Description

Technical Field

[0001] The present invention relates to the technical field of ecological restoration, and in particular to a rainwater collection device for ecological restoration of power transmission and transformation projects and a method for using the device. Background Art

[0002] After the completion of a power transmission and transformation project, relevant policies and regulations require the implementation of vegetation planting and ecological restoration projects. Ensuring a water supply is crucial for vegetation restoration. However, many of the tower bases in power transmission and transformation projects are located in remote areas with low rainfall, resulting in a lack of directly accessible water sources and high maintenance costs. Therefore, rainwater collection devices must be installed in the vegetation planting areas to collect rainwater for vegetation irrigation and ecological restoration. Existing rainwater collection devices only collect rainwater and do not provide flood irrigation for vegetation. Summary of the Invention

[0003] The technical problem to be solved by the present invention is how to collect part of the rainwater during rainfall and use the other part of the rainwater directly for flood irrigation.

[0004] The present invention solves the above technical problems through the following technical means:

[0005] A first aspect of the present invention provides a rainwater collection device for ecological restoration of power transmission and transformation projects, which includes at least one water collection unit, and the water collection unit includes at least one water collection pipe, the water collection pipe and the water collection mechanism are connected by a third threaded pipe, the water collection pipes are connected in parallel and connected to the diversion pipe, and the diversion pipe is connected to the water collection tank; the water collection pipe is provided with flooding ports on both sides of the third threaded pipe, and the third threaded pipe is provided with a flooding mechanism that can open the flooding port through rainwater.

[0006] Beneficial effects: The flooding mechanism of the present invention can block the flooding outlet. When it rains, the present invention collects rainwater through the water collecting mechanism, and collects the rainwater in the water collecting tank through the water collecting pipe and the diversion pipe for subsequent use; if there is too much rainwater in the water collecting pipe, the flooding mechanism will be activated to open the flooding outlet. At this time, part of the rainwater flows out through the flooding outlet and is directly used for irrigation. If there is heavy rain, the flooding outlet can reduce the pressure of collecting rainwater and reduce the effect of vegetation being washed away by heavy rain.

[0007] The present invention can adapt to different vegetation restoration areas by splicing different numbers of water collection units or water collection pipes. When there is no wind or rain, the rainwater collection device of the present invention can reduce the sun's temperature, prevent vegetation from being dehydrated and withered due to exposure to the sun, and increase the survival rate of vegetation.

This allows for the installation of different numbers of water collection pipes based on the repair area, thereby providing water collection units with varying repair areas, better accommodating vegetation coverage. The present invention also allows for the connection of water collection units to the left or right side of the water collection pipe, increasing the rainwater collection efficiency of the rainwater collection device and its ability to protect vegetation. If the water collection pipe does not require connection to a water collection unit, a second sealing cap seals one side of the water collection pipe, while both ends of the diversion pipe are sealed with sealing plugs to prevent rainwater loss.

[0016] Preferably, the water collecting mechanism includes a water collecting frame, which is connected to the water collecting pipe via a third threaded pipe. The water collecting frame is funnel-shaped, and a filter cover is provided on the top of the water collecting frame.

[0017] Preferably, the water collecting frame and the filter cover are made of a transparent material, and the transparent material is one of acrylic, polycarbonate and transparent glass fiber reinforced plastic.

[0018] Preferably, a card slot is provided on the outer side of the top of the water collecting frame, and a corresponding card buckle is provided on the bottom of the filter cover.

[0022] Beneficial effect: The guide ring of the present invention is used to introduce rainwater in the water collecting frame into the third threaded tube through the guide ring. The sealing gasket is provided at the bottom of the guide ring so that when the third threaded tube and the support ring are connected through a threaded connector, the guide ring and the third threaded tube squeeze the sealing gasket, thereby reducing water leakage in the connection gap.

[0023] Preferably, an oblique support bar is provided inside the water collecting tank, and a filter screen is provided on the top of the oblique support bar.

[0024] Beneficial effects: The present invention fixes the position of the filter screen by means of oblique support bars, and filters impurities in the water of the water collection tank through the filter screen.

[0025] Preferably, a support frame for supporting the water collecting pipe is provided below the water collecting pipe, and the support frame can be extended and retracted in the horizontal direction and the vertical direction.

[0026] Beneficial effects: The present invention provides an installation position for the spliced ​​water collecting pipe and water collecting mechanism through a support frame, elevates the position of the water collecting pipe and water collecting mechanism relative to the ground, and can place the water collecting pipe on the ground or use a support frame for support according to actual needs to ensure vegetation at different heights at the bottom and ensure ventilation of the vegetation.

When the water collecting tank is full of rainwater, the water level of the rainwater rises in the water collecting pipe, and then the flooding port is opened through the flooding mechanism, so that the rainwater flows out from the flooding port; or the electromagnetic valve is closed, and the rainwater flows into the water collecting pipe through the water collecting mechanism, so that the rainwater level in the water collecting pipe rises, and then the flooding port is opened through the flooding mechanism, so that the rainwater flows out from the flooding port.

[0030] Beneficial effects: The rainwater collection device for ecological restoration of power transmission and transformation projects of the present invention can determine whether to open the electromagnetic valve when it rains based on the amount of rain collected in the water collection tank or the water collection tower; if the electromagnetic valve is opened to collect rainwater, when the rainwater in the water collection tank is full, the water level of the rainwater rises in the water collection pipe, and then the flooding port is opened by the flooding mechanism, so that the rainwater flows out from the flooding port, thereby realizing the collection of part of the rainwater and the use of part of the rainwater for irrigation; if the electromagnetic valve is closed, the rainwater flows into the water collection pipe and the diversion pipe through the water collection mechanism, and since the electromagnetic valve is closed, the rainwater cannot flow into the water collection tank, thereby causing the water level in the water collection pipe to rise, and then the flooding port is opened by the flooding mechanism, so that the rainwater flows out from the flooding port, thereby realizing the direct use of rainwater for irrigation, and being used to reduce the scouring of heavy rain.

[0031] When there is heavy rain or short-term heavy rainfall, the water level in the water collection pipe rises, and the flooding outlet is opened through the flooding mechanism, so that the rainwater is diverted and flooded through the flooding mechanism, reducing the erosion of vegetation by rainwater.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0044] Unless otherwise specified, the test materials and reagents used in the following examples can be obtained from commercial sources.

[0045] If no specific techniques or conditions are specified in the examples, they can be carried out according to the techniques or conditions described in the literature in the field or according to the product instructions.

[0046] Example 1

[0047] according to Figure 1 As shown, this embodiment provides a rainwater collection device for ecological restoration of power transmission and transformation projects, which includes a water collection unit, wherein the water collection unit includes 5 water collection pipes 1, the 5 water collection pipes 1 are connected in parallel, the 5 water collection pipes 1 are connected to multiple water collection mechanisms 2, the 5 water collection pipes 1 are connected to the diversion pipe 4, and the diversion pipe 4 is connected to the water collection tank 5.

[0048] This embodiment uses one water collection unit as an example. Five water collection pipes 1 are provided for one water collection unit, which is the standard configuration of the present invention. The number of water collection pipes 1 in one water collection unit can also be configured in different standard configurations depending on the length of the diversion pipe 4. The standard configuration of the present invention is to achieve the highest rainwater collection efficiency and the greatest wind and rain shielding effect for vegetation in one water collection unit. This embodiment can also be configured with 1-5 water collection pipes 1 to suit the actual vegetation area, so as to meet the actual vegetation area's usage effect.

[0049] according to Figure 1-4As shown, second threaded pipes 103 are provided on both sides of the five water collecting pipes 1, and the second threaded pipes 103 are linearly symmetrically and evenly distributed on both sides of the water collecting pipe 1. The five water collecting pipes 1 are connected in parallel, and the second threaded pipes 103 between the five water collecting pipes 1 are connected through a two-way threaded joint 6. The specifications and dimensions of the two-way threaded joint 6 are compatible with the specifications and dimensions of the water collecting pipe 1 and the second threaded pipe 103. The second threaded pipe 103 of the water collecting pipe 1 arranged on the outside is sealed by a second sealing cover 104 to prevent rainwater from being lost.

[0050] A first threaded tube 101 is provided at both ends of the five water collecting pipes 1, and a joint 404 is provided on one side of the diversion pipe 4. The specifications and dimensions of the joint 404 are compatible with the specifications and dimensions of the first threaded tube 101 of the water collecting pipe 1. The number of the joints 404 is five, and one diversion pipe 4 is connected to five water collecting pipes 1 at most. The first threaded tube 101 at one end of the five water collecting pipes 1 is connected to the joint 404 of the diversion pipe 4. The joint 404 is a threaded flexible joint for connecting the first threaded tube 101 of the water collecting pipe 1, thereby ensuring that rainwater flows into the interior of the diversion pipe 4 through the water collecting pipe 1, and then enters the interior of the water collecting box 5 through the diversion pipe 4; the five water collecting pipes 1 are provided with a first sealing cover 102, and the other end of the five water collecting pipes 1 is sealed by the first sealing cover 102 to prevent rainwater from being lost.

[0051] A first thread 401 is provided on the outer side of both ends of the diversion pipe 4. The diversion pipes 4 are connected by a two-way threaded joint 6 to expand the splicing area and improve the efficiency of rainwater collection. In this embodiment, since there is only one water collection unit, only one diversion pipe 4 is required. Therefore, a second thread 403 is provided inside the two ends of the diversion pipe 4. The diversion pipe 4 is provided with a sealing plug 402, which is used to seal both ends of the diversion pipe 4 to prevent rainwater from being lost.

[0052] The water collecting mechanism 2 includes a water collecting frame 201, which is a rectangular funnel-shaped frame. A filter cover 203 is provided on the top of the water collecting frame 201, and a card slot 202 is provided on the outer side of the top of the water collecting frame 201. A buckle 204 is provided on the bottom of the filter cover 203. The filter cover 203 is engaged with the card slot 202 of the water collecting frame 201 through the buckle 204, and the filter cover 203 is fixed to the top of the water collecting frame 201, so that the filter holes of the filter cover 203 block leaves and other debris flying in the wind and rain, reduce the probability of blockage by debris, and ensure that rainwater can enter the interior of the water collecting frame 201, and then enter the guide pipe 4 and the water collecting tank 5 in turn.

[0053] according to Figure 1As shown, a third threaded tube 105 is provided on the top of the water collecting pipe 1, and the third threaded tube 105 is linearly and evenly distributed on the top of the water collecting pipe 1. In this embodiment, 11 third threaded tubes 105 are provided on the top of one water collecting pipe 1. The number of the third threaded tubes 105 is set according to actual conditions, for example, according to the size of the water collecting frame 201.

[0054] A support ring 205 is provided at the bottom of the water collecting frame 201, and the support ring 205 is connected to the third threaded tube 105 by a threaded connector 3. In this embodiment, one water collecting pipe 1 can fix 11 water collecting frames 201, thereby improving the rainwater collection efficiency. Five water collecting pipes 1 fix 55 water collecting frames 201, and the water collecting mechanisms 2 are evenly distributed on the tops of the five water collecting pipes 1 in a rectangular array. There is no gap between the 55 water collecting frames 201, and they are close to each other on the left and right to reduce gaps. They can collect rainwater to the greatest extent and shield vegetation from rainwater, thereby ensuring the rainwater collection efficiency and facilitating connection.

[0055] according to Figure 8 As shown, the bottom of the water collecting frame 201 is sleeved with a guide ring 206, and the guide ring 206 is conical. A sealing gasket 207 is provided at the bottom of the guide ring 206. When the water collecting frame 201 and the third threaded tube 105 are connected and fixed by the support ring 205 and the threaded connector 3, the conical guide ring 206 promotes rainwater to flow from the water collecting frame 201 into the third threaded tube 105, and the sealing gasket 207 connects the gap to reduce water leakage; the specifications and dimensions of the third threaded tube 105 match those of the support ring 205, the guide ring 206 and the threaded connector 3.

[0056] according to Figure 9 As shown, the water collecting pipe 1 is provided with flooding ports 1010 on both sides of the third threaded tube 105, and a flooding mechanism 10 is provided inside the third threaded tube 105. The flooding mechanism 10 includes a float 1009, which is placed in the water collecting pipe 1. The top of the float 1009 is connected to the limit frame 1003. A support shaft 1004 is provided inside the limit frame 1003. Both ends of the support shaft 1004 are fixed on the inner wall of the third threaded tube 105. The limit frame 1003 is connected to the spring 1002, and the spring 1002 is connected to the bracket 1001. The bracket 1001 is a cross bracket, which is fixed on the inner wall of the third threaded tube 105.

[0057] The two sides of the floating block 1009 are connected to the connecting rod 1006, one end of the connecting rod 1006 is connected to the sealing plate 1005, and the sealing plate 1005 can just block the flooding port 1010. The connecting rod 1006 is provided with a limiting groove 1007, and a fixed shaft 1008 is provided in the limiting groove 1007. Both ends of the fixed shaft 1008 are fixed on the inner wall of the water collecting pipe 1.

[0058] When the present invention is in use, when it rains, rainwater is collected by the water collection mechanism 2, and the rainwater flows into the water collection pipe 1, the guide pipe 4 and the water collection box 5 through the third threaded tube 105. The water level of the rainwater in the water collection pipe 1 rises, and at the same time, the floating block 1009 rises, and the limit frame 1003 also rises. The connecting rod 1006 moves to both sides of the floating block 1009, so that the fixed axis 1008 moves from the top of the sliding groove 1007 to the bottom of the sliding groove 1007, and prompts the blocking plate 1005 to move away from the flooding port 1010. At this time, the rainwater can overflow through the flooding port 1010, thereby achieving the purpose of flooding.

[0059] The water collection frame 201 and filter cover 203 are made of a transparent material, such as acrylic, polycarbonate, or transparent fiberglass reinforced plastic. The water collection frame 201 and filter cover 203 collect rainwater and filter debris. They also shield vegetation from wind and rain, ensuring that rain does not cause devastating scouring of the vegetation. They also lower temperatures, preventing dehydration and wilting of the vegetation due to sun exposure, thereby increasing its survival rate. Sunlight can penetrate the filter cover and water collection frame, allowing the vegetation to fully photosynthesize, improving the restoration process and efficiency, and increasing the utilization rate of the rainwater collection device of the present invention.

[0060] The three materials have different effects, ensuring that different materials are used in different environments. The details are as follows:

[0061] 1. Acrylic material has good optical properties and a high light transmittance of about 92%, which allows more light to pass through, reducing the obstruction of vegetation light. The light transmission is relatively uniform, which can reduce the risk of poor vegetation growth due to uneven lighting. It can maintain stable performance for a long time in outdoor environments, is not easy to turn yellow or brittle, and can provide relatively stable lighting conditions for vegetation for a long time, reducing the adverse effects of material aging affecting light transmittance on vegetation growth.

[0062] 2. Polycarbonate offers high light transmittance and impact resistance, with a transmittance typically ranging from 88-92%, ensuring sufficient light reaches the vegetation. Furthermore, its excellent impact resistance makes it less susceptible to damage from external impacts, preventing damage to the vegetation's growth environment or physical harm from broken material. It also exhibits excellent UV stability, effectively blocking some UV rays and protecting vegetation from excessive UV damage while allowing visible light, which is beneficial to photosynthesis, to pass through, promoting normal vegetation growth.

[0063] 3. Transparent glass fiber reinforced plastic has moderate light transmittance and soft light, and the light transmittance is generally around 70-85%. Although the light transmittance is slightly lower than that of acrylic and polycarbonate materials, it has a strong ability to scatter light, which can make the light shine more softly and evenly on the vegetation, reduce direct strong light and light spot phenomenon, which is beneficial to vegetation photosynthesis and can reduce the possibility of uneven vegetation growth due to uneven lighting. It has good corrosion resistance and durability, can resist the erosion of various chemicals, has a long service life in harsh outdoor environments, can ensure long-term and stable provision of a suitable growth environment for vegetation, reduce the interference to vegetation growth caused by frequent replacement due to corrosion and damage of the material, is light in weight, easy to install and move, and is not easy to cause mechanical damage to surrounding vegetation during installation. The lighter weight also reduces the requirements for the supporting structure.

[0064] according to Figure 1 、 Figure 3 and Figure 10 As shown, the guide pipe 4 is connected to the water collecting box 5 through a hose 503, and an electromagnetic valve is provided in the hose 503. By controlling the electromagnetic valve to close, the rainwater level in the water collecting pipe 1 rises when it rains, so that the blocking plate 1005 is away from the position of the flooding port 1010. At this time, the rainwater can overflow through the flooding port 1010 to achieve the purpose of flooding.

[0065] The top of the water collection tank 5 is hingedly provided with a sealed lid 502. A threaded connection pipe 501 is provided at the bottom of one end of the water collection tank 5. Two diagonal supports 505 are provided inside the water collection tank 5. A filter screen 504 is placed on top of the two diagonal supports 505. The filter screen 504 filters fine impurities in the rainwater to prevent clogging of the threaded connection pipe 501. The threaded connection pipe 501 is connected to a water storage pump 8 via a hose. The water storage pump 8 is further connected to a water collection tower 7 via a hose. The water collection tower 7 collects rainwater through the water storage pump 8, with the purpose of collecting the rainwater for use.

[0066] A photovoltaic panel 508 is provided on the top of the sealed box cover 502 , a rod frame 507 and a control box 509 are provided on the bottom of the sealed box cover 502 , and a liquid level sensor 506 is provided on the outside of the rod frame 507 .

[0067] The control box 509 is internally provided with a photovoltaic panel charging controller, a wireless networking module, a battery pack module and a microcontroller module. This solution is adopted when rainwater collection requires control and feedback, such as the opening and closing of the electromagnetic valve. The signal is received through the wireless networking module, and the closure of the electromagnetic valve is controlled by the microcontroller module to achieve the drip irrigation effect. The photovoltaic panel 508 receives sunlight for photovoltaic power generation, and the electrical energy is stored in the battery through the photovoltaic panel 508 charging controller. When the water level inside the water collection tank 5 is high, the feedback signal from the liquid level sensor 506 indicates that the internal water level is already high. The signal is fed back to the operator's control background through the wireless networking module. The operator remotely starts the water storage pump 8 and can know the water collection amount at the first time. This embodiment provides an intelligent control solution, which further increases the convenience and control capability of multi-area use of multi-point paving.

[0068] according to Figure 11 As shown, a support frame 9 for supporting the water collecting pipes 1 is provided below the five water collecting pipes 1. The support frame 9 includes two fixed rods 91 and multiple telescopic rods 92. The two ends of the telescopic rods 92 are respectively connected to the two fixed rods 91, which serve as support parts of the support frame 9; the two ends of the two fixed rods 91 are connected to the four telescopic rods 92, which serve as support legs of the support frame 9.

[0069] The telescopic rod 92 includes a first telescopic rod 921 and a second telescopic rod 922. The first telescopic rod 921 is sleeved on the second telescopic rod 922. The first telescopic rod 921 and the second telescopic rod 922 are both provided with adjustment holes (not shown in the figure), and a telescopic bolt (not shown in the figure) is provided on the second telescopic rod 922. The telescopic rod 92 is fixed by passing the telescopic bolt through the adjustment holes of the first telescopic rod 921 and the second telescopic rod 922.

[0070] In this embodiment, the area of ​​the support part of the support frame 9 is adjusted in the horizontal direction through the telescopic rod 92, so that its size can adapt to the size of the water collection unit; the telescopic rod 92 adjusts the length of the support leg of the support frame 9 in the vertical direction, so that its height can adapt to vegetation of different heights, ensuring the ventilation needs between the vegetation, adapting to most rainwater collection operating environments, and increasing adaptability.

[0071] Example 2

[0072] This embodiment provides a method for using a rainwater collection device for ecological restoration of power transmission and transformation projects. Specifically, the water collection unit of Example 1 is used for the tower base site. After the tower base is constructed, the disturbed soil is backfilled, and grass seeds are re-sown to restore vegetation at the biological level. Subsequently, the water collection unit of Example 1 is installed and evenly arranged above the backfill area.

[0073] In the initial stage (0-7) of sowing, in case of light rain, the soil in the covered area is not lost, and the electromagnetic valve is controlled to allow the flooding mechanism to flood the vegetation; in case of moderate rain, the soil in the covered area is not lost, and the electromagnetic valve is controlled to allow the flooding mechanism to flood the vegetation; in case of heavy rain, the soil in the covered area is not lost, the electromagnetic valve is in the open state, and the water collection unit is diverted and flooded through the flooding mechanism to keep the internal soil moist; in case of heavy rain, the soil in the covered area is not lost, and a small amount of soil in the edge area is washed away, which does not affect the development of grass seeds inside, and the interior is flooded normally.

[0074] During the grass seed germination period (7-14 days), the seedling roots are shallow (<2cm). When encountering short-term heavy rainfall, the soil inside the covered area does not lose, and only a small amount of soil is lost at the edge.

[0075] Therefore, installing the water collection unit in the vegetation restoration area after the tower base construction can withstand heavy rain, has good soil conservation effect, and has excellent moisture retention and light effects, which is beneficial to the biological level vegetation restoration by re-sowing grass seeds in the power transmission and transformation project.

[0076] Comparative Example 1

[0077] In this comparative example, after the tower base construction, the disturbed soil was backfilled and grass seeds were re-sown to restore the vegetation at the biological level. The grass seeds were shallow-rooted plants to prevent affecting the underground cables. No water collection unit was installed afterwards.

[0078] In the initial stage (0-7) of sowing, the soil does not erode under light rain and remains moist; under moderate rain, some unrooted grass seeds in the soil are washed away, with a wash rate of 20%; under heavy rain, the grass seed wash rate reaches 50%, and mixed mud and sand accumulate in low-lying areas; under torrential rain, most of the grass seeds are washed away, with a wash rate of 60%.

[0079] During the grass seed germination period (7-14 days), the seedlings have shallow roots (<2cm). When encountering short-term heavy rainfall, the seedlings and soil are lost in large areas.

[0080] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
