sleeves 6; At this time, the driving unit 7 drives the rotating ring 5 to rotate, and the weighted ball 82, under the action of centrifugal force, causes the movable sleeve 6 to overcome the elastic force of the abutting spring 81 through the traction rope 83 to slide toward the fixing frame 4 to release the air vent 3.
