Description

Technical Field

[0001] The present application relates to the field of irrigation technology, and in particular to an integrated irrigation system. Background Art

[0002] In the process of planting cash crops, due to the uncontrollable factors of climate and weather, technical measures are taken to supplement the water needed by crops. In order to ensure the normal growth of crops and obtain high and stable yields, crops must be supplied with sufficient water. Planting irrigation was born. With the development of science and technology, most of the current planting irrigation has abandoned artificial irrigation and adopted mechanical equipment for irrigation. Relying on the Internet of Things, a smart irrigation system has been developed for intelligent control. For the irrigation of mountainous areas with slopes, due to the slope of the irrigation ground and the different water pressures above and below, the water pressure in the low-lying areas is higher, the irrigation amount is large, and the irrigation amount at the top is less, resulting in uneven irrigation. Whether it is irrigation using water pressure itself or irrigation with water pumps, there is this problem when water is discharged from the top to the bottom, and this situation also exists when water is supplied from the bottom to the top, and the work of the water pump is more. Therefore, this situation has always existed in irrigation. The existing solution is to carry out segmented irrigation, that is, when the irrigation amount of the low-lying part is sufficient, the segmented irrigation is disconnected. The best way is to use valves for segmented control. However, the irrigation area is large and the irrigation waterway is long. If it is done manually, the labor cost is huge.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0050] In view of the above problems, an embodiment of the present application provides an integrated irrigation system. The technical solution of the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0051] like Figure 1 An integrated irrigation system shown includes: a water pool 1, a main water pipe 2, a branch water pipe 3, a water pump 4, a pressure sensor 5, and a flow-limiting water valve 6;

[0052] The bottom of the pool 1 is connected to a main water pipe 2, a plurality of branch water pipes 3 are connected to the main water pipe 2, flow limiting valves 6 are arranged in sections on the branch water pipes 3, and a water pump 4 and a pressure sensor 5 are connected to the main water pipe 2.

[0053] In the present application, the water in the pool 1 is pumped out by the water pump 4 and distributed to the branch water pipe 3. The branch water pipe 3 is connected with a nozzle to complete irrigation. The pressure sensor 5 monitors the water pressure in the main water pipe 2 in real time, and the flow-limiting water valve 6 is arranged in sections on the branch water pipe 3. Because it is used on a slope, the flow rate of the nozzle at the bottom is faster and the irrigation water is more. When it reaches a certain amount of spraying irrigation, the flow-limiting water valve 6 automatically starts to limit its water flow rate and spraying amount. In this way, the pressure at the flow-limiting water valve 6 of the upper section returns to the original pressure at the bottom due to the activation of the flow-limiting water valve 6 of the next section, and the water flow is sprayed out quickly for irrigation, and this is done until the last flow-limiting water valve 6 starts to spray. In this process, the water pressure in the main water pipe 2 will change, and it is necessary to adjust the pumping rate or pressure of the water pump 4 through the detection of the pressure sensor 5 so that it can balance the overall system pressure when the flow-limiting water valve 6 is started. Therefore, a unified controller can be set if necessary to control it through programming.

[0054] In the present application, the flow limiting water valve 6 is a key component. Since the present application does not use electric control but drives and controls by water pressure, Figure 2 and Figure 3 As shown, the present application discloses a purely mechanical flow-limiting water valve 6 including a water inlet end 61, a water supply valve cover 62, a water outlet end 63, a valve body 64, and a water supply valve cover 65; wherein the valve body 64 is arranged in a cylindrical shape, an inlet and outlet water cavity is constructed at the top of the valve body 64 for water to flow in and out, a transmission component cavity 642 is constructed at the bottom for component setting, and a pressure chamber 641 is constructed at the side for control; the water supply valve cover 62 is covered on the inlet and outlet water cavity, the water inlet end 61 is arranged at one end of the inlet and outlet water cavity, the water outlet end 63 is arranged at the other end of the inlet and outlet water cavity, and the pressure chamber 641 is connected to the water inlet end 61.

[0055] Specifically, a water wheel is provided in the water inlet and outlet cavity, and the rotating shaft of the water wheel passes through the water inlet and outlet cavity and is located in the transmission component cavity 642. In this way, when water flows into the water inlet and outlet cavity through the water inlet end 61 and is removed from the water outlet end 63, the water wheel can be driven to rotate. A reduction gear system is provided in the transmission component cavity 642, and the input end of the reduction gear system is connected to the rotating shaft of the water wheel. In this way, the reduction gear system can be driven to rotate by the water flow, and by designing a certain transmission ratio, the flow rate of the water flow can be measured like a water meter.

[0056] The output end of the reduction gear system is connected to a second transmission shaft 6132 which is jointly regulated by the water pressure in the pressure chamber 641 and an external spring, and a cam is arranged on the second transmission shaft 6132; a ratchet 654 is arranged on the rotating shaft of the water wheel, and a pawl 6123 which is adapted to the ratchet 654 is arranged in the transmission component chamber 642, and a cam is arranged on the rotating shaft of the pawl 6123 to abut against the cam on the second transmission shaft 6132; a first strong magnet 6124 is connected to the end of the pawl 6123, and a second strong magnet 6125 which is magnetically attracted to the first strong magnet 6124 is arranged in the transmission component chamber 642, and the second strong magnet 6125 is fixed on the second filling layer 610 through a magnet placement seat 6126.

[0057] Thus, in the present application, water flows through the water inlet and outlet cavity to drive the rotating shaft to rotate, and the rotation is reflected to the second transmission shaft 6132 through the reduction gear system. When the second transmission shaft 6132 rotates a certain angle, the second transmission shaft 6132 is provided with a cam to drive the rotating shaft connected thereto to rotate, driving the pawl 6123 to buckle the ratchet 654 on the rotating shaft, thereby stopping the rotation of the water wheel, and after the water wheel stops rotating, it limits the water inlet end 61 and the water outlet end 63, thereby achieving the purpose of reducing the water output. At this time, the water pressure in the pressure chamber 641 is the largest, and the second transmission shaft 6132 is supported by this water pressure so that it cannot move, thereby maintaining the locking of the pawl 6123 to the ratchet 654. When the rotating shaft is locked, the semicircular groove is blocked at the water inlet end and the water outlet end, thereby completing the flow restriction of the water flow. The present application realizes mechanical flow limiting of a water flow valve by utilizing water pressure and magnetic force, so that in irrigation of plants on a slope, the system can realize automatic quantitative irrigation without powering each valve and without manual intervention.

[0058] In one embodiment, Figure 3As shown, the present application provides a specific water wheel structure, the water wheel includes a central rotating shaft 651, a connecting rod 652, a semicircular groove 653, a ratchet 654, and a first sprocket 656; wherein the central rotating shaft 651 is connected between the water inlet and outlet cavity and the transmission component cavity 642, a plurality of connecting rods 652 are connected and arranged on the top of the central rotating shaft 651, and a semicircular groove 653 is connected and arranged on the other end of the plurality of connecting rods 652, and the semicircular groove 653 faces the water inlet end 61 when rotating with the central rotating shaft 651; a first sprocket 656 and a ratchet 654 are arranged on the central rotating shaft 651 located in the transmission component cavity 642. In this way, the plurality of semicircular grooves 653 drive the central rotating shaft 651 to rotate with the impact of the water flow, thereby driving other components thereon to rotate. It should be noted that when the ratchet 654 is stuck, one of the semicircular grooves 653 is located at the water inlet end 61 and the other is located at the water outlet end 63, so that the water flow can be limited as much as possible.

[0059] In one embodiment, Figure 3 and Figure 8 As shown, in order to facilitate the reduction transmission and provide stability of each rotating shaft during rotation, the reduction gear system includes a first transmission shaft 67, a first transmission chain 68, and a speed gear set 69; a first filling layer 66 is arranged in the transmission component cavity 642, the first transmission shaft 67 is connected to the first filling layer 66, one end of the first transmission shaft 67 is provided with a sprocket, and the other end is connected with a gear, one end of the first transmission shaft 67 is transmission-connected with the first sprocket 656 through the first transmission chain 68, and the other end is meshed and connected with the speed gear set 69, and a sprocket is arranged on the rotating shaft of the last gear of the speed gear set 69. In this way, the rotating shafts and transmission shafts of each gear are arranged by the first filling layer 66 to avoid excessive suspension and improve strength.

[0062] In one embodiment, Figure 4 and Figure 5As shown, in order to facilitate the opening and closing of the pawl, a cavity is provided between the first filling layer 66 and the third filling layer 614, in which a pawl cam 6121 is provided, and the pawl 6123 is connected to the pawl cam 6121, and the pawl cam 6121 abuts against the third cam 6134 to drive the pawl 6123 to move and clamp the ratchet 654; the third cam 6134 is connected to the second transmission shaft 6132, and the rotating shaft of the pawl cam 6121 passes through the third filling layer 614 and is connected to the first cam 6122.

[0063] In one embodiment, Figure 3 As shown, a slide plate 6137 is slidably provided in the pressure chamber 641, and one side of the slide plate 6137 is connected to form a pressure expansion device auxiliary spring to adjust the second transmission shaft 6132 by using water pressure. In order to facilitate the use of water pressure to form a pressure expansion device auxiliary spring to adjust the second transmission shaft 6132, the present application is provided with a slide shaft 6135, which is slidably provided on the cavity wall between the pressure chamber 641 and the transmission component cavity 642, and one end of the slide shaft 6135 is connected to a rotating shaft seat, and the second transmission shaft 6132 is transferred to the rotating shaft seat, and a second spring 6136 is provided between the rotating shaft seat and the cavity wall. In this way, when the pressure in the pressure chamber 641 is relatively high, the slide plate 6137 is pressed to move to one side and maintain, so that the pressure is maintained by the water pressure, and when the water pressure decreases, the slide plate 6137 is pulled back by the second spring 6136 to reset.

[0064] In one embodiment, Figure 6 , Figure 7 and Figure 8 As shown, since the second transmission shaft 6132 is movable and adjustable, the transmission reduction gear set is not used, so the middle and lower part of the second transmission shaft 6132 is connected with a second cam 6133, and the second cam 6133 abuts against the first cam 6122; the bottom of the second transmission shaft 6132 is connected with a fourth sprocket 6131, and the fourth sprocket 6131 is connected with the sprocket on the speed change gear set 69 through a transmission chain. A tensioning sprocket 611 is provided on the transmission chain of the fourth sprocket 6131 to adjust the tightness, and the speed change gear set 69 is connected through the transmission chain, and the transmission chain caused by the adjustment of the second transmission shaft 6132 is adjusted by the tensioning sprocket 611, so as to maintain the transmission.

[0065] In one embodiment, Figure 3 and Figure 8 As shown, in order to facilitate the tensioning and adjustment of the tensioning wheel, the tensioning sprocket 611 is connected to the sprocket seat 6111, the sprocket seat 6111 is connected to the sliding shaft 6113, the sliding shaft 6113 is slidably connected to the cavity wall of the second filling layer 610, and a first spring 6112 is arranged between the cavity wall of the second filling layer 610 and the sprocket seat 6111.

[0066] Some of the workflows for this application are as follows:

[0067] The water pump 4 provides a constant water pressure, and the water flow or water pressure enters the flow limiting water valve 6 from the water inlet end 61. While filling, the water flow or water pressure provides a constant pressure for the pressure chamber 641, pressing the slide plate 6137 to overcome the elastic force of the second spring 6136 and remain in the extended state. As water flows out from the sprinkler nozzle, water continuously flows in from the water inlet end 61 and flows out from the water outlet end 63. During the flow of water, the central shaft 651 is driven to rotate. The rotation of the central shaft 651 is transmitted to the speed change gear set 69 through the first transmission chain 68 and the first transmission shaft 67 for deceleration, and then the speed change gear set 69 is finally transmitted to the second transmission shaft 6132 through the transmission chain to drive it to rotate, and the second transmission shaft 6132 drives the third cam 6134 thereon to rotate. Due to the use of the speed change gear set 69 or the variable gear set, the central shaft 651 needs to rotate multiple times before it can be transmitted to the second transmission shaft 6132. Therefore, it can be achieved that after a certain amount of water flows out, the third cam 6134 drives the ratchet cam 6121 to rotate, thereby driving the ratchet 6123 to rotate, buckling the ratchet 654 on the central shaft 651, thereby locking the central shaft 651 from rotating. Prior to this, the pawl 6123 is magnetically attracted to the first strong magnet 6124 and the second strong magnet 6125 to open the ratchet 654. When the first transmission shaft 67 is locked, the semicircular groove 653 is blocked at the water inlet 61 and the water outlet 63, thereby completing the flow restriction of the water flow.

[0068] When irrigation is completed, the water pump 4 stops, the pressure in the pressure chamber 641 decreases, the second spring 6136 pulls back the second transmission shaft 6132, the ratchet cam 6121 is not held, and is sucked back by the second strong magnet 6125, thereby opening the ratchet 654, and the remaining water in the pipeline continues to flow from the irrigation nozzle, continuing to drive the central shaft 651 to rotate, so that the third cam 6134 leaves the ratchet cam 6121 until all water flows out and stops. In this process, in order to prevent the second spring 6136 from being unable to retract normally, while the second spring 6136 is sucked back by the second strong magnet 6125, the first cam 6122 on its shaft rotates to push the second cam 6133 to assist the sliding shaft 6135 to retract.
