The storage pond can adjust the outflow to control the water level to meet the urban water demand in different seasons and periods; when water passes through the pond, some impurities in the water will precipitate at the bottom of the pond, which can improve the water quality; store a large amount of water in the rainy season or other peak water flow periods, reduce the flooding of rivers or streams, prevent floods, and at the same time can provide continuous water resources for the dry season; provide a good ecological environment, attract and protect diverse biological communities, maintain ecological balance, and serve as part of the natural landscape.

[0003] The storage pond occupies a large area. To make full use of geographical resources, it is usually combined with photovoltaic power generation. Photovoltaic power generation requires driving photovoltaic pipe piles into the soil layer at the bottom of the storage pond.

Detailed Embodiments

[0035] Next, in combination with the drawings and specific embodiments, the present invention will be further described. It should be noted that, on the premise of no conflict, any combination of the following described embodiments or technical features can form a new embodiment.

[0036] Embodiment 1:

[0037] Please combine with Figures 1-7 For the active pressure anti-seepage device for the photovoltaic pipe pile of this embodiment to penetrate the anti-seepage membrane, it includes a soil bin 1, an equipment bin 2, and an airbag bin 3 arranged in sequence. A pressure-dividing bin 4 for inflating the soil is fixedly connected to the top of the equipment bin 2, and the outer circle of the pressure-dividing bin 4 is fixedly connected to the soil bin 1. A channel 5 communicating with the equipment bin 2 penetrates through the soil bin 1. An adjusting assembly 6 connecting the soil bin 1 and the equipment bin 2 is installed in the channel 5. An inflation control assembly 10 is fixedly connected to the top of the adjusting assembly 6. An airbag 11 is arranged in the airbag bin 3. The soil bin 1, the equipment bin 2, the airbag bin 3, and the pressure-dividing bin 4 are all hollow annular structures. A lifting hook for hoisting is welded to the top of the soil bin 1;

[0038] The adjusting assembly 6 includes a lifting mechanism 7 fixedly connected to the inner side wall of the top of the soil bin 1 and the inner side wall of the bottom of the equipment bin 2, and a support plate 9 for carrying the inflation control assembly 10. A lifting and stabilizing mechanism 8 slidably connected to the lifting mechanism 7 is fixedly connected to the outside of the support plate 9;

[0039] The lifting mechanism 7 includes two groups of movable plates 71 moving in the vertical direction, a limiting plate 72 fixedly connected between the two groups of movable plates 71, and a limiting channel 73 penetrating through the limiting plate 72. The limiting channel 73 is slidably connected to the lifting and stabilizing mechanism 8, and the limiting channel 73 is used to guide and limit the movement of the lifting and stabilizing mechanism 8. A screw rod 75 for driving its lifting is threadedly sleeved on one of the movable plates 71;

[0040] The lifting and stabilizing mechanism 8 includes a support rod 81 fixedly connected to the support plate 9 and a cross bar 51 arranged on one side of the movable plate 71. The support rod 81 is rotatably sleeved with a deflecting rod one 82 and a deflecting rod two 84. The other end of the deflecting rod one 82 is fixedly connected to a driven rod one 83, and the other end of the deflecting rod two 84 is fixedly connected to a driven rod two 85. Both the driven rod one 83 and the driven rod two 85 are slidably connected to the limiting channel 73. A first groove plate 52 for adjusting the state of the driven rod one 83 and a second groove plate 54 for adjusting the state of the driven rod two 85 are fixedly connected to the bottom of the cross bar 51.

[0041] The bottom of the screw rod 75 is fixedly connected to a motor fixedly connected to the inner side wall of the bottom of the equipment bin 2. The outer circle of the screw rod 75 is movably sleeved with a support frame fixedly connected to the equipment bin 2. The top of the screw rod 75 is fixedly connected to an adjusting rod rotatably sleeved on the top of the soil bin 1. One end of the adjusting rod extending out of the top of the soil bin 1 is provided with an operation groove with a regular polygon structure. When the battery power runs out, a handle with a cross-section consistent with the operation groove is used to extend into the operation groove and turn the handle to manually drive the screw rod 75 to rotate, so as to manually drive the lifting mechanism 7 to perform lifting operations.

[0042] The movable plate 71 is slidably sleeved with a guide rod 74. The top of the guide rod 74 is fixedly connected to the inner side wall of the top of the soil bin 1, and the bottom of the guide rod 74 is fixedly connected to the inner side wall of the bottom of the equipment bin 2. One side of the opening of the channel 5 is hinged with a cover plate. When the motor is started, the screw rod 75 rotates, so that the movable plate 71 moves vertically under the guidance of the guide rod 74, realizing the primary lifting operation of the inflation control assembly 10 on the support plate 9 by the lifting mechanism 7, and lifting the inflation control assembly 10 into the soil bin 1 along the equipment bin 2.

[0043] The first trough plate 52 includes an inclined section fixedly connected to the bottom of the cross bar 51 and a holding section arranged at the bottom of the inclined section and fixedly connected to the inner side wall of the bottom of the equipment bin 2. The first trough plate 52 is provided with an adjustment groove 53 distributed along the direction from the inclined section to the holding section. The second trough plate 54 has the same structure as the first trough plate 52. The cross bar 51 is fixedly connected to the inner side wall of the top of the soil bin 1. When the inflation control assembly 10 is lifted upward by the lifting mechanism 7 and the movable plate 71 rises, four groups of lifting and stabilizing mechanisms 8 arranged outside the support plate 9 form a triangular structure during the rising process on the one hand, making the support plate 9 rise smoothly without deflection, and on the other hand, when rising, the inflation control assembly 10 can be extended from the channel 5 at the top of the soil bin 1 to the top of the inflation control assembly 10, realizing the secondary lifting of the inflation control assembly 10, while improving the connection strength and stability of the overall structure, and changing the problem of insufficient lifting stroke caused by the defects of the traditional lifting structure, so as to facilitate the operator to repair and replace the inflation control assembly 10 at the top of the soil bin 1.

[0044] When lifting, when the movable plate 71 rises, first, the limiting plate 72 moves upward, and the driven rod one 83 and the driven rod two 85 on the limiting channel 73 located on the limiting plate 72 also move upward accordingly. Then, the distance between the driven rod one 83 and the driven rod two 85 is adjusted by using the adjustment groove 53 on the lifting and stabilizing mechanism 8. During the rising stage, under the action of the limiting channel 73, a triangular structure is formed between the driven rod one 83 and the driven rod two 85 and the deflecting rod one 82 and the deflecting rod two 84, so that the position of the top support rod 81 does not deflect when rising. On the one hand, the four groups of support rods 81 rise smoothly, and on the other hand, by pushing the deflecting rod one 82 and the deflecting rod two 84 to deflect, the support rod 81 is driven to move upward relative to the movable plate 71 when the movable plate 71 rises, ensuring that the support plate 9 performs a secondary rise when rising with the lifting mechanism 7, improving the lifting stroke and stability.

[0045] At the top of the airbag 11, there is a supplementary air pipe 13 that extends upward and protrudes from the outer wall of the soil bin 1. A pressure sensor is installed on the supplementary air pipe 13. At one end of the supplementary air pipe 13 that protrudes from the soil bin 1, a valve and an air pipe joint for inflation are installed. The pressure sensor is used to detect the air pressure of the airbag 11 during use, and at the same time, it can be supplemented from the outside of the soil bin 1 using the air pipe joint to ensure the overall service life of the air pressure boosting device of the airbag 11; the soil bin 1 is provided with a humidity sensor 14 for detecting the humidity of the soil filled inside the soil bin 1 to realize the air supply of the airbag 11 to the pressure dividing bin 4. The humidity sensor 14 is a buried soil humidity sensor, and the number of humidity sensors 14 is two and they are distributed in sequence along the vertical direction.

[0046] At the top of the pressure dividing bin 4, there are air holes communicating with its inner cavity. Geotextiles are laid on the top and the inner ring of the pressure dividing bin 4. The air flow for inflating the soil in the pressure dividing bin 4 is discharged upward into the soil along the air holes, and the geotextiles are used to protect the air holes to prevent sediment and gravel in the soil from entering the pressure dividing bin 4 along the air holes. At the same time, the geotextile arranged on the inner ring of the pressure dividing bin 4 abuts against the pipe pile to prevent the soil from overflowing downward from the gap between the inner ring of the pressure dividing bin 4 and the outer ring of the pipe pile.

[0047] The soil bin 1 includes a top plate and a bottom plate with a ring structure, an inner closed plate with a ring structure fixed between the inner rings of the top plate and the bottom plate, and an outer closed plate with a ring structure fixed between the outer rings of the top plate and the bottom plate. Reinforcing ribs are fixedly connected between the top plate and the bottom plate and the inner closed plate and the outer closed plate. The reinforcing ribs can improve the overall strength of the soil bin 1, the equipment bin 2, the airbag bin 3, and the pressure dividing bin 4, and prevent the soil bin 1, the equipment bin 2, the airbag bin 3, and the pressure dividing bin 4 from deforming and being damaged during long-term use. The structures of the soil bin 1, the equipment bin 2, the airbag bin 3, and the pressure dividing bin 4 are the same. Geotextiles and anti-seepage membranes are laid on the bottom of the airbag bin 3 from top to bottom in sequence, and geotextiles are filled between the inner ring of the airbag bin 3 and the outer ring of the photovoltaic pipe pile.

[0048] The distance between two adjacent groups of support rods 81 on the same side of the limiting plate 72 is greater than twice the length of the first deflecting rod 82.

[0049] Embodiment 2:

[0050] Based on Embodiment 1, the further improvement in this embodiment is that the inflation control assembly 10 includes a control box fixedly connected to the support plate 9. An air inflator, a battery compartment, a controller, and a wireless transceiver device are arranged in the control box. A storage battery is placed in the battery compartment. The output end of the air inflator is connected to an air pipe one communicating with the pressure dividing bin 4, and the input end of the air inflator is connected to an air pipe two connected to the airbag 11. The air inflator is used to transport the gas in the airbag 11 to the pressure dividing bin 4; a data interface and a switch are installed on the control box. The controller is connected to the motor, the humidity sensor 14, the storage battery, the air inflator, the pressure sensor, and the wireless transceiver device.

[0051] Example 3:

[0052] A method for using an active pressure anti-seepage device for a photovoltaic pipe pile to penetrate an anti-seepage membrane includes the following steps:

[0053] Step S1, design and assembly production of the active pressure anti-seepage device:

[0054] Determine the size of the active pressure anti-seepage device according to the landfill depth and diameter of the photovoltaic pipe pile, and complete the production and assembly operations of the active pressure anti-seepage device based on the size design drawing;

[0055] Step S2, reserve a space for installing the active pressure anti-seepage device outside the photovoltaic pipe pile, and use a hoisting device to hoist the active pressure anti-seepage device to the outside of the photovoltaic pipe pile to complete the installation operation of the active pressure anti-seepage device;

[0056] Step S3, fill the inside of the active pressure anti-seepage device with soil for anti-seepage, and use the active pressure anti-seepage device to perform a pressure anti-seepage operation on the photovoltaic pipe pile.

[0057] When performing active pressure anti-seepage, add dry cohesive soil to the soil bin 1 in the device and inflate the airbag 11 through the air pipe joint on the air supply pipe 13 located on the soil bin 1. When the pressure detected by the pressure sensor reaches the set value, it indicates that the airbag 11 is fully inflated;

[0058] Since the flow rate of water seepage satisfies the following formula;

[0059] ;

[0060] where Q is the flow rate of water seepage per unit time ( ); k is the permeability coefficient of the soil ( ); A is the cross-sectional area of the flowing water ( ); is the total head difference ( ); L is the length of the seepage path ( );

[0061] The above formula shows that the principle of seepage is caused by the head difference. After the internal pressure of the cohesive soil in the soil bin 1 is pressurized to be greater than the head difference, the seepage path can be changed, that is: P> h, where P is the pressure of the pressurized cohesive soil (Pa); is the total head difference ( ), change the downward seepage path to upward seepage, and discharge the seepage water upward to meet the anti-seepage requirements of the project for the connection of the pipe piles.

[0062] When the device is installed and water seepage starts at the joint of the pipe piles during rainfall or other conditions, since the cohesive soil in the soil bin 1 is in close contact with the pipe piles, the water seepage will only start from the cohesive soil in the soil bin 1; the seepage will cause the humidity of the cohesive soil to increase. When the humidity exceeds the warning value, the upper humidity sensor 14 will transmit the data to the controller. The water continues to seep downward in the cohesive soil. After the lower humidity sensor 14 also monitors that the humidity exceeds the warning value and feeds back the data to the controller, the controller will make the inflator start to work, and the gas in the airbag 11 will be filled into the pressure dividing bin 4 at the lower part of the soil bin 1 through the second air pipe and the first air pipe, and then enter the cohesive soil through the air holes at the upper part of the pressure dividing bin 4; at this time, the pressure in the cohesive soil changes due to the injection of gas. Because the seepage of water is due to the pressure difference, when the pressure in the lower part of the soil bin 1 is increased to increase the pressure in the cohesive soil, the pressure difference between the soil and the water surface is changed. When the pressure in the cohesive soil is greater than the pressure of the water on the cohesive soil, the seepage path of the water will change and it will seep from bottom to top, that is, the water is discharged upward from the cohesive soil to prevent the water from seeping in along the gap at the joint of the pipe piles;

[0063] After the rainfall stops or the water on the edge of the pipe pile dries up, because the water in the cohesive soil is discharged upward under pressure, the lower humidity sensor 14 should first monitor that the humidity of the cohesive soil is decreasing. When the humidity is lower than the normal value, the data will be transmitted to the controller; when the water seeps upward to the upper humidity sensor 14, after the upper humidity sensor 14 also monitors that the humidity is lower than the normal value and feeds back to the controller, the controller will turn off the inflator to reduce the loss of gas in the airbag 11 and extend the service time; the gas in the airbag 11 can be observed at any time by the air pressure sensor outside the soil bin 1. What the air pressure sensor shows is how much gas is left in the airbag 11. When the air pressure sensor shows that the air pressure is lower than the warning value, the airbag 11 can be directly inflated from the air pipe joint. After use, only need to regularly check whether the gas in the airbag 11 is sufficient and replenish it at any time.

[0064] This design utilizes components such as a soil bin, an equipment bin, an airbag bin, and a pressure-dividing bin installed outside the photovoltaic pipe pile. It adopts the method of supplying air to the soil upward to achieve the operation of active pressure anti-seepage, effectively avoiding the downward infiltration of water along the gap between the outside of the photovoltaic pipe pile and the anti-seepage membrane, solving the leakage problem at the connection where the photovoltaic pipe pile penetrates the anti-seepage membrane, enhancing the anti-seepage ability of the pool body such as the regulating pool where the anti-seepage membrane is laid, ensuring the normal operation of the regulating pool, and avoiding the occurrence of groundwater pollution and foundation settlement of surrounding buildings caused by the water leakage of the regulating pool. It effectively plays the role of the regulating pool in controlling non-point source pollution and urban floods; it uses a two-stage lifting method to lift the control air supply components completely stored inside the device upward to the top of the device, facilitating maintenance operators to perform replacement operations at the top of the device, increasing the lifting stroke, solving the problems of insufficient lifting stroke, complex structure, and more components of traditional lifting components, which lead to an increase in the overall weight of the device, and also improving the stability and operation smoothness of the overall device. When the power is exhausted, manual operation can be carried out for lifting and maintenance.

[0065] The above-mentioned implementation manners are only the preferred implementation manners of the present invention, and cannot be used to limit the scope of protection of the present invention. Any non-substantive changes and substitutions made by those skilled in the art on the basis of the present invention belong to the scope of protection required by the present invention.
