Since it is provided in the pipe, the chicken in the chicken cage can drink the water in the water supply pipe through the chicken spout. However, since there is a lot of garbage and dust in the poultry house, garbage and dust can easily enter the water supply pipe. And the like may adhere to and accumulate in the pipe, thereby clogging the water supply pipe. When the water supply pipe is clogged, the water pressure in the pipe decreases and the chickens in the chicken cage cannot drink enough water in the pipe. For this reason, a transparent pipe for detecting the water level extends upward so that the water level on the water surface moves up and down in accordance with the water pressure in the water supply pipe, and the transparent pipe for detecting the water level is provided. Inside, a float for detection, etc. is put and floated on the water surface, and the state of the float for detection by the worker (that is, the water level of the water surface in the transparent pipe for water level detection, with respect to a predetermined water level, By observing whether it is at the upper position or the lower position), an abnormality in the water supply pipe, for example, a decrease in water pressure due to clogging in the water supply pipe is monitored.

[0003] However, as described above, the environment inside the poultry house is not good, and dirt and dust adhere to the transparent pipe for detecting the water level, the transparency of the pipe decreases, and the state of floating for detection is observed. Can be difficult to do. In addition, recent poultry houses have been enlarged to accommodate a large number of chickens, and there are also many places to install transparent pipes for detecting the water level, so workers are required to float on the water surface inside the transparent pipes. It took time and effort to observe and turn around.

The present invention has been made to solve the above-mentioned defects, and an object of the present invention is to detect a floating state for detection floating on a water surface in a transparent hollow body such as a transparent pipe for detecting a water level. An object of the present invention is to provide a water level detection device that can easily know the abnormality and normality of a water supply pipe without requiring the trouble of observing each time.

[0005]

The water level detecting device used in the poultry house water supply device according to the present invention has the following configuration to achieve the above object.

That is, the invention according to claim 1 provides a water supply pipe provided near a chicken cage and a water supply pipe so that chickens in the chicken cage can drink water in the water supply pipe. A plurality of chicken drinking ports provided, and a water level detection hollow body extending upward from a part of the water supply pipe, so that the water level on the water surface moves up and down according to the water pressure in the water supply pipe. A water level detection device used in a poultry house water supply device comprising a water level detection device is provided in the water level detection hollow body or outside the hollow body, detects the water level of the water surface in the detection hollow body, A sensor for outputting a signal corresponding to the water level to a display or a notification device for displaying or notifying whether or not the water level is abnormal is provided. Since the water level of the water surface in the water level detection hollow body moves up and down according to the water pressure in the water supply pipe, and the sensor detects the water level of the water surface of the water level detection hollow body, and outputs a signal corresponding to the water level, The display or notification device displays or notifies whether or not the water pressure state in each water supply pipe is abnormal based on the detection of the detected water level on the water surface.

[0007] Also, as in the invention according to claim 2, the sensor includes a pair of conductive members which are put into the hollow body for detecting water level, and the pair of conductive members is hollow for detecting water level. The body may be separated by a certain distance in the vertical direction in the body. Since the pair of conductive members are vertically separated from each other by a predetermined distance in the hollow body for detecting the water level, when the lower part of the upper conductive member sinks to the surface of the water, the pair of conductive members pass through each other through water. Conducted between, the sensor detects such a water level in the water level detection hollow body and outputs a signal corresponding to the water level. On the other hand, when the upper part of the lower conductive member sinks to the water surface, but the lower part of the upper conductive member does not sink to the water surface, the lower part of the lower conductive member does not sink to the water surface. In the case of a water level, there is air or the like between the pair of conductive members to be in an electrically insulated state, so the sensor detects such a water level in the hollow body for detecting the water level and responds to the water level. The output signal is output.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a water level detecting device used in a poultry house water supply device according to the present invention will be described below with reference to the drawings.

As shown in FIG. 1, the poultry house water supply apparatus 3 is provided in a poultry house H for breeding chickens in a poultry cage 4. In the poultry house H, a water supply pipe 5 is provided. A plurality of chicken cages 4 are installed in a substantially horizontal direction, and are installed near a plurality of juxtaposed chicken cages 4. At the lower side of the water supply pipe 5, a plurality of chicken drinking ports 6 are provided at predetermined intervals along the longitudinal direction so that chickens in the chicken cage 4 can drink water in the water supply pipe 5. It is provided in. The chicken spout 6 has, for example, a structure in which a water guide shaft 6b is vertically movably fitted in a lower hole (not shown) of a water receiver 6a.
Of the water receiver 6a closes the lower hole of the water receiver 6a.
While the water in the inside is prevented from falling, the chicken in the poultry cage 4 pecks the water guide shaft 6b from below with its beak, whereby the water guide shaft 6b moves up and down, and the surface of the water guide shaft 6b is moved. As a result, the water in the water receiver 6a drips. However, the chicken spout 6 is not limited to the above structure, and any other structure can be used as long as the chicken in the chicken cage 4 can drink water in the water supply pipe 5. It may be configured.

A water level detection pipe 7 as a water level detection hollow body extends upward from a part of the water supply pipe 5 (in this case, a side end of the water supply pipe 5). Since the inside of the water level detection pipe 7 communicates with the inside of the water supply pipe 5, the water level S on the water surface moves up and down according to the water pressure in the water supply pipe 5. At the other end of the water supply pipe 5, a water supply source (not shown) for supplying water into the water supply pipe 5 is provided, and this water supply source supplies water at a substantially constant water pressure into the water supply pipe 5. Therefore, the water level S of the water surface in the water level detection pipe 7 is substantially constant as long as the water pressure does not drop due to clogging of the water supply pipe 5 with dust or the like. However, the water level detection pipe 7 for detecting the water pressure in the water supply pipe 5
Since the chickens in the poultry cage 4 drink the water in the water supply pipe 5, it is desirable that the number of the water level detection pipes 7 be one in consideration of safety. 5 may be provided, and the installation position of the water level detection pipe 7 does not necessarily need to be provided at the side end of the water supply pipe 5, and may be provided at the center thereof if necessary. Is also good.

A sensor 9 is provided in the water level detection pipe 7, and the sensor 9 detects a water level S on the water surface in the water level detection pipe 7, and outputs a signal corresponding to the water level S. Is output. That is, the water level detection pipe 7
The sensor 9 is inserted from above the
Since the water level S of the water surface in the inside moves up and down according to the water pressure in the water supply pipe 5, if the water level S1 is such that the sensor 9 sinks on the water surface, the water level S1 of the water surface is detected and the water level of the water surface is detected. While a signal corresponding to S1 (eg, an ON signal) is output, if the sensor 9 is at a water level S2 at which the water level does not sink, the water level S2 of the water surface is detected and the water level S of the water surface is detected.
2 (for example, an OFF signal).
When the water level S of the water surface in the water level detection pipe 7 is the above-mentioned water level S1, the water pressure in the water supply pipe 5 is normal, whereas the water level S in the water level detection pipe 7 is normal.
However, when the water level is the above-mentioned water level S2, since the water pressure in the water supply pipe 5 is abnormal, a signal (for example, an ON signal) corresponding to the water level S1 becomes a signal indicating normality, and a signal corresponding to the water level S2 ( For example, the OFF signal) is a signal indicating an abnormality. Note that a signal generated when the sensor 9 fails and a break in the conducting wires D1, D2, etc. described later occurs.
A signal indicating an abnormality corresponding to the water level S2 (for example, OF
F signal) and the same signal (for example, OFF signal)
Since the failure of the sensor 9 and the disconnection of the conductors D1, D2, etc. can be detected, abnormality other than the abnormality of the water pressure in the water supply pipe 5 can also be detected.

More specifically, the sensor 9 is shown in FIG.

When both of the pair of conductive members 11 are submerged in water, , Both conductive members 11 are electrically conductive through water (for example, ON).
On the other hand, when there is an insulator such as air between both of the pair of conductive members 11, both conductive members 11 are in an electrically insulated state (for example, OFF state).

As a result, when the water level S1 is such that the lower part of the upper conductive member 11a sinks on the water surface, the pair of conductive members 1a
The weak current flows through the water between the pair of conductive members 11 and the pair of conductive members 11 is in a conductive state (for example, an ON state). As a result, the sensor 9 detects such a water level S1 in the water level detection pipe 7, and outputs a signal (for example, an ON signal) corresponding to the water level S1 on the water surface. On the other hand, the water level S3 is such that the upper part of the lower conductive member 11b sinks to the water surface, but the lower part of the upper conductive member 11a does not sink to the water surface.
In the case of the water level S2 such that the lower portion of the lower conductive member 11b does not sink to the water surface, the pair of conductive members 11
Are in an electrically insulated state (for example, OFF state) due to the presence of air or the like, the sensor 9 detects such a water level S (S2, S3) in the water level detection pipe 7. Then, a signal (for example, an OFF signal) corresponding to the water level S (S2, S3) is output.

Incidentally, the pair of conductive members 11 is not limited to the above-mentioned shape and material, and various other changes are possible. The sensor 9 does not necessarily need to be composed of the pair of conductive members 11 and the like. For example, an optical sensor or a mechanical sensor may be used as long as it can detect the water level S of the water surface in the water level detection pipe 7, and any other configuration may be used. The sensor 9 is

1 and the other-side connection portion C2, and by connecting the one-side connection portion C1 to the other-side connection portion C2, the other end of the sensor unit U is electrically connected to the display or notification device 10 via the conductive wires D2 and D3. Connect to On the other hand, one-side connection portion C
1 is detached from the other-side connection portion C2, so that the one-side connection portion C1, the conductor D2, the sensor unit U, and the conductor D
If any one of the sensor 1 and the sensor 9 breaks down, all of the one-side connection portions C1 to the sensor 9 can be easily and integrally replaced, so that there is no trouble in repair.

The display or notification device 10 electrically connected to the sensor 9 via the conductor D3, the pair of connecting portions C, the conductor D2, the sensor unit U, and the conductor D1, etc. Although it is displayed or notified whether or not the water level S is abnormal, in the case of this embodiment,
Since a plurality of water supply pipes 5 are provided, the display or notification device 10 is electrically connected to the sensor 9 of each water level detection pipe 7 so as to correspond to each of the plurality of water supply pipes 5. Each is connected. That is, as described above, the signal (for example, the ON signal) corresponding to the above-described water level S1 is a signal indicating normality, and the above-described water levels S2 and S2
The signal corresponding to 3 (for example, OFF signal) is a signal indicating an abnormality, and these sensors 9 are connected so that each sensor 9 outputs the signal to the display or notification device 10 via the sensor unit U or the like. Therefore, the display or notification device 10 is based on the detection of the detected water level S on the water surface,

By using the 2b and the normal display unit 12c, it is possible to individually display the abnormality or the normal corresponding to each of the water supply pipes 5 among the plurality of water supply pipes 5. Then, if the individual display or notification device 12 is installed in an office or the like remote from the poultry house H, the worker can supply the water pipe 5 in the office without having to look around the poultry house H. You can see abnormalities. In addition, an individual display or notification device 1

An error or normal can be displayed or notified, and a buzzer alarm can be output. In addition, the installation place of the whole display or notification device 13 may be installed in the office or the like, or may be installed in other places.

However, the display or notification device 10
It is not always necessary to provide both the individual display / notification device 12 and the whole display / notification device 13, and it may be provided with only one of the individual display / notification device 12 or the whole display / notification device 13.

On the other hand, the entire display or notification device 13 does not necessarily need to be formed of a collective alarm panel or the like that can output a buzzer alarm. When at least one of the plurality of water supply pipes 5 is abnormal, sound or light is used. Any other configuration may be used as long as an abnormality can be displayed or notified so as to call attention to an operator or the like. Further, the entire display or notification device 13 does not need to be connected to only one display panel. For example, the entire display or notification device 13 is connected to a plurality of display panels, and collectively displays or notifies abnormalities or normalities of the display panels. May be configured.

A computer 14 that can control and manage a water level detecting device used in the poultry house water supply device 3 is connected to the individual display or notification device 12. Alternatively, it may be configured to store a normal state or the like.

Since the sensors are connected, each sensor detects the water level of the corresponding water level detection hollow body and outputs a signal corresponding to the water level. Based on this, the display or notification device can display or notify the water pressure state in each water supply pipe, so that the worker or the like can collectively know the water pressure state in each water supply pipe by the display or notification device. .

According to a fourth aspect of the present invention, the display or notification device includes an individual display or notification device and an entire display or notification device, and the individual display or notification device includes a plurality of water supply devices. While the abnormality or normal can be individually displayed or notified in response to each of the water supply pipes in the pipe, the overall display or notification device is provided when at least one of the plurality of water supply pipes is abnormal. Since the abnormality can be displayed or notified as a whole, the worker can first determine whether the entire water level detection device is abnormal or normal by, for example, the entire display or the notification device, and then perform a plurality of water supply pipe operations.
