Description

Technical Field

[0001] This utility model relates to the field of cabinet dust removal technology, specifically a dust removal structure for a mining low-voltage switchgear. Background Technology

[0002] Mining low-voltage switchgear is an important power distribution device in the mine power system. It is mainly used to control and distribute low-voltage power and ensure the stable operation of underground electrical equipment. Due to the complex mine environment, the air often contains a lot of dust and particulate matter. Switchgear is in a high dust environment for a long time, which can easily lead to dust accumulation on internal components, affecting heat dissipation performance and the reliability of electrical connections. Therefore, the dustproof and dust removal design of switchgear is crucial to ensure its long-term stable operation.

[0003] Common filter plates are easily clogged by dust, usually requiring manual replacement, which is frequent and increases maintenance costs. In addition, manual cleaning of filter plates is inefficient and difficult to completely remove deeply attached dust. Long-term accumulation may affect the heat dissipation and insulation performance of the switchgear. Therefore, we propose a dust removal structure for mining low-voltage switchgear to solve the above problems. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] The purpose of this invention is to overcome the shortcomings of existing low-voltage switchgear dust removal structures that are easily clogged and require frequent manual replacement.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A dust removal structure for a mining low-voltage switchgear includes a mounting frame and a filter plate. Several limiting strips are fixedly connected inside the mounting frame in a linear array. The filter plate movably passes through the limiting strips. A through slot for mounting the limiting strips is provided at the top of the mounting frame. Connecting strips are movably connected to both sides of the mounting frame, and several cleaning blocks are fixedly connected to the side of each connecting strip closest to the filter plate. The cleaning blocks are in contact with the surface of the filter plate. Cleaning frames are movably connected between adjacent filter plates, and the cleaning blocks are located inside the cleaning frames. A driving assembly is fixedly connected to the inner side of the mounting frame to control the movement of the connecting strips along the filter plate. A vibration assembly is fixedly connected to the mounting frame to control the longitudinal vibration of the connecting strips.

[0009] Furthermore, the drive assembly includes a rotating rod, a synchronous pulley, and a synchronous belt. The rotating rod is symmetrically arranged, and synchronous pulleys are fixedly connected to both ends of the rotating rod. A synchronous belt is sleeved on the outer side of the synchronous pulleys at the same horizontal height, and the synchronous pulleys and synchronous belts constitute a belt drive structure.

[0010] Furthermore, the synchronous pulley is movably connected to the inside of the mounting frame via a rotating rod, and a servo motor is fixedly connected inside the mounting frame, with the output end of the servo motor fixedly connected to the top end of the rotating rod.

[0011] Furthermore, the drive assembly also includes sleeve blocks, and a set of staggered and symmetrical sleeve blocks are fixedly connected to the outer side of the timing belt. The top and bottom ends of the connecting strip pass through the sleeve blocks respectively, and the connecting strip is movably connected to the sleeve blocks.

[0012] Furthermore, a dust collection box is movably connected to the bottom corner of the mounting frame, and dust collection grooves are constructed on both sides of the mounting frame to collect dust on the filter plate, with the dust collection box located at the bottom of the dust collection groove.

[0013] Furthermore, the vibration assembly includes a movable block and a folding spring. The top of each connecting strip is movably fitted with a movable block, and the top of the movable block is movably connected to the top of the mounting frame. The folding spring is fixedly connected inside the movable block, and the bottom end of the folding spring is fixedly connected to the top end of the connecting strip.

[0014] Furthermore, the vibration assembly also includes vibration strips, which are symmetrically arranged and fixedly connected to the bottom two sides of the mounting frame. The vibration strips are wavy, and the bottom end of the connecting strip is in contact with the surface of the vibration strip.

[0015] 3. Beneficial Effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] (1) In this solution, the dust falls into the dust collection box under the action of gravity by the set drive component. By pulling out the dust collection box, the dust can be poured out in a unified manner. By setting cleaning blocks and cleaning frames on both sides of the mounting frame and controlling them to move back and forth on the surface of the filter plate several times, it is beneficial to concentrate and clean the dust on the surface of the filter plate into the dust collection tank, effectively carry out centralized treatment of dust, avoid dust clogging the filter plate, increase the service life of the filter plate, and reduce the replacement frequency of the filter plate.

[0018] (2) In this scheme, when the bottom of the connecting strip abuts against the concave part of the vibrating strip, the connecting strip is pressed down by the folding spring. This reciprocating motion causes the connecting strip to vibrate, thereby driving the cleaning block to vibrate longitudinally inside the cleaning frame. This is beneficial to improving the cleaning efficiency of the cleaning block on the surface of the filter plate. The longitudinal vibration is also helpful to remove the dust that is deeply adhered to the surface of the filter plate. Attached Figure Description

[0024] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] Example 1:

[0026] like Figure 1-4 As shown, this utility model provides a technical solution: a dust removal structure for a mining low-voltage switchgear, including a mounting frame 1 and a filter plate 2. The mounting frame 1 is fixedly connected to the switchgear cabinet by bolts, and is generally located at the bottom of the back side of the cabinet. Several limiting strips 3 are fixedly connected inside the mounting frame 1, and the limiting strips 3 are distributed in a linear array. The filter plate 2 moves through the limiting strips 3, and a through groove 4 for installing the limiting strips 3 is opened at the top of the mounting frame 1. The filter plate 2 can be installed inside the mounting frame 1 by passing through the through groove 4, and the filter plate 2 can be replaced by passing through the limiting strips 3. The filter plate 2 is used to filter dust. To block dust outside the switch cabinet, connecting strips 5 are movably connected to both sides of the mounting frame 1, and several cleaning blocks 6 are fixedly connected to the side of the connecting strips 5 closest to the filter plate 2. The length of the cleaning blocks 6 is less than the distance between the limiting strips 3, so that the cleaning blocks 6 can move longitudinally between the limiting strips 3. The cleaning blocks 6 are in contact with the surface of the filter plate 2. A cleaning frame 7 is movably connected between adjacent filter plates 2, and the cleaning blocks 6 are located on the inner side of the cleaning frame 7. A drive assembly 8 is fixedly connected to the inner side of the mounting frame 1 to control the movement of the connecting strips 5 along the filter plate 2. A vibration assembly 9 is fixedly connected to the mounting frame 1 to control the longitudinal vibration of the connecting strips 5.

[0027] Example 2:

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, the drive assembly 8 includes a rotating rod 801, a synchronous pulley 802, and a synchronous belt 803. The rotating rod 801 is symmetrically arranged, and synchronous pulleys 802 are fixedly connected to both ends of the rotating rod 801. The synchronous belt 803 is sleeved on the outer side of the synchronous pulleys 802 at the same horizontal height, and the synchronous pulleys 802 and the synchronous belt 803 form a belt drive structure. The synchronous pulleys 802 are movably connected to the inside of the mounting frame 1 through the rotating rod 801. A servo motor 10 is fixedly connected inside the mounting frame 1, and the output end of the servo motor 10 is connected to the top of the rotating rod 801. The drive assembly 8 also includes a sleeve block 804. A set of staggered and symmetrical sleeve blocks 804 are fixedly connected to the outer side of the synchronous belt 803. That is, a sleeve block 804 is provided on each side of the mounting frame 1. The top and bottom ends of the connecting strip 5 pass through the sleeve block 804 respectively, and the connecting strip 5 is movably connected to the sleeve block 804. A dust collection box 11 is movably connected to the bottom corner of the mounting frame 1. Dust collection grooves 12 are constructed on both sides of the mounting frame 1 to collect dust on the filter plate 2, and the dust collection box 11 is located at the bottom of the dust collection groove 12.

[0029] The servo motor 10 is started, driving the rotating rod 801 to rotate, causing the two synchronous pulleys 802 on it to rotate. Under the action of the synchronous belt 803, the synchronous pulley 802 on the other side rotates synchronously with the rotating rod 801, driving the sleeve block 804 on it to rotate with the synchronous belt 803. Since the connecting strip 5 moves through the sleeve block 804, the connecting strip 5 moves along the side of the mounting frame 1 and against the limiting strip 3, driving the cleaning block 6 to clean the dust on the surface of the filter plate 2. At the same time, the cleaning frame 7 on the outside of the cleaning block 6 moves synchronously, thereby pushing the dust towards the direction of the cleaning block 6. The dust is pushed until it is between adjacent limit bars 3 into the dust collection trough 12. Under the action of its own gravity, the dust falls into the dust collection box 11. By pulling out the dust collection box 11, the dust can be easily emptied. By setting cleaning blocks 6 and cleaning frames 7 on both sides of the mounting frame 1 and controlling them to move back and forth on the surface of the filter plate 2 several times, it is beneficial to concentrate and clean the dust on the surface of the filter plate 2 into the dust collection trough 12, effectively carry out centralized dust treatment, avoid dust clogging the filter plate 2, improve the service life of the filter plate 2, and reduce the replacement frequency of the filter plate 2.

[0030] Example 3:

[0031] like Figure 1 and Figure 3As shown, the vibration assembly 9 includes a movable block 901 and a folding spring 902. The top of each connecting strip 5 is movably fitted with a movable block 901, and the top of the movable block 901 is movably connected to the top of the mounting frame 1. The folding spring 902 is fixedly connected inside the movable block 901, and the bottom end of the folding spring 902 is fixedly connected to the top end of the connecting strip 5. The vibration assembly 9 also includes a vibration strip 903, which is symmetrically arranged and fixedly connected to the bottom two sides of the mounting frame 1. The vibration strip 903 is wavy, and the bottom end of the connecting strip 5 is in contact with the surface of the vibration strip 903.

[0032] When the connecting strip 5 moves horizontally along the mounting frame 1, the bottom of the connecting strip 5 is always in contact with the surface of the vibrating strip 903. Since the vibrating strip 903 is wavy and its surface is uneven, when the bottom of the connecting strip 5 contacts the protrusion of the vibrating strip 903, the connecting strip 5 will be pushed upward, causing the folding spring 902 to be compressed and shortened. When the bottom of the connecting strip 5 contacts the concave part of the vibrating strip 903, the connecting strip 5 will be pressed downward by the folding spring 902. This process repeats, causing the connecting strip 5 to vibrate, thereby driving the cleaning block 6 to vibrate longitudinally inside the cleaning frame 7. This helps to improve the cleaning efficiency of the cleaning block 6 on the surface of the filter plate 2. The longitudinal vibration makes it easier to remove the dust that is deeply adhered to the surface of the filter plate 2.

[0033] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
