Background
In the domestic hydraulic and hydroelectric engineering, the rule is that an accident gate should be arranged on the upstream side of the working gate of the down-the-hole drain flow passage. The necessity of providing a service gate in front of an accident gate should also be studied for gates of high head and long spillway. The accident gate or the overhaul gate is usually a plane gate, the gate leaves of the accident gate or the overhaul gate are required to be disassembled and lifted out of the gate slot for overhaul, and most of the accident gates or the overhaul gates arranged on the upstream of the working gate at present are of shaft type or shore tower type structures to above the water surface so as to meet the requirement of overhaul after the gate leaves are lifted out, and the condition of large civil engineering investment exists. The conventional vertical shaft type gate structure shown in fig. 3, wherein the top of the vertical shaft of the planar gate needs to be arranged above the water retaining liquid level, so that the planar gate is convenient to disassemble and overhaul after the gate is lifted, and is used for installing a hoist part and the like, thereby resulting in larger corresponding construction work amount of concrete; and the risk of shaft deformation is easily brought to high shaft because of geological condition is unstable.
Disclosure of Invention
The invention solves the technical problems that: the door leaves of the accident gate or the access gate are required to be disassembled and lifted out of the door slot for access.
The technical scheme adopted for solving the technical problems is as follows: the plane gate system comprises a main gate and a horizontal gate, wherein the main gate comprises a main gate groove and a main gate blade, the main gate blade can move in the main gate groove, the horizontal gate comprises a horizontal gate groove and a horizontal gate blade, the horizontal gate blade can move in the horizontal gate groove, the horizontal gate groove is communicated with the main gate groove in an orthogonal and crossed mode, and the horizontal gate blade can extend into the middle part of the main gate groove to partition the main gate groove.
Further is: the main gate further comprises a main hydraulic mechanism for driving the main gate leaf.
Further is: the horizontal gate further comprises a horizontal hydraulic mechanism for driving the horizontal gate leaf.
Further is: the main gate is an accident gate, and a working gate is further arranged at the downstream of the accident gate.
The beneficial effects of the invention are as follows: according to the plane gate system, the corresponding horizontal gate is arranged, so that the main gate groove can be blocked by the horizontal gate, and the maintenance of the main gate leaf lifted above the horizontal gate is realized without lifting the main gate leaf above the water surface. The door leaf of the horizontal gate can be overhauled or disassembled after the main door leaf is closed. The main gate and the horizontal gate can be mutually used as the other side for overhauling to provide a water-free and pressureless condition; the problem that the door leaves need to be overhauled after being lifted out of the door slot through the high and large vertical shaft is avoided.

FIG. 2 is a schematic diagram corresponding to the maintenance state of the main gate;
FIG. 3 is a schematic view of an arrangement of a conventional shaft gate;
Marked in the figure as: the main gate 1, the main gate groove 11, the main gate vane 12, the main hydraulic mechanism 13, the horizontal gate 2, the horizontal gate groove 21, the horizontal gate vane 22, the horizontal hydraulic mechanism 23, the working gate 3, the runner 4, the plane gate 5 and the hoist part 6.
Detailed Description
The invention is further described below with reference to the drawings and the detailed description.
As shown in fig. 1 and 2, the planar gate system according to the present invention includes a main gate 1 and a horizontal gate 2, the main gate 1 includes a main gate slot 11 and a main gate leaf 12, the main gate leaf 12 is movable in the main gate slot 11, the horizontal gate 2 includes a horizontal gate slot 21 and a horizontal gate leaf 22, the horizontal gate leaf 22 is movable in the horizontal gate slot 21, the horizontal gate slot 21 is disposed in orthogonal cross communication with the main gate slot 11, and the horizontal gate leaf 22 is capable of extending into a middle portion of the main gate slot 11 to block the main gate slot 11.
The main gate 1 and the horizontal gate 2 of the invention can be used as the maintenance of each other to provide a water-free and pressureless condition. As shown in fig. 1, the main gate 1 is in a blocking state, the main gate blade 12 is used for blocking the flow channel 4, and the on-site on-line maintenance of the horizontal gate 2 can be performed at this time without detaching the horizontal gate blade 22 in the horizontal gate 2; of course, without losing generality, when the main gate leaf 12 is used for plugging the runner 4, the main gate leaf 12 can be simultaneously in sealing fit with the main gate groove 11, so that the situation that water leaks to the horizontal gate 2 through the main gate groove 11 to cause that the maintenance operation of the horizontal gate 2 cannot be performed is avoided. As shown in fig. 2, when the main gate 1 is in an open state and the main gate blade 12 is lifted, the horizontal gate blade 22 in the horizontal gate 2 seals and cuts off the main gate groove 11, and blocks water in the main gate groove 11 from passing, so as to provide a dry field maintenance condition for the lifted main gate blade 12; of course, without loss of generality, when the horizontal door leaf 22 seals and cuts off the main door slot 11, the horizontal door leaf should be in sealing fit with the main door slot 11 to prevent water leakage from causing failure of maintenance work of the main door leaf 12 part.
Without loss of generality, as shown in the drawings, after the horizontal door leaf 22 of the present invention extends into the middle of the main door slot 11 to partition the main door slot 11, the main door slot 11 should be divided into an upper accommodating area and a lower plugging area, wherein the accommodating area corresponds to the area corresponding to the lifting of the main door leaf 12, and the plugging area corresponds to the area when the main door leaf 12 is plugged by the gate. Under the above circumstances, the planar gate system of the present invention can perform maintenance on the main gate 1 on the main gate blade 12 and the accommodation area portion of the main gate groove 11, and cannot perform maintenance on only the plugging area portion of the main gate groove 11; meanwhile, the maintenance of the whole structure of the horizontal gate 2 can be realized.
Without loss of generality, the gate that is typically located furthest upstream of the flow passage 4 is an accident gate, while a working gate is provided downstream of the accident gate. Under the condition that an accident gate and a working gate are arranged at the same time, the main gate 1 is the accident gate, and the corresponding horizontal gate 2 corresponding to the accident gate is matched with the accident gate; and the working gate 3 is arranged downstream of the accident gate. Of course, for the maintenance of the working gate 3, only the accident gate is needed to plug the flow passage 4. In addition, in some cases, the gate located at the most upstream of the flow channel 4 is an inspection gate, and the main gate 1 according to the present invention is referred to as an inspection gate. Namely, the main gate 1 in the planar gate system of the present invention is the gate disposed at the most upstream of the flow channel 4.
In addition, without losing generality, the main gate 1 and the horizontal gate 2 can theoretically adopt various existing opening and closing driving structures for opening and closing the gate leaves, such as a conventional winch type opening and closing machine; referring to the drawings, the invention can respectively adopt a mode that a hydraulic driving mechanism drives corresponding door leaves to move in a door slot, and is correspondingly provided with a main hydraulic mechanism 13 for driving main door leaves 12; a horizontal hydraulic mechanism 23 is provided for driving the horizontal door leaf 22.
