Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of slope repair, and mainly relates to an ecological slope protection full-automatic irrigation system and method. BACKGROUND

[0002] Freezing soil problems are inevitable in ecological slope protection engineering construction, and the freezing and thawing of slope soil can cause local peeling of the cement-soil surface layer and other problems, thereby affecting the quality of ecological slope protection engineering. In view of the above-mentioned frozen soil slope protection problems, although there are now many different methods to solve the above-mentioned problems.

[0003] For example, a seasonal frozen soil area self-regulating temperature return energy consumption slope body supporting structure and construction method disclosed in CN104314088A protects the right item "The structure includes a lattice beam, an anchor rod, a spring and a heat preservation structure. Its characteristics are that the anchor rod is punched into the slope body, and the anchor rod is anchored in the stable soil layer by pressure injection of anchor slurry. The heat preservation structure and the geogrid are sequentially laid from the slope surface outward, and the sand mortar surface is sprayed. The lattice beam is applied on the slope surface. The anchor rod passes through the intersection part of the lattice beam. The anchor rod is sequentially sleeved with a pad and a spring. The anchor rod is anchored on the lattice beam by the anchor. A vertical drainage channel is provided at a certain distance along the slope surface. A water interception ditch is provided at the top of the slope. A drainage channel is provided at the foot of the slope. The structure has the functions of self-regulating temperature preservation, heat insulation, expansion reduction, shock absorption and self-return supporting, can timely comb water drainage, and effectively solves the slope instability caused by frost heaving and thawing settlement." However, the structure only pays attention to drainage and ignores the watering needs of plant growth. Since the slope operation is carried out by manual watering, it will consume manpower and waste water resources. Therefore, an automatic irrigation structure is needed.

[0004] A seasonal frozen soil engineering overwintering protection coiled material and construction method disclosed in CN113846527A protects the right item "Through the cooperation of the heat preservation coiled material and the moisture absorption coiled material, a high-efficiency overwintering protection coiled material is formed. Starting from the mechanism of seasonal frozen soil, the moisture absorption coiled material absorbs excess water in the near-surface soil layer, avoids the freezing and downward development of water in the near-surface soil layer, and stably releases a small amount of heat during the water absorption process, which helps to improve the air temperature in the coiled material covering layer and further avoid the formation and development of frozen soil. The heat preservation coiled material is covered on the moisture absorption coiled material to effectively maintain the temperature of the near-surface soil, preventing frost heaving damage. The present application increases the function of absorbing water in the soil in the near-surface area of the project on the basis of traditional single heat preservation, fundamentally prevents the occurrence of frost heaving disasters, and scientifically and effectively achieves better heat preservation and anti-freezing effect. The near-surface soil layer fully dried by the moisture absorption coiled material becomes part of the entire heat preservation system, further preventing the formation of seasonal frozen soil." However, it focuses on the formation of seasonal frozen soil. In actual engineering, if instantaneous frozen soil occurs, the engineering loss may occur due to untimely arrangement.

[0005] CN112514576A discloses a seasonal frozen soil with an unfreezing type yield increasing pre-embedded rod, and the protected right is "the hollow rod body is buried in the soil, after the soil freezes, the first touch lever group can manually trigger the self-heating storage balloon to pierce the uppermost self-heating storage balloon, the heat generating agent in the self-heating storage balloon can spontaneously release a large amount of heat, the heat can be conducted to the frozen soil through the heat conducting pipe, the pre-heat filling material and the heat conducting rod, so as to thaw the frozen soil, thereby facilitating the migration of water in the soil, and further helping the growth of crops and improving the yield of crops. The anti-mis-touch slide bar and the anti-mis-touch block in the first touch lever group can effectively prevent mis-touch, and through the setting of the interval touch separation plate and the combination of the heat conducting pipe in the self-heating storage balloon, the frozen soil can be automatically thawed after a certain interval.

[0006] In summary, the existing anti-frozen soil structure and construction method has the following defects: the frozen soil problem makes the slope more fragile, and greatly restricts the recovery of the ecological environment; the traditional anti-frozen soil structure and construction method has a complex process, requires a large amount of materials and manpower, and cannot meet the water requirements of vegetation growth, therefore, an ecological slope protection full-automatic intelligent irrigation system with base material water supplement and anti-freezing functions is urgently needed to solve the above problems. SUMMARY

[0007] To solve the above technical problems, the present application provides an ecological slope protection full-automatic irrigation system and method, which combines the ground heating system and the drip irrigation system, and has the functions of base material water supplement and anti-freezing. The slope is monitored by the multi-probe temperature and humidity transmitter, different instructions are sent to the electric heater and the variable frequency constant pressure water pump, and the water supplement function and the anti-freezing function of the base material are coordinated.

[0008] In order to realize the above technical features, the purpose of the present application is realized as follows: an ecological slope protection full-automatic irrigation system, comprising an electric heater arranged at the top of the slope and a multi-probe temperature and humidity transmitter, the electric heater is connected with the hose of the slope, and is connected with the filter, the fertilizer tank, the variable frequency constant pressure water pump and the water storage tank at the top of the slope through the water pipe; the multi-probe temperature and humidity transmitter monitors the temperature and humidity index of the slope through the probe, and controls the water pump pressure of the variable frequency constant pressure water pump and the opening and closing of the electric heater; the slope hose is provided with a spring pressure emitter, and the spring pressure emitter can set the opening pressure, and the opening and closing of the spring pressure emitter is controlled by controlling the pipeline water pressure.

[0009] The hose is provided with a preset hole for mounting a spring pressure dripper, the spring pressure dripper comprises a water inlet end, an inner pressure thread is arranged on the inner wall of the water inlet end, the inner pressure thread is in threaded transmission cooperation with an outer thread on the outer wall of a water outlet end; a spring device is arranged between the water inlet end and the water outlet end; the spring device is compressed by relative rotation of the outer thread and the inner thread, and then the water outlet pressure of the dripper is set.

[0010] An outer wall of the water outlet end is provided with a pressure scale for showing the compression amount of the spring device, the water outlet pressure of the dripper is set according to the pressure scale on the side of the dripper, so that when the pressure in the hose exceeds the set value, the flowing water pushes away the spring device and flows out from the round hole, realizing automatic control of drip irrigation, and the round hole is arranged on the outer wall of the water outlet end.

[0011] An end of the water outlet end is provided with an anti-blocking net.

[0012] The electric heater is provided with a common water inlet, a rotating water outlet and a rotating water inlet, the common water inlet is connected with a water supply system, and the rotating water outlet and the rotating water inlet are respectively connected with two ends of the hose on the slope surface.

[0013] The electric heater is provided with an anchor rod fixing hole, the anchor rod passes through the anchor rod fixing hole and fixes the electric heater on the slope top.

[0014] The system further comprises a control system, the control system comprises a controller, a signal input end of the controller is connected with a multi-probe temperature and humidity transmitter, and a signal output end of the controller is connected with a variable frequency constant pressure water pump and an electric heater.

[0015] The hose is fixed on the slope surface by hot-rolled steel bars, and the hose is arranged in a spiral and circuitous manner.

[0016] The arrangement spacing of the hose on the slope surface is arranged according to actual engineering needs, and a circulating arrangement mode is adopted, so that the two ends of the hose are respectively connected with the rotating water outlet and the rotating water inlet.

[0017] An operation method of an ecological slope protection full-automatic irrigation system, comprising the following steps:

[0018] Step one: according to relevant engineering specifications, the slope surface of the slope to be repaired is pretreated and the arrangement of the reinforcing system is arranged; the length and spacing of the hose are determined according to the size of the slope and the growth of the plants;

[0019] Step two: the hose is arranged on the reinforcing system of the slope surface in a spiral and circuitous manner, and the hose is fixed by hot-rolled steel bars;

[0020] Step 3: Set the water pressure of the spring pressure dripper. The construction worker holds the water inlet end with one hand and rotates the water outlet end of the dripper with the other hand, so that the external and internal threads rotate relative to each other, causing the spring device to compress accordingly. At the same time, refer to the pressure scale on the side of the dripper to set the dripper pressure. Place the set spring pressure dripper into the preset hole of the hose. Then, spray the base layer and surface layer of the slope with vegetation cement to completely cover the hose.

[0021] Step 4: Install the electric heater at the top of the slope, and use anchor rods to pass through the anchor rod fixing holes on the base of the electric heater to fix the electric heater on the slope. Connect the rotating water outlet and rotating water inlet to the slope hose.

[0022] Step 5: Connect the water storage tank, variable frequency constant pressure water pump, fertilizer tank and filter in sequence with water pipes at the top of the slope, and finally connect to the ordinary water inlet of the electric heater. After the variable frequency constant pressure water pump is turned on, cooperate with the opening and closing of the water pipe gate valve and the fertilizer tank gate valve to selectively deliver water or water fertilizer to the hose on the slope.

[0023] Step Six: Install a multi-probe temperature and humidity transmitter at the top of the slope, bury the probes in the slope location to be monitored, and connect the multi-probe temperature and humidity transmitter wirelessly to the electric heater and the variable frequency constant pressure water pump. Use the slope temperature and humidity data obtained by the multi-probe temperature and humidity transmitter to control the water pump pressure of the variable frequency constant pressure water pump and the opening and closing of the electric heater.

[0024] Step 7: When the multi-probe temperature and humidity transmitter senses that the lowest temperature T of the slope is less than or equal to 0℃ and the highest moisture content W is greater than or equal to the initial frost heave moisture content W1, it sends a signal to the controller. The controller controls the electric heater and the variable frequency constant pressure water pump, so that the electric heater is turned on, the variable frequency constant pressure water pump is turned on at the set low pressure P1, the water pipe water circulation system is turned on, and the spring pressure dripper is turned off.

[0025] When the multi-probe temperature and humidity transmitter senses that the lowest slope temperature T is less than or equal to 0℃ and the highest moisture content W is lower than the initial frost heave moisture content W1, the controller sends a signal to the electric heater and the variable frequency constant pressure water pump to keep the entire system shut down.

[0026] When the multi-probe temperature and humidity transmitter senses that the minimum slope temperature T is higher than 0℃ and the minimum moisture content W' is less than or equal to the minimum moisture content W2 for plant survival, the controller sends a signal to the electric heater and the variable frequency constant pressure water pump, causing the electric heater to turn off, the variable frequency constant pressure water pump to turn on at the set high pressure P2, the water pipe circulation system to turn on, and the spring pressure dripper to turn on.

[0027] When the multi-probe temperature and humidity transmitter senses that the slope temperature T is higher than 0℃ and the minimum moisture content W' is higher than the minimum moisture content W2 for plant survival, it sends a signal to the electric heater and the variable frequency constant pressure water pump to keep the entire system shut down.

[0028] The present invention has the following beneficial effects:

[0029] 1. This invention combines a floor heating system and a drip irrigation system, providing both substrate hydration and freeze protection. By monitoring the slope using a multi-probe temperature and humidity transmitter, different commands are sent to the heater and the variable frequency constant pressure water pump, thus coordinating the substrate hydration and freeze protection functions.

[0030] 2. By setting different pressures for the spring-pressure dripper, automatic control of the dripper's opening and closing under varying water pressures is achieved. Different slope conditions in different projects lead to variations in pipeline layout, resulting in different water circulation pressures within the pipeline. Therefore, the opening pressure of the dripper varies from project to project. The spring-pressure dripper can be set with pressure according to the specific project, meeting the needs of different working conditions. Furthermore, the spring-pressure dripper is equipped with an anti-clogging mesh structure, effectively preventing the dripper from being blocked by soil, making it more suitable for seepage irrigation compared to ordinary drippers.

[0031] 3. By setting a rotating inlet and outlet in the electric heater, the use of components such as bends and elbows at the connection between the electric heater and the slope water pipe is reduced, which facilitates the connection between the electric heater and the water pipe. In addition, the rotatability of the rotating inlet and outlet reduces the stress concentration at the connection between the electric heater and the slope water pipe, which is beneficial to the long-term use of the interface.

[0032] 4. When performing substrate water replenishment and antifreeze protection on slopes, this invention effectively simplifies the repair process and construction technology, reduces the required manpower and material costs, and achieves automated management of slope water replenishment and antifreeze through the coordination of electric heaters and variable frequency constant pressure water pumps by multi-probe temperature and humidity transmitters.

[0047] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0048] Example 1:

[0049] See Figures 1-8 An automated irrigation system for ecological slope protection includes an electric heater 6 and a multi-probe temperature and humidity transmitter 7 located at the top of the slope. The electric heater 6 is connected to a flexible hose 8 on the slope 1, and is connected via water pipes to a filter 5, a fertilizer tank 4, a variable frequency constant pressure water pump 3, and a water storage tank 2 at the top of the slope. The multi-probe temperature and humidity transmitter 7 monitors the temperature and humidity indicators of the slope 1 through probes 7.1, and controls the water pressure of the variable frequency constant pressure water pump 3 and the opening and closing of the electric heater 6. The flexible hose 8 on the slope is equipped with a spring pressure dripper 8.1, which can be set with an opening pressure. The opening and closing of the spring pressure dripper 8.1 is controlled by controlling the water pressure in the pipeline. This invention combines a floor heating system and a drip irrigation system, providing both substrate water replenishment and antifreeze functions. By monitoring the slope through the multi-probe temperature and humidity transmitter, different commands are issued to the electric heater and the variable frequency constant pressure water pump, achieving coordination between the substrate water replenishment and antifreeze functions. During operation, the temperature and humidity of the slope 1 are monitored by probe 7.1. The temperature and humidity are compared with the set parameters to provide feedback for adjusting the electric heater 6 and the variable frequency constant pressure water pump 3, thereby achieving temperature regulation and control as well as opening and closing control of the spring pressure dripper 8.1.

[0050] Furthermore, the flexible hose 8 is provided with a pre-set hole 8.2 for installing a spring pressure dripper 8.1. The spring pressure dripper 8.1 includes a water inlet end 8.1.4, and an internal pressure thread 8.1.6 is provided on the inner wall of the water inlet end 8.1.4. The internal pressure thread 8.1.6 and the external thread 8.1.5 on the outer wall of the water outlet end 8.1.3 form a threaded transmission engagement. A spring device 8.1.1 is provided between the water inlet end 8.1.4 and the water outlet end 8.1.3. The relative rotation of the external thread 8.1.5 and the internal thread 8.1.6 causes the spring device 8.1.1 to be compressed accordingly, thereby setting the dripper's outlet pressure. The spring pressure dripper 8.1 can achieve the purpose of pressure opening and closing. By pre-setting the opening pressure, when irrigation is needed, it is only necessary to control the water pressure to be greater than the opening pressure of the spring device 8.1.1 to discharge irrigation water or fertilizer through the water outlet end 8.1.3 to achieve the purpose of irrigation.

[0051] When pressure needs to be set, the construction worker holds the inlet end 8.1.4 with one hand and rotates the outlet end 8.1.3 of the dripper with the other hand, so that the external thread 8.1.5 and the internal thread 8.1.6 rotate relative to each other, causing the spring device 8.1.1 to be compressed accordingly. At the same time, the dripper pressure is set with reference to the pressure scale 8.1.2 on the side of the dripper.

[0052] Furthermore, a pressure scale 8.1.2 for displaying the compression of the spring device 8.1.1 is provided on the outer wall of the water outlet 8.1.3. The water pressure of the dripper is set according to the pressure scale 8.1.2 on the dripper side. When the pressure in the hose 8 exceeds the set value, the water flows out through the round hole 8.1.7, breaking the spring device 8.1.1, thus achieving automatic control of drip irrigation. The round hole 8.1.7 is located on the outer wall of the water outlet 8.1.3. The aforementioned pressure scale 8.1.2 facilitates the display and control of the opening pressure.

[0053] Furthermore, an anti-clogging net 8.1.8 is provided at the end of the water outlet 8.1.3. The anti-clogging net 8.1.8 can effectively prevent the water outlet 8.1.3 from becoming blocked due to being buried inside the slope.

[0054] Furthermore, the electric heater 6 is equipped with a standard water inlet 6.1, a rotating water outlet 6.2, and a rotating water inlet 6.3. The standard water inlet 6.1 is connected to the water supply system; the rotating water outlet 6.2 and the rotating water inlet 6.3 are respectively connected to both ends of the flexible hose 8 on the surface of the slope 1. The electric heater 6 described above can be used to circulate and heat water to achieve the purpose of temperature control of the slope.

[0055] Furthermore, the heater 6 is provided with anchor bolt fixing holes 6.4, through which anchor bolts 6.5 pass and fix the heater 6 to the top of the slope. This fixing method ensures the reliability of the heater 6's fixation.

[0056] Furthermore, the system also includes a control system, which comprises a controller. The signal input terminal of the controller is simultaneously connected to the multi-probe temperature and humidity transmitter 7; the signal output terminal of the controller is connected to the variable frequency constant pressure water pump 3 and the electric heater 6. This control system enables automatic control of the entire irrigation system, improving its automation and intelligence levels.

[0057] Furthermore, the flexible hose 8 is fixed to the slope by hot-rolled steel bars 8.6, and the hose 8 is arranged in a spiral, meandering pattern. The spacing of the hose 8 on the slope is arranged according to the actual needs of the project, and a circulating arrangement is adopted so that the two ends of the hose 8 are respectively connected to the rotating outlet 6.2 and the rotating inlet 6.3. Through the above-mentioned fixing and installation method of the hose 8, the reliability of its fixation is ensured, while ensuring the circulating heating effect of the irrigation water.

[0058] Example 2:

[0059] A method for operating a fully automated irrigation system for ecological slope protection includes the following steps:

[0060] Step 1: According to the "Technical Specification for Construction of Vegetated Cement-Soil Habitat for Hydropower Projects", the slope surface to be repaired is pretreated and the reinforcement system is arranged; the length and spacing of the flexible hose 8 are determined according to the slope size and plant growth.

[0061] Step 2: Arrange the flexible hose 8 on the slope reinforcement system in a spiral and meandering manner, and fix the flexible hose 8 with hot-rolled steel bars 8.6;

[0062] Step 3: Set the water pressure of the spring pressure dripper 8.1. The construction worker holds the inlet end 8.1.4 with one hand and rotates the outlet end 8.1.3 of the dripper with the other hand, so that the external thread 8.1.5 and the internal thread 8.1.6 rotate relative to each other, so that the spring device 8.1.1 is compressed accordingly. At the same time, refer to the pressure scale 8.1.2 on the side of the dripper to set the dripper pressure. Place the set spring pressure dripper 8.1 into the preset hole 8.2 of the hose 8. Then spray the base layer and surface layer of the slope with vegetated cement, so that the vegetated cement completely covers the hose 8.

[0063] Step 4: Install the electric heater 6 at the top of the slope, and use the anchor rod 6.5 to pass through the anchor rod fixing hole 6.4 on the base of the electric heater 6 to fix the electric heater 6 on the slope. Connect the rotating water outlet 6.2 and the rotating water inlet 6.3 to the slope hose 8.

[0064] Step 5: Connect the water storage tank 2, the variable frequency constant pressure water pump 3, the fertilizer tank 4 and the filter 5 in sequence with water pipes at the top of the slope, and finally connect them to the ordinary water inlet 6.1 of the electric heater 6. After the variable frequency constant pressure water pump 3 is turned on, it will work with the water pipe gate valve and the fertilizer tank gate valve to selectively deliver water or water fertilizer to the hose 8 of the slope 1.

[0065] Step 6: Install a multi-probe temperature and humidity transmitter 7 at the top of the slope, and bury the probes 7.1 in the slope location to be monitored. The multi-probe temperature and humidity transmitter 7 is wirelessly connected to the electric heater 6 and the variable frequency constant pressure water pump 3. The water pump pressure of the variable frequency constant pressure water pump 3 and the opening and closing of the electric heater 6 are controlled by the slope temperature and humidity data obtained by the multi-probe temperature and humidity transmitter 7.

[0066] Example 3:

[0067] See Figure 1 This invention provides a specific method for controlling temperature and humidity during the irrigation process.

[0068] When the multi-probe temperature and humidity transmitter 7 senses that the lowest temperature T of the slope is less than or equal to 0℃ and the highest moisture content W is greater than or equal to the initial frost heave moisture content W1, it sends a signal to the controller. The controller controls the electric heater 6 and the variable frequency constant pressure water pump 3, so that the electric heater 6 is turned on, the variable frequency constant pressure water pump is turned on at the set low pressure P1, the water pipe water circulation system is turned on, and the spring pressure dripper 8.1 is turned off.

[0069] When the multi-probe temperature and humidity transmitter 7 senses that the lowest slope temperature T is less than or equal to 0℃ and the highest moisture content W is lower than the initial frost heave moisture content W1, the controller sends a signal to the electric heater 6 and the variable frequency constant pressure water pump 3 to keep the entire system shut down.

[0070] When the multi-probe temperature and humidity transmitter 7 senses that the minimum slope temperature T is higher than 0℃ and the minimum moisture content W' is less than or equal to the minimum moisture content W2 for plant survival, the controller sends a signal to the electric heater 6 and the variable frequency constant pressure water pump 3, causing the electric heater to turn off, the variable frequency constant pressure water pump to turn on at the set high pressure P2, the water pipe circulation system to turn on, and the spring pressure dripper 8.1 to turn on.

[0071] When the multi-probe temperature and humidity transmitter 7 senses that the slope temperature T is higher than 0℃ and the minimum moisture content W' is higher than the minimum moisture content W2 for plant survival, it sends a signal to the electric heater 6 and the variable frequency constant pressure water pump 3 to keep the entire system shut down.
