Description

Technical Field

[0001] This utility model belongs to the field of equipment heat dissipation technology, and relates to a heat dissipation device for an oil drilling machinery controller. Background Technology

[0002] In oil drilling operations, the controller is a core component that ensures the normal operation of drilling machinery. However, the controller continuously generates a large amount of heat during operation, making heat dissipation a key factor affecting its performance and lifespan.

[0003] Existing cooling devices for oil drilling machinery controllers rely solely on a single fixed fan to blow air onto the back of the controller during the cooling process. The fan only blows air onto a fixed location on the back of the controller to cool it down, and the outer casing of the controller has only one air outlet for heat dissipation. This results in a limited airflow area for the cooling device, low overall heat dissipation efficiency, and an inability to dissipate the heat generated by the controller in a timely manner. This often leads to excessively high controller temperatures, affecting its normal operation. Summary of the Invention

[0004] The purpose of this invention is to provide a heat dissipation device for an oil drilling machinery controller. This invention improves the heat dissipation air duct of the controller, allowing multiple fans to cool the controller while moving, increasing the air blowing area, accelerating the air flow speed inside the outer casing, and ensuring that the controller operates stably at a suitable temperature.

[0024] The elastic element is perpendicular to the fixing frame and is fixedly installed above or below the socket. One end is fixedly connected to the fixing frame, and the other end is fixedly connected to the card plate through the connecting block.

[0042] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0043] Example 1: A heat dissipation device for an oil drilling machinery controller

[0044] like Figures 1 to 6 As shown, this embodiment is a heat dissipation device for an oil drilling machinery controller. This embodiment includes an outer casing 1 with one open side. A controller 3 is fixedly installed inside the outer casing 1, with the front of the controller 3 facing the opening of the outer casing 1. A door panel 4 is hinged to the opening of the outer casing 1. An air inlet mechanism 6 is provided on the side opposite the opening of the outer casing 1. An air outlet is provided on one of the left or right sides of the outer casing 1. A blower mechanism is provided inside the outer casing 1, between the air inlet mechanism 6 and the controller 3. The back of the controller 3 is fixedly connected to the inside of the outer casing 1 via a fixing plate 5, with both ends of the fixing plate 5 fixedly connected to the left and right end faces inside the outer casing 1, respectively.

[0045] The blower mechanism includes three fans 24 for blowing air onto the back of the controller 3, an arc-shaped frame 25 with a sliding mechanism, and a drive mechanism for controlling the up-and-down movement of the sliding mechanism. The sliding mechanism includes a mounting bracket 22 and upper and lower sliding blocks 23. The three fans 24 are arranged horizontally and fixedly mounted on the upper and lower sliding blocks 23 by the mounting bracket. The upper and lower sliding blocks 23 are slidably mounted on the arc-shaped frame 25. The arc-shaped frame 25 is fixed inside the outer casing 1, and the length extension direction of the arc is consistent with the height extension direction of the controller 3. The bend formed by the arc-shaped frame 25 faces the controller 3.

[0046] Due to space constraints within the outer casing 1, the drive mechanism is located on the side of the arc-shaped frame 25. The drive mechanism includes a drive motor 21, a vertically arranged reciprocating threaded rod 27, a lifting block 29 mounted on the reciprocating threaded rod 27, and a transmission mechanism that transmits power from the lifting block 29 to the upper and lower sliding blocks 23. The transmission mechanism includes a horizontal sliding frame 210 with a horizontal sliding block 28 and an L-shaped control frame 26.

[0047] The drive motor 21 is located on the top of the outer casing 1, and the bottom surface of the output end of the drive motor 21 extends through the top surface of the outer casing 1 into the interior of the outer casing 1. One end of the reciprocating threaded rod 27 is fixedly connected to the output end of the drive motor 21, and the other end is rotatably connected to the bottom surface inside the outer casing 1. One long side of the control frame 26 is hinged to the back of the upper and lower sliding blocks 23, and one short side is fixedly connected to the horizontal sliding block 28 through the connecting rod 211. The horizontal sliding frame 210 is fixedly connected to the lifting block 29. The drive motor 21 drives the reciprocating threaded rod 27 to rotate, causing the lifting block 29 to move up and down on the reciprocating threaded rod 27. As the lifting block 29 rises and falls, it drives the horizontal sliding frame 210 to rise and fall, which in turn drives the control frame 26 to rise and fall. Since the control frame 26 is hinged to the upper and lower sliding blocks 23, it drives the upper and lower sliding blocks 23 to slide up and down on the arc frame 25, which in turn drives the three fans 24 to move up and down.

[0048] To ensure the stroke of the upper and lower sliding blocks 23, the length of the horizontal sliding bracket 210 must be greater than the horizontal sliding distance of the upper and lower sliding blocks 23.

[0049] In this embodiment, an air inlet mechanism 6 is provided to ensure good airflow. The air inlet mechanism 6 includes an air inlet frame 63, a filter plate inserted from the top of the air inlet frame 63, and a fixing device for fixing the filter plate. The fixing device is located at the bottom of the air inlet frame 63.

[0050] The filter insert plate has a filter 62 in the middle, and two ends are divided into an installation end 61 and an insertion end; the side of the insertion end facing away from the controller 3 has a slot 64 for fixing with a fixing device. The top end face of the air inlet frame 63 has a filter insertion port that matches the filter insert plate. Matching here means that the filter insert plate can be inserted through the filter insertion port without any left or right displacement.

[0051] The fixing device includes a fixing frame 68 parallel to the filter insert plate, a clamping plate 65, and an elastic element 67. A clamping plate slot for inserting the clamping plate 65 is provided on the fixing frame 68 at the same horizontal position as the slot 64. To ensure that the clamping plate 65 is always engaged in the slot 64, this embodiment includes an elastic element 67. The elastic element 67 is perpendicular to the fixing frame 68 and fixedly disposed above the slot. One end of the elastic element 67 is fixedly connected to the fixing clamp 68, and the other end is fixedly connected to the clamping plate 65 via a connecting block 66 perpendicular to the clamping plate 65. In this embodiment, the elastic element 67 is always in a stretched state. When the clamping plate 65 is engaged in the slot 64, the tension of the elastic element 67 keeps the clamping plate 65 within the slot 64.

[0052] In this embodiment, the drive motor 21 drives the reciprocating threaded rod 27 to rotate, which in turn drives the lifting block 29 to move up and down. Since the lifting block 29 is fixedly connected to the horizontal sliding frame 210, and the horizontal sliding block 28 on the horizontal sliding frame 210 is fixedly connected to the control frame 26 through the connecting rod 211, the lifting block 29 drives the horizontal sliding frame 210 and the control frame 26 to move up and down together, which in turn drives the upper and lower sliding blocks 23 to move up and down on the arc frame 25. The three fans 24 are fixedly connected to the upper and lower sliding blocks 23 through the mounting bracket 22, so the fans 24 move up and down with the movement of the upper and lower sliding blocks 23, thereby achieving air cooling on the back of the controller 3.

[0053] When outside air enters the outer casing 1, the filter 62 filters impurities in the air, preventing larger impurities from entering the outer casing 1 and affecting the operation of the controller 3. After a period of use, the filter 62 can be disassembled and cleaned. To disassemble, pull out the retaining plate 65 and manually pull upwards the mounting end 61 of the filter insert. To reinstall the filter 62, align the insertion end of the filter insert with the opening, pull out the retaining plate 65, manually push the filter insert through the opening, and finally release the retaining plate 65. The retaining plate 65 will then engage with the slot 64 of the insertion end under the action of the elastic element 67, thus securing the filter 62.

[0054] In summary, this implementation improves the heat dissipation duct of controller 3, allowing multiple fans 24 to cool controller 3 while moving, increasing the air blowing area, accelerating the air flow speed inside the outer casing 1, and ensuring that controller 3 operates stably at a suitable temperature.
