Description

Automatic farmland water level regulating and controlling device Technical Field The invention relates to the technical field of planting management, in particular to an automatic farmland water level regulating and controlling device. Background The rice stalks are vertical and 0.5-1.5 m high, leaf sheaths are loose, and the base parts at two sides are downwards extended to form leaf sheath edges. Cone inflorescences are loose, small spikes are rectangular, two sides of the small spikes are flattened, the small spikes contain 3 flowers, the lemma of the amphiprotic small flowers is always fine, the small spikes have miscanthus or no miscanthus, 6 stamens are used as one of important food crops for human beings, and the cultivation and eating histories are quite long. The rice is in the water demand of the existence of three stages of planting, growing and maturing all different degrees, and more common, basically, all can keep certain water level in the paddy field in order to satisfy the growth demand in each cycle of rice, but because the rice is comparatively harsh needs water growth habit, also brought very big work load for peasant and grower. Generally speaking, the water level in the paddy field is regulated and controlled by the grower through pumping water and ditching drainage (but because the paddy is planted outdoors, outdoor conditions are various, pumping water or ditching drainage is complicated through a water pump), along with the development of agriculture in China, a part of farmland water level monitoring devices are generated, but the traditional farmland water level monitoring devices can only automatically supplement water or automatically drain water and can not self-adaptively supplement water and drain water at the same time, so that the dynamic balance between water supply and drainage can not be realized, the capacity of adapting to farmland water level and natural conditions is poor, the grower is still required to frequently regulate and control manually as required, the water level can not be regulated and controlled flexibly according to the growth requirement of the paddy, and the adaptability is poor. In addition, the original purpose of deriving and developing the automatic water supply and drainage technology is to reduce manual operation and work load, a grower does not need to frequently observe the operation on site, but the existing farmland drainage is mainly due to the fact that the farmland belongs to natural environments and contains more impurities, when the paddy field water is discharged through a pipeline, the impurities in the water are collected at a water outlet filter screen and are difficult to dissipate, and when the paddy field water is seriously discharged through the pipeline, the filter screen is blocked, so that the water cannot be effectively drained, only manual cleaning is needed, time and labor are wasted, and the original purpose of the automatic water supply and drainage technology is overcome from a certain angle. Aiming at the problems, the invention provides an automatic farmland water level regulating and controlling device capable of preventing water discharge from being blocked, which can effectively solve the problem that a drain pipe is blocked and needs to be cleaned manually frequently while realizing dynamic balance of water supply and drainage. Disclosure of Invention The technical scheme of the invention aims at solving the technical problem that the prior art is too single, provides a solution which is obviously different from the prior art, and particularly aims to provide an automatic farmland water level regulating and controlling device, so as to solve the problems that the prior farmland water level monitoring device only can automatically supplement water or automatically drain water, can not simultaneously realize self-adaptive water supplement and drain, simply can not realize dynamic balance between water supply and drain, has poor capability of adapting to farmland water level and natural conditions, still needs frequent manual regulation and control by a planter according to needs, can not accurately flexibly regulate and control water level according to the growth needs of rice, and has poor adaptability. The automatic farmland water level regulating and controlling device comprises a seat plate, wherein a limit column is fixedly arranged on the upper surface of the seat plate, a lifting sliding block is arranged in the limit column in a sliding manner, one side of the lifting sliding block is connected with a balance regulating mechanism, the other side of the lifting sliding block is fixedly connected with a telescopic rod, a water pump is fixedly arranged in a groove of the seat plate, the upper surface of the seat plate is fixedly connected with a solar panel which is arranged in an eave shape through a connecting plate and the limit column, two ends of the water pump are respectively provided with a water inlet
