Description

Technical Field

[0001] This application relates to the field of power output device technology, specifically to a magnetically detachable power device. Background Technology

[0002] Our company, in collaboration with other entities, filed a Chinese patent application (application number CN202420156482.9) on September 24, 2024, disclosing a spacer fixing device. This device belongs to the field of spacer installation technology. The spacer fixing device includes a fixing frame, with a lifting ring fixedly connected to the top of the fixing frame. A threaded sleeve is rotatably connected to one end of the fixing frame, and a screw is threadedly connected to the inside of the threaded sleeve. A movable block is fixedly connected to one end of the screw, and a first bevel gear is fixedly connected to one end of the threaded sleeve. A first housing is fixedly connected to the fixing frame, and a motor is disposed inside the first housing. The output shaft of the motor is fixedly connected to a second bevel gear that meshes with the first bevel gear. A conductive sheet is disposed on the first housing, and a magnetic ring is disposed on the outer side of the conductive sheet.

[0003] The spacer fixing device of this patent integrates a motor into the spacer fixing device. Once the spacer fixing device is fixed to the conductor of the overhead transmission line, it usually needs to be maintained for several to more than ten years. However, the motor is only used once when it is fixed and then remains on the fixing device, resulting in extremely low efficiency. At the same time, the presence of the motor also increases the weight of the spacer fixing device, causes the center of gravity to be off-center, and increases the cost. Utility Model Content

[0004] In view of this, this application provides a magnetically detachable power device that allows the motor to be separated from the spacer fixing device. During use, it is connected by magnetic attraction and then outputs power. After use, it can be quickly separated, which not only reduces the weight of the spacer fixing device and lowers the cost, but also makes it easier to use.

[0005] According to one aspect of this application, one embodiment provides a magnetically detachable power device, including an anti-rotation base, a magnetic collar, and a motor. The anti-rotation base has a power shaft hole in the middle and an anti-rotation boss on its surface. The magnetic collar is disposed at the head of the motor, allowing the output shaft of the motor to pass through it. The outer ring of the magnetic collar has an anti-rotation groove. The anti-rotation base and the magnetic collar are made of non-ferromagnetic material. The anti-rotation base and the magnetic collar have corresponding magnetic material fixing holes. One of the following is disposed in the magnetic material fixing holes on the anti-rotation base and the magnetic collar: a magnet, an electromagnet, or a ferromagnetic body that can be attracted by a magnet.

[0006] In some embodiments, the number of anti-rotation slots on the outer ring of the magnetic collar is greater than or equal to the number of anti-rotation protrusions on the anti-rotation seat.

[0007] In some embodiments, the anti-rotation boss on the anti-rotation seat has two or more shapes.

[0008] In some embodiments, the anti-rotation base and the magnetic collar are further provided with screw holes for connecting and fixing the anti-rotation base and the magnetic collar.

[0009] In some embodiments, the electromagnet is a miniature electromagnetic chuck.

[0010] In some embodiments, the motor is a low-voltage motor.

[0011] In some embodiments, a sleeve is provided on the output shaft of the motor for connecting to the power shaft on the spacer bar fixing device.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The present invention relates to a magnetically detachable power device. When the motor head with a magnetic collar is connected to the anti-rotation seat, the two can be combined due to magnetic attraction, which facilitates the motor power output. Moreover, the motor with the magnetic collar can be separated from the anti-rotation seat by external force. This device is not only easy to connect, but also easy to separate.

[0014] 2. The magnetically detachable power device of this utility model has an anti-rotation boss on the anti-rotation seat and an anti-rotation slot on the magnetic collar that cooperate with each other to effectively prevent the power component from rotating and misaligning during operation, ensuring the stability and reliability of power transmission, and improving the working accuracy and service life of the equipment.

[0024] Example:

[0025] Please refer to Figures 1-4 According to one aspect of this application, one embodiment provides a magnetically detachable power device, including an anti-rotation seat 1, a magnetic collar 2, and a motor 3.

[0026] The anti-rotation base 1 is made of aluminum alloy and is square when viewed from the front. It has a circular power shaft hole 5 in the center, and four large countersunk magnetic material fixing holes 8 are evenly distributed around the power shaft hole 5. A ring magnet is fixed inside using countersunk screws. The magnet can be an N52 magnet with a diameter of 12mm, a thickness of 5mm, and an M5 countersunk hole. Four anti-rotation bosses 6 are provided at the four corners of the anti-rotation base 1. The four anti-rotation bosses 6 are of the same height. Two adjacent anti-rotation bosses 6 are rectangular pillars, while the other two are corner pillars. The anti-rotation base 1 also has two screw holes 9, which are also countersunk holes.

[0027] The magnetic collar 2 is also made of aluminum alloy and has an eight-petal flower shape when viewed from the front. Between adjacent petals is an anti-rotation slot 7, and in the center is a large circular hole 10 for the output shaft of the motor 3 to pass through. Around the large circular hole 10, four magnetic material fixing holes 8 are evenly distributed around its circumference. Inside, a ring magnet is fixed with countersunk screws. The magnet can be a 12mm diameter, 5mm thick, M5 countersunk N52 magnet. The magnet on the magnetic collar 2 and the magnet on the anti-rotation seat 1 can attract each other. For example, if the S pole of the magnet on the magnetic collar 2 faces outwards, then the N pole of the magnet on the anti-rotation seat 1 should face outwards, facilitating the attraction between the S and N poles. The magnetic collar 2 also has two screw holes 9, which are also countersunk holes.

[0028] To reduce the weight of the magnetic collar 2, four weight-reducing holes 11 are cut into the magnetic collar 2.

[0029] The magnetic collar 2 is screwed into the head of the motor 3 through the screw hole 9 using a countersunk screw, so that the output shaft of the motor 3 passes through the magnetic collar 2.

[0030] Motor 3 is a 24V DC motor, specifically a 24V DC geared motor.

[0031] A sleeve 4 is provided on the output shaft of the motor 3 for connecting the output shaft of the motor 3 to the power shaft on the spacer bar fixing device 12.

[0032] Please refer to Figure 5 This utility model discloses a magnetically detachable power device. In use, an anti-rotation seat 1 is screwed onto a spacer fixing device 12. Then, a motor 3 with a magnetic collar 2 is inserted into the anti-rotation seat. Due to the attraction of the magnet, the motor with the magnetic collar is attracted to the anti-rotation seat. The anti-rotation protrusion on the anti-rotation seat engages with the anti-rotation slot of the magnetic collar. The sleeve 4 on the output shaft of the motor 3 directly fits onto the power shaft of the spacer fixing device 12. When the motor 3 rotates, it does not rotate with the output shaft but instead drives the power shaft of the spacer fixing device 12, achieving effective output from the motor 3. When the spacer fixing device 12 is clamped or released, pulling the motor 3 forcefully will remove the motor 3 with the magnetic collar 2 from the spacer fixing device 12, achieving separation. If the spacer fixing device 12 is used for the spacer and installed on the overhead power line, after the motor 3 with the magnetic collar 2 is pulled down, the anti-rotation seat 1 will remain on the spacer fixing device 12. When it needs to be removed later, the motor 3 with the magnetic collar 2 can be hoisted onto the spacer fixing device 12 by a drone. Due to the magnetic attraction, the motor 3 with the magnetic collar 2 can be quickly connected to the anti-rotation seat 1. The motor 3 will start, and the spacer fixing device 12 can be removed, thereby removing the spacer from the overhead power line.

[0033] Example 2:

[0034] This example is an improvement on Embodiment 1, specifically by embedding miniature electromagnets into the four magnetic material fixing holes 8 of the magnetic collar 2. The electromagnets are 24V and 12mm in diameter. A power supply that can power the motor 3 is connected to power the electromagnets.

[0035] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
