Description
Technical Field
The utility model relates to a device that is used for interception filth in power station hydraulic generator water inlet, pump station water inlet or the river course, concretely relates to trash rack at automatically regulated inclination.
Background
The trash rack is generally arranged at a water inlet of a hydraulic generator of a hydropower station, a water inlet of a pump station or in a river channel and used for intercepting dirt so as to ensure the running safety of the hydraulic generator or the cleanness of water lifting of the pump station. The trash racks which are commonly used at present are vertically arranged and also obliquely arranged at a certain angle, and the two types of trash racks are fixed at a fixed angle. The water level is the same, and the water passing section of the trash rack arranged obliquely is larger than that of the trash rack arranged vertically. In the flood season, the water level is always at a high water level line, the water level is higher at the moment, the trash rack can generally ensure a larger water passing section, in the dry season, the water level is always at a low water level line, the water passing section of the trash rack is greatly reduced when being compared with the high water level, and the water consumption in the downstream is difficult to ensure.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an automatically regulated trash rack at inclination to the above-mentioned not enough and defect of prior art to solve above-mentioned problem.
The utility model provides a technical problem can adopt following technical scheme to realize:
the trash rack capable of automatically adjusting the inclination angle comprises a trash rack body and is characterized in that the bottom of the trash rack body is rotatably connected to the bottom of water through a hinged component, and a floating body is arranged at the top of the trash rack body.
In a preferred embodiment of the present invention, the trash rack further comprises an upstream limiting device for limiting the maximum rotation angle of the trash rack and a downstream limiting device for limiting the minimum rotation angle of the trash rack.
In a preferred embodiment of the present invention, the upstream limiting device and the downstream limiting device are respectively limiting bars disposed at the side portions of the trash rack.
In a preferred embodiment of the present invention, the angle between the trash rack and the horizontal plane is 40 ° to 90 °.
In a preferred embodiment of the present invention, the hinge member includes a fixing base fixed under the water bottom and a first hinge shaft connected to the bottom of the trash rack.
In a preferred embodiment of the present invention, the floating body is connected to the top of the trash rack by a hinge.
In a preferred embodiment of the present invention, the hinge is a second hinge, and the top of the floating body is rotatably connected to the connecting edge of the top of the trash rack through the second hinge.
In a preferred embodiment of the present invention, the floating body has a hollow structure.
In a preferred embodiment of the invention, the floating body is less dense than water.
Due to the adoption of the technical scheme, the beneficial effects of the utility model reside in that: different from the prior art, the trash rack can rotate around a hinge shaft part at the bottom of the trash rack, and the trash rack automatically rotates under the action of the floating body. When the water level is at a low water level, the trash rack can still provide a large water passing section by adjusting the angle of the trash rack.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
Fig. 1 is a schematic structural view of a trash rack capable of automatically adjusting an inclination angle according to the present invention.
Fig. 2 is a side view of fig. 1.
Fig. 3 is a side view of the present invention at high water levels.
Fig. 4 is a side view of the present invention at a low water level.
Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further explained below.
Referring to fig. 1 to 4, the trash rack with an automatically adjustable inclination angle includes a trash rack 1, an upstream limiting device 10 for limiting a maximum rotation angle of the trash rack 1, and a downstream limiting device 20 for limiting a minimum rotation angle of the trash rack 1. The upstream limiting device 10 and the downstream limiting device 20 are respectively limiting barrier strips 1a arranged on the side parts of the trash rack 1. Preferably, the upstream stop device 10 and the downstream stop device 20 are an upper stop ring and a lower stop ring, respectively. Specifically, the upper limit ring and the lower limit ring are restrained by the upper limit ring and the lower limit ring when the trash rack 1 rotates to the limit position, and particularly the upper limit ring can prevent the inclination angle of the trash rack 1 from exceeding 90 degrees.
The bottom of the trash rack 1 is rotatably connected to the bottom of water through a hinge component 2, and the hinge component 2 comprises a fixed seat 2a fixed to the bottom of water and a first hinge shaft 2b connected to the bottom of the trash rack 2. The included angle between the trash rack 3 and the horizontal plane is 40-90 degrees.
The top of the trash rack 1 is provided with a floating body 3, the floating body 3 in the embodiment is a cavity structure, and the density of the floating body 3 is smaller than that of water. The floating body 3 is connected to the top of the trash rack 1 through the hinge piece 4, the hinge piece 4 is a second hinge shaft, and the top of the floating body 3 is rotatably connected to the connecting edge 5 at the top of the trash rack 1 through the second hinge shaft. Specifically, the second hinge shaft ensures that the bottom surface of the floating body 3 is parallel to the horizontal plane.
The working principle of the utility model is as follows:
when the water level rises, the floating body 3 floats upwards along with the water level, the trash rack 1 rotates around the first hinge shaft 2b of the trash rack 1 under the action of the floating body 3, the inclination angle of the trash rack 1 gradually increases, and when the trash rack 1 rotates to a vertical state, the upper limit ring can limit the trash rack 1 to continue rotating so that the trash rack 1 keeps a vertical state. When the water level descends, the floating body 3 descends along with the water level, the trash rack 1 rotates around the first hinge shaft 2b of the trash rack 1 under the action of the floating body 3, the inclination angle of the trash rack 1 gradually becomes smaller, and when the trash rack 1 rotates to an inclination angle of 40 degrees, the lower limiting ring limits the rotation of the trash rack 1, so that the trash rack 1 keeps the inclination angle.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
