DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0021] Specific implementation examples Figure 1 As shown, the utility model is a salt water irrigation treatment unit replacement mechanism, including a filter element 1 tube provided with a filter element 1, the filter element 1 tube is connected in series between a water inlet pipe and a water outlet pipe, the replacement mechanism includes a replacement wheel 2 and a clamping device, a plurality of sleeves 3 are provided on the rim of the replacement wheel 2, the filter element 1 tube is sleeved in the sleeve 3, the clamping device includes a telescopic bellows 4, a first top tightening flange 5, a second top tightening flange 6 and a telescopic cylinder 7, the telescopic bellows 4 is connected between the water outlet pipe and the first top tightening flange 5, the second top tightening flange 6 is communicated with the water outlet pipe, the first top tightening flange 5 and the second top tightening flange 6 are respectively arranged on both sides of the filter element 1 tube, the telescopic cylinder 7 pushes the first top tightening flange 5 to squeeze the filter element 1 tube, and the filter element 1 tube is pressed and fixed to the second top tightening flange 6 on the other side, and the filter element 1 tube is clamped and sealed by means of the first top tightening flange 5 and the second top tightening flange 6.

[0022] When the replacement mechanism is in use, the filter element 1 tube is inserted into the sleeve 3, and the first tightening flange 5 is used to push one end of the filter element 1 tube with the help of the telescopic cylinder 7, so that the filter element 1 tube moves and the other end thereof touches the second tightening flange 6. The first tightening flange 5 and the second tightening flange 6 are respectively provided with sealing grooves adapted to the shape of the end portion of the filter element 1 tube. With the help of clamping of the first tightening flange 5 and the second tightening flange 6, the second tightening flange 6 is installed at the output end pipe mouth of the spiral filter, so that the filter element 1 tube is connected with the inlet and outlet water ends of the secondary filtration device.

[0023] Further, such as Figure 2 As shown, the replacement mechanism also includes a rotating wheel mechanism, which includes a base 8, a slide rail assembly, a swing rod 9 and a rake rod 10. The slide rail assembly is arranged on the base 8, and the slide rail assembly includes a first slide rail 11 and a second slide rail 12. The first slide rail 11 is provided with a first slider 13, and the second slide rail 12 is provided with a second slider 14. The first slide rail 11 and the second slide rail 12 are arranged at a right angle, and the swing rod 9 is a right-angle structure. The right angle of the swing rod 9 is hinged to the base 8. The two ends of the swing rod 9 are respectively hinged to the first slider 13 and the second slider 14. The first slider 13 is fixedly connected to the first tightening flange 5. The rake rod 10 is arranged on the second slider 14. The rake rod 10 forms a hook fit with the sleeve 3. The first slider 13 swings the swing rod 9 with the help of the movement of the first tightening flange 5. The swing rod 9 drives the rake rod 10 to move relative to the sleeve 3 on the replacement wheel 2. The replacement wheel 2 has the freedom to rotate relative to the rotating wheel mechanism with the help of the rotating shaft 15 passing through its wheel core.

[0024] When the irrigation efficiency is reduced and the filter element 1 needs to be replaced, the telescopic cylinder 7 moves backward to drive the first tightening flange 5 to retreat, and the first tightening flange 5 and the second tightening flange 6 release the filter element 1 tube, and the first slider 13 moves backward synchronously with the movement of the first tightening flange 5. Figure 2 As shown, the first slider 13 drives the swing rod 9 to rotate, wherein the direction of the second slide rail 12 is perpendicular to the rotation direction of the replacement wheel 2. The swing of the swing rod 9 causes the second sliding block to move downward, causing the rake rod 10 to move downward, and the rake claw 16 hinged on the rake rod 10 is inserted into a sleeve 3 of the replacement wheel 2. As the rake rod 10 continues to move downward, the rake claw 16 pulls the replacement wheel 2, and the used filter element 1 on the replacement wheel 2 is rotated downward, and the spare filter element 1 on the upper side is rotated to the axis of the inlet and outlet pipes of the secondary filtration device. Then, the telescopic cylinder 7 extends out, driving the first tightening flange 5 forward to clamp the spare filter element 1, the first slider 13 moves forward, and the second slider 14 moves upward to drive the rake rod 10 upward. Since the rake claw 16 is as shown in the figure Figure 1 The herringbone shape shown is hinged to the rake rod 10 . When the rake claw 16 moves upward, the rake claw 16 cannot grip the sleeve 3 , thereby achieving the reset of the rake rod 10 .

[0025] The above process is driven only by the telescopic cylinder 7, and the control is simple, and no human intervention is required, which shortens the maintenance time and helps to improve the irrigation efficiency, thereby leaving enough time for salt water salinity adjustment and storage to avoid delaying the farming season.

[0026] Furthermore, a rake claw 16 of a herringbone structure is hingedly connected to the end of the rake rod 10, and the rake claw 16 and the sleeve 3 form a hooking fit. Figure 1 As shown, a limit is set at the hinged position between the end of the rake rod 10 and the rake claw 16, that is, a protrusion is extended from the end of the rake rod 10 before the hinged position, and the protrusion interferes with the rake claw 16. Figure 1 In the state shown, the rake claw 16 interferes with the protrusion and cannot continue to rotate counterclockwise. As the second slider 14 moves downward, the spare filter element 1 tube is pulled to the clamping position with the help of the rake claw 16. When the second slider 14 moves upward, the rake claw 16 is lifted counterclockwise by the sleeve 3 due to the arc-shaped claw piece on the front side and the damping cooperation of the rotating shaft 15 and the replacement wheel 2, thereby avoiding the position of the replacement wheel 2 being moved during the reset stroke.

[0027] like Figure 4 As shown, the filter element 1 tube includes a tube body 17 and a first fixing plug 18 and a second fixing plug 19 disposed at both ends of the tube body 17. The filter element 1 is fixedly connected to the first fixing plug 18 and suspended in the tube body 17. The first fixing plug 18 and the second fixing plug 19 are respectively connected to the tube body 17 in a detachable threaded connection. The first fixing plug 18 and the second fixing plug 19 are in a frustum-shaped structure and are respectively provided with through holes. The filter element 1 is in a cup-shaped structure with one end open. A threaded sleeve is disposed at the opening of the filter element 1. A tubular fixing portion 20 is disposed at the through hole of the first fixing plug 18. The fixing portion 20 is connected to the threaded sleeve of the filter element 1 in a detachable threaded connection.

[0028] The first fixing plug 18 and the second fixing plug 19 with a frustum-shaped structure form a clamping fit with the first tightening flange 5 and the second tightening flange 6 provided with matching grooves, which is convenient for sealing and guiding positioning. Sealing rings are provided on the outer inclined surfaces of the first fixing plug 18 and the second fixing plug 19.

[0029] After replacement, the filter element 1 can be removed with the help of the detachably connected first fixing plug 18 and the second fixing plug 19, and rinsed and cleaned, and the inner wall of the tube body 17 can be cleaned, thereby increasing the number of cycles and reducing the cost of use.

[0030] Furthermore, the first slider 13 and the second slider 14 are respectively provided with raised hinge columns, and the end of the swing rod 9 is provided with an oblong hole to form an articulated match with the hinge columns of the first slider 13 and the second slider 14. With the cooperation of the oblong hole and the hinge column, the first slider 13 and the second slider 14 always maintain transmission cooperation during the rotation of the swing rod 9 to avoid limit jamming.

[0031] Furthermore, a reset spring 21 is provided between the filter element 1 tube and the sleeve 3, a fixing ring 22 is sleeved on the outside of the filter element 1 tube, and the reset spring 219 is connected between the sleeve 3 and the fixing ring 22. After the filter element 1 tube is loosened, the filter element 1 tube is pulled out of the second top-tightening flange 6 with the help of the reset spring 21. This prevents the filter element 1 tube from getting stuck with the second top-tightening flange 6 during the pull-down process of the rake claw 16, thereby reducing the equipment failure rate.
