Description

[Detailed description of the invention] The present invention has a flange projecting obliquely or downwardly from the outer circumferential wall of the container 1 so that the tip edge of the flange 3 is positioned lower than the opening edge 2 of the container 1. opening 4
Bend the peripheral edge of the cover 5 that covers the cover 5 downward, and roll the lower end of the downwardly bent portion of the peripheral edge of the cover 5 inward to form a rolled-up part 11. The present invention relates to a container with a cover that is fixed to the edge with screws 7, and its purpose is to provide a container with a cover that can surely prevent rainwater from entering the container.

Conventionally, in a container with a cover, such as a solar collector, which covers the water inside the container with a cover to prevent rainwater from getting into the container, as shown in FIG. A flange 3 is provided protrudingly, the peripheral edge of the cover 5 is overlapped on the top surface of the flange 3, both are held down with a presser metal fitting 6, and the cover 5 is fixed with screws 7, but in this case, the cover 5 and There is a disadvantage that rainwater easily enters the container 1 through the gap between the horizontal flange 3 and the penetration hole of the screw 7 of the cover 5, and if the cover 5 is thin, the cover 5 can be easily torn by the penetration of the screw 7. There was also.

The present invention eliminates these conventional drawbacks.

The present invention will be explained in detail below based on the illustrated embodiments.

The container with a cover of the present invention is used as the solar collector A of a circulating solar water heating system as shown in Fig. 7, and the water stored inside is heated by solar heat.

This device functions to circulate hot water in a solar collector A with a pump B and store it in a hot water storage tank C.

The internal structure of the container 1 is such that a heat collecting panel 9 is provided on a heat insulating material 8 as shown in FIG.

At the opening edge 2 at the upper end of the outer circumferential wall of the container 1, a substantially inverted cover mounting flange 3 extends laterally and downwardly as shown in FIG.

The cover 5 is made of a transparent material, covers the opening 4 of the container 1, has a peripheral edge along the outside of the flange 3, and extends from the lower edge of the hanging portion 10 of the flange 3, which is located lower than the opening edge 2 of the container 1, to the flange 3. The screw 7 is inserted into the flange 3 and the rolled-up portion 11, and is fixed to the flange 3.

Since the cover 5 is layered in multiple layers in the winding part 11, tearing does not occur when the screws 7 are inserted, and the peripheral edge of the cover 5 can be securely fixed.

Here, to fix the cover 5, as shown in Fig. 3a, apply the oval-shaped presser metal fitting 6 to the hanging part 10 of the flange 3 so as to sandwich the cover 5, and then tighten the screws 7 from the presser metal fitting 6. By doing this, the cover 5 can be clamped and fixed between the surface of the presser metal fitting 6 and the surface of the hanging part 10 of the flange 3, and the cover 5 can be fixed.
Stress will not be concentrated only around the perforation hole of the screw 7, and this can be done reliably without tearing the cover 5. In addition, as shown in the same figure, the flange 3 can be used as a presser fitting 6.
If you use a piece that is bent in the same shape as the shape of , and apply the presser metal fitting 6 to the flange 3 from the outside of the cover 5 and fix it with the screws 7, the clamping surface of the cover 5 will be further expanded and the pressing can be carried out reliably. That will happen.

Furthermore, as shown in the figure, by forming the winding part 11 of the cover 5 using a pipe 12 and passing the screw 7 through this pipe 12, the winding part 11 can be securely fixed.

FIG. 4 shows an example of a change in the shape of the flange 3 extending from the opening edge 2 of the container 1. A winding part 11 is formed on the peripheral edge, a presser fitting 6 is placed over the winding part 11 and the flange 3, screws 7 are tightened, and a cover 5 is clamped.

FIG. 5 shows an example in which the flange 3 is provided in the middle part of the outer peripheral wall of the container 1. The flange 3 is extended diagonally downward and the cover 5 is attached to the upper part of the outer peripheral wall of the container 1 and the flange 3 using a presser fitting 6.
It is fixed by being pressed into contact with the

6a to 6a each show an example in which a flange 3 is provided in the middle of the outer peripheral wall of the container 1, and a spacer flange 19 is provided above the flange 3, and the flange 3 and the peripheral edge of the cover 5 are connected to each other. Even if rainwater should enter the container 1 through the close contact part, the space 20 formed between the flange 3 and the upper spacer flange 19 prevents the rainwater from entering due to capillary action and prevents rainwater from entering the container 1. This makes it possible to more reliably prevent contamination.

The present invention has a flange projecting obliquely or downwardly from the outer circumferential wall of the container so that the tip edge of the flange is positioned lower than the opening edge of the container, and the periphery of the cover that covers the opening of the container. The cover is folded downward, and the lower end of the downwardly bent portion of the periphery of the cover is rolled inward to form a rolled-up part, and this rolled-up part is fixed to the tip edge of the flange with screws. The fixing position of the peripheral flange is lower than the opening edge of the container.

Therefore, even if rainwater intrudes through the gap between the flange and the cover, this intruding rainwater will not reach the opening edge of the container, and it is possible to reliably prevent rainwater from entering the container.

In addition, the downwardly bent portion of the periphery of the cover prevents rainwater from entering the container, and the downwardly bent portion of the cover periphery is fixed to the tip edge of the flange located lower than the opening edge. Therefore, even if rainwater infiltrates through the fastened parts such as screws, it will not enter the container, and the tip edge (lower end) of the flange that extends diagonally or downwards will prevent rainwater from entering the container. If water is drained and water infiltrates into the container, there are cases where the wrapped part is fixed by wrapping around the tip edge of the flange, and cases where it is fixed by overlapping the tip edge of the flange (the first case). (Fig. 4), but when the rolled-up part wraps around the tip edge of the flange, the lower end of the flange is covered by the rolled-up part, so even if rainwater concentrates on the lower end of the flange, which is the drainage part. , rainwater is prevented from entering the container due to capillary action between the flange and the downwardly bent part of the cover, and when the rolled part is fixed so as to overlap the tip edge of the flange, the rainwater is rolled inward. The curvature creates a space between the flange and the downwardly bent part of the cover, which prevents rainwater from entering the container due to capillary action, and in any case This has the advantage of preventing rainwater from entering from the edge of the container due to capillary action.

In addition, since the periphery of the cover is rolled up and the rolled up part is fixed to the flange with screws, there is no risk of the cover being layered in the rolled up part and being torn by passing through the screws, ensuring that the cover is firmly fixed. It is something that you will be able to do.
