Description

Technical Field

[0001] The invention relates to the technical field of drip irrigation equipment, and in particular to a water-saving and drought-resistant water storage type drip irrigation equipment. Background Art

[0002] Under natural conditions, some areas often cannot meet the water requirements of wheat due to insufficient precipitation, and artificial drip irrigation is needed for wheat. Drip irrigation uses plastic pipes to send water through holes or drippers on capillary tubes with a diameter of about 10mm to the roots of crops for local irrigation. Drip irrigation is the most effective water-saving irrigation method in arid and water-scarce areas. Through drip irrigation, water is dripped around the wheat root area, which is absorbed quickly. After drip irrigation, the soil is loose and not compacted, which is conducive to root absorption.

[0003] For areas with less precipitation, tap water is generally transported to the drip irrigation area using a water pump. The drip irrigation pipe is laid on the ground to directly provide water to the wheat through drip irrigation. In order to improve the utilization rate of water resources and avoid insufficient water resources for drip irrigation in water-scarce areas, the existing technology collects and stores rainwater through a rainwater collection system. During dry periods, the collected rainwater is drip-irrigated to the wheat through drip irrigation equipment, effectively saving the water resources consumed by drip irrigation.

[0004] As rainwater falls, it is mixed with dust and other substances in the air, causing the collected rainwater to be mixed with impurities. Directly drip irrigation of water mixed with impurities through irrigation equipment is likely to cause rainwater to get stuck in the pipe openings or gaps on the way through multiple pipes, making it difficult to clean. Long-term use will clog the pipes and affect the drip irrigation effect. Summary of the invention

[0058] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0059] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention provides a water-saving and drought-resistant water storage type drip irrigation equipment, including a water pump 1, a main drainage pipe 2 is connected to the drainage end of the water pump 1, a straight main pipe 3 is connected to the end of the main drainage pipe 2, and a plurality of drip irrigation branches 4 are arranged in a linear array in the length direction of the straight main pipe 3.

[0060] A water inlet pipe is connected to the water inlet end of the water pump 1, and the end of the water inlet pipe can be connected to the water storage tank. When the water pump 1 is started, water can pass through the water inlet pipe from the water storage tank and enter the main drainage pipe 2, and then enter the drip irrigation branch pipe 4 after passing through the straight main pipe 3.

[0061] In order to control the water flow, a control valve 20 is installed on the main drainage pipe 2. The control valve 20 can control the water flow entering the drip irrigation branch pipe 4. In practical applications, other valve structures can be installed according to actual conditions, mainly used for uniform distribution and discharge of water flow.

[0062] like Figure 6 As shown, a water collecting pipe 5 is arranged on the side of the drip irrigation branch pipe 4, and the water collecting pipe 5 is parallel to the drip irrigation branch pipe 4. An opening 6 is arranged on the water collecting pipe 5, and a drip irrigation head 7 is installed at the bottom of the water collecting pipe 5. A plurality of drainage heads 8 are installed on the drip irrigation branch pipe 4, and the water outlet of the drainage head 8 is opposite to the opening 6. Water flows from the drip irrigation branch pipe 4 to the drainage head 8, and drips from the drainage head 8 into the water collecting pipe 5, and then is discharged from the drip irrigation head 7.

[0063] A sleeve 9 is arranged in the water collecting pipe 5, and a water collecting port 10 facing the opening 6 and a water outlet 11 facing the drip irrigation head 7 are arranged on the sleeve 9. A filter is arranged at the water outlet 11. The water collecting port 10 and the water outlet 11 can be opened and closed to collect water when the water collecting port 10 is opened and discharge water when the water outlet 11 is opened.

[0064] A support frame 12 is installed at the end of the drip irrigation branch pipe 4 , and one end of the water collecting pipe 5 is installed on the straight main pipe 3 , and the other end is installed on the support frame 12 .

[0065] An opening and closing driving member 13 is installed in the support frame 12 . The opening and closing driving member 13 is connected to the sleeve 9 and can adjust and control the opening and closing states of the water collection port 10 and the water discharge port 11 .

[0066] In the present invention, a water collecting pipe 5 is arranged on one side of each drip irrigation branch pipe 4, and a sleeve 9 for collecting rainwater is arranged in the water collecting pipe 5. When the sleeve 9 opens the water collecting port 10, rainwater can be collected, and when the drain port 11 is opened, rainwater can be discharged, so as to directly perform drip irrigation. Impurities are isolated in the sleeve 9 by the filter screen, and the sleeve 9 is directly cleaned, which effectively reduces the influence of impurities in the rainwater on the drip irrigation process, and improves the water-saving effect under the premise of avoiding impurities blocking the pipeline;

[0067] Furthermore, the drainage head 8 itself can perform drip irrigation downwards, and the water collecting pipe 5 can assist the drainage head 8 of the drip irrigation branch pipe 4 to perform drip irrigation in a larger area, thereby improving the drip irrigation effect.

[0068] Specifically, there are three types of drip irrigation:

[0069] The first is direct drip irrigation with the drainage head 8. This method uses tap water. Under the action of the water pump 1, the tap water flows from the main drainage pipe 2 through the straight main pipe 3 into the drip irrigation branch pipe 4, and then flows to the drainage head 8 through the drip irrigation branch pipe 4. At this time, the drainage head 8 is facing downward or slightly inclined, and the water drops from the drainage head 8 drip irrigate the ground directly below;

[0070] The second type is that the drip irrigation head 7 performs extended-range drip irrigation on tap water. This method uses tap water. Under the action of the water pump 1, the tap water enters the drip irrigation branch pipe 4 after passing through the straight main pipe 3 from the main drainage pipe 2, and flows to the drainage head 8 through the drip irrigation branch pipe 4. At this time, the drainage head 8 is facing the opening 6, and the dripping water drops or smaller water flows into the water collecting pipe 5, and then drips from the drip irrigation head 7 to the ground, realizing drip irrigation on the ground. The drip irrigation position of this drip irrigation method is different from the drip irrigation position of the first drip irrigation method, and can expand the drip irrigation range on the basis of the first drip irrigation method and enhance the drip irrigation effect;

[0071] The third method is to drip irrigation with rainwater by the drip irrigation head 7. This method uses rainwater, which is collected in the casing 9. After the drain port 11 is opened, the rainwater is filtered through the filter screen to the water collecting pipe 5, and then drips onto the ground through the drip irrigation head 7 to achieve drip irrigation on the ground.

[0072] Among the above three methods, when drip irrigation is needed after rainfall, the third method is preferred for drip irrigation of the land.

[0073] In order to realize the above-mentioned different drip irrigation modes, the drip irrigation branch pipe 4 in the present invention is capable of self-rotation. In actual operation, the rotation of the drip irrigation branch pipe 4 is manually adjusted to adjust the facing direction of the drainage head 8. The adjustable design of the drip irrigation branch pipe 4 can realize the adjustment of the drip irrigation range in a small range.

[0074] In the present invention, the water collection port 10 and the water discharge port 11 in the casing 9 can be opened and closed, and can collect rainwater. Specifically, the casing 9 adopts the following preferred embodiments, such as Fig. 9 and Fig.10 As shown, the sleeve 9 includes an inner tube 91 and an outer tube 92 sleeved outside the inner tube 91;

[0075] The outer wall of the inner tube 91 fits with the inner wall of the outer tube 92. A first notch 93 is formed on the outer tube 92 at a position corresponding to the opening 6. A second notch 94 is formed on the inner tube 91 at a position corresponding to the opening 6.

[0076] A third notch 95 is formed on the outer tube 92 and is located opposite to the drip irrigation head 7. A fourth notch 96 is formed on the inner tube 91 and is located opposite to the drip irrigation head 7.

[0077] The filter screen is installed in the third slot 95 , the first slot 93 and the second slot 94 form a water collection port 10 , and the third slot 95 and the fourth slot 96 form a water outlet 11 .

[0078] When rainwater passes through the third notch 95 , impurities in the rainwater will be filtered out, thereby avoiding clogging of the drip irrigation head 7 .

[0079] In order to improve the efficiency of rainwater collection, several additional water collecting pipes 5 and sleeves 9 can be set up. That is to say, in addition to setting a water collecting pipe 5 on the side of each drip irrigation branch pipe 4, multiple additional water collecting pipes 5 can be added to increase the water storage capacity. The water collecting port 10 of the sleeve 9 should be large enough to allow rainwater to enter.

[0080] The first notch 93 and the second notch 94 have the same width, and the third notch 95 and the fourth notch 96 have the same width;

[0081] The first notch 93, the second notch 94, the third notch 95 and the fourth notch 96 have different relative positions in different situations. Specifically, Fig.10 and Fig.11 As shown, when the first notch 93 and the second notch 94 are facing each other, the water collection port 10 is open, and when the first notch 93 and the second notch 94 are staggered from each other, the water collection port 10 is closed;

[0082] When the third notch 95 and the fourth notch 96 are facing each other, the water outlet 11 is open, and when the third notch 95 and the fourth notch 96 are offset from each other, the water outlet 11 is closed;

[0083] When the water collection port 10 is opened, the water outlet 11 is closed, and when the water collection port 10 is closed, the water outlet 11 is opened.

[0084] In the present invention, the relative positions between the first notch 93 and the second notch 94 and between the third notch 95 and the fourth notch 96 are adjusted mainly by the rotation of the inner tube 91 .

[0085] For the second drip irrigation method mentioned above, there are two implementation methods;

[0086] The first embodiment is that the water collection port 10 is closed. At this time, after the water drops onto the sleeve 9, it slides down along the outer wall of the sleeve 9 to the drip irrigation head 7 and is discharged. This embodiment is suitable for drip irrigation scenarios with a small drip irrigation amount.

[0087] The second implementation is that the water collection port 10 is opened and the drain port 11 is closed. At this time, water flows through the drainage head 8 and drips, passes through the water collection port 10 and enters the sleeve 9, and the water flow is collected briefly. This implementation is suitable for short-term collection of water flow when the drip irrigation volume is excessive. It can also be used to collect tap water when the tap water is not turned off in time during rainfall, effectively avoiding the negative impact of excessive drip irrigation in a short period of time on wheat growth.

[0088] In which, when the water collecting port 10 is closed, water drops falling on the sleeve 9 can slide along the outer periphery of the sleeve 9. To achieve this purpose, it is necessary to make the outer diameter of the outer tube 92 smaller than the inner diameter of the water collecting pipe 5 so that there is a gap between the outer wall of the outer tube 92 and the water collecting pipe 5.

[0089] During the rainfall process, after the water in the casing 9 is full, the rainwater gradually gathers into the water collecting pipe 5. The rainwater entering the water collecting pipe 5 will slow down its dripping speed relative to the rainwater falling under normal gravity. After the rainfall is completed, the land can be continuously drip-irrigated to extend the moisture retention time. After the water in the water collecting pipe 5 is exhausted, the drain port 11 is opened to allow the rainwater in the casing 9 to continue drip irrigation.

[0090] In the present invention, the ends of the water collecting pipe 5 and the drip irrigation branch pipe 4 are installed by the support frame 12. Specifically, Figure 5 As shown, the support frame 12 includes a solid rod frame 121 and a hollow pipe frame 122;

[0091] The solid pole frame 121 and the hollow pipe frame 122 are connected, and the height position of the hollow pipe frame 122 is lower than the height position of the solid pole frame 121, wherein the water collecting pipe 5 is arranged obliquely below the drip irrigation branch pipe 4, and the height position of the water collecting pipe 5 is flush with the height position of the hollow pipe frame 122, and the height position of the drip irrigation branch pipe 4 is flush with the height position of the solid pole frame 121.

[0092] In the present invention, the drip irrigation branch pipe 4 can rotate by itself. By adjusting the rotation of the drip irrigation branch pipe 4, the facing direction of the drainage head 8 can be changed. In order to realize the rotatable installation of the drip irrigation branch pipe 4, the present invention makes the following design, such as Figure 6 and Figure 7 As shown, the solid rod frame 121 is connected to the first mounting tube 14, the linear main pipe is connected to the second mounting tube 15, the first mounting tube 14 is directly opposite to the second mounting tube 15, one end of the drip irrigation branch pipe 4 is movably installed in the first mounting tube 14, and the other end is movably installed in the second mounting tube 15, the drip irrigation branch pipe 4 is in close contact with the inner wall of the first mounting tube 14 and the inner wall of the second mounting tube 15, and can rotate around the first mounting tube 14 and the second mounting tube 15.

[0093] The drip irrigation branch pipe 4 is connected to the second installation tube 15 , and the second installation tube 15 is connected to the inside of the straight main pipe 3 . Water in the straight main pipe 3 can enter the drip irrigation branch pipe 4 through the second installation tube 15 .

[0094] To install the water collecting pipe 5, Figure 7 and Figure 8 As shown, a bent rod 16 is connected to the straight main pipe 3 , the bent rod 16 is connected to the end of the water collecting pipe 5 , and the end of the water collecting pipe 5 is fixedly connected to the hollow pipe rack 122 through a connecting piece 17 .

[0095] In the present invention, the opening and closing control of the water collection port 10 and the water discharge port 11 is realized by the rotation of the inner tube 91, wherein the outer tube 92 is fixed and the inner tube 91 is movable. Specifically, Figure 8 , Fig. 9 and Fig.10 As shown, one end of the inner tube 91 is in active contact with the inner wall of the water collecting pipe 5, and the end of the outer tube 92 is fixedly connected to the inner wall of the water collecting pipe 5;

[0096] The end of the inner tube 91 away from the water collecting pipe 5 is connected with a connecting disc 18 , the outer periphery of the connecting disc 18 abuts against the inner wall of the outer tube 92 , and the connecting disc 18 is in active contact with the inner wall of the water collecting pipe 5 .

[0097] In the present invention, the opening and closing driving member 13 is connected to the sleeve 9 and can adjust and control the opening and closing states of the water collection port 10 and the water discharge port 11. The opening and closing driving member 13 of the present invention mainly adopts the following preferred embodiments, such as Figure 5 , Fig.12 As shown, the opening and closing driving member 13 includes a rotating shaft 131 and a gear 132 mounted on the rotating shaft 131;

[0098] The rotating shaft 131 is connected to the center of the connecting disk 18, and the rotating shaft 131 penetrates the outer wall of the water collecting pipe 5 and extends into the hollow pipe frame 122. The hollow pipe frame 122 is provided with an adjusting cavity 133, and the gear 132 is arranged in the adjusting cavity 133;

[0099] A rack 134 is slidably disposed in the adjusting cavity 133, the rack 134 meshes with the gear 132, a sliding seat 135 is disposed at the end of the rack 134, and a connecting spring is connected between the sliding seat 135 and the adjusting cavity 133;

[0100] The end of the hollow pipe frame 122 away from the slide seat 135 is threadedly assembled with a screw rod 136 , one end of the screw rod 136 is connected to a knob 137 , and the other end is connected to a stop block 138 , and the stop block 138 is in close contact with the end of the rack 134 .

[0101] By rotating the knob 137, the screw 136 is driven to rotate, and the screw 136 performs a spiral motion relative to the hollow tube frame 122, driving the stop block 138 to move in the hollow tube frame 122, thereby pushing the rack 134 to move along the inside of the adjustment cavity 133. In the process of the rack 134 moving forward, the gear 132 is driven to rotate, and the connecting disk 18 is driven to rotate through the rotating shaft 131. The connecting disk 18 drives the inner tube 91 to rotate, so that the positions of the second notch 94 and the fourth notch 96 are changed.

[0102] like Fig.10 As shown, assuming that in the initial state, the first notch 93 and the second notch 94 are facing each other, and the third notch 95 and the fourth notch 96 are staggered from each other, after the inner tube 91 is rotated, the first notch 93 and the second notch 94 are gradually staggered from each other, and the third notch 95 and the fourth notch 96 are gradually facing each other, as shown in FIG. Fig.11 As shown, at this time, the water collection port 10 is gradually closed and the water discharge port 11 is gradually opened.

[0103] Among them, the facing cross-section of the third slot 95 and the fourth slot 96 determines the size of the drain 11. When the degree of misalignment between the third slot 95 and the fourth slot 96 is greater, the facing cross-section of the third slot 95 and the fourth slot 96 is smaller, and the drain 11 is smaller. By controlling the rotation angle of the inner tube 91, the size of the drain 11 can be controlled, thereby controlling the flow rate of the drain.

[0104] In the present invention, in order to prevent rainwater in the casing 9 from overflowing to one side, the casing 9 needs to be in a horizontal state. In the early installation process, the inclination of the casing 9 needs to be adjusted. For this, the present invention makes the following design, such as Figure 1 and Figure 5 As shown, at least two support members 19 are installed at the bottom of the hollow pipe rack 122 and the straight main pipe 3;

[0105] The support member 19 includes a support seat 191 and a threaded column 192 connected to the bottom of the support seat 191;

[0106] The support seat 191 is installed at the bottom of the hollow pipe frame 122 and the straight main pipe 3. The threaded seat 193 is threadedly assembled on the threaded column 192, and a plurality of plug rods 194 are installed at the bottom of the threaded seat 193.

[0107] By rotating the threaded seat 193, the height position of the threaded seat 193 on the threaded column 192 can be adjusted to adjust the height of the entire support member 19. First, the height of the entire support member 19 is adjusted, and then the insertion rod 194 is inserted into the soil to a certain depth so that the casing 9, the water collecting pipe 5, the drip irrigation branch pipe 4 and the straight main pipe 3 are in a horizontal state. In actual applications, if the pipeline is tilted, the horizontal state of the pipeline can also be controlled by controlling the insertion depth of the insertion rod 194.

[0108] In addition, during the adjustment process, it is necessary to ensure that the distance between the drainage head 8 and the soil does not exceed a certain range to prevent the drip irrigation height from being too high and the water droplets from deviating from the ideal drip irrigation position under wind force.
