Abstract
An unpowered jet flow air-intake window is characterized in that an air-intake back plate is mounted on the inner side of an air-intake window frame, a connecting shaft is mounted between the lower side of the back plate and the lower side of the air-intake window frame, a controlling tension spring is mounted on the upper portion of the back plate, and one end of the tension spring is connected with the air-intake window frame. By the unpowered jet flow air-intake window, the problems that a negative pressure controller and a motor-drive type jet flow air-intake system are high in cost and complex in mounting are solved, and the unpowered jet flow air-intake window is widely applicable to mounting and using in livestock farms and animal housings.
Description
Technical field
The present invention relates to air control device field in plant's poultry house, is a kind of for the air intake window of circulated air is provided in totally-enclosed poultry house specifically.
Background technology
The air inlet facility that plant's poultry house is used at present, all by air intake window, negative pressure controller and CD-ROM drive motor, form a gas handling system, by negative pressure value in negative pressure controller collection house, to CD-ROM drive motor, send signal, control air intake window air inlet baffle plate and open amplitude adjusted induction air flow ratio.Its shortcoming is that cost is high, installation is complicated, and needs power consumption operation and often safeguard.
Summary of the invention
The present invention be to solve negative pressure controller and CD-ROM drive motor formula jet gas handling system, and cost is high, complicated problem, a kind of jet air intake window without power of design are installed.
Technical scheme of the present invention is, a kind of unpowered jet air intake window, its special character is, air inlet verge board is housed on the inside of air intake window housing, verge board below with between air-inlet window housing following connecting axle is housed, control extension spring is equipped with on the top of verge board, and the other end of extension spring is connected with air intake window housing.
When the inside and outside air pressure difference of house increases, outdoor air promotes verge board and elongates extension spring, and air inlet port is increased, and intake velocity is accelerated; When house inner air and outer air pressure reduction reduces, outdoor air reduces the thrust of verge board, and extension spring is shunk and pulled verge board, and air inlet port is diminished, and intake velocity slows down.
Technique effect of the present invention is that employing technique scheme, can realize jet air intake window device in closed type domestic animal house a kind of simple in structure, easy to operate.It by the flexible verge board that pulls of extension spring, changes the size of air inlet port according to the variation of house inner air and outer air pressure reduction, and fresh air jet is entered in poultry house, has realized unpowered jet air inlet, has greatly saved cost of production, has reduced energy consumption.
Accompanying drawing explanation
Fig. 1 is structural front view of the present invention, and the accompanying drawing that makes an abstract.
In the drawings, 1 air intake window housing, 2 extension springs, 3 verge boards, 4 connecting axles.
The specific embodiment
Below in conjunction with accompanying drawing example, the present invention is further described.
As shown in the figure, air inlet verge board 3 is housed on the inside of air intake window housing 1, verge board 3 below with air-inlet window housing 1 below between connecting axle 4 is housed, control extension spring 2 is equipped with on the top of verge board 3, the other end of extension spring 2 is connected with air intake window housing 1.
When the inside and outside air pressure difference of house increases, outdoor air promotes verge board 3 and elongates extension spring 2, and air inlet port is increased, and intake velocity is accelerated; When house inner air and outer air pressure reduction reduces, outdoor air reduces the thrust of verge board 3, and extension spring 2 is shunk and pulled verge board 3, and air inlet port is diminished, and intake velocity slows down.
