Abstract
Description
Technical Field
[0001] This utility model relates to the field of generator technology, specifically a protective structure for generators. Background Technology
[0002] As a core device that converts other forms of energy, such as mechanical energy, thermal energy, and wind energy, into electrical energy, generators are widely used in power systems, industrial production, transportation, emergency power supply, and other scenarios. Their stable operation is directly related to the reliability of energy supply. As an important component of generators, the protective structure plays a crucial role in protecting internal core components such as stators, rotors, windings, and bearings from the influence of the external environment, extending equipment life, and ensuring operational safety.
[0003] Chinese Utility Model Patent Publication No. CN217656509U discloses a generator with a bearing protection structure. The specification of this generator states that by setting up an oil storage bar, an oil storage trough, and an oil pipe, lubricating oil is injected through the oil pipe. The oil storage bar absorbs the injected lubricating oil. When the shaft presses against the bearing, the oil storage bar is squeezed out, squeezing out a small amount of lubricating oil, forming a lubricating film. This ensures lubrication between the bearing and the shaft, preventing direct friction between them. The high temperature generated by direct friction protects the bearing body and extends the generator's service life. However, while this generator with a bearing protection structure can achieve rapid lubrication, it lacks a quick-alignment structure for the protective cover and shell, making misalignment during installation easy and affecting its subsequent normal use, resulting in poor practicality. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to provide a protective structure for generators. It can effectively solve the problem in the prior art that although it can achieve rapid lubrication, it does not have a quick alignment structure for the protective cover and the protective shell, which makes it easy for the two to be misaligned during installation, thus affecting its subsequent normal use and resulting in poor practicality.
[0005] The technical solution adopted by this utility model is: a protective structure for a generator, including a protective shell, a base, a rear cover, and a generator body. The generator body is snapped into the inside of the protective shell. A positioning ring and a positioning block are fixedly installed at the end of the protective shell away from the rear cover. A protective cover is provided at the end of the protective cover away from the protective shell. A through groove is opened at the end of the protective cover away from the protective shell. A heat dissipation mesh is fixedly installed along the inner edge of the through groove. A fixing plate is fixedly installed at the end of the protective cover near the protective shell. An installation plate is fixedly installed at the end of the protective cover away from the protective shell.
[0006] Preferably, a reinforcing block is fixedly installed at one end of the base near the protective shell. The reinforcing block has a triangular cross-section. The base has a positioning hole extending from top to bottom. The base and the protective shell are fixedly installed.
[0007] The above technical solution, which uses a triangular cross-section reinforcing block fixed to the base and protective shell, can enhance the connection rigidity of the two by utilizing the structural stability of the triangle, disperse the vibration load of the generator body during operation, prevent the base from deforming, and improve its service life.
[0008] Preferably, a limiting groove is provided at one end of the protective cover near the protective shell, and the limiting groove is the same size as the positioning ring.
[0009] Through the above technical solution, by cooperating with the limiting groove of the protective cover and the positioning ring of the protective shell, the positioning ring can be inserted into the limiting groove to form a ring positioning structure, which can play a role in pre-positioning.
[0010] Preferably, the protective cover has a positioning block at one end near the protective shell, and the positioning block and the positioning groove are plugged in.
[0011] Through the above technical solution, the design of the positioning block and positioning groove can play a limiting role when installing the protective cover and protective shell, preventing the protective cover and protective shell from rotating easily when fixed. In conjunction with the ring positioning of the limiting groove and positioning ring, it can facilitate subsequent welding and other fixing, and avoid misalignment during fixing.
[0012] Preferably, a bearing is fixedly installed near the center of the mounting plate, and the bearing is adapted to the output shaft of the generator body.
[0013] By using the above technical solution, the bearing at the center of the mounting plate is adapted to the output shaft of the generator body, which can form radial support for the output shaft and avoid problems such as wear and tear that are easy to occur during long-term use.
[0014] Preferably, the through slots and the heat dissipation mesh are in one-to-one correspondence, and there are multiple identical through slots and heat dissipation meshes that are distributed in a ring around the center line of the protective cover.
[0015] Through the above technical solution, multiple annularly distributed channels and heat dissipation mesh can form a uniform airflow channel, which can prevent the temperature inside the protective shell from being too high and affecting the operation of the equipment. In addition, the heat dissipation mesh can block the entry of external debris, thus providing protection while ensuring heat dissipation, and is suitable for outdoor or dusty environments.
[0016] Preferably, a cover is fixedly installed on the protective shell, and a positioning bolt is threaded through the outer wall of the rear cover, the positioning bolt passing through the rear cover and extending into the interior of the protective shell.
[0017] Through the above technical solution, the cover on the protective shell can cover the rear end of the generator, forming rear protection. The rear cover is locked to the protective shell by positioning bolts, which facilitates disassembly and maintenance and improves its installation efficiency.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Example 1: As Figure 1-6 As shown, the present invention provides a protective structure for a generator, including a protective shell 1, a base 2, a rear cover 5, and a generator body 7. The generator body 7 is snapped into the inside of the protective shell 1. A positioning ring 8 and a positioning block 9 are fixedly installed at the end of the protective shell 1 away from the rear cover 5. A protective cover 10 is provided at the end of the protective shell 1 away from the rear cover 5. A through groove 13 is opened at the end of the protective cover 10 away from the protective shell 1. A heat dissipation mesh 14 is fixedly installed at the inner edge of the through groove 13. A fixing plate 15 is fixedly installed at the end of the protective cover 10 close to the protective shell 1, and an installation plate 17 is fixedly installed at the end of the protective cover 10 away from the protective shell 1.
[0030] Specifically, a reinforcing block 3 is fixedly installed at one end of the base 2 near the protective shell 1. The reinforcing block 3 has a triangular cross-section. The base 2 has a positioning hole 4 running through it from top to bottom. The base 2 and the protective shell 1 are fixedly installed. The advantage is that the design of fixing the reinforcing block 3 with the triangular cross-section to the base 2 and the protective shell 1 can enhance the connection rigidity of the two by utilizing the structural stability of the triangle. It can also disperse the vibration load of the generator body 7 during operation, prevent the base 2 from deforming, and improve its service life.
[0031] Specifically, a limiting groove 11 is provided at one end of the protective cover 10 near the protective shell 1. The limiting groove 11 is the same size as the positioning ring 8. The advantage is that, through the cooperation of the limiting groove 11 of the protective cover 10 and the positioning ring 8 of the protective shell 1, the positioning ring 8 can be inserted into the limiting groove 11, thereby forming a ring positioning structure, which can play a role in pre-positioning.
[0032] Specifically, a positioning block 9 is provided at one end of the protective cover 10 near the protective shell 1. The positioning block 9 and the positioning groove 12 are plugged in. The advantage is that the design of the positioning block 9 and the positioning groove 12 can play a limiting role when installing the protective cover 10 and the protective shell 1, preventing the protective cover 10 and the protective shell 1 from rotating easily when fixed. With the ring positioning of the limiting groove 11 and the positioning ring 8, it is convenient to carry out subsequent welding and other fixing, and avoid misalignment during fixing.
[0033] Example 2: Figure 2-6 As shown, this is an improvement on the previous embodiment.
[0034] Specifically, a bearing 16 is fixedly installed near the center of the mounting plate 17. The bearing 16 is adapted to the output shaft of the generator body 7. The advantage is that the bearing 16 at the center of the mounting plate 17 is adapted to the output shaft of the generator body 7, which can form radial support for the output shaft and avoid problems such as wear and tear that are easy to occur during long-term use.
[0035] Specifically, the through slots 13 and the heat dissipation mesh 14 are one-to-one. Both the through slots 13 and the heat dissipation mesh 14 are provided in multiples and are distributed in a ring around the center line of the protective cover 10. The advantage is that the multiple ring-shaped through slots 13 and heat dissipation mesh 14 can form a uniform airflow channel, which can prevent the temperature inside the protective cover 1 from being too high and affecting the operation of the equipment. In addition, the heat dissipation mesh 14 can block the entry of external debris, thus providing protection while ensuring heat dissipation, and is suitable for outdoor or dusty environments.
[0036] Specifically, a cover 18 is fixedly installed on the protective housing 1, and a positioning bolt 6 is threaded through the outer wall of the rear cover 5. The positioning bolt 6 passes through the rear cover 5 and extends into the interior of the protective housing 1. The advantage is that the cover 18 on the protective housing 1 can cover the rear end of the generator to form rear end protection, and the rear cover 5 is locked to the protective housing 1 by the positioning bolt 6, which is convenient for disassembly and maintenance and can improve its installation efficiency.
[0037] Working Principle: During use, the triangular cross-section reinforcing block 3 is fixed to the base 2 and the protective shell 1. The triangular structure enhances the connection rigidity, dissipates vibration loads on the generator body 7 during operation, prevents deformation of the base 2, and extends its service life. The positioning ring 8 of the protective shell 10 engages with the limiting groove 11, forming a ring-shaped positioning structure for pre-positioning. The positioning block 9 and positioning groove 12 limit the movement of the protective shell 10 and 1 during installation, preventing rotation during fixation. The engagement of the limiting groove 11 and positioning ring 8 further enhances the connection. The shape positioning facilitates subsequent welding and other fixing, avoiding misalignment during fixing. The bearing 16 at the center of the mounting plate 17 is adapted to the output shaft of the generator body 7, providing radial support for the output shaft and preventing wear and tear over long-term use. Multiple annularly distributed through slots 13 and heat dissipation mesh 14 form a uniform airflow channel, preventing excessive temperature inside the protective shell 1 from affecting equipment operation. Furthermore, the heat dissipation mesh 14 can block external debris from entering, providing protection while ensuring heat dissipation, making it suitable for outdoor or dusty environments. The cover 18 on the protective shell 1 can cover the rear end of the generator, forming rear-end protection. The rear cover 5 is locked to the protective shell 1 by positioning bolts 6, facilitating disassembly and maintenance and improving installation efficiency.
