Description

Technical Field

[0001] The present application relates to the technical field of electrical equipment, and in particular to a fire-fighting electrical cabinet with high efficiency in heat dissipation and ventilation. Background Art

[0002] Fire protection electrical cabinet refers to a comprehensive electrical equipment that integrates power, control and protection. It is mainly used for electrical control and protection of fire protection systems to ensure the normal operation of fire protection systems.

[0003] Some existing fire protection electrical cabinets are mainly composed of a cabinet body, a controller and electrical components, wherein the controller and the electrical components are electrically connected, and the electrical components are electrically connected to external related equipment through wires, so that the controller can perform electrical control and protection functions on external related equipment, and filters are installed on both sides of the cabinet body to achieve passive heat dissipation of the components in the cabinet, so that the components in the cabinet are not easy to accumulate heat, thereby realizing the heat dissipation protection function of the fire protection electrical cabinet.

[0004] However, in the above process, since one side of the filter is exposed to the external environment, dust is easily accumulated on the side of the filter exposed to the external environment during the air circulation between the cabinet and the outside world, causing the dust to block the filter, thereby affecting the heat dissipation effect of the components inside the cabinet. Summary of the invention

[0005] The present application proposes a fire-fighting electrical cabinet with high efficiency in heat dissipation and ventilation, which has the advantages of high efficiency in heat dissipation and ventilation, and is used to solve the problem that dust blocks the filter screen, thereby affecting the heat dissipation effect of the components inside the cabinet.

[0006] To achieve the above-mentioned purpose, the present application adopts the following technical solution: an efficient heat dissipation and ventilation fire protection electrical cabinet, comprising: a cabinet body, a cabinet door hinged on the front side of the cabinet body for closing the cabinet body, a controller fixedly installed at the upper side of the cabinet body cavity, an electrical component fixedly installed at the lower side of the cabinet body cavity, the electrical component and the controller are electrically connected through a wire, and the electrical component is electrically connected to external related equipment through a wire; The two side walls of the cabinet body are symmetrically provided with sockets on the side of the electrical components facing the cabinet door. Side tubes are inserted into the top and bottom sockets, and a center tube is inserted into the socket in the middle. Both ends of the side tubes and the center tube are opened. Connecting plates are provided on both sides of the cabinet body. The side tubes and the center tube are fixed to the sockets through the connecting plates on both sides. Both the side tubes and the center tube are made of heat-conducting materials.

[0007] Furthermore, the connecting plate on one side is fixedly connected with the corresponding side tube and the central tube, and the connecting plate on the other side is plug-fixed with the corresponding side tube and the central tube.

[0008] Furthermore, a No. 1 through hole is axially equidistantly provided inside the side tube and on one side facing the center tube, and the No. 1 through hole connects the inner cavity of the cabinet and the inner cavity of the side tube; a No. 2 through hole is axially equidistantly provided inside the center tube and on one side facing the side tube, and the No. 2 through hole connects the inner cavity of the cabinet and the inner cavity of the center tube; a No. 1 filter is fitted in the inner cavity of the side tube, and a No. 2 filter is fitted in the inner cavity of the center tube.

[0009] Furthermore, the diameters at both ends of the side tube are larger than the diameter in the middle of the side tube, and the No. 1 through hole is arranged in the middle of the side tube.

[0010] Furthermore, both the No. 1 filter and the No. 2 filter are rigid filters, thereby improving the convenience of replacement.

[0011] Furthermore, a transmission wheel is provided on one side of the side tube and the center tube, and the transmission wheel is a hollow wheel. The sides of the No. 1 filter screen and the No. 2 filter screen facing the transmission wheel are fixedly connected to the corresponding transmission wheel. The outer side of the transmission wheel is transmission-connected with a belt, and a motor is fixedly installed on the side of a connecting plate facing the belt. The connecting plate away from the motor is plug-connected and fixed with the corresponding side tube and center tube. A power wheel is fixedly installed on the end of the output shaft of the motor, and the power wheel is transmission-connected with the transmission wheel in the middle position.

[0012] Furthermore, a fan is installed on the connection plate away from the motor to transport air to the side tubes and the center tube.

[0013] This application has the following beneficial effects: The present application provides a fire-fighting electrical cabinet with high efficiency in heat dissipation and ventilation. By setting side tubes, center tubes and connecting plates, the flowing air passes through the side tubes and center tubes, thereby removing the heat transferred from the components inside the cabinet to the side tubes and center tubes. In this process, when dust accumulates on the inner sides of the side tubes and center tubes, outside air can still pass through the side tubes and center tubes, thereby reducing the influence of dust on the heat dissipation effect of the device.

[0014] By setting the side tubes, the center tube, the first filter and the second filter, when the air flow rate of the outside air is faster, the side tubes will attract the air flowing through the center tube, thereby prompting the air to flow longitudinally in the cabinet, thereby extending the air movement path in the cabinet, thereby improving the heat dissipation effect of the device.

[0015] By setting the side tube, the center tube, the No. 1 filter, the No. 2 filter and the transmission wheel, the transmission wheel is used to drive the No. 1 filter and the No. 2 filter to rotate in the side tube and the center tube, so that the relative positions of the No. 1 filter and the No. 2 filter and the corresponding No. 1 through hole and the No. 2 through hole are not fixed, thereby avoiding dust from contacting the fixed position of the corresponding filter for a long time, reducing the probability of blockage of the device, and reducing the influence of dust on the heat dissipation effect of the device.

[0016] Through the arrangement of the side tube, the center tube, the No. 1 filter, the No. 2 filter and the transmission wheel, when parts of the No. 1 filter and the No. 2 filter are rotated to a position away from the corresponding through holes, the air passing through the side tube and the center tube will form a tangential contact with parts of the above-mentioned filters, thereby prompting the dust accumulated on the inner side of the part of the filter to be blown away from the side tube and the center tube, thereby further reducing the influence of dust on the heat dissipation effect of the device.

[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] Example 1: Please refer to Figure 1-Figure 5, a fire-fighting electrical cabinet with high efficiency in heat dissipation and ventilation, comprising a cabinet body 1, a cabinet door (existing technology, not shown in the figure) hinged on the front side of the cabinet body 1, which is used to close the cabinet body 1, a controller 2 is fixedly installed at the upper side of the inner cavity of the cabinet body 1, an electrical component 3 is fixedly installed at the lower side of the inner cavity of the cabinet body 1, the electrical component 3 is electrically connected to the controller 2 through a wire, and the electrical component 3 is electrically connected to external related equipment through a wire (existing technology, not shown in the figure), and jacks 4 are symmetrically provided on the two side walls of the cabinet body 1 and located on the side of the electrical component 3 facing the cabinet door, side tubes 5 are inserted into the top and bottom jacks 4, and a center tube 6 is inserted into the jack 4 in the middle position, and both the side tubes 5 and the center tube 6 are opened at both ends, and connecting plates 7 are provided on both sides of the cabinet body 1, and the connecting plates 7 on one side are fixedly connected with the corresponding side tubes 5 and the center tube 6, and the connecting plates 7 on the other side are plugged and fixed with the corresponding side tubes 5 and the center tube 6, and both the side tubes 5 and the center tube 6 are made of heat conductive materials.

[0022] When in use, naturally flowing air passes through the side tubes 5 and the center tube 6, thereby removing the heat transferred from the controller 2 and the electrical components 3 in the cabinet 1 to the side tubes 5 and the center tube 6. In this process, when dust accumulates on the inner sides of the side tubes 5 and the center tube 6, outside air can still pass through the two, thereby reducing the influence of dust on the heat dissipation effect of the device. When it is necessary to inspect or repair the controller 2 and the electrical components 3, separate the connecting plate 7 on one side from the corresponding side tube 5 and center tube 6, and then control and move the connecting plate 7 on the other side so that the side tube 5 and the center tube 6 leave the cabinet 1.

[0023] Example 2: Please refer to Figure 1-Figure 5 This embodiment is a further improvement of the first embodiment, and the improvement lies in that: a No. 1 through hole 8 is axially equidistantly provided inside the side tube 5 and on the side facing the center tube 6, and the No. 1 through hole 8 connects the inner cavity of the cabinet 1 with the inner cavity of the side tube 5; a No. 2 through hole 9 is axially equidistantly provided inside the center tube 6 and on the side facing the side tube 5, and the No. 2 through hole 9 connects the inner cavity of the cabinet 1 with the inner cavity of the center tube 6; a No. 1 filter screen 10 is fitted in the inner cavity of the side tube 5, and a No. 2 filter screen 11 is fitted in the inner cavity of the center tube 6.

[0024] Through the above arrangement, the air in the cabinet 1 and the outside air can be exchanged and circulated through the No. 1 through hole 8 and the No. 2 through hole 9. At the same time, the two are blocked by the corresponding No. 1 filter 10 and the No. 2 filter 11, so that the dust in the air is blocked outside the cabinet 1, so that the heat dissipation effect of the device is further improved.

[0025] See also Figure 1-Figure 5 The diameters at both ends of the side tube 5 are larger than the diameter in the middle of the side tube 5 , and the No. 1 through hole 8 is opened in the middle position of the side tube 5 .

[0026] When the air flow rate of the outside air is fast (windy weather or with the addition of a fan), and the air passes through the side tube 5, it will attract the air in the cabinet 1 through the No. 1 through hole 8 (Venturi effect). Since the distance between the side tube 5 and the central tube 6 is relatively close, and part of the air passing through the central tube 6 will enter the cabinet 1 from the No. 2 through hole 9, the attraction generated at the No. 1 through hole 8 will partially act on the air flowing out of the central tube 6, thereby prompting part of the air to flow longitudinally in the cabinet 1, thereby extending the movement path of part of the air in the cabinet 1, thereby improving the heat dissipation effect of the device.

[0027] Example 3: Please refer to Figure 1-Figure 5 , this embodiment is a further improvement of the second embodiment, and its improvement lies in that: a transmission wheel 12 is provided on one side of the side tube 5 and the center tube 6, and the transmission wheel 12 is a hollow wheel. The first filter screen 10 and the second filter screen 11 are both rigid filter screens. The first filter screen 10 and the second filter screen 11 are fixedly connected to the corresponding transmission wheel 12 on the side facing the transmission wheel 12. The outer side of the transmission wheel 12 is transmission-connected with a belt 13, and a motor 14 is fixedly installed on the side of a connecting plate 7 facing the belt 13. The connecting plate 7 away from the motor 14 is plug-connected and fixed with the corresponding side tube 5 and the center tube 6. A power wheel 15 is fixedly installed at the end of the output shaft of the motor 14, and the power wheel 15 is transmission-connected with the transmission wheel 12 in the middle position (the transmission wheel 12, the belt 13, and the power wheel 15 are only shown in figure, and can be set as a gear structure in actual application) (in all the above embodiments, a fan can be installed on the connecting plate 7 away from the motor 14 to transport air with a faster flow rate to the side tube 5 and the center tube 6).

[0028] The motor 14 is used to drive the power wheel 15 to rotate, so that the corresponding transmission wheel 12 drives all the transmission wheels 12 to rotate through the belt 13, and then the No. 1 filter 10 and the No. 2 filter 11 are rotated, so that the relative positions of the No. 1 filter 10, the No. 2 filter 11 and the corresponding No. 1 through hole 8, the No. 2 through hole 9 are not fixed, thereby avoiding dust from contacting the fixed positions of the No. 1 filter 10 and the No. 2 filter 11 for a long time, so that the probability of blockage of the device is reduced, thereby reducing the influence of dust on the heat dissipation effect of the device. At the same time, when the No. 1 filter 10 and the No. 2 filter 11 are partially rotated to a position away from the corresponding No. 1 through hole 8, the No. 2 through hole 9, the air passing through the side tube 5 and the center tube 6 will form a tangential contact with part of the dust adhered to the inner side of the No. 1 filter 10 and the No. 2 filter 11, thereby prompting the dust to be blown away from the side tube 5 and the center tube 6, thereby further reducing the influence of dust on the heat dissipation effect of the device.
