[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1

[0031] Reference Figures 2 to 8 , which is the first embodiment of the utility model, provides a reverse osmosis membrane offline cleaning device, which includes an installation component 200, a limit component 300 and a main body component 100. The combination of the three can save a lot of time consumed in tightening bolts one by one, and can quickly complete the connection between the water tank and the pipeline.

[0032] The mounting assembly 200 includes a fixed bar 201a, a driving disc 201b, a movable bar 201c, a rotating rod 201d, a gear 201e and a ring gear 201f. The movable bar 201c is fixed to one side of the fixed bar 201a, the driving disc 201b is sleeved on the outside of the movable bar 201c, the driving disc 201b and the movable bar 201c are movably connected, the rotating rod 201d is fixed to one side of the driving disc 201b, the gear 201e is fixed to the top of the rotating rod 201d, the ring gear 201f is sleeved on the outside of the gear 201e, and the ring gear 201f and the gear 201e are engaged.

[0033] A driving groove is provided on the driving disk 201b, and there are six moving bars 201c, all of which slide in the driving groove. There are six fixed bars 201a, and a fixing groove corresponding to the fixing bar 201a is provided in the second fixed disk 102. The water pipe is usually fixed on the first fixed disk 101. By placing the first fixed disk 101 on the second fixed disk 102 and rotating the ring gear 201f, the rotation of the ring gear 201f can simultaneously drive the four gears 201e to rotate, and the rotation of the gear 201e drives the rotating rod 201d to rotate. The rotation of the rotating rod 201d can drive the driving disk 201b to rotate. The rotation of the driving disk 201b will cause the driving groove above to squeeze the moving bar 201c to move it, and the movement of the moving bar 201c drives the fixing bar 201a to enter the fixing groove, thereby completing the connection between the first fixed disk 101 and the second fixed disk 102, without manually tightening the bolts one by one, thereby improving efficiency.

[0034] The limiting assembly 300 is arranged on the ring gear 201f, and includes a limiting block 301a, a moving rod 301b, a driving rod 301c and a support shaft 301d. The limiting block 301a is arranged at the top of the ring gear 201f, the moving rod 301b is fixed to the top of the limiting block 301a, the driving rod 301c is hinged to the top of the moving rod 301b, and the support shaft 301d is inserted into one side of the driving rod 301c.

[0035] After the first fixed disk 101 and the second fixed disk 102 are connected, in order to prevent the ring gear 201f from being accidentally touched and rotating, it needs to be limited. At this time, the ring gear 201f can be limited by the setting of the limit block 301a to prevent the ring gear 201f from rotating on its own. When it is necessary to release the limit on the ring gear 201f, the driving rod 301c is pressed to lift one end of it. The movement of the driving rod 301c will drive the moving rod 301b to move. The movement of the moving rod 301b drives the limit block 301a to separate from the ring gear 201f, thereby releasing the limit on the ring gear 201f. The support shaft 301d is used to support the driving rod 301c to prevent the driving rod 301c from deflecting.

[0036] Example 2

[0037] Reference Figures 2 to 8 , which is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0038] Specifically, a support shell 202a is sleeved on the outer side of the fixing bar 201a, and the fixing bar 201a and the support shell 202a are movably connected.

[0039] The supporting shell 202a is used to support the fixing bar 201a to prevent the fixing bar 201a from deflecting when moving.

[0040] Specifically, a support sleeve 202b is provided on the outer side of the rotating rod 201d, and the support sleeve 202b is fixed to the top of the support shell 202a.

[0041] The support sleeve 202b is fixed to the inner wall of the first fixed plate 101, and the support sleeve 202b is movably connected to the rotating rod 201d. The setting of the support sleeve 202b can support the rotating rod 201d to prevent the rotating rod 201d from deflecting.

[0042] Specifically, a limiting groove X corresponding to the limiting block 301 a is provided on the ring gear 201 f, and the limiting block 301 a is provided in the limiting groove X.

[0043] When the ring gear 201f needs to be limited, the ring gear 201f can be limited by engaging the limiting block 301a with the limiting groove X. When the limiting block 301a is separated from the limiting groove X, the limiting of the ring gear 201f can be released.

[0044] Specifically, a support plate 302a is sleeved on the outer side of the support shaft 301d, and the support plate 302a is connected to the support shaft 301d through rotation.

[0045] The support plate 302a is fixed to the top of the first fixed plate 101. The support plate 302a can support the support shaft 301d to prevent the support shaft 301d from deflecting.

[0046] Specifically, a pressing plate 302b is fixed to one end of the driving rod 301c, and a pressing bar 302c is fixed to the top of the pressing plate 302b.

[0047] By pressing the pressing bar 302c, the pressing bar 302c drives the pressing plate 302b to move, and the movement of the pressing plate 302b can lift one end of the driving rod 301c to separate the limiting block 301a from the limiting groove X.

[0048] Specifically, a movable column 302g is fixed to the bottom of the pressing plate 302b, and a support column 302h is sleeved on the outer side of the movable column 302g. The movable column 302g and the support column 302h are movably connected.

[0049] The pressing plate 302b can drive the movable column 302g to move when moving, and the movement of the movable column 302g can support the pressing plate 302b. The supporting column 302h is used to support the movable column 302g to prevent the movable column 302g from deflecting when moving.

[0050] Example 3

[0051] Reference Figure 1 and Figure 2 , which is the third embodiment of the present utility model, and is based on the first two embodiments.

[0052] Specifically, a spring 302f is fixed to the inner wall of the support column 302h, and the spring 302f is fixed to one end of the movable column 302g. A support frame 302e is provided at the bottom of the support column 302h, and the support frame 302e is hinged to the support column 302h.

[0053] When the movable column 302g moves, it can exert an extruding force on the spring 302f. The movement of the movable column 302g can separate the limit block 301a from the limit slot X. When the pressing bar 302c is released, the rebound force of the spring 302f can re-engage the limit block 301a with the limit slot X. The support frame 302e is fixed to the top of the first fixed plate 101. The setting of the support frame 302e can support the support column 302h to prevent the support column 302h from deflecting.

[0054] Specifically, it also includes a main body component 100, which is arranged on the fixed bar 201a, including a first fixed plate 101, a second fixed plate 102, a water tank 103 and a cleaning machine 105. The first fixed plate 101 is arranged on the outside of the support sleeve 202b, the second fixed plate 102 is located at the bottom of the first fixed plate 101, the water tank 103 is fixed to one side of the second fixed plate 102, and the cleaning machine 105 is arranged on one side of the water tank 103.

[0055] A water pipe is usually provided on the first fixed disk 101. By connecting the first fixed disk 101 with the second fixed disk 102, the water tank 103 and the water pipe can be connected. External clean water is introduced into the water tank 103 through the water pipe to replenish the water consumed in the cleaning process and to prepare new cleaning liquid. Two connecting holes are also provided on one side of the water tank 103 for connecting different liquid medicine tanks. Different liquid medicine tanks are filled with different cleaning liquids, which can be used to perform targeted cleaning on different types of dirt and pollutants on the osmotic membrane.

[0056] The water tank 103 is connected to one side of the cleaning machine 105. By introducing the clean water in the water tank 103 into the cleaning machine 105, the permeable membrane placed on the cleaning machine 105 can be cleaned. The cleaning machine 105 is connected to a plurality of connecting pipes, which are connected to the permeable membrane. Through the setting of the connecting pipes, clean water can be introduced into the permeable membrane, so that the inside of the membrane can be cleaned. Before cleaning the permeable membrane, the permeable membrane needs to be blocked with a closing cover to prevent the clean water from leaking. After the cleaning is completed, the closing cover can be removed. The cleaning machine 105 can clean multiple permeable membranes at the same time. It can be connected to different liquid medicine tanks for placing different cleaning liquids so that the permeable membrane can be cleaned with different cleaning liquids. The traditional cleaning method may only be able to clean one permeable membrane at a time, while this cleaning machine 105 can process multiple permeable membranes at the same time, greatly saving time and cost.

[0057] Specifically, support legs 104 are fixed to the bottom of the water tank 103 .

[0058] The support legs 104 are used to support the water tank 103 to prevent the water tank 103 from shifting.

[0059] When in use, when it is necessary to connect one side of the water tank 103 to the water pipe, first place the first fixing plate 101 on the second fixing plate 102. At this time, the support sleeve 202b will enter the mounting hole on the second fixing plate 102, and the fixing bar 201a will move to one side of the fixing groove, first releasing the limit of the gear ring 201f, and by pressing the pressing bar 302c, the pressing bar 302c drives the pressing plate 302b to move. The movement of the pressing plate 302b can lift one end of the driving rod 301c to separate the limit block 301a from the limit groove X, and the pressing plate 302b can drive the movable column 302g to move when moving. The movement of the movable column 302g can apply an extrusion force to the spring 302f, and the movement of the movable column 302g can separate the limit block 301a from the limit groove X to release the limit on the gear ring 201f.

[0060] Then rotate the ring gear 201f. The rotation of the ring gear 201f can drive the four gears 201e to rotate at the same time. The rotation of the gear 201e drives the rotating rod 201d to rotate. The rotation of the rotating rod 201d can drive the driving plate 201b to rotate. The rotation of the driving plate 201b will cause the driving groove above to squeeze the movable bar 201c to make it move. The movement of the movable bar 201c drives the fixed bar 201a to enter the fixed groove, thereby completing the connection between the first fixed plate 101 and the second fixed plate 102. Then release the pressing bar 302c, and the rebound force of the spring 302f can make the limit block 301a re-engage with the limit groove X, so that the ring gear 201f can be limited to prevent the ring gear 201f from rotating by itself and causing the connection between the first fixed plate 101 and the second fixed plate 102 to loosen.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
