The device can be installed in any orientation. Accordingly, the operability of the automatic water tap automatic opening / closing device can be improved in the same manner as the automatic water tap opening / closing device.
In addition, the water supplied to the light receiving surface side of the solar cell panel reaches the outer peripheral edge of the solar cell without staying on the glass plate, flows into the water channel from the water channel, passes through the drain port, and smoothly (And positively), it is discharged to the outside of the lower case, that is, to the outside of the solar cell panel housing. Therefore, the drainage of the solar cell arranged in a horizontal posture is enhanced.

In the solar cell panel housing of the present invention, it is preferable that the water passage passes through so as to gradually become narrower from the inside to the outside of the upper case in a top view.
In the said structure, the water supplied to the light-receiving surface side of a solar cell is collected more smoothly in a water flow groove.

  Furthermore, a water tap automatic opening / closing device of the present invention is a water tap automatic opening / closing device provided with the above-described solar cell panel housing, wherein the water tap driving mechanism drives the water tap of the water supply device, and the water tap driving mechanism.

Thereby, by installing the faucet automatic opening and closing device in a direction that allows easy operation of the faucet drive mechanism in the housing case and the control portion of the faucet drive mechanism, etc. The operability of the automatic tap opening / closing device can be improved.
In addition, even when water is supplied to the upper surface of the glass plate that covers the light receiving surface of the solar cell panel when it rains, the water naturally flows to the outer periphery of the solar cell panel due to the water repellency of the glass plate surface, etc. And a water flow channel formed between the outer peripheral edge of the solar battery panel and a water flow groove between the inner frame and the outer frame. The water that has flowed into the water channel is discharged from the drain outlet to the outside of the lower case. Thus, the water supplied to the upper surface of the glass plate covering the light receiving surface of the solar cell panel reaches the outer peripheral edge of the solar cell panel without staying on the glass plate, and accurately passes through the water groove in the lower case. , And smoothly and positively discharged to the outside of the lower case, that is, the outside of the solar cell panel housing. Therefore, the drainage of the solar cell panel when arranged in a horizontal posture is enhanced, and a decrease in power generation efficiency of the solar cell panel can be suppressed even after rain. Furthermore, the water flows only into the water flow groove of the lower case, does not flow into the inner frame, and the space surrounded by the inner frame of the lower case is a water stop space. Thus, wiring of the solar cell panel can be performed.

The drawings used in the following description are schematic, and the length, width, thickness ratio, and the like are not necessarily the same as the actual ones, and can be changed as appropriate.

  FIG. 1 is a front view and a cross-sectional view of a faucet automatic opening / closing device 1 of the present embodiment. FIG. 2 is a side view and a cross-sectional view of the water faucet automatic opening / closing device 1. As shown in FIGS. 1 and 2, the water faucet automatic opening / closing device 1 is attached to the upper part of the water feed device 61, and includes a water faucet drive mechanism 3, a solar cell panel 5, a housing case 7, and a solar cell panel housing. 21.

The water supply device 61 is installed in the cultivation area in order to supply water at a desired timing and amount to crops such as rice.
1 and 2 illustrate an on-off valve using a floating stop cock ball as the water supply device 61. The water supply device 61 includes a water supply pipe 63, a discharge pipe 64 having a valve opening 75, a cover 65 that covers the upper side of the discharge pipe 64, and a stopcock ball 67 that is accommodated in the water supply pipe 63 so as to be movable up and down. A spindle 69 communicated with the discharge pipe 64 in the vertical direction.

  The water supply pipe 63 is a pipe material branched from a water pipe (not shown) and led to a predetermined position in the cultivation area, and is raised substantially perpendicular to the ground. In the water supply pipe 63, the upper end portion raised from the ground and its hollow portion are expanded in diameter.

  The discharge pipe 64 has a top tube shape, is attached to the upper end portion of the water supply pipe 63, and the hollow portions of the discharge pipe 64 and the water supply pipe 63 communicate with each other. The second hollow portion of the valve opening 75 is smaller in diameter than the first hollow portion of the water supply pipe 63. The valve opening 75 is provided on the entire inner periphery of the lower end of the side wall of the discharge pipe 64 and forms a seat surface on which the outer peripheral surface of the water stopcock ball 67 can come into liquid-tight contact. At the center of the top surface of the discharge pipe 64, there is provided a spindle insertion portion that protrudes downward from the top surface and in which a through hole 73 is formed. A female screw (not shown) is formed on the inner peripheral surface of the through hole 73. The top surface of the discharge pipe 64 is provided with a plurality of discharge holes 76 that allow the second hollow portion to communicate with the outside. When the valve opening 75 is opened, water in the water supply pipe 63 flows into the discharge pipe 64 and is discharged to the outside of the water supply apparatus 61 through the discharge hole 76.

  The cover 65 is a topless member that covers the upper portion of the water supply pipe 63 of the water supply device 61. Specifically, the inside of the top surface of the cover 65 is in contact with the upper end portion (that is, the downstream end portion) of the discharge pipe 64, and the diameter is increased to form an umbrella shape from the top surface to the side wall.

  The stop cock ball 67 is a spherical member arranged on the upstream side of the valve opening 75 so as to be able to float and move up and down by the water pressure in the water supply pipe 63 in the first hollow portion of the water supply pipe 63. A plurality of guide portions 77 are provided on the inner peripheral surface of the water supply pipe 63 at intervals along the circumferential direction of the first hollow portion and projecting toward the radial center of the first hollow portion. . Guide portions 77a along the protruding tips of the plurality of guide portions 77 are formed so as to move the water stopcock ball 67 substantially coaxially along the vertical direction. Accordingly, the water stopcock ball 67 moves in the vertical direction without being shaken along the guide portions 77 a of the plurality of guide portions 77.

The diameter of the stop cock ball 67 is larger than the inner diameter of the valve opening 75 and smaller than the inner diameter of the first hollow portion of the water supply pipe 63. The stop cock ball 67 is formed of a material having buoyancy with respect to water. The buoyancy of the water stopcock ball 67 is not particularly limited, and is about 0.4, for example.
The water stopcock ball 67 does not necessarily have to be formed in a spherical shape as long as a spherical surface having a diameter larger than the diameter of the valve opening 75 is disposed on the upper side. For example, a leg portion tapered toward the lower side of the water stopcock ball 67 may be provided, or a known configuration may be provided.

  The spindle 69 is a so-called water faucet body, and is a member that is inserted into the through hole 73 from the second hollow portion of the discharge pipe 64, extends upward through the cover 65, and is connected to the water faucet drive mechanism 3. A male screw (not shown) that can be screwed into the female screw of the through hole 73 is formed on the outer peripheral surface of the spindle 69. Accordingly, the spindle 69 screwes a male screw (not shown) into the female screw of the through hole 73, and maintains the engaged state with the through hole 73 and the discharge pipe 64, while maintaining the vertical direction (that is, the water supply pipe 63 and the discharge pipe 64). In the extending direction).

A rectangular column 70 having a square cross section is inserted from above into the upper part of the shaft of the spindle 69 so as to be free in the vertical direction, and the rotational force is directly transmitted to the prism 70 from the faucet driving mechanism 3.
The spindle 69 and the prism portion 70 are preferably provided with some play in the rotational direction with respect to the faucet driving mechanism 3. As a result, a situation in which a pressure exceeding a predetermined level is applied to the spindle 69 due to an unexpected factor, or the spindle 69 is not allowed to be tilted in the axial direction, and the spindle 69 and the prism 70 are both loaded and damaged. Occurrence of excessive pulling down is prevented. Further, from the viewpoint of preventing the spindle 69 from being excessively pulled down, a stopper (not shown) may be provided on the spindle 69 protruding upward from the cover 65.

  When the water supply device 61 is closed, that is, when water is not supplied from the water supply device 61, the spindle 69 is lifted as indicated by a two-dot chain line in FIGS. Thus, the valve opening 75 of the discharge pipe 64 is in close contact with the valve opening 75 and the stop cock ball 67 is closed. When the stop cock ball 67 ascends the hollow portion of each pipe by buoyancy, the air in the hollow portion is discharged to the outside of the water supply device 61 through the valve opening 75 and the discharge hole 76 of the discharge pipe 64. Therefore, the air hammer phenomenon is prevented.

  When the water supply device 61 is opened, that is, when water is supplied from the water supply device 61, the spindle 69 is pulled down as shown by a solid line in FIGS. 69 is pushed down from the position of the valve opening 75. Thereby, the close contact state between the stop cock ball 67 and the valve opening 75 is released. Water passes through a gap (so-called throat portion) between the stop cock ball 67 and the valve opening 75, and is ejected from the discharge hole 76 of the discharge pipe 64 through the valve opening 75 and the hollow portion of the discharge pipe 64. , And discharged toward the ground along the inner surface of the cover 65 or while colliding with the inner surface.

In the present embodiment, the water faucet drive mechanism 3 is a motor made of SUS or the like, and rotates the prism portion 70 and the spindle 69 in the forward direction or the reverse direction of the arrow θ1 around the axial direction. The rotation applied to the spindle 69 is converted into a forward or reverse movement of the arrow 69 of the spindle 69 in accordance with the screwing of the male screw of the spindle 69 and the female screw of the through hole 73. In this way, the spindle 69 is pulled up or down along the vertical direction (that is, the extending direction of the water supply pipe 63 and the discharge pipe 64) by the rotation applied to the spindle 69 from the water tap driving mechanism 3.

  For example, a fitting type transmission shaft that connects the motor shaft of the water faucet drive mechanism 3 and the prism 70 may be provided. In the connecting portion of the fitting type transmission shaft, the inner size of the fitting type transmission shaft is set to be larger by about 0.2 mm in the vertical direction and the horizontal direction than the outer dimension of the prism portion 70, so that the deviation of the shaft center due to the inclination of the spindle 69 is achieved. Can be tolerated.

Further, the water that has flowed to the outer peripheral edge 5a of the solar cell panel 5 flows down from the water passage 45 to the water groove 29 as shown by an arrow R1 in FIG. The water flowing into the water flow groove 29 is discharged from the drain port 31 to the outside of the lower case 23 as indicated by an arrow R2 in FIG. At this time, by discharging water to the outside of the cover portion 38 that covers the upper end portion of the storage case 7 from the outer surface, it is possible to prevent the discharged water from flowing into the storage case 7. In this way, the water supplied to the upper surface of the glass plate 6 reaches the outer peripheral edge of the solar cell panel 5 without accumulating on the glass plate 6, and smoothly and actively through the water flow groove 29. It can be discharged to the outside of the solar cell panel casing 21. Therefore, the drainage of the solar cell panel 5 arranged in a horizontal posture can be improved. Further, the water supplied to the upper surface of the glass plate 6 flows only into the water flow groove 29 of the lower case 23, does not flow into the inner frame 25, and the inner frame 25 and the bottom plate 26 of the lower case 23, Since the space surrounded by the packing 51 and the solar cell panel 5 is a water stop space, wiring of solar cells and the like can be performed in this space.

  Further, according to the automatic faucet opening and closing device 1 of the present embodiment, since the opening area of the drain port 31 is larger than the opening area of the water passage 45 of the upper case 41, water accumulates inside the solar cell panel casing 21. Can be prevented. Therefore, water can be discharged more quickly to the outside of the solar cell panel casing 21, and the drainage of the solar cell panel 5 can be further improved.

  Moreover, according to the water faucet automatic opening / closing device 1 of the present embodiment, the solar cell panel housing 21 is detachably provided in the housing case 7, and therefore when the solar cell panel 5 is inspected and replaced, Alternatively, when cleaning the upper case 41 and the lower case 23, etc., the solar cell panel housing 21 can be temporarily removed from the housing case 7, and after the work has been performed, it can be attached to the housing case 7 again. That is, maintenance of the solar cell panel 5 and the solar cell panel housing 21 can be easily performed.

Furthermore, according to the solar cell panel casing 21 of the present embodiment, since the light receiving surface 5p of the solar cell panel 5 is disposed horizontally as described above, it is substantially constant regardless of the installation direction of the water faucet automatic opening / closing device 1. The power generation efficiency can be obtained. Therefore, the water faucet automatic opening / closing device 1 can be installed in an arbitrary direction. Therefore, the operability of the water faucet automatic opening / closing device 1 can be improved.
Further, the water supplied on the light receiving surface 5p of the solar cell panel 5 reaches the outer peripheral edge 5a of the solar cell panel 5 without accumulating in the window W of the upper case 41, and from the water channel 45 to the water channel 29. It can be made to flow in, and can be discharged | emitted out of the solar cell panel housing | casing 21 smoothly and rapidly through the drain outlet 31. FIG. Therefore, the drainage of the solar cell panel 5 arranged in a horizontal posture can be improved.

  The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific embodiments, and various modifications are possible within the scope of the gist of the present invention described in the claims. Deformation / change is possible.

  For example, when the opening area of the drain port 31 is close to the opening area of the water passage 45 or when the faucet device 61 has almost no inclination, the bottom plate 26 of the lower case 23 is placed in the horizontal direction as shown in FIG. The outer frame 27 that is inclined with respect to D4 and is positioned below may be cut out. In such a case, the water that has flowed into the water flow groove 29 flows down from the upper side along the slope, is discharged from the drain port 31 to the outside of the lower case 23, and at the downstream end that has flowed down, the outer frame 27 is also discharged to the outside of the lower case 23 from the notch 33. Therefore, the water flowing into the water flow groove 29 can be discharged to the outside of the solar cell panel casing 21 more quickly, and the drainage of the solar cell panel 5 can be improved.

  Further, for example, various sensors may be electrically or physically connected to the control unit 15 housed in the housing case 7. If the control unit 15 is electrically connected to a water level sensor installed in the cultivation area, the amount of water supplied and the timing of water supply by the automatic faucet automatic opening / closing device 1 can be controlled more accurately. In addition, if a supply device for fertilizers, pesticides, etc. is connected to the control unit 15, these fertilizers, pesticides, etc. are reliably supplied to the cultivation area at the same time as or before and after the water supply by the automatic faucet automatic opening / closing device 1. You can also

For example, in the said embodiment, although the water supply apparatus 61 using the floating stop cock ball | bowl 67 was illustrated and demonstrated as an object which attaches the water tap automatic opening / closing apparatus 1, the water supply apparatus 61 is made into a floating type thing. It is not limited, For example, the gate-type water supply apparatus which opens and closes a water channel by raising / lowering of a plate-shaped member may be sufficient, and the water supply apparatus provided with the other structure may be sufficient. What is necessary is just to change suitably the shape of the water tap drive mechanism 3 of the water tap automatic opening / closing apparatus 1 according to the shape of the water tap (if it is a gate type water supply device) of the water supply device 61.
