[0001] This utility model relates to the field of load regulation technology, specifically a centralized control load regulation device. Background Technology

[0002] Centralized control operation is the core control system of modern thermal power plants. It achieves a high degree of automated management of the units through a distributed control system. This system has the characteristics of real-time monitoring, efficient data processing and high safety. It is widely used in large and medium-sized thermal power plants. Centralized control operation technology not only involves automated control, remote monitoring and data acquisition, but also needs to solve problems such as external environment, steam temperature control and main steam pressure coordination.

[0003] Currently, in actual production at thermal power plants, the fuel used in boilers needs to be adjusted according to gas demand, and the air volume also needs to be adjusted to rationally distribute the boiler load. However, the blowers that currently deliver air volume are only controlled by on / off switches, which is impractical and cannot effectively control the air intake. This can lead to excessively large or small air intakes, affecting fuel combustion efficiency and causing incomplete or excessively rapid combustion.

[0004] Based on this, a centralized control load regulation device is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a centralized control operation load adjustment device, which has the advantages of easy air volume adjustment and solves the problem of ineffective control of air intake, which leads to excessive or insufficient air intake and affects fuel combustion efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a centralized control operation load adjustment device, including a duct, one end of which is connected to a blower, a fixed box is fixedly installed on the top of the duct, and an adjustment mechanism is provided between the fixed box and the duct.

[0007] The adjustment mechanism includes multiple air guide plates movably installed inside the air duct and an electric push rod fixedly installed on the top of the fixed box. An installation plate is fixedly installed on the output shaft of the electric push rod. A connecting block extending into the fixed box is fixedly connected to one side of the installation plate. A connecting plate is fixedly connected to the lower end of the connecting block. Multiple transmission racks are fixedly installed on the outer wall of the connecting plate. A gear connected to the air guide plate is meshed on the outer side of each transmission rack.

[0008] Furthermore, the upper side of the fixing box has an opening, which is strip-shaped, and the connecting block passes through the inner side of the opening.

[0009] Furthermore, a guide rail is fixedly installed inside the fixing box, and a slider is fixedly connected to the bottom of the connecting plate, with the slider slidably connected to the inner side of the guide rail.

[0010] Furthermore, a connecting shaft is fixedly connected to the upper end of the air guide plate, the connecting shaft is rotatably connected to the inside of the air duct, and the upper end of the connecting shaft is fixedly connected to a gear.

[0011] Furthermore, a rotating shaft is fixedly connected to the lower end of the air guide plate, and the lower end of the rotating shaft is rotatably connected to the inside of the air duct.

[0012] Furthermore, an installation frame is inserted into the inside of the air duct, and a filter screen is provided on the inner side of the installation frame.

[0013] Furthermore, a connecting ring is fixedly connected to the top of the mounting frame, and an insertion port adapted to the mounting frame is opened on the top of the air duct.

[0014] Compared with the prior art, the present invention provides a centralized control load regulating device, which has the following beneficial effects:

[0015] 1. This centralized control load adjustment device can move the mounting plate via an electric push rod. The mounting plate then moves the connecting block along the inner side of the movable opening. When the connecting block moves, it can move the connecting plate synchronously.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Please see Figures 1 to 4 This embodiment of a centralized control operation load adjustment device includes a duct 1, one end of which is connected to a blower 2. A fixed box 3 is fixedly installed on the top of the duct 1. An adjustment mechanism is provided between the fixed box 3 and the duct 1. The adjustment mechanism includes multiple air guide plates 4 movably installed inside the duct 1 and an electric push rod 5 fixedly installed on the top of the fixed box 3. An installation plate 6 is fixedly installed on the output shaft of the electric push rod 5. A connecting block 7 extending into the fixed box 3 is fixedly connected to one side of the installation plate 6. A connecting plate 8 is fixedly connected to the lower end of the connecting block 7. Multiple transmission racks 9 are fixedly installed on the outer wall of the connecting plate 8. A gear 10 connected to the air guide plate 4 is meshed on the outer side of each transmission rack 9.

[0024] The upper end of the air guide plate 4 is fixedly connected to the connecting shaft 11, which is rotatably connected to the inside of the air duct 1. The upper end of the connecting shaft 11 is fixedly connected to the gear 10. The lower end of the air guide plate 4 is fixedly connected to the rotating shaft, which is rotatably connected to the inside of the air duct 1, so that the air guide plate 4 can rotate. When the transmission rack 9 moves, it can drive the gear 10 to rotate, thereby driving the air guide plate 4 to rotate, so as to adjust the angle of the air guide plate 4, change the air volume inside the air duct 1, and thus adjust the air volume.

[0025] In this embodiment, there are three air guide plates 4, three transmission racks 9, and three gears 10. In other embodiments, there may be four or five air guide plates 4, three transmission racks 9, and three gears 10. When the connecting plate 8 moves, it can drive multiple transmission racks 9 to move synchronously, thereby driving multiple gears 10 to rotate synchronously, thereby synchronously adjusting multiple air guide plates 4.

[0026] The upper side of the fixed box 3 has an opening 17, which is strip-shaped. The connecting block 7 passes through the inner side of the opening 17. The opening 17 facilitates the adjustment of the position of the connecting block 7. The electric push rod 5 drives the mounting plate 6 to move, and the mounting plate 6 drives the connecting block 7 to move along the inner side of the opening 17.

[0027] It should be noted that a guide rail 13 is fixedly installed inside the fixed box 3, and a slider 12 is fixedly connected to the bottom of the connecting plate 8. The slider 12 is slidably connected to the inner side of the guide rail 13. When the connecting block 7 moves, it can drive the connecting plate 8 to move synchronously. The connecting plate 8 will then drive the slider 12 to slide along the inner side of the guide rail 13. The cooperation between the slider 12 and the guide rail 13 guides the connecting plate 8, which improves the stability of the structure.

[0028] In this embodiment, an installation frame 14 is inserted into the inside of the air duct 1. A filter screen 15 is provided on the inner side of the installation frame 14. The filter screen 15 is used to filter impurities in the air to ensure the cleanliness of the airflow. A connecting ring 16 is fixedly connected to the top of the installation frame 14. The connecting ring 16 makes it easy to pick up the installation frame 14. The top of the air duct 1 has an insertion port 18 that matches the installation frame 14 for easy assembly.

[0029] The working principle of the above embodiments is as follows:

[0030] In use, the end of the duct 1 furthest from the blower 2 is connected to the boiler air inlet. The blower 2 supplies air to the boiler through the duct 1. The electric push rod 5 can drive the mounting plate 6 to move, which in turn drives the connecting block 7 to move along the inner side of the movable opening 17. When the connecting block 7 moves, it can drive the connecting plate 8 to move synchronously. The connecting plate 8 can drive the slider 12 to slide along the inner side of the guide rail 13, and at the same time drive the transmission rack 9 to move. When the transmission rack 9 moves, it can drive the gear 10 to rotate, thereby driving the air guide plate 4 to rotate, thus adjusting the angle of the air guide plate 4, changing the air volume inside the duct 1, and thus achieving air volume regulation.

[0031] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
