Description

Technical Field

[0001] This utility model belongs to the field of power distribution cabinet technology, and specifically relates to an outdoor waterproof power distribution cabinet. Background Technology

[0002] A distribution cabinet is an electrical device used for the distribution, control, and protection of electricity. Distribution cabinets are usually classified into indoor distribution cabinets and outdoor distribution cabinets according to their installation location. Indoor distribution cabinets are often used for power control within buildings, while outdoor distribution cabinets are often used for power distribution and control of outdoor power facilities. Distribution cabinets are widely used in industrial, commercial, and civil fields, playing a vital role in the distribution, control, and protection of electricity.

[0003] Chinese patent CN219980104U discloses an outdoor waterproof distribution cabinet that can prevent rainwater from entering the cabinet by actively closing the ventilation openings when it rains. However, the device uses a water collection tank and a pressure spring to drive the closure of the ventilation openings.

[0004] However, the power in this design comes from the downward pressure of the water collection trough. When the rainfall is not heavy enough, the weight of the water collection trough is insufficient, resulting in insufficient downward pressure. Before reaching the maximum pressure value, the ventilation opening cannot be completely closed, which may cause rainwater to enter the distribution box. In addition, the drainage pipe of the rain collection trough is relatively narrow. Foreign objects may block the drainage outlet, causing the spring to keep pressing down, thus keeping the ventilation opening closed. Consequently, the temperature inside the distribution box rises and damages the electrical components.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes an outdoor waterproof power distribution cabinet to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model is an outdoor waterproof power distribution cabinet, including a rain sensor component installed on the top of the cabinet body, a cleaning component installed on one side of the rain sensor component, ventilation vent switch components installed on both sides of the interior of the cabinet body, ventilation vents running through both sides of the cabinet body, heat dissipation plates installed inside the ventilation vents, and water-cooled heat dissipation pipes running through the top and bottom of the interior of the cabinet body.

[0009] Furthermore, the rain sensing component includes a pressure release switch. A pressure release switch is provided in the middle of the upper surface of the distribution cabinet. Four springs are fixedly installed at the four corners of the upper surface of the distribution cabinet. A rain collection trough is fixedly installed above the springs. A cleaning component is provided on one side of the rain collection trough. A drain outlet is provided on the same side of the rain collection trough as the cleaning component. A rubber port is provided at the bottom of the drain outlet for connecting to the water-cooled heat dissipation pipe.

[0010] Furthermore, the cleaning assembly includes a protective shell, which is fixedly installed on one side of the rainwater collection trough and located directly above the drain outlet. A cleaning motor is installed inside the protective shell, and the output end of the cleaning motor passes through the protective shell. A cleaning fan blade is fixedly connected to the output end of the cleaning motor, and the cleaning fan blade is located inside the drain outlet.

[0011] Furthermore, the ventilation opening switch assembly includes a time relay, which is disposed on the top of one end of the inner wall of the power distribution cabinet. The ventilation opening switch assembly includes a switch motor, which is fixed to one side inside the power distribution cabinet. The switch motor is connected to a ventilation baffle through gears. The ventilation baffle is slidably connected to both sides inside the power distribution cabinet and is located directly above the ventilation opening.

[0012] Furthermore, a heat dissipation plate is fixedly installed inside the vent, and the heat dissipation plate has several folded blades inside.

[0013] Furthermore, the cabinet door is hinged to the front of the distribution cabinet body, and a handle is fixedly installed on the front of the cabinet door.

[0014] Furthermore, a fixed bracket is provided at the bottom of the power distribution cabinet.

[0015] This utility model has the following beneficial effects:

[0016] The pressure relief switch transmits an electrical signal to the relay, which then drives the switch motor to move downwards, eventually completely blocking the ventilation opening. The electronic control method for lowering the ventilation baffle is more precise and provides better blocking of the ventilation opening.

[0017] The cleaning motor drives the cleaning blades to continuously clean the drain outlet, preventing blockages that could keep the rainwater collection trough constantly under full load, which would prevent the power distribution cabinet from dissipating heat in time and thus damage electronic components.

[0018] 3. By inserting the water-cooled heat dissipation pipe 7 into the drain outlet and intercepting rainwater, the rainwater flows from the top of the water-cooled heat dissipation pipe to the bottom and is discharged. This allows the power distribution cabinet to dissipate heat even when the ventilation opening is blocked. The two heat dissipation systems broaden the applicable scenarios of this power distribution cabinet.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0031] Please see Figures 1-6 As shown, this utility model is an outdoor waterproof power distribution cabinet, including a rain sensor component 2 installed on the top of the power distribution cabinet body 1, a cleaning component 3 installed on one side of the rain sensor component 2, ventilation vent switch components 4 installed on both sides of the interior of the power distribution cabinet body 1, ventilation vents 5 running through both sides of the power distribution cabinet body 1, heat dissipation plates 6 installed inside the ventilation vents 5, and water-cooled heat dissipation pipes 7 running through the top and bottom of the interior of the power distribution cabinet body 1.

[0032] The rain sensor component 2 detects the amount of rainfall. If the rainfall exceeds or falls below a certain threshold, the rain sensor component 2 triggers the vent switch component 3 to cover or open the vent 5. When open, the vent is cooled by the heat sink 6, and when covered, the vent is cooled by the water-cooled heat pipe 7. The cleaning component 3 prevents the rain sensor component 2 from being affected by foreign objects.

[0033] In actual use, if it is raining heavily, the rain sensor component 2 will store rainwater while discharging it. The speed at which the rainwater is discharged has a maximum value. If the rainfall is too heavy, the speed at which the rain sensor component 2 stores rainwater will be greater than the speed at which it discharges rainwater. As a result, the rain sensor component 2 will store a certain amount of rainwater and reach a critical value, triggering the ventilation opening switch component 4. The ventilation opening component 4 will then move downward to cover the ventilation opening 5, preventing rainwater from entering the power distribution cabinet 1. At this time, the water-cooled heat dissipation pipe 7 will use rainwater to assist in heat dissipation.

[0034] When the rain stops or the rainfall decreases, causing the rain level sensor 2 to drop below a critical value, it will trigger the vent switch 4 to move upward, thereby opening the cover on the vent 5. If the rainfall is heavy enough, it will not reach the critical value of the rain level sensor 2, and the vent switch 4 will not be triggered. The vent switch 4 will remain in its original state, and the heat sink 6 can then provide adequate protection against the rain.

[0035] This invention automatically senses rainfall through the rain sensor component 2 and drives the ventilation opening switch component 4 to move downward, thereby covering the ventilation opening 5. When the rain stops or the rain lessens, the rain sensor component 2 can trigger the ventilation opening switch component 4 to move upward, thereby opening the cover of the ventilation opening 5. This protects the power distribution cabinet 1 from water ingress due to heavy rain and improves the adaptability of this invention in rainy environments.

[0036] In one embodiment, the rain sensing component 2 includes a pressure release switch 201. The pressure release switch 201 is located in the middle of the upper surface of the distribution cabinet 1. Four springs 202 are fixedly installed at the four corners of the upper surface of the distribution cabinet 1. A rain collection trough 203 is fixedly installed above the springs 202. A cleaning component 3 is provided on one side of the rain collection trough 203. A drain outlet 204 is provided on the same side of the rain collection trough 203 as the cleaning component 3. A rubber outlet 205 is provided at the bottom of the drain outlet 204 for connecting to the water-cooled heat dissipation pipe 7.

[0037] The rainwater collection trough 203 collects rainwater, and the drain outlet 204 discharges the collected rainwater. The rainwater collection trough 203 collects rainwater, which increases its own weight and causes it to move downwards, compressing and deforming the spring 202 installed at the bottom. At the same time, as the rainwater flows in the rainwater collection trough 203, it can trigger the pressure release switch 201 installed at the bottom. The pressure release switch 201 transmits the current signal to the vent switch assembly 4 through the wire.

[0038] As rainwater inside the water collection trough 203 is gradually discharged through the drainage trough, the force applied to the spring 202 at its bottom gradually decreases, so that the spring 202 can push the water collection trough 203 to move upward. The rain collection trough 203 rises and moves away from the pressure release switch 201. The pressure release switch 201 transmits the current signal to the vent switch assembly through the wire.

[0039] In actual use, the rain collection trough 203 increases its own weight by collecting rainwater, and the drain outlet 204 is used to drain water to reduce its own weight. When the speed of collecting rainwater is greater than the speed of draining, the rain collection trough 203 moves downward until it presses the pressure release switch 201. At this time, the top of the water-cooled heat dissipation pipe 7 passes through the rubber opening 205, and the pressure release switch 201 is also triggered, thereby transmitting a signal to the vent switch assembly 4.

[0040] In one embodiment, the cleaning component 3 includes a protective shell 301, which is fixedly installed on one side of the rainwater collection trough 203 and located directly above the drain outlet 204. A cleaning motor 302 is disposed inside the protective shell 301, and the output end of the cleaning motor 302 passes through the protective shell 301. A cleaning blade 303 is fixedly connected to the output end of the cleaning motor 302, and the cleaning blade 303 is located inside the drain outlet 204.

[0041] The protective shell 301 protects the cleaning motor 302. The cleaning motor 302, along with the drive shaft at its output end, drives the cleaning blade 303 to rotate in the drain outlet 204, thereby cleaning the drain outlet 204 and preventing foreign objects from clogging the drain outlet 204 and preventing rainwater from being discharged from the rain collection trough 203. By starting the cleaning motor 302, the cleaning blade 303, which is fixedly connected to the output end, is driven to rotate. Since the outer surface of the cleaning blade 303 is rotated with the inside of the drain outlet 204, the cleaning blade 303 can clean foreign objects inside the drain outlet 204 when it rotates, thus ensuring that the rainwater inside the rain collection trough 203 is discharged smoothly.

[0042] In one embodiment, the ventilation vent switch assembly 4 includes a time relay 401, which is disposed at the top of one end of the inner wall of the distribution cabinet 1. The ventilation vent switch assembly 4 also includes a switch motor 402, which is fixed to one side inside the distribution cabinet 1. The switch motor 402 is connected to a ventilation baffle 403 via gears. The ventilation baffle 403 is slidably connected to both sides inside the distribution cabinet 1 and is positioned directly above the ventilation vent 5.

[0043] The relay 401 receives the electrical signal from the pressure relief switch 201, and then controls the current input of the switch motor 402 to control the operation of the switch motor 402. When the pressure relief switch 201 is triggered as the rain collection trough 203 moves, it sends an electrical signal to the relay 401, which then controls the switch motor 402 to start and stop. When the switch motor 402 is started, it rotates, thereby driving the ventilation baffle 403 to move downward through the gears and racks, thus blocking the ventilation opening 5.

[0044] In actual use, the coil of relay 401 is connected to the pressure relief switch 201, and the normally open contact of relay 401 is connected to the power circuit of switch motor 402. When the switch is closed, the relay coil is energized and starts timing. Switch motor 402 is energized and runs. After the timing of relay 401 ends, the normally open contact opens and switch motor 402 stops running. Switch motor 402 drives the gear to move the ventilation baffle 403 downward, thereby completing the blocking of the entire ventilation opening 5. Through the cooperation of relay 401 and switch motor 402, the ventilation opening 5 can be blocked more accurately, which is more conducive to protecting the power distribution cabinet from the influence of rainwater.

[0045] In one embodiment, for the above-mentioned ventilation opening 5, a heat dissipation plate 6 is fixedly installed inside the ventilation opening 5, and the heat dissipation plate 6 is provided with a plurality of folded blades 8 inside.

[0046] In actual use, air convection is formed through the gaps inside the heat sink 6, which promotes the heat dissipation of the distribution cabinet. The folded blades 8 inside the heat sink 6 can prevent rainwater from entering the distribution cabinet in the event of light rain, which helps to protect the distribution cabinet.

[0047] In one embodiment, for the aforementioned power distribution cabinet, the cabinet door 9 is hinged to the front of the power distribution cabinet 1 via a hinge, and a handle 10 is fixedly installed on the front of the cabinet door 9. In actual use, since the cabinet door 9 and the power distribution cabinet 1 have a good sealing degree, adding a handle 10 to the cabinet door 9 makes it convenient for users to open the cabinet door 9.

[0048] In one embodiment, for the aforementioned power distribution cabinet, a fixed bracket 11 is provided at the bottom of the power distribution cabinet 1 to help fix the power distribution cabinet on the ground.

[0049] In summary, by means of the above-mentioned technical solution of this utility model, the rainwater collection trough 203 collects rainwater to increase its own weight, and the rainwater in the rainwater collection trough 203 is discharged through the drain outlet 204 to reduce the weight of the rainwater collection trough 203. When the rain is heavy enough that the drainage speed is less than the collection speed, the weight of the water in the rainwater collection trough 203 continuously increases, thereby depressuring the spring 202 below the rainwater collection trough 203 until the pressure of the rainwater collection trough 203 is triggered. The pressure release switch 201 located at the bottom of the rainwater collection trough 203 is triggered, and the pressure release switch 201 is transmitted to the relay 40. 1. Relay 401 delays the electrical signal, causing switch motor 402 to run for a period of time. Switch motor 402 drives ventilation baffle 403 to move downwards. After switch motor 402 completely blocks ventilation opening 5, it stops running. When rainwater collection trough 203 releases switch 201, water-cooled heat dissipation pipe 7 is inserted into rubber opening 205 in drain outlet 204. Rainwater flows in from the top of water-cooled heat dissipation pipe 7 and flows out from the bottom of water-cooled heat dissipation pipe 7, carrying away some of the heat of the distribution cabinet, thereby maintaining a constant temperature inside the distribution cabinet 1 and protecting the circuit.

[0050] Through the above technical solutions: 1. The pressure relief switch 201 transmits an electrical signal to the relay 401, which in turn drives the switch motor 402 to operate. The switch motor 402 moves the ventilation baffle 403 downward, finally completely blocking the ventilation opening 5. The descent of the ventilation baffle 403 is controlled electronically, which is more precise and provides better blocking effect for the ventilation opening. 2. The cleaning motor 302 drives the cleaning blades 303 to operate, thereby continuously cleaning the drain outlet 204. This prevents the rainwater collection trough 203 from being constantly overloaded due to blockage of the drain outlet 204, which would prevent the power distribution cabinet from dissipating heat in time and thus damage electronic components. 3. A water-cooled heat dissipation pipe 7 is inserted into the drain outlet 204 and intercepts rainwater, allowing the rainwater to flow from the top of the water-cooled heat dissipation pipe 7 to the bottom and be discharged. This allows the power distribution cabinet to dissipate heat even when the ventilation opening 5 is blocked. The two heat dissipation systems broaden the applicable scenarios of this power distribution cabinet.
