Description
Technical Field
The utility model belongs to the air door field especially relates to a permanent air door.
Background
The mine air door is an important structure for ensuring safe production of a mine, is an important component of a ventilation system, can effectively ensure the stability of the ventilation system and reduce ineffective air leakage, but a drainage pipeline needs to be reserved when the mine air door is built, and the existing drainage pipeline always has large air leakage and can directly influence the stability of the ventilation system. In order to solve the problems, the existing common mode is to build a wind-blocking wall to reduce the problem of air leakage of an air door, the wind-blocking wall often influences the drainage of a ditch, the water and sludge are easily accumulated on the return air side of the air door ditch, long-time accumulated water can lead to rusting and corrosion of the air door, and the normal operation of the work can be influenced simultaneously, so that the potential safety hazard is caused.
Disclosure of Invention
The utility model provides a permanent air door, this air door have effectively solved the problem that the air door leaked under the prerequisite of guaranteeing normal drainage.
The technical scheme of the utility model is that: the utility model provides a permanent air door, includes the air door, the air door lower part is equipped with anti-water pipe device, anti-water pipe device is a drum, and drum one end is open, is located the air door inboard, and the other end is provided with the closing cap that is used for sealing the drum port, is located the air door air inlet side, the closing cap passes through the connecting rod and articulates on the drum.
The connecting rod is a C-shaped rod.
And the sealing cover is provided with a convex ring which is matched with the inner wall of the cylinder.
And the connecting rod is provided with a balance weight hanging ring for connecting a balance weight block.
The side of the cylinder sealing cover is an inclined plane.
One end of the connecting rod is fixedly connected with the sealing cover.
The diameter of the cylinder is 10-15 cm.
The utility model discloses simple structure, convenient to use has solved the problem of original air door drain pipe hourglass through setting up the anti-water pipe device in the air door lower part, and the anti-water pipe device on this application air door can match the hydraulic relation of ponding in adaptation air inlet side wind pressure and the return air side ditch according to actual conditions simultaneously, realizes the purpose of smooth drainage.

Detailed Description
Example 1
As shown in fig. 1 and 2, a permanent air door comprises an air door 1, a drainage ditch is not arranged at the lower part of the air door 1, a water return pipe device is fixedly connected to the lower part of the air door and is a cylinder 2, one end of the cylinder is open and is positioned on the inner side of the air door, a sealing cover 3 used for sealing a port of the cylinder is arranged at the other end of the cylinder and is positioned on the air inlet side of the air door, the sealing cover 3 is hinged to the cylinder through a connecting rod 4, the connecting rod is a C-shaped rod, one end of the connecting rod is fixedly connected with the sealing cover, a convex ring is arranged on the sealing cover 3, and the convex.
The utility model discloses a principle is, when the water pressure of air door ditch both sides is less than the wind pressure, can produce ponding in the return air side ditch, along with the increase of ponding in the ditch, water pressure also can constantly increase, when the water pressure of air door ditch both sides is greater than the wind pressure, ponding can break the closing cap under hydraulic effect, can be with the ponding discharge in the air door.
Example 2
In practical use, in some environments with small wind pressure at the air inlet side and large water drainage at the air return side, by using the scheme of the embodiment 1, the cylinder can push the sealing cover to drain water when water is accumulated slightly, so that the sealing cover is in an open state for a long time, the problem of air leakage of the air door still exists, and the following optimized structure can be adopted,
as shown in fig. 1 and 3, a permanent air door comprises an air door 1, wherein a water return pipe device is arranged on the lower portion of the air door 1, the water return pipe device is a cylinder 2, one end of the cylinder is open and is positioned on the inner side of the air door, a sealing cover 3 used for sealing the port of the cylinder is arranged on the other end of the cylinder and is positioned on the air inlet side of the air door, the sealing cover 3 is hinged to the cylinder through a connecting rod 4, the end portion of the cylinder on the sealing cover side is short and long at the top and at the bottom to form an inclined surface, the sealing cover is obliquely pressed on the end portion of the cylinder at the moment, the water pressure in the cylinder can be resisted by the weight of the sealing cover. Meanwhile, if the self weight of the sealing cover cannot completely and reasonably drain water, the connecting rod 4 is provided with a balance weight hanging ring 41, a balance weight block is connected to the balance weight hanging ring, and the drainage of the water return pipe is continuously adjusted through the weight of the balance weight block.
Example 3
Similarly, in some environments with large wind pressure at the air inlet side and small water pressure at the air return side, accumulated water in the cylinder is full, but the accumulated water cannot push the sealing cover open due to overlarge wind pressure and cannot realize drainage, the following optimized structure can be adopted,
as shown in figures 1 and 4, the permanent air door comprises an air door 1, a water return pipe device is arranged at the lower part of the air door 1, the water return pipe device is a cylinder 2, one end of the cylinder is open and is positioned at the inner side of the air door, the other end of the cylinder is provided with a sealing cover 3 for sealing the port of the cylinder and is positioned at the air inlet side of the air door, the sealing cover 3 is hinged on the cylinder through a connecting rod 4, the end part of the cylinder at the sealing cover side is long at the top and short at the bottom to form an inclined plane, the end surface of the cylinder is made into the inclined plane, so that the space between the sealing cover and the cylinder can be increased, the flow of drainage is increased, but also utilizes the dead weight of the sealing cover to resist the wind pressure, adjusts the opening of the sealing cover, realizes the purposes of draining water and preventing air leakage, and if the dead weight of the sealing cover still can not resist the wind pressure, the counterweight can be connected on the counterweight hanging ring 41 of the connecting rod, and the weight of the counterweight is utilized to further resist the wind pressure, thereby realizing the purposes of water drainage and wind leakage prevention.
Example 4
The connecting rod is of a crank arm structure, and the sealing and opening functions of the sealing cover to the cylinder end are realized.
