Description

Technical Field

[0001] The present application relates to the technical field of protective mesh covers, and in particular to an air inlet protective mesh cover. Background Art

[0002] As an important component of industrial production, motor equipment is affected by external environmental factors during long-term operation. In particular, foreign matter such as dust and debris can easily enter the motor through the air inlet, causing motor performance degradation or even failure and shutdown. To address this problem, a protective mesh cover is usually installed at the motor's air inlet to block these foreign matter.

[0003] Most existing protective mesh covers are installed directly at designated locations on the motor bracket. While this installation method can provide some protection, the mounting point itself may have structural weaknesses. Especially in high-vibration environments, bolts can easily loosen over time, rendering the entire protection system ineffective. Furthermore, this type of design often ignores the differentiated requirements of different motor models, limiting its applicability.

[0004] Most similar products currently on the market have failed to effectively solve the stability problem after long-term use, especially under harsh working conditions. In addition, when encountering motors of specific specifications, universal protective covers may not be able to achieve the best fit, further increasing maintenance costs. For this reason, this application proposes an air inlet protective mesh cover to solve the above problems. Utility Model Content

The end of the adjusting rod 11 away from the sliding column 10 is fixedly connected to a ring 12.

[0029] See Figure 2 and Figure 4 The inner wall of the ring 12 is plugged with a positioning pad 2 14, and the inner wall of the positioning pad 2 14 is plugged with a positioning pad 13. The positioning pad 13 and the positioning pad 2 14 are symmetrically arranged on both sides of the ring 12. The positioning pad 13 and the positioning pad 2 14 are both made of rubber, so that when the device is installed with the matching bolts, it can be ensured that the bolts will not contact the ring 12, thereby ensuring the silent effect when the ring 12 is installed, ensuring that the fan will not shake and make abnormal noise when wind passes through, ensuring that it will not have severe friction, and will not be easily rusted.

[0030] See Figure 4 The sliding column 10 is slidably connected to the inner wall of the circular groove 8. The outer diameter of the sliding column 10 is adapted to the inner wall of the circular groove 8, so that the ring 12 can be adjusted to different positions according to different installation spaces, thereby improving the convenience of installation and the scope of application.

[0031] See Figure 3 The bent portion 6 is hooked to the inner wall of the closed joint 3. There are three reinforcing ribs 5 and three bent portions 6, and the three reinforcing ribs 5 and the bent portions 6 are evenly distributed on the outer edge of the disc 4, so that the air inlet protection net cover body 1 and the outer ring 2 can be firmly connected, increasing the overall rigidity, and the outer ring 2 and the closed joint 3 can be connected from three different directions.

[0032] See Figure 2 and Figure 4 The number of the fixing rod 7, the spring 9, the sliding column 10, the adjusting rod 11 and the ring 12 are all three, and the three fixing rods 7, the spring 9, the sliding column 10, the adjusting rod 11 and the ring 12 are distributed in a ring shape on the outer edge of the air inlet protection net cover body 1, and are staggered with the positions of the three reinforcing ribs 5 and the bending part 6, so that the device can be installed from three different positions using three bolts and three rings 12, ensuring the firmness of the installation, the uniformity of the force, and the fact that it will not shake easily when pushed by wind force.

[0033] See Figure 1 and Figure 2 The main body 1 of the air inlet protection mesh cover is made of stainless steel, and the outer ring 2, closed joint 3, reinforcement rib 5 and bending part 6 are all made of aluminum alloy, which has good corrosion resistance and is light in weight and easy to assemble, ensuring strength and not easy to rust.

[0034] See Figure 2 and Figure 3 The outer edges of the three reinforcing ribs 5 are fixedly connected to the air inlet protection mesh cover body 1, so that the three reinforcing ribs 5 can be used to connect several air inlet protection mesh cover bodies 1 with successively larger diameters, thereby forming an overall mesh cover structure.

[0035] Working principle: First, it is necessary to measure and record the precise size parameters of the area to be installed on the surface of the volute, and then customize the appropriate parts according to the measurement results. After checking whether the finished product meets the expected specifications and standards, the next assembly operation can be carried out. Then the device can be taken to the installation site, and the positioning pad 13 and the positioning pad 2 14 can be installed in turn to the upper and lower sides of the ring 12. Then, the space of the installation position can be pulled in turn, and the sliding column 10 can be driven by the adjusting rod 11 to slide on the inner wall position of the circular groove 8, so that the ring 12 can be adjusted to different positions, thereby improving the convenience and applicability of the installation. Then, the bolts can be installed to the inner wall position of the ring 12 to realize the installation of the device. At the same time, it can be ensured that the bolts will not contact the ring 12, thereby ensuring the silent effect when the ring 12 is installed, ensuring that the fan will not shake and produce abnormal noise when wind passes through, ensuring that it will not have severe friction, and will not be easily rusted.
