Abstract

PROBLEM TO BE SOLVED: To smoothly open and close a sluice gate by a play produced due to movement by a method wherein a moving lever having a mounting part engraved in a tip is formed on the outer peripheral side of the moving main body of a moving regulating body. SOLUTION: A sluice gate 1 is provided with a reinforcing mounting plate 2 having a side wall 8 corresponding to the vertical direction of the central part of one front of a surface and a back and performing a role of reinforcement and a role for mounting a moving regulating body 3, and a moving regulating body 3 is rotatably mounted in the vicinity of the upper end of the reinforcement mounting plate 2. A moving main body 9 in the central internal part of which an internal screw 10 is formed is arranged at the moving regulating body 3, and a moving lever 11 is protruded laterally horizontally of the outer peripheral side. When a so formed mobile opening closing device for the sluice gate is used, a ladder type screw 5 is rotated through rotation of an operation handle 15, and a reinforcement mounting plate 2 and the sluice gate 1 are integrally raised through engagement of an internal screw 10 of the moving main body 9 of the moving regulating body 3. In this case, even when an operation handle 15 is rotated in an inclination state, the moving regulating body 3 is moved to produce a play, whereby smooth and easy elevation and opening and closing are practicable.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening / closing door of a water gate used for agriculture such as paddy fields, irrigation channels, fish farms or for fisheries.
Its main purpose is to provide a movable opening / closing device for a water gate for preventing agility of operation and damage by making the water gate open / close.

[0002]

2. Description of the Related Art In a conventional device for opening and closing a water gate such as a water channel using a handle of this kind, as shown in FIGS. 7 and 8, a door frame (23) provided on a body (22) of the water channel. The sluice door (18) is provided for the sluice gate (18) that is opened and closed by raising and lowering the inside of the sluice. (1
It is known that the one for opening and closing 8) is generally used.

[0003]

SUMMARY OF THE INVENTION In the above-mentioned conventional sluice door opening / closing device, it is very difficult to open / close the sluice door due to the water pressure from the water channel at all times, and the raising / lowering of the sluice door. When opening and closing, the operating handle is right above the sluice gate,
A supporting frame that acts as a guide rail by tilting the sluice door when moving up and down because rotation force from the front and rear or left and right directions acts during operation and does not play in rotation with the screw bearing fixed to the ladder screw for lifting. There was a problem that it bite into and the lift opening and closing did not work smoothly. The present invention has been made in view of such problems as described above, and during the opening / closing operation of the sluice door, the movable adjustment body is smoothly started even when the rotational force related to the operating handle is changed. For the purpose of providing a movable opening / closing device for a sluice door that can smoothly move the sluice gate up and down when operating a trapezoidal screw and solve immobility such as the sluice door being locked by a support frame. There is.

[0004]

In order to achieve the above object, the sluice gate of the present invention is supported by a rectangular frame-shaped support frame so as to be able to move up and down. Attach the reinforcing mounting plate with the side wall. A movable adjusting body is pivotally mounted near the upper end of the reinforcing mounting plate. The movable adjusting body is provided with a movable main body having an inner screw engraved in the center thereof, and a movable rod having an attachment portion at the tip is formed on the outer peripheral side surface of the movable main body. The lower end of the trapezoidal screw supported on the upper portion of the support frame is rotatably screwed to the movable adjusting body at the attachment portion of the movable main body. Further, the tip of the movable rod is movably mounted on the side wall with a nut portion.

[0005]

The operation of the movable opening / closing device for the water gate constructed as above will be described. When water is taken into a paddy field, the trapezoidal screw (5) is also rotated by the rotation of the operating handle (15).
The reinforcing attachment plate (2) and the sluice door (1) are integrally lifted by the engagement of the inner screw (10) of the movable main body (9) of the movable adjusting body (3). At this time, even if the operation handle (15) is not horizontally rotated but is rotated, for example, in a front-back or laterally tilted state, the movable adjustment body (3) is moved and play is generated, so that the water gate ( In 1), it is possible to open and close easily without difficulty, and to open and close easily even under high water pressure.

[0006]

EXAMPLE Next, an example of the present invention will be described with reference to the drawings. In a floodgate door (1) made of stainless steel or the like installed as water intake in a waterway such as a paddy field, an irrigation canal, a fish farm, etc., FIGS. As shown in FIG. 3, the sluice door (1) is fitted in a support frame (7) having a rectangular frame shape and a long channel shape so as to be vertically movable. Further, the sluice door (1) is provided with a side wall (8) facing the longitudinal direction at the center of the front surface on either the front or back side. The reinforcing mounting plate serves as a reinforcing member and a mounting member for the movable adjusting member (3). 2) is attached. The movable adjusting body (3) is rotatably mounted near the upper end of the reinforcing mounting plate (2). As shown in FIG. 6, a movable main body (9) having an inner screw (10) engraved in the center thereof is positioned on the movable adjusting body (3), and the movable main body (9) has left and right outer peripheral side surfaces. Horizontally movable rod (1
The movable rods (11) and (11) are provided with protrusions (1) and (11), respectively, and mounting portions (12) and (12) are formed on the tip of the movable rods (11) and (11). The side wall (8) is attached to the attachment portion (12) (12).
The attachment parts (12) (12) penetrating the (8) are fixed from the outside with attachments such as nut parts (13). Reference numeral (15) designates a bearing bearing (16) at the upper end of the trapezoidal screw (5) for moving up and down the sluice gate (1).
(6) is a mounting frame that supports a support frame (7) that guides a sluice door (1) mounted on a skeleton (17) such as concrete.

[0007]

EFFECTS OF THE INVENTION Since the present invention is configured as described above, the lifting force and the like related to the support frame and the sluice door are inclined so that the sluice door is fixed to the conventional trapezoidal screw and lifted and lowered. It has an excellent effect that it can be operated lightly without any anxiety such as change, and that the water gate opening / closing device can be operated smoothly without difficulty. The sluice door is supported by a rectangular frame-shaped guide rail and can be stably constructed, and it has the effect of reinforcing the sluice door with a reinforcing mounting plate provided with a vertical side wall in the center of the sluice gate. is there. Further, the movable adjusting body mounted on the upper end of the reinforcing mounting plate has an effect that it can be smoothly operated while moving the screw even when the trapezoidal screw is forced to rotate. Further, since the movable adjusting body is integrally formed with the movable main body having the inner screw at the center and the horizontal movable rod on the outer peripheral side surface of the movable main body, the trapezoidal screw can be screwed onto the movable main body without difficulty. At the same time, the movable rod has an effect that the attachment tool can be rotatably and firmly attached to the side wall of the reinforcing attachment plate in a similar manner.
