Description

Technical Field

[0001] This utility model belongs to the technical field of construction tools, specifically relating to a water tank lifting plate for replacing aeration heads in aerobic tanks of sewage treatment. Background Technology

[0002] The wastewater treatment industry widely adopts aerobic tank biological treatment processes, in which liftable aerators are key equipment requiring regular maintenance or replacement. However, in existing technologies, aerators are typically installed approximately 5 meters underwater, with their connection flanges located 60 cm above the water surface. This necessitates operators performing replacements near the water surface, presenting two major problems: first, the narrow operating space and proximity to the water surface increase the risk of slipping or falling, posing significant safety hazards; second, the complex connection structure between the aerator and the air pipeline makes it difficult to stably attach conventional tools, resulting in low replacement efficiency. Furthermore, traditional support platforms lack anti-slip, drainage, and tool storage functions, further exacerbating operational inconvenience. Therefore, a specialized tool that combines safety, stability, and integrated functions is urgently needed to address these technical pain points. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a water tank hanging plate for replacing aeration heads in aerobic tanks of sewage treatment. Through integrated design, it significantly improves the safety, efficiency and environmental adaptability of replacing aeration heads in aerobic tanks of sewage treatment. It solves the core problems of traditional replacement tools, such as high safety hazards, cumbersome operation and poor adaptability. It is suitable for the high-efficiency maintenance needs of sewage treatment plants in continuous production scenarios.

[0004] This utility model is achieved using the following technical solution:

[0005] The aforementioned water tank hanging plate for replacing aeration heads in aerobic tanks of wastewater treatment includes a support frame, a support plate fixed to the upper surface of the support frame by bolts, and telescopic rods connected to the four corners of the support frame by positioning hinges. The telescopic rods are multi-section sleeve structures with hooks at the ends. Protective frames are also symmetrically welded around the support frame.

[0006] The support frame is a rectangular frame welded from angle steel, with 2-3 carbon steel pipes fixed horizontally inside the frame.

[0007] The protective frame is equipped with a tool hanging basket.

[0008] The telescopic rod sleeve connection is equipped with a locking device.

[0009] The support plate is made of bamboo plywood with a non-slip rubber layer on its surface.

[0010] The support plate is also provided with drainage holes evenly spaced.

[0011] The working principle of the water tank lifting plate used for replacing aeration heads in the aerobic tank of sewage treatment is as follows:

[0012] The support frame is made of angle steel welded into a rectangular frame. Two to three carbon steel pipes are horizontally fixed inside the frame to enhance the overall load-bearing capacity. A protective frame is welded around the frame.

[0013] The support plate is fixed to the upper surface of the support frame with bolts. Bamboo plywood is used as the base material, and the surface is covered with an anti-slip rubber layer to increase friction. Drainage holes are evenly opened on the support plate to quickly drain accumulated water and avoid water pressure from hindering the lowering of the platform.

[0014] The telescopic rod is connected to the four corners of the support frame via positioning hinges. The telescopic rod has a multi-section sleeve structure, and the sleeve connection is equipped with a locking device. The length can be adjusted and fixed. The end is equipped with a hook for attaching to the air pipeline, so that the operator can work in a stable position away from the water surface.

[0015] The protective frame is equipped with tool baskets to store replacement tools such as wrenches and bolts, reducing the time spent retrieving parts; the protective frame and the support frame are welded together to ensure structural stability.

[0016] During operation, the length and angle of the telescopic rod are adjusted to match the spacing of the air pipelines in different aerobic tanks, and a stable support is formed after locking. The operator stands on the anti-slip support plate, uses the tool basket to retrieve tools, and drains the accumulated water in time through the drain hole to achieve rapid replacement of the aeration head.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] The water tank lifting platform for replacing aeration heads in aerobic tanks of wastewater treatment, as described in this utility model, features a scientifically designed structure, high functional integration, and strong practicality. This platform can quickly adapt to air pipelines and operating spaces of different sizes. It also employs a stable frame structure with adjustable telescopic support components to adapt to the working environment of aerobic tanks of different specifications. Operators can work on a stable platform away from the water surface, significantly reducing the risk of slipping. Its anti-slip drainage design effectively copes with the complex environment inside the tank, preventing water accumulation from interfering with operations. The tool storage and structural locking functions further simplify the operation process, reduce manual back-and-forth movement and adjustment time, and significantly improve the safety and convenience of operators. This device effectively shortens the replacement period for aeration heads, reduces labor intensity and operational risks, and combines high efficiency and safety. It solves the core problems of traditional replacement tools, such as high safety hazards, cumbersome operation, and poor adaptability. It is suitable for the high-efficiency maintenance needs of continuous production scenarios in wastewater treatment plants and has significant application value. Attached Figure Description

[0021] To make the objectives and technical solutions of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] Example 1

[0023] like Figure 1 As shown, the water tank hanging plate for replacing aeration heads in the aerobic tank of sewage treatment includes a support frame 1. A support plate 2 is fixed to the upper surface of the support frame 1 by bolts. The four corners of the support frame 1 are connected to telescopic rods 4 by positioning hinges 3. The telescopic rods 4 are multi-section sleeve structures with hooks 5 at the ends. Protective frames 6 are also symmetrically welded around the support frame 1.

[0024] The support frame 1 is a rectangular frame welded from angle steel, and two carbon steel pipes 7 are fixed horizontally inside the frame.

[0025] The protective frame 6 is equipped with a tool hanging basket 8.

[0026] The telescopic rod 4 is equipped with a locking device 9 at the sleeve connection.

[0027] The support plate 2 is made of bamboo plywood, and the surface is provided with an anti-slip rubber layer 10.

[0028] The support plate 2 is also provided with drainage holes 11 evenly spaced.

[0029] The specific steps for using it are as follows:

[0030] First, move the suspended platform to the target position above the aerobic tank. Based on the distribution and spacing of the air lines within the tank, flexibly adjust the unfolding angle of the four corner telescopic rods 4 using the positioning hinges 3. Then, utilize the multi-section sleeve structure to adjust the length of the telescopic rods 4, ensuring that the hooks 5 at their ends can accurately engage with the corresponding air lines. After adjustment, fix the length of the telescopic rods 4 using the locking device 9 at the sleeve connection, forming a stable and reliable support system to ensure that the entire suspended platform is stably suspended above the tank surface.

[0031] Operators safely climb over the protective frame 6 onto the support plate 2. The anti-slip rubber layer 10 on the surface of the support plate 2 effectively enhances friction and prevents personnel from slipping. During operation, the evenly distributed drainage holes 11 on the support plate 2 can promptly drain accumulated water, preventing water accumulation from affecting operations or increasing the load on the hoisting platform. Operators can quickly access wrenches, bolts, and other replacement tools through the tool basket 8 welded to the protective frame 6, eliminating the need for frequent trips to retrieve parts and significantly improving work efficiency. After replacement, operators detach from the support plate 2, retract the hoisting platform, and move it to the next work point, achieving an efficient and safe aerator head replacement process.
