[0002] In recent years, in order to solve the problem of urban waterlogging and control non-point source pollution, major cities in my country have built storage ponds one after another. Storage ponds can control the water level by adjusting the outflow to meet the water demand of cities in different seasons and time periods; when water passes through the pond, some impurities in the water will settle at the bottom of the pond, which can improve the water quality; store a large amount of water during the rainy season or other peak water flow periods, reduce the flooding of rivers or streams, prevent floods, and 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 regulating reservoir occupies a large area. In order to make full use of geographical resources, it is usually combined with photovoltaic power generation. Photovoltaic power generation requires photovoltaic pipe piles to be driven into the soil layer at the bottom of the regulating reservoir. Photovoltaic pipe piles are the core infrastructure in the photovoltaic power generation system, mainly used to support photovoltaic components and ensure the stability and power generation efficiency of the system.

[0004] However, in order to prevent water leakage in the regulating reservoir, an anti-seepage membrane is usually laid on the pool wall and bottom for anti-seepage treatment, such as the common high-density polyethylene geomembrane. In this way, when driving the photovoltaic pipe pile, it is necessary to penetrate the anti-seepage membrane at the bottom of the regulating reservoir, and the penetration point of the anti-seepage membrane becomes the main leakage risk point in the regulating reservoir.

[0005] In order to solve the above-mentioned problems, the present invention proposes an active pressurizing anti-seepage device and a method of use for photovoltaic pipe piles penetrating an anti-seepage membrane.

[0021] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0022] Embodiment 1: Please combine Figure 1-Figure 7 The active pressurized anti-seepage device for the photovoltaic pipe pile to penetrate the anti-seepage membrane of this embodiment comprises a soil bin 1, an equipment bin 2 and an air bag 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 ring of the pressure-dividing bin 4 is fixedly connected to the soil bin 1, the soil bin 1 is penetrated by a channel 5 connected to the equipment bin 2, the channel 5 is equipped with an adjustment component 6 connected to the soil bin 1 and the equipment bin 2, an inflation control component 10 is fixedly connected to the top of the adjustment component 6, an air bag 11 is arranged in the air bag bin 3, the soil bin 1, the equipment bin 2, the air bag bin 3 and the pressure-dividing bin 4 are all hollow annular structures, and a hanging hook for hoisting is welded on the top of the soil bin 1; The adjustment component 6 includes a lifting mechanism 7 fixedly connected to the top inner wall of the soil bin 1 and the bottom inner wall of the equipment bin 2, and a support plate 9 for carrying the inflation control component 10, and a lifting and stabilizing mechanism 8 slidably connected to the lifting mechanism 7 is fixedly connected to the outer side of the support plate 9; The lifting mechanism 7 includes two groups of movable plates 71 moving in the vertical direction, a limiting plate 72 fixed between the two groups of movable plates 71, and a limiting channel 73 penetrating the limiting plate 72. The limiting channel 73 is slidably connected to the lifting and stabilizing mechanism 8. The limiting channel 73 is used to guide and limit the movement of the lifting and stabilizing mechanism 8. One of the movable plates 71 is threadedly sleeved with a screw 75 for driving the movable plate 71 to lift. 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 deflection rod 1 82 and a deflection rod 2 84. The other end of the deflection rod 1 82 is fixedly connected to a driven rod 1 83, and the other end of the deflection rod 2 84 is fixedly connected to a driven rod 2 85. The driven rod 1 83 and the driven rod 2 85 are both slidably connected to the limiting channel 73. The bottom of the cross bar 51 is fixedly connected to a first slot plate 52 for adjusting the state of the driven rod 1 83 and a second slot plate 54 for adjusting the state of the driven rod 2 85.

[0023] A motor fixedly connected to the inner wall of the bottom of the equipment bin 2 is fixedly connected to the bottom of the screw rod 75, a support frame fixedly connected to the equipment bin 2 is movably sleeved on the outer ring of the screw rod 75, an adjustment rod rotatably sleeved on the top of the soil bin 1 is fixedly connected to the top of the screw rod 75, and an operating groove with a regular polygonal structure is provided at one end of the adjustment rod extending out of the top of the soil bin 1. When the battery is exhausted, a handle consistent with the cross-section of the operating groove is inserted into the operating groove, and the handle is turned to manually drive the screw rod 75 to rotate, thereby manually driving the lifting mechanism 7 to perform lifting operations.

[0024] 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 wall of the top of the soil bin 1, and the bottom of the guide rod 74 is fixedly connected to the inner wall of the bottom of the equipment bin 2. A cover plate is hinged on one side of the opening of the channel 5. The motor is started to drive the screw 75 to rotate, so that the movable plate 71 moves in the vertical direction under the guidance of the guide rod 74, realizing the primary lifting operation of the lifting mechanism 7 on the inflation control assembly 10 on the support plate 9, and lifting the inflation control assembly 10 along the equipment bin 2 to the soil bin 1.

[0025] The first slot plate 52 includes an inclined section fixed to the bottom of the cross bar 51 and a holding section arranged at the bottom of the inclined section and fixed to the inner side wall of the bottom of the equipment bin 2. The first slot plate 52 is provided with an adjustment slot 53 distributed along the direction from the inclined section to the holding section. The second slot plate 54 has the same structure as the first slot plate 52. The cross bar 51 is fixed to the inner side wall of the top of the soil bin 1. When the inflation control assembly 10 is lifted upward with the lifting mechanism 7 and the movable plate 71 is lifted, the four sets of lifting and stabilizing mechanisms 8 arranged on the outer side of the support plate 9 form a triangular structure during the lifting process, so that the support plate 9 can rise smoothly without deflection. On the other hand, when the inflation control assembly 10 is lifted, it can extend the inflation control assembly 10 from the channel 5 at the top of the soil bin 1 to the top of the inflation control assembly 10, thereby realizing the secondary lifting of the inflation control assembly 10, and at the same time improving the connection strength and stability of the overall structure, 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. When lifting, as the movable plate 71 rises, the limiting plate 72 is first moved upward, and the driven rod 1 83 and the driven rod 2 85 on the limiting channel 73 on the limiting plate 72 also move upward accordingly, and then the adjustment slot 53 on the lifting and stabilizing mechanism 8 is used to adjust the distance between the driven rod 1 83 and the driven rod 2 85. During the rising stage, under the action of the limiting channel 73, a triangular structure is formed between the driven rod 1 83 and the driven rod 2 85 and the deflection rod 1 82 and the deflection rod 2 84, so that the position of the top support rod 81 does not deviate when it rises. On the one hand, the four groups of support rods 81 rise smoothly. On the other hand, the deflection rod 1 82 and the deflection rod 2 84 are pushed to deflect and drive the support rod 81 to move upward relative to the movable plate 71 when the movable plate 71 rises, so that the support plate 9 is determined to perform a second rise when the lifting mechanism 7 rises, thereby improving the lifting stroke and stability.

[0026] The top of the airbag 11 is connected to an air supply pipe 13 extending upward and extending from the outer wall of the soil bin 1. An air pressure sensor is installed on the air supply pipe 13. A valve and an air pipe joint for inflation are installed at one end of the air supply pipe 13 extending from the soil bin 1. The air pressure sensor is used to detect the air pressure of the airbag 11 during use. At the same time, it can also be replenished from the outside of the soil bin 1 using the air pipe joint to ensure the overall service life of the air pressure increasing device of the airbag 11; the soil bin 1 is provided with a humidity sensor 14 for detecting the humidity of the soil filled in the soil bin 1, so as to realize the air supply of the airbag 11 to the pressure reducing bin 4. The humidity sensor 14 adopts an embeddable soil humidity sensor. There are two humidity sensors 14, which are distributed in sequence along the vertical direction.

[0027] The top of the pressure-dividing bin 4 is provided with air holes connected to its inner cavity, and the top and inner circle of the pressure-dividing bin 4 are paved with geotextiles. The airflow used by the pressure-dividing bin 4 to inflate the soil is discharged upward into the soil along the air holes, and the geotextiles are used to protect the air holes to prevent the mud, sand and gravel in the soil from entering the pressure-dividing bin 4 along the air holes. At the same time, the geotextiles arranged in the inner circle of the pressure-dividing bin 4 are in conflict with the pipe piles to prevent the soil from overflowing downward from the gap between the inner circle of the pressure-dividing bin 4 and the outer circle of the pipe piles. The soil bin 1 includes a top plate and a bottom plate of an annular structure, an inner closing plate of an annular structure fixed between the inner circles of the top plate and the bottom plate, and an outer closing plate of an annular structure fixed between the outer circles of the top plate and the bottom plate. Reinforcing ribs are fixed between the top plate and the bottom plate and the inner closing plate and the outer closing plate. The reinforcing ribs can improve the overall strength of the soil bin 1 and the equipment bin 2, the air bag bin 3 and the pressure dividing bin 4 to prevent deformation and damage of the soil bin 1 and the equipment bin 2, the air bag bin 3 and the pressure dividing bin 4 during long-term use. The structures of the soil bin 1 and the equipment bin 2, the air bag bin 3 and the pressure dividing bin 4 are consistent. Geotextile and anti-seepage membrane are laid in sequence on the bottom of the air bag bin 3 from top to bottom, and geotextile is filled between the inner circle of the air bag bin 3 and the outer circle of the photovoltaic pipe pile; 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 deflection rod 82 .

[0028] Embodiment 2: The present embodiment is further improved on the basis of the embodiment 1 in that: the inflation control assembly 10 includes a control box fixedly connected to the support plate 9, the control box is provided with an inflator, a battery compartment, a controller and a wireless transceiver, the battery compartment is provided with a battery, the output end of the inflator is connected to an air pipe 1 connected to the pressure dividing chamber 4, the input end of the inflator is connected to an air pipe 2 connected to the airbag 11, and the inflator is used to transport the gas in the airbag 11 to the pressure dividing chamber 4; the control box is installed with a data interface and a switch, and the controller is connected with the motor, the humidity sensor 14, the battery, the inflator, the air pressure sensor and the wireless transceiver.

[0029] Embodiment 3: The method for using the active pressurizing anti-seepage device for photovoltaic pipe piles to penetrate the anti-seepage membrane comprises the following steps: Step S1: Design and assembly of active pressurized anti-seepage device: Determine the size of the active pressurized anti-seepage device according to the buried depth and diameter of the photovoltaic pipe pile, as well as the size design drawings and complete the production and assembly operations of the active pressurized anti-seepage device; Step S2: reserve space for installing the active pressurization anti-seepage device on the outside of the photovoltaic pipe pile, and hoist the active pressurization anti-seepage device to the outside of the photovoltaic pipe pile using a hoisting device to complete the installation operation of the active pressurization anti-seepage device; Step S3, filling the interior of the active pressurizing anti-seepage device with soil for anti-seepage, and using the active pressurizing anti-seepage device to perform pressurizing and anti-seepage operations on the photovoltaic pipe piles.

[0030] When active pressurization and anti-seepage are performed, dry clay soil is added to the soil bin 1 in the device and the air bag 11 is inflated using the air pipe joint on the air supply pipe 13 on the soil bin 1. When the pressure detected by the air pressure sensor reaches the set value, it indicates that the inflation of the air bag 11 is completed; Since the flow rate of water seepage satisfies the following formula; ; Where Q is the flow rate of water seepage per unit time ( ); k is the permeability coefficient of the soil ( ); A is the water-passing section ( ); is the total head difference ( ); L is the seepage path length ( ); The above formula shows that the principle of seepage is caused by the water head difference. When the pressure inside the viscous soil in the soil bin 1 is increased to a level greater than the water head difference, the seepage path can be changed, that is: P> h, where P is the pressure of the cohesive soil (Pa); is the total head difference ( ), changing the downward seepage path to upward seepage and discharging the seepage water upward can meet the project's need for anti-seepage at the pipe pile connection.

[0031] After the device is installed, water begins to seep from the connection between the pipe piles during rainfall or other circumstances. Since the clay in the soil bin 1 is close to the pipe piles, the water seepage will only start from the clay in the soil bin 1. The water seepage will increase the humidity of the clay. When the humidity exceeds the warning value, the upper humidity sensor 14 will transmit data to the controller, and the water will continue to seep downward in the clay. When the lower humidity sensor 14 also detects that the humidity exceeds the warning value and feeds back the data to the controller, the controller will start the inflator to start working, and the gas in the airbag 11 will be pumped out through the air pipe. The gas is filled into the pressure-dividing chamber 4 at the bottom of the soil chamber 1 and then into the clay soil from the air holes at the top of the pressure-dividing chamber 4. At this time, the pressure in the clay soil changes due to the filling of gas. Since the seepage of water is due to the pressure difference, the pressure in the clay soil is increased by pressurizing the bottom of the soil chamber 1, which changes the pressure difference between the soil and the water surface. When the pressure in the clay soil is greater than the pressure of water on the clay soil, the seepage path of water will change, and it will seep from bottom to top, that is, the water is discharged upward from the clay soil to prevent the water from seeping in along the gap at the connection of the pipe pile. When the rain stops or the water on the edge of the pile dries up, because the pressurized water of the clay soil is discharged upward, the lower humidity sensor 14 should first detect that the humidity of the clay soil is decreasing, and transmit the data to the controller when the humidity is lower than the normal value; when the water seeps upward to the upper humidity sensor 14, the upper humidity sensor 14 also detects that the humidity is lower than the normal value and feeds back to the controller, the controller will turn off the inflator, reduce the loss of gas in the air bag 11, and extend the use time; the gas in the air bag 11 can be observed at any time by the air pressure sensor outside the soil body bin 1, and the air pressure sensor shows how much gas is left in the air bag 11. When the air pressure sensor shows that the air pressure is lower than the warning value, the air bag 11 can be directly inflated from the air pipe joint. After use, it is only necessary to regularly inspect whether the gas in the air bag 11 is sufficient and replenish it at any time.

[0032] The design utilizes the soil bin and equipment bin, air bag bin and pressure distribution bin installed on the outside of the photovoltaic pipe pile, and adopts the method of supplying air to the soil upward to realize active pressurization and anti-seepage operation, effectively preventing water from penetrating downward along the gap between the outside of the photovoltaic pipe pile and the anti-seepage membrane, solving the leakage problem at the connection point where the photovoltaic pipe pile penetrates the anti-seepage membrane, enhancing the anti-seepage capacity of the regulating reservoir and other pools laid with the anti-seepage membrane, ensuring the normal operation of the regulating reservoir, avoiding groundwater pollution and foundation settlement of surrounding buildings caused by water leakage in the regulating reservoir, and effectively playing the role of the regulating reservoir in controlling non-point source pollution and urban torrents; a two-stage lifting method is used to lift the control air supply components completely stored inside the device upward to the top of the device, so that maintenance operators can replace them at the top of the device, increase the lifting stroke, solve the problem of increased overall weight of the device caused by insufficient lifting stroke, complex structure and more components of traditional lifting components, and improve the stability and running smoothness of the overall device, and realize manual operation for lifting and maintenance when the power is exhausted.

[0033] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
