[0002] As people's quality of life improves, their material life becomes richer, and they pursue a high-quality life, people's demand for residential and office buildings is increasing, and the demand for heating is also increasing. At present, heating facilities are usually installed in a concealed manner, that is, in the early stage of building wall decoration, wire pipe grooves need to be dug on the wall surface to bury water heating pipes, and then covered with cement after the lines are laid. This method increases the difficulty of later inspection and maintenance of heating facilities, so further improvement is needed. Summary of the invention

[0003] In order to reduce the difficulty of inspecting and maintaining heating facilities, the present application provides a water heating pipe structure for the wall of an assembled building.

[0004] The present application provides a water heating pipe structure for a prefabricated building wall using the following technical solution: A water heating pipe structure for the wall of an assembled building comprises a first wall, a second wall detachably connected to the first wall, a pipe body arranged between the first wall and the second wall, and a radiator arranged between the first wall and the second wall, wherein the first wall and the second wall are provided with reserved pipe grooves and installation rooms on the opposite wall surfaces, the radiator is installed in the installation room, the pipe body is installed in the reserved pipe groove, the pipe body comprises an inlet pipe and an outlet pipe, the inlet pipe is connected to the water inlet of the radiator, the outlet pipe is connected to the water outlet of the radiator, and a heating outlet groove connected to the installation room is provided on the wall surface of the second wall away from the first wall.

[0005] By adopting the above technical solution, the second wall and the first wall are detachably connected. When the pipeline body or the radiator needs to be inspected and maintained, it is only necessary to remove the second wall from the first wall to expose the water inlet pipe, the water outlet pipe and the radiator. The water inlet pipe, the water outlet pipe and the radiator can then be inspected and maintained, avoiding destructive grooving operations on the wall and reducing the difficulty of inspecting and maintaining the pipeline body and the radiator.

[0006] Preferably, a protective cover embedded in the installation room is provided between the first wall and the second wall, and the protective cover includes a first cover shell installed in the first wall installation room and a second cover shell detachably connected to the first cover shell and embedded in the second wall installation room, and the first cover shell / second cover shell relative side walls are provided with avoidance openings for the passage of water inlet pipes / outlet pipes, the radiator is built into the protective cover, and the side wall of the second cover shell away from the first cover shell has an air outlet, the air outlet is connected to the heating outlet slot and the inner cavity of the protective cover, and the second cover shell is rotatably connected to a dust baffle for controlling the opening and closing of the air outlet, and the second cover shell is provided with a control component for driving the dust baffle to rotate.

[0007] By adopting the above technical solution, under normal conditions, multiple dust baffles are in a vertical state, thereby closing the air outlet, effectively reducing the possibility of indoor dust entering the protective cover from the air outlet and being adsorbed on the radiator, thereby ensuring the heat dissipation effect of the radiator. When the radiator is heating, the dust baffle is driven to rotate through the control component to open the air outlet, and the hot air blown out of the radiator is blown out from the air outlet through the heating outlet slot into the room. When the radiator needs to be inspected and maintained, the second wall is removed from the first wall, and the second cover is removed to expose the radiator, and the radiator can be inspected and maintained.

[0008] Preferably, the first cover shell and the second cover shell are both heat insulation covers.

[0009] By adopting the above technical solution, the possibility of the radiator directly contacting the first wall and the second wall is reduced, thereby reducing the possibility of the second wall and the first wall being damaged or thermal expansion and contraction.

[0010] Preferably, the air outlet is provided in plurality, and the plurality of air outlets are vertically spaced and distributed, and the dust baffle is provided in plurality correspondingly.

[0011] By adopting the above technical solution, the width of the dustproof baffle is reduced, thereby increasing the rotation angle of the dustproof baffle.

[0012] Preferably, the outer wall of each dust baffle is protruding and fixedly connected to a rotating shaft, which is rotatably connected to the inner wall of the air outlet, and the control component includes a transmission gear coaxially fixedly sleeved on the rotating shaft, a transmission rack vertically slidably connected to the second cover shell and meshing with multiple transmission gears, and a driving component that drives the transmission rack to slide.

[0013] By adopting the above technical solution, the relative rotation of the dust baffle and the second cover shell is achieved through the rotating shaft, and the transmission rack is driven to slide through the driving component, thereby synchronously driving multiple transmission gears to rotate, and then synchronously achieving the rotation of multiple dust baffles to achieve the closing or opening of the air outlet.

[0014] Preferably, the driving component is a driving cylinder, the cylinder body of the driving cylinder is fixedly connected to the second cover shell, the piston rod of the driving cylinder is axially arranged vertically, and the end of the piston rod of the driving cylinder is fixedly connected to the transmission rack.

[0015] By adopting the above technical solution, the piston rod of the driving cylinder is extended and retracted to drive the transmission rack to slide, thereby realizing the closing or opening of the air outlet.

[0016] Preferably, the water inlet pipe is externally connected to a delivery pump, and a control pipe is connected between the pipe mouth of the water inlet pipe and the water inlet of the radiator, one end of the control pipe is open, and the other end of the control pipe is closed, the open end of the control pipe is connected to the water inlet pipe, and a water inlet hole connected to the water inlet of the radiator is opened in the middle of the outer wall of the control pipe, and the driving component includes a sealing plate that is coaxially sealed and slidably connected to the inner circumferential wall of the control pipe, a first spring fixedly connected between the inner wall of the closed end of the control pipe and the sealing plate, a linkage rope with one end fixedly connected to the side of the sealing plate away from the water inlet pipe, a mounting pipe fixedly connected to the inner wall of the second cover shell, a movable rod fixedly connected to the end of the transmission rack and slidably inserted in the mounting pipe, and a second spring arranged between the mounting pipe and the movable rod, the other end of the linkage rope is passed through the closed end of the control pipe and fixedly connected to the movable rod, the first spring forces the sealing plate to normally slide down between the water inlet hole and the open end of the control pipe to close the water inlet hole, and the second spring can force the movable rod to slide and reset, and the elastic force of the first spring is greater than the elastic force of the second spring.

[0017] By adopting the above technical solution, under normal conditions, the first spring forces the sealing plate to slide between the water inlet hole and the open end of the control tube to close the water inlet hole. The sliding of the sealing plate pulls the movable rod to move through the linkage rope, thereby driving the transmission rack to slide, so that the dust baffle rotates forward to a vertical state to close the air outlet. At this time, the second spring undergoes elastic deformation and has elastic potential energy. When the delivery pump is working to deliver hot water to the water inlet pipe, when the water pressure in the water inlet pipe is greater than the elastic force of the first spring, the water in the water inlet pipe pushes the sealing plate toward the closed end close to the control tube. The first spring elastically deforms and has elastic potential energy, and causes the sealing plate to slide between the water inlet and the closed end of the control tube. Hot water enters the radiator from the water inlet and the water inlet of the radiator in turn for heat exchange. At the same time, the second spring elastically resets and forces the movable rod to slide and reset, thereby driving the transmission rack to slide, causing the dust baffle to rotate in the opposite direction and open the air outlet to allow hot air on the radiator to be discharged. The delivery pump stops working, and the first spring elastically resets and forces the sealing plate to slide and reset, and the dust baffle closes the air outlet again.

[0018] Preferably, a partition bar is provided on the side of the second cover shell away from the first cover shell, and a plurality of partition bars are provided and are vertically spaced apart, and an air outlet is formed between two adjacent partition bars. The dust baffle includes a main board rotatably connected to the inner wall of the air outlet and an extension plate slidably connected to the main board. A accommodating cavity is provided at the lower part of the main board, and the extension plate is slidably connected to the accommodating cavity. The partition bar is provided with a linkage part for adjusting the sliding position of the extension plate.

[0019] By adopting the above technical solution, when the main board is in a vertical state, the linkage part drives the extension plate to slide and retract into the accommodating cavity of the main board, thereby closing the air outlet. When the radiator is performing heating operation, the control component drives the free end of the main board to rotate outward, so that the air outlet is opened. At the same time, during the rotation of the main board, the linkage part drives the extension plate to extend out of the free end of the main board, thereby increasing the width of the dust baffle and extending the distance from the free end of the dust baffle to the wall surface of the second wall. The hot air from the radiator passes through the air outlet along the main board and the lower plate surface of the extension plate and then enters the room and rises, reducing the possibility of the wall surface of the second wall located above the heating outlet notch being blackened due to the direct rise of hot air, and reducing the possibility of damage to the wall.

[0020] Preferably, a slide groove connected to the accommodating cavity is provided on the back side of the main board, and the extension direction of the slide groove is parallel to the width direction of the main board. The extension plate protrudes and fixes a slider that is slidably connected to the slide groove. The linkage part is a linkage rod, one end of the linkage rod is hinged to the slider, and the other end of the linkage rod is hinged to the partition bar.

[0021] By adopting the above technical solution, when the radiator is performing heating operation, the control component drives the free end of the main board to rotate in the forward direction, so that the free end of the main board is exposed on the wall surface of the second wall. During the rotation of the main board, the extension plate is driven by the linkage rod to slide out of the free end of the main board, thereby increasing the width of the dust baffle and extending the distance from the free end of the dust baffle to the wall surface of the second wall. After the heating is over, the control component drives the main board to rotate in the opposite direction to reset, and the linkage rod forces the extension plate to slide inward into the accommodating cavity to achieve reset, so that the main board can close the air outlet.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. The second wall is detachably connected to the first wall. When the pipeline body or radiator needs to be repaired and maintained, the second wall only needs to be removed from the first wall to expose the water inlet pipe, water outlet pipe and radiator. The water inlet pipe, water outlet pipe and radiator can then be repaired, avoiding destructive grooving operations on the wall and reducing the difficulty of repairing and maintaining the pipeline body and radiator. 2. Under normal conditions, multiple dust baffles are in a vertical state, thereby closing the air outlet, effectively reducing the possibility of indoor dust entering the protective cover from the air outlet and being adsorbed on the radiator, thereby ensuring the heat dissipation effect of the radiator. When the radiator is heating, the dust baffle is driven to rotate through the control component to open the air outlet, and the hot air blown out of the radiator is blown out from the air outlet through the heating outlet slot into the room. When the radiator needs to be inspected and maintained, the second wall is removed from the first wall, and the second cover is removed, the radiator is exposed, and the radiator can be inspected and maintained; 3. The protective cover is a heat-insulating cover, which reduces the possibility of the radiator directly contacting the first wall and the second wall, thereby reducing the possibility of damage to the second wall and the first wall or thermal expansion and contraction.

[0036] Reference Figure 2 , Figure 3 , Figure 4 A protective cover 5 is provided between the first wall 1 and the second wall 2, which is embedded in the installation room 13 and used to cover the radiator 4. The protective cover 5 is a heat insulation cover. In this embodiment, the heat insulation cover is made of carbon fiber material. The protective cover 5 includes a first cover shell 51 and a second cover shell 52. The first cover shell 51 is fixedly connected to the installation room 13 of the first wall 1 by bolts. A bracket 53 is fixedly connected to the bottom inner wall of the first cover shell 51, and the radiator 4 is installed on the bracket 53. The second cover shell 52 is fixedly connected to the first cover shell 51 by bolts, and the second cover shell 52 is embedded in the installation room 13 of the second wall 2. The first cover shell 51 and the second cover shell 52 are provided with a avoidance opening 54 for the pipeline body 3 to pass through on the opposite side walls.

[0037] Reference Figure 4 , Figure 5 , Figure 6 The side wall of the second housing 52 has a mounting port connected to the heating outlet slot 23. The second housing 52 is fixedly connected to the left and right side walls of the mounting port with mounting plates 55. The mounting plates 55 are arranged vertically. A mounting cavity 56 is formed between the opposite sides of the two mounting plates 55 and the inner side wall of the second housing 52. A partition bar 57 is fixedly connected between the two mounting plates 55. The partition bars 57 are provided in multiple numbers and are arranged in a vertical interval. An air outlet is formed between two adjacent partition bars 57. The mounting plate 55 is rotatably connected to a dust baffle 6 for controlling the opening and closing of the air outlet. The dust baffle 6 includes a main board 61 rotatably connected to the mounting plate 55 and an extension plate 62 slidably connected to the main board 61. The outer side wall of the main board 61 protrudes and is fixed with a rotating shaft 63 rotatably connected to the mounting plate 55. The free end of the main board 61 is provided with a receiving cavity 64. The extension plate 62 is slidably connected to the receiving cavity 64. The end surface of the extension plate 62 is fixedly connected to a rubber strip 65.

[0038] A slide groove 66 connected to the accommodating cavity 64 is provided on the back of the main board 61. The extension direction of the slide groove 66 is parallel to the width direction of the main board 61. A slider 67 slidably connected to the slide groove 66 is protruded and fixed on the extension plate 62. A fixed plate 58 is fixedly connected to the inner wall of the partition bar 57. The fixed plate 58 is provided with a linkage member for adjusting the sliding position of the extension plate 62. The linkage member is a linkage rod 68. One end of the linkage rod 68 is hinged to the slider 67, and the other end of the linkage rod 68 is hinged to the fixed plate 58.

[0039] The end of the rotating shaft 63 extends into the installation cavity 56. The second housing 52 is provided with a control assembly 7 for driving the rotating shaft 63 to rotate. The control assembly 7 includes a transmission gear 71, a transmission rack 72, and a driving component 73. The transmission gear 71 is built into the installation cavity 56. The transmission gear 71 is coaxially fixedly sleeved on the rotating shaft 63. The transmission rack 72 is connected to the installation cavity 56 along a vertical sliding direction. The transmission rack 72 is meshed with a plurality of transmission gears 71. The driving component 73 is used to drive the transmission rack 72 to slide vertically. In this embodiment, the driving component 73 is a driving cylinder located below the transmission rack 72. The cylinder body of the driving cylinder is fixedly connected to the bottom inner wall of the second housing 52. The piston rod of the driving cylinder is axially arranged vertically. The end of the piston rod of the driving cylinder is fixedly connected to the lower end surface of the transmission rack 72.

[0040] The implementation principle of the embodiment of the present application is as follows: in the non-heating state, the piston rod of the driving cylinder is in an extended state, the multiple main boards 61 are in a vertical state, the extension plate 62 is retracted into the accommodating cavity 64, and the rubber strip 65 at the end of the extension plate 62 abuts against the upper surface of the partition bar 57, thereby closing the air outlet, effectively reducing the possibility of indoor dust entering the protective cover 5 from the air outlet and being adsorbed on the radiator 4; when the radiator 4 is heating, the piston rod of the driving cylinder is contracted, thereby driving the transmission rack 72 to move downward, and then driving the shaft 63 to rotate forward through the transmission gear 71, thereby driving the main board The free end of 61 is rotated 45° toward the outside of the second wall 2, so that the free end of the main board 61 is tilted downward. During the rotation of the main board 61, the extension plate 62 is driven by the linkage rod 68 to slide out of the free end of the main board 61, thereby increasing the width of the dust baffle 6 and extending the distance from the free end of the dust baffle 6 to the wall surface of the second wall 2. After the heating is over, the piston rod of the driving cylinder is extended and reset, driving the main board 61 to rotate in the opposite direction and reset. The linkage rod 68 forces the extension plate 62 to slide and retract into the accommodating cavity 64 to achieve reset, making it easier for the main board 61 to close the air outlet.

[0041] When it is necessary to inspect and maintain the pipe body 3 or the radiator 4, it is only necessary to remove the second wall 2 from the first wall 1 and the second cover 52 from the first cover 51, so that the pipe body 3 and the radiator 4 are exposed, and the pipe body 3 and the radiator 4 can be inspected and maintained, avoiding destructive grooving operations on the wall and reducing the difficulty of inspecting and maintaining the pipe body 3 and the radiator 4.

[0042] Embodiment 2: The difference from Example 1 is that, referring to Figure 7 , Figure 8The water inlet pipe 31 is connected to an external delivery pump, and a control pipe 33 is connected between the pipe mouth of the water inlet pipe 31 and the water inlet of the radiator 4. One end of the control pipe 33 is open, and the other end of the control pipe 33 is closed. The open end of the control pipe 33 is connected to the water inlet pipe 31, and a water inlet hole 34 connected to the water inlet of the radiator 4 is opened in the middle of the outer wall of the control pipe 33.

[0043] The driving component 73 includes a sealing plate 731 which is coaxially sealed and slidably connected to the inner wall of the control tube 33, a first spring 732 which is fixedly connected between the inner wall of the closed end of the control tube 33 and the sealing plate 731, a linkage rope 733 whose one end is fixedly connected to the side of the sealing plate 731 away from the water inlet pipe 31, a mounting tube 734 which is fixedly connected to the inner wall of the bottom of the second cover shell 52 and is located above the transmission rack 72, a movable rod 735 which is fixedly connected to the upper end of the transmission rack 72 and slidably inserted in the mounting tube 734, and a second spring 736 which is arranged between the mounting tube 734 and the movable rod 735. The other end of the linkage rope 733 is passed through the closed end of the control tube 33 and fixedly connected to the upper end of the movable rod 735. The first spring 732 forces the sealing plate 731 to slide between the water inlet hole 34 and the open end of the control tube 33 to close the water inlet hole 34. The second spring 736 can force the movable rod 735 to move up and reset. The elastic force of the first spring 732 is greater than the elastic force of the second spring 736. In this embodiment, the linkage rope 733 is formed by tying and fixing two ropes, one end of which is passed through the closed end face of the control tube 33 and fixedly connected to the sealing plate 731, and the other end of which is passed through the mounting tube 734 and fixedly connected to the upper end of the movable rod 735.

[0044] The implementation principle of Example 2 is as follows: in the non-heating state, the first spring 732 forces the sealing plate 731 to slide between the water inlet hole 34 and the open end of the control tube 33 to close the water inlet hole 34. During the sliding process of the sealing plate 731, the movable rod 735 is pulled upward by the linkage rope 733, thereby driving the transmission rack 72 to slide, so that the main board 61 rotates in the opposite direction to the vertical state to close the air outlet. At this time, the second spring 736 undergoes elastic deformation and has elastic potential energy; when heating operation is required, the delivery pump is started to deliver hot water to the water inlet pipe 31. When the water pressure in the water inlet pipe 31 is greater than the elastic force of the first spring 732, the water in the water inlet pipe 31 pushes the sealing plate 731. Sliding toward the closed end of the control tube 33, the first spring 732 undergoes elastic deformation and has elastic potential energy, and causes the sealing plate 731 to slide between the water inlet hole 34 and the closed end of the control tube 33, and hot water enters the radiator 4 from the water inlet hole 34 and the water inlet of the radiator 4 in turn to perform heat exchange operations. At the same time, the second spring 736 elastically resets to force the movable rod 735 to move downward, thereby driving the transmission rack 72 to move downward, causing the main board 61 to rotate forward so that the air outlet is in an open state, so that the hot air from the radiator 4 can be discharged into the room. When the delivery pump stops working, the first spring 732 elastically resets to force the sealing plate 731 to slide and reset, and the main board 61 closes the air outlet again.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
