Description

Technical Field

[0001] This utility model relates to the field of ecological slope protection, and in particular to an ecological slope protection maintenance system. Background Technology

[0002] Ecological slope protection is a common type of slope protection structure in water conservancy projects, combining vegetation and engineering measures, and it has been particularly well applied in large-scale water conservancy projects. Currently, ecological slope protection typically employs ecological gabions combined with planting herbaceous plants or fixed-vegetation ecological slope protection. During the rainy season, rainfall can meet the growth needs of the plants on the slope. However, when faced with prolonged drought or inadequate maintenance, the vegetation on the slope will not receive sufficient water support for extended periods, making it highly susceptible to death. The death of the vegetation leads to soil erosion of the topsoil, exposing the fixed gabion structure, and ultimately failing to achieve the combined benefits of slope protection and aesthetics. Summary of the Invention

[0003] In view of this, this utility model proposes an ecological slope protection maintenance system that can use collected rainwater or water from river channels to spray and maintain the slope, preventing the vegetation on the slope from dying.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: The ecological slope protection maintenance system described in this utility model includes a solar photovoltaic unit that converts solar energy into electrical energy, as well as a spraying unit, a rainwater collection unit, a water storage tank, a water replenishment unit, and a control unit buried in the slope. The water replenishment unit includes a water pump installed in the reservoir, a floating water intake cylinder installed in the water, and a pipe buried in the slope. The upper end of the pipe has two paths: one path is connected to the inlet of the water pump, and the other path is connected to the reservoir and equipped with a first electric valve. The lower end of the pipe is divided into two paths: one path is connected to a channel or river and equipped with a one-way valve, and the other path is connected to the floating water intake cylinder. The rainwater collection unit includes a water collection ditch located at the top of the slope protection, and the water collection ditch is connected to the water storage tank through a water collection pipe extending downward at an incline. The spraying unit includes a spraying pipeline buried in the slope protection, a water spray head installed on the spraying pipeline, and a water pump installed in the water storage tank. The water pump is connected to the spraying pipeline. The control unit includes a controller, a liquid level sensor installed in the water storage tank, and a humidity sensor installed in the soil of the slope protection vegetation. The output terminals of the liquid level sensor and the humidity sensor are both connected to the input terminal of the controller. The output terminal of the controller is connected to the input terminal of the water pump, the water spray pump, and the first electric valve.

[0005] The beneficial effects are: This utility model pre-buries spray pipes and water storage tanks on the ecological slope protection. The collected rainwater can be stored in the water storage tank, or river water can be pumped out for storage. When encountering drought, the spray pumps and spray pipes can be used to spray water to irrigate the vegetation on the slope protection, preventing the vegetation from drying out due to lack of water.

[0006] Preferably, a rain grate is laid above the water collection ditch, and the upper end of the water collection pipe extends into the water collection ditch; drainage ditches connected to the water collection ditch are spaced along the water flow direction on the slope. The beneficial effects are: this utility model lays a rain grate above the water collection ditch, ensuring rainwater enters the ditch while protecting pedestrians; a filter screen can be installed below the rain grate to prevent leaves, branches, and other impurities from entering.

[0007] More preferably, a second electric valve is provided at the upper end of the water collection pipe, and the second electric valve is connected to the controller. The second electric valve can be closed when the water storage tank is full.

[0008] Preferably, the water storage tank has a sunken structure with its bottom surface inclined downwards; the water pump is a submersible pump, and the inlet of the water pump is connected to the water storage tank through an inlet pipe, with a first filter screen installed at the inlet end of the inlet pipe. The first filter screen protects the water pump; the water storage tank is designed as a sunken structure, with its top sloped to match the slope, effectively ensuring the aesthetics of the slope protection; the bottom surface of the water storage tank is inclined to facilitate sludge removal and cleaning.

[0009] Preferably, the solar photovoltaic system includes a first photovoltaic panel mounted on a road pole and a second photovoltaic panel inclined along the slope direction, with the second photovoltaic panel hinged to the top of the reservoir. The design of the first and second photovoltaic panels in this invention effectively ensures power supply; the second photovoltaic panel can convert solar energy and also serve as the roof of the reservoir, facilitating maintenance.

[0010] Preferably, a rainwater trough is provided below the second photovoltaic panel. The rainwater trough is located inside and connected to the water storage tank, and the top opening of the rainwater trough is inclined and connected to the second photovoltaic panel. Rainwater or snowmelt on the second photovoltaic panel can enter the water storage tank through the rainwater trough to collect water.

[0011] Preferably, the control unit also includes a rain gauge mounted on a pole.

[0012] Compared with the prior art, the advantages of this utility model are: This invention pre-buries spray pipes and a water storage tank on the ecological slope protection.

These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0021] It should be noted that in the description of this utility model, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0022] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Combination Figure 1-7It is understood that this utility model proposes an ecological slope protection maintenance system, including a solar photovoltaic unit that converts solar energy into electrical energy, a spraying unit buried in the slope, a rainwater collection unit, a water storage tank 1 buried in the slope, a water replenishment unit, and a control unit. The water storage tank 1 is a sunken tank, which can be made of stainless steel or concrete. The water storage tank 1 is waterproofed to prevent leakage. The bottom wall of the water storage tank 1 adopts a sloping structure with a certain slope, which is conducive to cleaning particulate sediment (such as mud). It can be washed by rainwater in heavy rain. The water replenishment unit includes a water pump 2 (preferably a submersible pump, with the lowest water level in the reservoir 1 being the lower limit level required for the operation of the water pump 2) installed in the reservoir 1, a floating water intake cylinder 3 installed in the water (which floats up and down with changes in the water level to ensure water intake), and a pipe 4 buried in the slope. The upper end of the pipe 4 has two branches: one connected to the inlet of the water pump 2, and the other connected to the reservoir 1 and equipped with a first electric valve 5 (this branch is for venting); the lower end of the pipe 4 splits into two branches. One branch extends into the channel or river and is equipped with a one-way valve 6 (this branch, combined with the drain branch, can drain the water in the reservoir 1), while the other branch is connected to the floating water intake cylinder 3. When the water in the reservoir 1 is insufficient and the slope protection needs to be sprayed for maintenance, the water pump 2 is used to pump water into the reservoir 1, and then the spraying unit is used for spraying maintenance to meet the needs of slope protection maintenance. During cleaning, the first electric valve 5 is opened, allowing the water in the reservoir 1 to enter the channel or river by gravity, and the one-way valve 6 can prevent reverse flow. The rainwater harvesting unit includes a collection ditch 7 located at the top of the slope (near the road on the top of the embankment and adjacent to the slope). The collection ditch 7 is connected to the reservoir 1 via a downwardly extending collection pipe 20. The inlet of the collection pipe 20 extends into the collection ditch 7 and is equipped with a second electric valve 8. The inlet of the collection pipe 20 is located at the top of the collection ditch to allow the upper layer of clean water to flow into the reservoir as much as possible. Drainage ditches 21 connected to the collection ditch 7 are installed at intervals along the direction of water flow on the slope. The drainage ditches 21 are located on the slope and can discharge the water in the collection ditch 7 into the river channel when the rainfall is heavy. A rain grate 19 is laid above the collection ditch 7 to protect pedestrians while ensuring that rainwater enters the collection ditch 7. A filter screen can be installed below the rain grate to prevent impurities such as leaves and branches from entering and to ensure smooth water flow.

[0024] Combination Figure 3 and Figure 5It is understood that the spraying unit includes a spraying pipeline 10 buried in the slope protection, spray heads 11 installed on the spraying pipeline 10, and a water pump 9 installed in the water storage tank 1. The water pump 9 is connected to the spraying pipeline 10. In actual construction, the spraying pipeline 10 can be buried in the slope protection (such as in a crisscross pattern), and spray pipes can be vertically installed on the spraying pipeline 10 (the spray pipes are located above the slope protection). Each spray pipe is equipped with a spray head 11, preferably a rotary nozzle, so that it can rotate and spray under water pressure to ensure the spraying area.

[0025] Combination Figure 1 , Figure 7 It is understood that the control unit includes a controller, a level sensor and a temperature sensor installed in the water storage tank 1, a humidity sensor 12 installed in the soil of the slope vegetation, and a rainfall monitor 13 (installed on the pole 14) for monitoring rainfall. The output terminals of the temperature sensor, rainfall monitor 13, level sensor, and humidity sensor 12 are all connected to the input terminal of the controller. The output terminal of the controller is connected to the input terminals of the water pump 2, the sprinkler pump 9, the first electric valve 5, and the second electric valve 8. When the level sensor is used to monitor the level information of the water storage tank 1, water can be pumped out (or rainwater can be stored) when the level is insufficient, and water storage stops when the level reaches the upper limit. The minimum level of the water storage tank needs to meet the starting requirements of the water pump. Temperature sensors are used to monitor the water temperature in the reservoir. In the hot and dry summer, if the water temperature in the reservoir exceeds 37 degrees Celsius, watering should be avoided during the high-temperature period to prevent the water temperature from being too high and affecting the vegetation. Humidity sensor 12 is used to monitor soil moisture. When the soil moisture is lower than a certain value, water pump 9 can be started to spray water to meet the maintenance needs of slope protection plants. Rainfall monitor 13 is used to monitor rainfall. When the rainfall is heavy, the second electric valve 8 and the first electric valve 5 can be opened to use the rainwater in the middle of the period to clean the water storage tank 1 and prevent sludge from accumulating in the water storage tank 1. When the water is stored, the first electric valve 5 is in the closed state.

[0026] During actual installation, a monitor 18 (which can be a camera) can be installed on the pole 14 to monitor the situation at the inlet of the water collection pipe 20 and transmit the monitored information to the controller for easy viewing.

[0027] In actual installation, the controller can be a general-purpose processor, a dedicated processor, a conventional processor, a digital signal processor (DSP), multiple microprocessors, one or more microprocessors associated with a DSP core, a controller, a microcontroller, a PLC, etc. Furthermore, the controller can also be equipped with a wireless communication module to connect with a remote terminal, receive control commands from the remote terminal, and thus achieve automatic water storage and sprinkling.

[0028] Combination Figure 1 and Figure 3 It is understood that the solar photovoltaic system provides power to the various electrical components of this utility model, which includes a first photovoltaic panel 15 installed on the road pole 14, a second photovoltaic panel 16 installed at an inclination along the slope direction, and an energy storage device, which provides power to the various electrical components through the energy storage device; The second photovoltaic panel 16 is hinged to the top of the water storage tank 1. The combination of the first photovoltaic panel 15 and the second photovoltaic panel 16 effectively ensures power supply. The second photovoltaic panel 16 can also serve as the top plate of the water storage tank 1, which facilitates maintenance. A rainwater trough 17 is installed below the second photovoltaic panel 16. The rainwater trough 17 is located inside and connected to the water storage tank 1. The top opening of the rainwater trough 17 is inclined and connected to the second photovoltaic panel 16, so that the rainwater on the second photovoltaic panel 16 enters the water storage tank 1 through the rainwater trough 17. This achieves water collection on the one hand, and avoids the rainwater on the photovoltaic panel washing away the vegetation on the lower side when the rainfall is heavy, so as to prevent damage to the vegetation and soil erosion.

[0029] During actual installation, a filter screen is installed on the lower surface of the rain grate to reduce impurities; a third filter screen is installed at the inlet of the water collection pipe 20 to further prevent blades and large particles from entering the water storage tank 1; the inlet of the water pump 9 is connected to the water storage tank 1 through the inlet pipe, and a first filter screen is installed at the inlet end of the inlet pipe to protect the water pump 9.

[0030] In actual installation, the floating water intake cylinder 3 of this utility model adopts a cylinder with a float ring, and the upper surface of the cylinder is covered with a fourth filter screen to prevent floating objects in the water from entering the water storage tank 1.

[0031] This utility model pre-buries a spray pipe 10 and a water storage tank 1 on an ecological slope. The collected rainwater can be stored in the water storage tank 1, or river water can be pumped out and stored using a water pump 2. When encountering drought, the water pump 9 and the spray pipe 10 can be used to spray water to irrigate the vegetation on the slope, preventing the vegetation from drying out due to lack of water.

[0032] The working process and principle of this utility model are as follows: When starting for the first time, ensure that the water level in the reservoir 1 meets the starting requirements of the water pump 2 (rainwater can be collected by the collection ditch 7, or water can be manually added to the reservoir 1 through the collection pipe 20). Secondly, water is stored in the water storage tank 1. When there is sufficient rainfall in the area where this utility model is located, rainwater storage is given priority. Specifically, the rainwater monitor monitors the rainfall and transmits it to the controller. During the middle of the rainy season, the second electric valve 8 is opened, allowing the clearer rainwater in the upper layer of the collection ditch 7 to enter the water storage tank 1 through the collection pipe 20. The liquid level sensor monitors the water level of the water storage tank 1 in real time. When the maximum water level is reached, the second electric valve 8 is closed to stop water storage. When there is insufficient rainfall, pump 2 is started to draw clean water from the river. The level sensor monitors the water level of reservoir 1 in real time until the maximum water level is reached, at which point pump 2 is turned off to stop water storage. When the soil moisture sensor 12 indicates that the soil moisture level is below the set limit and the water temperature in the reservoir is below 37 degrees Celsius, the controller activates the water pump 9. The water pump 9 draws water from the reservoir 1 and sprays it out through the spray head 11, achieving rotary spraying for maintenance. The water pump 9 is then turned off when the soil moisture reaches the set upper limit, thus completing the slope protection maintenance. In hot summer weather, the temperature is high at midday, causing the reservoir water temperature to rise. Spraying can be avoided during this time, choosing to spray in the evening or morning.

[0033] During operation, rainwater and river water often contain small particles that accumulate in the reservoir 1, forming sludge. Therefore, to ensure the normal operation of the system, the reservoir 1 needs to be cleaned regularly. Cleaning is preferably carried out during periods of heavy rainfall. First, the first electric valve 5 is opened to drain the water from the reservoir 1. Then, the second electric valve 8 is opened, allowing rainwater to enter the reservoir 1 through the collection pipe 20 and flush the bottom wall of the reservoir 1. The sludge flows into the river through the pipe 4. After cleaning for a certain period, the first electric valve 5 is closed, stopping the discharge from the reservoir 1. Rainwater accumulates in the reservoir 1. Once the water storage is complete, the second electric valve 8 is closed, completing the cleaning and water storage process.

[0034] Finally, it should be emphasized that the above description is merely a preferred embodiment of this utility model and is not intended to limit this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
