CN2440058Y - Lintel water-stopping structure of arc-shaped sluice gate - Google Patents

Abstract

The utility model relates to a lintel water-stopping structure of an arc-shaped sluice gate, which belongs to the metal structure parts in water resources and hydropower engineering. A down-the-hole lintel water-stopping structure of an arc-shaped sluice gate is comparative complicated. To solve the problems that the second water-stopping structure of the existing lintel water-stopping structure of arc-shaped sluice gate can be easily torn up and has high requirements of manufacture and installation accuracy, the utility model provides a lintel water-stopping structure of an arc-shaped sluice gate, which has a novel structure and a reasonable and feasible design. In the structure, a set-up spring which can move along a guide post is additionally arranged on a movable hinge plate. When a supporting leg of an arc-shaped sluice gate is compressed and deformed in an application process, under the action of a compression spring and water pressure, a water-stopping rubber and a sluice gate panel are kept into a favorable water-sealing effect all the time.

Description

Curved gate lintel water-stop structure

The utility model belongs to the metal structure part of water conservancy and hydropower engineering. Arc gates are used to seal and block the inlet and outlet of water conservancy and hydropower projects.

The top water stop of the submerged arc gate is mostly located upstream of the arc surface, and there are two lintel water stop structures. There are many forms, but they are all one door leaf and one door slot embedded part. Among them, there is a water stop that uses the self-weight of the gate to compress the top water stop to prevent leakage when the door is closed. This kind of water-stop structure is relatively simple, but it is not easy to adjust its installation height to meet the requirements of tight water-stop for both the top and bottom water-stops, and the manufacturing and installation precision is high. In recent years, various parties are actively exploring new forms of water-stops .

The task of this utility model is to provide a kind of two water-stop rubbers placed on the same movable arm by adjusting the pre-pressure of the spring by bolts. , so as to achieve a satisfactory water-stopping effect.

Its solution is: pre-embed a fixed hinge plate on the door groove, make it link to each other with its movable hinge plate by the hinge shaft, also have adjusting bolt between two hinge plates, preload spring, connect rubber plate. Two water-stop rubbers are fixed on the movable hinge, the first one is "Ω" type rubber, and the second one is "P" type rubber.

Like this, when necessary, can adjust compression spring by bolt, make its two layers of rubbers contact well with the outer surface of arc gate panel. In the case of a small water head, the water stop effect can also be guaranteed. The utility model also has the advantages that the water-stop rubber has a certain floating property on the basis of the pre-compression amount of 2-3mm, so that the wear of the water-stop rubber is relatively reduced during the opening and closing process of the gate. It also has good adaptability to the compression deformation of the arc gate support arm and the installation error of the lintel embedded parts and the door body.

The further improvement of the utility model is that a compression spring is set between the fixed hinge and the movable hinge and can move along the direction of the guide column. Under the action of the spring and water pressure, the water-stop rubber and the panel have good contact.

The accompanying drawings describe an embodiment of the utility model.

Figure 1 is the section at the axis position of the arc gate, which shows the contact form between the panel and the water-stop rubber.

Figure 1 shows the curved gate panel ①, the "P" type rubber ②, and the "Ω" type rubber ③ through contact with the curved gate leaf panel ① to achieve the water-stop effect. The movable hinge ⑤ can be fine-tuned by adjusting the nut  The inclined angle of the hinge plate ⑤ enables the water-stop rubber to reach a suitable pre-pressure between it and the panel ①. Stage clip ⑩ is movable along the guide post ⑨ welded on the fixed hinge plate ⑥. The fixed hinge ⑥ is connected with the movable hinge ⑤ through the hinge shaft ⑧, and the movable hinge ⑤ can rotate around the hinge shaft ⑧. The flat rubber is connected to the structure of the fixed hinge plate ⑥ through the fastener ④, the movable hinge plate ⑤, and the fixed hinge plate ⑥ are pre-embedded in the second-stage concrete of the door slot through the anchor bolt ⑦.
