Description

[Detailed Description of the Invention] The present invention relates to an odor-proof lid that is useful for environmental conservation and labor saving in sewage treatment plants and the like.

As this type of conventional deodorizing cover, a pontoon type cover consisting of a plurality of sheets is often used. However, this type of lid is not useful as a complete odor-proof cover, and when carrying out work such as scraping up sediment that has accumulated at the bottom of the settling basin, the lid must be removed manually. There was also the inconvenience of having to move or move. In other words, in order to carry out this work, a large amount of manpower and a large amount of time are required, and since these works are currently being carried out through outsourcing, it requires a large amount of expense. It was.

In view of these circumstances, the applicant has already
They have devised a device that is made up of multiple panels and can be folded upright with hinges between the panels, and have filed an application for utility model registration.This device is used to achieve the same purpose, but it Instead of the upright movement/storage system proposed in 2011, the aim is to provide a horizontal movement system.

That is, the purpose of the present invention is to eliminate the various drawbacks of this type of odor-proof lids that have been known in the past, and to eliminate the wasted human labor and time required for operations that were required in the prior art. To provide an odor-proof lid for a settling basin for a sewage treatment plant, etc., which can completely prevent odor and can be opened and closed automatically.

In order to achieve this objective, the present invention has been developed so that the side walls facing each other are placed on the peripheral edge material of the side wall of the settling basin, which is installed above the liquid level of the settling basin, so as to cover the entire surface of the settling basin. Consists of a plurality of panels placed close together on the sides, with support for the panels being provided by the edges, and each adjacent panel having mutually perpendicular panels at opposite ends. The panels are releasably connected by directional intermeshing couplings, and the panels are connected over a receptacle at one end of the side wall of the settling basin and on a panel at the opposite end of the recess. By rotating the sprocket wheel with the electric speed reducer, both ends of the sprocket wheel are engaged with chains fixed on each side wall at the end of the settling basin, so that each panel is moved from the panel on the storage platform side. The present invention is characterized in that the panels are sequentially moved to a storage stand, and each panel is stored one by one in a vertically overlapping manner using a lifting device provided on the storage stand.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to FIGS. 1 to 8 of the accompanying drawings showing embodiments thereof.

The figure depicts the present invention implemented as an odor-proof lid for a settling basin in a sewage treatment facility, but the outline of such a treatment facility is that sewage and rainwater from homes, factories, etc. The sediment is collected in the sewer pipe and enters the pumping station of the sewage treatment plant, but before that, it first passes through a gate and enters the settling basin, and as it flows slowly into the basin, the sediment is collected in the pond. sink to the bottom. This settled earth and sand is removed by a bucket, and large garbage is
removed by screen and scraper,
The method is then used to suck it up with a pump, discharge it, and direct it to a sedimentation pond at a sewage treatment plant.
In such sewage treatment facilities, the upper part of the settling basin is covered to prevent the strong odor generated from the liquid level of the settling basin from deteriorating the surrounding environment. This embodiment is intended for such a deodorizing lid.

Although the present invention has the above configuration,
Next, its operation will be explained.

(1) Release operation 1 If necessary, release the installed lashing device.

2 Operate the motorized sprocket 56 built into the drive panel ₁₁ to move the side wall 50 of the sand settling basin 50.
₁ and 50 ₂ , each panel 1 ₁ to 1 ₄ is caused to travel via the guide members 53 ₁ and 53 ₂ and each wheel 2 ₁ to 2 ₄ and stored. It is moved in the direction of the stand 52.

3 Attach the panel ₁ closest to the storage base 52 to a stopper member (not shown) provided on the storage base 52.
Sprocket 56 of drive panel ₁₁ when a stopper (not shown) attached to the
Stop the operation and stop the movement of panels 1 _{to 4} .

4 In this way, the first panel 1 ₄ is positioned at the bottom of the lifting frame 57 of the storage device 54 .

5 By operating the drive device 66 of the lifting device 52, the lifting frame 57 is lowered via the wire 63, and a link-shaped lifting hook is attached to the lower part of the lifting arm ₁₄₀ attached to the panel ₁₄ . Hook 7 at the top of 70, 71, 72
The panel ₁₄ is lifted up via the lifting frame ₅₇ by the operation of the drive device 66. In this case, in order for the engagement protrusion ₇₀₀ of the lifting hook member 70 to fit into the lower part of the lifting arm ₁₄₀ , it must be attached to the end of the lifting arm 140 by pivoting with the pin ₇₃ of the hook member 70. , by entering along the lower slope of the engagement protrusion ₇₀₀ .

6 When the next panel 1 ₃ is positioned by the same stopper as the panel _{1 4 by} driving the drive panel 1 1 , the lifting frame 57 from which the panel 1 ₄ is suspended is lowered by the operation of the drive device 66 . , hook this panel ₁₃ onto the next hook member 71 and lift it up.

7 Repeat this step by step.

8. Finally, the drive panel 1 ₁ is placed under the storage stand 52, and at this point the upper surface is completely opened to the sand settling basin 50.

(2) Closing operation Basically, this is done by reversing the opening operation. The panel moving in the closing direction and the panel lowered from the retracted state are connected by a joint 80, and this operation is repeated one after another until the drive panel 1 ₁
This is accomplished by the engagement of the sprocket 56 and the chain 50.

Since the device of the present invention has the above-described configuration and operation, it is clear that it can exhibit the following effects.

() It is possible to eliminate wasted human labor and time consumption, which were technical problems with conventional odor-proof lids of this type. () Odors can be completely prevented by attaching a gasket to the periphery of the panel. () ) Panels can be opened and closed automatically, contributing to labor savings.

Although the present invention has been described above as being implemented as an odor-proofing lid for a sand settling basin in a sewage treatment facility, the present invention is not limited to such use, and can be used widely for odor-proofing and wind and rain protection. Needless to say, it can be used as a lid that requires a high density.
