DETAILED DESCRIPTION

[0021] In order to better understand the utility model, the content of the utility model is further clearly set forth below in conjunction with examples, but the protection content of the utility model is not limited to the following examples only. In the following description, a large number of specific details are given in order to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details.

[0022] As Figure 1 shown, a water conservancy gate opening and closing device, including base 101, base 101 is provided with the mounting frame 102 of U type, the gate sealing sliding is arranged between the both sides of mounting frame 102, the both sides of the upper end of gate are further provided with extension plate 103, the top of mounting frame 102 is further provided with telescopic push rod 104 vertically, telescopic push rod 104 is hydraulic telescopic rod, the lower end of the output shaft of telescopic push rod 104 is provided with the support plate 105 for the auxiliary support of extension plate 103. The telescopic push rod 104 of both sides does not necessarily run synchronously, because the support plate 105 does not necessarily realize or release the auxiliary support of extension plate 103.

[0023] The top of mounting frame 102 is further provided with electric winch 201, the output shaft of electric winch 201 is provided with pull rope 202, the lower end of pull rope 202 is connected with the top of gate.

[0024] In the initial state, the gate is in the closed state, and is tightly sealed between the both sides of mounting frame 102 and the top of base 101. At this time, the output shaft of telescopic push rod 104 is in the elongated state, and the support plate 105 is located below the extension plate 103; the pull rope 202 of electric winch 201 remains relaxed, and does not exert upward tension on the gate.

[0025] When the gate needs to be opened, the electric winch 201 is first started, the electric winch 201 exerts an upward pulling force on the gate through the pulling rope 202, so that the gate slides upward along the connecting sliding grooves 108 on both sides of the mounting frame 102 by a certain distance, thereby being opened by a corresponding degree.

[0026] Then, the output shaft of the telescopic push rod 104 is driven to shorten by a certain length upward, the output shaft drives the supporting plate 105 to move upward until the supporting plate 105 contacts the extension plate 103 on the top of the gate, thereby providing auxiliary support for the gate, ensuring that the gate remains stable after being opened by any degree, and avoiding damage to the electric winch 201 and the pulling rope 202 due to continuous pulling force.

[0027] When the gate needs to be closed, the output shaft of the telescopic push rod 104 is first driven to lengthen by a certain length downward, the supporting plate 105 is driven to separate from the extension plate 103 and reset downward, and then the operation of the electric winch 201 is stopped and the pulling rope 202 is untightened. At this time, the gate slides downward along the connecting sliding grooves 108 under the action of its own gravity, and returns to the initial closed position.

[0028] According to another embodiment of the utility model, as shown in Figure 1 , a guide insertion cylinder 106 is further arranged on the top of the mounting frame 102 at the side end of the telescopic push rod 104, and a guide insertion rod 107 is fixedly connected to the supporting plate 105 and inserted into the guide insertion cylinder 106. Through the insertion and cooperation of the guide insertion cylinder 106 and the guide insertion rod 107, the supporting plate 105 can be stably vertically moved, and the telescopic push rod 104 can be prevented from being easily deformed and damaged.

[0029] According to another embodiment of the utility model, as shown in Figure 1 , 2 , a fixed ring 203 is fixedly connected to the top of the gate, and the lower end of the pulling rope 202 is tied and fixed to the fixed ring 203. By connecting the pulling rope 202 with the fixed ring 203, the flexible fixing of the pulling rope 202 and the gate can be realized.

[0030] According to another embodiment of the utility model, as shown in Figure 4 , connecting sliding grooves 108 are further fixedly connected to the side ends of the mounting frame 102, and connecting sliding blocks 109 are further fixedly connected to the gate and slidably connected to the connecting sliding grooves 108. Through the sliding connection of the connecting sliding grooves 108 and the connecting sliding blocks 109, the mounting frame 102 and the gate can be stably and slidably connected, and the sealing and sliding connection of the gate and the mounting frame 102 can be avoided from being affected by the inclination of the gate.

[0031] According to another embodiment of the utility model, as shown in Figure 2 , 3As shown, the top of the support plate 105 is further fixed with a clamping protrusion 204, and the bottom of the extension plate 103 is further provided with a clamping groove 205 clamped with the clamping protrusion 204. When the extension plate 103 is assisted and supported by the support plate 105, the clamping protrusion 204 and the clamping groove 205 can be clamped and matched, so that the support plate 105 can more stably support the extension plate 103 and the gate.

[0032] According to another embodiment of the present application, a reinforcing plate is further fixed between the extension plate 103 and the gate, and two ends of the reinforcing plate are respectively welded with the extension plate 103 and the gate. The reinforcing plate can enhance the connection firmness between the gate and the extension plate 103.

[0033] The above is the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should be considered as the protection scope of the present application.
