Problems solved by technology

The structure of the traditional door slot protection device needs to keep its top above the water surface due to installation or removal, so it has the characteristics of large structural height, large number of parts, and heavy weight. For example, each door slot protection device of Xiluodu Power Station The weight reaches 27t, the installation and removal are time-consuming and laborious, and must be installed from the top down

Embodiment 1

[0029] Embodiment 1: as figure 1 The door slot plug of a plane gate shown in the figure has a main structure of a box-shaped steel structure 1 with a movable guide slot on the surface corresponding to the main counter rail of the door slot, and the top of the slot plug has a top inclined surface 3 (inclination 50°), the rubber assembly 2 is used as a soft connection at the joint with the door slot, and a steel rope or steel strand 4 is arranged on the top surface of the box. Simultaneously, the casing is provided with flushing pipeline 5 (water pipeline). The two sides that the slot plug combines with the main rail of the door slot and the anti-rail have spacing guide grooves, corresponding to the main rail track or the side guide block 6 on the door slot.

[0030] The installation process of the slot plug is implemented as follows: 1. After the door slot is installed, install the side guide block of the slot plug at the bottom of the door slot; 2. After the slot plug is hoi...

Embodiment 2

[0032] Embodiment 2: as figure 1 The door slot plug of the plane gate shown in the figure has a box-shaped steel structure as the main structure, with an inclined surface (inclination 60°) on the top, and there is a movable block corresponding to the main anti-rail of the door slot on the slot plug, which is combined with the door slot The rubber plate is used as the soft connection, and the top surface of the box is equipped with steel ropes or steel strands. At the same time, the box body is provided with a water pipeline. The two sides of the slot plug combined with the door slot main rail and the anti-rail have limiting guide grooves corresponding to the main rail track or side guide blocks on the door slot. The installation process of the slot plug is as follows: 1. After the door slot is installed, install the plug side guide block at the bottom slot of the door slot; 2. Install the hoisting steel rope (or steel strand) and pipeline on the top of the slot plug; 3. Inst...

Embodiment 3

[0034] Embodiment 3: as figure 1 The door slot plug of the planar gate shown in the figure has a box-shaped steel structure as its main structure, with an inclined surface at the top, a rubber plate as a soft connection at the joint with the door slot, and a steel rope or steel strand on the top surface of the box. At the same time, the box body is provided with a ventilation pipeline. There is a permanent magnet on the side of the slot plug, which corresponds to the embedded steel structure surface of the door slot. The installation process of the slot plug is as follows: 1. Install hoisting steel ropes (or steel strands) and pipelines on the top of the slot plug; 2. After the door slot is installed, the slot plug is hoisted from the top or side and enters the door slot, and is attracted by permanent magnets. 3. Before the slot plug is lifted out, connect the water pipe or air pipe for underwater silting, and then use the lifting mechanism to lift the slot plug out of the d...

Abstract

The invention discloses a door slot plug and a dismounting method thereof. The slot plug includes a main body; a matching part, located at the side of the main body, which cooperates with the inner side of the door slot; and a guide part, which guides the discharge of materials on the top of the main body. The door slot plug of the present invention can be conveniently installed at the bottom of the door slot, and the sundries falling into the door slot can fall to the top of the slot plug and be led out by the guide parts without accumulating at the bottom of the door slot; , simply lift up or remove the slot plug from the side.

Description

technical field [0001] The invention belongs to the field of water conservancy and hydropower engineering construction, and relates to a slot plug used for overcurrent protection of a plane gate slot and an installation and removal process thereof. Background technique [0002] In water conservancy and hydropower projects, during the long-term operation of diversion tunnels or similar structures, due to the concave cross-sections at both ends of the gate slot of the plane gate, gravel or sediment often accumulates at the bottom of the gate slot, or is caused by severe erosion and swirl. The door slot is damaged. The previous door slot protection method is to install a steel structure in the door slot to prevent gravel from entering the door slot. Patent CN202936765U discloses a diversion and drainage structure to block the gate groove and fill the frame structure. This invention can prevent gravel from entering the gate groove. Silt deposits, making the structure itself dif...
