[0039] like Figures 1 to 9As shown, an embodiment of the utility model provides a distributed DC power supply device, including a cabinet 1, both sides of the cabinet 1 are provided with mounting holes 2, both sides of the cabinet 1 are fixedly connected with heat dissipation boxes 3, the heat dissipation boxes 3 are installed on one side of the mounting holes 2, a plurality of heat dissipation holes are provided on the heat dissipation boxes 3, a fixing sleeve 4 is fixedly connected to one side of the top of the heat dissipation boxes 3, a placement hole 6 is provided on the top of the heat dissipation boxes 3, a sealing door 5 is rotatably connected to the inner wall of the placement hole 6, one end of the sealing door 5 is a tilted structure, a plurality of anti-slip strips are fixedly connected to the bottom of the tilted structure, a mounting sleeve 10 is fixedly connected to one side of the top of the sealing door 5, and a positioning groove 11 is provided on the mounting sleeve 10 The limiting groove 12 and the positioning groove 11 are connected to the limiting groove 12. A limiting spring 13 is fixedly connected to one side of the inner wall of the mounting sleeve 10. One end of the limiting spring 13 is fixedly connected to a clamping rod 14. The clamping rod 14 is slidably connected to the inner wall of the positioning groove 11. The end of the clamping rod 14 away from the limiting spring 13 is inclined. The direction of the inclined surface points upward. A push rod 15 is fixedly connected to the top of the clamping rod 14. The push rod 15 is an inverted L-shaped structure. A group of limiting plates 8 are fixedly connected to the inner wall of the heat dissipation box 3; a drying component, which is used to absorb moisture in the humid air entering from the heat dissipation hole, and the drying component is connected to the limiting plate 8.

[0040] By setting the drying component in the heat dissipation box 3, when installing the distributed DC power supply device, the distributed DC power supply device can be installed in a circuit device for power supply or distribution. At this time, when the humid air enters the cabinet 1 along the heat dissipation holes opened on the heat dissipation box 3, the moisture in the air will be absorbed by the drying component to prevent the humid air from entering the cabinet 1 and causing damage to the electrical components inside the cabinet 1. The drying component is set in the heat dissipation box 3. In normal state, the clamping rod 14 is clamped with the fixing sleeve 4. When replacement is required, the sealing door 5 can be rotated to open, and the push rod 15 is pressed horizontally to drive the clamping rod 14 to slide in the positioning groove 11, so that the clamping rod 14 leaves the fixing sleeve 4, and the fixing sleeve 4 no longer has a limiting effect on the clamping rod 14. The push rod 15 is an inverted L-shaped structure, which increases the friction between the operator's hand and the operator's hand, making it easy to press the push rod 15 horizontally. At this time, the operator can place another finger on the tilting structure at one end of the sealing door 5, and the sealing door 5 can be rotated to open. A plurality of anti-slip strips are fixedly connected to the bottom of the tilting structure, which increases the contact between the operator's fingers and the sealing The friction force at one end of the door 5 makes it easy for the operator to rotate the sealed door 5 to open, and the drying component located in the middle of a set of limit plates 8 can be directly taken out and replaced, so that when replacing the drying component, the operation is simple, and there is no need to dismantle the cabinet 1 for replacement. In addition, the size of the opened sealed door 5 is small, and the probability of dust and moisture in the air entering the cabinet 1 through the placement hole 6 is reduced, thereby reducing the probability of damage to the electrical components in the cabinet 1, and prolonging the service life of the distributed DC power supply device in the power supply or distribution circuit device. After completion, the sealing door 5 can be rotated to close the sealing door 5. When closing the sealing door 5, the sealing door 5 is rotated until the bottom of the clamping rod 14 contacts the top of the fixed sleeve 4. The end of the clamping rod 14 away from the limit spring 13 is beveled, and the direction of the bevel points upward, so that when the sealing door 5 continues to be rotated, the clamping rod 14 moves in the positioning groove 11, and the limit spring 13 is in a compressed state. After the sealing door 5 is completely restored to its original position, the clamping rod 14 is restored to its original position and connected with the fixed sleeve 4 under the action of the elastic force of the limit spring 13, thereby realizing the replacement of the drying component.

[0041] like Figures 2 to 6 , Fig. 9As shown, the drying component includes a mounting frame 9 which is slidably connected to the inner wall of a group of limit plates 8, a plurality of mounting plates 18 are fixedly connected to the mounting frame 9, a sleeve rod 19 is fixedly connected to one side of each mounting plate 18, the sleeve rod 19 is a T-shaped structure, a card slot 20 is provided on the sleeve rod 19, a plurality of clamping plates 21 are fixedly connected to the mounting frame 9, one end of the clamping plate 21 is fixedly connected to the mounting frame 9, the material of the clamping plate 21 is a plastic metal material, a positioning rod 22 is fixedly connected to one side of the clamping plate 21, the positioning rod 22 is a T-shaped structure, the positioning rod 22 is plugged into the card slot 20, a taking groove 23 and a placing groove 24 are provided on both sides of the top of the mounting frame 9, the taking groove 23 and the placing groove 24 are connected, a drying bag 16 is provided on the inner wall of the mounting frame 9, a plurality of positioning holes 17 are provided on the drying bag 16, and the positioning holes 17 are sleeved on the sleeve rod 19.

[0042] When the drying assembly is replaced, the drying bag 16 in the drying assembly can be replaced, so that the mounting frame 9 can be reused. When replacing the drying bag 16, a plurality of snap-in plates 21 can be pried open. The material of the snap-in plates 21 is a plastic metal material. The snap-in plates 21 are pried open so that the positioning rod 22 fixedly connected to one side of the snap-in plates 21 leaves the card slot 20, and the limit of the positioning rod 22 by the sleeve rod 19 is released. The positioning rod 22 has a T-shaped structure for easy insertion into the card slot 20, and the sleeve rod 19 has a T-shaped structure. The positioning hole 17 provided on the drying bag 16 is sleeved on the sleeve rod 19, so that the positioning rod 22 forms a limit effect on the positioning hole 17 after being inserted into the card slot 20, so as to prevent the drying bag 16 from moving during use and improve the stability of the drying bag 16 during use. After the snap-in plates 21 are pried open so that the positioning rod 22 fixedly connected to one side of the snap-in plates 21 leaves the card slot 20, , the drying bag 16 can be removed from the sleeve rod 19, the positioning hole 17 opened on the new drying bag 16 can be re-set on the sleeve rod 19, and the clamping plate 21 can be bent in the opposite direction so that the positioning rod 22 fixed on one side of the clamping plate 21 is plugged into the clamping groove 20 opened on the sleeve rod 19, so as to realize the replacement of the drying bag 16. The mounting frame 9 with the replaced drying bag 16 can be reinstalled in the heat dissipation box 3, and a group of limiting plates 8 can effectively limit the mounting frame 9. Specifically, rectangular chamfers are provided on both sides of the bottom of the mounting frame 9, which is convenient for inserting the mounting frame 9 along the placement hole 6. The taking grooves 23 and the placement grooves 24 provided on both sides of the top of the mounting frame 9 are convenient for the operator to place his hands to take the mounting frame 9, so that in the process of replacing the drying component, only the drying bag 16 needs to be replaced, and the drying bag 16 is easy to disassemble and install, and the mounting frame 9 can be reused, thereby reducing the production cost.

[0043] like Figure 3 and Figure 8 As shown, a pair of sealing pads 7 are fixedly connected to the inner wall of the placement hole 6. The sealing pads 7 are trapezoidal in structure, and a weakened groove is provided at the bottom of the trapezoidal structure. The bottom of the sealing door 5 is adapted to the sealing pads 7.

[0044] The sealing gasket 7 is provided in a trapezoidal structure, and a weakened groove is provided at the bottom of the trapezoidal structure. The top of the sealing gasket 7 is matched with the bottom of the sealing door 5, thereby improving the sealing performance after the sealing door 5 is closed, and further reducing the possibility of moisture in the air entering the cabinet 1. The sealing gasket 7 is an elastic structure. When the drying bag 16 absorbs moisture in the air and needs to be replaced, when the mounting frame 9 and the drying bag 16 are taken out, the provided sealing gasket 7 can be elastically deformed without affecting the removal of the drying bag 16.

[0045] The working principle of the technical solution provided by the utility model is as follows:

[0046] When in use, the distributed DC power supply device can be installed in a circuit device for power supply or distribution. At this time, when humid air enters the cabinet 1 along the heat dissipation holes opened on the heat dissipation box 3, it will pass through the drying component to absorb moisture in the air. In normal state, the clamping rod 14 is clamped with the fixing sleeve 4. When replacing the drying component, the sealing door 5 can be rotated to open, and the push rod 15 is pressed horizontally to drive the clamping rod 14 to slide in the positioning groove 11, so that the clamping rod 14 leaves the fixing sleeve 4, and the fixing sleeve 4 no longer has a limiting effect on the clamping rod 14. At this time, the operator can place another finger on the tilting structure at one end of the sealing door 5, and the sealing door 5 can be rotated to open, and the drying component located in the middle of a group of limiting plates 8 can be directly taken out and replaced. After the drying component is taken out, the drying bag 16 can be replaced. Specifically, a plurality of clamping plates 21 are pried open. The material of the clamping plate 21 is a plastic metal material. The clamping plate 21 is pried open so that the positioning rod 22 fixedly connected to one side of the clamping plate 21 leaves the clamping groove 20, releasing the sleeve rod 19 from the positioning The rod 22 is limited, the drying bag 16 is removed from the sleeve rod 19, the positioning hole 17 opened on the new drying bag 16 is re-set on the sleeve rod 19, and the clamping plate 21 is reversely bent so that the positioning rod 22 fixed on one side of the clamping plate 21 is plugged into the clamping groove 20 opened on the sleeve rod 19 to realize the replacement of the drying bag 16. The mounting frame 9 with the replaced drying bag 16 can be reinstalled in the heat dissipation box 3, and a set of limiting plates 8 can effectively limit the mounting frame 9. At this time, the sealing door 5 can be rotated to close the sealing door 5. When closing the sealing door 5, the sealing door 5 is rotated until the bottom of the clamping rod 14 contacts the top of the fixing sleeve 4. The bottom of the clamping rod 14 is inclined toward the end of the clamping rod 14 away from the limit spring 13, and the direction of the inclined surface points upward, so that when the sealing door 5 continues to be rotated, the clamping rod 14 moves in the positioning groove 11, and the limit spring 13 is in a compressed state. After the sealing door 5 is completely restored to its original position, the clamping rod 14 is restored to its original position and connected with the fixing sleeve 4 under the action of the elastic force of the limit spring 13, thereby realizing the replacement of the drying component.
