Description

Technical Field

[0001] The utility model relates to the technical field of blowers, in particular to an electric cabinet structure. Background Art

[0002] Existing magnetic levitation blowers are generally directly installed on brackets or have a simple outer cover sleeved outside them. The noise generated by the magnetic levitation blowers will cause serious noise pollution to the environment. In order to reduce the noise of the magnetic levitation blowers, the existing solution is to lay sound insulation cotton on the inner side of the outer cover. For example, a cabinet structure applied to a magnetic levitation blower is proposed in the patent document with the patent number 202221402857.2. However, since an air inlet needs to be left on one side of the outer cover, a large amount of noise will spread from the air inlet. Therefore, this design has limited effect on reducing noise.

Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present utility model. Each technical feature in the present utility model can be combined interactively on the premise of not conflicting with each other.

[0031] Referring to Figures 1 to 5 , an embodiment of the present utility model provides an electric cabinet structure, which is applied to a magnetic levitation blower and can reduce the noise pollution of the magnetic levitation blower to the outside world.

[0032] The electric cabinet structure of this embodiment includes a cabinet body 100, a first partition 110, a second partition 120, and a third partition 130. The first partition 110 is vertically arranged, and the first partition 110 divides the interior of the cabinet body 100 into a control room 170 and a wind chamber. The control room 170 is used to place components such as a circuit board, a main switch chassis, and a frequency converter. Most of the line structures for connecting various equipment components are also arranged in the control room 170, which can avoid the exposure of the line structures and thus improve the safety of the equipment components. The first partition 110 extends in the left-right direction, so that the control room 170 is located at the rear side of the wind chamber.

[0033] The second partition 120 is vertically arranged in the wind chamber, and the third partition 130 is horizontally arranged in the wind chamber. The second partition 120 and the third partition 130 are respectively perpendicular to the first partition 110. The second partition 120 and the third partition 130 both extend in the front-rear direction. The lower end of the second partition 120 is connected to the left end or the right end of the third partition 130. The wind chamber is divided into three parts: a blower cavity 140, an air inlet cavity 150, and a wind guiding cavity 160 by the second partition 120 and the third partition 130. Among them, the air inlet cavity 150 is located on the left side or the right side of the blower cavity 140, and the wind guiding cavity 160 is located on the lower side of the blower cavity 140. The lower end of the air inlet cavity 150 is communicated with one end of the wind guiding cavity 160, and a first ventilation opening 131 is provided at the other end of the wind guiding cavity 160. The wind guiding cavity 160 is communicated with the blower cavity 140 through the first ventilation opening 131.

[0034] A second vent is provided on the first partition 110. The two sides of the second vent are respectively communicated with the control room 170 and the air blast chamber 140. A main air inlet and a secondary air inlet are provided on the side wall surface of the cabinet body 100. Among them, the main air inlet is communicated with the air inlet chamber 150, and the secondary air inlet is communicated with the control room 170. An exhaust vent 142 is provided on the upper wall surface of the cabinet body 100, and the exhaust vent 142 is communicated with the air blast chamber 140.

[0035] It can be understood that the body of the magnetic levitation blower is installed in the air blast chamber 140. The third partition 130 is used not only for separating the air blast chamber 140 and the air guiding chamber 160, but also for supporting the body of the magnetic levitation blower, and can provide an installation space for the body of the magnetic levitation blower. The air outlet of the magnetic levitation blower is arranged towards the exhaust vent 142 of the cabinet body 100. When the magnetic levitation blower is turned on, the outside air enters the interior of the cabinet body 100 under the action of the magnetic levitation blower. Among them, the air entering from the main air inlet flows along the air inlet chamber 150 to the air guiding chamber 160, and enters the air blast chamber 140 through the first vent 131, then enters the body of the magnetic levitation blower, and is discharged through the exhaust vent 142. The air entering from the secondary air inlet flows into the control room 170, enters the air blast chamber 140 through the second vent, then enters the body of the magnetic levitation blower, and is discharged through the exhaust vent 142.

[0036] In this embodiment, the electric cabinet structure further includes a first sound-absorbing cotton 143. The first sound-absorbing cotton 143 is laid on the front side wall surface, the rear side wall surface, the left side wall surface and the right side wall surface of the air blast chamber 140. The first sound-absorbing cotton 143 can absorb the noise generated when the magnetic levitation blower operates in the air blast chamber 140, thereby reducing the noise pollution of the magnetic levitation blower to the outside.

[0037] It can be understood that since the first partition 110 divides the interior of the cabinet body 100 into an air chamber and the control room 170, placing the components of the control system such as the circuit board and the main switch chassis on one side of the control room 170 is more convenient for users to control and can make the cable layout more regular and safe.

[0038] In addition, since the air chamber is divided into a blast chamber 140, an air inlet chamber 150, and a wind guiding chamber 160 by using the second partition 120 and the third partition 130, the air inlet chamber 150 and the wind guiding chamber 160 together form an "L"-shaped flow path, which can extend the flow trajectory of air entering the magnetic levitation blower from the main air inlet, allowing the air to enter the blast chamber 140 from the lower side of the blast chamber 140. The first sound insulation cotton can be laid around the front, back, left, and right of the blast chamber 140, thereby increasing the noise absorption capacity of the magnetic levitation blower and reducing the noise pollution to the outside. Since the distance between the blast chamber 140 and the ground is raised by the wind guiding chamber 160 below the blast chamber 140, the wind guiding chamber 160 forms an isolation belt between the blast chamber 140 and the ground, which can also play a certain sound insulation effect and further reduce the noise pollution to the outside.

[0039] Moreover, the second partition 120 can block the air entering from the main air inlet, thereby reducing the dust particles from entering the blast chamber 140, reducing the influence of the dust particles on the magnetic levitation blower, reducing the noise of the magnetic levitation blower to a certain extent, and being able to extend the service life of the magnetic levitation blower.

[0040] In some embodiments, the electric cabinet structure further includes a second sound insulation cotton 161, and the second sound insulation cotton 161 is laid on the front side wall, the rear side wall, and the side wall away from the air inlet chamber 150 of the wind guiding chamber 160. The second sound insulation cotton 161 can eliminate the noise generated when the air enters the wind guiding chamber 160 at a high speed, and further reduce the noise pollution generated by the magnetic levitation blower to the outside during operation.

[0041] In this embodiment, the wind guiding chamber 160 is arranged below the blast chamber 140, the air inlet chamber 150 is arranged on the right side of the blast chamber 140, the first ventilation opening 131 is located at the right end of the upper wall surface of the wind guiding chamber 160, and the second sound insulation cotton 161 is laid on the left side wall, the front side wall, and the rear side wall of the wind guiding chamber 160. Among them, the second sound insulation cotton 161 laid on the rear side wall of the wind guiding chamber 160 is connected to the front wall surface of the first partition 110, the first sound insulation cotton 143 laid on the rear side wall of the blast chamber 140 is connected to the front wall surface of the first partition 110, and the first sound insulation cotton 143 laid on the right side wall of the blast chamber 140 is connected to the left side wall surface of the second partition 120.

[0042] In some embodiments, the electric cabinet structure further includes a wind hood 171, the wind hood 171 is arranged in the control room 170 and is connected to the first partition 110. The wind hood 171 is located at the position of the first ventilation opening 131, and it is provided with an air guiding chamber. The outlet end of the air guiding chamber is communicated with the first ventilation opening 131, and the inlet end of the air guiding chamber is opened downward.

[0043] It can be understood that the setting of the air hood 171 can guide air to enter the blast chamber from the control chamber 170. Since the air intake cavity is arranged with an opening facing downward, the air passing through the control chamber 170 will flow through more space before entering the air intake cavity, taking away part of the heat in the control chamber 170 and improving the safety of the control chamber 170.

[0044] In some embodiments, the upper side wall surface of the air intake cavity is in an arc shape, protruding upward, which can allow air to enter the air intake cavity more smoothly and flow to one side of the air chamber under the guidance of the air hood 171. In addition, due to the smooth arc surface inside the air intake cavity, it can reduce noise to a certain extent and further reduce the noise pollution to the environment.

[0045] In some embodiments, the electrical cabinet structure further includes a first filter cotton mounting frame 174, which is connected to the inner side wall surface of the control chamber 170 and arranged around the secondary air inlet.

[0046] The first filter cotton mounting frame 174 is used to mount the filter cotton. The filter cotton mounted on the first filter cotton mounting frame 174 can filter the air entering the interior of the cabinet 100 from the secondary air inlet, preventing dust particles from entering the interior of the cabinet 100 from the secondary air inlet. Moreover, since the filter cotton mounted on the first filter cotton mounting frame 174 has a certain wind-blocking effect, it can also improve the sound absorption effect and further reduce the noise pollution to the environment.

[0047] It can be understood that the first filter cotton mounting frame 174 provides an installation space for the filter cotton, and the filter cotton can be disassembled from the first filter cotton mounting frame 174 to facilitate the replacement or cleaning of the filter cotton to ensure the air filtration effect at the secondary air inlet.

[0048] In some embodiments, the electrical cabinet structure further includes a guide plate 172, which is arranged in the control chamber 170. Its upper end is connected to the first filter cotton mounting frame 174. The guide plate 172 extends downward obliquely, jointly forming a diversion cavity with an opening facing downward with the first filter cotton mounting frame 174. The diversion cavity is communicated with the secondary air inlet and the control chamber 170.

[0049] It can be understood that the air entering through the secondary air inlet flows downward under the guiding action of the guide plate 172 and enters the control chamber 170, then flows to the first ventilation opening 131 and enters the air chamber through the first ventilation opening 131. It can guide the air to flow through more space in the control chamber 170 before entering the first ventilation opening 131, so that the air can take away more heat in the control chamber 170 and prevent the control chamber 170 from overheating. Moreover, due to the setting of the guide plate 172, the guide plate 172 can play a certain role in blocking the air, further improving the sound absorption effect and reducing the noise pollution to the environment.

[0050] In some embodiments, the electric cabinet structure further includes a first maintenance door 141 and a second maintenance door 173, and the cabinet body 100 is provided with a first maintenance opening and a second maintenance opening. Among them, the first maintenance opening is arranged on the front side wall surface of the cabinet body 100, and the first maintenance opening is communicated with the air chamber. The first maintenance door 141 is movably connected to the cabinet body 100 and can open or close the first maintenance opening. The second maintenance opening is arranged on the rear side wall surface of the cabinet body 100, and the second maintenance opening is communicated with the control room 170. The second maintenance door 173 is movably connected to the cabinet body 100 and can open or close the second maintenance opening.

[0051] It can be understood that setting the first maintenance door 141 can facilitate the user to open or close the air chamber, so as to repair components such as the magnetic levitation blower located in the air chamber. Setting the second maintenance door 173 can facilitate the user to open or close the control room 170, so as to repair control systems such as the circuit board and the main switch chassis located in the control room 170.

[0052] In this embodiment, the transformer is installed in the air guide cavity 160, and the differential pressure transmitter is installed on the side wall of the air blowing cavity 140. After the first maintenance door 141 is opened, the transformer and the differential pressure transmitter can also be repaired or replaced.

[0053] It can be understood that the first sound-absorbing cotton 143 laid on the front side wall surface of the air blowing cavity 140 and the second sound-absorbing cotton 161 laid on the front side wall surface of the air guide cavity 160 are both arranged on the rear side wall surface of the first maintenance door 141. The first maintenance door 141 can be of a single-door panel type or a double-door panel type. In this embodiment, the first maintenance door 141 is of a double-door panel type, and the first sound-absorbing cotton 143 and the second sound-absorbing cotton 161 on the same side door panel are made into an integral setting.

[0054] The second maintenance door 173 can be of a single-door panel type or a double-door panel type. In this embodiment, the second maintenance door 173 is of a double-door panel type, and a control panel convenient for the user to operate is installed on one of the door panels of the second maintenance door 173, and the control panel is electrically connected to the control system located in the control room 170.

[0055] It can be understood that both the first maintenance door 141 and the second maintenance door 173 are provided with door locks to prevent unauthorized opening and improve the safety of the electric cabinet.

[0056] It is understandable that the first partition 110 and the third partition 130 are provided with wire holes to facilitate electrical connection between various electrical components. In this embodiment, the transformer is installed in the air guide cavity 160, the differential pressure transmitter is installed on the side wall of the air blowing cavity 140, the circuit structure of the magnetic suspension blower is sent to the transformer located in the air guide cavity 160 through the wire hole of the third partition 130, and the transformer located on one side of the air chamber is sent to the control room 170 through the wire hole of the first partition 110.

[0057] In some embodiments, the electric cabinet structure further includes a second filter cotton installation frame 151, which is connected to the inner wall surface of the air inlet chamber 150 and is arranged around the main air inlet. The second filter cotton installation frame 151 is used to install filter cotton. The filter cotton installed on the second filter cotton installation frame 151 can filter the air entering the cabinet 100 from the main air inlet, and can prevent dust particles from entering the cabinet 100 from the main air inlet. Moreover, since the filter cotton installed on the second filter cotton installation frame 151 has a certain windproof effect, it can also improve the silencing effect and further reduce noise pollution to the environment.

[0058] It is understandable that the second filter cotton installation frame 151 provides an installation space for the filter cotton, and the filter cotton can be removed from the second filter cotton installation frame 151 to facilitate replacement or cleaning of the filter cotton to ensure the air filtering effect at the main air inlet.

[0059] In some embodiments, the electric cabinet structure further includes a main air inlet door 152 and an auxiliary air inlet door 175. The main air inlet door 152 covers the main air inlet, and is movably connected to the side wall of the cabinet 100, and can open or close the main air inlet. The auxiliary air inlet door 175 covers the auxiliary air inlet, and is movably connected to the side wall of the cabinet 100, and can open or close the auxiliary air inlet.

[0060] In this embodiment, a mesh structure is provided on the main air inlet door 152 and the auxiliary air inlet door 175, which can block the air entering the cabinet 100 to a certain extent, reduce the impurities entering the cabinet 100 while ensuring the air volume, and reduce the noise to a certain extent.

[0061] It can be understood that since the main air inlet door 152 and the auxiliary air inlet door 175 can open or close the main air inlet and the auxiliary air inlet, it is convenient to disassemble, replace or clean the filter cotton located at the main air inlet and the auxiliary air inlet.

[0062] In this embodiment, the main air inlet door 152, the auxiliary air inlet door 175, the first maintenance door 141 and the second maintenance door 173 are all installed on the cabinet 100 in a hinged manner. Figure 1 , Figure 2 and Figure 3, the cabinet body 100 is in the first state, and the first maintenance door 141, the second maintenance door 173, the main air inlet door 152, and the auxiliary air inlet door 175 are all in the closed state; refer to Figure 4 and Figure 5 , the cabinet body 100 is in the second state, and the first maintenance door 141, the second maintenance door 173, the main air inlet door 152, and the auxiliary air inlet door 175 are all in the open state.

[0063] In some embodiments, refer to Figure 1 and Figure 6 , the electric cabinet structure further includes a corridor 200. The outlet end of the corridor 200 is detachably connected to the cabinet body 100. The corridor 200 is hollow to form a cavity, and the cavity is communicated with the main air inlet. A flange connector 210 is provided at the inlet end of the corridor 200.

[0064] It can be understood that by setting the corridor 200, the connection of the pipeline can be realized through the flange connector 210, the air intake position of the magnetic levitation blower can be transferred to a position far from the electric cabinet structure, long-distance air intake can be achieved, the flexibility of the installation and layout of the electric cabinet structure can be improved, and the user is prevented from taking air in places with corrosive gases, which affects the service life of the equipment.

[0065] In some embodiments, the electric cabinet structure further includes a third filter cotton installation frame 220. The third filter cotton installation frame 220 is connected to the inner wall surface of the cavity and is used for installing filter cotton. The filter cotton installed on the third filter cotton installation frame 220 can filter the air entering the cavity, prevent dust particles from entering the interior of the cabinet body 100 through the corridor 200, and moreover, since the filter cotton installed on the third filter cotton installation frame 220 has a certain wind blocking effect, it can also improve the sound absorption effect and further reduce the noise pollution to the environment.

[0066] It can be understood that the third filter cotton installation frame 220 provides an installation space for the filter cotton, and the filter cotton can be detached from the third filter cotton installation frame 220 to facilitate the replacement or cleaning of the filter cotton.

[0067] In this embodiment, a third maintenance door 230 is provided on the side wall of the corridor 200. The third maintenance door 230 is of a single-door panel type. By opening the third maintenance door 230, it is convenient for the user to disassemble and assemble the filter cotton located in the cavity. In this embodiment, the third maintenance door 230 is hinged to the side wall of the corridor 200.
