Description

Technical Field

[0001] This invention relates to the technical field of irrigation water activation equipment, specifically to an irrigation water activation device with controllable field strength, and also to a magnetizer for irrigation water activation. Background Technology

[0002] By controlling irrigation water to flow vertically through a magnetic field at a certain velocity, large water molecules are broken down into smaller water molecules under the influence of the magnetic field. The activity of water molecules is significantly enhanced, and the physicochemical properties of water, such as surface tension, solubility, viscosity, ionization, and pH, are significantly improved. This achieves the purpose of water quality activation, while also increasing water activity, enhancing water carrying capacity, improving water absorption by crop roots, stimulating crop growth and yield, and improving crop quality.

[0003] Common activation treatments include magnetization, de-electrolysis, oxygenation, ionization, and high-voltage electric field treatment. In contrast, magnetization uses a permanent magnetic field to activate water molecules, requiring no external energy supply, offering long lifespan of permanent magnets, low cost, and simple manufacturing processes, leading to its widespread application. However, the more complex the structure, magnetic circuit, and magnetic field design of the permanent magnet, the higher the cost of the magnetizer. Furthermore, the development of magnetizers requires consideration not only of the water flow performance but also of the magnetic field strength and uniformity of its distribution.

[0004] Chinese patent application (application number 2019104306964) proposes a magnetization and ionization magnesiumation device for irrigation pipes in saline-alkali land and saltwater. Its core magnetization part adopts a circumferential arrangement of rod-shaped magnets. Under this arrangement, the gaps between the magnets are non-uniform, which will generate a non-uniform magnetic field. When water flows through, the magnetization intensity varies greatly, resulting in poor magnetization effect.

[0005] Chinese patent application (application number 2021108198701) proposes an irrigation brackish water treatment device. Its magnet structure adopts a sector magnet and is equipped with a positioning column, pressure plate one, pressure plate two and fixing column to adjust the magnetic field uniformity of the sector magnet, which effectively improves the magnetization effect. However, the magnetic field strength adjustment range of this technology is small.

[0006] The applicant's previous research has shown that magnetic field strength has a significant impact on the transport time, infiltration rate, infiltration volume, and diffusion rate of activated water, and also has a considerable influence on crop growth indicators, yield, and quality, especially at different growth stages. Recent, more detailed studies have found that magnetization intensity, magnetization gradient, and number of magnetization cycles have a more significant impact on crop growth at different growth stages. However, to date, magnetization technologies and equipment capable of adjusting magnetization intensity, magnetization gradient, and number of magnetization cycles have not been reported, especially in applications in agricultural production. Summary of the Invention

[0007] The first objective of this invention is to provide an irrigation water activation device with controllable field strength, which facilitates rapid adjustment of magnetization intensity.

[0008] To achieve the first objective, the technical solution adopted by this invention is as follows: a controllable field strength irrigation water activation device, comprising a magnetic group unit, a water-blocking telescopic unit, a magnetic group gap adjustment linkage unit, and a sealing support unit. Multiple magnetic group units are arranged circumferentially at intervals within the sealing support unit. A gap is maintained between adjacent magnetic resistance units to allow water flow through and to magnetize and cut the water flow. Each magnetic group unit has a water-blocking blade at its inner end, and multiple water-blocking blades are staggered to form a central sealing structure. The water-blocking telescopic unit is connected between the outer ends of two adjacent magnetic group units and moves radially and expands with the magnetic group units, used to seal the gap in the non-magnetic resistance area. The magnetic group gap adjustment linkage unit is connected between the magnetic group units and the sealing support unit, used to adjust the radial movement position of the magnetic group units to adjust the gap between adjacent magnetic resistance units.

[0009] Furthermore, the aforementioned magnetic assembly unit includes a Hellbeck magnetic assembly and a sector-shaped magnetic base. The Hellbeck magnetic assemblies are symmetrically installed in two sets on both radial sides of the sector-shaped magnetic base. The outer end of the sector-shaped magnetic base is connected to the magnetic assembly gap adjustment linkage unit. Each Hellbeck magnetic assembly includes a first magnet and a second magnet. Multiple pairs of the first magnet and the second magnet are connected and locked onto the sector-shaped magnetic base in the Hellbeck sequence.

[0010] Furthermore, the aforementioned water-blocking telescopic unit includes a first water-blocking plate, a second water-blocking plate, and a third water-blocking plate. The third water-blocking plate is embedded in the first track grooves provided on both sides of the second water-blocking plate and maintains a sealed fit with the second water-blocking plate. The outer end of the first water-blocking plate is fixedly connected to the sealing bracket unit. The outer side of the first track grooves on both sides of the second water-blocking plate is embedded in the second track grooves provided on both sides of the first water-blocking plate and maintains a sealed fit with the first water-blocking plate. An adjusting nut is fixedly connected to the third water-blocking plate. The adjusting nut is connected to the magnetic group gap adjustment linkage unit through a water-blocking adjuster for adjusting the extension and retraction of the water-blocking telescopic unit.

[0011] Furthermore, the aforementioned magnetic group gap adjustment linkage unit includes a magnetic group adjuster, positioning bolts, a bracket, and an axial gear ring. The bracket is fixedly connected to the sealing bracket unit. The bracket has a ring structure, with the same number of sliding wings as the magnetic group unit arranged radially on its inner side. Two positioning bolts are fixed on the sliding wings. The positioning bolts move through two radial positioning strip-shaped through holes arranged on the fan-shaped magnetic base. The magnetic group adjuster is radially rotatably connected to the sealing bracket unit, and its inner end is spirally connected to the outer end of the fan-shaped magnetic base. The axial gear ring is rotatably connected to the bracket. The magnetic group adjuster is provided with a first drive gear that meshes with the end face teeth of the axial gear ring. The water-blocking adjuster is provided with a second drive gear that meshes with the end face teeth of the axial gear ring. Rotating the magnetic group adjuster drives the fan-shaped magnetic base to move radially, and the rotation of the first drive gear drives the axial gear ring to rotate. After the axial gear ring rotates, it drives the remaining first drive gear and second drive gear to rotate, thereby driving the remaining fan-shaped magnetic bases to move radially and all water-blocking telescopic units to extend and retract.

[0012] Furthermore, the aforementioned magnetic assembly adjuster has a sealing post at its outer end and a first rectangular threaded portion at its inner end. The sealing post has an internal hexagonal countersunk hole on its end face. The first drive gear is fixedly connected to the magnetic assembly adjuster and closely attached to the inner end of the sealing post. The first rectangular threaded portion is spirally connected to the radial rectangular adjusting threaded hole at the middle of the outer end of the fan-shaped magnetic base. The sealing post is sealed with the radial stepped through hole passing through the sealing support unit and is sealed with a stepped sealing ring.

[0013] Furthermore, the aforementioned axial toothed ring and the bracket are connected by ball rolling. The side of the axial toothed ring that contacts the ball is provided with an arc-shaped slide rail for receiving the ball, and the side of the bracket that contacts the ball is provided with an arc-shaped slide channel for receiving the ball.

[0014] Furthermore, the outer end of the aforementioned water-blocking regulator is fixedly connected to a second drive gear, and the inner end is provided with a second rectangular threaded portion, which is screwed to the adjusting nut.

[0015] Furthermore, the aforementioned sealing bracket unit includes a rear transparent cover and a front transparent cover, which are fixed together by fastening bolts. A radial through hole for accommodating a sealing post is provided between the rear transparent cover and the front transparent cover. A sealing ring is provided between the through hole and the sealing post. A sealing gasket is provided at the contact point between the rear transparent cover and the front transparent cover for sealing. The bracket is fixedly connected between the rear transparent cover and the front transparent cover.

[0016] The second objective of this invention is to provide a magnetizer for activating irrigation water, which facilitates the adjustment of the magnetization gradient and the number of magnetization cycles.

[0017] Regarding the second objective of the invention, the technical solution adopted by the present invention is as follows: a magnetizer for activating irrigation water, comprising the aforementioned irrigation water activation device and steel pipes, wherein two steel pipes are welded to the outer edge of the inlet and outlet ends of the irrigation water activation device, and a reducing pipe with gradually decreasing diameter is provided at the other end of the two steel pipes, and a flange is provided at the end of the reducing pipe.

[0018] Furthermore, multiple irrigation water activation devices are used and connected in series on the steel pipe of the magnetizer.

[0019] The beneficial effects of this invention are as follows: Compared with the prior art, this invention proposes an irrigation water activation device with controllable field strength. It adopts multiple sets of magnetic units arranged circumferentially, and adjusts the size of the gap between adjacent magnetic units through a magnetic unit gap adjustment linkage unit to change the water flow gap, thereby adjusting the magnetic field spacing and field strength. The adjustment is convenient and quick, effectively solving the problem of difficult magnetic field strength adjustment in existing irrigation water magnetic field activation technologies.

[0020] The invention specifically designs elongated modified magnets to enhance the uniformity of the magnet's surface magnetism. Utilizing Hellbeck's principle, the magnets are combined into magnetic assemblies to increase the magnetic field strength of these assemblies. An innovative radial fan-shaped slide rail mechanism is designed to drive the movement of the magnetic assemblies, altering the water flow gap and thus adjusting the magnetic field spacing and strength. This device can be installed within a single-stage magnetization device or combined within a multi-stage magnetization device to achieve gradient and multiple magnetization effects. The innovative technology proposed in this invention solves the problem of difficulty in adjusting the magnetic field strength, gradient magnetization, and number of magnetization cycles in existing irrigation water magnetic field activation technologies.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1: As Figure 1-19 As shown, an irrigation water activation device with controllable field strength includes a magnetic group unit 1, a water-blocking telescopic unit 2, a magnetic group gap adjustment linkage unit 3, and a sealing support unit 4. Multiple magnetic group units 1 are arranged circumferentially in the inner cavity of the sealing support unit 4. A gap 6 (0-5° (preferably parallel, i.e., 0°)) is maintained between adjacent magnetic resistance units 1 to allow water flow to pass through and to magnetize and cut the water flow. Each magnetic group unit 1 has a water-blocking blade 10206 at its inner end. Multiple water-blocking blades 10206 are stacked alternately to form a central sealing structure. The water-blocking telescopic unit 2 is connected between the outer ends of two adjacent magnetic group units 1 and moves radially and expands with the magnetic group unit 1, used to seal the gap in the non-magnetic resistance area. The magnetic group gap adjustment linkage unit 3 is connected between the magnetic group unit 1 and the sealing support unit 4, used to adjust the radial movement position of the magnetic group unit 1 to adjust the gap 6 between adjacent magnetic resistance units 1.

[0025] The aforementioned magnetic unit 1 includes a Hellbeck magnetic assembly 101 and a sector-shaped magnetic base 102. The Hellbeck magnetic assembly 101 employs two sets (i.e., as shown in the figure). Figure 4The first Heilbeck magnetic group 101-1 and the second Heilbeck magnetic group 101-2 are symmetrically installed on the radial sides of the sector-shaped magnetic base 102 at the first mounting station 10201 and the second mounting station 10202 (the first mounting station 10201 and the second mounting station 10202 are slot structures). During installation, it should be ensured that the strong magnetic end faces outward and the weak magnetic end faces inward, and that the magnetic pole directions of the two magnetic groups 101 at the first mounting station 10201 and the second mounting station 10202 are opposite (i.e., the magnetic pole directions of the first magnetic group 101-1 and the second magnetic group 101-2 are opposite, and the magnetic groups on adjacent sides of the two sector-shaped magnetic bases 102 remain parallel). The outer end of the sector-shaped magnetic base 102 is connected to the magnetic group gap adjustment linkage unit 3. Each Heilbeck magnetic group 101 contains... The system includes a first magnet 10101 and a second magnet 10102. Multiple pairs of the first magnet 10101 and the second magnet 10102 are connected and locked onto the sector-shaped magnetic base 102 in a Heilbeck sequence. The sector-shaped magnetic base 102 is radially symmetrically provided with a first radial positioning strip-shaped through hole 10203 and a second radial strip-shaped through hole 10204. A positioning bolt 104 passes through both the first radial positioning strip-shaped through hole 10203 and the second radial strip-shaped through hole 10204, and the positioning bolt 104 is connected to the sliding fin 30101 of the bracket 301. A serrated groove is provided in the direction of contact between the first magnet 10101 and the second magnet 10102 and the water flow, and a soft magnet 10103 is provided in the serrated groove to further improve the uniformity of the magnetic field distribution on the magnet surface.

[0026] Among them, such as Figure 1 and 7As shown in Figure -8, the water-blocking telescopic unit 2 includes a first water-blocking plate 201, a second water-blocking plate 202, and a third water-blocking plate 203. The third water-blocking plate 203 is embedded in the first track grooves provided on both sides of the second water-blocking plate 202 and maintains a sealed fit with the second water-blocking plate 202. The outer end of the first water-blocking plate 201 is fixedly connected to the sealing bracket unit 4 (i.e., the positioning groove 30103 on the bracket 301). The outer side of the first track grooves on both sides of the second water-blocking plate 202 is embedded in the second track grooves provided on both sides of the first water-blocking plate 201 and maintains a sealed fit with the first water-blocking plate 201. The third water-blocking plate 203 is fixedly connected to an adjusting nut 204. The adjusting nut 204 is connected to the magnetic group gap adjustment linkage unit 3 through the water-blocking adjuster 205 and is used to adjust the extension and retraction of the water-blocking telescopic unit 2. The water-blocking regulator 205 has a second drive gear 20502 fixedly connected to its outer end, and a second rectangular thread 20501 provided at its inner end. The second rectangular thread 20501 is screwed to the adjusting nut 204. The second drive gear 20502 meshes with the end face toothed ring 30301. When the end face toothed ring rotates, it drives the second drive gear to rotate, thereby driving the water-blocking telescopic unit to extend and retract. The end face toothed ring 30301 is provided with two limiting flanges 30303, which can limit the axial movement of the second drive gear 20502. The water-blocking unit can block the gap position that is not in a magnetic field.

[0027] Specifically, such as Figure 8 As shown, a limiting baffle 20101 is provided at one end of the first water-blocking plate 201 near the second water-blocking plate 202. A limiting protrusion 20201 is provided at one end of the second water-blocking plate 202 that extends into the second track groove of the first water-blocking plate 201. During sliding, the limiting baffle 201 prevents the limiting protrusion 202 from sliding out of the second track groove, thus preventing the second water-blocking plate from detaching. A limiting baffle 20202 is provided at one end of the second water-blocking plate 202 near the third water-blocking plate 203. The third water-blocking plate 203 extends into the second water-blocking plate 202. A limiting protrusion 20301 is set at one end of the second track groove. During the sliding process, the limiting baffle 2 prevents the limiting protrusion 2 from sliding out of the second track groove, thereby preventing the second water-blocking plate from detaching. The extension and retraction process is controlled as follows: when the adjusting nut moves towards the center (the center of the irrigation water activation device), it first drives the third water-blocking plate to move. When the limiting protrusion 2 of the third water-blocking plate is attached to the limiting baffle 2, the second water-blocking plate is moved towards the center. When it moves to the maximum position where the limiting baffle 1 is attached to the limiting protrusion 1, it generally will not reach this extreme position.

[0028] The magnetic group gap adjustment linkage unit 3 includes a magnetic group adjuster 103, a positioning bolt 104, a bracket 301, and an axial gear ring 303. The axial gear ring 303 has an end-face gear ring structure. The bracket 301 is fixedly connected to the sealing bracket unit 4. The bracket 301 has an annular structure, and the same number of sliding wings 30101 as the magnetic group units 2 are arranged radially on its inner side. The sliding wings 30101 have a fan-shaped plate structure. A positioning groove 30103 is provided between two adjacent sliding wings 30101. The positioning groove 30103 is used to fix the water-blocking telescopic unit 2. The telescopic sides of the water-blocking telescopic unit 2 are sealed and fitted to the sides of two adjacent magnetic group units. Two symmetrical sliding wings are provided on the sliding wings 30101. Bolt holes 30102 are connected to two positioning bolts 104. The positioning bolts 104 move through two radial positioning strip-shaped through holes provided on the sector-shaped magnetic base 102. The two radial positioning strip-shaped through holes are the first radial positioning strip-shaped through hole 10203 and the second radial positioning strip-shaped through hole 10204. The two positioning bolts cooperate with the two radial positioning strip-shaped through holes to restrict the magnetic assembly unit 1 to only slide radially. The sliding fins cooperate with the bolts to support the magnetic assembly unit. The magnetic assembly adjuster 103 is radially rotatably connected to the sealing bracket unit 4 near its outer end, and its inner end is spirally connected to the radial rectangular adjusting threaded hole 10205 provided on the outer end of the sector-shaped magnetic base 102. The rotating magnetic... The magnetic group adjuster 103 drives the radial movement of the magnetic group unit 1. The magnetic group adjuster 103 is mechanically connected to the radial rectangular adjusting threaded hole 10205 of the sector magnetic base 102 via a rectangular thread 10301, forming a threaded transmission mechanism. Compared to other thread types, the rectangular thread has higher torque transmission and self-locking capabilities. The axial gear ring 303 is rotatably connected to the bracket 301. The magnetic group adjuster 103 is equipped with a first drive gear 10302 that meshes with the end face teeth of the axial gear ring 303. The water-blocking adjuster 205 is equipped with a second drive gear 20502 that meshes with the end face teeth of the axial gear ring 303. Rotating the magnetic group adjuster 103 causes it to rotate, which, through a torque... The threaded drive causes the sector magnetic base 102 to move radially, and the rotation of the first drive gear 10302 drives the axial gear ring 303 to rotate. After the axial gear ring 303 rotates, it drives the remaining first drive gear 10302 and the second drive gear 20502 to rotate, thereby driving the remaining sector magnetic bases 102 to move radially and all water-blocking telescopic units 2 to extend and retract. The bracket 303 has multiple positioning grooves 30103 circumferentially arranged on the inner side. Each positioning groove 30103 is located between two adjacent sliding wings 30101 and is used to install the water-blocking telescopic unit 2. The gear 10302 of the magnetic group adjuster 103 and the end face gear ring 30301 of the axial gear ring 303 form an external gear mesh and transmit power.The sealing post 10303 of the magnetic group regulator 103 is externally connected to a sealing ring 404 to prevent water leakage inside the device. The end face toothed ring 30301 is provided with two limiting flanges 30303, which are two annular upward convex structures arranged around the end face toothed ring. They are used to axially limit the second drive gear 20502 and can also circumferentially limit the first drive gear 10302.

[0029] Specifically, the magnetic assembly adjuster 103 has a sealing post 10303 at its outer end and a first rectangular threaded portion 10301 at its inner end. The end face of the sealing post 10303 has an internal hexagonal countersunk hole 10304. The first drive gear 10302 is fixedly connected to the magnetic assembly adjuster 103 and closely abuts the inner end of the sealing post 10303. The first rectangular threaded portion 10301 is spirally connected to a radial rectangular adjusting threaded hole 10205 located in the middle of the outer end of the sector-shaped magnetic base 102. The end of the sealing post 10303 near the first drive gear 10302 has an annular limiting step 10305 smaller than its diameter. The sealing post 10303 connects with the radial step through hole passing through the sealing support unit 4 and is in contact with it. The stepped sealing ring 404 is used for sealing. The radial stepped through hole and the annular limiting step 10305 form the axial limit of the magnetic group adjuster, thereby realizing the rotation of the magnetic group adjuster. After rotation, the magnetic group unit is driven to move radially on the sliding fin by the rectangular thread at the inner end. The internal hexagonal countersunk hole is convenient to operate with an internal hexagonal wrench. The rectangular thread drive has a large driving force. The radial stepped through hole is formed by the first semi-circular sealing groove 40101 set in the rear through cover 401 and the second semi-circular sealing groove 40201 set in the front through cover 402. The sealing groove set in the semi-through cover structure is formed, which is convenient to install the integrated magnetic group adjuster or the first drive gear is detachably fixed to the magnetic group adjuster by the expansion tightening method.

[0030] Specifically, the aforementioned axial gear ring 303 and the bracket 301 are connected by rolling balls 302. The side of the axial gear ring 303 that contacts the balls 302 is provided with an arc-shaped slide rail 30302 to accommodate the balls 302. The axial gear ring 303 is provided with an end face gear ring 30101 on the side opposite to the arc-shaped slide rail 30302. The side of the bracket 301 that contacts the balls 302 is provided with an arc-shaped slide channel 30104 to accommodate the balls 302. The bracket 301, balls 302 and gear ring 303 constitute an axial thrust bearing transmission structure. The end face gear ring 30101 meshes with both the first drive gear and the second drive gear. The axial thrust bearing transmission structure of the balls rotates sensitively and quickly, and provides stable and reliable support. The axial gear ring 303 is axially positioned by multiple circumferentially distributed first drive gears and second drive gears.

[0031] The sealing bracket unit 4 includes a rear cover 401 and a front cover 402, which are fixed together by fastening bolts 403. A radial through hole for accommodating the sealing post 10303 is provided between the rear cover 401 and the front cover 402 (i.e., the radial through hole is formed by the mating of the first semi-circular sealing groove 40101 provided in the rear cover 401 and the second semi-circular sealing groove 40201 provided in the front cover 402). The radial through hole is connected to the sealing post 10303. A sealing ring 404 is provided between the rear cover 401 and the front cover 402. A sealing gasket 405 is provided at the joint between them. The sealing gasket 405 is provided with a bolt through hole 40501 through which the fastening bolt 403 passes. The bracket 301 is fixedly connected between the rear cover 401 and the front cover 402. After the rear cover 401 and the front cover 402 are fixedly connected to the bracket 301 as a whole, they provide support for the entire equipment. An inner convex ring is provided around the bottom of the rear cover 401 to support and fix the bracket.

[0032] The specific functions of each of the above modules are as follows: 1) Heilbeck magnetic group magnetic field enhancement function: The Heilbeck magnetic group 101 is composed of a first magnet 10101 and a second magnet 10102 in the Heilbeck sequence. A serrated groove is provided in the direction of contact between the first magnet 10101 and the second magnet 10102 and the water flow. A soft magnet 10103 is provided in the serrated groove to further improve the uniformity of the magnetic field distribution on the magnet surface. The first installation station 10201 and the second installation station 10202 for installing the Heilbeck magnetic group 101 are provided on both sides of the fan-shaped magnetic base 102. The magnetic poles of the two sets of Heilbeck magnetic groups (i.e., the first Heilbeck magnetic group 101-1 and the second Heilbeck magnetic group 101-2) are arranged oppositely to ensure that opposite magnetic groups generate magnetic fields of attraction between adjacent magnetic groups.

[0033] 2) Controllable magnetic field adjustment function: such as Figure 1 In this structure, one magnetic unit 1 can be arranged on each of the ten sliding wings 30101 around the circumference of the bracket 301, forming a total of ten magnetic units 1. The ten magnetic units 1 form a unified whole through the end face toothed ring 30301. When an Allen wrench is inserted into the Allen countersunk hole 10304 of any magnetic unit adjuster 103 and rotated counterclockwise, the ten magnetic units can be controlled to move away from the center of the bracket 301 along the first radial positioning strip through hole 10203 and the second radial strip through hole 10204 under the drive of the end face toothed ring 30301, thereby increasing the circumferential spacing between adjacent magnetic units 1 (e.g., ...). Figure 14 d1 becomes Figure 15 In the d2 section), the magnetic field strength decreases. Conversely, when rotated clockwise, the 10 magnetic unit 1 can be controlled to simultaneously move along the first radial positioning strip through hole 10203 and the second radial strip through hole 10204 closer to the center of the support 301, thereby reducing the circumferential spacing between adjacent magnetic unit 1 (e.g., ...). Figure 15 d2 becomes Figure 14 (d1) increases the magnetic field strength; the above process can achieve stepless adjustment of the magnetic field strength over a wide range from 0.1T to 1.2T.

[0034] 3) Water-blocking adjustment function: To ensure that all irrigation water flows are activated by passing through the magnetic field (gap 6), water-blocking blades 10206 are provided on the fan-shaped magnetic base 102. Ten sets of water-blocking blades are arranged in an axially staggered and overlapping manner to form a biomimetic petal structure. When the magnetic unit 1 moves radially, the overlapping area of ​​the fan-shaped magnetic base 102 is adjusted to prevent water from flowing through the central area. In addition, the water-blocking telescopic unit 2, driven by the toothed ring 30301, controls the first water-blocking plate 201, the second water-blocking plate 202, and the third water-blocking plate 203 to move synchronously with the fan-shaped magnetic base 102 to prevent water from flowing through the radially outer side of the fan-shaped magnetic base 102. The combination of water-blocking blades 10206 and water-blocking telescopic unit 2 restricts the water flow to only pass through the magnetic field area.

[0035] Example 2: As Figure 20 As shown, a magnetizer for activating irrigation water includes an irrigation water activation device A as described in Embodiment 1 and a steel pipe 501. Two steel pipes 501 are welded to the outer edges of the inlet and outlet ends of the irrigation water activation device A. The other ends of the two steel pipes 501 are provided with a reducing pipe 502 with a gradually decreasing diameter. A flange 503 is provided at the end of the reducing pipe 502.

[0036] Example 2 is a single-stage magnetizer structure, whose function is to magnetize irrigation water in a single cycle, and the intensity of each magnetization can be precisely set according to control needs.

[0037] Example 3: As Figure 21 As shown, a magnetizer for activating irrigation water includes two irrigation water activation devices A as described in Embodiment 1 and steel pipes 501. Two steel pipes 501 are welded to the outer edges of the inlet and outlet ends of the irrigation water activation device A to form an irrigation water activation device. The other ends of the two steel pipes 501 connected in series are provided with a reducing pipe 502 with a gradually decreasing diameter. A flange 503 is provided at the end of the reducing pipe 502.

[0038] Example 3 is a two-stage magnetizer structure, which functions to magnetize irrigation water twice. The strength of the two controllable field strength irrigation water activation devices A can be adjusted to be the same to achieve single-intensity two-stage magnetization, or the strength of the two controllable field strength irrigation water activation devices A can be adjusted to be different to achieve gradient magnetization.

[0039] Example 4: Figure 22As shown, a magnetizer for activating irrigation water includes three irrigation water activation devices A as described in Embodiment 1 and steel pipes 501. Two steel pipes 501 are welded to the outer edges of the inlet and outlet ends of the irrigation water activation device A to form an irrigation water activation device A. The three are connected in series, and at the other end of the two outermost steel pipes 501, a reducing pipe 502 with a gradually decreasing diameter is provided. A flange 503 is provided at the end of the reducing pipe 502.

[0040] Example 4 is a three-stage magnetizer structure, which functions to magnetize irrigation water three times. The intensity of the three-stage controllable field strength irrigation water activation device A can be adjusted to be the same according to control needs to achieve single-intensity three-stage magnetization. Alternatively, the intensity of the three-stage controllable field strength irrigation water activation device A can be adjusted to be different to achieve gradient magnetization. Furthermore, the intensity of the controllable field strength irrigation water activation device A can be combined to achieve multiple and gradient combination magnetization.

[0041] Example 5: Figure 23 As shown, a magnetizer for activating irrigation water includes five irrigation water activation devices A as described in Embodiment 1 and steel pipes 501. Each irrigation water activation device A has two steel pipes 501 welded to the outer edge of its inlet and outlet ends to form an irrigation water activation device A. The five are connected in series, and at the other end of the two outermost steel pipes 501, a reducing pipe 502 with a gradually decreasing diameter is provided. A flange 503 is provided at the end of the reducing pipe 502. Example 5 is a five-stage magnetizer structure, which functions to magnetize irrigation water five times. The intensity of the five-stage controllable field strength irrigation water activation device A can be adjusted to be the same to achieve single-intensity five-stage magnetization, or the intensity of the five-stage controllable field strength irrigation water activation device A can be adjusted to be different to achieve gradient magnetization. The intensity of the controllable field strength irrigation water activation device A can also be combined to achieve multiple and gradient combination magnetization.

[0042] Examples 3-5 demonstrate gradient magnetization and multiple magnetization adjustment functions: To achieve gradient magnetization, multiple controllable magnetic field devices can be installed inside the magnetizer. When the magnetic field strengths of the multiple controllable magnetic field devices are inconsistent, such as 0.1T, 0.3T, 0.5T, 0.8T, 1.0T, etc., gradient magnetization can be achieved. When the magnetic field strengths of the multiple controllable magnetic field devices are the same, such as 0.3T or 0.5T, multiple magnetization effects can be achieved. When multiple identical / dissimilar alternating field strengths are set, gradient magnetization and multiple magnetization of irrigation water can be achieved. Because water flow magnetization requires a certain flow rate and magnetization time, the spacing between adjacent controllable magnetic field devices should be set according to requirements.

[0043] In summary, the advantages of this invention are as follows: Through the above settings and operations, the present invention produces the following beneficial effects: 1) By using the Hellbeck principle and modified software to set up the Hellbeck magnetic array, the magnetic field uniformity of a single magnet can be enhanced, and the magnetic field strength and magnetic field distribution of the magnetic array can be increased. 2) Through the magnetic unit, the magnetic field strength can be steplessly adjusted within a wide range from 0.1T to 1.2T. It can be precisely and controllably adjusted according to the growth adjustment needs of different crops at different growth stages, making the equipment more flexible in use. 3) By deploying multiple controllable magnetic field devices and setting different field strengths, gradient magnetization of irrigation water can be achieved; 4) By deploying multiple controllable magnetic field devices with the same field strength, the irrigation water can be magnetized multiple times; 5) By deploying multiple controllable magnetic field devices and setting the same / different alternating field strengths, gradient magnetization and multiple magnetization of irrigation water can be achieved; 6) This controllable magnetic field device can also be used in other applications where the field strength is controllable, the gradient is adjustable, and the number of cycles is variable for other liquids and gases.
