Description

Technical Field

[0001] The utility model belongs to the technical field of water tower cleaning, in particular to a driving device of a water tower cleaning system. Background Art

[0002] Water tanks (or water towers) are typically located high on rooftops, sometimes even on a slope. Furthermore, the tanks themselves are tall and slippery, making cleaning a dangerous endeavor. Every year, many people are injured or even killed by falls from heights while cleaning water tanks. Once the tank lid is removed, the depth of the tank is too deep to reach by hand, requiring tools like mops. However, these tools often leave many corners unreachable. Furthermore, the deeper the tank, the longer the handle and the greater the torque required, making cleaning extremely difficult.

[0003] Generally, water tanks are not cleaned intentionally. Most of the time, people check the water tanks because there is sewage in the faucet and find that there is 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] To address the above-mentioned problems, the applicant's prior invention patent application CN 110773528 A proposed an automatic water tower cleaner. Its primary cleaning method is as follows: Opening the drain outlet allows water, carrying scraped scale and impurities, to flow directly from the cleaning pipe toward the impeller, driving the impeller to rotate. During the impeller's rotation, the cleaning pipe is driven to perform a circular motion via a rotating shaft and a rotating seat. During this circular motion, the cleaning pipe scrapes scale from the bottom surface of the water tower and then absorbs it into the water flow. The absorbed water, as it passes through the impeller, drives the impeller to rotate, thereby performing cleaning. In other words, the rotation of the cleaner is primarily driven by the water flow in the cleaning pipe rushing toward the impeller, causing it to rotate. However, in actual use, the impeller is mounted directly at the bottom of the cleaning pipe, causing the water flow to directly strike the top surface of the impeller. This results in the water flow being easily dispersed and insufficiently concentrated, resulting in a less-than-ideal impeller drive effect. Summary of the Invention

[0037] The present invention will be further described below in conjunction with specific embodiments:

[0038] Example 1:

[0039] This embodiment provides a driving device for a water tower cleaning system, in particular, a cleaning system installed on the mounting hole 51 at the bottom of the water tower 5, mainly used to clean impurities such as scale on the inner wall of the bottom of the water tower 5. Figure 1 and Figure 2 As shown, the cleaning device 100 of the water tower cleaning system is installed at the bottom of the water tower 5 through the driving device of this embodiment. The driving device mainly includes a driving mechanism 200 and a fixing mechanism 300. The cleaning device 100 includes a cleaning pipe, which includes a cleaning hose 40 and a connecting pipe 70. One end of the connecting pipe 70 is connected to the cleaning hose 40, and the other end is installed on the driving mechanism 200. The driving mechanism 200 is installed inside the fixing mechanism 300 and has an input driving part 84. The input driving part 84 is connected to the connecting pipe 70 and is used to drive the cleaning pipe to rotate, thereby cleaning the bottom of the water tower 5. The fixing mechanism 300 is used to fix the cleaning device 100 and the driving mechanism 200 on the water tower 5.

[0040] <Drive Mechanism>

[0041] The driving mechanism 200 is an impeller driving mechanism, such as Figure 2As shown, the impeller drive mechanism includes: an impeller 81, a fixing member 82, an input drive unit 84, an output drive unit 85, and a water diversion unit 86. The impeller 81, the input drive unit 84, the output drive unit 85, and the water diversion unit 86 are all mounted within the fixing member 82. The fixing member 82 has a first mounting cavity 821 for mounting the input drive unit 84 and a second mounting cavity 825 for mounting the impeller 81 and the output drive unit 85. The impeller 81 is provided with a drive shaft 83, which can extend into the first mounting cavity 821 and cooperate with the input drive unit 84.

[0042] like Figure 3 As shown, the input drive portion 84 has a drive cap 841 and an elastic member 842 (such as a spring). The drive cap 841 is movably disposed in the first mounting cavity 821 and has a working state combined with the drive shaft 83 (such as Figure 4 The state shown) and the non-working state separated from the drive shaft 83 (as shown Figure 3 In the state shown), the elastic member 842 is installed in the first mounting cavity 821, and is used to act on the drive cap 841 to keep the drive cap 841 in the non-working state. In the working state, the drive shaft 83 is combined with the drive cap 841, and the rotation of the drive cap 841 can drive the drive shaft 83 to rotate, thereby driving the impeller 81 to rotate. In the non-working state, the drive shaft 83 and the drive cap 841 are separated, and the two do not affect each other. The user can use a tool to push the drive cap 841 toward the side where the drive shaft 83 is located, thereby causing the drive cap 841 to approach and combine with the drive shaft 83, and then drive the drive cap 841 to rotate. That is, the user can use a tool to change the drive cap 841 from the non-working state to the working state. After the tool is removed, the drive cap 841 can be restored from the working state to the non-working state under the drive of the elastic member 842.

[0043] like Figure 2 、 Figure 3-Figure 4 As shown, the fixing member 82 comprises a sleeve body 822, a fixing seat 823, and a fixing cover 826. The fixing seat 823 is fixed to one end of the sleeve body 822, with a sealing ring pressed between the two. The sleeve body 822 is hollow inside, forming a receiving chamber 824 that can accommodate the output drive unit 85 and the water diversion unit 86. A second mounting chamber 825 is defined in the middle of the fixing seat 823 on the side facing the receiving chamber 824, and the impeller 81 is at least partially mounted in the second mounting chamber 825. A first mounting chamber 821 is defined in the middle of the fixing seat 823 on the side facing away from the receiving chamber 824, and the fixing cover 826 is mounted on the fixing seat 823 on the side where the first mounting chamber 821 is located. The fixing seat 823 also has a partition 827 in the middle for separating the second mounting chamber 825 from the first mounting chamber 821. The partition 827 has a through hole in the middle for the drive shaft 81 to pass through.

[0044] The fixing cover 826 is threadedly connected to the bottom of the fixing seat 823, and a fixing sleeve 8261 is formed in the middle of the fixing cover 826, which can be inserted into the fixing seat 823. The fixing sleeve 8261 is hollowed to form a first installation cavity 821, and the elastic member 842 and the driving cap 841 are installed in the fixing sleeve. The driving cap 841 has an active end 8411 and a driving end 8412 for connecting with the driving shaft 83. The fixing cover 826 is opened (such as Figure 4 A through-hole 8262 is provided (in the middle of the bottom surface shown) through which the end face of the active end 8411 is exposed. A socket 8413 is provided on the driving end 8412 for inserting the driving shaft 83. The socket 8413 has a shape that matches the driving shaft 83. A sealing gasket 843 is installed near the through-hole 8262 of the active end 8411. The side of the sealing gasket 843 facing the through-hole 8262 is used to seal against the inner edge of the through-hole 8262. A cross-shaped or straight-shaped notch is provided on the end face of the active end 8411 to facilitate the user to insert a tool (such as a cross-shaped or straight-shaped screwdriver) and then push the driving cap 841 to move and rotate it.

[0045] The input drive unit 84 and the output drive unit 85 are respectively placed on the front and back sides of the impeller 81. The output drive unit 85 is a planetary gear set installed in the accommodating cavity 824. The end of the drive shaft 83 away from the input drive unit 84 is inserted into the output drive unit 85 and combined with the output drive unit 85. Figure 2 As shown, a water inlet portion 86 is installed in the accommodating cavity 824 of the sleeve body 822 of the fixing member 82, and the water inlet portion 86 is provided with a water inlet channel 861 leading to the impeller 81. A water outlet pipe 828 is also provided on the fixing seat 823 of the fixing member 82, and a water outlet channel 8281 leading to the second installation cavity 825 is provided in the water outlet pipe 828. The water from the water inlet channel 861 flows to the impeller 81 and drives the impeller 81 to rotate, and is finally discharged from the water outlet channel 8281. During the rotation of the impeller 81, the output drive portion 85 is driven to rotate through the output shaft 83.

[0046] like Figure 2 and Figure 4 As shown, the water diversion portion 86 has a mounting sleeve 862 and a water diversion plate 863. The water diversion plate 963 is spirally arranged on the outer periphery of the mounting sleeve 862 to form a spiral water diversion channel 861. Figure 5 The spiral water channel 861 concentrates the water flow well, and the water guide plate 963 is located at the end of the water channel 861 and is inclined toward the blade interval of the impeller 81, thereby better guiding the water flow into the blade interval of the impeller 81 to push the blades to rotate the impeller 81. Figure 2As shown, the interior of the mounting sleeve 862 is hollow, and sealing members are provided at both ends in the extension direction. A sealing cavity 8621 for mounting the output drive unit 85 is formed between the two sealing members. The output drive unit 85 is mounted in the sealing cavity 8621 to form a sealed protection, which can prevent water from entering the sealing cavity and affecting the output drive unit 85.

[0047] like Figure 2 As shown, one end of the connecting pipe 70 extending into the fixing member 82 is combined with the output drive portion 85 in the fixing member 82, and a water inlet channel 73 is opened in the connecting pipe 70 to communicate with the water inlet channel 861 of the water inlet portion 86 in the fixing member 82, as shown in FIG. Figure 5 As shown, one end of the mounting sleeve 862 is formed with a mounting seat 8625 for mounting the connecting pipe 70, and the mounting seat 8625 is provided with a water hole 8622 connecting the water inlet channel 73 and the water diversion channel 861. Figure 2 and Figure 5 As shown, a fixing groove 8623 is provided in the middle of the mounting seat 8625, a bearing 8624 is fixedly installed in the fixing groove 8623, a sealing ring is provided between the bearing 8624 and the fixing groove 8623, and a connecting rod 74 is vertically provided in the middle of the connecting pipe 70, the end of the connecting rod 74 passes through the bearing 8624 and is inserted into the output end of the output drive part 85 for fixation, thereby realizing the installation and fixation of the connecting pipe 71 and the output drive part 85.

[0048] The driving principle of the cleaning pipe of this embodiment is as follows: the water flow from the cleaning hose 40 passes through the water inlet channel 73 and through the water hole 8622 to flow into the water diversion channel 861, and then flows along the water diversion plate 863 to the impeller 81, pushing the impeller 81 to rotate, and then drives the output drive part 85 to rotate through the output shaft. During the rotation process of the output drive part 85, the connecting pipe 70, the cleaning hose 40 and the support frame 10 will be rotated together, thereby cleaning the bottom of the water tower.

[0049] The recovery principle of the impeller 81 in this embodiment is as follows: when the impeller 81 is stuck due to impurities during operation, the driving cap 841 can be manually pushed using a tool (such as a screwdriver) to move the driving cap 841 toward the driving shaft 83 and engage with the driving shaft 83. Then, manual force is applied to rotate the driving cap 841. The driving cap 841 can drive the impeller 81 to rotate again through the driving shaft 83, so that the scale impurities stuck around the impeller 81 are shaken off, thereby releasing the stuck condition and allowing the impeller 81 to resume normal operation. Finally, the tool is pulled out, and the driving cap 841 returns to the non-operating state under the drive of the elastic member 842. After the tool is pulled out, the impeller 81 can still continue to operate under the drive of the water flow.

[0050] In this embodiment, the impeller 81 can be a rubber impeller with a drive shaft 83 mounted in the middle. The output drive unit 85 is a planetary gear set having an input gear. One end of the drive shaft 83 is connected to the input gear, and the planetary gear set is driven by the drive shaft 83 to rotate. Because one end of the drive shaft 83 is directly connected to the output drive unit 85, if the output drive unit 85 (planetary gear set) becomes stuck, the bottom drive cap 841 can be directly pushed into the drive shaft 83 with a screwdriver. Then, rotating the screwdriver instead of the rubber impeller 81 can drive the bottom of the planetary gear set to resume rotation, which is very convenient.

[0051] This embodiment can also realize manual driving of the cleaning tube for rotational cleaning, specifically as follows: manually use a tool (such as a screwdriver) to push the driving cap 841, so that the driving cap 841 moves toward the driving shaft 83 and engages with the driving shaft 83, and then manually apply force to rotate the driving cap 841. The driving cap 841 can drive the impeller 81 and the output drive part 85 to rotate through the driving shaft 83, thereby driving the connecting tube 71 and the cleaning hose 40 to rotate together. In this way, the cleaning tube can be manually driven to rotate and clean by continuous manual force. After cleaning is completed, the tool can be pulled out.

[0052] <Fixed mechanism>

[0053] The fixing mechanism 300 includes a pressure ring 62, a fastener 63, a locking member 64 and a sealing portion. The fixing member 82 is in the shape of a shell, and the driving mechanism 200 is installed inside. The driving mechanism 200 is installed on the mounting hole 51 at the bottom of the water tower 5 through the fixing member 82. 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 82, and between the fixing member 82 and the edge of the mounting hole 51.

[0054] The fixing member 82 has a sleeve body 822 in a sleeve shape, such as Figure 8 and Figure 9As shown, a connecting portion is provided above the sleeve body 822, which is a threaded segment 611. The fastener 63 is a rotating sleeve (such as a nut) with an internal thread 631. It 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 82, 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 spacer 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. The insertion portion 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, 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.

[0055] Because there are spacers 614 between the snap bars 613 and the inserted portions of the snap bars 613 have a certain degree of elasticity, the snap portion 612 has a number of states: a relaxed state in which the snap bars 613 remain upright, and a retracted state in which the snap bars 613 are deformed. In the relaxed state, the inserted portions of the snap bars 613 remain separated; in the retracted state, the inserted portions of the snap bars 613 converge inward, shrinking the upper portion of the spacers 614. When the snap portion 612 is in the relaxed state, its outer diameter at its maximum outer diameter (i.e., the diameter of the circle where the outer edge of the hook is located) is larger than the inner diameter of the mounting hole 51. When the snap portion 612 is in the retracted state, its outer diameter at its maximum outer diameter is smaller than the inner diameter of the mounting hole 51, allowing the snap portion 612 to be inserted into the mounting hole 51 for installation.

[0056] 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 10 and Figure 11As shown, the pressure ring 62 comprises a main body 621 and an operating portion 622. The main body 621 is annular and is positioned outside the buckle portion 612 and located at one end of the fastener 63. The operating portion 622 is integrally formed at the end of the main body 621 away from the fastener 63 and protrudes inward to form a plurality of inserts 623 that can be inserted into the spacers 614 when the buckle portion 612 is in the relaxed state. The number of inserts 623 is equal to the number of spacers 614, and each insert 623 is inserted into a corresponding spacer 614. The span of the spacer 614 along the circumferential direction is greater than the width of the insert 623. A curved guide surface 6231 is provided on one side of the insert 623 to guide the buckle strips 613 toward each other, causing the buckle portion 612 to transition from the relaxed state to the retracted state. A gap is left between the other side of the insert 623 and the side of the buckle strip 613 to facilitate the transition of the buckle portion 612.

[0057] 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, upper and lower end surfaces of the main body 621 are respectively formed with upper grooves and lower grooves, the first sealing ring 651 is installed in the lower groove, and the second sealing ring 652 is installed in the upper groove to enhance the connection tightness and sealing between the water tower, the pressure ring 62 and the fastener 63.

[0058] When the buckle portion 612 is in a relaxed state, the insert 623 is embedded in the spacer 614. Figure 11 As shown, the guide surface 6231 is located on the side of the insert 623 facing the snap strip 613 on the right side. At this time, when the pressure ring 62 is rotated in the clockwise direction, the snap strip 613 located in the rotational direction will move along the guide surface 6231 under the action of the guide surface 6231, thereby approaching the adjacent snap strip 613 and forming a retracted state. Conversely, when the snap portion 612 is in the retracted state, the pressure ring 62 is rotated in the opposite direction (in the counterclockwise direction), and the insert 623 is gradually inserted into the spacer 614 under the action of the guide surface 6231, thereby separating the snap strips 613 and returning them to the relaxed state.

[0059] In order to ensure that the buckle portion 612 is stably fixed on the mounting hole 51, a locking member 64 is also provided. Figure 11 As shown, the locking member 64 is movably arranged on the buckle portion 612, and is combined with Figure 10-14The locking member 64 has a locking portion 641 and a driving portion 642. The locking portion 641 is annular and is located inside the buckle strip 613. It has 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 the relaxed state. Figure 14 and Figure 13 As shown, the inner side of the snap 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. An annular action surface 6133 that protrudes inward and is used to interact with the locking portion 641 is formed on the upper inner side of the snap strip 613 with the first inclined guide surface 6132 as the boundary. A locking space for the upper end of the locking portion 641 to be inserted is formed inside the annular action surface 6133. When the upper end of the locking portion 641 is inserted into the locking space, the locking portion 641 can reach the locked position. The provision of the first inclined guide surface 6132 and the second inclined guide surface 6411 can guide the movement of the locking portion 641, so that its upper end can be more easily inserted into the locking space. When the locking portion 641 is in the unlocked position, as shown in FIG. Figure 12 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 retracted state and is removed from or installed into the mounting hole 51; when the locking portion 641 is in the locked position, as shown Figure 14 As shown, at this time, since the locking portion 641 and the annular action surface 6133 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 and formed into 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.

[0060] like Figure 13 and Figure 14 As shown, a plurality of driving parts 642 are spaced apart on the outer circumference of the locking part 641. The driving parts 642 are 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 unlocked position to the locked position. There is a separation area 643 between adjacent driving blocks 642 for the buckle strip 613 to pass through. Figure 13 As shown, the number of driving parts 642 corresponds to the number of spacers 614; the number of snap bars 613 corresponds to the number of partitions 643. When installed, the driving parts 642 extend into the spacers 614 between the snap bars 613, the snap bars 613 are located in the partitions 643, and the bottom of the driving part 642 extends out of the spacers 614 and is placed on the top of the fastener 63. Figure 14As shown, since the fastener 63 is located on the outer periphery of the snap portion 612, in order to ensure that the bottom of the driving portion 642 can 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 inward-retracted annular embedding groove 624 (also known as an avoidance groove). The outer end of the driving block 642 passes through the spacer 614 and is embedded in the annular embedding groove 624. Providing the annular embedding groove 624 below the action portion 622 can also limit the travel of the driving block 642. Since the spacer 614 is open at one end (the upper end) and has a stop edge 6141 at the other end (the lower end) for blocking the driving block 642, the stop edge 6141 forms a lower limit for the bottom of the driving block 642. Because the engaging portion 622 is formed with an insert 623 that can be inserted into the spacer 614, this insert 623 forms an upper limit on the driving block 642. When the latch portion 612 is in the relaxed state, the insert 623 prevents the locking member 64 from falling out, while simultaneously pushing the locking portion 641 back from the locked position to the unlocked position. Furthermore, the threaded segment 611 that engages the fastener 63 is longer than or equal to the length of travel of the locking portion 641 from the unlocked to the locked position, ensuring that the locking portion 641 can normally switch between the unlocked and locked positions.

[0061] In this embodiment, the driving portion 642 is a fan-shaped block structure with a hollowed-out middle portion, which can reduce the weight of the driving portion and save materials. In actual situations, it can also be of other shapes or solid structures. Since the fastener 63 has a rotation direction and a movement direction relative to the connection portion (i.e., the threaded section 611) of the fixing member 82, the setting of the driving block 642 only needs to ensure that the projections of the pressure ring 62, the driving block 642, and the fastener 63 in the movement direction have an overlapping portion. This ensures that the driving block 642 can move from the unlocked position to the locked position under the action of the fastener 63, and can also ensure that the driving block 642 does not fall off under the obstruction of the pressure ring 62. At the same time, the driving block 642 can move from the locked position to the unlocked position under the drive of the pressure ring 62.

[0062] In this embodiment, since the fixing mechanism 300 is used to install the cleaning device 200 on the water tower, in order to install the cleaning device 200, the fixing member 82, the pressure ring 62, and the locking member 64 need to be hollow. That is, the locking portion 641 is annular, and the middle portion can be passed through by the cleaning device 200. In actual situations, the fixing mechanism 300 can also be used in other scenarios where two components need to be fixed. In this case, if it is not necessary to pass the locking portion 641 through the component for installation, the locking portion 641 can also be set as a solid cylindrical shape.

[0063] The fixing method of the fixing mechanism of this embodiment includes the following steps:

[0064] S1: Check the buckle portion 612 and 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. Figure 15 Status shown;

[0065] S2: Rotate the pressing ring 62 clockwise, and the buckle strip 613 shrinks under the action of the pressing ring 62, so that the buckle portion 612 changes to a retracted state, as shown in FIG. Figure 16 In the state shown, after tightening, insert it into the mounting hole 51 from bottom to top;

[0066] S3: After confirming that the buckle portion 612 enters the mounting hole 51, the pressure 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. Figure 17 Status shown;

[0067] S4: Rotate the fastener 63, the fastener 63 moves upward with the pressure ring 62 and the locking member 64, and the locking member 64 moves from the unlocked position to the locked 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. Figure 18 Status shown.

[0068] The disassembly method of the fixing mechanism of this embodiment includes the following steps:

[0069] N1: Rotate the tightening member 63 to loosen it;

[0070] N2: Press the pressing ring 62 downward to drive the locking member 64 downward, so that the locking member 64 moves downward from the locked position to the unlocked position;

[0071] 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, tighten it, and then pull it out from top to bottom. The buckle portion 612 is separated from the mounting hole 51, and the disassembly is completed.

[0072] When the fixing member 82 is installed, the locking member 612 is tightened and the locking member 612 is pulled out of the fixing member 82, and the locking member 612 is pulled out of the fixing member 82. When the fixing member 82 is installed, the locking member 612 is tightened and the locking member 612 is pulled out of the fixing member 82. When the fixing member 82 is installed, the locking member 612 is tightened and the locking member 612 is pulled out of the fixing member 82. When the fixing member 82 is installed, the locking member 612 is tightened and the locking member 612 is pulled out of the fixing member 82.

[0073] Example 2

[0074] This embodiment is based on the above embodiments 1-3. Figure 6 and Figure 7 As shown, the partition plate 827 located near the through hole further defines an air hole 8271 that connects the first mounting cavity 821 with the second mounting cavity 825. A gap is provided between the circumference of the sealing gasket 843 on the driver cap 841 and the inner wall of the fixed sleeve 8261. When the driver cap 841 is not in operation, the active end 8411 of the driver cap 841 blocks the through hole 8262, and the bottom surface of the sealing gasket 843 abuts the inner edge of the through hole 8262, isolating the first mounting cavity 821 within the fixed sleeve 8261 from the outside world. When the sealing gasket 843 moves with the driving cap 841 and separates from the inner edge of the through hole 8262, the gas from the outside enters the first installation cavity 821 through the gaps around the sealing gasket 843 and the driving cap 841 (i.e., the gaps between the sealing gasket 843 and the inner wall of the fixed sleeve 8261, and between the driving cap 841 and the inner wall of the fixed sleeve 8261), and enters the second installation cavity 825 from the air hole 8271.

[0075] In some use cases, when cleaning the bottom of a water tower, the large drop in water flow within the tower can cause excessive negative pressure and increased suction, which can cause the cleaning tube to be flattened, affecting cleaning effectiveness. The structural device of this embodiment allows for the inflow of external air, balancing the air pressure and allowing the cleaning tube to maintain its original shape and prevent it from being flattened, thus enabling normal operation.

[0076] like Figure 7As shown, under the action of negative pressure, the external gas will push the driving cap 841 to compress the elastic part 842 (the elastic part 842 is a spring, and the spring pressure must be set to a rated value in advance), so that the through hole 8262 opens, and the gas will pass through the through hole 8262, the gap between the driving cap 841 and the fixed sleeve 8261, the axial hole gap between the driving shaft 83 and the partition 827, and the air hole 8271 in turn, and enter the second installation cavity 825. The mixed water flow has a deceleration effect, thereby preventing the cleaning tube from being flattened due to negative pressure.

[0077] Example 3

[0078] This embodiment is a simplified version of the above-mentioned embodiments 1-2, that is, the fixing mechanism only has a fixing member 82, a fastener 63 and a sealing portion (that is, the pressure ring and the locking member are eliminated on the basis of embodiment 1), wherein the structures of the fixing member 82 and the fastener 63 are the same as those in the above-mentioned embodiment 1, and the sealing portion includes a sealing gasket arranged on the top surface of the fastener 63 and a third sealing ring 632 pressed between the fastener 63 and the fixing member 82. During installation, the buckle portion 612 on the fixing member 82 is directly tightened by hand to form an inward 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.

[0079] Example 4

[0080] This embodiment is based on the above-mentioned embodiment 3 and is provided with a locking member 64 as in embodiment 1 (that is, the pressure ring 62 is cancelled 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 82. During installation, the buckle portion 612 on the fixing member 82 is directly tightened by hand to form an inward 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 the relaxed state, and then the fastener 63 is rotated. The locking member 64 moves up to the locked state under the push of 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.

[0081] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention shall be included within the scope of protection of the present invention. For example, in the above embodiments, the installation direction of the fixing mechanism is from bottom to top, and the removal direction is from top to bottom. This is because the above embodiments are for installation at the bottom. In actual situations, the installation direction can be adaptively adjusted according to the actual installation location. For example, if 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.
