Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a sliding and stretchable platform for disassembling aeration heads in an aerobic wastewater treatment tank. Background Technology

[0002] Aerobic wastewater treatment tanks are wastewater treatment units that utilize aerobic microorganisms to degrade organic pollutants in wastewater. They are one of the facilities in urban and industrial wastewater treatment processes that achieve efficient degradation of organic matter.

[0003] In existing technologies, aerobic tanks are filled with oxygen through an aeration system. The oxygen is transported through aeration branch pipes and finally injected into the aerobic tank from the aeration heads, providing an aerobic environment for microbial metabolism. As the usage time increases, the aeration heads are immersed in sewage for longer periods, and impurities in the sewage may clog the aeration heads, potentially causing damage. Therefore, it is necessary to disassemble, inspect, or replace the aeration heads regularly.

[0004] However, in existing aeration head dismantling operations, workers often need to rely on temporary scaffolding or floats to carry out the work. Scaffolding is time-consuming to set up, lacks flexibility, and cannot adapt to aeration pipe layouts with varying spacing; floats are prone to swaying due to sewage buoyancy, posing safety hazards, and are difficult to accurately locate the aeration head to be repaired, resulting in low maintenance efficiency and high operational risks. Therefore, this utility model proposes a sliding, stretchable platform for dismantling aeration heads in aerobic wastewater treatment tanks to effectively solve the above-mentioned drawbacks. Utility Model Content

[0005] The purpose of this invention is to provide a sliding and stretchable platform for disassembling aeration heads in aerobic tanks of wastewater treatment plants, in order to solve the problems mentioned in the background art.

[0006] This utility model is achieved through the following technical solution: a sliding and stretchable platform for disassembling aeration heads in an aerobic tank of wastewater treatment, comprising: The platform body has a rectangular frame structure and is distributed horizontally, with openings on both the left and right sides; The extension platform consists of two platforms, which are symmetrically distributed on the left and right sides and can be extended and nested inside the platform body. The two extension platforms are slidably connected to the left and right sides of the platform body, respectively. The suspension assembly consists of four sets, which are symmetrically distributed in pairs on the top of the outer part of the two extension platforms. The two sets of suspension assemblies on the same extension platform are symmetrically distributed front and back at the ends of the extension platform on the top surface of the outer part of the platform body. The suspension assembly is used to suspend on the aeration pipe and can move along the extension direction of the aeration pipe.

[0007] Optionally, the platform body has a number of positioning holes equidistantly spaced along its length on both the front and rear sides, and the extension platform has a number of positioning grooves on the side facing the positioning holes. The positioning holes and positioning grooves correspond one-to-one, and positioning pins are inserted into the positioning holes and positioning grooves to fix the extension platform.

[0008] Optionally, the suspension assembly includes a fixed bracket that is vertically fixedly connected to the top surface of the extension platform. The fixed bracket is hollow inside and has no top cover. A suspension bracket is slidably connected inside the fixed bracket along the vertical direction. The fixed bracket and the suspension bracket are fixed together by a pin.

[0009] Optionally, the top of the suspension bracket extends outward from the fixed bracket and is bent into a U-shaped suspension part away from the platform body. The suspension part is suspended on the aeration pipe. The inner side of the suspension part on the suspension bracket is provided with a pulley that rotates through a pivot. The pulleys in the four sets of suspension components are placed on two parallel adjacent aeration pipes.

[0010] Optionally, a rotating bracket is rotatably mounted on the rotating shaft. One end of the rotating bracket, away from the rotating shaft, extends to the circumferential side of the pulley and is fixedly connected to an inclined plug. The inclined plug is used to abut against the circumferential side of the pulley and the aeration pipe to fix the pulley.

[0011] Optionally, protective rods are fixedly installed between the two fixed supports near the front side of the platform body and between the two fixed supports near the rear side of the platform body. The two protective rods are distributed along the width direction of the platform body and are arranged in parallel.

[0012] Compared with the prior art, this utility model provides a sliding and stretchable platform for disassembling aeration heads in an aerobic tank of wastewater treatment, which has the following advantages: 1. In this utility model, by setting retractable extension platforms on both sides of the platform body, the width of the entire platform can be freely adjusted to adapt to the layout of aeration pipes with different spacing. By using a suspension component that can be adjusted and extended vertically, the height of the entire platform can be freely adjusted to adapt to the layout of aeration pipes with different heights. It is not only widely adaptable, but also quick and convenient to build. 2. This utility model makes the entire platform easier to move by setting pulleys on the suspension assembly and making the pulleys roll on the aeration pipe. Then, by manually pulling the rope, the platform can be moved along the extension direction of the aeration pipe, which makes it easy for the staff to adjust the position of the platform. With the help of the inclined pad, the platform position is fixed, so that the staff can accurately stop the platform at the aeration head that needs to be inspected and disassembled, thus facilitating the disassembly operation.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 - Figure 3 A sliding and stretchable platform for disassembling aeration heads in an aerobic tank of wastewater treatment includes a platform body 1, which has a rectangular frame structure and is distributed horizontally. Both sides of the platform body 1 are open, and extension platforms 2 are nested within each of these openings. The two extension platforms 2 are slidably connected to the left and right sides of the platform body 1 along its width, respectively. One side of each extension platform 2 can slide to the outside of the platform body 1 to increase its width. Therefore, the platform body 1 and the extension platforms 2 can be combined to form a platform for workers to stand on, and the width of the platform can be freely adjusted to accommodate aeration pipe layouts with different spacing.

[0017] The extension platform 2 is located inside the platform body 1 at a height greater than the width of the side opening of the platform body 1. The side wall of the extension platform 2 is slidably connected to the side wall of the platform body 1 so that the side of the extension platform 2 located inside the platform body 1 cannot slide to the outside of the platform body 1, thereby improving the stability of the platform.

[0018] Furthermore, the platform body 1 has a number of positioning holes 11 equidistantly spaced along its length on both the front and rear sides, and the extension platform 2 has a number of positioning grooves 21 on the side facing the positioning holes 11. The number of positioning holes 11 and the number of positioning grooves 21 correspond one to one, and positioning pins 22 are inserted into the positioning holes 11 and the positioning grooves 21 to fix the extension platform 2.

[0019] The positioning hole 11 has a diameter of 8-10mm, and the positioning pin 22 can be connected by bolts or stainless steel spring pins. The diameter of the positioning pin 22 is compatible with the diameter of the positioning hole 11 and the positioning groove 21 so that the operator can adjust the extension width of the extension platform 2.

[0020] In this embodiment, two sets of suspension components 3 are fixedly installed on the top of the outer portion of the two extension platforms 2. The two sets of suspension components 3 on the same extension platform 2 are symmetrically distributed front and back at the ends of the extension platform 2 located on the top surface of the outer portion of the platform body 1, that is, four sets of suspension components 3 are distributed at the four ends of the two extension platforms 2 on the outer portion of the platform body 1. The four symmetrically distributed sets of suspension components 3 are suspended on two parallel aeration pipes, so that the platform can be stably suspended below the aeration pipes.

[0021] Specifically, the suspension assembly 3 includes a fixed bracket 31 that is vertically fixedly connected to the top surface of the extension platform 2. The fixed bracket 31 is hollow inside and has no top cover. A suspension bracket 32 ​​is slidably connected vertically inside the fixed bracket 31. The top of the suspension bracket 32 ​​is located outside the fixed bracket 31. The fixed bracket 31 and the suspension bracket 32 ​​are fixed together by a pin 33 so that the suspension bracket 32 ​​can be adjusted to change the length of the suspension bracket 31, thereby changing the overall height of the suspension assembly 3. After being fixed with the pin 33, the height of the platform can be adapted to the layout of aeration pipes at different heights.

[0022] The width of the end of the suspension bracket 32 ​​located inside the fixed bracket 31 is greater than the width of the opening at the top of the fixed bracket 31, so that the bottom end of the suspension bracket 32 ​​cannot slide to the outside of the fixed bracket 31, thus preventing the suspension bracket 32 ​​and the fixed bracket 31 from separating and causing the platform to fall.

[0023] On the other hand, limit holes are provided on the side walls of both the fixed bracket 31 and the suspension bracket 32, and the limit holes are used for the insertion of the pin 33 to fix the height of the suspension bracket 32.

[0024] It should be noted that the top of the suspension bracket 32 ​​extends outward from the fixed bracket 31 and is bent into a U-shaped suspension part on the side away from the platform body 1. The suspension part is suspended from the aeration pipe. A pulley 35 is rotatably mounted on the inner side of the suspension part on the suspension bracket 32 ​​via a rotating shaft 34. The pulleys 35 in the four sets of suspension components 3 are placed on two parallel adjacent aeration pipes. Therefore, when the operator needs to move the platform, the pulleys 35 can roll on the aeration pipe, making the movement of the platform more convenient and labor-saving.

[0025] The rotating shaft 34 is horizontally distributed along the width of the platform body 1, and the left and right ends of the rotating shaft 34 are fixedly connected to the inner side of the suspension part at the top of the suspension bracket 32. The pulley 35 is rotated and fitted on the outside of the rotating shaft 34. The outer surface of the pulley 35 is made of soft materials such as rubber to reduce wear on the aeration pipe.

[0026] In order to prevent the pulley 35 from rolling when the platform is in a fixed state, a rotating bracket 36 is rotatably sleeved on the rotating shaft 34 in this application. The end of the rotating bracket 36 away from the rotating shaft 34 extends to the circumferential side of the pulley 35 and is fixedly connected with a slanted pad 37. The slanted pad 37 is used to abut against the circumferential side of the pulley 35 and the aeration pipe to fix the pulley 35.

[0027] When the platform moves to the location of the aeration head that needs to be inspected and disassembled, the inclined pads 37 are manually controlled to rotate around the shaft 34, causing them to be inserted between the pulleys 35 and the aeration pipe, thus blocking the rotation of the pulleys 35. When the inclined pads 37 on different pulleys 35 limit the movement of the pulleys 35, they all rotate around their corresponding shafts 34 toward the center of the platform body 1. This ensures that after the four inclined pads 37 have completed their limiting of the corresponding pulleys 35, the four pulleys 35 cannot roll forward or backward, making the platform more stable.

[0028] Furthermore, the contact surfaces of the inclined pad 37 with the pulley 35 and the aeration pipe are all made of rubber to increase friction; the rotating bracket 36 and the rotating shaft 34 are rotatably connected by a damping bearing so that the inclined pad 37 can remain stable without external force and will not cause the rotating bracket 36 to rotate around the rotating shaft 34.

[0029] In this embodiment, protective rods 4 are fixedly installed between the two fixed supports 31 near the front side of the platform body 1 and between the two fixed supports 31 near the rear side of the platform body 1. The two protective rods 4 are distributed and arranged parallel to each other along the width direction of the platform body 1 to improve the safety of the platform. The protective rods 4 are telescopic rod structures so that the protective rods 4 will not obstruct the sliding of the two extended platforms 2 when they slide.

[0030] It should be noted that anti-slip treads 5 are fixedly laid on the top surface of both the main platform 1 and the extended platform 2. The top surface of the anti-slip treads 5 has anti-slip texture to further improve the safety of the platform and prevent workers from slipping.

[0031] Furthermore, there are two ropes 6 distributed parallel to the aeration pipes between the two aeration pipes. The two ends of the aeration pipes are fixed to the mounting brackets (not shown in the attached drawings). The two ends of the ropes 6 are also fixed to the mounting brackets so that the workers on the platform can control the movement of the platform by pulling the ropes 6 to make the pulleys 35 roll on the aeration pipes.

[0032] The working principle and usage process of this utility model are as follows: First, when building the platform, pull the two extension platforms 2 outward from the left and right sides of the main platform 1 to match the overall width of the platform with the distance between the two aeration pipes. After fixing the extension platforms 2 with positioning pins 22, adjust the length of the suspension bracket 32 ​​extending from the fixed bracket 31 so that the pulley 35 can be placed on the aeration pipe. Fix the suspension bracket 32 ​​with pins 33. At this point, the platform is built. Move the platform along the distribution direction of the aeration pipes to the position of the aeration head that needs to be inspected and disassembled by pulling the rope 6. Then rotate the inclined stopper 37 to limit the pulley 35, thereby fixing the position of the platform and enabling the workers to disassemble and assemble the aeration heads.
