Floor 3 is provided with protective structure down in the position department that corresponds with the mouth of blowing of blast apparatus 4 in cable intermediate layer region 1.3, it is including being fixed in the lower protective bracket 7 of floor 3 below and setting up filter equipment 9 (by the wire net with be fixed in the filter pulp on the wire net and constitute) in lower protective bracket 7, floor 3 is provided with hollow out construction (seted up fretwork hole 10 on the bottom plate 3) in the position department that corresponds with filter equipment 9's top, lower protective bracket 7 is located the wind path of blast apparatus 4 in cable intermediate layer region 1.3, the bottom of lower protective bracket 7 is seted up and is made the wind gap 8 that bloies of blast apparatus 4 in cable intermediate layer region 1.3 pass through.

As shown in fig. 9, the monitoring device includes a temperature and humidity sensor 5; the left side, the middle part and the right side of the equipment region 1.2 are respectively provided with a temperature and humidity sensor 5, the left side, the middle part and the right side of the cabin wiring region 1.1 are respectively provided with a temperature and humidity sensor 5, and the left side, the middle part and the right side of the cable interlayer region 1.3 are respectively provided with a temperature and humidity sensor 5. Two blowing devices 4 which respectively convey air outside the secondary cabin 1 to the equipment area 1.2 and convey air inside the equipment area 1.2 to the outside of the secondary cabin 1 are arranged in the equipment area 1.2, and a temperature and humidity sensor 5 is arranged at an air outlet of the blowing device 4 which conveys air outside the secondary cabin 1 to the equipment area 1.2.

In the invention, the air conditioners 13 and the fans in the equipment area 1.2 are arranged on the short walls at two ends of the secondary cabin, the current general design form is kept, and the equipment area 1.2 adopts a left-in right-out blowing design in the scheme. Fans are arranged at the two ends and the middle of the ceiling 2, the fans at the two ends blow upwards, and the fan in the middle blows downwards. The fan opening is of a self-hanging shutter structure, when the fan does not work, the vent opening can be automatically closed (when the fan does not work, due to the dead weight of the shutter 6, the blades droop and are in a closed state, when the fan is started, the blades are pushed away by wind pressure, air can circulate through the shutter 6, the flow is larger, the opening of the shutter 6 is larger until the opening of the shutter 6 reaches the maximum, when the fan is closed again, the blades of the shutter 6 restore to the drooping state, the shutter 6 can also achieve the reset effect by adopting a structure that a spring is arranged at the rotating shaft of the blades, floor tiles at four corners of the floor 3 are designed into steel plates with hollowed-out patterns (the hollowed-out patterns can be made into specific patterns or logo patterns to increase the aesthetic feeling), the fan is designed and installed in a cable clamping layer area 1.3, the fan on the left side blows downwards, and the fan on the right side blows upwards.

Based on the secondary cabin structure, the temperature and humidity sensor 5 is additionally arranged and reasonably distributed. At least three temperature and humidity sensors 5 are respectively arranged in the upper, middle and lower three-layer space of the secondary cabin, so that the environmental conditions of all places in the cabin can be known in real time without dead angles. A temperature and humidity sensor 5 is arranged at an air inlet of the bulkhead air intake fan. In fig. 9, the recommended placement position of the temperature/humidity sensor 5 is shown. When the temperature and humidity of the cabin wiring area 1.1 and the cable interlayer area 1.3 are normal, the internal fan does not work, and only the air conditioner works. The cabin air circulation is shown in figure 2. When the temperature and humidity sensor 5 detects that the temperature and humidity of the cabin wiring area 1.1 or the cable interlayer area 1.3 are abnormal, the fan at the corresponding position is started. When the air conditioner 13 and all the internal fans are activated, the wind direction of the in-cabin facilities is circulated as shown in fig. 8.

The circulation of the secondary cabin is divided into an internal circulation mode and an external circulation mode, and the control logic is also explained according to the two conditions. The control strategy in this section is only an explanatory principle, and a secondary cabin environment control strategy can be flexibly formulated according to engineering conditions in practical application.

Internal circulation: the internal environment control requirement of the secondary equipment cabin is 18-25 ℃ (when people exist). When the temperature in the cabin is lower than 18 ℃, starting a heating function; and when the temperature in the cabin is higher than 25 ℃, starting the refrigeration function. When the humidity of the cabin top and the cabin bottom is abnormal (obviously higher than the equipment area 1.2), the fans of the cabin top and the cabin bottom are started. The fan in the cabin can be kept fully open, and the temperature balance in the secondary cabin is promoted. When the temperature and humidity environment conditions of the equipment area 1.2 are not good (for example, the humidity is too high), the air ports of the ceiling 2 and the floor 3 can be closed, and moisture and the like can be prevented from entering the top space or the bottom space. The temperature of the cabin top and the cabin bottom is allowed to be higher or lower than the temperature of the equipment area, and the buffer layer is used as a buffer layer for heat conduction inside and outside the cabin, so that the internal fan can be turned off under the normal condition of humidity, and the energy is saved.

External circulation: the external circulation is generally used when fresh air is needed in the cabin, and at the moment, only the fans at the two cabin walls are started. The fans of the ceiling 2 and the floor 3 are switched on only when the outside air quality is good.

The secondary cabin structure designed by the invention does not influence the arrangement or layout of other heating and ventilating facilities, such as wall heating, floor heating, dehumidifying devices, distributed heaters in a cabinet (frame) and the like, necessary equipment facilities and sensors can be added on the basis of the secondary cabin structure, and a control strategy can be flexibly adjusted according to actual engineering and temperature and humidity control requirements.

The environment monitoring and adjusting system for the whole space in the prefabricated cabin of the secondary equipment, which is designed by the invention, makes up the defects of the existing environment control scheme of the secondary cabin, can monitor the temperature and humidity conditions of the top space and the bottom space, can adjust the air circulation of the environment through the air blowing device 4, can monitor and control the space environment in the whole secondary cabin 1, and ensures that the environment states of all parts in the secondary cabin 1 are known and controllable. The condensation of the cabin top and the cabin bottom is avoided, the problems encountered in the actual engineering such as overhigh temperature of the cable interlayer are solved, and the cable clamp has good market application value.
