Description

Technical Field

[0003] Patent publication number CN215715091 U discloses a valve for hydraulic engineering projects. This patent utilizes an auxiliary support mechanism to provide support for the gate plate.

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] like Figure 1 and Figure 5As shown in the figure, the utility model provides a waterproof and drainage device for water conservancy project construction, which is used to achieve waterproofing and drainage during the construction of water conservancy projects. The specific structure includes a sluice dam 1, a gate plate 2, a lifting mechanism, a diagonal brace 3 and a stop component. Among them: The sluice dam 1 is made of concrete structure, and inclined climbing seats are fixedly connected to both ends of the top of the sluice dam 1. The gate plate 2 is vertically slidably connected to the sluice dam 1, which is used to adjust the water flow at the sluice dam 1 and control the water levels upstream and downstream. When the gate plate 2 moves to the lowest position, the upstream water cannot enter the downstream at this time, and the waterproof effect can be achieved; on the contrary, when the gate plate 2 is lifted, the upstream water can smoothly enter the downstream at this time, and the drainage effect can be achieved. A lifting mechanism is installed on the sluice dam 1. The lifting mechanism can be selected from structures such as a hoist and an electric telescopic push rod. The lifting mechanism is used to lift and lower the gate plate 2. The diagonal brace 3 is always in an inclined state, that is, there is an included angle between the diagonal brace 3 and the gate plate 2. One end of the diagonal brace 3 is hinged to the side wall of the gate plate 2. The stop component is fixedly installed on the sluice dam 1 and is located on the downstream side of the gate plate 2; when the gate plate 2 moves to the bottommost position, the stop component can stop the other end of the diagonal brace 3.

[0042] Optionally, multiple diagonal braces 3 are provided on the same gate plate 2, and the multiple diagonal braces 3 are fixedly connected by a connecting rod 5.

[0043] Preferably, in combination with reference to Figure 2 , the stop component includes a slide rail 6 and a blocking member. The slide rail 6 is fixedly connected to the upper surface of the bottom plate of the sluice dam 1, and the slide rail 6 is located on the downstream side of the gate plate. The slide rail 6 is of a "U" - shaped structure. The slide rail 6 is preferably made of channel steel, and the notch of the channel steel faces upward. The channel steel is fixed to the bottom plate of the sluice dam 1 by expansion bolts. The other end of the diagonal brace 3 is selectively slidably connected to the slide rail 6. The blocking member is fixedly connected to the middle of the slide rail 6, and the blocking member selectively blocks the other end of the diagonal brace 3.

[0044] Preferably, a pulley 4 is rotatably connected to the other end of the diagonal brace 3, and the pulley 4 is selectively slidably connected to the slide rail 6. By setting the pulley 4, the other end of the diagonal brace 3 can pass through a smaller depression, so that the other end of the diagonal brace 3 can smoothly slide to the blocking member.

[0045] The blocking member is a blocking rod 8 and / or a blocking plate 7. Optionally, the blocking member is a blocking plate 7 and a blocking rod 8. The blocking plate 7 is inclined upward in the direction close to the gate plate 2. The blocking plate 7 is fixedly connected to the inner side wall of the slide rail 6.

The blocking rod 8 is fixedly penetrated through the two side walls of the slide rail 6, and the blocking rod 8 is fixedly connected to the side of the blocking plate 7 away from the gate plate 2.

The end of the limit rod 9 away from the gate plate 2 is fixedly connected to a first retaining ring 10, and an elastic member 11 is provided between the first retaining ring 10 and the diagonal support rod 3. The elastic member 11 is used to drive the other end of the diagonal support rod 3 to rotate toward the gate plate 2. When the gate plate 2 falls to a lower height, the water flow passing under the gate plate 2 will increase. Under the impact of the water flow, the other end of the diagonal support rod 3 may be located above the blocking plate 7. The elastic member 11 designed above drives the other end of the diagonal support rod 3 to rotate toward the gate plate 2. When the gate plate 2 falls to a lower height, the other end of the diagonal support rod 3 can ensure that the pulley 4 is slidably connected to the bottom plate of the dam 1 and the slide rail 6.

[0047] Preferably, a second retaining ring 12 is fixedly connected to the middle of the limiting rod 9. The second retaining ring 12 is located on the side of the diagonal support rod 3 close to the gate plate 2.

The elastic member 11 is a compression spring, which is sleeved on the circumference of the limit rod 9, and the two ends of the compression spring are respectively connected to the first retaining ring 10 and the second retaining ring 12.

[0049] Preferably, in conjunction with reference Figure 3-4 The lifting mechanism includes a screw rod 14, a hollow cylinder 15, an internally threaded sleeve 16, and a drive assembly.

The interior of the hollow cylinder 15 is rotatably connected to the internally threaded sleeve 16 via a bearing (not shown in the figure). The internally threaded sleeve 16 is threadedly connected to the screw rod 14. The drive assembly is used to drive the internally threaded sleeve 16 to rotate.

[0050] Preferably, the drive assembly includes a first support base 17, an intermediate shaft 18, a first intermediate gear 19, a second intermediate gear 20, a second support base 21, a driving shaft 22, a driving gear 23, a handwheel 24, and a driven gear 25. Specifically, a plurality of first support bases 17 are provided, and the plurality of first support bases 17 are fixedly connected to the top of the dam 1. The intermediate shaft 18 is rotatably connected in the first support base 17. The first intermediate gear 19 and the second intermediate gear 20 are splined on the intermediate shaft 18. The first intermediate gear 19 and the second intermediate gear 20 are coaxially rotatably connected. The second support base 21 is fixedly connected to the top of the gate plate. The driving shaft 22 is rotatably connected in the second support base 21. The driving shaft 22 is splined on the driving gear 23 and is fixedly connected to the handwheel 24. The driving gear 23 meshes with the first intermediate gear 19. The driven gear 25 is coaxially fixedly connected to the circumference of the internal threaded sleeve 16 and meshes with the second intermediate gear 20.

[0051] In a specific embodiment of the present invention, the intermediate shaft 18 and the driving shaft 22 are arranged perpendicularly, and the first intermediate gear 19, the second intermediate gear 20, the driving gear 23, and the driven gear 25 are all bevel gears. The transmission ratio between the driving gear 23 and the first intermediate gear 19 is greater than 1. Similarly, the transmission ratio between the second intermediate gear 20 and the driven gear 25 is also greater than 1. The transmission between the driving gear 23 and the first intermediate gear 19, and between the second intermediate gear 20 and the driven gear 25, all adopt a speed reduction and torque increase transmission mode.

[0052] By turning the handwheel 24, the intermediate shaft 18 and the driving gear 23 are driven to rotate, and then the first intermediate gear 19 is driven to rotate, and the power is transmitted to the second intermediate gear 20 through the intermediate shaft 18, and the power is again transmitted to the driven gear 25 through gear meshing, and the internal threaded sleeve 16 is driven to rotate. During the rotation of the internal threaded sleeve 16, since the screw rod 14 is threadedly connected to the internal threaded sleeve 16, it can drive the screw rod 14 to rise or fall, thereby driving the gate plate 2 to rise or fall.
