DETAILED DESCRIPTION

[0028] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] A placement plate 207 is slidably connected to the inner wall of the installation cavity 202 . The surface of the placement plate 207 is provided with evenly distributed through holes. A first spring 208 is fixedly connected between the bottom of the placement plate 207 and the inner wall of the installation cavity 202 .

[0033] like Figure 1-Figure 8 As shown, the desiccant component 21 includes a cover body 2101 threadedly connected to the inner side of the connecting ring 206, a storage shell 2105 is arranged at the bottom of the cover body 2101, the lower end of the storage shell 2105 extends to the interior of the mounting cavity 202 and contacts the surface of the placement plate 207, the surface of the storage shell 2105 is provided with evenly distributed connecting holes, the top of the storage shell 2105 is fixedly connected to the mounting ring 2106, the outer side of the mounting ring 2106 is fixedly connected with two symmetrically distributed blocks 2107, and the bottom of the cover body 2101 is provided with a connecting groove 2104 corresponding to the mounting ring 2106.

[0034] The inner wall of the connecting groove 2104 is provided with a sliding groove 2102 corresponding to the clamping block 2107, the inner wall of the sliding groove 2102 is provided with a clamping groove 2103, and the inner wall of the clamping groove 2103 is provided with an installation groove. The sliding groove 2102, the clamping groove 2103 and the installation groove are approximately distributed in an inverted "J" shape.

[0035] A liquid storage shell 2110 is fixedly connected to the inner wall of the mounting groove, an extrusion plate 2111 is slidably connected to the inner wall of the liquid storage shell 2110, hydraulic oil is filled between the bottom of the extrusion plate 2111 and the inner wall of the liquid storage shell 2110, an extrusion rod is fixedly connected to the top of the extrusion plate 2111, the upper end of the extrusion rod passes through the liquid storage shell 2110 and is fixedly connected to a pressure plate 2113 slidably connected to the inner wall of the mounting groove, and a second spring 2112 is fixedly connected between the bottom of the pressure plate 2113 and the surface of the liquid storage shell 2110.

[0036] Two symmetrically distributed adjusting cavities 2108 are provided inside the cover body 2101, and an adjusting rod 2115 is slidably connected to the inner wall of the adjusting cavity 2108. The upper end of the adjusting rod 2115 passes through the adjusting cavity 2108 and is fixedly connected to an indicating rod 2114 slidably connected to the inner wall of the cover body 2101. The top surface of the indicating rod 2114 is flush with the top surface of the cover body 2101. The inner bottom wall of the adjusting cavity 2108 is connected to a conduit 2109, and the other end of the conduit 2109 is connected to the liquid storage shell 2110.

[0037] The interior of the storage shell 2105 is used to place the desiccant. After the desiccant is placed, the storage shell 2105 is inserted into the interior of the slide groove 2102 of the cover body 2101 through the block 2107 on the mounting ring 2106 until it moves to the inner top wall of the slide groove 2102 and is blocked. The cover body 2101 is rotated to make the block 2107 slide into the interior of the slot 2103, thereby completing the connection between the storage shell 2105 and the cover body 2101. The operation is simple and convenient for replacing the desiccant. After moving into place, the bottom of the block 2107 is in contact with the top surface of the pressure plate 2113. During use, as the moisture is absorbed, As the pressure of the desiccant increases, the weight of the desiccant will gradually increase, so that it can drive the block 2107 to press down the pressure plate 2113 through the action of gravity, drive the pressure plate 2113 to compress the second spring 2112 and drive the pressure rod to insert into the liquid storage shell 2110. In this process, the hydraulic oil stored in the liquid storage shell 2110 can be squeezed, so that the hydraulic oil is introduced into the adjusting chamber 2108 through the conduit 2109, thereby pushing the adjusting rod 2115 to move up and driving the indicator rod 2114 to extend. The staff can replace the desiccant according to the extension of the indicator rod 2114 to avoid the desiccant adsorption saturation affecting the subsequent absorption effect.

[0038] By setting up multiple installation cavities 202 and connecting channels 204, the gas introduced into the shell 1 can be subjected to multiple drying treatments, which effectively reduces the occurrence of short circuits caused by underground moisture entering the shell 1 during the heat dissipation of the electronic control device inside the shell 1, thereby improving safety.

[0039] like Figure 1-Figure 8 As shown, the air guide component 22 includes a connecting shell 2201 fixedly connected to one side of the mounting shell 201, and a side of the connecting shell 2201 away from the mounting shell 201 is provided with evenly distributed ventilation grooves 2202, and a filter 2203 for shielding the ventilation grooves 2202 is embedded in the surface of the connecting shell 2201, a fan 2210 is arranged inside the connecting shell 2201, and a guide block 2207 is arranged inside the ventilation groove 2202.

[0040] The inner wall of the connecting shell 2201 is rotatably connected to a rotating shaft, and the surface of the rotating shaft is fixedly connected to evenly distributed driving blades 2208, one end of the rotating shaft passes through the connecting shell 2201 and is fixedly connected to a transmission mechanism 2209, a reciprocating screw 2206 is provided on the surface of the connecting shell 2201, and the surface of the connecting shell 2201 is rotatably connected to the reciprocating screw 2206, one end of the reciprocating screw 2206 is fixedly connected to the surface of the transmission mechanism 2209, a connecting plate 2205 is provided on the surface of the reciprocating screw 2206, and a cleaning block is provided on the surface of the connecting plate 2205.

[0041] A guide rod 2204 is fixedly connected to the surface of the connecting shell 2201 , and the other end of the connecting plate 2205 is slidably connected to the surface of the guide rod 2204 .

[0042] The specific fan 2210 is a plasma fan 2210, which can guide the airflow into the interior of the connecting cavity 203 and introduce it into the interior of the outer shell 1 after being dried by the desiccant component 21, thereby dissipating heat and cooling the electronic control device inside the outer shell 1, reducing the impact of accumulated heat on it. Since the fan 2210 is a plasma fan 2210, it can reduce the interference of static electricity on the electronic control device inside the outer shell 1.

[0043] In addition, the airflow can be guided by the guide block 2207 during the process of passing through the filter 2203 and the ventilation slot 2202, so as to push the driving blade 2208 to drive the rotating shaft to rotate. The transmission mechanism 2209 is a relatively mature component in the existing technology application, and is composed of two transmission wheels and a transmission belt. By driving one of the transmission wheels to rotate through the rotating shaft, the other transmission wheel can be driven by the transmission belt to drive the reciprocating screw rod 2206 to rotate. With the cooperation of the guide rod 2204, the connecting plate 2205 can be driven to move back and forth, thereby driving the cleaning block to clean the surface of the filter 2203, so that it can maintain a good filtering effect and avoid clogging by dust and impurities that affect the use of the filter 2203.

[0044] like Figure 1-Figure 8 As shown, the protective component 3 includes a protective shell 301 arranged on the surface of the control panel 101, a hinge 302 is arranged on the surface of the protective shell 301, a sealing gasket 304 located on the inner side of the protective shell 301 is arranged on the surface of the control panel 101, and a pull plate 303 is fixedly connected to the bottom of the protective shell 301.

[0045] Under the action of gravity, the hinge 302 of the protective shell 301 can cover the operating knob on the control panel 101, reducing the possibility of moisture adhering to the operating knob and causing electric shock when touched. The setting of the sealing gasket 304 can enhance the sealing effect with the protective shell 301 and prevent moisture from entering the interior of the protective shell 301 through the gap between the protective shell 301 and the control panel 101.

[0046] Working principle: the air guide component 22 can guide the airflow into the interior of the connecting cavity 203 and introduce it into the interior of the housing 1 after being dried by the moisture absorption component 21, thereby dissipating heat and cooling the electronic control device inside the housing 1 to reduce the influence of accumulated heat on it. During the use of the moisture absorption component 21, as the moisture absorption increases, the weight of the desiccant will gradually increase, so that it can drive the block 2107 to press down the pressure plate 2113 through the action of gravity, drive the pressure plate 2113 to compress the second spring 2112 and drive the pressure rod to insert into the interior of the liquid storage shell 2110. In this process, the hydraulic oil stored in the liquid storage shell 2110 can be squeezed, so that the hydraulic oil is introduced into the interior of the regulating cavity 2108 through the conduit 2109, thereby pushing the regulating rod 2115 to move up and driving the indicator rod 2114 to extend. The staff can replace the desiccant according to the extension of the indicator rod 2114 to avoid the desiccant adsorption saturation affecting the subsequent absorption effect.
