Description

One-way wall drainage pipe fitting

technical field

The utility model relates to a drainage pipe fitting, in particular to a one-way wall drainage pipe fitting.

Background technique

At present, when building walls, drainage holes of a certain size are generally left at the root of the wall, but on the wall of the substation, it is necessary to add a net in the drainage hole to prevent small animals from entering the substation. Safety poses a huge threat, but if the mesh of the added protective net is too large, it will not be able to block the entry and exit of small or young animals. Smooth, a large amount of rainwater deposition, backflow and other problems in the substation will bring pressure to the substation's flood control.

Utility model content

The technical problem to be solved by the utility model is to provide a one-way wall drainage pipe fitting with simple structure, smooth drainage and the ability to prevent small animals from entering.

The utility model adopts the following technical solutions:

The utility model comprises a pipe fitting body with a rectangular section, a rotating shaft arranged in the pipe fitting body, and a baffle plate sleeved on the rotating shaft and capable of rotating on the rotating shaft. The vertical plate connecting the front end of the base plate and the rear end of the base plate is composed of a vertical plate, the rotating shaft is arranged at the upper position corresponding to the vertical plate in the pipe fitting body, the lower end of the baffle plate is in contact with the vertical plate, and the rotating shaft is sleeved with As for the torsion spring, an opening is provided in the middle part of the top end of the baffle, and the torsion spring is sheathed on a section of the rotating shaft corresponding to the opening.

The positive effect of the utility model is as follows:

When the utility model is used, since the baffle can only swing in one direction, the rainwater or accumulated water in the substation can be washed away from the baffle and discharged outside the courtyard, and small animals outside can be prevented from entering the substation and threatening the power grid. At the same time, it can also prevent rainwater Backflow into the substation will cause pressure on the flood control of the substation; since the torsion spring is sleeved on the rotating shaft, when there is no water flow hitting the baffle, the force of the torsion spring can help the baffle return to its original position, and the resistance of the torsion spring to the baffle can be reduced. Prevent the baffle from swinging continuously under the action of wind, causing noise, and also prevent small animals from opening the baffle and entering the substation.

Since the stepped bottom plate of the drainage pipe fitting is composed of the front end of the bottom plate, the rear end of the bottom plate, and the vertical plate connecting the front end of the bottom plate and the rear end of the bottom plate, the bottom plate of the main body of the pipe fitting can be stamped from a steel plate with uniform thickness, which is simple and saves materials; the stepped bottom plate Prevents sediment buildup from clogging drain fittings.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

As shown in Figures 1 and 2, a one-way wall drainage pipe fitting is made of steel plate, which includes a pipe fitting body 1 with a rectangular cross-section, a rotating shaft 2 arranged in the pipe fitting body 1, and a shaft 2 sleeved on it and can be The baffle plate 3 rotating on the rotating shaft 2, as shown in Figure 2, the bottom plate of the pipe fitting body 1 is composed of the front end 11 of the bottom plate, the rear end 12 of the bottom plate, and the vertical plate 13 connecting the front end 11 of the bottom plate and the rear end 12 of the bottom plate. The front end 11 of the bottom plate is higher than the rear end 12 of the bottom plate, the rotating shaft 2 is set in the upper position corresponding to the vertical plate 13 in the pipe body 1, and the lower end of the baffle plate 3 is in contact with the vertical plate 13 , so that the baffle 3 can only swing in the direction of the drain port 5, realizing the one-way opening function, and compared with the straight bottom plate with the boss corresponding to the baffle 3, the stepped bottom plate can prevent Sediment and debris accumulate in the drainage fittings, blocking the drainage channels.

As shown in accompanying drawings 3 and 4, a torsion spring 6 is sleeved on the rotating shaft 2, and an opening 31 is provided in the middle of the top end of the baffle plate 3, and the torsion spring 6 is sleeved in a position corresponding to the opening 31. On a section of the rotating shaft 2, one end of the torsion spring 6 is against the top of the pipe body 1, and the other end is against the side of the baffle 3 facing the drain 5, so that the force of the torsion spring 6 becomes the swing of the baffle 3 toward the drain 5. The resistance can help the baffle return to its original position, and the resistance of the torsion spring to the baffle can prevent the baffle from swinging continuously under the action of wind, causing noise, and can also prevent small animals from pushing the baffle to enter the substation.

When building the enclosure wall of the substation, the utility model is built in the root of the wall, with the water inlet 4 facing inward and the drain outlet 5 facing outward. Under the impact of the impact, the baffle 3 swings towards the drain port 5, and the water flow is discharged from the drain pipe. When there is no water impact, the baffle 3 returns to its original position under the action of its own gravity and the force of the torsion spring 6, and the drain pipe is blocked. To prevent small animals from entering the courtyard and posing a threat to the safety of the power grid; when there is a large amount of water outside, the baffle 3 will block the drainage pipes under the impact of the water flow entering from the drain 5 to prevent backflow to the substation and cause flood control in the substation. Pressure; when there is no water flow, due to the effect of the torsion spring 6, the baffle plate 3 can be prevented from constantly swinging under the effect of wind force, causing sound, and it can also prevent small animals from poking the baffle plate 3 to enter the substation.

The implementations described above are only preferred embodiments of the present invention, rather than an exhaustive list of feasible implementations of the present invention. For those skilled in the art, any obvious changes made without departing from the principle and spirit of the utility model should be considered to be included in the protection scope of the claims of the utility model. the
