Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a simple waterway dust remover, and more particularly to a dust remover installed in a small waterway or the like.

[Conventional technology]

Conventionally, a dust remover installed in a narrow waterway such as a water intake passage at a pumping station is of a wire rope type or an endless chain type, which is a method of scraping dust from the water.

[Problems to be solved by the device]

The previously used dust removing device is simply a device designed for a large water canal and is made small. Since it is originally for a large water canal, the structure is complicated and the device itself is large. Therefore, maintenance and inspection are not easy and the price is high.

Further, in the wire rope type, since the rake moves up and down on the screen through the roller, the rake itself is heavy and the roller is made large so that dust attached to the screen can be pushed down.

Therefore, in the small water channel, the ratio of the roller width to the water channel width is large, and there is a problem that the effective scratch width cannot be obtained.

Further, in the endless chain type, there is a problem that the radius of the rake reversal portion in the lower part of the water channel is large and the area of the bottom of the water channel where scratches cannot be scratched is large, so that the efficiency is not good in the small water channel.

In view of these circumstances, the present invention aims to provide a dust eliminator for a simple watercourse, which eliminates the above-mentioned difficulties, has a simple structure suitable for small waterways, is inexpensive, and is excellent in operability and maintenance. It was developed.

[Means for solving the problem]

In order to solve the above-mentioned problems and to achieve the object, this invention has a pair of pillars on which a girder-shaped platform with transverse girders is arranged across a water channel, and hinge brackets are provided at the upper ends of the pillars. The hinge bracket is pivotally attached to the lower rear part of the cylinder, and the front and lower parts of the hinge bracket are pivotally attached to the tip end of the rod that moves vertically on the front part of the column, and the hinge bracket is moved from the horizontal state to the vertical direction by advancing and retracting the rod. It is configured to be swingable, and a swing base is horizontally fixed between the upper parts of both hinge brackets, and a drive shaft driven by a motor is horizontally installed on the swing base and is vertically driven at both ends of the drive shaft. A lifter is vertically slidably fitted to both of the lift drives in a direction orthogonal to the hinge bracket, and a rake is horizontally installed between the lower ends of the lifters. A plurality of boards are erected along the length of the board, and a board is stretched on the board. The technical means was taken as a simple waterway dust removal device with a structure that scratches dust, and guide rollers are axially attached to the lower rear parts of the left and right cask boards.

[Action]

The present invention configured as described above has the following operation.

 The gate type pedestal is laid over with the front facing the upstream side of the waterway.

The dust screen is arranged so as to flood the lower part and cross the water channel. As a result, dust that has flowed through the waterway is caught on the dust screen.

The lower part of the lifting rod is submerged, and the rake is submerged. When the driving mechanism is driven to raise the lifting rod, the rake slides up the rollers to the outer frame of the dust screen and rises to scrape up the dust caught on the dust screen. At the same time as scraping, the dust is automatically dropped and collected in the collection unit.

Next, when the cylinder of the swing part is operated to swing the upper part of the hinge bracket rearward, the swing base swings,
In conjunction with this, the lower end of the lifting rod swings upward with the bearing portion as the swing fulcrum. Naturally, the rake also works together.

Next, when the lower end of the elevating rod is lowered forward to reach the lower limit position, if the hinge bracket swings the upper part forward with the hinge part as the swing fulcrum, the rake moves in conjunction with the dust screen lower front part. Submerge in water until the rollers come into contact and return to their original position. Thereafter, by repeating this operation, the dust caught on the dust screen can be continuously scraped up.

〔Example〕

An embodiment of the present invention will be described with reference to the drawings. First
The drawing is a front view of the apparatus, and FIG. 2 is a side view. The gate mount 2 of the dust remover 1 for the simple waterway is fixed to the both sides G of the waterway W by the fixed bases 2C, 2
The horizontal girder 2B is fixed to the upper part of the right and left columns 2A, 2A fixed via C, and the columns 2C and 2C at the lower end of the columns 2A and 2A are fixed to both banks via bolts 2D. can do.

Bearings 3, 3 respectively arranged at the upper ends of the columns 2A, 2A
The hinge brackets (4, 4) are swingably disposed via the. Further, electrically automatically controlled cylinders 5 and 5 are arranged on the front surfaces of the columns 2A and 2A, and the piston rods 5A and 5A of the cylinders have all the end portions at the lower front portions at both ends of the hinge brackets 4 and 4. The hinge brackets 4, 4 swing forward and backward by the forward and backward movements of the piston rods 5A, 5A.

A grid-like dust screen 6 is provided between the columns 2A and 2A.
However, the lower part is arranged so as to cross the water channel W and be submerged.

A rocking base 7 is horizontally mounted between the hinge brackets 4, 4, and a drive unit 8 is arranged on the rocking base 7.

The drive device 8 is a drive shaft 8B driven by an electric motor 8A.
Elevating drive parts 8C, 8C for vertically moving the elevating rods 9, 9 by meshing gears are provided at both ends of the elevating rods 9, 9 and the elevating rods 9, 9 are vertically movably mounted on the elevating drive parts 8C, 8C, respectively. . Then, when the swing base 7 swings backward, the lower ends of the lifting rods 9, 9 swing upwards apart from the dust screen 6, and when the swing base 7 swings forward, the lifting rod 9 moves upward. The lower end portions of 9 and 9 descend and approach the dust screen 6.

A rake 10 for scraping up dust is laid horizontally on the lower end portions of the both elevating rods 9, 9, and the rake 10 has a plurality of side surface substantially triangular rods 10D along the length at the upper part of the horizontal axis 10C. , 10D… are erected. The boards 10D, 10D, ... Are substantially isosceles triangles as shown in the side view in FIG.
It is fixed to C, and the upper end surface is slightly recessed in the rear part from the longitudinal center part, and as a whole, the upper end surface is inclined rearward and downward with respect to the elevating rod. As shown in FIG. 2, the rear end surface of the scraping plate 10E is located in the gap portion of the dust screen 6 as shown in FIG.
E The rod portion of the screen 6 is scraped off so that the rear end surface of the screen 6 is located behind the entire surface of the screen 6, and is formed in a substantially comb-tooth shape. In order to maintain a position so that a part of the rear end surface of the scraping plate 10E is slightly behind the entire surface of the screen 6, as shown in FIG. It is pivoted. When the hoisting rods 9, 9 rise, the rake 10 rises along the dust stop screen 6 while slidingly contacting the roller 11, and the dust caught on the dust stop screen 6 can be scraped up. Conventionally, the rake is a combade or a mugwa, and a comb-like one for scratching, but since the scraping plate 10E in this invention has a wide front and rear width, it is possible to easily scrape even fine dust such as fallen leaves accumulated at the bottom of the waterway. it can.

This embodiment having the above-mentioned structure has the following operation.

Electric motor 8A and electric cylinders 5, 5 of the drive unit 8
Is automatically controlled by a control device of a separately arranged operation panel and operates, for example, at a fixed time or a set time.

Therefore, in the state shown in FIG.
When dust is caught on the electric motor 8A of the drive device 8 is automatically driven at a specific time to rotate forward, the elevating rods 9, 9 rise, and the rake 10 is caught on the dust stop screen 6. Scrape up the dust. The scraped dust falls to the upper rear portion of the dust screen 10 and is automatically collected by a conveyor (not shown).

When the rake 10 reaches the upper end of the dust screen 6, the electric motor 8A automatically stops, and instead the electric cylinder 5,
5 is activated and the tips of the piston rods 5A, 5A push up the front of the hinge brackets 4, 4 so that the support shafts of the bearings 3, 3
The swing base 7 swings backward (to the left in FIG. 2) about 3A as a fulcrum. .. and the rake 10 ascends from the dust screen 6 as shown by a virtual line 10A in FIG. When the swing limit is reached, the action of the electric cylinders 5, 5 automatically stops, and instead the electric motor 8A starts reverse rotation. As a result, the elevating rods 9, 9 descend obliquely, the rake descends to the position shown by the imaginary line 10B in FIG. 2, and the electric motor 8A automatically stops at the lower limit. Even at this stage, since the rake is still above the water surface, the electric cylinder 5 should be retracted to the original position without affecting dust caught on the screen 6 after scratching up with the rake 10. Can be put back by.

By continuously performing the above steps, the dust screen can be easily removed.

In the present invention, it goes without saying that the drive device and the electric cylinder can be changed to another drive mechanism.

[Effect of device]

As described above, the present invention has the following excellent effects.

(1) In the conventional wire rope type and endless chain type, since the rake moves up and down in front of and behind the screen, there is a drawback that the front and rear width of the device becomes wide, and the rake under the screen moves from rear to front. In order to pass through, there is a difficulty such as providing another dust stop mechanism at the lower front part of the screen, but in this device, the rake only rises in front of the screen, so the entire device is suitable for a small waterway. There is an effect that it can be made compact.

(2) Since the lifting rod is simply slid up and swung, the drive system of simple operation is excellent in operability, maintainability, and manufacturing cost.

(3) Since the rake lifted onto the screen is lowered from above the water on the upstream side to the front lower part of the screen through the swing mechanism, the rake can be operated without being affected by dust adhering to the screen.

In addition, the rake can be swept wide,
It is also possible to scrape from the bottom edge of the screen.

(4) A series of operations can be set in advance to perform unmanned operation operation by automatic control, and the labor of the manager can be reduced especially in mountainous areas.
