Description

Technical Field

[0001] This utility model relates to an auxiliary device for cleaning sedimentation tanks that can avoid damage to inclined tubes, and belongs to the field of sedimentation tank cleaning technology. Background Technology

[0002] In traditional water treatment processes, sedimentation tanks are crucial for removing large particles and reducing raw water turbidity. Their performance largely determines the load on subsequent filters and the overall water treatment efficiency. Typically, to enhance sedimentation and shorten settling time, inclined tubes are installed at the bottom of the sedimentation tank to form dense sedimentation channels. The large surface area allows flocs and other suspended solids to rapidly coagulate, settle, and accumulate in the bottom sludge hopper within a short hydraulic retention time, achieving rapid and efficient solid-liquid separation. Inclined tubes are often made of lightweight, corrosion-resistant materials (such as PVC and PP), meeting certain mechanical stability requirements and facilitating large-scale installation and replacement. However, due to their relatively limited mechanical strength, inclined tubes are not suitable for bearing large additional loads, especially the weight of manual trampling. If an inclined tube ruptures or deforms due to excessive pressure, it will not only lose its original sedimentation function but may also trigger secondary impacts from sludge and other pollutants, ultimately affecting the stable operation of the entire water treatment system.

[0003] Furthermore, during long-term use, inclined tubes inevitably absorb and accumulate various sludge, rust, and other suspended solids. If these impurities are not cleaned in a timely and effective manner, they can easily cause blockage of the inclined tube channels or uneven water flow, significantly reducing sedimentation efficiency and adversely affecting the treatment load of subsequent filter beds and disinfection processes. Since sedimentation tanks are often large in area and deep, it is difficult for workers to reach the central area of ​​the inclined tubes by extending high-pressure water pipes along the perimeter of the tank wall to perform localized flushing or brushing.

[0004] The current method used by waterworks is to have staff walk directly on the inclined pipes at the bottom of the sedimentation tank to move and clean it. However, this method has a problem: the inclined pipes were not designed to bear the weight of people or other heavy loads, and they are very easy to be damaged by being stepped on, such as cracking, breaking, or local denting and deformation.

[0005] In summary, current methods for cleaning inclined tubes in sedimentation tanks have the following shortcomings: 1) There is a lack of effective cleaning methods that can fully cover the inclined tubes at the bottom of the sedimentation tank, resulting in cleaning blind spots; 2) Manual trampling can easily damage the inclined tube structure, significantly shortening its service life. Against this backdrop, this invention aims to develop a novel cleaning device or system that can achieve full coverage and high-efficiency cleaning of the inclined tubes at the bottom of the sedimentation tank without requiring direct manual trampling, thereby effectively extending the service life of the inclined tubes. Summary of the Invention

[0016] The counterweight is a spherical cap smaller than a hemisphere of the same radius. The plane of the counterweight is fixedly connected to the lower surface of the main body. The central axis of the counterweight coincides with the central axis of the main body. The density of the counterweight is greater than that of water, and the radius of the plane of the counterweight is smaller than the radius of the main body.

[0017] Furthermore, the longitudinal movement mechanism includes a track and a track vehicle;

[0018] The two ends of the track are fixedly connected to the walls of the sedimentation tank, and the track car is movably connected to the track along the length of the track.

[0019] The railcar includes a fixed plate, a driving wheel, a driven wheel, and a drive motor;

[0020] The fixed plate includes two plates. The driving wheel and the driven wheel are fixedly connected between the two fixed plates. The driven wheel is rotatably mounted between the two fixed plates through a rotating shaft installed between the two fixed plates. The driving wheel is rotatably mounted between the two fixed plates through a rotating shaft fixed on the driving wheel shaft. The minimum distance between the driving wheel and the driven wheel matches the vertical width of the track. The driving wheel and the driven wheel clamp the track in the middle.

[0021] The shaft of the drive wheel is connected to the drive motor.

[0022] Furthermore, the lateral moving mechanism has the same structure as the longitudinal moving mechanism, with the end of the lateral cable fixedly connected to the track of the longitudinal moving mechanism, and the end of the longitudinal cable fixedly connected to the track of the lateral moving mechanism.

[0027] Optionally, the main unit is a power supply, and the cleaning gun is an ultrasonic generator.

[0028] The beneficial effects of this invention are: compared with the prior art,

[0029] 1) This invention uses a lateral and longitudinal moving mechanism to drive the corresponding lateral and longitudinal cables, thereby causing the floating platform on the water surface to move laterally and longitudinally, achieving omnidirectional coverage of all areas of the sedimentation tank. Simultaneously, because the floating platform floats on the water surface within the sedimentation tank, operators can stand on the platform to perform operations without entering the tank and wading, thus avoiding stepping on the inclined tubes and effectively extending their service life.

[0030] 2) This utility model uses a spherical counterweight in combination with a disc-shaped body. On the one hand, the counterweight lowers the center of gravity of the entire floating platform. On the other hand, the radius of the body is greater than the radius of the counterweight, which raises the center of buoyancy of the entire floating platform. The combination of the two makes the center of buoyancy above the center of gravity and increases the distance between the center of gravity and the center of buoyancy, thereby increasing the overall floating stability of the floating platform. This makes it more stable for people to step on the floating platform and less likely to capsize.

[0031] 3) This utility model further increases the stability of the floating platform on the water surface by constraining the floating platform with transverse and longitudinal cables;

[0032] 4) This utility model uses the movement of a railcar on the track to drive the transverse and longitudinal cables to move in the direction of the railcar, thereby realizing the movement of the floating platform.

[0033] 5) This utility model controls the movement of the corresponding railcars of the lateral and longitudinal movement mechanisms by setting the lateral and longitudinal movement control buttons on the upper surface of the floating platform, thereby realizing the control of the floating platform position while cleaning the inclined tube on the floating platform, so as to change the cleaning position.

[0034] 6) This utility model uses horizontal and vertical movement control buttons that are rotated symmetrically around the center of the upper surface of the floating platform, so that a person standing in the center of the floating platform can intuitively press the corresponding button with their foot according to the direction of movement, making operation more convenient.

[0035] 7) This utility model uses a handle on the floating platform to allow people to hold onto the handle when they stand on the platform, thereby stabilizing their center of gravity and ensuring that they will not fall into the water. Attached Figure Description

[0044] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

Figure 3 The left and right sides in the middle correspond to the horizontal direction of the structure in this utility model. Figure 3 The vertical axis of the device in this utility model corresponds to the vertical axis of the device.

[0046] Implementation Example 1:

[0047] like Figure 1-7 As shown, this embodiment provides an auxiliary device for cleaning sedimentation tanks that can avoid damage to the inclined tubes.

[0048] 1. Overall configuration of the device

[0049] refer to Figure 1 Taking a sedimentation tank 1 in a waterworks as an example, the sedimentation tank 1 is 30m long, 15m wide, and 5m deep, with inclined pipes at the bottom to enhance the sedimentation effect. According to the technical solution of this utility model, a longitudinal moving mechanism 3 and a transverse moving mechanism 6 are respectively installed on the four walls of the sedimentation tank 1.

[0050] • Two longitudinal tracks 3-1 are respectively installed on the two longitudinal walls of sedimentation tank 1, and a sliding track car 3-2 is installed on each longitudinal track 3-1 accordingly;

[0051] • Two transverse tracks 3-1 are respectively set on the two transverse walls of sedimentation tank 1. The structure of the transverse moving mechanism 6 is the same as that of the longitudinal moving mechanism 3. Correspondingly, a sliding track car 3-2 is installed on each transverse track 3-1.

[0052] refer to Figure 6-7The track carriage 3-2 of both the longitudinal moving mechanism 3 and the transverse moving mechanism 6 consists of a driving wheel 3-2-3, a driven wheel 3-2-2, a fixed plate 3-2-1, and a drive motor 3-2-4. The driving wheel 3-2-3 is connected to the drive motor 3-2-4 via its shaft, thereby driving the track carriage 3-2 to reciprocate along the track 3-1. Both ends of the track 3-1 are fixed to the corresponding walls of the sedimentation tank 1 using expansion bolts or embedded parts to ensure the stability and durability of the track.

[0053] 2. Floating platform and cable arrangement

[0054] refer to Figure 1-5 In this embodiment, the floating platform 2 adopts a structure of a disc-shaped body 2-1 plus a spherical counterweight 2-2. The body 2-1 is made of a polymer material such as high-density polyethylene (HDPE), which has a density less than water, ensuring that the floating platform has sufficient buoyancy. The counterweight 2-2 is made of a metal alloy, which has a density greater than water, and is fixed to the lower surface of the body 2-1 by bolts or welding. It is used to lower the center of gravity of the floating platform and improve the overall stability of the floating platform on the water surface.

[0055] The outer diameter of the main body 2-1 is approximately 1.2m, and the thickness is approximately 0.4m.

[0056] The radius of counterweight 2-2 is smaller than that of the main body 2-1, and its shape is a spherical cap, with its central axis aligned with that of the main body 2-1.

[0057] The outer edge of the floating platform 2 is machined with a transverse through hole 2-1-1 and a longitudinal through hole 2-1-2, which are mutually perpendicular and do not intersect, and are used to insert the transverse cable 5 and the longitudinal cable 4, respectively. In this embodiment:

[0058] • The two ends of the transverse cable 5 are fixedly connected to the railcars 3-2 of the two longitudinal moving mechanisms 3 respectively;

[0059] • The two ends of the longitudinal cable 4 are fixedly connected to the railcars 3-2 of the two transverse moving mechanisms 6 respectively.

[0060] In this way, when the railcar 3-2 moves on the longitudinal or transverse track, the pontoon 2 can be moved in the corresponding direction on the water surface by the transverse cable 5 and the longitudinal cable 4.

[0061] 3. Cleaning gun and main unit

[0062] refer to Figure 1-5In this embodiment, the operator performs inclined tube cleaning on the floating platform 2. To achieve efficient cleaning, a main unit 7 is installed outside the tank. The main unit 7 can be a high-pressure water pump or a power supply. The cleaning gun 8 can be a spray gun or an ultrasonic generator. If it is an ultrasonic generator, the high-pressure water pump is connected to the cleaning gun 8 on the floating platform 2 through a flexible high-pressure water pipe. The flexible high-pressure water pipe is slightly longer than the depth of the sedimentation tank and has good pressure resistance and bending resistance. If it is a power supply and an ultrasonic generator, they are connected through flexible cables.

[0063] When it is necessary to rinse the surface of the inclined tube, the operator picks up the cleaning gun 8 on the floating platform 2, starts the main unit 7, and the high-pressure water jet sprayed from the cleaning gun 8 can effectively rinse the inclined tube. Since the floating platform can move to any position directly above the inclined tube at the bottom of the pool, it can achieve large-area full-coverage cleaning and avoid the blind spots that exist in traditional cleaning methods.

[0064] 4. Floating platform movement and button control

[0065] refer to Figure 1-5 A handle 11 is vertically fixed at the center of the upper surface of the floating platform 2 body 2-1, allowing the operator to hold onto the handle and maintain balance. In addition, two lateral movement control buttons 10 and two longitudinal movement control buttons 9 are symmetrically distributed radially on the upper surface of the floating platform 2.

[0066] • Lateral movement control button 10: connected to the drive motor 3-2-4 of the track car 3-2 of the lateral movement mechanism 6, used to control the lateral movement of the floating platform in the horizontal direction;

[0067] • Longitudinal movement control button 9: Connected to the drive motor 3-2-4 of the track car 3-2 of the longitudinal movement mechanism 3, used to control the longitudinal movement of the floating platform in the horizontal direction.

[0068] During the cleaning process, if it is necessary to move to the central area of ​​the pool for rinsing, the operator presses the corresponding reset switch control button, and the corresponding track car 3-2 starts to move, which drives the cables 4 and 5 and the floating platform 2 to move smoothly in the expected direction. When the target position is reached, the button is released, the track car stops moving, and the floating platform 2 remains in that position, meeting the requirements for further precise rinsing of the inclined tube.

[0069] 5. Example of usage steps

[0070] (1) Preparation stage: Start the power supply of the drive motors of the longitudinal moving mechanism 3 and the transverse moving mechanism 6, and the power supply of the main unit 7; check whether the track car 3-2, the transverse cable, the longitudinal cable 4 and the floating platform 2 are in good condition;

[0071] (2) Personnel in position: After the operator enters the work platform above the sedimentation tank, he steps on the upper surface of the floating platform 2 and holds the handle 11 with both hands to stand firmly.

[0072] (3) Position movement: The operator selects the corresponding horizontal movement control button 10 or vertical movement control button 9 according to the required cleaning direction by stepping on it, so that the floating platform 2 moves smoothly above the target inclined tube, and then stops pressing the horizontal movement control button 10 or vertical movement control button 9.

[0073] (4) Flushing operation: Start the main unit 7 and use the handheld cleaning gun 8 to flush the inclined tube. If it is necessary to change the position, release the button and use the same method to move the floating platform 2 to the new position;

[0074] (5) Finishing work: After cleaning, turn off the main unit 7, move the floating platform 2 to a safe position close to the pool wall, and the operators leave the work area above the sedimentation tank; turn off the power to all motors and equipment.

[0075] 6. Effects and Advantages

[0076] (1) The setting of the floating platform 2 allows operators to work on the surface of the sedimentation tank without wading or stepping on the inclined tube, effectively protecting the inclined tube structure.

[0077] (2) The combination of the main body 2-1 and the spherical counterweight 2-2 gives the floating platform excellent balance and stability. Even if the operators and equipment have a certain weight, it is not easy to tilt or overturn.

[0078] (3) By linking the railcar 3-2 with the transverse cable 5 and the longitudinal cable 4, all-round positioning and cleaning can be achieved throughout the entire sedimentation tank, truly achieving no cleaning dead corners;

[0079] (4) The horizontal movement control button 10 and the vertical movement control button 9 are distributed symmetrically on the upper surface of the floating platform 2. The operator can easily move forward, backward, left and right by stepping on the buttons, which improves the cleaning efficiency.

[0080] (5) The handle 11 provides good operating support, and together with the stable floating platform structure and cable restraint, it makes the operation of the high-pressure water gun safer and more reliable.

[0081] In summary, this invention achieves full coverage and high-efficiency cleaning of the inclined tubes by setting up a track vehicle, cables, and a movable floating platform at the bottom of the sedimentation tank. Simultaneously, since it eliminates the need for manual stepping on the inclined tubes, it significantly extends their service life and avoids damage and secondary pollution caused by foot traffic.

[0082] All aspects not detailed in this utility model are well-known to those skilled in the art. Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and not to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
