DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] See also Figure 1-10The present invention provides a PE pipe automatic water intake device 10 for agricultural irrigation, comprising: a pipe body 20, a filter mechanism 30 and a bottom cover 40. The pipe body 20 is used to be connected to a water pump to extract water from a water intake point to irrigate farmland. The filter mechanism 30 is arranged in the pipe body 20, located on the water flow path of the pipe body 20, and is detachably connected to the pipe body 20, and is used to filter the water flow. The bottom cover 40 is arranged on the pipe body 20 and is connected to the filter mechanism 30, so that the filter mechanism 30 can be pulled out of the pipe body 20 through the bottom cover 40 for replacement and cleaning. The water flow in the pipe body 20 is filtered by the filter mechanism 30, and impurities in the water flow removed from the water intake point can be filtered out. At the same time, the filter mechanism 30 can be pulled out by the bottom cover 40, so that the filter mechanism 30 can be easily replaced.

[0033] Specifically, the pipe body 20 includes a water inlet pipe 21 and a water outlet pipe 22. One end of the water inlet pipe 21 is connected to the water source at the water intake point to facilitate water intake. A water outlet 221 and a sewage outlet 222 are provided on the water outlet pipe 22, and a support seat 23 is provided on the inner wall between the water outlet 221 and the sewage outlet 222. The end of the water inlet pipe 21 away from the water intake point is connected to the water outlet pipe 22, and the connection point is located between the support seat 23 and the sewage outlet.

[0034] The filter mechanism 30 includes a filter plate 31 and a fixing assembly 32 . The filter plate 31 is located on a side of the support seat 23 close to the sewage outlet 222 . The fixing assembly 32 is engaged with the support seat 23 to fix the filter plate 31 on the water flow path of the outlet pipe 22 .

[0035] The bottom cover 40 is connected to the sewage outlet 222 and is connected to the fixing assembly 32 to open or close the sewage outlet. After opening the sewage outlet 222, the fixing assembly 32 can be pulled out of the water outlet pipe to replace the filter plate 31. When in use, the water intake is connected to the water intake point, and then the bottom cover 40 is unscrewed, the filter plate 31 is placed on the support seat 23, and then the fixing assembly 32 is clamped on the support seat 23 to fix the filter plate 31, and then the water pump is turned on to pump water. By setting the filter plate 31, the fixing assembly 32 and the bottom cover 40, the water quality can be filtered, and it is convenient to disassemble and repair.

[0036] Furthermore, the support seat 23 is an annular structure, and a rectangular clamping hole 231 is provided on the support seat 23, and the rectangular clamping hole 231 penetrates the support seat 23. The fixing assembly 32 includes a filter plate baffle 321 and a rubber gasket 322. The filter plate baffle 321 is annular, and a support column 3212 is provided on a surface close to the support seat 23. One end of the support column 3212 is rotatably connected to the filter plate baffle 31, and a rectangular clamping block 3211 is provided on the end away from the filter plate baffle 31. The rectangular clamping block 3211 is adapted in shape to the rectangular clamping hole 231. The rubber gasket 322 is annular, and its inner ring is sleeved on the filter plate baffle 321, and the outer ring is in contact with the inner wall of the outlet pipe 22.

[0037] It can be understood that in the initial state, the rectangular stopper 3211 is parallel to the length direction of the rectangular hole 231. At this time, the support column 3212 and the rectangular stopper 3211 can be passed through the rectangular hole 231 at the same time, and then the support column 3212 is rotated to make the length direction of the rectangular stopper 3211 and the length direction of the rectangular hole 231 form an angle. The rectangular stopper 3211 can be used to connect the filter plate baffle 321 to the side of the support seat 23 close to the sewage outlet 222, and the filter plate baffle 321 is used to cooperate with the support seat 23 to clamp the filter plate 31, so as to fix the filter plate on the water flow path of the outlet pipe 22.

[0038] It can be understood that in this embodiment, by arranging the support seat 23 and the filter plate baffle 321 in a ring shape, and the diameter of the filter plate 31 is adapted to the filter plate baffle 321 and the support seat 23, after the filter plate baffle 321 is connected to the support seat 23, the filter plate 31 is clamped between the two, and the filter plate 31 does not interfere with the support column 3212, so that when the water flows through the outlet pipe 22, it can only flow through the filter plate 31, thereby achieving the effect of filtering the water flow.

[0039] It can be understood that the diameter of the support column 3212 is smaller than the width of the rectangular hole 231 so that the support column 3212 can pass through the rectangular hole 231 .

[0040] Furthermore, the length of the support column 3212 is equal to the sum of the thickness of the support seat 23 and the thickness of the filter plate 31, so that after the filter plate 31 is clamped and fixed by the filter plate baffle 321 and the support seat 23, its two sides are respectively in contact with the filter plate baffle 321 and the support seat 23.

[0041] It can be understood that in some embodiments, the length of the support column 3212 can also be greater than the sum of the thickness of the support seat 23 and the thickness of the filter plate 31. By setting the length of the support column 3212 to be equal to the sum of the thickness of the support seat 23 and the thickness of the filter plate 31, after the filter plate 31 is fixed, the support seat 23 and the filter plate baffle 321 can be used to clamp the periphery of the filter plate 31, thereby making the filter plate 31 more stable.

[0042] Furthermore, the number of the rectangular locking holes 231 is plural, and the number of the supporting columns 3212 and the rectangular locking blocks 3211 is also plural, and is the same as the number of the rectangular locking holes 231 .

[0043] Furthermore, a slot 232 is provided on one side of the support seat 23 close to the water outlet 221. A buckle 3201 is provided on one side of the rectangular block 3211 close to the support column. When the rectangular block 3211 is rotated to be perpendicular to the rectangular hole 231, the buckle 3021 is engaged with the slot 232.

[0044] It can be understood that by providing the card slot 232 and the buckle 3201, the stability of the connection between the filter plate baffle 321 and the support seat 23 can be increased.

[0045] Furthermore, there are two card slots 232, which are respectively located on opposite sides of the length direction of the rectangular card hole 231 and are mirror-imaged. There are two clips 3201, which are respectively located on opposite sides of the width direction of the rectangular card block 3211 and are mirror-imaged.

[0046] Furthermore, the support column 3212 penetrates the filter plate baffle 321 and extends to a side of the filter plate baffle 321 that is protruding away from the support seat 23 .

[0047] It can be understood that the support column 3212 can be rotated by spitting out one end of the filter plate baffle 321 through the support column 3212.

[0048] Furthermore, the bottom cover 40 includes a bottom cover shell 41 and a sewage discharge mechanism 42. The bottom cover shell 41 is a cavity with a hollow interior and an opening on one side, which is connected to the sewage discharge port 222, and the opening is connected to the sewage discharge port 222. A first fan-shaped opening 411 that penetrates the bottom cover shell 41 is provided on a surface of the bottom cover shell 41 away from the opening. The sewage discharge mechanism 42 is rotatably connected to the bottom cover shell 41 and rotates relative to the bottom cover shell 41 to open or close the first fan-shaped opening 411.

[0049] It can be understood that when the bottom cover 40 is not opened, the sewage discharge mechanism 42 can be rotated to open the first fan-shaped opening 411 for sewage discharge.

[0050] It can be understood that the connection between the bottom cover shell 41 and the sewage outlet 222 can be through a threaded connection.

[0051] Furthermore, the sewage discharge mechanism 42 includes a rotating baffle 421 and a connecting shaft 422. The connecting shaft 422 passes through a side of the bottom cover shell 41 away from its opening and is rotatably connected to the bottom cover shell 41. The rotating baffle 421 is connected to the connecting shaft 421 to achieve a rotating connection with the bottom cover shell 41 through the connecting shaft 421.

[0052] Furthermore, a second fan-shaped opening 4211 is formed on the rotating baffle 421 , and the shape of the second fan-shaped opening 4211 matches the shape of the first fan-shaped opening 411 .

[0053] It can be understood that when the rotating baffle 421 rotates relative to the bottom cover shell 41, when the second fan-shaped opening 4211 is rotated to communicate with the first fan-shaped opening 411, the first fan-shaped opening 411 is opened, otherwise, the first fan-shaped opening 411 is closed.

[0054] It can be understood that in the present embodiment, the bottom cover shell 41 and the filter plate baffle 321 are connected by a flexible rope of sufficient length. When the filter plate 31 needs to be replaced, the bottom cover shell 41 is opened, and the support column 3212 is rotated from the sewage outlet 222 to rotate the length direction of the rectangular clamp 3211 to be parallel to the length direction of the rectangular clamp hole 231, and then the bottom cover shell 41 is pulled to bring the filter plate baffle 321 out of the sewage outlet 222 through the flexible rope.

[0055] It can be understood that, since the filter plate baffle 321 is outer-coated with the rubber gasket 322 , when the outlet pipe is slightly deformed, the filter plate baffle 321 can be removed from the sewage outlet 222 by the elastic deformation of the rubber gasket 322 .

[0056] Furthermore, the pipe body 20 is also provided with a heat-insulating layer, which is sleeved on the outside of the pipe body 20 .

[0057] By providing a heat-insulating layer, the device can be applied to a wider range of scenarios and will not be frozen when used in winter.

[0058] Furthermore, the water inlet pipe 21 of the pipe body 20 includes a water intake portion 211 and a water delivery portion 212, one end of the water intake portion 211 is connected to the water intake point, and the other end is connected to the water delivery portion 212, and there is an angle between the water intake portion 211 and the water delivery portion 212, and the water delivery portion 212 is connected to the water outlet pipe 22. By setting the angle, it is more convenient to take water in the device, and water can be taken without tilting the water inlet pipe 21.

[0059] When in use, first remove the bottom cover 40, then place the filter plate 31 on the support seat 23, and insert the rectangular stopper 3211 of the filter plate baffle 321 in the fixing assembly 32 into the rectangular hole 231 on the support seat 23, then rotate the support column 3212, and the support column rotates so that the buckle 3201 on the rectangular stopper 3211 is buckled into the slot 222 on the support seat to fix the filter plate 31, and then screw the bottom cover 40 on for use. During use, impurities in the water will accumulate in the inner cavity of the bottom cover due to gravity and water flow. At this time, the rotating baffle 421 can be rotated by a certain angle according to the situation, so that the first fan-shaped opening 411 on the bottom cover housing 41 and the second fan-shaped opening 4211 on the rotating baffle 421 have overlapping parts, thereby discharging impurities. When it is necessary to replace the filter plate 31 or clean impurities that are difficult to discharge, it is only necessary to open the bottom cover 40, rotate the support 3212 in the opposite direction, and replace the filter plate 31.

[0060] Compared with the prior art, the PE pipe automatic water intake device for agricultural irrigation provided by the present invention has at least the following beneficial effects:

[0061] Remove the bottom cover, install the filter plate and fixing components, and then install the bottom cover for easy replacement and maintenance. During use, the rotating baffle of the bottom cover can be rotated to discharge the sludge without stopping the entire operation. When conducting agricultural irrigation, the user can easily filter the water and discharge impurities.

[0062] The specific implementation methods of the present invention described above do not constitute a limitation on the protection scope of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the protection scope of the present invention.
