Description

Technical Field

[0001] The utility model belongs to the technical field of covers for sewage pools, and particularly relates to a movable cover for a sewage pool. Background Art

[0002] In the current industrial production process, industrial wastewater is inevitably generated. Industrial wastewater usually contains various forms of industrial waste and polluted liquids generated during the production process. Therefore, it is necessary to collect the polluted liquids through sewage pools. During the process of storing industrial wastewater, the industrial wastewater slowly emits toxic, harmful and irritating gases. Therefore, a cover is usually provided on the top of the sewage pool to prevent the emission of toxic and harmful gases. At present, the common sewage pool covers are mainly of two types, one is a fiberglass arch cover, and the other is a flat cover.

[0003] Chinese utility model patent CN221319417U discloses a fiberglass cover device for deodorization and isolation, including: a plurality of mutually connected cover bodies, and further including a splicing component for connecting two adjacent cover bodies. The cover body includes an arc portion and extension portions provided at both ends of the arc portion. An odor collection component is provided on the arc portion. Both sides of the cover body are bent upward and extended to form splicing portions, and a splicing groove is opened at the top of the splicing portion; the splicing component includes an arc plate matching the radian of the top of the splicing portion. Horizontal plates are fixedly provided at both ends of the arc plate. Two splicing blocks are arranged at intervals at the bottom of the arc plate and the horizontal plate. The splicing blocks match the splicing grooves, and the two splicing blocks are respectively inserted into the splicing grooves on two adjacent cover bodies.

[0004] In the above technical solution, when the sewage pool needs to be cleaned and maintained, it is necessary to unscrew the bolts to completely disassemble the cover, which is too troublesome and increases the labor cost of the staff. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a movable cover for a sewage pool aiming at the above existing technical problems, so that when the sewage pool needs to be cleaned or maintained, the cover can be easily moved without complete disassembly, which not only saves time and labor, but also reduces equipment wear and damage caused by frequent disassembly and assembly.

[0006] In view of this, the utility model provides a movable cover for a sewage pool, which is characterized in that it includes: a high movable cover, a low movable cover and two symmetrically distributed slide rails. Sliding components are provided on the inner sides of the high movable cover and the low movable cover. The sliding component includes: a pulley installation groove, and a pulley is rotatably connected in the pulley installation groove. The high movable cover and the low movable cover slide on the slide rails through the pulleys.

[0007] In this technical solution, the high movable cover plate and the low movable cover plate move left and right on the slide rail through pulleys, so that the cover plate can easily cover or expose the sewage pool when needed, facilitating various operations, thereby reducing equipment wear caused by frequent disassembly and assembly, and reducing the operating difficulty of staff.

[0008] In the above technical solution, further, both sides of the upper surface of the slide rail are bent inward in both directions, and the two sides are divided into a high-end part and a low-end part, and the high-end part and the low-end part are used to place a high movable cover plate and a low movable cover plate respectively.

[0009] In the above technical solution, further, the sliding component on the inner side of the high movable cover plate slides on the high-grade portion, and the sliding component on the inner side of the low movable cover plate slides on the low-grade portion.

[0010] The bidirectional bending design on the upper surface of the slide rail is to accommodate the thickness difference between the high movable cover plate and the low movable cover plate, ensuring that the two can slide smoothly in their respective gears without interfering with each other. The high-grade portion is used to place the thicker high movable cover plate, while the low-grade portion is used to place the thinner low movable cover plate. This staggered design allows the two covers to slide independently on the same slide rail without affecting each other.

[0011] In the above technical solution, further, a sealing arch piece is provided on the inner side of the high movable cover plate, and the sealing arch piece is used to seal the gap between the high movable cover plate and the low movable cover plate.

[0012] In this technical solution, when the high movable cover plate and the low movable cover plate slide on the slide rail through the pulley, the sealing arch plate moves accordingly to maintain a dynamic seal with the low movable cover plate, thereby preventing exhaust gas from overflowing from the gap at the connection between the high movable cover plate and the low movable cover plate.

[0013] In the above technical solution, further, a part of the high movable cover plate and the low movable cover plate located in the slide rail is connected to a glass fiber reinforced plastic plate through rivets.

[0014] In this technical solution, a glass fiber reinforced plastic plate is installed later and connected to the high movable cover plate and the low movable cover plate by rivets respectively. When the movable plate slides, it jumps to prevent the pulley from deviating from the guide rail.

[0015] In the above technical solution, further, a plurality of mounting holes are evenly arranged between the high-end portion and the low-end portion, and the mounting holes penetrate the slide rail.

[0016] In the above technical solution, further, a plurality of reinforcing ribs are provided on the upper surfaces of the high movable cover plate and the low movable cover plate.

[0017] In this technical solution, the design of the reinforcing ribs enables the cover plate to evenly disperse the force to the entire surface of the cover plate when bearing the load from above, reducing deformation or damage caused by excessive local stress.

[0018] The beneficial effects of the present utility model are as follows:

[0019] 1. The high movable cover plate and the low movable cover plate move left and right on the slide rail through pulleys, enabling the cover plate to easily cover or expose the sewage pool when needed, facilitating various operations, thereby reducing equipment wear caused by frequent disassembly and assembly and reducing the operation difficulty of the staff.

[0020] 2. By installing fiberglass plates later and riveting them to the high movable cover plate and the low movable cover plate respectively, when the movable plate slides and bounces, it prevents the pulley from deviating from the guide rail. Description of the Drawings

[0031] Embodiment 1:

[0032] As Figures 1 - 3 shown, this embodiment provides a movable cover plate for a sewage tank, which includes: a high movable cover plate 1, a low movable cover plate 2, and two symmetrically distributed slide rails 3. Sliding components 6 are provided on the inner sides of the high movable cover plate 1 and the low movable cover plate 2. The sliding component 6 includes: a pulley installation groove 601, and a pulley 602 is rotatably connected in the pulley installation groove 601. The high movable cover plate 1 and the low movable cover plate 2 slide on the slide rail 3 through the pulley 602. The high movable cover plate 1 and the low movable cover plate 2 move left and right on the slide rail 3 through the pulley 602, so that the cover plate can easily cover or expose the sewage tank when needed, facilitating various operations, thereby reducing equipment wear caused by frequent disassembly and assembly, and reducing the operation difficulty of the staff.

[0033] Furthermore, both sides of the upper surface of the slide rail 3 are bent inward in a two-way manner, and are divided into a high-grade part 8 and a low-grade part 9 on both sides. The high-grade part 8 and the low-grade part 9 are respectively used to place the high movable cover plate 1 and the low movable cover plate 2. The sliding component 6 on the inner side of the high movable cover plate 1 slides on the high-grade part 8, and the sliding component 6 on the inner side of the low movable cover plate 2 slides on the low-grade part 9. The two-way bending design of the upper surface of the slide rail 3 is to adapt to the thickness difference between the high movable cover plate 1 and the low movable cover plate 2, ensuring that the two can slide smoothly in their respective parts without interfering with each other. The high-grade part 8 is used to place the thicker high movable cover plate 1, while the low-grade part 9 is used to place the thinner low movable cover plate 2. This design with high and low staggering enables the two cover plates to slide independently on the same slide rail 3 without affecting each other.

[0034] Further, a sealing arch piece 5 is provided on the inner side of the high movable cover plate 1. The sealing arch piece 5 is used to seal the gap between the high movable cover plate 1 and the low movable cover plate 2. When the high movable cover plate 1 and the low movable cover plate 2 slide on the slide rail 3 through the pulley 602, the sealing arch piece 5 moves accordingly to maintain dynamic sealing with the low movable cover plate 2, thereby preventing waste gas from overflowing from the gap at the connection between the high movable cover plate 1 and the low movable cover plate 2.

[0035] Further, a fiberglass plate 7 is connected to a part of the high movable cover plate 1 and the low movable cover plate 2 located inside the slide rail 3 by rivets. By installing the fiberglass plate 7 later and connecting it to the high movable cover plate 1 and the low movable cover plate 2 by rivets respectively, when the movable plate slides and bounces, it prevents the pulley 602 from deviating from the guide rail.

[0036] Further, a number of mounting holes 10 are evenly provided between the high-grade part 8 and the bottom-grade part. The mounting holes 10 penetrate through the slide rail 3. The two slide rails 3 are respectively fixed on both sides of the sewage tank through the mounting holes 10.

[0037] Further, a number of reinforcing ribs 4 are provided on the upper surfaces of the high movable cover plate 1 and the low movable cover plate 2. The design of the reinforcing ribs 4 enables the cover plate to evenly disperse the force to the entire surface of the cover plate when bearing the load from above, reducing deformation or damage caused by excessive local stress.

[0038] The embodiments of the present application have been described above in conjunction with the accompanying drawings. Without conflict, the embodiments and the features in the embodiments in the present application can be combined with each other. The present application is not limited to the above specific embodiments. The above specific embodiments are merely illustrative and not restrictive. Under the inspiration of the present application, those of ordinary skill in the art can also make many forms without departing from the purpose of the present application and the scope protected by the claims, and all belong to the protection scope of the present application.
