Description

Technical Field

[0001] The utility model relates to the technical field of coal mine electromechanical systems, in particular to a cooling device for coal mine electromechanical systems. Background Art

[0002] Coal mine electromechanical equipment includes two categories: coal mine mechanical equipment and electrical equipment. The functions of these equipment are different, but they all play an important role in coal mine production and management. The equipment that uses motors in coal mines includes belt conveyors, winches, and underground electric locomotives. The distribution of motor cooling fins includes vertical distribution to the shaft, horizontal distribution, and spiral distribution. The commonly used motors in coal mines include flameproof three-phase asynchronous motors and DC motors. Among them, the cooling fins of flameproof three-phase asynchronous motors are horizontally distributed. This type of cooling fins needs to be cleaned manually, and the environment in the coal mine is relatively closed. There is often coal ash floating in the air, and the coal ash will accumulate quickly in the cooling fins of the motor. Some existing coal mine motor cooling devices can accelerate the flow of air outside the motor to assist in heat dissipation by blowing air, but it is not convenient to clean the coal ash in the motor cooling fins. The accumulation of coal ash affects the heat dissipation effect of the motor, resulting in excessive motor temperature, reduced service life, and inconvenient use. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 7 In an embodiment of the utility model, a cooling device for coal mine electromechanical includes a cooling mechanism 10, and the cooling mechanism 10 includes a U-shaped shell 11 and two mounting shells 12. The front side of the U-shaped shell 11 is symmetrically fixed with two docking plates 111, and the rear side of the U-shaped shell 11 is fixed with an exhaust fan 13. One side of the mounting shell 12 is equidistantly rotatably connected with a plurality of cleaning rollers 121 for cleaning the heat dissipation fins on the motor body 20. Two protective shells 14 for protecting adjacent mounting shells 12 are movably clamped on the outer wall of the U-shaped shell 11, and a control module 15 for regulating the two mounting shells 12 is provided on the outer wall of the U-shaped shell 11.

[0024] Specifically, a plurality of cleaning rollers 121 are equidistantly connected to one side of the mounting shell 12, and the protective shell 14 can be disassembled by pulling the pull rod 146. The mounting shell 12 is rotated 180 degrees, and then the mounting shell 12 is pulled to move back and forth laterally. The plurality of cleaning rollers 121 rotate synchronously and move back and forth between the cooling fins of the motor body 20. The deployment is convenient, and the coal ash remaining between the cooling fins of the motor body 20 can be quickly cleaned, thereby ensuring the heat dissipation performance of the motor body 20, extending the service life of the motor body 20, and facilitating use.

[0025] Embodiment 1

[0026] like Figure 3-4 As shown, in this embodiment, the interior of the mounting shell 12 is equidistantly connected to a plurality of shafts 122, one end of the shaft 122 penetrates the mounting shell 12 and is fixedly connected to an adjacent cleaning roller 121, and the other end of the shaft 122 is fixedly sleeved with a gear 123, and two adjacent gears 123 mesh with each other. The control module 15 includes two vertical rods 151 symmetrically connected to the outer wall of the U-shaped shell 11, and two limit rods 152 and an L-shaped block 153 are fixedly connected to the outer wall of the vertical rod 151. The top and bottom ends of the mounting shell 12 are fixedly connected to the ear plates 123. 4. The limiting rod 152 passes through the adjacent ear plate 124 and is slidably connected thereto. A round block 1521 is fixedly connected to one end of the limiting rod 152. A rack 154 is fixedly connected to one end of the L-shaped block 153. The rack 154 passes through the mounting shell 12 and meshes with the adjacent gear 123. Two mounting blocks 155 are symmetrically fixedly connected to the outer wall of the U-shaped shell 11. An insert rod 156 is slidably connected inside the mounting block 155. The insert rod 156 passes through the adjacent vertical rod 151 and is movably engaged therewith. A spring 2 157 is fixedly connected between the insert rod 156 and the mounting block 155.

[0027] In this embodiment, the sliding limit of the cleaning roller 121 is achieved by limiting the shaft rod 122 by the mounting shell 12, and the engagement of multiple gears 123 enables multiple cleaning rollers 121 to be synchronously driven, and the rotation directions of two adjacent cleaning rollers 121 are opposite. The mounting shell 12 is slidingly limited by the cooperation of two limiting rods 152, and the rotation limit of the vertical rod 151 enables the mounting shell 12 to be rotated and stored near the outer wall of the U-shaped shell 11, and protected by the protective shell 14, and can also be rotated to the vicinity of the motor body 20 to clean the heat dissipating fins thereon. The mounting shell 12 is pushed to move on the limiting rod 152 by holding the mounting shell 12, and the adjacent cleaning rollers 121 are driven to rotate by the transmission of the rack 154 and the adjacent gears 123. The plurality of cleaning rollers 121 are driven to rotate through the transmission between the plurality of gears 123. At the same time, the plurality of cleaning rollers 121 are staggered with the heat dissipation fins of the motor body 20 and move between the heat dissipation fins. The setting of the round block 1521 can prevent the mounting shell 12 from being separated from the limiting rod 152. The mounting block 155 performs sliding limit on the insertion rod 156. The insertion rod 156 can be limited by being stuck into the inside of the vertical rod 151. The mounting shell 12 can be positioned separately in two states, namely, when it is stored and exposed. This makes the mounting shell 12 more stable when it is stored and exposed for cleaning. The limit can be released by manually pulling the insertion rod 156 and the vertical rod 151. The spring 2 157 can prevent the insertion rod 156 from separating from the vertical rod 151 by itself.

[0028] like Figure 7 As shown, in this embodiment, a positioning plate 112 is fixedly connected to the bottom of the docking plate 111 .

[0029] In specific implementation, when the U-shaped shell 11 and the motor body 20 are connected, the docking plate 111 is aligned with the bolt hole on the base of the motor body 20, and the two positioning plates 112 are respectively and movably connected to the outside of the adjacent motor body 20 bases, so that the docking plate 111 can be more conveniently aligned, and the bolts are passed through the docking plate 111 and the base of the motor body 20 to fix them. The docking plate 111 and the positioning plate 112 need to be produced according to the specific model of the motor body 20 and the specific size of the mounting base.

[0030] Embodiment 2

[0031] On the basis of the first embodiment, in order to be able to protect the installation shell 12 when it is stored, to prevent accidental touch from causing damage to the installation shell 12 and the cleaning roller 121.

[0032] like Figure 5-6 As shown, in this embodiment, two mounting rods 142 are symmetrically fixedly connected to the outer wall of the U-shaped shell 11, the protective shell 14 is movably engaged with the adjacent mounting rods 142, a docking block 141 is fixedly connected to the bottom of the protective shell 14, a slot 143 is provided on the top of the mounting rod 142, the docking block 141 is movably engaged with the adjacent slot 143, an insert block 144 is slidably connected between an inner wall of the slot 143, one end of the insert block 144 is arc-shaped, and the arc-shaped end of the insert block 144 can be movably engaged with the docking block 141, a spring 145 is fixedly connected between the insert block 144 and the mounting rod 142, a pull rod 146 is fixedly connected to the front side of the insert block 144, and the pull rod 146 passes through the mounting rod 142 and is slidably connected thereto.

[0033] During specific implementation, after the mounting shell 12 is rotated and stored against the outer wall of the U-shaped shell 11, the protective shell 14 is aligned with the mounting rod 142 and then slid into place, which is convenient for preliminary positioning of the protective shell 14 as a whole. When the protective shell 14 is docked with the mounting rod 142, the docking block 141 slides into the inside of the slot 143, and the docking block 141 moves the arc-shaped end of the plug block 144 so that the plug block 144 moves between the inner walls of the slot 143 to compress the spring 145. After the docking block 141 moves to the deepest part of the slot 143, the spring 145 drives the plug block 144 to slide and reset and be stuck into the inside of the docking block 141 to limit the docking block 141. Subsequently, the pull rod 146 can be pulled from the outside to drive the plug block 144 to separate from the docking block 141 and release the limit.

[0034] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0035] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
