[0036] Referring to Figs. 1 to 5 As shown in the drawings, a water pipeline drainage device includes a main pipeline 1 and a branch pipeline 2 communicating with the main pipeline 1, wherein the branch pipeline 2 is provided with a drainage assembly 3, and the drainage assembly 3 is arranged at one end of the branch pipeline 2 close to the main pipeline 1.
[0037] The drainage assembly 3 includes a filter plate 31 arranged in the branch pipeline 2, the filter plate 31 is conical, and the tip of the filter plate 31 faces the main pipeline 1, the branch pipeline 2 is provided with a sewage outlet 21, and the branch pipeline 2 is also provided with a sewage receiving box 22, the sewage receiving box 22 seals the sewage outlet 21, and the filtrate of the filter plate 31 enters the sewage receiving box 22 through the sewage outlet 21 under the impact of water flow.
[0038] The sewage receiving box 22 is provided with a sewage valve 221, and the sewage receiving box 22 is also provided with a partition plate 222, the partition plate 222 divides the sewage receiving box 22 into an upper cavity communicating with the sewage outlet 21 and a lower cavity communicating with the sewage valve 221, and the upper cavity and the lower cavity communicate through a port.
[0039] The main pipeline 1 and the branch pipeline 2 can be connected by welding.
[0040] The sewage valve 221 is a common valve body structure.
[0041] In some embodiments, the partition plate 222 can be welded in the sewage receiving box 22, and the partition plate 222 can also be fixed in the sewage receiving box 22 by other means.
[0042] In some embodiments, the partition plate 222 has a certain gap with the side wall of the sewage receiving box 22, and the gap forms the port.
[0043] In practice, the width of the mouth should be as narrow as possible, as long as the dirt filtered out by the filter plate 31 can pass through, the narrower the mouth, the more difficult it is for the dirt in the lower cavity to enter the upper cavity or the branch pipe 2, thereby preventing the branch pipe 2 from being blocked.
[0044] Referring to Figs. 1 to 5 As shown in some embodiments, the partition plate 222 is inclined, and the dirt in the upper cavity enters the lower cavity under the action of gravity, and the width of the dirt outlet 21 is smaller than the width of the upper cavity.
[0045] The width of the dirt outlet 21 is as narrow as possible, as long as the dirt filtered out by the filter plate 31 can pass through, the narrower the width of the dirt outlet 21, the more difficult it is for the liquid in the branch pipe 2 to enter the dirt box 22.
[0046] In some embodiments, the branch pipe 2 is also provided with a flow guide ring 23 that makes the liquid in the branch pipe 2 jump over the dirt outlet 21 under the action of inertia.
[0047] The flow guide ring 23 is fixed to the inner wall of the branch pipe 2, and the flow guide ring 23 is located between the main pipe 1 and the filter plate 31.
[0048] The end of the flow guide ring 23 close to the main pipe 1 is provided with an arc-shaped guide surface, and the arc-shaped guide surface smoothly transitions with the inner wall of the branch pipe 2.
[0049] The flow guide ring 23 is welded to the branch pipe 2, or the flow guide ring 23 is fixed to the branch pipe 2 by threads.
[0050] The flow guide ring 23 is used to guide the flow of water in the branch pipe 2. Specifically, the liquid in the branch pipe 2 has a certain flow rate, and generally, the greater the flow rate of the liquid, the greater the inertial force of the liquid. When the dirt outlet 21 is as narrow as possible, the liquid guided by the flow guide ring 23 can not contact the inner wall of the branch pipe 2 within a certain distance under the action of inertial force, and the dirt outlet 21 can be arranged within the range where the liquid does not contact the inner wall of the branch pipe 2, so as to avoid or reduce the liquid in the branch pipe 2 from entering the dirt box.
[0051] Referring to Figs. 1 to 5 As shown in some embodiments, although the flow in the branch pipe 2 may generate turbulence after contacting the filter plate 31, under the action of the turbulence, the liquid in the branch pipe 2 still enters the dirt box 22, but as long as the liquid in the branch pipe 2 does not directly enter the dirt box 22 in an impinging manner, the dirt in the dirt box 22 is not impacted by the liquid in the branch pipe 2, thereby preventing the dirt in the dirt box 22 from re-entering the branch pipe 2.
[0052] Since the liquid in the branch pipe 2 is turbulent after contacting the filter, the liquid in the branch pipe 2 is impacted by the turbulence, and the impact force of the liquid in the branch pipe 2 is reduced, so that even if the liquid enters the pollution box 22, the pollution in the pollution box 22 is not easy to enter the branch pipe 2 again.
[0053] In some embodiments, the filter plate 31 is mounted on the branch pipe 2 by a mounting frame, the mounting frame comprising a frame body 32 fixed to the branch pipe 2 and a connecting rod 33 fixing the filter plate 31 to the frame body 32.
[0054] The inner tangent axis of the connecting rod 33 is coaxially arranged with the filter plate 31, and the cross-sectional shape of the connecting rod 33 is polygonal.
[0055] In some embodiments, the frame body 32 and the connecting rod 33 can be an integrated structure. The frame body 32 can be welded in the branch pipe 2, or the frame body 32 can be fixed in the branch pipe 2 by other fasteners, for example, the frame body 32 can be fixed in the branch pipe 2 by threads.
[0056] In some embodiments, a support rod 34 is further arranged between the frame body 32 and the filter plate 31, the support rod 34 being uniformly distributed on the filter plate 31, and the support rod 34 being arranged in parallel with the connecting rod 33.
[0057] The support rod 34 is used to support the filter plate 31 to prevent the filter plate 31 from deforming.
[0058] Referring to Figs. 1 to 5 In some embodiments, the pollution box 22 is arc-shaped, the pollution box 22 is coaxially arranged with the branch pipe 2, and the pollution box 22 is welded to the branch pipe 2.
[0059] The pollution box 22 can also be arranged in the branch pipe 2 by other means. When the pollution box 22 and the branch pipe 2 are connected in a detachable manner, a sealing gasket should be arranged between the pollution box 22 and the branch pipe 2.
[0060] The above describes the subject technical scheme of the utility model and the corresponding details. It should be understood that the above description is only some embodiments of the subject technical scheme of the utility model, and some details can be omitted in the specific implementation.
