Description
Technical Field
[0001] This utility model relates to the field of slope engineering technology, and in particular to a sprinkler irrigation system for slope greening. Background Technology
[0002] Mine slopes, especially steep slopes, refer to mine slopes with significant elevation and steep gradients, such as greater than 1:4. These slopes are typically formed by mining activities, geological structures, and surface water bodies, and pose a potential risk of geological disasters such as rockfalls and landslides. To address these issues, vegetation is often planted on mine slopes. To ensure the growth of these plants, slope irrigation equipment is used to irrigate them, guaranteeing their survival and development.
[0003] In existing technologies, vegetation on mine slopes is usually irrigated by manually dragging water pipes along pre-laid roads and accessible areas. This method has a limited irrigation range, creates dead zones, and cannot irrigate vertical or sloping sections or special corners of the slope. It also cannot adequately irrigate areas with high water demand, and it consumes a lot of manpower and resources, increasing irrigation costs.
[0004] Existing technologies also employ some irrigation equipment for watering, such as the ecological slope protection structure for steep mine slopes disclosed in Chinese Patent No. CN219547830U, which can supply water to sprinklers to irrigate slope protection plants through a water pump. Although this saves manpower, the above-mentioned structure also has problems such as limited irrigation range, dead corners, and inability to irrigate vertical tilted parts and special corners on the slope, as well as insufficient irrigation for areas with large water requirements, thus affecting plant growth. Summary of the Invention
[0005] The purpose of this utility model is to solve the above problems and provide a sprinkler irrigation system for slope greening. It can fully irrigate the dead corners of slopes, especially steep slopes in mines, and make reasonable use of water resources to fully irrigate the plants on the mine slopes, which is conducive to plant growth and stabilizes the slope.

[0020] 2. The sprinkler irrigation system for slope greening of this utility model can use tap water or surface water (such as river water) to irrigate the plants on the slope according to the actual situation, which is more selective, convenient to adapt to local conditions, and saves irrigation water resource costs; the sprinklers set in special locations can irrigate the vertical tilting parts of the slope, the planted trees, the parts with large water demand, and the corners and other special parts as needed, which is conducive to the growth of plants in the corresponding areas and effectively stabilizes the slope.

[0027] like Figure 1 The diagram shown is a structural schematic of a sprinkler irrigation system for slope greening according to this utility model. Figure 4 The diagram shown illustrates the application of this utility model's sprinkler irrigation system to a slope using river water for irrigation. Figure 1 , Figure 4As can be seen, the sprinkler irrigation system of this utility model includes: a water storage tank 4 installed at the toe of the slope and used to connect and store tap water or surface water; a slope top water tank 6 installed at the top of the slope and used to store water pumped in from the water storage tank; a water delivery pipe 8 for delivering water from the slope top water tank; a regulating valve 7 installed on the water delivery pipe for regulating the flow rate of the water it outputs; multiple transverse water pipes 9 connected to the water delivery pipe and spaced apart from the top of the slope to the toe of the slope; multiple longitudinal water pipes 10 spaced apart and extending longitudinally along the slope and perpendicularly connected to each transverse water pipe; multiple first nozzles 11 spaced apart on each longitudinal water pipe; and multiple second nozzles 18 installed at special locations 13 on the slope and connected to the transverse water pipes and / or the longitudinal water pipes.
[0028] The water in the reservoir can come from municipal water supply or surface water; if it is near a river, river water can be used (see [reference] 17). Figure 4 Furthermore, it also includes a water supply assembly for conveying tap water or surface water to the reservoir, which can employ, for example... Figure 1 The structure shown includes: an inlet pipe 1 connected to tap water or surface water; and a water filter 24 installed between the inlet pipe and the reservoir to filter impurities in the water. It also includes: a shut-off valve 21 installed on the inlet pipe near the water source to regulate the water flow; an vent valve 22 installed on the inlet pipe and located on one side of the shut-off valve to release gas; and a pair of pressure gauges 23 and 25 installed on the inlet pipe and located on the side of the vent valve away from the shut-off valve. The water filter is installed on the portion of the inlet pipe between the pressure gauges and is connected to the inlet pipe for pumping surface water into the reservoir.
[0029] In addition to the water filter installed between the inlet pipe and the water storage tank, this utility model can also install another water filter (not shown in the figure) at the inlet of the water transfer pipe 5 used to connect the water tank on the slope top of the water storage tank to filter impurities such as fine sand in the water. The water filter can be a 40-mesh disc water filter or other water filters in the prior art.
[0030] When a reservoir located at the foot of a slope pumps water to a tank at the top of the slope, due to the long distance and limited pumping distance, it may sometimes be necessary to add one or more additional slope tanks along the elevation between the two. Furthermore, since the slope may be a single-sided slope or a double-sided slope (e.g.,...),... Figure 4 As shown in the figure, slope water tanks can be installed on the left and right slopes on both sides of the slope crest, for example, see [reference]. Figure 4A right-slope water tank 14 is added to the right side of the slope at the top of the slope, and two slope water tanks 16 and 15 are added to the left side of the slope at the top of the slope. Correspondingly, a water storage tank is set at the foot of each side slope, and each water storage tank supplies water to the slope top water tank through a water supply assembly. When slope water tanks are set on the slope, water pumps need to be added between the water storage tank and the slope water tank, and between the slope water tank and the slope top water tank. In addition, one or more slope top water tanks can be used. When multiple slope top water tanks are used, the water supply pipelines can be interconnected and output from the same water supply pipe, or each slope top water tank can output from a separate water supply pipe. This embodiment only illustrates the example of the slope top water tank outputting from a single water supply pipe.
[0031] The water stored in the water tank at the top of the slope is transported via a water pipe to a transverse water pipe located at the top of the slope, running laterally along the slope. This water pipe can be made of, for example... Figure 3 The structure shown includes: a first water supply pipe 81 connected to the outlet of the hilltop water tank, with a regulating valve 7 installed on the first water supply pipe for adjusting the flow rate; a ball valve 82 installed on the first water supply pipe, located on the portion of the first water supply pipe not yet connected to the regulating valve; both the regulating valve and the ball valve can regulate the water flow rate from the hilltop water tank, providing double protection; furthermore, tightening the ball valve allows for continued water supply to the hilltop water tank via a storage tank; a second water supply pipe 84 connected to the first water supply pipe via an elbow; and a third water supply pipe 86 connecting the second water supply pipe and multiple horizontal water pipes. Additional water supply pipes can be added as needed. The regulating valve 7, ball valve 82, second water supply pipe 84, and portions of the first and third water supply pipes 81 and 86 can be housed within a valve box 83, with the upper part of the valve box exposed above ground. The box cover can be opened for easy inspection of the components. The bottom of the valve box can be fixed underground with concrete mortar.
[0032] This utility model arranges interconnected transverse and longitudinal water pipes at certain intervals along the slope, and sets several first nozzles 11 at intervals on the longitudinal water pipes. In addition, multiple second nozzles 18 are set at special locations 13 on the slope (see...). Figure 4 Special locations refer to vertically sloping areas on the slope (i.e., areas where the first sprinkler cannot reach or where the irrigation effect is poor), areas planted with trees, areas with high water requirements, uneven areas, and corners. The second sprinkler can be connected to horizontal and / or vertical water pipes through pipelines to ensure that plants in special locations can be effectively irrigated.
[0033] In addition, multiple transverse water pipe shut-off valves 12 are installed on the transverse water pipes at the top of the slope. These valves are located on both sides of the nodes where the transverse water pipes intersect with each longitudinal water pipe. The water flow can be adjusted for sprinklers at different locations along the transverse slope using these transverse water pipe shut-off valves.
[0034] To automatically control the water spraying of each sprinkler head, this invention also includes a controller 21, which can be a PLC controller. A solenoid valve 19 is installed at each sprinkler head, and a rainfall detection element 21 for detecting rainwater is installed at the water storage tank or the water pump. The solenoid valves, rainfall detection elements, and each water pump are all connected to the PLC controller to operate under its control. For example, when the rainfall detected by the rainfall detection element exceeds a preset threshold, the PLC controller stops the water pump pumping water to the water storage tank; when the rainfall detected by the rainfall detection element is below the preset threshold, the PLC controller starts the water pump pumping water to the water storage tank. When all or part of the vegetation on the slope needs to be irrigated by sprinklers, the PLC controller controls the solenoid valve at the corresponding location to activate the pipeline at the corresponding sprinkler head, allowing water to flow into the sprinkler head for irrigation. When the PLC controller controls the sprinkler heads, it can be controlled via physical switches, such as one switch per sprinkler head. When specific sprinkler heads on a particular area of the slope need to spray water, turning on the corresponding switch will automatically activate the sprinkler. Control can also be achieved wirelessly via Bluetooth through a monitoring terminal (such as a computer or mobile phone), or through pre-stored programs within the PLC controller. Furthermore, the spraying time of individual sprinklers can be controlled. The circuitry for controlling solenoid valves and other electrical components via the PLC controller is readily available to those skilled in the art and will not be described in detail here.
[0035] The water pump can be an oil-immersed pump or a deep well pump. When pumping water from the reservoir to the hilltop or slope-side water tank, one pump or multiple pumps can be used simultaneously. The PLC controller can be a Mitsubishi PLC controller, and the nozzles can be zinc alloy controllable 360° rotating nozzles. The diameters of all water delivery pipes can be the same or different. All the above components are existing technologies, and their structures will not be described in detail here.
[0036] Below, we will take the application of sprinkler irrigation systems as an example. Figure 4 The following is a description of the work process, using a mine slope as an example where river water is used for irrigation.
[0037] Two oil-immersed pumps are used to draw water from the river surface through a pre-filter (i.e., a water filter located between the reservoir and the river water) to the bottom pools (i.e., reservoirs) on both sides of the slope.
[0038] The river water pumped into the reservoir settles in the reservoir and is then filtered by a post-filter (i.e., a water filter located between the reservoir and the hilltop or hillside water tank) before being supplied to the hillside water tank by four 15kW stainless steel deep well pumps.
[0039] Water pumped into the slope water tank is supplied to the slope top water tank via two 135QJ12-250-37-15kW stainless steel deep well pumps.
[0040] Water from the hilltop water tank controls 96 solenoid valves via a PLC control box (including the aforementioned PLC controller), circulating water to each sprinkler head in two shifts throughout the day for irrigation. Each deep well pump has a flow rate of 20-30 cubic meters per hour, independently supplying 20-40 360° rotating sprinklers with a working flow rate of 0.8-1.6 cubic meters per hour. In rainy weather, the pumps stop operating via a rainfall detection element.
[0041] In application, an oil-immersed pump with a power of QY65-24-100-7.5kW can be used to draw water from the surface river into the quarry bottom reservoir. This pump has a flow rate of 65 cubic meters per hour and a head of 25 meters, which can meet production needs. A 135QJ20-180-24-15kW stainless steel deep well pump is used to supply water from the reservoir to the slope-top water tanks. This pump has a head of 180 meters and a flow rate of 20-30 cubic meters per hour, which can also meet production needs. A 135QJ12-250-37-15kW stainless steel deep well pump is used to supply water to four slope-top water tanks. Each tank has a storage capacity of 6 cubic meters, a pump head of 250 meters, and a flow rate of 12-22 cubic meters per hour, which can also meet production needs. In addition, the water stored in each tank can also meet the needs of forest fire fighting. The control system uses four Mitsubishi PLC control boxes, each capable of controlling 24 circuits, for a total of 96 solenoid valves. It operates in a timed cycle, divided into two periods (morning and afternoon). Within each cycle, each circuit of a single water pump simultaneously supplies water to 20-40 rotatable sprinkler heads. The solenoid valves are 2-inch outdoor underwater waterproof solenoid valves, and the sprinkler heads are 360° rotatable zinc alloy sprinkler heads with a working pressure of 2-4 kg, a flow rate of 0.84-1.62 cubic meters, and a spray diameter of 10-20 meters per hour. The following pipes can be used for each water supply pipe: the main pipe for drawing water from the river should use PE100, 1.6MP water pipe; the main pipe for the vertical section from the high-lift stainless steel deep well pump to the slope should use PE75, 1.6MP water pipe, and the main pipe for the horizontal section should use PE50, 1.6MP water pipe; the connection with the sprinkler head should use PE32, 1.6MP water pipe; the main pipe for water supply to the water tank at the top of the slope should use PE63, 1.6MP water pipe, gradually changing from PE50 to PE32, PE25, etc. Of course, water pipes of other diameters and materials can also be selected according to the actual situation.
[0042] In summary, this utility model's sprinkler irrigation system for slope greening can utilize tap water or surface water to irrigate plants on slopes according to actual conditions, offering greater flexibility and allowing for adaptation to local conditions while saving on irrigation water resource costs. Sprinklers at specific locations can connect to horizontal or vertical water pipes, ensuring sufficient irrigation for vertically sloping sections, planted trees, areas with high water requirements, and corners. Each sprinkler can automatically irrigate as needed, avoiding the problem of identical water volume for areas with lower and higher water requirements, as seen in existing technologies. Excessive water volume leads to overwatering in areas with lower water requirements, while insufficient water volume results in inadequate irrigation in areas with higher water requirements. This promotes plant growth and effectively stabilizes the slope. Water filters are installed before and after the water storage tank to prevent sediment from entering the water pipes and pumps, effectively preventing pump damage and water blockage, ensuring smooth irrigation of slope plants.
[0043] Although the present invention has been described in detail above, it is not limited thereto. Those skilled in the art can make modifications based on the principles of the present invention. Therefore, all modifications made in accordance with the principles of the present invention should be understood as falling within the protection scope of the present invention.
