Description

Technical Field

[0001] The utility model relates to the field of soil remediation, in particular to soil remediation equipment for environmental engineering. Background Art

[0002] Soil remediation is a complex environmental engineering task. It aims to effectively improve the polluted soil environment and restore its ecological function and production potential through a series of technical means. This process combines physical, chemical and biological methods to transfer, absorb, degrade and transform pollutants in the soil, thereby reducing their concentration to an acceptable safety level, or converting toxic and harmful pollutants into substances that are harmless to the environment and organisms.

[0003] After searching, Chinese patent announcement number: CN220371906U discloses a soil remediation equipment for environmental engineering, which includes a frame, a lifting support component including a telescopic motor installed on the top of the support, a connecting seat is connected to the top of the movable end of the telescopic motor, and a bracket is connected between the two connecting seats. The drilling and feeding component includes a driving motor installed on the top of the bracket, the output end of the driving motor is connected to a conical tooth, and the outer side of the threaded drill rod is connected to a driven tooth that cooperates with the conical tooth transmission. The threaded drill rod is provided with a plurality of through holes connected to the inner cavity of the threaded drill rod. The telescopic motor drives the height position of the drilling and feeding component to change when it works. At the same time, the driving motor works to drive the threaded drill rod connected to the driven tooth to rotate, and the telescopic motor drives the threaded drill rod up and down to drill a hole in the land to be repaired. The repair fluid is transported to the threaded drill rod through the connecting pipe, and then injected into the land to be repaired through the through hole, so that the repair fluid penetrates into the deeper position of the land.

[0004] In the above technology, although the driving motor is realized to drive the threaded drill rod connected to the driven gear to rotate, the telescopic motor drives the threaded drill rod up and down, and the land to be repaired is drilled, the repair fluid is transported to the threaded drill rod through the connecting pipe, and then injected into the land to be repaired through the through hole, so that the repair fluid penetrates into the deeper position of the land. However, when the threaded drill rod is operated deep underground, its inner cavity is connected to the through hole, and the through hole lacks necessary protective measures, which may cause soil to invade into it during the downward rotation process. Once the through hole is blocked by soil, it will not only affect the normal operation of the drill rod, but also may have a serious negative impact on the efficiency of the soil remediation project, reducing the overall work progress and effect. Therefore, a soil remediation equipment for environmental engineering is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a soil remediation device for environmental engineering, comprising a frame 1, which is the main body of the device and is used to support and fix other components. A moving plate 2 is slidably connected to the upper side of the top of the frame 1, and the moving plate 2 is used to support the rotating hole assembly. A telescopic motor 3 is fixedly connected to the top of the moving plate 2, and the moving plate 2 is driven to move up and down by two groups of telescopic motors 3. The output shaft of the telescopic motor 3 penetrates and slides on the inner wall of the moving plate 2, and the bottom end of the output shaft of the telescopic motor 3 is fixedly connected to the top of the frame 1. A driving motor 4 is fixedly connected to the top of the moving plate 2. The driving motor 4 serves as a power source for the rotating hole assembly. The inner wall of the moving plate 2 is provided with a rotating hole assembly, and the rotating hole assembly comprises a gear 1 51, and the inner wall of the gear 1 51 is fixedly connected to the outer wall of the bottom end of the output shaft of the driving motor 4. A gear 2 52 is meshed on the right side of the gear 1 51, and the gear 1 51 is driven to rotate by the output shaft of the driving motor 4, and then the rotating rod 53 is driven to rotate by the meshing of the gear 1 51 and the gear 2 52. The inner wall of the gear 2 52 is fixedly connected to the rotating rod 53, and the rotating rod 53 is hollow.

[0033] Reference Figure 2 and Figure 3 The outer wall of the rotating rod 53 is provided with a bearing at the connection between the outer wall of the rotating rod 53 and the movable plate 2. There are two groups of bearings, which are respectively arranged at the top and bottom ends of the movable plate 2 near the rotating rod 53, which can reduce the friction when the rotating rod 53 rotates, thereby reducing the wear of the rotating rod 53. The outer wall of the rotating rod 53 is provided with a slide groove 54, and the slide groove 54 is provided with three groups to ensure that the ball can slide along a specific path, so that the protective shell 55 slides on the outer wall of the rotating rod 53. The sliding assembly of the rotating rod 53 near the outer wall of the bottom end of the movable plate 2 is provided with a protective shell 55. The protective shell 55 can protect the through hole 58 opened on the rotating rod 53 to prevent soil from entering therein. The inner wall of the top of the protective shell 55 is provided with a ball. When the protective shell 55 slides along the outer wall of the rotating rod 53, the ball will slide in the slide groove 54, which helps to reduce friction and make the sliding smoother. The outer wall of the bottom end of the rotating rod 53 is provided with a threaded groove, through which the rotating rod 53 can be drilled into the ground to perform repair operations.

[0034] Reference Figure 3 and Figure 4The ball slides on the inner wall of the slide groove 54, and a through hole 2 58 is provided at the front end of the rotating rod 53 for spraying the repair liquid into the soil to be repaired. A guide groove 59 is provided at the rear side of the rotating rod 53, and the inner wall of the protective shell 55 slides on the inner wall of the guide groove 59 to drive the protective shell 55 and the rotating rod 53 to rotate synchronously. A through hole 1 57 is provided on the left side of the protective shell 55, and the number of through holes 2 58 and through holes 1 57 is the same. When the protective shell 55 moves along the slide groove 54, the through hole 1 57 is connected with the through hole 2 58, so that the repair liquid can be sprayed To repair the soil, a washer 56 is rotatably connected to the bottom side of the top of the protective shell 55. When the protective shell 55 is close to the ground, the washer 56 can contact the ground, so that the protective shell 55 obtains an upward force and moves along the slide groove 54. An anti-skid pad is provided at the bottom end of the washer 56. The anti-skid pad can increase the friction between the washer 56 and the ground, thereby reducing the synchronization rate between the washer 56 and the protective shell 55, and finally stops rotating under the downward pressure of the telescopic motor 3. At the same time, the protective shell 55 is moved along the slide groove 54 through the reverse force.

[0035] Reference Figure 1 and Figure 5 A liquid storage tank 8 is fixedly connected to the inner wall at the top of the frame 1 for storing repair liquid. A water pump 7 is fixedly connected to the top of the liquid storage tank 8. One end of a liquid injection pipe 6 is also fixedly connected to the top of the water pump 7. The other end of the liquid injection pipe 6 is arranged at the top of the rotating rod 53. The repair liquid inside the liquid storage tank 8 is injected into the rotating rod 53 through the liquid injection pipe 6 by the water pump 7 and sprayed through the through hole 2 58. A stabilizing component is arranged on the inner wall on the left side of the frame 1. The stabilizing component includes a fixed column 91. The outer wall of the bottom end of the fixed column 91 is slidably connected to the inner wall of the frame 1. The bottom end of the fixed column 91 is arranged in a pointed cone shape, which can be more conveniently inserted into the ground. A pedal 92 is fixedly connected to the left side of the fixed column 91. The right side of the pedal 92 slides on the inner wall of the frame 1. The arrangement of the pedal 92 can facilitate the operator to insert the fixed column 91 into the ground. A positioning groove 93 is provided on the rear side of the fixed column 91. Two groups of positioning grooves 93 are provided to limit the fixed column 91 in different states.

[0036] Reference Figure 5 The inner wall of the frame 1 is slidably connected with a slide bar 94 near the rear side of the positioning groove 93. The slide bar 94 is set in an L shape and can slide into the positioning groove 93 to limit the fixing column 91. The slide bar 94 is elastically connected to the frame 1 through a compression spring 95. The elastic force of the compression spring 95 can make the slide bar 94 stably inserted into the positioning groove 93. There are two groups of stabilizing components. The two groups of stabilizing components are symmetrically arranged with the center point of the frame 1 as the symmetry axis, which can improve the stability of the frame 1 and effectively stably control the torsion generated by the rotating rod 53 during the land hole rotation process, thereby ensuring the stability of the rotating rod 53 during operation and improving its work efficiency and accuracy.

[0037] Working principle: When in use, first start the two sets of telescopic motors 3 to drive the movable plate 2 to move downward, then start the driving motor 4, and drive the gear 1 51 to rotate through the output shaft of the driving motor 4, the gear 1 51 drives the gear 2 52 to rotate through meshing, the gear 2 52 drives the rotating rod 53 to rotate, and the friction force of the rotating rod 53 during rotation is reduced by the bearing, the rotating rod 53 drives the protective shell 55 to rotate synchronously through the guide groove 59, when the rotating rod 53 is rotated into the ground through the threaded groove, the protective shell 55 can block the through hole 2 58, effectively preventing soil from entering the through hole 2 58, significantly reducing the efficiency reduction problem caused by the blockage of the through hole, thereby improving the overall work progress and effect.

[0038] When the washer 56 contacts the ground, the friction with the ground is increased by the anti-skid pad, so that the synchronization rate of the washer 56 and the protective shell 55 is reduced, and finally stops rotating under the downward pressure of the telescopic motor 3. At the same time, since the telescopic motor 3 drives the rotating rod 53 to move downward, the multiple groups of balls on the protective shell 55 slide on the inner walls of the multiple groups of slide grooves 54, and slide on the inner walls of the guide grooves 59, so that the through hole 1 57 on the protective shell 55 is connected with the through hole 2 58, and the soil can be sprayed with repair liquid at this time.

[0039] Before the device is working, the frame 1 needs to be stabilized. First, the sliding rod 94 is pulled backward to squeeze the compression spring 95, so that the sliding rod 94 slides out of the positioning groove 93 on the lower side of the fixing column 91, and the restriction on the fixing column 91 is released. At this time, the operator can drive the fixing column 91 to be inserted into the ground by stepping on the pedal 92, and the sliding rod 94 slides into the inner wall of the positioning groove 93 on the upper side of the fixing column 91 under the reverse force of the compression spring 95, thereby restricting the fixing column 91, effectively stabilizing the torque generated by the rotating rod 53 during the soil hole rotation process, ensuring the stability of the rotating rod 53 during operation, and improving the working efficiency and accuracy of the device.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
