Description

Technical Field

[0001] The present invention relates to the field of soil detection equipment, and more specifically, to a labor-saving automatic soil pollutant detection device. Background Art

[0002] Soil environmental pollution, abbreviated as soil pollution, refers to the phenomenon that pollutants generated by human activities enter the soil and accumulate to a certain extent, causing deterioration of soil quality. Soil pollution has characteristics such as complexity, persistence, wide sources, and difficulty in prevention and control. Soil pollutants can generally be divided into two categories: inorganic pollutants and organic pollutants. Inorganic pollutants mainly include acids, alkalis, heavy metals, salts, radioactive elements such as cesium and strontium compounds, and compounds containing arsenic, selenium, and fluorine. The harm of heavy metal pollution is extremely great. It is necessary to use a soil heavy metal detection device to detect heavy metals in the soil. On the one hand, it is used to detect the content of heavy metals, and on the other hand, it is used to explore the regional scope of heavy metal pollution, providing necessary information for the next step of treatment work.

[0003] During the process of soil heavy metal detection, first, the detection personnel set up detection points on the ground. The ways of setting up detection points include radial layout, strip layout, etc. The characteristic of setting up detection points is to evenly arrange multiple detection points at equal distances on one or more radial lines. Then, the detection personnel hold the soil heavy metal detection device. Next, the detection personnel squat beside the detection point at one end of a line. After that, the detection personnel press the soil heavy metal detection device against the detection point and start the detection until the detection is completed. Then, the detection personnel stand up and move along the line to the next detection point and squat down to detect the second detection point. Repeat this process until the detection work is completed. However, holding the soil heavy metal detection device manually for a long time is likely to cause hand fatigue and requires frequent breaks, resulting in a slow detection speed. Moreover, the detection personnel need to squat and stand up frequently during the detection process, which is extremely energy-consuming and also requires frequent breaks, further slowing down the detection speed. At the same time, frequent squatting and standing up are likely to cause the detection personnel to feel dizzy due to physiological factors, orthostatic hypotension, and anemia, and it takes a long time to recover, resulting in an even slower detection speed. Therefore, there is an urgent need to design a labor-saving automatic soil pollutant detection device. Summary of the Invention

[0004] 1. Technical Problems to be Solved

[0005] In view of the problems existing in the prior art during the detection of heavy metals in soil, first, the detection personnel set up detection points on the ground. The ways of setting up detection points include radial layout, strip layout, etc. The characteristic of setting up detection points is to equally space multiple detection points on one or more radial lines. Then, the detection personnel hold the soil heavy metal detection device in their hands. Next, the detection personnel squat beside the detection point at one end of a line. After that, the detection personnel press the soil heavy metal detection device against the detection point and start the detection until the detection is completed. Then, the detection personnel stand up and move along this line to the next detection point and squat down to detect the second detection point. Repeat this process until the detection work is completed. However, holding the soil heavy metal detection device manually for a long time is likely to cause hand fatigue and requires frequent breaks, resulting in a slow detection speed. Moreover, during the detection process, the detection personnel need to frequently squat down and stand up, which is extremely energy-consuming and also requires frequent breaks, further slowing down the detection speed. At the same time, the frequent squatting and standing up are likely to cause the detection personnel to feel dizzy due to physiological factors, orthostatic hypotension, and anemia, and it takes a long time to recover, leading to an even slower detection speed.

[0017] 3. Beneficial effects

[0018] Compared with the prior art, the advantages of the present invention are as follows:

[0019] 1. Through the carrying mechanism, the soil detector can be fixed on the unicycle mechanism. It is not necessary for the detector to hold the soil detector by hand. Through the unicycle mechanism, the weight of the soil detector can be borne, and the weight of the soil detector can be directly transmitted to the ground. It is not necessary for the detector to bear the weight of the soil detector by hand, which is more labor-saving and helps to increase the detection speed. At the same time, the detector can directly push the soil detector forward along the marking line through the unicycle mechanism, so that the soil detector is aligned with the next detection point. Through the landing center, the human action can be amplified and the kinetic energy can be transmitted to the landing mechanism to make the landing mechanism act. Through the landing mechanism, the carrying mechanism can be lowered, and then the soil detector can be lowered, so that the soil detector is against the ground at the detection point. At the same time, the landing mechanism can detect whether the soil detector is against the ground. When the soil detector is against the ground, the landing mechanism will generate corresponding actions and transmit the kinetic energy to the starter through the transmission seesaw mechanism to make the starter act. Through the acting starter, the soil detector can be started for detection. The detector does not need to squat down during the whole detection process, avoiding the adverse consequences caused by frequent squatting and standing up, which helps to further accelerate the detection speed and improve the practicability of the automatic soil pollutant detection device.

[0020] 2. By lifting the central part, the soil detector can be reset to prepare for the next detection work. Through the unicycle mechanism, the automatic soil pollutant detection device can be adjusted adaptively according to the user's height and usage habits, with better applicability. Through the alignment mechanism, the carrying mechanism can be flipped, and by flipping the carrying mechanism, the orientation of the soil detector can be changed to make the soil detector perpendicular to the ground, providing the necessary basic conditions for the detection work and being not restricted by the ground inclination, further increasing the applicability. When the soil detector is pressed against the ground for soil detection, the detector can adjust its posture according to its own habits while ensuring that the soil detector does not move, such as standing or squatting postures, increasing the applicability once again and improving the practicality of the automatic soil pollutant detection device.

[0046] Working principle:

[0047] First, bend down to hold the rectangular frame handle 11, then lift the rectangular frame handle 11 upward. Next, the rectangular frame handle 11 drives the U-shaped mouth part 13 through the handrail tube 12 to turn upward around the axle of the walking unicycle 14. After that, stand naturally and control the height of the rectangular frame handle 11 according to your own usage habits to achieve adaptive adjustment, making the automatic soil pollutant detection device adapt to the user's height and usage habits, with good applicability. Then, align it. Under the action of the gravity of the counterweight roller 25, the inclined arm 24 drives the alignment rotating arm 23 to turn downward around the central axis of the alignment fixed shaft 21, the alignment rotating tube 22, and the axle of the walking unicycle 14. Next, the alignment rotating arm 23 drives the carrying mechanism 6 to turn through the linkage wing 410, and the carrying mechanism 6 drives the soil detector 15 to turn. After that, the counterweight roller 25 lands on the ground. At this time, the central axis of the carrying block 61 is perpendicular to the ground where the walking unicycle 14 and the counterweight roller 25 are in contact. Then, the soil detector 15 is perpendicular to the ground. Next, apply a leftward thrust to the rectangular frame handle 11. Then, the rectangular frame handle 11 drives the walking unicycle 14 to move leftward through the handrail tube 12 and the U-shaped mouth part 13. Then, the walking unicycle 14 rolls on the ground on one side of the marking line. Next, the bottom end of the soil detector 15 aligns with a detection point. Then, apply a rightward pulling force to the guiding crossbar 32. Then, the guiding crossbar 32 moves rightward and pulls the traction line 33. Next, the traction line 33 is released from the outside of the small wire wheel 36 and drives it to rotate. After that, the small wire wheel 36 drives the linkage rod 35 to rotate. Then, the linkage rod 35 drives the large wire wheel 37 to rotate. Next, the traction rope 38 is released from the outside of the floor wire wheel 404 and winds around the outside of the large wire wheel 37. After that, the release of the traction rope 38 from the outside of the floor wire wheel 404 will drive it to rotate. Then, the floor wire wheel 404 drives the floor rotating rod 403 to rotate. Next, the floor rotating rod 403 drives the lifting line 52 to rotate. After that, the lifting line 52 is released from the inside of the winding ring groove 55 and winds around the outside of the lifting wire wheel 51. Then, the release of the lifting line 52 from the inside of the winding ring groove 55 will drive the lifting moving wheel 54 to rotate. Next, the lifting moving wheel 54 does work on the energy storage spring 57, increasing the torsional potential energy of the energy storage spring 57. After that, the floor rotating rod 403 drives the floor screw 405 to rotate. Then, the floor slide plate 406 moves downward under the action of the threaded fit between it and the floor screw 405. Next, the floor slide plate 406 drives the floor push plate 408 to move downward through the floor spring 407. After that, the floor push plate 408 drives the carrying mechanism 6 to move downward through the linkage wing 410, and the carrying block 61 slides downward relative to the alignment rotating arm 23. Then, the flipping right arm 87 slides downward inside the floor sliding hole 402. Next, the bottom end of the soil detector 15 abuts against the ground at the detection point. After that, the floor slide plate 406 continues to move downward and compresses the floor spring 407, and the floor spring 407 elastically shortens, reducing the elastic potential energy. Then, the bottom surface of the floor slide plate 406 contacts the end of the flipping right arm 87 and applies a downward pressure to it.Then, the right arm 87 is flipped, driving the left arm 86 to rotate clockwise about the pivot rod 84 through the flip disc 85. After that, the left end of the left arm 86 tilts upward, applying an upward lifting force to the starting piston 72 through the starting contact 74. Then, the starting piston 72 drives the starting ejector rod 73 to move upward and stretch the return spring 75. The return spring 75 elastically elongates, increasing its elastic potential energy. Next, the top end of the starting ejector rod 73 contacts the switch on the soil detector 15 and applies pressure to it. After that, the switch is turned on. At this time, the guiding crossbar 32 moves to the dead point position inside the guiding chute 31. Then, the soil detector 15 starts to detect the soil. After the detection is completed, the guiding crossbar 32 is released. Then, the lifting moving wheel 54 rotates under the torque of the power storage spring 57. After that, the lifting wire 52 is released from the outside of the lifting wire wheel 51 and winds into the inside of the wire winding ring groove 55. Then, the release of the lifting wire 52 from the outside of the lifting wire wheel 51 drives the floor turning rod 403 to rotate in the reverse direction. Next, the floor turning rod 403 drives the floor wire wheel 404 and the floor screw 405 to rotate in the reverse direction. After that, the traction rope 38 winds around the outside of the floor wire wheel 404, is released from the outside of the large wire wheel 37, and drives the large wire wheel 37 to reverse. Then, the large wire wheel 37 drives the small wire wheel 36 to reverse through the linkage rod 35. Next, the traction wire 33 winds around the outside of the small wire wheel 36 and pulls the guiding crossbar 32 to move leftward inside the guiding chute 31. After that, the floor slide plate 406 moves upward under the action of the threaded fit between it and the floor screw 405. Then, the floor slide plate 406 separates from the right arm 87. Next, the starting piston 72 drives the starting ejector rod 73 and the starting contact 74 to move downward under the elastic force of the return spring 75. After that, the starting ejector rod 73 separates from the switch, turning off the switch, and thus stopping the detection work of the soil detector 15. Then, the starting contact 74 applies pressure to the left arm 86. Next, the left arm 86 drives the right arm 87 to rotate counterclockwise about the pivot rod 84 through the flip disc 85 until the left arm 86 fits against the bottom surface of the inner cavity of the left gradually expanding channel 82. After that, the floor slide plate 406 pulls the floor spring 407. Then, the floor spring 407 elastically stretches, increasing its elastic potential energy. Next, the elastic force of the floor spring 407 is sufficient to drive the floor push plate 408 to move upward. After that, the floor push plate 408 drives the carrying block 61 to move upward through the linkage wing 410. Then, the carrying block 61 drives the soil detector 15 to move upward. Next, the soil detector 15 separates from the ground. After that, the guiding crossbar 32 moves leftward to the dead point position inside the guiding chute 31. At this time, the carrying mechanism 6 moves upward to the extreme position, and the top surface of the carrying block 61 is flush with the top surface of the alignment turning arm 23, realizing the reset of the soil detector 15. Then, the soil pollutant detection device is pushed forward along the marking line so that the soil detector 15 is aligned with the second detection point. Then, the above steps are repeated for the second detection. Repeat in this way until the detection work is completed.
