Technical Field

[0001] The utility model relates to the field of water conservancy project construction, in particular to a water flow guiding device used in water conservancy project construction. Background Art

[0002] During the construction of water conservancy projects, since the humid construction environment is not conducive to construction, it is usually necessary to guide and discharge the water flow in the river first to provide a dry construction environment.

[0003] The utility model patent with patent publication number CN216006810U discloses a water flow guiding and regulating device for water conservancy and hydropower construction. It can guide the water flow to a specified direction and position by setting a guiding control frame, an opening and closing control device, a conveying pipe, a conveying trough and an input pipe. However, it can only drain water in a fixed direction and cannot change the water flow direction according to actual conditions.

[0004] Therefore, we need to design and develop a water flow guide device for water conservancy project construction that can change the direction of water flow according to actual needs. Utility Model Content

[0010] Preferably, the valve block is cylindrical, and two through holes are formed on the outer side of the valve block.

[0011] Preferably, the outer shell of the shunt tube is detachable for easy collection and use.

[0012] The beneficial effects of the utility model are as follows: 1. The utility model can change the direction and position of water flow by rotating the handle to drive the valve block to rotate and controlling the direction of the through hole of the valve block.

DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods. Example 1

[0022] A water flow guiding device for water conservancy project construction, such as Figure 1-Figure 3As shown, it includes a diverter pipe 1, a reversing mechanism 4, a valve block 41, a link block 42 and a handle 43. The diverter pipe 1 is provided with a reversing mechanism 4 on the top, and the reversing mechanism 4 can be used to control the flow direction of water. The diverter pipe 1 is rotatably connected with the valve block 41 inside, and the upper part of the valve block 41 is fixedly connected with the handle 43, and the upper part of the handle 43 is fixedly connected with the link block 42. Two through holes are provided on the outer side of the valve block 41, which can be used to control the precise steering of the water flow.

[0023] During the construction of water conservancy projects, people often need to guide the direction of water flow. The existing conveying and guiding devices used in water conservancy and hydropower construction can only guide the water flow to a fixed direction and position during use, but cannot change the water flow direction in time according to the actual construction situation. Therefore, people can use this equipment to reverse the water flow. First, the device can be placed in a river channel where a water conservancy project is being constructed, and the water will flow from the front to the rear of the diversion pipe 1. When the direction of the water flow needs to be changed, people can turn the handle 43. When the handle 43 rotates clockwise, it drives the valve block 41 to rotate clockwise. When one through hole of the valve block 41 is rotated to connect with the inside of the left diversion pipe 1, and the other through hole matches the direction of water flow entry, the water will flow out of the left diversion pipe 1. When the handle 43 rotates counterclockwise, it drives the valve block 41 to rotate counterclockwise, so that the through hole of the valve block 41 is connected with the internal opening of the right diversion pipe 1, and the water will flow out of the right diversion pipe 1. Therefore, the direction of rotation of the valve block 41 can be changed to control the direction of the water flow and guide it. When the direction of the water flow is changed, stop rotating the handle 43. Example 2

[0024] On the basis of Example 1, Figure 4-Figure 5 As shown, it also includes a control mechanism 5, which includes a pressure handle 51, a baffle 52, a pin 53, an elastic component 54, a limit frame 55 and a limit block 56. The left and right sides of the shunt pipe 1 are symmetrically connected to the limit frames 55, and the upper parts of the limit frames 55 on the left and right sides are slidably connected to the baffles 52. The baffles 52 are normally located at the upper part of the shunt pipe 1, and the upper parts of the baffles 52 are fixedly connected to the pressure handle 51. There are four elastic components 54, and two elastic components 54 are connected between the baffles 52 on the same side and the limit frames 55 on the same side. The two elastic components 54 on the same side are symmetrically arranged, and the middle parts of the limit frames 55 on the left and right sides are fixedly connected to the limit blocks 56, and the limit blocks 56 are provided with a plurality of through holes. The limit blocks 56 are connected to the pins 53, and the pins 53 can be used to prevent the blocks from moving downward excessively.

[0025] When it is necessary to control the flow of water, under normal conditions, the elastic component 54 is stretched, and the pin 53 is inserted into the through hole on the limit block 56, which is located below the baffle 52, thereby preventing the baffle 52 from moving downward. When it is necessary to reduce the water flow, people can pull out the pin 53, and the elastic component 54 is compressed and reset, driving the baffle 52 to move downward. When the baffle 52 moves to a suitable position, people can insert the pin 53 into the through hole on the limit block 56 to prevent the baffle 52 from moving further downward. In this way, the water flow will become smaller. In this way, the water flow can be controlled by moving the baffle 52 up and down.

[0026] like Figure 2 As shown, a filter screen 2 for purification and filtration is also included, and the filter screen is connected to the front side of the inner part of the diverter pipe 1.

[0027] When water flows through the filter screen 2 , larger sediment in the river channel can be blocked outside the diversion pipe 1 , so that the amount of sediment in the water flow entering the device is reduced, and the diversion pipe 1 is prevented from being blocked.

[0028] like Figure 2 As shown, it also includes a turbine 3 for accelerating the flow rate of water. There are two turbines 3, and the middle part of the diverter pipe 1 is rotatably connected to the turbine 3.

[0029] When water flows in from the front of the diverter pipe 1 and flows through the turbine 3 , the rotation of the turbine 3 can speed up the flow of the water.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
