When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0049] Since the urban drainage network is a severely humid environment, when monitoring devices such as liquid level, flow, and water quality are placed in inspection wells for a long time to monitor the status of the drainage pipes, sewage and water vapor can easily invade the interior of the device, causing the device to short-circuit.

[0050] In order to at least solve the above-mentioned problems, an embodiment of the present application provides a condensation alarm device for an inspection well waterproof box, which can effectively monitor the moisture condition inside the inspection well.

[0051] See also Figures 1 to 3 As shown, a condensation alarm device B for an inspection well waterproof box provided by an embodiment of the present application, the condensation alarm device is arranged inside the inspection well waterproof box A, and the condensation alarm device B comprises a condensation cavity 1, a condensation body 2 and a warning electrode 3; a refrigeration unit 11 and a cooling pipe 12 are arranged in the condensation cavity 1, and the cooling pipe 12 connects the condensation body 2 and the refrigeration unit 11 respectively, and the refrigeration unit 11 condenses the water vapor collected on the condensation body 2 through the cooling pipe 12; and

[0052] The warning electrode 3 is disposed at one end of the condensation body 2 , and the warning electrode 3 monitors and warns the capacitor disposed at the other end of the condensation body 2 .

[0053] Specifically, the refrigeration unit 11 includes a semiconductor refrigeration sheet. The semiconductor refrigeration sheet includes a hot end, a semiconductor layer and a cold end, the semiconductor layer is provided with a current input port and a current output port, and the hot end, the semiconductor layer, the cold end and the cooling pipe 12 are stacked from bottom to top in the condensation chamber 1.

[0054] For details, please continue to refer to Figures 1 to 3 As shown, the refrigeration unit 11 is a semiconductor refrigeration sheet, wherein the two terminals (current input port and current output port) of the semiconductor layer are respectively arranged outside the condensation chamber 1 (see Figure 1). The semiconductor refrigeration sheet is made of many N-type semiconductor and P-type semiconductor particles arranged one another, and the NPs are connected by a common conductor to form a complete circuit, usually copper, aluminum or other metal conductors. The bottom of the semiconductor refrigeration sheet is attached with a heat-conducting metal as a hot end, and the top is connected to the cooling tube 12 as a cold end. The water vapor collected on the condenser 2 is condensed through the cooling tube 12.

[0055] For further information, please refer to Figures 1 to 3 As shown, the condenser 2 includes a first condenser 21 and a second condenser 22 ; the first condenser 21 and the second condenser 22 are made of metal.

[0056] Please continue reading Figures 1 to 3 As shown, the cooling pipe 12 is a bent pipeline design structure, one end of the bent wire structure is connected to the cold end of the refrigeration unit 11, and the cold energy generated by the cold end is transferred to the condenser connected to the other end.

[0057] Furthermore, the exterior of the cooling pipe 12 includes a heat-insulating layer, and the heat-insulating layer can completely wrap the cold end to reduce the refrigeration consumption of the cold end, thereby further improving the energy-saving effect.

[0058] Specifically, the cooling pipe 12 includes a first cooling pipe 121 and a second cooling pipe 122. The first cooling pipe 121 is respectively connected to the cold end of the refrigeration unit 11 and the first condenser 21, and the first cooling pipe 121 transfers the cold energy of the cold end to the first condenser 21 connected to the other end, so that the water vapor around the first condenser 21 condenses on the first condenser 21.

[0059] Specifically, the second cooling pipe 122 is connected to the cold end of the refrigeration unit 11 and the second condenser 22 respectively, and the second cooling pipe 122 transfers the cold energy of the cold end to the second condenser 22 connected to the other end, so that the water vapor around the second condenser 22 condenses on the second condenser 22. Figures 1 to 3 As shown, one end of the first condensation body 21 is a first capacitor 211 arranged on a flat vertical section, and the other end is a first warning electrode 31; one end of the second condensation body 22 is a second capacitor 221 arranged on a flat vertical section, and the other end is a second warning electrode 32.

[0060] When water vapor condenses on the first condensation body 21 and the second condensation body 22 , the dielectric between the first condensation body 21 and the second condensation body 21 changes, and the first warning electrode 31 and the second warning electrode 32 generate a condensation alarm.

[0061] Please continue reading Figures 1 to 3As shown, the first condensation body 21 and the second condensation body 22 are arranged at an angle, and the slope of the first condensation body 21 is smaller than that of the second condensation body 22. Thus, the first condensation body 21 condenses water vapor under short-term high humidity conditions, and the second condensation body 22 achieves rapid sliding of liquid under long-term low humidity conditions. By setting different inclination angles, the condensation body 2 can realize condensation alarm for different scenarios.

[0062] Furthermore, the upper part of the condenser 2 is flat, and the lower part adopts a rounded structure design. In this way, when water vapor condenses on the condenser 2, the rounded structure design can facilitate the condensed water to flow downward.

[0063] Furthermore, in order to enable the condensation alarm device to achieve a heat preservation effect, the first warning electrode 31 and the second warning electrode 32 are carbon non-conductive dew point electrodes.

[0064] Furthermore, the condenser 2 is provided with graphite conductive heat-insulating material, thereby reducing electrochemical corrosion at the power connection.

[0065] The condensation alarm device provided in the above-mentioned embodiment of the present application realizes refrigeration through the refrigeration unit 11, and transports cold air from the first cooling pipe 121 and the second cooling pipe 122 to the first condensation body 21 and the second condensation body 22 respectively. When the first condensation body 21 and the second condensation body 22 collect water vapor, due to the relatively low temperature, the water vapor will be quickly condensed on the first condensation body 21 and the second condensation body 22, and changed from gas to liquid.

[0066] Please continue reading Figures 1 to 3 As shown, the first condensation body 21 and the second condensation body 22 are inclined and have different slopes. In addition, there is a gap between the bottom ends of the first condensation body 21 and the second condensation body 22. When the water vapor collected on the first condensation body 21 and the second condensation body 22 condenses into liquid, it will automatically flow downward along the first condensation body 21 and the second condensation body 22. At this time, liquid will gather on the first capacitor 211 and the second capacitor 221 located at the bottom ends of the first condensation body 21 and the second condensation body 22, respectively. Since the first condensation body 22 and the second condensation body 23 are made of metal, the first condensation body 22 and the second condensation body 23 will be conductive. At this time, the first warning electrode 31 and the second warning electrode 32 will monitor the capacitance changes of the first capacitor 211 and the second capacitor 221 to achieve an alarm effect.

[0067] That is, when the first condensation body 21 and the second condensation body 22 collect water vapor, it will condense quickly and flow downward. At this time, the first condensation body 21 and the second condensation body 22 are connected, and the first warning electrode 31 and the second warning electrode 32 will monitor the capacitance change of the first capacitor 211 and the second capacitor 221, thereby realizing the alarm function.

[0068] Please continue reading Figures 1 to 3 As shown, the condensation alarm device includes a heat-insulating base 4 , and the heat-insulating base 4 is arranged below the condensation cavity 1 .

[0069] Furthermore, the metal heat conducting sheet in the condensation cavity 1 is arranged on the heat insulation base 4. The heat conducting base can enhance the dissipation of the metal heat conducting sheet (hot end) as much as possible, further reduce the cost, and realize the sustainable condensation alarm function.

[0070] In some embodiments, the heat-insulating base 4 is made of foam material and has a certain mechanical strength.

[0071] Please continue reading Figures 1 to 3 As shown, a fixing hole 41 is provided on the heat-insulating base 4 , and the condensation alarm device is fixed inside the inspection well waterproof box A through the fixing hole 41 .

[0072] Please continue reading Figures 1 to 3 As shown, a water storage box 42 is provided on the heat preservation base 4, and the water storage box 42 is located below the condensation body 2; after the water vapor collected on the condensation body 2 is condensed, it flows downward into the water storage box 42. When the first condensation body 21 and the second condensation body 22 collect water vapor, it will condense quickly and flow downward. Since there is a gap between the bottoms of the first condensation body 21 and the second condensation body 22, when the condensed water flows downward from the first condensation body 21 and the second condensation body 22, it will drip into the water storage box 42.

[0073] In some embodiments, the water storage box 42 performs chemical water storage. Water-absorbing materials are placed in the water storage box 42 to store condensed water.

[0074] In some embodiments, the condensation alarm device further includes a power supply module, and the power supply module is used to supply power to the entire condensation alarm device so that the device can operate normally.

[0075] See also Figures 4 to 7As shown, the inspection well waterproof box A includes a box body A1 and a box cover A2; a waterproof rubber gasket A3 is provided between the box body A1 and the box cover A2; a groove is engraved on the waterproof rubber gasket A3, a flat metal wire is embedded in the groove, and contacts at both ends of the metal wire extend to the inside of the box body, the closest distance between the two ends of the metal wire is less than 2 mm, and the groove is left at the closest point.

[0076] If sewage enters the inspection well waterproof box A, the sewage will first spread along the groove on the waterproof rubber gasket A3. At this time, since the sewage has a certain conductivity, the metal wire on the groove will change its resistance. At this time, by detecting the partial pressure of the metal wire, it can be warned whether the box body has water. At this time, the inspection well waterproof box A can directly monitor whether sewage enters the box body A11, and the internal condensation alarm device B can monitor water vapor. Together, the two ensure the normal operation of the monitoring device inside the inspection well waterproof box A.

[0077] Please continue reading Figure 5 As shown, a fixing column A11 is provided at the bottom of the box body A1, and a fixing hole 42 is provided on the insulation base 4 of the condensation alarm device B, which is fixed to the fixing column A11, so that the condensation alarm device is fixed to the bottom of the box body A1, so that the condensation alarm device B is arranged in the inspection well waterproof box A and is tightly attached to the inspection well waterproof box A to facilitate heat dissipation to the outside.

[0078] In some embodiments, the inspection well waterproof box A may be equipped with IoT monitoring devices such as liquid level, flow, and water quality to collect relevant data of the drainage system for measuring the operating status of the urban drainage network. At this time, the condensation alarm device B installed inside the inspection well waterproof box A can effectively detect the water vapor inside the box body A11 to avoid short circuit of IoT monitoring devices such as liquid level, flow, and water quality.

[0079] The condensation alarm device provided in the above embodiment of the present application can be placed in the inspection well waterproof box. At this time, the inspection well waterproof box A will be able to directly monitor whether sewage enters the box body A11, and the internal condensation alarm device B can monitor water vapor. The condensation alarm device and the inspection well waterproof box together ensure the normal operation of the monitoring device inside the inspection well waterproof box A, avoiding the phenomenon of short circuit due to moisture.
