Description

Technical Field

[0001] This utility model relates to the field of electrical control equipment technology, and in particular to a comprehensive compensation cabinet. Background Technology

[0002] Existing compensation cabinets have ventilation holes on both sides to allow heat from the internal components to escape. However, this also makes it easier for dust to enter the cabinet and cover the components. Prolonged dust accumulation, especially when combined with moisture from the air, can corrode exposed components. This can lead to reduced insulation, short circuits, grounding issues, and even electric shock. Excessive dust buildup in humid conditions can also cause high electrostatic currents, posing a safety hazard to operators. Furthermore, excessive dust corrodes components, shortening their lifespan. Current methods mostly rely on manual cleaning during regular maintenance, which is cumbersome.

[0003] Therefore, in view of the fact that when a network compensation cabinet is left for a long time, dust in the air will accumulate and cover the components inside the compensation cabinet, which may cause short circuits, grounding and other faults, and even the risk of electric shock, a comprehensive compensation cabinet is proposed. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned problems by providing a comprehensive compensation cabinet. This utility model utilizes multiple sensors evenly distributed inside the cabinet, with a preset temperature value. When the temperature near the components rises above the preset value, the multiple sensors simultaneously send electrical signals to the air pump. The air pump, in conjunction with the suction pipe and multiple air pipes, sucks up and cleans the dust inside the cabinet. The sucked-up dust is then discharged into a collection box, thus completing the cleaning of the dust inside the cabinet. This avoids prolonged dust accumulation and prevents the absorption of moisture from the air by dust-covered components, which could corrode exposed components, lead to reduced insulation, short circuits, grounding faults, or even the risk of electric shock. To achieve the above-mentioned utility model objectives, the technical solution adopted is as follows:

[0005] According to one aspect of the present invention, a comprehensive compensation cabinet is provided, including a cabinet body, a power control unit being provided inside the cabinet body, multiple ventilation holes being provided on both sides of the cabinet body, and a cleaning component being provided inside the cabinet body for cleaning dust accumulated inside the cabinet body.

[0006] Preferably, the cleaning component includes a triggering device and a cleaning device.

[0007] Preferably, the cleaning device includes an air pump installed at the bottom of the cabinet, multiple air extraction pipes are provided on the inner wall of the cabinet, the multiple air extraction pipes are connected to the air pump, each air extraction pipe is provided with multiple branch pipes, each branch pipe is provided with multiple air extraction holes, a collection box is provided at the lower end of the cabinet, the collection box is connected to the air pump, and the cross-section of each air extraction pipe is a straight groove.

[0008] Preferably, each of the air extraction pipes is provided with a downwardly inclined connecting groove at the connection point between it and the multiple branch pipes.

[0009] Preferably, the collection box is a split drawer type, that is, the collection box is divided into an outer frame and a drawer, the drawer extends to the outside of the cabinet, a pair of photoelectric switches are provided in the drawer, and the photoelectric switches at the receiving end are electrically connected to the power control unit, and the outer frame is provided with a guide groove.

[0010] Preferably, a collection drawer is provided at the lower end of the cabinet body.

[0011] Preferably, both the drawer and the collection drawer are provided with a layer of dust-absorbing paper.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0013] The integrated compensation cabinet described in this utility model uses multiple sensors evenly arranged inside the cabinet. A preset temperature value is set. When the temperature near the components rises above the preset value, the multiple sensors simultaneously send an electrical signal to the air pump. The air pump, in conjunction with the air extraction pipe and multiple air pipes, sucks up and cleans the dust inside the cabinet. The sucked-up dust is then discharged into a collection box, thus completing the cleaning of the dust inside the cabinet.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of the utility model, and these aspects can be achieved even without these specific details.

[0022] Please see Figures 1 to 6 This utility model provides a comprehensive compensation cabinet, the technical solution of which is as follows:

[0023] The device includes a cabinet 1, which contains a power control unit 2. Both sides of the cabinet 1 have multiple ventilation holes 3. The cabinet 1 also contains a cleaning component for cleaning dust accumulated inside the cabinet 1.

[0024] The compensation cabinet is usually located indoors. During long-term placement, dust in the air can enter the cabinet 1 through multiple through-holes 3 on both sides of the cabinet 1, or when the door of the cabinet 1 is opened by the staff, dust can enter the interior. As a result, dust will accumulate on the power control unit 2 inside the cabinet 1. If the dust absorbs moisture from the air after being covered for a long time, it will corrode some exposed components. Being in this state for a long time may lead to reduced insulation, short circuits, grounding faults, and even the risk of electric shock. Excessive dust on the surface can also cause excessive electrostatic current in humid air, which may pose a danger to the staff during operation. Moreover, excessive dust on the surface will corrode the components, thereby shortening their service life. Furthermore, the accumulation of dust will prevent the heat emitted by the power control unit 2 from being dissipated, which may easily lead to damage or failure of the components inside the power control unit 2.

[0025] Although the existing power distribution cabinet 1 has multiple ventilation holes 3 on both sides, the power distribution cabinet located indoors is mostly stationary. Without external force, the dust inside the cabinet 1 cannot be discharged, which can easily lead to the above situation.

[0026] A cleaning component is installed inside the cabinet 1. When the dust inside the cabinet 1 reaches a certain level, the cleaning component will automatically start to clean the dust inside the cabinet 1, thereby reducing the occurrence of component corrosion and reduced component lifespan caused by dust accumulation, and improving the lifespan and stability of the components of the power control unit 2.

[0027] The cleaning assembly includes a triggering device and a cleaning device. The triggering device includes multiple temperature sensors 4 evenly placed on the inner wall of the cabinet 1. The multiple temperature sensors 4 are divided into multiple groups and are evenly installed on the inner wall of the cabinet 1. All of the multiple temperature sensors 4 are electrically connected to the cleaning device.

[0028] When dust accumulates and covers the components, the heat emitted by the components cannot be dissipated, causing the components to heat up. Consequently, the temperature near the components will rise. A temperature preset value is set. When the temperature near the components rises to exceed the preset value, the corresponding temperature sensor 4 detects that the temperature exceeds the preset value and sends an electrical signal to the cleaning device. The cleaning device then starts to clean the accumulated dust inside the cabinet 1.

[0029] However, the components of the power control unit 2 inside the cabinet 1 generate heat during operation. When the load is too large, the components will overload and the heat will continue to rise until normal operation is restored. The cleaning device will only be activated when the temperature detected by multiple temperature sensors 4 continuously exceeds the preset value for a certain period of time. This avoids the instantaneous or short-term temperature rise caused by component overload, which would lead to frequent cleaning and other unpredictable events.

[0030] The cleaning device includes an air pump 5 installed at the bottom of the cabinet 1. Multiple air extraction pipes 6 are provided on the inner wall of the cabinet 1. The multiple air extraction pipes 6 are connected to the air pump 5. Each air extraction pipe 6 is provided with multiple branch pipes 7. Each branch pipe 7 has multiple air extraction holes. A collection box 8 is provided at the lower end of the cabinet 1. The collection box 8 is connected to the air pump 5. The cross-section of each air extraction pipe 6 is a straight groove.

[0031] When the temperature sensor 4 detects that the temperature of the corresponding component continues to rise and exceeds the preset value for a certain period of time, the temperature sensor 4 sends an electrical signal to the air pump 5, and the air pump 5 starts to pump air. The dust accumulated on the components inside the cabinet 1 enters the air extraction pipe 6 under the action of the air pump 5, then passes through the branch pipe 7, and then enters the air extraction pipe 6 again. Finally, it enters the collection box 8 through the air pump 5. This process lasts for a period of time and can be adjusted according to your own needs.

[0032] Because the components themselves generate heat, and the temperature will continue to rise under load or overload conditions, it is necessary to set more than half of the temperature sensors 4 to give electrical signals to the air pump 5 within the same time period so that the air pump 5 can start. This avoids the continuous and frequent starting of the air pump 5, which could cause the circuits of the components inside the cabinet 1 to swing or even fall off, and thus reduce the service life of the air pump 5.

[0033] The components of the power control unit 2 inside the cabinet 1 occupy about 80% of the cabinet 1's capacity when placed. Generally, the diameter of the suction pipe 6 that can be placed inside the cabinet 1 is relatively small, provided it does not obstruct the operator's operation. However, the cross-section of each suction pipe 6 is a straight groove, i.e., flat. This reduces the longitudinal distance while increasing the lateral distance, which increases the diameter. This allows the suction pump 5 to suction more quickly, thereby reducing the suction time and avoiding vibrations during the suction process or swaying of the component circuitry due to suction force. This improves the stability of the component operation during suction.

[0034] Each of the aforementioned exhaust pipes 6 and multiple branch pipes 7 is provided with a downwardly inclined connecting groove 12. If the connection between the exhaust pipe 6 and multiple branch pipes 7 is directly welded, and the inner wall of the connection is right-angled, during the suction process of the exhaust pump 5, some dust tends to accumulate at the corner when passing through the corner of the connection. If external wind enters the cabinet 1 through the through hole 3, or if the staff opens the cabinet door of the cabinet 1, the wind force generated may blow this part of the dust out and fall back onto the components, which may affect the heat dissipation of the components. By providing a downwardly inclined connecting groove 12 at each connection between the exhaust pipe 6 and multiple branch pipes 7, the space at the corner is increased, reducing the occurrence of some dust accumulating at the corner during the suction process of the exhaust pump 5, improving the dust suction efficiency of the exhaust pump 5, reducing the probability of dust accumulating on the components again, and improving the stability of the suction.

[0035] The collection box 8 is a split drawer type, meaning it consists of an outer frame and a drawer 801. The drawer 801 extends to the outside of the cabinet 1. A pair of photoelectric switches 9 are installed inside the drawer 801, and the photoelectric switches 9 at the receiving end are electrically connected to the power control unit 2. The outer frame has a guide groove 11. After the air pump 5 sucks up the dust inside the cabinet 1, the dust falls into the collection box 8. During regular equipment maintenance, the dust in the collection box 8 can be cleaned to prevent excessive accumulation, which could potentially cause health problems for staff. The collection box 8 is located at the lower end of the air pump 5. However, if the staff wants to clean the dust, they need to move the entire collection box 8 out, which is quite cumbersome. The collection box 8 is designed as a split drawer 801 type, that is, the collection box 8 is divided into an outer frame and a drawer 801. The drawer 801 extends to the outside of the cabinet 1. That is, the drawer 801 can be pulled out from the outside of the cabinet 1. When the staff cleans it, they only need to pull out the drawer 801, clean the dust inside the drawer 801, and then put the drawer 801 back in place to complete one cleaning of the collection box 8, which improves the convenience of the staff to clean the dust inside the collection box 8.

[0036] During the process of vacuum pump 5 sucking dust into collection box 8, if too much dust accumulates inside collection box 8 and needs to be cleaned, the dust accumulated inside collection box 8 will float disorderly inside collection box 8. In order to prevent staff from forgetting to clean collection box 8 when maintaining equipment, a pair of photoelectric switches 9 are installed in drawer 801. When the disorderly floating dust continuously blocks the light emitted by photoelectric switch 9, it proves that too much dust has accumulated inside collection box 8. At this time, photoelectric switch 9 sends an electrical signal to power control unit 2 to inform staff that too much dust has accumulated inside collection box 8 and it should be cleaned to avoid affecting the health of staff.

[0037] The dust accumulated in the collection box 8 will not float under the impact of the air pump 5, which can easily cause dust backflow. The outer frame is provided with a guide groove 11 to block most of the dust that does not need to float, reducing the possibility of dust from the collection box 8 flowing back into the air pump 5. This improves the stability of the air pump 5 and reduces the possibility of dust backflow into the air pump 5, which could affect the operation of the air pump 5 and reduce its service life.

[0038] The lower part of the cabinet 1 is equipped with a collection drawer 10. When the air pump 5 sucks and cleans the dust in the cabinet 1 through the air extraction pipe 6 and branch pipe 7, some dust on the components at the top of the cabinet 1 may not be able to enter the corresponding branch pipe 7 and will fall downwards under the action of gravity. In the process, it may enter other branch pipes 7, but some dust will still fall to the lower part of the cabinet 1. If this part of the dust is not cleaned, it may be covered and accumulated on the components again under the action of external wind or the wind generated by the staff opening the cabinet door. The collection drawer 10 at the lower part of the cabinet 1 is used to collect the dust that is not sucked into the air extraction pipe 6 when the air pump 5 is sucking, reduce the occurrence of the above situation, and improve the stability of the normal operation of the components.

[0039] Both drawer 801 and collection drawer 10 are equipped with a layer of dust-absorbing paper. When dust enters drawer 801 and collection drawer 10, if there is insufficient adsorption force, the dust will drift randomly. Due to the restriction of the guide groove 11 and the outer frame, the dust in drawer 801 is unlikely to drift back into cabinet 1. However, the dust in collection drawer 10 is very likely to drift onto the components again under the action of external wind or the wind generated when the cabinet door is opened. Therefore, a layer of dust-absorbing paper is provided on both drawer 801 and collection drawer 10 to absorb the dust entering drawer 801 and collection drawer 10, so as to avoid the above situation. The dust-absorbing paper is a disposable item. When the staff cleans drawer 801 and collection drawer 10, the old dust-absorbing paper is torn off and a new dust-absorbing paper is to be pasted on for the next dust cleaning inside the cabinet.

[0040] Example 1:

[0041] Condition: Multiple temperature sensors 4 simultaneously send electrical signals to the air pump 5;

[0042] Working process: When the dust on the components in the power distribution cabinet accumulates to a certain extent, the heat emitted by the components cannot be discharged. Consequently, the corresponding temperature sensor 4 detects that the temperature near the sensor exceeds the preset value for a period of time. At the same time, an electrical signal is given to the air pump 5. The dust accumulated on the components in the cabinet 1 enters the air extraction pipe 6 under the action of the air pump 5, then passes through the branch pipe 7, and then enters the air extraction pipe 6 again. Finally, it enters the collection box 8 through the air pump 5. This process will last for a period of time, which can be manually modified, such as 3 minutes, 5 minutes, etc. The dust sucked into the collection box 8 by the air pump 5 will adhere to the dust absorption paper under the action of the dust absorption paper. The accumulated dust will drift disorderly under the impact of the air pump 5. Due to the obstruction of the outer frame and the guide groove 11, it cannot flow back into the air pump 5.

[0043] When the air pump 5 sucks up and cleans the dust in the cabinet 1 through the air pump pipe 6 and the branch pipe 7, some dust on the components on the top of the cabinet 1 may not be able to enter the corresponding branch pipe 7 and will fall down under the action of gravity. In the process, it may enter other branch pipes 7, but some dust will still fall to the bottom of the cabinet 1. A collection drawer 10 is provided at the bottom of the cabinet 1, and the falling dust will fall onto the collection drawer 10.

[0044] When the dust in the collection box 8 accumulates to a certain extent, the air pump 5 will pump air again, causing the dust in the collection box 8 to drift disorderly. As a result, the infrared light of the two photoelectric switches 9 in the drawer 801 will be continuously blocked by the dust. At this time, the photoelectric switches 9 will give an electrical signal to the power control unit 2 to inform the staff that there is too much dust inside the collection box 8 and it should be cleaned to avoid the staff forgetting to clean the dust in the collection box 8 and the collection drawer 10 during maintenance.

[0045] Example 2:

[0046] Condition: Multiple temperature sensors 4 intermittently provide electrical signals to the air pump 5;

[0047] Working process: When the dust on the components in the power distribution cabinet accumulates to a certain extent, the heat emitted by the components cannot be dissipated. Consequently, the corresponding temperature sensor 4 detects that the temperature near the sensor has been exceeding the preset value for a period of time, and at this time, it is necessary to clean the dust.

[0048] If multiple temperature sensors 4 intermittently send electrical signals to the air pump 5 at this time, the temperature rise is not caused by dust. It may be because the components are operating under load or overload, causing the component temperature to rise continuously. However, not all components are operating under load, so the air pump 5 will not start at this time.

[0049] Another scenario involves a component malfunction, such as a short circuit. The component will continuously heat up, and the corresponding temperature sensor 4 will send an electrical signal to the vacuum pump 5 once the temperature exceeds the preset value. However, if only one sensor is active, the vacuum pump 5 will not start. If the temperature continues to rise and temperature sensor 4 continues to send electrical signals to the vacuum pump 5, it indicates a high probability of a component malfunction. The vacuum pump 5 will then send an electrical signal to the power control unit 2, informing the staff of the potential component failure and prompting them to check it promptly to prevent further damage.

[0050] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
