Description

Technical Field

[0001] This utility model belongs to the field of motor cooling technology, and in particular relates to an induced draft device for high-voltage motors that is easy to install and disassemble. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. It is prone to generating heat during operation. Currently, some motors employ an air-to-air cooling structure, which mainly includes an external air-cooling mechanism, a cooler, and an internal air-cooling mechanism. The external air-cooling mechanism primarily consists of a fan shroud and a centrifugal fan, which drives the airflow. The cooler mainly comprises numerous parallel air ducts. The air inlets of the ducts connect to the air outlets of the fan shroud, while the air outlets connect to the internal air-cooling mechanism. This isolates the internal airflow of the motor from the external airflow, allowing heat exchange between the internal and external airflow within the cooler to achieve motor cooling.

[0003] Chinese Patent Publication No. CN 215646530 U provides a motor air-cooled air-exhaust device. Its internal structure effectively avoids the generation of eddies and turbulence, reduces air resistance, and provides a relatively uniform exhaust volume, which is beneficial to improving cooling efficiency.

[0004] However, the overall structure of the aforementioned patent does not provide a detailed description of the outer shell structure. It can be seen directly from the attached drawings that the outer shell structure is integrated, while the centrifugal fan is located inside the lower part of the integrated outer shell. This makes it inconvenient to disassemble and install the device during routine maintenance or when the centrifugal fan malfunctions. Utility Model Content

A centrifugal fan is fixedly connected to the front end surface of the power shaft.

[0008] Preferably, a semi-circular air guide ring is fixedly connected inside the housing and at the outer edge of the mounting port. Air guide plates extending into the inner surfaces of the housing are fixedly connected to both sides of the top opening of the air guide ring.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] Please see Figs. 1-3 This utility model provides a technical solution: a high-voltage motor exhaust fan that is easy to install and disassemble, including a housing 1 with an open top, an installation port that is laterally opened through the lower part of the rear surface of the housing 1, a convex ring 2 coaxial with the installation port that is fixedly connected to the rear surface of the housing 1, a connecting plate 3 that is detachably installed on the rear surface of the convex ring 2, a shaft hole that is laterally opened through the middle of the rear surface of the connecting plate 3, a power shaft 4 that is laterally rotatably connected inside the shaft hole, and a centrifugal fan 5 that is fixedly connected to the front surface of the power shaft 4.

[0022] The lower part of the front surface of the casing 1 has a horizontally through-hole for an air inlet corresponding to the centrifugal fan 5.

[0023] In this embodiment, the device has an installation port on the rear surface of the housing 1, and a protruding ring 2 is provided at the rear of the installation port. A connecting plate 3 is detachably installed on the outside of the protruding ring 2, and the centrifugal fan 5 is installed on the connecting plate 3. When the device needs to be maintained, the centrifugal fan 5 can be removed from the device by simply removing the connecting plate, which is very convenient and improves the maintenance convenience of the device.

[0024] The device draws outside air into the interior of the housing 1 through the air inlet at the front of the housing 1 via a centrifugal fan 5, and finally discharges it through the opening at the top of the housing 1.

[0025] In actual operation, the device requires the motor or other drive structure to be installed at the rear of the connecting plate 3, so that the power shaft 4 can be rotated and the centrifugal fan 5 can be rotated synchronously.

[0026] Furthermore, a semi-circular air guide ring 6 is fixedly connected inside the housing 1 and at the outer edge of the mounting opening. Air guide plates 8 extending into the inner surfaces of the housing 1 are fixedly connected to the top opening of the air guide ring 6 on both sides. The two ends of the two air guide plates 8 are fixedly connected to the inner surfaces of the housing 1.

[0027] Multiple partition plates 9 are fixedly connected to the top of the inside of the casing 1.

[0028] In this embodiment, the opening of the air guide ring 6 forms an air outlet 7 under the action of the two air guide plates 8. The air guide ring 6 and the two air guide plates 8 can restrict the air entering the housing 1 so that it can only be discharged from the air outlet 7, thereby increasing the air pressure. Then, under the action of multiple partition plates 9, it can ensure that the blown air can be evenly discharged from the opening at the top of the housing 1.

[0029] Furthermore, an air duct ring 10 is fixedly connected to the front surface of the housing 1 and the outer edge of the air inlet.

[0030] In this embodiment, the air-guiding ring 10 is funnel-shaped, which can guide the airflow into the device and ensure the stability of its flow.

[0031] Furthermore, each of the two rear upper sides of the housing 1 is fixedly connected to a connecting seat 11, and each connecting seat 11 has a connecting hole.

[0032] The top of the housing 1 is fixedly connected to an extension frame 12 that matches the outline of its top opening. The upper surface of the extension frame 12 has multiple vertically penetrating mounting slots 13.

[0033] In this embodiment, the connecting seat 11, connecting hole, extension frame 12 and mounting slot 13 facilitate the installation of the device on other structures, thus improving the ease of installation.

[0034] The working principle and usage process of this utility model are as follows: After the utility model is installed, the device draws outside air into the interior of the housing 1 through the air inlet at the front end of the housing 1 via the centrifugal fan 5, and finally discharges it through the opening at the top of the housing 1. The device has an installation port on the rear surface of the housing 1, and a protruding ring 2 is provided at the rear of the installation port. A connecting plate 3 is detachably installed on the outside of the protruding ring 2, and the centrifugal fan 5 is installed on the connecting plate 3. When the device needs to be maintained, the centrifugal fan 5 can be removed from the device by simply removing the connecting plate, which is very convenient and improves the maintenance convenience of the device.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
