Description

  The present invention provides a reversible water tank 1 that can be used to promote the flow of water in a certain section such as a river with a small slope, or to automatically sprinkle water in a kitchen garden or gardening.

  Rivers with low gradients have traditionally been considered to promote the flow of water, increasing the flow velocity by narrowing the river width in stages.

  As water sprayers for kitchen gardens and gardening, it is conceivable to use a timer to supply water or to use a float and a valve.

[Source: Quoted from “Report on the Yodo River Comprehensive Development Project (Yodo Dam Construction) Yodo River System Development Project Review 2003”], “Land Improvement Plan Design Criteria Design (Waterway Construction Part 1) If the flow velocity is 0.45 to 0.9 m / sec, sedimentation of suspended sediment will not occur, and if the average flow velocity in the waterway is 0.7 m / sec or more, it is said that plant growth that significantly impedes flow can be prevented. Yes.

  For rivers with a small gradient, such as increasing the flow speed by narrowing the width of the river step by step, when the amount of water in the river decreases, the water stops flowing and weeds grow.

  In addition, there are things such as kitchen gardens and gardening that use a timer to supply water, and those that use floats and solenoid valves to supply water, but maintenance is required such as where electricity cannot be used or breakdown due to electric leakage etc. There are dangers in unattended automation.

  In order to solve these problems, the longitudinal section composed of the side plate A, the diagonal bottom plate B, and the upper opening side C is a triangular water tank, and the water tank is located closer to the side plate than the center of the diagonal bottom plate B. A supporting shaft 2 and a supporting bearing 3 are provided, and a water tank reversal return weight 5 is attached to or near the bottom formed by the side plate A and the slanted bottom plate B, and the weight of the weight is changed. Water is supplied from the water supply port 4 at the top of the opening side C, and when the amount of water in the water tank reaches the required amount, the water tank reverses with the support shaft 2 supporting the water tank as a base point, and water is immediately drawn from the top of the water tank. A reversible water tank 1 that discharges everything is provided.

  By providing the reversible water tank 1 in a certain section such as a river with a small gradient, water and the like are discharged from the reversible water tank 1 to the river all at once, thereby promoting the flow rate of water and reducing sedimentation of floating earth and sand. You can make improvements.

  Moreover, watering such as gardening can be automatically performed by adjusting the amount of water supplied to the water tank of the reversible water tank 1 and setting the time for the water tank to automatically reverse.

  As an effect of general use of the reversible water tank 1 of the present invention, there are various purposes such as the purpose of not storing and discharging the required amount of water at the required intervals, and causing flow waves by discharging water etc. at once. It can be used in various ways.

  By providing the reversible water tank 1 of the present invention in a fixed section such as a river with a small slope, water can be discharged from the reversible water tank 1 at a stretch, and rivers stagnated by floating earth and sand can be cleaned and the environment can be improved.

  Even in the case of watering such as kitchen gardening and gardening, the amount of water to be stored in the reversible tank 1 is determined according to the amount of watering to the crop and the number of pots, and the size of the tank is set. By discharging water or the like into the fixed water tank 10 or the like, and supplying a fixed amount of water or the like from the fixed water tank 10 to each crop, it is possible to supply water to the crops in an unmanned manner by a desired amount.
