s2: if rainy weather is met, accumulated water is formed in the soil pit where the frequency resonance collector 1 is located, and at the moment, the plurality of electric telescopic rods 3 are controlled to start and synchronously stretch through the switch 11;
s3: the electric telescopic rod 3 drives the frequency resonance collector 1 to move upwards through the supporting arm 2, and the height of the frequency resonance collector 1 is adjusted, so that the frequency resonance collector 1 is separated from accumulated water at the bottom of a soil pit.
Working principle: when the frequency resonance collector 1 is installed, the plurality of electric telescopic rods 3 are embedded in soil around a soil pit, if rainy weather is met, accumulated water is formed in the soil pit where the frequency resonance collector 1 is located, at the moment, the plurality of electric telescopic rods 3 are controlled by the switch 11 to start and synchronously stretch, the frequency resonance collector 1 is driven to move upwards by the support arm 2, the height of the frequency resonance collector 1 is adjusted, so that the frequency resonance collector 1 is separated from the accumulated water at the bottom of the soil pit, the problem that sealing elements are corroded and fail due to long-time soaking of the frequency resonance collector 1 is prevented, and the service life of survey equipment is prolonged; after ponding is formed in the soil pit, water enters the protective shell 5 through the through groove 6, then enters the sleeve 8 through the side groove 9, the telescopic block 10 expands and stretches after absorbing water, then the switch 11 is extruded and the electric telescopic rod 3 is started, the structure can automatically detect the ponding, the height of the frequency resonance collector 1 is automatically adjusted when the ponding is formed, the automation degree of the device is further improved, the telescopic block 10 is limited through the sleeve 8, the telescopic block 10 can be limited to expand laterally, then the telescopic block 10 expands and extrudes the switch 11 sufficiently, after the telescopic block 10 is gradually dried, the telescopic block 10 contracts and does not extrude the switch 11 any more, and at the moment, the electric telescopic rod 3 contracts and the frequency resonance collector 1 is put into the soil pit again, so that seismic data are collected; when the frequency resonance collector 1 moves upwards and is separated from the bottom of the soil pit, the corrugated pipe 13 stretches downwards under the action of dead weight, and the switch 11 starts the water pump 12 at the moment, so that accumulated water in the soil pit is pumped outwards through the corrugated pipe 13 and the outer extending pipe 14, the drainage of the accumulated water is accelerated, and the accumulated water can not contact with the accumulated water after the subsequent frequency resonance collector 1 descends, so that the device can work smoothly; the filter screen is arranged to filter the mud blocks, so that the problem of blockage or damage caused by the suction of the mud blocks by the water pump 12 can be avoided, the floating ring 15 can always float on the water surface, and the suction pipe 16 is inserted into the accumulated water at the water surface, so that the accumulated water at the water surface can be always sucked, the suction pipe 16 is prevented from directly extending into the bottom of the soil pit, and the problem of blocking the suction pipe 16 by soil at the bottom of the soil pit is further caused, so that the efficiency of sucking the accumulated water is improved; when accumulated water is gradually formed in the soil pit, the floating ring 15 moves upwards under the buoyancy of the accumulated water and enters the inside of the protective shell 5 through the through groove 6, and in the process, the bristles 17 can clean the surface of the floating ring 15, so that the problem that the floating ring 15 floats difficultly due to the fact that more and more soil is adhered to the surface of the floating ring 15 is prevented; the expansion block 10 drives the poking plate 18 to slide in the side groove 9 in the expansion and extension process, so that the poking plate 18 extrudes the elastic strip 20 and bends the elastic strip, after the poking plate 18 is separated from the elastic strip 20, the elastic strip 20 swings back rapidly and continuously shakes for a certain time, and then the elastic ring 19 drives the plurality of bristles 17 to shake, so that soil on the surfaces of the bristles 17 automatically drops off, self-cleaning of the bristles 17 is realized, and after the follow-up frequency resonance collector 1 moves upwards and breaks away from the bottom of a soil pit, the floating ring 15 breaks away from the protective shell 5 downwards through the through groove 6, so that secondary pollution of the bristles 17 to the floating ring 15 can be prevented; by arranging a plurality of elastic strips 20, the poking sheets 18 sequentially press the elastic strips 20 and shake the elastic strips, so that the shake time of the bristles 17 can be prolonged, and the cleaning effect of the bristles 17 is further improved; when the water flow passes through the inside of the floating ring 15, the fan blade 22 is pushed to rotate, when the fan blade 22 and the magnetic block 24 are close to each other, the magnetic block 24 is driven to move towards the floating ring 15 by magnetic attraction, when the fan blade 22 and the magnetic block 24 are gradually far away, the magnetic block 24 is reset and far away from the floating ring 15, and in the process, the magnetic block 24 can drive the flexible film 23 to continuously undulate and move, so that the soil is further prevented from being adhered to the side surface of the floating ring 15; the water guide strip 28 can guide the water at the lower side of the floating ring 15 into the water storage block 26, when the fan blade 22 attracts the magnetic block 24, the magnetic block 24 drives the flexible membrane 23 to move towards the floating ring 15 and squeeze the water storage block 26, the water in the water storage block 26 is squeezed out, and the squeezed part of water flows out through the guide hole 27 to wash the outer side surface of the flexible membrane 23, so that the soil is further promoted to separate from the surface of the flexible membrane 23.
