Description

Technical Field

[0001] The utility model relates to the technical field of river channel water blocking devices, in particular to a river channel water blocking device. Background Art

[0002] The water blocking device in a river channel can control the flow and stillness of water in the river channel. After searching, the patent with Chinese patent authorization number CN219045134U discloses a water blocking device in a river channel, which relates to the technical field of water conservancy engineering, including a fixing mechanism, an adjusting mechanism, and a water baffle. The number of the fixing mechanisms is two, and the two fixing mechanisms have the same structure. A plug rod is fixedly installed on the lower surface of the water baffle, and a connecting frame is fixedly installed on the opposite sides of the water baffle. A telescopic rod is fixedly installed on the upper surface of the connecting frame, and the telescopic rod is connected to the adjusting mechanism. The beneficial effects of the utility model are as follows: the worm is driven to rotate by a motor, and the worm can be driven to rotate because the worm is meshed with the worm wheel. Since the worm wheel and the gear are fixedly sleeved on the surface of the rotating shaft, the worm wheel can drive the gear to rotate through the rotating shaft. By using the cooperation of the gear and the rack, the movable rod can be inserted into the ground to fix the fixing mechanism, and at the same time drive the adjusting mechanism and the water baffle to move, so that the water baffle enters underwater, and there is no need for the operator to manually place it in the water, thereby avoiding the situation where the operator falls into the water. However, when the device is in use, a rod is inserted into the bottom soil of the river channel. Long-term extraction and insertion will soften the soil at the bottom, resulting in a subsequent decrease in soil height, causing the water to continue to flow out after the baffle plate is lowered. At the same time, the water baffle is supported by the connecting frame, and the water baffle is subjected to the pressure of the water flow for a long time, which will cause this pressure to exert pressure on the connecting frame through the water baffle. Long-term support will cause the connecting frame to bend and deform, causing damage to the device. Utility Model Content

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example 1

[0018] See also Figure 1-4 The embodiment of the utility model provides a river water blocking device, including a mounting frame 1 and a base 3. The mounting frame 1 is U-shaped, the base 3 is fixedly installed inside the river channel, and is arranged between the mounting frames 1, and a water baffle 5 is slidably connected between the mounting frames 1. The front end side wall of the water baffle 5 is fastened with a triangular cone block 6 through a fixing bolt, a first sealing tooth 4 is fixedly installed on the top surface of the base 3, and a second sealing tooth 11 is fixedly installed on the ground of the water baffle 5. The first sealing tooth 4 is sealed and connected to the second sealing tooth 11. The front end of the base 3 is wedge-shaped. When the water baffle 5 is separated from the base 3, water flows between the water baffle 5 and the base 3. Since the front end of the base 1 is wedge-shaped and the front end of the water baffle 5 is installed with a triangular cone block 6, when the water flows or stands still, the pressure and impact of the water flow on the device as a whole can be reduced.

[0019] Example 2

[0020] In this embodiment, Figure 1-4 As shown,

[0021] Both ends of the mounting frame 1 are respectively installed in pits on both sides of the river channel, and casting columns 2 are cast in the pits, and the casting columns 2 are fitted with the side walls of the mounting frame 1. When installing the mounting frame 1, pits are dug in both sides of the river channel, and the supporting columns at both ends of the mounting frame 1 are respectively placed in the pits, and hydraulic cement is cast in the pits to form casting columns. The supporting strength of the supporting columns on both sides of the mounting frame 1 is strengthened, and baffles 10 are symmetrically fixedly installed on both side walls of the mounting frame 1. The total distance between two adjacent baffles is greater than the diameter of the pit, and the side of the pit is open, and the opening direction corresponds to the inside of the river channel.

[0022] Example 3

[0023] In this embodiment, Figure 1-4 As shown, movable grooves 8 are provided inside the side walls of both sides of the mounting frame 1, and the inside of the movable grooves 8 is rotatably connected with a screw rod 12, and a reciprocating motor 7 is symmetrically fixedly installed on the top surface of the mounting frame 1. The output ends of the reciprocating motor 7 pass through the inside of the top side walls of the mounting frame 1 and are fixedly connected to the top of the screw rod 12. Moving blocks 9 are symmetrically fixedly installed on the side walls of both sides of the water retaining plate 5, and the moving blocks 9 are threadedly sleeved on the rod wall of the screw rod 12. When water is injected, the reciprocating motor 7 is turned on to rotate the screw rod 12, which can move the water retaining plate 5 downward, so that the first sealing teeth 4 are meshed and connected with the second sealing teeth 11, so as to block water in the river channel. Conversely, the reciprocating motor 7 can be used to move the water retaining plate 5 upward.

[0024] It should be noted that in this embodiment, when the river water blocking device is used, Figure 1-4 As shown, when installing the mounting frame 1, pits are dug on both sides of the river channel, and the support columns at both ends of the mounting frame 1 are placed in the pits respectively, and water is poured in the pits to form cast columns, and the support columns on both sides of the mounting frame 1 are strengthened. When the water baffle 5 is separated from the base 3, water flows through the water baffle 5 and the base 3. Since the front end of the base 1 is wedge-shaped and a triangular cone block 6 is installed at the front end of the water baffle 5, when the water flows or stands still, the pressure and impact force of the water flow on the device as a whole can be reduced. When the water is blocked, the reciprocating motor 7 is turned on to rotate the screw 12, so that the water baffle 5 can move downward, and the first sealing tooth 4 is meshed and connected with the second sealing tooth 11, so as to block water in the river channel. Conversely, the reciprocating motor 7 can be used to move the water baffle 5 upward.
