Abstract

(57) [Summary] [Purpose] In a floodgate used outdoors to stop and drain water in a river or irrigation channel, a floodgate opening / closing switch that uses operating rods such as a spindle or a rack is used as bird droppings. The present invention relates to a structure for preventing dirt. [Structure] 1) Preventing the retention of birds, which is a cone or a cone-like body (such as a spire) having a steep slope with a sharp apex angle of about 30 ° to 60 ° on the top of the tubular body of the protective cover during operation. A gate opening / closing switch having a part. 2) A bird's retention preventing part is provided by making the obstruction plate at the top of the tubular body of the protective cover at the time of operation an angle of about 30 to 60 ° with respect to the central line of the tubular body and forming a steep slope with a sharp tip. The switch for the floodgate, which is characterized by

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This device is installed outdoors to prevent the gates of floodgates that use operating rods such as spindles and racks from being polluted by bird droppings in the floodgates that are used to stop and flow water in rivers and waterways. It is for.

[0002]

[Prior art]

 For switches that use rod-shaped members (operating rods) such as spindles and racks to lift and push down the doors of sluices, in order to protect the operating rods and the switch body from wind and rain and dust, It is common to provide a cover using a steel pipe with a circular or rectangular cross section on the upper part of the main body so as to stand upright.

However, since this protective cover projects from the ground to an appropriate height and has a flat part by a closing plate at the top, birds often stay and rest, and the feces emitted at this time are opened and closed by a switchgear. And the area around it were polluted, which caused management problems such as giving off a foul odor and soiling the clothes of the manager.

[0004]

[Problems to be solved by the device]

 Therefore, various attempts have recently been made to prevent birds from staying on top of the protective cover of the operating rod.

That is, (1) A small number of fine steel bars are pierced in a needle shape on the closing plate at the top of the protective cover. (2) About four steel plates with sharpened tops are attached to the blocking plate on the top of the protective cover. (3) Instead of using a single pipe for the protective cover, several sheath pipes were used, and the height of the top of the protective cover was lowered to prevent birds from staying when the door fell.

Although these attempts have some effect, the methods of (1) and (2) are effective for large birds, but small birds may remain without difficulty and may be incomplete. Not only that, but it can be installed at a small cost, but it is bad for the appearance and it harms the harmony of the entire floodgate equipment, so it is good for civil engineering structures that emphasized familiarity to people living in the neighborhood. It was a weak point in forming a beautiful landscape.

Further, the method (3) is a method that is generally not effective unless it is a floodgate, such as a sand removal gate, in which the door body is lowered to the maximum limit. After all, if it is higher than the vicinity, the bird stays and feces.

Based on such experience, it is intended to prevent the retention of birds by making the entire top part of the protective cover of the operating rod a steep slope, and in addition, various changes were made in forming the steep slope. By adopting a shape, it is intended to introduce a new flexible impression to the sluice gate opening / closing switch, which had a traditional impression of being a skeleton.

[0009]

[Means for Solving the Problems]

 That is, the sluice gate opening and closing device of the present invention is a cone or a cone-like body having a steep slope with a sharp apex angle of about 30 ° to 60 ° on the top of the tube body of the protective cover of the operating rod (a spire shape or the like). It is characterized by having a bird retention preventing part consisting of

Further, in the water gate opening and closing device of the present invention, the closing plate at the top of the pipe body of the protective cover of the operating rod has an angle of about 30 ° to 60 ° with respect to the center line of the pipe body, and the tip is sharp. It also features a steep slope that serves as a bird retention area.

[0011]

[Action]

 In this way, the bird's retention prevention part by forming a steep slope on the top of the tube of the protective cover of the operating rod is accompanied by a slight increase in the processing cost, but the closed part of the tube is a steep slope and the tip is The sharpness completely prevents birds from staying.

Furthermore, since the steep slope required by the bird retention prevention unit can be selected in a variety of shapes such as a cone, a cone approximation, a flat surface, and a curved surface, it is possible to decorate the sluice gate switch with It has the effect of softening the bones and creating a familiar appearance.

【Example】

 An embodiment of a water gate opening / closing device of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view of a sluice including a spindle type flat wound type manual switch having a bird retention preventing portion 5 on the top of a spindle cover 4c.

The door body 2, which guides and moves up and down by the door stop 1 to flow and hold water, is operated by a manual switch 4 via a spindle 3 connected to the upper part.

Now, when the operator turns the handle 4a of the manual switch 4, the screw 4b rotates to connect to the handle 4a, so that the spindle 3 moves upward or downward by the screw. Since this is the movement of the door body 2 at the same time, the purpose of the operator is achieved.

Also in this case, the manual opening / closing operation is performed in order to prevent the performance of the manual opening / closing apparatus 4 from being deteriorated due to the fact that the screw surface of the spindle 3 or the rotating portion of the manual opening / closing apparatus 4 is exposed to wind and rain or dust is attached. At the top of the machine 4, a spindle cover 4c stands up with a length that allows for a slight margin in the amount of vertical movement of the spindle 3.

Since the top portion of the spindle cover 4c has the bird retention preventing portion 5 formed by the pointed conical body having the apex angle of 45 °, the bird cannot stay on the top portion of the spindle cover 4c. Therefore, there is no damage from bird droppings.

FIG. 2 shows a bird retention preventing portion having a shape similar to a cone resembling the steeple of a temple in the Middle East, which is provided on the top of the operation rod cover having a tubular body with a circular cross section.

In FIG. 3, the obstruction plate provided on the top of the operation rod cover with a tubular body having a rectangular cross section is a steep surface having an angle of about 30 ° with the center line of the tubular body, and the highest part of the obstruction plate is the top portion of the tubular body. The bird retention | prevention prevention part made into the shape which the tip was made to correspond to one corner is shown.

[0021]

[Effect of device]

 The sluice gate opening and closing device having a bird retention prevention portion of the present invention involves a slight increase in processing cost due to the formation of the steep slope on the top of the pipe body of the operation rod protective cover as described above. All of the occlusions are steep slopes and the tip is sharp enough to prevent bird retention.

Furthermore, since the steep slope required by the bird retention prevention unit can be selected in a variety of shapes such as a cone, a cone approximation, a plane, and a curved surface, it is possible to decorate the sluice gate switch with It has the effect of softening the bones and creating a familiar appearance.
