Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise specified, the meaning of "a plurality" is two or more.
[0023] Some embodiments of the present utility model provide a device for monitoring the position of a water leakage point in a pipeline. As Figures 1 to 3As shown in the figure, the device for monitoring the location of a water leakage point in a pipeline includes: a first circuit 1, a plurality of water leakage monitoring units 2, a second circuit 3, a plurality of information feedback units 4, and a current monitoring unit 5. Among them, the positive and negative wires of the first circuit 1 are both arranged along the extension direction of the pipeline 6. The water leakage monitoring unit 2 is of an annular structure, and the water leakage monitoring unit 2 is sleeved on the pipeline 6. The water leakage monitoring unit 2 includes: a monitoring signal terminal 21, a monitoring positive terminal 22, and a monitoring negative terminal 23. The monitoring positive terminal 22 is electrically connected to the positive wire of the first circuit 1, the monitoring negative terminal 23 is electrically connected to the negative wire of the first circuit 1. The water leakage monitoring unit 2 is configured to collect the liquid leaking from the pipeline 6, and the monitoring signal terminal 21 emits a control signal. The positive and negative wires of the second circuit 3 are both arranged without following the extension direction of the pipeline 6. One information feedback unit 4 is arranged on one side of each water leakage monitoring unit 2. The information feedback unit 4 includes: a signal control terminal 41, a signal positive terminal 42, and a signal negative terminal 43; the signal positive terminal 42 is electrically connected to the positive wire of the second circuit 3, the signal negative terminal 43 is electrically connected to the negative wire of the second circuit 3, the signal control terminal 41 is electrically connected to the monitoring signal terminal 21. The information feedback unit 4 is configured to receive the control signal emitted by the monitoring signal terminal 21 and make the current path between the signal positive terminal 42 and the signal negative terminal 43 conductive. The current monitoring unit 5 is electrically connected to the negative wire of the second circuit 3, and the current monitoring unit 5 is configured to detect the magnitude of the current in the negative wire of the second circuit 3.
[0024] In some examples, the pipeline 6 can be arranged underground or in a wall. As the pipeline 6 ages or due to external forces, water leakage points may occur on the pipeline 6. Taking the case where the pipeline 6 is buried underground as an example, when there is a water leakage point or a seepage point on the pipeline 6, the liquid often seeps along the extension of the pipe wall.
[0025] A plurality of water leakage monitoring units 2 can be sleeved on the pipeline 6. The water leakage monitoring units 2 are arranged in sequence along the extension direction of the pipeline 6, and the distance between adjacent water leakage monitoring units 2 can be 50 cm to 100 cm. For example, the distance between adjacent water leakage monitoring units 2 is 50 cm, 75 cm, or 100 cm. One information feedback unit 4 is arranged on one side of each water leakage monitoring unit 2. The plurality of information feedback units 4 are numbered in sequence according to the extension direction of the pipeline 6. For example, starting from one end of the pipeline 6, the plurality of information feedback units 4 are numbered with natural numbers along the extension direction of the pipeline 6. It can be understood that the first circuit 1 and the second circuit 3 can be arranged along the extension direction of the pipeline 6. For example, both the first circuit 1 and the second circuit 3 are parallel to the pipeline 6. The first circuit 1 is also electrically connected to a power supply, and the plurality of water leakage monitoring units 2 are connected in parallel to the first circuit 1. The second circuit 3 can be electrically connected to a regulated power supply, and the plurality of information feedback units 4 are connected in parallel to the second circuit 3.
[0026] When there is a water leakage point or a water seepage point on the pipeline 6, the leaked liquid penetrates along the outer wall of the pipeline 6. When the liquid contacts one or more of the multiple water leakage monitoring units 2, the water leakage monitoring unit 2 that contacts the liquid provides a signal to the corresponding information feedback unit 4. After receiving the signal, the information feedback unit 4 conducts the positive wire and the negative wire of the second circuit 3. At this time, the current monitoring unit 5 detects that there is current passing through the negative wire of the second circuit 3, and it can be determined that there is a water leakage point on the pipeline 6. By judging the number of the information feedback unit 4, the position of the water leakage point on the pipeline 6 can be roughly judged.
[0027] In some embodiments, such as Figure 1 , Figure 3 and Figure 4 shown, the information feedback unit 4 further includes: a resistor 44 and a thyristor 45. One end of the resistor 44 is electrically connected to the signal positive terminal 42, the other end of the resistor 44 is electrically connected to the anode of the thyristor 45, the cathode of the thyristor 45 is electrically connected to the signal negative terminal 43, and the control electrode of the thyristor 45 is electrically connected to the signal control terminal 41.
[0028] In some examples, after one of the multiple water leakage monitoring units 2 contacts the liquid, the monitoring signal terminal 21 of the water leakage monitoring unit 2 transmits a control signal to the corresponding information feedback unit 4, that is, the monitoring signal terminal 21 can output a control signal to the control electrode of the thyristor 45. When the voltage of the control signal reaches the trigger voltage of the thyristor 45, the anode and the cathode of the thyristor 45 are conducted, that is, the information feedback unit 4 conducts the positive wire and the negative wire of the second circuit 3. Thus, the current monitoring unit 5 can detect that there is current on the negative wire of the second circuit 3, that is, there is a water leakage point on the pipeline 6.
[0029] It should be explained that after the water leakage monitoring unit 2 contacts the liquid, for the signal uploaded by the monitoring signal terminal 21, when some other situations occur, such as when the pipeline 6 stops leaking after leakage, as the liquid evaporates, the monitoring signal terminal 21 of the water leakage monitoring unit 2 stops uploading the signal. At this time, after the information feedback unit 4 receives the signal of the monitoring signal terminal 21, it is conducted, and after the monitoring signal terminal 21 stops uploading the signal, the information feedback unit 4 still remains in the conducting state, that is, when the staff does not deal with it in time, the information feedback unit 4 always remains in the conducting state. Only after the staff deals with the water leakage point and reconnects the disconnection between the second circuit 3 and the regulated power supply, the information feedback unit 4 can be in the cut-off state.
[0030] In some embodiments, the multiple information feedback units 4 are arranged in sequence along the extending direction of the pipeline 6, and the resistance values of the resistors 44 of the multiple information feedback units 4 increase or decrease along the extending direction of the pipeline 6.
[0031] In some examples, the resistance value of the resistors 44 of the multiple information feedback units 4 can increase as the number of the information feedback units 4 increases. Exemplarily, the resistance value of the resistor 44 of the first information feedback unit 4 is 100 Ω, the resistance value of the resistor 44 of the second information feedback unit 4 is 150 Ω, and so on. The resistance value of the resistor 44 of the nth information feedback unit 4 is 100 + 50n Ω. When one of the multiple information feedback units 4 is turned on, the current monitoring unit 5 can determine the number of the turned-on information feedback unit 4 by detecting the magnitude of the current, that is, can roughly determine the location of the water leakage point.
[0032] Of course, there may be a situation where two or three information feedback units 4 are turned on, thus forming a parallel circuit. By detecting the magnitude of the current, the parallel value of the resistances of the turned-on information feedback units 4 can be calculated, and through calculation, the numbers of the turned-on information feedback units 4 can be known, and the location of the water leakage point can be determined. For example, when the fifth information feedback unit 4 and the sixth information feedback unit 4 are both turned on, the resistance value on the second loop 3 is the parallel value of the resistor 44 of the fifth information feedback unit 4 and the resistor 44 of the sixth information feedback unit 4. Specifically, the parallel value of the resistor 44 of the fifth information feedback unit 4 and the resistor 44 of the sixth information feedback unit 4 is (400 + 350) / (400 * 350). That is to say, when the resistance value calculated by the current detected by the current monitoring unit 5 is (400 + 350) / (400 * 350), it can be determined that the fifth information feedback unit 4 and the sixth information feedback unit 4 are both turned on, and the location of the water leakage point on the pipeline 6 is between the fifth information feedback unit 4 and the sixth information feedback unit 4.
[0033] In some embodiments, as Figure 1 、 Figure 2 and Figure 4 shown, the water leakage monitoring unit 2 further includes: a water absorption ring 24, a first electrode plate 25, and a second electrode plate 26. Among them, the water absorption ring 24 is of an annular structure. The water absorption ring 24 includes an insulating material and is configured to absorb the liquid in contact therewith. The first electrode plate 25 is an arc-shaped plate member fixed inside the water absorption ring 24, and the first electrode plate 25 is electrically connected to the positive monitoring terminal 22. The second electrode plate 26 is an arc-shaped plate member fixed inside the water absorption ring 24, and a gap is provided between the second electrode plate 26 and the first electrode plate 25. The second electrode plate 26 is electrically connected to the negative monitoring terminal 23.
[0034] The water absorption ring 24 has elasticity.
[0035] The length of the water absorption ring 24 can be 5 to 20 cm. For example, the length of the water absorption ring 24 can be 5 cm, 15 cm, or 25 cm. The lengths of the second electrode sheet 26 of the first electrode sheet 25 are the same as the length of the water absorption ring 24.
[0036] In some examples, the water absorption ring 24 can be made of elastic sponge, which is convenient for absorbing liquid and insulates the first electrode sheet 25 and the second electrode sheet 26 when the water absorption ring 24 is in a dry state. After the water absorption ring 24 absorbs liquid, under the action of the liquid, the first electrode sheet 25 and the second electrode sheet 26 are conducted, achieving the purpose of uploading signals to the monitoring signal terminal 21.
[0037] It should be noted that affected by the type of liquid and the amount of liquid, the voltage of the signal uploaded by the monitoring signal terminal 21 is in a fluctuating state, and the control electrode of the thyristor 45 only needs the signal voltage uploaded by the monitoring signal terminal 21 to be greater than or equal to the trigger voltage to achieve the conduction of the anode and cathode of the thyristor 45.
[0038] In addition, in the present utility model, to improve the conductivity of the water absorption ring 24 after absorbing liquid, metal salts such as sodium carbonate or sodium chloride can be filled in the water absorption ring 24.
[0039] It also needs to be supplemented that in the present utility model, the so-called liquid is limited to conductive liquids such as tap water.
[0040] In some embodiments, the leakage point position monitoring device further includes a microprocessor, which is electrically connected to the current monitoring unit 5 and is configured to receive the signal uploaded by the current monitoring unit 5 and calculate the leakage position of the pipeline 6.
[0041] The microprocessor can be a single-chip microcomputer. Information on the conduction modes of the information feedback units 4 corresponding to different resistance 44 values can be written into the microprocessor, facilitating the microprocessor to match the numbers of the conductive information feedback units 4 according to the calculated resistance 44 value. Information on the positions of the pipelines 6 corresponding to different numbers of the information feedback units 4 can also be written into the microprocessor, facilitating the provision of possible leakage point positions to the staff.
[0042] The current monitoring unit 5 can be a digital ammeter and is electrically connected to the microprocessor.
[0043] In the description of this specification, specific features, structures, materials, or characteristics can be combined in a suitable manner in any one or more embodiments or examples.
[0044] The above are only the specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
