Description

Technical Field

[0001] The present invention relates to the technical field of embedded steel casings, and in particular to a photovoltaic pile embedded steel casing with a drainage function and a use method thereof. Background Art

[0002] During the construction of photovoltaic power stations, the stable installation of photovoltaic piles is a key link to ensure the safe and reliable operation of solar cell modules. During the installation of photovoltaic piles, the embedded casing can effectively protect the pile body, prevent it from being directly exposed to the environment and being corroded or damaged, and at the same time improve the stability and pull-out resistance of the pile body.

[0003] In order to prevent concrete or fill from entering the pre-buried casing during construction, and mud and dirt from entering the pre-buried casing when the lower roadbed is muddy, the bottom of the pre-buried casing is generally designed to be a closed structure. However, in areas with heavy rain, such as southern my country or coastal areas, after rain, some rainwater will flow into the pre-buried casing. Because the bottom of the pre-buried casing is closed, rainwater accumulates in the pre-buried casing. Although part of the rainwater will evaporate, there will be accumulated water in the pre-buried casing for a long time. The long-term residual accumulated water accelerates the corrosion of the spiral spikes. A Chinese patent with the announcement number CN114960304B discloses a railway embedded casing with drainage function, including a ceramic inner casing and a metal outer casing, the bottom end of the ceramic inner casing is formed with an end plate, the ceramic inner casing is inserted into the metal outer casing, the outer wall of the ceramic inner casing is formed with a plurality of arc-shaped convex rings, the notches on the convex rings overlap to form a vertical limit slot, the upper end of the ceramic inner casing is formed with a cylindrical head, the outer wall of the head is against the inner wall of the metal outer casing, and a countersunk hole connected to the inner hole of the ceramic inner casing is formed in the head; the metal outer casing The sleeve is formed with inwardly recessed vertical rib grooves, which are inserted into the limit slots of the ceramic inner sleeve. The metal outer sleeve is formed with a plurality of annular rib grooves connected with the vertical rib grooves, which are inserted into the grooves between adjacent convex rings on the ceramic inner sleeve. Although the above patent can drain water through leakage grooves and seepage grooves, it mainly relies on the gravity drainage mechanism. In actual situations, especially in scenarios with heavy rainfall or severe water accumulation, it may be difficult to quickly and effectively drain a large amount of accumulated water by relying solely on gravity drainage, which may easily lead to water retention and affect the drainage effect.

[0004] The present invention aims to solve the problems existing in the above-mentioned patents. To this end, a pre-buried steel casing of a photovoltaic pile with drainage function and a method of use are proposed, which can automatically blow out the accumulated water to prevent the accumulation of water and improve the drainage effect.

[0035] See also Figure 3 As shown, the air supply assembly includes a humidity sensor 9, an air supply pipe 91, an air pump 92 and a hose 93. The air supply pipe 91 is fixedly connected to the upper right side of the ceramic sleeve 2, the bottom end of the air supply pipe 91 is connected to the top right side of the hollow ring 4, the top of the air supply pipe 91 is connected to the hose 93, and the air pump 92 is installed at the tail end of the hose 93. A humidity sensor 9 is fixedly connected to the middle of the liquid accumulation frame 8. The humidity sensor 9 can monitor the humidity in the ceramic sleeve 2, and the humidity sensor 9 is electrically connected to the air pump 92.

[0036] See also Figure 4-Figure 7As shown, the drainage assembly includes a drainage frame 10, a driving assembly, a guide frame 104 and an L-shaped baffle 105. The drainage frame 10 is fixedly connected to the lower right part of the outer side of the metal shell 1. A water outlet is arranged at the bottom of the drainage frame 10. An L-shaped baffle 105 is slidably connected to the inner side of the drainage frame 10. The L-shaped baffle 105 corresponds to the water outlet of the drainage frame 10. The L-shaped baffle 105 can block the water outlet of the drainage frame 10. The drainage port of the effusion frame 8 is connected to the guide frame 104. The guide frame 104 is fixedly passed through the ceramic sleeve 2 and the right side of the metal shell 1 and is located in the drainage frame 10. The guide frame 104 can discharge water into the drainage frame 10. The right side of the bottom of the guide frame 104 is open. The L-shaped baffle 105 A driving assembly is arranged between the drainage frame 10 and the ceramic sleeve 2. When the driving assembly is in operation, the driving assembly can drive the L-shaped baffle 105 to move; the driving assembly includes a sliding rod 101, a contact rod 102 and a waist-shaped orifice plate 103. The waist-shaped orifice plates 103 are symmetrically fixed to the upper and lower sides of the left side surface of the L-shaped baffle 105. A sliding rod 101 is slidably connected between the top of the drainage frame 10 and the guide frame 104. The top of the sliding rod 101 slides through the right side of the top of the ceramic sleeve 2. Four contact rods 102 are fixed to the lower part of the sliding rod 101. The four contact rods 102 are respectively slidably connected to the inner sides of the four waist-shaped orifice plates 103. When the contact rod 102 moves, the contact rod 102 can drive the waist-shaped orifice plates 103 to move.

[0037] First, insert the device to the inner side of the ground at the designated position. If the metal shell 1 is inserted too long, the L-shaped baffle 105 blocks the water outlet of the drainage frame 10, which can prevent soil from entering the drainage frame 10 and affecting the water discharge effect, thereby ensuring smooth water discharge. When the metal shell 1 is inserted to the designated depth, stop pushing the device, and then use a tool to knock the slide bar 101, so that the slide bar 101 moves downward to drive the contact rod 102 to move downward, and the contact rod 102 moves downward to drive the waist-shaped orifice plate 103 to move leftward, and the waist-shaped orifice plate 103 moves leftward. The orifice plate 103 moves to the left, driving the L-shaped baffle plate 105 to move to the left. The L-shaped baffle plate 105 moves to the left and stops blocking the water outlet of the drainage frame 10, and stops hitting the sliding rod 101. Then the photovoltaic pile can be placed into the ceramic sleeve 2 through the annular plate 3. Since the top of the annular plate 3 is an inverted cone, the photovoltaic pile can be better placed in the ceramic sleeve 2, and the photovoltaic pile contacts the limit rod 7 during the placement process. The limit rod 7 can guide and limit the photovoltaic pile to prevent the photovoltaic pile from damaging the spiral plate 6, thereby ensuring the safety of the spiral plate 6. After the photovoltaic pile is placed, the humidity sensor 9 is started to monitor the humidity in the ceramic sleeve 2. When the humidity in the photovoltaic pile reaches the set maximum value, the humidity sensor 9 controls the air pump 92 to start through the control module. The air pump 92 discharges the air into the air supply pipe 91 through the hose 93. The air in the air supply pipe 91 is discharged into the hollow ring 4. The air in the hollow ring 4 is discharged into the nozzle 5. The nozzle 5 sprays the air on the spiral plate 6. The spiral plate 6 guides the air to form a cyclone. The air forming the cyclone affects the water in the ceramic sleeve 2. Blowing is performed so that water flows downwardly into the liquid accumulation frame 8 along the spiral plate 6. Since the bottom of the liquid accumulation frame 8 is inclined, the water in the liquid accumulation frame 8 is discharged into the guide frame 104, and the water in the guide frame 104 is discharged into the drainage frame 10. The drainage frame 10 discharges the water into the soil. Due to the function of the drainage frame 10, the drainage area can be expanded, so that the water can be discharged. This is repeated, and the accumulated water in the ceramic sleeve 2 can be continuously blown out to prevent the accumulation of water, thereby improving the drainage effect and ensuring the long-term stability and safety of the photovoltaic pile. When the humidity in the ceramic sleeve 2 reaches the standard value, the humidity sensor 9 controls the air pump 92 to turn off through the control module, and the air pump 92 stops discharging air into the hose 93, and the nozzle 5 also stops spraying air. In this way, whenever the humidity in the ceramic sleeve 2 reaches the set maximum value, the air pump 92 is started, and the nozzle 5 sprays air to blow the water out. When the device needs to be pulled out of the ground, first pull the sliding rod 101 upwards, the sliding rod 101 moves upwards to drive the contact rod 102 to move upwards, the contact rod 102 moves upwards to drive the waist-shaped hole plate 103 to move right and reset, the waist-shaped hole plate 103 moves right to drive the L-shaped baffle 105 to move right and reset, the L-shaped baffle 105 is reset to block the water outlet of the drainage frame 10, and then the photovoltaic pile is taken out of the ceramic sleeve 2, and then the device is taken out of the ground.

[0038] See also Figure 8-Figure 10 As shown, the pre-buried steel casing of the photovoltaic pile with drainage function also includes a sealing component installed between the ceramic casing 2 and the annular plate 3, the sealing component includes an elastic cover 11, a swing plate 111, an n-type rod 112, a hoop 113, an annular airbag 114 and a trigger component, the top of the ceramic casing 2 is fixedly connected with the elastic cover 11 along the circumferential direction, the elastic cover 11 can block water and impurities, the top of the ceramic casing 2 is evenly connected with six swing plates 111 at intervals along the circumferential direction, the six swing plates 111 are all located in the elastic cover 11, the swing plates 111 are in contact with the inner side of the elastic cover 11, the tops of the six swing plates 111 are rotatably connected with n-type rods 112, the inner sides of the six n-type rods 112 are fixedly connected to the upper part of the elastic cover 11, the upper part of the outer side of the elastic cover 11 is provided with a hoop 113, the hoop 113 is located between the six n-type rods 112, the upper part of the inner side of the annular plate 3 is fixedly connected with an annular airbag 114 along the circumferential direction, when the annular When the annular airbag 114 expands, the annular airbag 114 can fill the gap between the annular plate 3 and the photovoltaic pile. A trigger component is arranged between the annular airbag 114 and the swing plate 111. When the trigger component is in operation, the trigger component can discharge air into the annular airbag 114; the trigger component includes a U-shaped plate 115, a cylinder body 116, a piston rod 117, a connecting spring 118 and a connecting pipe 119. The lower parts of the six swing plates 111 that are close to each other are symmetrically fixed with U-shaped plates 115, and six cylinder bodies 116 are fixedly connected to the upper part of the annular plate 3 at uniform intervals along the circumferential direction. The lower parts of the six cylinder bodies 116 are connected with connecting pipes 119, and the tail ends of the connecting pipes 119 are connected to the annular airbag 114. The piston rod 117 is slidably connected to the inner side of the cylinder body 116. The upper part of the piston rod 117 is slidably connected to the inner side of the U-shaped plate 115, and a connecting spring 118 is connected between the bottom end of the piston rod 117 and the bottom of the cylinder body 116.

[0039] When the photovoltaic pile is inserted into the ceramic sleeve 2, the photovoltaic pile is between the annular airbag 114 and the elastic cover 11, and then the clamp 113 is twisted to tighten. The tightening of the clamp 113 drives the upper part of the elastic cover 11 to swing inward, and the upper part of the elastic cover 11 swings inward to contact the outer wall of the photovoltaic pile. The elastic cover 11 seals the photovoltaic pile and the ceramic sleeve 2. The upper part of the elastic cover 11 swings inward, drives the n-shaped rod 112 to swing inward, and the n-shaped rod 112 swings inward to drive the swing plate 111 to swing inward. The swing plate 111 swings inward to drive the U-shaped plate 115 to swing inward, and the U-shaped plate 115 swings inward to drive the piston rod 117 moves downward, the connecting spring 118 is compressed, and the piston rod 117 moves downward to push the air in the cylinder 116 into the connecting pipe 119. The air in the connecting pipe 119 is discharged into the annular airbag 114. The discharge of air causes the annular airbag 114 to expand. The annular airbag 114 expands and contacts the photovoltaic pile. The annular airbag 114 further seals the photovoltaic pile and the ceramic sleeve 2, thereby improving the sealing effect. When the photovoltaic pile is in use, the elastic cover 11 and the annular airbag 114 can prevent water and impurities from entering the ceramic sleeve and corroding the photovoltaic pile, thereby ensuring the safety of the photovoltaic pile. When the device needs to be taken out of the ground, first twist the clamp 113 to loosen it, and the clamp 113 stops locking the upper part of the elastic cover 11. Due to the action of the connecting spring 118, the piston rod 117 moves upward through the connecting pipe 119 to draw the air in the annular airbag 114 back into the cylinder 116. As the air is drawn out, the annular airbag 114 shrinks and breaks away from the photovoltaic pile. At the same time, the piston rod 117 moves upward through the U-shaped plate 115 to drive the swing plate 111 to swing outward and reset. The swing plate 111 swings outward and resets through the n-shaped rod 112. The reset of the n-shaped rod 112 drives the upper part of the elastic cover 11 to swing outward and reset. In this way, water and impurities can be further prevented from entering the ceramic sleeve 2 from the outside to cause corrosion, thereby improving the safety of the photovoltaic pile and the ceramic sleeve 2.

[0040] See also Fig.11 As shown, the pre-buried steel casing of the photovoltaic pile with drainage function also includes a heating wire 12. The heating wire 12 is installed on the inner side of the hollow ring 4. When the heating wire 12 is started, the heating wire 12 can heat the air in the hollow ring 4. The heating wire 12 is electrically connected to the humidity sensor 9 through the control module.

[0041] When the humidity sensor 9 starts the air pump 92 through the control module, the air is discharged into the hollow ring 4. At the same time, the humidity sensor 9 also starts the heating wire 12, and the heating wire 12 heats the hollow ring 4, so that the air is heated into hot air, and the hot air is discharged into the nozzle 5. The nozzle 5 discharges the hot air into the ceramic sleeve 2. The hot air blows the water on the inner wall of the ceramic sleeve 2, and the hot air can also dry the ceramic sleeve 2, making the ceramic sleeve 2 drier. When the ceramic sleeve 2 is dry, the humidity sensor 9 controls the air pump 92 and the heating wire 12 to be turned off through the control module. In this way, the drying inside the ceramic sleeve 2 can be further improved to ensure the use effect of the ceramic sleeve 2.

[0042] The embodiment provides a method for using a pre-buried steel casing of a photovoltaic pile with a drainage function, comprising the following steps:

[0044] S2, drainage. When the humidity sensor 9 detects that the humidity in the ceramic sleeve 2 reaches the maximum value, the humidity sensor 9 controls the air pump 92 to start through the control module.
