[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figures 1-6 As shown, a temporary blocking device for a canal is provided, comprising a fixing frame 1, a main baffle 2 being fixed on one side of the fixing frame 1, the fixing frame 1 being made of metal and being able to support and fix the main baffle 2, a limiting device 6 for fixing the blocking device in the canal being fixed on the middle and lower end of the other side of the fixing frame 1, a fixing device 5 for fixing the blocking device on the canal being fixed on the upper end of the side of the fixing frame 1 away from the main baffle 2, a drain pipe 3 being fixed on the middle part of the main baffle 2, a connecting flange 4 being fixed on the end part of the drain pipe 3, for facilitating the connection of the drainage pipe to discharge the canal water, two auxiliary baffles 7 matching the edge of the canal being movably inserted on both sides of the fixing frame 1, the auxiliary baffle 7 being inserted between the main baffle 2 and the limiting device 6, for cooperating with the main baffle 2 to block the canal, a flexible sealing edge 71 for improving the sealing effect being fixed on the edge of the auxiliary baffle 7, the flexible sealing edge 71 being made of soft rubber or silicone and for improving the sealing effect.

[0023] In this embodiment, the limiting device 6 includes at least two second fixed sleeves 61 fixed in parallel on the side walls of the fixed frame 1, and a telescopic stop arm 62 is slidably installed at each end of the second fixed sleeve 61. The end of the telescopic stop arm 62 away from the second fixed sleeve 61 is fixed with an anti-slip rubber sleeve 64, and the side walls at both ends of the second fixed sleeve 61 are threadedly installed with hand screws 63 that limit the position of the telescopic stop arm 62. The elongation of the telescopic stop arm 62 can be adjusted by the hand screws 63. When in use, the end of the telescopic stop arm 62 equipped with the anti-slip rubber sleeve 64 can be rested on the inner wall of the canal, relying on friction to provide support to prevent the device from moving.

[0024] In this embodiment, the fixing device 5 includes a first fixing sleeve 51 horizontally fixed on the upper side wall of the fixing frame 1, and a fixing arm 52 is slidably installed at each end of the first fixing sleeve 51. A guide sleeve 53 is fixed at one end of the fixing arm 52 away from the first fixing sleeve 51, and the guide sleeve 53 is nested on the fixing seat 54. The fixing seat 54 is fixed to both sides of the canal by using a counterweight or a ground nail. The fixing frame 1 and the fixing seat 54 can be connected as a whole through the fixing arm 52 to prevent them from rotating and moving, thereby facilitating rapid position fixation.

[0025] In this embodiment, the fixing seat 54 includes a base plate 541 , on which a vertically arranged column 542 is fixed. The column 542 is installed in conjunction with the guide sleeve 53 . The base plate 541 may adopt a frame structure to reduce weight.

[0026] In this embodiment, a handle groove 72 is formed on the upper end of the auxiliary baffle 7 to facilitate the installation and removal of the auxiliary baffle 7 by holding it.

[0027] In this embodiment, a water storage frame 8 is fixed to one side of the lower end of the fixing frame 1. When the sealing device is lowered, the water stored in the water storage frame 8 can increase the weight of the device itself, which makes it easier to sink into the canal quickly and increase friction, thereby improving stability after fixation.

[0028] The working principle of the present invention is as follows: when the canal needs to be temporarily blocked, the two fixing seats 54 are fixed on both sides of the canal to prevent loosening, and then the fixing frame 1 with the main baffle 2 is placed in the canal to ensure that the main baffle 2 faces the side where water flows in. When water enters the water storage frame 8, the main baffle 2 can be accelerated to sink into the canal and increase its own weight. In the process of fixing the frame 1 below, the fixing arm 52 is pulled out so that the guide sleeve 53 corresponds to the position of the bottom plate 541, and the fixing seat 54 is used to complete the preliminary fixation of the main baffle 2 to prevent it from moving with the water flow. Then, the position of the limit device 6 is adjusted so that one end of the telescopic baffle arm 62 equipped with the anti-slip rubber sleeve 64 is against the side wall of the canal, and it is tightened with the hand screw 63 to prevent loosening, and then the auxiliary baffle 7 is inserted from top to bottom between the main baffle 2 and the limit device 6. When the water level in the canal rises, the water can be guided to be discharged through the drain pipe 3 and the drainage pipe. At this time, the maintenance work of the canal can be carried out near the blocking device. After the construction is completed, the auxiliary baffles 7 are pulled out in turn, and then the limiting device 6 is loosened and the device is taken out. When the working area is relatively flat, the canal water is easy to flow back. A blocking device can be installed on each side of the working area to prevent the canal water from flowing back and realize the closed operation of the working area.
