Detailed Description

The utility model provides a tornado demonstration equipment, for making the utility model discloses a purpose, technical scheme and effect are clearer, clear and definite, and it is right that the following embodiment is lifted with reference to the attached drawing the utility model discloses do further detailed description. It should be understood that the detailed description and specific examples, while indicating the invention, are given by way of illustration only.

As shown in fig. 1, fig. 1 is a schematic structural diagram of a tornado demonstration device. It includes: a smoke generating device 10, an air supply device 20; the smoke generating device 10 comprises a smoke machine 110 and a smoke collecting box 120 connected with the smoke machine 110; the air supply device 20 comprises a fan 210 and a vertically arranged diversion air pipe 220 connected with an air outlet of the fan 210; the diversion air pipes 220 are symmetrically arranged around the smoke generating device 10; air outlet holes 2201 are uniformly formed in the pipe wall of the diversion air pipe 220 facing one side of the smoke generating device.

The smoke is supplied by the smoke machine 110 and sent into the smoke collecting box 120, smoke outlets are densely distributed at the top of the smoke collecting box 120, and the smoke is emitted from the smoke outlets. The blower 210 arranged around the smoke collection box blows air, the air is sent out through the air outlet 2201 on the diversion air pipe 220 to form cyclone, smoke emitted from the smoke collection box is blown up in a rotating mode from the bottom, and formation of tornado is simulated.

In one or more embodiments, the smoke collection box 120 includes a smoke inlet 1201 (not shown) disposed in a side wall of the smoke collection box, and a smoke outlet 1202 disposed at a top of the smoke collection box. For example, the smoke collecting box 120 is a cylinder, and regular or irregular smoke outlets are arranged on the top of the cylinder. The smoke outlet can be snowflake-shaped, so that the generated smoke can uniformly emerge.

Further, the smoke inlets 1201 of the smoke collecting box 120 are uniformly arranged on the side wall of the smoke collecting box 120, for example, six smoke inlets may be arranged diagonally at an interval 30. The smoke supplying device is provided with six smoke machines, and can be divided into three groups during normal use, and the smoke machines of the three groups supply smoke alternately, so that the smoke collecting box can supply smoke uninterruptedly.

In one or more embodiments, the number of the diversion air ducts 220 is four, and the diversion air ducts are erected around the smoke collection box through fixed supports fixed on the ground. The bottom of the diversion air pipe is provided with an air inlet (not marked in the figure), and the air inlet is connected with the blower. It is arbitrary adjacent can couple together through connecting piece 230 between the top of water conservancy diversion tuber pipe 120 and fix, in addition connecting piece 230 can be with the tuber pipe that water conservancy diversion tuber pipe 120 specification is the same, be UNICOM each other between each water conservancy diversion tuber pipe, and the air outlet that sets up on the tuber pipe of upper end is vertical decurrent, so set up can form the wind curtain wall around the smoke-collecting box, can block the influence of environmental wind, also can make the quick formation of the tornado of simulation simultaneously.
