Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic gates, in particular to a hydraulic protection type steel gate structure. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. Water is a valuable resource that is indispensable to human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods and droughts, and regulate and distribute water to meet people's needs for water resources in life and production.

[0003] Steel gates are common hydraulic steel structures in water conservancy engineering facilities. When closed, they can block floods, prevent tides, store water and raise the upstream water level to meet the needs of upstream water intake or navigation. When open, they can discharge flood water, drain waterlogging, flush sand, take in water or adjust the flow rate according to the water use needs of the downstream. However, during the service life of current gates, their water-facing sides are eroded and corroded by the water flow, which can easily lead to damage to the gates. Moreover, since the current gates are directly connected to the opening and closing control system, the cost of replacing them is relatively high.

[0004] In summary, the utility model therefore provides a hydraulic protection type steel gate structure to solve the above-mentioned problems. Utility Model Content

[0022] The following is a further detailed description of the implementation of the present utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0023] like Figure 1-5 As shown, the utility model provides a hydraulic protection steel gate structure, including a steel gate body 1 and a protection plate 2, the protection plate 2 can be installed on the water-facing side of the steel gate body 1, so as to protect the steel gate body 1, a pair of connecting plates 3 are symmetrically arranged at the top and bottom of one side of the protection plate 2, and a through-limiting groove 4 is opened on the connecting plate 3, a pair of connecting grooves 5 are opened at the top and bottom of the steel gate body 1, an installation groove 6 is opened inside the steel gate body 1, and a movable block 7 is also installed at the top and bottom of the inner side of the installation groove 6, respectively, and the two movable blocks 7 are separated from each other on one side. A pair of limit blocks 8 are symmetrically arranged, and the two pairs of limit blocks 8 are respectively inserted into the two pairs of connecting grooves 5. A threaded rod 9 is installed between the two movable blocks 7 inside the installation groove 6. A moving block 10 is mounted on the surface of the threaded rod 9. A pair of connecting rods 11 are symmetrically installed on the top and bottom of the moving block 10, and the two pairs of connecting rods 11 are respectively connected to the adjacent movable blocks 7. Both ends of the connecting rod 11 are rotatably connected to the movable blocks 7 and the movable blocks 10. The movable block 7 is pulled or pushed by the connecting rod 11, so that the limit block 8 leaves the connecting groove 5, or the limit block 8 enters the connecting groove 5.

[0024] The moving block 10 is threadedly connected to the threaded rod 9 , and the rotation of the threaded rod 9 can drive the moving block 10 to move, thereby pulling or pushing the connecting rod 11 .

[0025] Among them, the position of the connecting plate 3 corresponds to the position of the connecting groove 5 one by one, and the shapes and sizes are adapted. The width of the limiting groove 4 is equal to the width of the limiting block 8, and the length of the limiting groove 4 is greater than the thickness of the limiting block 8, so that when the limiting block 8 is located in the limiting groove 4, the protective plate 2 still has a certain amount of space for movement, thereby facilitating the buffering effect of the rubber strip 12 to take effect.

[0026] Among them, the water-facing sides of the protective plate 2 and the steel gate body 1 are both arched and matched in shape. The arched protective plate 2 can unload force to both sides, so that the protective plate 2 has higher structural stability. The arched water-facing side of the steel gate is convenient for fitting with the protective plate 2. The arched back-water side array of the protective plate 2 is installed with multiple rubber strips 12. After the protective plate 2 is installed on the steel gate body 1, the rubber strips 12 are located between the protective plate 2 and the steel gate body 1. Through the rubber strips 12, the impact force of the water flow on the protective plate 2 will not be directly transmitted to the steel gate body 1, thereby reducing the damage to the steel gate body 1.

[0027] Among them, the protective plate 2 is made of wear-resistant steel plate, which has good wear resistance and high impact resistance, can effectively resist the erosion and corrosion of water flow, and is coated with an anti-corrosion coating on the surface to improve the corrosion resistance of the protective plate 2.

[0028] Among them, a hand wheel 13 is rotatably installed on the backwater side of the steel gate body 1, and the hand wheel 13 is transmission-connected with the threaded rod 9, so that the hand wheel 13 can drive the threaded rod 9 to rotate.

[0029] Among them, two guide rods 14 are symmetrically arranged inside the installation groove 6. The two guide rods 14 both penetrate the two movable blocks 7, and the movable blocks 7 are slidingly connected to the guide rods 14. The movable blocks 7 can only move along the surfaces of the guide rods 14, thereby improving the stability of the movement of the movable blocks 7.

[0030] Specific working principle:

[0031] The utility model prevents the water flow from directly impacting the steel gate body 1 by setting a protective plate 2 on the water-facing side of the steel gate body 1, thereby reducing the corrosion and scouring caused by the water flow to the steel gate body 1. At the same time, since the protective plate 2 is arched, it can well unload the impact of the water flow to both sides, while improving the structural stability of the protective plate 2 and extending the service life of the protective plate 2. A rubber strip 12 is installed on the inner side of the arched protective plate 2 on the water-facing side of the gate. The rubber strip 12 is located between the steel gate body 1 and the protective plate 2 to buffer the impact of the water flow on the protective plate 2, reduce the impact force transmitted to the steel gate body 1, and further reduce the damage caused by the water flow to the steel gate body 1. The corrosion resistance of the protective plate 2 is improved by coating an anti-corrosion coating on the surface of the protective plate 2, thereby further improving the service life of the protective plate 2. Finally, when the protective plate 2 is damaged and needs to be replaced, it is only necessary to turn the handwheel 13 to drive the threaded rod 9 to rotate through the handwheel 13, and the threaded rod 9 rotates to drive the moving block 10, and the moving block 10 pulls each connecting rod 11 to make the two movable blocks 7 approach the moving block 10, thereby pulling the limit block 8 out of the connecting groove 5, and then the damaged protective plate 2 can be removed from the steel gate body 1 and replaced with a new protective plate 2, and then the handwheel 13 is rotated in the opposite direction to make each limit block 8 re-enter the connecting groove 5 and even the limit groove 4 to complete the replacement of the protective plate 2, making the replacement of the protective plate 2 more convenient.
