Abstract
The utility model discloses a tail water maintenance gate for a power station. The tail water maintenance gate comprises a gate body and a gate groove of the gate body, wherein the gate body is provided with a panel and a water seal; the gate groove is arranged at a tail water pipe outlet and is provided with an lintel; the panel and the water seal are arranged at a tail water side; the lintel is arranged on a breast wall of the tail water side. The tail water maintenance gate has the beneficial effects that sewage is prevented from being injected into the tail water maintenance gate through the top of the gate, and water is prevented from flowing into the top of the gate, so that a gate unit side and the tail water side are avoided loosing water retaining effect due to two-side flat pressure; the waste slag is prevented from flooding into a beam grillage of the tail water maintenance gate, so that the self weight of the gate is prevented from being increased, and the gate is guaranteed to be opened and closed normally.
Description
Technical field
The utility model relates to a kind of tail water overhauling gate of power station, belongs to Hydraulic and Hydro-Power Engineering gate technical field.
Background technology
In existing power station, consider the demand of the maintenance hydraulic turbine, need to Emergency Gate be set at tailrace outlet, for the power station more than a unit, if consider generating by stages, when first unit generation, due to all the other unit Hot work in progress, therefore gate has the temporary water dash requirement, first unit will generate electricity and need to remove cofferdam, this will cause the meetings such as a large amount of slag stone and dirt to be poured in down a chimney under flow action into the tail sluice opening, the panel of conventional tail water overhauling gate, water seal and lintel all are arranged on the unit side, this can make a large amount of wastes pour in the Liang Geshang of tail water overhauling gate, cause the deadweight of gate to increase more, the keying of gate is more difficult, sometimes even can't open and close, so prior art is still perfect not.
Summary of the invention
The purpose of this utility model is to provide a kind of tail water overhauling gate of power station, can prevent that water from flowing into the lock top and making gate unit side and tail water side two sides concora crush lose the dash effect, prevent that waste pours in the Liang Geshang of tail water overhauling gate in maintenance simultaneously, can not increase the deadweight of gate, make the keying of gate normal.
The purpose of this utility model is achieved through the following technical solutions: a kind of tail water overhauling gate of power station, comprise a body and gate slot thereof, be provided with panel, water seal on described door body, described gate slot is provided with lintel, wherein, gate slot is arranged on the draft tube exit of tail water overhauling platform, and panel and water seal are arranged on the tail water side of tail water overhauling platform, and lintel is arranged on the breastwork of tail water overhauling platform.
Described breastwork is positioned at the tail water side of tail water overhauling platform.
The beneficial effects of the utility model are: the gate slot tail water side of (1), tail water overhauling gate arranges breastwork, gate slot passes on tail water overhauling platform, checking under water level, can prevent that dirt from pushing up and pouring into the tail water overhauling gate by lock, prevent that water from flowing into the lock top and making gate unit side and tail water side two sides concora crush lose the dash effect simultaneously; (2), panel and the water seal of tail water overhauling gate be arranged on the tail water side, when first unit generation removed cofferdam, can prevent that waste from pouring on the beam lattice of tail water overhauling gate increases the gate deadweight, makes the keying of gate normal.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
The partial enlarged drawing that Fig. 2 is regional K in Fig. 1.
Wherein: 1-door body, 2-gate slot, 3-panel, 4-water seal, 5-tail water overhauling platform, 6-lintel, 7-breastwork.
The specific embodiment
Further describe the technical solution of the utility model below in conjunction with accompanying drawing, but that claimed scope is not limited to is described.
As shown in Figure 1, Figure 2, a kind of tail water overhauling gate of power station, comprise a body 1 and gate slot 2 thereof, on described door body 1, is provided with panel 3, water seal 4; Be provided with lintel 6 on described gate slot 2, wherein, gate slot 2 is arranged on the draft tube exit of tail water overhauling platform 5, and panel 3 and water seal 4 are arranged on the tail water side of tail water overhauling platform 5, and lintel 6 is arranged on the breastwork 7 of tail water overhauling platform 5.
Described breastwork 7 is positioned at the tail water side of tail water overhauling platform 5.
Owing to having adopted technique scheme, the gate slot 2 of tail water overhauling gate door body 1 passes on tail water overhauling platform 5, checking under water level, can prevent that dirt etc. from pushing up by lock pours into the tail water overhauling gate, prevent that water from flowing into the lock top and making gate unit side and tail water side two sides concora crush lose the dash effect, in addition, panel 3 and the water seal 4 of door body 1 are arranged on the tail water side simultaneously, when first unit generation removed cofferdam, can prevent that waste from pouring on the beam lattice of tail water overhauling gate increases the gate deadweight.
Claims (2)
1. the tail water overhauling gate in a power station, comprise a body (1) and gate slot (2) thereof, it is characterized in that: on described door body (1), be provided with panel (3), water seal (4); Described gate slot (2) is arranged on the draft tube exit of tail water overhauling platform (5) and is provided with lintel (6), panel (3) and water seal (4) are arranged on the tail water side of tail water overhauling platform (5), and lintel (6) is arranged on the breastwork (7) of tail water overhauling platform (5).
