DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pump gate in which a pump for forcibly discharging water from an upstream waterway of a gate to a downstream waterway is integrally attached to the gate, and more particularly to a dust removal apparatus installed in the upstream waterway. By attaching the machine to the gate and providing a trash receptacle on the upper end of the gate,
The present invention relates to a pump gate with a dust remover, which is capable of simultaneously moving a dust remover up and down only by raising and lowering the gate.

[0002]

2. Description of the Related Art Heretofore, there has been known a pump gate in which a pump for forcibly discharging water in an upstream channel of a gate to a downstream channel is integrally attached to the gate. A dust remover is attached to the upstream waterway of the pump gate in order to prevent floating dust from being sucked into the pump and causing the pump to fail. In the case of the pump gate, the gate is raised and opened at the time of natural drainage, and at the same time, the dust remover attached to the water channel on the upstream side of the pump gate is also raised so as not to hinder the natural drainage. . Also,
The pump gate has a structure in which the gate is closed at the time of forced drainage, and the pump is driven in a state where the dust remover is also lowered to forcibly drain the water in the upstream channel of the gate to the downstream channel through the drain pipe of the gate.

[0003]

However, in the conventional pump gate, since the dust collector to which the upstream water passage is attached and the pump gate are separate bodies, when the pump gate is moved up and down, dust is removed in accordance with this. It was necessary to raise and lower the machine separately, and for this reason, the dust remover had to be provided with a separate lifting mechanism. Furthermore, in the case where the elevating mechanism of the dust remover is installed on the upper part of the gate column holding the elevating gate, it was necessary to raise the rake in advance before ascending the gate.

The present invention has been made in view of the above problems, and has been made in order to solve the problems. An object of the present invention is to integrate a dust remover installed in an upstream waterway with a gate. By mounting the dust receiver on the upper end surface of the gate, the dust collector can be raised and lowered at the same time only by raising and lowering the gate, and there is no need to separately raise and lower the dust remover in accordance with the gate. It is an object of the present invention to provide a pump gate with a dust remover, which eliminates the need for a mechanism for raising and lowering the garbage and collects the scraped-up dust to the side.

[0005]

SUMMARY OF THE INVENTION To achieve the above object, the present invention provides a pump gate in which a pump for forcibly discharging water from an upstream waterway of a gate to a downstream waterway is integrally attached to the gate. A dust collector installed in the upstream waterway is integrally attached to the gate, and a dust receptacle is provided on the upper end surface of the gate.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described more specifically based on embodiments of the invention shown in the drawings. Here, FIG. 1 is a side view of a main part of a pump gate with a dust remover, FIG.
FIG. 2 is a front view of a main part of a pump gate with a dust remover.

In FIG. 1, a pump gate 1 with a dust remover is installed in a water channel 2 so as to cut off the water channel 2 in a transverse direction thereof. The pump gate 1 with a dust remover has a structure in which the water channel 2 is opened and closed by raising and lowering a gate 1a as a door body. The pump gate 1 with the dust remover raises the gate 1a during natural drainage and drains the water. During forced drainage, the pump 1 attached to the gate 1a is used with the gate 1a closed to utilize the upstream waterway 2a of the gate 1a. Of water is forcibly drained to the downstream water channel 2b. When the gate 1a moves up and down, the dust remover 7 also moves up and down integrally therewith.

On both left and right sides of the water channel 2 in which the pump gate 1 with the dust remover is installed, gate columns 3 are extended upward, and the left and right gate columns 3 are provided on the left and right ends of the gate 1a in the vertical direction. Are formed, and the gate 1a is structured to move up and down along the guide grooves. Rollers are provided at the left and right ends of the gate 1a to reduce sliding resistance with respect to the guide groove, so that when the gate 1a moves up and down, it can smoothly move up and down along the guide groove.

The lower ends of a pin rack bar 1b for raising and lowering the gate 1a are connected to the left and right upper ends of the gate 1a, respectively. The pin rack bar 1b is attached so as to mesh with a pinion (not shown) provided on the upper side of the gate post 3, and the pin rack is rotated by a drive motor (not shown) to pull up or down the pin rack bar 1b. Is moved up and down the gate 1a to which the lower end is connected.

A pump 4 is horizontally mounted on the lower surface of the gate 1a facing the upstream waterway 2a of the waterway 2 so as to pass through the gate 1a. Pump 4 is gate 1a
In the closed state, the water in the upstream waterway 2a of the gate 1a is forcibly drained toward the downstream waterway 2b. The pump 4 is mounted horizontally, and its suction port 4a is mounted in the upstream water passage 2a in a state of being oriented horizontally. The pump 4 is attached to the gate 1a such that the suction port 4a is at a height near the bottom of the water channel when the gate is fully closed.

A discharge port 4b of the pump 4 mounted through the gate 1a faces the downstream water passage 2b, and a flap gate 5 is mounted on the discharge port 4b. The upper end of the flap gate 5 is connected to the surface of the gate 1a on the side facing the downstream waterway 2b by a hinge structure 5a.

The flap gate 5 has a structure in which the hinge structure 5a rotates around the center of rotation and opens toward the downstream waterway 2b of the gate 1a, and closes toward the upstream waterway 2a of the gate 1a. The flap gate 5 is closed when the water pressure in the downstream water channel 2b is high to prevent backflow, and is opened by the water pressure of the discharge water discharged from the pump 4 when the pump 4 is forcibly drained, so that the water in the upstream water channel 2a of the gate 1a is opened. To the downstream waterway 2
b can be drained.

A drinking screen 6 is attached to the surface of the gate 1a facing the upstream waterway 2a. This drinking screen 6 is also located on the front side of the suction port 4a of the pump 4, and prevents dust from being sucked into the suction port 4a. The lower end of the drinking screen 6 slightly projects toward the upstream water channel 2a, and is slightly inclined.

The dust remover 7 is a device that scrapes up dust that has flowed onto the mouthpiece screen 6 and discharges the dust to a dust receptacle 8 provided on the upper end surface of the gate 1a. In this embodiment, the dust remover 7 is used. Numeral 7 has a rake-raising structure. The rake-scraping-type dust remover 7 includes, for example, a telescopic arm 7a, a rake claw 7b, a rake opening / closing cylinder 7d, and the like.

In this embodiment, the telescopic arm 7a can be extended and retracted in two stages, and a hydraulic cylinder for extension and contraction is provided inside. The telescopic arm 7a has a rake claw 7b at its lower end.
Is provided. The rake claw 7b is a screen 6 for drinking
The portion that directly scrapes the garbage that has landed on the surface has a comb-like shape.

The dust gathered between the rake claw 7b and the mouthpiece screen 6 is scraped up by the telescopic arm 7a extending and contracting, whereby the tip of the rake nail 7b moves up along the mouthpiece screen 6. And the gate 1a
Is discharged to the trash receptacle 8 provided on the upper end surface of the garbage.

The upper side of the telescopic arm 7a is rotatably connected to a horizontal tip of a support column 1c bent in an inverted L-shape by a horizontal rotary shaft 7c. Support pillar 1
The lower end of c is integrally fixed to the upper end surface of the gate 1a. The telescopic arm 7a is attached to the gate 1a via the support pillar 1c. The telescopic arm 7a rotates about this horizontal axis, and the rake claw 7b at the lower end thereof can come into contact with or separate from the drinking screen 6.

A lower end of a rake opening / closing cylinder 7d is connected to an upper portion of the horizontal portion of the support column 1c so as to be rotatable around a horizontal axis. The tip of the extendable cylinder rod of the rake opening / closing cylinder 7d is connected to the upper end side of the extendable arm 7a so as to be rotatable around a horizontal axis. The rake opening / closing cylinder 7d rotates the telescopic arm 7a to open / close the rake claw 7b, that is, moves the rake claw 7b away from or close to the drinking screen 6 side.

When the rake opening / closing cylinder 7d extends,
The rake claw 7b at the lower end of the telescopic arm 7a rotates in a direction approaching the drinking screen 6 with the upper rotation shaft 7c as a rotation fulcrum. When the rake opening / closing cylinder 7d contracts, the telescopic arm 7a pivots on the upper rotating shaft 7c and the rake claw 7b at the lower end of the rake pawl 7b engages the drinking screen 6.
Rotate away from the camera.

Next, the operation based on the configuration of the embodiment of the present invention will be described below. The gate 1a installed in the waterway 2 is raised for natural drainage. When the pinion (not shown) is driven to rotate, the pin rack bar 1b meshing with the pinion rises, and the gate 1a to which the lower end of the pin rack bar 1b is connected also rises.

An upper end of a telescopic arm 7a of a dust remover 7 having a lower end to which a rake claw 7b is connected is mounted on an upper end surface of the gate 1a via a supporting column 1c. When the gate 1a rises, the dust remover 7 also rises integrally. Similarly, when the gate 1a falls, the dust remover 7 also falls integrally.

Therefore, only by moving the gate 1a up and down, the dust remover 7 can be moved up and down at the same time, and a mechanism for moving the dust remover 7 up and down is not required.

The dust that has landed on the mouthpiece screen 6 on the side facing the upstream water channel 2a of the gate 1a is extended by extending the rake opening / closing cylinder 7d with the telescopic arm 7a of the dust remover 7 extended. The lower end of the telescopic arm 7a approaches the drinking screen 6 with the rotation shaft 7c as a pivot point,
The rake claw 7b connected to the lower end of the telescopic arm 7a has its claw tip in contact with the drinking screen 6.

In this state, when the telescopic arm 7a is reduced, the rake claw 7b moves upward in contact with the drinking screen 6, and the rising rake claw 7b is moved to the drinking screen 6.
Scrap up the garbage adhering to. Dust is raked between the upwardly moving rake claw 7b and the mouthpiece screen 6.

The rake claw 7b, which has moved up to the upper end of the mouthpiece screen 6, discharges the scraped dust to the dust receptacle 8 provided on the upper end face of the gate 1a. When the dust is discharged to the dust receptacle 8 by the raised rake claw 7b,
By extending the contracted telescopic arm 7a, the rake claw 7b moves down to the lower end of the drinking screen 6, and the same operation is repeated thereafter to remove dust deposited on the drinking screen 6. .

It should be noted that the present invention is not limited to the above embodiment of the present invention, and it is needless to say that various modifications can be made without departing from the spirit of the present invention. For example, the refuse receiver 8 can be a power-type conveyor in the above embodiment. Further, the dust remover 7 has been described in the case of the rake-scraping type structure, but is not limited to this.

[0027]

As is apparent from the above description, according to the pump gate with the dust remover according to the present invention, the pump for forcibly discharging the water in the upstream channel of the gate to the downstream channel is integrally mounted on the gate. In the pump gate, the dust remover installed in the upstream waterway is integrally attached to the gate, and the dust receiver is provided on the upper end surface of the gate, so that the dust remover can be raised and lowered only by raising and lowering the gate at the same time. This eliminates the need to separately raise and lower the dust remover in accordance with the gate, and eliminates the need for a mechanism for raising and lowering the dust remover. Further, the height of the dust remover can be made smaller than that of a dust remover having an elevating mechanism provided on a gate post, and the dust remover can be reduced in weight and size.
