Description

TECHNICAL FIELD

[0001] The utility model relates to a biological pool covering device. BACKGROUND

[0002] Biological pools (such as sewage treatment pools, fermentation pools, etc.) are generally provided with a cover plate device for covering the upper port. The main function of the cover plate device is to seal the pool body, prevent odor from spreading, protect the environment in the pool, and improve the safety of operation. The traditional cover plate has the following defects: first, it is mostly made of metal or concrete materials, which are easy to be corroded, especially in the humid and acidic and alkaline environment of the biological pool, and have a short service life. Second, the sealing performance is poor, and it is difficult to effectively prevent the leakage of gases (odor, fermentation gas) in the pool, resulting in environmental pollution and health risks to operators. Third, it needs to be frequently maintained and replaced, increasing the operating cost. Fourth, the biological pool cover plate needs to be frequently opened to check the liquid level and aeration conditions. Due to the lack of protection mechanism in the traditional cover plate, there is a risk of cover plate falling off and personnel falling when the cover plate is opened.

[0003] The Chinese utility model with the authorized announcement number CN217972728U discloses "a biochemical pool cover plate with a water scraping device". Under the premise of not opening the cover plate, ensuring the sealing performance of the biochemical pool, and avoiding gas leakage, the water scraping mechanism, the mounting mechanism, and the driving mechanism are cooperated to solve the problem of water droplets attached to the surface of the main plate, which facilitates personnel to clearly observe the internal conditions of the biochemical pool through the transparent main plate. Although this patent basically solves the sealing problem and safety hazard problem, the water scraping mechanism has the defects of complex structure and high maintenance cost. In addition, the water scraping mechanism only acts on the lower side of the transparent main plate, and when the upper side of the main plate is contaminated or has water droplets, it will affect the clarity of the observation of the internal conditions of the biochemical pool. UTILITY MODEL CONTENT

[0004] The technical problem to be solved by the utility model is to provide a biological pool covering device with an observation window, first, to more clearly observe the operation of the equipment and facilities in the pool under the premise of ensuring safety; second, to further improve the sealing performance, carrying capacity, corrosion resistance, and lightweight degree of the cover plate.

[0010] The utility model has the following beneficial effects:

[0011] Firstly, the fall arrest net of the utility model has the function of preventing personnel from falling into the biological pool, thereby ensuring the safety of the operator; on this basis, after the tempered glass cover plate is moved above the galvanized steel cover plate along the track, the mouth cover plate is partially opened, the fall arrest net is exposed, and the operating conditions of the equipment and facilities in the pool, including the liquid level and the aeration condition, can be clearly seen through the fall arrest net; when the inspection operation is completed or the maintenance is completed, the driving motor is reversely operated, the tempered glass cover plate is reset, and the overall structure returns to the closed state.

[0012] Secondly, under the closed state, the port of the biological pool is well sealed by the tempered glass cover plate and the galvanized steel cover plate, thereby effectively reducing the diffusion of waste gas, and the cover plate has the characteristics of large bearing capacity, strong corrosion resistance and high lightweight degree; the biological pool covering device of the utility model does not need to be frequently maintained and replaced, is convenient and labor-saving to operate, and is safe and reliable.

[0017] The embodiment of the present application will be described in detail below in combination with the drawings and examples.

[0018] As Figure 1 , Figure 2 and Figure 3 , the embodiment of the present application comprises a concrete foundation platform 8 arranged around the pool mouth of a biological pool. The embodiment further comprises an anti-falling net 4 connected with the concrete foundation platform 8. A frame 5 is fixedly installed on the upper side of the concrete foundation platform 8, and the frame 5 has a pair of oppositely arranged long side frames and a pair of oppositely arranged short side frames, which enclose a rectangle.

[0019] A rectangular galvanized steel cover plate 3 is inlaidly installed in the frame 5. One side of the galvanized steel cover plate 3 (left side in the figure) is inlaidly installed on one short side frame of the frame 5, and the side opposite to the one side has a viewing window gap with the other short side frame of the frame 5. The other two sides of the galvanized steel cover plate 3 are inlaidly installed on the two long side frames of the frame 5 respectively. One track 1 is installed on each of the two long side frames. The embodiment further comprises a toughened glass cover plate 2 for blocking the viewing window gap and being rectangular. Two groups of track wheels 7 (one group in front and one group in back in the figure, and each group has at least two track wheels) running on the track 1 are installed on the lower side of the toughened glass cover plate 2. Figure 1 Figure 1 Specifically, the wheel shafts of the track wheels 7 are installed on the wheel carriers 11 through bearings 9, and the wheel carriers 11 are connected with the toughened glass cover plate 2.

[0020] When the track wheels 7 move along the track 1, the toughened glass cover plate 2 is horizontally moved by the wheel carriers 11. When the toughened glass cover plate 2 is horizontally moved above the viewing window gap, the biological pool is in a closed state. When the toughened glass cover plate 2 is horizontally moved above the galvanized steel cover plate 3, the viewing window gap is opened, the anti-falling net 4 is exposed, and the running state of the equipment and facilities in the pool, including the liquid level and the aeration state, can be clearly seen through the anti-falling net 4.

[0021] ​In the specific production, the galvanized steel cover plate 3 is fixed firmly by angle iron frame; the anti-falling net 4 is in the form of stainless steel wire net and is fixed on the whole pool opening plane (between the galvanized steel cover plate 3 and the biological pool liquid surface).

[0022] In order to improve the automation degree of the device, a driving motor 6 is installed at one side of the tempered glass cover plate 2, and the power output shaft of the driving motor 6 is connected to the axle of the track wheel 7 through a shaft coupling. The driving motor 6 drives and follows the horizontal movement of the tempered glass cover plate 2.

[0023] Further, a limit block 10 is installed on the concrete foundation platform 8, and a contact limit switch cooperating with the limit block 10 is arranged on the tempered glass cover plate 2. When the tempered glass cover plate 2 runs to the fully open state of the observation window gap, the contact limit switch touches the limit block 10, the contact limit switch acts, and the driving motor 6 is automatically powered off.
