[0038] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 , an embodiment of the present invention provides an inverted reverse osmosis membrane column fastening tool, comprising an electromagnetic adsorption mechanism 1 and an intermediate transmission mechanism 2;

[0039] The electromagnetic adsorption mechanism 1 includes a fastening sleeve 3, an adsorption sleeve 4 and an electromagnet 5; the fastening sleeve 3 is located at the center of the adsorption sleeve 4, and a fastening matching cavity 6 is formed at the center of the fastening sleeve 3; a limiting flange 7 is formed at the edge of the adsorption sleeve 4, and the electromagnet 5 is sleeved on the periphery of the adsorption sleeve 4, and the electromagnet 5 is located below the limiting flange 7;

[0040] The intermediate transmission mechanism 2 includes a transmission base 8, a first transmission shaft 9, a first bevel gear 10, a second transmission shaft 11 and a second bevel gear 12; a fastening fitting joint 13 is formed at the upper end of the first transmission shaft 9, the fastening fitting joint 13 is located above the transmission base 8, the lower end of the first transmission shaft 9 is located inside the transmission base 8, and the first bevel gear 10 is connected to the lower end of the first transmission shaft 9; one end of the second transmission shaft 11 is located inside the transmission base 8, the second bevel gear 12 is connected to the second transmission shaft 11, and the second bevel gear 12 is meshed with the first bevel gear 10;

[0041] The electromagnetic adsorption mechanism 1 is connected to the fastening fitting joint 13 of the intermediate transmission mechanism 2 via the fastening fitting cavity 6 .

[0042] In this embodiment, an adjustment mechanism 14 is also included, which includes a slide 15, an adjustment bracket 16 and an adjustment rod 17; a sliding groove 18 is formed at the bottom of the transmission base 8, and a sliding guide rail 19 is formed at the top of the slide 15, and the sliding guide rail 19 is located in the sliding groove 18; a sliding avoidance hole 20 is formed at the center of the slide 15, and the upper end of the adjustment bracket 16 is connected to the transmission base 8 through the sliding avoidance hole 20; an ear seat 21 is provided at the lower end of the slide 15, and an adjustment support 22 is connected to the side of the adjustment bracket 16, and a through hole 23 is formed at one end of the adjustment rod 17, and the adjustment bracket 16 passes through the through hole 23, and one end of the adjustment rod 17 with the through hole 23 is hinged to the ear seat 21; the adjustment rod 17 is hinged to the adjustment support 22 at a position below the through hole 23, and the other end of the adjustment rod 17 extends to the outside of the adjustment bracket 16.

[0043] Among them, the slide 15, adjustment bracket 16 and adjustment rod 17 of the adjustment mechanism 14 utilize the lever principle to achieve effective support for the fastening tool and the lower pipeline or platform. When the electromagnet 5 outside the adsorption sleeve 4 is powered off, the adjustment mechanism 14 can quickly approach the end cover of the inverted membrane column to assist in constraining the vertical (along the direction of the adjustment bracket 16) movement freedom in the working state.

[0044] Specifically, the adjusting rod 17 itself is relatively long and can extend to the outside of the reverse osmosis device where the membrane column is installed. By operating the adjusting rod 17, since a through hole 23 is provided at the center of the adjusting rod 17, the adjusting rod 17 drives the slide 15 through the adjusting support 22 and the ear seat 21, and the slide 15 moves in the sliding slot 18 of the transmission base 8 through the sliding guide rail 19.

[0045] The design of the through hole 23 avoids the interference between the adjustment bracket 16 and the adjustment rod 17, and the design of the sliding avoidance hole 20 can avoid the interference between the slide 15 and the adjustment bracket 16 during the sliding process of the slide 15 along the transmission base 8. When the outer end of the adjustment rod 17 applies force, the adjustment rod 17 can apply an upward force to the slide 15 along the adjustment bracket 16.

[0046] In this embodiment, an arc-shaped tightening plate 24 is formed at the bottom of the adjusting bracket 16. Figure 4 The adjusting bracket 16 can be fixed on the matching pipeline at the bottom through the arc-shaped top tightening plate 24.

[0047] In this embodiment, the upper width of the sliding slot 18 is greater than the lower width of the sliding slot 18; the upper width of the sliding guide rail 19 is greater than the lower width of the sliding guide rail 19; the inner wall of the sliding slot 18 and the outer wall of the sliding guide rail 19 are consistent. Since the slide 15 and the transmission base 8 are in a vertical relationship, the sliding slot 18 and the sliding guide rail 19 are both designed to be wide at the top and narrow at the bottom, so that the slide 15 can be suspended below the transmission base 8. In the assembly process of the sliding guide rail 19 and the sliding slot 18, the sliding guide rail 19 slides into the sliding slot 18 from one side.

[0048] In this embodiment, a rolling bearing 25 is provided in the gap between the fastening sleeve 3 and the adsorption sleeve 4, and the fastening sleeve 3 passes through the center of the rolling bearing 25; a molded hole 26 matching the model of the membrane column is formed inside the fastening sleeve 3.

[0049] Specifically, the fastening sleeve 3 and the adsorption sleeve 4 are installed concentrically, and the upper end of the fastening sleeve 3 is lower than the upper end of the adsorption sleeve 4 to avoid friction with the end cover during fastening. A rolling bearing 25 is installed between the fastening sleeve 3 and the adsorption sleeve 4 to achieve relative rotation of the fastening sleeve 3 and the adsorption sleeve 4, that is, the adsorption sleeve 4 is fixed and the fastening sleeve 3 can also rotate freely.

[0050] Among them, the upper end of the fastening sleeve 3 is opened with a hexagonal hole to match the membrane column model, the lower end of the fastening sleeve 3 is opened with an inner square hole to match the first transmission shaft 9, and the lower half is radially opened with a hole to be connected and fixed with the vertically arranged first transmission shaft 9.

[0051] In this embodiment, a limiting ring 27 is provided on the outer wall of the adsorption sleeve 4, and the electromagnet 5 is located between the limiting ring 27 and the limiting flange 7. The second transmission shaft 11 is connected to a fixing block 28, and a clamping plate 29 is connected to one side of the fixing block 28 close to the transmission base 8, and a fixing clamping groove 30 is formed on the top of the clamping plate 29. The electromagnet 5 is connected to an electromagnetic controller 31 through a wire, and the electromagnetic controller 31 is arranged on the outer side of the clamping plate 29.

[0052] Specifically, the limit ring 27 and the limit flange 7 play the role of installation limit of the electromagnet 5. The adsorption and separation between the adsorption sleeve 4 and the membrane column end cover are changed through the electromagnetic controller 31, and the gravity of the tool is overcome by the electromagnetic force, thereby reducing the labor intensity of the workers and avoiding the problem of inaccurate adsorption position of the permanent magnetic material and difficulty in separating from the adsorption matrix.

[0053] The design of the clamping plate 29 and the fixing slot 30 can realize the fixing of the fastening tool and the membrane column support at the edge of the reverse osmosis device. The fixing block 28 plays the role of fixing the clamping plate 29. The combined fixing block 28 and the clamping plate 29 can slide relative to the second transmission shaft 11, so that the position of the fixing slot 30 can be changed as needed to fasten the membrane columns at different distances from the membrane column support at the edge of the reverse osmosis device.

[0054] The electromagnetic controller 31 is installed outside the card plate 29, at the user's operating end, to facilitate the control of the electromagnet 5. The control principle of the electromagnetic controller 31 on the electromagnet 5 has related technologies, which will not be repeated here.

[0055] In this embodiment, a first bearing 32 is provided at the contact position between the transmission base 8 and the first transmission shaft 9 , and a second bearing 33 is provided at the contact position between the transmission base 8 and the second transmission shaft 11 ; the first bearing 32 and the second bearing 33 are both fixedly connected to the transmission base 8 .

[0056] Specifically, the first transmission shaft 9 can rotate relative to the transmission base 8 through the first bearing 32, and the second transmission shaft 11 can rotate relative to the transmission base 8 through the second bearing 33. When force is applied to the outer end of the second transmission shaft 11 to rotate the second transmission shaft 11, the second transmission shaft 11 rotates the first bevel gear 10 through the second bevel gear 12, and the rotation of the first bevel gear 10 rotates the first transmission shaft 9. The rotation of the first transmission shaft 9 realizes the rotation of the fastening sleeve 3 through the fastening fitting joint 13, thereby realizing the fastening effect on the membrane column.

[0057] Assistance Figure 4 and Figure 5 Through the technical solution of the present invention, during the actual installation process, the electromagnet 5 is first powered off, the fastening tool is placed at the bottom of the inverted membrane column, the adjustment bracket 16 is inserted into the bottom water inlet high-pressure pipe or platform, and then the position is adjusted to align with the membrane column to be fastened, and the adjustment rod 17 is operated to make the adsorption sleeve 4 and the first transmission shaft 9 quickly approach the fastening nut of the membrane column through the electromagnet 5 and align according to the limit, thereby limiting the rotational freedom of the adsorption sleeve 4 and pre-limiting the vertical movement freedom.

[0058] Then, operate the electromagnetic controller 31, turn on the power, energize the electromagnet 5, adsorb the adsorption sleeve 4 to the end cover of the membrane column, and at the same time, the fastening nut enters the fastening sleeve 3 to limit the horizontal, longitudinal and vertical (can be defined as X, Y, Z) movement freedom of the adsorption sleeve 4. Adjust the card plate 29, and insert the fixed card slot 30 of the card plate 29 into the membrane column bracket to limit the longitudinal rotation freedom of the adsorption sleeve 4. During the fastening process, insert the torque wrench into the right end hole of the second transmission shaft 11 and clamp it. The torque is transmitted to the second bevel gear 12 through the second transmission shaft 11, and then changes direction and is transmitted to the first transmission shaft 9 through the second bevel gear 12 and the first bevel gear 10. It acts on the fastening nut of the inverted membrane column through the fastening sleeve 3 connected to the first transmission shaft 9. During the fastening process, the fastening tool is completely fixed on the membrane column bracket, and the bracket 16 is adjusted for auxiliary support. The adsorption sleeve 4 is adsorbed on the end cover of the membrane column and remains stationary. The fastening sleeve 3 can achieve free rotation through the internal rolling bearing 25, thereby achieving fastening.

[0059] In summary, the present invention is provided with an electromagnetic adsorption mechanism 1 and an intermediate transmission mechanism 2; the electromagnetic adsorption mechanism 1 includes a fastening sleeve 3, an adsorption sleeve 4 and an electromagnet 5; the fastening sleeve 3 is located at the center of the adsorption sleeve 4, and a fastening matching cavity 6 is formed at the center of the fastening sleeve 3; a limiting flange 7 is formed on the edge of the adsorption sleeve 4, and the electromagnet 5 is sleeved on the periphery of the adsorption sleeve 4, and the electromagnet 5 is located below the limiting flange 7; the intermediate transmission mechanism 2 includes a transmission base 8, a first transmission shaft 9, a first bevel gear 10, a second transmission shaft 11 and a second Bevel gear 12; a fastening fitting joint 13 is formed at the upper end of the first transmission shaft 9, the fastening fitting joint 13 is located above the transmission base 8, the lower end of the first transmission shaft 9 is located inside the transmission base 8, and the first bevel gear 10 is connected to the lower end of the first transmission shaft 9; one end of the second transmission shaft 11 is located inside the transmission base 8, the second bevel gear 12 is connected to the second transmission shaft 11, and the second bevel gear 12 is meshed with the first bevel gear 10; the electromagnetic adsorption mechanism 1 is connected to the fastening fitting joint 13 of the intermediate transmission mechanism 2 through the fastening fitting cavity 6. The slide 15, the adjustment bracket 16, and the adjustment rod 17 of the adjustment mechanism 14 use the principle of levers to achieve effective support of the fastening tool and the lower pipeline or platform. When the electromagnet 5 outside the adsorption sleeve 4 is powered off, the adjustment mechanism 14 can quickly approach the end cap of the inverted membrane column, and assist in constraining the vertical (along the direction of the adjustment bracket 16) degree of freedom of movement in the working state. The adjusting rod 17 itself is relatively long and can extend to the outside of the reverse osmosis device where the membrane column is installed. By operating the adjusting rod 17, since a through hole 23 is provided in the center of the adjusting rod 17, the adjusting rod 17 drives the slide 15 through the adjusting support 22 and the ear seat 21, and the slide 15 moves in the sliding slot 18 of the transmission base 8 through the sliding guide rail 19. The design of the through hole 23 avoids the interference of the movement between the adjustment bracket 16 and the adjusting rod 17, and the design of the sliding avoidance hole 20 can avoid the interference of the movement between the slide 15 and the adjustment bracket 16 during the sliding process of the slide 15 along the transmission base 8. And when the outer end of the adjusting rod 17 applies force, the adjusting rod 17 can apply an upward force along the adjustment bracket 16 to the slide 15. The fastening sleeve 3 and the adsorption sleeve 4 are installed concentrically, and the upper end of the fastening sleeve 3 is lower than the upper end of the adsorption sleeve 4 to avoid friction with the end cover during fastening. A rolling bearing 25 is installed between the fastening sleeve 3 and the adsorption sleeve 4 to achieve relative rotation of the fastening sleeve 3 and the adsorption sleeve 4, that is, the adsorption sleeve 4 is fixed and the fastening sleeve 3 can also rotate freely. The upper end of the fastening sleeve 3 is opened with an inner hexagonal hole to match the membrane column model, and the lower end of the fastening sleeve 3 is opened with an inner square hole to match the first transmission shaft 9. The lower half has a radial overhead hole to connect and fix with the vertically arranged first transmission shaft 9. The design of the clamping plate 29 and the fixing slot 30 can achieve the fixation of the fastening tool and the edge membrane column bracket of the reverse osmosis device.The fixing block 28 plays the role of fixing the card plate 29. The combined fixing block 28 and the card plate 29 can slide relative to the second transmission shaft 11, so that the position of the fixing card slot 30 can be changed as needed to fasten the membrane columns at different distances from the edge membrane column support of the reverse osmosis device. The first transmission shaft 9 can rotate relative to the transmission base 8 through the first bearing 32, and the second transmission shaft 11 can rotate relative to the transmission base 8 through the second bearing 33. When a force is applied to the outer end of the second transmission shaft 11 to rotate the second transmission shaft 11, the second transmission shaft 11 rotates the first bevel gear 10 through the second bevel gear 12, and the rotation of the first bevel gear 10 rotates the first transmission shaft 9. The rotation of the first transmission shaft 9 realizes the rotation of the fastening sleeve 3 through the fastening fitting joint 13, thereby realizing the fastening of the membrane column. The present invention can change the direction of applied force, allowing installers to more conveniently fasten the inverted membrane column, avoiding the problem that the membrane column fastening fails to reach the specified torque or is inconvenient for installers to operate due to the tool being too heavy, the bottom space being too small, or the force arm being too long, thereby improving installation efficiency and ensuring the continuous and stable operation of the entire reverse osmosis membrane device.
