Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a drain mechanism for a fire hydrant, and particularly to one that prevents clogging near the tip of a drain pipe.

[Prior art and problems]

In general, a fire hydrant is used to drain residual water inside the hydrant to the outside through a drain pipe, and gravel is laid near the tip of the drain pipe so that water can be drained without any hindrance.

However, after a certain period of time, the earth and sand existing around the area where the gravel is laid (particularly on the sides and top) loosens due to the passage of drainage and enters the gravel, blocking the gaps between each gravel and causing clogging. There is.

As a result, residual water in the fire hydrant cannot be drained,
In winter, the residual water freezes, causing accidents such as damage to fire hydrants, and problems such as the need to dig up the area near the tip of the drain pipe to repair it.

[Purpose of invention]

The present invention was developed in view of the above-mentioned problems, and it is an object of the present invention to provide a drain mechanism for a fire hydrant, which has a partition container body made of a wall for preventing the inflow of earth and sand around a place where gravel is laid.

[Structure of the idea]

The present invention combines earth and sand inflow prevention walls to form a partitioned container main body, a drain pipe insertion port and a drainage opening are formed in a part of the partitioned container main body, and a fire hydrant drain pipe is inserted into the drain pipe insertion port. The drain mechanism of a fire hydrant is characterized in that the partition container main body is filled with a void material such as gravel.

[Example of idea]

Next, the present invention will be explained with reference to the embodiments shown in the drawings.

Figure 1 is a longitudinal sectional front view of the present invention, Figures 2 and 3
The figure is a longitudinal sectional front view of the main body of the partitioned container.

1 is a fire hydrant, 2 is a main valve for guiding water from the main pipe into the fire hydrant 1, 3 is a drain valve for draining residual water in the fire hydrant to a drain mechanism, and 4 is a drain pipe.

Further, reference numeral A denotes a main body of the partitioned container installed near the tip of the drain pipe, and 5 is a wall for preventing the inflow of earth and sand, which constitutes the main body of the partitioned container, and is usually made of metal such as stainless steel or synthetic resin. A drain pipe insertion port 6 and a drainage opening 7 are formed at appropriate locations, and the inside of the partitioned container main body A is filled with a void member 8 such as gravel.

The drainage opening 7 of the partitioned container main body A may be provided at any position, but as an example, as shown in FIG. 2, the drainage opening 7 can be formed at the lower part of the partitioned container main body A to improve drainage. .

Furthermore, the shape of the partitioned container main body may be any shape, but if the shape is in the shape of an upside-down square, the effect of preventing the inflow of earth and sand will be perfect, and the upper part of the partitioned container main body A can be freely removed as shown in Fig. 3. You may make it form in the lid body 9 which becomes. Further, in order to further strengthen the connection between the partition container main body A and the fire hydrant 1, it is also possible to provide a fixing stainless steel band between the two.

As mentioned above, in the present invention, the tip of the drain pipe 4 is inserted into the drain pipe insertion port 6 of the main body A of the partitioned container, and the void member 8 such as gravel is filled in the main body A of the partitioned container. It becomes possible for residual water in the fire hydrant 1 led into the interior of the fire hydrant 8 to escape into the soil through the drainage opening 7.

At this time, since each wall surface of the partition container main body A is formed with a sediment inflow prevention wall 5, the water is drained through the drainage opening 7.
There is no escape to the outside from other places, and therefore, finer earth and sand from the outside of the partition container body is completely prevented from flowing into the vicinity of the gap between the cavity members.

In particular, when the upper part of the partitioned container main body A is formed into a removable lid 9, it is possible to easily fill the gap member into the partitioned container main body after connecting the partitioned container main body to the drain pipe. There is a practical benefit of shortening the overall construction time.

[Effect of idea]

Therefore, with this invention, the remaining water in the fire hydrant can be completely drained from the drain pipe at all times, and of course, accidents such as clogging with earth and sand near the drain mechanism do not occur, which naturally reduces the need for repair work. This has practical effects, such as eliminating the need for digging work.
