Description

Technical Field

[0001] The invention belongs to the field of environmental survey, in particular to a field survey device for remediation of polluted farmland. Background Art

[0002] Polluted arable land refers to arable land that has been eroded by atmospheric acid rain or water rich in toxic and harmful substances, which has deteriorated the original physical and chemical properties of the soil and lost its production potential, resulting in harm to humans, livestock, poultry and fisheries caused by agricultural and forestry by-products on the arable land.

[0003] Specifically, toxic pollutants are discharged directly or indirectly into cultivated soil through the atmosphere, water and organisms, exceeding the environmental capacity of cultivated soil, thereby breaking the balance of the internal system of cultivated soil and causing changes in soil structure and function.

[0004] With the progress of society, more and more attention has been paid to the development and construction of new rural areas. In order to speed up the development of new rural areas and better manage polluted farmland, people have invented some equipment, including field geographical environment monitoring devices for the treatment of polluted farmland.

[0005] However, research has found that existing field survey equipment for contaminated farmland remediation has certain drawbacks when used;

[0006] The existing field survey equipment for the remediation of polluted farmland requires manual labor to carry a series of measuring instruments to the site for shooting, and to measure the approximate area of ​​the polluted farmland, the looseness of the soil, and the slope of the polluted farmland. There are many measurement items, and the relevant construction personnel need to carry a large number of instruments. In addition, the area of ​​polluted farmland is generally large, and the staff need to carry out multiple measurements, which has a high workload and low measurement accuracy, which does not meet people's usage requirements. Summary of the invention

[0007] In order to overcome the shortcomings of the prior art, an embodiment of the present application provides a field survey device for the remediation of contaminated farmland, which is based on a drone. When in use, the drone movement is used to insert a feedback column into the boundary of the contaminated farmland. The device can automatically determine the boundary position of the contaminated farmland based on the signal feedback from the locator on the feedback column, and can directly calculate the area of ​​the contaminated farmland. This measurement work does not require on-site processing by staff, and the survey is relatively convenient.

[0015] The present invention records a field survey device for the remediation of polluted farmland, which is mainly composed of an unmanned aerial vehicle. When in use, the feedback column is inserted into the boundary of the polluted farmland by the movement of the unmanned aerial vehicle. The device can automatically determine the boundary position of the polluted farmland based on the signal feedback from the locator on the feedback column, and can directly calculate the area of ​​the polluted farmland. This measurement work does not require on-site processing by staff, and the survey is relatively convenient.

The unmanned aerial vehicle keeps a constant altitude during flight. The slope can be determined according to the difference between the unmanned aerial vehicle and the ground data detected by the laser distance measuring device. In addition, the distance measurement value of the laser distance measuring device can be kept constant. A feedback column is lowered at the same height so that the feedback column is inserted into the ground.

[0042] Preferably, an audible and visual alarm is provided on the upper end surface of the feedback column, and a wireless module is provided inside the feedback column.

[0043] The present invention records a field survey device for the remediation of polluted farmland, which records a feedback column. When in use, the feedback column is inserted into the ground. During the remediation of the polluted farmland, an audible and visual alarm can be remotely activated to warn surrounding personnel and prevent them from approaching. The device is convenient to use, and the arrangement of a locator and an audible and visual alarm on the feedback column can also help staff find their position, which is convenient for the recovery of the polluted farmland after remediation.

[0089] It should be noted that the present invention is a field survey device for the remediation of polluted farmland. When in use, the surveyor remotely controls the operation of the drone body 1 so that the drone body 1 flies along the edge of the polluted farmland.

[0090] During the flight, the motor 11 is started, and the motor 11 drives the adjusting disk 12 to rotate. When the adjusting disk 12 rotates, the protrusion 14 is driven to contact the limit block 15, and the limit block 15 is pushed to move, so that the overlap area of ​​the strip opening 18 and the through opening 5 becomes larger, so that the buffer column 10 falls, and the buffer column 10 is inserted into the ground, and then the positioner sends its position signal to the operator, and the operator determines the range and area according to the data of each point;

[0091] When in use, the laser distance measuring device 8 on the drone body 1 monitors the distance from the ground. At the same time, the built-in radar on the drone can display its height in the air (compared with the height of the horizontal plane, which belongs to the prior art). During flight, the drone maintains a constant height of the horizontal plane. The slope can be determined based on the difference between the laser distance measuring device 8 and the ground data. In addition, the distance measurement value of the laser distance measuring device 8 can be kept constant. The feedback column 6 is lowered at the same height from the ground so that the feedback column 6 is inserted into the ground. The depth of the feedback column 6 inserted into the ground can be judged by the scale line to directly determine the softness of the soil, and the measurement is relatively comprehensive.

[0092] During the remediation of polluted farmland, the sound and light alarm can be remotely activated to alert surrounding personnel and prevent them from getting close, which is very convenient to use.

[0093] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
