Detailed Description

The present invention is further described in detail below with reference to the drawings so that those skilled in the art can implement the invention with reference to the description.

As shown in fig. 1-3, the utility model provides a rain discharging device for building, include: the upper end part of the rain drainage pipeline 2 is provided with a stepped hole 201, and the rain drainage pipeline 2 is used for draining accumulated water on the roof;

the cover plate 1 is detachably arranged at the end part of the rain drainage pipeline 2;

the cover plate 1 is also provided with a plugging mechanism which is arranged in the stepped hole 201, when rainwater accumulates, the plugging mechanism descends to discharge the rainwater, and when no rainwater exists, the plugging mechanism is attached to the retaining ring 104 on the cover plate 1;

the cover plate 1 is further provided with a drainage groove 101, the drainage groove 101 is used for guiding rainwater to enter the rainwater drainage pipeline 2, and the drainage groove 101 is also used for reducing acting force of wind power on the rainwater drainage pipeline 2;

the drainage grooves 101 are lead-in chamfers arranged on the inner edges of the cover plate 1, and rainwater can smoothly enter the rainwater drainage pipeline 2 by the lead-in chamfers.

The working principle is as follows: the cover plate 1 is fixed at the end part of the rain drainage pipeline 2 through fixing parts such as bolts, and can be replaced at any time if the cover plate 1 is damaged, when wind blows, strong wind enters the rain drainage pipeline 2, the rain drainage pipeline 2 can vibrate, the service life of the rain drainage pipeline 2 is influenced, the plugging mechanism on the cover plate 1 can block the wind power, the acting force of the wind power on the rain drainage pipeline 2 is prevented, and the rain drainage pipeline 2 is prevented from being damaged due to vibration; when raining, rainwater enters the upper part of the plugging mechanism through the drainage groove 101, the plugging mechanism descends due to the gravity action of the rainwater, the rainwater is discharged along the rainwater discharging pipeline 2, and when no rainwater exists, the plugging mechanism is attached to the cover plate 1 to prevent strong wind from entering the rainwater discharging pipeline 2; it can be understood that when wind blows, wind power is blown against the roof, not blown up and down, when strong wind sweeps across the cover plate 1, the wind power which can act on the plugging mechanism is very small by arranging the drainage grooves 101, and further, the drainage grooves 101 can reduce the acting force of the wind power on the rain drainage pipeline 2 besides guiding rainwater to enter the rain drainage pipeline 2; through setting up retaining ring 104, can make plugging mechanism and retaining ring 104 closely laminate, play sealed effect, prevent that external wind-force from entering into row rain pipe 2 in, simultaneously, also can prevent plugging mechanism and row rain pipe 2 break away from.

The plugging mechanism comprises: the baffle plate 103 is arranged below the retainer ring 104, the guide post 102 is arranged above the baffle plate 103, the guide post 102 is in sliding fit with the retainer ring 103, the compression spring 105 is arranged below the baffle plate 103, and the compression spring 105 is attached to the stepped hole 201.

The working principle is as follows: external rainwater enters the upper part of the baffle plate 103 along the drainage groove 101, the baffle plate 103 descends under the guidance of the guide post 102 due to the gravity action of the rainwater, the compression spring 105 is further compressed, and after the rainwater descends, the external rainwater enters the rainwater drainage pipeline 2 along a gap between the baffle plate 103 and the rainwater drainage pipeline 2, so that the purpose of draining the rainwater is achieved; when no rainwater exists, the compression spring 105 can bounce the baffle plate 103 due to the spring force of the compression spring 105, so that the baffle plate 103 is attached to the check ring 104 and sealed, and the aim of preventing the wind power from draining the rainwater in the pipeline 2 is fulfilled.

A spiral groove 106 is provided on the lower circumferential side of the baffle plate 103, the pitch of the spiral groove 106 is 1mm smaller than the pitch a of the compression spring 105, and the compression spring 105 is screwed into the groove 106.

The working principle is as follows: as shown in FIG. 3, in order to prevent the compression spring 105 from being separated from the baffle plate 103, the compression spring 105 is screwed into the baffle plate 103, a spiral groove 106 is provided, the pitch of the groove 106 is smaller than the pitch A of the compression spring 105 by 1mm, when the compression spring 105 is screwed into the baffle plate 103, the spring wire of the compression spring 105 enters the groove 106, and meanwhile, the spring wire can be slightly deformed, the slight deformation can enable the compression spring 105 to clamp the groove 106, and the slight deformation does not influence the performance of the compression spring 105 and is convenient for an operator to install.

The number of guide posts 102 is four.

The working principle is as follows: the guide posts 102 mainly play a role in guiding the baffle 103, the baffle 103 and the retainer ring 104 are attached to each other, the baffle 103 is prevented from deviating, meanwhile, the four guide posts 102 are uniformly arranged around the baffle 103 as the circle center, and besides the guiding function, external sundries can be blocked, and when rainwater is discharged, the external large sundries can be prevented from entering the rainwater discharging pipeline 2 through the blocking function of the guide posts 102, and the rainwater discharging pipeline 2 is prevented from being blocked.
