Description

Technical Field

[0001] This utility model relates to the field of fan control cabinet technology, and in particular to a redundant control circuit board mounting structure for a sewage treatment plant deodorization fan. Background Technology

[0002] In the deodorization system of a wastewater treatment plant, the blower is a core piece of equipment, and its stable operation is crucial. However, due to various unforeseen factors, such as equipment failure and power outages, the blower may stop operating, thereby affecting the deodorization effect.

[0003] Redundancy control, by adding backup equipment or control systems, ensures that in the event of a failure in the main equipment or control system, the backup equipment or system can quickly take over, guaranteeing the continuous and stable operation of the deodorizing fan. In practical applications, many wastewater treatment plants use redundant control circuit boards to ensure the stable operation of the deodorizing fan. For example, some large wastewater treatment plants may be equipped with multiple deodorizing fans and use redundant control circuit boards to achieve automatic fan switching and fault alarm functions. In this way, even if one fan fails, the other fans can quickly take over the operation, ensuring the normal operation of the deodorization system.

[0004] Redundant control circuit boards have the following drawbacks. Generally, redundant control circuit boards are installed inside the electrical box. However, when subsequent periodic inspections, replacements, and maintenance are required, the narrow and dark interior of the electrical box necessitates personnel to reach into the confined space while simultaneously needing lighting equipment to operate, leading to significant maintenance difficulties and impacting maintenance efficiency. To address these issues, a redundant control circuit board installation structure for a wastewater treatment plant deodorization fan is proposed. Utility Model Content

[0008] As a further description of the above technical solution: a frosted pad is fixedly connected to the outer side wall of the hexagonal plate, and the hexagonal plate is snapped into the inner front wall of the slot.

[0009] As a further description of the above technical solution: the end of the compression spring away from the hexagonal plate is fixedly connected to the inner wall of the front end of the rotating rod, and the outer diameter of the sealing plate is adapted to the size of the inner wall of the right side of the fan casing.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-3 This utility model provides an embodiment of a redundant control circuit board mounting structure for a wastewater treatment plant deodorization fan, comprising a fan housing 1, a fixing plate 2, a mounting bracket 3, and a control circuit board body 4. An adjustment mechanism 5 is provided on the fan housing 1, and an auxiliary mechanism 6 is provided on the adjustment mechanism 5. The adjustment mechanism 5 includes a rotating rod 51, one end of which is rotatably connected to the inner wall of one side of the fan housing 1 via a bearing. A sealing plate 52 is fixedly connected to the rotating rod 51, thereby shielding the inner wall of the right side of the fan housing 1. The inner side wall of the rotating rod 51 is provided with a slide rail 53. The inner walls of the left and right sides of the slide rail 53 are slidably connected with hexagonal plates 54. By setting the hexagonal plates 54 and the slots 56 to cooperate with each other, the rotation of the rotating rod 51 is limited. The outer front wall of the hexagonal plates 54 is fixedly connected with a compression spring 55. The outer front wall of the fan housing 1 is provided with a slot 56. The outer right side wall of the mounting bracket 3 is provided with a groove 57. The inner right side wall of the groove 57 is fixedly connected with a telescopic spring 58. The telescopic spring 58 generates a continuous thrust on the mounting bracket 3.

[0025] Reference Figures 2-4 A frosted pad is fixedly connected to the outer side wall of the hexagonal plate 54. The hexagonal plate 54 is snapped into the inner front wall of the slot 56. The end of the compression spring 55 away from the hexagonal plate 54 is fixedly connected to the inner front wall of the rotating rod 51. The compression spring 55 generates a continuous thrust on the hexagonal plate 54. The outer diameter of the sealing plate 52 is adapted to the size of the inner right side wall of the fan housing 1. The end of the telescopic spring 58 away from the groove 57 is fixedly connected to the inner side wall of the fan housing 1. The inner front wall of the mounting bracket 3 is fixedly connected to the viewing window 59. The viewing window 59 allows personnel to easily see the internal components and monitor their operation. The fixing plate 2 is fixedly connected to the outer rear wall of the fan housing 1. The mounting bracket 3 is slidably connected to the inner right side wall of the fan housing 1. The control circuit board body 4 is fixedly connected to the inner bottom wall of the mounting bracket 3.

[0026] Reference Figures 3-4The auxiliary mechanism 6 includes a bracket 61, which is fixedly connected to the inner front wall of the mounting frame 3. The bracket 61 supports the mounting frame 3. A movable plate 62 is slidably connected to the inner left side of the bracket 61, and a sliding frame 63 is slidably connected to the outer left side of the movable plate 62. The sliding frame 63 and the movable plate 62 cooperate with each other to allow the movable plate 62 to slide vertically up and down. A groove 64 is provided on the inner right side of the fan housing 1. A transverse spring damper 65 is fixedly connected to the inner right side of the bracket 61. The outer bottom wall of the bracket 61 is fixed. A vertical spring damper 66 is connected to the sliding frame 63, which is slidably connected to the bottom inner wall of the slide groove 64. A horizontal spring damper 65 is fixedly connected at one end away from the bracket 61 to the right outer wall of the movable plate 62. The horizontal spring damper 65 is used to buffer and reduce the horizontal vibration force. The vertical spring damper 66 is fixedly connected at one end away from the bracket 61 to the bottom inner wall of the sliding frame 63. The vertical spring damper 66 is used to buffer and reduce the vertical vibration force. A wear-resistant pad is fixedly connected to the bottom inner wall of the slide groove 64.

[0027] Working principle: When it needs to be opened, the hexagonal plate 54 is pulled to separate from the slot 56. Then, the hexagonal plate 54 is rotated to make the rotating rod 51 rotate. The rotation of the rotating rod 51 drives the sealing plate 52 to rotate, so that the sealing plate 52 unfolds against the right outer wall of the fan housing 1. Then, the hexagonal plate 54 is reinserted into the slot 56 to limit the sealing plate 52 and prevent it from rotating downward on its own. Then, under the continuous thrust of the telescopic spring 58, the mounting frame 3 moves a distance outside the fan housing 1, making it convenient for personnel to pull the mounting frame 3 out of the fan housing 1 area, so that personnel can easily maintain and inspect the control circuit board body 4 in an open area. At the same time, when the mounting frame 3 is closed with the fan housing 1, the vibration force generated by the external collision is transmitted to the sliding frame 63, so that the vertical vibration force is transmitted to the vertical spring damper 66 for buffering and shock absorption, and the horizontal vibration force is transmitted to the movable plate 62 to squeeze the horizontal spring damper 65 for buffering and shock absorption, reducing the severe vibration of the circuit equipment on the mounting frame 3.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended 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 described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
