Description

Technical Field

[0001] The invention relates to the technical field of thermal insulation pipes, in particular to a prefabricated direct-buried thermal insulation pipe. Background Art

[0002] Insulated pipe is the abbreviation of insulated pipe. Insulated pipe is used for the transportation of liquid, gas and other media. Prefabricated direct buried insulated pipe is mainly used for regional heating external network pipeline. With the promotion of centralized heating in the country, its usage is increasing and its application scope is becoming wider and wider. Prefabricated direct buried insulated pipe has many advantages such as waterproof, good anti-corrosion performance, saving investment, shortening construction period and low maintenance cost.

[0003] At present, during the pre-buried process of the insulation pipe, the insulation pipe is often installed in the pre-buried tunnel, and then buried after the sealing is tested. However, during the installation of the insulation pipe, mud is easy to adhere to the pipe components, which is easy to affect the subsequent pipe connection and sealing detection, making the pre-buried operation effect of the insulation pipe worse. At the same time, since the insulation pipe is pre-buried underground, it is relatively humid, which is easy to cause aging or corrosion to the pipe components, reducing its service life, thereby affecting the insulation effect of the insulation pipe.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figure 1-Figure 11 As shown, a prefabricated direct-buried thermal insulation pipe includes a pipe body 1, a pair of mounting flanges 2 are sleeved on the outer wall of the pipe body 1, and a plurality of mounting holes are drilled on the pair of mounting flanges 2, a plurality of supporting sleeves 3 are sleeved on the outer wall of the pipe body 1, and a pair of connecting side frames 4 are fixedly connected between the outer walls of the plurality of supporting sleeves 3, lateral supporting mechanisms 5 are provided between the plurality of supporting sleeves 3, and a longitudinal supporting mechanism 8 and a movable heat release mechanism 10 are respectively provided inside the pair of connecting side frames 4.

[0035] During use of the present solution, multiple support sleeves 3 can contact the bottom of the pre-buried pit to support the pipe body 1, and a pair of mounting flanges 2 are connected and fixed to two adjacent pipe bodies 1 through multiple mounting holes, so as to drive multiple pipe bodies 1 to be connected and fixed to each other.

[0036] like Figure 1-Figure 2 As shown, the lateral support mechanism 5 includes a plurality of pairs of screw rods 501, the ends of the plurality of pairs of screw rods 501 that are far away from each other are rotatably connected to the inner wall of the support sleeve frame 3 through bearings, the ends of the plurality of pairs of screw rods 501 that are close to each other are fixedly connected to a first bevel gear 502, and a second bevel gear 503 is meshedly connected between the outer walls of a pair of first bevel gears 502, a rotating rod 508 is fixedly connected between the outer walls of the plurality of second bevel gears 503, and the outer walls of the rotating rod 508 are rotatably connected to the plurality of support sleeve frames 3 through bearings, and the outer walls of the plurality of pairs of screw rods 501 are A threaded sleeve 504 is threadedly connected, and a movable long plate 505 is fixedly connected to the top of the threaded sleeve 504. Rectangular through holes are drilled on the inner walls of the front and rear ends of the multiple support sleeve frames 3, and the ends away from each other of a pair of movable long plates 505 pass through the rectangular through holes and are fixedly connected to the side support plates 506. A pair of toggle plates 507 are sleeved on the outer wall of the rotating rod 508, and a plurality of rotating collision mechanisms 6 are sleeved on the outer wall of the rotating rod 508. A blowing mechanism 7 is provided between the outer walls of the two pairs of screw rods 501 located on the outside and the outer wall of the pipe body 1.

[0037] During use of the present solution, the rotating dial 507 drives the rotating rod 508 to rotate, and the rotating rod 508 drives the multiple second bevel gears 503 to rotate, so that the second bevel gears 503 drive a pair of first bevel gears 502 meshing therewith to rotate, prompting multiple pairs of screw rods 501 to rotate, driving multiple pairs of threaded sleeve blocks 504 to move away from each other, and pushing a pair of side support plates 506 to move away from each other by moving the long plate 505 until they contact the pit wall of the embedded pit, thereby providing lateral support and reinforcement, ensuring the lateral support strength of the pipeline body 1, keeping the pipeline body 1 stable, and not easily shaken by external factors during subsequent use.

[0038] like Figure 1-Figure 3 As shown, multiple rotating collision mechanisms 6 all include a rotating cylinder 601 which is sleeved on the outer wall of the rotating rod 508, the interior of the rotating cylinder 601 is slidably connected with a piston plate 603, and the bottom end of the piston plate 603 is fixedly connected with a collision protrusion 602, a circular hole is drilled at the inner bottom end of the rotating cylinder 601, and the bottom end of the collision protrusion 602 passes through the circular hole and extends to its bottom, the bottom end of the collision protrusion 602 contacts the outer wall of the pipe body 1, and an elastic ring 604 is fixedly connected between the top of the piston plate 603 and the inner top of the rotating cylinder 601.

[0039] During use of the present solution, when the pipe body 1 is placed inside the embedded pit, dirt is easily adhered to its surface. Then, after a pair of mounting flanges 2 drive multiple adjacent pipe bodies 1 to be connected and fixed, a trial run is required to perform a sealing test. In order to avoid interference and influence of dirt on the connection and sealing test, the rotating cylinder 601 is driven to rotate by the rotation of the rotating rod 508, so that the rotating cylinder 601 drives the collision protrusion 602 to rotate. The collision protrusion 602 contacts and collides with the outer wall of the pipe body 1 during the rotation, and moves toward the inside of the rotating cylinder 601 under the elastic displacement of the piston plate 603 and the elastic ring 604 until it is rotated and separated from the outer wall of the pipe body 1. The collision protrusion 602 is repeatedly rotated so that the collision protrusion 602 repeatedly contacts, collides and separates from the outer wall of the pipe body 1 during the rotation, generating vibration, causing the dirt attached to the outer walls of the pipe body 1 and the pair of mounting flanges 2 to fall off under the action of the vibration.

[0040] like Figure 1 and Figure 4-Figure 5As shown, a pair of blowing mechanisms 7 each include an annular frame 701 sleeved on the outer wall of the pipe body 1, an annular elastic airbag 702 is fixedly connected to the inner wall of the annular frame 701, and a plurality of blowing filter tubes 703 are fixedly connected between the annular elastic airbag 702 and the outer wall of the annular frame 701, and the plurality of blowing filter tubes 703 respectively correspond to the plurality of mounting holes, an annular opening is bored at one end of the annular frame 701 close to the supporting sleeve frame 3, and an annular extrusion plate 704 in close contact with the annular opening is provided on the inner wall of the annular opening, and an end of the annular extrusion plate 704 away from the supporting sleeve frame 3 is fixedly connected to one end of the annular elastic airbag 702, a convex plate 706 is sleeved on the outer wall of a pair of screw rods 501 located on the outside, and a movable convex rod 705 in contact with the convex plate 706 is provided at one end thereof, a through hole is bored at one end of the supporting sleeve frame 3 close to the annular extrusion plate 704, and one end of the movable convex rod 705 passes through the through hole and is fixedly connected to one end of the annular extrusion plate 704 close to the supporting sleeve frame 3.

[0041] During the use of this solution, when the pipe body 1 is placed inside the embedded pit, not only the surfaces of the pipe body 1 and the mounting flange 2 are prone to be adhered to mud, but also the multiple mounting holes on a pair of mounting flanges 2 are prone to residual mud. Therefore, when the two pairs of screw rods 501 located on the outside rotate, the two pairs of convex plates 706 are driven to rotate, so that during the rotation process, the convex plates 706 use the convex ends to repeatedly squeeze the movable convex rods 705 and the annular extrusion plates 704 to move toward the inside of the annular frame 701, and repeatedly squeeze the air inside the annular elastic airbag 702 through multiple blowing filter tubes 703 to blow to the multiple mounting holes on a pair of mounting flanges 2, so that the mud inside the mounting holes is blown away, the cleanliness of the inside of the mounting holes is maintained, the mud is fully and comprehensively cleaned, and the mud cleaning effect is enhanced.

[0042] like Figure 1 and Figure 6-Figure 7As shown, a pair of longitudinal support mechanisms 8 each include a bidirectional screw 801 rotatably connected to the inner wall of the connecting side frame 4, the top of the bidirectional screw 801 is fixedly connected to a hand crank 806, the outer wall of the bidirectional screw 801 is threadedly connected to a pair of threaded sleeves 803, and the top of the threaded sleeve 803 located at the top is fixedly connected to a plurality of top plates 802, the inner top of the connecting side frame 4 is opened with a plurality of upper openings, and the tops of the plurality of top plates 802 all pass through the upper openings and are fixedly connected to a U-shaped support plate 805, and the inner walls of the plurality of U-shaped support plates 805 are respectively connected to a plurality of movable plates located on one side. The outer wall of the movable long plate 505 is in contact, and a moisture-proof release mechanism 9 is provided between one end of the threaded sleeve 803 located at the top and the interior of the multiple support sleeve frames 3, and the bottom end of the threaded sleeve 803 located at the bottom is fixedly connected to a plurality of plug rods 804, and the bottom end of the plug rod 804 is set in a pointed cone shape, and a plurality of lower circular holes are drilled at the inner bottom end of the connecting side frame 4, and the bottom ends of the plurality of plug rods 804 all pass through the lower circular holes and extend to the bottom thereof, and the inner walls of the plurality of lower circular holes are fixedly connected to circular scrapers 807, and the inner wall of the circular scraper 807 is in close contact with the outer wall of the plug rod 804.

[0043] During use of the present solution, rotating the hand crank 806 drives the bidirectional screw 801 to rotate, causing a pair of threaded sleeves 803 to move away from each other. At this time, the top threaded sleeve 803 drives multiple top plates 802 and U-shaped support plates 805 to move upward until they contact the outer wall of the movable long plate 505, thereby providing auxiliary support for the movable long plate 505 and reinforcing the lateral support strength of the movable long plate 505 and the side support plate 506. The bottom threaded sleeve 803 drives multiple insertion rods 804 to move downward, and uses its sharp bottom end to penetrate into the soil, maintains a tight connection with the soil, and performs longitudinal support and reinforcement to ensure the longitudinal support strength of the pipeline body 1, so that the pipeline body 1 remains stable and is not easily shaken by external factors during subsequent use. When problems occur in the subsequent pipeline body 1 and it needs to be disassembled for maintenance, the circular scraper 807 scrapes the surfaces of the multiple insertion rods 804 moving upward to remove the soil attached to their surfaces and prevent them from entering the connecting side frame 4.

[0044] like Figure 1 and Figure 8-Figure 9As shown, a pair of moisture-proof release mechanisms 9 each include a first single-sided magnet block 901, one end of the threaded sleeve plate 803 located at the top is fixedly connected to one end of the first single-sided magnet block 901, a plurality of receiving holes are opened between the connecting side frame 4 and the plurality of supporting sleeve frames 3, and the interiors of the plurality of receiving holes are slidably connected to the second single-sided magnet block 902, the first single-sided magnet block 901 and the second single-sided magnet block 902 are close to each other and repel each other, and the ends of the plurality of second single-sided magnet blocks 902 away from the first single-sided magnet block 901 are fixedly connected to push-pull Rod 903, the inner walls of multiple support sleeves 3 are fixedly connected with storage boxes 904, and the inner bottom ends of the storage boxes 904 and the multiple support sleeves 3 are provided with multiple moisture-proof balls 907, the outer wall of the storage box 904 is opened with a pair of sealing openings, and an I-shaped sealing plate 905 is arranged between the inner walls of the pair of sealing openings, one end of the I-shaped sealing plate 905 is fixedly connected to one end of the push-pull rod 903 away from the second single-sided magnet block 902, and a pair of spring sheets 906 are fixedly connected between one end of the I-shaped sealing plate 905 and the inner wall of the support sleeve 3.

[0045] During use of the present solution, when the top threaded sleeve 803 moves upward, it drives the first single-sided magnet block 901 to move upward synchronously. When the U-shaped support plate 805 contacts the movable long plate 505, the first single-sided magnet block 901 moves to correspond to the plurality of second single-sided magnet blocks 902, and uses the magnetic repulsion force to drive the second single-sided magnet blocks 902 to move toward the storage box 904, away from the accommodating hole, and push the I-shaped sealing plate 905 to move synchronously, causing some moisture-proof balls 907 to fall downward to the bottom end of the support sleeve frame 3 under the push and squeeze of the I-shaped sealing plate 905, so that the plurality of moisture-proof balls 907 are respectively distributed in the support sleeve frame 3 and the storage box 904, so as to facilitate moisture absorption and moisture-proof treatment at multiple height positions, so that the moisture absorption and moisture-proof range is wider, the moisture-proof effect is enhanced, and the influence of humidity of the pipeline body 1 buried underground is reduced.

[0046] like Figure 1 and Figure 10-11As shown, a pair of mobile heat release mechanisms 10 each include a pair of built-in straight rods 1001, both ends of the pair of built-in straight rods 1001 are fixedly connected to the inner wall of the connecting side frame 4, and the outer wall of the pair of built-in straight rods 1001 is sleeved with a mobile sleeve block 1002, the top of the pair of mobile sleeve blocks 1002 is fixedly connected to a thermal insulation and magnetic insulation frame 1003, and the inner top of the thermal insulation and magnetic insulation frame 1003 is fixedly connected to a magnetic temperature change block 1004, the front and rear ends of the pair of mobile sleeve blocks 1002 are fixedly connected to a deformation memory telescopic rod 1005, and the top of the pair of deformation memory telescopic rods 1005 is fixedly connected to a thermal insulation and magnetic insulation plate 1006, a pair of fitting openings are opened at the bottom end of the thermal insulation and magnetic insulation frame 1003, and the outer wall of the thermal insulation and magnetic insulation plate 1006 is in close contact with the inner wall of the fitting opening, and the pair of built-in straight rods 1001 The outer walls are all sleeved with deformation memory springs 1007, and the two ends of the deformation memory springs 1007 are respectively fixedly connected to one end of the movable sleeve block 1002 and the inner wall of the connecting side frame 4, and a fan mechanism 11 is provided at the top of the thermal insulation and magnetic insulation frame 1003 located on the outside, and the outer wall of the thermal insulation and magnetic insulation frame 1003 and the bottom end of a pair of thermal insulation and magnetic insulation plates 1006 are both provided with a thermal insulation layer, and the inner wall of the thermal insulation and magnetic insulation frame 1003 and the top of a pair of thermal insulation and magnetic insulation plates 1006 are both provided with a magnetic insulation layer, the initial states of the two pairs of deformation memory telescopic rods 1005 are both in a contracted state, the initial states of the pair of deformation memory springs 1007 are both in a stretched state, and the pair of fan mechanisms 11 include a connecting straight plate 1101 fixedly connected to the top of the thermal insulation and magnetic insulation frame 1003, and one end of the connecting straight plate 1101 is fixedly connected to a horizontal fan 1102.

[0047] During the use of this solution, since the pipeline body 1 is pre-buried in the ground, it is very humid. In severe cases, water seepage is likely to occur. At this time, the deformation memory telescopic rod 1005 made of water-induced shape memory polymer material is deformed when it encounters water, and is converted from a contracted state to an extended state, pushing the thermal insulation and magnetic insulation plate 1006 to move upward, causing the thermal insulation and magnetic insulation frame 1003 and a pair of thermal insulation and magnetic insulation plates 1006 in a sealed closed state to separate, and the thermal insulation and magnetic insulation effect disappears. The magnetic temperature variable block 1004 is made of magnetic refrigeration material. Based on the magnetocaloric effect, under the influence of the external magnetic field of the first single-sided magnet block 901 and the second single-sided magnet block 902, the magnetic moment of the magnetic temperature variable block 1004 changes from disorder to order along the magnetic field direction, and the magnetic entropy decreases. According to the knowledge of thermodynamics, at this time, the magnetic temperature variable block 1004 releases heat outward, causing the internal temperature of the connecting side frame 4 to rise, driving the deformation memory spring 1007 made of shape memory alloy material to deform and shrink due to heat, pulling the movable sleeve block 1002 and the magnetic temperature variable block 1 004 moves horizontally along the built-in straight rod 1001 to release heat in all directions. At the same time, the horizontal fan 1102 moves synchronously with the outer movable sleeve block 1002, fanning the hot air inside the connecting side frame 4 to flow into the multiple support sleeve frames 3 through multiple accommodating holes, drying the moisture inside the support sleeve frame 3 and the moisture-proof ball 907, and avoiding the moisture-proof ball 907 from being saturated with moisture, so as to facilitate subsequent moisture absorption and moisture-proof work, and at the same time avoid moisture from corroding and aging the support sleeve frame 3 and its internal structural components, thereby ensuring the service life of the pipeline components and avoiding affecting the insulation effect of the insulation pipe. After the moisture is dried and removed, the deformation memory telescopic rod 1005 loses the influence of water and shrinks and resets, driving the thermal insulation and magnetic insulation frame 1003 and a pair of thermal insulation and magnetic insulation plates 1006 to seal and close, and insulate and magnetically insulate the magnetic temperature change block 1004. Then, after the temperature drops, the deformation memory spring 1007 also extends and resets, driving the movable sleeve block 1002 and the magnetic temperature change block 1004 to reset.

[0048] The present invention provides a prefabricated direct-buried thermal insulation pipe with the following working principle: after the pipe body 1 is placed inside the pre-buried pit, the toggle plate 507 is rotated first to drive the rotating rod 508 to rotate, and the rotating rod 508 drives multiple second bevel gears 503 to rotate, so that the second bevel gears 503 drive a pair of first bevel gears 502 meshing therewith to rotate, prompting multiple pairs of screw rods 501 to rotate, driving multiple pairs of threaded sleeve blocks 504 to move away from each other, and pushing a pair of side support plates 506 to move away from each other by moving the long plate 505 until they contact the pit wall of the pre-buried pit for lateral support reinforcement, and at the same time, when the rotating rod 508 rotates, it drives the rotating cylinder 601 to rotate, so that the rotating cylinder 601 drives the collision convex rod 602 to rotate, and the collision convex rod 602 is rotated with The outer wall of the pipe body 1 contacts and collides with it, and under the elastic displacement of the piston plate 603 and the elastic ring 604, it moves toward the inside of the rotating cylinder 601 until it rotates and separates from the outer wall of the pipe body 1. This repeated rotation causes the collision convex rod 602 to repeatedly contact, collide and separate from the outer wall of the pipe body 1 during the rotation process, generating vibration, causing the soil attached to the outer walls of the pipe body 1 and a pair of mounting flanges 2 to fall off under the action of vibration. When the two pairs of screw rods 501 located on the outside rotate, the two pairs of convex plates 706 are driven to rotate, so that the convex plates 706 repeatedly squeeze the movable convex rod 705 and the annular extrusion plate 704 to move toward the inside of the annular frame 701 during the rotation process, repeatedly squeezing the air inside the annular elastic airbag 702 through multiple blowing filter tubes 70 3 blows toward the multiple mounting holes on a pair of mounting flanges 2 to blow away the soil inside the mounting holes, then, the rotating hand crank disk 806 drives the bidirectional screw 801 to rotate, so that the pair of threaded sleeves 803 move away from each other, at this time, the top threaded sleeve 803 drives the multiple top plates 802 and the U-shaped support plate 805 to move upward until they contact the outer wall of the movable long plate 505, so as to provide auxiliary support for the movable long plate 505, while the bottom threaded sleeve 803 drives the multiple insertion rods 804 to move downward, and uses its sharp bottom end to penetrate into the soil, maintains a tight connection with the soil, and performs longitudinal support and reinforcement, and when the top threaded sleeve 803 moves upward, it drives the first single-sided magnet block 901 to move upward synchronously, when the U-shaped support plate 805 is moved upward, 05 contacts with the movable long plate 505, the first single-sided magnet block 901 moves to correspond to the plurality of second single-sided magnet blocks 902, and uses the magnetic repulsion force to drive the second single-sided magnet blocks 902 to move in the direction of the storage box 904, away from the accommodating hole, and pushes the I-shaped sealing plate 905 to move synchronously, so that some moisture-proof balls 907 fall downward to the bottom end of the support sleeve frame 3 under the push and squeeze of the I-shaped sealing plate 905, so that the plurality of moisture-proof balls 907 are respectively distributed in the support sleeve frame 3 and the storage box 904. After the connection and fixation of the pipeline body 1 and the sealing test are completed, when it is put into use, the underground is seriously humid. When water seepage occurs, the deformation memory telescopic rod 1005 deforms and extends when it encounters water, pushing the thermal insulation and magnetic insulation plate 1006 to move upward.The temperature-insulating and magnetic-insulating frame 1003 and a pair of temperature-insulating and magnetic-insulating plates 1006 in the sealed closed state are separated, and the temperature-insulating and magnetic-insulating effect disappears, which causes the magnetic temperature-changing block 1004 to release heat under the influence of the external magnetic field of the first single-sided magnet block 901 and the second single-sided magnet block 902, so that the temperature inside the connecting side frame 4 rises, driving the deformation memory spring 1007 to deform and shrink due to heat, pulling the moving sleeve block 1002 and the magnetic temperature-changing block 1004 to move horizontally along the built-in straight rod 1001, and releasing heat in multiple directions. At the same time, the horizontal fan 1102 moves synchronously with the outer moving sleeve block 1002, fanning the hot air inside the connecting side frame 4 to flow through multiple accommodating holes to multiple support sleeve frames 3, drying the moisture inside the support sleeve frame 3 and the moisture-proof ball 907.
