Description

Technical Field

[0001] This invention relates to the field of switchgear technology, and in particular to an intelligent defrosting switchgear. Background Technology

[0002] Switchgear is a type of electrical equipment. External lines first enter the main control switch inside the switchgear, and then enter the branch control switches. Each branch circuit is set according to its needs. Condensation inside the switchgear is an important environmental factor affecting its normal operation. During operation, condensation causes moisture to condense on the equipment surface, which accelerates mold growth, reduces electrical insulation strength, accelerates metal corrosion, leads to oxidation of contact surfaces, and increases contact resistance, posing a threat to the safety of the switchgear. This article provides technical insights into switchgear.

[0003] Currently, the existing technology CN202110582934.0 discloses an intelligent cooling and dehumidifying switch cabinet. In this invention, the end of the air-exhaust plate away from the inner side wall of the switch cabinet is hinged to the slider through a connecting plate. The two side walls of the switch cabinet are respectively provided with air inlet pipe and air outlet pipe. An air heating box is provided on the side wall of the switch cabinet. This solves the problem that the current switch cabinet cannot effectively control the temperature and humidity inside the switch cabinet. Excessive temperature or humidity will damage the electrical components inside the switch cabinet. This avoids affecting the normal operation of the switch cabinet, enables the switch cabinet to effectively protect the circuit it is connected to, and improves the working efficiency of the switch cabinet.

[0004] The above study of switchgear revealed the following problems:

[0005] The switch cabinet can only be heated and dehumidified by an air heating box. Because the electronic components inside the switch cabinet generate a lot of heat during operation, and the air heating box also generates heat, the internal temperature of the switch cabinet is likely to be too high, which can affect the normal use of the switch cabinet. As a result, the switch cabinet cannot use the heat generated by its own electronic components to perform heat circulation and defrosting.

[0006] This invention primarily addresses the problem that switchgear cannot utilize the heat generated by its own electronic components for thermal circulation and defrosting. Summary of the Invention

[0007] To address the aforementioned technical problems, this invention provides an intelligent defrosting switch cabinet to solve the problems described in the background section.

[0008] The purpose and effect of the present invention, an intelligent defrosting switch cabinet, are achieved by the following specific technical means: an intelligent defrosting switch cabinet, including a frame, an intelligent component inside the frame, the intelligent component including a cooling fan and a temperature sensor, the temperature sensor being located on the inner wall of the frame near the cooling fan, a through frame running through the middle of the frame, and a heat dissipation mesh embedded at the upper end of the frame.

[0009] Furthermore, the frame contains a processor and a speed control switch. The speed control switch is connected to the cooling fan via a wire loop, and the temperature sensor is connected to both the processor and the speed control switch via wire loops. A rotating component is located on the side of the frame near the cooling fan.

[0010] Furthermore, the frame has two internal cavities. The cooling fan is located in one of the internal cavities, and the through frame passes through the connection between the two internal cavities. There are two cooling fans, located at the upper and lower ends of the frame, and the two cooling fans are used vertically opposite each other.

[0011] Furthermore, the interior of the through frame is hollow, and the heat dissipation mesh is located at the upper end of the inner cavity on the side of the frame away from the cooling fan.

[0012] Furthermore, the rotating assembly includes a main shaft, a first blade, a second blade, a branch shaft, a rotating sphere, a fan blade, an air bladder, protrusions, and ball bearings. The main shaft rotates on the inner wall of one side of the frame, the first blade and the second blade rotate at the upper and lower ends of the main shaft, respectively, while the branch shaft rotates at the end of the main shaft away from the inner wall of the frame. The rotating sphere rotates on the outside of the branch shaft, the fan blades swing on one side of the rotating sphere, the air bladder is embedded inside the branch shaft, the protrusions are distributed on both sides of the air bladder, and the ball bearings roll on the side of the branch shaft near the air bladder.

[0013] Furthermore, the main shaft is arranged horizontally, located at the center of the cooling fans at both ends inside the frame, and the main shaft and the through frame are horizontally corresponding, with the main shaft rotating 360° on the inner wall of the frame.

[0014] Furthermore, the length of the first blade is 1-2 cm shorter than the length of the second blade, both the first and second blades are curved, and both the first and second blades weigh 10-30g.

[0015] Furthermore, the branch shaft has a groove on the side near the rotating ball inside, and the fan blades, airbags, protrusions and balls are all located inside the groove. The number of grooves is matched with the number of rotating balls, and the branch shaft rotates synchronously when the main shaft rotates.

[0016] Furthermore, the fan blade and the rotating sphere are matched together, and the fan blade swings at an angle outside the branch shaft through the rotating sphere, with one side of the rotating sphere being less than 1 cm away from the protrusion.

[0017] Furthermore, the airbag surrounds the side of the rotating sphere, and the airbag is bent and deformed inside the groove of the branch shaft. The side of the airbag away from the protrusion slides and compresses with the ball.

[0018] Furthermore, the ball rolls inside the groove of the branch shaft, and as the ball rolls, it is squeezed against one side of the airbag.

[0019] Furthermore, the lower end of the heat dissipation mesh is provided with a support, and a through pipe runs through the inside of the support. An adsorption ring and a baffle are embedded in the inner wall of the through pipe, and a water collection rack is provided on the side of the adsorption ring away from the baffle.

[0020] Furthermore, the bracket surrounds the lower end of the heat dissipation mesh, and the bracket is arranged in an inverted isosceles trapezoid. Multiple through-tubes are provided inside the bracket, and the internal diameter of the through-tubes is 2-4cm.

[0021] Furthermore, the baffle surrounds the lower end of the adsorption ring, and 4-6 baffles are provided inside the through tube. The baffle is arranged in an inverted "V" shape, with a thickness of 0.2-0.4cm. The baffle is made of a deformable material, such as rubber.

[0022] Furthermore, the adsorption ring is made of sponge material, and the adsorption ring is matched with the water collection frame. The water collection frame is located at the lower end of the adsorption ring and is arranged in a semi-circular ring shape. The water collection frame is located inside the support. Beneficial effects

[0023] 1. The temperature sensor senses the temperature on one side of the frame. When the temperature inside the frame is high, the temperature sensor transmits the signal to the processor. The processor then transmits the control signal to the speed control switch. The speed control switch can adjust the speed of the motor inside the cooling fan, enabling this type of switch cabinet to intelligently adjust the speed of the cooling fan.

[0024] 2. When the cooling fan is running, the cooling fan blows airflow to the outside of the first blade or the second blade. By utilizing the weight difference between the first blade and the second blade, the spindle can rotate relative to the inner wall of the frame.

[0025] 3. When the main shaft rotates, the branch shaft rotates synchronously. When the branch shaft rotates, the outer fan blades swing at an angle through the rotating ball. Since the main shaft and the through frame are horizontally aligned, the fan blades assist the hot air to enter the interior of the through frame during rotation. At this time, the hot air flows through the inner cavity on one side of the frame to the inner cavity on the other side. The flow of hot air inside the frame can accelerate the evaporation of condensation inside the frame and also accelerate the condensation dehumidification efficiency, thus achieving a quick solution to condensation.

[0026] 4. When the branch shaft rotates, the ball bearings roll inside the branch shaft due to its rotation. As the ball bearings roll, they are squeezed against one side of the airbag, causing the airbag to deform as a whole. Since the distance between one side of the rotating ball bearing and the protrusion is less than 1 cm, after the airbag is deformed, the protrusion on one side of the airbag can quickly squeeze against one side of the rotating ball bearing. The deformation of the airbag can assist the rotating ball bearing to swing at an angle inside the branch shaft, which in turn can assist the fan blades to swing at an angle, and further assist the fan blades to swing on the outside of the branch shaft.

[0027] 5. After the condensate drips into the inside of the heat dissipation mesh and into the inside of the through pipe, the baffle can prevent the condensate from entering the inside of the frame through the through pipe. The condensate is adsorbed by the adsorption rings on both sides of the upper part of the baffle. After being absorbed, the condensate drips into the inside of the water collection rack for collection, preventing the condensate from accumulating on the side of the baffle.

[0028] 6. After the hot air enters the inner cavity of the frame near the heat dissipation mesh through the through-frame, the hot air flows upward. When the hot air reaches the lower end of the through-tube, since the thickness of the baffle is 0.2-0.4cm, the hot air and the airflow driven by the cooling fan impact the lower end of the baffle, causing the baffle to bend at an angle. The hot air then enters the interior of the heat dissipation mesh through the through-tube and is discharged. This allows the switch cabinet to help the hot air circulate inside the frame, thereby achieving the effect of defrosting. Attached Figure Description

Detailed Implementation

[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Example

[0040] As attached Figure 1 To be continued Figure 8 As shown:

[0041] Example 1: An intelligent defrosting switch cabinet includes a frame 1. The frame 1 is equipped with an intelligent component, which includes a cooling fan 101 and a temperature sensor 102. The temperature sensor 102 is located on the inner wall of the frame 1 near the cooling fan 101. A through frame 103 passes through the middle of the frame 1. A heat dissipation mesh 104 is embedded at the upper end of the frame 1.

[0042] Among them: Frame 1, the inside of Frame 1 is equipped with a processor and a speed control switch. The speed control switch is connected to the cooling fan 101 through a wire circuit, and the temperature sensor 102 is connected to the processor and the speed control switch through a wire circuit respectively. A rotating component is provided on the side of Frame 1 near the cooling fan 101.

[0043] Temperature sensor 102 senses the temperature on one side inside the frame 1. When the temperature inside the frame 1 is high, temperature sensor 102 transmits a signal to the processor. The processor transmits a control signal to the speed control switch. The speed control switch can adjust the speed of the motor inside the cooling fan 101, so that this type of switch cabinet can intelligently adjust the speed of the cooling fan 101.

[0044] The cooling fan 101 has two inner cavities inside the frame 1. The cooling fan 101 is located in one inner cavity inside the frame 1, and the through frame 103 passes through the connection between the two inner cavities. There are two cooling fans 101, located at the upper and lower ends inside the frame 1, and the two cooling fans 101 are used in a vertically corresponding manner.

[0045] The cooling fan 101 has an internal motor, which is the power source for the rotation of the cooling fan 101.

[0046] The through frame 103 and the heat dissipation mesh 104 are arranged in a hollow shape. The heat dissipation mesh 104 is located at the upper end of the inner cavity of the frame 1 on the side away from the cooling fan 101.

[0047] Example 2: Refer to the attached instruction manual Figure 2-5 It can be seen that the difference between Embodiment 2 and Embodiment 1 is that the rotating assembly includes a main shaft 2, a first blade 201, a second blade 202, a branch shaft 203, a rotating sphere 3, a fan blade 301, an airbag 302, a protrusion 303, and a ball bearing 304. The main shaft 2 rotates on the inner wall of one side of the frame 1. The first blade 201 and the second blade 202 rotate at the upper and lower ends of the main shaft 2, respectively. The branch shaft 203 rotates at the end of the main shaft 2 away from the inner wall of the frame 1. The rotating sphere 3 rotates on the outside of the branch shaft 203. The fan blade 301 swings on one side of the rotating sphere 3. The airbag 302 is embedded in the inside of the branch shaft 203. The protrusion 303 is distributed on both sides of the airbag 302. The ball bearing 304 rolls on the side of the branch shaft 203 near the airbag 302.

[0048] Among them: main shaft 2, the main shaft 2 is arranged horizontally, the main shaft 2 is located at the center of the cooling fans 101 at both ends inside the frame 1, and the main shaft 2 is horizontally corresponding to the through frame 103. The main shaft 2 rotates 360° on the inner wall of the frame 1.

[0049] A first blade 201 and a second blade 202, wherein the length of the first blade 201 is 1-2 cm shorter than the length of the second blade 202, both the first blade 201 and the second blade 202 are curved, and both the first blade 201 and the second blade 202 weigh 10-30g.

[0050] The weight of the first blade 201 and the second blade 202 is 10-30g each, so as to avoid the first blade 201 and the second blade 202 being too heavy and thus only able to swing on the outside of the main shaft 2.

[0051] The length of the first blade 201 is 1-2 cm shorter than the length of the second blade 202, so that when the cooling fan 101 is running, the cooling fan 101 blows the airflow to the outside of the first blade 201 or the second blade 202. By utilizing the weight difference between the first blade 201 and the second blade 202, the main shaft 2 can rotate relative to the inner wall of the frame 1.

[0052] Branch shaft 203 has a groove on the side of the inside of the branch shaft 203 near the rotating ball 3. The fan blade 301, air bag 302, protrusion 303 and ball 304 are all located inside the groove. The number of grooves is matched with the number of rotating balls 3. When the main shaft 2 rotates, the branch shaft 203 rotates synchronously.

[0053] Rotating sphere 3 and fan blade 301 are provided together. The fan blade 301 swings at an angle to the outside of the branch shaft 203 via the rotating sphere 3. One side of the rotating sphere 3 is less than 1 cm away from the protrusion 303.

[0054] The distance between one side of the rotating sphere 3 and the protrusion 303 is less than 1cm, so that when the airbag 302 deforms, the protrusion 303 can be quickly squeezed to one side of the rotating sphere 3.

[0055] Airbag 302 and protrusion 303, airbag 302 surrounds the side of rotating ball 3, airbag 302 is bent and deformed inside the groove of branch shaft 203, and the side of airbag 302 away from protrusion 303 slides and is squeezed with ball 304.

[0056] The ball bearing 304 rolls inside the groove of the branch shaft 203, and when it rolls, it is squeezed to one side of the airbag 302.

[0057] Wherein: When the cooling fan 101 is running, the cooling fan 101 blows airflow to the outside of the first blade 201 or the second blade 202, and uses the weight difference between the first blade 201 and the second blade 202 to facilitate the spindle 2 to rotate relative to the inner wall of the frame 1.

[0058] When the main shaft 2 rotates, the branch shaft 203 rotates synchronously. When the branch shaft 203 rotates, the outer fan blade 301 swings at an angle through the rotating ball 3. Since the main shaft 2 and the through frame 103 are horizontally aligned, the fan blade 301 assists the hot air to enter the interior of the through frame 103 during rotation. At this time, the hot air flows through the inner cavity on one side of the frame 1 to the inner cavity on the other side. By utilizing the flow of hot air, the condensation evaporation in the frame 1 can be accelerated, and the condensation dehumidification efficiency can also be accelerated, thereby achieving a quick solution to condensation.

[0059] When the branch shaft 203 rotates, the ball bearing 304 rolls inside the branch shaft 203 due to the rotation of the branch shaft 203. When rolling, the ball bearing 304 is squeezed to one side of the airbag 302, and the airbag 302 is deformed as a whole. Since the distance between one side of the rotating ball 3 and the protrusion 303 is less than 1 cm, after the airbag 302 is deformed, the protrusion 303 on one side of the airbag 302 can quickly squeeze to one side of the rotating ball 3. The deformation of the airbag 302 can assist the rotating ball 3 to swing at an angle inside the branch shaft 203, which in turn can assist the fan blade 301 to swing at an angle, thereby further assisting the fan blade 301 to swing on the outside of the branch shaft 203.

[0060] Example 3: Refer to the appendix of the instruction manual Figure 2 , 6 -8 It can be seen that the difference between Embodiment 3 and Embodiments 1 and 2 is that the lower end of the heat dissipation mesh 104 is provided with a support 4, the inside of the support 4 is through a through pipe 401, the inner wall of the through pipe 401 is inlaid with an adsorption ring 403 and a baffle 402, and a water collection rack 404 is provided on the side of the adsorption ring 403 away from the baffle 402.

[0061] Among them: bracket 4, bracket 4 surrounds the lower end of heat dissipation mesh 104, bracket 4 is arranged in an inverted isosceles trapezoid, and multiple through pipes 401 are provided inside the bracket 4, the internal diameter of through pipes 401 is 2-4cm;

[0062] The internal diameter of the through-pipe 401 is 2-4cm, which facilitates the passage of hot air through the through-pipe 401 into the interior of the heat dissipation mesh 104 for exhaust.

[0063] Baffle 402 surrounds the lower end of adsorption ring 403. There are 4-6 baffles 402 inside the through tube 401. The baffle 402 is arranged in an inverted "V" shape. The thickness of baffle 402 is 0.2-0.4cm. Baffle 402 is made of deformable material, such as rubber.

[0064] The thickness of baffle 402 is 0.2-0.4cm, which facilitates the bending and deformation of baffle 402;

[0065] Hot air flows to the lower end of the through pipe 401. Since the thickness of the baffle 402 is 0.2-0.4cm, the hot air and the wind force driven by the cooling fan 101 impact the lower end of the baffle 402, causing the baffle 402 to bend at an angle. The specific principle can be referred to the backflow preventer of the range hood.

[0066] The baffle 402 is set in an inverted "V" shape. After the condensate drips inside the heat dissipation mesh 104 into the inside of the through pipe 401, the baffle 402 can prevent the condensate from entering the inside of the frame 1 through the through pipe 401.

[0067] The adsorption ring 403 and the water collection rack 404 are made of sponge material. The adsorption ring 403 and the water collection rack 404 are matched and set together. The water collection rack 404 is located at the lower end of the adsorption ring 403. The water collection rack 404 is set in a semi-circular ring shape and is located inside the support 4.

[0068] Wherein: After the condensate drips inside the heat dissipation mesh 104 into the inside of the through pipe 401, the baffle 402 can prevent the condensate from entering the inside of the frame 1 through the through pipe 401. The condensate is adsorbed by the adsorption rings 403 on both sides of the upper end of the baffle 402. After being absorbed, the condensate drips into the inside of the water collection rack 404 for collection, thus preventing the condensate from accumulating on the side of the baffle 402.

[0069] After hot air enters the inner cavity of the frame 1 near the heat dissipation mesh 104 through the through-frame 103, the hot air flows upward. When the hot air reaches the lower end of the through-pipe 401, since the thickness of the baffle 402 is 0.2-0.4cm, the hot air and the airflow driven by the cooling fan 101 impact the lower end of the baffle 402, causing the baffle 402 to bend at an angle. The hot air then enters the heat dissipation mesh 104 through the through-pipe 401 and is discharged. This allows the switch cabinet to help the hot air circulate inside the frame 1, thereby achieving the effect of defrosting.
