Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This proposal relates to a gate pump facility in which pumps are installed side by side on a lifting sliding door.

[0002]

[Prior art]

 In the conventional drainage pumping station, a pumping station 29 is installed in parallel with the water drainage channel 28 beside the natural drainage channel 28 partitioned by the river surface gate 25 and the switching gate 27 as shown in FIG. Normally, both gates 25 and 27 are opened to allow natural drainage from the inner water side to the outer water side (river surface). However, when the water level on the outside water side is high and the inside water side is low and it is reversed and natural drainage is not possible, the switching gate 27 is closed to prevent backflow of water and instead the pump is operated to perform forced drainage. It has become. For this reason, a vast site dedicated to the pump station, civil engineering foundation work, and significant structures are required. Therefore, multiple pumps are installed side by side on the lift door, and the pump pumps the water on the inside water side to the outside water to perform forced drainage, and lifts the door body to open the water channel to allow natural drainage. The sluice gate was developed (Japanese Patent Publication No. 56-5883). However, in carrying out this, since the pump level is relatively high from the waterway floor, the required submersion depth is deep during forced drainage, and it becomes difficult to lower the water level on the inner water side, so it is difficult to lower the water level on the outer water side. There was a problem that the water level difference (lift) from the water level decreased and the water was not drained sufficiently. Moreover, if the door is raised during natural drainage, the screen on the inner water side is left unattended and the smooth flow of water is impeded.

[0003]

[Problems to be solved by the device]

 In this plan, the water level on the inland water side is sufficiently lowered during forced drainage, and drainage is fully performed from the inland water side to the outwater side to improve forced drainage efficiency. The objective is to obtain a gate pump facility that does not hinder the flow of water.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present proposal is to install a pump in a door body that has both ends slidably fitted in the guide grooves of the gate and is movable up and down. In a waterway facility with a dust remover installed on the inner water side of the same waterway as the gate, the pump is supported near the waterway floor, and the dust remover is supported so that it can be lifted on the waterway. And a gate pump facility provided with a dust remover lifting device. A utility model registration claim according to claim 1 in which the pump is a vertical pump. A utility model registration claim in claim 1 in which the pump is a horizontal pump. The gate pump equipment described above is one in which the dust remover is supported so as to be able to move up and down about a horizontal axis at the upper end, and the lifting device connects the tip of the wire rope of the hoisting machine to the lower part of the dust remover. Scope of utility model registration request Constituted by the gate pumping equipment of claim wherein.

[0005]

[Action]

 Therefore, in the case of forced drainage, the door body 1 is lowered to close the water channel 6, and the dust remover 5 is lowered to be placed in the water channel 6, and the dust remover 5 is operated to remove the fallen matter caught on the water channel. At the same time, by operating the pump 2, the water on the inner water side can be pumped to the outer water side, and the water level on the inner water side can be lowered to near the waterway floor.

Since the suction port 3 of the pump 2 is opened close to the waterway floor 7 and the pump 2 is supported close to the waterway floor 7, not only the required submersion depth is sufficiently secured but also the water level on the inner water side is lowered. Therefore, it can be sufficiently drained to the outside water side. In addition, in the case of natural drainage, the dust remover 5 is stopped and the dust collector 5 is lifted up onto the water channel 6, and the door 1 is further raised to open the water channel 6.

[0007]

Embodiments Both ends of the door body 1 are slidably fitted in the guide grooves 14, 14 of the gates 13, 13, and an elevating rod 15 provided on the door body 1 is attached to the upper end beam portions of the gates 13, 13. The door body 1 can be moved up and down to open and close the water channel 6 by connecting to the lift drive device 16 provided. The door 1 thus constructed is provided with vertical or horizontal pumping pumps 2 and 2, the suction port 3 of the pump 2 is opened to the inner water side, and the discharge port 4 is provided to the outer water side. The suction port 3 is opened inside the pit 8 formed in the water channel floor 7 to lower the level position of the pump 2 and bring it closer to the water channel floor 7.

A dust remover 5 is provided on the inner water side (upstream side) of the same water channel 6 as the gates 13 and 13. The dust remover 5 is provided on a machine frame 17, and a scraper 19 is installed on a set of endless rotary chains 18 and 18. The scraper 19 scrapes up the falling matter above the water channel 6, and transfers it to the carry-out conveyor 20. Can be collected. The upper end of the machine frame 17 is rotatably supported on the waterway stationary machine frame 21 by the horizontal shaft 10, and can be moved up and down from the solid line position in FIG. 1 to the imaginary line position. This lifting is performed by a lifting device 9 that connects the tip of the wire rope 12 wound by a hoisting machine 11 (winch) provided on the water channel to the lower part of the machine frame 17.

Reference numeral 22 in the drawing is a cable reel, 23 is a check flap valve provided at the discharge port 4 of the pump 2, 24 is an outside water side (downstream side) underdrain, 25 is a river table gate, and 26 is Main waterway embankment, 27 in FIG. 4 is power distribution equipment, and 30 in FIG. 8 is a deceleration forward / reverse motor.

[0010]

[Effect of device]

 Since the present invention is configured as described above, the pump 2 provided in the door 1 can sufficiently lower the water level on the inner water side and sufficiently drain the water on the outer water side to improve the forced drainage efficiency. In the natural drainage, there is a benefit that the dust remover 5 can smoothly drain the water without obstructing the running water.
