Description

Technical Field

[0001] This invention relates to the field of underground pipeline protection technology, and in particular to an underground pipeline protection device. Background Technology

[0002] Underground high-voltage lines play a vital role in urban power transmission. Damage to them will directly affect the city's power supply and residents' normal lives. Therefore, protective measures are necessary for underground high-voltage pipelines.

[0003] The authorized announcement number "CN108532636B" discloses an underground pipeline protection device and its construction method, which describes the technical problem of "using the first rib and the second rib to divide the space between the base and the top cover into four parts: the first channel, the second channel, the third channel and the fourth channel, and installing the pipeline in the first channel, the second channel and the third channel for protection. When the top cover is under pressure, the force will be transmitted and dispersed through the arch structure, so that the top cover and the base can withstand greater force".

[0004] In the process of implementing this patent, the applicant discovered the following technical problems:

[0005] Because the protective device described in this patent has a rear-fastening top cover, gaps will appear around the top cover after installation. During rainy weather, rainwater will flow into the device through these gaps and accumulate. Prolonged accumulation and soaking will corrode or otherwise damage the outer sheath of the pipeline. At the same time, since the top cover and bottom support are fixed, the pressure dispersion effect is low when under pressure, which will reduce the protection effect on the internal pipeline. Therefore, it is necessary to propose an underground pipeline protection device to provide a new technical solution to solve the technical problems mentioned in the above patent. Summary of the Invention

[0006] Based on this, an underground pipeline protection device is provided to solve the following technical problems mentioned in the background art: Because the protection device set in this patent has a top cover that is installed by snapping it on later, gaps will be generated around the top cover after installation. During rainy weather, rainwater will flow into the device through the gaps and accumulate. Long-term accumulation and soaking will cause corrosion or other damage to the outer sheath of the pipeline. At the same time, since the top cover and the bottom support are fixed, the pressure dispersion effect is low when under pressure, which will reduce the protection effect on the internal pipeline.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0035] As in the background art, due to the protective device set in this patent, since the top cover is installed by snapping it on, gaps will be generated around the top cover after installation. In rainy weather, rainwater will flow into the device through the gaps and accumulate. Long-term accumulation and soaking will cause corrosion or other damage to the outer sheath of the pipeline. At the same time, since the top cover and the bottom support are fixed, the pressure dispersion effect is low when under pressure, which will reduce the protection effect on the internal pipeline.

[0036] To address this technical problem, the present invention provides an underground pipeline protection device. By incorporating drainage into the protection device, rainwater can be prevented from accumulating and damaging the pipeline during rainy weather. Furthermore, by inverting the pipeline, the bottom of the pipeline can be prevented from contacting the bottom of the device, thereby further enhancing the protection effect on the pipeline.

[0049] The protective drainage composite component 2 also includes a first hollow plate 12, a dual-head motor 13, and threaded rods 14. The bottom of the capping box 4 is fixedly connected to the first hollow plate 12, and the first hollow plate 12 is located between two first fixed plates 7 and above the first fixed column 8.

[0050] The protective drainage composite component 2 also includes a first rotating seat 15, a second rotating seat 16, and a first linkage rod 17. The first rotating seat 15 is fitted with both ends of the inner side of the first hollow plate 12 with a clearance fit. The first rotating seat 15 is threadedly connected to the threaded rod 14. The two ends of the two first arc-shaped plates 9 that are far apart from each other are fixedly connected to the second rotating seat 16. The first linkage rod 17 is provided between the second rotating seat 16 and the first rotating seat 15. The top and bottom of the first linkage rod 17 are rotatably connected to the first rotating seat 15 and the second rotating seat 16, respectively.

[0051] The protective drainage composite component 2 also includes a guide box 18, a support plate 19, and a second arc plate 20. The guide box 18 is fixedly connected to the center of the bottom of the inner side of the protective box 1. Both ends of the top of the guide box 18 are inclined. There is a gap between the two ends of the guide box 18 and the side walls of the two ends of the protective box 1. Multiple drainage holes are opened at the bottom of both ends of the protective box 1. The two ends of the top of the guide box 18 are fixedly connected to the support plate 19. The top of the two support plates 19 is fixedly connected to the second arc plate 20. The top of both ends of the second arc plate 20 is provided with a reserved groove, and the reserved groove is clearance-fitted with the second rotating seat 16.

[0052] The protective drainage composite component 2 also includes a single-head motor 21, a first gear 22, a second gear 23, and a second fixed post 24. The single-head motor 21 is fixedly connected to the top of one end of the inner side of the guide box 18. The first gear 22 is fixedly connected to the output end of the bottom of the single-head motor 21. The second gear 23 is rotatably connected to the top of the other end of the inner side of the guide box 18. The second gear 23 and the first gear 22 are meshed. The bottom of both the first gear 22 and the second gear 23 are fixedly connected to the second fixed post 24, and the second fixed post 24 is located away from the center of the first gear 22 and the second gear 23.

[0053] The protective drainage composite component 2 also includes a first movable plate 25, a cleaning rod 26, a second fixed plate 27, a third fixed column 28, and a second linkage rod 29. The first movable plate 25 is provided at both ends of the inner side of the guide box 18. Multiple cleaning rods 26 are fixedly connected to the first movable plate 25 at positions away from the center of the guide box 18. The number and position of the cleaning rods 26 correspond to the drainage holes, and each cleaning rod 26 penetrates the side walls at both ends of the guide box 18 and is clearance-fitted to the inner side of the drainage holes. A second fixed plate 27 is fixedly connected to the middle of the end of the first movable plate 25 away from the cleaning rods 26. A third fixed column 28 is fixedly connected to the bottom of the second fixed plate 27. A second linkage rod 29 is provided between the third fixed column 28 and the second fixed column 24, and the two ends of the second linkage rod 29 are rotatably connected to the second fixed column 24 and the third fixed column 28, respectively.

[0054] Specifically: When pipeline protection is required, by turning on the dual-head motor 13, the threaded rod 14 can be driven to rotate inside the first hollow plate 12. Through the threaded connection between the threaded rod 14 and the first rotating seat 15, the first rotating seat 15 can be driven to move laterally inside the first hollow plate 12.

[0055] When the two first rotating seats 15 move toward one end closer to each other, they can drive the top of the first linkage rod 17 to move toward one end closer to each other. At the same time, through the squeezing effect of the first arc plate 9 on the first linkage rod 17, the first linkage rod 17 can be tilted, thereby causing the first linkage rod 17 to drive the bottom second rotating seat 16 to move toward one end further away from each other. This can drive the first arc plate 9, which is fixedly connected to the second rotating seat 16, to move synchronously. At the same time, through the rotational connection effect between the first arc plate 9 and the first fixed column 8, the two first arc plates 9 can be opened, and then the pipeline can be placed between the two first arc plates 9.

[0056] By setting the extrusion plate 11 and the first spring 10, the clamping effect on various pipes of different thicknesses can be improved, thereby expanding the applicability of the protection device. At the same time, by setting the elasticity of the first spring 10, the extrusion plate 11 can be used to extrude the extrusion effect on the outside of the pipe, thereby improving the stability of the pipe clamping.

[0057] After clamping the pipeline, by driving the handle 6, the capping box 4 can be placed on top of the protective box 1, so that the pipeline clamped at the bottom of the capping box 4 can be placed inside the protective box 1, and the bottom two ends of the capping box 4 can be inserted into the top of the protective box 1, so that the pipeline can be fixed inside the protective box 1.

[0058] At the same time, the two first arc-shaped plates 9 that are fastened together will be placed on the inner side of the top of the second arc-shaped plate 20. The setting of the second arc-shaped plate 20 can further stabilize the clamping of the pipe by the two first arc-shaped plates 9.

[0059] In rainy weather or when water enters the inside of the protective box 1, the guide box 18 is inclined at both ends, which can guide the water to the drain holes at both ends of the protective box 1 and make the water flow into the gap between the two ends of the guide box 18 and the side walls at both ends of the protective box 1, and guide the water out of the outside of the protective box 1 through the drain holes at both ends of the protective box 1.

[0060] At the same time, by turning on the single-head motor 21, the first gear 22 can be driven to rotate inside the guide box 18, thereby driving the second gear 23 meshing with the first gear 22 to rotate synchronously, thereby driving the second fixed column 24 at the bottom of the first gear 22 and the second gear 23 to move away from the center position.

[0061] By positioning the second fixed column 24 away from the center, the second fixed column 24 can move around the first gear 22 and the second gear 23, while simultaneously driving the second linkage rod 29 to move synchronously. Through the connection of the second linkage rod 29, the first movable plate 25 can be driven to move laterally back and forth inside the guide box 18.

[0062] When the first movable plate 25 moves toward the end closer to the drain hole, it can drive multiple cleaning rods 26 to be inserted into the inside of the drain hole simultaneously. Through the gap fit between the cleaning rods 26 and the drain hole, the inside of the drain hole can be unblocked, thereby improving the drainage effect inside the protective box 1.

[0063] Example 3:

[0064] This embodiment 3 further discloses the specific structure of the buffer component 3 based on the above embodiments. By cooperating with the structure in the above embodiments, the buffer component 3 can buffer and disperse the pressure when the top of the device is under pressure, thereby improving the protection effect on the pipeline.

[0065] The underground pipeline protection device provided in Embodiment 1 and Embodiment 2 is further optimized, specifically, as follows: Figures 8-9As shown, the buffer assembly 3 includes a second hollow plate 30, a support plate 31, a second movable plate 32, a first fixing rod 33, and a second spring 34. The two ends of the inner side of the top box 4 are fixedly connected to the second hollow plate 30. The top of the top box 4 is provided with a support plate 31. The two ends of the bottom of the support plate 31 are fixedly connected to the second movable plate 32. The second movable plate 32 is clearance-fitted with the inner side of the second hollow plate 30. The two sides of the inner side of the second hollow plate 30 are fixedly connected to the first fixing rod 33. The first fixing rod 33 is slidably connected to the bottom of the second movable plate 32. The second spring 34 is provided on the outer side of the second movable plate 32. The second spring 34 is located at the bottom of the second movable plate 32, and the top and bottom of the second spring 34 are fixedly connected to the bottom of the second movable plate 32 and the inner side of the second hollow plate 30, respectively.

[0066] The buffer assembly 3 also includes a movable block 35, a second fixed rod 36, a third movable plate 37, a third rotating seat 38, and a third linkage rod 39. The movable block 35 is fixedly connected to the center of the bottom of the support plate 31. The second fixed rods 36 are fixedly connected to both sides between the two second hollow plates 30. The two ends of the inner side of the top box 4 are fitted with the third movable plate 37 with clearance. The inner sides of both sides of the third movable plate 37 are fitted with the corresponding second fixed rods 36 with clearance. The two sides of the top of the third movable plate 37 are fixedly connected with the third rotating seat 38. The top of the third rotating seat 38 is rotatably connected with the third linkage rod 39. Rotation grooves are opened on both sides of both ends of the movable block 35. The positions of the rotation grooves correspond to the third rotating seat 38, and the top of the third linkage rod 39 is rotatably connected to the inner side of the rotation groove.

[0067] The buffer assembly 3 also includes a third spring 40 and a fourth spring 41. The outer sides of both ends of the second fixed rod 36 are provided with a third spring 40, and the third spring 40 is located between the third movable plate 37 and the second hollow plate 30. The two ends of the third spring 40 are fixedly connected to the third movable plate 37 and the second hollow plate 30 respectively. The fourth spring 41 is fixedly connected between the two third movable plates 37.

[0068] Specifically: When the top of the capping box 4 is pressed, the pressure will first press the support plate 31 downward. As the support plate 31 moves downward, it can drive the second movable plates 32 at both ends to move downward synchronously inside the second hollow plate 30. At this time, the bottom of the second movable plate 32 can squeeze the second spring 34. Through the elastic setting of the second spring 34, it can buffer the second movable plate 32 when it moves downward.

[0069] As the support plate 31 moves downward, it can drive the movable block 35 to move downward synchronously. At this time, the movable block 35 can drive the third linkage rod 39 to move downward synchronously. Since the bottom of the third linkage rod 39 and the third rotating seat 38 at the top of the third movable plate 37 are rotatably connected, when the movable block 35 moves downward, the third movable plate 37 can be pushed away from the movable block 35 by the connection of the third linkage rod 39.

[0070] When the third movable plate 37 moves away from the movable block 35, it can exert a squeezing effect on the third spring 40. At the same time, the elastic setting of the third spring 40 can buffer the movement of the third movable plate 37, thereby further buffering the downward pressure of the second movable plate 32.

[0071] When the two third movable plates 37 move to opposite ends, they can stretch the fourth spring 41. At the same time, the elastic setting of the fourth spring 41 can buffer the downward pressure of the second movable plate 32, thereby further improving the protection effect of the support plate 31 on the pipeline.

[0072] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
