JPS5923789Y2 - Synthetic resin water lock - Google Patents

Description

[Detailed description of the invention] The present invention relates to the improvement of a synthetic resin sluice used for removing groundwater in wetland areas and controlling irrigation water in agricultural areas, and its purpose is to The objective is to adapt to changes in the buried depth of underground drainage pipes.

This type of synthetic resin water lock is made of a pipe body with a predetermined length, so it is suitable for use when the underground water level is shallow and the underdrain drain pipe is buried in a relatively shallow place. The upper part of the synthetic resin water lock protrudes high above the ground, causing problems such as impeding traffic and agricultural work.

The present invention has been devised in view of the above, and an embodiment of the present invention shown in the drawings will be described below. 1 is a cylindrical water lock main body, an upper water lock main body 11 and a lower water lock main body 12. 2 and 3 are cylindrical water inlets and drains provided on both sides of the lower part of the water lock body 1, and 4 is a cylindrical water inlet and a drain which are inclined between the water inlet 2 and the drain 3. 5 is a water outlet drilled in the center of the partition wall 4, and 6 is a valve used to open and close the water outlet 5. Reference numeral 7 denotes an operating rod provided above the valve 6, which is located approximately in the center of the water lock body 1 and has a length such that the other end protrudes above the water lock body 1. Yes, 8
9 is a cap fixed to the upper end of the upper water lock main body 11, and 9 is a tubular projection formed approximately in the center of the cap 8, which is used for inserting and fixing the operating rod 7. , 10 is a sleeve formed at the lower end of the upper water lock main body 11, and is used for fitting into the lower water lock main body 12 made of a straight pipe.

As is clear from the above, the present invention has a water inlet 2 and a drain outlet 3 provided on both sides of the lower end of the cylindrical water lock body 1.
A partition wall 4 with a water outlet 5 provided therebetween is tilted, and a valve 6 provided at the lower part is fitted around the periphery of the water outlet 5 by upper and lower operating rods 7, so that the water lock body 1 is connected to the upper water lock body 11 and a lower water lock main body 12, and an operating rod 7 is inserted into the upper end of the upper water lock main body 11 approximately in the center and a tubular projection 9 is to be fixed thereto.
A sleeve 10 is formed at the lower end to fit into a lower water lock main body 12 made of a straight pipe, and an upper water lock main body 11 is removably fitted into the lower water lock main body 12. Therefore, when the length of the water lock main body 1 needs to be adjusted, such as when the underdrain drainage pipe is buried in a relatively shallow place, the lower water lock main body 12 should be adjusted so that the water lock main body 1 has the desired length. The upper part is cut to a predetermined length and the sleeve 10 is used to fit the upper water lock main body 11 into the lower water lock main body 12.

Therefore, with this invention, the length of the water lock body can be easily adjusted according to the buried depth of the culvert drainage pipe, thereby eliminating the conventional problems such as obstruction to traffic and agricultural work. be.

Claims (1)

[Scope of utility model registration request] A bulkhead with a water outlet between the water inlet and drain port provided on both sides of the lower part of the cylindrical water lock body is tilted, and the valve provided at the bottom is fitted around the periphery of the water outlet by moving the operating rod up and down. In the type of lock, the lock body is divided into an upper lock body and a lower lock body whose upper end is a straight pipe, and a tubular protrusion through which the operating rod is inserted is provided protruding from the upper end of the upper lock body. A synthetic resin that fixes the cap and forms a snub at the lower end of the upper water lock body to be fitted to the upper end of the lower water lock body so that the upper water lock body and the lower water lock body can be removably fitted. Water lock.
