Description

Technical Field

[0001] The utility model relates to the technical field of electrical cabinets, in particular to a ventilation device on the top of an electrical cabinet. Background Art

[0002] The electrical cabinet is a cabinet made of steel material and used to protect the normal operation of components. With the development of the power industry, electrical cabinets are used more and more. Since the electrical cabinet is in a humid environment or is installed outdoors, it will cause moisture inside the electrical cabinet. If the ventilation effect inside the cabinet cannot be guaranteed, the electrical cabinet will be damp, moldy and corroded, and the electrical components will be damaged. In severe cases, dangerous situations such as leakage or short circuit will occur. For some electrical cabinets used in indoor environments, the internal environmental gas flow is poor, and the gas flow inside the cabinet cannot be achieved by the flow of external gas alone. This will only cause the internal environmental temperature of the cabinet to become higher and higher, and ultimately affect the normal operation of the equipment.

[0003] The existing ventilation method for electrical cabinets is mostly to set ventilation holes on the top to dissipate heat inside the cabinet. However, for electrical cabinets used in some outdoor environments, when it rains, the exposed ventilation holes will cause rainwater to easily enter the electrical cabinet, causing damage to the components in the electrical cabinet, but failing to effectively protect the electrical cabinet. Therefore, a ventilation device on the top of the electrical cabinet is needed. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a top ventilation device for an electrical cabinet, which is used to solve the problem of preventing rainwater from entering the interior of the cabinet when ventilating the cabinet in the prior art.

[0005] In order to achieve the above purpose and other related purposes, the utility model provides the following technical solutions:

[0006] A ventilation device on the top of an electrical cabinet, comprising:

[0007] A cabinet body, wherein two groups of ventilation plates are symmetrically arranged on the upper side of the cabinet body, and ventilation holes are arranged in the ventilation plates;

[0008] A ventilation component includes a ventilation cabin arranged on the upper side of a cabinet, a ventilation grille is arranged on the side wall of the ventilation cabin, the ventilation cabin is extended upward out of the cabinet, a guard plate is arranged on the upper side of the ventilation cabin, a grille baffle is extended circumferentially from the guard plate, a ventilation fan is arranged in the ventilation cabin, and an air outlet of the ventilation fan is arranged toward the guard plate.

[0009] To implement the above technical solution, two sets of ventilation plates are symmetrically arranged on the upper side of the cabinet, which can assist in heat dissipation and ventilation inside the cabinet, and the cover plate on the top of the cabinet extends out of the cabinet in a horizontal direction, thereby preventing rainwater from entering the cabinet through the side ventilation plates.

[0010] In order to improve the gas flow effect inside the cabinet, a ventilation cabin is arranged on the upper side of the cabinet, and a ventilation fan is arranged in the ventilation cabin. The ventilation fan is used to accelerate the gas flow inside the cabinet to ensure the heat dissipation efficiency inside the cabinet. A ventilation grille is arranged on the side wall of the ventilation cabin to facilitate the timely discharge of the air flow inside the cabinet. A guard plate is arranged on the upper side of the ventilation cabin, and a grille baffle is arranged on the circumferential extension of the guard plate. The guard plate is extended by the grille baffle to prevent external rainwater from entering the ventilation cabin and causing damage to the interior of the cabinet.

[0011] In an embodiment of the present invention, the grille baffle is arranged to be gradually inclined downward in a direction away from the ventilation grille.

[0012] To implement the above technical solution, the grille baffle is gradually tilted downward in a direction away from the ventilation grille, and the grille baffle is used to form an eave shape around the guard plate, thereby increasing the possibility of preventing rainwater from entering the ventilation cabin.

[0013] In an embodiment of the present invention, the lowest end height of the grille baffle is higher than the uppermost end horizontal height of the ventilation grille.

[0014] To implement the above technical solution, the lowest end height of the grille baffle is higher than the uppermost horizontal height of the ventilation grille, which can ensure the ventilation effect of the ventilation grille and effectively prevent rainwater from entering the ventilation cabin through the ventilation grille.

[0015] In one embodiment of the utility model, a grille base is provided at the bottom of the ventilation cabin, the grille base is arranged along the periphery of the ventilation cabin, and the grille base is detachably connected to the cabinet.

[0016] To implement the above technical solution, the setting of the grille base can not only provide stable support for the ventilation grille, but also facilitate the installation of the ventilation grille on the cabinet, thereby improving the stability and convenience of installation.

[0017] In one embodiment of the utility model, a vertical guide plate with an open end is circumferentially arranged on the upper side of the cabinet, and the vertical guide plate extends upward from the upper end surface of the cabinet. In addition, a guide plate is arranged downwardly inclined at the open end of the vertical guide plate on the upper side of the cabinet.

[0018] To implement the above technical solution, a vertical guide plate with an open end is arranged circumferentially on the upper side of the cabinet. The vertical guide plate can be used to form a fence. When rainwater falling on the grille baffle falls to the upper side of the cabinet, the vertical guide plate can prevent rainwater from flowing out of the cabinet from all sides, and instead flows out of the cabinet uniformly from the guide plate, which makes it convenient to consider the installation position of the rainwater outflow direction when installing the cabinet, making the cabinet more reasonable during use.

[0019] In one embodiment of the present invention, a waterproof bottom plate is provided at the bottom of the ventilation cabin along the vertical direction, and the height of the waterproof bottom plate is higher than the height of the vertical guide plate.

[0020] To implement the above technical solution, setting the height of the waterproof bottom plate higher than the height of the vertical guide plate can prevent rainwater from accumulating on the upper side of the solid and flooding the waterproof bottom plate into the ventilation cabin, thereby affecting the normal use of electrical components inside the cabinet.

[0021] As described above, the utility model is a ventilation device for the top of an electrical cabinet, which has the following beneficial effects: by symmetrically arranging two groups of ventilation plates on the upper side edges of the cabinet body, it can assist in heat dissipation and ventilation of the interior of the cabinet body, and the cover plate on the top of the cabinet body extends out of the cabinet body in a horizontal direction, thereby preventing rainwater from entering the interior of the cabinet body through the side ventilation plates.

[0022] In order to improve the gas flow effect inside the cabinet, a ventilation cabin is arranged on the upper side of the cabinet, and a ventilation fan is arranged in the ventilation cabin. The ventilation fan is used to accelerate the gas flow inside the cabinet to ensure the heat dissipation efficiency inside the cabinet. A ventilation grille is arranged on the side wall of the ventilation cabin to facilitate the timely discharge of the air flow inside the cabinet. A guard plate is arranged on the upper side of the ventilation cabin, and a grille baffle is arranged on the circumferential extension of the guard plate. The guard plate is extended by the grille baffle to prevent external rainwater from entering the ventilation cabin and causing damage to the interior of the cabinet.

It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0029] See also Figures 1 to 3 The utility model provides a ventilation device on the top of an electrical cabinet, comprising two groups of ventilation plates 2 symmetrically arranged on the sides of the upper side of a cabinet body 1, ventilation holes 3 are arranged in the ventilation plates 2, and a ventilation component comprises a ventilation cabin 4 arranged on the upper side of the cabinet body 1, a ventilation grille 5 is arranged on the side wall of the ventilation cabin 4, the ventilation cabin 4 extends upward out of the cabinet body 1, a guard plate 6 is arranged on the upper side of the ventilation cabin 4, a grille baffle 7 is circumferentially extended from the guard plate 6, a ventilation fan 8 is arranged in the ventilation cabin 4, and an air outlet of the ventilation fan 8 is arranged toward the guard plate 6.

[0030] By symmetrically arranging two groups of ventilation plates 2 on the upper side of the cabinet 1, it is possible to assist in heat dissipation and ventilation inside the cabinet 1, and the cover plate on the top of the cabinet 1 extends out of the cabinet 1 in the horizontal direction, so as to prevent rainwater from entering the interior of the cabinet 1 through the side ventilation plates 2.

[0031] In order to improve the gas flow effect inside the cabinet 1, a ventilation cabin 4 is arranged on the upper side of the cabinet 1, and a ventilation fan 8 is arranged in the ventilation cabin 4. The ventilation fan 8 is used to accelerate the gas flow inside the cabinet 1 to ensure the heat dissipation efficiency in the cabinet 1.

A guard plate 6 is arranged on the upper side of the ventilation cabin 4, and a grille baffle 7 is circumferentially extended from the guard plate 6. The grille baffle 7 is used to extend the guard plate 6 to prevent external rainwater from entering the ventilation cabin 4 and causing damage to the interior of the cabinet 1.

[0032] The grille baffle 7 is gradually tilted downward in the direction away from the ventilation grille 5. By gradually tilting the grille baffle 7 downward in the direction away from the ventilation grille 5, the grille baffle 7 is used to form an eaves shape around the guard plate 6, thereby increasing the possibility of preventing rainwater from entering the ventilation cabin 4.

[0033] The lowest end height of the grille baffle 7 is higher than the uppermost horizontal height of the ventilation grille 5. Setting the lowest end height of the grille baffle 7 higher than the uppermost horizontal height of the ventilation grille 5 can ensure the ventilation effect of the ventilation grille 5 and effectively prevent rainwater from entering the ventilation cabin 4 through the ventilation grille 5.

[0034] A grille base 9 is provided at the bottom of the ventilation cabin 4, and the grille base 9 is arranged along the periphery of the ventilation cabin 4. The grille base 9 is detachably connected to the cabinet 1.

[0035] A vertical guide plate 10 with an open end is circumferentially arranged on the upper side of the cabinet 1, and the vertical guide plate 10 extends upward from the upper end surface of the cabinet 1, and a guide plate 11 is arranged downwardly inclined on the open end of the vertical guide plate 10 on the upper side of the cabinet 1. By arranging a vertical guide plate 10 with an open end circumferentially arranged on the upper side of the cabinet 1, the vertical guide plate 10 can be used to form a fence. When rainwater falling on the grille baffle 7 falls to the upper side of the cabinet 1, the vertical guide plate 10 can prevent rainwater from flowing out of the cabinet 1 from all sides, and uniformly flow out of the cabinet 1 from the guide plate 11, which is convenient for considering the installation position of the rainwater outflow direction when installing the cabinet 1, so that the cabinet 1 is more reasonable during use.

[0036] A waterproof bottom plate 12 is provided at the bottom of the ventilation cabin 4 in the vertical direction. The height of the waterproof bottom plate 12 is higher than the height of the vertical guide plate 10. Setting the height of the waterproof bottom plate 12 higher than the height of the vertical guide plate 10 can prevent rainwater from accumulating on the upper side of the solid and flooding the waterproof bottom plate 12 into the ventilation cabin 4, thereby affecting the normal use of the electrical components inside the cabinet 1.

[0037] The utility model can assist in heat dissipation and ventilation of the interior of the cabinet by symmetrically arranging two groups of ventilation plates on the upper side of the cabinet, and the cover plate on the top of the cabinet extends out of the cabinet in a horizontal direction, thus preventing rainwater from entering the interior of the cabinet through the side ventilation plates.

[0038] In order to improve the gas flow effect inside the cabinet, a ventilation cabin is arranged on the upper side of the cabinet, and a ventilation fan is arranged in the ventilation cabin. The ventilation fan is used to accelerate the gas flow inside the cabinet to ensure the heat dissipation efficiency inside the cabinet. A ventilation grille is arranged on the side wall of the ventilation cabin to facilitate the timely discharge of the air flow inside the cabinet. A guard plate is arranged on the upper side of the ventilation cabin, and a grille baffle is arranged on the circumferential extension of the guard plate. The guard plate is extended by the grille baffle to prevent external rainwater from entering the ventilation cabin and causing damage to the interior of the cabinet.

[0039] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. All equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
