Technical Field

[0001] The invention belongs to the technical field of irrigation, and in particular relates to a water-saving irrigation device. Background Art

[0002] Water-saving irrigation is an irrigation measure that uses the least amount of water to obtain the maximum output or benefit, that is, to maximize the crop yield and output value per unit of irrigation water. The main measures of water-saving irrigation include channel anti-seepage, low-pressure pipe irrigation, sprinkler irrigation, micro-irrigation and irrigation management system. In addition, there are drip irrigation, sub-membrane drip irrigation, center pivot sprinkler irrigation, translation sprinkler irrigation, micro-sprinkler irrigation and other irrigation forms with high irrigation water utilization coefficients; it is an efficient water-saving irrigation method that drips water to the roots of plants through drip irrigation pipes, reducing water evaporation and soil loss. The drip irrigation system is usually composed of a series of drip irrigation pipes, filters, pressure regulators and drip irrigation heads, which can accurately control the amount of water according to the needs of plants. This method is very suitable for irrigation of orchards and vegetable gardens.

[0003] After searching, the patent application document with the prior art publication number CN208191685U proposes a water-saving irrigation device, including a support plate, a first electric telescopic rod is fixedly provided on one side of the top of the support plate, a crossbeam is fixedly provided on the top of the first electric telescopic rod, a slide rail is installed inside the crossbeam, a plurality of pulleys are slidably connected to the slide rail, a fixing rod is fixedly provided at the bottom end of the pulley, a water storage tank is fixedly connected at the bottom end of the fixing rod, a connecting pipe is fixedly provided at the bottom end of the water storage tank, and the bottom of the connecting pipe is sleeved with the middle part of the rotating sprinkler. The utility model facilitates the adjustment of the height of the crossbeam through the first electric telescopic rod, thereby facilitating irrigation in areas of different heights. The position of the rotating sprinkler can be moved through the cooperation of the slide rail and the pulley, thereby carrying out irrigation in multiple positions. The rotating sprinkler can achieve large-scale irrigation and improve the efficiency of irrigation. The water collecting trough is used to store rainwater and irrigation water, and the water leaked or dripped from the rotating sprinkler can achieve the effect of water saving.

[0004] Compared with the above-mentioned documents, in the above-mentioned documents, although the height of the crossbeam is adjusted conveniently by the first electric telescopic rod, so as to facilitate irrigation in areas of different heights, the position of the rotating nozzle can be moved by the cooperation of the slide rail and the pulley, so as to carry out irrigation in multiple positions, and the rotating nozzle is used to irrigate a large area, thereby improving the efficiency of irrigation.

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.

[0028] Embodiment 1

[0029] like Figure 1 , Figure 2 , Figure 3, Figure 4 , Figure 5 As shown, a water-saving irrigation device includes a water tank 1 and a plurality of supporting legs 2 installed at the bottom of the water tank 1, and also includes:

[0030] The water outlet filtering mechanism is used to filter the irrigation water discharged from the water storage tank 1 for use. The water outlet filtering mechanism is located at the bottom of the outer wall of the water storage tank 1. The water outlet filtering mechanism includes a water suction pump 3 installed at the bottom of the outer wall of the water storage tank 1. A water outlet pipe 301 connected to the inside of the water suction pump 3 is fixedly installed on one side of the water suction pump 3. A fixed vertical plate 3011 is fixedly installed inside the water outlet pipe 301. A rotating shaft 302 is rotatably connected to the fixed vertical plate 3011. A driving impeller 303 is fixedly installed on the outer wall of the rotating shaft 302. A square chute 304 is provided at the top of the inner wall of the water outlet pipe 301, a limiting cross bar 305 is fixedly connected inside the square chute 304, a telescopic spring 306 is fixedly connected to one side of the inner wall of the square chute 304, a limiting slider 307 is slidably connected to the outer wall of the limiting cross bar 305, a filter screen plate 308 is fixedly connected to one side of the limiting slider 307, a plurality of rotating plates 309 are fixedly connected to the outer wall of the rotating shaft 302, and a plurality of cleaning brushes 3010 are connected to one side of the plurality of rotating plates 309;

[0031] The present invention further specifically describes that the outer wall of the filter screen plate 308 and the inner wall of the water outlet pipe 301 are slidably fitted, the outer wall of the limit slider 307 and the inner wall of the square slide 304 are slidably fitted, the end of the telescopic spring 306 away from the square slide 304 is connected to the limit slider 307, and the telescopic spring 306 is sleeved on the outer wall of the limit cross bar 305, the filter screen plate 308 and the rotating shaft 302 are slidably arranged, and a plurality of cleaning brushes 3010 are fitted with the outer wall of the filter screen plate 308 and extend into the mesh inside the filter screen plate 308;

[0032] As can be seen from the above, when the staff uses this device for irrigation, they turn on the water suction pump 3 to make it work. When the water suction pump 3 works, the water inside the water storage tank 1 can be sucked into the inside of the water outlet pipe 301 through the water suction pump 3, and then enter the inside of the drip pipe 4 through the filtration of the filter plate 308, and finally flow out through the drip holes on the outer wall of the drip pipe 4;

[0033] When the water sucked out by the water suction pump 3 enters the interior of the water outlet pipe 301, the driving impeller 303 can be driven to rotate according to the impact of the water flow, and the rotating shaft 302 is driven to rotate accordingly, and the multiple rotating plates 309 and multiple cleaning brushes 3010 on the outer wall of the rotating shaft 302 are driven to rotate to clean the impurities on the outer wall of the filter screen plate 308. Through the arrangement of the above structure, the filter screen plate 308 can be used to filter the water sucked out from the inside of the water storage tank 1, and impurities can be prevented from entering the inside of the drip pipe 4 and adhering to the drip holes, thereby avoiding the clogging of the drip holes, which is beneficial to the use of the drip holes for irrigation and improving the irrigation efficiency. In addition, the multiple cleaning brushes 3010 rotate to clean the impurities on the outer wall of the filter screen plate 308, which can reduce the adhesion of impurities on the outer wall of the filter screen plate 308, and correspondingly improve the irrigation efficiency of the filter screen plate 308 for sucking out the water from the inside of the water storage tank 1 for irrigation.

[0034] It should be noted that: a plurality of drip holes are provided on the outer wall of the drip pipe 4 .

[0035] Embodiment 2

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, one end of the water outlet filtering mechanism is connected to a rotating drip irrigation mechanism for performing rotary drip irrigation on the irrigated ground. The rotating drip irrigation mechanism includes a drip pipe 4. The outer wall of the outlet pipe 301 is connected to a connecting rope 401. The end of the connecting rope 401 away from the outlet pipe 301 is connected to a mounting magnetic rod 402. The interior of the drip pipe 4 is fixedly connected to a mounting vertical plate 403. The interior of the mounting vertical plate 403 is provided with a mounting cavity 404. The interior of the mounting cavity 404 is slidably connected to a sliding magnetic plate 406. The sliding magnetic plate 406 is connected to the outer wall of the outlet pipe 301. 06 is fixedly installed with a sliding rod 407 at the bottom, and tension springs 408 are fixedly connected to the outer walls of the sliding rod 407 on both sides, and a sliding magnetic block 409 is fixedly installed at one end of the sliding rod 407 away from the sliding magnetic plate 406, and a limited sliding groove is provided on the outer wall of the rotating shaft 302, and a plug hole is provided inside the limited sliding groove, and a mounting magnetic block 4010 is fixedly connected inside the plug hole, and a plug hole 405 is provided on the water outlet pipe 301 and the drip pipe 4, and the plug hole 405 extends to the inside of the mounting cavity 404;

[0037] The present invention is further specifically described in detail, the installation magnetic rod 402 and the sliding magnetic plate 406 are arranged with opposite poles attracting each other, the installation magnetic rod 402 and the plug hole 405 are arranged for sliding, a sliding opening is opened on the installation vertical plate 403, the sliding opening and the rotating shaft 302 are arranged for corresponding sliding, the sliding rod 407 slides and extends to the inside of the sliding opening at one end away from the sliding magnetic plate 406, the outer wall of the sliding magnetic block 409 and the inner wall of the limiting sliding groove are arranged for sliding fit, the sliding magnetic block 409 and the installation magnetic block 4010 are arranged for corresponding opposite poles attracting each other, the sliding rod 407 and the plug hole are arranged for corresponding sliding plugging, the outer wall of the sliding magnetic plate 406 and the inner wall of the installation cavity 404 are arranged for sliding fit, and the end of the tension spring 408 away from the sliding rod 407 is connected to the bottom of the installation cavity 404;

[0038] As can be seen from the above, when installing the dripping pipe 4, the dripping pipe 4 is slidably inserted into the inside of the water outlet pipe 301, and the filter screen plate 308 is slid and squeezed, so that the sliding opening on the installation vertical plate 403 slides correspondingly with the rotating shaft 302, and the sliding rod 407 slides correspondingly with the limiting sliding groove on the outer wall of the rotating shaft 302. When the sliding rod 407 corresponds to the jack, according to the effect of the opposite poles of the sliding magnetic block 409 and the installation magnetic block 4010 attracting each other, the sliding rod 407 can be inserted into the inside of the jack, so that the dripping pipe 4 is connected and fixed with the rotating shaft 302, so that the dripping pipe 4 is installed on the water outlet pipe 301;

[0039] By setting the above structure, the automatic plugging of the sliding rod 407 and the jack simplifies the installation operation between the dripping pipe 4 and the water outlet pipe 301, and is convenient for the staff to disassemble and replace the dripping pipe 4. In the initial state, the filter screen plate 308 is located at the end of the water outlet pipe 301, so that when the dripping pipe 4 is not installed with the water outlet pipe 301, the inside of the water outlet pipe 301 can be sealed to prevent impurities from entering the inside of the water outlet pipe 301 and causing damage to the inside of the water outlet pipe 301.

[0040] It should be noted that the bottom end of the sliding rod 407 is not plugged into the position of the socket in the initial state, and is only plugged into the inside of the socket when the sliding magnetic block 409 corresponds to the mounting magnetic block 4010;

[0041] When the dripping pipe 4 is disassembled, after the dripping pipe 4 is installed, the two plug holes 405 are aligned, and then the installation magnetic rod 402 is inserted into the inside of the plug hole 405, so that the installation magnetic rod 402 and the sliding magnetic plate 406 are attracted to each other, and then the sliding magnetic plate 406 and the sliding rod 407 are pulled upward to disengage the sliding rod 407 from the plug hole until the sliding rod 407 extends to the outside of the plug hole 405, so that the sliding rod 407 and the sliding magnetic plate 406 are disengaged, and then the water outlet pipe 301 can be removed;

[0042] After the drip pipe 4 is installed, it can be fixed to the rotating shaft 302. When the rotating shaft 302 rotates, the drip pipe 4 is driven to rotate, so that the irrigation water flowing out of the drip holes on the drip pipe 4 is rotated and sprayed out. Through the drip pipe 4, it can be ensured that the irrigation water can evenly cover different areas of the crop, avoiding growth restrictions in certain areas due to insufficient irrigation. For different types of crops, the rotary drip irrigation can be adjusted according to the growth needs and spatial distribution of the crops, providing more accurate irrigation services.

[0043] It should be noted that the outer wall of the drip pipe 4 and the inner wall of the outlet pipe 301 are slidably fitted.

[0044] Furthermore, the present design is applied to the field of water-saving irrigation. By utilizing the function of the filter screen 308, the water sucked out from the water storage tank 1 can be filtered to prevent impurities from entering the interior of the drip pipe 4 and adhering to the drip holes, thereby avoiding the clogging of the drip holes, facilitating the use of the drip holes for irrigation, and improving the irrigation efficiency. In addition, the multiple cleaning brushes 3010 rotate to clean the impurities on the outer wall of the filter screen 308, which can reduce the adhesion of impurities on the outer wall of the filter screen 308, and correspondingly improve the irrigation efficiency of the filter screen 308 for sucking out water from the inside of the water storage tank 1 for irrigation.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
