Abstract
The utility model discloses a natural ventilator. The natural ventilator is characterized by comprising a rotary portion and a duct base portion, wherein the rotary portion is installed on the upper portion of the duct base portion, the duct base portion comprises a duct (6) and a support group which is arranged inside the duct (6), the rotary portion comprises a main shaft (2) which is located an axial central axis of the duct (6), the upper end of the main shaft (2) is matched and connected with a top cover (4) through a bearing (3), the lower end of the main shaft (2) is fixedly connected with the duct (6) through the support group, the periphery of the top cover (4) is connected with one end of an arranged turbine blade (5), and the other end of the turbine blade (5) is connected with an upper edge of a ring pipe (9) which is sleeved on the outside of the duct (6). The natural ventilator has the advantages that the natural ventilator is subjected to one-time punch forming through stainless steel, corrosion resistant and acid-base resistant, a stainless steel duct reducing design and a dual ribbing method are adopted, roundness of bottom rings are guaranteed, sealing bearings are used, and the rotary resistance is small.
Description
Technical field
The utility model relates to a kind of ventilation unit, relates in particular to a kind of natural ventilator.
Background technology
Need air draft, exhaust in daily life or some production field, like market, warehouse and manufacturing workshop etc.Dirty, scorching air not only causes certain injury to people's health; Even because some workshops can produce a large amount of dust, as between flour lorry, aluminium powder workshop etc., dust accumulates to finite concentration sometimes; Might cause dust explosion in case naked light occurs, people's life is constituted a threat to.
Generally take at present to carry out timely ventilation and avoid taking place because of the unfavorable serious consequence that causes of ventilating to indoor; But there is complex structure in used air regenerating device, and is on the high side, implements to have relatively high expectations to wait deficiency; More distinct issues are to need power drive mostly; The explosion-proof specification requirement of Denging need be considered toward contact in the place that particularly dust concentration is had strict demand, and the enforcement difficulty is further strengthened.
The utility model content
The technical problem that the utility model will solve is that price is high to existing ventilation equipment complex structure, and it is high to implement requirement, needs power-actuated deficiency mostly, and a kind of natural ventilator is provided, and it has advantage simple in structure, as to need not power.
To achieve these goals, the utility model adopts following technical scheme:
A kind of natural ventilator; It comprises a rotating part and airduct base part; Said rotating part is installed in airduct base part top, and said airduct base part comprises the groups of holders in airduct and the airduct, and said rotating part comprises the main shaft that is positioned on the said airduct central axis; Said main shaft upper end is connected through bearing and top cover; The lower end is fixedly connected with airduct through groups of holders, and one week of said top cover edge is connected with the turbo blade that is provided with one end, and the turbo blade other end is connected with the endless tube top edge that is enclosed within the airduct outside.
Said endless tube lower limb is positioned at more than the airduct middle part; Said airduct foundation ring is provided with closing in, and sidewall is provided with at least one beading.
Said groups of holders comprises groups of holders I, groups of holders II, and said groups of holders I at right angles is connected to four supports between airduct inwall and the main shaft for angle in same plane.
Said groups of holders II is for being positioned at below the groups of holders I, and angle is 120 degree and is connected to three supports between airduct inwall and the main shaft in same plane.
The operation principle of the utility model
In said technical scheme, natural ventilator airduct and ventilating duct are passed through bolted, when gentle breeze blows the natural ventilator turbo blade; Turbo blade receives natural wind; Drive the rotation of natural ventilator rotating part, in ventilating duct, form draft, make ventilation effect be able to strengthen.
The beneficial effect of the utility model:
1, utilize stainless steel one time punching molded, anticorrosion, acid and alkali-resistance;
2, stainless steel airduct reducing design; Be provided with closing in, be provided with at least one beading, guarantee the foundation ring out of roundness;
3, use hermetically sealed bearing, rotary resistance is little.
Description of drawings
Fig. 1 is the structural representation of natural ventilator.
Wherein, 1. groups of holders I, 2. main shaft, 3. bearing, 4. top cover, 5. turbo blade, 6. airduct, 7. beading, 8. groups of holders II, 9. endless tube.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Embodiment 1:
Among Fig. 1, a kind of natural ventilator, it comprises a rotating part; With the airduct base part; Said rotating part is installed in airduct base part top, and said airduct base part comprises airduct 6 and the interior groups of holders of airduct, and said rotating part comprises the main shaft 2 that is positioned on said airduct 6 central axis; Said main shaft 2 upper ends are connected through bearing 3 and top cover 4, and the lower end is fixedly connected with airduct 6 through groups of holders.Said top cover one week of 4 edges is connected with the turbo blade that is provided with 5 one ends, and turbo blade 5 other ends are connected with endless tube 9 top edges that are enclosed within airduct 6 outsides.Endless tube 9 lower limbs are positioned at more than airduct 6 middle parts, and the airduct foundation ring is provided with closing in; Sidewall is provided with twice beading 7.
Groups of holders comprises groups of holders I 1, and groups of holders II 8, and said groups of holders I 1 at right angles is connected to four supports between airduct 6 inwalls and the main shaft 2 for angle in same plane.Groups of holders II 8 is for being positioned at below the groups of holders I 1, and angle is 120 degree and is connected to three supports between airduct 6 inwalls and the main shaft 2 in same plane.
Though the above-mentioned accompanying drawing that combines is described the specific embodiment of the utility model; But be not restriction to invention/the utility model protection domain; One of ordinary skill in the art should be understood that; On the basis of the technical scheme of the utility model, those skilled in the art need not pay various modifications that creative work can make or distortion still in the protection domain of the utility model.
