A float 200 is connected to the gear type or mechanical water level gauge in the relay pump station, and the connection is usually made by fastening the connection part 200p at the upper end of the float with a connection line 200w. It is desirable to impart significant weight and buoyancy to the float 200 . For example, the specific gravity is 0.6; Weight 3.0 kg; The length is 50cm; it can be increased or decreased appropriately according to the situation of the field as a standard, and PVE, PP, ABS, PE, etc. are possible as members, and if necessary, a weight such as a metal member is inserted inside, or vice versa. It is possible to form a gas (air) layer to impart buoyancy. On the other hand, after installing such a configuration, there are cases where smart technology is used to monitor whether the configuration is operating or not. For example, after installing a CCTV camera and an actuator on the water level gauge at a relay pump station, and installing a related application on a terminal such as a smartphone through Wifi or Internet online from a distance, the operation status can be monitored and controlled. it can be See FIG. 1A in this regard.

In the guide pipe 300 , an upper end 310 of the guide pipe and a lower end 320 of the guide pipe may be opened. Then, the float 200 is inserted into the guide pipe 300 to move in the vertical direction. Accordingly, the float 200 can ascend and descend in the vertical direction while floating or sinking along the height of the sewage inside the guide pipe 300 . Of course, the size of the outer periphery of the float body 210 of the float 200 should be small so as not to stop in friction with the inner periphery of the guide pipe 300 . According to the role of the guide pipe 300 installed as described above, the penetration of the external scum 20 into the guide pipe 300 is minimized, so that the scum 20 can be adhered to the float body 210 . Protect the float 200 from In addition, when the rise and fall of the float 200 is shaken by external influences and does not operate stably due to fluctuations caused by the change in the amount of inflow of the sewage 10 being severe, the guide pipe 300 prevents the float from external influences. Protect (200).

In the case of the scums 20 and 21 floating above the water level of the sewage 10 when the water level gauge is operated for a long period of time, the upper end of the guide pipe 310 is higher than the water level of the sewage 10, so it is blocked by the guide pipe 300, but , when the fluctuation of the sewage 10 is severe, the floating scum 20 goes down under the water surface of the sewage 10 and penetrates into the lower end of the guide pipe 320, or even if there is no fluctuation, the scum 20 with a large specific gravity Silver penetrates into the lower end of the guide pipe 320 and accumulates little by little, and when cleaning is not performed for a long period of time, eventually, it may be firmly adhered to the inner wall of the body of the guide pipe 300 and cause a problem in the operation of the water level gauge.

1B and 2 , a float projection 220 is provided on the outer peripheral surface of the float 200 . The float protrusion 220 may be formed by directly protruding the outer circumferential surface of the float body 210 , or may be fixed by attaching to the outer circumferential surface of the float body 210 after separately manufacturing the protrusion shape. The role of the float protrusion 220 is to forcibly wipe, push, scrape, or crush foreign substances such as scums 20 and 22 attached to the inner wall of the guide pipe 300 during the lifting and lowering movement of the float 200 . can be removed by See Patent Publication No. 93208 (2016.08.08).

First, in FIGS. 3 and 4 , the float 200 has an expansion and contraction means capable of stretching (increasing or decreasing the length) in the vertical direction. To this end, the float body 210 of the float 200 is an independent float body. 211 and the lower float 212 are configured separately, and the float upper body 211 is disposed above the float lower body 212 , and accordingly, the lower float 212 is located below the float upper body 211 . And the float 200, that is, the float body 210 includes a configuration of a telescopic expansion device 230p, and the expansion device 230p includes a coupling shaft 231, a coupling shaft bolt fixing groove 231p, a coupling hole ( 232), a lower body bolt fixing groove (231q), and a fixing bolt (231r).

At this time, the size (length) of the float body 210 can be adjusted by inserting (inserting) the coupling shaft 231 into the coupling hole 232 by a required depth.

After the float upper body 211 and the float lower body 212 are assembled and size adjustment is made, the configuration of a fixing device may be included so that the state can be maintained. The fixing device of the drawing example consists of a coupling shaft bolt fixing groove 231p, a lower body bolt fixing groove 231q and a fixing bolt 231r, and the fixing bolt 231r is provided with a bolt having a predetermined length, and the lower body bolt The fixing groove 231q is drilled in the horizontal direction in the body of the float lower body 212 to correspond to the outer shape of the fixing bolt 231r, and the coupling shaft bolt fixing groove 231p is vertically along the body length of the coupling shaft 231. A plurality of coupling shaft bolt fixing grooves (231p: 231p1, 231p2, 231p3, 231p4...) spaced apart from each other are provided by being perforated in the horizontal direction, respectively. And at the time of assembling, the coupling shaft 231 is fitted into the coupling hole 232, and at the same time, the lower body bolt fixing groove 231q is positioned horizontally and in a straight line in any one selected from the plurality of coupling shaft bolt fixing grooves 231p. , the coupling shaft bolt fixing groove (231p) and the lower body bolt fixing groove (231q) are inserted at once by the fixing bolt (231r) to be fixed.

Through the above-described configuration, it is possible to select a float 200 of an appropriate size for the facility situation of the relay pump station water level gauge on the spot. In particular, the float 200 for the size (length) of the guide pipe 300, that is, the float body. It is necessary to determine the size ratio of 210, to consider the buoyancy of the float 200, or to determine how much the upper upper part of the float 211 above the float 200 is exposed above the water surface. Appropriate size can be found and applied. In addition, when the float 200 is not normally used, for example, in the case of distribution and storage, the volume can be reduced for convenience.

And when using the guide pipe 300, inserting (inserting) the float 200 in the guide pipe 300; It may also be included.

In addition, in the case of inserting and using the float 200 in the guide pipe 300, another embodiment will be looked at together. Conventionally, the float protrusion 220 provided on the outside of the float body 210 is removed by scraping and removing the scum 20 adhering to the inner wall of the guide pipe 300 with a natural force that is the mass or buoyancy of the float 200 itself. Although proposed, in reality, the float projection 220 is caught in the scum 20 and is often stuck again. As a result, the operation itself of the water level gauge may become impossible. Therefore, it is necessary to forcibly input an external force.

In FIG. 3 , a motor accommodating room 241 provided as a space is formed inside the float 200, that is, the float upper body 211 of the float body 210, and a rotatable motor 242 is mounted therein, and the motor 242 ) is provided as a coupling shaft 231 as the rotation axis is vertically downwardly arranged. At this time, the coupling shaft 231 becomes a rotatably bearing on the bottom surface of the float upper body 211 and is closely and watertightly assembled so that external water does not penetrate. And the power supplied to the motor 242 is transmitted from the outside through the upper connecting portion 200p and the connecting line 200w, and at this time, the connecting portion 200p and the connecting line 200w are rotationally coupled in which mutual rotation can be made. To achieve, power supply, etc. can be cited in the prior art for supplying power between the rotating body.

According to the above configuration, in FIGS. 4 and 5, when power is supplied by controlling the motor 242 to rotate, the float upper body 211 and the float lower body 212 rotate in opposite directions to the float body 210. It is possible to remove the scum 20 strongly attached to the inner wall of the guide pipe 300 while forcibly rubbing the float protrusion 220 formed on the outside of the scum while rotating.

That is, the upper float protrusion 221 provided in the upper float 211 and the lower float protrusion 222 provided in the lower float 212 rotate in opposite directions. In order to more powerfully clean the scum 20 by the principle of rotating in opposite directions, the upper body side float protrusion 221 rotates in a counterclockwise direction (s1), and the lower body side float protrusion 222 rotates in a clockwise direction (s2). An example of rotating with is shown in FIGS. 4 and 5 .
