[0015] [Explanation of Key Component Symbols] 1: Gate opening 2: Installation Platform 3: Flat panel gate 31: Guide wheel 4: Gate slot 5: Fixed guide rail 6: Movable guide rail Detailed Implementation

[0016] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended purpose of the invention, the following detailed description of the specific implementation method, structure, features and effects of the movable flat gate device proposed according to this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0017] Please see Figure 1 and Figure 2This is a schematic diagram of the various parts of the movable flat gate device of this utility model. The movable flat gate device includes a gate opening 1 and a mounting platform 2 disposed above the gate opening 1. The mounting platform is also provided with a gate slot 4 for the flat gate 3 to pass through. A gate track slot 11 is provided on each side of the gate opening 1. The gate track slot 11 is used to cooperate with the guide wheels 31 on both sides of the flat gate 3 to guide and limit the vertical movement of the flat gate.

[0018] Two guide wheels 31 are respectively provided on both sides of the flat gate 3. The guide wheels 31 are distributed at intervals along the vertical direction on the side of the flat gate 3, and the guide wheels 31 are located in the lower middle part of the flat gate 3. The rotation axis of the guide wheels 3 is perpendicular to the side of the flat gate 3, and the radial surface of the guide wheels 31 is parallel to the side of the flat gate 3 where the guide wheels are located. The radial dimension of the guide wheels 31 is greater than the thickness of the flat gate 3, so that when the guide wheels 31 are guided and engaged with the gate track groove 11, the radial direction of the guide wheels 31 is limited by the gate track groove 11. This restricts the movement of the flat gate 3 parallel to the water flow direction, effectively preventing the front and rear end faces (the upstream face and the downstream face) of the flat gate 3 from colliding with the gate groove 4 and being damaged.

[0019] In this embodiment of the utility model, the gate track groove 11 is located in the middle of the gate groove 4 in the direction parallel to the water flow, but it is not limited to this.

[0020] The flat gate 3 is also detachably equipped with a roller device on each side. This roller device includes two rollers 32 symmetrically positioned relative to the guide wheels 31 below the flat gate 3, and a support frame for connecting the rollers 32 to the flat gate 3. The lower end face of the rollers 32 is flush with the lower end face of the guide wheels 31 at the lower end of the flat gate 3, allowing them to be supported on the same plane. This invention, by providing roller devices on both sides of the flat gate 3, ensures that the flat gate 3 is supported by the guide wheels 31 on both sides when the gate slot 4 is moved out, and the rollers 32 on both sides of the guide wheels 31 ensure the stability of the flat gate and prevent it from tipping over.

[0021] The support frame includes a horizontally arranged connecting plate 33 and connecting rods 34 that connect the rollers 32 to the connecting plate 33. Both connecting rods 34 are fixed below the connecting plate 33 and are arranged in an inverted V-shape. A reinforcing plate 35 is provided between the two connecting rods 34 to enhance their supporting stability. Preferably, the reinforcing plate 35 is arranged parallel to the connecting plate 33 and located inside the inverted V-shaped structure. Flanges 36 are also fixed on both sides of the flat gate 3 for quick and detachable connection with the connecting plate 33 of the support frame.

[0022] In this embodiment, the connecting plate 33 is a steel plate, the connecting rod 34 is made of I-beams, and the reinforcing plate 35 is made of square steel. The roller 32 is made of high-strength material, capable of withstanding the vertical load of the gate and moving flexibly to meet the displacement requirements during gate opening and closing.

[0023] The mounting platforms 2 on both sides of the gate opening 1 are also equipped with rails. The guide wheels 31 and rollers 32 on both sides of the flat gate 3 are supported on the guide rails and can move along the guide rails, thereby realizing the movement requirements of the flat gate. When the guide wheels 31 and rollers 32 on both sides of the flat gate 3 are supported on the guide rails, the lower end face of the flat gate 3 is higher than the mounting platform 2. That is, the distance between the lower end face of the flat gate 3 and the guide wheels 31 below it is less than the height of the guide rail, so that the flat gate 3 can be supported on the guide rails by the guide wheels 31 and rollers 32 and move along the guide rails.

[0024] The guide rails include a fixed guide rail 5 and a movable guide rail 6. The movable guide rail 6 is positioned directly above the gate track groove 11 when the flat gate 3 is lifted, allowing the guide wheels and rollers on both sides of the flat gate 3 to be supported on the movable guide rail 6 when it falls. The movable guide rail 6 can be removed after use to prevent it from obstructing the gate track groove 11 and affecting the normal operation of the device. The mounting platform 2 is also fixedly equipped with a fixed guide rail 5 connected to the movable guide rail 6, allowing the flat gate 3 to be moved to a designated position via the fixed guide rail 5. Preferably, a stop protrusion is fixedly provided at the end of the fixed guide rail 5 away from the movable guide rail 6, which stops and limits the rollers 32, preventing the flat gate 3 from detaching from the guide rail due to excessive movement. Preferably, both the fixed guide rail 5 and the movable guide rail 6 are composed of I-beams.

[0025] When the flat gate of this utility model needs to be moved to the installation platform, first lift the flat gate 3 above the gate opening, then lay the movable guide rail above the gate track groove 11 and connect it with the fixed guide rail 5, then install the roller device, and slowly lower the flat gate onto the guide rail, finally pushing the flat gate to the installation platform for fixation. When other operations need to be performed at the opening, such as placing algae-blocking nets, the movable guide rail that obstructs the operation can be moved away.

[0026] When maintaining a flat gate, the operating steps are the reverse of those described above: First, re-lay the movable guide rail, push the flat gate in the opposite direction to above the orifice, lift the flat gate upwards, and after the flat gate is disengaged from the guide rail, remove the movable guide rail and roller assembly. Finally, lower the flat gate to allow it to work normally. Throughout the entire process, attention must be paid to safety during operation to ensure smooth raising, lowering, and movement of the gate, avoiding collisions that could damage the equipment.

[0027] This utility model guide rail consists of a fixed end and a movable end, which complement each other. The fixed end serves as the basic support unit of the guide rail system, fixing the gate in place when other operations are being carried out at the gate opening. The movable end, designed with "dynamic adaptation" as its core principle, aims to ensure operational flexibility during normal gate operation. When the working gate needs to be opened or closed, the movable end can be quickly disassembled via a quick-release structure, avoiding mechanical interference with the gate's movement trajectory. This modular design significantly shortens the operation switching time; actual testing shows that a single disassembly process can be completed by two people within 3 minutes. The fixed end and movable end complement each other through the complementary logic of "rigid support + flexible switching," constructing a complete guide rail functional system. The "anchoring characteristics" of the fixed end and the "rapid response" of the movable end create a seamless connection in operational scenarios: during non-operational periods, the fixed end ensures operational safety, while during operation, the detachable design of the movable end releases the gate's movement space, achieving the dual goals of "maintenance stability" and "operational efficiency."

[0028] This utility model's roller device utilizes high-strength steel to construct the support frame. A triangular stabilizing structure evenly distributes the gate's lateral overturning load to the main gate frame. When the gate moves horizontally, the guide wheels positioned on the side bear the lateral load through a double row of rollers, effectively preventing lateral instability. During normal gate operation, the guide wheels roll precisely along the gate's track groove, eliminating the gate's "track-biting" phenomenon. By replacing traditional manual handling with the rolling friction between the guide rail and the rollers, the movement of a 1.5-ton gate requires only 2-3 people working with a small drive unit, reducing manpower requirements by 60%-80% and significantly lowering operational risks.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
