Description

Technical Field

[0001] This utility model relates to the field of heating technology, and in particular to a heating energy-saving device. Background Technology

[0002] Energy-saving heating equipment reduces energy consumption and waste by optimizing the processes of heat production, transmission, distribution, or utilization. It improves energy efficiency while meeting users' required heating temperature and heat demand, thereby achieving the goals of energy conservation, reduced operating costs, and reduced carbon emissions. It is commonly used in building heating and industrial heating applications.

[0003] For example, steam heating energy-saving equipment uses steam as the heat medium, and transports heat from the heat source to the end through main pipes and branch pipes. In existing technologies, although most main pipes and branch pipes are detachably connected by flanges and bolts, they lack positioning structures. When multiple branch pipes are involved in the installation, there is still a problem of low installation efficiency, which may lead to longer downtime and indirectly increase the energy consumption when the heat source is on standby. Utility Model Content

[0004] The main purpose of this utility model is to provide a heating energy-saving device that improves the installation efficiency of main pipes and branch pipes and reduces equipment downtime for maintenance through a quick positioning structure.

[0005] The technical solution of this utility model is as follows:

[0006] A heating energy-saving device includes a heating device body, a main pipe, and branch pipes. The heating device body is detachably connected to the main pipe, and the main pipe is detachably connected to the branch pipes. The device is characterized in that a first positioning structure is provided on the side of the main pipe facing the branch pipes, and a second positioning structure is provided on the side of the branch pipes facing the main pipes.

[0007] The first positioning structure is provided with a first fixing ring, and the first fixing ring is provided with a plurality of first positioning grooves on the side facing the branch pipe. The second positioning structure is provided with a second fixing ring, and the second fixing ring is provided with a plurality of second positioning blocks on the side facing the first positioning groove. The second positioning blocks are rotatably connected to the first positioning groove, and the second positioning blocks are provided with an auxiliary fixing structure on the side facing the first positioning groove.

[0008] In one possible implementation, each of the first positioning grooves is arranged circumferentially along the center of the first fixing ring, and the first positioning groove is provided with a positioning guide slope to facilitate the sliding of the second positioning block.

[0009] In one possible implementation, the auxiliary fixing structure includes a guide groove and a fixing post. The guide groove is located on the side of the first fixing ring facing the second positioning block, and the fixing post is located on the side of the second positioning block facing the first positioning groove. The guide groove has a fixing groove, and the fixing post has a positioning bead on the side facing the fixing groove. The positioning bead is embedded in the fixing groove.

[0010] In one possible implementation, the first retaining ring has an unlocking through hole on the side facing the retaining groove, and a sealing plug is provided in the unlocking through hole.

[0011] In one possible implementation, the first fixing ring and the second fixing ring are respectively located on the outside of the main pipe and the branch pipe.

[0012] In one possible implementation, the first fixing ring has a sealing groove on the side facing the second fixing ring, and the second fixing ring has an elastic sealing element on the side facing the sealing groove, the elastic sealing element being embedded in the sealing groove.

[0013] In one possible implementation, the sealing groove has an annular cross-section, and the elastic seal is detachably connected to the sealing groove.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] After aligning the second fixing ring of the branch pipe with the first fixing ring of the main pipe, rotate the second fixing ring to adjust it, allowing the end of the auxiliary fixing structure to slide into the guide groove along the guide ramp. Simultaneously, several second positioning blocks on the second fixing ring also slide into their corresponding first positioning grooves along the positioning guide ramp of the first positioning groove. At this point, the positioning and initial fixing of the main pipe and branch pipe are complete. Maintenance personnel only need to further tighten both using bolts or other fasteners.

[0016] During installation, the first and second positioning structures, in conjunction with the positioning guide ramps, quickly achieve the positioning and docking of the main pipe and branch pipes. The positioning beads and fixing grooves of the auxiliary fixing structure reinforce the connection, significantly improving installation efficiency. Furthermore, the elastic seal effectively reduces internal heat leakage and heat loss, improving the energy efficiency of the equipment. This structure can also be used for rapid positioning and installation between branch pipes, enhancing the applicability of this embodiment. Attached Figure Description

[0028] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0029] like Figures 1-7As shown, this embodiment proposes a heating energy-saving device, including a heating device body 1, a main pipe 2, and branch pipes 3. The heating device body 1 and the main pipe 2 are detachably connected. When the heating device body 1 malfunctions or requires regular maintenance, the main pipe 2 can be disassembled for repair or replacement, reducing maintenance time and costs. The detachable connection between the main pipe 2 and the branch pipes 3 can adapt to pipe layouts in different scenarios and facilitates individual repair and replacement of each pipe, improving the flexibility and economy of this embodiment.

[0030] The main pipe 2 has a first positioning structure 21 on the side facing the branch pipe 3, and the branch pipe 3 has a second positioning structure 31 on the side facing the main pipe 2. The first positioning structure 21 has a first fixing ring 22, and the first fixing ring 22 has several first positioning grooves 23 on the side facing the branch pipe 3. The second positioning structure 31 has a second fixing ring 32, and the second fixing ring 32 has several second positioning blocks 33 on the side facing the first positioning grooves 23. The design of several first positioning grooves 23 and second positioning blocks 33 can form multi-point docking with multiple positioning blocks of the branch pipe 3, reducing deformation or loosening of each pipe due to uneven force at a single point.

[0031] The second positioning block 33 is rotatably connected to the first positioning groove 23, and the first positioning groove 23 is provided with a positioning guide slope 231 to facilitate the sliding of the second positioning block 33. This inclined transition structure reduces jamming during docking. Furthermore, precise alignment of the second positioning block 33 and the entrance of the first positioning groove 23 is not required during assembly; the positioning guide slope 231 guides the second positioning block 33 into the groove, significantly reducing the difficulty of alignment for maintenance personnel and shortening assembly time. Simultaneously, the positioning guide slope 231 reduces wear on the edges of both components, improving the smoothness of the sliding process.

[0032] After aligning the second fixing ring 32 with the first fixing ring 22, rotate the second fixing ring 32. At this time, the second positioning block 33 will slide into the first positioning groove 23 as it rotates and is guided by the positioning guide slope 231, thus completing the positioning. At this time, maintenance personnel can further fix the two with fasteners. At the same time, each first positioning groove 23 is circumferentially arranged along the center of the first fixing ring 22, so that when the second positioning block 33 is connected to the first positioning groove 23, the force point can be evenly distributed along the circumference of the pipe, avoiding deformation of the fixing ring or pipe connection misalignment caused by local force concentration, and ensuring the coaxiality of the main pipe 2 and the branch pipe 3.

[0033] In this embodiment, all detachable connections and fasteners are made of bolts. The advantage of bolted connections is that they offer high connection strength and stability, effectively reducing problems such as component displacement and functional failure caused by loose connections, thus improving the overall reliability of the structure. Furthermore, bolted connections are simple to operate, facilitating equipment installation, maintenance, and component replacement, thereby enhancing the convenience and speed of installation and maintenance in this embodiment.

[0034] In this embodiment, both the first fixing ring 22 and the second fixing ring 32 are respectively located on the outside of the main pipe 2 and the branch pipe 3, avoiding direct contact with the heat inside the pipe and improving the service life of this embodiment. Furthermore, during assembly, there is no need to delve into the pipe for alignment; maintenance personnel can directly operate the second fixing ring 32 from the outside of the pipe for positioning and installation. Moreover, the outer space of the pipe is more ample, improving the adaptability of this embodiment. The dimensions of this embodiment can be customized according to actual conditions, which will not be elaborated upon further in this embodiment.

[0035] In this embodiment, the second positioning block 33 is provided with an auxiliary fixing structure 4 on the side facing the first positioning groove 23, which effectively reduces the shaking of the pipeline when maintenance personnel fix the first fixing ring 22 and the second fixing ring 32 with fasteners, thus improving the installation efficiency. The auxiliary fixing structure 4 includes a guide groove 41 and a fixing post 42. The guide groove 41 is located on the side of the first fixing ring 22 facing the second positioning block 33, and the fixing post 42 is located on the side of the second positioning block 33 facing the first positioning groove 23. The entrance of the guide groove 41 is provided with a rounded corner to facilitate the entry of the fixing post 42. The guide groove 41 is provided with a fixing groove 43, and the fixing post 42 is provided with a positioning bead 44 on the side facing the fixing groove 43, which is embedded in the fixing groove 43.

[0036] When the fixed post 42 rotates with the second positioning block 33 to the first positioning groove 23, the end of the fixed post 42 slides into the first positioning groove 23 along the positioning guide slope 231. Then, with further rotation, its end slides to the rounded corner of the guide groove 41 and slides into the guide groove 41. At this time, the bead head of the positioning bead 44 is squeezed by the inner wall of the guide groove 41 and retracts into the fixed post 42. When the fixed post 42 slides into the fixed groove 43, the bead head of the positioning bead 44 resets. Figure 7 As shown, its bead head is embedded in the fixing groove 43. Maintenance personnel only need to rotate and slide to achieve auxiliary fixing between the pipes. Moreover, the elastic deformation characteristics of the positioning bead 44 can not only initially fix the pipes, but also do not affect the later unlocking by external force, thus improving the convenience of installation and disassembly.

[0037] In this embodiment, the fixing column 42 is machined using a CNC lathe. During machining, mounting holes for the positioning beads 44 are pre-drilled. After the fixing column 42 is machined, the positioning beads 44 are then press-fitted into the pre-drilled mounting holes. Meanwhile, the positioning beads 44 employ a compact structural design to ensure stable assembly even within a limited space.

[0038] In this embodiment, the first fixing ring 22 has an unlocking through hole 45 on the side facing the fixing groove 43. When the positioning bead 44 is too tightly stuck in the fixing groove 43, or when its spring is rusted and becomes stuck, there is no need to damage the positioning bead 44 or the fixing groove 43. Simply insert a tool through the unlocking through hole 45 to directly act on the positioning bead 44 in the fixing groove 43, press and pull the second fixing ring 32 outward to disengage it from the fixing groove 43. This design reduces the difficulty of maintenance and operation, while protecting the integrity of the auxiliary fixing structure 4.

[0039] Meanwhile, a sealing plug 46 is provided inside the unlocking through hole 45. When the equipment is running normally, it can effectively prevent external dust, moisture and impurities from entering the fixing groove 43 or guide groove 41 through the unlocking through hole 45, reduce the possibility of the positioning bead 44 getting stuck and the parts corroding, and extend the service life of the auxiliary fixing structure 4.

[0040] In this embodiment, the first fixing ring 22 has a sealing groove 5 on the side facing the second fixing ring 32, and the second fixing ring 32 has an elastic sealing element 51 on the side facing the sealing groove 5. The elastic sealing element 51 is embedded in the sealing groove 5, and the sealing groove 5 forms a wrapping constraint on the elastic sealing element 51, improving the connection stability between it and the second fixing ring 32. At the same time, the elastic sealing element 51, relying on its own elastic deformation characteristics, can tightly fill the tiny gap between the mating surfaces of the first fixing ring 22 and the second fixing ring 32. After being fixed by fasteners, the second fixing ring 32 compresses the elastic sealing element 51, causing it to deform, thereby achieving a tight fit, reducing the possibility of internal heat leakage between the first fixing ring 22 and the second fixing ring 32, and ensuring the sealing performance of this embodiment during long-term operation.

[0041] In this embodiment, the sealing groove 5 has an annular cross-section, which is adapted to the structure of the first fixing ring 22 and the second fixing ring 32. It can cover the entire circumferential gap of each pipe mating surface, reducing the risk of local hot gas leakage due to incomplete sealing area. The elastic seal 51 is detachably connected to the sealing groove 5. When the sealing performance of the elastic seal 51 deteriorates due to aging or wear, it is not necessary to disassemble or replace the entire first fixing ring 22. The old elastic seal 51 can be directly removed from the sealing groove 5 and replaced with a new one to complete the maintenance, reducing the difficulty of operation and maintenance costs.
