Abstract
The utility model relates to a ventilating device used below colliery, in particular to a connecting pipe for a fan. The connecting pipe solves the technical problem of incapability of quickly switching a main fan and a spare fan by the conventional fan connection device. The connecting pipe for the fan comprises a straight tee pipe made of steel or toughened glass, wherein the inner wall of a connecting place of two air inlet pipes of the tee pipe is hinged to a baffle, which is matched with the pipe diameter and is made of steel or toughened glass; the rotation axial direction of the baffle is vertical to a plane, on which the axis of each air inlet pipe and the axis of an air outlet pipe are located; an annular sealing rubber pad, which is matched with the baffle, is arranged between a position, which clings to the hinged place of the baffle, of the inner wall of each air inlet pipe of the baffle and the inner wall of the connecting place of the air inlet pipes and the air outlet pipe. According to the connecting pipe, by adopting the design of the straight tee pipe and the hinged baffle, the main fan and the spare fan are quickly switched, the switching time is quick, and the time loss can be negligible; the material is firm and durable, so that the ventilating quality is effectively guaranteed.
Description
Technical field
The utility model relates under colliery uses ventilation equipment, is specially a kind of fan connecting tube.
Background technique
Ventilation equipment under colliery, if blower fan is when breaking down, need to adopt a standby blower fan to be connected with original air channel, to guarantee that the ventilation condition (air quantity, wind speed etc.) under colliery meets related request at present.But current Placement wastes time and energy, can not realize fast conversion, even can have influence on the ventilation safety of down-hole.
Summary of the invention
The utility model is the technical problem that the current blower fan connection set of solution can not complete main air blower and standby fan switching fast, and a kind of fan connecting tube is provided.
The utility model is to adopt following technological scheme to realize: a kind of fan connecting tube, comprises a straight tee of being made by steel or toughened glass; The joint inwall of two air intake pipes of described three-way pipe is hinged with a baffle plate of being made by steel or toughened glass matching with caliber; The rotation of baffle plate is axially perpendicular to the axis place plane of air intake pipe and air outlet tube; The position that each air intake pipe inwall of described baffle plate is close to baffle plate hinged place all with between this air intake pipe and the inwall of air outlet tube joint is provided with the seal rubber pad of the ring-type matching with baffle plate.
As shown in Figure 1, main air blower is connected with the air intake pipe that is positioned at figure middle and upper part, and standby fan is connected with the air intake pipe of figure middle and lower part, and air outlet tube is connected with air channel; When main air blower is normally worked, baffle plate is opened by wind, baffle plate rotates around hinged place, and the seal rubber pad close contact of establishing with the air intake pipe that is arranged in figure below, by the air intake pipe sealing being connected with standby fan, main air blower is just communicated with air channel by straight tee, in air channel, carries air; When main air blower breaks down can not normally work time, start standby fan, the wind of standby fan blows to baffle plate at the seal rubber pad place establishing in the air intake pipe being connected with main air blower, baffle plate and seal rubber pad close contact, by this air intake pipe sealing, standby fan is just connected with air channel.Straight tee and baffle plate all adopt steel or toughened glass to make, and overall structure is very sturdy and durable, and deformation can not occur whole three-way pipe in ventilation process, have guaranteed to ventilate smooth and easy; The rotating shaft of baffle plate is axially vertical with the axis place plane of three-way pipe, has guaranteed that baffle plate can match air intake pipe is sealed up with seal rubber pad in rotation.Seal rubber pad, for ring dress, is arranged on the inwall of air intake pipe, and the baffle plate that rotation can be come blocks and realize the sealing of this air intake pipe.
Further, described same footpath three-way pipe comprises that two couple together and are the air intake pipe of U-shaped or V-type, and bottom centre U-shaped or V-type has the opening isometrical with air intake pipe, opening be connected with one with the isometrical air outlet tube of air intake pipe.
As shown in Figure 1, 2, two air intake pipes of described straight tee couple together as U-shaped, and U-shaped bottom opening also connects air outlet tube.Structural design U-shaped or V-type be conducive to the rotation of baffle plate and with the coordinating of air intake pipe.
The design that the utility model adopts straight tee and hinged baffle plate, has realized the quick conversion of main air blower and standby fan, and conversion time is fast, and time loss is negligible; Material therefor is durable, has effectively guaranteed the quality of ventilating.

Embodiment
A kind of fan connecting tube, comprises a straight tee of being made by steel or toughened glass; The joint inwall of two air intake pipes 1 of described three-way pipe is hinged with a baffle plate of being made by steel or toughened glass 2 matching with caliber; The rotation of baffle plate is axially perpendicular to the axis place plane of air intake pipe 1 and air outlet tube 3; The position that each air intake pipe 1 inwall of described baffle plate 2 is close to baffle plate hinged place 7 all with between this air intake pipe 1 and the inwall of air outlet tube 3 joints is provided with the seal rubber pad 4 of the ring-type matching with baffle plate 2.
Described same footpath three-way pipe comprises that two couple together and are the air intake pipe 1 of U-shaped or V-type, and bottom centre U-shaped or V-type has the opening isometrical with air intake pipe 1, opening be connected with one with the isometrical air outlet tube 3 of air intake pipe 1.
Described straight tee adopts toughened glass to make; In air outlet tube 3, be also provided with air velocity transducer 5.
Described air intake pipe 1 and air outlet tube 3 are positioned on the outer wall of the same side and are equipped with suspension ring 6.
Whether air velocity transducer 5 can detect the interior wind-force air quantity of airduct 3 normal, just can judge that accordingly whether the working condition of blower fan is normal; The three-way pipe that sees through toughened glass design can be observed the related data of air velocity transducer 5.Suspension ring 6 are for being fixed on the utility model specific position.Articulating point 7 is positioned at the inwall place that two air intake pipes 1 are connected, and is positioned on the two middle position, as shown in Fig. 1,2.
