DETAILED DESCRIPTION OF THE INVENTION

[0037] The following further describes the present invention with reference to specific embodiments in the drawings.

[0038] Refer to Figures 1 to 4, An intelligent waterproof cover, comprising a waterproof cover body 1. The waterproof cover body 1 is a conical structure with a smaller upper end and a larger lower end. The top of the waterproof cover body 1 is provided with a first sealing connection part 8 for sealing connection with a cable, and the bottom of the waterproof cover body 1 is provided with a second sealing connection part 9 for sealing connection with a pre-buried pipe. At the lower end of the inner cavity of the waterproof cover body 1, there are several sensor modules 2, that is, the sensor modules 2 are embedded at the widest inner diameter of the lower end of the waterproof cover body 1, which can reduce the interference generated when installing the intelligent waterproof cover on the cable. The several sensor modules 2 are sequentially connected to form an annular structure adapted to the inner wall of the waterproof cover body 1. The top of the sensor module 2 is provided with a camera 3 for collecting images inside the waterproof cover body 1 and of the cable. The top of the sensor module 2 is provided with a temperature and humidity probe 4 for collecting the temperature and humidity inside the waterproof cover body 1. Inside or outside the sensor module 2 near the waterproof cover, there is a water accumulation probe 5 for collecting the water accumulation situation inside the waterproof cover body 1. The meaning of installing the water accumulation probe 5 inside the module is to enclose the water accumulation probe 5 inside, and installing it outside means sticking it outside and directly touching the waterproof cover. As Figure 2 shown, the bottom of the sensor module 2 is provided with a water accumulation probe 5.

[0039] In one embodiment, only the top of one of the sensor modules 2 is provided with a temperature and humidity probe 4, and the tops of the other sensor modules 2 are not provided with temperature and humidity probes 4, which can reduce costs. The sensor module 2 provided with the temperature and humidity probe 4 can be used as the first sensor module 2 and as a data output end.

[0040] By sequentially connecting several sensor modules 2 to form an annular structure and embedding and installing them at the lower end of the inner cavity of the waterproof cover body 1, images, water accumulation situation, temperature and humidity inside the waterproof cover body 1 can be obtained at all angles, the failure of the waterproof cover can be detected in time, and the cause of the failure of the waterproof cover and the specific evolution process can be intuitively understood.

[0041] The sensor module 2 is made of a flexible material and has a certain elasticity, and can arbitrarily change its overall shape. For example, when applied to the waterproof cover body 1 of this embodiment, the shape of the sensor module 2 is an arc structure, which can be conveniently combined to adapt to different specifications of waterproof covers. And it has good anti-vibration and compressive resistance, ensuring the stability and durability of the sensor in a complex construction environment.

[0042] In one embodiment, adjacent two sensor modules 2 are signal-connected through a flexible cable. Adopting a flexible connection structure between modules can protect the sensor from being damaged by extrusion during construction and has better anti-vibration and compressive resistance.

[0043] In one embodiment, adjacent two sensor modules 2 are signal-connected through a data connector 6. Preferably, the data connector 6 is a USB connector or a Type-C connector, which is convenient to assemble and has good data transmission stability.

[0044] Of course, the data connector 6 can also be a DB plug or other forms of data transmission plugs.

[0045] The water accumulation probe 5 is a capacitance liquid level sensor. Specifically, an array of capacitance liquid level sensors is provided inside or outside the sensor module 2. For example, an array of capacitance liquid level sensors is provided at the bottom of the sensor module 2 in this embodiment. The size of a single capacitance liquid level sensor is 10mm * 10mm, and the distance between the capacitance electrodes is 0.3mm. It can effectively detect water droplets with a size of 0.2 square millimeters, and has a high detection accuracy. By setting an array of capacitance liquid level sensors in the circumferential range, the water accumulation situation and the earliest position where water accumulation occurs can be accurately detected, and the reasons for the failure of the waterproof cover and the specific evolution process can be more intuitively understood.

[0046] A positioning installation groove 7 for the sensor module 2 is provided at the lower end of the inner cavity of the waterproof cover body 1. That is, the sensor module 2 is embedded and installed in the positioning installation groove 7. The sensor module 2 is embedded and installed in the positioning installation groove 7 by glue bonding or interference fit, and the installation is simple and convenient. A pluggable wiring head 10 with a sealed connection is provided on the side wall of the waterproof cover body 1. The pluggable wiring head 10 is connected to the data interface of the first sensor module 2 through an output cable.

[0047] A construction method for an intelligent waterproof cover includes the following steps:

[0048] Step 1. Connect several sensor modules 2 in sequence to form a ring structure in the factory. After electrically connecting adjacent two sensor modules 2, install them at the lower end of the inner cavity of the waterproof cover body 1. Take the first sensor module 2 as the signal output end and connect the output cable. That is, the data interface of the first sensor module 2 is connected to the pluggable wiring head 10 through the output cable to manufacture the intelligent waterproof cover.

[0049] Step 2. Connect the output cable to a computer and a power supply. That is, the pluggable wiring head 10 is further connected to the computer and the power supply through the output cable. The power supply supplies power and data is sent and received through the computer for testing to ensure that the signals and electricity between adjacent two sensor modules 2 can be transmitted to each other.

[0050] Step 3. Install the intelligent waterproof cover on the upper end of the embedded pipe at the lower end of the cable. The cable and the embedded pipe are the same size as the cable and the embedded pipe used in the actual project to simulate the actual installation between the cable and the embedded pipe.

[0051] Step 4. Configure the parameters of each sensor module 2 using a computer, including the parameters of the camera 3, the temperature and humidity probe 4, and the water accumulation probe 5, so that each sensor module 2 can effectively collect images, water seepage conditions, temperature, and humidity inside the waterproof cover body 1.

[0052] Step 5. Remove the intelligent waterproof cover from the cable model and the embedded pipe model, and pack it to prevent extrusion and collision damage during transportation;

[0053] Step 6. Transport the packed intelligent waterproof cover to the site;

[0054] Step 7. Clean the parts of the cable and the embedded pipe where they are connected to the intelligent waterproof cover;

[0055] Step 8. Install the intelligent waterproof cover on the cable and the embedded pipe, and make the water accumulation probe 5 of the sensor module 2 close to the end of the embedded pipe. Seal the upper and lower ends of the intelligent waterproof cover to the cable and the embedded pipe respectively (the sealing connection uses existing technology and will not be elaborated here);

[0056] Step 9. Arrange collectors at the beam end (bridge), converge the output cable wires of each intelligent waterproof cover to the beam end and connect them to the collectors. That is, the collectors can collect the data of the intelligent waterproof covers of multiple cables, and collect and transmit the data to the remote workstation through the collectors.

[0057] The above is only the preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can be made, and these will not affect the implementation effect of the present invention and the practicality of the patent.
