[0002] It is known that the gate is a control facility for closing and draining a passage, and the gate is an important component of a hydraulic structure, in a water conservancy project, it can close the orifice of the structure according to needs, and also can open the orifice wholly or partially, for adjusting the water level and flow of upstream and downstream, so as to obtain the benefits of flood control, water supply and power generation, and also can be used to intercept water flow, adjust flow, discharge silt and floating objects etc., cast iron gate is usually arranged at the water inlet and water outlet of water intake and water delivery structure, and the gate is flexibly and reliably opened and closed to play its function and benefit and maintain the safety of the structure, when the flood season comes, the water level of the reservoir rises, and the high water level will cause irreparable loss to the dam, and the gate needs to be opened to discharge flood to keep the water level at a certain height.
[0003] In the existing flood prevention intercepting gate, a sealing strip is used for sealing between the mounting frame and the gate plate. However, in actual use, the gate plate needs to move up and down during work, and the relative movement between the gate plate and the mounting frame will continuously rub the sealing strip. Frequent rubbing is easy to cause wear of the sealing strip, and with the passage of time, not only the normal aging phenomenon will appear, but also the wear caused by the movement of the gate plate will accelerate the damage. When the wear degree is more serious, the sealing effect of the gate is greatly reduced, and water flow cannot be effectively blocked, and the actual service life of the sealing strip and even the entire gate is shortened, which seriously affects the effect of flood prevention work.

[0017] (III) Beneficial Effects
[0018] Compared with the prior art, this utility model provides a gate with an interception structure for flood control in a reservoir, which has the following beneficial effects:
[0019] This invention relates to a flood control gate for reservoirs equipped with an interception structure. A movable baffle plate is installed on the water-facing side of the gate, and a sealing strip is placed on the baffle plate's end face facing the gate. Water pressure forces the sealing strip tightly against the gap between the baffle plate and the mounting frame. When the gate moves up and down, the sealing strip, traditionally installed directly between the gate and the mounting frame, suffers severe frictional wear due to the relative movement. Because the baffle plate is movable, it can buffer the impact of the gate's movement on the sealing strip to a certain extent. During gate movement, the friction between the baffle plate and the gate is not rigid, significantly reducing the frictional force on the sealing strip from the gate's movement, thereby greatly reducing wear. Under the same usage conditions and time period, the sealing strip in this patent does not need to be replaced as frequently as in traditional designs, effectively extending the sealing strip's service life.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figures 1-6 This utility model discloses a flood control gate for a reservoir equipped with an interception structure, comprising a gate plate 2 and a mounting frame 1 for mounting the gate plate 2. A connecting assembly 13 for connecting ropes is fixedly mounted on the gate plate 2. A water-retaining plate 3 is mounted on the water-facing side of the gate plate 2. The gate plate 2 and the water-retaining plate 3 are connected by a connecting shaft 5 and a connecting piece 6. The connecting piece 6 and the connecting shaft 5 are slidably connected. The connecting shaft 5 is fixedly mounted on the mounting frame 1, and the connecting piece 6 is fixedly mounted on the gate plate 2. A stop block 7 is provided at the end of the connecting shaft 5 to prevent the connecting piece 6 from detaching from the connecting shaft 5. In this configuration, the water-retaining plate 3 will not move up and down with the gate plate 2. For ease of description, this configuration will be used as an example below. Alternatively, the connecting shaft 5 can be fixedly mounted on the gate plate 2, in which case the water-retaining plate 3 will move up and down with the gate plate 2. The water-retaining plate 3 can also be hinged to the mounting frame 1 or the gate plate 2.
[0029] A sealing strip 4 is installed on the end face of the baffle plate 3 facing the gate plate 2. The width of the sealing strip 4 is greater than the width of the gap between the gate plate 2 and the mounting frame 1. The baffle plate 3 is subjected to water pressure, which causes the sealing strip 4 to be squeezed into the gap between the gate plate 2 and the mounting frame 1. The sealing strip 4 seals the gap between the baffle plate 3 and the mounting frame 1.
[0030] To further reduce the wear on the sealing strip 4 when the gate plate 2 moves up and down, the gate plate 2 is provided with a pusher for pushing the baffle plate 3. A support strip 9 is solidly provided on the baffle plate 3 along the movement trajectory of the pusher. The bottom of the support strip 9 has a slot 10 for the pusher to be inserted and matched. When the gate plate 2 moves upward and the top part abuts against the outer wall of the support strip 9, it drives the baffle plate 3 away from the gate plate 2, so that there is a certain gap between the sealing strip 4 and the gate plate 2. When the pusher is inserted into the slot 10, the baffle plate 3 is pressed closer to the gate plate 2 by the water pressure, and the sealing strip 4 abuts against the gap between the gate plate 2 and the mounting bracket 1 to seal.
[0031] The first embodiment of the actuating member, such as Figure 1 , 3 and Figure 5 As shown, the actuating member is a top block 8, and the top of the top block 8 is inclined.
[0032] The second embodiment of the actuating member, as follows: Figure 2 , 4 and Figure 6 As shown, the actuating component is a top shaft 11, which is a horizontally arranged shaft.
[0033] A limiting block 12 is fixedly installed at the top of the support bar 9 to limit the movement of the jacking member.
[0034] In summary, this type of flood control gate for reservoirs, equipped with an interception structure, operates by lowering the gate plate 2 into position so that water contacts its upstream surface. As the water level rises, water pressure acts on the movable baffle plate 3, pushing it towards the mounting frame 1. At this time, the sealing strip 4 on the baffle plate 3 tightly adheres to the gap between the baffle plate 3 and the mounting frame 1, forming an effective seal and preventing water leakage.
[0035] When the gate plate 2 moves up and down, the top part abuts against the outer wall of the support strip 9, driving the baffle plate 3 away from the gate plate 2 so that there is a certain gap between the sealing strip 4 and the gate plate 2, reducing the wear on the sealing strip 4. Only when the gate plate 2 moves into position, the pushing part is inserted into the slot 10. At this time, the baffle plate 3 is pressured by water and moves closer to the gate plate 2, and the sealing strip 4 abuts against the gap between the gate plate 2 and the mounting bracket 1 to seal.
[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
