[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The following is combined with Figures 1-5 This application is described in further detail.

[0024] The embodiment of the present application discloses a reverse osmosis membrane replacement tool, including an inner extension plate 1, wherein inner threaded tracks 14 are arranged near both ends of the outer side of the inner extension plate 1, and the diameter of the inner threaded track 14 is the same as the diameter of the positioning bolt 11. A limit plate 15 is rotatably arranged at the bottom of the left end of the inner extension plate 1, and a hidden frame 19 is fixedly arranged at the bottom of the left end of the inner extension plate 1. The specification of the hidden frame 19 is the same as that of the limit plate 15. After the inner extension plate 1 slides inside the outer plate 2 and moves to a specified position, the positioning bolt 11 is rotated, and the positioning bolt 11 is connected to the inner threaded track 14 through the positioning bolt 11 and the inner threaded track 14. The inner extension plate 1 is fixed to the inner extension plate 1 by the hidden frame 19, and the limit plate 15 is convenient for folding up the limit plate 15 after rotation to avoid damage to the limit plate 15 when folding. A fixed circular groove is fixedly provided in the middle of one side of the limit plate 1 close to the inner extension plate 1, and a rubber suction cup 16 is fixedly provided inside the fixed circular groove through a connecting rod. The diameter of the rubber suction cup 16 is smaller than the diameter of the fixed circular groove. The limit plate 15 contacts the frame of the reverse osmosis membrane through the inner rubber suction cup 16 in a vertical state, and is tightly adsorbed to the frame through the circular inner side of the rubber suction cup 16, thereby ensuring the stability of the tool when in use.

[0025] The right end of the inner extension plate 1 is slidably sleeved with the outer plate 2, and the outer plate 2 is set to a semicircular arc. The outer plate 2 and the inner extension plate 1 are set concentrically. The outer plate 2 and the inner extension plate 1 are set concentrically to facilitate the contraction of the inner extension plate 1 into the inside of the outer plate 2, thereby realizing the folding processing of the tool. Both sides of the left end of the outer plate 2 are threadedly inserted with positioning bolts 11, and the inner extension plate 1 after movement is fixed by the positioning bolts 11, so that the inner extension plate 1 and the outer plate 2 are fixed as a whole.

[0026] The inner side of the right end of the outer plate 2 is slidably sleeved with a U-shaped moving frame 7, and a telescopic slide rod 8 is fixedly arranged on the top of the inner wall of the U-shaped moving frame 7. The setting of the telescopic slide rod 8 ensures that the pulley 10 at the bottom can adapt to the outer plate 2 and the inner extension plate 1 of different heights, so that the upper U-shaped moving frame 7 can slide smoothly at different heights. A pad 9 is fixedly arranged at the bottom of the telescopic slide rod 8, and a pulley 10 is rotatably arranged at the bottom of the pad 9. The roller surface at the bottom of the pulley 10 is slidably connected to the upper surface of the edge position of the outer plate 2, and the U-shaped moving frame The number of 7 is two, and an arc-shaped toggle plate 6 is arranged between the two U-shaped moving frames 7. The arc-shaped toggle plate 6 is used to move the frame of the reverse osmosis membrane out of its original position to achieve the effect of replacing the reverse osmosis membrane. The arc-shaped toggle plate 6 is arranged as a semicircular plate, and an arc-shaped rod 17 is fixedly inserted at the bottom of the arc-shaped toggle plate 6. The bottom of the outer side of the arc-shaped rod 17 is slidably connected to the upper surface of the outer plate 2. The arrangement of the arc-shaped rod 17 ensures that the arc-shaped toggle plate 6 can slide evenly on the inner side of the outer plate 2, so that the force applied by the tool when replacing the reverse osmosis membrane can be even.

[0027] A support plate 18 is fixedly provided in the middle of the outer side of the U-shaped moving frame 7, a hydraulic rod 12 is fixedly provided in the middle of one side of the support plate 18, a fixing plate 13 is fixedly provided at one end of the hydraulic rod 12 away from the support plate 18, and one end of the fixing plate 13 is fixedly provided at the top of the outer side of the left end of the inner extension plate 1.

[0028] A rectangular laying frame 3 is fixedly set on one side of the right end of the outer layer plate 2, and a lubricant storage box 4 is fixedly set on the top of the rectangular laying frame 3. A coating pipe 5 is evenly set on the bottom of the lubricant storage box 4. The bottom of the coating pipe 5 passes through the top of the rectangular laying frame 3. The bottom of the coating pipe 5 is conically set and a ball is set inside. The ball diameter at the bottom of the coating pipe 5 is larger than the diameter at the outlet. The bottom of the coating pipe 5 is located at a lower position inside the rectangular laying frame 3. When the reverse osmosis membrane is laid, it contacts the ball at the bottom of the coating pipe 5. The water-soluble lubricant inside the coating pipe 5 is evenly coated on the surface of the reverse osmosis membrane through the rotation of the ball. The bottom of the lubricant storage box 4 is set parallel to the top of the rectangular laying frame 3.

[0029] The working principle of a reverse osmosis membrane replacement tool in the embodiment of the present application is as follows: when in use, the inner extension plate 1 is dragged to slide inside the outer plate 2 according to the length of the reverse osmosis membrane frame. When it moves to the specified length, the positioning bolt 11 is rotated to release the internal thread track 14 on the side of the inner extension plate 1, and the inner extension plate 1 and the outer plate 2 are fixed as a whole through the positioning bolt 11, and the limit plate 15 is moved to a vertical state with the inner extension plate 1, and the rubber suction cup 16 on one side of the limit plate 15 is tightly adsorbed with the reverse osmosis membrane frame to achieve the effect of fixing the tool, and the hydraulic rod 12 is started as a power to drive the U The U-shaped moving frame 7 moves, and the U-shaped moving frame 7 drives the inner arc-shaped toggle plate 6 to slide on one side of the reverse osmosis membrane. Under the action of the movement of the arc-shaped toggle plate 6, the reverse osmosis membrane is pushed out of the frame to facilitate subsequent replacement. When the reverse osmosis membrane needs to be laid, one end of the reverse osmosis membrane is passed through the inside of the rectangular laying frame 3 and dragged to the outside. When the reverse osmosis membrane contacts the ball at the bottom of the coating pipe 5, the ball is forced to rotate, and the water-soluble lubricant in the lubricant storage box 4 flows out at the same time, through the coating pipes 5 evenly arranged inside the rectangular laying frame 3, so as to achieve the effect of evenly coating the water-soluble lubricant on the surface of the reverse osmosis membrane.
