Description

[Detailed description of the invention] The present invention is based on a system in which a partition wall having a water outlet is tilted between a water inlet and a water outlet formed on both sides of the lower part of the water lock body, and the upper and lower operating rods are mounted approximately in the center of the water lock body. The purpose of this invention is to improve a synthetic resin water lock in which a valve provided at the lower part thereof with the same slope as the partition wall is detachably attached to the periphery of the water outlet and can be opened and closed. The purpose of this is to improve the adhesion of the valve to the periphery of the water outlet, thereby making it possible to accurately adjust the water level of irrigation water, groundwater, etc.

This type of synthetic resin sluice is used to adjust the water level of irrigation water, groundwater, etc., and since this water level adjustment is done by opening and closing a valve installed at the bottom of the sluice body, the valve naturally requires watertightness. Ru.

However, molded products made of synthetic resin suffer from distortion during molding, and the operating rod is a long rod of about 2 m that is easily bent, and the upper cap is located in the center of the lock body. Because of the regulations, it is extremely difficult to bring the valve provided at the bottom of the valve into contact with the periphery of the water outlet in a watertight manner.

This invention was devised in view of the above, and
The embodiment of the present invention shown in the drawings will be described below.
A partition wall 5 having a water discharge port 4 is tilted between the drain ports 3, and the lower part thereof is provided with the same slope as the partition wall 5 above by means of the upper and lower parts of the operating rod 6 attached to the approximate center of the water lock body 1. In the valve 7 which is detachably attached to the periphery of the water outlet 4 and can be opened and closed, when the operating rod 6 is cut off and the operating rod 6 is inserted, a predetermined gap is formed between the pipe walls. A synthetic resin made by fitting the cut portion of the operating rod 6 into a short tubular adapter 8 having a diameter of about 100 mL, and connecting the fitted operating rod 6 and adapter 8 with a stopper 9 so that they can swing relative to each other. It is a water lock.

The attachment point of the stopper 9 is preferably formed so that the upper and lower parts thereof are perpendicular to each other so that the valve 7 can swing back and forth and left and right, as shown in FIGS. 2 and 3.

As is clear from the above, in the present invention, the operating rod 6 is interposed with the adapter 8 that can swing with respect to each other, so that the mounting position of the operating rod 6 may be misaligned, or the operating rod 6 itself may be bent. Although the above distortion occurs, the third
As shown in the figure, the position is corrected by swinging the operating rod 6 and adapter 8 of the valve 7 part, and the valve 7 is evenly attached to the periphery of the water outlet 4 to achieve the desired water tightness. It is something that can be effective.

Claims (1)

[Scope of utility model registration request] A partition wall with a water outlet is tilted between the water inlet and drain port formed on both sides of the lower part of the water lock body, and the same slope as the partition wall is made at the bottom by the upper and lower operation rods attached to the approximate center of the water lock body. In a device in which an attached valve is removably attached to the periphery of the water outlet and can be opened and closed, when the operating rod is cut and divided into two vertically, and the cut portion of the operating rod is inserted. The cut portions of the operating rod are fitted into both ends of a short tubular adapter having a diameter large enough to form a predetermined gap between the tube walls, and the fitted operating rod and adapter swing back and forth and left and right relative to each other. A synthetic resin water lock whose mounting points are connected by fasteners that are perpendicular to each other so as to achieve the desired results.
