Description

Technical Field

[0001] This utility model relates to the field of soil remediation technology, and in particular to a soil pollution treatment device for ecological environment restoration. Background Technology

[0002] Soil remediation is a technical measure to restore contaminated soil to its normal function. In the soil remediation industry, there are over one hundred existing technologies, with more than ten commonly used. These can be broadly categorized into physical, chemical, and biological methods. A common method in chemical remediation is to inject chemicals into the soil, where they react with harmful substances to remove them.

[0003] For example, Chinese utility model patent application number 202322427830.X discloses a deep infusion device for soil remediation agents; it includes a mobile vehicle, an installation frame, a control cylinder, a support plate, a storage tank, a crushing component, a mixing component, an infusion component, a limiting sliding rod, and a limiting sliding sleeve. This utility model can perform intermittent deep infusion of remediation agents into the soil. During soil remediation, the infusion component moves down and penetrates deep into the soil, infusing the surrounding soil with the remediation agent. This operation ensures that the remediation agent does not merely float on the soil surface but penetrates deep into the soil for rapid penetration.

[0004] The aforementioned patent lacks the function of sealing and protecting the drug distribution holes. When the infiltration cylinder moves up and down inside the soil, the drug distribution holes on the infiltration cylinder are easily blocked by the soil, affecting the subsequent injection of remediation agents. In addition, the aforementioned patent lacks the function of automatically cleaning the surface of the infiltration cylinder. After each use of the equipment, manual cleaning is required, which is time-consuming, labor-intensive, and increases the workload of the staff. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a soil pollution treatment device for ecological environment restoration.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a soil pollution treatment device for ecological environment restoration, comprising a mobile vehicle, two sets of lifting mechanisms on the top of the mobile vehicle, a moving plate between the two sets of lifting mechanisms, a deep insertion cylinder fixedly connected to the bottom of the moving plate, a plurality of drug distribution holes on the outer surface of the deep insertion cylinder, an arc-shaped guide surface on the inner surface of the drug distribution holes, a sealing mechanism for sealing and protecting the drug distribution holes inside the deep insertion cylinder, a water supply mechanism and a cleaning mechanism on the top of the mobile vehicle, a through groove on the top of the mobile vehicle corresponding to the position of the deep insertion cylinder, the water supply mechanism for supplying restoration agent into the deep insertion cylinder, and the cleaning mechanism for cleaning the outer surface of the deep insertion cylinder.

[0007] As a further description of the above technical solution:

[0008] The lifting mechanism includes a U-shaped column fixedly installed on the top of the mobile vehicle. An electric telescopic rod is fixedly connected to the top of the U-shaped column. The telescopic end of the electric telescopic rod is fixedly connected to the bottom of the mobile plate. The mobile plate is movably inserted between the two U-shaped columns. Through the setting of the lifting mechanism, the deep insertion cylinder can be driven to rise or fall, so as to move the deep insertion cylinder down to insert into the soil and move it up to exit the soil.

[0009] As a further description of the above technical solution:

[0010] The sealing mechanism includes several springs fixedly installed at the bottom of the movable plate. A piston is fixedly connected to the other end of each spring. A movable column is fixedly connected to the bottom of the piston. A fixed cylinder is fixedly connected to the outer surface of the movable column at the position corresponding to the drug delivery hole. A sealing rod is movably connected inside the fixed cylinder. A spring is fixedly connected between the fixed cylinder and the sealing rod. By setting up the sealing mechanism, soil can be prevented from entering the drug delivery hole when the deep insertion cylinder is inserted into the soil and when it is moved upward and withdrawn from the soil, thus preventing the drug delivery hole from being blocked.

[0011] As a further description of the above technical solution:

[0012] The end of the sealing rod away from the fixed cylinder is embedded in the drug distribution hole, and the sealing rod is adapted to the drug distribution hole.

[0013] As a further description of the above technical solution:

[0014] The water supply mechanism includes a water pump, which is fixedly installed on the top of the mobile vehicle. The water pump's suction end is fixedly connected to a chemical tank, and the water pump's outlet end is fixedly connected to a flexible hose. The other end of the flexible hose is fixedly connected to a deep insertion cylinder. Through the water supply mechanism, during the soil irrigation process, the water pump draws the repair agent from the chemical tank and delivers it to the internal cavity of the deep insertion cylinder through the flexible hose. When the application hole is opened, the repair agent is injected into the surrounding soil from the application hole.

[0015] As a further description of the above technical solution:

[0016] The medicine tank is fixedly installed on the top of the mobile vehicle, and a water inlet is fixedly connected to the top of the medicine tank.

[0017] As a further description of the above technical solution:

[0018] The cleaning mechanism includes a second water pump, which is fixedly installed on the top of the mobile vehicle. The pump's suction end is fixedly connected to a clean water tank, and its outlet end is fixedly connected to a water supply pipe. The other end of the water supply pipe is fixedly connected to a ring pipe, which has several spray holes arranged in a circular array. With the cleaning mechanism in place, when the deep insertion cylinder moves upward, the second water pump draws clean water from the clean water tank and delivers it to the ring pipe through the water supply pipe. The clean water is then sprayed from the spray holes onto the outer surface of the deep insertion cylinder, thus washing away the mud adhering to the outer surface of the deep insertion cylinder.

[0019] As a further description of the above technical solution:

[0020] The clean water tank is fixedly installed on the top of the mobile vehicle, and the top of the clean water tank is fixedly connected to a second water inlet.

[0021] This utility model has the following beneficial effects:

[0022] 1. Compared with existing technologies, this soil pollution treatment device for ecological environment remediation uses a piston to drive the moving column, fixed cylinder and sealing rod to move up and down, and the arc-shaped guide surface on the inner surface of the drug distribution hole guides the sealing rod, realizing the opening and sealing protection of the drug distribution hole. This avoids soil from entering the drug distribution hole when the deep insertion cylinder is inserted and moved upward to withdraw from the soil, thus effectively preventing the risk of blockage of the drug distribution hole and facilitating the smooth injection of remediation agents into the soil.

[0023] 2. Compared with existing technologies, this soil pollution treatment device for ecological environment restoration delivers clean water to the ring pipe through a water supply pipe, and finally sprays the clean water from the spray hole onto the outer surface of the deep insertion cylinder to wash away the soil attached to the outer surface of the deep insertion cylinder. This achieves automatic cleaning of the surface of the deep insertion cylinder without the need for manual cleaning by staff, saving time and effort and reducing the workload of staff.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1-5 This utility model provides a soil pollution treatment device for ecological environment restoration: it includes a mobile vehicle 1, with two sets of lifting mechanisms on the top of the mobile vehicle 1, and a moving plate 2 between the two sets of lifting mechanisms. A deep insertion cylinder 3 is fixedly connected to the bottom of the moving plate 2. Several drug distribution holes 4 are opened on the outer surface of the deep insertion cylinder 3, and an arc-shaped guide surface 5 is opened on the inner surface of the drug distribution holes 4. A sealing mechanism for sealing and protecting the drug distribution holes 4 is provided inside the deep insertion cylinder 3. A water supply mechanism and a cleaning mechanism are provided on the top of the mobile vehicle 1. A through groove 6 is opened on the top of the mobile vehicle 1 at the position corresponding to the deep insertion cylinder 3. The water supply mechanism is used to supply the restoration agent into the deep insertion cylinder 3, and the cleaning mechanism is used to clean the outer surface of the deep insertion cylinder 3.

[0033] The lifting mechanism includes a U-shaped column 7 fixedly installed on the top of the mobile vehicle 1. An electric telescopic rod 8 is fixedly connected to the top of the U-shaped column 7. The telescopic end of the electric telescopic rod 8 is fixedly connected to the bottom of the mobile plate 2, and the mobile plate 2 is movably inserted between the two U-shaped columns 7.

[0034] The sealing mechanism includes several springs 9 fixedly installed at the bottom of the movable plate 2. A piston 10 is fixedly connected between the other ends of the springs 9. A movable column 11 is fixedly connected to the bottom of the piston 10. A fixed cylinder 12 is fixedly connected to the outer surface of the movable column 11 at the position corresponding to the drug delivery hole 4. A sealing rod 13 is movably connected inside the fixed cylinder 12. A spring 14 is fixedly connected between the fixed cylinder 12 and the sealing rod 13. The end of the sealing rod 13 away from the fixed cylinder 12 is embedded in the drug delivery hole 4, and the sealing rod 13 is adapted to the drug delivery hole 4.

[0035] The piston 10 drives the moving column 11, the fixed cylinder 12 and the sealing rod 13 to move up and down, and the arc-shaped guide surface 5 on the inner surface of the drug distribution hole 4 guides the sealing rod 13, thus realizing the opening and sealing protection of the drug distribution hole 4. This avoids soil from entering the drug distribution hole 4 when the deep insertion cylinder 3 is inserted and moved upward to withdraw from the soil, thereby effectively preventing the risk of blockage of the drug distribution hole 4 and facilitating the smooth injection of the remediation agent into the soil.

[0036] The water supply mechanism includes a water pump 15, which is fixedly installed on the top of the mobile vehicle 1. The water pump 15 is fixedly connected to a medicine tank 16 at its pumping end and a hose 17 at its outlet end. The other end of the hose 17 is fixedly connected to a deep insertion cylinder 3. The medicine tank 16 is fixedly installed on the top of the mobile vehicle 1, and a water inlet 18 is fixedly connected to the top of the medicine tank 16.

[0037] The cleaning mechanism includes a second water pump 19, which is fixedly installed on the top of the mobile vehicle 1. The water pump 19 is fixedly connected to a clean water tank 20 at its pumping end and to a water supply pipe 21 at its outlet end. The other end of the water supply pipe 21 is fixedly connected to a ring pipe 22. The ring pipe 22 has several spray holes 23 arranged in a circular array. The clean water tank 20 is fixedly installed on the top of the mobile vehicle 1, and the top of the clean water tank 20 is fixedly connected to a second water inlet 24.

[0038] Clean water is delivered to the ring pipe 22 through the water supply pipe 21, and finally sprayed onto the outer surface of the deep insertion cylinder 3 through the spray hole 23 to wash away the mud attached to the outer surface of the deep insertion cylinder 3, thereby achieving automatic cleaning of the surface of the deep insertion cylinder 3 without the need for manual cleaning by staff, saving time and effort and reducing the workload of staff.

[0039] Working principle: When it is necessary to remediate contaminated soil, the staff first injects the remediation agent into the chemical tank 16 through water inlet 18, and injects clean water into the clean water tank 20 through water inlet 24.

[0040] The staff then pushed the mobile vehicle 1 to the designated position and activated the two electric telescopic rods 8, causing their telescopic ends to move down synchronously. This moved the mobile plate 2 and the deep insertion cylinder 3 down, allowing the deep insertion cylinder 3 to pass through the through groove 6 and insert into the soil until it reached the predetermined depth. During this insertion, the sealing rod 13, embedded in the application hole 4, prevented soil from entering and blocked the hole, thus avoiding the risk of blockage. This facilitated the subsequent injection of the remediation agent into the soil. At this point, the electric telescopic rods 8 were turned off and the water pump 15 was activated. The pump 15 drew the remediation agent from the chemical tank 16. The repair agent is delivered to the internal cavity of the deep insertion cylinder 3 through the hose 17. The internal pressure of the deep insertion cylinder 3 increases, pushing the piston 10 to move the moving column 11 towards the moving plate 2. The spring 9 is compressed to store energy. When the moving column 11 moves, it drives the fixed cylinder 12 and the sealing rod 13 to move. The sealing rod 13 is guided by the arc-shaped guide surface 5 on the inner surface of the drug distribution hole 4, so that the sealing rod 13 can smoothly exit the drug distribution hole 4. At this time, the drug distribution hole 4 is in the open state, so the repair agent in the deep insertion cylinder 3 is injected into the surrounding soil from the drug distribution hole 4. During the process of the sealing rod 13 moving upward and exiting the drug distribution hole 4, the sealing rod 13 abuts against the inner wall of the deep insertion cylinder 3, squeezing the spring 14 to compress it and store energy.

[0041] After the injection is completed, the water pump 15 is turned off. The piston 10 and the moving column 11 are pushed downward by the elastic force of the spring 9. At the same time, when the sealing rod 13 moves to the position opposite to the drug distribution hole 4, the sealing rod 13 is pushed into the drug distribution hole 4 by the elastic force of the spring 2 14, sealing and protecting the drug distribution hole 4. This prevents soil from entering the drug distribution hole 4 and causing blockage of the drug distribution hole 4 during the process of the deep insertion cylinder 3 moving upward and exiting the soil.

[0042] Then, the two electric telescopic rods 8 and the second water pump 19 are activated. The two electric telescopic rods 8 drive the moving plate 2 and the deep insertion cylinder 3 to move upward through the through groove 6. At the same time, the pumping end of the second water pump 19 draws clean water from the clean water tank 20 and delivers the clean water to the ring pipe 22 through the water supply pipe 21. Finally, the clean water is sprayed from the spray hole 23 onto the outer surface of the deep insertion cylinder 3 to wash away the mud attached to the outer surface of the deep insertion cylinder 3, realizing automatic cleaning of the surface of the deep insertion cylinder 3 without the need for manual cleaning by staff, saving time and effort and reducing the workload of staff.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
