Description

Technical Field

[0001] This invention belongs to the field of pitched roof construction technology, and more specifically, relates to an aluminum-manganese plate pitched roof structure. Background Technology

[0002] With the continuous development of the modern construction industry and the constant innovation of building materials, various new materials have emerged, breaking the limitations of material use. Metal pitched roofs have also become a trend, and aluminum-manganese plate pitched roofs are now widely used in the construction industry.

[0003] Traditional pitched roof structures typically have gutters installed at the eaves to facilitate rainwater collection. Rainwater flows from the roof into the gutters and is then transported through pipes to a clear water tank, thus achieving a degree of water reuse. However, in practice, fallen leaves and other debris in the outdoor environment easily accumulate in the gutters with rainwater, causing blockages at the inlet of the pipes and rendering the gutters ineffective in collecting rainwater. To ensure that the gutters can collect rainwater properly, frequent manual cleaning of the debris is necessary, wasting manpower. Summary of the Invention

[0004] This invention provides an aluminum-manganese plate pitched roof structure that can avoid blockage at the inlet of the water pipe, ensure that the eaves gutter can collect rainwater normally, and save manpower.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an aluminum-manganese plate pitched roof structure is provided, including eaves gutters, a pitched roof, and a filter screen. The eaves gutters are located on the outside of the wall, and the bottom of the eaves gutters is connected to a downward-extending water pipe for guiding rainwater. The pitched roof is located above the wall, and the side of the pitched roof closest to the eaves gutters gradually slopes outward and downward. The filter screen covers the top of the eaves gutters and is used to filter impurities.

[0006] In one possible implementation, the aluminum-manganese panel pitched roof structure further includes a transition channel that penetrates the wall and extends downwards and inwards towards the wall, and an elastic sealing element that slides vertically within the transition channel and is used to seal the outer end of the transition channel. A filter screen is connected to the upper end of the elastic sealing element, and the side of the filter screen closest to the elastic sealing element gradually extends downwards. The outer edge of the filter screen slides vertically with the inner wall of the eaves gutter. The filter screen can drive the elastic sealing element to move downwards so that impurities can enter the transition channel.

[0007] In some embodiments, a receiving groove is provided on the inner bottom wall of the transition channel, and an elastic sealing member is slidably connected in the receiving groove. The elastic sealing member includes a sealing plate and an elastic member. The sealing plate is slidably connected in the receiving groove in the vertical direction. The elastic member is connected to the lower edge of the sealing plate and is used to elastically push the sealing plate upward to seal the transition channel.

[0008] In some embodiments, the sidewall of the sealing plate is provided with a rack extending in the vertical direction, and a conveying member located inside the elastic sealing member is provided in the transition channel. The conveying member is provided with a gear that meshes with the rack. The rack can move upward to drive the gear to rotate and cause the conveying member to transport impurities to the outlet end of the transition channel.

[0009] In some embodiments, a support is provided in the transition channel, and the conveying component includes two drive shafts and a conveyor belt. The two drive shafts are rotatably connected to the support and are spaced apart along the extension direction of the transition channel. A gear is fixedly sleeved on the drive shaft located near the sealing plate. The conveyor belt is wrapped around the outer periphery of the two drive shafts.

[0010] In some embodiments, a plurality of push teeth are provided on the outer peripheral wall of the drive shaft along the circumferential direction, the push teeth extend along the axial direction of the drive shaft, and the inner peripheral wall of the conveyor belt is provided with abutment teeth that mesh with the push teeth. The drive shaft is used to drive the conveyor belt to transport impurities to the outlet end of the transition channel.

[0011] In some embodiments, the aluminum-manganese plate pitched roof structure also includes a receiving box connected to the inner sidewall of the wall and located below the transition channel, with the receiving box opening upwards for containing impurities.

[0012] In some embodiments, a release channel is provided through the bottom wall of the receiving box, the release channel is located away from the inner wall of the wall, and a guide platform is provided at the inner bottom of the receiving box, the guide platform having a guide slope that gradually slopes downward from the side close to the wall to the side away from the wall.

[0013] In some embodiments, the aluminum-manganese plate pitched roof structure further includes a sliding cavity disposed on the inner side wall of the wall and communicating with the receiving box. The sliding cavity extends along the extension direction of the guide slope. An elastic pull member that slides and cooperates with the guide slope is slidably connected in the sliding cavity. A guide shaft is rotatably connected to the inner side wall of the release channel. A cleaning box located below the release channel is provided at the bottom of the receiving box. The cleaning box and the elastic pull member are connected by a pull rope wrapped around the guide shaft. The elastic pull member can elastically lift the cleaning box upward.

[0014] In some embodiments, the elastic pull-back member includes a tension spring and a pull plate. The tension spring is connected to the inner wall of the sliding cavity and extends toward the port of the sliding cavity. The pull plate is slidably connected inside the sliding cavity and connected to the extension end of the tension spring. The edge of the pull plate near the guide table is connected to the pull rope.

[0015] Compared with the prior art, the aluminum-manganese plate pitched roof structure provided in this embodiment allows rainwater to fall onto the pitched roof and flow into the eaves gutter along the slope of the roof, and then into the drainage pipe. Impurities fall onto the filter screen and remain on the top of the filter screen, preventing impurities from entering the eaves gutter and clogging the inlet of the drainage pipe. This ensures that the eaves gutter can collect rainwater normally and saves manpower. Attached Figure Description

The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the invention, "a number" means two or more, unless otherwise explicitly specified.

[0021] Please see Figures 1 to 3 The aluminum-manganese plate pitched roof structure provided by the present invention will now be described. The aluminum-manganese plate pitched roof structure includes a gutter 20, a pitched roof 30, and a filter screen 40. The gutter 20 is located on the outside of the wall 1, and a water pipe 21 extending downward and used to guide rainwater is connected to the bottom of the gutter 20. The pitched roof 30 is located above the wall 1, and the side of the pitched roof 30 near the gutter 20 gradually slopes outward and downward. The filter screen 40 covers the top of the gutter 20 and is used to filter impurities.

[0022] This application provides an aluminum-manganese plate pitched roof structure. In actual use, during rainy weather, rainwater falls onto the pitched roof 30 and flows along the slope of the pitched roof 30 into the eaves gutter 20 and into the water pipe 21. Impurities fall onto the filter screen 40 and remain on the top of the filter screen 40, preventing impurities from entering the eaves gutter 20 and clogging the inlet of the water pipe 21. This ensures that the eaves gutter 20 can collect rainwater normally and saves manpower.

[0023] Compared with the prior art, the aluminum-manganese plate pitched roof structure provided in this embodiment allows rainwater to fall onto the pitched roof 30 during rainy weather, flowing along the slope of the pitched roof 30 into the eaves gutter 20 and then into the water pipe 21. Impurities fall onto the filter screen 40 and remain on the top of the filter screen 40, preventing impurities from entering the eaves gutter 20 and clogging the inlet of the water pipe 21. This ensures that the eaves gutter 20 can collect rainwater normally and saves manpower.

[0024] In one possible implementation, the aforementioned wall 1 adopts the following... Figure 1 and Figure 2 The structure shown is described in the following document. Figure 1 and Figure 2The aluminum-manganese plate pitched roof 30 structure also includes a transition channel 10 that penetrates the wall 1 and extends downwards and inwards towards the inner side of the wall 1, and an elastic sealing member 50 that is slidably connected in the transition channel 10 in the vertical direction and is used to seal the outer end of the transition channel 10. A filter screen 40 is connected to the upper end of the elastic sealing member 50, and the side of the filter screen 40 close to the elastic sealing member 50 gradually extends downwards. The outer edge of the filter screen 40 is slidably connected to the inner wall of the eaves gutter 20 in the vertical direction. The filter screen 40 can drive the elastic sealing member 50 to move downwards so that impurities enter the transition channel 10.

[0025] Specifically, when impurities accumulate to a certain extent on the filter screen 40, they will press down on the filter screen 40. The filter screen 40 will cause the elastic sealing element 50 to move downward to avoid the port of the transition channel 10, thereby allowing the impurities to enter the transition channel 10 along the filter screen 40. After all the impurities on the filter screen 40 have entered the transition channel 10, the elastic sealing element 50 will move the filter screen 40 upward due to its own elastic force, blocking the inlet end of the transition channel 10. This resets the elastic sealing element 50 and the filter screen 40, ensuring timely and automatic cleaning of impurities on the filter screen 40 and preventing the accumulation of impurities on the filter screen 40.

[0026] The inner side of wall 1 is the side away from eaves gutter 20, the outer side of wall 1 is the side close to eaves gutter 20, the outer end of transition channel 10 is the end close to eaves gutter 20, and the outer edge of filter screen 40 is the side away from wall 1.

[0027] In some embodiments, see Figure 1 and Figure 2 The transition channel 10 has a receiving groove 12 on its inner bottom wall. The elastic sealing member 50 is slidably connected in the receiving groove 12. The elastic sealing member 50 includes a sealing plate 51 and an elastic member 52. The sealing plate 51 is slidably connected in the receiving groove 12 in the up and down direction. The elastic member 52 is connected to the lower edge of the sealing plate 51 and is used to elastically push the sealing plate 51 upward to seal the transition channel 10.

[0028] Specifically, when impurities accumulate to a certain extent on the filter screen 40, they will press down on the filter screen 40. The filter screen 40 will cause the sealing plate 51 to move downward to avoid the port of the transition channel 10 and compress the elastic element 52, so that the impurities will enter the transition channel 10 along the filter screen 40. After all the impurities on the filter screen 40 have entered the transition channel 10, the elastic element 52 will push the sealing plate 51 upward due to its own elastic force, and drive the filter screen 40 upward, thereby sealing the inlet end of the transition channel 10. This resets the sealing plate 51 and the filter screen 40, ensuring timely and automatic cleaning of impurities on the filter screen 40 and preventing the accumulation of impurities on the filter screen 40.

[0029] In some embodiments, see Figure 1 and Figure 2The side wall of the sealing plate 51 is provided with a rack 511 extending in the vertical direction. The transition channel 10 is provided with a conveying member 60 located inside the elastic sealing member 50. The conveying member 60 is provided with a gear 63 that meshes with the rack 511. The rack 511 can move upward to drive the gear 63 to rotate and cause the conveying member 60 to transport impurities to the outlet end of the transition channel 10.

[0030] Specifically, through the meshing of rack 511 and gear 63, the up-and-down movement of rack 511 can drive gear 63 to rotate, thereby driving conveyor 60 to convey impurities and avoiding the accumulation of impurities in transition channel 10.

[0031] After the impurities press down on the filter screen 40 and cause the sealing plate 51 to move down to a certain extent, the impurities will gradually roll off the filter screen 40 onto the conveying component 60. After all the impurities on the filter screen 40 have reached the conveying component 60, the elastic element 52 pushes the sealing plate 51 upward due to its own elastic force, and causes the filter screen 40 to move upward. As a result, the rack 511 drives the gear 63 to rotate, so that the conveying component 60 transports the impurities to the outlet end of the transition channel 10, thus avoiding the accumulation of impurities in the transition channel 10.

[0032] Optionally, the transition channel 10 is provided with a support 11, and the conveying component 60 includes two drive shafts 61 and a conveyor belt 62. The two drive shafts 61 are rotatably connected to the support 11 and are spaced apart along the extension direction of the transition channel 10. The gear 63 is fixedly sleeved on the drive shaft 61 located near the sealing plate 51. The conveyor belt 62 is wound around the outer periphery of the two drive shafts 61.

[0033] Optionally, a support 11 is provided in the transition channel 10, and the conveying component 60 includes a take-up shaft rotatably connected to the support 11. A gear 63 is fixedly sleeved on the outer periphery of the take-up shaft. A guide seat is slidably connected to the inner bottom wall of the transition channel 10 along the extension direction of the transition channel 10. The guide seat and the take-up shaft are connected by a take-up rope. The guide seat is used to receive impurities and guide them to the outlet end of the transition channel 10. The take-up shaft can wind and unwind the take-up rope to drive the guide seat to move.

[0034] In some embodiments, see Figure 1 and Figure 2 The transition channel 10 is provided with a support 11. The conveying component 60 includes two drive shafts 61 and a conveyor belt 62. The two drive shafts 61 are rotatably connected to the support 11 and are spaced apart along the extension direction of the transition channel 10. The gear 63 is fixedly sleeved on the drive shaft 61 near the sealing plate 51. The conveyor belt 62 is wrapped around the outer periphery of the two drive shafts 61.

[0035] Specifically, after the impurities press down on the filter screen 40 and cause the sealing plate 51 to move down to a certain extent, the impurities will gradually roll off the filter screen 40 onto the conveyor belt 62. After all the impurities on the filter screen 40 have reached the conveyor belt 62, the elastic element 52 pushes the sealing plate 51 upward due to its own elastic force, and causes the filter screen 40 to move upward. As a result, the rack 511 drives the gear 63 to rotate, causing the drive shaft 61 to rotate, driving the conveyor belt 62 to transport the impurities to the outlet end of the transition channel 10, thus avoiding the accumulation of impurities in the transition channel 10.

[0036] In some embodiments, see Figure 1 and Figure 2 The outer peripheral wall of the drive shaft 61 is provided with a plurality of push teeth 611 along the circumferential direction. The push teeth 611 extend along the axial direction of the drive shaft 61. The inner peripheral wall of the conveyor belt 62 is provided with abutment teeth 621 that mesh with the push teeth 611. The drive shaft 61 is used to drive the conveyor belt 62 to transport impurities to the outlet end of the transition channel 10.

[0037] Specifically, if the drive shaft 61 rotates in the forward direction, the push tooth 611 and the abutment tooth 621 can mesh, allowing the conveyor belt 62 to transport impurities to the outlet end of the transition channel 10. If the drive shaft 61 rotates in the reverse direction, the push tooth 611 cannot mesh with the abutment tooth 621, thus preventing the conveyor belt 62 from rotating. In other words, during the downward movement of the rack 511, the conveyor belt cannot transport impurities to the inlet end of the transition channel 10, avoiding the accumulation of impurities at the inlet end of the transition channel 10 and improving practicality.

[0038] In some embodiments, see Figure 1 and Figure 3 The aluminum-manganese plate pitched roof 30 structure also includes a receiving box 70 connected to the inner side wall of the wall 1 and located below the transition channel 10. The receiving box 70 has an upward opening and is used to receive impurities.

[0039] Specifically, the container 70 is used to collect impurities transported from the transition channel 10, preventing impurities from falling everywhere and facilitating unified cleaning by staff.

[0040] In some embodiments, see Figure 1 and Figure 3 A release channel 71 is provided through the bottom wall of the receiving box 70. The release channel 71 is located away from the inner wall of the wall 1. A guide platform 72 is provided at the inner bottom of the receiving box 70. The guide platform 72 has a guide slope 721 that gradually slopes downward from the side close to the wall 1 to the side away from the wall 1.

[0041] Specifically, the release channel 71 is used to allow impurities to pass through. The guide ramp 721 on the guide platform 72 allows impurities that fall on the guide ramp 721 to slide into the release channel 71, avoiding the accumulation of impurities on the inner bottom wall of the receiving box 70 and improving practicality.

[0042] In some embodiments, see Figure 1 and Figure 3 The aluminum-manganese plate pitched roof 30 structure also includes a sliding cavity 13 disposed on the inner side wall of the wall 1 and connected to the receiving box 70. The sliding cavity 13 extends along the extension direction of the guide slope 721. An elastic pull member 80 that slides and cooperates with the guide slope 721 is slidably connected in the sliding cavity 13. A guide shaft 73 is rotatably connected on the inner side wall of the release channel 71. A cleaning box 90 located below the release channel 71 is provided at the bottom of the receiving box 70. The cleaning box 90 and the elastic pull member 80 are connected by a pull rope 91 wrapped around the guide shaft 73. The elastic pull member 80 can elastically lift the cleaning box 90 upward.

[0043] Specifically, the impurities entering the receiving box 70 eventually fall into the impurity removal box 90. As the impurities in the impurity removal box 90 gradually increase, the impurity removal box 90 is gradually pulled downward by the elastic pull member 80 through the pull rope 91. During this process, the elastic pull member 80 scrapes the guide slope 721, causing the impurities attached to the guide slope 721 to enter the impurity removal box 90. This not only facilitates the timely cleaning of the impurity removal box 90 by the staff, but also cleans the guide slope 721, improving its practicality.

[0044] After the impurities in the impurity removal box 90 are cleaned, the elastic pull-back component 80 will automatically pull the impurity removal box 90 back to its initial position to continue receiving impurities, thus improving its practicality.

[0045] In some embodiments, see Figure 1 and Figure 3 The elastic pull-back member 80 includes a tension spring 81 and a pull plate 82. The tension spring 81 is connected to the inner wall of the sliding cavity 13 and extends toward the port of the sliding cavity 13. The pull plate 82 is slidably connected inside the sliding cavity 13 and connected to the extension end of the tension spring 81. The edge of the pull plate 82 near the guide table 72 is connected to the pull rope 91.

[0046] Specifically, the impurities entering the receiving box 70 eventually fall into the impurity removal box 90. As the impurities in the impurity removal box 90 gradually increase, the impurity removal box 90 is gradually pulled downward by the pull rope 91, which in turn gradually stretches the tension spring 81. During this process, the pull plate 82 scrapes against the guide slope 721, causing the impurities attached to the guide slope 721 to enter the impurity removal box 90. This not only facilitates the timely cleaning of the impurity removal box 90 by the staff, but also cleans the guide slope 721, improving its practicality.

[0047] After the impurities in the impurity removal box 90 are cleaned, the tension spring 81 pulls the pull plate 82 to retract and pulls the impurity removal box 90 back to its initial position to continue receiving impurities, thus improving its practicality.

[0048] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
