Description

DETAILED DESCRIPTION OF THE INVENTION This invention is designed for use in cold regions. In particular, it relates to a water dispenser box for general household use.

A water meter box accommodates a water meter and a water stop valve together with a part of its piping, and is buried underground with the top lid flush with the ground surface. As shown in the cross-sectional view, there are multiple stages (two stages ρ in Figure 1) depending on the depth of the place where the rectangular frame-like body 1 made of hard synthetic resin or the like is buried.
An example was given. ) They are stacked to form a peripheral wall, and a bottom plate 2, a lid plate 5, and an inner lid 4 are arranged on this to form a single box body.

Generally, in cold regions, to protect water meters from the cold air, they are buried underground at a depth necessary to accommodate the cold weather in the region and kept at a relatively constant temperature.

For example, in the Noh region of Hokkaido, the rectangular frame bodies are buried at a depth of about 50 cm and in the Kitami region, about 150 degrees deep. In this case, in cold regions, the vicinity of the stratum surface freezes and swells during the winter, and the retention area between the rectangular frame at the depth at which the swell occurs, the so-called frost heaving depth, and the rectangular frame directly below it. There is a danger that the water meter may become frozen if it comes off, and the rectangular frame-shaped body buried underground is often destroyed by heavy pressure from above or earth pressure, which is especially noticeable in areas with heavy traffic. For this reason, the above-mentioned rectangular frame is made of cast iron for the lid, and the area near the ground surface of the rectangular frame is also reinforced with cast iron, etc., but it is still not sufficient and the reinforcement is periodically (every 8 years)
The water meter box had to be repaired and replaced even at times other than when the water meter was replaced.

This invention particularly relates to a water dispenser box for general household use.
It is designed to efficiently maintain a constant temperature of the water meter and water stop valve without the water meter box being buried deep underground or being destroyed or dislodged. The bottom part, which houses the container and water stop valve, should be of a specified size that does not interfere with plumbing work, etc.

The part extending from the top to the top cover is an integral cylindrical body, and its size is set to the minimum size that does not cause any problem in reading the meter of the water meter or operating the stop valve.

In other words, even in cold regions, the temperature underground is relatively warm, and the temperature near the surface of the ground changes depending on the temperature change.It is stored in the container and maintains heat retention by suppressing the inflow of cold air from above as much as possible. For this reason, in the present invention, a large amount of heat-retaining air is stored in the bottom part, which is a storage part, and the cross-sectional area of the cylindrical part, which becomes a passage for cooling air, is made small. It is made narrower to reduce the surface area that is cooled from the outside, and is pressurized so that the upper surface of the stored air is not completely cooled.

Embodiments of the present invention will be explained based on FIG. 2 (perspective view) and FIG. This is the part where the pipe 7, water meter 8 and water stop valve 9 are housed and installed.In this embodiment, the size of the base box part is approximately 42cx (length)
27 cm (width) x 25 CIE (height).

A water pipe for general household use with a diameter of 13 to 20 square meters was assumed. The base box part 5 has a rectangular frame-shaped threshold 11 on the bottom plate ioh surface.
The top plate 12 is fitted to the upper edge of the top plate 11 to form a single shallow box, and as mentioned above, it does not interfere with the piping of the water meter or water stop valve. It has enough space without any problems. This base box part 5 is normally made of reinforced plastic, but since it is buried deep underground, it may be made of normal hard synthetic resin in terms of strength.

Next, reference numeral 15 denotes a cylindrical body part, the lower end of which is fitted into a short cylindrical mounting part 14 of a required height provided near the center of the top plate 12 of the base box part 5, and stands upright vertically.

As described above, this cylindrical body part 16 has a cross-sectional size that is large enough to read the meter of a water meter and open and close a water stop valve.
300cIIL” (in the case of a circle, the diameter is approximately 20c)
lL) degree is sufficient. This cylindrical body portion 13 is made of a single piece of reinforced plastic, and may have any shape, such as a rectangular tube or a cylinder, but a cylindrical shape is superior in terms of strength against tonosho and the like.

Note that the short cylindrical mounting portion 14 may be provided with a lip 15 for reinforcing a portion or the entire portion thereof.

A lid 16 is fitted onto the L surface of the cylindrical body portion 16 . It is preferable that the upper surface of this lid body is formed into an arcuate convex surface in order to increase the strength and to better seal the lid body with the cylindrical body portion. If the lid is flat or concave, when a large load is applied to it, the lid will bend, creating a gap between the lid and the cylindrical body, or causing damage to the cylindrical body. If you fall inside, it will also become a tome.

As for the material of the lid, there is no need to use cast iron or the like as in the past, and a light-resistant reinforced plastic or the like is sufficient, and there is no need to particularly reinforce the vicinity of the ground surface of the cylindrical body.

The water dispensing box of the present invention has a heat retention effect because the convection of cold air is considerably prevented without using an inner lid as in the conventional case. It will be more effective if the inner lid 17 for heat insulation is placed in a locked state.

5(at) and (b) are a perspective view and a side sectional view of another preferred embodiment of the present invention. A cylindrical body portion 15 is fitted outside the short cylindrical attachment portion 14.

Therefore, it is different from the examples shown in FIGS. 2a and 2b in that there is no lip and that the inner lid 17 is mounted on the short cylindrical attachment part 13. This is preferable because there is no risk of dirt or the like entering between the two and the structure is simpler and easier to manufacture.

With the above configuration, the present invention has the base box portion 5 as described above.
The inside is always kept warm, and since it is a one-piece cylindrical body, even if frost heaves on the ground, the water meter box will maintain its installed position and will not freeze up. If the cylindrical part is shaped more than the base box part, it can withstand direct and indirect pressure such as the heavy pressure from above from cars and other heavy objects, and the lateral pressure from the ground, and can be used semi-permanently. It has many advantages such as ease of manufacture.
