Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a synthetic resin sluice used for adjusting the water level of irrigation water, groundwater, etc.

[Conventional technology]

Conventionally, synthetic resin water locks have a cylindrical water lock body with a valve formed at its lower end between the water inlet and drain port, the upper end of which protrudes above the water lock body, between the upper and lower ends of the valve body. Those designed to force people to move are generally used.

[Problem that the invention attempts to solve]

However, this type of synthetic resin water lock is the third
As shown in the figure, because the top of the water lock body is buried at the end of the ridge so that it protrudes above the ground surface, damage accidents frequently occur due to contact with working machines or children's mischief. However, it had the disadvantage that the intended function could not be maintained.

[Means to solve the problem]

This device was devised to solve the above-mentioned drawbacks of the conventional products, and consists of an operating tube whose upper end protrudes above the water lock body between the water inlet and drain port provided on both sides of the lower part of the cylindrical water lock body. A synthetic resin water lock, in which a valve formed at the lower end can be attached and removed by the upper and lower sides of the lock, is shielded with a curing pipe fitted with a cover plate, and this cylindrical curing pipe is attached to the upper outer peripheral surface of the water lock main body. The problem was solved by making it fit tightly.

〔Example〕

The embodiment of this invention shown in the drawings will be explained in detail below. Fig. 1 is a partially cutaway front view showing an embodiment of the synthetic resin water lock of this invention.
is a cylindrical water lock main body, 2 and 3 are a water inlet and a drain port provided on both sides of the lower part of the water lock main body 1, and 4 is removably fitted between the water inlet 2 and the drain port 3. Reference numeral 5 denotes an operating pipe installed above the valve 4, and the upper end is located above the water lock main body 1 so that the valve 4 can be operated from the ground. A curing pipe 6 is attached to the upper outer peripheral surface of the lock main body 1 so that at least the surface protruding portion of the water lock main body 1 and the upper end of the operating pipe 5 are shielded. A pipe having a thicker wall than the water lock main body 1 is used, and 7 indicates a cover plate attached to the upper opening of the curing pipe 6.

[Effect of idea]

As is clear from the above, in the synthetic resin water lock of this invention, the cylindrical curing pipe 6 is attached so as to be in close contact with the upper outer circumferential surface of the water lock main body 1, so that the ground surface of the water lock main body 1 and the operating pipe 5 is As shown in Fig. 2, the protruding portion is completely shielded by the curing tube 6 and the cover plate 7, which significantly reduces the damage accidents seen with conventional products.
Since the curing tube 6 is in close contact with the ridge, there is no movement of the curing tube 6 when creating a ridge during plowing, which improves transportability and workability.Furthermore, since the cover plate 7 is attached, the curing tube 6 does not move when creating a ridge. It also has features such as preventing water from accumulating and also preventing children from playing pranks by attaching a key to the cover plate.
