Abstract
The utility model discloses a self-adjusting gate which comprises a bottom shaft (1) and a gate (2) connected with the bottom shaft. The self-adjusting gate also comprises a cable (3) and a counter weight (4), wherein a pulley block (5) is arranged between the gate and a gate pier; and the counter weight (4) is wound on the pulley block (5) through the cable. By adopting the self-adjusting gate disclosed by the utility model, the counter weight pulls the gate through the pulley block; when the water level drops and water flow is reduced, the gate is pulled up and even closed under the action of the counter weight so that the water in the reservoir is kept at a certain water level; when the water level goes up due to much water in the reservoir, the thrust of water against the gate is increased to push the gate open; the counter weight is used for balancing the opening angle and speed of the gate; and the weight of the counter weight can be set according to the field need, and the open state of the gate is automatically controlled according to the height of the water level and the magnitude of the water flow. The self-adjusting gate is simple in structure and convenient to maintain.
Description
Technical field
The utility model relates to a kind of water conservancy equipment, relates in particular to a kind of self-regulation gate.
Background technology
Gate is an indispensable equipment in the water resources and hydropower construction.Gate plays important role in the flood discharge retaining.Gate mainly contains turnover plate type and hanging at present.Hanging gate and flap gate generally adopt electric power or manpower to drive, the size of the State Control folding of adjustment gate, the size of controlled water flow.There is potential safety hazard in electric power control, and manpower control labour intensity is big.More particularly be used to make the turnover plate type gate of waterfall view,, need the angle of frequent regulating gate, often adopt the Artificial Control operation in order to produce reasonable view, very inconvenient.
Summary of the invention
Goal of the invention: the purpose of the utility model is the deficiency to prior art, provide a kind of can be according to the size of the height of water level, the current self-regulation gate of regulating gate opening automatically.
Technical scheme: in order to realize the foregoing invention purpose, the technical scheme that the utility model adopted is:
A kind of self-regulation gate comprises lower shaft and the gate that is connected with lower shaft, also comprises hawser and balancing weight, between described gate and gate pier, is provided with assembly pulley, and described balancing weight is wound in assembly pulley through hawser.
Described assembly pulley comprises that the movable pulley that is arranged on the gate gets fixed pulley with being arranged on the gate pier.
Described balancing weight is provided with container.
Described hawser is a wirerope.
Beneficial effect: the utility model compared with prior art, its beneficial effect is:
1, balancing weight is worked as drawdown, gate pull-up even closure under the effect of balancing weight when current diminish through assembly pulley tractive gate; Guarantee that water is at certain water level in the storehouse, the more water level of retaining goes up in the storehouse, and water becomes big to the thrust of gate; Promote gate opening, balancing weight is used for angle and the speed that balance gate is opened, and balancing weight can be provided with weight according to on-the-spot needs; According to the size of the height of water level, the current state opened of regulating gate automatically, simple in structure, need not adopt power equipment or automaton; Low cost of manufacture, use cost is low, is convenient to safeguard;
2, wheels are changed in employing, can change the direction of draw of hawser, and reduce the quality of balancing weight;
3, balancing weight has the container of certain volume, thereby can in container, put into the quality that water is regulated balancing weight, thus the critical unlatching water level of regulating gate, and draw materials in the scene, convenient and practical;
4, hawser adopts wirerope, and mechanical strength is good.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, through a most preferred embodiment, the utility model technical scheme is elaborated, but the protection domain of the utility model is not limited to said embodiment.
As shown in Figure 1, a kind of self-regulation gate comprises lower shaft 1 and the gate that is connected with lower shaft 2; Also comprise hawser 3 and balancing weight 4, between described gate and gate pier, be provided with assembly pulley 5, described balancing weight 4 is wound in assembly pulley 5 through hawser; Described assembly pulley comprises that the movable pulley 51 that is arranged on the gate gets fixed pulley 52 with being arranged on the gate pier; Described balancing weight is provided with container, thereby can in container, put into the quality that water is regulated balancing weight, thus the critical unlatching water level of regulating gate; Draw materials in the scene, convenient and practical hawser is a wirerope.
Claims (4)
1. self-regulation gate; It is characterized in that: comprise lower shaft (1) and the gate that is connected with lower shaft (2); Also comprise hawser (3) and balancing weight (4), between described gate and gate pier, be provided with assembly pulley (5), described balancing weight (4) is wound in assembly pulley (5) through hawser.
