Description

Technical Field

[0001] The present invention relates to the technical field of desert irrigation, in particular to an irrigation device for desert areas. Background Art

[0002] Desertified land has poor soil and an extreme lack of fresh water. Plant seeds cannot attach and grow in quicksand. In addition, the plant growth cycle is very long and the survival rate is low, which leads to slow development of plant sand control. Photovoltaic power generation system refers to a power generation system that uses the photovoltaic effect of photovoltaic cells to directly convert solar radiation energy into electrical energy. It comes from inexhaustible solar energy and is a clean, safe and renewable energy. Therefore, combining photovoltaic power generation with desert control can achieve a win-win situation of ecological restoration and clean energy development through photovoltaic technology.

[0003] Desert areas have large spaces, little rainfall, and long sunshine hours, making them extremely suitable for photovoltaic power generation systems. They are also helpful for sand control and vegetation irrigation. Desert areas are generally far away from urban areas and have difficulty in obtaining electricity. Therefore, the method of utilizing solar energy resources to convert solar energy into mechanical energy and then drive the irrigation system is of great significance to agricultural development and desert control in desert areas. However, in desert areas, strong winds can cause the loss of sprinkler water, making it impossible for sprinkler water to accurately fall on the target area.

[0028] Beneficial effects:

[0029] 1. The present invention can control the internal flow of the annular shield by arranging an auxiliary mechanism for adjusting the nozzle outlet flow in the annular shield. In this way, in the case of strong winds, the opening is reduced, making the sprinkler irrigation more concentrated, thereby reducing the impact of wind on irrigation.

[0030] 2. The auxiliary mechanism of the present invention drives the annular member to rotate through the driving member, so that the offset member is offset to block the nozzle outlet, thereby adjusting the flow rate. The force transmission method and structure are simple and easy to implement.

[0031] 3. The sliding plate of the offset member of the present invention realizes its own movement along with the rotation of the annular member, thereby shielding the nozzle outlet. The structure is compact and the mechanism linkage is simple and reliable.

[0032] 4. The present invention also provides an adjustment mechanism for extending the protection height, which further enhances the windproof effect of the annular shield when in use.

At this time, the annular bar drives the interference part on the auxiliary block to rotate at the same time. When it rotates, the interference part contacts the wedge-shaped part, thereby squeezing the movable plate, causing the movable plate to move in the vertical direction, and at the same time the stretching spring is deformed. When the movable plate moves downward, it fills the gap after the adjustment plate rotates around the shaft seat I, further avoiding the influence of wind on irrigation.

DETAILED DESCRIPTION

[0047] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0048] Example 1

[0049] The present invention provides an irrigation device for desert areas, comprising a support body 100 , a photovoltaic panel 101 , a mounting frame 102 , an irrigation pipe 103 , a nozzle 105 , an annular shield 106 and an auxiliary mechanism 200 .

[0050] like Figure 1 、 Figure 2 As shown, a photovoltaic panel 101 is mounted on the upper end surface of a support body 100, and a mounting frame 102 is mounted on one side of the support body 100. An irrigation pipe 103 is mounted on the mounting frame 102, and multiple groups of nozzles 105 are mounted on the irrigation pipe 103. The nozzles 105 are mounted on the irrigation pipe 103 through nozzle seats 104. An annular shield 106 is mounted at the bottom end of the nozzles 105, and an auxiliary mechanism 200 for adjusting the outlet flow of the nozzles 105 is installed within the annular shield 106.

[0051] In this embodiment, an opening 107 is provided in the middle of the annular shield 106, and the opening 107 is connected to the outlet of the nozzle 105, that is, the nozzle 105 is located in the opening 107. In other words, the auxiliary mechanism 200 directly adjusts the outlet flow of the opening 107.

[0052] Photovoltaic sand control is an innovative model that combines photovoltaic power generation with desert control. It mainly achieves a win-win situation of ecological restoration and clean energy development through photovoltaic technology. The laying of photovoltaic panels 101 can effectively reduce surface wind speed and wind erosion, thereby stabilizing sand and preventing sand dunes from moving. The shading effect of photovoltaic panels 101 can reduce surface water evaporation. At the same time, photovoltaic panels 101 can regulate the thermal balance in desert areas, weaken the power of sandstorms and sand flows, and their rain collection function can also promote plant growth.

[0053] "Photovoltaic + Sand Control" model: Drought-resistant plants such as sago, wormwood, and alfalfa are planted under and between photovoltaic panels 101, which can not only prevent wind and sand, but also bring economic benefits. The space under and between photovoltaic panels 101 is used for planting and breeding, and water-saving agriculture is developed to form a comprehensive model of ground power generation, ground planting, and breeding between panels. In addition, ecological tourism is developed around the photovoltaic power station, combined with the construction of protective forest belts and industrial parks to achieve a combination of ecological and economic benefits.

[0054] Photovoltaic sand control can significantly increase vegetation coverage, increase soil moisture, and reduce the frequency of sandstorms. For example, after the photovoltaic power station is built, the vegetation coverage can reach more than 80%, which is 40% higher than outside the park, and the fresh grass yield is 4 times that outside the park. At the same time, the photovoltaic sand control project can generate a large amount of green electricity, while driving the development of related industries and creating employment opportunities. Therefore, photovoltaic sand control has brought significant economic benefits to the local community and promoted the development of rural revitalization and eco-tourism.

[0055] The "photovoltaic + agriculture" model converts the light energy in sunlight into electrical energy through photovoltaic panels 101. When sunlight shines on photovoltaic panels 101, photons are absorbed and excite electrons, thereby generating direct current. The generated direct current is transmitted to the inverter through a cable. The inverter converts the direct current into alternating current to meet the power demand of the water pump. The converted electrical energy drives the water pump to work. The water pump draws water from groundwater, rivers or lakes and transports the water to the irrigation pipe 103 through a water pipeline. At the same time, the power, flow rate and head of the water pump need to be matched according to the irrigation needs, and different irrigation methods can be selected according to actual needs, such as sprinkler irrigation and drip irrigation.

[0056] Desert areas are large, with little rainfall and long sunshine hours, making them extremely suitable for photovoltaic power generation systems. They are also helpful for sand control and vegetation irrigation. Desert areas are generally far away from urban areas. However, strong winds in desert areas can lead to the loss of sprinkler water. The main reason is that water droplets are blown away in the air by the wind and cannot accurately fall on the target area.

[0057] The prior art provides a shield at the bottom of the sprinkler head 105 to block the wind, thereby reducing the impact of wind on irrigation. The present invention further improves the structure of the shield by providing an auxiliary mechanism 200 in the annular shield 106. The auxiliary mechanism 200 changes the size of the opening 107 in the middle of the annular shield 106, thereby controlling the internal flow of the annular shield 106. In this way, in the case of strong winds, the opening 107 is reduced. According to the Bernoulli principle, the irrigation is more concentrated, thereby reducing the impact of wind on irrigation.

[0058] Specifically, the auxiliary mechanism 200 includes a driving member 201, an annular member 202 and an offset member 203; the driving member 201 is arranged on the upper end surface of the annular shield 106, the annular member 202 is mounted on the outside of the annular shield 106, and the offset member 203 is provided inside the annular member 202, and the offset member 203 is located inside the annular shield 106 and at the outlet of the nozzle 105; the driving member 201 drives the annular member 202 to rotate, so that the offset member 203 adjusts the outlet flow of the nozzle 105.

[0059] like Figure 3 As shown, the driving member 201 includes a fixing frame 201a fixedly connected to the upper end surface of the annular shield 106, a motor 201b and a gear 201c. The upper end of the fixing frame 201a is detachably mounted with the motor 201b, and the rotor shaft end of the motor 201b passes through one end of the fixing frame 201a and is connected to the gear 201c.

[0060] The upper end of the annular member 202 is an annular plate 202b, and the inner wall of the annular plate 202b is fixedly connected to a ring gear 202c, which is engaged with the gear 201c.

[0061] The fixing frame 201a has a concave structure to ensure the stability of the device during use. The motor 201b is installed on the fixing frame 201a by bolts. The output shaft end of the motor 201b is keyed to a gear 201c. The gear 201c engages with the gear ring 202c on the inner wall of the annular plate 202b, thereby driving the annular plate 202b on the inner ring to rotate. The rotation direction and angle of the rotor shaft end of the motor 201b are adjusted by an external controller. When the wind speed exceeds level 4, the external controller sends a command to adjust the motor 201b to operate, so that the gear 201c on the rotor shaft end of the motor 201b rotates. Since the gear 201c engages with the gear ring 202c, the annular plate 202b outside the gear ring 202c is driven to rotate.

[0062] A protective space 202d is formed within the annular shield 106. A symmetrical annular hole 202a is defined on the upper end surface of the annular shield 106. A connecting block 202e is fixedly connected to the bottom end of the annular plate 202b. The connecting block 202e slidably engages with the annular hole 202a. A circular strip 202f is provided at one end of the connecting block 202e, extending through the annular hole 202a on the upper end surface of the annular shield 106. A circular plate 202h is fixedly connected between the multiple groups of connecting plates 202g. A hollow hole 202i is defined in the middle of the circular plate 202h, which is correspondingly connected to the opening 107.

[0063] The protective space 202d formed in the annular shield 106 blocks the wind, thereby reducing the impact of wind on irrigation. The bottom end of the annular plate 202b is symmetrically fixedly connected with a long strip of connecting block 202e, and the connecting block 202e is correspondingly slidably connected in the annular hole 202a. The bottom end of the connecting block 202e is fixedly connected with an annular bar 202f. Therefore, when the annular plate 202b rotates, the annular bar 202f on the connecting block 202e is driven to rotate. Six groups of connecting plates 202g are fixedly connected in a circular shape on the outer wall of the annular bar 202f, and circular plates 202h are fixedly connected between the six groups of connecting plates 202g. It can be seen from the above that the annular bar 202f drives the circular plate 202h in the connecting plate 202g to rotate.

[0064] The offset member 203 includes a sliding plate 203b, a sliding rod and a connecting plate 202g; the connecting plates 202g are evenly distributed horizontally on the annular strip 202f, and a sliding hole 203e is provided on the connecting plate 202g; the inner top surface of the annular shield 106 is provided with a sliding groove 203a, which is opened in a circle, and the two adjacent groups of sliding grooves 203a are symmetrically arranged, and the two adjacent groups of sliding grooves 203a intersect with each other, and the angle between the two adjacent groups of sliding grooves 203a is an obtuse angle; both ends of the sliding plate 203b are slidably matched with the corresponding sliding grooves 203a and sliding holes 203e through sliding rods, which are used to control the size of the outlet flow of the nozzle 105; the sliding rods at both ends are coaxial and form an integrated structure with the sliding plate 203b.

[0065] More specifically, if Figure 4 As shown, the sliding plate 203b includes abutting surface I 203c and abutting surface II 203d. There is an acute angle between the abutting surface I 203c and the abutting surface II 203d. Adjacent sliding plates 203b are fitted together through the abutting surfaces I 203c and II 203d. There are six sliding plates 203b.

[0066] like Figure 5 As shown, the inner wall of the annular shield 106 is provided with six groups of long strip-shaped sliding grooves 203a in a circumference, and two adjacent groups of sliding grooves 203a intersect with each other. Each sliding groove 203a is correspondingly connected with a sliding plate 203b, and the sliding plate 203b only slides in its corresponding sliding groove 203a.

[0067] The photovoltaic power generation system is mainly composed of photovoltaic modules, controllers, inverters and batteries. The specific working process is: sunlight shines on the photovoltaic modules, the photovoltaic cells absorb light energy and generate direct current, and the generated direct current is transmitted to the controller through wires. The controller manages and regulates the direct current, and the controller transmits the direct current to the inverter. The inverter converts the direct current into alternating current, and the converted alternating current is transmitted to the motor 201b through a cable to provide power for the motor 201b. When there is sufficient light, the excess electric energy will be stored in the battery through the controller; when there is insufficient light or at night, the battery will power the motor 201b through the inverter.

[0068] Working principle: As can be seen from Example 1, when the wind sensor detects that the wind force exceeds level 4, the staff sends a command through the external controller to adjust the motor 201b to operate, so that the gear 201c at the end of the rotor shaft of the motor 201b rotates. Since the gear 201c is engaged with the ring gear 202c, it drives the annular plate 202b outside the ring gear 202c to rotate. When the annular plate 202b rotates, it drives the annular bar 202f on the connecting block 202e to rotate. When the annular bar 202f rotates, it drives the circular plate 202h on its connecting plate 202g to rotate synchronously, and the sliding The movable rod 203f rotates in the sliding hole 203e and the sliding groove 203a. Due to the offset of the sliding hole 203e, the sliding plate 203b on the sliding rod 203f moves in the sliding groove 203a, and the adjacent sliding plates 203b are fitted together through the abutment surface I 203c and the abutment surface II 203d. In this way, the size of the opening 107 in the annular shield 106 is adjusted, thereby controlling the internal flow of the annular shield 106. In this way, in the case of strong winds, the opening 107 is reduced. The reduction of the opening 107 makes the sprinkler irrigation more concentrated, thereby reducing the impact of wind on irrigation.

[0069] Example 2

[0070] Based on the first embodiment, the irrigation device of the present invention further includes an adjustment mechanism 300 for extending the protection height and an expansion mechanism.

[0071] The adjustment mechanism 300 includes a resisting member 301, a movable member 302 and an adjusting member 303; Figure 6 As shown, several resistance members 301 are arranged at the bottom end of the annular member 202, one end of the movable member 302 is connected to the adjusting member 303, and the other end extends from the outer circumferential surface of the annular shield 106, and a slot 302c is provided at the upper end of the movable member 302 for the resistance member 301 to pass through; the adjusting member 303 is arranged inside the annular shield 106, and when the resistance member 301 rotates with the annular member 202, the movable member 302 moves back and forth in a straight line, driving the adjusting member 303 to expand or contract, and the adjusting member 303 extends from the annular shield 106 after expansion.

[0072] The expansion mechanism 400 includes a moving part 401 arranged on the inner wall of the annular shield 106 and an auxiliary part 402 arranged at the bottom end of the annular part 202. The moving part 401 and the auxiliary part 402 cooperate to supplement the gap portion of the adjacent adjustment part 303 extending out of the annular shield 106, and at the same time fill the gap between the annular shield 106 and the adjustment part 303, thereby further avoiding the influence of wind on irrigation.

[0073] Specifically, the resistance member 301 includes a connecting rod 301a arranged in a circle at the bottom end of the annular plate 202b, and an annular edge 301b arranged at the bottom end of multiple groups of connecting rods 301a; a reducing portion 301c is arranged on the outer wall of the annular edge 301b along the circumferential direction, and the reducing portion 301c is composed of an arc surface I 301d and an arc surface II 301e.

[0074] like Figure 7 、 Figure 9 As shown, the bottom end of the annular plate 202b is circumferentially fixedly connected with eight groups of long strip-shaped connecting rods 301a, and the bottom ends of the eight groups of connecting rods 301a are fixedly connected with annular edges 301b, which are attached to the outer side of the annular shield 106. It can be seen from Example 1 that when the annular plate 202b rotates, the annular edges 301b on the connecting rods 301a are driven to rotate, and the annular edges 301b drive the reducing portion 301c to rotate synchronously.

[0075] like Figure 8 As shown, the movable part 302 includes a movable plate 302b and a shaft seat II 303c; one end of the movable plate 302b is rotatably connected to the shaft seat II 303c, the shaft seat II 303c is set on the adjusting member 303, and the other end of the movable plate 302b extends out from the annular shield 106; a block 302d is integrally formed at one end of the slot 302c on the movable plate 302b, and the block 302d is correspondingly arranged above the reducing portion 301c; the movable plate 302b is slidably connected to the movable opening 302a set on the bottom end surface of the annular shield 106.

[0076] Adjustment member 303 includes an adjustment plate 303b, axle seat I 303a, and compression springs 303d. The upper end of adjustment plate 303b is rotatably connected to annular shield 106 via axle seat I 303a. Compression springs 303d are symmetrically mounted on the inner wall of the lower end of adjustment plate 303b. These carbon springs are strong and convenient for daily use. Multiple sets of compression springs 303d are correspondingly mounted on the inner wall of annular shield 106. The lower end of adjustment plate 303b is fixedly connected to axle seat II 303c.

[0077] like Figure 3As shown, the bottom end of the annular shield 106 is provided with eight groups of movable openings 302a in a circumferential manner. The movable openings 302a are square-shaped. A movable plate 302b is slidably connected to the movable opening 302a. One side of the movable plate 302b is rotatably connected to the adjustment plate 303b through the shaft seat II 303c. The adjustment plate 303b is connected to the inner wall of the annular shield 106 through two groups of compression springs 303d. A slot 302c is provided on the outer wall of the movable plate 302b. A block 302d is formed integrally with the side wall of the slot 302c. The block 302d is relative to the inner wall of the annular shield 106. The reducing portion 301c is arranged above the reducing portion 301c, and the reducing portion 301c is against the inner side of the block 302d. When the annular edge 301b rotates, the reducing portion 301c squeezes the movable plate 302b, so that the movable plate 302b slides over the arc surface I 301d and the arc surface II 301e, thereby causing the movable plate 302b to reciprocate along the radial direction of the annular shield 106. Since the movable plate 302b is rotatably connected to the adjustment plate 303b, the adjustment plate 303b is expanded or contracted. At the same time, the compression spring 303d is deformed.

[0078] Working principle: When the annular plate 202b rotates, the annular edge 301b at the bottom end of the connecting rod 301a rotates, and the annular edge 301b drives the reducing part 301c to rotate, and the arc surface I301d of the reducing part 301c contacts the inside of the block 302d. When the arc surface I301d contacts the inside of the block 302d, the radius gradually expands, thereby driving the movable plate 302b to slide in the movable opening 302a. At this time, the movable plate 302b is rotatably connected to the adjustment plate 303b through the shaft seat II303c, and the adjustment plate 303b is rotatably connected to the inner wall of the annular shield 106 through the shaft seat I303a. At this time, the adjustment plate 303b is in an expanded state, that is, it extends from the bottom end of the annular shield 106 to extend the protection height. At the same time, the compression spring 303d is deformed, and the adjustment plate 303b enhances the windproof effect when expanding.

[0079] When the motor 201b drives the gear 201c to rotate, the gear 201c engages with the ring gear 202c, and the ring gear 202c drives its outer annular plate 202b to rotate. The arc surface I 301d contacts the inside of the block 302d. As its radius gradually decreases, the restoring force driven by the compression spring 303d causes the adjustment plate 303b to rotate, thereby causing the adjustment plate 303b to shrink to the inside of the annular shield 106.

[0080] In summary, in the initial state of this device, its annular shield 106 and adjustment plate 303b block the wind. When the wind increases, the size of the opening 107 of the annular shield 106 is adjusted through the auxiliary mechanism 200 inside, and at the same time the adjustment plate 303b expands to increase the windproof space, thereby reducing the impact of wind on irrigation.

[0081] Furthermore, if Figure 10、 Figure 11 As shown, the moving part 401 includes a tension spring 401b and a moving plate 401c; the inner wall of the annular shield 106 is provided with a mounting groove 401a, and the mounting groove 401a is distributed along its circumferential direction; the tension spring 401b is a carbon spring with high strength and is convenient for daily use. One end of the tension spring 401b is fixed to the top of the inner wall of the mounting groove 401a, and the other end is provided with a moving plate 401c, and the upper end surface of the moving plate 401c is formed with a wedge-shaped portion 401d.

[0082] The auxiliary member 402 includes an auxiliary block 402a provided on the annular member 202 and a resisting portion 402b provided at the bottom end of the auxiliary block 402a. The resisting portion 402b is correspondingly matched with the wedge-shaped portion 401d.

[0083] Eight groups of mounting grooves 401a are symmetrically arranged on the inner side of the annular shield 106. A movable plate 401c is fixedly connected to the mounting groove 401a by a tension spring 401b. The movable plate 401c moves downward in the vertical direction in the mounting groove 401a, so that the movable plate 401c fills the gap between the adjacent adjustment plates 303b extending out of the annular shield 106. In order to ensure the stability of the movable plate 401c in the vertical direction, a wedge-shaped portion 401d is integrally formed on the upper end of the movable plate 401c. At the same time, an auxiliary block 402a and a resistance portion 402b are correspondingly fixedly connected to the bottom of the annular bar 202f. When the annular bar 202f rotates, the resistance portion 402b on the auxiliary block 402a is driven to contact the wedge-shaped portion 401d, thereby driving the movable plate 401c to move in the vertical direction.

[0084] Working principle: When the annular plate 202b rotates, it drives the annular strip 202f on the connecting block 202e to rotate. At this time, the annular strip 202f drives the interference portion 402b on the auxiliary block 402a to rotate at the same time. When it rotates, the interference portion 402b contacts the wedge-shaped portion 401d, thereby squeezing the movable plate 401c, causing the movable plate 401c to move in the vertical direction, and at the same time, the tension spring 401b is deformed. When the movable plate 401c moves downward, as shown in FIG. Figure 9 As shown, the gap between the adjacent adjustment plates 303b extending out of the annular shield 106 is filled. When the annular plate 202b rotates, the abutment portion 402b no longer abuts against the wedge portion 401d, and the movable plate 401c is driven to reset under the restoring force of the tension spring 401b.

[0085] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
