Description

Technical Field

[0001] The utility model relates to the technical field of coal mine equipment, and particularly relates to an electric control box for coal mine equipment. Background Technique

[0002] In a coal mine shaft, an electric control box needs to be set up for controlling electrical equipment. Due to explosion-proof requirements in the mine, the electric control box is usually an explosion-proof box. The box door of the explosion-proof box adopts a quick-opening design to facilitate the quick opening of the box door. A transparent plate is arranged on the front of the box door to directly view the data displayed by the electronic devices in the box. However, in the mine, there is a lot of dust in the surrounding environment of the coal mine. The dust adhering to the transparent plate will produce a shielding effect on the transparent plate. Therefore, the dust will adhere to the transparent plate, causing the transparent plate to lose its perspective function and affecting the viewing of the numerical values displayed by the electronic devices. As a result, every time it is necessary to view, it is necessary to wipe with hands or clothes. However, the adhesion of coal mine dust is strong. Therefore, the long-term adhered coal mine dust accumulates and thickens, making it difficult to wipe all the dust adhered to the transparent plate, thus affecting the viewing of the electrical numerical values inside the electric control box. Content of the Utility Model

[0003] The purpose of the utility model is to provide an electric control box for coal mine equipment to solve the problems put forward in the above background technique.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] The present utility model provides an electric control box for coal mine equipment as shown in Figures 1-6 , which includes a door body 1. An explosion-proof box 2 for placing electrical components is arranged on the back of the door body 1. A dust-proof mechanism 4 for blocking dust with a transparent plate is arranged on the front of the door body 1. A fixing box 3 for installing the dust-proof mechanism 4 is arranged outside the dust-proof mechanism 4. The dust-proof mechanism 4 includes a dust-proof component and a cleaning component 5. The dust-proof component includes a dust-proof plate 41 and a sealing strip 44. A pushing spring 43 for pushing the dust-proof plate 41 is arranged on one side of the dust-proof plate 41.

[0022] Specifically, the door body 1 and the explosion-proof box 2 form an existing model of QJZ-400 / 1140 vacuum electromagnetic starter. The explosion-proof box 2 is a quick-opening door. A transparent plate for observing the display data of the electronic components inside the door body 1 is arranged on the front of the door body 1.

[0023] Specifically, the back of the fixing box 3 is fixedly connected to the front of the door body 1. A through groove for exposing the transparent plate is opened on one side of the front of the fixing box 3. The dust-proof plate 41 is slidably inserted into the through groove. The vertical cross-sections of the through groove and the dust-proof plate 41 are respectively cross-shaped. A pulling plate 45 is fixedly connected to one side of the front of the dust-proof plate 41. One side of the inner wall of the through groove is fixedly connected to one side of the sealing strip 44. A cavity is opened inside the other side of the fixing box 3. A through hole is opened on one side of the inner wall of the cavity. One end of the dust-proof plate 41 is inserted into the through hole. A baffle 42 is fixedly connected to one end of the dust-proof plate 41. The two ends of the pushing spring 43 are respectively fixedly connected to one side of the baffle 42 and the other side of the inner wall of the cavity.

[0024] Further, the four corners of the fixed box 3 are respectively fixed to the front of the door body 1 by bolts. The area of the through groove is 1.2 times the area of the transparent plate. The dust shield 41 matches the cross-shaped through groove, so that the dust shield 41 can only move horizontally and linearly along the through groove. The pulling plate 45 is fixedly connected to the dust shield 41 by welding. The pulling plate 45 is arranged on one side of the front of the dust shield 41 close to the cleaning assembly 5. The sealing strip 44 is made of rubber material. The sealing strip 44 is arranged on one side of the through groove away from the baffle 42. The sealing strip 44 is fixedly connected to the through groove by gluing. The length of the fixed box 3 is twice the length of the dust shield 41. The length of the cavity is 1.2 times the length of the dust shield 41. The size of the through hole corresponds to the shape of the dust shield 41. The size of the through hole is 1.02 times the size of the dust shield 41. The baffle 42 is a rectangular plate with a size 1.1 times the size of the through hole. The pushing spring 43 is always in a compressed state in the cavity, so that the pushing spring 43 always pushes the baffle 42 to have a tendency to move towards the sealing strip 44. The baffle 42 drives the dust shield 41 to squeeze the sealing strip 44, causing the sealing strip 44 to deform, so as to seal the through groove and realize the dust shielding function for the transparent plate.

[0025] Specifically, the cleaning assembly 5 includes a brush 51. A mounting strip 52 is fixedly connected to the front of the brush 51. A mounting block 54 is fixedly connected to the back of the dust shield 41. A groove is opened on the back of the mounting block 54. A connecting block 53 is fixedly connected to the front of the mounting strip 52. The connecting block 53 is inserted into the groove. A connecting member for connecting the connecting block 53 and the mounting block 54 is arranged inside the connecting block 53. A threaded hole is opened on one side of the mounting block 54. A threaded groove is opened on one side of the connecting block 53. The connecting member includes a fixing bolt 55. The fixing bolt 55 is threadedly inserted into both the threaded hole and the threaded groove.

[0026] Further, the horizontal space of the cross part of the through groove close to the transparent plate is used for the movement of the cleaning assembly 5. The brush 51 is fixedly connected to the back of the mounting strip 52 by bonding. The front of the mounting block 54 is fixedly connected to the back of the dust shield 41 by welding. The size of the groove matches the connecting block 53. The length of the mounting strip 52 corresponds to the height of the transparent plate. The length of the brush 51 is the same as the length of the mounting strip 52. By inserting the connecting block 53 into the groove and threadedly inserting the fixing bolt 55 into the threaded hole and the threaded groove, the connecting block 53 is locked to the mounting block 54, restricting the movement of the connecting block 53, so that the position of the mounting strip 52 is fixed. The brush 51 is composed of multiple bristles. The vertical distance from the back of the mounting strip 52 to the front of the transparent plate is 0.8 times the length of the bristles. After the mounting strip 52 is installed, under the action of the mounting strip 52 and the transparent plate, the bristles will be squeezed and bent, so that when the dust shield 41 is moved, the bristles will tightly contact and fit the front of the transparent plate, cleaning the dust attached to the front of the transparent plate when the dust shield 41 is opened.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
