Description

  The present invention reduces the volume of a house such as a greenhouse, secures the amount of outside air and / or inside air required for the house and / or the amount of exhaust air, and blows outside air to an optimum place in the house and The present invention relates to a double curtain open / close ventilation device that covers the inside of an outer curtain of a house that exhausts air inside the house to the outside of the house.

  Recently, cultivation of crops such as vegetables, leaf vegetables, fruits, flowers, etc. with no pesticides or reduced pesticides (pesticide-free or reduced pesticides) has become mainstream. The reason for this is natural, and this kind of pesticide-free cultivation is useful for people's health and effective in the recovery and / or prevention of disease, or when considering the maintenance of agriculture in Japan, It can be considered to be a form or indispensable when considering the maintenance of the global environment, which is a permanent theme of humankind.

  As mentioned above, greenhouse cultivation such as greenhouses has come in handy for the purpose of cultivating crops or raising livestock and harvesting them throughout the year without being affected by the weather and weather conditions. It was. These houses are crops that grow in house cultivation because there is no ventilation or circulation of outside air and / or inside air in the house unless ventilation fans and circulation fans are installed on the ceiling and wife surfaces. Or pigs, cattle, chickens, etc. raised in barns are susceptible to diseases, and improvement of their growth environment has been demanded.

  In addition, depending on the type of crop, the temperature difference between day and night, the deviation between temperature and humidity may cause condensation of the crop, resulting in leaf leaf disease, plague, etc., resulting in a decrease in yield and the inability to harvest good quality crops. In addition, there is a problem in that pests are generated in this crop and the crop is eaten by the pests, so that the efficiency of house cultivation cannot be improved.

  Therefore, as means for solving such problems, various ideas have been disclosed in order to improve the efficiency of house cultivation as in the present invention, and will be exemplified below.

  First, as a prior document cited first (referred to as Document 1), there is a “ventilator for double-tensioned house” disclosed in Japanese Utility Model Laid-Open No. 05-47739. This outline shows that a string is passed through the top end of each vinyl in the internal house, a space is provided in the ceiling, and the ceiling part of the internal house is attached to the ceiling straight pipe pipe of the external house so that it can be raised and lowered. It is intended to be a double-tensioned house ventilation device that has a low-cost equipment, reduces operation time and labor, and significantly increases the ventilation effect.

  Next, as a prior document cited secondly (referred to as Document 2), there is a utility model registration No. 3081396 “Ventilation sheet winding device for agricultural greenhouse”. This outline is a ventilation device for agricultural greenhouses, with a connecting part that connects to the winding pipe arranged at the lower end of the house seat at the base end and a rotating shaft that is free to rotate adjacent to the connecting part And a rotation portion having a square cross section for stopping the rotation of the rotation shaft, and a rotation handle disposed on the other end side of the rotation shaft portion, and the lock portion of the shaft rotation portion. The frame is slidable to the left and right, and has a rectangular cross section that can stop rotation when tightly fitted, a guide tube that is slidable up and down, and a part of this guide tube with a rotating part Winding seats for ventilation in agricultural greenhouses with a relatively simple mechanism that allows the seats to be rolled up with a handle with a relatively simple mechanism. apparatus It intended to provide.

  Finally, as a third prior art document (referred to as Document 3), there is a “double film-covered building” of JP-A-2005-269963. In this outline, at least a part of the roof or the wall is covered with a double film, air is blown into the gap between the double films by a blower to form an air layer, and an exhaust hole communicating with the air layer is provided, A valve element that opens when the pressure in the air layer exceeds a predetermined value is installed in this exhaust hole, reducing the stress applied to the film when a strong wind blows, etc. It is intended to provide a double film-covered building that can be prevented.

Japanese Utility Model 05-47739 Utility model registration No.3081396 JP 2005-269963 A

  Document (1) can use an existing double-tensioned house, and by opening the inside, the outside air is sucked into the house from the ceiling surface and / or the inside air is discharged outside the house. Although it is a configuration, if the site area in the house is large, this ventilation will not be stable, and the distribution of ventilation to the crop will occur, and the amount of outside air required for the house and / or the amount of exhaust will be secured In addition, the outside air that has been sucked in is blown to the optimum place in the house and / or the air in the house is exhausted to the outside of the house. It is considered that it is impossible to ensure the environment and to optimize the temperature / humidity management and / or to replace the air to secure the growth environment of the crop and to expand the yield. Moreover, the work of opening and closing the ceiling surface becomes complicated, and there are problems that are undesirable for the workers and users of the house.

  Next, the document (2) is a configuration in which a part of the house is rolled up, and outside air is sucked into and / or discharged from the house from the rolled-up open portion. Similarly, it seems to have various problems.

  Finally, the document (3) has a structure in which an exhaust hole is formed in the double film and the valve body opens when a predetermined pressure is exceeded, but when the double film is replaced, the exhaust hole is provided. Since the exhaust pipe is used, air is exhausted only from the hole corresponding to the diameter of the exhaust pipe, and it takes time to perform exhaust, which is considered troublesome in the case of changing the tension. And this seems to be the same for the incorporation. And these problems are because the operating time of the blower is lengthened, and accordingly, the operating equipment becomes longer, the fuel is used more, and it takes time to replace the double film. It is thought that it is impossible to optimize crops and / or replace air, to secure a growing environment for crops, and to expand yields.

Therefore, the present invention has the following effects in order to solve the above problems.
(B) By covering the inside of the outer curtain of the house with a double curtain, the volume of the house is reduced, the amount of outside air necessary for the house and / or the amount of exhaust is secured, and this is taken in. To blow the outside air to the optimum place in the house and / or exhaust the air in the house to the outside of the house, avoid direct blowing to the crop and overdrying, and ensure leaf respiration, and In addition, it is possible to optimize temperature and humidity management and / or replace air, to secure a growing environment for crops and to expand the yield.
(B) Further, by covering the double curtain, it is possible to prepare a growing environment such as improvement of heat retention and air permeability, to provide high quality crops, and to expand the yield.
(C) No one hassle in opening and closing the double curtain, it can be performed smoothly and efficiently, and the time can be shortened. The cost of operating the blower as this time is shortened , Reducing the burden on the manager of the house, and ensuring convenience.
(D) Diversification of the ventilation of the house that supports this double curtain and efficient ventilation, or ensuring convenience, insect prevention and prevention of beneficial insect invasion, efficiency of house cultivation, pesticide-free, etc. It is possible to contribute to.

(1) Explanation of house.
FIG. 1 shows a house such as a vinyl house or an agricultural house, a dome shape, a semicircular shape, a triangular shape or the like ceiling, a ceiling surface 1a that is a roof, and a wife surface that is on the short side a (width direction). 1b and the side surface 1c on the longitudinal direction B are assembled. And although not shown in figure, the entrance / exit for an operator to enter / exit is provided in at least one of this wife surface 1b.

  The house 1 has a structure in which a ventilation fan 2 having an opening / closing mechanism such as a shutter is installed on the wife surface 1b. In this ventilation fan 2, the ventilation fan 20 provided on one wife face 1b is used for intake, and the ventilation fan 21 provided on the other wife face 1b is used for exhaust. By using both the intake air and the exhaust air, the outside air can be sucked into the house 1 and the outside air can be discharged to the outside of the house 1, the outside air can be stably blown, and a reliable and stable growing environment condition for the crop can be achieved. Can be arranged. Note that the ventilation fans 20 and 21 are provided with a rotation mechanism (not shown) so that the ventilation can be adjusted.

  Further, in the house 1, there is a circulation fan 4 suspended in the longitudinal direction B by a plurality of appropriate intervals from the ceiling surface 1a. The circulation fan 4 is provided with a depression angle adjusting function and a rotating function, and can accurately capture the flow of the outside air and / or the inside air in the house 1 to ensure the air flow in the longitudinal direction.

(2) Description of a double curtain with two sheets.
An outer curtain 7 is stretched on the ceiling surface 1a of the house 1, and the shape of the outer curtain 7 is a substantially phase shape corresponding to the shape of the ceiling surface 1a. Then, a curtain is stretched so as to be substantially parallel to the ceiling surface 1a from the substantially central portion of the wife surface 1b of the house 1 to the outside. In addition, this curtain becomes a double structure by interposing the wire member 8 and turning back at a substantially central portion in the longitudinal direction, whereby a double curtain 9 is formed.

  The double curtain 9 is supported by a wire member 8 laid on the longitudinal direction B from one end surface 1b to the other end surface 1b. The wire member 8 is not limited as long as its shape, material, etc. are not required, and the double curtain 9 can be properly tensioned. And this wire member 8 shall be movable, and when fixing the wire member 8, although not shown in figure, a locking member etc. should just be provided in the beam etc. of the house 1, and should just be detachable.

  The double curtain 9 is bent with the wire member 8 interposed therebetween. For example, one end of the bent curtain 9 is set as a bent end portion 9b, and the other end thereof is set as an open end portion 9a. A rotating bar 11 is attached to the open end 9a. The rotating bar 11 is provided with a certain distance in order to press-contact or open the open end 9a of the double curtain, but is preferably provided in the vicinity thereof, and further, the press-contact from the state where the double curtain 9 is suspended. Or in order to open, it provides in the hanging part of the double curtain 9. FIG.

  The wire member 8 is installed in the longitudinal direction B with an appropriate interval between the open end 9a and the bent end 9b of the double curtain 9. This wire member 8 should just be the tension | tensile_strength state of the double curtain 9, for example, exists every 3 m. And in order to hold | maintain this tension | tensile_strength, the double curtain 9 is fixed by the fixing means 12, and the double curtain 9's reluctance, rattle, and deviation are suppressed. For example, the fixing means 12 can be attached to the rotating bar 11 at the upper part of the open end 9a.

(3) Explanation of driving means.
The driving means 15 is an electric means that controls the forward or reverse rotation of the rotating bar 11, smoothly rotates the rotating bar 11, and is provided with a manual mechanism by an operator or an administrator or a control mechanism such as a solenoid or an actuator. Conceivable. It is desirable that the driving means 15 can be switched between manual means and electric means so that it can quickly respond to an emergency such as a power failure or disaster. In addition, the double curtain can be opened and closed simply by rotating the rotating bar 11, and the amount of air can be adjusted. Costs can also be reduced.

(4) Description of attachment procedure.
Since the general configuration has been described above, an installation procedure for actually stretching the double curtain 9 will be described below with reference to FIGS. 3-1 to 3-5.

  First, as shown in FIG. 3A, the double curtain 9 is bent at the bent end portion 9b, the open end portion 9a is opened, and the rotating bar 11 is provided below the open end portion 9a. . A wire member 8 is provided between the open end 9a and the bent end 9b. These wire members 8 play a role of transmitting this rotation to the double curtain 9 when, for example, the rotating bar 11 rotates in the forward or reverse direction.

  Then, as shown in FIG. 3-2, when the rotating bar 11 is rotated forward clockwise, the open end 9 a is pressed and the double curtain 9 is wound together with the fixing means 12. And by this forward rotation, the open end portion 9a to the bent end portion 9b are in a sealed state, and an air layer is interposed therein.

In FIG. 3C, outside air and / or inside air is taken in by the blower 16, until the amount of the air layer is saturated (filled) by visual observation or a sensor (not shown) by the operator.
Air is taken in. The amount of the air layer is desirably determined in consideration of various growth conditions such as weather, temperature, and humidity. And when this air amount is put in too much, it adjusts by releasing the air mentioned later.

  FIG. 3-4 illustrates the release of the outside air and / or the inside air. When the rotating bar 11 is reversed, the open end 1a is released from the rotating bar 11 and becomes free. Release is performed. However, with this procedure alone, the speed of releasing the outside air and / or inside air is slow, and as shown in FIG. 3-5, by pushing the bent end portion 9b toward the open end portion 9a, the outside air And / or the inside air can be released smoothly and the time can be shortened. With this shortening, the cost for operating the blower can be reduced, and the burden on the manager of the house can be reduced. It can be considered to contribute to securing.

(5) Description of a four-layer double curtain.
As shown in FIG. 4, when the house 1 is long in the short direction a, the double curtain 9 may be stretched by four sheets. Basically, as described above, (2) the configuration is the same as that described in the description of the two-layered curtain, and only the differences will be described, but outside air and / or inside air is taken into the double curtain 9. It is also possible to connect the blower 16 with a cheese tube 17 or an elbow tube (not shown) or to install the blower 16 individually on the double curtain.

(6) The other configuration will be described.
Although not shown, a sensor such as a temperature / humidity sensor, a rain sensor, a wind sensor, or a snow sensor is provided in the house 1, and the driving means 15 can open / close the double curtain 9 or take in or release air. is there. In addition, timer control can be considered.
