Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.

Example 1

Referring to fig. 1 and 2, there is shown a novel gravity type split cross sliding gate structure including a gate sill 100, left and right gate bodies 200a and 200b, and an opening and closing device (not shown).

The gate sill 100 adopts a reinforced concrete empty box structure, and can also adopt a reinforced concrete bottom plate structure (an empty box is not arranged inside). The gate sill 100 may be based on geological conditions using pile foundations or other ground treatment.

The left and right gate bodies 200a, 200b are slidably disposed on the gate sill 100. In the present embodiment, the left and right shutter bodies 200a, 200b adopt a symmetrical arrangement structure, that is, the left and right shutter bodies 200a, 200b are completely symmetrical. However, in practical applications, the left and right gate bodies 200a, 200b may be asymmetric, for example, the gate body on the left bank has a small length, and the gate body on the right bank has a long length, and may be flexibly arranged according to the field situation.

Left and right slope rails 110a and 110b for supporting the left and right gate bodies 200a and 200b to slide are formed on the top surface of the gate sill 100, the left end of the left slope rail 110a extends into the left door storage 10a and is higher than the right end thereof, the right end of the right slope rail 110b extends into the right door storage 10b and is higher than the left end thereof, and the right end of the left slope rail 110a is butted with the left end of the right slope rail 110 b. The bottom surfaces of the left and right gate bodies 200a, 200b are fitted to the track surfaces of the left and right slope tracks 110a, 110b on the gate sill 100. Because the cross section of the natural river generally has a certain slope, the cross-pull gate in the embodiment adopts a slope type track, which is more favorable for reducing silting of the bottom sill of the gate. In addition, traditional cross-sliding gate is owing to adopt the vertical type section, in order to accomplish the transition of vertical type and river course slope, need set up longer linkage segment between lock chamber and the upper and lower stream river bottom, and the cross section of cross-sliding gate in this embodiment is close basically with the river course section, can greatly reduce the length of this linkage segment.

In the present embodiment, the left and right slope rails 110a and 110b are circular arc slope rails, and similarly, the bottom surfaces of the left and right shutter bodies 200a and 200b are also circular arc surfaces. The left and right slope rails 110a, 110b have a circular arc curvature that coincides with the circular arc curvature of the left and right shutter bodies 200a, 200b, as shown in fig. 1 and 2. The included angles between the left gate door body 200a and the right gate door body 200b and the horizontal line are different when the left gate door body 200a and the right gate door body 200b are at different positions, when the left gate door body 200a and the right gate door body 200b are in water retaining in the center of a river channel, the slopes of the left gate door body 200a and the right gate door body 200b are minimum, and at the moment, the downward sliding force generated by gravity is minimum. The higher the positions of the left and right shutter bodies 200a and 200b on the left and right slope rails 110a and 110b, the greater the slope thereof, and the greater the downward sliding force generated by gravity. Therefore, when the left and right gate bodies 200a and 200b start to slide down in the left and right door stores 10a and 10b, the slope is large, the sliding force of the left and right gate bodies 200a and 200b is large, and the sliding speed is high. When the left and right gate bodies 200a, 200b reach the center of the river, the slope is small, and the downward sliding force of the left and right gate bodies 200a, 200b is small, so that the stress when the left and right gate bodies 200a, 200b contact is small.

The opening and closing device is used for driving the left and right gate bodies 200a and 200b to open or close. The opening and closing device adopts a conventional opening and closing device, and the details are not repeated. When the gate needs to be closed to block water, the left gate door body 200a and the right gate door body 200b slide along the left slope track 110a and the right slope track 110b under the driving of the opening and closing device, the closing speed of the gate is accelerated by utilizing the downward thrust formed by the self weight, the opening and closing force is reduced, and even if the bottom sill 100 of the gate has certain siltation, the silt can be reopened under the action of the downward thrust and the opening and closing force of the opening and closing device.

The left and right gate bodies 200a, 200b adopt a floating box type gate structure, and the gravity generated by the left and right gate bodies 200a, 200b when water is not injected is greater than the buoyancy provided by the water body. The left and right shutter door bodies 200a and 200b are provided with water injection/drainage means for injecting or draining water into the left and right shutter door bodies 200a and 200 b. When the gate needs to be closed to retain water, the water injection and drainage equipment injects water into a plurality of floating boxes formed in the left gate door body 200a and the right gate door body 200b respectively so as to increase the dead weight of the left gate door body 200a and the right gate door body 200b, accelerate the gliding speed and improve the water retaining effect. When the gate needs to be opened to discharge water and needs to return to the door warehouse, the water stored in a plurality of buoyancy tanks formed in the left gate door body 200a and the right gate door body 200b is discharged by the water injection and drainage equipment respectively so as to reduce the self weights of the left gate door body 200a and the right gate door body 200b, so that the buoyancy tanks of the left gate door body 200a and the right gate door body 200b provide buoyancy to offset a part of gravity, at the moment, the gravity is still greater than the buoyancy, but the total gravity is greatly reduced, and then the left gate door body 200a and the right gate door body 200b are pulled back into the left door warehouse 10a and the right door warehouse 10b by the opening and closing equipment, so that the opening and closing force of the gate can be reduced due to the buoyancy provided by the buoyancy tanks formed in the left gate door body 200a and the right gate door body 200 b.

In addition, referring to fig. 3, a plurality of bottom traveling rollers 210a and 210b are provided on the bottom surfaces of the left and right gate bodies 200a and 200b at intervals in the length direction, so that the left and right gate bodies 200a and 200b travel along the left and right slope rails 110a and 110b and bear the weight of the left and right slope rails 110a and 110b, thereby further reducing the opening and closing force. The lower edges of the front and right sides of the left and right gate bodies 200a, 200b are respectively provided with a plurality of lateral catch wheels 220a, 220b at intervals along the length direction, and the lateral catch wheels are used as the support of water pressure in the water retaining or moving opening and closing processes of the left and right gate bodies 200a, 200 b.

Correspondingly, the bottom surfaces of the left and right gate bodies 200a ', 200 b' also adopt inclined planes, and in the scheme, the slopes of the left and right gate bodies 200a ', 200 b' are always kept at an angle.

Example 3

the left and right slope tracks 110a and 110b formed on the gate sill 100 "are horizontal tracks at the center of the river, and straight slope tracks at the rest. Correspondingly, the bottom surfaces of the left and right gate bodies 200a ", 200 b" are formed by combining and connecting a slope surface and a horizontal surface. When the left and right gate bodies 200a ', 200 b' are in the door storage, the horizontal plane is in a suspended state, so the length of the horizontal plane is not too long, and the left and right gate bodies 200a ', 200 b' are ensured not to incline towards the suspended direction.
