Description
Technical Field
The utility model relates to a fan technical field, in particular to special rolling slats door of negative-pressure air fan air intake.
Background
The fan is a machine which can increase the gas pressure and discharge the gas by means of the input mechanical energy, and is widely used for ventilation, dust exhaust and temperature reduction of breeding houses, factories, mines, tunnels and buildings; because livestock, personnel and equipment are more in livestock and poultry houses, plants or large buildings, a plurality of fans are required to be arranged on the outer wall for indoor ventilation, shutters are generally arranged at the air inlets of the fans, and the shutters are automatically closed after the fans are closed, so that rain and snow are prevented from entering the room.
However, the air inlet of the fan is connected with the louver, and the defects that ① louvers are arranged at the position of the air inlet, the number of supporting frames is large, air flow is disturbed, wind resistance is formed, ② louver assemblies are large, the number of fit clearance gaps is large, the heat preservation effect is poor, and ③ louver assemblies have large friction with air, so that noise pollution is caused.
SUMMERY OF THE UTILITY MODEL
The utility model overcomes the deficiencies in the prior art, a special rolling slats door of negative-pressure air fan air intake is provided.
In order to solve the technical problem, the utility model discloses a realize through following technical scheme:
the utility model provides a special rolling slats door of negative-pressure air fan air intake, includes the curtain piece and sets up the guide rail in the curtain piece left and right sides, the curtain piece lower extreme is connected with the floorbar, the curtain piece left and right sides respectively is equipped with a plurality of end clamps, curtain piece upper end connection spool, horizontal equipartition has a plurality of sheaths on the spool, the tail stopper is connected on the spool right side, the motor drive wheel is connected to the spool left end, the tubular motor is connected to the motor drive wheel, the motor crown wheel is connected to the tubular motor, motor crown wheel left side, tail stopper right side all are connected with the end cover board, all be connected with guider on the end cover board.
Preferably, the bottom beam is connected with a bottom beam rubber strip.
Preferably, the sheath is annular.
As a preferred scheme, wool tops are connected to two sides of the guide rail groove.
Preferably, a protective cover is arranged outside the reel.
Compared with the prior art, the beneficial effects of the utility model are that: 1. the special rolling door for the fan does not generate any blocking image to the air inlet of the fan in the opening state, and the efficiency of the fan is ensured to the maximum extent; 2. the special rolling door for the fan is easy to install, less in maintenance and convenient to operate, and does not need maintenance of professional personnel. 3. The special rolling shutter door for the fan has no pollution, low noise, no damage to the environment and low carbon; 4. the special rolling door for the fan is in a static state in the running state of the fan, and does not produce any noise pollution.
Drawings
The invention will be described in further detail with reference to the following detailed description and accompanying drawings:
FIG. 1 is a schematic sectional view of the front view of the present invention;
in the figure: the device comprises a curtain sheet 1, a bottom beam 2, a bottom beam adhesive tape 3, an end clamp 4, a reel 5, a motor driving wheel 6, a tubular motor 7, a motor crown wheel 8, a protective cover 9, an end cover plate 10, a guide device 11, a tail plug 12, a protective cover 13, wool tops 14 and a guide rail 15.
