[0028] This utility model provides a venting pipe trash rack and a reservoir venting system, which will be described in detail below with reference to specific embodiments.

[0029] like Figure 1 As shown in the figure, an embodiment of the present invention provides a vent pipe debris barrier, including a mounting frame 1, an anchor 2, and a barrier blade assembly 3; the mounting frame 1 has a cavity for communicating with the vent pipe 4; the anchor 2 passes through the mounting frame 1, with one end extending outside the mounting frame 1 and the other end extending into the cavity; the barrier blade assembly 3 is disposed in the cavity and is detachably connected to the end of the anchor 2 located in the cavity.

[0030] Specifically, the mounting frame 1 can be connected to the vent pipe 4 and both are installed at the bottom of the reservoir, while the end of the anchor 2 extending outside the mounting frame 1 can be anchored in the concrete at the bottom of the reservoir.

[0031] In this embodiment, by placing the screen blade assembly 3 in the cavity and detachably connecting it to the end of the anchor 2 located within the cavity, the screen blade assembly 3 can be detachably installed. This allows for quick disassembly and replacement of the screen blade assembly 3 when maintenance of the trash rack is required, improving the convenience of maintenance and replacement. In addition, by placing the anchor 2 in the mounting frame 1, with one end of the anchor 2 extending outside the mounting frame 1, this end of the anchor 2 can be anchored inside the concrete at the bottom of the reservoir during construction, thereby improving the stability of the entire trash rack relative to the bottom of the reservoir. Furthermore, based on the fact that one end of the anchor 2 can be anchored to the bottom of the reservoir, by connecting the screen blade assembly 3 to the other end of the anchor 2 extending into the cavity, the screen blade assembly 3 can be indirectly connected to the concrete at the bottom of the reservoir, thereby improving the installation stability of the screen blade assembly 3.

[0032] Optionally, such as Figure 2As shown, the anchor 2 includes a connecting rod 21 and an anchor hook 22 connected to each other. The connecting rod 21 passes through the mounting frame 1, and the anchor hook 22 is located at the end of the connecting rod 21 that extends outside the mounting frame 1. The grating assembly 3 is connected to the end of the connecting rod 21 that extends into the cavity.

[0033] In this optional embodiment, by setting the anchor 2 as a connected connecting rod 21 and anchor hook 22, the anchor hook 22 can improve the anchoring effect of the anchor 2 at the bottom of the reservoir, further improve the connection stability between the trash rack and the bottom of the reservoir, and further improve the installation stability of the rack assembly 3.

[0034] Optionally, such as Figure 3 and Figure 4 As shown, the grating assembly 3 is provided with a connection hole 331; the anchor 2 passes through the connection hole 331, and a fastening nut 5 is screwed onto the end of the anchor 2 that protrudes from the connection hole 331.

[0035] Specifically, a spring washer 6 may also be fitted onto the anchor 2. The spring washer 6 is located between the fastening nut 5 and the gate blade assembly 3 to improve the stability of the screw connection.

[0036] In this optional embodiment, the detachable connection between the grid blade assembly 3 and the anchor 2 can be achieved by using the connection hole 331 and the fastening nut 5. The structure is simple and the disassembly and installation are relatively convenient. Furthermore, when the fastening nut 5 is tightened, the fastening nut 5 can press the grid blade assembly 3 onto the mounting frame 1, ensuring the integrity of the mounting frame 1, the anchor 2 and the grid blade assembly 3, thereby improving the structural stability of the entire trash rack.

[0037] Optionally, such as Figure 4 As shown, the connecting hole 331 is configured as an oblong hole, and the length direction of the oblong hole extends along the circumference of the grating assembly 3.

[0038] In this optional embodiment, by setting the connecting hole 331 as an oblong hole, and the oblong hole extending along the circumference of the blade assembly 3, the blade assembly 3 is allowed to be finely adjusted along its circumference during installation, thus avoiding installation problems of the blade assembly 3 caused by the misalignment of the anchor 2 during the concrete pouring process at the bottom of the reservoir.

[0039] Optionally, multiple anchors 2 are provided, and the multiple anchors 2 are arranged sequentially along the circumference of the mounting frame 1; the grating leaf assembly 3 is detachably connected to the multiple anchors 2 respectively.

[0040] In this optional embodiment, the presence of multiple anchors 2 can make the connection between the mounting frame 1 and the grid blade assembly 3 and the bottom of the reservoir more secure, thereby further improving the stability of the entire trash rack relative to the bottom of the reservoir, and further enhancing the installation stability of the grid blade assembly 3.

[0041] Optionally, such as Figure 3 As shown, the grating assembly 3 includes a frame 31, a grating structure 32, and a flange plate 33. The grating structure 32 is disposed inside the frame 31, and the flange plate 33 is connected to the outer periphery of the frame 31. The flange plate 33 is detachably connected to the anchor 2.

[0042] Specifically, the connecting hole 331 can be formed in the flange plate 33, the anchor 2 passes through the connecting hole 331 of the flange plate 33, and a fastening nut 5 is screwed onto the end of the anchor 2 that protrudes from the connecting hole 331, so as to realize the detachable connection between the flange plate 33 and the anchor 2. Figure 5 As shown, when multiple anchors 2 are provided, the flange plate 33 can be provided with multiple connecting holes 331 corresponding to the multiple anchors 2. The multiple anchors 2 are used to pass through the multiple connecting holes 331 one by one, and a fastening nut 5 is screwed to the end of each anchor 2, so that the flange plate 33 can be detachably connected to the multiple anchors 2. Specifically, a reinforcing plate 34 can be connected between the frame 31 and the flange plate 33 to improve the connection strength between the frame 31 and the flange plate 33.

[0043] In this optional embodiment, the grid blade assembly 3 is configured as a frame 31, a grid bar structure 32, and a flange plate 33. The grid bar structure 32 can be used to block dirt. By placing the grid bar structure 32 inside the frame 31, it is convenient to install the grid bar structure 32 and can also better protect the grid bar structure 32. In addition, by connecting the flange plate 33 to the outer periphery of the frame 31 and detachably connecting the flange plate 33 to the anchor 2, that is, the entire grid blade assembly 3 is detachably connected to the anchor 2 by means of the flange plate 33. It is also easier to open the connection hole 331 and install the fastening nut 5 on the flange plate 33, thereby making the processing and installation of the trash rack more convenient.

[0044] Optionally, such as Figure 3 As shown, a support beam 35 is also provided inside the frame 31. The support beam 35 is located on the side of the grid structure 32 near the vent pipe 4 and is connected to the frame 31; at least part of the grid structure 32 is supported on the support beam 35.

[0045] Specifically, the grid structure 32 may include grid bars 321 and stiffening plates 322 that are interconnected and intersecting. Multiple grid bars 321 may be arranged along the length of the stiffening plates 322, and multiple stiffening plates 322 may be arranged along the length of the grid bars 321. For at least a portion of the grid structure 32 to be supported on the support beam 35, one of the grid bars 321 or stiffening plates 322 of the grid structure 32 may be supported on the support beam 35.

[0046] In this optional embodiment, the support beam 35 can support the grid structure 32, thereby improving the structural stability of the grid structure 32 relative to the frame 31, making the grid structure 32 less prone to deformation and damage, and reducing the frequency of maintenance and replacement.

[0047] Optionally, such as Figure 2 As shown, the mounting frame 1 includes a cylindrical body 11 and a first annular plate 12. The internal space of the cylindrical body 11 forms the cavity. The first annular plate 12 is located at one end of the cylindrical body 11, and the outer periphery of the first annular plate 12 is connected to the inner periphery of the cylindrical body 11. The anchor 2 passes through the first annular plate 12.

[0048] Specifically, the first annular plate 12 may have a threaded hole, and the anchor 2 is screwed into the threaded hole.

[0049] In this optional embodiment, by placing the first annular plate 12 inside the cylinder 11, with the outer periphery of the first annular plate 12 correspondingly connected to the inner periphery of the cylinder 11, and inserting the anchor 2 through the first annular plate 12, that is, the entire mounting frame 1 is connected to the anchor 2 by means of the first annular plate 12. Thus, when the grating blade assembly 3 is detachably connected to the anchor 2, the grating blade assembly 3 can be supported on the first annular plate 12 at the same time, thereby ensuring the installation stability of the grating blade assembly 3. Furthermore, since the first annular plate 12 is located at one end of the cylinder 11, the mounting frame 1 can provide a cavity with a greater depth to accommodate the grating blade assembly 3.

[0050] Optionally, such as Figure 2 As shown, the mounting frame 1 also includes a second annular plate 13 and a reinforcing plate 14. The second annular plate 13 is located at the other end of the cylinder 11, and the inner circumference of the second annular plate 13 is connected to the outer circumference of the cylinder 11. The reinforcing plate 14 is connected to the second annular plate 13 and the cylinder 11 respectively.

[0051] In this optional embodiment, by connecting the inner circumference of the second annular plate 13 to the outer circumference of the cylinder 11, the surface area of ​​the mounting frame 1 in the vertical direction can be relatively increased. This increases the resistance to the sinking of the mounting frame 1 during the concrete pouring process at the bottom of the reservoir, preventing the mounting frame 1 from sinking and improving the construction quality of the mounting frame 1. Moreover, by connecting the reinforcing plate 14 between the second annular plate 13 and the cylinder 11, the structural strength of the mounting frame 1 can be improved, making the mounting frame 1 less prone to deformation.

[0052] This utility model provides a reservoir venting system, including a venting pipe 4 and a venting pipe debris barrier as described above. The venting pipe 4 is connected to the venting pipe debris barrier, and the venting pipe 4 and the venting pipe debris barrier are used to jointly pass through the bottom of the reservoir. The end of the anchor 2 of the venting pipe debris barrier extending out of the mounting frame 1 is anchored in the bottom concrete of the reservoir.

[0053] Specifically, the vent pipe 4 can be connected to the inner circumference of the first annular plate 12 of the mounting frame 1. It should be noted that the outer diameter of the vent pipe 4 may be smaller than the inner diameter of the first annular plate 12. In this case, a connecting section with an outer radially gradually increasing diameter can be provided at the upper end of the vent pipe 4. The outer diameter of the upper end of the connecting section is approximately equal to the inner diameter of the first annular plate 12, so that the upper end of the connecting section can be connected to the inner circumference of the first annular plate 12, thereby realizing the connection between the vent pipe 4 and the vent pipe trash rack.

[0054] In this embodiment, since the reservoir venting system includes the aforementioned venting pipe trash rack, it possesses all the beneficial effects of all embodiments of the aforementioned venting pipe trash rack, and at least the following beneficial effects: Specifically, by placing the rack blade assembly 3 in the cavity and detachably connecting it to the end of the anchor 2 located within the cavity, the rack blade assembly 3 can be detachably installed, thereby enabling quick disassembly and replacement of the rack blade assembly 3 when maintenance is required, improving the convenience of maintenance and replacement; in addition, by placing the anchor 2 in the mounting frame 1, with one end of the anchor 2 extending outside the mounting frame 1, this end of the anchor 2 can be anchored inside the concrete at the bottom of the reservoir during construction, thereby improving the stability of the entire trash rack relative to the bottom of the reservoir; furthermore, based on the fact that one end of the anchor 2 can be anchored to the bottom of the reservoir, by connecting the rack blade assembly 3 to the other end of the anchor 2 extending into the cavity, the rack blade assembly 3 can be indirectly connected to the concrete at the bottom of the reservoir, thereby improving the installation stability of the rack blade assembly 3.

[0055] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
