Description

Technical Field

[0001] This utility model relates to the field of pre-buried pipe extraction technology, specifically to a soil pre-buried pipe extractor. Background Technology

[0002] In farmland soil environmental monitoring, pre-buried measuring tubes (made of PVC or UPVC) are used as sensor carriers, permanently buried in the soil. These tubes, along with sensors, are used to monitor parameters such as soil temperature, humidity, and conductivity. After monitoring is complete, the pre-buried tubes need to be removed from the soil. However, due to the long burial time, the tubes tend to adhere to the soil, leading to the following technical problems during removal:

[0003] (1) The traditional mechanical gripping device is used to apply local stress to the wall of the pre-buried pipe and then remove the pipe body upward. During the removal process, the pipe body is prone to deformation and cracking. Not only is the removal process more laborious, but it is also easy to disturb and damage the surrounding soil, which can reduce the soil porosity by more than 30% and affect the reusability of subsequent monitoring points.

[0004] (2) Secondly, when using existing mechanical gripping devices to extract pre-buried pipes, most of them require electric drive. If the power supply around the pre-buried pipe location is difficult, the use of mechanical gripping devices is limited. Utility Model Content

[0005] The purpose of this invention is to provide a soil pre-buried pipe extractor to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a soil pre-buried pipe extractor, comprising a bottom positioning component and a driving component, wherein a middle connecting component and a top fixing component are detachably and fixedly assembled on the top of the bottom positioning component, and an elastic body is fixedly assembled between the bottom positioning component, the middle connecting component and the top fixing component.

[0007] Preferably, the bottom positioning component includes a bottom fixing plate, a positioning block is fixedly connected to the bottom of the bottom fixing plate, and a first fixing screw sleeve is fixedly connected to the top center of the bottom fixing plate.

[0008] Preferably, the central connector includes a central fixing plate, a first fixing screw is fixedly connected to the bottom of the central fixing plate, a second fixing sleeve is fixedly connected to the top of the central fixing plate, and a first driving groove is evenly formed on the side wall of the second fixing sleeve.

[0009] Preferably, the top fixing member includes a top fixing plate, a second fixing screw is fixedly connected to the bottom of the top fixing plate, a fixing block is fixedly connected to the top of the top fixing plate, a slot is provided on the side wall of the fixing block, a force-bearing block is fixedly connected to the top of the fixing block, and a second driving groove is uniformly provided on the side wall of the force-bearing block.

[0010] Preferably, a reinforcing block is fixedly connected between the side wall of the fixing block and the top fixing plate.

[0011] Preferably, the driving component includes a first driving body and a second driving body. The top of the first driving body is fixedly connected to a third fixing screw, the bottom of the second driving body is provided with a screw fixing groove, and the top of the second driving body is fixedly connected to a handle rod that is symmetrically distributed.

[0012] Preferably, the bottom of the first driving body is fixedly connected to a driving block that is evenly distributed around the circumference, and the middle part of the first driving body is integrally formed with a snap-fit ​​part.

[0013] Preferably, the outer side walls of the first and second driving bodies are fitted with anti-slip sleeves.

[0014] Compared with the prior art, the beneficial effects of this utility model are: a soil pre-buried pipe extractor, firstly, the utility model adopts a mechanical structure for operation, which simplifies the design of the mechanical mechanism. During use, it does not require power supply like traditional mechanical gripping devices. The utility model has a wider range of applications and higher applicability.

[0015] Meanwhile, this utility model adopts a segmented structural design. During the extraction of the pre-buried pipe, the elastic body can be compressed and fixed inside the pre-buried pipe through the cooperation of the middle connector and the top fixing part. Through the uniformly distributed expansion deformation of the elastic body, the elastic body can be tightly attached to the inner wall of the pre-buried pipe. The uniformly distributed contact pressure can avoid local stress concentration on the inner wall of the pre-buried pipe. During the upward extraction of the pre-buried pipe, the local stress deformation of the pre-buried pipe can be avoided to a large extent, which can improve the integrity of the pre-buried pipe during the extraction process. At the same time, since the pre-buried pipe can maintain a relatively stable shape during the extraction process, the interface between the pipe and the soil can be kept relatively stable, and the change rate of soil porosity can be controlled within 5%, reducing damage to the surrounding soil.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please see Figures 1 to 8 This utility model provides a technical solution: such as Figure 1 and Figure 2As shown, a soil pre-buried pipe extractor includes a bottom positioning component 1, a middle connecting component 2, a top fixing component 3, and a driving component 4. The bottom positioning component 1, middle connecting component 2, top fixing component 3, and driving component 4 are all cast from stainless steel. The bottom positioning component 1, middle connecting component 2, and top fixing component 3 are detachably and fixedly connected. Elastic bodies 5, made of rubber, are evenly assembled between the bottom positioning component 1, middle connecting component 2, and top fixing component 3. During use, the bottom positioning component 1... The middle connector 2 and the top fixing part 3 are sequentially assembled into the pre-embedded pipe. The fixing between the bottom positioning part 1, the middle connector 2 and the top fixing part 3 is driven by the driving part 4. After the bottom positioning part 1, the middle connector 2 and the top fixing part 3 are fixed, the elastic body 5 can be squeezed, causing the elastic body 5 to deform. After the elastic body 5 expands, the friction between it and the inner wall of the pre-embedded pipe can be greatly increased, exceeding the resistance of the soil to the pre-embedded pipe. Then, the driving part 4 is used to drag the whole structure upward, which makes it easy to remove the pre-embedded pipe from the soil.

[0027] like Figure 3 As shown, the bottom positioning component 1 includes a bottom fixing plate 11, a positioning block 12 integrally formed at the bottom center of the bottom of the bottom fixing plate 11, and a first fixing sleeve 13 integrally formed at the top of the bottom fixing plate 11. The elastic body 5 is sleeved on the outer wall of the first fixing sleeve 13. When the elastic body 5 is not squeezed by the structure above, its height position is higher than the first fixing sleeve 13. When the middle connecting component 2 and the top fixing component 3 are assembled and fixed in sequence by the driving component 4, the elastic body 5 can be compressed to deform and expand, thereby increasing the friction between it and the inner wall of the pre-embedded pipe.

[0028] like Figure 4 As shown, the middle connector 2 includes a middle fixing plate 21. The bottom of the middle fixing plate 21 is integrally formed with a first fixing screw 22, which is used to connect and fix with the first fixing sleeve 13. The top center of the middle fixing plate 21 is integrally formed with a second fixing sleeve 23. The side wall of the second fixing sleeve 23 is evenly provided with a first driving groove 24, which is used to connect with the driving component 4. The driving component 4 can drive the middle connector 2 to rotate inside the pre-embedded pipe. The middle connector 2 adopts a segmented design, and the number of segments assembled and fixed is selected according to the length of the pre-embedded pipe.

[0029] like Figure 5As shown, the top fixing member 3 includes a top fixing plate 31. A second fixing screw 32 is integrally formed at the bottom of the top fixing plate 31. The second fixing screw 32 is used to connect and fix with the second fixing sleeve 23. A fixing block 33 is integrally formed at the top center of the top fixing plate 31. A slot 34 is provided on the side wall of the fixing block 33. The slot 34 is used for the horizontal insertion of the driving member 4. The driving member 4 can drive the top fixing member 3 and the structure fixedly connected below it to be lifted upward, thereby removing the pre-buried pipe from the soil. A force-bearing block 35 is integrally formed on the top of the fixing block 33. A second driving groove 36 is evenly formed on the side wall of the force-bearing block 35. The second driving groove 36 is used to connect with the driving member 4. The driving member 4 can drive the top fixing member 3 to rotate, so that the top fixing member 3 is fixedly connected with the middle connecting member 2.

[0030] like Figure 5 As shown, a reinforcing block 37 is welded and fixed between the rear side wall of the fixing block 33 and the top fixing plate 31. By setting the reinforcing block 37, the overall stability of the fixing block 33 can be increased, so that when the driving component 4 is used to lift the overall structure and the pre-buried pipe from the soil upward, the fixing block 33 will deform.

[0031] like Figure 6 As shown, the driving component 4 includes a first driving body 41 and a second driving body 42. The top of the first driving body 41 is integrally formed with a third fixing screw 43. The bottom of the second driving body 42 is provided with a screw fixing groove 44 for screwing in the third fixing screw 43. The first driving body 41 and the second driving body 42 are detachably and fixedly connected to each other through the third fixing screw 43 and the screw fixing groove 44. The operation is simple and convenient. The first driving body 41 and the second driving body 42 can be disassembled and installed according to different usage conditions. The length of the first driving body 41 and the second driving body 42 after being connected and fixed is adapted to the length of the pre-embedded pipe to be extracted. The driving component 4 is selected according to the length of the pre-embedded pipe to be extracted. The top of the second driving body 42 is fixedly connected with a handle 45 that is symmetrically distributed on the axis. The handle 45 facilitates the rotation of the entire driving component 4.

[0032] The bottom of the first driving body 41 is integrally formed with driving blocks 411 evenly distributed in a circle. The number of driving blocks 411 matches the number of the first driving slot 24 and the second driving slot 36. After the driving blocks 411 are inserted into the first driving slot 24 or the second driving slot 36, the driving member 4 can drive the middle connecting member 2 and the top fixing member 3 to rotate. The middle part of the first driving body 41 is integrally formed with a snap-fit ​​part 412, which is used to connect with the slot 34. The outer side walls of the first driving body 41 and the second driving body 42 are respectively fixedly connected with anti-slip sleeves 46. The anti-slip sleeves 46 on the side wall of the first driving body 41 are symmetrically distributed up and down with the snap-fit ​​part 412 as the center. When the first driving body 41 is horizontally set, the anti-slip sleeves 46 on the side wall of the first driving body 41 facilitate the upward lifting of the overall structure. The anti-slip sleeves 46 on the side wall of the second driving body 42 facilitate the assembly and disassembly of the first driving body 41 and the second driving body 42.

[0033] Working principle: such as Figure 1 , Figure 7 and Figure 8 As shown, when using this invention to extract a pre-buried pipe located in the soil, firstly, an elastic body 5 is fitted onto the top of the bottom positioning member 1. Then, the bottom positioning member 1 is inserted into the pre-buried pipe with the positioning block 12 pointing downwards. The positioning block 12 is inserted into the soil at the bottom of the pre-buried pipe. Then, the elastic body 5 and the middle connecting member 2 are assembled in sequence. After a middle connecting member 2 with an elastic body 5 is inserted into the pre-buried pipe, the driving member 4 is used to connect the middle connecting member 2 inserted into the pre-buried pipe with the bottom positioning member 1, so that the driving member 4 at the top of the driving member 4... Block 411 is inserted into the first drive groove 24 at the top of the middle connector 2. The middle connector 2 is pressed down by the handle 45. Then, the rotation of the middle connector 2 can connect and fix the first fixing screw 22 at the bottom to the first fixing sleeve 13. The downward pressure of the middle connector 2 can squeeze the elastic body 5 on the outer wall of the bottom positioning part 1. After the elastic body 5 expands, it fits tightly against the inner wall of the pre-embedded pipe, increasing the friction between the elastic body 5 and the inner wall of the pre-embedded pipe. This can also connect and fix the bottom positioning part 1 and the middle connector 2 after connection.

[0034] Then, according to the length of the pre-buried pipe, the middle connector 2 is assembled in sections. Each middle connector 2 is connected and fixed to the previous middle connector 2 through the driving component 4. Finally, the top fixing component 3 is fixed to the top of the uppermost middle connector 2. Due to the segmented arrangement, each middle connector 2 will squeeze the elastic body 5 below it, causing it to deform. The expanded elastic body 5 can fit against the inner wall of the pre-buried pipe. After the top fixing component 3 is fixed, the driving component 4 is disassembled, so that the first driving body 41 and the second driving body 42 of the driving component 4 are separated. Then, the snap-fit ​​part 412 of the first driving body 41 is inserted into the slot 34 on the side wall of the fixing block 33. The pre-buried pipe can be taken out of the soil by lifting it upwards with both hands. By lifting the pre-buried pipe with this utility model, the integrity of the pipe body can be ensured after the pre-buried pipe is taken out, and the impact on the change rate of the porosity of the surrounding soil can be reduced.
