Description

DETAILED DESCRIPTION

[0021] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the present invention will be briefly introduced below in conjunction with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0022] Example:

[0023] like Figure 1-Figure 3 As shown, this embodiment provides a tunnel anti-crystallization pipeline device, which is arranged in the pavement main body 2 under the tunnel 1, including a central drainage pipe 3 opened in the middle of the pavement main body 2 and horizontal drainage pipes 4 arranged at both left and right ends of the pavement main body 2, and one end of the horizontal drainage pipe 4 is connected to the inside of the central drainage pipe 3. The central drainage pipe 3 discharges tunnel seepage and leakage, and then discharges it to the outside through the horizontal drainage pipe 4. The horizontal drainage pipe 4 is connected to the outer surface of a transmission sleeve 5, which is mainly used as a structural transmission. The transmission sleeve 5 is connected to the outer surface of an installation outer tube 6 to facilitate the installation of the transmission sleeve 5. The transmission sleeve 5 is rotatably connected to the installation outer tube 6, thereby ensuring the stable rotation of the transmission sleeve 5. The rotational connection mode of the transmission sleeve 5 relative to the installation outer tube 6 can be that the transmission sleeve 5 is directly rotatably connected to the installation outer tube 6, or that the transmission sleeve 5 is rotatably connected to other components and parts. The transmission sleeve 5 and the installation outer tube 6 are only in a rotational relationship, so that the transmission sleeve 5 is limited by the installation outer tube 6. The specific implementation method is not limited.

[0024] The outer tube 6 is provided with a bidirectional driving mechanism, which can rotate forward or reverse. The bidirectional driving mechanism can drive the transmission sleeve 5 to rotate forward or reverse inside the outer tube 6, and can be adjusted according to actual conditions. A magnetic attraction ring 7 is sleeved on the outer wall of the horizontal drain pipe 4, and the outer wall of the magnetic attraction ring 7 is threadedly connected to the inner wall of the transmission sleeve 5. When the transmission sleeve 5 rotates forward, the transmission sleeve 5 can drive the magnetic attraction ring 7 to move spirally in one direction, and when the transmission sleeve 5 is reversed, the transmission sleeve 5 can drive the magnetic attraction ring 7 to move spirally in the opposite direction. An annular crystal removal brush 8 is provided in the water pipe 4. The annular crystal removal brush 8 can remove crystals on the inner wall of the horizontal drainage pipe 4. The annular crystal removal brush 8 is tightly attached to the inner wall of the horizontal drainage pipe 4 and is magnetically connected to the magnetic adsorption ring 7. The stability of the annular crystal removal brush 8 is ensured by the magnetic connection, so that the annular crystal removal brush 8 can move with the magnetic adsorption ring 7, and then when the transmission sleeve 5 drives the magnetic adsorption ring 7 to move in a forward spiral or reverse spiral, the magnetic adsorption ring 7 can drive the annular crystal removal brush 8 to move in a forward spiral or reverse spiral, thereby effectively removing the crystals on the inner wall of the horizontal drainage pipe 4.

[0025] The present invention has a transmission sleeve 5 connected to the outer side of the horizontal drain pipe 4, and an installation outer tube 6 is connected to the outer side of the transmission sleeve 5, which is convenient for installing the transmission sleeve 5. The transmission sleeve 5 is rotatably connected to the installation outer tube 6, thereby ensuring the stable rotation of the transmission sleeve 5. A bidirectional driving mechanism is installed outside the installation outer tube 6. The bidirectional driving mechanism can rotate forward or reverse. The bidirectional driving mechanism can drive the transmission sleeve 5 to rotate forward or reverse inside the installation outer tube 6. A magnetic attraction ring 7 is sleeved on the outer wall of the horizontal drain pipe 4. The outer wall of the magnetic attraction ring 7 is threadedly connected to the inner wall of the transmission sleeve 5. When the transmission sleeve 5 rotates forward, the transmission sleeve 5 can drive the magnetic attraction ring 7 to move spirally in one direction, and when the transmission sleeve 5 reverses The transmission sleeve 5 can drive the magnetic adsorption ring 7 to move in the opposite direction in a spiral manner; an annular crystal removal brush 8 is provided in the horizontal drain pipe 4, and the annular crystal removal brush 8 can remove the crystals on the inner wall of the horizontal drain pipe 4. The annular crystal removal brush 8 is tightly attached to the inner wall of the horizontal drain pipe 4 and is magnetically connected to the magnetic adsorption ring 7. The stability of the annular crystal removal brush 8 is ensured by the magnetic connection, so that the annular crystal removal brush 8 can move with the magnetic adsorption ring 7, and then when the transmission sleeve 5 drives the magnetic adsorption ring 7 to move in a forward spiral or a reverse spiral, the magnetic adsorption ring 7 can drive the annular crystal removal brush 8 to move in a forward spiral or a reverse spiral, thereby effectively removing the crystals on the inner wall of the horizontal drain pipe 4.

[0026] As a preferred implementation scheme in this embodiment, it needs to be further explained that the bidirectional drive mechanism includes a worm 9 and a bidirectional drive motor 10 that drives the worm 9 to rotate forward or reverse. An outer tube notch 601 is provided on the outer wall of one side of the outer tube 6. One side of the transmission sleeve 5 extends from the outer tube notch 601 to the outside of the outer tube 6. The transmission sleeve 5 is provided with turbine teeth meshing with the worm 9 on the outer wall. The cooperation mode between the worm 9 and the transmission sleeve 5 is a combination of a worm gear structure. The transmission mode is simple and stable, and the bidirectional rotation effect of the transmission sleeve 5 can also be guaranteed in a simple way.

[0027] As a preferred embodiment of this embodiment, it should be further explained that bearings are connected to both ends of the transmission sleeve 5. The inner ring of the bearing is connected to the transmission sleeve 5, and the outer ring of the bearing is connected to the mounting outer tube 6. The bearings can ensure a stable connection between the transmission sleeve 5 and the mounting outer tube 6, and at the same time, the rotation of each of the two will not be hindered. It should be noted that in practice, because the worm 9 is only in transmission connection with the transmission sleeve 5 at the location of the outer tube notch 601, multiple bearings can be provided between the transmission sleeve 5 and the mounting outer tube 6 to further strengthen the stable connection between the two. Of course, the portion of the transmission sleeve 5 on both sides of the outer tube notch 601 can also be directly used as the inner ring of the bearing, and the mounting outer tube 6 can be used as the outer ring of the bearing. The transmission sleeve 5 and the mounting outer tube 6 can be designed into a single bearing structure. All of the above implementation methods can be used, and there is no specific limitation in practice. Selection and adjustment can be made according to actual conditions.

[0028] As a preferred implementation scheme in this embodiment, it needs to be further explained that multiple horizontal drainage pipes 4 are passed through the left and right ends of the inside of the pavement body 2. Multiple horizontal drainage pipes 4 can achieve a better drainage effect. The worm 9 is engaged with the turbine teeth on the outer wall of all the transmission sleeves 5 located at the same end of the pavement body. Of course, in practice, it can also be considered according to the on-site conditions. If one worm 9 is not enough, two or more can be set without specific restrictions. The purpose is to use a small number of worms 9 to drive multiple transmission sleeves 5 to rotate as much as possible, thereby saving costs.

[0029] As a preferred implementation scheme in this embodiment, it needs to be further explained that the bidirectional drive motor 10 is installed at one end of the worm 9, and the other end of the worm 9 is installed on a bearing seat. The bearing seat can enhance the stability of the worm 9 without affecting the rotation of the worm 9.

[0030] As a preferred implementation scheme in this embodiment, it needs to be further explained that the annular crystal removal brush 8 includes a connecting ring 801, a connecting rod 802 and a plurality of crystal removal brushes magnetically connected to the magnetic adsorption ring 7. All the crystal removal brushes are distributed in an annular shape. During the rotation and movement of the annular structure composed of the crystal removal brushes, the crystals on the inner wall of the horizontal drain pipe 4 are removed. The connecting ring 801 is arranged at the central axis of the horizontal drain pipe 4, and each crystal removal brush is connected to the connecting ring 801 through the connecting rod 802, ensuring that all the crystal removal brushes can move synchronously and be controlled by the magnetic adsorption ring 7.

[0031] As a preferred implementation scheme in this embodiment, it needs to be further explained that the crystal removal brush includes a first permanent magnet 803 and a stainless steel jacket 804 wrapped around the first permanent magnet 803. The structure of the stainless steel jacket 804 is stable and not easy to rust, which can ensure the service life. The first permanent magnet 803 is magnetically connected to the magnetic adsorption ring 7, and the connecting ring 801 and the connecting rod 802 are both made of stainless steel integrally formed with the stainless steel jacket 804 to ensure the stability and service life of the overall structure.

[0032] As a preferred implementation scheme in this embodiment, it needs to be further explained that the magnetic attraction ring 7 includes an externally threaded sleeve 701 and a plurality of second permanent magnets 702 wrapped in the externally threaded sleeve 701. The externally threaded sleeve 701 is threadedly connected to the inner wall of the transmission sleeve 5. Each first permanent magnet 803 is magnetically connected to a second permanent magnet 702. It is not necessary to use permanent magnets as a whole, thereby ensuring the stability of the magnetic attraction ring 7 and avoiding wear caused by the second permanent magnet 702 during movement.

[0033] As a preferred implementation scheme in this embodiment, it needs to be further explained that both ends of the stainless steel jacket 804 are ice-shoveling portions whose thickness gradually becomes thinner from the middle of the stainless steel jacket 804 to the two ends. This can make it easier for the stainless steel jacket 804 to shovel ice, thereby reducing the resistance when shoveling ice, and at the same time ensure the control effect of the magnetic adsorption ring 7 on the annular crystal scraping brush 8.

[0034] As a preferred implementation scheme in this embodiment, it needs to be further explained that both ends of the horizontal drain pipe 4 are provided with a baffle rod, which can be detachably connected to the mounting outer tube 6 to prevent the impact force on the annular crystal removal brush 8 from breaking through the magnetic attraction force of the magnetic adsorption ring 7 on the annular crystal removal brush 8 when the water volume is too large. After the drainage is completed, the magnetic adsorption ring 7 can also be moved, and then the annular crystal removal brush 8 can be simply adjusted to ensure the magnetic control effect of the magnetic adsorption ring 7 on the annular crystal removal brush 8 again.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
