Description

Technical Field

[0001] This invention relates to the field of power distribution cabinet technology, and more specifically, to a water-resistant outdoor power distribution cabinet and its application method. Background Technology

[0002] Distribution cabinets are used in situations where loads are concentrated and there are many circuits. They distribute the electrical energy of a certain circuit of the previous level power distribution equipment to the nearest load. Depending on their location in the circuit system, distribution cabinets are usually divided into multiple levels.

[0003] Currently, outdoor distribution cabinets are often located in complex environments, and some areas may be at risk of water immersion. Existing methods usually involve raising the cabinet or internal components to prevent water immersion. While this can achieve a certain degree of water immersion prevention, the cost is very high, making it difficult to promote and popularize. There is a need for a water-resistant method that is easy to promote and popularize. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a water-proof outdoor power distribution cabinet and its application method, in view of the above-mentioned defects of the prior art.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] A water-resistant outdoor power distribution cabinet is constructed, comprising a power distribution cabinet and a base, wherein a positioning tube is provided on the base; the bottom surface of the power distribution cabinet has an opening that mates with the positioning tube, and the outer surface of the positioning tube is sealed to the inner wall of the opening; an auger is movably inserted inside the positioning tube; a cavity is provided inside the base, and a drainage hole is provided on the base communicating with the cavity; the lower end of the positioning tube passes into the cavity; a cover plate is provided inside the cavity to seal the lower end of the positioning tube; a floating waterproof sealing cavity is provided on the lower surface of the cover plate, and a drive motor, a motor controller, a power supply, and a wireless module are provided inside the waterproof sealing cavity; a sealed bearing is provided on the cover plate to mate with the movable end of the drive motor, and the movable end of the drive motor is coaxially and fixedly connected to the auger; a mounting bracket for mounting the cover plate is provided inside the cavity, and the mounting bracket is connected to the inner top of the cavity through a longitudinal guide component; the lower side surface of the positioning tube is connected to the outside through a drainage pipe.

[0007] The water-proof outdoor power distribution cabinet of the present invention includes a groove on the base that mates with the power distribution cabinet; and a plurality of positioning tubes passing through the bottom of the groove.

[0008] In the water-proof outdoor power distribution cabinet of the present invention, the upper end of the positioning tube is flush with the bottom surface of the power distribution cabinet.

[0009] The water-proof outdoor power distribution cabinet of the present invention includes a guide assembly comprising two longitudinally arranged guide sleeves fixed to the inner top of the cavity, a guide rod movably disposed within the guide sleeve, and a screw disposed at the lower end of the guide rod; and a threaded sleeve rotatably disposed on the mounting bracket and correspondingly connected to the screw.

[0010] The water-proof outdoor power distribution cabinet of the present invention has a movable sealing door on the outer surface of the base that is directly opposite the mounting bracket.

[0011] The water-proof outdoor power distribution cabinet of the present invention has the outlet of the drainage pipe located in the middle or upper part of the outer surface of the power distribution cabinet.

[0012] A method for applying a water-resistant outdoor power distribution cabinet, using the aforementioned water-resistant outdoor power distribution cabinet, is implemented as follows:

[0013] It includes three self-switching modes: heat dissipation mode, low power mode, and high power mode;

[0014] Cooling mode: In non-immersion conditions, the drive motor is controlled by external wireless commands to rotate the auger, which extracts the air from the distribution cabinet and discharges it through the drain hole and drain pipe to cool the distribution cabinet.

[0015] Low power mode: When water gets inside the distribution cabinet, the auger will create a negative pressure inside the positioning tube, drawing the water from the bottom of the distribution cabinet into the cavity through the positioning tube and draining it out through the drain hole.

[0016] High power consumption mode: When water accumulates in the cavity, the waterproof sealing cavity floats up under the guidance of the guide component due to the buoyancy of the water. When the cover plate is attached to and the lower end of the sealing positioning tube is closed, the space inside the distribution cabinet is isolated from the cavity. If the distribution cabinet is submerged in water at this time, the negative pressure generated by the auger will cause the water in the distribution cabinet to be discharged through the positioning tube and drainage pipe.

[0017] The beneficial effects of this invention are as follows: it includes three self-switching modes: heat dissipation mode, low power consumption mode, and high power consumption mode. In heat dissipation mode, under non-water immersion conditions, the drive motor is controlled by external wireless commands to rotate the auger, drawing air out of the distribution cabinet and discharging it through the drain hole and drain pipe, thus dissipating heat from the distribution cabinet. In low power consumption mode, when the distribution cabinet is immersed in water, the auger's suction creates a negative pressure inside the positioning tube, drawing water from the bottom of the distribution cabinet into the cavity through the positioning tube and discharging it through the drain hole. At this time, no water accumulates in the positioning tube, the auger experiences almost zero resistance, and power consumption is low. Very small; High power consumption mode: When water accumulates in the cavity, the waterproof sealing cavity floats up under the guidance of the guide component due to the buoyancy of the water. When the cover plate is attached to and the lower end of the sealing tube is closed, the space inside the distribution cabinet is isolated from the cavity. If the distribution cabinet is submerged in water at this time, the negative pressure generated by the auger will cause the water in the distribution cabinet to be discharged through the positioning tube and the drainage pipe. At this time, water accumulates in the positioning tube, and the rotation resistance of the auger will be large, which is the high power consumption mode. By applying the method of this application, the above three states can be switched automatically, which can be applied to three scenarios. The energy saving effect is good, and the modification of the cabinet is minimal, which is conducive to promotion and popularization. Attached Figure Description

[0018] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. The drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort:

[0019] Figure 1 This is a schematic diagram of the structure of a water-resistant outdoor power distribution cabinet according to a preferred embodiment of the present invention. Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0021] The preferred embodiment of the present invention is a water-resistant outdoor power distribution cabinet, such as... Figure 1As shown, the device includes a distribution cabinet 1 and a base 2. A positioning tube 20 is installed on the base 2. The bottom surface of the distribution cabinet 1 has an opening 10 that mates with the positioning tube 20. The outer surface of the positioning tube 20 is sealed to the inner wall of the opening 10. An auger 21 is movably inserted into the positioning tube 20. A cavity 22 is provided inside the base 2. A drain hole 23 is provided on the base 2 that connects to the cavity 22. The lower end of the positioning tube 20 is inserted into the cavity 22. A cover plate 24 is provided inside the cavity 22 to cover the lower end of the positioning tube 20. A floating waterproof sealing cavity 25 is provided on the lower surface of the cover plate 24. A drive motor 25 is installed inside the waterproof sealing cavity 25. 0. Motor controller (not shown in the figure, can be freely set according to actual needs), power supply (not shown in the figure, can be freely set according to actual needs), and wireless module (not shown in the figure, can be freely set according to actual needs). The cover plate 24 is provided with a sealed bearing that cooperates with the movable end of the drive motor 250. The movable end of the drive motor 250 is coaxially and fixedly connected to the auger 21. The cavity 22 is provided with a mounting bracket 26 for mounting the cover plate 24. The mounting bracket 26 is connected to the inner top of the cavity 22 through a longitudinal guide component 27. The lower side surface of the positioning tube 20 is connected to the outside through a drainage pipe 28.

[0022] It includes three self-switching modes: heat dissipation mode, low power mode, and high power mode;

[0023] Cooling mode: In non-immersion conditions, the drive motor is controlled by external wireless commands to rotate the auger, which extracts the air from the distribution cabinet and discharges it through the drain hole and drain pipe to cool the distribution cabinet.

[0024] Low power mode: When water is submerged in the distribution cabinet, the auger's suction will create a negative pressure inside the positioning tube, drawing water from the bottom of the distribution cabinet into the cavity through the positioning tube and draining it out through the drain hole. At this time, no water accumulates in the positioning tube, the auger experiences almost zero resistance, and the power consumption is very low.

[0025] High power consumption mode: When water accumulates in the cavity, the waterproof sealing cavity floats up under the guidance of the guide component due to the buoyancy of the water. When the cover plate is attached to and the lower end of the positioning tube is closed, the space inside the distribution cabinet is isolated from the cavity. If the distribution cabinet is submerged in water at this time, the negative pressure generated by the auger will cause the water in the distribution cabinet to be discharged through the positioning tube and the drainage pipe. At this time, water accumulates in the positioning tube, and the auger rotation resistance will be greater, which is the high power consumption mode.

[0026] The method described in this application can automatically switch between the three states, which can be applied to three different scenarios. It has good energy-saving effect and requires minimal modification to the cabinet, making it suitable for widespread adoption.

[0027] Preferably, the base 2 is provided with a groove 29 that cooperates with the power distribution cabinet; multiple positioning tubes 20 are inserted through the bottom of the groove 29, and the upper end of the positioning tubes 20 is flush with the bottom surface of the power distribution cabinet 1; the structure is simple, the groove can effectively reduce the installation difficulty of the power distribution cabinet; the positioning tubes can achieve drainage function while also playing a good positioning role.

[0028] Preferably, the guide assembly 27 includes two longitudinally arranged guide sleeves 270 fixed to the inner top of the cavity 22. A guide rod 271 is movably disposed within the guide sleeve 270, and a screw 272 is disposed at the lower end of the guide rod 271. A threaded sleeve 260 corresponding to the screw is rotatably disposed on the mounting bracket 26. A movable sealing door is disposed on the outer surface of the base 2, which is directly opposite the mounting bracket. During installation or maintenance, the movable sealing door on the base 2 can be opened, and the mounting bracket can be easily installed or maintained through the detachable connection between the screw and the threaded sleeve. The movable sealing door can adopt an existing structure, which will not be described in detail here.

[0029] Preferably, the outlet of the drainage pipe 28 is located in the middle or upper part of the outer surface of the distribution cabinet 1. Of course, it is understandable that it can also be set at other heights depending on the actual site conditions.

[0030] A method for applying a water-resistant outdoor power distribution cabinet, using the aforementioned water-resistant outdoor power distribution cabinet, is implemented as follows:

[0031] It includes three self-switching modes: heat dissipation mode, low power mode, and high power mode;

[0032] Cooling mode: In non-immersion conditions, the drive motor is controlled by external wireless commands to rotate the auger, which extracts the air from the distribution cabinet and discharges it through the drain hole and drain pipe to cool the distribution cabinet.

[0033] Low power mode: When water gets inside the distribution cabinet, the auger will create a negative pressure inside the positioning tube, drawing the water from the bottom of the distribution cabinet into the cavity through the positioning tube and draining it out through the drain hole.

[0034] High power consumption mode: When water accumulates in the cavity, the waterproof sealing cavity floats up under the guidance of the guide component due to the buoyancy of the water. When the cover plate is attached to and the lower end of the sealing positioning tube is closed, the space inside the distribution cabinet is isolated from the cavity. If the distribution cabinet is submerged in water at this time, the negative pressure generated by the auger will cause the water in the distribution cabinet to be discharged through the positioning tube and drainage pipe.
