[0001] The utility model relates to the field of hydropower and water conservancy projects, in particular to a water retaining and protective gate. Background Art

[0002] In the field of hydropower engineering in my country, water retaining protection gates are usually required to be installed in the tailwater surge chamber and the tailwater ventilation tunnel according to project needs to prevent unexpected situations.

[0003] At present, most of the sills of water-retaining gates are stepped. One is permanent, which is not conducive to the traffic conditions of the surge chamber and the vent hole; the other is detachable, that is, it is fixed with bolts, which is troublesome to use, and frequent disassembly will seriously affect the service life. Moreover, the above two types of water-retaining gates are opened and closed by rotating the door leaf, that is, the wheel on the door leaf rotates around the hinge fixed at one end.

[0004] The problems with the above two types of water retaining protection gates are:

[0005] Since the traffic conditions must be met at ordinary times, the sill at the outlet of the tailwater surge chamber in most projects is actually a slope structure, while the structure in which the wheels rotate around the hinge in the above-mentioned water retaining protection gate are not suitable for a slope structure. Utility Model Content

[0031] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the technical solution of the present utility model is further described below in conjunction with specific embodiments.

[0032] Combination Figures 1 to 6 As shown, the present embodiment is a water retaining protection gate, comprising a gate slot 1, a gate body 5, and a hinge structure. The bottom sill 9 of the gate slot 1 is a stepless slope structure. The gate body 5 is connected to the main rail of the gate slot 1 via the hinge structure. The hinge structure enables the gate body 5 to rotate in mid-air around the main rail of the gate slot 1 to open and close. The gate body 5 forms a single-door structure. A water seal assembly 7 is provided at the bottom of the gate body 5. The water seal assembly 7 is adapted to the slope of the bottom sill 9, so that when the gate body 5 is closed, the water seal assembly 7 can cooperate with the bottom sill 9 to form a closure.

[0033] In some embodiments, such as Figure 3As shown, the support hinge structure includes a fixed hinge 2, a movable hinge 4 and a hinge shaft 3. The fixed hinge 2 is welded on the main rail of the gate slot 1, and the movable hinge 4 is arranged on either side of the gate body 5. The fixed hinge 2 and the movable hinge 4 rotate and cooperate through the hinge shaft 3 to form a support hinge structure. Compared with the hinge structure, the support hinge structure has a better stress condition and can withstand a larger load. It can withstand the cantilever force of the gate body 5 suspended in the air, thereby realizing the gate body 5 suspended and rotating to open and close, so as to adapt to the slope structure of the bottom sill 9 of the gate slot 1. In this embodiment, the bottom sill 9 can be permanent and non-detachable. Compared with the traditional step-type bottom sill 9, it can meet the normal traffic conditions, does not need to be frequently disassembled, saves manpower and material resources, and effectively extends the service life of the bottom sill 9.

[0034] In some embodiments, the water retaining protection gate further includes a locking assembly 8 , which is disposed on the gate body 5 and the gate slot 1 , and is used to lock the closed gate body 5 .

[0035] Further, such as Figure 4 As shown, the locking assembly 8 includes a swing bolt, a pin shaft, a nut, a pin shaft seat plate and a locking seat plate. The pin shaft seat plate is welded and fixed to the side wall of the gate body 5. The pin shaft passes through the pin shaft seat plate and the swing bolt, so that the pin shaft seat plate is connected to the swing bolt through the pin shaft rotation. The swing bolt can rotate freely. The locking seat plate is welded and fixed on the secondary rail of the door slot 1, and the swing bolt can rotate until it is stuck in the hole of the locking seat plate. Specifically, a set of locking assemblies 8 are arranged on the primary rail and the secondary rail of the door slot 1.

[0036] When the gate body 5 is closed, rotate the swing bolt to clamp it into the hole of the locking seat plate, screw the nut onto the thread of the swing bolt, use a wrench to tighten the nut of the swing bolt, and lock the gate body 5. The gate body 5 can be closed and locked and the water seal assembly 7 can be compressed using a wrench, which has a certain labor-saving effect.

[0037] In some embodiments, such as Figure 5 and Figure 6As shown, water seal components 7 are provided on both sides and the bottom of the gate body 5, and the water seal components 7 on both sides and the bottom cooperate to form a U-shaped sealing structure. The water seal component 7 includes a side water seal 7001, a side water seal pressure plate 7002, a bottom water seal 7003 and a bottom water seal pressure plate 7004. The side water seal 7001 and the side water seal pressure plate 7002 are arranged on both sides of the gate body 5, and the bottom water seal 7003 and the bottom water seal pressure plate 7004 are arranged at the bottom of the gate body 5. Specifically, the bottom water seal pressure plate 7004 should be shorter than the bottom water seal 7003 by a certain distance to ensure that the bottom water seal pressure plate 7004 will not interfere with the bottom sill 9 when the gate body 5 is in a water-blocking and water-sealing state. The water seal component 7 at the bottom and the bottom sill 9 of the gate groove 1 adopt a slope structure with the same slope, and the water seal component 7 is in contact with the slope surface of the bottom sill 9 at least partially. On the basis of being parallel to the slope of the bottom sill 9, the water seal component 7 protrudes 2mm relative to the bottom sill 9. This ensures that the bottom sill 9 structure will not affect the traffic conditions when the gate body 5 is opened, and also ensures that when the gate body 5 is closed, the water seal assembly 7 at the bottom of the gate body 5 has a certain amount of compression, thereby achieving the bottom water sealing requirement when the gate body 5 is closed.

[0038] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
