Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy engineering, and in particular relates to a water conservancy generator set. Background Art

[0002] A hydroelectric generator set is also called a "water turbine generator set". Each turbine in a hydropower station is combined with a matching generator to form a power generation unit. It is the main power equipment for the hydropower station to produce electricity. When the water flow used by the hydropower station passes through the turbine, the water energy is converted into mechanical energy that drives the machinery to rotate; the generator then converts the mechanical energy into electrical energy and outputs it.

[0003] Although there are many kinds of hydroelectric generators at present, there are still some problems. For example, in the current hydroelectric generators, water flow is needed to drive the water wheel to rotate, and then drive other equipment to achieve power generation. When the water wheel is linked in the water, its blades always face the side of the water flow. When rotating, the blades on the side facing away from the water flow slide in the water, and there is a huge water resistance, which leads to the waste of water energy and the inability to achieve efficient power generation.

[0007] The linkage power generation assembly includes a transmission frame and a linkage unit, the transmission frame is rotatably connected to the support rod, and the limit rod is located inside the transmission frame, and the linkage unit is arranged on one side of the transmission frame;

The linkage rod is rotatably connected to the transmission frame, the water-blocking blade is arranged on the linkage rod, one end of the docking plate is fixed on the linkage rod close to one end of the transmission frame, and the limit unit is arranged on the other end of the docking plate.

[0012] The transmission rod is fixed at one end of the transmission frame and is rotatably sleeved outside the support rod. The driving gear is coaxially fixed on the transmission rod. The driven gear is rotatably connected in the gear protection box and meshes with the driving gear.

[0013] Preferably, the abutment rod is composed of two round rods, one of which is slidably connected in the inner cavity of the other round rod, and a spring is arranged between the two round rods.

The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0024] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0025] The utility model embodiment provides a water conservancy generator set equipment, such as Figure 1-5 As shown, it includes: a support rod 1, a limit rod 2, a gear protection box 3, a linkage power generation component 4 and a transmission component 5;

[0026] The support rod 1 is fixed on the external support structure, the limit rod 2 is coaxially fixed on the support rod 1, the gear protection box 3 is arranged at one end of the support rod 1, the linkage power generation component 4 is connected to the support rod 1, and the transmission component 5 is arranged between the linkage power generation component 4 and the limit rod 2;

[0027] The linkage power generation assembly 4 includes a transmission frame 41 and a linkage unit. The transmission frame 41 is rotatably connected to the support rod 1, and the limit rod 2 is located inside the transmission frame 41. The linkage unit is arranged on one side of the transmission frame 41.

[0028] The transmission assembly 5 includes a linkage rod 51, a water-blocking blade 52, a docking plate 53 and a limiting unit. The linkage rod 51 is rotatably connected to the transmission frame 41, the water-blocking blade 52 is arranged on the linkage rod 51, one end of the docking plate 53 is fixed to one end of the linkage rod 51 close to the transmission frame 41, and the limiting unit is arranged at the other end of the docking plate 53.

[0029] It should be noted that, in the existing water generator set, it is necessary for the water flow to drive the water wheel to rotate, and then drive other equipment to realize the power generation operation. When the water wheel is linked in the water, its blades always face one side of the water flow. When rotating, the blades on the side facing away from the water flow slide in the water, and there is a great water resistance, resulting in the waste of water energy and the inability to realize efficient power generation. In order to solve this problem, a linkage power generation component 4 and a transmission component 5 are provided in the present scheme. The linkage power generation component 4 is driven to be linked by the transmission component 5, and the power generation operation is realized in cooperation with the external power generation mechanism. When the transmission component 5 is linked, when the water-blocking blade 52 rotates to the water-facing surface, its cross-section and the water flow are maximized. When rotating to the back surface, the water-blocking blade 52 rotates on the transmission frame 41 under the limiting action of the limiting unit. At this time, its cross-section and the water flow are minimized, so as to avoid excessive water resistance between the water-blocking blade 52 and the water flow and waste of energy, thereby maximizing the power generation efficiency.

[0030] Specifically, in this embodiment, this scheme mainly includes a support rod 1, a limit rod 2, a gear protection box 3, a linkage power generation component 4 and a transmission component 5. When in use, the support rod 1 is used to support the entire device, and the water-blocking blades 52 in the transmission component 5 come into contact with water and push the transmission component 5 to be linked as a whole, thereby driving the transmission frame 41 in the linkage power generation component 4 to rotate, and synchronously driving the driving gear 43 to rotate, and the driven gear 44 is driven to be synchronously linked through the driving gear 43, and the driven gear 44 cooperates with the external power generation mechanism to realize the power generation operation, which is simple and efficient.

[0032] The abutment rod 54 is fixed at the end point of the docking plate 53, and the slider 55 of the spherical structure is rotatably connected to the abutment rod 54. The slide groove 56 is a special-shaped structure and is concavely arranged on the outer wall of the limiting rod 2. The slider 55 slides and abuts in the slide groove 56.

[0033] In this embodiment, the slide block 55 is limited by the slide groove 56 so that the water blocking blade 52 can deflect to a certain extent when rotating along the outer wall of the limiting rod 2, thereby adjusting the size of the cross section between the water blocking blade 52 and the water flow.

[0034] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the linkage unit includes a transmission rod 42, a driving gear 43 and a driven gear 44;

[0035] The transmission rod 42 is fixed to one end of the transmission frame 41 and rotatably sleeved on the outside of the support rod 1 . The driving gear 43 is coaxially fixed to the transmission rod 42 . The driven gear 44 is rotatably connected to the gear protection box 3 and meshes with the driving gear 43 .

[0036] In this embodiment, the driving gear 43 is driven to rotate by the transmission rod 42, and then the driven gear 44 is driven to mesh and link with each other through the driving gear 43, and the driven gear 44 cooperates with the external power generation mechanism to realize the power generation operation.

[0037] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the abutment rod 54 is composed of two round rods, one of which is slidably connected in the inner cavity of the other round rod, and a spring is arranged between the two round rods.

[0038] In this embodiment, the round rod is pushed by the elastic force of the spring, so that the slider 55 can always abut against the sliding groove 56.

[0039] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the driving gear 43 and the driven gear 44 are both helical gears, and lubricating grease is provided between them.

[0040] In this embodiment, the helical gears are provided to increase the stability and service life of the gears during meshing and linkage, and reduce noise.
