Abstract
Disclosed is an energy consumption less small type automatic flood discharge and water storage dam used for river dikes or reservoir dams. The water retaining plate of the dam can automatically open and close according to the situation of the water level. When the water level of the upstream reaches the designed water level of the flood discharge of the dam, the water retaining plate automatically open to discharge flood; when the upstream water level of the dam falls to the designed closure water level of the dam, the water retaining plate can automatically close to store water. Opening or closing the water retaining plate depends on the special structure of the water retaining plate and the change of the upstream water level, and the desired power of the water retaining plate is from the self power of the water. The opening or closing of water retaining plate is an automatic repeated process. The automatic flood discharge and water storage of the utility model do not increase external power without people watching, which is the biggest characteristic of the automatic dam.
Description
Technical field
The invention belongs to the automation field of small-sized check dam.
Background technology
Development along with society, conquer nature flood and rationally use the check dam at water source also more and more of people, the intelligent control technology of its great rivers check dam is also perfect day by day, but the utilization and extention in the automatic control technology of the small-sized check dam of the little river river reservoir dam that spreads all over the country a bit lags behind, its major obstacle is, the expense that existing small-sized check dam is controlled equipment and maintenance automatically is too big, has hindered the universal process that small-sized check dam is realized automation.
Summary of the invention
The technical problem to be solved in the present invention: the no energy consumption of small-sized check dam flood discharge and retaining is controlled automatically.
The utility model solves the problems of the technologies described above with following technical scheme: the structure of the stop plank of check dam is, the above stop plank height of turning cylinder is the high twice of the following stop plank of turning cylinder, the weight sum of the weight of the above stop plank of turning cylinder and afterburning case, less than the weight of the following stop plank of turning cylinder, stop plank top is equipped with one the afterburning case that delays afterburning effect.
Use the automatic control technology of small-sized check dam flood discharge of no energy consumption of the present utility model and retaining, simple in structure, dependable performance, very practical helps the realization of the automation control of small-sized check dam.
Description of drawings
Fig. 1 is the small-sized automatic flood discharge of no energy consumption of the present utility model and the structural representation of retaining check dam.
The specific embodiment
The small-sized automatic flood discharge of no energy consumption and retaining check dam, by afterburning case 1., go up sideboard 2., turning cylinder 3., down sideboard 4., dam foundation seat 5., 6. positioning body form.1. afterburning case is one has big water inlet pipe and less weep hole is arranged, has the water storage box of time-lag action, water inlet pipe be connected to stop plank (afterburning case 1., go up sideboard 2., sideboard is 4. 3., down for turning cylinder) middle part, prevent that floating thing from entering.Turning cylinder is 3. above, and to go up sideboard 2. high be the following 4. high twice of sideboard down of turning cylinder, and turning cylinder is 3. above goes up 1. weight sum of sideboard weight 2. and afterburning case, less than sideboard weight 4. under below the turning cylinder.
After the check dam retaining, when water level was high above stop plank, water overflowed from stop plank, also gave the 1. water filling of afterburning case simultaneously, when continuing to raise, water level reaches one regularly, the water inlet 1. of afterburning case is greater than water outlet, and afterburning case 1. retaining increases, at this moment, the water gravity sum of the water pressure of last sideboard and afterburning case, greater than the following water pressure of sideboard, the stop plank upset, and be flat on the positioning body, check dam enters the flood discharge state.Below water level is reduced to turning cylinder during a certain water level, stop plank only is subjected to the self gravitation effect, go up 1. weight sum of sideboard weight 2. and afterburning case because of turning cylinder is 3. above, less than following sideboard weight 4. below the turning cylinder, stop plank turns round automatically, check dam enters the retaining state.The upset of stop plank and revolution are the processes of repetitive cycling, and rely on stop plank design feature and SEA LEVEL VARIATION state to realize entirely.
In order to simplify the structure of stop plank, can save afterburning case, go up sideboard and the high ratio of following sideboard in sideboard, the adjustment but need increase, make water level reach one regularly, stop plank can overturn and turn round automatically, improves that like this stability of stop plank is descended to some extent.
Claims (1)
1, a kind of small-sized automatic flood discharge and retaining check dam that does not have energy consumption, it is characterized in that: the small-sized automatic flood discharge of no energy consumption and the stop plank of retaining check dam structure, the above stop plank height of turning cylinder is the high twice of the following stop plank of turning cylinder, the weight sum of the weight of the above stop plank of turning cylinder and afterburning case, less than the weight of the following stop plank of turning cylinder, the afterburning case that be equipped with on stop plank top is one the water storage box that delays afterburning effect.
