Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vinyl house ventilation system and a vinyl house ventilation system using the same.

The present invention relates to an opening and closing apparatus for a ventilation window installed to open and close a predetermined area of a greenhouse for circulating air, and more particularly, it is possible to open and close a ventilation window semi-automatically, And a vinyl house ventilation system using the same.

Greenhouse is an important horticultural facility for cultivating crops, and its installation cost is cheap and easy to construct, which is widely used in farmhouses. 1 is a perspective view showing the appearance of a conventional plastic greenhouse. Referring to FIG. 1, a typical vinyl house currently used is composed of a vinyl house having a single structure or a double-structure vinyl house composed of an outer vinyl house 100 and an inner vinyl house 200 as shown in FIG. 1 .

In the conventional vinyl house, a ventilation window for air circulation is formed in the lower region along the longitudinal direction of both sides, because the opening and closing operations are possible only when the ventilation window is installed at a height at which the operator can reach out. Accordingly, the vinyl sheet 101 surrounding the vinyl house frame has a very simple structure in which the vinyl sheet located in the lower region of the vinyl sheet 101 is rolled up to form a vent in the lower region.

However, the conventional vinyl house ventilation system has a problem in that the air circulation is not smooth due to its structure, so that the temperature and humidity in the plastic greenhouse can not be controlled properly. Also, each time the ventilation window is opened, It is necessary to fix them by using a cord or the like, which is disadvantageous in discomfort and troubles in every ventilation.

In order to improve the disadvantages of such a conventional vinyl house ventilation system, in the prior art 1 (Korean Unexamined Patent Publication No. 2005-0005505), a winding rod 9 is installed at the lower end portion of the ventilating vinyl 7 as shown in FIG. 2, (9) is connected to a drive shaft provided with a handle (11), and the handle (11) is rotated to wind the ventilating vinyl on the winding rod so as to roll up the vinyl house ventilating vinyl switch.

However, if the wind-up system is used to roll up the ventilation window (i.e., the ventilation vinyl) by using the winding rod as in the prior art document 1, the vinyl sheet (i.e., the ventilation vinyl) is unevenly wound and the load is biased to one side of the opening / There is a problem that the rod or the vinyl house frame is bent or broken, and particularly, there is a problem that strong wind is blown or the vinyl sheet wound in the rain is torn or damaged.

However, the first thing to consider when installing ventilation windows in vinyl houses is that there is not enough room to install. Particularly, in the case of the double structure greenhouse, there is a problem that the space for installing the ventilation window is not sufficient. In the case of the double-structured vinyl house, the space between the outer vinyl house 100 and the inner vinyl house 200 formed at the entrance and the exit side of the vinyl house is approximately 1.5 m, so there is a free space. There was a problem in that the space between the 200 and the outer plastic house 100 (approximately within 70 cm and less than 1 m) was not applicable to opening and closing ventilation windows used in greenhouse windows.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is an object of the present invention to provide a ventilation window opening / closing device capable of automatically controlling a ventilation window installed to open and close a ventilation hole, The present invention provides a vinyl house ventilation opening and closing apparatus and a plastic house ventilation system using the same, which can fundamentally prevent a conventional ventilation window or frame damage problem due to an external environment while being capable of opening and closing operations very conveniently.

In addition, another object of the present invention to provide a vinyl house ventilation window opening and closing device and a vinyl house ventilation system using the same can be easily installed in a double-structured vinyl house in which the inner vinyl house and the surgical vinyl house in a narrow space in the ceiling portion. It is.

It characterized in that it comprises a first driven rod formed to.

According to the vinyl house ventilation window opening / closing apparatus and the vinyl house ventilation system using the same, it is possible to open and close the ventilation window automatically (semi-automatic) from a long distance, so that the ventilation window can be installed in the upper region of the plastic house. Accordingly, the convenience of the vinyl house air circulation operation can be greatly improved, temperature and humidity can be controlled by smooth air circulation, and the inside environment of the vinyl house can be maintained in an optimal state suitable for the growth of crops.

Further, even when the ventilation window is opened, there is a remarkable effect that it is possible to fundamentally eliminate the problem that the ventilation window or the frame is torn or damaged due to the external environment as in the prior art.

In addition, it has become possible to provide the elasticity that the window of the ventilation window can be formed of a plastic material or a glass material instead of a vinyl material, if necessary.

In addition, the two racks can be driven through one pinion, and the rack and the slide bar can be opened and closed by an indirect drive system in which a driven rod is interlocked with the slide bar. Thus, a direct drive system using an electric motor and a piston, There is an advantage that the problems of the rotating device (i.e., motor size due to high torque, etc.) can be eliminated.

The apparatus for opening and closing the ventilation window according to the present invention includes a pinion 157, a driver, a first rack 161, a second rack 163, a first slide bar 165, a second slide bar 167, 171), a second driven rod (173), and a suspension device.

The pinion 157 of the present invention is a small gear having a small number of teeth among a pair of gears meshed with the first rack 161, and is formed to be capable of forward rotation and reverse rotation under the control of a driver.

For reference, the term " forward rotation "used in the present invention refers to the rotation of the pinion 157 in the counterclockwise direction on the basis of FIG. 4 and the" reverse rotation " Quot;

The forward and reverse rotations of the pinion 157 are generated and controlled by a driver physically connected to the pinion 157. The driver according to the preferred embodiment of the present invention includes a pulley 151, a chain belt 153, 155).

The pulley 151 is formed in the shape of a circular wheel so that the wheel is rotatable with respect to the central axis, and the outer periphery of the pulley 151 is connected to a chain belt 153 formed by successively forming metal rings.

The drive shaft 155 is a component that connects the pulley 151 and the pinion 157 so that the motion of the pulley 151 is interlocked with the pinion 157. The rotational force generated by the rotation of the pulley 151, (155).

4 (a), when the worker pulls a force on the right side of the chain belt 153, the pulley 151 rotates in the clockwise direction and the rotational force generated at this time is transmitted to the pinion 157 through the drive shaft 155 And the reverse rotation of the pinion 157 is generated.

4 (b), when the worker pulls a force on the left side of the chain belt 153, the pulley 151 rotates in the counterclockwise direction, and the rotational force generated at this time is transmitted to the pinion 157 through the drive shaft 155, So that the forward rotation of the pinion is generated.

4 is formed of the pulley 151 and the chain belt 153, but it may be an electric motor instead of the chain belt. In this case, the electric motor further includes a control box which is physically connected to the pulley through a timing belt or the like and is capable of controlling the driving of the electric motor.

As described above, when the electric motor is used, the opening and closing of the ventilation window can be controlled completely automatically and conveniently, but the installation cost is somewhat increased compared to the chain belt system.

The first rack 161 of the present invention has a rod-shaped component extending in one direction, and has teeth formed in a straight line on one surface thereof. The teeth of the first rack 161 are fixed to the pinion 157, And the teeth are accurately meshed with the cut teeth.

Accordingly, when the pinion 157 is rotated in the reverse direction, the reverse rotation force of the pinion is converted into the linear movement force of the first rack 161, and the first rack 161 is moved in the rightward direction (a) The forward rotation of the pinion 157 is converted into the linear movement force of the first rack 161 and the first rack 161 is moved in the leftward direction b by a linear motion b).

The second rack 163 of the present invention is formed in the same shape as the first rack 161 and engages with the teeth of the pinion 157 to rotate the first rack 161 when the pinion 157 rotates forward In a direction opposite to the direction of the arrow.

More specifically, the first rack 161 and the second rack 163 are rotatable about the pinion 157 in the first rack (not shown) as shown in FIG. 4 so that the first rack 161 and the second rack 163 can linearly move in opposite directions when the pinion 157 rotates 161 are disposed on the upper side and the second rack 163 is disposed on the lower side facing each other.

The first driven rod 171 of the present invention generates an elevating operation (i.e., opening and closing operation) of the ventilation window based on the rotational force generated in association with the left (or right) linear movement of the first rack 161 .

According to the preferred embodiment of FIG. 4, the first driven rod 171 is configured to move in conjunction with the first rack 161 via the first slide bar, (The right end in the case of FIG. 4) of the first rack 161 in the longitudinal direction of the first rack 161 in the longitudinal direction.

The first driven rod 171 is formed in the shape of a bar, and one end of the first driven rod 171 is rotatably coupled to the first slide bar 165, and the other end is rotatably coupled to the ventilation window. Specifically, in the embodiment of FIG. 4, the first driven rod 171 is formed of a rectangular steel pipe, the lower end portion of the rectangular steel pipe is axially coupled to the side of the first slide bar 165 through a shaft, And the upper end was axially coupled to the left vertical frame 133 of the ventilation window through another shaft.

Accordingly, when the first rack 161 linearly moves leftward (or rightward), the first slide bar 165 connected to the first slide 161 also causes a linear movement in the leftward direction (or rightward direction). At this time, The first driven rods 171 connected to the first racks 161 and 165 move upwardly (or downwardly) the ventilation windows in conjunction with the linear movement of the first rack 161 and the first slide bar 165, Or downward rotation) to gradually open (or close) the ventilation window.

The second slide bar 167 of the present invention is a rod-shaped member connected to one end of the second rack 163 in the longitudinal direction of the second rack 163, As shown in FIG.

The second driven rod 173 is formed in the shape of a bar, one end of which is rotatably coupled to the second slide bar 167, and the other end is rotatably coupled to the ventilation window. Specifically, in the embodiment of FIG. 3, the second driven rod 173 is formed of a rectangular steel pipe, the lower end portion of the rectangular steel pipe is axially coupled to the side of the second slide bar 167 through a shaft, And the upper end was axially coupled to the right vertical frame 132 of the ventilation window through another shaft.

Accordingly, when the second rack 163 linearly moves in the left direction b (or the right direction a), the second slide bar 167 connected thereto also causes a linear movement in the leftward direction (or rightward direction) The second driven rod 173 connected to the second slide bar 167 pushes up the ventilation window in conjunction with the linear movement of the second rack 163 and the second slide bar 167 Upward rotation (or downward rotation) of the ventilation window is caused to gradually open (or close) the ventilation window.

As a result, when one pinion 157 is rotated, the two racks (i.e., the first and second racks) are moved in mutually opposite directions in association with the rotation of one pinion 157, (That is, the first and second driven rods) together operate to open or close the ventilation opening 120 by pushing up or down the ventilation opening.

The suspension device of the present invention is a mechanism for supporting the first and second slide bars and guiding the first and second slide bars to linearly move along the appropriate path, and includes a mounting hole 170, a first guide roller 511, 2 guide rollers 515, and is installed at least one, preferably a plurality of, along the longitudinal direction of the first and second slide bars.

The mounting hole 170 is a frame made of a steel material having an inner space and an inlet and an outlet for the first slide bar 165 to pass through the inner space. The mounting hole 170 of the embodiment of FIGS. And a rectangular parallelepiped member having a rectangular cross section corresponding to the first slide bar 165 having a cross-sectional shape of the first slide bar 165.

The first guide roller 511 is rotatably coupled to the inner space of the mounting hole 170 and rotates in contact with the first slide bar 165 drawn into the inner space, It serves to guide the linear motion. On the other hand, the first guide rollers 511 may be formed as one or two or more.

The mounting hole 170 is provided with an inlet and an outlet through which the second rack 163 can pass through the inner space, and is rotatably coupled to the inner space of the mounting hole 170, And a second guide roller 515 for guiding the linear movement of the second rack 163 by rotating in contact with the second rack 163.

Specifically, the first guide roller 511 is disposed on the upper side inside the mounting hole 170, and the second guide roller 515 is disposed on the lower side. The first slide bar 165 is in contact with the upper portion of the first guide roller 511 coupled to the upper side of the mounting hole 170 and the second slide bar 167 is mounted on the lower side of the mounting hole 170 The first guide roller 515 and the second guide roller 515 are in contact with each other.

On the other hand, the first guide roller 511 to the second guide roller 515 may further include covers 513 and 517, respectively. Specifically, it is preferable to further attach a cover 513 or 517 made of rubber having a high friction coefficient to the surface of the first guide roller (or the second guide roller) contacting the first slide bar (or the second slide bar) This is to ensure smooth linear movement of the first slide bar 165 by the rotation of the first guide roller 511 by increasing the adhesion of the first slide bar 165 to the first guide roller 511 .

On the other hand, the suspension device is configured to be coupled to the frame of the plastic house 100 to support the first and second slide bars. 5 and 6, the lower end of the bolt 530 is connected to the upper end of the mounting hole 170 through the tightening nut 533, and the upper end of the bolt 530 is screwed into another bolt- The suspensions are fixed to the frame of the plastic house 100 by being fastened to the brackets 520 mounted on the frame 113 of the plastic house 100 through the bolts 531.

According to another preferred embodiment, the suspension device is provided with a fixing member integrally formed with the mounting hole 170 of the suspension device in place of the bolt 530 and the tightening nut 531, and the fixing member is fixed to the frame 113 So that it can be supported and fixed to the frame of the plastic house 100 by directly fastening. In this case, there is an advantage that when the suspension device is driven to move left and right, the linear motion of the first slide bar (or the second slide bar) is prevented from being disturbed.

7 (a) and 7 (b) are diagrams showing a configuration of a vinyl house ventilation window opening / closing device and a device configuration diagram schematically illustrating a ventilation window opening and closing operation according to a modified embodiment of the present invention.

The ventilation window opening / closing apparatus shown in FIG. 7 (hereinafter, referred to as "second embodiment") is basically the same as the ventilation opening opening / closing apparatus described below and shown in FIGS. 4 to 6 And has a constitution and an operation principle. However, it is different from the first embodiment in that some constituent parts are omitted. Only the difference will be described below.

In the ventilation window opening / closing apparatus of the second embodiment, when one pinion 157 is rotated, two racks (i.e., first and second racks) are moved in mutually opposite directions in cooperation with each other, The first and second driven rods) are configured to open and close the ventilation opening 120 by pushing the ventilation opening up or down together. However, the ventilation opening opening and closing device of the first embodiment is configured to open and close the ventilation opening 120 with one rack (I.e., the first driven load).

Therefore, in the ventilation window opening / closing apparatus of the second embodiment, the second rack 163, the second slide bar 167 connected to the second rack 163, the second slide bar 167, The second driven rod 173, which is coupled as far as possible, is omitted.

The suspension device of the second embodiment also does not include the second guide roller 515 which supports the second slide bar 167 and guides the linear movement thereof.

In the case of the first embodiment, there is a disadvantage that the installation cost is increased due to an increase in the number of components in comparison with the second embodiment. However, in the case of the second embodiment, the ventilation window is pushed up or down repeatedly depending on only one rack (first rack) An external force may be exerted on only the left vertical frame 133 of the ventilation window so that the ventilation window may be bent or broken. In the first embodiment, however, the two racks share the left and right vertical frames 132 of the ventilation windows There is an advantage that the same problems as in the first embodiment can be prevented as the force is uniformly applied.

FIG. 8 and FIG. 9 are photographs showing an actual installation example of a vinyl house ventilation system having a vinyl house vent window opening / closing device according to the present invention, wherein FIG. 8 shows the ventilation closed state and FIG. 9 shows the ventilation open state.

8 and 9, in the plastic house ventilation system using the vinyl house ventilation window opening / closing apparatus of the present invention, the rotational force of the pinion 157 generated by the actuator simultaneously causes the rotational force of the first rack 161 and the second rack 163, And the linear motion force of the first and second racks is switched back to the rotational motion force of the first and second driven rods.

Specifically, when the operator pulls a force on the left side of the chain belt 153 provided on the driver in the state where the ventilation window (i.e., the ventilating opening) is closed as shown in Fig. 8, the pinion 157 is rotated forward, The first rack 161 and the first slide bar 165 move linearly in the left direction and the second rack 163 and the second slide bar 167 move linearly in the opposite direction .

As a result, the end of the first driven rod 171 connected to the first slide bar 165 performs a single-sided motion in which the trajectory of the curve is drawn in the clockwise direction, and by the force generated by the single- (That is, the left vertical frame 133) connected to one end of the vertical wall 171.

At the same time, the end of the second driven rod 173 connected to the second slide bar 167 performs a single-sided motion in which the trajectory of the curve is drawn in the counterclockwise direction. By the force generated by the single- And pushes up the ventilation window (i.e., the right vertical frame 132) connected to one end of the rod 173.

As the first driven rod and the second driven rod exert an external force on both end portions of the ventilation window, the upward rotation of the ventilation window is generated as the pushing up of the ventilation window progressively opens the ventilation window. On the other hand, the closing of the ventilation window (that is, the ventilation hole) follows the reverse order of the above-described operation.

While the preferred embodiments of the present invention have been described and illustrated above using specific terms, such terms are used only for the purpose of clarifying the invention, and it is to be understood that the embodiment It will be obvious that various changes and modifications can be made without departing from the spirit and scope of the invention. Such modified embodiments should not be understood individually from the spirit and scope of the present invention, but should be regarded as being within the scope of the claims of the present invention.
