[0029] Reference Figure 1-4 ,

[0030] A water gate with good water tightness comprises: a gate 1, a sealing belt 2 and a first guide rail 3. The gate 1 is made of Q235B steel, which is easy to stamp and weld. The gate 1 moves back and forth longitudinally under the action of an external support to open and close the waterway. Specifically, the external motor drives the external pulley block, and the external pulley block drives the gate 1 to move longitudinally. The sealing belt 2 is fixed to the two side ends of the gate 1 by bolts in the longitudinal direction, and the length of the sealing belt 2 is the same as the height of the gate 1. Two first guide rails 3 are provided, and the lower ends of the two first guide rails 3 are respectively cast on both sides of the waterway by concrete. The first guide rail 3 forms a first guide surface 4, and the length direction of the first guide surface 4 is perpendicular to the ground. The sealing belt 2 abuts against the first guide surface 4, and the sealing belt 2 fills the gap between the side end of the gate 1 and the first guide rail 3 to achieve sealing between the side end of the gate 1 and the first guide rail 3.

[0031] Specifically, the projection of the sealing belt 2 on the ground is a rectangle with two circles connected at each end, the rectangle is separated from the first guide surface 4, and the two circles are tangent to the first guide surface 4. That is, two contact lines are formed between the sealing belt 2 and the first guide rail 3 to improve the sealing effect of the sealing belt 2 on the gap between the gate 1 and the first guide rail 3.

[0032] Specifically, the sealing belt 2 is made of flexible material, specifically V45 rubber that has undergone water-stopping processing. There is mutual extrusion between the sealing belt 2 and the first guide rail 3, so that the sealing belt 2 produces elastic deformation to increase the contact area between the sealing belt 2 and the first guide rail 3, thereby further improving the sealing effect of the sealing belt 2.

[0033] Specifically, it also includes: an auxiliary wheel 5 and a second guide rail 6. The auxiliary wheel 5 is made of Q235B steel and has a certain elongation, strength and good toughness. Four auxiliary wheels 5 are provided, and the four auxiliary wheels 5 are divided into two groups and placed on both sides of the gate 1. Two second guide rails 6 are provided, and the lower ends of the two second guide rails 6 are respectively cast on both sides of the waterway by concrete. The gate 1 forms a water-facing surface 7 and a water-receiving surface 8, the auxiliary wheel 5 and the water-receiving surface 8 are rotatably connected by a rotating shaft, the sealing belt 2 and the water-facing surface 7 are fixedly connected by bolts, and the second guide rail 6 forms a second guide surface 9, and the second guide surface 9 is in the same plane as the first guide surface 4. Since the sealing belt 2 is flexible, when the water in the waterway impacts the gate 1, the gate 1 will shake to both sides of the gate 1, so that the curved surface of the auxiliary wheel 5 approaches and moves away from the second guide surface 9, and the distance between the two varies between 0-10mm. When the distance between the curved surface of the auxiliary wheel 5 and the second guide surface 9 is 10mm, the compression degree of the sealing belt 2 on the first guide surface 4 is the smallest. When the distance between the curved surface of the auxiliary wheel 5 and the second guide surface 9 is 0 mm, that is, when the auxiliary wheel 5 contacts the second guide surface 9, the compression degree of the sealing belt 2 on the first guide surface 4 reaches the maximum, and the sealing belt 2 is no longer compressed further, which is used to prevent the sealing belt 2 from being over-compressed and reducing its service life. At this time, when the gate 1 is moved longitudinally, the auxiliary wheel 5 can also roll along the second guide surface 9 to guide the gate 1.

[0034] Specifically, it also includes: a guide wheel 10. The guide wheel 10 is cast from Q235B steel and has a certain elongation, strength and good toughness. Four guide wheels 10 are provided, and the guide wheels 10 are evenly divided into two groups, and the two groups of guide wheels 10 are placed on both sides of the gate 1. The guide wheel 10 is rotatably connected to the side of the gate 1 through a rotating shaft, and the axis of the guide wheel 10 is perpendicular to the axis of the auxiliary wheel 5. The second guide rail 6 also forms a third guide surface 11, and the third guide surface 11 is perpendicular to the second guide surface 9, and the third guide surface 11 is perpendicular to the ground. The guide wheel 10 contacts the third guide surface 11. When the motor drives the pulley block, and the pulley block drives the gate 1 to move longitudinally, the guide wheel 10 rolls longitudinally along the third guide surface 11 to guide the gate 1. Prevent sliding friction between the gate 1 and the second guide rail 6 to increase the resistance to the longitudinal movement of the gate 1.

[0035] Specifically, the second guide rail 6 includes: an angle iron 12, an I-beam 13 and a connecting plate 14. An outer surface of the angle iron 12 forms the second guide surface 9, another outer surface of the angle iron 12 forms the third guide surface 11, a base of the I-beam 13 is welded and fixed to an inner surface of the angle iron 12 opposite to the third guide surface 11, another base of the I-beam 13 is welded and fixed to one side of the connecting plate 14, and the other side of the connecting plate 14 is welded and fixed to the other inner surface of the angle iron 12. A triangular connection relationship is formed between the angle iron 12, the I-beam 13 and the connecting plate 14, the structure is relatively stable, and the production is relatively simple.

[0036] Specifically, a lifting lug 15 is formed at the upper end of the gate 1 , and an external pulley block is hung on the lifting lug 15 to pull the gate 1 .

[0037] Specifically, a plurality of reinforcing ribs are respectively provided on the water-facing surface 7 and the water-receiving surface 8 of the valve, so as to improve the structural strength of the gate 1 and enhance the resistance to water flow impact.

Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept.
