Description

Technical Field

[0001] The utility model relates to the technical field of switch cabinet dehumidification, in particular to a dust-proof mechanism and a switch cabinet. Background Art

[0002] A switch cabinet is a key power equipment installed in an outdoor environment, mainly used for power distribution, control, protection and monitoring. It has functions such as circuit breaking, overload protection, and isolating fault areas, ensuring stable operation under harsh weather conditions and guaranteeing the safety and reliable power supply of the power system.

[0003] Workers usually set up a chimney on the top of an outdoor switch cabinet to maintain air circulation for the purpose of removing moisture inside the switch cabinet. However, dust easily enters through the opening of the chimney, and fine dust particles enter the circuit board, causing a short circuit in the circuit and increasing the risk of equipment failure or damage. Summary of the Utility Model

[0004] The purpose of this part is to outline some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this part, as well as in the abstract and the title of the utility model of this application, to avoid obscuring the purpose of this part, the abstract, and the title of the utility model. However, such simplifications or omissions shall not be used to limit the scope of the utility model.

[0005] In view of the problem that dust enters from the chimney opening in the above or existing technology, and fine dust particles enter the circuit board, causing a short circuit in the circuit and increasing the risk of equipment failure or damage, the present utility model is proposed.

[0006] Therefore, the purpose of the present utility model is to provide a dust-proof mechanism.

[0007] To solve the above technical problems, the present utility model provides the following technical solution: A dust-proof mechanism includes,

[0008] A dust-blocking component, including a chimney, a dust-blocking member provided at the top of the chimney, and a cabinet body provided at the bottom of the chimney; wherein, a ventilation hole communicating with the chimney is opened on the cabinet body; wherein, an exhaust fan is provided at the top end of the chimney.

[0009] As a preferred scheme of the dust-proof mechanism of the present utility model, wherein: the dust-blocking member includes a protective cover slidably sleeved on the top of the chimney.

[0010] As a preferred scheme of the dust-proof mechanism of the present utility model, wherein: a rain shield is provided at the top of the protective cover.

[0011] As a preferred scheme of the dust-proof mechanism of the present utility model, wherein: a plurality of first sliding holes are opened on the protective cover and are evenly arranged in a circle around the axis of the protective cover.

[0012] As a preferred embodiment of the ash baffle mechanism of the present utility model, wherein: a fixing block slidably sleeved with the first sliding hole is arranged on the outer wall of the chimney.

[0013] As a preferred embodiment of the ash baffle mechanism of the present utility model, wherein: a plurality of cutting net pieces are arranged on one side of the fixing block close to the bottom end of the first sliding hole.

[0014] As a preferred embodiment of the ash baffle mechanism of the present utility model, wherein: the vertical projection area of the rain shield is larger than the vertical projection area of the protective cover.

[0015] The beneficial effects of the ash baffle mechanism of the present utility model are as follows: by providing a chimney and an ash baffle, it is avoided that the temperature inside the outdoor switch cabinet is lower than that outside the cabinet, resulting in the contact between the hot air inside the cabinet and the metal inner wall and the generation of condensation. It is prevented that as the temperature difference between the external environment and the temperature inside the cabinet is large, the condensation forms water droplets and flows onto the electronic equipment inside the cabinet, reducing the risk of short circuit of the electronic equipment.

[0016] In view of the fact that during the actual use process, there is also a risk problem that when manually opening the outdoor switch cabinet for dehumidification, after the rain comes, the worker forgets to close the door of the switch cabinet, resulting in rainwater entering the cabinet and wetting the electronic equipment, causing short circuit of the equipment.

[0017] To solve the above technical problems, the present utility model further provides the following technical solution: a switch cabinet, including,

[0018] A shielding assembly, including a rain receiving member and a guiding member arranged on the rain receiving member.

[0019] As a preferred embodiment of the switch cabinet of the present utility model, wherein: the guiding member includes a guiding shell, a second sliding hole is opened on the guiding shell, and a spring is arranged on the inner wall of the bottom of the guiding shell.

[0020] As a preferred embodiment of the switch cabinet of the present utility model, wherein: the rain receiving member includes a bolt slidably sleeved with the second sliding hole, and a container is arranged on the bolt.

[0021] The beneficial effects of the switch cabinet of the present utility model are as follows: by providing a chimney and an ash baffle, it is avoided that dust enters from the chimney opening, and fine dust particles enter the circuit board, causing short circuit of the circuit, reducing the risk of equipment failure or damage.

[0028] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1

[0032] Reference Figures 1 to 5 , which is the first embodiment of the utility model, provides a dust blocking mechanism, which prevents dust from entering from the chimney 103 by setting the dust blocking component 100, and prevents fine dust particles from entering the circuit board to cause a short circuit, thereby reducing the risk of equipment failure or damage.

[0033] Specifically, the ash blocking assembly 100 includes a chimney 103, an ash blocking member 101 disposed at the top of the chimney 103, and a cabinet 102 disposed at the bottom of the chimney 103; wherein the cabinet 102 is provided with ventilation holes connected to the chimney 103; wherein an exhaust fan is disposed at the top of the chimney 103.

[0034] Among them, under normal conditions, the dust blocking member 101 blocks the outlet at the top of the chimney 103 to prevent dust and rain from entering the chimney 103.

[0035] In summary, by setting the dust blocking assembly 100, the air flow enters the chimney 103 from the ventilation holes of the cabinet body 102. After starting the exhaust fan, the air flow rises and generates a thrust air flow through the exhaust fan, pushing the dust blocking member 101 out. After the air flow flows out, it is filled with new cold air flow again. After repeated cycles, the chimney 103 remains dry, preventing dust from entering from the chimney 103 opening, and small dust particles enter the circuit board, causing a short circuit in the circuit, reducing the risk of equipment failure or damage.

[0036] Embodiment 2

[0037] Refer to Figures 1 to 5 , which is the second embodiment of the present utility model. Different from the previous embodiment, by setting the chimney 103 and the dust blocking member 101, it is possible to prevent dust from entering from the chimney 103 opening, and small dust particles enter the circuit board, causing a short circuit in the circuit, reducing the risk of equipment failure or damage.

[0038] Specifically, 101 includes a protective cover 101b that is slidably sleeved on the top of the chimney 103.

[0039] A rain shield 101c is provided on the top of the protective cover 101b.

[0040] A number of first sliding holes are formed in the protective cover 101b and are evenly arranged in a circumferential direction around the axis of the protective cover 101b.

[0041] A fixing block 101d that is slidably sleeved with the first sliding hole is provided on the outer wall of the chimney 103.

[0042] A number of cutting net pieces 101a are provided on one side of the fixing block 101d close to the bottom end of the first sliding hole.

[0043] The vertical projection area of the rain shield 101c is larger than the vertical projection area of the protective cover 101b.

[0044] Among them, a fixing block 101d that is slidably sleeved with the first sliding hole is provided on the outer wall of the chimney 103, and the fixing block 101d prevents the protective cover 101b from being pushed by the air flow and separated from the chimney 103.

[0045] A number of cutting net pieces 101a are provided on one side of the fixing block 101d close to the bottom end of the first sliding hole. When the first sliding hole is blocked by a spider web, the cutting net pieces 101a cut the spider web that closes the first sliding hole when the protective cover 101b is blown up by the air flow.

[0046] The vertical projection area of the rain shield 101c is larger than that of the protective cover 101b, which is beneficial to the rain shield 101c blocking the first sliding hole on the protective cover 101b, preventing rainwater from entering through the gap between the first sliding hole and the chimney 103, thus preventing the chimney 103 from getting damp and preventing the humid air in the chimney 103 from entering the cabinet 102 again.

[0047] In summary, by setting up the chimney 103 and the ash blocking member 101, when the exhaust fan is started, after the air rises, the original space is filled by the air entering the ventilation holes of the cabinet 102. After forming an air current, a relatively large thrust is generated by the exhaust fan. The air current pushes the top inner wall of the protective cover 101b to make the protective cover 101b rise. The first sliding hole of the protective cover 101b is limited by the fixing block 101d to prevent the protective cover 101b from detaching from the chimney 103. When the fixing block 101d abuts against the bottom end of the first sliding hole, the air current flows out from the first sliding hole. At the same time, when the first sliding hole is covered by a spider web, the cutting net piece 101a cuts the spider web when the protective cover 101b rises, preventing the exhaust efficiency of the air current from being reduced and preventing dust from entering through the chimney 103 opening. Fine dust particles enter the circuit board, causing a short circuit in the circuit and reducing the risk of equipment failure or damage.

[0048] Embodiment 3

[0049] Referring to Figures 1 to 5 , this is the third embodiment of the present utility model. Different from the previous embodiment, by setting up the rain receiving member 201 and the guiding member 202, when manually opening the outdoor cabinet 102 for dehumidification, it can be avoided that when rain comes, the worker forgets to close the door of the cabinet 102, resulting in rainwater entering the cabinet and wetting the electronic equipment, and preventing the risk of equipment short circuit.

[0050] Specifically, the shielding assembly 200 includes a rain receiving member 201 and a guiding member 202 provided on the rain receiving member 201.

[0051] The guiding member 202 includes a guiding shell 202b. A second sliding hole is opened on the guiding shell 202b, and a spring 202a is provided on the bottom inner wall of the guiding shell 202b.

[0052] The rain receiving member 201 includes a bolt 201a slidably sleeved with the second sliding hole, and a container 201b is provided on the bolt 201a.

[0053] Wherein, the nut of the bolt 201a limits the second sliding hole. Under normal conditions, the container 201b is located at the top of the ventilation hole of the cabinet 102 under the push of the spring 202a.

[0054] In summary, by providing the rain receiving member 201 and the guiding member 202, when it rains, rainwater falls into the container 201b, causing the weight of the container 201b to increase and driving the bolt 201a to press down, causing the spring 202a to undergo elastic deformation. During this process, the bolt 201a slides along the second sliding hole until the container 201b descends to block the ventilation hole of the cabinet body 102. Since the ventilation hole is in communication with the electronic devices in the cabinet body 102, it is possible to prevent rainwater from entering the cabinet and wetting the electronic devices when the worker forgets to close the door of the outdoor cabinet body 102 when opening it manually for moisture removal during rainy days, thus preventing the risk of equipment short - circuit.
