[0031] Figure 2 Structure diagram of the waterlogging and siltation detection device with protective cover and interactive trigger function;

[0032] Figure 3 Block diagram of the waterlogging and siltation automatic detection system. DETAILED DESCRIPTION

[0033] Example 1 - Basic waterlogging and siltation detection device

[0034] As shown in the figure, the basic waterlogging and siltation detection device A is composed of a shell 1, silt detection sensor heads 2, water detection sensor heads, a control circuit board (not shown) installed in the shell 1, a human-computer interaction device (not shown due to angle reasons), a power supply (not shown), and the like. Among them: Figure 1 The shell 1 is a doctor's hat type, with a flat top shell cap 11 and a cylindrical shell body 12 at the lower part; three openings are provided below the shell body 12, two of which are used for the silt detection sensor heads 2 to protrude out of the lower end of the shell, and the silt detection sensor heads 2 are provided with a first sealing element 13 at the lower end of the shell, and the other opening is a water detection hole 5, the inner wall of which is provided with an internal thread 51 and is equipped with a second sealing ring 52;

[0035] The water detection sensor head is composed of a cylindrical sleeve 3 and a metal spring 4; the lower end of the sleeve 3 is a sealed blind end, and the upper end is provided with an external thread 31 for screwing with the internal thread 51 on the water detection hole 5;

[0036] The metal spring 4 is electrically connected to the control circuit board (not shown) installed in the shell 1 through a metal strip 41.

[0037] After assembly, the two silt detection sensor heads 2 are sealingly installed at the lower part of the shell 1 and protrude out of the shell 1; the water detection sensor head is sealingly connected to the second sealing ring 52 through the external thread 31 of the sleeve 3, and is screwed to the internal thread 51 of the water detection hole 5 at the lower part of the shell body 12; inside the sleeve 3, the metal spring 4 is electrically connected to the control circuit board in the shell 1 through the metal strip 41.

[0038] In the device A, the control circuit board (not shown) is provided with a water detection circuit with a capacitive sensing chip as the core corresponding to the water detection sensor head; and an impedance detection circuit corresponding to the two silt detection sensor heads 2 is provided between the two silt detection sensor heads 2.

[0039]

[0040] ​In use, set monitoring points at the drainage channels, low-lying areas, etc. that need to be monitored, open mounting holes on the drainage channels that are equivalent to the shell body 12 of the device A, and set monitoring racks (with mounting holes for mounting the device on the top and exposed on the bottom) at the low-lying areas. Insert the silt detection sensor head 2 and the waterlogging detection sensor head and the shell body 12 of the device A into the mounting holes.

[0041] ① When the water level below the device A rises and submerges the silt detection sensor head 2 and the waterlogging detection sensor head, both sensor heads detect the "water" signal through the control circuit board; ② When the water level drops and the silt detection sensor head 2 and the waterlogging detection sensor head are out of the water layer, both sensor heads detect the "no water" signal through the control circuit board; ③ After experiencing a waterlogging flush, a silt layer appears below the device A, and the silt layer contacts the silt detection sensor head 2. After the water layer above the silt layer subsides for a period of time, whether the silt layer contacts the waterlogging detection sensor head or not, the waterlogging detection sensor head will detect the "no water" signal through the control circuit board due to the gradual decrease of the moisture in the silt layer, while the silt detection sensor head 2 detects the "water" signal through the control circuit board because the moisture in the silt layer provides a lower impedance for the two silt detection sensor heads 2.

[0042] The control circuit board determines the waterlogging and siltation of the monitored drainage channels, low-lying areas, etc. by the above three states and their change rules over time:

[0043] The above state ① - both the waterlogging detection sensor head and the silt detection sensor head 2 detect the "water" signal through the control circuit board: determine that there is waterlogging;

[0044] The above state ② - both the waterlogging detection sensor head and the silt detection sensor head 2 detect the "no water" signal through the control circuit board: determine that it is unobstructed, there is no waterlogging, and there is no siltation;

[0045] The above state ③ - the waterlogging detection sensor head and the silt detection sensor head 2 detect the "no water" and "water" signals through the control circuit board, respectively: determine that there is no waterlogging, but there is siltation;

[0046] The above case ① changes to the above state ② after a period of time: determine that the waterlogging subsides and there is no siltation;

[0047] The above case ① changes to the above state ③ after a period of time: determine that there is siltation after waterlogging;

[0048] The above case ② changes to the above state ① or ③ after a period of time: determine that there is waterlogging.

[0049] The device A transmits the above determination results to the man-machine interaction device.

[0050] After the implementation of the embodiment, the waterlogging and siltation of the monitored point can be automatically monitored by the device A, and the result can be obtained through the man-machine interaction device of the device A without manually opening the manhole cover, so as to greatly reduce the labor intensity, improve the work efficiency, eliminate the missed detection and wrong detection and improve the reliability.

[0051] Embodiment 2 - Waterlogging and siltation detection device with protective cover and interactive triggering function

[0052] As shown in Figure 2 , the waterlogging and siltation detection device B with the protective cover and the interactive triggering function is composed of a shell 1, a silt detection sensor head 2, a water accumulation detection sensor head 3, a control circuit board (not shown) installed in the shell 1, a man-machine interaction device (not shown due to angle reasons), a power supply (not shown) and the like. Among them: the shell 1 is a doctor's cap type, the upper part is a shell cap 11, and the lower part is a cylindrical shell body 12; the silt detection sensor head 2 and the water accumulation detection sensor head 3 are sealingly installed at the lower end of the shell body 12 and protrude from the shell body 12.

[0053] By comparison Figure 1 , Figure 2 , it can be seen that the device B of the embodiment is based on the device A of the embodiment 1, and a reversible protective cover 15 is arranged above the shell cap 11. The protective cover 15 is provided with a triggering column 16, and the corresponding position of the shell cap 11 is provided with a triggering area 17. The triggering area is a waterproof structure, and the lower part is provided with a triggering element (not shown) electrically connected with the control circuit board (not shown). When the protective cover 15 is buckled onto the shell cap 11, the triggering element can send a triggering signal to the control circuit board, so that the control circuit board enters the working state from the dormant state, and at the same time, the detection result is output to the man-machine interaction device (not shown). 18 in the figure is a transparent viewing window, and the detection result is displayed in the window. After a period of time, or after the protective cover 15 is buckled, the control circuit board enters the dormant state again, so as to greatly save the power consumption.

[0054] In the embodiment, ① the triggering column 16 is a rigid column, and the corresponding triggering area 17 is a flexible rubber, which is sealingly installed on the upper end face of the shell body 12. The lower part is provided with a button and a switch (not shown). When the protective cover 15 is buckled, the triggering column 16 extrudes the triggering area 17, triggers the button and the switch below, and makes them in the pressed state. When the protective cover 15 is opened, the state of the button and the switch changes, thereby forming a triggering action; ② the triggering column 16 is a permanent magnet; and the corresponding triggering area 17 is made of a non-magnetic material, and the lower part is provided with a magnetic sensitive element (including but not limited to a Hall element, a reed switch and the like). When the protective cover 15 is buckled, the magnetism of the triggering column 16 makes the magnetic sensitive element in the magnetic field. When the protective cover 15 is opened, the working state of the magnetic sensitive element changes, thereby forming a triggering action.

[0055] In operation, the protective cover 15 can be opened when reading the detection result, and the control circuit board is triggered to start the detection work, output the detection result, and delay for a period of time, or the protective cover 15 is opened, and the control circuit board enters the power-saving sleep state.

[0056] As an alternative technical solution, a solar panel or other green power supply device can be added to the device to supply power to the device to solve the power consumption problem of the device.

[0057] After the embodiment is implemented, the following advantages are achieved:

[0058] The power consumption is small, the application of the built-in battery can be supported, and the cost is greatly reduced;

[0059] The service life is greatly prolonged.

[0060] Embodiment 3 - automatic detection system for waterlogging and siltation

[0061] As shown in Figure 3 In this embodiment, the automatic detection system for waterlogging and siltation is composed of a plurality of waterlogging and siltation detection devices (waterlogging and siltation detection device 1~waterlogging and siltation detection device n) and a host computer. Each waterlogging and siltation detection device and the host computer is provided with a wireless communication circuit, and the communication signal is transmitted and received in the air through the respective antennas. The host computer periodically or temporarily inspects the siltation condition of the section where each waterlogging and siltation detection device is located according to the setting, and performs statistics, alarm, etc.

[0062] The beneficial effects of the embodiment after implementation are:

[0063] The siltation condition of each monitoring section and key section in the area can be automatically monitored, and the condition statistics can be automatically formed according to the design, which facilitates the dredging scheduling;

[0064] According to the system statistics, the sections prone to siltation, blockage and flooding can be compared and found in time, and the optimization and reconstruction of the drainage and sewage systems can be arranged as a whole;

[0065] According to long-term monitoring, the monitoring of the reconstructed and unblocked sections can be identified and removed to save monitoring resources, and the sections prone to siltation, blockage and flooding can be implemented for key monitoring.
