Further, the width of the water storage cavity is smaller than that of the cable cavity. Through the setting that is less than the water storage chamber width, can further reduce the rainwater exposure area in the water storage chamber that has ponding, reduce the humidity in water storage chamber to reduce the humidity in cable chamber. The cable chamber with be provided with water conservancy diversion portion 12 between the retaining chamber, water conservancy diversion portion is for extending to the slope of retaining chamber side from the cable chamber side, can be convenient through water conservancy diversion portion with the rivers income retaining chamber of cable intracavity, prevents that cable chamber bottom from remaining to have ponding.
Further, the water leaking plate 50 is a straight plate, two side edges of the water leaking plate 50 are erected on the water storage cavity, and two sides of the water leaking plate 50 have a set height difference in the vertical direction.
Specifically, the upper ends of the left side surface and the right side surface of the water storage cavity are provided with steps, the two longer side edges of the water leakage plate are erected on the left step and the right step of the water storage cavity respectively, and the left step and the right step are set to be different heights at the moment, for example, the left step is higher than the right step, or the right step is higher than the left step, so that the straight plate-shaped water leakage plate is obliquely arranged. After the cable pit is put into use for a certain time, some solid debris can exist in the bottom surface, and the effect of the board that leaks through the slope and ponding flow and gravity makes solid debris pile up the one side of the board that leaks, avoids solid debris to shield the hole that leaks, leads to the unable smooth inflow of water in cable chamber retaining chamber, causes the unable problem that reduces cable chamber moisture.
Furthermore, the cross section of the water leakage plate 50 along the width direction is of an arch structure, and two sides of the water leakage plate 50 are erected on the water storage cavity. When the degree of depth of retaining chamber is not enough or other reasons lead to not being convenient for to set the step to have the difference in height about the retaining chamber, can set up the step at same height, set the interface of the board width direction that will leak into the arch this moment, the both sides that the board that leaks are piled up to solid debris through the effect of arched board that leaks and ponding flow and gravity that leak, also can avoid solid debris to shield the hole that leaks, the water that leads to the cable chamber can't flow into the retaining chamber smoothly, cause the problem of unable reduction cable chamber moisture.
Further, the dehumidifying device 40 includes a blade 43 and a heating member 44, the blade 43 is disposed above the heating member 44, and a dehumidifying layer 41 is disposed above the blade 43.
