Description

Technical Field

[0001] This utility model relates to the field of continuous tube technology, specifically a continuous tube in-situ injection device. Background Technology

[0002] Soil remediation of contaminated sites can be categorized into ex-situ remediation and in-situ remediation, depending on the treatment location. In-situ remediation involves direct treatment on the contaminated site and, compared to ex-situ remediation, offers advantages such as simpler construction, lower cost, and less disturbance to the surrounding environment. Coiled tubing technology, originating in the oil drilling field, offers the core advantage of integrating drilling, chemical delivery, and dynamic monitoring through a single coiled tubing. In recent years, this technology has gradually expanded into the field of environmental remediation.

[0003] Traditional drill bits typically rotate downwards during drilling, which significantly increases drilling resistance, especially in complex geological conditions such as hard soil layers or highly viscous media, resulting in low drilling efficiency and high energy consumption. Therefore, a new technical solution is proposed to address this issue. Utility Model Content

[0004] The purpose of this invention is to provide a continuous tubular in-situ injection device, which solves the problem mentioned in the background art that traditional drill bits generally rotate downwards during drilling, and the drilling resistance increases significantly when encountering hard or viscous layers, resulting in low drilling efficiency and high energy consumption.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a continuous tube in-situ injection device, comprising a continuous tube body and a feed ring, wherein a drill bit is fixedly connected to the bottom of the continuous tube body, a bottom groove is formed on the inner side of the drill bit, a rotating rod is rotatably connected to the center of the bottom of the bottom groove, an impeller blade is fixedly connected in a circumferential array at the top of the side wall of the rotating rod, and an eccentric block is fixedly connected to the side wall of the rotating rod below the impeller blade.

[0006] In this technical solution, a bottom groove is set inside the drill bit. When the reagent enters, it impacts the impeller blades on the rotating rod, thereby driving the eccentric block to rotate and generating periodic vibration, which effectively reduces the resistance during drilling and improves drilling efficiency.

[0007] Preferably, the upper end of the side wall of the continuous tube body is provided with two limiting grooves, and the side wall of the continuous tube body between the two limiting grooves is provided with four side openings in a circumferential array.

[0008] Preferably, a limiting ring is fixedly connected to both the upper and lower openings of the inner sidewall of the feeding ring. The limiting ring is located inside the limiting groove. The continuous tube body is rotatably connected to the feeding ring. A feeding pipe is fixedly connected to the sidewall of the feeding ring and communicates with the feeding pipe.

[0009] Preferably, a feeding channel is provided on the inner side of the continuous tube body, the bottom end of the feeding channel is connected to a storage trough provided on the inner side of the feeding tube body, a sphere is provided on the inner side of the storage trough, and a plurality of spray nozzles are provided in a circumferential array on the inner sidewall of the storage trough.

[0010] Preferably, the inner sidewall of the bottom trough is provided with a plurality of discharge channels in a circular array, the discharge channels are connected to the spray nozzle, and the outer sidewall of the continuous pipe body corresponding to the horizontal height of the storage trough is fixedly connected with a ring-shaped protective net.

[0011] Preferably, the top end of the continuous tube body is rotatably connected to the bottom of the assembly base, a motor is fixedly connected to the inner side of the assembly base, the tail end of the motor's drive shaft is connected to the continuous tube body, and the assembly base and the feed ring are fixedly connected by a fixing block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model has a bottom groove inside the drill bit. When the reagent enters, it impacts the impeller on the rotating rod, thereby driving the eccentric block to rotate and generating periodic vibration. This effectively reduces drilling resistance, energy consumption, and the risk of stuck drill bit, and improves drilling efficiency.

[0014] 2. This utility model sets up a storage tank above the bottom tank. When the agent enters, it impacts the sphere inside the storage tank, causing the sphere to roll and rotate irregularly, generating a certain vibration that can be used to drill with the drill bit. At the same time, it can break the laminar flow state of the agent, making the agent more dispersed, promoting the mixing of the agent, and helping to improve the uniformity and stability of the agent.

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description will further elaborate on them in conjunction with specific embodiments.

[0023] A continuous tubular in-situ injection device, see Figures 1 to 5 The system includes a continuous tube body 1 and a feed ring 3. A drill bit 103 is fixedly connected to the bottom of the continuous tube body 1. A bottom groove 9 is opened on the inner side of the drill bit 103. A rotating rod 11 is rotatably connected to the center of the bottom of the bottom of the bottom groove 9. Impeller blades 111 are fixedly connected in a circular array at the top of the side wall of the rotating rod 11. An eccentric block 112 is fixedly connected to the side wall of the rotating rod 11 below the impeller blades 111. When the reagent enters, it impacts the impeller blades 111 on the rotating rod 11, thereby driving the eccentric block 112 to rotate and generate periodic vibration, which effectively reduces the resistance during drilling and improves drilling efficiency. Several discharge channels 10 are opened in a circular array on the inner side wall of the bottom groove 9. The discharge channels 10 are connected to the spray nozzle 701. The reagent entering the bottom groove 9 will flow along the discharge channels 10 to the spray nozzle 701 and be sprayed out together with the reagent in the storage tank 7 above. This can prevent the discharge channels 10 from being directly connected to the outside and prevent external sand and soil from entering.

[0024] Specifically, such as Figure 2 and Figure 3 As shown, two limiting grooves 102 are provided on the upper end of the side wall of the continuous tube body 1. Four side openings 101 are arranged in a circumferential array on the side wall of the continuous tube body 1 between the two limiting grooves 102. Limiting rings 301 are fixedly connected to the upper and lower openings of the inner side wall of the feed ring 3. The limiting rings 301 are located inside the limiting grooves 102. The continuous tube body 1 is rotatably connected to the feed ring 3. The side wall of the feed ring 3 is fixedly connected to the feed pipe 4 and communicates with the feed pipe 4. The medicine enters the feed ring 3 along the feed pipe 4 and then enters the interior of the continuous tube body 1 through the side openings 101 on the side wall of the continuous tube. The limiting rings 301 and the continuous tube body 1 rotate relative to each other. Therefore, it can be ensured that the feed ring 3 can maintain different states during the feeding process, while the continuous tube rotates normally. In order to maintain the seal, a sealing strip can be set at the part where the limiting ring 301 contacts the limiting groove 102 to prevent the medicine from leaking out.

[0025] Furthermore, such as Figure 4As shown, a feeding channel 6 is provided on the inner side of the continuous tube body 1. The bottom end of the feeding channel 6 is connected to a storage trough 7 provided on the inner side of the feed tube body 4. A sphere 8 is provided on the inner side of the storage trough 7. Several nozzles 701 are arranged in a circumferential array on the inner wall of the storage trough 7. The sphere 8 rotates under the impact of high-speed fluid, and the resulting vibration can vibrate together with the eccentric block 112 below, thereby facilitating the drilling of the drill bit 103. At the same time, its dynamic motion can break the laminar flow state of the agent, making the agent more dispersed. This dynamic The dispersion effect helps the agent to be sprayed more evenly through the spray holes on the outer wall of the cylinder, improving the coverage and uniformity of the spray. At the same time, the rotation of the sphere 8 can promote the mixing of the agent, which helps to improve the uniformity and stability of the agent. A ring-shaped protective net 12 is fixedly connected to the outer wall of the continuous pipe body 1 at the horizontal height of the storage tank 7. The protective net 12 is made of metal material, such as stainless steel. Its main purpose is to block larger rock and soil pieces and prevent them from entering the storage tank 7 through the spray nozzle 701.

[0026] It is worth noting that, such as Figure 4 As shown, the top end of the continuous tube body 1 is rotatably connected to the bottom of the mounting base 2. The inner side of the mounting base 2 is fixedly connected to the motor 5. The tail end of the drive shaft of the motor 5 is connected to the continuous tube body 1. After the motor 5 is started, it will drive the continuous tube body 1 and the drill bit 103 below to rotate, thereby realizing the drilling of the soil. In order to facilitate the connection, a coupling is set between the drive shaft of the motor 5 and the rotating shaft at the center of the top end of the continuous tube body 1. The mounting base 2 and the feed ring 3 are fixedly connected by the fixing block 201. The mounting base 2 remains fixed, so the feed ring 3 fixedly connected to it can also remain different, which facilitates feeding and avoids the feed tube 4 from getting tangled.

[0027] It should be noted that in order to allow the continuous tube body 1 to descend normally, a lifting device can be installed at the top of the mounting base 2, such as a hydraulic cylinder or an electric lifting rod. These are all relatively mature existing technologies and equipment, so their specific principles and internal structures will not be described in detail.

[0028] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.

[0029] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
