Detailed Description

Hereinafter, preferred embodiments of a buried box system having a dehumidifying function according to the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 illustrates a side view of a buried box system 100 having a dehumidification function according to an embodiment of the present invention, and fig. 2 and 3 illustrate a perspective view and a top view of the buried box system 100, respectively, as viewed from arrows a-a and B in fig. 1. With reference to fig. 1-3, the inground box system 100 includes a top wall 101, a plurality of side walls 102 (e.g., four side walls 102), and a bottom wall 103 that bound an interior space of the inground box system 100. Fig. 1 to 3 also show, among other things, that the top wall of the underground cabinet system 100 comprises an openable and closable top cover 104, the top cover 104 being positioned, for example, in the center of the top wall 101, by means of which top cover 104 objects to be stored can be filled into or removed from the underground cabinet system 100 and through which equipment and cabling in the interior space of the underground cabinet system 100 can be observed and maintained.

Fig. 2 also shows that a number of wiring holes 105 are provided through the side wall 102 for routing equipment inside the inground enclosure system 100 to the external environment therethrough. The specific routing of the equipment inside the inground box system 100 to the external environment depends on the location of the placement of the various pieces of equipment and is not described in detail herein.

Referring to fig. 2, the underground cabinet system 100 according to the embodiment includes a humidity control apparatus 110 and a fresh air apparatus 130. The humidity control apparatus 110 includes a humidity sensor 111 and a heating module 112. The humidity sensor 111 is configured to sense the humidity of the air inside the inground box system 100. since the density of the humid air is less than the density of the dry air at the same temperature, it is advantageous for the humidity sensor 111 to be disposed in the upper portion of the interior space of the inground box system 100, i.e., near the top wall 101, because such an arrangement can make it more accurate to sense the humidity condition in the air.

In order to avoid the corrosion of the metal structural members and the failure of the electrical components inside the underground cabinet system 100 caused by the overhigh humidity of the air due to the condensation in the internal space of the underground cabinet system 100 under the condition of low external ambient temperature, the humidity control device 110 further comprises a heating module 112. When the humidity sensor 111 senses that the humidity of the air inside the underground box system 100 reaches a preset humidity threshold, the heating module 112 is triggered to start to operate, so as to heat the air inside the underground box system 100 to achieve the effect of reducing the humidity of the air. The humidity threshold may be preset and adjusted depending on the type of fill within the inground tank system 100. The heating module 112 is advantageously disposed in the lower portion of the interior of the inground box system 100, i.e., adjacent the bottom wall 103, because this arrangement allows air proximate the heating module 112 to be heated first, and then the heated air rises to promote warming and dehumidification of the air in the upper space, thereby allowing the air in the entire interior space to be rapidly heated. For example, it is schematically shown in fig. 2 and 5 that the heating module 112 is arranged inside the side wall 102 adjacent to the bottom wall 103.

The heating module 112 may employ conventional means for heating air, advantageously a PTC heating module, which has the advantages of power saving and relative safety.

A temperature sensor (not shown) may be further provided in the inground box system 100. The temperature sensor may be attached to the heating module 112 to sense the operating temperature of the heating module 112 and trigger the heating module 112 to stop heating if the operating temperature exceeds a preset temperature threshold, thereby further ensuring the safety of operation of the heating module 112.

Alternatively, the temperature sensor may be disposed at other locations in the interior space of the inground box system 100 and configured to sense the temperature of the air inside the inground box system 100. Also in this case, the heating module 112 is triggered to stop heating if the air temperature is sensed to exceed a preset temperature threshold. For example, a temperature sensor may be disposed near the humidity sensor 111.

When the humidity sensor 111 senses that the humidity of the air inside the underground box system 100 reaches a preset humidity threshold, in addition to triggering the heating module 112 to heat the air inside the underground box system 100, the fresh air device 130 is also triggered to be started, so as to reduce the humidity of the air inside the underground box system 100 through the circulation of the air inside the underground box system 100 and the air of the external environment.

Still referring to fig. 2, the fresh air device 130 includes a blower 131, an air inlet 132, and an air outlet 133. The fan 131 is advantageously attached to the top cover 104 by a mounting bracket 136 and is disposed in the inground box system 100 interior space below the top cover 104. Since the buried box system 100 is buried in the ground during use with its side walls 102 and bottom wall 103, the air inlet opening 132 and the air outlet opening 133 of the fresh air device 130 are advantageously provided on the top wall 101 or the top cover 104 to communicate the internal space of the buried box system 100 with the external environment.

Fig. 2 shows that the air outlet 133 is provided on the top cover 104 to the outside space, while the air inlet 132 is provided on the top wall 101 adjacent to the side wall 102. Locating the air inlet 132 as far away from the air outlet 133 as possible is advantageous because this arrangement may increase the path of air circulation inside the inground box system 100, and thus the exchange of air inside the inground box system 100 with the outside ambient air. The air intakes 132 are closed during normal operation of the inground box system 100 but can be opened if desired. Specifically, the intake vent 132 is provided with an intake vent cover 134 that opens and closes the intake vent 132, and an actuator 135 is connected between the intake vent cover 134 and a wall of the underground cabinet system 100, for example, an inner side of a side wall, whereby the movement of the intake vent cover 134 is controlled by the movement of the actuator 135 to open and close the intake vent 132. The actuator 135 is shown in fig. 2 in the form of a telescoping rod, but it could be other actuators as well.

When the humidity sensor 111 senses that the air humidity inside the underground box system 100 reaches a preset humidity threshold, the fan 131 of the fresh air device 130 is triggered to start, so that the air inside the underground box system 100 is pumped to the external environment through the air outlet 133, and therefore the air humidity inside the underground box system 100 is further reduced.

Before the blower 131 is started, a determination of the opening state of the intake vent 132 is advantageously made, which is done by an infrared sensor (not shown in the figures) arranged in the vicinity of the intake vent 132, for example in the external environment on the top wall 101. Since the opening of the air inlet 132 requires the actuator 135 to actuate the air inlet cover 134 to open to the external environment, in the case that the underground box system 100 is buried in the ground, there may be a case that an interfering object exists outside the air inlet cover 134 and the air inlet cover 134 cannot be normally opened to the external environment, and if the actuator 135 is triggered to actuate the air inlet cover 134 to open to the external environment once the blower 131 is started, the air inlet cover 134 may not be normally opened or even be forcibly opened, which may cause damage to the air inlet cover 134 or the actuator 135 or an external object.

Sensing the ambient environment of the intake vent 132 with an infrared sensor before opening the intake vent 132 to determine whether the intake vent 132 can be opened properly avoids the potential risk of damaging the intake vent cover 134 or the actuator 135 or foreign objects described above. If it is determined by the infrared sensor that the surroundings of the intake vent 132 are not interfering objects and can be opened normally, the trigger actuator 135 actuates the intake vent cover 134 to open to the outside environment. In this case, the start of the blower 131 causes the air in the external environment to flow into the underground box system 100 through the air inlet 132, and the air in the underground box system 100 flows into the external environment through the air outlet 133, so that the humidity of the air in the underground box system 100 is reduced by the exchange of the internal air and the external air.

On the other hand, if it is determined by the infrared sensor that there is an interfering object around the air inlet 132 and the air inlet cannot be opened normally, the actuator 135 is not triggered to actuate the air inlet cover 134 to open to the outside environment. In this case, the activation of the fan 131 still causes the internal air of the underground cabinet system 100 to flow into the external environment through the air outlet 133, thereby reducing the air humidity inside the underground cabinet system 100 to some extent, but this case has a lower air circulation rate and a relatively lower air humidity reduction rate inside the underground cabinet system 100 compared to the case where the air inlet 132 is opened.

Advantageously, the fan 131 has at least two blowing intensities. The blowing intensity of the fan 131 when the fresh air device 130 is started is determined according to one of the following factors or a combination thereof: the size of the inground box actually used, the sensed humidity level of the air inside the inground box system 100, and the open status of the air intake 132. Specifically, in the case where the size of the underground cabinet actually used is small, the sensed humidity value of the air inside the underground cabinet system 100 reaches the preset humidity threshold value but exceeds the threshold value by a small amount, and the air inlet 132 can be normally opened, the fan 131 may be set to adopt a low blowing intensity. Conversely, in the case that the size of the underground cabinet actually used is large, the sensed humidity value of the air inside the underground cabinet system 100 exceeds the preset humidity threshold value by a large margin, and the air inlet 132 cannot be normally opened, the fan 131 may be set to adopt a high blowing intensity, thereby increasing the rate of reducing the humidity of the air inside the underground cabinet system 100. Depending on the actual requirements, the fan 131 may have three, four or even more different blowing strengths.

In addition, although only one humidity sensor 111 and one heating module 112 are shown in each drawing, more than one humidity sensor 111 and more than one heating module 112 may be provided depending on factors such as the size of the buried box actually, the arrangement of the fillers inside the buried box, and the like. Specifically, two or more humidity sensors 111 and two or more heating modules 112 may each be disposed at different locations inside the inground box system 100, and the activation of at least one heating module 112 and the fresh air device 130 is triggered as long as one of the humidity sensors 111 senses that the air humidity inside the inground box system 100 reaches a predetermined humidity threshold.

Also, more than one temperature sensor may be provided. Specifically, one temperature sensor may be provided at the heating module 112 to sense the temperature of the heating module 112, while another temperature sensor is provided at another location to sense the temperature of the air inside the inground box system 100, and the heating module 112 is deactivated whenever the temperature sensed by one of the temperature sensors reaches its preset temperature threshold.

Fig. 4 and 5 respectively show perspective views of the internal configuration of the inground box system 100 as seen from different perspectives with one side wall of the inground box system 100 removed. Fig. 4 shows more details of the fan 131. In this embodiment, the fan 131 is attached to the top cover 101 by a mounting bracket 136. At least one humidity sensor 111 and at least one temperature sensor may also be attached to the top cover 101 by the mounting bracket 136. This arrangement simplifies the wiring design on the one hand and facilitates the observation and maintenance of the internal equipment on the other hand, since the top cover 101 can be easily opened from the outside.

The operation flow of the buried box system 100 with dehumidification function according to the present invention is described as follows:

first, the system 100 is powered on, and at least one humidity sensor 111 senses the humidity of the air inside the inground box system 100;

if the humidity of the air inside the underground box system 100 sensed by the at least one humidity sensor 111 reaches a preset humidity threshold, triggering the heating module 112 to operate and triggering the infrared sensor to detect the air inlet 132 to determine whether the air inlet 132 can be normally opened, and heating the air inside the underground box system 100 by the heating module 112 until the temperature sensed by the at least one temperature sensor reaches the preset temperature threshold, stopping the operation of the heating module 112;

if it is determined that the air inlet 132 can be opened normally, the trigger actuator 135 actuates the air inlet cover 134 to open to the outside environment to open the air inlet 132, and simultaneously the blower 131 is turned on at the determined blowing intensity, so that the air inside the underground box system 100 is circulated with the outside environment air under the action of the blower 131 to further reduce the air humidity inside the underground box system 100;

if it is determined that the air inlet 132 cannot be opened normally, the actuator 135 is not triggered to actuate the air inlet cover 134 to open to the outside environment, the air inlet 132 remains closed, and the blower 131 is turned on at the determined blowing intensity, so that the inside air of the buried box system 100 is circulated to the outside environment through the air outlet 133 under the action of the blower 131, so as to further reduce the air humidity inside the buried box system 100.

In conclusion, utilize the utility model discloses a bury case system with dehumidification function buries the inside air humidity of case system and senses burying under the circumstances of case system circular telegram with burying in real time, when sensing when air humidity reaches preset's humidity threshold value, can reduce air humidity's processing automatically, from this constantly keep burying case system internal environment dry with burying, has reduced and has buried the risk that case system internal metal structure corrosion and electrical component became invalid.
