Technical Field

[0001] The invention relates to the technical field of hydraulic gates, in particular to an in-line slope undercover gate. Background Art

[0002] At present, the main types of dams available are rubber dams, flap gates and undercover gates. Figure 1 As shown, for a river channel 70 with a deep gulf 73 and a river beach 72, a rubber dam with a flexible structure is generally used, and a gate pier is set at the slope change position. However, the strength of the rubber dam is low and the impact resistance is poor. In order to build a rigid gate on the slope surface, a Chinese invention patent with application number 201621378140.3 discloses an undercover gate, including a flat bottom gate and an inclined bottom gate. The inclined bottom gate includes an inclined bottom door leaf and an inclined axis arranged at the bottom edge of the inclined bottom door leaf. The inclined axis is arranged on the base of the slope surface, but the horizontal projection of the inclined bottom gate and the flat bottom gate are not in a straight line, which does not conform to the customary arrangement of the weir gate, and it can only be arranged at the foot of the slope (i.e., the intersection of the river beach 72 and the upper slope 75 of the river beach). When the river channel 70 has a deep gulf 73 and a river beach 72, it cannot be set at the top of the slope of the deep gulf of the river channel (i.e., the intersection of the river beach 72 and the lower slope 76 of the river beach).

[0025] Combination Figure 7 The cross universal joint 60 includes a fork shaft 1 61, a fork shaft 2 62 and a cross shaft 63. The fork shaft 1 61 and the fork shaft 2 62 are connected by the cross shaft 63. The fork shaft 1 61 is arranged on the horizontal base 10, and the fork shaft 2 62 is arranged on the slope base 20. The bottom edge of the flat bottom door leaf 30 is fixedly connected to the fork shaft 1 61, and the bottom edge of the sloped bottom door leaf 40 is fixedly connected to the fork shaft 2 62.

[0026] Combination Figure 4 The flat-bottom door leaf 30 has a flat-bottom door top corner α near the slope base 20, and the sloped-bottom door leaf 40 has a sloped-bottom door top corner β near the horizontal base 10. A hinge assembly 50 that can change shape is provided between the flat-bottom door top corner α and the sloped-bottom door top corner β. The hinge assembly 50 is composed of a first connecting plate 51 and a second connecting plate 52 that are hinged. The first connecting plate 51 and the second connecting plate 52 are both rigid triangular sheet plates. Specifically, the first side edge of the first connecting plate 51 and the first side edge of the second connecting plate 52 are hinged to form a rotation axis of the hinge assembly 50. The top corner of the first connecting plate 51 and the top corner of the second connecting plate 52 are hinged to form a hinge top corner γ of the hinge assembly 50. The hinge top corner γ changes shape with the hinge assembly 50. The opening and closing angle changes, the second side edge of the first connecting plate 51 is hinged to the side edge of the flat bottom door leaf 30, the second side edge of the second connecting plate 52 is hinged to the side edge of the slanted bottom door leaf 40, when the hinge assembly 50 is in a fully expanded state, the hinge assembly 50 is triangular, its top corner is facing downward, and its bottom edge is facing upward, the flat bottom door leaf 30 has a flat bottom door top corner α on the side close to the slope base 20, and the slanted bottom door leaf 40 has a slanted bottom door top corner β on the side close to the horizontal base 10, the flat bottom door top corner α of the flat bottom door leaf 30 and the slanted bottom door top corner β of the slanted bottom door leaf 40 are spliced ​​and connected by inserting the hinge top corner γ of the hinge assembly 50, and the flexible connection between the flat bottom door leaf 30 and the slanted bottom door leaf 40 is achieved by changing the angle of the hinge top corner γ.

[0027] Combination Figure 5As shown, when the gate unit 100 of the in-line slope bottom gate of this embodiment is completely lying on the top of the slope, the first connecting plate 51 and the second connecting plate 52 are folded inward. Under the action of the upstream water flow, if the first connecting plate 51 and the second connecting plate 52 are completely fitted, the two connecting plates will swing left and right. In order to increase the supporting force of the first connecting plate 51 and the second connecting plate 52, the angles of the top corners of the flat bottom gate leaf and the top corners of the inclined bottom gate leaf are designed to be slightly less than 90°, so that the first connecting plate 51 and the second connecting plate 52 will not be completely fitted when folded, forming a stable triangular support structure to avoid swinging left and right under the action of water flow. Specifically, the length and angle parameters of the flat bottom gate leaf 30, the inclined bottom gate leaf 40, the first connecting plate 51 and the second connecting plate 52 satisfy the following relationship:

[0028] Set the slope ratio of the slope surface at the top of the slope to 1:m, combined with Figure 1 In this embodiment, there are a total of four slope surfaces 90, and the slope m of each slope surface 90 can be different. Figure 8 As shown, if the gate height is set to h, then the side of the inclined bottom door leaf 40 connected to the first connecting plate 51 = the gate height h; then the length of the side of the inclined bottom door leaf 40 connected to the fork shaft 2 62 = h×(1+m 2 ) 0.5 ;

[0029] Combination Fig. 9 As shown, OB is an auxiliary line perpendicular to OG, OE is an auxiliary line perpendicular to OA; CBDEF are on the same horizontal line, ∠BOF is the second adjustment angle θ2; ∠DOE is the first adjustment angle θ1; in this embodiment, θ2 and θ1 are both set to 9°;

[0030] Then, the flat bottom door top angle α of the flat bottom door leaf 30, that is, ∠FOG = 90°-θ2;

[0031] The top angle β of the inclined bottom door leaf 40 is ∠AOD=arctan(m)-θ1;

[0032] The top corner of the first connecting plate 51 ∠DOC = the top corner of the second connecting plate 52

[0033] Combination Figure 4 and Figure 5 As shown, the gate unit 100 of this embodiment is at the top of the slope, and when discharging water, it is combined with Figure 5 and Figure 6The flat bottom door leaf 30 and the sloping bottom door leaf 40 completely lie on the horizontal plane 80 and the sloping surface 90, and the hinge assembly 50 composed of the first connecting plate 51 and the second connecting plate 52 folds inwards. The angle parameters of the sloping bottom door leaf 30, the flat bottom door leaf 40, and the first connecting plate 51 and the second connecting plate 52 are designed so that the first connecting plate 51 and the second connecting plate 52 will not be completely attached when they lie on the top of the slope. Figure 6 Specifically, the two sides of the hinge assembly 50 are supported on the horizontal plane and the slope surface and there is an angle between the two sides of the hinge assembly 50, so that the hinge assembly 50 forms a stable triangular support structure to prevent the first connecting plate 51 and the second connecting plate 52 from swinging left and right under the action of water flow. Figure 5 As shown, in the upright water-blocking state, the hinge assembly 50 is unfolded, the flat-bottom door leaf 51 and the inclined-bottom door leaf 52 and the hinge assembly 50 are all upright on the slope surface 90 of the river channel 70, and the Figure 2 and Figure 7 As shown, the horizontal projections of the flat-bottom gate leaf 30 and the inclined-bottom gate leaf 40 are on a straight line. Compared with the undercover gate disclosed in the application number 201621378140.3, the in-line arrangement of the flat-bottom gate leaf and the inclined-bottom gate leaf in this embodiment is more in line with the layout habits of the river gate.

[0034] Combination Figure 2 and Figure 3 and Figure 8 As shown, the gate unit 100 of this embodiment is arranged at the foot of the slope, combined with Figure 2 As shown, the horizontal projections of the flat-bottom gate leaf 30 and the inclined-bottom gate leaf 40 are on a straight line. Compared with the undercover gate disclosed in the application number 201621378140.3, the in-line arrangement of the flat-bottom gate leaf and the inclined-bottom gate leaf in this embodiment is more in line with the layout habits of the river gate.

[0035] Example 2

[0036] The structure of the gate unit 100 of the second embodiment is the same as that of the gate unit 100 of the first embodiment, except that the top angle α of the flat bottom door leaf 30 of the second embodiment is a right angle, that is, the first adjustment angle θ1=0°. Fig.10 As shown, OE is an auxiliary line perpendicular to OA; CBDE are on the same horizontal line, where the slope of the top of the slope is 1:m; in this embodiment, θ1 is set to 9°

[0037] Then, the top angle of the inclined bottom door leaf 40 ∠AOD=arctan(m)-θ1,

[0038] The top angle of the flat door leaf 30 is ∠BOG=90°;

[0039] The top corner of the first connecting plate 51 ∠DOC = the top corner of the second connecting plate 52
