DETAILED DESCRIPTION
[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below 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.
[0021] Reference Figure 1-12 , the present invention provides an induction detection controlled sprinkler irrigation system, comprising a sprinkler irrigation unit, and also comprising an execution unit for adjusting the sprinkler irrigation range of the sprinkler irrigation unit; And a control unit 3 that adjusts the execution unit according to the trajectory of personnel in the sprinkler irrigation area. The control unit controls the execution unit to adjust the sprinkler irrigation range of the sprinkler irrigation unit so that the sprinkler irrigation unit road and personnel are located outside the sprinkler irrigation range, thereby preventing the sprinkler irrigation system from affecting the environment outside the sprinkler irrigation area without affecting the sprinkler irrigation effect.
[0022] The sprinkler unit includes a rocker arm sprinkler 1 and a sprinkler pipe 7. The execution unit includes a baffle 2 for adjusting the sprinkler distance of the rocker arm sprinkler 1. In actual use, during the spraying process of the rocker arm sprinkler 1, the spraying coverage of the water flow is as follows: Fig.12 As shown, the sprayed water is spread out approximately evenly to the surrounding area with the nozzle as the center of the circle, and the baffle 2 is used to block the water flow sprayed by the rocker arm nozzle 1 from the top downward. The more the baffle is blocked, the closer the spray distance of the sprayed water flow is, and the smaller the coverage area is; The control unit 3 includes a detection radar 310 for detecting the trajectory of people in the sprinkler irrigation area and an adjustment mechanism for driving the baffle 2 according to the trajectory of the people. The detection radar 310 can be a human trajectory radar, such as a millimeter wave radar, or other detection means can also be used, such as a human recognition camera.
[0023] The movement trajectory of the detected person is detected, and the position of the detected person in the detection area is tracked, and the signal is sent to the controller 309, which obtains the orientation of the detected person, such as east, west, south, etc., and then calculates the distance between the detected person and the rocker arm sprinkler 1, and then adjusts the position of the baffle 2 through the adjustment mechanism, so that the baffle 2 blocks the sprinkler range of the rocker arm sprinkler 1 at this position, thereby avoiding spraying the person at this position.
[0024] The adjustment mechanism includes a magnetic block 301, an electromagnet 302, a support rod 303, a spring 304, and a rotating shaft 305; The lower part of the magnetic block 301 is fixedly connected to the rotating shaft 305, wherein the magnetic block 301 includes a shell 307 of non-magnetic material (such as a plastic shell 307), and a permanent magnet 308, the permanent magnet 308 is embedded in the shell 307, and the rotating shaft 305 and the shell 307 are fixedly connected by a connecting rod 306; One end of the support rod 303 is fixedly connected to the baffle 2, and the other end is hinged to the rotating shaft 305, so that the baffle 2 can rotate around the rotating shaft 305 in the up and down direction through the support rod 303, approaching or moving away from the nozzle 103; The two ends of the spring 304 are respectively connected to the magnetic block 301 and the support rod 303 to provide tension for the support rod 303 and the baffle 2; The electromagnet 302 is fixedly mounted on the support rod 303, and the magnetic block 301 corresponds to the magnetic pole of the electromagnet 302. Specifically, the permanent magnet 308 in the magnetic block 301 and the iron core in the electromagnet 302 are both cylinders, which is convenient for forming a strong magnetic force at the end of the cylinder, wherein the magnetic poles of the permanent magnet 308 and the electromagnet 302 that are close to each other are opposite, and because the magnetic force of the electromagnet 302 is mainly positively correlated with the current, the repulsive force between the electromagnet 302 and the permanent magnet 308 can be changed by adjusting the current.
[0025] In the present application, the support rod 303 is hinged with the rotating shaft 305, the spring 304 and the electromagnet 302 are used to adjust the rotation angle of the support rod 303 and the baffle 2, and the spring 304, the electromagnet 302, the rotating shaft 305, and the support rod 303 can form a labor-saving lever (such as Figure 6-9 As shown), it can actually form a laborious lever (not shown in the figure), or other structural angle adjustment methods.
[0026] The electromagnet 302 in the present application can also be replaced by other structures, such as a micro electric cylinder, a micro electric push rod, etc. When using a micro electric cylinder or a micro electric push rod, the two ends of the micro electric cylinder or the micro electric push rod are hinged to the support rod 303 and the outer shell 307 respectively.
[0027] There are multiple baffles 2, and the multiple baffles 2 are radially distributed, and the multiple baffles 2 form a circular structure; The magnetic block 301 is fixedly connected to the rotating shaft 305 via a connecting rod 306; One side of the magnetic block 301 is fixedly connected with a fixing frame 6, which can be inserted into the nearby ground, or a clamp can be installed at one end of the fixing frame 6 away from the rocker arm sprinkler head 1, and the fixing frame 6 is fixedly installed on the sprinkler water pipe 7 through the clamp.
[0028] In this embodiment, the position of the baffle 2 is stationary in the horizontal direction relative to the rocker arm sprinkler 1, and only rotates to a certain extent in the vertical direction. Therefore, the baffle 2 in this application is also stationary in the horizontal direction relative to the ground and the road. For the situation where some roads pass through the sprinkler area, one or more baffles 2 on the side adjacent to the road can be adjusted according to the position of the road, so that the baffle 2 blocks the water flow sprayed by the rocker arm sprinkler 1 from this position to prevent the water flow from being sprayed onto the road.
[0029] When a person approaches, the baffle 2 closest to the person is adjusted according to the person's activity trajectory so that the baffle 2 can block the water flow. As the person moves, the baffles 2 at different positions are adjusted to block the water flow and prevent it from spraying on the person.
[0030] The system further comprises a power supply unit 4 for supplying power to the control unit 3. By supplying power independently by the power supply unit 4, the system can operate independently, thus saving electric energy. Specifically, the power supply unit includes a solar panel 401, a battery 402, and of course, an inverter, a controller, etc., to improve the utilization rate of green energy.
[0031] The system also includes a lighting unit 5 installed beside the road in the sprinkler irrigation area. Considering factors such as water conservation, scientific irrigation, and reducing traffic impact, green belts are often irrigated at night. As for the technical problem to be solved by this application, it is more likely for pedestrians and cyclists to have unclear vision and road conditions at night, and they may even not see the sprinkler irrigation area. In this regard, the lighting unit 5 is used to provide sufficient light to the roads in the sprinkler irrigation area. Its main function is to prevent pedestrians and cyclists from stepping on puddles and slipping due to slippery roads.
[0032] The lighting unit 5 includes a street lamp 501 beside the road in the sprinkler irrigation area. The street lamp 501 is used to provide lighting. Firstly, it is more in line with the use environment of the location of the urban road green belt, and secondly, it can provide sufficient lighting; The detection radar 310 and the solar panel 401 are installed on the lamp pole of the street lamp 501 to reduce the obstruction of the detection radar 310 and the solar panel 401 and ensure the detection range of the detection radar 310 and the solar panel 401 to receive as much light as possible.
[0033] It should be noted that, in the present embodiment, the control accuracy of the baffle 2 does not need to be particularly accurate. For example, the baffle 2 in the present application is a fan ring structure with a central angle of 45 degrees, and there are a total of 8 baffles 2. In fact, the number of baffles 2 can be more or less. However, no matter how many baffles 2 there are, when controlling the baffle 2 to block the water flow sprayed from the nozzle 103, it is sufficient to control the water flow spray distance to be less than the distance from the personnel or the road to the rocker arm nozzle 1. Specifically, for example, if the distance between the personnel and the rocker arm nozzle 1 is 5 meters, then the baffle 2 is controlled to block the spray distance of the water flow dispensed by the nozzle 103 to be 4.5 meters, 3 meters, or 2 meters, or 1 meter, without the need to control the accuracy to be infinitely close to 5 meters.
[0034] As for the size of the "irrigation blind area" formed by the baffle 2 blocking the water flow, it is only necessary to ensure that the irrigation blind area can completely cover the road or personnel, without controlling the edge of the irrigation blind area to be infinitely close to the road or personnel. For example, in addition to preventing the water flow from spraying under the feet of people, the irrigation blind area must also ensure that the water flow ejected from both sides of the baffle 2 maintains at least a certain distance from the front and back of the people, such as a range of 1 meter.
[0035] If the baffle 2 uses a fan ring structure or a fan-shaped structure with a smaller central angle, or other slender structures, such as an elongated rectangle, a ring, etc., several adjacent baffles 2 can be adjusted at the same time to cooperate with each other to form a sufficient width to block the water flow and prevent the water flow from spraying onto people or roads.
[0036] The distances between the personnel, roads and the rocker arm sprinkler 1 mentioned in this application are all straight-line lengths from the personnel, roads to the rocker arm sprinkler 1 measured from the ground.
[0037] Example 2 Reference Figure 8-9 , the present invention is an induction detection controlled sprinkler irrigation system, the difference between this embodiment and embodiment 1 is that there is one baffle 2, and one baffle 2 is installed just above the nozzle 103; The rocker arm spray head 1 comprises a nozzle 103 and a spring seat 104, and a stainless steel spring of the rocker arm spray head 1 is installed inside the spring seat 104; The magnetic block 301 and the rotating shaft 305 are fixedly mounted on the spring seat 104 via a connecting rod 306 .
[0038] In this embodiment, the baffle 2 can rotate synchronously with the rotation of the rocker arm nozzle 1, and the baffle 2 and the nozzle 103 maintain the same orientation in the horizontal direction, and the baffle 2 and the ground move relative to each other.
[0039] In the process of keeping the baffle 2 and the nozzle 103 synchronized, when the nozzle 103 rotates to the road area, the control unit 3 adjusts the current of the electromagnet 302 according to the distance between the road and the rocker arm nozzle 1, changes the magnetic force of the electromagnet 302, and further adjusts the height of the baffle 2 to block the sprayed water flow.
[0040] When a person enters the sprinkler area, the control unit 3 detects the person's position. If the person does not appear in the spraying direction of the nozzle 103, there is no need to block the nozzle 103. If the person appears in the spraying direction of the nozzle 103, the pitch rotation angle of the baffle 2 is adjusted according to the relative position and distance between the person and the rocker arm sprinkler 1, so that the person is outside the spraying range of the rocker arm sprinkler 1.
[0041] The rocker arm sprinkler 1 also includes a sealing connection part 101 connected to the sprinkler water pipe 7 and a water spraying mechanism rotatably connected to the sealing connection part 101. The sealing connection part 101 is mainly a threaded interface part of the rocker arm sprinkler 1. The rocker arm sprinkler 1 is installed on the sprinkler water pipe 7 through the sealing connection part 101. If there is an angle limit ring, the angle limit ring is installed on the sealing connection part 101. The water spraying mechanism mainly includes a nozzle 103, a spring seat 104, and the stainless steel spring, swing arm, reversal control ring and other mechanisms of the rocker arm sprinkler 1 itself.
[0042] The water spray mechanism and the sealing connection part 101 are rotationally connected through a slip ring mechanism, and an electrical connection is formed between the electromagnet 302 and the slip ring mechanism and the controller 309 and the power supply unit 4 outside the control unit 3 to ensure that the electromagnet 302 can be normally energized during the rotation process. The controller 309 stores algorithms for human body recognition, pedestrian recognition, cyclist recognition, and coordinate orientation, which are existing technologies and will not be repeated here.
[0043] Specifically, the slip ring mechanism includes an inner rotating cylinder 105 mounted on the top of the sealing connection part 101 and an outer rotating cylinder 102 mounted on the bottom of the water spraying mechanism. The inner rotating cylinder 105 is fixedly mounted on the surface of the water pipe in the sealing connection part 101, and the outer rotating cylinder 102 is fixedly mounted on the surface of the water pipe in the water spraying mechanism. The outer rotating cylinder 102 is mounted on the surface of the inner rotating cylinder 105.
[0044] An inner electric slip ring 106 is embedded and fixed on the outer circumferential surface of the sealing connection part 101 , and an outer electric slip ring 107 slidably connected to the inner electric slip ring 106 is embedded on the inner circumferential surface of the outer drum 102 . The outer electric slip ring 107 is connected to external equipment.
[0045] Sealing rubber rings are installed at the gaps between the inner rotating drum 105 and the outer rotating drum 102 and the external environment to maintain the sealing effect of the inner rotating drum 105 and the outer rotating drum 102 during the rotation process and prevent water from contacting the inner electric slip ring 106 and the outer electric slip ring 107.
[0046] Working principle: When in use, the system is laid in a green belt or farmland. According to the actual situation, the road orientation information is input into the controller 309. When the nozzle 103 rotates to the direction of the road, the controller 309 controls the electromagnet 302 to push the baffle 2 to block the water flow sprayed from the nozzle 103 to prevent the water flow from spraying onto the road. When the detection radar 310 detects that a person has entered the sprinkler irrigation area, based on the person's position and activity trajectory (or static position) in the sprinkler irrigation area, when the nozzle 103 rotates to face the person, the baffle 2 in the same direction as the nozzle 103 is controlled to block the sprayed water flow to avoid spraying the person.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
