Description

Technical Field

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

[0002] Water tanks (or water towers) are usually installed high up on the roof, and some are even installed on the slope of the roof. The water tanks themselves are relatively high and have a smooth surface. If the cleaning staff climbs up to clean the water tanks, they are likely to slip, so cleaning the water tanks 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 relatively deep and cannot be reached by hand, tools such as 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, the applicant's prior invention patent application CN 110773528 A proposed an automatic water tower cleaner, the main cleaning method of which is: the cleaner is installed at the bottom of the water tower, the cleaning pipe for cleaning (i.e., the cleaning pipe in the above patent) is attached to the bottom of the water tower, the cleaning pipe is formed by a main body and a plurality of bristles, each bristle is provided with a sewage suction port, the sewage suction port leads to the main body, and the sewage suction port on each bristle is the same size, the sewage suction capacity and the action surface are the same, and the function of uniform sewage suction is achieved. When working, the cleaning pipe rotates along the bottom of the water tower, and during the rotation process, the bristles scrape the scale at the bottom of the water tower and then suck it into the pipe body through the sewage suction port on the bristles, and finally discharge it through the pipe body. Although this structure can better solve the problem of continuous water cleaning of the water tank, new problems are found during actual use: in practice, the diameter of the sewage suction port of the bristles is certain, and the actual sewage suction area is determined by the angle formed between the bristles and the bottom surface of the water tower during work. When the bottom surface is a flat surface, the actual effective area of ​​the sewage suction port of each bristle is basically the same, so each bristle can evenly absorb sewage during movement. However, for some water towers with uneven bottom surfaces or environments with step structures on the bottom surface, when the cleaning pipe is attached to the bottom surface, the bristles of the cleaning pipe located at the step will be lifted up due to the step surface, and the angle between the bristles and the step surface will become smaller, or even float to a position where it cannot contact the step surface. At this time, the effective area of ​​the sewage suction port of the bristles here will increase, and the water flow here will increase when absorbing water, so that the nearby water flow will be concentrated here for discharge, which will reduce the water flow of the bristles near the steps, and ultimately lead to uneven scale treatment and affected cleaning effects.

[0052] The present invention will be further described below in conjunction with specific embodiments:

[0053] Embodiment 1:

[0054] This embodiment provides a water tower cleaning system, in particular, a cleaning system installed at the bottom of the water tower 5, which is 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 water tower cleaning system includes a cleaning device 100, a driving device 200 and a fixing device 300. The driving device 200 is installed inside the fixing device 300 and has a driving part. The driving part is connected to the cleaning device 100 and is used to drive the cleaning device 100 to rotate, so as to clean the bottom of the water tower 5. The fixing device 300 is used to fix the cleaning device 100 and the driving device 200 on the water tower 5. The fixing device 300 has a fixing part 82, and a space for installing the driving device 200 is formed inside the fixing part 82.

[0055] <Cleaning device>

[0056] like Figure 3-Figure 17As shown, the cleaning device 100 is an insect bionic cleaning device, including a cleaning hose 40, a connecting pipe 70 and a supporting frame 10. The cleaning hose 40 includes a tube body 41 and a plurality of cleaning nozzles 42. The tube body 41 has a mounting end 47 and an outer end 48. The mounting end 47 is mounted on the connecting pipe 70, and the outer end 48 is arranged away from the mounting end 47. The supporting frame 10 is mounted on the outer side of the tube body 41 to support the tube body 41, and has a supporting member 1. During the rotation process, the cleaning nozzle 42 will scrape off the scale impurities attached to the bottom surface of the water tower, and then suck in the sewage mixed with impurities and discharge it from the tube body 41 to the connecting pipe 70.

[0057] Among them, a plurality of cleaning nozzles 42 are closely arranged on one side of the tube body 41 along the length direction of the tube body, one end of the cleaning nozzle 42 is combined with the tube body 41, and the other end has a sewage suction port 43, and a sewage suction channel 44 connecting the sewage suction port 43 and the inside of the tube body 41 is provided inside the cleaning nozzle 42, and a straight opening 45 is provided near the sewage suction port 43 of the cleaning nozzle 42, thereby dividing the cleaning nozzle 42 into an upper half 451 and a lower half 452. The straight opening 45 provided near the sewage suction port 43 of the cleaning nozzle 42 can deform the upper half 451 and the lower half 452 of the cleaning nozzle 42 when encountering a use scenario such as an uneven sewage suction surface or a step structure, so that it fits more closely with the bottom surface, so as to reduce the gap between the cleaning nozzles, thereby improving the cleanliness of impurities at the bottom of the adsorption water tower, and having a wider range of applications.

[0058] like Figure 6-Figure 8 As shown, taking a water tower with a step at the bottom as an example, a step structure 51 is provided in the middle of the bottom surface of the water tower, which separates the bottom surface of the water tower into a first surface 52 and a second surface 53 of different heights. The cleaning hose 40 is installed at a position close to the bottom surface. Due to the setting of the step structure 51, the position of the cleaning nozzle 42 is slightly misaligned. In this embodiment, taking the example that the height of the first surface 51 is lower than the height of the second surface 53, during the rotation of the cleaning nozzle 42 located on the second surface 53, the upper half 451 and the lower half 452 of the sewage suction port 43 may be deformed (such as Figure 8 As shown, Figure 8 for Figure 6 B is a side view of the cleaning nozzle 42 located on the second surface 53) to adjust the sewage suction port 43 to adapt it to the bottom surface of the water tower.

[0059] In this embodiment, the length of the lower half piece 452 is shorter than the length of the upper half piece 451. Figure 4 As shown, when the cleaning hose 40 is installed at the bottom of the water tower, the lower half 452 of the cleaning hose 40 is located at the bottom, and the upper half 451 covers the lower half 452. The length of the lower half 452 is set to be shorter than the length of the upper half 451, which can ensure that the scale scraped off can be brought into the sewage suction channel 44 by the water flow along the sewage suction port 43, and then discharged along the tank body 41.

[0060] In this embodiment, the upper half piece 451 is flat, and the lower half piece 452 is in an arc shape opening toward the upper half piece 451. The lower half piece 452 can scrape off the scale during rotation, and then the scale is brought into the sewage suction channel 44 along the sewage suction port 43 by the water flow under the drive of the lower half piece 452.

[0061] In this embodiment, the outer circumference of the tube body 41 protrudes outward to form a first reinforcing convex ring 411, and the outer circumference of the cleaning nozzle 42 protrudes outward to form a second reinforcing convex ring, which can increase the surface strength of the tube body 41 and the cleaning nozzle 42 to prevent them from being flattened by water pressure.

[0062] The tube body 41 and the cleaning nozzle 42 are formed of a soft rubber material into an integral structure, which is deformable and convenient for adapting to water towers with different bottom structures.

[0063] The inner wall of the tube body 41 is provided with a counterweight portion, which can be a protrusion formed on the inner wall of the tube body 41, or a separate counterweight block inserted separately to increase the weight of the tube body 41, thereby ensuring that the tube body 41 can be attached to the surface of the bottom of the water tower during operation.

[0064] like Fig. 9 As shown, the support frame 10 includes a head end joint 20, a tail end joint 30 and a support member 1, and the support member 1 is installed between the head end joint 20 and the tail end joint 30. In this embodiment, n support members 1 are provided (n is an integer greater than or equal to 2), wherein each support member 1 has the same structure, and the support member 1 is used to be sleeved on the outer periphery of the main body of the pipeline to support the main body of the pipeline and increase the rigidity of the pipeline, so that the pipeline can rotate more consistently and evenly. In addition, since the support member is sleeved outside the pipeline, it can also prevent the main body of the pipeline from being flattened and deformed due to external pressure.

[0065] Specifically, Fig.10 and Fig.11 As shown, the support member 1 includes a support body 11, which is in the shape of a cylindrical sleeve, has a support cavity 13 in the middle for the pipe body to extend into, and a connection seat 12 is formed at the bottom. The connection seat 12 is in the shape of a plate and is arranged at the bottom of the support body 11 along the length direction. In the length direction, a male connection part 14 is provided at one end of the connection seat 12, and a female connection part 15 is provided at the other end. The male connection part 14 and the female connection part 15 are respectively protruded from the corresponding end faces (i.e., the front and rear end faces along the length direction) of the support body 11, and a connection column 141 is formed on the male connection part 14, and a connection hole 151 matching the connection column 141 is opened on the female connection part 15.

[0066] The central axis directions of the connecting column 141 and the connecting hole 151 are perpendicular to the central axial direction of the support cavity 13, so that when the connecting column 141 and the connecting hole 151 cooperate, the left-right and front-back shaking between the two support members 1 can be limited. In other words, the support members 1 can only swing up and down, and the axis of the connecting column 141 is placed at the bottom of the entire support member 1, so that when the device moves upward, the gap between the parts is completely turned to the upper limit position. One end of the connecting column 141 is integrally connected to the male connecting part 14, and the other end is formed with an elastic buckle part 142 that can be clamped on the edge of the connecting hole 151. The entire connecting column 141 is elastic and easy to assemble during installation. After installation, the design of the elastic buckle part 142 can prevent it from falling off after assembly. An arc surface 152 is formed at one end of the female connecting part 15 away from the connecting seat 12, and an arc groove 143 matching the arc surface 152 is provided on the side of the male connecting part 14 facing the connecting column 141.

[0067] like Figure 11-Figure 14 As shown, a groove 111 is formed on the inner wall of the support body 11, and a counterweight 16 is installed in the groove 111 to ensure that the support member 1 can avoid displacement or floating due to being too light when it is sleeved on the outer periphery of the pipe, so that the pipe can fit as closely as possible with the bottom surface of the water tower (i.e., the clean surface). In particular, when the internal pipe is a cleaning pipe at the bottom of the water tower, a counterweight block is added inside to prevent the cleaning pipe from not being close to the bottom of the water tower and then failing to fully absorb dirt due to the buoyancy of water and the traction driven by the rotating gear set. In actual situations, the counterweight 16 can also be formed integrally by the support body 11, that is, the inner wall of the support body 11 protrudes inward to form a counterweight block. In order to enhance the fit, a corresponding counterweight can also be provided in the tube body 41.

[0068] like Fig.14 As shown, a notch 17 is provided on the support body 11 along the length direction of the support cavity 13. When the support member 1 is installed, the tube 41 extends into the support cavity 13, and the cleaning nozzle 42 located on the side extends out from the side through the notch 17. Figure 4 and Figure 3 As shown, the notch 17 is an opening provided in the support body 11 near the connection seat 12 and opened along the length direction of the support body 11. In actual situations, the notch can also be a plurality of through holes arranged along the length direction of the support body 11, each through hole corresponding to each cleaning nozzle 42.

[0069] like Fig. 9 and Fig.10As shown, a plurality of support members 1 are connected end to end, specifically, the male connection portion 14 of the i-th support member 1 is detachably and rotatably connected to the female connection portion 15 of the i+1-th support member 1, and there is a gap between the support body 11 of the i-th support member 1 and the support body 11 of the i+1-th support member 1, wherein i is an integer greater than or equal to 1, that is, two adjacent support members 1 are connected together through male and female connection buckles. Conversely, the connection hole of the i-th support member can also be detachably and rotatably connected to the connection column of the i+1-th support member.

[0070] The male connection part 14 of the i-th support member 1 is formed with a stopper that can abut against the side of the female connection part 15 of the i+1-th support member 11, or the male connection part 14 of the i+1-th support member 1 is formed with a stopper that can abut against the side of the female connection part 15 of the i-th support member 1. That is, Fig.13 As shown, the male connection part 14 protrudes toward one side of the other support member 1 to form a limiting part 18. The limiting part is a step structure, which can be clamped on the edge of the support body 11 on the other support member 1, and the side abuts against the side of the female connection part 15 of the other support member 1, so that when the two support members 1 are connected together, it can form a limit on the bottom to prevent excessive space when moving downward, and can be used to prevent the angle of lateral movement between the support members 1 from being too large, causing the internal pipe to be flattened or unstable. There is a gap between the support bodies 11 of the two support members 1, and a limit can be formed on the upper part to limit the amplitude of the up and down swing between the two support members, thereby avoiding the up and down shaking of the support members due to excessive rotation angles during use, and ensuring the stability of the support members. At the same time, combined with the direction setting of the above-mentioned connecting column 141, such a design can prevent the pipe located in the support member from being flattened due to the influence of excessive movement of the support member, and also ensure that it is relatively straight during installation, which is easy to install.

[0071] like Fig.15 As shown, the end of the head end joint 20 facing the support member 1 is provided with a male connection part 14 or a female connection part 15 which is the same as the above-mentioned support member 1, and the end of the tail end joint 30 facing the support member 1 is also provided with a female connection part 15 or a male connection part 14 which is the same as the above-mentioned support member 1.

[0072] Specifically, the head end connector 20 is used to be installed at the connection point between the cleaning hose 40 and the connecting pipe 70. The head end connector 20 has a head end support body 21 similar to the above-mentioned support member 1. The middle part of the head end support body 21 is provided with a head end support cavity 23, and the bottom is provided with a head end connection seat 22. The head end connection seat 22 is provided with a head end female connection part 25 (which can also be a head end male connection part) at one end facing the support member 1. Fig.15As shown, taking the head end female connection part 25 as an example, the head end female connection part 25 is connected to the male connection part 14 on the first support member 1, and a head end notch 24 for the cleaning nozzle 42 to extend is opened on the head end support body 21 along the length direction of the head end support cavity 23.

[0073] Similarly, the tail end connector 30 also has a similar structure, such as Fig.16 As shown, the tail end connector 30 has a tail end support body 31 similar to the above-mentioned support member 1, a tail end support cavity 33 is provided in the middle of the tail end support body 31, a tail end connection seat 32 is provided at the bottom, and a tail end male connection portion 35 (which can also be a tail end female connection portion) is provided at one end of the tail end connection seat 32 facing the support member 1, as shown in FIG. Fig.16 As shown, taking the tail end male connection part 35 as an example, the tail end male connection part 35 is connected to the female connection part 15 on the last support member 1, and a tail end notch 34 is provided on the tail end support body 31 along the length direction of the tail end support cavity 33 for the cleaning nozzle 42 to extend out.

[0074] The structures and dimensions of the female connection part 25 at the head end and the male connection part 35 at the tail end are respectively the same as those of the female connection part 15 and the male connection part 14 on the support member 1 .

[0075] Since the head end joint 20 and the tail end joint 30 have a similar structure to the support member 1 and can be connected with the support member 1 by male and female buckles, it is convenient to disassemble and install, and the movement between the adjacent support members is limited in both the front and rear and left and right directions, and only a small swing in the up and down direction can be achieved. The shape and movement of the entire support frame 10 are like an insect, which can not only allow the cleaning hose 40 to rotate stably but also provide support force to the cleaning hose 40 to ensure that it is not crushed due to the influence of water pressure.

[0077] The driving device 200 is an impeller driving device, such as Figure 2 As shown, the impeller driving device includes: an impeller 81, an input drive part 84, an output drive part 85 and a water diversion part 86, and the impeller 81, the input drive part 84, the output drive part 85 and the water diversion part 86 are all installed in the fixing part 82. Among them, the fixing part 82 has a first installation cavity 821 for installing the input drive part 84 and a second installation cavity 825 for installing the impeller 81; the impeller 81 is provided with a driving shaft 83, and the driving shaft 83 can extend into the first installation cavity 821 and cooperate with the input drive part 84.

[0078] like Fig.18 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 Fig.19The state shown) and the non-working state separated from the drive shaft 83 (as shown Fig.18 In the state shown in the figure), the elastic member 842 is installed in the first installation cavity 821, and is used to act on the drive cap 841 to keep the drive cap 841 in a 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 a non-working state to a 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.

[0079] like Figure 2 , Figure 18-19 As shown, the fixing part 82 comprises a sleeve body 822, a fixing seat 823 and a fixing cover 826. The fixing seat 823 is fixed at one end of the sleeve body 822 and a sealing ring is pressed between the two. The sleeve body 822 is hollow inside, and a receiving chamber 824 is formed to accommodate the output drive part 85 and the water diversion part 86. A second installation chamber 825 is provided in the middle of the fixing seat 823 on one side facing the receiving chamber 824, and the impeller 81 is at least partially installed in the second installation chamber 825. A first installation chamber 821 is provided in the middle of the fixing seat 823 on one side away from the receiving chamber 824, and the fixing cover 826 is installed on the fixing seat 823 on the side where the first installation chamber 821 is located. The fixing seat 823 also has a partition plate 827 in the middle for separating the second installation chamber 825 from the first installation chamber 821, and a through hole is provided in the middle of the partition plate 827 for the drive shaft 81 to pass through.

[0080] 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 hollow 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 action end 8411 and a driving end 8412 for combining with the driving shaft 83. The fixing cover 826 is opened (such as Fig.19The middle part of the bottom surface shown in the figure is provided with a through hole 8262 for exposing the end face of the action end 8411, and a socket 8413 for inserting the drive shaft 83 is provided on the drive end 8412, and the socket 8413 has a shape that matches the drive shaft 83. A sealing gasket 843 is installed near the through hole 8262 of the action end 8411, and the side of the sealing gasket 843 facing the through hole 8262 is used to seal on the inner edge of the through hole 8262, and a cross or straight notch is provided on the end face of the action end 8411, so that the user can insert a tool (such as a cross or straight screwdriver) and then push the drive cap 841 to move and rotate.

[0081] 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 fixed portion 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 fixed seat 823 of the fixed portion 82, and a water outlet channel 8281 leading to the second installation cavity 825 is opened 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.

[0082] like Figure 2 and Fig.19 As shown, the water guide portion 86 has a mounting sleeve 862 and a water guide plate 863. The water guide plate 963 is spirally arranged on the outer periphery of the mounting sleeve 862 to form a spiral water guide channel 861. Figure 5 The water guide plate 963 is located at the end of the water guide channel 861 and is inclined toward the blade interval of the impeller 81, so as to better guide the water flow into the blade interval of the impeller 81 to push the blades to make the impeller 81 rotate. Figure 2 As shown, the interior of the mounting sleeve 862 is hollow, and sealing members are provided at both ends in the extension direction, and 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 sealing protection, which can prevent water from entering the sealing cavity and affecting the output drive unit 85.

[0083] like Figure 2 As shown, one end of the connecting pipe 70 extending into the fixed part 82 is combined with the output drive part 85 in the fixed part 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 part 86 in the fixed part 82, as shown in FIG. Figure 5As shown, a mounting seat 8625 for mounting the connecting pipe 70 is formed at one end of the mounting sleeve 862, and a water hole 8625 for connecting the water inlet channel 73 and the water diversion channel 861 is formed on the mounting seat 8625. 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.

[0084] The driving principle of the cleaning tube of this embodiment is as follows: the water from the cleaning hose 40 flows 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 flow to the impeller 81, pushing the impeller 81 to rotate, and then driving the output drive part 85 to rotate through the output shaft. During the rotation of the output drive part 85, the connecting tube 70, the cleaning hose 40 and the supporting frame 10 will also rotate together, thereby cleaning the bottom of the water tower.

[0085] The recovery principle of the impeller 81 stuck in this embodiment is as follows: when the impeller 81 is stuck due to impurities during operation, the driving cap 841 can be pushed by a tool (such as a screwdriver) to move the driving cap 841 toward the driving shaft 83 and combine with the driving shaft 83, and then the driving cap 841 is rotated by manual force, and 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 can be shaken off to release the stuck situation and allow the impeller 81 to resume normal operation. Finally, the tool is pulled out, and the driving cap 841 returns to a non-working state driven by the elastic member 842. After the tool is pulled out, the impeller 81 can still continue to work driven by the water flow.

[0086] In this embodiment, the impeller 81 can be a rubber impeller, with a drive shaft 83 installed in the middle, and the output drive part 85 is a planetary gear set, which has an input gear, and one end of the drive shaft 83 is connected to the input gear, and the planetary gear set is driven to rotate by the drive shaft 83. Since one end of the drive shaft 83 is directly connected to the output drive part 85, if the output drive part 85 (planetary gear set) is stuck, the bottom drive cap 841 can be directly pushed into the drive shaft 83 by a screwdriver, and then the screwdriver is rotated to replace the rubber impeller 81 to drive the bottom of the planetary gear set to make the gear rotate again, which is very convenient.

[0087] This embodiment can also realize manual driving of the cleaning tube to rotate and clean, 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 is combined with the driving shaft 83, and then manually apply force to rotate the driving cap 841, and 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 pipe 71 and the cleaning hose 40 to rotate together, so as to realize manual driving of the cleaning tube to rotate and clean by continuous manual force. After cleaning is completed, the tool can be pulled out.

[0088] <Fixed device>

[0089] The fixing device 300 includes a fixing portion 82, a pressure ring 62, a fastener 63, a locking member 64 and a sealing portion. The fixing portion 82 is in the shape of a shell, and a driving device 200 is installed inside. The driving device 200 is installed on the mounting hole 51 at the bottom of the water tower 5 through the fixing portion 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 portion 82, and between the fixing portion 82 and the edge of the mounting hole 51.

[0090] The fixing portion 82 has a sleeve body 822 in a sleeve shape. Fig.23 and Fig.24 As shown, a connecting portion is provided above the sleeve body 822, and the connecting portion is a threaded segment 611. The fastener 63 is a rotating sleeve (such as a nut) with an internal thread 631 inside. 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 portion 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 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 snap-fit ​​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 snap-fit ​​hook 6131, which is convenient for guiding when installed in the mounting hole 51.

[0091] 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.

[0092] 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. Fig.25 and Fig.26 As 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.

[0093] 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.

[0094] When the buckle portion 612 is in a relaxed state, the insert 623 is embedded in the spacer 614. Fig.26 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.

[0095] 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. Fig.26 As shown, the locking member 64 is movably disposed on the buckle portion 612, and is combined with Figure 25-Figure 29 The 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 a relaxed state. Fig.29 and Fig.28 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. 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 buckle 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 locking 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. Fig. 27 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. Fig.29 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, the buckle strip 613 cannot be deformed and formed into a retracted state under the drive of the pressure ring 62 due to the blocking of the locking portion 641, 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.

[0096] like Fig.28 and Fig.29 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.28 As 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. Fig.29 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.

[0097] 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 part 82, 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, it can also allow the driving block 642 to move from the locking position to the unlocking position under the drive of the pressing ring 62.

[0098] In this embodiment, since the fixing device 300 is used to install the cleaning device 200 on the water tower, in order to install the cleaning device 200, the fixing portion 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 part can be passed through by the cleaning device 200. In actual situations, the fixing device 300 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.

[0099] The fixing method of the fixing device of this embodiment comprises the following steps:

[0100] 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.30 Status shown;

[0101] 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.31 In the state shown, after tightening, insert it into the mounting hole 51 from bottom to top;

[0102] 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.32 Status shown;

[0103] 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.33 Status shown.

[0104] The disassembly method of the fixing device in this embodiment comprises the following steps:

[0105] N1: Rotate the tightening member 63 to loosen it;

[0106] 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;

[0107] 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.

[0108] As can be seen from the above, the fixing device 300, fixing method and disassembly method of the water tower cleaning system provided by the present invention, since a buckle portion 612 is provided on the fixing portion 82, 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 to form a retracted 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 retracted 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 to form a retracted 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, and the technical requirements are reduced.

[0109] Example 2

[0110] The difference between this embodiment and the above-mentioned embodiment lies in that in the cleaning device 200, the cleaning nozzle 42 of the cleaning hose 40 has a different structure, such as Fig.17 As shown, the cleaning hose 40 of this embodiment has a tube body 41 and a plurality of cleaning nozzles 42 closely arranged on one side of the tube body 41 along the length direction of the tube body 41. The cleaning nozzle 42 is in the shape of a circular tube, one end of which is connected to the tube body 41, and the other end is provided with a suction port 43. The cleaning nozzle 42 is provided with a suction channel connecting the suction port 43 with the inside of the tube body 41. A semicircular scraping part 46 is formed on one side of the suction port 43. When in use, the opening of the scraping part 46 faces one side of the bottom surface. During the rotation of the cleaning hose 40, the scraping part 46 scrapes from the bottom surface to scrape off the scale attached to the bottom surface, and then the scale impurities scraped off are carried by the water flow into the cleaning nozzle 42 along the suction port 43. The outer periphery of the cleaning nozzle 42 protrudes outward to form a second reinforcing convex ring 421, which has a similar function to the first reinforcing convex ring 411 on the outer periphery of the tube body 41, that is, to strengthen the strength of the structure itself to avoid being flattened by water pressure.

[0111] Example 3

[0112] This embodiment is based on the above embodiments 1 and 2. Fig.17 As shown, the outer end 48 is tapered. In order to match this shape, the outer contour of the tail end support body 31 of the tail end joint 30 is also tapered, that is, the outer diameter of the end away from the support member 1 is smaller than the outer diameter of the end of the tail end support body 31 close to the support member 1, thereby forming support for the outer end 48. The tube body 41 can be in the form of one end open and the other end closed, the open end is the mounting end 47, which is used to connect to the driving device (used to drive the tube body 41 to rotate and suck in and discharge the water flow), and the water flow only enters through the sewage suction port 43 on the cleaning nozzle 42, and then enters the tube body 41 along the sewage suction channel 44, and then flows out from the open end.

[0113] Example 4

[0114] This embodiment is based on the above embodiments 1-3. Fig.21 and Fig. 22 As shown, the partition plate 827 near the through hole is also provided with an air hole 8271 connecting the first installation cavity 821 and the second installation cavity 825, and a gap is left between the peripheral surface of the sealing gasket 843 on the driving cap 841 and the inner wall of the fixed sleeve 8261. When the driving cap 841 is in a non-working state, the action end 8411 of the driving cap 841 is blocked at the through hole 8262, and at this time, the bottom surface of the sealing gasket 843 is attached to the inner edge of the through hole 8262, so that the first installation cavity 821 inside the fixed sleeve 8261 is separated from the outside. 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 gap between the sealing gasket 843 and the inner wall of the fixed sleeve 8261, and the gap 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.

[0115] In some use scenarios, when cleaning the bottom of a water tower, the water flow in the water tower has a large drop, which causes excessive negative pressure and increased suction, causing the cleaning tube to be sucked flat, affecting the cleaning effect. The structural device of this embodiment can be used to replenish the outside air and balance the air pressure, so that the cleaning tube can remain in its original shape and not be sucked flat for normal operation.

[0116] like Fig. 22As shown, under the action of negative pressure, the external gas will push the driving cap 841 to compress the elastic member 842 (the elastic member 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.

[0117] Example 5

[0118] The present embodiment is a simplified version of the above-mentioned embodiments 1-4, that is, the fixing device only has a fixing portion 82, a fastener 63 and a sealing portion (that is, the pressure ring and the locking member are eliminated on the basis of the embodiment 1), wherein the structures of the fixing portion 82 and the fastener 63 are the same as those of 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 portion 82. During installation, the buckle portion 612 on the fixing portion 82 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 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.

[0119] Example 6

[0120] In this embodiment, a locking member 64 as in embodiment 1 is provided on the basis of the above-mentioned embodiment 5 (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 portion 82. During installation, the buckle portion 612 on the fixing portion 82 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.

[0121] 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 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, if the installation hole is located at the top, the buckle portion 612 needs to be facing downward and installed on the installation hole from top to bottom.
