A pipeline antifreeze protection structure for water diversion project

Abstract

The invention relates to the technical field of antifreeze for outlet risers of a Yellow River drip irrigation project, and discloses an antifreeze protection structure for pipes of a water diversion project. The invention solves the problem that most vertical pipes are pulled up by frost heave when soil layers freeze in winter, causing the vertical pipes to be disconnected from underground pipes and requiring annual maintenance, resulting in waste of resources.

Description

Technical Field

[0001] This invention relates to the field of antifreeze technology for water outlet risers in Yellow River drip irrigation projects, and particularly to an antifreeze protection structure for water diversion projects. Background Technology

[0002] The high-standard farmland construction project vigorously promotes in-depth water-saving measures, implements the Yellow River drip irrigation water-saving project, introduces Yellow River water into field reservoirs, and then irrigates crops through water pumps and water pipelines at all levels. The main and branch water pipelines are buried in the underground soil layer, and the outlet valves are connected to the underground water pipelines through vertical pipes.

[0003] A Chinese patent with publication number CN220957157U discloses a water pipe antifreeze protection structure, including a water pipe, an insulation sleeve fitted on the outside of the water pipe, an opening at the upper end of the insulation sleeve, an upper retaining sleeve fitted on the outside of the insulation sleeve, a high-temperature resistant protective shell fastened and fused to the outside of the upper retaining sleeve, an installation groove provided inside the upper retaining sleeve, a screw installed inside the installation groove, and a lower retaining sleeve fitted on the outside of the insulation sleeve.

[0004] However, the above-mentioned device has the following problems:

[0005] The soil frosts and heaves in winter, pulling most of the vertical pipes out of the ground and causing them to break off from the underground pipelines. This requires annual maintenance and results in a waste of resources.

[0006] Therefore, a pipe antifreeze protection structure for water diversion projects is needed to solve this problem. Summary of the Invention

[0007] In order to solve all or part of the above problems, the present invention aims to provide a pipeline antifreeze protection structure for water diversion projects, so as to solve the problem that the soil freezes and heaves in winter, most of the vertical pipes are pulled up by the freeze and heave, causing the vertical pipes to be disconnected from the underground pipelines, and the resources are wasted due to annual maintenance.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a pipeline antifreeze protection structure for a water diversion project, comprising a buried pipeline, a vertical riser installed at one end of the buried pipeline, an insulated pipeline installed on the outside of the buried pipeline, a guide component installed on the outside of the vertical riser, an energizing component installed inside the guide component, a drive end of the energizing component passing through one side of the guide component, an antifreeze expansion tube slidably installed on the outside of the guide component, the lower end of the antifreeze expansion tube slidably passing through the insulated pipeline, and a heating component installed on the antifreeze expansion tube;

[0009] Moisture accumulates and freezes in the soil around the anti-freeze tube. The frost heave force of the soil causes the anti-freeze tube to move upward, which in turn moves the input end of the heating component upward until the drive end of the energizing component connects with the input end of the heating component. The heating component then turns on to heat the inner wall of the anti-freeze tube, which increases the friction between the outer side of the anti-freeze tube and the soil. This causes the guide component to reset the anti-freeze tube.

[0010] Furthermore, the guiding assembly includes a guiding tube with multiple guiding grooves, and multiple guiding plates are installed on the inner wall of the anti-freeze expansion tube, with the guiding plates and guiding grooves being slidably connected.

[0011] When the soil layer experiences frost heave and pulls out force, the anti-frost heave pipe is subjected to an upward lift force and moves upward, causing the guide plate to slide upward along the guide groove. The anti-frost heave pipe takes the place of the guide pipe in being affected by frost heave, thus protecting the vertical pipe inside the guide pipe from the frost heave pull force and avoiding economic losses caused by soil frost heave damage to the pipeline in spring.

[0012] Furthermore, a limit ring is installed on the anti-freeze tube, a fixing tube is installed at the upper end of the guide tube, a fixing groove is opened on the outside of the fixing tube, a spring is sleeved on the fixing tube, the spring is located in the fixing groove, the upper end of the spring is fixedly connected to the lower side of the limit ring, and the lower end of the spring is fixedly connected to the lower end of the fixing tube.

[0013] The anti-frost heave tube moves upward due to the frost heave force, which in turn moves the limiting ring, causing the spring to move upward. After the ice crystals in the soil melt, the frost heave force disappears, and the downward pull of the spring causes the anti-frost heave tube to move downward, thus causing the anti-frost heave tube to return to its original position.

[0014] Furthermore, the distance between the guide grooves symmetrically located on both sides of the guide tube is greater than the outer diameter of the fixed tube.

[0015] When the guide plate moves upward along the guide groove, it will not cause the fixed tube and spring to move upward.

[0016] Furthermore, a conductive sheet is installed through the middle of the guide plate, and one end of the conductive sheet is electrically connected to the input end of the heating component.

[0017] Furthermore, the power-conducting component includes a ring-shaped battery, a cavity is formed inside the guide tube, the ring-shaped battery is located inside the cavity, a conductive block is installed on the upper side of the ring-shaped battery, a conductive plate is installed on the outer side of the conductive block, a connecting groove is formed on the guide tube, the connecting groove is located on one side of the guide groove, and the conductive plate is located inside the connecting groove.

[0018] The anti-freezing expansion tube moves upward due to the frost expansion force, which in turn drives the guide plate to move upward along the guide groove. The conductive sheet continues to move upward until it contacts the conductive plate. The conductive sheet and the conductive plate electrically connect the input end of the ring battery and the heating component. The ring battery continues to discharge, causing the output end of the heating component to start heating the area around the anti-freezing expansion tube, thus melting the ice crystals.

[0019] Furthermore, both the guide tube and the guide plate are components made of plastic.

[0020] The guide tube and guide plate are non-conductive, preventing short circuits during the connection of the conductive sheet and conductive plate.

[0021] Furthermore, the heating assembly includes a heating element mounted on an anti-freeze expansion tube, and a heat-conducting pipe is provided on one side of the heating element, which is also mounted on the anti-freeze expansion tube.

[0022] After the conductive sheet and the conductive plate come into contact, electrical energy is input to the heating element, which begins to heat up. The heat emitted fills the heat pipe, which heats the soil around the anti-frost heave pipe, melting the ice crystals that have condensed in the soil and mitigating the impact of frost heave on the anti-frost heave pipe.

[0023] Furthermore, the heating element is provided in four parts, and all four heat conduction tubes are installed on the outside of the anti-freeze expansion tube.

[0024] Furthermore, a heating element is provided and installed on the inner wall of the antifreeze expansion tube, a heat-conducting pipe is provided on one side of the heating element, and a wall cavity is opened inside the antifreeze expansion tube, with the heat-conducting pipe spirally arranged inside the wall cavity.

[0025] The heat generated by the heating element spirals and fills the heat-conducting pipe, raising the temperature inside the wall cavity. This melts the ice crystals that have condensed in the soil around the anti-freezing pipe, reducing the impact of frost heave on the anti-freezing pipe.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] This invention proposes a pipe antifreeze protection structure for water diversion projects. Moisture accumulates and freezes in the soil around the antifreeze expansion pipe. The frost heave force of the soil causes the antifreeze expansion pipe to move upwards, thereby driving the input end of the heating component upwards until the driving end of the energizing component connects with the input end of the heating component. The heating component then activates to heat the inner wall of the antifreeze expansion pipe, melting the ice crystals in the soil. This increases the friction between the outer side of the antifreeze expansion pipe and the soil, causing the guiding component to reset the antifreeze expansion pipe. The antifreeze expansion pipe, instead of the vertical pipe, is subjected to the upward lifting effect of frost heave. Attached Figure Description

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 are within the scope of protection of the present invention.

[0038] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings.

[0039] like Figures 1-4As shown, a pipe antifreeze protection structure for a water diversion project includes a buried pipe 1, a vertical riser 2 installed at one end of the buried pipe 1, an insulated pipe 3 installed on the outside of the buried pipe 1, a guide assembly 4 installed on the outside of the vertical riser 2, an energizing assembly 5 installed inside the guide assembly 4, a drive end of the energizing assembly 5 penetrating through one side of the guide assembly 4, an antifreeze expansion tube 6 slidably installed on the outside of the guide assembly 4, the lower end of the antifreeze expansion tube 6 slidably penetrating through the insulated pipe 3, and a heating element installed on the antifreeze expansion tube 6. Component 7; Moisture accumulates and freezes in the soil around the anti-freeze tube 6. The frost heave force of the soil causes the anti-freeze tube 6 to move upward, thereby driving the input end of the heating component 7 to move upward until the driving end of the energizing component 5 and the input end of the heating component 7 are connected. The heating component 7 turns on to heat the inner wall of the anti-freeze tube 6, melting the ice crystals in the soil. This increases the friction between the outer side of the anti-freeze tube 6 and the soil, causing the guide component 4 to reset the anti-freeze tube 6. The anti-freeze tube 6 replaces the vertical pipe 2 and is affected by the frost heave.

[0040] like Figures 3-4 As shown, the guiding assembly 4 includes a guide tube 41 with multiple guide grooves 411. Multiple guide plates 61 are installed on the inner wall of the anti-frost heave pipe 6. The guide plates 61 and guide grooves 411 are slidably connected. When the soil layer experiences pull-out force due to frost heave, the anti-frost heave pipe 6 experiences upward lift and moves upward, causing the guide plates 61 to slide upward along the guide grooves 411. The anti-frost heave pipe 6 replaces the guide tube 41 in being affected by frost heave, thus protecting the vertical riser 2 inside the guide tube 41 from the pull-out force of frost heave. This avoids economic losses caused by soil frost heave damage to the pipeline in spring. A limit ring 62 is installed on the anti-frost heave pipe 6, and a fixing pipe 42 is installed at the upper end of the guide tube 41. A fixing ring is located on the outer side of the fixing pipe 42. A spring 43 is fitted onto the fixed tube 42 in the groove 421. The upper end of the spring 43 is fixedly connected to the lower side of the limiting ring 62, and the lower end of the spring 43 is fixedly connected to the lower end of the fixed tube 42. The anti-frost heave tube 6 moves upward due to the frost heave force, thereby driving the limiting ring 62 to move, which in turn drives the spring 43 to move upward. After the ice crystals in the soil melt, the frost heave force disappears, and the downward pull of the spring 43 drives the anti-frost heave tube 6 to move downward, causing the anti-frost heave tube 6 to return to its original position. The distance between the guide grooves 411 symmetrically located on both sides of the guide tube 41 is greater than the outer diameter of the fixed tube 42. When the guide plate 61 moves upward along the guide groove 411, it will not drive the fixed tube 42 and the spring 43 to move upward.

[0041] like Figures 4-5As shown, a conductive sheet 611 is installed through the middle of the guide plate 61. One end of the conductive sheet 611 is electrically connected to the input end of the heating component 7. The power-conducting component 5 includes a ring battery 51. A cavity 412 is opened inside the guide tube 41, and the ring battery 51 is located in the cavity 412. A conductive block 52 is installed on the upper side of the ring battery 51, and a conductive plate 53 is installed on the outer side of the conductive block 52. A connecting groove 413 is opened on the guide tube 41, and the connecting groove 413 is located on one side of the guide groove 411. The conductive plate 53 is located in the connecting groove 413. The anti-freezing tube 6 moves upward due to the frost heave force. This causes the guide plate 61 to move upward along the guide groove 411, and the conductive sheet 611 continues to move upward until it contacts the conductive plate 53. The conductive sheet 611 and the conductive plate 53 electrically connect the ring battery 51 and the input end of the heating component 7. The ring battery 51 continues to discharge, causing the output end of the heating component 7 to start heating the area around the antifreeze tube 6, thus melting the ice crystals. The guide tube 41 and the guide plate 61 are both made of plastic and are non-conductive, preventing short circuits from occurring during the connection of the conductive sheet 611 and the conductive plate 53.

[0042] like Figures 4-5 As shown, in order to heat the inner wall of the anti-frost heave tube 6, melt the ice crystals between the soil, and increase the friction between the outer side of the anti-frost heave tube 6 and the soil, so as to cause the guide component 4 to reset the anti-frost heave tube 6, the heating component 7 is provided in Embodiment 1. The heating component 7 includes a heating element 71, which is installed on the anti-frost heave tube 6. A heat conduction pipe 72 is provided on one side of the heating element 71. The heat conduction pipe 72 is installed on the anti-frost heave tube 6. There are four heating elements 71. All four heat conduction pipes 72 are installed on the outer side of the anti-frost heave tube 6. After the conductive sheet 611 and the conductive plate 53 come into contact, electrical energy is input to the heating element 71. The heating element 71 starts to heat up, and the heat emitted fills the heat conduction pipe 72. The heat conduction pipe 72 heats the soil around the anti-frost heave tube 6, melts the ice crystals that have condensed between the soil, and alleviates the impact of frost heave force on the anti-frost heave tube 6.

[0043] like Figures 6-8 As shown, the heating assembly 7 is provided in Embodiment 2. The heating assembly 7 includes a heating element 71, which is installed on the inner wall of the anti-freezing expansion tube 6. A heat-conducting pipe 72 is provided on one side of the heating element 71. A wall cavity 63 is opened inside the anti-freezing expansion tube 6. The heat-conducting pipe 72 is spirally arranged in the wall cavity 63. The heat generated by the heating element 71 fills the spiral heat-conducting pipe 72, raising the temperature in the wall cavity 63. This melts the ice crystals that condense in the soil around the anti-freezing expansion tube 6, reducing the frost heave force that causes the anti-freezing expansion tube 6 to rise.
