Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gate with a built-in pump installed at a boundary between a waterway and a river.

[0002]

2. Description of the Related Art In a flood, the water in a river (outside water area) is prevented from flowing back into a water channel (inside water area), and the water in the inside water area and the outside water area is drained to discharge the water in the inside water area to the outside water area. 3 and 4 as gates with built-in pump installed at the boundary
And what is shown in FIG. 5 is known. The gate with a built-in pump has a concrete gate 4 constructed by a sluice column 2 erected on the water channel 1 and a floor member 3 laid laterally on the floor of the sluice 1. The front surface of the left and right sides of the water stop gate 5 is brought into contact with each other, and the left and right ends of the water stop gate 5 are slidably fitted into guide grooves 4A, 4A provided in the gate 4. The water stop gate door body 5 is supported by the lift gate 4 so as to be able to move up and down. The water stop gate door body 5 incorporates, for example, two gate pumps 6 and 6 formed by a horizontal axis pump. The lower end of the spindle 8 is integrally connected to the water stop gate door 5, and the upper end of the spindle 8 is connected to the gear box 10A.
And an opening / closing means 10 including an operating handle 10B and an electric motor (not shown).

[0003] In the above-mentioned configuration, the water in the upstream channel 1A in the channel 1 is operated by operating the gate pumps 6 and 6 with the discharge opening 7 of the gate 4 closed by the water stop gate 5. It is sucked in from the suction port 6A of the gate pumps 6, 6, and is discharged (drained) from the discharge port 6B to the downstream water channel 1B. In addition, by lifting the water stop gate door body 5 by the opening / closing means 10 and opening the discharge opening 7, the water flow 1 can naturally flow from the upstream water channel 1A to the downstream water channel 1B in the water channel 1. In the figure, reference numeral 9 denotes a flap valve, and the flap valve 9 prevents backflow from the downstream water passage 1B to the upstream water passage 1A.

[0004]

However, in the conventional gate with a built-in pump, an opening / closing means 10 is installed on the top floor 2A of the sluice column 2, and the output of the opening / closing means 10 is transmitted via a spindle 8 to a water stop gate. Since the water is transmitted to the door body 5 and the water stop gate door body 5 is raised and lowered to open and close the discharge opening 3, the opening / closing means 10 is largely exposed on the road surface. For this reason, the appearance of the installation location of the gate with a built-in pump is deteriorated, and there are problems that it becomes an obstacle.

[0005] Such a problem, as shown in FIG.
This can be solved by installing the opening / closing means 10 below the road surface GL. However, in the conventional opening / closing means 10,
When the water stop gate door body 5 is lifted up and the discharge opening 7 is opened, the spindle 8 projects greatly above the opening / closing means 10 corresponding to the lifting allowance of the water stop gate door body 5. In the gate with a built-in pump in which the opening / closing means 10 is installed below the road surface GL, the position of the top floor 2A needs to be deepened to a level that allows the spindle 8 to protrude from the road surface GL. For this reason, the installation depth of the gate with a built-in pump is deepened, and the construction cost for civil engineering is correspondingly increased. Further, since the opening / closing means 10 is installed in an inferior environment with a high humidity right above the water shutoff gate door body 5, particularly, electric parts incorporated in the electric motor which is a constituent member of the opening / closing means 10. And the life of the opening / closing means 10 may be shortened.

On the other hand, in the conventional gate with a built-in pump shown in FIGS.
The water stop gate door body 5 is supported by the gate 4 so as to be able to move up and down by slidably fitting into the guide grooves 4A, 4A provided in the door.
, And the sliding friction resistance when the discharge opening 7 is opened increases. For this reason, the opening / closing means 10 provided with a high-output electric motor is required, and there is a problem that the initial cost and the running cost of the gate with a built-in pump are increased.

Accordingly, the present invention provides a structure in which the opening / closing means is installed under a road surface, in which the installation depth can be reduced, the cost of civil engineering construction can be reduced, and the life of the opening / closing means can be extended. An object of the present invention is to provide a gate with a built-in pump that can reduce initial cost and running cost by reducing the frictional resistance when the gate door is lifted, thereby eliminating the need for a high-output motor.

[0008]

In order to achieve the above object, a gate with a built-in pump according to the first aspect of the present invention comprises:
In a pump built-in gate in which a discharge opening of a gate provided in a water channel is opened / closed by a raising / lowering movement of a water stop gate door body containing a pump, an opening / closing means for raising / lowering the water stop gate door body is provided with a toughness-mediated node. A pulley device comprising at least one pulley and a drive source for winding or unwinding the buckling material node are provided.

Further, in the gate with a built-in pump according to the second aspect of the present invention, at least a driving source of the opening / closing means is installed at a position separated from immediately above the water stop gate door.

Further, in the gate with a built-in pump according to the present invention, a rotor is rotatably mounted on both sides in a width direction of the water stop gate door body, and the rotor has a guide groove provided in the gate. It is fitted so that it can roll and contact.

According to the first aspect of the present invention, even if the water stop gate door is lifted to open the discharge opening, no other member projects above the opening / closing means. For this reason,
Since the installation position of the opening / closing means below the road surface can be made shallow, the installation depth of the gate with a built-in pump can be set shallow.

According to the second aspect of the present invention, at least the drive source of the opening / closing means can be installed at a position distant from a highly humid and poor environment directly above the water stop gate door.

According to the third aspect of the invention, it is possible to reduce the frictional resistance when the water stop gate door is lifted.

Embodiments of the present invention will be described below with reference to the drawings. The same parts as those in the conventional example are denoted by the same reference numerals, and the duplicated structure and description of the operation will be omitted. FIG. 1 is a longitudinal side view showing an embodiment of the present invention, and FIG. 2 is a plan view under a road surface in FIG. 1. In these figures, a pair of opening / closing means 10 for raising and lowering a water stop gate door 5 is provided. The vehicle includes pulley devices 11 and 11 and a drive source 12.

The drive source 12 includes a motor 15, a speed reducer 17 that reduces the speed of rotation of the motor 16 and outputs the same, a drive shaft 18 that rotates at a reduced speed by the output of the speed reducer 17, and a drive shaft 18. And a take-up / feed-out drum 19 rotatably installed at the end of the drum. Further, the base end of the wire rope 15 is fixed to the winding / unwinding drum 19, the tip end of the wire rope 15 is fixed to the lower surface of the top floor 2 </ b> A, and the drive source 12 stops water through the partition 20. It is installed in a position separated from immediately above the gate door body 5, that is, in the drive source accommodating chamber 21 constructed above the water channel 1 </ b> A on the upstream side.

On the other hand, on both sides in the width direction of the water stop gate door 5, rollers 2 having a horizontal axis divided into upper and lower portions are provided.

With such a configuration, when the electric motor 16 of the drive source 12 is started and the winding / unwinding drum 19 is rotated in the winding direction, the wire rope 15 is wound.
The take-up drum 19 is wound up, and the movable pulley 13 and the water stop gate door body 5 are lifted according to the winding amount, so that the discharge opening 7 can be opened. When the take-up / feed-out drum 19 is rotated in the feed-out direction with the discharge opening 7 in which the moving pulley 13 and the water stop gate door body 5 are lifted open, the wire rope 15 is wound up. The moving pulley 13 and the water stop gate door body 5 can be hung in accordance with the amount of extension, and the discharge opening 7 can be closed.

According to the gate with a built-in pump of the present invention, since the opening / closing means 10 is composed of the pair of pulley devices 11, 11 and the drive source 12, the water stop gate door 5 is lifted,
Even when the discharge opening 7 is opened, other members do not project above the opening / closing means 10. That is, when the discharge opening 7 is opened by being incorporated into the conventional opening / closing means 10 of a built-in pump equipped with a gear box 10A, an operating handle 10B, and an electric motor (not shown) shown in FIG. Spindle 8 protruding greatly above 10
Alternatively, a spindle cover 8A that covers the spindle 8
There is no other member such as For this reason, the opening / closing means 10

Is installed at a position separated from immediately above the water stop gate door body 5 via the partition wall 20. That is, the water stop gate door 5
Since it is installed in the drive source accommodating room 21 constructed above the water channel 1A on the upstream side, which is separated from the inferior environment with high humidity directly above, the electric motor incorporated in the electric motor 16, the speed reducer 17, and the like is provided. In addition to avoiding adverse effects on the parts, the life of the opening / closing means 10 can be prolonged, and the occurrence of a state in which opening / closing cannot be performed due to an electrical failure can be avoided, thereby improving reliability.

Further, the rollers 22, 22 rotatably mounted on both sides in the width direction of the water stop gate door body 5 are fitted into the vertical guide grooves 4A, 4A provided in the gate 4 so as to be able to roll and contact therewith. The frictional resistance when the water gate door body 5 is lifted is smaller than the conventional sliding frictional resistance. Therefore, the use of a high-output motor is not required, and the initial cost and the running cost can be reduced.

Further, the pulley device 11 is constituted by a double pulley having one moving pulley 13 and one constant pulley 14, but a single pulley constituted by only one constant pulley or one moving pulley and a plurality of constant pulleys is used. The pulley device 11 may be constituted by a double pulley provided or a double pulley provided with a plurality of moving pulleys and a plurality of constant pulleys. Further, a ring chain may be used instead of the wire rope 15.

[0022]

That is, according to the first aspect of the present invention, even if the water stop gate door is lifted to open the discharge opening, no other member projects above the opening / closing means. For this reason, since the installation position of the opening / closing means under the road surface can be made shallow, the installation depth of the gate with a built-in pump can be set shallow, and the cost of civil engineering construction can be reduced.

According to the second aspect of the present invention, at least the drive source of the opening / closing means can be installed at a position away from a highly humid and inferior environment directly above the water stop gate door body, so that electric power can be provided. It is possible to prevent the adverse effects on the common parts, prolong the life of the opening / closing means, and improve the reliability.

Further, according to the third aspect of the present invention,
Since the frictional resistance at the time of lifting the water stop gate door can be reduced, the use of a high-output motor is not required, and the initial cost and running cost can be reduced.
