Abstract
The utility model relates to a blade signal feedback device used in products such as vertical well type and shaft extension type hydroelectric generating sets and shaft extension pumps provided with rotary blades. The blade signal feedback device is matched with a main shaft of a rotary blade; the main shaft is provided with a radial hole and an axial hole which are communicated with each other; the blade signal feedback device comprises a feedback rod, a slide block and a shifting fork, wherein the feedback rod is arranged in the axial hole of the main shaft, the slide block is movably sleeved on the main shaft, and the feedback rod is connected with the slide block through a connecting rod, one end of the shifting fork is connected with the slide block, and the other end of the shifting fork is matched with an angular displacement sensor. The blade signal feedback device is capable of realizing signal taking out in the entire rotation process of a blade and accurately measuring the movement state of the blade and has the advantage of sensitiveness in feedback.
Description
Technical field
The utility model belongs to the hydraulic turbine generator technical group field, particularly relates to a kind of blade signal feedback device that is applicable to that products such as being provided with the vertical shaft type that changes slurry, shaft extension formula hydraulic generator unit, shaft extension pump uses.
Background technique
In products such as the vertical shaft type that is provided with the commentaries on classics oar, shaft extension formula hydraulic generator unit, shaft extension pump, need change the switching of blade, to form favourable water inlet condition according to different flows and head.Because the rotary main shaft of the said goods links with speed increaser or retarder, so usual manner can't take out the feedback signal of blade, how to address the above problem, and become that electricity power enterprise is badly in need of solving and one of problem of concern.
Summary of the invention
At the above-mentioned problems in the prior art, the purpose of this utility model is that design provides a kind of blade signal feedback device, to obtain the overall process signal that blade rotates, is convenient to control the switch of blade.
Described blade signal feedback device, this device matches with the main shaft that changes oar, main shaft is provided with radial hole and axial bore, described radial hole and axial bore communicate, and described device comprises feedback rod, slide block and shift fork, it is characterized in that described feedback rod is arranged in the axial bore of main shaft, described slide block is actively socketed on the main shaft, be connected by connecting rod between described feedback rod and the slide block, described fork one end is connected with slide block, and its other end matches with angular displacement sensor.
Described blade signal feedback device is characterized in that described angular displacement sensor is fixed on the support of body.
Above-mentioned blade signal feedback device, slide on main shaft by the drive slide block that moves forward and backward of being located at the middle feedback rod of main shaft, slide block drive the rotation of fork with respect to endwisely slipping of main shaft, thereby drive the rotation of angular displacement sensor, realize that the overall process signal that blade rotates takes out, can accurately measure the motion state of blade, have the sensitive advantage of feedback.
Description of drawings
Fig. 1, Fig. 2 are structural representation of the present utility model;
Among the figure: 1-fork, 2-feedback rod, 3-main shaft, 3a-axial bore, 3b-radial hole, 4-slide block, 5-connecting rod, 6-angular displacement sensor.
Embodiment
