The wiring connected to the is stored.
[0011]
The simulated valve panel 4 includes the pressure display unit 3 and a first valve 10 and a second valve 11. It is desirable that the simulated valve panel 4 has the same appearance as that used in the actual track. A pair of simulated pressure oil tanks 13 and 13 are drawn on the front wall of the casing 9 near both ends of the simulated OF cable line 2. 14 is a valve of the simulated pressure oil tank 13 attached to the front wall.

For indicating (answering) an oil leakage location and a training completion button 26 is provided. 19 is a buzzer, and 20 is a signal lamp.
[0013]
Accordingly, as shown in FIGS. 1 to 3, an instructor setting input unit 21 including a monitor panel 23 is provided on the left side wall of the casing 9. The setting input unit 21 can set and input various setting condition data including an oil leakage location to the control unit 22 to be described later by the monitor panel 23, and correct / false judgment and stop of the setting condition data, the answer data, and the answer data. The open / close state of each valve such as the valve 1 and the oil discharge valve 8 can be displayed.
[0014]
More specifically, the monitor panel 23 shows an oil flow path diagram connecting the simulated OF cable line 2, the simulated valve panels 4 and 4, and the simulated pressure oil tanks 13 and 13, and the set oil leakage points and The open / close state of each valve, electrical numerical values as simulated hydraulic pressure, and the like are displayed. In addition, the monitor panel 23 is provided with setting input switches 24 for inputting setting condition data such as an oil leakage location (A, B, C), an oil leakage amount, a time limit, and the course from the start of training. Time, trainee's answer, training operation procedure, etc. are displayed.
[0015]
The control unit 22 is electrically connected to the instructor setting input unit 21, the trainee answer input unit 18, each stop valve 1,..., Each simulated valve panel 4, 4, the alarm receiving unit 16, and the like. In addition to inputting the set condition data, response data from the response input unit 18 and open / close signals from the stop valves 1 are input.

And correctness determination data is transmitted to the setting input unit 21.
[0016]
Thus, this oil leakage section exploration training apparatus constitutes a simulated OF cable oil flow path on the front side, but the back side (inside the casing 9) is the first and second valves 10, 11 of the simulated valve panel 4. In addition, an electrical opening / closing detector (not shown) such as a potentiometer that detects the opening / closing position of the valve 14 of the simulated pressure oil tank 13 and the control unit 22 are provided.
[0017]
Next, the procedure of oil leakage section exploration training (simulation training) using the OF cable oil leakage section exploration training apparatus according to the present invention will be described with reference to the flowcharts of FIGS. 1 to 3 and 4. First, after confirming that there is no abnormality in the apparatus, the instructor sets the apparatus to an initial state. That is, each stop valve 1..., The first valve 10, 10, the second valve 11, 11 and the valve 14, 14 are set to the origin position (open state), and the oil discharge valves 8, 8 are set to the origin position (closed state). To.
[0018]
When the initial setting is completed, the instructor checks whether the indicator lights, buzzers, and switches of the alarm receivers 16 and 16 are operating normally. By operating 21, various setting condition data (oil leakage location, oil leakage amount and time limit) are input to the control unit 22. That is, one of the oil leakage points A, B, and C of the monitor panel 23 (corresponding to the three simulated cables 7a, 7b, and 7c of the simulated OF cable line 2) is selected, and the “oil leakage point setting” is selected. Press the setting input switch 24 to input the setting. In addition, for example, when trainees with a low level of proficiency perform training, the instructor sets the setting conditions according to the trainee at the setting input unit 21, such as setting the oil leakage amount to a small value and setting the time limit to 20 minutes. Select or adjust.
[0019]
Thus, the preparation of the apparatus is completed, and in this state, the pressure display units 3 and 3 of the simulated valve panels 4 and 4 are controlled to the initial state by the control unit 22. In other words, the pressure display unit 3 is a hydraulic gauge having a scale (unit MPa) and a needle on the surface, but is actually an electrical instrument such as a numeric display, a voltmeter, and a timer that are moved by electrical control. The position of the needle is electrically controlled to indicate the 0.2MPa scale. That is, an electrical numerical value (simulated hydraulic pressure value) is displayed on the pressure display unit 3 as the simulated hydraulic pressure. The monitor panel 23 is digitally displayed as 0.2 MPa.
[0020]
Thus, when the instructor presses the “training start” setting input switch 24 on the monitor panel 23, the training is started. That is, a simulated OF cable oil leakage accident occurs. In the simulated state of oil leakage, the electrical numerical values displayed on the pressure display units 3 and 3 are simulated to decrease at a speed equivalent to the pressure reduction speed of an actual OF cable oil leakage accident. The elapsed time is measured and displayed on the monitor panel 23 while being controlled by the control unit 22.
[0021]
After starting the training, the buzzer of the alarm receivers 16 and 16 makes the trainee immediately know that oil leakage has occurred, and press the buzzer stop button to stop the buzzer. At this time, the trainee confirms that the pressure display sections 3 and 3 of the simulated valve panels 4 and 4 display a pressure drop due to oil leakage (for example, 0.18 MPa or less).
[0022]
By the way, after the start of training, when the time limit is exceeded, when a valve that does not need to be operated is operated, when the oil drain valve 8 is opened, when the operation sequence of the valve is incorrect, When the pressure drop exceeds the specified limit value --- when the pressure value is less than 0.06 MPa, for example ---- an NG signal is sent from the control unit 22 to the instructor setting input unit 21, and the monitor panel 23 The contents of the training failure are displayed (not shown), and the training is immediately stopped.
[0023]
Next, the trainee uses the tool to close the stop valve 1 one after another, and looks at the pressure values of the left and right pressure display units 3 and 3 to find out where the oil leakage is. Incidentally, FIG. 5 shows the operation of opening and closing each stop valve 1 and the left and right pressure display sections 3 and 3 when oil leakage occurs in the simulated cable 7b (oil leakage location B) of the simulated OF cable line 2. It is a time chart which shows the relationship with a pressure value.
[0024]
1 and 5, when the stop valve (SV) 1 a is first closed, the pressure value drop of the right pressure display unit 3 stops and stabilizes, but the pressure value of the left pressure display unit 3 is stabilized. Continues to descend. When SV1a is opened and returned to the origin position, the right pressure value decreases again. In order to prevent separation, the closed stop valve 1 is opened and then the next stop valve 1 is closed.
[0025]
When SV1b is closed or SV1c is closed, the pressure value of the right pressure display unit 3 is stabilized, but the pressure value of the left pressure display unit 3 continues to decrease, as in SV1a. Next, when SV1d is closed, the pressure value of the right pressure display unit 3 continues to decrease and the pressure value of the left pressure display unit 3 stabilizes, and oil leakage occurs between SV1c and SV1d. It turns out that it is a location. In contrast to this, it is also possible to search from the left SV 1 f and search for the oil leakage location.
[0026]
The pressure drop during the oil leakage search is controlled by the control unit 22 as shown in FIGS. That is, the control unit 22 has a circuit configured to lower the pressure value displayed on each pressure display unit 3 and 3 at a speed equivalent to the pressure drop in the actual OF cable oil leakage accident, When a closing signal output by closing the stop valve 1 is input, the electrical value of one or the other pressure display unit 3 is stabilized based on the closing signal and the set condition data, and the closed stop valve 1 is closed. When an open signal output by reopening is input, the electrical value of one or the other pressure display unit 3 drops again based on the open signal and setting condition data.
[0027]
Alternatively, the control unit 22 can be configured with a simple electric circuit. For example, as described with reference to FIGS. 1 and 5, an electric circuit configuration in which oil leakage occurs in the simulated cable 7b of the simulated OF cable line 2 will be briefly described. In this case, between the stop valve 1c and the stop valve 1d, Then, the stop valves 1a, 1b, 1c and the pressure drop operation circuit of the right pressure display unit 3 are electrically connected in series so that the pressure drop of the left and right pressure display units 3, 3 is reversed between the left and right. A circuit configuration is formed by branching and electrically connecting the stop valves 1d, 1e, 1f and the pressure drop operation circuit of the left pressure display unit 3 in series.
[0028]
(Return to FIGS. 1 to 4) The trainee observes the pressure values of the pressure display parts 3 and 3 while using the tool to close and open the stop valves 1 one by one as described above, To explore. If the trainee can determine the oil leakage section, the trainee presses the answer button 25 that seems to be the correct answer from the plurality of answer buttons 25 provided in the trainee answer input unit 18, and sends the answer data to the control unit 22. To do. The control unit 22 compares the answer data with the setting condition data to make a correct / incorrect determination, and the response data and the correct / incorrect determination data are transmitted to the instructor setting input unit 21 and displayed on the monitor panel 23. At this time, if the answer is correct, the signal lamp 20 is turned on and the buzzer 19 is operated to notify the trainee that the answer is correct. If the answer is wrong, an NG signal is transmitted from the control unit 22 to the setting input unit 21 and the content of the training failure is displayed on the monitor panel 23. At the same time, the buzzer and the signal lamp are operated, and the answer is incorrect. Let the trainee know.
[0029]
After the answer is correct, the trainee next closes stop valves 1 and 1 at the shortest positions on both sides of the oil leakage section (stop valves 1c and 1d in the case of oil leakage point B), disconnects the oil leakage section, and responds. Press the training completion button 26 of the input unit 18. At this time, the control unit 22 determines whether or not the correct valve is closed, correct / incorrect determination of the separation operation is performed, and correctness determination data is transmitted to the setting input unit 21 and displayed on the monitor panel 23. If the detaching operation is correct, the signal lamp 20 is turned on and the buzzer 19 is operated to notify the trainee that the detaching operation is correct. Also, if the disconnection operation is wrong, an NG signal is transmitted from the control unit 22 to the setting input unit 21 and the content of the training failure is displayed on the monitor panel 23. At the same time, the buzzer and the signal lamp operate, and the disconnection operation is incorrect. Also inform the trainees that it was. If a valve that should not be operated, such as the oil drain valves 8, 8, is operated before the disconnection operation, or if an operation procedure error or operation error is made, an NG signal is input from the control unit 22 The content of the training failure is displayed on the monitor panel 23 and transmitted to the unit 21, and the training is immediately stopped.
[0030]
When the training is completed, the instructor can set the device again to the initial state (as described above), complete the preparation, and start the next training quickly. That is, the training can be easily repeated any number of times, and different patterns (setting conditions) can be easily set.
[0031]
Thus, the OF cable oil leakage section exploration training apparatus of the present invention has the same components as those used in the actual line: the simulated OF cable line 2, the simulated valve panels 4 and 4, the alarm. It is equipped with receivers 16 and 16, etc., and is configured to create a simulated state of oil leakage without using oil, and to generate a pressure drop phenomenon, etc. in real life. Experiences close to accidents are possible, and extremely practical training is possible. At this time, since no oil is used, the trainee does not get dirty with oil, and the device and its surroundings become dirty with oil, and the maintenance of the device is easy.
[0032]
Further, since the open / closed states of the stop valves 1... And the simulated valve panels 4 and 4 are always detected by electric signals, it can be determined by the control unit 22 (computer) whether the operation of the trainee is accurate, and Instructor can check trainees' operation on the monitor panel 23 of the setting input unit 21. Skills / techniques to correctly handle each oil spill accident by giving appropriate guidance to each trainee. Can be acquired in a short period of time.
[0033]
The present invention is not limited to the above-described embodiment. For example, in the present embodiment, the case of a three-core simulated OF cable line 2 is illustrated, but a simulated OF cable other than three cores (for example, a single core). An oil leakage section exploration training apparatus may be provided.
