Description

Technical Field

[0001] The invention belongs to the technical field of sewage suction and discharge, and particularly relates to an insect bionic sewage suction device. 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, and when working, the cleaning pipe rotates along the bottom of the water tower. During the rotation process, since bristles are provided on the cleaning pipe, the scale at the bottom of the water tower is swept down by the bristles on the cleaning pipe and then discharged through the pipe body. Although this structure can better solve the problem of continuous water cleaning of the water tank. However, new problems are found in the actual use process: since the cleaning pipe (i.e. the cleaning pipe in the above patent) usually adopts a hose, it is difficult to ensure the rotation consistency of the entire cleaning pipe during the rotation process, that is, it cannot rotate smoothly and evenly, especially for a longer hose, when rotating, the inner end is the driving end, which is easy to be driven to rotate first, and the closer to the outer end, the farther the distance, and under the resistance of accumulated water inside the water tower, it is easy to cause the outer end to rotate lagging, which ultimately leads to poor cleaning effect. Summary of the invention

[0005] The purpose of the present invention is to solve the above problem and provide an insect bionic sewage suction device with a simple structure, which can support the sewage suction hose to ensure that the pipeline can improve the rotation consistency of the pipeline.

[0042] Embodiment 1:

[0043] This embodiment provides an insect bionic dirt suction device for installation in a water tower to clean the water tower. Figure 1 As shown, the insect bionic sewage suction device includes a sewage suction hose 40 and a support frame 10. The sewage suction hose 40 includes a tube body 41 and a plurality of sewage suction nozzles 42. The support frame 10 is installed on the outside of the tube body 41 to support the tube body 41 and has a support member 1.

[0044] Among them, a plurality of sewage suction 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 sewage suction nozzle 42 is combined with the tube body 41, and the other end has a sewage suction port 43. A sewage suction channel 44 connecting the sewage suction port 43 and the inside of the tube body 41 is provided inside the sewage suction nozzle 42, and a straight opening 45 is provided near the sewage suction port 43 of the sewage suction nozzle 42, thereby dividing the sewage suction 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 sewage suction nozzle 42 can deform the upper half 451 and the lower half 452 of the sewage suction 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 sewage suction nozzles, thereby improving the cleanliness of impurities at the bottom of the adsorption water tower, and having a wider range of applications.

[0045] like Figure 5-Figure 7 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 sewage suction 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 sewage suction 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 sewage suction 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 7 As shown, Figure 7 for Figure 5 B is a side view of the sewage suction nozzle 42 located on the second surface 53), so as to adjust the sewage suction port 43 to adapt to the bottom surface of the water tower.

[0046] In this embodiment, the length of the lower half piece 452 is shorter than the length of the upper half piece 451. Figure 2 As shown, when the sewage suction hose 40 is installed at the bottom of the water tower, the lower half 452 of the sewage suction 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.

[0047] 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.

[0048] 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 sewage suction nozzle 42 protrudes outward to form a second reinforcing convex ring, which can increase the surface strength of the tube body 41 and the sewage suction nozzle 42 to prevent them from being flattened by water pressure.

[0049] The tube body 41 and the sewage suction 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.

[0050] 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.

[0051] like Figure 8 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.

[0052] Specifically, Fig. 9 and Fig.10As 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.

[0053] 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.

[0054] like Figure 10-13 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.

[0055] like Fig.13 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 suction nozzle 42 located on the side extends out from the side through the notch 17. Figure 2 and Figure 3As shown, the notch 17 is an opening provided on 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 suction nozzle 42.

[0056] like Figure 8 and Fig. 9 As 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.

[0057] 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.12 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.

[0058] like Fig.14 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.

[0059] Specifically, the head end connector 20 is used to be installed at the connection point between the sewage suction hose 40 and the rotary drive component connector. 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.14 As 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 is provided on the head end support body 21 along the length direction of the head end support cavity 23 for the suction nozzle 42 to extend out.

[0060] Similarly, the tail end connector 30 also has a similar structure, such as Fig.15 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.15 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 suction nozzle 42 to extend out.

[0061] 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 .

[0062] 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 suction hose 40 to rotate stably but also provide support force to the suction hose 40 to ensure that it is not crushed due to the influence of water pressure.

[0063] Example 2

[0064] The difference between this embodiment and the above embodiment lies in the difference in the structure of the sewage suction nozzle 42 of the sewage suction hose 40. Fig.16As shown, the sewage suction hose 40 of this embodiment has a tube body 41 and a plurality of sewage suction nozzles 42 closely arranged on one side of the tube body 41 along the length direction of the tube body 41. The sewage suction 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 sewage suction port 43. The sewage suction nozzle 42 is provided with a sewage suction channel connecting the sewage suction port 43 and the inside of the tube body 41. A semicircular scraping part 46 is formed on one side of the sewage 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 sewage suction 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 sewage suction nozzle 42 along the sewage suction port 43. The outer periphery of the sewage suction 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.

[0065] Example 3

[0066] This embodiment is based on the above embodiments 1 and 2. Fig.16 As shown, the sewage suction hose 40 has a mounting end 47 and an outer end 48, wherein the mounting end 47 is used to be mounted on the power body of the cleaning device, and the outer end 48 is arranged away from the mounting end 47, and 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, and 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 enters only through the sewage suction port 43 on the sewage suction nozzle 42, and then enters the tube body 41 along the sewage suction channel 44, and then flows out from the open end.
