Technical Field

[0001] The utility model relates to the field of water retaining equipment for lock channels, and particularly relates to a water retaining guide vane device. Background Art

[0002] A lock is the most widely used waterway navigation building. By opening and closing the filling and discharging gates, the water level in the lock chamber is regulated to realize the stepped lifting of the ships in the lock chamber, and the navigation difficulties caused by the water level drop of the waterway can be overcome. Generally, the lock is set as an upstream lock and a downstream lock, and a flow channel is arranged between the upstream lock and the downstream lock for water regulation or flood discharge between the locks.

[0003] Generally, a power generation device is arranged at the tail end of the flow channel to generate electricity by using the kinetic energy and potential energy of the water in the flow channel. In order to adjust the water flow velocity flowing into the power generation device to protect the generator, or to temporarily close the power generation device during maintenance, a temporary water retaining device needs to be arranged upstream of the power generation device. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a water retaining guide vane device, which is beneficial to adjusting or temporarily closing the water flow flowing into the power generation device in the flow channel, protecting the generator and facilitating maintenance.

[0005] To solve the above technical problem, the technical scheme adopted by the utility model is: a water retaining guide vane device, including a guide vane frame arranged at the tail of the flow channel. The flow channel includes a plurality of branch flow channels, and the tails of the branch flow channels converge to form a confluent flow channel. The guide vane frame is arranged in the confluent flow channel, and the guide vane frame is arranged upstream of the power generation device. A guide vane mechanism is arranged on the guide vane frame. The guide vane mechanism includes a plurality of guide vane shafts arranged in the guide vane frame. Guide vane blades are arranged on the guide vane shafts, and the guide vane shafts are driven by a driving mechanism.

[0006] In a preferred scheme, the branch flow channels include a left flow channel, a middle flow channel and a right flow channel, and guide vane mechanisms are arranged on the guide vane frame corresponding to the left flow channel, the middle flow channel and the right flow channel.

[0007] In a preferred scheme, the driving mechanism includes a guide vane motor arranged on the guide vane frame. The guide vane motor is connected to one of the guide vane shafts. Adjacent groups of guide vane blades are connected by a connecting rod pulling mechanism. The connecting rod pulling mechanism includes a pull rod and connecting rods hinged at both ends of the pull rod. The ends of the two connecting rods away from the pull rod are respectively hinged and installed at the ends of two groups of guide vane blades. When the guide vane blades rotate to be parallel to the water flow direction, the two connecting rods of each connecting rod pulling mechanism are respectively hinged to the downstream end and the upstream end of adjacent two groups of guide vane blades.

[0008] In a preferred scheme, the guide vane frame is an arc-shaped structure arched upstream.

[0009] In a preferred embodiment, when the guide vane blades rotate to be perpendicular to the water flow direction, the edges of adjacent guide vane blades overlap and are distributed.

[0010] The water retaining guide vane device provided by the utility model has the following beneficial effects:

[0011] 1. Driven by the driving mechanism, when the guide vane blades rotate to the horizontal state and are perpendicular to the water flow direction, it is in a water blocking state. When the guide vane blades rotate to be parallel to the water flow direction, it is in a water passing state. Thus, the opening or closing of the water flow in the flow channel is realized, and the temporary closing during the maintenance of the power generation device is realized.

[0012] 2. By adjusting the angle between the guide vane blades and the water flow direction, the adjustment of the opening degree is realized, which is beneficial to adjusting the size of the water flow flowing into the power generation device in the flow channel.

[0013] 3. Guide vane mechanisms are provided on the guide vane frame corresponding to the left flow channel, the middle flow channel and the right flow channel respectively. It is convenient for the overall control of the water flow in the flow channel. As long as more than one guide vane mechanism corresponding to the three branch flow channels is opened, the normal power generation of the power generation device can be ensured, and it will not affect the separate scheduling and use of the water flow in the branch flow channel corresponding to the closed guide vane mechanism.

[0014] 4. The provided connecting rod pulling mechanism realizes the simultaneous opening and closing of all guide vane blades in each group of guide vane mechanisms. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0021] The technical solution of the present utility model will be further described below in conjunction with the accompanying drawings.

[0022] As Figures 1 to 4 shown, a water retaining guide vane device includes a guide vane frame 2 arranged at the tail of the flow channel 1. The guide vane frame 2 is arranged along the entire flow channel 1 as a whole, and the guide vane frame 2 is arranged upstream of the power generation device 3.

[0023] The flow channel 1 includes a plurality of branch flow channels, and the tails of the branch flow channels converge to form a confluence flow channel 104. The guide vane frame 2 is arranged in the confluence flow channel 104. A guide vane mechanism 4 is arranged on the guide vane frame 2. The guide vane mechanism 4 includes a number of guide vane shafts 401 arranged in the guide vane frame 2. The guide vane shafts 401 are rotatably installed in the guide vane frame 2 through bearings. Guide vane blades 402 are arranged on the guide vane shafts 401, and the guide vane shafts 401 are driven by a driving mechanism 5.

[0024] Driven by the driving mechanism 5, when the guide vane blades 402 rotate to a horizontal state and are perpendicular to the water flow direction, it is in a water blocking state. At this time, the edges of adjacent guide vane blades 402 are overlapped and distributed to improve the water blocking effect. When the guide vane blades 402 rotate to be parallel to the water flow direction, it is in a water passing state.

[0025] Preferably, the branch flow channels include a left flow channel 101, a middle flow channel 102, and a right flow channel 103. Guide vane mechanisms 4 are arranged on the guide vane frame 2 corresponding to the left flow channel 101, the middle flow channel 102, and the right flow channel 103. It is convenient for the overall control of the water flow in the flow channel 1. As long as more than one of the guide vane mechanisms 4 corresponding to the 3 branch flow channels are opened, the normal power generation of the power generation device can be ensured, and it will not affect the separate scheduling and use of the water flow in the branch flow channels corresponding to the closed guide vane mechanisms 4.

[0026] The driving mechanism 5 can be a driving motor, but in order to realize the simultaneous rotation of the guide vane blades 402 of each group of guide vane mechanisms 4, in this embodiment, as Figures 3 to 4As shown in the figure, the driving mechanism 5 includes a guide vane motor 501 provided on the guide vane frame 2. The guide vane motor 501 is connected to one of the guide vane shafts 401. Adjacent two groups of guide vane blades 402 are connected by a connecting rod pulling mechanism. The connecting rod pulling mechanism includes a pull rod 502 and connecting rods 503 hinged at both ends of the pull rod 502. The ends of the two groups of connecting rods 503 away from the pull rod 502 are respectively hinged and installed at the ends of the two groups of guide vane blades 402. When the guide vane blades 402 rotate to be parallel to the water flow direction, the two connecting rods 503 of each connecting rod pulling mechanism are respectively hinged to the downstream end and the upstream end of the adjacent two groups of guide vane blades 402.

[0027] Driving one group of guide vane shafts 410 to rotate by the guide vane motor 501 can drive through the connecting rod pulling mechanism to form the effect that all the guide vane blades 402 open and close simultaneously.

[0028] Preferably, as Figure 1 shown in the figure, the guide vane frame 2 is an arc-shaped structure arched upstream. On the one hand, when closing to face the water flow impact, a higher strength can be formed with a lighter structure. On the other hand, when the guide vane mechanism 4 is in the closed state, water can be guided to both sides through the arc gate, which is convenient for entering the power generation water channels communicating with the left water channel 101 or the right water channel 103 to maximize the utilization of water kinetic energy.

[0029] The above embodiments are only the preferred technical solutions of the present invention and should not be regarded as limitations to the present invention. The protection scope of the present invention should be the technical solutions recorded in the claims, including the equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. That is, the equivalent replacement improvements within this range are also within the protection scope of the present invention.
