BACKGROUND OF THE INVENTION The present invention relates to a gate pump facility in which a pump is installed in parallel with a sliding door body.

[0002]

2. Description of the Related Art A conventional drainage station is a natural drainage channel 2 divided by a river surface gate 25 and a switching gate 27 as shown in FIG.
A pumping station 29 is installed beside 8 in parallel with the water channel 28. 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 exclusively for pumping stations, civil engineering foundation work, and important structures are required. Therefore, a plurality of 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 for forced drainage, and then 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 inland water level to a low level, so the outside water level is low. water level difference (lift) is reduced there problem not sufficiently drained of Ri and while a result smooth raising the door at the time of application hardly and natural drainage in lowland drainage inner aqueous side of the screen is left There is a problem that the flow of water is obstructed.

[0003]

[Problems to be Solved by the Invention] The present invention is capable of sufficiently lowering the water level on the inland water side during forced drainage, is suitable for lowland drainage, and drains sufficiently from the inland water side to the outwater side to improve forced drainage efficiency. Moreover, the purpose of the present invention is to obtain a gate pump facility in which the water flow is not obstructed by the dust flowing down from the upstream side during natural drainage.

[0004]

Merits order to achieve the above object, according to an aspect of the provided one horizontal pump door body vertically movable fitted slidably to both end portions in the guide groove of the gate, of the pump A waterway facility in which a suction port is provided on the inner water side, a discharge port is provided on the outer water side, and a dust remover is provided on the inner water side of the same waterway as the gate, and the pump is supported near the waterway floor, the dust eliminator is repatriation capable supported on waterways, and the horizontal axis of formed by providing the dust remover repatriation device gate pump equipment dust eliminator upper end portion
It is supported so that it can be raised and lowered around the
Do not connect the end of the machine's wire rope to the bottom of the dust remover.
It is composed of the gate pump equipment according to claim 1 of the utility model registration claim.

[0005]

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 falling matter caught in the water. By removing the water on the road and 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, the dust remover 5 is lifted on 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 used as an upper beam portion 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. Thus the water pumps second lateral type provided in the door 1 you, open to the inner water side suction port 3 of the pump 2,
The discharge port 4 is provided toward the outside water side. The suction port 3 is opened inside the pit 8 formed in the waterway floor 7 to lower the level position of the pump 2 and bring it closer to the waterway floor 7.

A dust remover 5 is disposed on the inner water side (upstream side) of the same water channel 6 as the gates 13 and 13. This dust remover 5
Is installed on the machine frame 17, and a scraper 19 is installed on a pair of endless rotary chains 18 and 18. The scraper 19 scrapes up the falling matter above the water channel 6, and carries it out.
Can be collected. The upper end of the machine frame 17 is rotatably supported by the on-channel fixed 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 virtual line position. This hoisting and hoisting machine 11 (winch) installed on the waterway

[0010]

[Effect of the Invention] Since the present invention is constructed as described above ,
One horizontal pump 2 provided on the door body 1 in a narrow waterway floor
This not only lowers the water level on the inner water side and allows sufficient drainage to the outer water side to improve the forced drainage efficiency, but also in the case of natural drainage, the dust remover 5 smoothly drains water without obstructing running water. There are benefits that can be made.
