However, for alpine forests, there are problems such as difficult mountain roads and complex forest environmental conditions, so existing irrigation devices are not applicable. Summary of the invention

[0003] In view of the deficiencies in the prior art, the object of the present invention is to provide an irrigation system for alpine forests to solve the problem that the existing irrigation devices in the prior art are not suitable for irrigation of alpine forests.

[0004] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: an irrigation system for alpine forest land, comprising a water supply unit and a monitoring unit coordinated therewith;

[0005] The water supply unit includes a low-level water storage tank, a low-level fertilizer storage box, a high-level water storage tank, a high-level fertilizer storage box and a plurality of spray pipelines. The low-level water storage tank and the low-level fertilizer storage box are both arranged at the foot of the alpine forest, and the high-level water storage tank and the high-level fertilizer storage box are arranged at a high position in the alpine forest. The low-level water storage tank, the low-level fertilizer storage box, the high-level water storage tank and the high-level fertilizer storage box are connected through a feeding pipeline assembly, and the high-level water storage tank, the high-level fertilizer storage box and the plurality of spray pipelines are connected through a liquid outlet pipeline assembly, and the plurality of spray pipelines are distributed in the alpine forest;

[0006] The monitoring unit includes a soil nutrient detector and a soil moisture meter that are arranged in conjunction with each spray pipeline, a high liquid level meter and a low liquid level meter that are arranged in a high-level water storage tank and a high-level fertilizer storage box, and a controller that is connected to the soil nutrient detector, the soil moisture meter, the high liquid level meter, the low liquid level meter, the feeding pipeline assembly, and the liquid outlet pipeline assembly. The controller combines the detection data of the soil nutrient detector, the soil moisture meter, the high liquid level meter, and the low liquid level meter to control the feeding pipeline assembly, the liquid outlet pipeline assembly, and the spray pipeline status to control the water replenishment status of the high-level water storage tank, the water replenishment or liquid fertilizer status of the high-level fertilizer storage box, or the spraying status of the spray pipeline.

[0007] Technical principle:

[0008] When the low liquid level gauge in the high-level water storage tank detects that the liquid level in the high-level water storage tank is low, the controller connects the feeding pipeline assembly between the low-level water storage tank and the high-level water storage tank and replenishes water into the high-level water storage tank, until the high liquid level gauge in the high-level water storage tank detects that the liquid level in the high-level water storage tank reaches the high liquid level, and the feeding pipeline assembly is disconnected to stop replenishing water into the high-level water storage tank; when the soil humidity meter detects that the humidity in the soil in the alpine forest is lower than the preset humidity value, the controller connects the liquid outlet pipeline assembly between the high-level water storage tank and a plurality of spray pipelines, and transports the water in the high-level water storage tank to a plurality of spray pipelines for spraying, so as to replenish water into the soil in the alpine forest, and after the water replenishment is completed, the liquid outlet pipeline assembly is disconnected and closed; When the soil nutrient detector detects that the nutrient value in the soil in the alpine forest is lower than the preset nutrient value, the controller connects the feeding pipeline assembly between the low-level fertilizer storage box and the high-level fertilizer storage box and adds liquid fertilizer to the high-level fertilizer storage box. At the same time, the liquid outlet pipeline assembly connects the high-level water storage tank and the high-level fertilizer storage box and adds water to the high-level fertilizer storage box. The water and liquid fertilizer are mixed in the high-level fertilizer storage box. Then the feeding pipeline assembly is disconnected and closed, and the liquid outlet pipeline assembly is connected between the high-level fertilizer storage box and a plurality of spray pipelines. The mixed fertilizer water in the high-level fertilizer storage box is sprayed through a plurality of spray pipelines to supplement fertilizer to the soil in the alpine forest. After the fertilizer supplement is completed, the liquid outlet pipeline assembly is disconnected and closed.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

The controller combines the detection data of the soil nutrient detector, the soil moisture meter 9, the high liquid level meter and the low liquid level meter to control the feeding pipeline assembly 6, the liquid outlet pipeline assembly 7 and the spray pipeline 5 to control the water replenishment state of the high-level water storage tank 3, the water replenishment or liquid fertilizer state of the high-level fertilizer storage tank 4 or the spraying state of the spray pipeline 5.

[0018] When used in this embodiment:

[0019] When the low liquid level gauge in the high-position water storage tank 3 detects that the liquid level in the high-position water storage tank 3 is low, the controller enables the replenishing pipeline assembly 6 to connect between the low-position water storage tank 1 and the high-position water storage tank 3 and replenish water into the high-position water storage tank 3, until the high liquid level gauge in the high-position water storage tank 3 detects that the liquid level in the high-position water storage tank 3 reaches the high liquid level, and the replenishing pipeline assembly 6 is disconnected and stops replenishing water into the high-position water storage tank 3; when the soil humidity meter 9 detects that the humidity in the soil in the alpine forest is lower than the preset humidity value, the controller enables the liquid outlet pipeline assembly 7 to connect between the high-position water storage tank 3 and a plurality of spray pipelines 5, and transports the water in the high-position water storage tank 3 to the plurality of spray pipelines 5 for spraying, so as to replenish water to the soil in the alpine forest, and after the water replenishment is completed, the liquid outlet pipeline assembly 7 is disconnected and closed; When the soil nutrient detector detects that the nutrient value in the soil in the alpine forest is lower than the preset nutrient value, the controller connects the feeding pipeline assembly 6 between the low-position fertilizer storage box 2 and the high-position fertilizer storage box 4 and adds liquid fertilizer to the high-position fertilizer storage box 4. At the same time, the liquid outlet pipeline assembly 7 connects between the high-position water storage tank 3 and the high-position fertilizer storage box 4 and adds water to the high-position fertilizer storage box 4. The water and liquid fertilizer are mixed in the high-position fertilizer storage box 4. Then the feeding pipeline assembly 6 is disconnected and closed, and the liquid outlet pipeline assembly 7 is connected between the high-position fertilizer storage box 4 and a plurality of spray pipelines 5. The mixed fertilizer water in the high-position fertilizer storage box 4 is sprayed through a plurality of spray pipelines 5 to supplement fertilizer to the soil in the alpine forest. After the fertilizer supplement is completed, the liquid outlet pipeline assembly 7 is disconnected and closed.

[0020] Among them, the high-position fertilizer storage box 4 can be equipped with two flow meters connected to the controller, and the two flow meters are used to respectively measure the amount of liquid fertilizer and water added to the high-position fertilizer storage box 4, so that the fertilizer water concentration in the high-position fertilizer storage box 4 meets the requirements of use.

[0021] Furthermore, a stirrer connected to the controller can be rotatably arranged in the high-position fertilizer storage box 4, and the supplemented liquid fertilizer and water can be fully stirred by the stirrer to form a uniformly mixed fertilizer water.

[0022] The irrigation system efficiently irrigates and fertilizes alpine forests through the cooperation of a water supply unit and a monitoring unit, thereby reducing labor costs and the probability of dangerous accidents during irrigation and fertilization of alpine forests. The controller controls the feeding pipeline assembly 6 to connect and feed between the low-level water tank 1 and the high-level water tank 3 or between the low-level fertilizer storage box 2 and the high-level fertilizer storage box 4, and also connects the liquid outlet pipeline assembly 7 between the high-level water tank 3 and the high-level fertilizer storage box 4, between the high-level water tank 3 and a plurality of spray pipelines 5, or between the high-level fertilizer storage box 4 and a plurality of spray pipelines 5, and drives the liquid flow, so as to complete the configuration of fertilizer water, irrigate and fertilize the alpine forests, making the structural layout simple and reasonable.

[0023] In order to better understand this solution, the structure of this solution will be further optimized below.

[0024] like Figure 1 and Figure 2 As shown, according to another embodiment of the present invention, an irrigation system for alpine forest land, wherein the liquid outlet pipeline assembly 7 includes a liquid outlet pump 71, a first liquid inlet pipeline 72 and a first liquid outlet pipeline 73, wherein the liquid outlet pump 71 is connected to a controller; the first liquid inlet pipeline 72 has three first connection ports, wherein one of the first connection ports is connected to the liquid inlet of the liquid outlet pump 71, and the other two first connection ports are connected to the liquid outlet of the high-position fertilizer storage tank 4 and the liquid outlet of the high-position water storage tank 3 in a one-to-one correspondence and are all provided with a controller for controlling their connection status. The first valve 74, the two first valves 74 are both connected to the controller; the first liquid outlet pipeline 73 has three second connection ports, one of which is connected to a liquid distribution pipe 75 connected to a plurality of spray pipelines 5, and the other two second connection ports are connected to the liquid outlet of the liquid outlet pump 71 and the first liquid inlet of the high-position fertilizer storage box 4 in a one-to-one correspondence, and the second connection ports connected to the liquid distribution pipe 75 and the first liquid inlet of the high-position fertilizer storage box 4 are both provided with a second valve 76 for controlling their connection state, and the two second valves 76 are both connected to the controller.

[0025] The feeding pipeline assembly 6 includes a liquid feeding pump 61, a second liquid inlet pipeline 62 and a second liquid outlet pipeline 63, and the liquid feeding pump 61 is connected to the controller; the second liquid inlet pipeline 62 has three third connecting ports, one of which is connected to the liquid inlet of the liquid feeding pump 61, and the other two third connecting ports are connected to the liquid outlet of the low-level fertilizer storage box 2 and the liquid outlet of the low-level water storage tank 1 in a one-to-one correspondence and are both provided with a third valve 64 for controlling their connection state, and the two third valves 64 are both connected to the controller; the second liquid outlet pipeline 63 has three fourth connecting ports, one of which is connected to the liquid outlet of the liquid feeding pump 61, and the other two second connecting ports are connected to the second liquid inlet of the high-level fertilizer storage box 4 and the liquid inlet of the high-level water storage tank 3 in a one-to-one correspondence and are both provided with a fourth valve 65 for controlling their connection state, and the two fourth valves 65 are both connected to the controller.

[0026] Each of the spray pipelines 5 includes a liquid guide tube 51 and an atomizing nozzle 52. The liquid guide tube 51 is arranged in the alpine forest and one end of which is connected to the liquid outlet pipeline assembly 7. A fifth valve 53 connected to the controller is provided on the end of the liquid guide tube 51 connected to the liquid outlet pipeline assembly 7. There are several atomizing nozzles 52 and they are all connected to the liquid guide tube 51. The several atomizing nozzles 52 are distributed at intervals along the length direction of the liquid guide tube 51.

[0027] In this embodiment, the first liquid inlet pipeline 72, the first liquid outlet pipeline 73, the second liquid inlet pipeline 62 and the second liquid outlet pipeline 63 are all three-way pipes, dividing the alpine forest land into several zones, and several spray pipelines 5 are arranged in one zone in a one-to-one correspondence, and the number of soil nutrient detectors and soil moisture meters 9 arranged in each zone is multiple, which is adjusted according to actual conditions; the liquid guide tubes 51 are all connected to the liquid distribution tube 75.

[0028] When the low liquid level gauge in the high-level water tank 3 detects that the liquid level in the high-level water tank 3 is low, this signal is fed back to the controller, and the controller then controls the third valve 64 coordinated with the liquid outlet of the low-level water tank 1 and the fourth valve 65 coordinated with the liquid inlet of the high-level water tank 3 to open, and starts the liquid delivery pump 61 to pump water in the low-level water tank 1 into the high-level water tank 3 for water replenishment, until the high liquid level gauge in the high-level water tank 3 detects that the liquid level in the high-level water tank 3 reaches the high liquid level, and this signal is fed back to the controller, and the controller then controls the above-mentioned third valve 64 and fourth valve 65 to close, and the liquid delivery pump 61 stops running.

[0029] When the soil moisture meter 9 detects that the humidity in the soil of the alpine forest is lower than the preset humidity value, this signal is fed back to the controller, and then the controller controls the first valve 74 matched with the liquid outlet of the high-level water storage tank 3, the second valve 76 matched with the liquid distribution pipe 75, and each fifth valve 53 to open, and starts the liquid outlet pump 71 to guide the water in the high-level water storage tank 3 into each liquid guide pipe 51, and then spray it out through the atomizing nozzle 52 to replenish water to the soil of the alpine forest; the timing of completing the water replenishment can be controlled according to the preset single water replenishment amount and other methods. When the water replenishment is completed, the controller controls the above-mentioned first valve 74, the second valve 76 and the fifth valve 53 to be closed, and the liquid outlet pump 71 is stopped. Of course, if it is detected that some areas in the alpine forest need water replenishment, it can be operated in the above manner, and the fifth valve 53 matched with the area that does not need water replenishment remains closed, so that the area that needs water replenishment can be selectively replenished.

[0030] When the soil nutrient detector detects that the nutrient value in the soil in the alpine forest is lower than the preset nutrient value, this signal is fed back to the controller, and the controller then controls the third valve 64 matched with the liquid outlet of the low-level fertilizer storage box 2 and the fourth valve 65 matched with the second liquid inlet of the high-level fertilizer storage box 4 to open, and starts the liquid delivery pump 61 to draw the liquid fertilizer in the low-level fertilizer storage box 2 into the high-level fertilizer storage box 4 for replenishing the liquid fertilizer; at the same time, it also controls the first valve 74 matched with the liquid outlet of the high-level water storage tank 3 and the second valve 76 matched with the first liquid inlet of the high-level fertilizer storage box 4 to open, and starts the liquid delivery pump 71 to allow the high-level water storage tank 3 to replenish the liquid fertilizer in the high-level fertilizer storage box 4. Water; wherein, the amount of liquid fertilizer and water added to the high-position fertilizer storage box 4 is detected by the corresponding flow meter. When the flow meter detects that the amount of liquid fertilizer or water added reaches the preset amount, the signal is fed back to the controller, and then the corresponding valve is controlled to close and the corresponding pump is stopped; the controller then drives the agitator to run, and the agitator stops running after running for a preset stirring time; then the controller controls the first valve 74 matched with the liquid outlet of the high-position fertilizer storage box 4, the second valve 76 matched with the liquid distribution pipe 75, and each fifth valve 53 to open, and starts the liquid outlet pump 71 to spray the evenly mixed fertilizer water in the high-position fertilizer storage box 4 into the alpine forest. Similarly, the timing of completing the fertilizer water replenishment can be controlled according to the preset single fertilizer water volume and other methods. When the fertilizer water replenishment is completed, the controller controls the above-mentioned first valve 74, the second valve 76 and the fifth valve 53 to close, and stops the liquid outlet pump 71. Of course, if it is detected that some areas in the alpine forest need to be supplemented with fertilizer water, the above-mentioned method can be used, and the fifth valve 53 of the areas that do not need fertilizer water can be kept closed, so that fertilizer water can be selectively supplemented to the areas that need fertilizer water.

[0031] Specifically, the data detected by multiple soil nutrient detectors and multiple soil moisture meters 9 in each zone can be averaged and then compared with the preset nutrient value and preset humidity value to determine whether water or fertilizer water is needed. The controller can be connected to a display or a mobile phone to facilitate clear viewing of the detected data at all times.

[0032] Since the soil moisture meter 9 is installed in the alpine forest to detect the soil moisture in the alpine forest, if the probe of the soil moisture meter 9 is always inserted into the soil in the alpine forest, its detection accuracy will be greatly affected during long-term use; in order to enable the soil moisture meter 9 to maintain good detection accuracy, such as Figure 3 As shown, according to another embodiment of the present invention, an irrigation system for alpine forest land, wherein the soil moisture meter 9 is equipped with a supporting and protecting mechanism 8 for installing and protecting it, and the supporting and protecting mechanism 8 is connected to a controller to drive the probe of the soil moisture meter 9 to be regularly inserted into the soil of the alpine forest land for detection.

[0033] Based on the above scheme:

[0034] The support and protection mechanism 8 includes a support frame 81, a mounting cover 82 and a linear drive 83. The bottom of the support frame 81 is inserted into the soil of the alpine forest and fixed; the mounting cover 82 is detachably connected to the support frame 81, and two sealing doors 85 that are sealed to each other are rotatably connected at the bottom opening of the mounting cover 82; the linear drive 83 is fixedly arranged at the top of the mounting cover 82 and connected to the controller, and the output end of the bottom of the linear drive 83 is connected to the soil moisture meter 9 through the mounting seat 84, and the probe of the soil moisture meter 9 faces the bottom opening of the mounting cover 82, and two push rods 86 are connected to the mounting seat 84, and the two push rods 86 are against the two sealing doors 85 in a one-to-one correspondence.

[0035] In this embodiment, the linear driver 83 can be fixedly connected to the inner wall of the mounting cover 82 by using multiple screws, and the output end of the linear driver 83 can be connected to the mounting seat 84 by threads. The mounting seat 84 is provided with a connection groove, and the soil moisture meter 9 is partially embedded in the connection groove and fixed by multiple bolts, so as to facilitate the installation and disassembly of the soil moisture meter 9 and the linear driver 83. The linear driver 83 can be a cylinder; the sealing door 85 and the side wall of the bottom opening of the mounting cover 82 can be connected by an existing rotating connection structure, such as a matching torsion spring and a rotating shaft, so that the two sealing doors 85 can cooperate to stably seal the bottom opening of the mounting cover 82. When not in use, the linear driver 83 and the soil moisture meter 9 are arranged in a relatively closed environment in the mounting cover 82, so as to improve the safety of the linear driver 83 and the soil moisture meter 9. When the preset humidity detection time is reached, the controller controls the linear drive 83 to operate, and the mounting seat 84 moves downward together with the output end of the linear drive 83, driving the two push rods 86 to correspond to the two sealing doors 85 one by one to drive the two sealing doors 85 to rotate, and the bottom opening of the mounting cover 82 is opened. At the same time, the soil moisture meter 9 moves downward together with the mounting seat 84, and the probe of the soil moisture meter 9 passes through the bottom opening of the mounting cover 82 and is inserted into the soil of the alpine forest. The rear controller starts the soil moisture meter 9, and the soil moisture meter 9 detects the humidity in the soil, and the detected data is fed back to the controller; the rear controller controls the linear drive 83 to run in the reverse direction, and the mounting seat 84 moves upward together with the output end of the linear drive 83, and the soil moisture meter 9 and the push rod 86 move upward together with the mounting seat 84 until the soil moisture meter 9, the push rod 86 and the linear drive 83 are reset, and the two sealing doors 85 gradually rotate in the opposite direction to seal the bottom opening of the mounting cover 82 again.

[0036] Among them, a cleaning ring 87 is fixedly installed in the bottom opening of the mounting cover 82, and a number of flexible bristles are evenly distributed on the inner wall of the cleaning ring 87. The central axis of the cleaning ring 87 coincides with the central axis of the probe of the soil moisture meter 9, and the probe of the soil moisture meter 9 can freely pass through the cleaning ring 87.

[0037] When the probe of the soil moisture meter 9 passes through the bottom opening of the mounting cover 82 or passes back into the mounting cover 82, the probe of the soil moisture meter 9 passes through the cleaning ring 87, and the soil adhered to the probe of the soil moisture meter 9 is cleaned by a number of flexible bristles, which is beneficial to improving the detection accuracy of the soil moisture meter 9.

[0038] Furthermore, the support frame 81 is provided with a mounting hole in the vertical direction, and a countersunk hole is formed by extending the bottom end of the mounting hole to the outside thereof. The mounting cover 82 passes through the mounting hole from the bottom end thereof and is positioned in the countersunk hole by a positioning block 88 connected to the outer wall of the mounting cover 82. Here, the positioning block 88 cooperates with the countersunk hole to improve the assembly accuracy of the mounting cover 82 on the support frame 81, and the mounting cover 82 and the support frame 81 can be locked and fixed by a plurality of screws. Among them, the bottom of the support frame 81 has two implantation rods arranged opposite to each other, and the two implantation rods are inserted into the soil of the alpine forest for stable installation.

[0039] It should be noted that the soil nutrient detector can also be installed using the above-mentioned supporting and protecting mechanism 8, and the soil nutrient detector, soil moisture meter 9 and controller in this solution are all existing electrical structures, which will not be further described here.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
