Description

  The present invention relates to a power supply unit that applies a predetermined voltage to an electric fence at a desired time.

  The electric fence is used as a means for preventing the invasion of beasts, such as those provided around farms, leisure facilities, etc., or as a means for preventing livestock bred on the ranch from escaping outside the ranch. In this electric fence, a plurality of poles are provided at predetermined intervals around the land to be protected, and a protective wire such as a bare electric wire or a conductive wire mesh is stretched between the poles to constitute the fence. Then, when an electric current is passed through the stretched protection line, an animal that touches the protection line in an attempt to enter the land is electrocuted and repulsed. Beasts that have been touched by electric fences can no longer approach because of fear of the fence. The technique of such an electric fence is well-known (refer patent documents 1-4).

  In order to apply a high voltage to the protective wire, a power supply unit is connected to one end of the protective wire. The power supply unit includes an output terminal and a ground terminal. The output terminal is connected to the protective wire via a cord, the ground terminal is connected to the earth rod via the cord, and the earth rod is grounded. By generating a pulse voltage from the power supply unit, a voltage of about 10,000 volts is applied to the protective line with respect to the ground. When a beast comes in contact with this protective line, an electric current flows between the protective line and the ground through the body of the beast, so the beast feels a strong impact and does not try to approach it.

In order to prevent nocturnal beast from entering the farm, a light sensor is connected to the control circuit. Also known is a technique in which generation of a voltage is stopped after a predetermined time has elapsed when the brightness becomes brighter than a set brightness from a dark state. (See Patent Document 5).

  As shown in FIGS. 7 and 8, the power supply housing 3 is configured in a box shape with the top open, and the shape of the upper outer periphery is configured to match the bottom shape of the operation unit housing 2. The operation unit housing 2 is placed and fitted on the body 3 so as to be fixed. That is, the connecting means 7 is arranged on both side surfaces of the power supply housing 3 and both side surfaces of the operation unit housing 2 so that it can be released and fixed with one touch.

  As shown in FIGS. 1, 2, and 5 (a), the connecting means 7 includes rotating members 71 and 71 pivotally supported on the left and right side surfaces of the operation unit housing 2 and the power supply housing 3. It is comprised by the fixing members 72 * 72 fixedly provided in the center of the upper end part on both right and left side surfaces. The rotating members 71 and 71 are pivotally supported by rotating member mounting portions 71a and 71a provided at the center of the lower end portions on the left and right side surfaces of the operation unit housing 2.

  Here, with reference to FIG. 5, the structure of the connection means 7 and the mechanism of connection are further explained in full detail. The rotation member 71 is provided with a rotation shaft portion 74 at the upper end portion of the body portion 73, and the rotation shaft portion 74 is provided with a shaft hole 74a in the front-rear direction as shown in FIG. It has been. On the other hand, the rotation member attaching portion 71a of the operation unit housing 2 is provided with shaft holes 74b and 74b in the front-rear direction, and the shaft hole 74a is sandwiched between the shaft holes 74b and 74b, and then the shaft hole. A shaft rod 74c is inserted into the shaft 74a and the shaft holes 74b and 74b. Thereby, the rotation member 71 can be freely rotated about the shaft hole 74a as a central axis.

  A protruding portion 75 protrudes from the middle portion of the trunk portion 73 on the housing side, and the protruding portion 75 is formed as a convex portion having a circular shape when viewed from the front. The body part below the projecting part 75 is a knob part 76.

  On the other hand, in the fixing member 72, a fixing plate 78 and a locking portion 77 are integrally provided on the side wall of the power supply housing 3, and the locking portion 77 is L-shaped in cross-section (reverse L-shaped in the drawing). And formed integrally with the fixing plate 78. The upper end surface of the locking portion 77 is in contact with the bottom surface of the rotating member mounting portion 71a of the operation unit housing 2, and the lower end portion of the locking portion 77 protrudes outward and downward to form a locking piece 77a. The recess 77 b is provided at the lower portion between the locking piece 77 a and the fixing plate 78.

  With the above configuration, after the bottom portion of the operation unit housing 2 is fitted to the stepped fitting portion provided at the upper end portion of the power supply housing 3, the rotating members 71 and 71 in the connecting device are connected to the connecting device. Both housings are connected and fixed by being locked to the fixing members 72.

  That is, when the operation unit casing 2 is fitted on the power supply casing 3 and the rotating member 71 is rotated downward to push the knob portion 76 toward the side wall of the power supply casing 3, FIG. As shown in (d), the protrusion 75 gets over the locking piece 77a of the locking portion 77 and fits into the recess 77b, and the operation portion housing 2 and the power supply housing 3 are connected and fixed easily. It will be in a state that cannot be removed.

  When the rotating member 71 is removed from the fixed member 72, as shown in FIG. 5E, by pulling the knob portion 76 outward from the inside, the body portion 73 is bent and the projection portion 75 is pushed downward. The projecting portion 75 can easily get over from the locking piece 77a, and the rotating portion 71 is detached from the fixed portion 72.

  As described above, the connecting means 7 is easy to operate, has a small operating force, and can realize a strong connected state after the connection is fixed. In addition, the rotation members 71 and 71 and the fixing portions 72 and 72 of the connecting means 7 may be configured to be provided in the power supply housing 3 and the operation unit housing 2, respectively, contrary to the present embodiment.

  Further, the power supply housing 3 is formed in a substantially U shape in a sectional view, and as shown in FIGS. 7 and 8, a box-shaped storage portion 91 having an upper portion opened in a U shape in a sectional view is further provided at the center of the bottom portion. Is formed. The storage unit 91 is configured to have a size that can store a dry battery in a state of being connected in series, and can store a dedicated charging battery. In this way, the power supply is stored so that the power supply does not rattle.

  In addition, a space between the storage portion 91 and the inner surface of the power supply housing 3 can be configured to store a spare battery 92. By effectively using the space, unexpected battery exhaustion or battery It is designed to respond promptly to rising.

  In addition, a wiring insertion hole 10 for connecting to an external power source is opened at the bottom of the housing portion 91 of the power supply housing 3, and an electric wire is passed through the insertion hole 10 through the insertion hole 10. I try to make it. The insertion hole 10 is closed with a lid when a battery or a battery is in use to prevent intrusion of water or the like. However, the hole 10 may be configured to be provided on the side surface of the housing, and the position is not particularly limited.

  When the insertion hole 10 is used, an external power source is used, and a power supply wire is inserted to supply power from an external power source such as a household AC power source, a solar panel, or an external battery. use. When power is supplied from an AC power source, an AC-DC converter (adapter) is connected to an outlet, and a power supply line is drawn through the insertion hole 10 into the power supply housing 3 and connected to the power line connection terminal 8. In addition, when a battery is attached to the storage portion 91 and the battery is charged, the power supply line is similarly passed through the insertion hole 10 and connected to the battery.

  Further, as shown in FIG. 3, the solar panel 12 can be attached to the upper edge (grip) of the operation unit housing 2. That is, a hook-shaped fixing portion (not shown) is formed on the back surface of the solar panel 12 so that the solar panel 12 can be easily fixed to the operation unit casing 2. Then, the electric power generated by the solar panel 12 is charged into a battery mounted in the storage unit 91 of the power supply housing 3 via a feeder line. The feed line is connected through the insertion hole 10 as described above.

  As described above, in the power supply unit 1 according to the present embodiment, the power supply can be selected according to the installation environment. In other words, if the place where the power supply unit 1 is installed is close to the place where houses, utility poles, etc. are installed and power can be supplied from an outlet, the battery can be replaced by supplying power using an AC-DC converter. Maintenance such as is unnecessary. In addition, when there is no outlet nearby and there is nothing that blocks the sun, maintenance such as battery replacement becomes unnecessary by using the solar panel 12 and the battery. And if there is no outlet nearby and there are obstacles that block the sun, batteries are used.

  Thus, the power supply unit according to the present invention can be used universally as means for supplying power to a general electric fence.

  Next, the electric circuit will be described with reference to FIG.

  The control circuit 30 is housed in the operation unit housing 2, and power is supplied from the power supply in the power supply housing 3 via the switch 41 and the connection terminals 20 and 21. Connected to the control circuit 30 are the optical sensor 11, the continuous operation switch 42, the day operation switch 43, the night operation switch 44, the test switch 45, the power lamp 46, the voltage OK lamp 47, the voltage shortage lamp 48, the booster circuit 50 and the like. The control circuit 30 includes a CPU, a RAM, a ROM, an input / output port, a voltage checker, a relay, and the like.

  Continuous operation connected to the power switch 41, continuous operation switch 42, day operation switch 43, night operation switch 44, test switch 45, power lamp 46, voltage OK lamp 47, voltage shortage lamp 48, and continuous operation switch 42. The switch operation unit 4 includes a lamp 42 a, a day operation lamp 43 a connected to the day operation switch 43, and a night operation lamp 44 a connected to the night operation switch 44.

  When the power switch 41 is turned on, the power lamp 46 is turned on. When the test switch 45 is pressed in this state, a voltage checker is connected. If the voltage is higher than the set voltage, the voltage OK lamp 47 is turned on. If the voltage is lower than the set voltage, the undervoltage lamp 48 is turned on. When the power lamp 46 is not lit, it is a disconnection, battery exhaustion, or battery exhaustion.

  In order to prevent the invasion of beasts, it is possible to switch between a daytime operation mode in which power is supplied only during the day, a night operation mode in which power is supplied only at night, and a continuous operation mode in which power is always supplied. The operating state of the electric fence can be changed by selecting and operating the continuous operation switch 42, the day operation switch 43, and the night operation switch 44). In other words, when using an electric fence, the behavioral characteristics vary depending on the type of beast. For example, when only nocturnal beasts are mainly targeted for prevention, it may be energized only at night, and conversely, if diurnal beasts are targeted, it may be energized only during the daytime. Therefore, useless power consumption can be suppressed by selecting the operation mode. In the conventional power supply unit, when switching the operation mode with the power turned on, the operation mode switch must be selected after the power is turned off once and turned on again. In other words, the operation mode could not be switched while the power was on. For this reason, it takes time and effort to operate the power switch, and even if the power switch is turned on, it does not change even if the operation mode switch is pressed.

  Therefore, in the power supply unit according to the present invention, the operation mode can be switched only by operating the operation mode switch while the power is on.

  In the continuous operation mode, when the continuous operation switch 42 is pressed ON, the continuous operation lamp 42a is turned on, and the input voltage to the control circuit 30 is boosted to a predetermined voltage (about 10,000 volts) by the booster circuit 50. The voltage is applied to the protective wire 120 from the output terminal 5 via the cord. The ground terminal 6 is connected to the ground bar 130 through a cord and grounded.

  In the daytime operation mode, the daytime operation switch 43 is turned on to turn on the daytime operation lamp 43a. When the daylight is bright, a predetermined voltage pulse is output to the output terminal 5 in the same manner as described above. In the night operation mode, the night operation switch 44 is turned on to turn on the night operation lamp 44a. When the night is dark, a predetermined voltage pulse is output to the output terminal 5 in the same manner as described above. Thus, the current operation mode can be confirmed by lighting the lamps 42a, 43a, and 44a. Note that any operation means such as a relay circuit or mechanical means may be used for the operation mode switching operation, and it is not necessary to be limited to specific means.

  The day and night are detected by the optical sensor 11. That is, the optical sensor 11 is made of, for example, CdS, detects the brightness, and when it becomes darker than the predetermined brightness at sunset, in the daytime operation mode, the application of the predetermined voltage is stopped and the night operation is performed. In the mode, application of a predetermined voltage is started. In addition, when the brightness is changed from a dark state such as dawn, application of a predetermined voltage is started in the daytime operation mode, and application of the predetermined voltage is stopped in the night operation mode.

  Further, as shown in FIG. 4, the main power switch 41 is configured as a tact switch, and in this embodiment, the distance between the pressing portion 41a and the contact point 41b is long. The main power switch is easily pushed more strongly than necessary, and the switch sometimes breaks. By configuring the switch in this way, the pressing force is absorbed by the bending of the member between the pressing portion 41a and the contact point 41b. And improved durability has been achieved.
