[0020] A schematic photovoltaic-driven soil remediation device, referring to Figures 1 to 3 , A photovoltaic-driven soil remediation device according to a preferred embodiment of the present invention includes a tree body member 10, a piercing member 20, and a plurality of side spiking rods 30.

[0021] Specifically, asFigure 1 As shown, the tree member 10 includes a main trunk portion 101 and a plurality of tree branch portions 102. A plurality of photovoltaic panels 1021 are provided on each tree branch portion 102. A first accommodation cavity 1011 is formed inside the main trunk portion 101. A battery 103, a water pump 104, a chemical agent tank 105, and a lifting drive device 106 are provided inside the first accommodation cavity 1011. The chemical agent tank 105 stores a liquid soil heavy metal remediation agent. The liquid soil heavy metal remediation agent includes, but is not limited to, the liquid for dissolving heavy metal ions disclosed in the patent document (CN209206028U). The battery 103 is electrically connected to the photovoltaic panels 1021, the water pump 104, and the lifting drive device 106. Additionally, the piercing member 20 is fixedly connected to the bottom of the tree member 10. The piercing member 20 has a second accommodation cavity 201. A lifting member 202 is arranged to be lifted and lowered inside the second accommodation cavity 201. The lifting member 202 is connected to the push rod of the lifting drive device 106. The lifting member 202 has a plurality of cone portions 2021 and a water inlet channel 2022. A plurality of liquid injection holes 2023 arranged in an annular array are formed at the top of each cone portion 2021. The water inlet channel 2022 communicates with each liquid injection hole 2023. The water inlet of the water pump 104 is communicated with the outlet of the chemical agent tank 105. The water outlet of the water pump 104 is communicated with the water inlet channel 2022. Additionally, a side piercing rod 30 is provided on the side of each cone portion 2021. The side piercing rods 30 correspond to the liquid injection holes 2023 one by one. The side piercing rods 30 are horizontally arranged and slidably arranged on the piercing member 20. When the lifting member 202 moves up and down, the piercing member 20 is placed inside the second accommodation cavity 201 or extends a predetermined distance from the side of the piercing member 20. Each side piercing rod 30 has a liquid flow channel 301. A plurality of liquid discharge holes 302 are formed on the liquid flow channel 301. And when the lifting member 202 moves downward to a predetermined distance, each liquid injection hole 2023 communicates with the liquid flow channel 301 of the corresponding side piercing rod 30.

[0022] It should be noted that by providing the tree member 10 on the piercing member 20, it is ensured that the piercing member 20 can be inserted into the soil to be remediated for a long time within a period. At the same time, it plays a role in being beautiful and imitating a tree. By providing the photovoltaic panels 1021 on the tree branch portions 102, it provides an energy supply for the battery 103 placed inside the main trunk portion, and further provides a power source for the water pump 104 and the lifting drive device 106, providing conditions for injecting the soil remediation liquid into the soil.

[0023] In addition, it should be emphasized that after the piercing member 20 pierces into the soil, by actuating the push rod of the lifting drive device 106, the lifting member 202 moves downward by a predetermined distance. Also, because the side piercing rods 30 are in contact with the lifting member 202, when the lifting member 202 moves downward, each side piercing rod 30 receives a horizontal force, causing each side piercing rod 30 to extend out of the side wall of the piercing member 20 and pierce into the soil outside the piercing member 20. It should also be noted that when the conical portions 2021 move towards each other to a predetermined position, the side piercing rods 30 are aligned with the liquid injection holes 2023, and the liquid flow channels 301 are communicated with the liquid injection holes 2023. Subsequently, by actuating the water pump 104, the liquid soil remediation agent in the chemical agent tank 105 flows into the water inlet channel 2022, the liquid injection holes 2023, the liquid flow channels 301 in sequence, and is discharged from the liquid discharge holes 302 and infiltrates into the soil, thereby reducing the heavy metal content in the soil and achieving soil remediation. In addition, when more liquid soil heavy metal remediation agent in the chemical agent tank 105 is used, the disassembly plate on the main trunk portion 101 above the ground can be opened to replenish the liquid soil heavy metal remediation agent into the chemical agent tank 105.

[0024] In summary, by providing the tree body member 10 on the piercing member 20, the soil remediation device can perform long-term solution perfusion at a certain position of the soil, reducing the heavy metal content at the corresponding position of the soil. And during this soil remediation process, since the tree body member 10 is designed to imitate a tree, the aesthetics is also improved. In addition, after the piercing member 20 pierces into the soil, by causing the side piercing rods 30 to extend out of the side wall of the piercing member 20 and connecting the liquid flow channels 301 in the side piercing rods 30 with the chemical agent tank 105, the liquid soil heavy metal remediation agent can penetrate the soil in a wider range. Compared with the prior art, it has the advantages of being long-term fixed to the soil, beautiful, and capable of performing more long-term and wider-range soil remediation.

[0025] Furthermore, to enable the side piercing rods 30 to extend into the liquid injection holes 2023 by a predetermined distance after being aligned with the liquid injection holes 2023, as Figure 2 shown, the photovoltaic-driven soil remediation device further includes a plurality of first springs 303. Each side piercing rod 30 is sleeved with a first spring 303. The two ends of the first spring 303 are respectively connected to the side piercing rod 30 and the wall of the second accommodation cavity 201. Each end of the liquid injection hole 2023 facing away from the water inlet channel 2022 has a counterbore portion 20231. When the side piercing rod 30 is aligned with the liquid injection hole 2023, the side piercing rod 30 extends into the counterbore portion 20231 by a predetermined distance under the elastic force of the first spring 303.

[0026] It should be emphasized that the end of the side thorns rod 30 has the liquid discharge hole 302. If the end of the side thorns rod 30 is in a fitting state with the soil after the side thorns rod 30 penetrates into the soil to a predetermined depth, the liquid soil heavy metal remediator will be blocked by the soil and the infiltration speed will be slow. In view of this, in the present invention, by providing the first spring 303 and the sunken hole part 20231, when the side thorns rod 30 is opposite to the liquid injection hole 2023, the side thorns rod 30 is retracted a predetermined distance towards the sunken hole part 20231, and a space is formed between the end of the side thorns rod 30 and the soil, so as to facilitate the more rapid penetration of the liquid soil heavy metal remediator into the soil.

[0027] It should also be emphasized that when the side thorns rod 30 does not penetrate to the predetermined position in the soil, if the soil enters the liquid flow channel 301 along the liquid discharge hole 302 and blocks the liquid discharge hole 302, it will also affect the liquid discharge. In view of this, in the present invention, as Figure 3 shown, each orifice of the liquid discharge hole 302 has a spring piece groove, and a spring piece 3021 is arranged in the spring piece groove. One end of the spring piece 3021 is fixedly connected with the side thorns rod 30, and the spring piece 3021 closes the liquid discharge hole 302 under normal conditions.

[0028] It should be noted that by providing the spring piece 3021 that can only be turned outwards unidirectionally, during the process of the side thorns rod 30 penetrating into the soil, that is, during the process when the water pump 104 has not sent the liquid soil heavy metal remediator into the liquid flow channel 301, the entry and blockage of the liquid discharge hole 302 by the soil are effectively avoided. After the liquid soil heavy metal remediator flows into the liquid flow channel 301, the spring piece is slightly turned outwards under the impact of the water flow, and the liquid soil heavy metal remediator infiltrates into the soil.

[0029] It should also be emphasized that since there are multiple cone parts 2021 on the piercing member 20 in the height direction, the less liquid soil heavy metal remediator flows into the side thorns rod 30 on the cone part 2021 farther away from the water pump 104. In view of this, in the present invention, as Figure 3As shown, each of the side piercing rods 30 includes a main rod body 304, a sleeve rod portion 305 and a flow limiting plug 306, wherein the main rod body 304 has a first chamber 3041, and the sleeve rod portion 305 has a second chamber 3042. The sleeve rod portion 305 is sleeved on one end of the main rod body 304 away from the cone portion 2021, and the first chamber 3041 is connected to the second chamber 3042 to form the liquid flow channel 301, and the flow limiting plug 306 is slidably arranged in the first chamber 3041, and the sleeve rod portion 305 is sleeved on the end of the main rod body 304 away from the cone portion 2021. 05 also has a protrusion 3051, which extends from the center of the second chamber 3042 toward the cone portion 2021 and extends into the first chamber 3041 by a predetermined distance. The flow limiting plug 306 has a center hole 3061, and the aperture of the center hole 3061 is larger than the radial dimension of the protrusion 3051. The first chamber 3041 has a shoulder portion, and a second spring 307 is provided on the shoulder portion. The drainage hole 302 is located on the side wall and the bottom wall of the second chamber 3042.

[0030] It should be noted that when the liquid soil heavy metal remediation agent flows into the first chamber 3041, it will pass through the center hole 3061 and flow to the second chamber 3042, but at the same time, the liquid soil heavy metal remediation agent will also impact the body of the limiting plug 306, and cause the limiting plug 306 to move toward the direction of the boss 3051, and at a certain moment, the limiting plug 306 presses the second spring 307 and causes the boss 3051 to approach or extend into the center hole 3061. As a result, the liquid soil heavy metal remediation agent can only flow into the second chamber 3042 along the area between the side wall of the boss 3051 and the hole wall of the center hole 3061, thereby preventing the side thorn rod 30 on the upper cone portion 2021 from flowing out too much liquid soil heavy metal remediation agent, and the liquid soil heavy metal remediation agent is difficult to flow into the side thorn rod 30 on the bottom of the cone portion 2021.

[0031] In addition, if Figure 3 As shown, the diameter of the drainage hole 302 located on the bottom wall of the second chamber 3042 is smaller than the diameter of the drainage hole 302 located on the side wall of the second chamber 3042 .

[0032] In addition, in order to facilitate sufficient irrigation of various parts of the soil, the projections of the side thorn rods 30 on the two adjacent cone parts 2021 in the height direction do not overlap.

[0033] In addition, in order to make full use of the space in the first accommodating cavity 1011, Figure 1 As shown, the medicine box 105 is cylindrical, and the medicine box 105 is sleeved on the outside of the lifting drive device 106.

[0034] In summary, the photovoltaic-driven soil remediation device based on the embodiments of the present application is elucidated, which provides advantages such as being permanently fixed to the soil for a long time, being aesthetically pleasing, and being able to perform soil remediation for a longer period and in a wider range.

[0035] It is worth mentioning that in the embodiments of the present application, the photovoltaic-driven soil remediation device has a simple structure, does not involve complex manufacturing processes and expensive materials, and has high economic efficiency. At the same time, for manufacturers, the photovoltaic-driven soil remediation device provided by the present application is easy to produce and has low costs, which is more conducive to controlling production costs and further conducive to the promotion and use of the product.

[0036] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The object of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and without departing from this principle, the embodiments of the present invention can have any deformation or modification.
