Abstract
Description
Technical Field
[0001] This invention relates to the field of soil remediation technology, and in particular to a high-pressure rotary injection device for soil remediation. Background Technology
[0002] Soil pollution remediation is an important part of ecological and environmental protection. High-pressure injection of soil remediation solution into the contaminated soil, allowing the solution to fully contact and react with the contaminated soil, is one of the mainstream technical methods in the field of soil chemical remediation.
[0003] In actual soil remediation operations, the efficiency of the chemical injection device, the ease of adjusting the injection depth, and the sufficient contact between the remediation solution and the soil directly determine the soil remediation effect and the overall construction cost.
[0004] Currently, most existing soil remediation chemical injection devices adopt a direct injection structure, which has many technical drawbacks in practical applications: Firstly, the drill bit adopts a straight-in-soil-entry method, which results in high soil resistance. This not only requires more power, but also makes it prone to problems such as drill bit jamming and difficulty in entering the soil in areas with hard soil. Furthermore, the process of adjusting the injection depth is cumbersome. Secondly, the remediation solution is mostly injected in a one-way direct spray, which limits the diffusion range. The remediation solution can only be distributed in a small area at the injection point, resulting in a small contact area with the contaminated soil and insufficient integration. This leads to a significant reduction in the soil remediation effect. Some contaminated areas cannot be covered by the remediation solution and require repeated injections, which reduces the overall work efficiency.
[0005] In summary, a high-pressure rotary injection device for soil remediation is therefore needed. Summary of the Invention
[0006] The main objective of this invention is to provide a high-pressure rotary injection device for soil remediation, which can effectively solve the problems mentioned above.
[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A high-pressure rotary injection device for soil remediation, including a trolley, and further comprising: A storage tank, which is mounted on the upper part of the trolley via a first support rod, is used to store soil remediation solution; A fixing cylinder is provided at the lower part of the trolley 1 and is installed at the lower part of the trolley via a second support rod; The first electric telescopic cylinder is located on the upper middle side of the liquid storage tank. The output end of the first electric telescopic cylinder is provided with a transmission rod. The transmission rod passes through the liquid storage tank and extends into the interior of the fixed cylinder, and is provided with a telescopic cylinder. A guide assembly is disposed in the inner cavity of the fixed cylinder and connected to the telescopic cylinder, for spiral guiding the telescopic cylinder; A conveying assembly is disposed inside a fixed cylinder and connected to a liquid storage tank and a telescopic cylinder, respectively; The drill bit is located at the bottom of the telescopic cylinder.
[0008] Preferably, the liquid storage tank has a liquid inlet on the upper rear side.
[0009] Preferably, the conveying assembly includes: Two high-pressure water pumps are respectively installed on the front and rear sides of the lower part of the liquid storage tank, and each of the two high-pressure water pumps is equipped with a telescopic pipe at its output end; An infusion shell is disposed on the upper part of the outer surface of a telescopic cylinder, and an infusion chamber is provided in the upper part of the telescopic cylinder; An infusion tube is installed inside a telescopic cylinder and communicates with an infusion chamber. Four high-pressure nozzles are arranged in a ring on the lower part of the outer surface of the infusion tube. Four protective shells are arranged in a ring on the upper part of the outer surface of the drill bit and correspond to the four high-pressure nozzles. A swing mechanism, located at the bottom of the drill bit, is used to drive the four protective shells to swing open, so that the high-pressure nozzle can spray out the soil remediation fluid.
[0010] Preferably, the infusion shell is in communication with the infusion cavity.
[0011] Preferably, the guiding component includes: Two helical tracks are provided on the inner surface of the fixed cylinder and are symmetrical about each other in opposite directions. Two fixed rods are respectively set on the left and right sides of the outer surface of the telescopic cylinder, and each of the two fixed rods is provided with a sliding ball at the part that is far apart from each other; Both sliding balls move within two helical tracks to guide the telescopic cylinder in rotational motion.
[0012] Preferably, the swing mechanism includes: The second electric telescopic cylinder is located at the center of the bottom of the drill bit, and the output end of the second electric telescopic cylinder is provided with a conical block.

[0013] Preferably, all four push rods are Z-shaped, with their upper parts connected to the four protective shells respectively.
[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The high-pressure rotary injection device for injecting medicine in this invention achieves the screw-in insertion of the drill bit into the soil through a guide component and a first electric telescopic cylinder, reducing power consumption and effectively avoiding the problems of drill bit jamming and difficulty in soil insertion in hard soil areas; at the same time, relying on the telescopic adjustment of the electric telescopic cylinder and the linkage structure of the spiral guide, the injection depth can be adjusted conveniently and accurately, simplifying the operation process. A single person can complete the depth control operation, improving the adaptability and ease of operation of the device under different soil conditions.
[0015] 2. This invention achieves high-pressure rotary injection of the remediation fluid through a delivery component. Combined with a ring-shaped high-pressure nozzle design, this significantly increases the diffusion range of the remediation fluid in the soil, enhances the contact area between the fluid and contaminated soil, and ensures full fusion, fundamentally improving the soil remediation effect. It avoids situations where localized contaminated areas are not covered, reduces the need for repeated injections, and improves the overall efficiency of soil remediation operations. Simultaneously, the added rotating mechanism and protective shell structure effectively protect the high-pressure nozzles during drill bit entry and exit, preventing soil particles from clogging the nozzles, ensuring the continuity and stability of the solution delivery, reducing the device's failure rate, and lowering construction and maintenance costs.

[0018] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0019] In soil remediation operations, workers need to inject soil remediation solution into the soil to be remediated, so that the solution can fully contact the contaminated soil to achieve the remediation effect. However, traditional solution injection devices are mostly direct pressure injection, which not only makes it difficult to drill into the soil and adjust the injection depth, but also has the problems of small solution diffusion range and insufficient contact with the soil. At the same time, the nozzle is directly exposed and is easily blocked by the soil, affecting the delivery of solution. In addition, some devices are cumbersome to operate and require multiple people to cooperate, resulting in low work efficiency. Therefore, a high-pressure rotary injection device for soil remediation is needed.
[0020] Example 1, as Figure 1 , Figure 2 and Figure 3 As shown, a high-pressure rotary injection device for soil remediation includes a trolley 1, a storage tank 2 mounted on the upper part of the trolley 1 via a first support rod, an inlet on the upper rear side of the storage tank 2, a fixed cylinder 4 mounted on the lower part of the trolley 1 via a second support rod, a first electric telescopic cylinder 3 mounted on the upper middle side of the storage tank 2, a transmission rod at the output end of the first electric telescopic cylinder 3, the transmission rod extending through the storage tank 2 to the inside of the fixed cylinder 4 and connected to a telescopic cylinder 7, a drill bit 8 mounted on the lower part of the telescopic cylinder 7, a guide assembly 6 connected to the telescopic cylinder 7 in the inner cavity of the fixed cylinder 4, and a conveying assembly 5 connected to the storage tank 2 and the telescopic cylinder 7 respectively inside the fixed cylinder 4. Guide assembly 6 is installed in the inner cavity of the fixed cylinder 4 and connected to the telescopic cylinder 7, and is used to provide helical guidance for the telescopic cylinder 7; The conveying component 5 is installed inside the fixed cylinder 4. One end is connected to the storage tank 2 and the other end is connected to the telescopic cylinder 7. It is used to convey the remediation liquid in the storage tank 2 under high pressure and inject it into the soil by rotation. The two components work together to realize the core function of high-pressure rotary injection of the device.
[0021] During implementation, the staff first pushes the device to the area of soil to be repaired using a trolley 1, and adds sufficient soil remediation liquid into the storage tank 2 through the inlet. Then, the staff activates the first electric telescopic cylinder 3, which pushes the telescopic cylinder 7 and the drill bit 8 downward through the transmission rod. Under the action of the guide component 6, the telescopic cylinder 7 drives the drill bit 8 to rotate downward, so that the drill bit 8 spins into the soil. After the drill bit 8 and the telescopic cylinder 7 have moved down to the preset liquid injection depth, the staff activates the delivery component 5 to inject the soil remediation liquid in the storage tank 2 into the soil in a high-pressure rotating manner, completing the liquid injection operation for a single soil area.
[0022] In the above process, after the chemical solution is injected into the area, the staff first shuts off the conveying component 5, then starts the first electric telescopic cylinder 3 to retract its output end. The transmission rod drives the telescopic cylinder 7 and the drill bit 8 to move upward. With the cooperation of the guide component 6, they rotate upward to move the drill bit 8 out of the soil. Then the staff pushes the cart 1 to the next soil area to be remediated. Repeating the above operation will complete the soil remediation chemical solution injection operation for the entire area.
[0023] This embodiment is based on the first embodiment, and further explains the guide component 6 and the conveying component 5. In the second embodiment, the guide component 6 includes two spiral tracks 61 arranged symmetrically in opposite directions on the inner surface of the fixed cylinder 4. Fixed rods 62 are installed on both the left and right sides of the outer surface of the telescopic cylinder 7. Sliding balls 63 are installed at the ends of the two fixed rods 62 that are far apart from each other, and the two sliding balls 63 move within the inner cavity of the two spiral tracks 61.
[0024] In the above, the implementation process of the guide component 6 is as follows: the output end of the first electric telescopic cylinder 3 pushes the transmission rod to move down, and the transmission rod drives the telescopic cylinder 7 to slide down inside the fixed cylinder 4. At this time, the sliding balls 63 at the ends of the fixed rods 62 on both sides of the telescopic cylinder 7 will slide synchronously in the spiral track 61 on the inner wall of the fixed cylinder 4. Since the two spiral tracks 61 are designed in opposite directions and symmetrically, they can guide and limit the sliding of the sliding balls 63, so that the sliding balls 63 move along the trajectory of the spiral track 61, thereby driving the telescopic cylinder 7 to rotate while moving down. The telescopic cylinder 7 then drives the lower drill bit 8 to rotate, realizing the screw-in soil entry of the drill bit 8.
[0025] Furthermore, the delivery assembly 5 includes two high-pressure water pumps 51 respectively located on the front and rear sides of the lower part of the storage tank 2. The output ends of the two high-pressure water pumps 51 are equipped with telescopic pipes 52. A delivery shell 53 is installed on the upper part of the outer surface of the telescopic cylinder 7. A delivery chamber 54 communicating with the delivery shell 53 is opened on the upper part of the telescopic cylinder 7. A delivery pipe 55 communicating with the delivery chamber 54 is installed inside the telescopic cylinder 7. Four high-pressure nozzles 56 are arranged in a ring on the lower part of the outer surface of the delivery pipe 55. Four protective shells 57 corresponding to the high-pressure nozzles 56 are arranged in a ring on the upper part of the outer surface of the drill bit 8. A swing mechanism 58 for driving the protective shells 57 to swing open is also provided at the bottom of the drill bit 8.
[0026] In the above, the implementation process of the delivery component 5 is as follows: After the drill bit 8 is screwed into the soil to the preset depth, the staff first starts the opening mechanism 58, so that the four protective shells 57 are opened simultaneously, exposing the corresponding high-pressure nozzles 56. Then, the two high-pressure water pumps 51 are started to work. The high-pressure water pumps 51 draw soil remediation liquid from the storage tank 2 and deliver it to the delivery shell 53 through the telescopic pipe 52. The remediation liquid enters the delivery chamber 54 through the delivery shell 53, and then flows into the delivery pipe 55 from the delivery chamber 54. Finally, it is delivered to the four high-pressure nozzles 56. Under the pressure of the high-pressure water pumps 51, the remediation liquid is sprayed out from the high-pressure nozzles 56 at high pressure. Meanwhile, the telescopic cylinder 7 continues to rotate under the action of the guide component 6, which in turn drives the infusion pipe 55 and the high-pressure nozzle 56 to rotate, so that the remediation liquid is sprayed into the soil in a rotating manner, which greatly increases the diffusion range of the remediation liquid, allows the remediation liquid to fully contact the soil, and improves the soil remediation effect. The telescopic pipe 52 can extend and retract with the up and down movement of the telescopic cylinder 7 to ensure the continuity of the remediation liquid delivery and prevent the liquid from being interrupted due to the movement of the device.
[0027] Furthermore, the swing mechanism 58 includes a second electric telescopic cylinder 581 located at the center of the bottom of the drill bit 8. The output end of the second electric telescopic cylinder 581 is provided with a conical block 582. Four telescopic rods 584 are distributed in a ring on the lower part of the outer surface of the infusion tube 55. Each of the four telescopic rods 584 is provided with a Z-shaped push rod 583 at one end away from the axis of the infusion tube 55, and the upper part of the four push rods 583 is connected to four protective shells 57 respectively.
[0028] In the above, the implementation process of the swing mechanism 58 is as follows: When the protective shell 57 needs to be opened, the staff starts the second electric telescopic cylinder 581 to work. Its output end pushes the conical block 582 to move upward. The conical surface of the conical block 582 will squeeze the four telescopic rods 584, causing the four telescopic rods 584 to unfold to the outside away from the axis of the infusion tube 55. The telescopic rods 584 drive the bottom Z-shaped push rod 583 to move synchronously. The push rod 583 pulls the protective shell 57 connected to it to swing around the connection point, thereby exposing the high-pressure nozzle 56 for easy spraying of medicine. After the liquid medicine is injected, the staff controls the output end of the second electric telescopic cylinder 581 to retract, which drives the conical block 582 to move downward. The squeezing force of the conical block 582 on the telescopic rod 584 disappears, and the telescopic rod 584 returns to the axis of the infusion tube 55 under its own elasticity. The telescopic rod 584 drives the push rod 583 to move in the opposite direction. The push rod 583 pushes the protective shell 57 to screw back and reset, covering the high-pressure nozzle 56 again, thus protecting the high-pressure nozzle 56 and preventing soil particles from entering the nozzle and causing blockage when the drill bit 8 is screwed into or removed from the soil, ensuring the normal use of the high-pressure nozzle 56.
[0029] It should be noted that the specific installation methods, circuit connection methods, and control methods of the first electric telescopic cylinder 3, the second electric telescopic cylinder 581, and the high-pressure water pump 51 used in this invention are all conventional designs, and will not be described in detail in this invention.
