Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of soil remediation equipment, and particularly relates to a soil remediation device for ecological environment management and a use method thereof. BACKGROUND

[0002] Soil remediation in ecological environment management is a process of restoring the ecological function of contaminated or degraded soil. Soil may be contaminated by heavy metals, organic matter, pesticide residues and other pollutants due to industrial pollution, misuse of agricultural chemicals, landfill and other factors. Remediation methods include physical remediation, such as soil replacement and heat treatment to separate pollutants, chemical remediation, which uses chemical reagents to react with pollutants to fix and degrade them, and biological remediation, which purifies soil through plant absorption and microbial decomposition. It is crucial for protecting agricultural product safety and maintaining ecological balance. For example, patent authorization announcement No. CN117443924B discloses a soil remediation device for ecological environment management.

[0003] Currently, when soil is remediated by a soil remediation device and a chemical remediation agent, the drilling structure of the soil remediation device is inserted into the ground to form a hole, then the soil remediation device delivers the chemical soil remediation agent into the hole, and finally the chemical soil remediation agent in the hole is dispersed into the soil around the hole for remediation. However, this remediation process is affected by soil density, resulting in a small dispersion range of the chemical soil remediation agent, which causes a small soil remediation range. Therefore, intensive drilling is required to inject the chemical soil remediation agent, which not only affects the convenience and efficiency of soil remediation, but also easily causes the chemical soil remediation agent content in the local soil to be too high, which easily causes waste of the chemical soil remediation agent, increases the cost of soil remediation, and the high concentration of the chemical soil remediation agent also easily affects the survival rate of surface plants. If the surface plants wither, it will further affect the effect of soil remediation and the success rate of ecological environment management.

[0018] A method for using a soil remediation device for ecological environment management, the method comprising the following steps:

[0019] Step S1, first inject the prepared chemical soil remediation agent into the remediation agent box for standby, then connect the moving vehicle to the tractor through the traction ring, and move the moving vehicle to the position where soil remediation is needed through the tractor;

[0020] Step S2, start the air pump to increase the gas pressure in the gas storage tank, then use the gas pressure, the sealing ring and the ferrous moving strip to move the lifting cylinder and the sharp-tipped insertion tube downward, and make the sharp-tipped insertion tube inserted into the surface soil, and the liquid injection hole is located inside the surface soil;

[0021] Step S3, after the sharp-tipped insertion tube is inserted into the ground, the two electrified rods of the touch pressure mechanism are conducted by the conductive block and send a trigger electric signal to the PLC controller, the PLC controller records the gas pressure value P1 of the gas storage tank detected by the gas pressure sensor at this time according to the trigger electric signal, at the same time, the PLC controller also controls the liquid supply mechanism to deliver a certain amount of chemical soil remediation agent to the gas storage tank, and the limiting electromagnetic ring is electrified to tightly adsorb the ferrous moving strip moved to the position;

[0023] Step S5, after the chemical soil remediation machine is sprayed, the PLC controller controls the energization of the first reversing electromagnetic valve and the second reversing electromagnetic valve, so that the air supply mechanism changes from air charging to air extraction from the gas tank, and the air pressure sensor monitors the air pressure in the gas tank in real time during the air extraction process, by comparing the air pressure value of the air pressure sensor at this time with the P1 value, if the air pressure value at this time is less than half of the P1 value, it indicates that the soil at the sharp head insertion pipe is too dense, and the chemical soil remediation agent cannot be uniformly distributed in a large range in the loose soil, otherwise, if the air pressure value at this time is similar to the P1 value, it indicates that the soil at the sharp head insertion pipe is loose and breathable, and the chemical soil remediation agent can be uniformly distributed in a large range in the loose soil, and secondary spraying of the chemical soil remediation agent is needed for soil remediation.

[0024] Step S6, during the insertion of the sharp head insertion pipe into the soil in step S2, if the soil inside contains stones that hinder, at this time, because the sharp head insertion pipe cannot be moved downward, the gas tank is continuously filled with air by the air pump, so that the air pressure in the gas tank increases sharply, and when the air pressure in the gas tank detected by the air pressure sensor reaches the high pressure threshold value preset by the PLC controller, the PLC controller controls the alarm to flash and alarm in time, reminding the worker to remove the stone obstruction in time, or by moving the vehicle to change the insertion position of the sharp head insertion pipe, and then the soil remediation work is restarted.

[0027] 2. Through the set of gas supply mechanism, pressure sensor and sharp head insertion tube, after the chemical soil remediation agent is sprayed, the PLC controller controls the energization of the first reversing electromagnetic valve and the second reversing electromagnetic valve, so that the gas supply mechanism changes from gas charging to gas extraction from the gas storage tank, the gas pressure sensor monitors the gas pressure in the gas storage tank in real time during the gas extraction process, by comparing the gas pressure value at this time with the P1 value, if the gas pressure value at this time is less than half of the P1 value, it indicates that the soil at the sharp head insertion tube is too dense, and the chemical soil remediation agent cannot be distributed in a large range and uniformly in the loosened soil, on the contrary, if the gas pressure value at this time is similar to the P1 value, it indicates that the soil at the sharp head insertion tube is loose and permeable, and the chemical soil remediation agent can be distributed in a large range and uniformly in the loosened soil, and secondary spraying of the chemical soil remediation agent is needed for soil remediation, this mechanism makes the soil remediation device have the function of soil density detection, and feedbacks the effect of soil remediation through the density detection, further improves the convenience and efficiency of soil remediation, and improves the success rate of ecological environment governance.

[0028] 3. By setting the first reversing solenoid valve, the second reversing solenoid valve, the alarm and the pressure sensor, the sharp cannula is inserted into the soil, if the soil contains stones inside, at this time, the sharp cannula cannot be moved down, and the air tank is continuously filled with air by the air pump, so that the air pressure in the air tank increases sharply, at this time, when the air pressure sensor detects that the air pressure in the air tank reaches the high pressure threshold preset by the PLC controller, the PLC controller controls the alarm to flash and alarm in time, reminding the staff to remove the stone obstruction in time, or by moving the car to replace the sharp cannula insertion position, and re-perform the soil repair work, ensure that the sharp cannula can be smoothly inserted into the soil for repair work, the mechanism makes the soil repair device have the function of soil stone obstruction alarm, improve the reliability of the soil repair device.

[0044] The operation principle of the present application is described as follows: when the ecological environment management process needs to repair the soil, first, the chemical soil repair agent is injected into the repair agent box 2 for standby, at the same time, the mobile vehicle 1 is connected to the towing vehicle through the traction ring 24, and then the mobile vehicle 1 is moved to the position where the soil needs to be repaired through the towing vehicle;

[0045] Then the PLC controller 18 controls the air pump 71 to start, the air pump 71 sucks air through the second reversing electromagnetic valve 74, the air is injected into the air storage tank 4 through the first reversing electromagnetic valve 72, the first conduit 73 and the second conduit 75, the air in the air storage tank 4 pushes the sealing ring 15 and the iron moving strip 14 to move downward, the iron moving strip 14 moves downward to drive the lifting cylinder 5 to move downward, the lifting cylinder 5 moves downward to push the sharp head insertion pipe 12 to insert into the ground surface, and the liquid injection hole 13 is located in the inside of the ground surface soil, at the same time, the iron moving strip 14 moves downward to extrude the second spring 9, so that the second spring 9 is compressed to store energy;

[0046] With the depth of the pointed cannula 12 inserted into the ground, the distance between the block 61 and the ground is shorter, and finally when the pointed cannula 12 is completely inserted into the ground, the block 61 is in contact with the ground and is pressed by the ground, and at the same time, the T-shaped insulating rod 63 is pressed upward by the ground, thereby pushing the conductive block 65 into contact with the two conductive rods 67, connecting the circuit of the two conductive rods 67, and sending a trigger electrical signal to the PLC controller 18, and the PLC controller 18 records the air pressure value P1 detected by the air pressure sensor 76 at this time, and at the same time, the PLC controller 18 also controls the water pump 31, the limiting electromagnetic ring 21 and the control electromagnetic valve 33 to start, and the water pump 31 sends the chemical soil repair agent in the repair agent tank 2 to the storage tank 4 through the water pipe 32, the control electromagnetic valve 33 and the electronic flow meter 34, and the electronic flow meter 34 monitors the supply amount of the chemical soil repair agent in real time, and converts the supply amount of the chemical soil repair agent into a supply amount electrical signal and sends it to the PLC controller 18, and if the supply amount of the chemical soil repair agent recorded by the electronic flow meter 34 reaches the repair agent supply threshold set by the PLC controller 18, the PLC controller 18 controls the water pump 31 and the control electromagnetic valve 33 to close, and the air pressure sensor 76 can detect the air pressure in the storage tank 4 in real time and convert the air pressure value into an air pressure electrical signal and send it to the PLC controller 18, and the limiting electromagnetic ring 21 generates a strong magnetic attraction after being energized, and can tightly attract the iron moving strip 14 in contact with each other, thereby ensuring the position of the pointed cannula 12 inserted into the ground is stable and reliable;

[0047] When the PLC controller 18 records the P1 data of the air pressure sensor 76, the PLC controller 18 also continues to control the air pump 71 to inject air into the storage tank 4, and increase the air pressure value of the storage tank 4, and when the air pressure value of the storage tank 4 reaches the air explosion pressure threshold set by the PLC controller 18, the PLC controller 18 controls the air pump 71 to close, and the normally closed electromagnetic valve 10 is energized to open, and due to the high pressure environment of the storage tank 4, the compressed air in the storage tank 4 carries the chemical soil repair agent to quickly pass through the lifting cylinder 5, the pointed cannula 12 and the liquid injection hole 13, and is sprayed out, and the gas explosion phenomenon occurs at the liquid injection hole 13, and the airflow generated by the gas explosion not only can loosen the soil, but also can convert the chemical soil repair agent into water mist, and the water mist of the chemical soil repair agent can be distributed in a larger range and more uniformly under the assistance of the gas explosion impact and loosened soil, thereby improving the repair range of the chemical soil repair agent, and without the need for dense drilling to arrange the chemical soil repair agent, saving time and effort, and avoiding the situation of increasing repair cost due to waste of chemical repair agent, in addition, the loosened soil can also increase the air permeability of the soil, which is more suitable for the root development of the surface plant, expands the distribution range of the root system of the surface plant, and uses the surface plant to speed up the soil repair, thereby further improving the effect of soil repair;

[0048] With the decrease of the amount of air inside the gas tank 4, the air pressure inside the gas tank 4 also decreases, making the exhaust speed of the gas tank 4 slower in the later stage of exhaust, especially when the air pressure sensor 76 detects that the air pressure of the gas tank 4 reaches the P1 value again, the PLC controller 18 controls the first reversing solenoid valve 72 and the second reversing solenoid valve 74 to be energized, thereby changing the air guide direction of the first reversing solenoid valve 72 and the second reversing solenoid valve 74, so that the air pump 71 changes from charging the gas tank 4 to exhausting, the air pump 71 exhausts through the second conduit 75 and the second reversing solenoid valve 74, and exhausts through the air outlet of the first reversing solenoid valve 72, at this time the gas tank 4 absorbs air from the soil through the lifting cylinder 5, the pointed tube 12 and the liquid injection hole 13 to supplement the P1 air pressure value, which indicates that the chemical soil remediation agent can be uniformly distributed in the loose soil, at this time if the soil is not loose, the soil is too dense, and the gas tank 4 cannot get enough air supplement, so that the air pressure in the gas tank 4 is sucked by the air pump 71 and decreases, if the air pressure sensor 76 detects that the air pressure value of the gas tank 4 decreases to half of the P1 value, the PLC controller 18 controls the alarm 17 to issue a reminder according to the air pressure electric signal sent by the air pressure sensor 76 at this time, which indicates that the chemical soil remediation agent cannot be uniformly distributed in the loose soil, so that the soil remediation device is controlled by the worker to carry out secondary soil remediation, and in the secondary remediation process, the supply amount of the chemical soil remediation agent delivered to the gas tank 4 is half of the supply amount of the chemical soil remediation agent in the primary soil remediation, which can avoid the situation that the content of the chemical soil remediation agent is too high in the local soil remediation position, if the soil is loose at this time, the gas tank 4 can get enough air compensation, and the air pressure in the gas tank 4 can be maintained around the P1 value, the PLC controller 18 does not control the alarm 17 to alarm, at the same time, the PLC controller 18 controls the limit electromagnetic ring 21, the air pump 71, the first reversing solenoid valve 72 and the second reversing solenoid valve 74 to be de-energized and stop working, at this time the ferrous moving strip 14 loses the magnetic attraction of the limit electromagnetic ring 21, and moves up under the action of the restoring force of the compressed second spring 9, and drives the lifting cylinder 5 and the pointed tube 12 to move up, so that the pointed tube 12 is separated from the soil, finally the soil remediation device is moved to the next soil remediation position by the moving vehicle 1 to repeat the above remediation steps, the mechanism effectively improves the range and uniformity of the distribution of the chemical soil remediation agent during soil remediation by using gas explosion, and does not need to densely drill holes to arrange the chemical soil remediation agent, which saves time and effort, not only can improve the convenience and efficiency of soil remediation, but also can avoid the situation that the content of the chemical soil remediation agent is too high in the local soil, thereby reducing the cost of soil remediation, and the process of soil remediation can also improve the air permeability of the soil, and promote the root development of the surface plants, expand the distribution range of the root system of the surface plants, use the surface plants to speed up the soil remediation, effectively improve the effect of soil remediation, and can improve the success rate of ecological environment governance.

[0049] In addition, when the pointed insertion pipe 12 encounters a stone block in the soil during insertion into the soil, the pointed insertion pipe 12 cannot be lowered, and the air tank 4 is continuously filled with air by the air pump 71, so that the air pressure in the air tank 4 increases rapidly. When the air pressure sensor 76 detects that the air pressure in the air tank 4 reaches the high pressure threshold value preset by the PLC controller 18, the PLC controller 18 controls the alarm 17 to flash and alarm in time, reminding the staff to remove the stone block in time, or to replace the insertion position of the pointed insertion pipe 12 by moving the vehicle 1, and to re-perform soil repair work, so that the pointed insertion pipe 12 can be smoothly inserted into the soil for repair work. The mechanism enables the soil repair device to have the function of alarm for the stone block in the soil, and improves the reliability of the soil repair device.

[0050] The above description is only the preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.

Step S4, while the PLC controller (18) records the P1 data of the air pressure sensor (76), the PLC controller (18) also continues to control the air supply mechanism (7) to continue to increase the air pressure of the gas tank (4), when the air pressure value of the gas tank (4) reaches the air explosion air pressure threshold preset by the PLC controller (18), the PLC controller (18) controls the air pump (71) to close, and the normally closed electromagnetic valve (10) is energized to open. Due to the high pressure environment of the gas tank (4), the compressed air in the gas tank (4) will carry the chemical soil remediation agent to quickly pass through the lifting cylinder (5), the sharp tube (12) and the liquid injection hole (13) and be sprayed out, and the gas explosion phenomenon occurs at the liquid injection hole (13). The gas explosion process can carry the chemical soil remediation agent to be uniformly distributed in a large range of soil; Step S5, after the chemical soil remediation machine is sprayed, the PLC controller (18) controls the energization of the first reversing electromagnetic valve (72) and the second reversing electromagnetic valve (74), so that the air supply mechanism (7) changes from inflation to air extraction from the gas tank (4). The air pressure sensor (76) monitors the air pressure in the gas tank (4) in real time. By comparing the air pressure value of the air pressure sensor (76) at this time with the P1 value, if the air pressure value at this time is less than half of the P1 value, it indicates that the soil at the sharp tube (12) is too dense, and the chemical soil remediation agent cannot be uniformly distributed in a large range of loose soil. On the contrary, if the air pressure value at this time is similar to the P1 value, it indicates that the soil at the sharp tube (12) is loose and breathable, and the chemical soil remediation agent can be uniformly distributed in a large range of loose soil. At the same time, secondary spraying of the chemical soil remediation agent is needed for soil remediation; Step S6, during the insertion of the sharp tube (12) into the soil in step S2, if the soil inside contains stones that hinder, at this time, because the sharp tube (12) cannot be moved downward, the gas tank (4) is continuously filled with air by the air pump (71), so that the air pressure in the gas tank (4) increases rapidly. When the air pressure in the gas tank (4) detected by the air pressure sensor (76) reaches the high pressure threshold preset by the PLC controller (18), the PLC controller (18) controls the alarm (17) to flash and alarm in time, reminding the staff to remove the stone obstruction in time, or by moving the vehicle (1) to change the insertion position of the sharp tube (12), and then perform soil remediation work again.
