Description

Technical Field

[0001] This utility model belongs to the technical field of compressor control devices, and in particular relates to an automated control device applied to CNG compressors. Background Technology

[0002] CNG, or compressed natural gas, is a clean, efficient, and safe high-quality energy source that occupies an increasingly important position in the energy structure. It is mainly composed of methane and has advantages such as complete combustion, low pollution, and relatively low price. It is widely used in urban public transportation, taxis, logistics transportation and other fields, and has become an important alternative energy source to traditional fuel oil. It is of great significance for improving urban air quality and reducing dependence on oil resources.

[0003] In the operating environment of CNG compressor-related equipment, air filtration in the control cabinet is crucial, directly affecting the stability and service life of the equipment. However, existing air filtration technologies for CNG compressor control cabinets have significant shortcomings. They lack flexibility in air filtration, and in practical applications, air quality varies greatly in different regions and at different times, with significant fluctuations in the content of impurities in the air. Most existing air filtration devices use a single filtration method, which is insufficient to effectively intercept all impurities. The efficiency of a single-layer filtration decreases significantly as the amount of impurities increases, allowing a large amount of dust and other impurities to enter the main body of the control cabinet. These impurities adhere to the surface of electrical equipment, affecting the heat dissipation performance of the equipment, accelerating equipment aging, and may even cause short circuits and other malfunctions, seriously threatening the safe and stable operation of the CNG compressor control cabinet. Utility Model Content

By setting up an air filtration mechanism and a drive mechanism, it solves the problem in existing technologies where air quality varies greatly in different regions and at different times, and the content of impurities in the air fluctuates significantly. However, most existing air filtration devices use a single filtration method, and a single filtration structure is difficult to effectively intercept all impurities. The efficiency of a single-layer filtration decreases significantly as the amount of impurities increases, allowing a large amount of dust and other impurities to enter the control cabinet. These impurities adhere to the surface of electrical equipment, affecting the heat dissipation performance of the equipment, accelerating equipment aging, and may even cause short circuits and other faults, seriously threatening the safe and stable operation of the CNG compressor control cabinet.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is an automated control device applied to a CNG compressor, including a control cabinet body; a cabinet door is hinged to the outer side wall of the control cabinet body, and a touch screen is fixedly connected to the outer side wall of the cabinet door; an air filter mechanism for filtering gas is provided at the top of the control cabinet body, and a drive mechanism for driving the air filter mechanism to perform circular motion is provided on one side of the air filter mechanism at the top of the control cabinet body.

[0006] The present invention is further configured such that an air exchange fan is fixedly connected to the inner top of the control cabinet body directly below the air filter mechanism, and the air blowing direction of the air exchange fan is located inside the control cabinet body. A conical air collection hood is embedded inside the control cabinet body above the air exchange fan, and the end of the air collection hood away from the air exchange fan is located at the top of the control cabinet body. A connecting pipe is fixedly connected to the end of the air collection hood away from the air exchange fan.

[0007] The present invention is further configured such that the air filtration mechanism includes six fixed brackets fixedly connected to the top of the control cabinet body, an upper cover plate fixedly connected to the bottom of the six fixed brackets, a placement frame fixedly connected to the bottom of the upper cover plate, a lower cover plate rotatably sleeved to the bottom of the placement frame, and a sleeve rotatably sleeved to the outer wall of the connecting pipe fixedly connected to the bottom of the lower cover plate.

[0008] The present invention is further configured such that six rotating parts are fixedly connected to the top end of the sleeve in a ring array, two positioning collars are symmetrically fixedly connected to the outer side wall of the placement frame, the six rotating parts at the top end of the lower cover plate are rotatably sleeved inside the positioning collars, and the bottom end of the upper cover plate is located inside the placement frame and is respectively fixedly connected to a first connecting ring and a second connecting ring.

[0009] The present invention is further configured such that a first non-woven filter cloth for filtering air is fixedly connected between the first connecting ring and the second connecting ring; a positioning plate is fixedly connected between the second connecting ring and the placement frame; a rotating plate is rotatably sleeved between the second connecting ring and the placement frame; a second non-woven filter cloth is fixedly connected to the side of the rotating plate away from the positioning plate; and the other end of the second non-woven filter cloth is fixedly connected to the end of the positioning plate away from the rotating plate; the lower bottom end of the rotating plate is fixedly connected to the lower cover plate; and the top end of the rotating plate is rotatably connected to the lower bottom end of the upper cover plate.

[0010] The present invention is further configured such that both the first connecting ring and the second connecting ring are rotatably connected to the lower cover plate, and the interior of the first connecting ring is connected to the interior of the gas collecting hood through a connecting pipe.

[0012] This utility model has the following beneficial effects: 1. This utility model, by setting a first non-woven filter cloth and a positioning plate, allows for different usage environments. When there are few impurities in the air, only the first non-woven filter cloth can be used, thereby accelerating the air filtration efficiency. When there are many impurities in the air, double filtration can be performed through the positioning plate. This method can achieve different environments for the use of the air filtration mechanism, ensuring the purity of the filtered air during use and avoiding the reduction of single-layer filtration efficiency, which would lead to more dust inside the control cabinet.

The first gear meshes with the second gear and drives the sleeve and the lower cover plate to rotate. The lower cover plate drives the rotating plate and the second non-woven filter cloth connected to it to perform circumferential motion. At this time, the second non-woven filter cloth gradually unfolds from the stored folded state, and the positioning plate gradually contacts the rotating plate, thereby completing the unfolding of the positioning plate.

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 - Figure 5 As shown, an automated control device for a CNG compressor includes a control cabinet body 1; a cabinet door 2 is hinged to the outer side wall of the control cabinet body 1, a touch screen display 3 is fixedly connected to the outer side wall of the cabinet door 2, an air filter mechanism 5 for filtering gas is provided at the top of the control cabinet body 1, and a drive mechanism 4 for driving the air filter mechanism 5 to perform circular motion is provided on one side of the air filter mechanism 5 at the top of the control cabinet body 1.

[0019] It should be noted that the cabinet door 2 is hinged to the outside of the main body 1 of the control cabinet for easy opening and closing. A touch screen display 3 is fixed on the cabinet door 2, which allows operators to intuitively and conveniently input commands and view data, enabling real-time monitoring and precise control of the CNG compressor's operating status, thereby improving operational efficiency and accuracy. The air filter mechanism 5 set at the top of the main body 1 of the control cabinet can effectively filter the air entering the control cabinet, removing dust, impurities and other harmful substances, preventing them from entering the control cabinet and damaging electronic components, providing a clean working environment for all components inside the control cabinet, extending the service life of the equipment, and ensuring the stable operation of the automated control device.

[0020] In an optional embodiment, an air exchange fan 6 is fixedly connected to the inner top of the control cabinet body 1, directly below the air filter mechanism 5, and the air blowing direction of the air exchange fan 6 is inside the control cabinet body 1. A conical air collection hood 7 is embedded inside the control cabinet body 1 above the air exchange fan 6, and the end of the air collection hood 7 away from the air exchange fan 6 is located at the top of the control cabinet body 1. A connecting pipe 8 is fixedly connected to the end of the air collection hood 7 away from the air exchange fan 6.

[0021] It should be noted that the air exchange fan 6 installed inside the control cabinet body 1 is located directly below the air filter mechanism 5, and the air blowing direction is towards the inside of the control cabinet. This design can accelerate the air flow inside the control cabinet, form an effective airflow circulation, and promptly remove the heat generated by the electronic components inside the cabinet, enhance the heat dissipation effect, avoid the performance degradation or damage of components due to high temperature, and ensure the stable operation of the automated control device. The conical air collection hood 7 is embedded inside the control cabinet body 1 and above the air exchange fan 6, guiding the concentrated flow of external air.

[0022] In an optional embodiment, the air filtration mechanism 5 includes six fixed brackets 51 fixedly connected to the top of the control cabinet body 1. The bottom ends of the six fixed brackets 51 are fixedly connected to an upper cover plate 53. The bottom ends of the upper cover plate 53 are fixedly connected to a placement frame 52. The bottom ends of the placement frame 52 are rotatably sleeved with a lower cover plate 54. The bottom ends of the lower cover plate 54 are fixedly connected to a sleeve 55 rotatably sleeved on the outer wall of the connecting pipe 8. The top end of the sleeve 55 is fixedly connected to six rotating parts 531 in a circular array. The outer side wall of the placement frame 52 is symmetrically fixedly connected to two positioning collars 56. The six rotating parts 531 at the top of the lower cover plate 54 are rotatably sleeved inside the positioning collars 56. The bottom ends of the upper cover plate 53 are located inside the placement frame 52 and are respectively fixedly connected to a first connecting ring 57 and a second connecting ring 58.

[0023] It should be noted that the six fixed brackets 51 firmly support the upper cover plate 53 on the top of the control cabinet body 1, providing a stable foundation for the entire filtration mechanism, ensuring that it will not shake or shift during operation, and guaranteeing the continuous stability of filtration work. The combination of the placement frame 52, the upper cover plate 53, and the lower cover plate 54 forms a flexibly openable filtration space. The lower cover plate 54 is rotatably sleeved on the bottom end of the placement frame 52. With the help of the six rotating parts 531 and the positioning collar 56, the lower cover plate 54 can rotate smoothly. The first connecting ring 57 and the second connecting ring 58 at the bottom end of the upper cover plate 53 can be used to fix different types or layers of filter materials, enhance filtration efficiency, effectively filter dust, impurities, etc. in the air entering the control cabinet, provide a clean working environment for the electronic components in the control cabinet, reduce the risk of damage to components due to dust accumulation, and extend the service life of the equipment.

[0024] In an optional embodiment, a first non-woven filter cloth 59 for filtering air is fixedly connected between the first connecting ring 57 and the second connecting ring 58. A positioning plate 591 is fixedly connected between the second connecting ring 58 and the placement frame 52. A rotating plate 592 is rotatably sleeved between the second connecting ring 58 and the placement frame 52. A second non-woven filter cloth 593 is fixedly connected to the side of the rotating plate 592 away from the positioning plate 591, and the other end of the second non-woven filter cloth 593 is fixedly connected to the end of the positioning plate 591 away from the rotating plate 592. The bottom end of the rotating plate 592 is fixedly connected to the bottom cover plate 54, and the top end of the rotating plate 592 is rotatably connected to the bottom end of the top cover plate 53. Both the first connecting ring 57 and the second connecting ring 58 are rotatably connected to the bottom cover plate 54. The interior of the first connecting ring 57 is connected to the interior of the air collection hood 7 through a connecting pipe 8.

[0025] It should be noted that the first non-woven filter cloth 59 placed between the first connecting ring 57 and the second connecting ring 58 can perform preliminary filtration of the air entering the control cabinet, effectively intercepting larger dust and impurities, thus reducing the burden on subsequent fine filtration. The positioning plate 591 and the rotating plate 592 are cleverly matched. The rotating plate 592 can rotate flexibly, and the second non-woven filter cloth 593 fixed on it is connected to the positioning plate 591. When the rotating plate 592 rotates, it can change the filtration area and angle of the second non-woven filter cloth 593, enhancing the filtration of different particles. The filtration capacity for dust particles is further improved, enhancing filtration efficiency. The rotating plate 592 is rotatably connected to the upper and lower cover plates 54, and the first and second connecting rings are also rotatably connected to the lower cover plate 54. This allows for easy opening of the lower cover plate 54 when needed to replace or clean the first non-woven filter cloth 59 and the second non-woven filter cloth 593. The operation is simple and quick. Moreover, the first connecting ring 57 communicates with the inside of the air collection hood 7 through the connecting pipe 8, ensuring that the filtered air can smoothly enter the air collection hood 7 and be discharged, forming a complete air circulation path and providing clean air to the control cabinet.

[0026] In an optional embodiment, the drive mechanism 4 includes a protective cover 43 fixedly connected to the top of the control cabinet body 1. A first gear 44 and a second gear 45 are rotatably sleeved inside the protective cover 43, and the first gear 44 and the second gear 45 mesh and drive each other. A drive motor 41 is fixedly connected to the top of the protective cover 43. A drive rod 42 is fixedly connected to the output end of the drive motor 41, and the end of the drive rod 42 extends into the interior of the protective cover 43 and is fixedly connected to the center of the first gear 44. A sleeve 55 is located inside the protective cover 43 and is rotatably sleeved with the protective cover 43. The second gear 45 is fixedly sleeved on the outer wall of the sleeve 55.

[0027] It should be noted that the protective cover 43 properly protects the internal components such as the first gear 44 and the second gear 45, effectively preventing dust and debris from entering and avoiding wear and jamming of the gears due to foreign object interference. This ensures the stability and reliability of the transmission system and extends its service life. The drive motor 41 drives the first gear 44 to rotate through the drive rod 42. Since the first gear 44 meshes with the second gear 45, it drives the second gear 45 to rotate. The second gear 45 is fixedly sleeved on the outer wall of the sleeve 55, causing the sleeve 55 to rotate accordingly. Ultimately, this drives the air filtration mechanism 5 to make a circular motion. The sleeve 55 is located inside the protective cover 43 and rotates and sleeves with it. This ensures the flexibility of the sleeve 55's rotation and also provides a certain degree of support and limitation through the protective cover 43, reducing the shaking of the sleeve 55 during rotation and further improving the stability of the air filtration mechanism 5's movement. This enhances the air filtration efficiency and provides a cleaner air environment for the control cabinet.

[0028] Working principle: The air exchange fan 6 blows air into the control cabinet body 1 to form an airflow. At this time, the air filtration mechanism 5 plays a filtering role. When there are few air impurities, the first non-woven filter cloth 59 placed between the first connecting ring 57 and the second connecting ring 58 is used to filter the incoming air, which speeds up the air filtration efficiency and ensures that the air entering the control cabinet is relatively clean. When there are too many impurities in the air, the drive mechanism 4 starts to work. The drive motor 41 drives the drive rod 42 and the first gear 44 to rotate. Because the first gear 44 meshes with the second gear 45, the second gear 45 rotates accordingly. Since the second gear 45 is fixedly sleeved on the outer wall of the sleeve 55, the rotation of the sleeve 55 drives the lower cover plate 54 to rotate. The lower cover plate 54 drives the rotating plate 592 and the second non-woven filter cloth 593 to make a circular motion. The second non-woven filter cloth 593 gradually unfolds from the folded state. The positioning plate 591 and the rotating plate 592 cooperate to achieve double filtration. The filtered air enters the air collection hood 7 through the first connecting ring 57 and the connecting pipe 8 and is discharged. This device can flexibly adjust the filtration mode according to different environments to ensure that the filtered air is pure, reduce dust inside the control cabinet body 1, and ensure stable operation of the equipment.
