Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in figures 1 and 2, the reservoir suitable for agricultural irrigation in arid regions comprises a reservoir wall 1, a reservoir bottom 2, a PVC plate 6, a support 7 and a wood block 11, wherein the reservoir bottom 2 is arranged at the lower end of the reservoir wall 1 to prevent water leakage, a water outlet 3 and a sewage outlet 4 are arranged at two sides of the reservoir wall 1, a U-shaped groove 5 is arranged under the water outlet 3, the reservoir wall 1 is provided with the water outlet 3, a valve is installed, water can be conveniently taken, the U-shaped groove 5 is arranged under the water outlet to avoid water and soil loss caused by direct low splashing to the ground when water is taken, the support 7 is arranged at the top end of the reservoir wall 1 at the side 2, the reservoir wall 1 and the support 7 are fixedly connected, the connection strength is improved, the breakage and damage are prevented, the support 7 is provided with a connecting rod rotating shaft 8 through the connecting rod, the fixing rod 9 is arranged at the upper end of the rotating shaft 8, the fixing, the PVC plate 6 is prevented from being loosened, the rope 10 is arranged on the lower side of the inner end of the PVC plate 6, the other end of the rope 10 is connected with the wood block 11, multiple functions can be achieved by utilizing a simple buoyancy principle, when the water level of the reservoir is lower than a high water level 12, the PVC plate 6 is automatically opened to be in a V shape, the water collection area is enlarged, and the water collection efficiency is greatly improved; after water collection is completed, the PVC plate 6 is horizontally closed, so that sundries can be prevented from falling into polluted water, and potential safety hazards can be eliminated.

The inner surfaces of the pool wall 1 and the pool bottom 2 are both provided with waterproof coiled materials, so that leakage and seepage can be prevented.

The terminal surface forms 15-30 contained angles with the horizontal plane in the bottom of the pool 2, can deposit the pollutant in the bottom of the pool lower, utilizes drain 4, directly washes away impurity etc. out, and in winter, open drain 4 and can empty the retaining fast, prevent to freeze the frost crack cell body.

The water outlet 3 is arranged at the high position of the pool bottom 2, the sewage outlet 4 is arranged at the low position of the pool bottom 1, and the water outlet 3 and the sewage outlet 4 are both provided with valves, so that the overall utilization efficiency is improved.

The support 7 comprises a bottom edge and a supporting edge, the supporting edge is provided with the PVC plate 6, the supporting edge is not connected with the PVC plate 6, only one supporting function is provided, the height of the supporting edge is consistent with the overall height of the fixing rod 9 and the rotating shaft 8, and the PVC plate 6 can be in a horizontal state.

The PVC plate 6 and the bracket 7 form a rotating structure through the fixed rod 9 and the rotating shaft 8, when the water level of the water storage tank is lower than a high water level 12, the PVC plate 6 automatically rotates and is opened to be V-shaped, the water collection area is enlarged, and the water collection efficiency is greatly improved; after water collection is completed, the PVC plate 6 rotates, impurities can be prevented from falling into polluted water bodies after horizontal closing, and potential safety hazards can be eliminated.

The length of the fixed rod 9PVC plate 6 is less than that of the PVC plate 6 outside the supporting edge, the PVC plate 6 is fixed on the fixed rod 9 through a nylon cable tie, the length of the PVC plate 6 outside is 1.2-1.5 times of that of the inside, and the weight of the PVC plate 6 outside is less than that of the PVC plate 6 inside and the weight of the wood block in the natural state.

When two PVC boards 6 on two supports 7 are at same horizontal plane, match between two PVC boards 6, after the completion of catchmenting, 6 level closure backs of PVC board both can prevent that debris from falling into the polluted water, can eliminate the potential safety hazard again.

When the water level in the reservoir is at the high water level 12 as shown in fig. 1, the wood block 11 floats on the water surface, and no downward pull force is generated on the PVC plate 6. At the moment, the PVC plate 6 is horizontally covered on the top of the tank body under the self-weight and supporting action of the bracket 7, so that impurities such as leaves, garbage and the like can be prevented from falling into the tank to pollute the water body; the potential safety hazard of the exposed pool top is solved; meanwhile, due to the covering, the water can be prevented from overflowing from the pool wall to wash the wall and the ground after the pool is full.

When the water level in the reservoir is lower than the high water level 12, the wood block 11 generates a downward pulling force to the PVC plate 6 due to its own weight, and the PVC plate 6 is inclined toward the interior of the reservoir as the water level is lowered. When the water level continues to drop, the PVC plate 6 maintains a certain angle to collect water, the water collecting area is far larger than the occupied area of the pool body, and the water collecting efficiency is greatly improved. When the water level in the pool rises to the high water level 12, the downward pulling force of the wood block 11 disappears, and the PVC plate 6 continuously covers the top of the pool in a horizontal shape to block the water storage process, so that the protection effect is exerted.

The utility model provides a thinking and implementation method suitable for arid area agricultural irrigation's cistern, the concrete application way is many, only above the utility model discloses a preferred embodiment should point out, to this technical field's ordinary skilled person, is not deviating from the utility model discloses under the prerequisite of principle, can also make a plurality of improvements, these improvements also should be regarded as the utility model discloses a protection scope.
