Description

Technical Field

[0001] This invention relates to the field of power cabinet technology, and in particular to a ring main unit that achieves multi-angle dehumidification. Background Technology

[0002] As a crucial component of smart distribution networks, the construction of distribution automation projects has progressed rapidly in recent years, transitioning distribution automation systems from pilot projects to full-scale implementation. Currently, ring main units (RMMs), as vital equipment in distribution networks, play a crucial role in connecting the distribution ring network and distributing electrical energy. Because RMMs are often installed on the ground and connected to cable trenches, the air humidity inside is high. During rainy weather (especially in spring), condensation or even water accumulation can occur inside the RMM, easily causing short circuits and damage to components.

[0003] With the application of power distribution automation systems, secondary equipment such as DTUs have been added to ring main units, placing higher demands on the operating environment inside these units. High humidity, in particular, can severely impact the reliability of the secondary equipment and even cause damage. Therefore, dehumidification of the ring main units is necessary to improve the operational safety of the equipment within.

[0004] In existing technologies, dehumidification of ring main units is achieved through dehumidifying fans. However, the fixed angle at which the dehumidifying fan draws in air creates multiple dead zones within the unit. Over time, these dead zones develop severe corrosion, leading to the failure of the entire ring main unit's seal.

[0005] Therefore, it is necessary to design a new ring network cabinet to achieve rapid air output from multiple angles, thus avoiding the corrosion problem in the dead corners of the cabinet caused by the fixed angle of traditional dehumidifiers. Summary of the Invention

[0006] The technical problem to be solved by the embodiments of the present invention is to provide a ring network cabinet that can achieve multi-angle dehumidification, which can realize rapid air output from multiple angles and avoid the problem of corrosion in the dead corners of the cabinet caused by the fixed angle of traditional dehumidifiers.

[0007] To address the aforementioned technical problems, embodiments of the present invention provide a ring network cabinet for multi-angle dehumidification, comprising a cabinet body; the cabinet body is equipped with a controller and its connected dehumidifier, an air duct structure, and multiple humidity sensors; wherein,

[0008] The dehumidifier and the multiple humidity sensors are all fixed in a designated dead corner position inside the cabinet, and the air duct structure is installed on the air outlet of the dehumidifier.

[0009] The controller is used to receive the humidity sensed by all humidity sensors, and when it is determined that the humidity sensed by at least one humidity sensor is greater than a preset threshold, it controls the dehumidifier to turn on and drives the air duct structure to extend along a predetermined trajectory so that the air outlet of the dehumidifier follows the extension movement of the air duct structure to sweep over the dead corner position of each humidity sensor.

[0010] The airway structure includes a first sleeve, a second sleeve, a third sleeve, and a fourth sleeve that are rotatably connected in sequence; wherein,

[0011] The end of the first sleeve away from the second sleeve is fixed to the air outlet of the dehumidifier, and the end facing the second sleeve is embedded in the second sleeve and forms a rotatable connection. A first motor connected to the controller is provided on the outer surface of the middle part between the two ends.

[0012] The second sleeve is fitted with one end of the first sleeve. A first external gear ring is provided on the outer periphery of the second sleeve to cooperate with the first motor. After bending a certain length toward one end of the third sleeve, it is embedded in the third sleeve to form a rotatable connection. A second motor connected to the controller is provided on the outer surface of the middle part between the two ends.

[0013] The end face of the third sleeve that is fitted with one end of the second sleeve is inclined and a second external gear ring that cooperates with the second motor is provided on the outer periphery. After bending a certain length toward one end of the fourth sleeve, it is embedded in the fourth sleeve to form a rotatable connection. A third motor connected to the controller is provided on the outer surface of the middle part between its two ends.

[0014] The end face of the fourth sleeve that is fitted onto the third sleeve is inclined, and a third external gear ring that cooperates with the third motor is provided on the outer periphery. The end face of the fourth sleeve that is away from the third sleeve is flared.

[0015] The predetermined trajectory includes a first motion trajectory, a second motion trajectory, and a third motion trajectory; the first motion trajectory is achieved by the first motor driving the second sleeve to extend a certain length in a direction away from the dehumidifier; the second motion trajectory is achieved by the second motor driving the third sleeve to extend a certain length in the direction of the curved end of the second sleeve; the third motion trajectory is achieved by the third motor driving the fourth sleeve to extend a certain length in the direction of the curved end of the third sleeve.

[0016] The bending direction of the bent end of the second sleeve is the same as that of the bent end of the third sleeve.

[0017] If the dehumidifier is located below the cabinet, the bending direction of the bent end of the second sleeve and the bent end of the third sleeve are both upward, and the bending angle of both is 30 degrees upward.

[0018] If the dehumidifier is located above the cabinet, the bending direction of the bent end of the second sleeve and the bent end of the third sleeve are both downward, and the bending angle of both is 60 degrees downward.

[0019] The rotatable connection is achieved through a threaded connection.

[0020] The cabinet also includes at least one airflow guide plate to guide airflow.

[0021] Implementing the embodiments of the present invention has the following beneficial effects:

[0022] This invention uses a controller to drive the air duct structure at the dehumidifier outlet to extend along a predetermined trajectory, so that the dehumidifier's airflow follows the extension of the air duct structure to sweep over the dead corners where each humidity sensor is located. This enables rapid airflow from multiple angles and avoids the corrosion problem in the dead corners of the cabinet caused by the fixed angle of traditional dehumidifiers.

[0029] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] like Figure 1 As shown in the figure, a ring network cabinet for multi-angle dehumidification is proposed in an embodiment of the present invention, including a cabinet body 1; the cabinet body 1 is equipped with a controller 11 and a dehumidifier 12 connected to it, an air duct structure 13, and multiple humidity sensors 14; wherein,

[0031] The dehumidifier 12 and multiple humidity sensors 14 are fixed in a designated dead corner position inside the cabinet 1, and an air duct structure 13 is installed on the air outlet of the dehumidifier 12. It should be noted that the dead corner position inside the cabinet 1 is predetermined based on the actual structure, and the number of humidity sensors 14 is determined based on the actual number of dead corners in the cabinet 1. The dehumidifier 12 can be installed in a dead corner position or in other positions, and can be flexibly adjusted.

[0032] The controller 11 is used to receive the humidity sensed by all humidity sensors 14, and when it is determined that the humidity sensed by at least one humidity sensor 14 is greater than a preset threshold, it controls the dehumidifier 12 to turn on and drives the air duct structure 13 to extend along a predetermined trajectory, so that the air outlet of the dehumidifier 12 follows the extension movement of the air duct structure 13 to sweep over the dead corner position where each humidity sensor 14 is located, thereby enabling multi-angle rapid air intake and avoiding the problem of cabinet dead corner corrosion caused by the fixed angle of traditional dehumidifiers.

[0033] In embodiments of the present invention, the air passage structure 13 can be of various types, including but not limited to a rotating vector nozzle structure. For example, Figure 2 As shown, the airway structure 13 includes a first sleeve 131, a second sleeve 132, a third sleeve 133, and a fourth sleeve 134 that are sequentially rotatably connected (e.g., by a threaded connection); wherein,

[0034] The end of the first sleeve 131 away from the second sleeve 132 is fixed to the air outlet of the dehumidifier 12, and the end facing the second sleeve 132 is embedded in the second sleeve 132 and forms a rotatable connection. The outer surface of the middle part between the two ends is provided with a first motor M1 connected to the controller 1.

[0035] The second sleeve 132 is fitted onto one end of the first sleeve 131. A first external gear ring C1 is provided on the outer periphery of the second sleeve 132, which cooperates with the first motor M1. After bending a certain length toward the third sleeve 133, it is embedded in the third sleeve 133 to form a rotatable connection. A second motor M2 connected to the controller 1 is provided on the outer surface of the middle part between the two ends.

[0036] The end face of the third sleeve 133, which is fitted onto one end of the second sleeve 132, is inclined, and a second external gear ring C2 that cooperates with the second motor M2 is provided on its outer periphery. The end of the third sleeve 133 that faces the fourth sleeve 134 is bent to a certain length and then embedded in the fourth sleeve 134 to form a rotatable connection. A third motor M3 connected to the controller 1 is provided on the outer surface of the middle part between the two ends. The bending direction of the bent end of the second sleeve 132 is consistent with that of the bent end of the third sleeve 133.

[0037] The end face of the fourth sleeve 134 that is fitted with the third sleeve 133 is inclined and the outer periphery is provided with a third external gear ring C3 that cooperates with the third motor M3. The end face of the fourth sleeve 134 that is away from the third sleeve 133 is flared.

[0038] The predetermined trajectory includes a first motion trajectory executed sequentially (such as...). Figure 3 As shown), the second motion trajectory (as shown) Figure 4 (as shown) and the third motion trajectory (as shown) Figure 5 (As shown); the first motion trajectory is achieved by the controller 1 driving the first motor M1 to extend the second sleeve 132 a certain length away from the dehumidifier 12; the second motion trajectory is achieved by the controller 1 driving the second motor M2 to extend the third sleeve 133 a certain length along the curved end of the second sleeve 132; the third motion trajectory is achieved by the controller 1 driving the third motor M3 to extend the fourth sleeve 134 a certain length along the curved end of the third sleeve 133.

[0039] It is understandable that the forward and reverse rotation of the first motor M1, the second motor M2, and the third motor M3 can be controlled to extend the air passage structure 13 to achieve multi-angle air output or retract the air passage structure 13 to achieve multi-angle air intake. The specific method can be flexibly adjusted according to the actual situation.

[0040] At this time, if the dehumidifier 11 is located below the cabinet 1, the bending direction of the bent ends of the second sleeve 132 and the third sleeve 133 is upward, and the bending angle of both is 30 degrees upward or other angles. If the dehumidifier 11 is located above the cabinet 1, the bending direction of the bent ends of the second sleeve 132 and the third sleeve 133 is downward, and the bending angle of both is 60 degrees downward or other angles. It should be noted that the length and angle of the bent ends of the second sleeve 132 and the third sleeve 133 can be flexibly adjusted according to actual conditions, provided that all the dead corner positions of the humidity sensors 14 are covered.

[0041] In this embodiment of the invention, if there is a component barrier S between the air duct structure 13 and one or more humidity sensors 14, the airflow can be guided by adding an airflow guide plate 15 or other structures inside the cabinet 1. The specific position can be flexibly adjusted according to actual needs.

[0042] At this time, with Figure 1 For example, the dehumidification operation mode of a ring main unit that achieves multi-angle dehumidification in an embodiment of the present invention is as follows:

[0043] Step 1, component setup: Install a humidity sensor 14, a dehumidifier 12, a controller 11, and an air duct structure 13 in a dead corner inside the cabinet 1.

[0044] Step 2, Debugging: Receive data from humidity sensor 14 through controller 11 to control dehumidifier 12 and air duct structure 13, and confirm the control effect.

[0045] Step 3, Testing: By adjusting the airway structure 13, ensure that the airflow of the airway structure 13 can sweep through the dead corners where each humidity sensor 14 is located. If there is a component obstruction S between the airway structure 13 and the humidity sensor 14, adjust the position of the component. If the position of the component cannot be adjusted, add structures such as airflow guide plate 15 to guide the airflow.

[0046] Step 4, Dehumidification of Dead Corners: Based on the humidity sensor 14 located in the dead corner, the controller 11 determines whether the humidity meets the dehumidification requirements of the dehumidifier 12. If it does, the controller 11 turns on the dehumidifier 12 to draw in air for dehumidification and adjusts the air duct structure 13 to achieve rapid air output from multiple angles. This allows the air duct structure 13 to be aimed at the dead corners that do not meet the requirements, accelerating the flow of air and achieving cooling.

[0047] Implementing the embodiments of the present invention has the following beneficial effects:

[0048] This invention uses a controller to drive the air duct structure at the dehumidifier outlet to extend along a predetermined trajectory, so that the dehumidifier's airflow follows the extension of the air duct structure to sweep over the dead corners where each humidity sensor is located. This enables rapid airflow from multiple angles and avoids the corrosion problem in the dead corners of the cabinet caused by the fixed angle of traditional dehumidifiers.

[0049] The above description discloses only preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
