Description
Technical Field
The invention belongs to the field of water resource utilization and protection and agricultural non-point source pollution control, and relates to a structure of a retaining dam of a drainage channel of a paddy field, which is constructed in the drainage channel of the paddy field in a cold region and is used for retaining the returned water of the paddy field, preventing the returned water from automatically discharging into natural water, providing convenient conditions for the repeated utilization of the returned water of the farmland, relieving the non-point source pollution load of the received water and simultaneously not influencing the drainage function of the drainage channel of the paddy field.
Background
Water is the material basis for biological breeding and is the primary condition for agricultural production and ecological civilization construction. China is a country with serious shortage of water resources, and the holy work and the tasks which must be carried on the shoulder of our country are reasonably utilized and protected.
In China, the water consumption of agricultural production accounts for more than 60% of the total water consumption, but the water resource reuse rate in agricultural production is low, so that a large amount of water resource waste and agricultural non-point source pollution are caused. In this respect, the random discharge of the rice field water is particularly prominent.
The rice field water discharge refers to the rice field water discharge formed by crop irrigation in the rice agricultural production process. The rice field effluent contains residual chemical fertilizer, pesticide, heavy metal, soil particles and other pollutants, and is the main source of agricultural non-point source pollution. More than 50% of nitrogen pollution load and more than 30% of phosphorus pollution load in surface water body of China come from agricultural non-point source pollution. The surface water body is seriously polluted by agricultural non-point sources.
Before the rice enters the harvesting period, in order to raise the ground temperature and promote the rice to mature as soon as possible, a large amount of return water is discharged from the rice field, enters a ditch, is retained in a drainage main channel, and enters a surface water system along with the extrusion effect of the return water in the field soaking period of the rice field in the second year, so that the water environment of a receiving water body is polluted, a water ecosystem is damaged, and the serious waste of water resources is caused. Therefore, the strengthening of the impounding and the utilization of the rice field in the harvest period has great significance for the prevention and the treatment of agricultural non-point source pollution and the reasonable utilization of water resources. After the water is returned and discharged in the harvesting period of the rice field, if the water can be artificially accumulated in a drainage ditch of the rice field and used as the water for soaking the rice field in the next year, the water can be saved, and the water environment pollution of the water returned to the receiving water body is relieved.
Currently, the entrapment and regulation of agricultural water in paddy field ditches mainly occurs in the water intake canal systems of paddy fields, including various retaining dams and gates. For example, earth dams, stone dams, rubber dams, check gates, sluice gates and the like are mainly used for adjusting the water consumption of rice fields, are mostly permanent or semipermanent hydraulic structures, and have the defects of high construction cost, high maintenance and management strength and poor water environment friendliness. And at paddy field drainage canal, fall off water and get into paddy field drainage canal after, it is one row usually, do not have effectual retaining measure.
In high-latitude cold regions in China, after the paddy field is drained in the harvesting period, the paddy field needs to pass through a long freezing period and enters the field soaking period at the bottom of 4 months in the next year, and the daily average temperature is about 5 ℃. If effective measures are taken, the melting speed of the returned local ice bodies in the drainage channel of the rice field is delayed, a retaining dam consisting of the ice bodies is formed, the returned water is retained in the drainage channel, water sources are provided for soaking the rice field, the recycling rate of the production water of the rice field in a cold region is improved, the utilization rate of chemical fertilizers is improved, and the non-point source pollution of the returned water to the received water body is relieved. Meanwhile, the ice dam formed by the ice body does not need special maintenance measures, other foreign substances cannot be introduced into the environment, the maintenance and management are simple and convenient, and the environment friendliness is better.

The working principle of the invention is as follows:
(1) and (5) arranging the device. The invention is required to be placed in a drainage channel storing certain rice field water-returning and is arranged perpendicular to the water flow direction in the drainage channel. After one month after autumn harvest every year in cold regions, namely 11 months, after site reconnaissance, a plurality of heat-proof floating covers meeting the requirements of the ditch width are locked and fixed by fixing pins 119 according to different ditch widths of specific arrangement places, and two ends of each heat-proof floating cover are arranged on a dam of the ditch.

After winter, the internal water of the invention can be frozen together with the water in the ditch, and the invention is fixed in the frozen layer in the ditch.
(3) A trap dam is formed. After 4 months and in the middle of the cold region, the temperature gradually rises to be higher than 0 ℃ all day long, the ice in the ditch is melted, but the heat radiation and the heat conduction of the temperature are weakened because the cavity formed by connecting the head heat floating prevention cover 1, the middle heat floating prevention cover group 2 and the right heat floating prevention cover 3 forms a relatively closed space, the ice in the cavity is kept in a relatively low temperature range, the melting of the ice in the cavity is delayed, so that a retaining dam is formed, the rice field in the ditch is retained for water return, and convenience is provided for the reuse of the rice field water return in agricultural production, particularly for water for paddy field soaking.
(4) And (4) ablation of the interception dam. With the continuous rise of the air temperature, the ice in the ditch is gradually melted, the ditch can be disassembled and then folded, and the ditch can also be continuously arranged in the ditch, and the water conservancy function of the ditch is not prevented due to the self-adaptive capacity of the water level.
