[0021] Embodiment 1, in combination Figures 1 to 2 According to the waterproof layer leakage detector, the signal generator is configured to output the test signal, and the signal absorption line is arranged in a closed manner on the detection area, so that the signal detector and the probe rod can move in the detection area.

[0022] The signal generator 1 is configured to output the test signal, and the positive electrode of the signal generator 1 is connected to the lightning belt 7 of the waterproof layer to be detected through the positive signal output line 2, and the negative electrode of the signal generator 1 is connected to the signal absorption line 4 through the negative signal output line 3.

[0023] The signal absorption line 4 is arranged in a closed manner on the detection area.

[0024] One end of the signal detector 5 is connected to the signal absorption line 4 through a wire;

[0025] The other end of the signal detector 5 is connected to the tip of the probe rod 6 through a wire.

[0026] In the preferred embodiment, the signal generator 1 comprises a power supply 1-1, a voltage adjustment button 1-2 and a waveform selection button 1-3.

[0027] The power supply 1-1 is arranged inside the signal generator 1 to provide power for the signal generator 1 to output test signals.

[0028] The voltage adjustment button 1-2 and the waveform selection button 1-3 are arranged on the top of the signal generator 1, respectively, wherein the voltage adjustment button 1-2 is used to adjust the voltage value of the test signal output by the signal generator 1, and the waveform selection button 1-3 is used to adjust the type of the test signal output by the signal generator 1.

[0029] In the preferred embodiment, the signal generator 1 is used to output test signals in the form of direct current signals, alternating current signals or pulse signals.

[0030] In this embodiment, the roof waterproofing is described, the roof includes a structural layer, which is a reinforced concrete structure, used to bear the upper thermal insulation layer, slope layer, leveling layer and waterproof protective layer; since the waterproof layer has insulation, and the structural layer is a reinforced concrete structure, the structural layer has conductivity due to water leakage or damp; the waterproof protective layer is a steel mesh concrete structure, which also has conductivity due to rain or air humidity, and can be artificially wet according to needs, so the waterproof protective layer also has conductivity; this is equivalent to two conductive layers sandwiching an insulating layer, under the condition that the waterproof layer is not damaged, the waterproof protective layer and the structural layer are not conductive, and have high resistance.

[0031] The working principle of the waterproof layer leakage detector according to the embodiment is as follows:

[0032] The positive pole of the signal generator 1 is connected to the lightning strip 7 of the waterproof layer to be detected through the positive pole signal output line 2. Since the lightning strip 7 is connected to the building frame, and the building frame is connected to the structural layer of the floor, the lightning strip 7, the building frame and the structural layer are all conductive. Therefore, the positive pole of the signal generator 1 is connected to the structural layer through the positive pole signal output line 2. The negative pole of the signal generator 1 is connected to the signal absorption line 4 through the negative pole signal output line 3. The signal absorption line 4 is made of a corrosion-resistant bare metal material. The signal absorption line 4 is arranged in a closed manner with the head connected to the tail on the detection area. The signal absorption line 4 can be arranged in a square, circular or other shape, and the signal absorption line 4 is covered with mud and water to increase the conductivity of the signal absorption line 4 and the waterproof layer. In this way, two electrodes of the insulating layer (waterproof layer) are connected to the power supply. If the waterproof layer is damaged and leaks, the structural layer and the waterproof layer form a path, and current will flow through the path.

[0033] The signal detector 5 has two signal input ends. One signal input end is connected to the signal absorption line 4, and the other signal input end is connected to the end of the probe rod 6 through a wire. The front end of the probe rod 6 contacts the wet waterproof layer to find the point with the maximum voltage value. Since the waterproof layer is conductive, but its own resistance is relatively large, the point with a relatively large voltage value is the leakage point of the damaged waterproof layer.

[0034] Specific implementation method two, combined Figure 3 The waterproof layer leakage detector includes a signal generator 1, a positive pole signal output line 2, a negative pole signal output line 3, a signal absorption line 4, a signal detector 5 and a probe rod 6.

[0035] The signal generator 1 is used to output a test signal. The positive pole of the signal generator 1 is connected to the lightning strip 7 of the waterproof layer to be detected through the positive pole signal output line 2. The negative pole of the signal generator 1 is connected to the signal absorption line 4 through the negative pole signal output line 3.

[0036] The signal absorption line 4 is arranged in a closed manner with the head connected to the tail on the detection area.

[0037] One end of the signal detector 5 is connected to the signal absorption line 4 in a wireless manner.

[0038] The end of the probe rod 6 is connected to the other end of the signal detector 5 through a wire, and the detector 5 is fixed to the end of the probe rod 6.

[0039] In the preferred embodiment, the signal generator 1 includes a power supply 1-1, a voltage adjustment button 1-2 and a waveform selection button 1-3.

[0040] The power supply 1-1 is arranged inside the signal generator 1, and is used to provide power for the signal generator 1 to output the test signal;

[0041] The voltage adjustment button 1-2 and the waveform selection button 1-3 are arranged on the top of the signal generator 1 respectively, wherein the voltage adjustment button 1-2 is used to adjust the voltage value of the test signal output by the signal generator 1, and the waveform selection button 1-3 is used to adjust the type of the test signal output by the signal generator 1.

[0042] In the preferred embodiment, the signal generator 1 is used to output a direct current signal, an alternating current signal or a pulse signal as the test signal.

[0043] In the embodiment, the signal generator 1 is set to the pulse mode by the waveform selection button 1-3, the switch of the signal generator 1 is turned on, and the test signal (pulse signal) is transmitted to the signal absorption line 4 through the negative signal output line 3, and then transmitted to the waterproof protective layer through the signal absorption line 4. The pulse signal is transmitted to the lightning belt 7 through the positive signal output line 2, and then transmitted to the structural layer through the lightning belt 7. If the waterproof layer leaks, the structural layer and the waterproof protective layer form a power supply loop. Since the waterproof protective layer itself has a large resistance, different intensity pulse signals are formed on the waterproof protective layer. Since the pulse signal can emit pulse waves around, when the handheld signal detector 5 searches for the leakage point in the detection area, the pulse signal enters the signal detector 5 through the probe rod 6, and the signal detector 5 and the human body form a loop. The change of signal distribution intensity will make the signal detector 5 emit a signal with varying intensity. The place with strong pulse signal is the leakage point, that is, the damaged waterproof layer.
