[0029] In the prior art, the power transmission line in the cable well is provided with a sheath circulating current online monitoring device, which generally adopts a current transformer (CT) to induce power, and the sheath circulating current online monitoring device is offline due to low load of the power transmission line and signal transmission problems. Specifically, due to small load of part of the line in the cable well, unstable induced current cannot provide sufficient power to the collector, and the collector is powered off for a long time, resulting in device offline. In addition, the signal transmitting device in the prior art is blocked by the cable cover plate 1, resulting in that the cable sheath circulating current online monitoring device cannot transmit signals, and the background display device is in an offline state.

[0030] The first embodiment of the utility model provides a cable well cover, the cable well cover is installed in the well mouth of cable well, as shown in Figure 1 and Figure 2 The cable well cover includes a cover plate 1, the cover plate 1 is provided with an energy storage battery 2, and the top of the cover plate 1 is provided with a solar cell panel 3. Specifically, the solar cell panel 3 is embedded on the top of the cable cover plate 1, the energy storage battery 2 is arranged in the lower part of the cover plate 1, the solar cell panel 3 directly converts light energy into electric energy through photoelectric effect or photochemical effect, and then stores the electric energy in the energy storage battery 2. The energy storage battery 2 is connected with the sheath circulating current online monitoring device for auxiliary power supply. The electric energy is obtained by combining solar power and induced power of the power transmission line, and the energy storage battery 2 can still supply power when the induced power is unstable, thereby avoiding the sheath circulating current online monitoring device offline.

[0031] Since the charge and discharge rate needs to consider the energy storage state (SOC) and deep discharge (DOD) of the energy storage battery 2, the energy storage battery 2 cannot meet all the DC load working voltage, the solar cell panel 3 and the energy storage battery 2 cannot be directly connected, and therefore the output voltage of the energy storage battery 2 needs to be converted by a DC-DC converter to increase the DC voltage or adjust the load working voltage, so as to realize the function of stable voltage output. Therefore, the solar cell panel 3 and the energy storage battery 2 are connected through a DC-DC converter to control the solar cell panel 3 to charge the energy storage battery 2.

[0032] The cover plate 1 is further provided with a communication module, the communication module includes a reinforced antenna embedded in the cover plate 1, the reinforced antenna includes a signal receiving antenna and a signal transmitting antenna, the signal transmitting antenna is used for transmitting signals in the cable well to other control units, and the signal receiving antenna is used for receiving signals of other control units. The communication module can realize signal transmission in the cable well. Wherein, the reinforced antenna is adopted to improve signal gain and realize stable signal transmission.

[0033] In addition, the reinforcing antenna is embedded in the cover plate 1, and the end of the signal transmitting antenna is led to the ground without affecting the ground passage, so that the signal transmitting antenna is not blocked by the cable cover plate 1, and the cable sheath circulation causes the online monitoring device to be unable to transmit signals.
