Description

Technical Field

[0001] The present invention relates to the technical field of farmland irrigation, and in particular to a comprehensive monitoring platform for farmland irrigation water efficiency. Background Art

[0002] In farmland irrigation, technologies such as sprinkler irrigation, drip irrigation, micro-sprinkler irrigation and low-pressure pipeline water supply surface irrigation are widely used. Among them, the sprinkler irrigation method mainly involves laying a main water pipe, and then setting up multiple branch pipes on the main water pipe, and irrigating the crops in the farmland through the nozzles of the branch pipes.

[0003] However, the nozzles on existing sprinkler irrigation systems are easily clogged by sediment, algae or chemical precipitation in the water, and fixed-connected sprinklers require cutting off the main water supply before cleaning, which is complicated to operate and affects irrigation in other areas. At the same time, when a single sprinkler is damaged, the main water supply needs to be shut down for maintenance, resulting in long system downtime and high maintenance costs. In addition, existing sprinkler irrigation systems are pre-laid. When crops are only planted in part of the area, the pre-laid sprinkler irrigation system will irrigate the unplanted area, resulting in a mismatch between the irrigation coverage area and the crop water demand area, resulting in a waste of water resources. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a comprehensive monitoring platform for farmland irrigation water efficiency.

[0005] The technical solution is as follows:

[0006] A comprehensive monitoring platform for farmland irrigation water efficiency includes a base frame, a water and fertilizer integrated machine is fixedly connected to the top of the base frame, a water pump is fixedly connected to the top of the base frame, and an irrigation component is arranged at the bottom of the water pump;

[0007] The irrigation assembly includes a main water pipe fixedly connected to the bottom of the water pump, a plurality of branch water pipes fixedly connected to the upper portion of the main water pipe, a joint pipe threadedly connected to each branch water pipe, the inner side wall of the joint pipe is fixedly connected to a fixing platform, a sealing ring is fixedly connected to the bottom of the fixing platform, a water pipe is slidably connected to the inside of the fixing platform, a plurality of strip holes are provided on the outer surface of the bottom of the water pipe, a plurality of mounting holes are provided on the top of the fixing platform, a plurality of springs are fixedly connected between the bottom of the water pipe and the mounting holes, a fixing shell is threadedly connected to the top of the joint pipe, and a sprinkler pipe is fixedly connected to the inside of the fixing shell.

[0008] Furthermore, the integrated water and fertilizer machine is provided with a device for storing and mixing water and fertilizer, and an air pump is provided inside the integrated water and fertilizer machine.

[0009] Furthermore, the main water pipe is connected to the bottom of the water-fertilizer integrated machine, the branch water pipe is connected to the main water pipe, and a circular ring plate is fixedly connected to the top of the outer surface of the water pipe.

[0010] Furthermore, a sealing gasket is fixedly connected to the bottom of the water pipe, a gap is left between the sealing gasket of the water pipe and the inner wall of the joint pipe, the bottom of the nozzle pipe is adapted to the shape of the top of the water pipe, and the top of the nozzle pipe passes through the fixed shell.

[0011] Furthermore, an injection assembly is provided at the bottom of the water and fertilizer integrated machine, and the injection assembly includes a main air pipe fixedly connected to the bottom of the water and fertilizer integrated machine, a plurality of bronchial tubes are fixedly connected to the main air pipe, and a ventilation pipe is fixedly connected to the nozzle pipe, and the end of the ventilation pipe away from the nozzle pipe is clamped with the bronchial tube.

[0012] Furthermore, the main air pipe is connected to the air pump of the water and fertilizer integrated machine, the position of the bronchial pipe corresponds to the branch water pipe, the ventilation pipe is connected to the inside of the nozzle pipe, the ventilation pipe is connected to the bronchial pipe, the ventilation pipe is a hose, and a one-way valve is provided at the connection between the ventilation pipe and the nozzle pipe.

[0013] Furthermore, a monitoring component is provided between the main water pipe and the main air pipe, a connecting frame is fixedly connected between the main water pipe and the main air pipe, and a flow monitoring device is fixedly connected to one end of the connecting frame located inside the water injection pipe.

[0014] Furthermore, one end of the connecting frame penetrates into the interior of the main water pipe, and the flow monitoring device is located inside the main water pipe.

[0015] As described above, the beneficial effects of the comprehensive monitoring platform for farmland irrigation water efficiency in the present invention are as follows:

[0016] By removing the corresponding sprinkler pipes in areas that do not need irrigation, automatic sealing can be achieved, which can directly cut off the water supply to the area, preventing water from being sprayed to places that do not need irrigation, reducing ineffective water use, and improving water resource utilization. At the same time, the design of detachable sprinkler pipes allows for quick adjustment of irrigation coverage without the need to re-lay or modify pipes, reducing modification costs and time;

[0017] The detachable nozzle design facilitates cleaning, replacement, and maintenance. Combined with the self-sealing design of the water pipe, there's no need to shut down the entire main water pipe. This reduces the time required for repairs and cleaning, and minimizes the impact on the overall plumbing plan, compared to existing fixed nozzles that require shutting off the water supply and disassembling the pipe.

[0018] By injecting air into the nozzle pipe and pressurizing it, the spraying range of water can be controlled. When air is added, the spraying range can be increased, and when air is not added, the spraying range can be reduced. At the same time, compared with the existing method of adjusting the water output of the water pump to control the water pressure to control the spraying range, not only will the pressure of the water pipe fluctuate but also waste water resources. By only pressurizing the nozzle pipe, the pressure inside the pipe will not be affected, thereby avoiding aging or rupture of the pipe connection caused by water pressure fluctuations.

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0035] The embodiments provided by the present invention will be described in detail below:

[0036] like Figures 1 to 10 As shown, a comprehensive monitoring platform for farmland irrigation water efficiency includes a base frame 1, a water-fertilizer integrated machine 2 is fixedly connected to the top of the base frame 1, a water pump 3 is fixedly connected to the top of the base frame 1, and an irrigation component for automatically irrigating farmland is provided at the bottom of the water pump 3;

[0037] It should be noted that the water-fertilizer integrated machine 2 is an existing technology, which is a device for storing and mixing water and fertilizer. The water pump 3 can extract the water-fertilizer mixed liquid in the water-fertilizer integrated machine 2, and the built-in controller of the water-fertilizer integrated machine 2 can control the switch of the water pump 3.

[0038] The irrigation assembly includes a main water pipe 41 fixedly connected to the bottom of the water pump 3, the main water pipe 41 is connected to the bottom of the water-fertilizer integrated machine 2, the upper part of the main water pipe 41 is fixedly connected to a plurality of branch water pipes 42 arranged in a linear array, the branch water pipes 42 are connected to the main water pipe 41, each branch water pipe 42 is threadedly connected to a joint pipe 43, the inner side wall of the joint pipe 43 is fixedly connected to a fixed platform 44, the bottom of the fixed platform 44 is fixedly connected to a sealing ring 45, the interior of the fixed platform 44 is slidably connected to a water pipe 46, and the outer surface of the bottom of the water pipe 46 is provided with a ring array. There are multiple strip holes 47 arranged in a circular pattern, a circular plate is fixedly connected to the top of the outer surface of the water pipe 46, and a plurality of mounting holes 481 arranged in a circular array are opened on the top of the fixed platform 44. A plurality of springs 48 are fixedly connected between the bottom of the circular plate of the water pipe 46 and the mounting holes 481. The mounting holes 481 are used to have a contraction space when the springs 48 are compressed, that is, when the water pipe 46 moves downward, the circular plate on it can fit downward to the top of the fixed platform 44. The top of the joint pipe 43 is threadedly connected to a fixed shell 49, and the interior of the fixed shell 49 is fixedly connected to the nozzle pipe 410.

[0039] It should be noted that a sealing gasket is fixedly connected to the bottom of the water pipe 46, and the diameter of the sealing gasket is smaller than the inner diameter of the joint pipe 43, that is, a gap is left between the sealing gasket and the joint pipe 43, so that water can flow upward through the gap between the sealing gasket and the joint pipe 43. The bottom of the nozzle pipe 410 is adapted to the shape of the top of the water pipe 46, so that the water pipe 46 and the nozzle pipe 410 can be effectively plugged in when they are docked. The top of the nozzle pipe 410 passes through the upper part of the fixed shell 49.

[0040] Specifically, when it is necessary to irrigate the farmland, water and fertilizer are added to the water-fertilizer integrated machine 2, and then the water and fertilizer are mixed by the water-fertilizer mixing device in the water-fertilizer integrated machine 2. The water-fertilizer liquid stored in the water-fertilizer integrated machine 2 is extracted by the water pump 3 and then pumped into the main water pipe 41. The water-fertilizer liquid entering the main water pipe 41 will enter the interiors of multiple branch water pipes 42 respectively, and then enter the interior of the joint pipe 43 from the branch water pipe 42. The water-fertilizer liquid entering the joint pipe 43 will continue to flow upward from the gap between the sealing gasket of the water pipe 46 and the joint pipe 43, and then will enter the interior of the water pipe 46 from the strip hole 47. Finally, the liquid entering the water pipe 46 will enter the nozzle pipe 410 and be sprayed out, thereby achieving the effect of automatic irrigation.

[0041] It should be noted that the mixture of water and fertilizer needs to be mixed according to the actual growth conditions of the crops. If it is only for irrigation and watering of crops, then there is no need to add fertilizer. If it is necessary to supplement nutrients for crops, fertilizer can be added and mixed with water.

[0042] In addition, if it is necessary to irrigate a part of the farmland, the nozzle pipe 410 can be disassembled according to the location where irrigation is not required. The initial state can be referred to Figure 7As shown, at this time, the fixed shell 49 is threadedly connected to the joint pipe 43. At this time, the bottom of the nozzle pipe 410 is in conflict with the top of the water pipe 46, so that the water pipe 46 is at the lowest position inside the fixed platform 44. At the same time, the annular plate on the water pipe 46 is in a compressed state against the spring 48. The staff holds the nozzle pipe 410 and rotates the fixed shell 49, so that the fixed shell 49 is gradually loosened from the joint pipe 43. During this process, the fixed shell 49 will gradually move upward. At this time, when the fixed shell 49 moves upward, the water pipe 46 moves upward under the elastic extension action of the spring 48. After the water pipe 46 moves upward, the strip hole 47 will gradually move to the inner side of the fixed platform 44, that is, the strip hole 47 will be blocked by the fixed platform 44 until the fixed shell 49 is disengaged from the threaded connection with the joint pipe 43. After the connection, when the bottom of the nozzle pipe 410 no longer conflicts with the top of the water pipe 46, the elastic extension of the spring 48 makes the sealing gasket at the bottom of the water pipe 46 conflict with the sealing ring 45, thereby sealing the joint pipe 43, so that the liquid in the main water pipe 41 enters the branch water pipe 42, and then cannot continue to flow upward from the branch water pipe 42 into the joint pipe 43. By removing several corresponding nozzle pipes 410 in the area that does not need irrigation, automatic sealing can be achieved at this time, and the water supply to the area can be directly cut off to avoid water spraying to the location that does not need irrigation, reduce ineffective water use, and improve water resource utilization. At the same time, the design of the detachable nozzle pipe 410 allows for rapid adjustment of the irrigation coverage without re-laying or modifying the pipes, reducing modification costs and time.

[0043] It should be noted that if during the irrigation process, the staff finds that a single nozzle pipe 410 is blocked or damaged, that is, the water flow is not smooth, the detachable nozzle pipe 410 design can be easily cleaned or replaced for maintenance. At the same time, the water pipe 46 is designed to be automatically sealed, and there is no need to shut down the entire main water pipe 41. Compared with the existing fixed nozzle pipe 410, which requires cutting off the water source and disassembling the pipe for maintenance, the maintenance and cleaning time is shortened and the impact on the overall pipeline plan is reduced.

[0044] Further explanation, when a new nozzle tube 410 or a nozzle tube 410 that has been cleaned and repaired needs to be reinstalled on the joint tube 43, the staff can hold the fixed shell 49, and then align the bottom of the nozzle tube 410 with the top of the water pipe 46 and plug them together, and then press the fixed shell 49 downward. The fixed shell 49 drives the nozzle tube 410 to push the water pipe 46 to move downward inside the fixed platform 44. The downward movement of the water pipe 46 will compress the spring 48 through the annular plate. At this time, because the bottom of the nozzle tube 410 and the top of the water pipe 46 are aligned and plugged, when the water pipe 46 moves downward, the strip hole 47 leaks out of the interior of the fixed platform 44, and at the same time, the sealing gasket at the bottom of the water pipe 46 no longer conflicts with the sealing ring 45. At this time, the main water After the water in the pipe 41 flows upward through the branch water pipe 42 and into the inside of the joint pipe 43, the water will pass through the gap between the water pipe 46 sealing gasket and the joint pipe 43 and then pass through the strip hole 47 into the inside of the water pipe 46, and finally directly enter the inside of the nozzle pipe 410 and be sprayed out. After the nozzle pipe 410 and the water pipe 46 are plugged in and connected with each other, the problem of water directly spraying out from the water pipe 46 during the installation process is avoided, so that water is only sprayed upward from the nozzle pipe 410. Then the staff continues to press the fixed shell 49. When the fixed shell 49 contacts the joint pipe 43, the fixed shell 49 is rotated so that the fixed shell 49 is threadedly connected to the joint pipe 43. When the fixed shell 49 is tightened on the joint pipe 43, the reinstallation of the nozzle pipe 410 is completed, which is simple and convenient.

[0045] like Figure 1 、 Figure 3 、 Figure 4 and Figure 6 As shown, the bottom of the integrated water and fertilizer machine 2 is provided with an injection assembly for pressurizing the inside of the nozzle pipe 410, and the injection assembly includes a main air pipe 51 fixedly connected to the bottom of the integrated water and fertilizer machine 2, and a plurality of bronchial pipes 52 arranged in a linear array are fixedly connected to the main air pipe 51, and the positions of the bronchial pipes 52 correspond to those of the branch water pipes 42. A vent pipe 53 is fixedly connected to the nozzle pipe 410, and the vent pipe 53 is connected to the inside of the nozzle pipe 410. The end of the vent pipe 53 away from the nozzle pipe 410 is clamped with the bronchial pipe 52, and the vent pipe 53 is connected to the bronchial pipe 52.

[0046] It should be noted that an air pump is provided inside the integrated water and fertilizer machine 2 for collecting gas and pumping it out under pressure. The main air pipe 51 is connected to the air pump of the integrated water and fertilizer machine 2. The middle part of the vent pipe 53 is a hose, and its two ends are hard plastic tubes. The hose part is used to facilitate the disassembly, maintenance or replacement of the nozzle pipe 410, and the hard plastic part at one end is used to facilitate the connection with the bronchial tube 52.

[0047] Specifically, under the action of the air pump inside the water-fertilizer integrated machine 2, gas is pumped into the inside of the main air pipe 51, and the gas enters the inside of the bronchial pipe 52 through the main air pipe 51, and then the gas enters the vent pipe 53 after passing through the bronchial pipe 52, and then the gas enters the inside of the nozzle pipe 410 through the vent pipe 53. The gas entering the inside of the nozzle pipe 410 will pressurize the water in the nozzle pipe 410, that is, the gas-water mixed flow produces an "expansion effect", so that the water can be sprayed to the outside of the nozzle pipe 410 in a high-pressure manner. By this, the spraying range of the water can be adjusted. When aeration is performed, the spraying range can be increased, and when aeration is not performed, the spraying range can be reduced. At the same time, compared with the existing method of adjusting the water output of the water pump 3 to control the water pressure to adjust the spraying range, not only will the pressure of the water pipe fluctuate, but also water resources will be wasted. By only pressurizing the nozzle pipe 410, the pressure inside the pipeline will not be affected, thereby avoiding aging or rupture of the pipeline connection caused by water pressure fluctuations, and at the same time improving the effect of saving water.

[0048] It should be noted that a one-way valve is provided at the connection point between the vent pipe 53 and the nozzle pipe 410. When gas is not injected into the nozzle pipe 410, water entering the nozzle pipe 410 will not enter the interior of the vent pipe 53. When gas is injected, the gas in the vent pipe 53 can be injected into the interior of the nozzle pipe 410 through the one-way valve.

[0049] It needs to be further explained that, since the vent pipe 53 is connected to the nozzle pipe 410, it is necessary to rotate the fixed shell 49 when removing the nozzle pipe 410. At this time, the staff needs to pull out the vent pipe 53 from the bronchial pipe 52 so that the vent pipe 53 is separated from the clamping relationship with the bronchial pipe 52. Then, the fixed shell 49 can be rotated to remove the nozzle pipe 410. Pulling out the vent pipe 53 can turn off the air pump, or the nozzle pipe 410 needs to be cleaned and maintained quickly after removal. The above two methods will only affect the effect of pressurizing other nozzle pipes 410, and will not affect the normal spraying and irrigation effect of other nozzle pipes 410.

[0050] like Figure 3 As shown, a monitoring component for monitoring the water flow in the main water pipe 41 is provided between the main water pipe 41 and the main air pipe 51. A connecting frame 61 is fixedly connected between the main water pipe 41 and the main air pipe 51. One end of the connecting frame 61 penetrates into the interior of the main water pipe 41. The end of the connecting frame 61 located inside the water injection pipe 41 is fixedly connected to a flow monitoring device 62. The flow monitoring device 62 is located inside the main water pipe 41.

[0051] It should be noted that the flow monitoring device 62 is an existing turbine flowmeter that can measure liquid flow. In addition, a display screen is provided on the water-fertilizer integrated machine 2, and the values ​​monitored by the flow monitoring device 62 will be transmitted to the display screen and displayed.

[0052] Specifically, when the water pump 3 pumps water or water-fertilizer into the main water pipe 41, the flow monitoring device 62 can monitor the flow of water or water-fertilizer flowing in the main water pipe 41, and then can monitor the water and water-fertilizer flowing in the main water pipe 41 in real time, thereby monitoring the irrigation water volume, and controlling the water flow through precise data, so that crops can be irrigated more accurately.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
