Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic dam gate plates, and more specifically, to a hydraulic dam gate plate with an adjustable sealing pad. Background Art

[0002] Hydraulic dams are commonly used devices for controlling water flow in water conservancy projects. They are usually made of steel plates. They are opened and closed by hydraulic systems and can effectively regulate water flow to meet the needs of different water conservancy projects, such as flood control, irrigation and power generation. In the prior art, several groups of hydraulic dams are usually laid horizontally in river channels, dams and other locations for use. In order to improve the sealing effect at the gap between two groups of hydraulic dams, technicians will install rubber on the side of the gate of the hydraulic dam. However, the rubber sealing pads on the side of the gate will wear out with use, resulting in gaps between the rubber sealing pads installed on the sides of the two groups of hydraulic dam gates, resulting in poor water-blocking and sealing effects, affecting the actual effect of the hydraulic dam in regulating water flow.

[0027] A waterproof protection assembly 5, the waterproof protection assembly 5 comprises a waterproof cover 50, the side of the waterproof cover 50 is detachably mounted on the surface of the hydraulic dam gate plate 3;

[0028] The adjusting component 6 is arranged inside the waterproof cover 50. The adjusting component 6 includes a motor 61, a bevel gear 2 63, a threaded rod 64, a movable block 65, and a connecting plate 66. The side of the motor 61 is fixedly installed with the surface of the hydraulic dam gate plate 3, and the output end is fixedly connected with a bevel gear 1 62. The end of the bevel gear 2 63 is fixedly installed with the side end of the threaded rod 64, and the outer surface is meshed with the bevel gear 1 62. The inner surface of the movable block 65 is threadedly connected with the outer surface of the threaded rod 64, and the outer surface is slidably installed with the inner wall of the waterproof cover 50. The side of the movable block 65 close to the hydraulic dam gate plate 3 is fixedly installed with the end of the connecting plate 66. The side end of the connecting plate 66 is fixedly installed with the side of the sealing gasket 4, and the outer surface is slidably installed with the inner surface of the hydraulic dam gate plate 3.

[0029] By setting the bevel gear 2 63, the bevel gear 2 63, the threaded rod 64, the movable block 65, the connecting plate 66 and other structures are arranged in two groups inside the waterproof cover 50 with the axis of the bevel gear 1 62. During the rotation of the bevel gear 1 62, the two bevel gears 2 63 will rotate in the opposite direction, driving the two connected threaded rods 64 to rotate in the opposite direction, so that the movable blocks 65 therein are moved closer to or farther from each other, thereby achieving the effect of adjusting the position of the sealing gasket 4, and the auxiliary rod 67 is used to assist the sealing gasket 4 in moving.

[0030] It also includes an auxiliary component 7 which is arranged inside the sealing gasket 4 .

[0031] Among them, the waterproof protection component 5 also includes a mounting block 51, a U-shaped strip 52, and a drying box 53. The side of the mounting block 51 is fixedly mounted to the outer surface of the waterproof cover 50, and the middle part is bolted to the surface of the hydraulic dam gate plate 3. The end of the U-shaped strip 52 is fixedly mounted to the inner wall of the bottom of the waterproof cover 50. The drying box 53 is arranged at the bottom of the waterproof cover 50, and the outer surface is slidably mounted to the middle of the U-shaped strip 52.

[0032] Among them, the adjustment component 6 also includes a controller 60 and an auxiliary rod 67. The surface of the controller 60 is fixedly installed on the inner surface of the waterproof cover 50 and is electrically connected to the motor 61. The side end of the auxiliary rod 67 is fixedly installed on the side of the sealing gasket 4, and the outer surface is slidably installed on the inner surface of the hydraulic dam gate plate 3.

[0033] The auxiliary component 7 includes a pressure sensing plate 70, a spring 71, and a movable column 72.

One end of the spring 71 is fixedly connected with the surface of the pressure sensing plate 70, and the other end is fixedly connected with the surface of the movable column 72. The end of the movable column 72 is slidably installed with the inner surface of the sealing gasket 4. The pressure sensing plate 70 is electrically connected with the controller 60.

[0034] By setting the auxiliary component 7, since the two sets of auxiliary components 7 installed on the two sealing gaskets 4 close to the two sets of hydraulic dams are staggered, the side of the movable column 72 will contact the surface of the other opposite sealing gasket 4 and be squeezed to move toward the inside of the installed sealing gasket 4, squeezing the connected spring 71, and the spring 71 transfers the pressure to the pressure sensing plate 70.

[0035] There are four auxiliary components 7 , two of which are respectively arranged inside the two sealing pads 4 , and the positions of the two lateral auxiliary components 7 are staggered with each other.

[0036] The working process of the utility model is as follows:

[0037] During the use of the hydraulic dam, the sealing pads 4 on the side of one of the two groups of transversely arranged hydraulic dams will squeeze the staggered movable columns 72 to move toward the inside of the sealing pad 4 of the other hydraulic dam, so that the movable columns 72 squeeze the springs 71, the springs 71 contract and are compressed, and the pressure is transmitted to the pressure sensing plate 70, and the controller 60 electrically connected to the pressure sensing plate 70 records the pressure intensity when the sealing pads 4 are not worn at this time;

[0038] Afterwards, after the seal 4 is worn, the gap between the two adjacent seals 4 will become larger, so that the squeezed active column 72 moves toward the outside of the seal 4, so that the squeezed force strength of the spring 71 is reduced, and the pressure strength of the pressure sensing plate 70 connected to the spring 71 is reduced. The controller 60 detects the change of the pressure signal. At this time, the controller 60 controls the motor 61 to start, and the bevel gear 1 62 connected to the output end of the motor 61 rotates, driving the meshing bevel gear 2 63 to rotate, and driving the connected threaded rod 64 to rotate, so that the threaded movable block 65 moves laterally along the inner surface of the waterproof cover 50, and drives the connected connecting plate 66 to move laterally, so that the installed seal 4 moves and expands outward along the inner surface of the hydraulic dam gate 3 until the pressure strength of the pressure sensing plate 70 reaches the initially recorded parameter. Through the above structure, the position of the seal 4 on the side of the hydraulic dam gate 3 can be adjusted by controlling the controller 60 to avoid the generation of gaps between the seals 4 installed on the sides of the two groups of hydraulic dam gates, thereby improving the actual effect of regulating water flow of the hydraulic dam.

[0039] During use, the controller 60, motor 61 and other structures are waterproofed by the waterproof cover 50, and the side end of the waterproof cover 50 is bolted and fixed to the surface of the hydraulic dam gate plate 3 by the mounting block 51, and a drying box 53 is installed inside the chamber where the controller 60 is installed at the bottom of the waterproof cover 50. The drying box 53 adsorbs and dries a small amount of water vapor that penetrates into the waterproof cover 50, thereby improving the waterproof effect of the waterproof cover 50, and the drying box 53 is clamped in the groove formed by the U-shaped strip 52 and the inner wall of the waterproof cover 50, so that it can be easily replaced by the staff after a certain period of use, thereby improving the protection effect of electrical equipment or other parts.
