Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of installation and locking technology, and more specifically, to a protective structure for a heating pipeline network. Background Technology

[0002] Heating pipe network, also known as heating pipeline, is a network of heating pipes that start from boiler rooms, direct-fired machine rooms, heating centers, etc., and run from heat sources to the heating inlets of buildings. Multiple heating pipes form a network.

[0003] According to a public disclosure of a heating pipeline insulation layer protection structure (publication number: CN218762157U), it includes an insulation shell, locking strips on both sides of the insulation shell, locking bolts at the upper and lower ends of the two locking strips, a sealing strip between the two locking strips, an insulation layer on the inner wall of the insulation shell, and an insulation layer on the inner wall of the insulation layer. This utility model greatly improves the insulation and sealing performance by utilizing the insulation layer and sealing strip, thereby greatly reducing the heat loss rate of the heating pipeline.

[0004] In the aforementioned application, the cooperation between the locking strip and the locking bolt assembly makes it difficult to solve the protection function of the heating pipe when it is transporting heat energy. Moreover, its complex structure leads to complicated installation and is inconvenient to install. Therefore, we propose a heating pipe network protection structure. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a heating pipeline protection structure, which solves the problem of inability to securely protect the pipeline in related technologies.

[0006] According to one aspect, at least one embodiment of this disclosure provides a heating pipe network protection structure, including an upper protective pipe, one end of which is fixedly connected to an upper disc, a lower protective pipe is provided at the bottom of the upper protective pipe, one end of which is fixedly connected to a lower disc, and a locking device is provided on the circumferential surface of the lower disc.

[0007] The locking device includes a lower support plate, the side of which is fixedly connected to the circumferential surface of the lower protective tube. A locking pin is fixedly connected to the top of the lower support plate. An annular groove is formed on the circumferential surface of the locking pin. A locking lug is provided on the inner side of the annular groove. A spring is fixedly connected to the side of the locking lug. A locking block is fixedly connected to the end of the spring away from the locking lug. A square box is locked onto the circumferential surface of the locking block. An upper support plate is fixedly connected to the bottom of the square box. The side of the upper support plate is fixedly connected to the circumferential surface of the upper protective tube.

[0008] For example, in a heating network protection structure provided in at least one embodiment of this disclosure, the structure further includes: a box cover is provided on the top of the box, a handle is fixedly connected to the side of the block, the handle is elliptical in shape, the box cover covers the through hole to prevent dust from entering, and the handle makes operation more convenient.

[0009] The diameter of the locking block is slightly larger than the diameter of the internal through hole of the square box. The bottom of the upper support plate has a through hole that is interconnected with the internal through hole of the square box. The purpose of this is to allow the lock lug to slide inside the through hole and the locking block to lock the internal through hole of the square box.

[0010] There are two upper and lower discs, which are symmetrical about each other along the central axis of the upper protective tube, so that they can be connected end to end and interconnected.

[0011] The circumferential surface of the annular groove is located on the displacement trajectory of the lock lug, and the circumferential surface of the lock lug is slidably connected to the inside of the square box, the purpose of which is to lock the lock lug with the lock pin.

[0012] According to another aspect, at least one embodiment of this disclosure also provides a heating pipe network protection structure, including a protective pipe. A protective device is provided on the inner circumferential surface of the lower protective pipe. The protective device includes an inflatable air cushion, which is fixedly connected to the inner circumferential surface of the lower protective pipe. An air inlet pipe is passed through and fixedly connected to the outer circumferential surface of the air cushion. A bend is fixedly connected to the end of the air inlet pipe away from the air cushion. An air delivery pipe is fixedly connected to the top of the bend. An air bladder is fixedly connected to the end of the air delivery pipe away from the bend. The bottom of the air bladder is fixedly connected to a lower support plate. The purpose of this structure is to protect the heating pipe.

[0013] For example, in a heating pipe network protection structure provided in at least one embodiment of this disclosure, the circumferential surface of the air inlet pipe is connected to the circumferential surface of the lower protective pipe through and fixedly connected, and the circumferential surface of the air delivery pipe is connected to the side of the lower support plate through and fixedly connected. The purpose of this is to reduce the amount of material used in the through structure.

[0014] A protective plate is fixedly connected to the top of the lower support plate, and a protective pad is fixedly connected to the circumferential surface of the upper protective tube. The width of the protective pad is slightly smaller than that of the upper protective tube, and its purpose is to provide safety protection. The protective plate limits the outward distance of the airbag.

[0015] The number of airbags and protective plates is two, and they are symmetrical to each other along the central axis of the lower protective pipe. The number of air supply pipes and bends is four, in pairs, to increase working efficiency and make it more stable.

[0016] The top of the airbag is located on the displacement trajectory of the bottom of the upper support plate, and the side of the protective plate is located on the displacement trajectory of the side of the airbag. The purpose of this is to compress the airbag to inflate the air cushion.

[0017] The beneficial effects of the embodiments disclosed herein are as follows:

[0018] 1. In this utility model, through the cooperation of components such as the lower support plate, locking pin, locking lug, and spring in the locking device, when the heating pipe needs protection, the heating pipe is placed into the upper protective tube, and the upper and lower protective tubes are connected. The locking pin enters the square box through the through hole at the bottom of the upper support plate. The annular groove on the circumference of the locking pin, through the locking block inside the square box, and the spring's rebound force, compresses the locking lug and locks it in place. At this time, the tightness of the locking lug can be adjusted by adjusting the depth of the locking block in the square box using the handle. When disassembly is required, simply pull out the locking lug using the handle to complete locking and disassembly. This solves the pain points of cumbersome installation and easy loosening of heating pipe protection devices, and is suitable for complex terrain and emergency repair scenarios.

[0019] 2. In this utility model, through the cooperation of components such as the inflatable air cushion, air inlet pipe, bend pipe and air bag in the protection device, when the upper protection pipe is connected to the lower protection pipe, the bottom of the upper support plate presses down on the air bag, forcing the gas inside the air bag to be transported through the air supply pipe and bend pipe to the air inlet pipe and finally enter the inflatable air cushion. After the gas is injected, the inflatable air cushion expands and tightly fits the outer wall of the heating pipe to form a buffer layer to absorb external impact. When the external pressure is released, the air bag returns to its original shape due to its elasticity, and the gas inside the inflatable air cushion flows back to the air bag through the air inlet pipe to realize the system reset, which is convenient and quick.

[0027] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0028] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0029] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0030] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0032] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] like Figures 1-5 As shown, a heating network protection structure according to an embodiment of the present disclosure is illustrated, including an upper protective pipe 1, an upper disc 2 fixedly connected to one end of the upper protective pipe 1, a lower protective pipe 3 provided at the bottom of the upper protective pipe 1, a lower disc 4 fixedly connected to one end of the lower protective pipe 3, and a locking device 5 provided on the circumferential surface of the lower disc 4.

[0034] The locking device 5 includes a lower support plate 501. The side of the lower support plate 501 is fixedly connected to the circumferential surface of the lower protective tube 3. A locking pin 502 is fixedly connected to the top of the lower support plate 501. An annular groove 503 is provided on the circumferential surface of the locking pin 502. A locking lug 504 is provided on the inner side of the annular groove 503. A spring 505 is fixedly connected to the side of the locking lug 504. A locking block 506 is fixedly connected to the end of the spring 505 away from the locking lug 504. A square box 507 is locked onto the circumferential surface of the locking block 506. An upper support plate 508 is fixedly connected to the bottom of the square box 507. The side of the upper support plate 508 is fixedly connected to the circumferential surface of the upper protective tube 1.

[0035] In some examples, the box 507 is also provided with a box cover 6 on the top, and a handle 7 is fixedly connected to the side of the block 506. The handle 7 is elliptical in shape. The box cover 6 covers the through hole to prevent dust from entering, and the handle 7 makes operation more convenient.

[0036] The diameter of the locking block 506 is slightly larger than the diameter of the internal through hole of the square box 507. The bottom of the upper support plate 508 has a through hole that is interconnected with the internal through hole of the square box 507. The purpose of this is to allow the locking pin 502 to slide inside the through hole.

[0037] There are two upper disks 2 and two lower disks 4. The upper disks 2 and 4 are symmetrical about each other along the central axis of the upper protective tube 1, so that they can be connected end to end and interconnected.

[0038] The circumferential surface of the annular groove 503 is located on the displacement trajectory of the locking lug 504. The circumferential surface of the locking lug 504 is slidably connected to the inside of the square box 507. The purpose of this is to lock the locking lug 504 with the locking pin 502.

[0039] For example, such as Figures 1-5As shown, when the heating pipe needs protection, the heating pipe is placed into the upper protective pipe 1, and the upper and lower protective pipes 3 are placed together. The locking pin 502 enters the square box 507 through the through hole at the bottom of the upper support plate 508. The annular groove 503 on the circumference of the locking pin 502, through the locking block 506 that is engaged inside the square box 507, is pressed into the locking lug 504 by the rebound force of the spring 505. At this time, the tightness of the locking lug 504 can be adjusted by adjusting the depth of the locking block 506 in the square box 507 using the handle 7. When disassembly is required, simply pull out the locking lug 504 using the handle 7 to complete the locking and disassembly.

[0040] like Figures 1-5 As shown, a heating pipe network protection structure is provided in another embodiment of this disclosure. It is largely the same as the above-described technical solution, so only the differences are described. A protection device 8 is provided on the inner circumferential surface of the lower protection pipe 3. The protection device 8 includes an inflatable air cushion 801, which is fixedly connected to the inner circumferential surface of the lower protection pipe 3. An air inlet pipe 802 is connected through and fixedly connected to the outer circumferential surface of the inflatable air cushion 801. A bend pipe 803 is fixedly connected to the end of the air inlet pipe 802 away from the inflatable air cushion 801. An air supply pipe 804 is fixedly connected to the top of the bend pipe 803. An air bladder 805 is fixedly connected to the end of the air supply pipe 804 away from the bend pipe 803. The bottom of the air bladder 805 is fixedly connected to the lower support plate 501. The purpose is to protect the heating pipe.

[0041] In some examples, the circumferential surface of the intake pipe 802 is connected to the circumferential surface of the lower protective pipe 3 through and fixedly connected to the circumferential surface of the air supply pipe 804 through and fixedly connected to the side of the lower support plate 501. The purpose of this is to achieve a through-structure and reduce material usage.

[0042] A protective plate 9 is fixedly connected to the top of the lower support plate 501, and a protective pad 10 is fixedly connected to the circumferential surface of the upper protective tube 1. The width of the protective pad 10 is slightly smaller than that of the upper protective tube 1, and its purpose is to play a safety protection role. The protective plate 9 limits the outward distance of its airbag 805.

[0043] There are two airbags 805 and two protective plates 9, which are symmetrical to each other along the central axis of the lower protective pipe 3. There are four air supply pipes 804 and four bends 803, which are arranged in pairs to increase working efficiency and make them more stable.

[0044] The top of the airbag 805 is located on the displacement trajectory of the bottom of the upper support plate 508, and the side of the protective plate 9 is located on the displacement trajectory of the side of the airbag 805. The purpose is to compress the airbag 805 to inflate the air cushion 801 and protect the airbag 805.

[0045] For example, such as Figures 1-5As shown, when the upper protective pipe 1 and the lower protective pipe 3 are connected, the bottom of the upper support plate 508 presses down on the airbag 805, forcing the gas inside the airbag 805 to be transported through the air supply pipe 804, through the bend pipe 803, to the air inlet pipe 802, and finally into the inflatable air cushion 801. After the inflatable air cushion 801 is injected with gas, it expands and tightly fits the outer wall of the heating pipe to form a buffer layer to absorb external impact. When the external pressure is released, the airbag 805 returns to its original shape due to its elasticity, and the gas inside the inflatable air cushion 801 flows back to the airbag 805 through the air inlet pipe 802, realizing system reset.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
