Description

Technical Field

[0001] The present invention belongs to the technical field of dry-type transformers, and particularly relates to a mine explosion-proof dry-type transformer. Background Art

[0002] A mine explosion-proof dry-type transformer is a transformer specifically designed for explosion-hazardous environments such as underground coal mines. It combines the characteristics of explosion-proof technology and dry-type transformers and can operate safely and reliably in an environment containing explosive mixtures such as gas and coal dust, providing power support for underground equipment.

[0003] When a mine explosion-proof dry-type transformer needs to be used, it needs to be installed on the wall of the mine. However, since the walls in the mine are not flat and the inclination angles of the walls are also different, when workers install the mine explosion-proof dry-type transformer, they also need to replace the corresponding installation parts according to the inclination angle of the mine wall at the installation position, and then use the installation parts to install the mine explosion-proof dry-type transformer on the wall. The steps are complex, reducing the installation efficiency of the mine explosion-proof dry-type transformer. At the same time, since the dry-type transformer needs to dissipate heat during use, heat dissipation holes are usually opened on the side wall of the explosion-proof shell carrying the dry-type transformer to dissipate heat from the dry-type transformer. However, due to the large amount of dust in the mine, after long-term use, the heat dissipation holes opened on the side wall of the explosion-proof shell are easily blocked by dust, and the blockage of the heat dissipation holes will seriously affect the heat dissipation efficiency of the dry-type transformer, resulting in damage to the internal parts of the dry-type transformer and greatly reducing the use effect and reliability of the mine explosion-proof dry-type transformer.

[0021] In the embodiment, the dust cleaning assembly 11 includes a first groove 111 opened on one side wall of the outer shell 1. A second electric slide rail 112 is fixedly connected to the inner wall of the first groove 111. A second slide plate 113 is slidably connected to one side wall of the second electric slide rail 112. A side plate 114 is fixedly connected to one side wall of the second slide plate 113. A plurality of scraping plates 115 are fixedly connected to one side wall of the side plate 114.

Third slide plates 118 are slidably connected to one side walls of the third electric slide rails 117. Fourth electric telescopic rods 1121 are fixedly connected to one side walls of the two third slide plates 118. A connecting plate 119 is fixedly connected to the telescopic ends of the fourth electric telescopic rods 1121. A plurality of winches 1110 are rotatably connected to one side wall of the connecting plate 119. A same hinge 1111 is hinged to the outer walls of the plurality of winches 1110. An L-shaped plate 1112 is fixedly connected to one side wall of the connecting plate 119. A fourth motor 1113 is fixedly connected to one side wall of the L-shaped plate 1112. The output end of the fourth motor 1113 penetrates through the side wall of the L-shaped plate 1112 and is fixedly connected to the side wall of one of the winches 1110. A plurality of push rods 1114 are rotatably connected to one side wall of the connecting plate 119. One ends of the push rods 1114 all penetrate through the side wall of the connecting plate 119 and are fixedly connected to one ends of the corresponding winches 1110. A third groove 1115 is opened at one end of the push rod 1114. A fourth groove 1116 is opened on the inner wall of the third groove 1115. A fifth motor 1117 is fixedly connected to the inner wall of the fourth groove 1116. A rotating rod 1118 is fixedly connected to the output end of the fifth motor 1117.

A sweeping plate 1120 is fixedly connected to one side wall of the connecting block 1119.

[0022] Specifically, after the heat dissipation holes 9 are blocked by dust in the mine, the push rod 1114 and the sweeping plate 1120 can be used to push the dust in the heat dissipation holes 9 out of the heat dissipation holes 9, and sweep the dust outside the heat dissipation holes 9 together. Then, the dust in the heat dissipation holes 9 is scraped to one side of the housing 1 by the scraping plate 115, completing the treatment of the blocked dust inside the heat dissipation holes 9, preventing the blockage of the heat dissipation holes 9 from affecting the heat dissipation efficiency of the dry-type transformer body 7, resulting in damage to the internal parts of the dry-type transformer body 7, and greatly improving the use effect and reliability of the mining flameproof dry-type transformer.

[0024] Specifically, after the baffle 13 is subjected to pressure, at this time the pressure sensor 12 will detect the pressure, indicating that the housing 1 has been collided. At this time, control the multiple first electric telescopic rods 6 to contract and not contact the clamping plate 5. At this time, the first electric telescopic rods 6 do not play a fixing role on the clamping plate 5, and only the support spring 4 supports the clamping plate 5, and the support spring 4 is used to shock-absorb the dry-type transformer body 7 to prevent the housing 1 from damaging the dry-type transformer body 7 inside the housing 1 when it is collided.

[0025] The operating principle of the present invention is described as follows: In the present invention, when a mining flameproof dry-type transformer needs to be used, first, the staff determines the position of the mining flameproof dry-type transformer on the mine wall. Then, the first motor 1014 is controlled to start, driving the first round rod 102 to rotate. During the rotation of the first round rod 102, the fixed plate 104 will be driven to rotate. After the side wall of the mounting plate 1012 faces the position of the mine wall to be fixed, the first motor 1014 is controlled to stop. Then, the first electric slide rail 105 is controlled to start, driving a plurality of first slide plates 106 to move. After the positions of the plurality of mounting plates 1012 correspond to the position of the mine wall to be installed, the first electric slide rail 105 is controlled to stop. Then, the third motor 1010 is controlled to start, driving the second round rod 109 to rotate, and using the second round rod 109 to drive the third electric telescopic rod 1011 to rotate, so that the inclination angle of the mounting plate 1012 is the same as the inclination angle of the mine wall at the installation location. Then, by controlling the second motor 107 to start, driving the mounting plate 1012 to rotate, so that the mounting plate 1012 can be attached to the mine wall. Then, the third electric telescopic rod 1011 is controlled to start, driving the mounting plate 1012 to move, so that the mounting plate 1012 contacts the corresponding mine wall. Then, the staff installs the mounting bolts 1013 on one side of the mounting plate 1012 into the mine wall to fix the mounting plate 1012 on the mine wall, realizing the installation of the mining flameproof dry-type transformer, facilitating the operation of the mining flameproof dry-type transformer in the mine. By controlling the second electric telescopic rod 103 to start, driving the housing 1 to move outward, so that there is enough space for the heat dissipation holes 9 opened on one side of the housing 1 to dissipate heat from the dry-type transformer. After long-term use, when most of the heat dissipation holes 9 are blocked by dust in the mine, the third electric slide rail 117 is controlled to start, driving the third slide plate 118 to move, so that one end of the push rod 1114 is located on one side of the first row of heat dissipation holes 9. Then, the fourth electric telescopic rod 1121 is controlled to contract, driving the connecting plate 119 to move towards the heat dissipation holes 9, so that the push rod 1114 passes through the inside of the heat dissipation holes 9, thereby pushing the dust blocked in the heat dissipation holes 9 outside the housing 1. Then, the fifth motor 1117 is controlled to start, driving the rotating rod 1118 to rotate. During the rotation of the rotating rod 1118, the connecting block 1119 and the sweeping plate 1120 will be driven to rotate. After the sweeping plate 1120 rotates 90 degrees, the fifth motor 1117 is controlled to stop. At this time, the side wall of the sweeping plate 1120 abuts against the side wall of the housing 1. Then, the fourth motor 1113 is controlled to start, driving the corresponding winch 1110 to rotate. During the rotation of one of the winches 1110, under the transmission of the hinge 1111, the other winches 1110 will follow to rotate. At this time, the push rod 1114 will be driven to rotate, so that the sweeping plate 1120 rotates on the side wall outside the heat dissipation holes 9. After the sweeping plate 1120 rotates 360 degrees, the dust outside the heat dissipation holes 9 will be swept together by the sweeping plate 1120. Then, the sweeping plate 1120 is controlled to return to its original position, and then the fourth electric telescopic rod 1121 is controlled to extend, so that the push rod 1114 re-enters the housing 1.After that, control the third electric slide rail 117 to start, drive the third slide plate 118 to move, so that the push rod 1114 clears the dust blocked inside other heat dissipation holes 9. The dust outside the heat dissipation holes 9 is swept together by the sweeping plate 1120, preventing the dust accumulated outside the heat dissipation holes 9 from re-entering the heat dissipation holes 9 after the subsequent push rod 1114 moves out of the heat dissipation holes 9, resulting in the heat dissipation holes 9 being blocked again and reducing the cleaning effect of the dust inside the heat dissipation holes 9. After all the heat dissipation holes 9 are cleaned, control the push rod 1114 to return to its original position. Then control the second electric slide rail 112 to start, drive the second slide plate 113 to move, so that the side plate 114 drives the scraping plate 115 to move, and use the scraping plate 115 to scrape the dust swept together by the sweeping plate 1120 to one side of the housing 1, completing the cleaning of the dust inside the heat dissipation holes 9, preventing the dust from blocking inside the heat dissipation holes 9 and affecting the heat dissipation of the dry-type transformer body 7. When the mining flameproof dry-type transformer needs to be installed, the position and inclination angle of the mounting plate 1012 can be adjusted according to the inclination angle of the mine wall, so that the mounting plate 1012 can fit the mine wall, facilitating the fixing of the mounting plate 1012 on the mine wall by using the mounting bolts 1013, and completing the installation of the mining flameproof dry-type transformer. This avoids the need for workers to replace corresponding mounting parts according to the inclination angle of the mine wall at the installation position when installing the mining flameproof dry-type transformer, reducing the installation efficiency of the mining flameproof dry-type transformer. At the same time, after the heat dissipation holes 9 are blocked by the dust in the mine, the push rod 1114 and the sweeping plate 1120 can be used to push the dust inside the heat dissipation holes 9 out of the heat dissipation holes 9 and sweep the dust outside the heat dissipation holes 9 together. Then, the scraping plate 115 is used to scrape the dust inside the heat dissipation holes 9 to one side of the housing 1, completing the treatment of the blocked dust inside the heat dissipation holes 9, preventing the heat dissipation holes 9 from being blocked and affecting the heat dissipation efficiency of the dry-type transformer body 7, resulting in damage to the internal parts of the dry-type transformer body 7, and greatly improving the use effect and reliability of the mining flameproof dry-type transformer.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
