Description

Technical Field

[0001] The present application belongs to the field of ecological governance technology, and in particular, relates to a zero-carbon self-repairing system and topological structure for medium-to-large-sized river sediment. Background Art

[0002] Sediment transport is an important hydrological phenomenon in rivers, which has a significant impact on the evolution of rivers (see riverbed evolution). The rock and soil particles in the river are transported by the water flow or eroded and deposited on the riverbed and beach. The weathered rock and soil are the main source of river sediment. When heavy rain falls on the surface of the basin, in the process of runoff and confluence, the rock and soil of the slopes and gullies are eroded and transported to the river by the water flow to form river sediment. In the process of transporting sediment, the river will also scour the riverbed or riverbank, further increasing the amount of sediment. When the river enters the downstream plain area, the gradient decreases, the flow rate slows down, and part of the sediment carried by the water flow will be deposited on the riverbed or beach. Because the flow rate of the river drops sharply near the estuary, the sediment will be deposited in the sea near the estuary. According to the characteristics of sediment transport, it can be divided into bedload and suspended load (see river sediment movement). In the suspended sediment, some fine-grained sediment is carried away by the water flow, does not settle in the riverbed, and does not participate in the exchange of riverbed sediment. It is called flushing sediment or non-bed-forming sediment. The remaining coarser particles participate in the exchange and flushing and silting changes of riverbed sediment, and are called bed sand or bed-forming sediment.

[0003] The distribution of sediment content along the water depth is usually the smallest at the water surface and the largest at the river bottom. The content of coarse sediment in the suspended sediment is very large near the river bottom. It decreases sharply from the river bottom to the top. Finer particles, such as silt and clay, are more evenly distributed along the water depth. The sediment content is basically distributed in a certain exponential curve along the water depth, and the index value is related to the size of the sediment particles and the water flow conditions. Due to the influence of various side currents in the water, the maximum sediment content may not be near the river bottom, but at a certain position above the river bottom. The distribution of sediment content in the cross section of the river varies with the water flow conditions on the section. If the distribution of water flow on the section is relatively uniform, the lateral distribution of sediment content is relatively uniform. If the water flow conditions are more complicated, the lateral distribution of sediment content is often very uneven. The distribution of sediment content along the length of the river generally decreases from upstream to downstream, and also depends on the degree of influence of factors such as the sediment production characteristics of the basin, the characteristics of the river channel, and the influx of tributaries. The middle reaches of the Yellow River flow through the Loess Plateau, with tributaries with high sand content flowing into it along the way, so the sand content actually increases along the way. The riverbed in the lower reaches becomes open, and a large amount of silt is deposited, so the sand content tends to decrease.

[0004] The sediment problem in medium and large rivers will have the following impacts: Affecting aquatic life and water quality. The transport and deposition of sediment in the reservoir will change the landform, hydrology, water quality, suspended sediment concentration and bed sand quality in the water body. These changes directly affect the living environment of aquatic life, amphibians, waterfowl, etc., and affect water pollution. Pollutants in the reservoir are enriched at the bottom of the reservoir with sediment accumulation. Although this is conducive to the self-purification of the water body and the improvement of the water quality of the river channel below the dam, it may also become a potential secondary pollution source; affecting the flow and navigation of the river. Sediment accumulation will cause the riverbed to silt up, affecting the flow and navigation of the river, and may even cause floods; threatening the production and life of residents along the coast. River sedimentation will cause the water level upstream of the dam to rise, and the groundwater level near the coast to rise, which may lead to soil swamping and salinization, seriously affecting industrial and agricultural production and life; affecting the operation of the reservoir. Sediment accumulation will lose the effective storage capacity of the reservoir, change the riverbed landform, affect navigation, increase flooding losses; and threaten the safety of the water body. River siltation may cause harmful substances such as heavy metals and organic pollutants to be deposited in the riverbed mud. These substances are not easily degraded by light and microorganisms, nor are they easily oxidized. They may penetrate into groundwater bodies, seriously threatening water safety and affecting water quality and the water ecological environment.

[0005] River siltation has always been a problem that needs to be solved urgently. The measures currently taken are all from the perspective of ecology and management. Therefore, it is a new method that needs to be explored to coordinate the entire river in an intelligent manner, practice the zero-carbon concept, and combine new energy, intelligence and ecological protection.

[0021] The medium-to-large-scale river sediment zero-carbon self-repairing system and topological structure provided in the embodiments of the present application have the following beneficial effects:

[0022] 1. This application provides a new method for treating sediment in medium and large rivers. Traditional river restoration methods are generally used for small black and smelly water bodies. The following are commonly used technical methods for river restoration: First, physical restoration: dredging, river bank solidification, and water system connectivity to improve the fluidity of the water body and enhance the self-purification ability of the water body; second, chemical restoration: flocculation sedimentation, oxidation-reduction, and nutrient control to inhibit the growth of algae in the water body, thereby improving water quality; third, biological restoration: ecological floating islands, biofilm technology, and biological manipulation, by adjusting the population structure of aquatic organisms to improve water quality and restore ecological balance; fourth, ecological restoration: wetland restoration, vegetation restoration, etc.; fifth, comprehensive restoration technology: combining multiple restoration technologies such as physical, chemical, biological, and ecological to achieve a comprehensive restoration effect.

For medium and large rivers, these are impossible to adopt. The energy consumption is too high, and the reconstruction of the ecosystem will cause serious ecological damage. This patent utilizes the height difference of the river channel and the characteristics of sediment transport, adopts bottom pipes to suck out sediment, and provides an energy base on the bridge without taking up additional space. This is the main innovation of this application.

[0023] 2. This application installs a photovoltaic array on at least one side of the river bridge, calculates the maximum photovoltaic output power generated by the photovoltaic array according to the length of the bridge, calculates the total amount of sediment that needs to be processed by the mud brick integrated machine, and selects the model of the mud brick integrated machine based on the maximum photovoltaic output power and the total amount of sediment, so that the amount of photovoltaic energy generated by the photovoltaic array matches the energy consumption of the mud brick integrated machine, forming a medium-to-large-scale river sediment zero-carbon self-repair.

[0025] 4. This application can provide a water source for the photovoltaic panel cleaning robot and the curing agent spraying device through a clever structural design.

Figure 1 As shown, this embodiment provides a medium-to-large river channel sediment zero-carbon self-repairing system 100, which is suitable for medium-to-large river channels, and the bridge length is at least 1000 meters. The medium-to-large river channel sediment zero-carbon self-repairing system 100 in this embodiment includes: a mud brick integrated machine 120 (mud press and brick making machine integrated machine) is provided next to the river channel, and a photovoltaic array 110 is installed on at least one side of the river channel bridge. Preferably, photovoltaic arrays 110 are installed on both sides of the river channel bridge, and the photovoltaic arrays 110 convert direct current into alternating current through an inverter to power the mud brick integrated machine 120. For example, a photovoltaic array 110 is added to a medium-to-large river channel bridge. After the photovoltaic array 110 converts direct current into alternating current through an inverter, it is mainly used for the operation of the mud brick integrated machine 120, and the remaining electricity is stored by an energy storage device to be used for the power consumption of auxiliary equipment in the medium-to-large river channel sediment zero-carbon self-repair.

[0047] In this embodiment, photovoltaic panels 111 are set up on both sides of the bridge fence 210 to form a photovoltaic array 110, and the output power of each photovoltaic array 110 is calculated, and the maximum photovoltaic energy, that is, the maximum photovoltaic output power, is determined by the output power of each photovoltaic array 110. Among them, the photovoltaic energy generated by the photovoltaic array 110 is allocated to the mud brick integrated machine 120 according to a preset ratio value, and the remaining photovoltaic energy is stored in the energy storage device.

The empirical parameter is to arrange photovoltaic panels in 1-2 rows, and the arrangement angle does not exceed 30°. is the inverter conversion efficiency, is the number of hours of electricity generated per day. In this embodiment, the photovoltaic panels on both sides of the river bridge are connected in series, and each photovoltaic string on each side corresponds to an inverter.

It is the number of hours per day, usually calculated on a daily basis, i.e. 24 hours.

[0054] This embodiment also provides a topological structure of a medium-to-large-sized river sediment zero-carbon self-repairing system, including the medium-to-large-sized river sediment zero-carbon self-repairing system as described above, energy storage equipment, a photovoltaic panel cleaning robot, a curing agent spraying device 150 and a data device; wherein, a topological structure is formed between the photovoltaic array 110, the mud brick integrated machine 120, the energy storage equipment, the photovoltaic panel cleaning robot, the curing agent spraying device 150 and the data device (not shown in the figure) to form a medium-to-large-sized river sediment zero-carbon self-repairing system.

[0055] Specifically, in this embodiment, the topology structure includes: the connection topology of the photovoltaic array 110 and the energy storage device. The connection relationship between the photovoltaic array 110 and the energy storage device is that the photovoltaic panels 111 are connected in series and then enter the combiner box, and the combiner box enters the inverter and then enters the energy storage device. Figure 2 The diagram shows the connection between the photovoltaic panel 111 and the energy storage device in the medium-to-large-scale river sediment zero-carbon self-repairing system 100 according to one embodiment of the present application. Figure 2 As shown, the photovoltaic panels 111 of the photovoltaic array 110 are connected in series and then connected to a photovoltaic combiner box, and the photovoltaic combiner box is connected to the energy storage device via the inverter.

[0056] This application sets up a topological structure between the power side and the load side of the river, and can layout all river data through logical operations, thereby realizing the logic of the zero-carbon self-repair automation system for sediment in medium and large rivers, and realizing bridge-to-bridge interconnection, sand-to-brick transportation interconnection, and energy-to-electricity interconnection in medium and large rivers.

[0060] In the topological structure, the network logic relationship is: the photovoltaic array 110 and the energy storage device are gathered in the data device for storage and logical operations, mainly for power supply side data. The mud brick integrated machine 120, the photovoltaic panel cleaning robot, and the curing agent spraying device 150 are gathered in the data device, mainly for load side data.

The water flowing into the water storage tank 143 is used by the photovoltaic panel cleaning robot to clean the photovoltaic panel 111 and dissolve the curing agent of the curing agent spraying device 150.

[0064] Figure 4 The diagram shows the connection between the water collection equipment, the photovoltaic array 110 and the bridge 220 in the medium-to-large river sediment zero-carbon self-repairing system 100 according to one embodiment of the present application. Figure 4 As shown, in this embodiment, the bridge 220 supports the bridge deck 200, and a bridge fence 210 is arranged on the bridge deck 200. The photovoltaic panel 111 is obliquely installed on the bridge fence 210, and the water collecting net 141 is suspended in the shade of the photovoltaic panel 111. The bottom of the water collecting net 141 and along the length direction of the photovoltaic array 110 is a water collecting trough 142. The water collected on the water collecting net 141 will flow into the water collecting trough 142 at the bottom, and then the water in the water collecting trough 142 will flow into the water storage tank 143 on the shore.

[0065] Illustratively, in the present application, the water collected by the water collection device is dew. After the dew is collected by hanging a dew collection net 141 in the shade of the photovoltaic panel 111 or by using facilities such as an unpowered dew collector, the dew flows into the dew storage soft water tank on the shore through a dew collection trough 142. The water is used as cleaning water for the photovoltaic panel 111 and dissolving water for river sediment solidification agent.

[0066] This application can provide a water source for the photovoltaic panel cleaning robot and the curing agent spraying device through a clever structural design. The water source is mainly soft water, which will not increase the hardness, and provide more possibilities for the use of water. The use of technologies such as dew collectors and photovoltaic panel cleaning robots is common in fields such as desert photovoltaic sand control. This application just takes advantage of the bridge-side layout of photovoltaic panels. At the same time, the water collection system in this application is designed after comprehensive consideration of issues such as high water vapor above the river and the difficulty of photovoltaic operation and maintenance on highway and railway bridges.

[0067] In one embodiment of the present application, it further includes: setting a pipeline 130 at the bottom of the river channel, Figure 5 The schematic diagram of the installation position of the pipeline 130 in the medium-to-large river sediment zero-carbon self-repairing system 100 according to one embodiment of the present application is shown. Figure 5 As shown, the pipe 130 is provided with an open groove, wherein the opening is oriented obliquely downward. Figure 6 As shown, a filter screen 131 is arranged above the groove, and the river sediment swirls to the river bottom through the groove on the pipe 130 to form a sediment suction hopper, and the bottom of the sediment suction hopper is connected to the suction port of the mud brick integrated machine 120, as shown in FIG. Figure 7 As shown, the present application can effectively improve the suction efficiency of the mud brick machine by setting up the pipeline 130 structure due to the silt migration caused by the height difference. In order to prevent silt accumulation and damage to the pipeline 130 at the rear side of the pipeline 130, the slope of the rear of the pipeline is inclined, so that the bottom pipeline can be pumped without clogging.

[0068] In one embodiment of the present application, Figure 5 As shown, a sloped chute is provided at the rear of the pipeline 130 to prevent sediment accumulation at the rear side of the pipeline 130 and prevent the pipeline 130 from being damaged.

[0069] In one embodiment of the present application, the diameter of the pipe 130 is 20 cm to 40 cm; the pore size of the filter 131 is 2 cm to 3 cm.

[0070] Figure 8 The schematic diagram of the application of the spraying station 160 and the curing agent spraying device 150 in the medium-to-large-scale river sediment zero-carbon self-repairing system 100 of one embodiment of the present application is shown. Figure 8As shown, in one embodiment of the present application, it also includes: a spraying table 160 for placing the semi-cured bricks generated by the mud brick machine 120; wherein, there are multiple curing agent spraying devices 150, which are respectively aimed at the sharp corners of the semi-cured bricks.

[0071] After the mud brick machine 120 produces bricks, the semi-cured bricks are placed in the spraying table 160, and the curing agent spraying device 150 is used to spray the sharp corners of the semi-cured bricks so that the semi-cured bricks are ready for transportation. By setting the curing agent spraying device 150, the semi-cured bricks produced by the mud brick machine 120 can be ready for transportation.

[0072] The present application sets a curing agent spraying device to make the semi-cured bricks generated by the mud brick integrated machine ready for transportation. Since the use of the semi-cured bricks in the later stage is not clear, the semi-cured bricks can be quickly made into bricks. Since the semi-cured bricks are easy to scatter mainly at the sharp corners during transportation, a small amount of curing agent is used to spray the main parts at fixed points to speed up the brick making and transportation efficiency.

[0073] The application of the medium-to-large river sediment zero-carbon self-repairing system 100 of this embodiment is described below with reference to a specific application example.

[0074] This embodiment selects one of the highway bridges as an implementation case of this patent. The bridge is about 1300m long. Taking the monocrystalline silicon photovoltaic panels purchased on the market as an example, the specifications are 2256*1133*35mm, the standard output power is 540W, the rated power of the inverter is 225kW, the maximum output is 247.5kW, the inverter conversion efficiency is 98.5%, and the maximum photovoltaic panel layout is about 2000 / 2.256=886 photovoltaic panels, which are arranged in 2 rows (one for backup and one for use), with no gaps between the panels.

[0075] By formula W Storage = [ （ k * L bridge / L one piece Light Volt plate long Spend ） * W one plate lose out achievement Rate ] * 2 * η inverse Change Device change Change effect Rate * h Calculate the maximum photovoltaic output power:

[0076] W 储 =[(1*1300 / 2.256)*540]*2*98.5%*4.1=2513 kW, the actual power provided to the mud brick machine 120 is 50%, that is, 1256 kW is actually used.

[0077] By formula Q sand = P i * [ A i * h sand * w river * l river + K i B i * w river * （ h river − h sand ） * v water * t ] Calculate the total amount of mud and sand that the mud brick machine 120 needs to process.

[0078] The looseness of the bottom mud is relatively low, with Ai taking the value of 0.05%, h sand: W river: 1200 meters, l river: 2000 meters, Bi: 27%, v water: 2.0m / s.

[0079] h sand: the thickness of river sediment measured by remote sensing or acoustics (m), the average of 20-40 groups of measured data, and the measured total depth of the river h sand is 3 meters; h river: the total depth of the river measured by remote sensing or acoustics (m), the average of 20-40 groups of measured data, 0.5 meters; l river: empirical value 2000m; Ai: 0.05% (empirical value); Ki: 0.02% (empirical value); Ai:Ki=5:2; Bi: the proportion of sand in water, no unit, 27%; v water: water flow velocity (m / s), 5.4km / h; t: generally calculated per day, 24 hours; Pi: empirical value 2%.

[0080] Q 沙 :=

[0081] 2%*(0.05%*0.5m*1200m*2000m+*0.02%*27%*1200m*(3m-0.5m)*5400m / h*24h)

[0082] =(600+20995.2)*2%=431.9m 3 / d.

[0083] Selection method of mud brick machine 120:

[0084] 431.9 / 24=17.996m3 / d, which is approximately equal to 20m3 / d. The power is generally 50KW (including all electrical equipment such as pumps). 50KW*24h=1200 kWh, which matches the actual power of 1256 kWh provided to the mud brick machine 120, that is, the power-generating equipment matches the power-consuming equipment, which can achieve zero-carbon self-repair of sediment in medium and large rivers.

[0085] Fig. 9 The topological structure diagram of the medium-to-large-scale river sediment zero-carbon self-repairing system 100 is shown in one embodiment of the present application. Fig. 9 As shown, the S0 node is an energy storage device, the S1 node is a photovoltaic array 110, the S2 node is a mud brick integrated machine 120, the S3 node is a photovoltaic panel 111 robot, and the S4 node is a curing agent spraying device.

[0086] The connection relationship between S0 and S1 is that the photovoltaic panels 111 are connected in series and then enter the combiner box, and then enter the energy storage system after entering the inverter in the combiner box.

[0087] The connection relationship between S1 and S2 is that power is directly supplied to S2 through the inverter.

[0088] The connection between S0 and S3 and S4 is that the energy storage system provides stable power supply to S3 and S4.

[0089] Network logic relationship: S0 and S1 converge to the S total data storage and logic operation system, which is mainly the power supply side data. S2, S3, and S4 converge to the S total data storage and logic operation system, which is mainly the load side data. All river data can be laid out through computer logic operations, and through the collection of node information, river water and soil erosion data, river mud volume collection data, river sediment resource data, river energy data, carbon emission reduction data, etc. can be finally realized. Realize the intelligent operation of the entire river and realize the self-repair function of the river.

[0090] Through the topological structure of the Yangtze River Bridge, the river sand utilization enterprises are united, and the electricity generated by the clean energy photovoltaics deployed on the bridge is combined to achieve net zero carbon emissions. On the power supply side and the load side, the topological system is used as a logical guide to provide basic data for waste-free rivers. The river is no longer divided into affiliations, and a set of topological systems is used to transport river sediment to designated application enterprises.

[0091] In summary, this application provides a new method for treating sediment in medium and large rivers. Traditional river restoration methods are generally carried out for small black and smelly water bodies. The following are commonly used technical methods for river restoration: First, physical restoration: dredging, river bank solidification, and water system connectivity to improve the fluidity of the water body and enhance the self-purification ability of the water body; second, chemical restoration: flocculation sedimentation, oxidation-reduction, and nutrient control to inhibit the growth of algae in the water body, thereby improving water quality; third, biological restoration: ecological floating islands, biofilm technology, and biological manipulation, by adjusting the population structure of aquatic organisms to improve water quality and restore ecological balance; fourth, ecological restoration: wetland restoration, vegetation restoration, etc.; fifth, comprehensive restoration technology: combining multiple restoration technologies such as physical, chemical, biological, and ecological to achieve a comprehensive restoration effect. The above methods are very mature technologies for setting up cofferdams and dams for river restoration in small rivers. For silt deposition, mechanical dredging is generally the main method. For medium and large rivers, these are impossible to adopt. The energy consumption is too high, and the reconstruction of the ecosystem leads to serious ecological damage. This patent utilizes the height difference of the river channel and the characteristics of sediment transport, adopts bottom pipes to suck out sediment, and provides an energy base on the bridge without taking up extra space. This is the main innovation of this application. This application installs a photovoltaic array on at least one side of the river bridge, calculates the maximum photovoltaic output power generated by the photovoltaic array according to the length of the bridge, calculates the total amount of sediment that needs to be processed by the mud brick integrated machine, and selects the model of the mud brick integrated machine based on the maximum photovoltaic output power and the total amount of sediment, so that the amount of photovoltaic energy generated by the photovoltaic array matches the energy consumption of the mud brick integrated machine, forming a zero-carbon self-repair of sediment in medium and large rivers. With the existing bridge as the basis for photovoltaic installation, a distributed photovoltaic system is laid throughout the river. The photovoltaic system absorption problem is solved by powering the mud brick integrated machine as the main absorption source, and green electricity is used to manage river sediment. The law of sediment transport in the entire river can realize the integration of the self-repair ecosystem of the entire river. This application sets the topological structure between the power supply side and the load side of the river, and can layout all the river data through logical operations, so as to realize the logic of the medium and large river sediment zero-carbon self-repair automation system, and realize the medium and large river bridge-bridge interconnection, sand-brick transportation interconnection, and energy-electricity interconnection. This application sets a pipeline structure, and the sediment migration caused by the height difference can effectively improve the suction efficiency of the mud brick integrated machine. In order to prevent sediment accumulation and pipeline damage on the rear side of the pipeline, the slope chute behind the pipeline makes it possible to pump sand from the bottom pipeline without clogging. This application can provide a water source for the photovoltaic panel cleaning robot and the curing agent spraying device through clever structural design, and the water source is mainly soft water, which will not increase the hardness, and provide more possibilities for the use of water. In the fields of desert photovoltaic sand control, the use of technologies such as dew collectors and photovoltaic panel cleaning robots is common. This patent just uses the bridge side layout of photovoltaic panels. At the same time, the water vapor above the river and the difficulty of photovoltaic operation and maintenance on highway and railway bridges are comprehensively considered to design the water collection system in this application.The present application sets a curing agent spraying device to make the semi-cured bricks produced by the mud brick integrated machine ready for transportation. Since the use of the semi-cured bricks in the later stage is not clear, the semi-cured bricks can be quickly made into bricks. Since the semi-cured bricks are easy to scatter mainly at the sharp corners during transportation, a small amount of curing agent is used to spray the main parts at fixed points to speed up the brick making and transportation efficiency. Therefore, the present application effectively overcomes various shortcomings in the prior art and has a high industrial utilization value.

[0092] The above embodiments are merely illustrative of the principles and effects of the present application and are not intended to limit the present application. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present application. Therefore, all equivalent modifications or changes made by a person of ordinary skill in the art without departing from the spirit and technical ideas disclosed in the present application shall still be covered by the claims of the present application.
