Description

Technical Field

[0001] The invention belongs to the technical field of excitation control cabinets, and in particular relates to an intelligent excitation control cabinet with automatic operation. Background Art

[0002] The intelligent excitation control cabinet is a key intelligent device in the power system. It integrates advanced excitation regulators, power modules, demagnetization systems and other components. It is designed for generators to establish stable voltage and optimize the power generation process. As the core (CPU) of the electrical system, the intelligent excitation control cabinet is not only responsible for monitoring and controlling the excitation system of the generator, but also has a variety of advanced functions, such as voltage stabilization, constant current, constant power factor regulation, etc., to ensure that the generator can operate efficiently and stably under various working conditions.

[0003] According to the search, the patent document with publication number CN216313756U discloses an automatically operated intelligent excitation control cabinet, including a shell, one side of the shell is rotatably connected to a cabinet door by a hinge, the top of the shell is provided with a ventilation groove running through the top of the shell, the middle part of the inner cavity of the shell is fixedly connected with a ventilation plate, the inner cavity of the shell and directly below the ventilation plate is fixedly connected with a mounting frame, a servo motor is arranged at the center of the inner cavity of the mounting frame, and both sides of the servo motor are fixedly connected to the two inner side walls of the mounting frame by support rods, the output end of the servo motor is transmission-connected with fan blades, the inner cavity of the mounting frame and directly below the fan blades is fixedly connected with a fixing frame, and the top of the fixing frame is provided with a connecting groove running through the fixing frame.

[0004] The existing intelligent excitation control cabinet that can be automatically operated still has the following shortcomings when in use:

[0005] 1. When the existing intelligent excitation control cabinet is in use, there are a large number of electronic components on the inner wall of the control cabinet. In order to ensure the normal operation of the generator excitation system, it is necessary to ensure the normal operation of the electronic components in the control cabinet. Since the interior of the general control cabinet is relatively closed when it is in use, the electronic components in the control cabinet will generate a lot of heat after working for a long time. The existing control cabinet lacks effective heat dissipation means;

[0006] 2. The existing intelligent excitation control cabinet mainly dissipates heat inside the cabinet through the cooling fan installed on the cabinet body. This cooling method is relatively inefficient and will make it easier for dust to accumulate inside the cabinet, affecting the normal use of the control cabinet and increasing the later maintenance cost of the control cabinet.

[0007] 3. When using the existing intelligent excitation control cabinet, the diversity of the control cabinet placement environment is not taken into account. Various electronic components in the control cabinet are extremely sensitive to humid environments. The electronic components in the control cabinet in a humid environment will be corroded and damaged with a high probability in a very short time, which greatly affects the normal use of the control cabinet. The existing device lacks monitoring and alarm mechanisms for humid environments, which challenges the safety of the control cabinet. Summary of the invention

[0012] Preferably, the cooling mechanism includes a conical air guide tube, a connecting pipe, a heat dissipation chamber and a condensing heat dissipation device, the conical air guide tube is connected to the vent, the connecting pipe is connected to the end of the conical air guide tube away from the vent, the heat dissipation chamber is fixedly connected to one side of the control cabinet body, the end of the connecting pipe away from the conical air guide tube is connected to the heat dissipation chamber, and two groups of condensing heat dissipation devices are arranged on one side of the heat dissipation chamber.

[0013] Preferably, the control cabinet body is rotatably connected to a follower disc on one side close to the heat dissipation chamber, the driven bevel gear shaft passes through the linkage housing and the control cabinet body and is coaxially fixedly connected to the follower disc, and the follower disc is rotatably connected to a driving shaft away from the axis position.

[0021] 3. The present invention sets a moisture-proof alarm mechanism, adds silica sol water-absorbing material in the detection box, and utilizes the property of silica sol that is extremely sensitive to moisture to absorb water vapor that may exist in the control cabinet. When the moisture content of the air in the control cabinet is high, the overall quality of the silica sol will be greatly improved due to water absorption, thereby greatly improving the overall gravity of the detection box. Then the telescopic rod and the reset spring will be compressed, so that the detection box squeezes the button switch, thereby causing the alarm bell to be pneumatically activated, thereby reminding the staff to make timely adjustments to avoid further losses.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Reference Figure 1-Figure 6 An intelligent excitation control cabinet for automatic operation includes a control cabinet body 1, a cabinet door 2 is hingedly provided on one side of the control cabinet body 1, a servo motor 3 is fixedly connected to one side of the control cabinet body 1, a vent 4 is provided on the side of the control cabinet body 1 away from the servo motor 3, a bracket 28 is provided in the vent 4, an air supply blade 5 is rotatably connected to the bracket 28, a cooling mechanism 29 is provided on one side of the control cabinet body 1, and a linkage mechanism 30 is provided on the inner wall of the control cabinet body 1 on the side close to the servo motor 3;

[0032] Specifically, the control cabinet body 1 can be opened and closed by manually rotating the cabinet door 2, and the air supply blades 5 can quickly replace the air in the control cabinet body 1;

[0033] Two sets of connecting plates 6 are fixedly connected in the control cabinet body 1, a moisture-proof alarm mechanism 31 is arranged at the inner bottom of the control cabinet body 1, and an alarm bell 7 is arranged at the top of the control cabinet body 1;

[0034] Specifically, various electronic components can be installed on the connecting plate 6, and the alarm bell 7 can sound an alarm after being powered on;

[0035] The linkage mechanism 30 includes a linkage housing 8, a drive shaft 9, a driving bevel gear 10 and a driven bevel gear 11. The linkage housing 8 is arranged in the control cabinet body 1. The drive shaft 9 passes through the bracket 28 and is coaxially fixedly connected to the air supply blade 5. The drive shaft 9 passes through the linkage housing 8 and is rotatably connected thereto. The driving bevel gear 10 and the driven bevel gear 11 are both rotatably connected to the inner wall of the linkage housing 8. The drive shaft 9 is coaxially fixedly connected to the driving bevel gear 10. The output end of the servo motor 3 passes through the control cabinet body 1 and the linkage housing 8 and is coaxially fixedly connected to the driving bevel gear 10. The driving bevel gear 10 and the driven bevel gear 11 are meshed with each other.

[0036] Specifically, the servo motor 3 can drive the driving shaft 9 coaxially fixedly connected to its output end to rotate, so that the active bevel gear 10 coaxially fixedly connected to the driving shaft 9 and located in the linkage housing 8 can rotate. When the active bevel gear 10 rotates, the driven bevel gear 11 meshing therewith can rotate. When the driving shaft 9 rotates, it will drive the air supply blade 5 to rotate. By setting the servo motor 3, the linkage mechanism 30 can be driven by the bevel gear while driving the air supply blade 5, which greatly improves the linkage of the device, making the overall structure of the device more compact, and improving functionality and practicality.

[0037] The cooling mechanism 29 includes a conical air duct 12, a connecting pipe 13, a heat dissipation chamber 14 and a condensation heat dissipation device 15. The conical air duct 12 is connected to the vent 4, the connecting pipe 13 is connected to the end of the conical air duct 12 away from the vent 4, the heat dissipation chamber 14 is fixedly connected to one side of the control cabinet body 1, the end of the connecting pipe 13 away from the conical air duct 12 is connected to the heat dissipation chamber 14, two sets of condensation heat dissipation devices 15 are arranged on one side of the heat dissipation chamber 14, and the control cabinet body 1 is close to the heat dissipation chamber 14. A follower disc 16 is rotatably connected to one side of the chamber 14, the rotating shaft of the driven bevel gear 11 passes through the linkage housing 8 and the control cabinet body 1 and is coaxially fixedly connected to the follower disc 16, the follower disc 16 is rotatably connected to the driving shaft 17 away from the axis position, a piston plate 18 is slidably connected in the heat dissipation chamber 14, the piston plate 18 is slidably connected to the condensation heat dissipation device 15, a rotating seat 19 is fixedly connected to the piston plate 18, and the end of the driving shaft 17 away from the follower disc 16 is rotatably connected to the rotating seat 19;

[0038] Specifically, through the linkage of the linkage mechanism 30, the follower disc 16 will rotate with the rotation of the driven bevel gear 11. When the follower disc 16 rotates, the driving shaft 17 connected to the follower disc 16 away from the axis position can drive the piston plate 18 to reciprocate, and the pressure in the heat dissipation chamber 14 can be continuously changed. When the piston plate 18 slides to one side of the follower disc 16, the hot air in the control cabinet body 1 will be sucked into the heat dissipation chamber 14 through the connection of the connecting pipe 13 and the conical air guide 12, and the initial heat dissipation can be performed on it through the condensation heat dissipation device 15. When the piston plate 18 moves away from the follower disc 16, the air in the heat dissipation chamber 14 will be pressed out. Due to the special design of the connecting pipe 13 and the principle of gas throttling expansion, when the radius of the gas flow channel is reduced, the gas flow rate will be increased, and the gas temperature will drop accordingly. This will cause the air to be cooled twice. The air that has been cooled twice will be introduced into the control cabinet body 1, thus completing the control of the air temperature in the control cabinet body 1, thereby ensuring the normal working environment of the electronic components in each part of the control cabinet body 1.

[0039] The moisture-proof alarm mechanism 31 includes a detection housing 20, an L-shaped fixing plate 21, a support column 22 and a button switch 23. The detection housing 20 is fixedly connected to the bottom of the control cabinet body 1, and the two L-shaped fixing plates 21 are fixedly connected to the top of the detection housing 20. The support column 22 is fixedly connected to the bottom of the detection housing 20. The button switch 23 is fixedly connected to the top of the support column 22. A reset spring 24 and a telescopic rod 25 are fixedly connected to the L-shaped fixing plate 21. The telescopic rod 25 is sleeved in the reset spring 24. The tops of the two reset springs 24 and the two telescopic rods 25 are fixedly connected with a detection box 26. The detection box 26 is provided with a plurality of through holes 27. The button switch 23 is electrically connected to the alarm bell 7.

[0040] Specifically, the moisture-proof alarm mechanism 31 can detect and alarm the humidity in the control cabinet body 1. First of all, it should be noted that silica sol particles are placed in the detection box 26, and a plurality of small holes are provided at the bottom of the detection box 26. When the humidity in the control cabinet body 1 is too high, moisture enters the detection box 26 through the small holes, and the silica sol particles absorb moisture and expand. At this time, the weight of the silica sol particles is increased, and the overall gravity of the detection box 26 is increased. The reset spring 24 and the telescopic rod 25 will shrink, and the overall position of the detection box 26 will drop. The button switch 23 will be pressed by the detection box 26, and the alarm bell 7 electrically connected to the button switch 23 will be energized and sound an alarm, thereby reminding the on-site staff to pay attention to the surrounding environment and take corresponding measures in time to avoid the expansion of losses.

[0041] The present invention can be explained by the following operation mode:

[0042] The control cabinet body 1 can be opened and closed by manually rotating the cabinet door 2, and the air supply blades 5 can quickly replace the air in the control cabinet body 1. Various electronic components can be installed on the connecting plate 6, and the alarm bell 7 can sound an alarm after power is turned on;

[0043] The servo motor 3 can drive the driving shaft 9 coaxially fixedly connected to its output end to rotate, so that the active bevel gear 10 coaxially fixedly connected to the driving shaft 9 and located in the linkage housing 8 can rotate. When the active bevel gear 10 rotates, the driven bevel gear 11 meshing therewith can rotate. When the driving shaft 9 rotates, it will drive the air supply blade 5 to rotate. By setting the servo motor 3, the linkage mechanism 30 can be driven by the bevel gear while driving the air supply blade 5, which greatly improves the linkage of the device, making the overall structure of the device more compact, and improving functionality and practicality.

[0044] Through the linkage of the linkage mechanism 30, the follower disc 16 will rotate with the rotation of the driven bevel gear 11. When the follower disc 16 rotates, the driving shaft 17 connected to the follower disc 16 away from the axis position can drive the piston plate 18 to reciprocate, and the pressure in the heat dissipation chamber 14 can be continuously changed. When the piston plate 18 slides to one side of the follower disc 16, through the connection of the connecting pipe 13 and the conical air guide 12, the hot air in the control cabinet body 1 will be sucked into the heat dissipation chamber 14, and the condensation heat dissipation device 15 can be used to initially cool it. When the piston plate 18 moves away from the follower disc 16, the air in the heat dissipation chamber 14 will be pressed out. Due to the special design of the connecting pipe 13 and the principle of gas throttling expansion, when the radius of the gas flow channel is reduced, the gas flow rate will be increased, and the gas temperature will drop accordingly, which will cause the air to be cooled twice. The air cooled twice will be introduced into the control cabinet body 1, thus completing the control of the air temperature in the control cabinet body 1, thereby ensuring the normal working environment of the electronic components in the control cabinet body 1;

[0045] The moisture-proof alarm mechanism 31 can detect and alarm the humidity in the control cabinet body 1. First of all, it should be noted that silica sol particles are placed in the detection box 26, and a plurality of small holes are provided at the bottom of the detection box 26. When the humidity in the control cabinet body 1 is too high, moisture enters the detection box 26 through the small holes, and the silica sol particles absorb moisture and expand. At this time, the weight of the silica sol particles is increased, and the overall gravity of the detection box 26 is increased. The reset spring 24 and the telescopic rod 25 will shrink, and the overall position of the detection box 26 will drop. The button switch 23 will be pressed by the detection box 26, and the alarm bell 7 electrically connected to the button switch 23 will be energized and sound an alarm, thereby reminding the on-site staff to pay attention to the surrounding environment and take corresponding measures in time to avoid the expansion of losses.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
