Description

Technical Field

[0001] This utility model relates to the field of mining motor technology, specifically to a structure for a ventilation port filter box for a mining car motor. Background Technology

[0002] Electric motors hold an unshakeable position in the field of construction machinery and are known as the "heart" of construction machinery. With the rapid development of the construction machinery industry, electric motors, which are known as the "heart," have been widely used, especially in the field of mining truck manufacturing, where they are indispensable.

[0003] The essence of motor operation is the mutual conversion between electric field and magnetic field. During the mutual conversion between electricity and magnetism, heat loss is inevitable. If heat continues to accumulate in the motor, it will inevitably affect the normal operation of the motor and shorten its service life.

[0004] Heat loss from a motor mainly occurs in two ways: first, heat is dissipated through the temperature difference of the motor's own structural components; second, heat is carried away by the air circulating between the outside and inside the motor. The second method is crucial for motor cooling. However, when heat is dissipated through the circulation of air between the inside and outside of the motor, some impurities such as dust, sand, and gravel from the working environment will inevitably be introduced into the motor. As a result, most of these impurities will remain and accumulate inside the motor, causing serious pollution to the internal cavity. Over time, the accumulation of dust will affect the original ventilation area, resulting in uneven cooling at both ends, which in turn affects the motor's efficiency. Utility Model Content

The air guide plates are V-shaped bends, and several equidistant second drainage holes are provided on the bottom inner wall of the filter body frame body. The position of each second drainage hole is located at the bend of each air guide plate body.

[0008] Preferably, a protective frame is fixedly connected to one side of the filter body frame, and two wire meshes are sequentially installed inside the protective frame.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0020] Please see Figures 1-2 An embodiment of this utility model provides a filter box structure for a motor ventilation port of a mining car, comprising: a filter box body 1.

[0021] In this embodiment, as Figures 1-4 As shown, a water collection tank 8 is fixedly connected inside the filter housing 1, and a first drain hole 9 is provided at both ends of the inner wall of the filter housing 1 near the water collection tank 8. A filter body frame 3 is fixedly connected to one end of the filter housing 1. Several air guide plates 5 are installed inside the filter body frame 3 at equal intervals. The air guide plates 5 are bent in a V shape. Several second drain holes 10 are provided at equal intervals on the bottom inner wall of the filter body frame 3. The position of each second drain hole 10 is set at the bend of each air guide plate 5.

[0022] The water collection tank 8 inside the filter housing 1 can intercept and collect water flowing out of the filter body frame 3, and then discharge the water through the first drain hole 9. The filter body frame 3 has several air guide plates 5 arranged at equal intervals to form a filter body assembly. Each air guide plate 5 in the filter body assembly is V-shaped, so that when the external medium enters the filter body frame 3, it can be blocked at the bend. At the same time, a second drain hole 10 is provided at the bend of each air guide plate 5. The blocked foreign objects flow into the water collection tank 8 through the channel of the second drain hole 10, and then are discharged through the first drain hole 9.

[0023] In this embodiment, as Figures 1-5 As shown, a protective frame 4 is fixedly connected to one side of the filter body frame 3. Two wire meshes 7 are installed in sequence inside the protective frame 4. The wire mesh 7 located on the outer side of the protective frame 4 has a larger aperture than the wire mesh 7 located on the inner side of the protective frame 4. The outermost end of the filter box 1 is equipped with a protective frame 4. Two wire meshes 7 of different specifications are installed inside the protective frame 4. The aperture of the outermost wire mesh 7 is larger than the aperture of the inner wire mesh 7, which can effectively control the size of the particles entering the filter body.

[0024] like Figure 1 and Figure 2 As shown, a rain cover 2 is fixedly connected to one side of the filter housing 1. The filter body frame 3 and the protective frame 4 are both located inside the rain cover 2. By fixing the rain cover 2 to one side of the filter housing 1, rainwater at a certain angle can be effectively prevented from entering the filter.

[0025] Reference Figure 5 A connecting plate 6 is welded to the bottom of the filter housing 1. The connecting plate 6 has threaded holes. The connecting plate 6, together with the threaded holes, can fix the filter housing 1 to the end cover of the motor 11 by bolts.

[0026] Based on the above technical solution, the working steps of this solution are summarized as follows: The water collection tank 8 inside the filter housing 1 can intercept and collect the water flowing out of the filter body frame 3, and then discharge the water through the first drain hole 9. Among them, several air guide plates 5 arranged at equal intervals inside the filter body frame 3 form a filter body assembly. Each air guide plate 5 in the filter body assembly is V-shaped, so that when the external medium enters the filter body frame 3, it can be blocked at the bend. At the same time, a second drain hole 10 is provided at the bend of each air guide plate 5. The blocked foreign objects flow into the water collection tank 8 through the channel of the second drain hole 10, and then are discharged through the first drain hole 9, ensuring the quality of the medium entering the motor. Through multi-layer protection, the cleanliness of the motor body can be effectively guaranteed. At the same time, the installation and removal of the filter housing 1 does not require the disassembly of the motor body, which is convenient for maintenance and saves costs.

[0027] Secondly, the outermost end of the filter housing 1 is equipped with a protective frame 4, and two wire meshes 7 of different specifications are installed inside the protective frame 4. The aperture of the outermost wire mesh 7 is larger than that of the inner wire mesh 7, which can effectively control the size of the particles entering the filter body. At the same time, a rain cover 2 is fixed on one side of the filter housing 1 to effectively prevent rainwater from entering the filter at a certain angle.

[0028] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
