The level control tank 10 is provided to provide a space in which the inflow / outflow of water occurs. However, a conventional ballast tank may be a component fixed to a floating bridge. In particular, As shown in Patent Document 10-0424277, it is possible to utilize a floating housing structure (see Figs. 1 and 2) in which a partition wall is provided in the housing in the floating state in the lateral and longitudinal directions so that a plurality of closed cells are independently formed have.

According to the float bridge structure of the present applicant as described above, each of the plurality of closed cells can function as a ballast tank or the water leveling tank 10 of the present invention. In addition, for each of the components described in detail below, It can be easily understood that the top plate can be structurally changed even in a divided form covering only the level control tank 10 portion.

4, a middle portion (which can be formed by one or more cells) of a plurality of cells sealed by the horizontal and vertical partition walls, that is, a portion disposed at the central portion of the floating bridge is referred to as a main water level Level tank 12, 13, 14 and 15 as the adjustment tank 11 and a portion (formed by one or more cells) disposed at the corner of the floating bridge.

According to the above-described main and sub water level control tanks 11, 12, 13, 14 and 15, the basic balance of the floating water can be balanced through the weight of water filled in the main water level control tank 11, The detailed balance of the front and rear, left and right directions can be adjusted by the amount of water (water amount) filled in the sub level control tanks 12, 13, 14, 15 located at the four corners.

With reference to the registered patent of the present applicant, since the floating bridging housing for the main and sub level control tanks 11, 12, 13, 14 and 15 can be made of FRP (fiber reinforced plastics) It should be noted that the whole floats in the water or has no problem filling the water.

The water in the main level control tank 11 can be discharged to the outside (river, sea, etc.) through the automatic valves (v3 and v14) when the main pump 21 operates according to the automatic valve opening /

The pumping means 20 is capable of supplying or discharging the entire main and sub level control tanks 11, 12, 13, 14, 15 through a single main pump 21, In particular, it is possible to construct such a line at a low cost, and in particular, to allow the sub-level adjustment tanks 12, 13, 14 and 15 to be discharged only to the main level tank 11 without being directly discharged to outside, Thereby making it possible to simplify the second level adjustment line 23 as much as possible.

Hereinafter, the function of the balance reinforcement floating bridge according to the present invention by the sensing means and the control means will be described with reference to FIG.

The sensing means 30 senses the level of each of the level control tanks 10, namely, the main and sub level control tanks 11, 12, 13, 14 and 15, the horizontal level of the floating bridge, The control means 40 adjusts the horizontal level of the floating bridge so that the level sensing sensor is installed inside each of the main and sub level control tanks 11, 12, 13, 14 and 15, A level sensor may be installed on the top plate, or a water level sensor may be installed at regular intervals along the bottom of the floating bridge.

According to the detecting means 30, when the water in the specific tank among the main and sub water level adjusting tanks 11, 12, 13, 14 and 15 is insufficient, it is indirectly detected that the floating tank bridge is not balanced, The unbalanced part of the front and back, right and left, can be detected directly, or the level difference of the partial level of the floating float can be detected.

The control means 40 controls the main and sub level control tanks 30 based on the information measured by the sensing means 30 (the amount of water in the level control tank 10, the floating status of the floating bridge 10, (10) by controlling the pumping means (20) so that water is sucked or discharged from a specific tank among the water storage tanks (11, 12, 13, 14, 15) (Amount of water) can be adjusted.

On the other hand, if the water in the level control tank 10 is circulated in the tank for a long period or stays for a long time, water pollution may occur, and when the polluted water in the level control tank 10 is discharged to the outside The sensing means 30 may be used to measure the water quality in the water level control tank 10 by using a biochemical oxygen demand (BOD) detector, a chemical oxygen demand (COD) (Not shown) such as a pH meter, a pH meter, and the like. By controlling the pumping means 20 when the water quality information measured by the water quality measuring means is below a predetermined level, The water in the tank 10 may be drained and then sucked outside.

Further, when the water in the level adjustment tank 10 is in a stagnant state during the winter season, the pumping means 20 may be frozen or the tank may be damaged due to the expansion of the volume, As a measure for this, the sensing means 30 may include temperature sensing means (not shown) such as a temperature measuring device for measuring the temperature in the level control tank 10, and temperature information measured by the temperature sensing means The control means 40 operates the pumping means 20 to circulate the water and the external water in the level control tank 10 to prevent the water in the level control tank 10 from freezing.

As shown in FIG. 12, the floating bridges may further include a box-shaped support leg 50 for preventing the bottom surface thereof from being directly in contact with the ground surface, so as to construct a floating bridge on the ground, When carrying a floating bridge, it is possible to prevent the floating bridge from being damaged by preventing direct contact between the ground and the floor of the floating bridge.

The support leg 50 includes a first support portion 51 integrally extended from the floor of the floating bridge and having a closed space formed therein, and a space formed by the lower surface of the support leg 50 and divided by the plurality of barrier ribs. And a second support portion 52 integrally extending from the first support portion 51. The first support portion 51 provides buoyancy to float the float due to the support leg 50, The water can flow in and out through the through hole in the state where the lower surface of the second support part 52 is open. Therefore, the pressure applied to the support leg 50 side by the water flow in the state where the floating water pipe is immersed in water It is possible to help the stable floating level of the floating bridge.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, .
