Description

Technical Field

[0001] The utility model belongs to the technical field of underground ventilation, and in particular relates to an assembled simple air volume regulating damper for coal mines. Background Art

[0002] According to the current needs of the mine and relevant regulations, ventilation facilities need to be built in some underground connecting tunnels for people and vehicles to pass through. Therefore, it is necessary to reasonably distribute air to the tunnel to meet the needs of people and vehicles. The traditional damper is a whole iron sheet, and the air volume is generally adjusted through the reserved adjustment port on the damper wall. However, the adjustment port on the damper wall is easy to deform and has inconsistent specifications. Once damaged, the maintenance cost is high. For this reason, we proposed an assembled simple air volume adjustment damper. Utility Model Content

[0003] An object of the present invention is to solve at least the above problems and to provide at least the advantages which will be described below.

[0004] The utility model provides the following technical solutions: an assembled simple air volume regulating damper for a coal mine, the damper comprising a door leaf, the door leaf comprising a door leaf frame and a door panel, a plurality of door panels being fully spread on the door leaf frame in the form of a rectangular array, the door panel being mounted on the door leaf frame through an independently detachable structure; the door leaf frame being connected to the door frame through a hinge, a cylinder being connected between the door leaf frame and the door frame to enable the damper to be opened and closed as a whole.

[0005] Furthermore, the door panels are close to each other on the left and right sides, and the upper and lower sides of the door panels are installed on the door leaf frame by bolts.

[0006] Furthermore, the door panel is a rectangle, the long side of the rectangle is vertical and the short side is horizontal; a supporting cross bar is provided on the door leaf frame in the middle of the long side of the rectangle.

[0007] Furthermore, the door panels on the damper are divided into two rows, an upper row and an lower row, and the door panels in the upper row and the lower row are vertically aligned.

[0008] Furthermore, the damper comprises two door leaves which open opposite to each other.

[0009] Compared with the prior art, the advantages of the present invention are:

[0010] The utility model provides a coal mine assembled simple air volume regulating damper. On the basis of the original whole door, the whole iron sheet of the door leaf is changed into a plurality of small iron sheets spliced ​​together. When adjusting the air volume of the local area roadway, an appropriate amount of small iron sheets are used according to actual needs, and screws and door leaf frames are used to fix them, so as to achieve the purpose of quickly adjusting the air volume of the local area roadway. It is easy to use, reusable, low cost and high work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a structural schematic diagram of the utility model.

[0012] In the figure: 1-door leaf frame; 2-door panel; 3-hinge; 4-bolt; 5-support cross bar. DETAILED DESCRIPTION

[0013] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0014] like Figure 1 As shown: a coal mine assembled simple air volume regulating damper, the damper includes two opposing door leaves, the door leaves include door leaf frames 1 and door panels 2, a plurality of door panels 2 are fully spread on the door leaf frames 1 in the form of a rectangular array, and the door panels 2 are installed on the door leaf frames 1 through an independently detachable structure; the door leaf frames 1 are connected to the door frame through hinges 3, and a cylinder is connected between the door leaf frames 1 and the door frame to open and close the damper as a whole.

[0015] The door panels 2 are cut from sheet iron, and the left and right door panels 2 are close to each other. The upper and lower sides of the door panels 2 are mounted on the door leaf frame 1 by bolts 4, and are easy to disassemble and assemble.

[0016] When in use, the two door leaves are opened or closed by the cylinder, and the appropriate number of door panels 2 are disassembled and installed according to the required air volume of the local area lane.

[0017] The door panel 2 is a rectangle with the long side of the rectangle being vertical and the short side being horizontal. A support cross bar 5 is provided on the door leaf frame 1 in the middle of the long side of the rectangle, and the support cross bar 5 supports the door panel 2 to prevent the door panel 2 from being deformed by wind pressure.

[0018] The door panels 2 on the damper are divided into two upper and lower rows, and the door panels 2 in the upper and lower rows are vertically aligned.

[0019] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
