Abstract
The utility model relates to a roof ventilator driven by wind or electricity, which mainly utilize the outdoor wind power to naturally exhaust the wind and utilize an electric ventilator to exhaust the wind in an auxiliary way, being a roof ventilator which can save the energy and can guarantee the ventilation effect, having the application for ventilation of factories and other buildings. The roof ventilator driven by wind or electricity can integrate the advantages of a wind cowl and the roof ventilator. The ventilator is arranged in a wind-shield cover. The operation of the roof ventilator can be adjusted by a wind control switch and a sliding tube. The wind can be naturally exhausted by the negative pressure formed by the wind-shield cover at the time of windy; the ventilator can be automatically started by the wind control switch at the time of windless. The utility model is high efficient energy-saving product, and the average power consumption of unit wind exhausting amount is just the 20-30% of that of a general ventilator.
Description
Wind-force electric power dual-purpose roof ventilator is utilizing the outdoor wind-force natural exhaust, and the air draft of electrically ventilating machine is auxilliary; Not only energy-conservation but also guarantee the roof ventilation device of ventilation effect.Be used for factory and various constructure ventilation.
Fig. 1 is the existing schematic diagram that is installed in all kinds of blast caps (cylindrical ventilator, Ball-shape wind exhaust cover) on the roof, and it is to be fixed on the short tube bearing (1a) with connector (5a) by windshield (2a), and rain shield (3a) is installed in the windshield (2a) and constitutes.When outdoor distinguished and admirable around the blast cap time, around blast cap, form negative pressure, room air be sucked out drain into outdoor.All kinds of blast caps do not have the mechanical exhaust device of ventilation blower class.
Fig. 2 is the schematic diagram of existing powerroof ventilator, and it is that screening by ventilation blower (6b), motor (7b) and motor is installed in short tube bearing (1b) every cover (12b) and goes up formation.The driven by power ventilation blower drains into room air outdoor.Various powerroof ventilators do not have and can utilize outdoor wind-force to carry out the device of the windshield class of gravity-flow ventilation.
Though blast cap can utilize the outdoor wind-force natural exhaust expeditiously, when outdoor when calm exhaust air rate then reduce a lot, instability can not satisfy the air-conditioning requirement in many places.Though powerroof ventilator and alloytype ventilation blower thereof can guarantee to stablize air draft, consumed power.
The purpose of invention is to develop a kind ofly can save the novel roof ventilation device that a large amount of electric energy can guarantee ventilation effect again.
Fig. 3 is the schematic diagram of the wind-force electric power dual-purpose roof ventilator of invention, windshield (2) is fixed on the short tube bearing (1) with connector (5), ventilation blower (6) and motor (7) are installed in the interior rain shield of windshield (2) (3) and are installed in ventilation blower (6), the top of motor (7) and short tube bearing (1), sliding tube (4) is sleeved on the suitable for reading of short tube bearing (1), sliding tube lowering or hoisting gear (9) be installed in the windshield (2) or short tube bearing (1) on, one end is connected with sliding tube (4), the other end and lever weight or electromagnetism, electric device connects, shut off valve (11) is installed in the short tube bearing (1), and the wind control switch (10) of control ventilation blower (6) start-stop is fixed on the ventilator or place in its vicinity independently is installed.
The ventilation process that is installed in the wind-force electric power dual-purpose roof ventilator on the roof is as follows: outdoor when having wind and mean wind speed at the appointed time to be higher than the higher limit that wind control switch (10) sets up wind control switch (10) do not start ventilation blower (6), sliding tube (4) is inserted in the short tube bearing (1), shown in solid line among Fig. 3, because outdoor wind causes negative pressure inside and outside roof ventilator, room air is inhaled into from short tube bearing (1) end opening, outdoor through sliding tube (4) the upper and lower opening discharge to windshield (2) suitable for reading, roof ventilator is in the natural exhaust stage.When outdoor calm or mean wind speed is lower than the lower limit of regulation, just, exhaust air rate prescribes a time limit when reducing to the following of regulation, wind control switch (10) starts ventilation blower (6) air draft automatically, sliding tube lowering or hoisting gear (9) is under wind-force or electric power effect, sliding tube (4) rising is enclosed within the blade exterior of ventilation blower (6), position as shown in phantom in Figure 3, under the draft of ventilation blower, room air sucks through ventilation blower (6) and sliding tube (4) is suitable for reading drains in the windshield (2) from short tube bearing (1) end opening, drain into outdoorly again through the upper and lower opening of windshield (2), roof ventilator has just entered the mechanical wind stage.Blow again and mean wind speed when being higher than higher limit when outdoor, wind control switch (10) just stopped ventilation blower (6) when just natural ventilation rate can meet the demands, sliding tube (4) landing automatically is inserted in the short tube bearing (1), roof ventilator has entered the natural exhaust stage again, so circulation is more than, and room air is continuously discharged outdoor.
The short tube bearing (1) of wind-force electric power dual-purpose roof ventilator be aspiration channel and bearing aggregate its suitable for reading be flat mouthful or outward flanging; End opening is the flange dish type, can make the dish type of downward flange for the end opening that prevents to seep water.Windshield (2) is the main member that utilizes wind energy, and its inside is hollow, and upper and lower opening is opened wide, and housing case is tubular, taper, sphere or many prismatics, be fix or rotate.
The short tube bearing (1) of wind-force electric power dual-purpose roof ventilator, windshield (2), rain shield (3) and sliding tube (4) are with metal material or resinous material and the making of glass fibre inorganic reinforcement such as fiberglass, plastics such as sheet metal, aluminium sheets.
The ventilation blower (6) of wind-force electric power dual-purpose roof ventilator is installed in the windshield (2) and the top of short tube bearing (1), is maybe can moving up and down of fixing; Also can be installed in the inside of short tube bearing (1) to the ventilation blower (6) of heavy caliber roof ventilator, at this moment not sliding tube (4) and lowering or hoisting gear (9) thereof.
The average power consumption of roof ventilator unit's exhaust air rate of invention only is 20～30% of a general powerroof ventilator, is energy-efficient equipment.
