Description

  The present invention relates to a temperature sensor light-shielding device that prevents a temperature sensor that detects room temperature in a greenhouse such as a greenhouse from receiving direct sunlight, and a molding method thereof.

  Generally, in greenhouses such as greenhouses for growing plants and glass houses, it is generally necessary to keep a room temperature suitable for growing plants constant.

  For this reason, in conventional greenhouses, a ventilation device is provided on the roof, side wall, etc. of the house, and when the room temperature becomes higher than the standard temperature, the ventilation device is opened to introduce outside air, and when the temperature becomes low, the ventilation device is closed. Is normal.

  As such a ventilation device, for example, as shown in Patent Document 1 (JP 2013-34443A), Patent Document 2 (JP 2002-305990A), and Patent Document 3 (JP 2001-120081A). Have been developed and are being implemented.

  For example, the ventilator disclosed in Patent Document 1 has an opening / closing sheet that opens and closes an opening formed in a side wall of a house, a winding shaft that winds the opening / closing sheet and rewinds it, a drive machine that rotates the winding shaft, and this drive machine. And a guide column that guides along the axial direction.

  Further, the drive machine has a drive machine main body and an electric motor which can be operated by a control panel built therein, and the control panel is connected to a temperature sensor arranged in the house through a signal line.

  When the temperature sensor detects that the temperature inside the house has risen above a specified temperature, the electric motor is driven by the control panel to rotate the winding shaft and wind the open / close sheet to open the opening by a predetermined amount. Let go.

  On the other hand, when the temperature detects that the room temperature in the house is lower than the set value, the electric motor is driven in the opposite direction to wind the open / close sheet while rotating the winding shaft in the winding direction, and the opening is closed. I am trying.

  On the other hand, when the above temperature sensor is hung at a predetermined position in the house, direct sunlight from the sun directly irradiates the temperature sensor through the transparent roof side and side transparent sheets or transparent glass. In this case, the temperature sensor is heated, and it becomes impossible to detect the room temperature as set, and as a result, the ventilation system cannot be kept open and the room temperature cannot be maintained as set, which may hinder plant growth. .

  Therefore, conventionally, for example, a light shielding device for a temperature sensor as shown in FIG. 13 has been developed.

  That is, as shown in FIGS. 13 (A), 13 (B) and 13 (C), the temperature sensor shading device includes a temperature sensor Q and a conical umbrella main body 101 made of metal inserted and attached to the outside of the temperature sensor Q. And a mounting member 104 that connects the temperature sensor Q and the umbrella body 101.

    The mounting member 104 includes a cylindrical body 102 that connects the base end of the temperature sensor Q and the signal line R, a flange Q1 that is integrally provided on the base end side of the temperature sensor Q, and a nut 103 screwed to a screw 103 on the temperature sensor side. The upper end side horizontal portion of the umbrella body 101 is sandwiched between the flange Q1 and the nut 103.

  According to this temperature sensor shading device, since the umbrella body 101 is arranged outside the temperature sensor Q so as to cover the temperature sensor Q, direct sunlight is prevented from being directly applied to the temperature sensor Q and is heated. Never.

  Therefore, the temperature sensor Q can properly detect the room temperature in the greenhouse, and the ventilation by the ventilation device cannot be performed accurately.

Patent Document 1 (see JP 2013-34443 A, FIG. 1, paragraphs 0020 and 0032)
Patent Document 2 (see JP 2002-305990 A, FIG. 4, paragraph 0016)
Patent Document 3 (see JP 2001-120081 A, FIG. 8, paragraph 0030)

  However, the conventional shading device for the temperature sensor shown in FIGS. 13A, 13B, and 13C has the following problems to be improved.

  First, the umbrella body 101 and the temperature sensor Q are composed of a cylindrical body 102, a flange Q integrally provided on the base end side of the temperature sensor Q, and a nut 103 screwed into a screw 103 on the temperature sensor side. Since the attachment member 104 is connected by the attachment member 104, the attachment member 104 needs to be molded separately from the umbrella main body 101, the structure is complicated and the number of parts is large. It is disadvantageous in terms of assembly operability and economy.

  Secondly, since the umbrella body 101 is made of metal, it is easily heated when exposed to direct sunlight, and this heat may be dissipated by the temperature sensor Q and impair the detection function of the temperature sensor Q.

  Thirdly, the umbrella body 1 is shaped like a frustoconical body, and since this material is metal, it is heavy and cannot be folded compactly, so when storing a large number in a warehouse or from a manufacturing site to a usage site. The carrying operation is bulky and requires a large storage space for storage and a large box for carrying, which makes storage and carrying work difficult.

  Therefore, an object of the present invention is to reduce the number of parts, the structure is simple, the weight is light, and the storage space and the transportation box can be made compact when storing or transporting, and the workability and workability are improved. It is an object of the present invention to provide a shading device for a temperature sensor and a molding method.

  A light shielding device for a temperature sensor and a molding method thereof according to an embodiment of the present invention will be described below with reference to FIGS. 1 to 128.

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temperature sensor light-shielding device that prevents a temperature sensor that detects room temperature in a greenhouse such as a greenhouse from receiving direct sunlight, and a molding method thereof.

  As is well known, the temperature sensor is installed in a greenhouse such as a greenhouse or a glass house, and detects the temperature inside the house and sends a detection signal to a control panel on the ventilation device side through a signal line. There is.

  Then, when it is detected that the temperature inside the house becomes higher than a predetermined temperature, the electric motor is driven by the control panel, and for example, the winding shaft as a ventilation device is rotated while being wound around the winding shaft. The opening / closing sheet is rolled up to release a predetermined amount of the opening formed on the roof or the side surface of the house.

  On the other hand, when the temperature sensor detects that the room temperature in the house is lower than the set value, the electric motor is driven in the reverse direction to wind the open / close sheet while rotating the winding shaft in the winding direction to open the opening. I try to close it.

  In this case, direct sunlight from the sun may pass through the transparent transparent sheet or transparent glass on the side of the roof or the transparent glass and may be directly applied to the temperature sensor.In this case, the temperature sensor is heated and the room temperature as set is set. Can not be detected, and as a result, the room temperature cannot be maintained as set by keeping the ventilator open, which may hinder plant growth.

  The present invention is characterized by a temperature sensor light-shielding device that prevents the temperature sensor from being exposed to direct sunlight and a method of forming the same.

  A shading device for a temperature sensor according to an embodiment of the present invention is shown in FIG.

  The light-shielding device P of the temperature sensor is to shield the temperature sensor Q from direct sunlight with an umbrella P arranged outside the temperature sensor Q connected to the tip of the signal line R.

  The umbrella P is a truncated cone-shaped umbrella body 1 that is detachably engaged with engaging portions K formed by opposing ends of a semicircular sheet made of paper or synthetic resin, and the umbrella body 1 2, an opening 2 formed at the upper end of the opening 2, a support piece 3 standing upright from the vicinity of the rim of the opening 2 above the umbrella body 1, and two or more holes formed in the support piece 3, for example, It has three holes A1, A2, and A3.

  The temperature sensor Q is suspended from the opening 2 in the umbrella body 1 while the signal line R is alternately passed through the holes A1, A2, A3 and the signal line R is held by the support piece 3.

  Therefore, since the umbrella main body 1 is arranged on the outer peripheral side of the temperature sensor Q, direct sunlight passing through the transparent sheet of the vinyl house or the transparent glass of the glass house is blocked by the umbrella main body 1 and directly radiated to the temperature sensor Q. Therefore, the temperature sensor Q is not heated by solar heat and can properly detect the room temperature in the greenhouse.

  The umbrella body 1 is preformed with a white sheet, or the outer periphery of the umbrella body 1 is coated with white color to prevent the umbrella body 1 from being heated by the sun rays and to prevent the heat from being transmitted from the umbrella body 1 to the temperature sensor Q. You may keep it.

  In addition, the tongue piece 5 formed by the U-shaped or U-shaped notch 4 is cut and raised on the body portion of the umbrella body 1 to form the vent hole 6 to ventilate the inside of the umbrella body 1. It is possible to prevent the temperature inside the umbrella body 1 from rising.

  According to the temperature sensor light-shielding device of FIG. 1, since the support piece 3 that stands upright above the umbrella body 1 is provided, the umbrella body 1 can be attached to the temperature sensor Q and the signal line R using this support piece 3. Therefore, as compared with the conventional light shielding device of the temperature sensor which is a separate member, a mounting tool is unnecessary, the number of parts is small, the structure is simple, and the workability, the assembling property, and the economical efficiency are improved.

  Further, since the umbrella body 1 is formed of a sheet made of paper or a synthetic resin, it is lightweight, and is less heated than the metallic umbrella when it is exposed to direct sunlight, and the temperature sensor Q detects it. It is possible to prevent deterioration of the function.

  Further, since the umbrella P is detachably coupled to the both ends by the engaging portions K formed to face each other, the umbrella main body 1 is seated before or after the engaging portions K are coupled. Since the base material is shaped like a base, a large number of the umbrellas P can be stacked compactly in the base material state. As a result, even in a small storage space, a large number of umbrellas P can be stored in the state of the base material, and even when transported from the manufacturing site to the greenhouse, which is the site of use, a box with a small storage space can be used and stored. The transport work can be improved.

  Although the umbrella P1 in FIG. 1 has a frustoconical shape, the umbrella P may be formed in a rectangular shape or a trapezoidal shape when viewed from the side. The point is that the opening 2 is provided in the upper part, and the support piece 3 is integrally provided in the vicinity of the edge of the opening 2 so as to be molded, and the ends of the sheet are detachably coupled by the engaging portion. If there is, it can be implemented.

  The support piece 3 may be integrally molded on the inner circumference or the outer circumference of the opening 2 near the rim, or may be attached and placed.

  The engaging portion K is formed by engaging V-shaped grooves formed at mutually opposite ends of a semicircular or rectangular sheet, one groove and a claw that is detachably engaged with this groove, or one of the grooves. It is possible to employ a structure in which the hole and the other protrusion that is detachably fitted into the hole and hooked therein, or that is detachably sewn with a thread or the like.

  The point is that the engagement portion K is only required to be able to form the umbrella P into a simple flat sheet-shaped base material before or after the engagement is released.

  An embodiment of a sheet-shaped base material used for the umbrella P of FIG. 1 is shown in FIG.
