Description

Technical Field

[0001] The invention belongs to the technical field of water tower cleaning, and in particular relates to a fixing device, a fixing method and a disassembly method of a water tower cleaning system. Background Art

[0002] Water towers (or water tanks) are usually installed high up on the roof, and some are even installed on the slope of the roof. The water tank itself is high and has a smooth surface. If the cleaning staff climbs up to clean the water tank, they are likely to slip, so cleaning the water tank is an extremely dangerous thing. Every year, many people fall from heights and get injured or even die because of cleaning water tanks. After opening the top cover of the water tank, because the water tank is deep and cannot be reached by hand, tools like mops are needed, but there are many dead corners that cannot be cleaned; another problem is that the deeper the water tank, the longer the handle required, the greater the torque, and it is very difficult to clean.

[0003] Generally, water tanks are not cleaned intentionally. Most of the time, it is because there is sewage in the faucet that people check the water tank and find a lot of dirt accumulated at the bottom of the tank. If this happens during a water shortage, it is a very embarrassing choice. If the water tank is completely emptied for cleaning, it means that not a drop of water will be used, and it is very wasteful!

[0004] In order to solve the above problems, an automatic water tower cleaner is proposed in the prior invention patent application CN 110773528 A, which can better solve the problem of cleaning the water tank without water. The cleaner is installed at the bottom of the water tower through a shell, and the feed end at the upper end of the shell is screwed to the bottom of the water tower through a thread, that is, a nut is installed in advance at the installation hole at the bottom of the water tower by welding or other means, and then a thread is set on the outer periphery of the feed end of the shell, and the installation is completed by tightening the feed end to the nut. Although this method can achieve installation, it is not convenient to disassemble and assemble, and it is difficult to install the nut on the installation hole at the bottom of the water tower. For example, personnel need to enter the water tower to install it, which has certain difficulties and defects. Summary of the invention

[0047] <Example 1>

[0048] This embodiment provides a fixing device 6 for a water tower cleaning system, which is used to install a cleaning system 7 on a mounting hole 51 at the bottom of a water tower 5 to clean the water tower. Figure 1 and Figure 2 As shown, the fixing device 6 includes a fixing member 61, a pressure ring 62, a fastener 63, a locking member 64 and a sealing portion. The fixing member 61 is in the shape of a shell, and a cleaning system is installed inside. The cleaning system is installed on the mounting hole 51 at the bottom of the water tower 5 through the fixing member 61. The sealing portion is used to form a seal between the fastener 63 and the edge of the mounting hole 51, between the fastener 63 and the fixing member 61, and between the fixing member 61 and the edge of the mounting hole 51.

[0049] like Figure 3 and Figure 4As shown, the fixing member 61 has a main body portion 610 in the shape of a sleeve, and a connecting portion is provided above the main body portion 610, which is a threaded segment 611. The fastener 63 is a rotating sleeve (such as a nut) with an internal thread 631, which is connected to the outer periphery of the threaded segment 611 through the internal thread 631 and can rotate relative to the threaded segment 611. During the rotation process, the fastener 63 will move along the axial direction of the fixing member 61, so that the fastener 63 has a rotation direction and a movement direction. A snap-fit ​​portion 612 for cooperating with the mounting hole 51 is provided above the threaded segment 611. The snap-fit ​​portion 612 includes a plurality of snap-fit ​​strips 613 arranged in a ring shape, and a spacing area 614 is formed between two adjacent snap-fit ​​strips 613. One end (lower end) of the snap-fit ​​strip 613 is integrally connected to the threaded segment 611, and the other end (upper end) is provided with an insertion portion with a certain elasticity, which can be inserted into the mounting hole 51, and a hook 6131 that can be hooked on the edge of the mounting hole 51 is formed at the end of the insertion portion.

[0050] Since there is a spacer 614 between the buckle strips 613 and the inserted portion of the buckle strips 613 has a certain elasticity, the buckle portion 612 has a relaxed state in which the buckle strips 613 remain in a vertical state and a retracted state in which the buckle strips 613 are deformed. In the relaxed state, the inserted portion of the buckle strips 613 remains separated; in the retracted state, the inserted portion of the buckle strips 613 gathers inward and the upper portion of the spacer 614 shrinks. When the buckle portion 612 is in the relaxed state, the outer diameter size at the maximum outer diameter (i.e., the circular diameter where the outer edge of the hook is located) is greater than the inner diameter of the mounting hole 51; when the buckle portion 612 is in the retracted state, the outer diameter size at the maximum outer diameter is smaller than the inner diameter of the mounting hole 51, and the buckle portion 612 can be extended into the mounting hole 51 for installation.

[0051] The pressure ring 62 is sleeved on the outer periphery of the buckle portion 612 and can be used to switch the buckle portion 612 between a relaxed state and a retracted state. Figure 4 and Figure 5As shown, the pressing ring 62 has a main body 621 and an action part 622. The main body 621 is annular, sleeved outside the buckle part 612, and located at one end of the fastener 63. The action part 622 is integrally formed at one end of the main body 621 away from the fastener 63, and protrudes inward to form a plurality of inserts 623 that can be embedded in the spacer 614 when the buckle part 612 is in a relaxed state. The number of inserts 623 is equal to the number of spacers 614, and each insert 623 is correspondingly embedded in one spacer 614. The span of the spacer 614 along the circumferential direction is greater than the width of the insert 623, and an arc-shaped guide surface 6231 is provided on one side of the insert 623, and the guide surface 6231 can guide the buckle strips 613 to gather together, so that the buckle part 612 changes from a relaxed state to a retracted state; a gap is left between the other side of the insert 623 and the side of the buckle strip 613, so as to facilitate the state change of the buckle part 612.

[0052] The pressure ring 62 is installed above the fastener 63, and a first sealing ring 651 is provided between the main body 621 and the fastener 63, a second sealing ring 652 is provided between the end of the main body 621 away from the fastener 63 and the edge of the mounting hole 51, and a third sealing ring 632 is provided between the connecting portion (threaded section 611) and the fastener 63. The first sealing ring 651, the second sealing ring 652 and the third sealing ring 632 form the above-mentioned sealing portion. Figure 8 As shown, the upper and lower end surfaces of the main body 621 are respectively formed with an upper groove and a lower groove, the first sealing ring 651 is installed in the lower groove, and the second sealing ring 652 is installed in the upper groove, thereby strengthening the connection tightness and sealing between the water tower, the pressure ring 62 and the fastener 63.

[0053] When the buckle portion 612 is in a relaxed state, the insert 623 is embedded in the spacer 614. Figure 5 As shown, the guide surface 6231 is located on the side of the insert 623 facing the buckle strip 613 located on the right side. At this time, the pressure ring 62 is rotated in the clockwise direction. Under the action of the guide surface 6231, the buckle strip 613 located in the rotation direction will move along the guide surface 6231, so as to get close to the adjacent buckle strip 613 and form a retracted state. On the contrary, when the buckle portion 612 is in the retracted state, the pressure ring 62 is rotated in the opposite direction (in the counterclockwise direction). Under the action of the guide surface 6231, the insert 623 is gradually inserted into the spacer 614, so as to separate the buckle strip 613 and return to the relaxed state.

[0054] In order to ensure that the buckle portion 612 can be stably fixed on the mounting hole 51, a locking member 64 is also provided. Figure 5 As shown, the locking member 64 is disposed on the buckle portion 612, and is combined with Figure 6-Figure 8The locking member 64 has a locking portion 641 and a driving portion 642. The locking portion 641 is in a circular shape and is located on the inner side of the buckle strip 613. It contains an unlocking position for allowing the buckle portion 612 to change from a relaxed state to a retracted state and a locking position for allowing the buckle portion 612 to always remain in a relaxed state.

[0055] like Figure 8 and Fig. 9 As shown, the inner side of the buckle strip 613 has a first inclined guide surface 6132, and the upper end surface of the locking portion 641 has a second inclined guide surface 6411 that cooperates with the first inclined guide surface 6132. The inner upper side of the buckle strip 613 forms an annular action surface 6133 that protrudes inward and is used to interact with the locking portion 641, with the first inclined guide surface 6132 as the boundary. The annular action surface 6133 forms a locking space for the upper end of the locking portion 641 to be inserted. When the upper end of the locking portion 641 is inserted into the locking space, the locking portion 641 can reach the locking position. The first inclined guide surface 6132 and the second inclined guide surface 6411 can guide the movement of the locking portion 641, so that the upper end of the locking portion 641 can be more easily inserted into the locking space.

[0056] When the locking portion 641 is in the unlocked position, Figure 7 As shown, at this time, since the locking portion 641 is separated from the buckle strip 613, the buckle strip 613 is easily driven by the pressure ring 62 to form an inwardly contracted state and is removed from or installed in the mounting hole 51; when the locking portion 641 is in the locked position, as shown in FIG. Figure 8 As shown, at this time, since the projections of the locking portion 641 and the annular action surface 6133 on the circumferential surface have an overlapping portion or the locking portion 641 is tightly attached to the inner wall of the annular action surface 6133, under the obstruction of the locking portion 641, the buckle strip 613 cannot be deformed to form an inwardly retracted state under the drive of the pressure ring 62, so that the buckle portion 612 can always remain in a relaxed state, so that the buckle portion 621 can always be stably stuck on the edge of the mounting hole 51, thereby enhancing the firmness of the installation.

[0057] like Figure 6 and Figure 8 As shown, a plurality of driving parts 642 are spaced apart on the outer circumference of the locking part 641. The driving part 642 is used to cooperate with the fastener 63. The fastener 63 contacts the bottom of the driving part 642 during the rotation process and pushes the locking part 641 upward from the unlocking position to the locking position. There is a partition 643 between adjacent driving blocks 642 for the buckle strip 613 to pass through, as shown in FIG. Fig. 9As shown, the number of driving parts 642 corresponds to the number of spacers 614; the number of buckle strips 613 corresponds to the number of partitions 643. During installation, the driving parts 642 extend into the spacers 614 between the buckle strips 613, the buckle strips 613 are located in the partitions 643, and the bottom of the driving parts 642 extends out of the spacers 614 and is placed on the top of the fastener 63. Figure 8 As shown, since the fastener 63 is located at the periphery of the buckle portion 612, in order to allow the bottom of the driving portion 642 to normally contact the fastener 63, the main body 621 of the pressure ring 62 is located on the side of the action portion 622 facing the fastener 63 and is provided with an inwardly contracted annular embedding groove 624 (also referred to as an avoidance groove), and the outer end of the driving block 642 passes through the spacer 614 and is embedded in the annular embedding groove 624. The annular embedding groove 624 is provided below the action portion 622 to limit the moving stroke of the driving block 642. Since one end (upper end) of the spacer 614 is open, the other end (lower end) has a stop edge 6141 for blocking the driving block 642, and the stop edge 6141 forms a lower limit for the bottom of the driving block 642. Since the action part 622 is formed with an insert 623 that can be inserted into the spacer 614, the insert 623 can form an upper limit position for the driving block 642. When the buckle part 612 is in a relaxed state, the locking member 64 can be prevented from falling off under the obstruction of the insert 623; at the same time, the locking part 641 can be pushed to return from the locked position to the unlocked position. In addition, the length of the threaded section 611 matched with the fastener 63 in the longitudinal direction is greater than or equal to the travel length of the locking part 641 from the unlocked position to the locked position, so as to ensure that the locking part 641 can normally switch between the unlocked position and the locked position.

[0058] In this embodiment, the driving part 642 is a fan-shaped block structure, and the middle part is hollowed out, which can reduce the weight of the driving part and save materials. In actual situations, it can also be other shapes or solid structures. Since the fastener 63 has a rotation direction and a movement direction relative to the connection part (i.e., the threaded section 611) of the fixing member 61, the setting of the driving block 642 only needs to satisfy the overlap of the projections of the pressing ring 62, the driving block 642 and the fastener 63 in the movement direction. In this way, it can ensure that the driving block 642 can move from the unlocking position to the locking position under the action of the fastener 63, and it can also ensure that the driving block 642 does not fall off under the obstruction of the pressing ring 62, and at the same time, the driving block 642 can move from the locking position to the unlocking position under the drive of the pressing ring 62.

[0059] The top of the insertion portion of the buckle strip 613 has a hook 6131 that can be hooked on the edge of the mounting hole 51 , and a third inclined guide surface 6134 is provided on the outer side of the hook 6131 to facilitate guidance when installed in the mounting hole 51 .

[0060] In this embodiment, since the fixing device 6 is used to install the cleaning system 7 on the water tower, in order to install the cleaning system 7, the fixing member 61, the pressure ring 62 and the locking member 64 need to be hollow, that is, the locking portion 641 is annular, and the middle part can be passed through by the cleaning system 7. In actual situations, the fixing device 6 can also be used in other scenarios where two components need to be fixed. In this case, if there is no need to pass the locking portion 641 through the component for installation, the locking portion 641 can also be set to a solid cylindrical shape.

[0061] The fixing method of the fixing device of this embodiment comprises the following steps:

[0062] S1: Check the buckle portion 612 to make the buckle strip 613 on the buckle portion 612 in a relaxed state. At this time, the locking portion 641 is separated from the locking area inside the buckle strip 613. Fig.10 Status shown;

[0063] S2: The pressing ring 62 is rotated clockwise, and the buckle strip 613 is contracted under the action of the pressing ring 62, so that the buckle portion 612 is transformed into a retracted state, such as Fig.11 In the state shown, after tightening, insert it into the mounting hole 51 from bottom to top;

[0064] S3: After confirming that the buckle portion 612 enters the mounting hole 51, the pressing ring 62 is released, and the buckle portion 612 gradually returns to the relaxed state and is hooked on the inner side of the edge of the mounting hole 51. Fig.12 Status shown;

[0065] S4: Rotate the fastener 63, and the fastener 63 moves upward with the pressure ring 62 and the locking member 64, so that the locking member 64 moves from the unlocking position to the locking position, and the installation and fixation are completed. At this time, the upper end of the locking portion 641 has extended into the locking area inside the buckle strip 613, and the pressure ring 62 is tightly pressed between the fastener 63 and the bottom of the water tower, as shown in FIG. Fig.13 Status shown.

[0066] The disassembly method of the fixing device of this embodiment comprises the following steps:

[0067] N1: Rotate the tightening member 63 to loosen it;

[0068] N2: Press the pressing ring 62 downward to drive the locking member 64 downward, so that the locking member 64 moves downward from the locking position to the unlocking position;

[0069] N3: Move up and rotate the pressing ring 62 or directly rotate the pressing ring 62 to change the buckle portion 612 from a relaxed state to a retracted state and then tighten it and pull it out from top to bottom. The buckle portion 612 is separated from the mounting hole 51, and the disassembly is completed.

[0070] The fixing device 6, fixing method and disassembly method of the water tower cleaning system provided by the present invention are as follows. Since a buckle portion 612 is provided on the fixing member 61, and a pressure ring 62 is provided on the outer side of the buckle portion 612, during installation, it is only necessary to rotate the pressure ring 62, and the pressure ring 62 will drive the buckle portion 612 to tighten and form an inwardly contracted state, and then it can be directly inserted into the mounting hole 51 on the water tower 5, and then the pressure ring 62 is rotated in the opposite direction to allow the buckle portion 612 to return from the inwardly contracted state to the relaxed state, at which time the buckle portion 612 can be clamped in the mounting hole 51 to complete the installation; conversely, during disassembly, it is only necessary to rotate the pressure ring 62 to drive the buckle portion 612 to tighten and form an inwardly contracted state, and then directly pull it out from the mounting hole 51 to complete the disassembly. During installation, the staff can directly disassemble and assemble the fixing device outside the water tower without entering the inside of the water tower. The disassembly and assembly is very convenient and labor-saving, and the water tower only needs to open a hole, and there is no need to install nuts inside the water tower, which reduces the technical requirements.

During installation, the buckle portion 612 on the fixing member 61 is directly tightened by hand to form an inwardly retracted state, and then inserted into the mounting hole 51 from bottom to top. After releasing the hand, the buckle portion 612 is allowed to return to a relaxed state, and then the fastener 63 is rotated until the sealing gasket on the top of the fastener 63 is tightly attached to the outer surface of the mounting hole 51 to complete the installation.

[0073] <Example 3>

[0074] In this embodiment, a locking member 64 as in embodiment 1 is provided on the basis of the above-mentioned embodiment 2 (that is, the pressure ring is eliminated on the basis of embodiment 1). The structure of the locking member 64 is the same as that of embodiment 1. At this time, the sealing portion includes a sealing gasket arranged on the top surface of the driving portion 642 of the locking member 64 and a third sealing ring 632 pressed between the fastener 63 and the fixing member 61. During installation, the buckle portion 612 on the fixing member 61 is directly tightened by hand to form an inwardly contracted state, and then inserted into the mounting hole 51 from bottom to top. After releasing the hand, the buckle portion 612 is allowed to return to a relaxed state, and then the fastener 63 is rotated. The locking member 64 is pushed up to a locked state by the fastener 63 until the sealing gasket on the top surface of the driving portion 642 is tightly attached to the outer surface of the mounting hole 51 to complete the installation.

[0075] The above embodiments are only preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made according to the structure, shape, and principle of the present invention should be included in the protection scope of the present invention. For example, in the above embodiments, the installation of the cleaning device at the bottom of the water tower is described as an example. In actual situations, it can also be used for the installation of other objects, especially when installing a certain object into a hole of another object. In addition, in the above embodiments, the installation direction of the fixing device is from bottom to top, and the disassembly direction is from top to bottom. This is because the above embodiments are aimed at the situation of installation at the bottom. In actual situations, the installation direction can be adaptively adjusted according to the actual installation position. For example, assuming that the mounting hole is located at the top, the buckle portion 612 needs to be facing downward and installed on the mounting hole from top to bottom.
