Description

Technical Field

[0001] The utility model relates to the technical field of sewage pool cover plates, in particular to an arched cover plate for a sewage pool. Background Art

[0002] With the development of economy and the worsening of haze weather, environmental protection has received more and more attention, and the country's efforts to govern the environment have been strengthened year by year. During the treatment process of sewage treatment plants, harmful gases are directly emitted into the air, causing impacts on the environment and human health.

[0003] At present, sewage treatment pools use fiberglass covers to seal and collect sewage pools. However, fiberglass covers are very easy to age under sunlight and have low corrosion resistance. In addition, when the existing linear covers are in a large-span state, they will affect the sealing of harmful gases in the sewage pool due to low strength, low rigidity, and short service life.

[0004] For example, Chinese patent CN212224187U discloses an arched cover for a sewage pool. By changing the overall shape of the cover and its cross-sectional shape, the overall shape of the linear cover is improved into an arched shape, and the cross-sectional shape is improved into a corrugated shape formed by connecting three or six wave arcs. This increases the overall strength of the cover, enables it to be made into a large-span form, and at the same time can extend its service life and reduce the impact of its own low performance on the sealing of harmful gases in the sewage pool.

[0005] However, the device cannot adjust the width of the cover according to the width of the sewage pool during use, and its practicality is low.

[0006] For this reason we urgently need to provide a kind of sewage pool arch cover. Utility Model Content

[0007] The utility model aims to provide an arched cover for a sewage pool, so as to solve the problem of low practicality in that the width of the cover cannot be adjusted according to the width of the sewage pool during use as mentioned in the background technology.

[0008] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: an arched cover plate for a sewage pool, comprising an outer cover plate, wherein an auxiliary device is arranged on the inner side of the outer cover plate.

[0009] The auxiliary device comprises an adjusting unit, a cleaning unit and an installing unit. The adjusting unit is arranged on the left and right sides of the outer cover plate, the cleaning unit is arranged at the bottom of the outer cover plate, and the installing unit is arranged on the left and right sides of the outer cover plate.

[0010] The adjustment unit includes an inner cover plate, a fixed plate, a spring, a disc, a clamping rod and a pull rod. The inner cover plate is slidably connected to the inside of the outer cover plate. The fixed plate is fixedly installed on the top of the left and right sides of the outer cover plate. One end of the spring is fixedly installed on the top of the inside of the fixed plate. The disc is fixedly installed on the bottom of the spring. The clamping rod is fixedly installed on the bottom of the disc. The pull rod is fixedly installed on the top of the disc and extends above the fixed plate.

[0011] Preferably, the cleaning unit comprises a mounting rod, a fixing block and a scraper, wherein the mounting rod is fixedly mounted on the lower inner end of the outer cover plate, the fixing block is fixedly mounted on the left and right ends of the outer side of the mounting rod, and the scraper is mounted on the top of the fixing block.

[0012] Preferably, the mounting unit comprises bolts and sealing gaskets, the bolts are mounted on the left and right sides of the inner part of the outer cover plate and the inner cover plate, and the sealing gaskets are mounted on the left and right sides of the bottom of the outer cover plate.

[0013] Preferably, mounting holes are provided on the upper surfaces of the left and right sides of the outer cover plate and the inner cover plate, and the size of the mounting holes is equal to the diameter of the bolts. The bolts penetrate the mounting holes and are connected to the reserved threaded holes on the top of the sewage pool, thereby facilitating the fixing of the outer cover plate and the inner cover plate on the top of the sewage pool.

[0014] Preferably, the diameter of the clamping rod is equal to the diameter of the mounting hole, a connecting groove is opened inside the outer cover plate, and the inner cover plate is slidably connected inside the connecting groove. By pulling the inner cover plate to slide along the inside of the outer cover plate, the width of the inner cover plate and the outer cover plate is made the same as the width of the sewage pool, so that the cover plate can adapt to sewage pools of different widths. At the same time, the clamping rod penetrates the mounting holes opened in the outer cover plate and the inner cover plate, thereby fixing the outer cover plate and the inner cover plate.

[0015] Preferably, the top of the scraper is in contact with the lower surface of the inner cover plate, and when the inner cover plate is stored inside the outer cover plate, the scraper is used to scrape off the stains on the lower surface of the inner cover plate to prevent the stains from clogging the connecting grooves of the outer cover plate.

[0016] Preferably, the scraper and the fixing block are connected by Velcro, and when too many impurities are attached to the surface of the scraper, the scraper can be removed to facilitate cleaning.

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

[0018] 1. The sewage pool uses an arched cover plate. By setting an adjustment unit, the pull rod is pulled upward to drive the disc to move upward to compress the spring, and at the same time, the clamping rod is moved out of the mounting holes provided in the outer cover plate and the inner cover plate, and then the inner cover plate is pulled outward until the distance between the outer cover plate and the inner cover plate is equal to the width of the sewage pool, and then the pull rod is released, and the clamping rod is pushed through the mounting holes provided in the outer cover plate and the inner cover plate under the action of the spring, thereby fixing the outer cover plate and the inner cover plate, making it easy to adjust the cover plate width according to the width of the sewage pool, thereby improving the practicability of the device, and solving the problem of low practicability in the background technology that the width of the cover plate cannot be adjusted according to the width of the sewage pool during use.

[0019] 2. The sewage pool uses an arched cover plate. By setting a cleaning unit, when the inner cover plate is stored inside the outer cover plate, the stains on the lower surface of the inner cover plate are scraped off by a scraper to prevent the stains from clogging the connecting grooves opened on the outer cover plate.
