Description

Technical Field

[0001] The present invention belongs to the technical field of electrical cabinet dehumidification, and specifically relates to a dehumidification device applied to the inside of a switch cabinet. Background Art

[0002] As a control device of the power system, the switch cabinet is widely used in the power transmission link. The power system usually needs to operate for a long time. During its operation, humidity is one of the important factors affecting the operation stability of the switch cabinet. If the humidity inside the switch cabinet is too high, it will easily lead to a decrease in electrical insulation performance, and then cause safety hazards such as electrical failures, short circuits, and even fires. In order to effectively avoid the harm of moisture to electrical equipment, a dehumidifier inside the switch cabinet was born;

[0003] Common dehumidification technologies include condensation dehumidification. Its principle is to use the refrigeration system inside the device to cool the air below the dew point temperature, condense the water vapor in the air into water droplets, and then discharge them. Existing dehumidification devices usually use a direct current pipeline method to discharge the collected water droplets outside the switch cabinet. However, in practice, the hose used for drainage may cause the water flow in the pipe to accumulate and cannot be discharged due to extrusion and blockage, resulting in the problem that the collected water droplets will flow back. If the backflow water droplets are not processed, they may fall back into the switch cabinet and damage the electrical equipment. Summary of the Invention

[0010] Preferably, the adjusting component includes a rectangular frame which is fixedly installed on the top of the housing. Four blades are movably hinged in the rectangular frame. The right rotating shafts of the four blades are all movably hinged with connecting pieces. The right sides of the four connecting pieces are all movably hinged with round shafts. A strip is movably sleeved on the outer edge of the four round shafts. Four elliptical grooves are equidistantly formed in the strip. The bottom sides of the inner walls of the four elliptical grooves are all in contact with the outer edge of the round shaft. The rear end of the strip is fixedly connected with a telescopic rod, and the fixed end of the telescopic rod is fixedly installed with the housing.

[0011] Preferably, the condensing component includes a heat sink. A plurality of heat dissipation tubes are installed through the heat sink. Copper sheets are fixedly installed at the left ends of the plurality of heat dissipation tubes. The copper sheets are fixedly connected with the left inner wall of the housing.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] As Figures 1 to 10 shown, the embodiment of the present invention provides a dehumidification device applied to the inside of a switch cabinet, including an outer shell 1, a fixing component 2 is fixedly installed on the back of the outer shell 1, and also includes a linkage condensation control mechanism, which includes two adjusting components 3, the two adjusting components 3 are fixedly installed at the upper and lower ends of the outer shell 1, a condensing component 4 is fixedly installed inside the outer shell 1, and a control component 6 is fixedly installed on the right side of the condensing component 4;

[0030] A water outlet component 5, the water outlet component 5 is fixedly installed on the left side of the condensing component 4, the water outlet component 5 includes a collection box 51, guide pieces 52 are fixedly installed on both sides of the top of the collection box 51, a three-way pipe 53 is fixedly connected to the bottom of the collection box 51, a round groove 54 is annularly opened at the top of the three-way pipe 53, a water collecting shell 55 is fixedly connected to the top of the three-way pipe 53, a small floating ball liquid level switch is installed in the water collecting shell 55. When the storage capacity of water in the water collecting shell 55 reaches 75% of the internal space of the shell, the magnetic reed switch of the small floating ball will be turned on, and the buzzer in the controller 61 will emit an alarm signal. A floating ball 56 is movably installed inside the water collecting shell 55, a limit ring 57 is fixedly installed on the outer edge of the top of the floating ball 56, a roller 58 abuts against the top end of the floating ball 56, and a travel switch 59 is movably hinged to the rotating shaft of the roller 58; the installation position of the limit ring 57 is on the outer side of the top of the water collecting shell 55, and the travel switch 59 is fixedly connected to the inner wall of the outer shell 1;

[0031] When the hose connected to the outside of the tee 53 is blocked and the water flow cannot be discharged, the liquid will first continuously accumulate and rise in the tee 53 from the blocked place until it flows upward through the circular groove 54 into the water collecting shell 55 evenly and pushes the floating buoy 56 to float upward. When the water storage in the water collecting shell 55 reaches 75% of the internal space of the shell, the buzzer emits an alarm signal, and the floating buoy 56 just touches the roller 58, causing it to transmit the displacement signal to the travel switch 59. When the travel switch 59 receives the travel signal, it immediately stops the operation of the semiconductor refrigeration sheet 45 through the controller 61. At this time, some of the water droplets still attached to the back of the collection box 51 will continue to pour into the water collecting shell 55 with redundant space through the tee 53 until the blocked hose is unclogged, solving the problem that the hose used for drainage may cause the water flow in the pipe to accumulate and cannot be discharged due to extrusion and blockage, resulting in the backflow of the collected water droplets and affecting electrical safety;

[0032] Among them, a plurality of long holes 11 are opened on the front side of the outer shell 1, and three first fans 13 are fixedly installed on the back of the outer shell 1. A plurality of round holes 12 are opened on both sides of the three first fans 13;

[0033] When the round holes 12 capture the external air, the three first fans 13 can also be started, so as to quickly suck the external air into the outer shell 1. Through the copper sheet 43, part of the heat of the heat sink 41 can also be transferred to the metal outer shell 1, thereby expanding the heat dissipation area;

[0034] Among them, the fixing component 2 includes a fixing block 21. The fixing block 21 is fixedly installed on the left side of the back of the outer shell 1. A round rod 22 is installed through the inside of the fixing block 21, and two movable blocks 23 are movably sleeved on the outer edge of the round rod 22;

[0035] By rotating and adjusting the angles of the two movable blocks 23 on the round rod 22, the rotation angle of the entire device can be installed, or the connection lengths of the upper and lower movable blocks 23 with the inner wall of the switch cabinet are different, and the entire device can be installed at an inclined angle;

[0036] Among them, the adjusting component 3 includes a rectangular frame 31. The rectangular frame 31 is fixedly installed on the top of the outer shell 1. Four blades 32 are movably hinged in the rectangular frame 31. The right rotating shafts of the four blades 32 are all movably hinged with connecting pieces 33. The right sides of the four connecting pieces 33 are all movably hinged with round shafts 34. A long strip 35 is movably sleeved on the outer edges of the four round shafts 34. Four elliptical grooves 36 are equidistantly opened in the long strip 35. The bottom sides of the inner walls of the four elliptical grooves 36 are all in contact with the outer edges of the round shafts 34. When the long strip 35 moves, only the bottom sides of the inner walls of the four elliptical grooves 36 frictionally roll with the round shafts 34. The rear end of the long strip 35 is fixedly connected with a telescopic rod 37, and the fixed end of the telescopic rod 37 is fixedly installed with the outer shell 1;

[0037] During the process of the upper and lower groups of second fans 44 blowing out hot air, the regulating component 3 can also be activated to ensure that the hot air flow will not be recycled into the housing 1 by the first fan 13 again. When the telescopic rod 37 increases its stroke, it will push the circular shaft 34 to rotate and displace forward by a certain distance through a plurality of elliptical grooves 36 formed in the long strip 35. At this time, multiple blades 32 will rotate clockwise and open in the rectangular frame 31. At this time, the hot air will be blown obliquely towards the front side of the housing 1. By adjusting the position of the telescopic rod 37, the air outlet angle can be controlled;

[0038] Among them, the condensation component 4 includes heat sinks 41. A plurality of heat dissipation tubes 42 are installed through the heat sinks 41. Copper sheets 43 are fixedly installed at the left ends of the plurality of heat dissipation tubes 42. The copper sheets 43 are fixedly connected to the left inner wall of the housing 1. Two groups of second fans 44 are fixedly installed at the upper and lower ends of the heat sinks 41. Four semiconductor refrigeration chips 45 are fixedly installed on the back of the heat sinks 41. A collection box 51 is fixedly installed at the bottom of the four semiconductor refrigeration chips 45;

[0039] When the four semiconductor refrigeration chips 45 operate, they will capture the water vapor-containing air entering the housing 1 from the round hole 12, condense it into beads, and convert it into water droplets. When the water vapor condenses into water droplets, they will continuously fall downward into the collection box 51 under the influence of gravity;

[0040] Among them, the control component 6 includes a controller 61. The controller 61 is fixedly installed on the inner wall of the housing 1. A buzzer is provided in the controller 61. An interface 62 is fixedly installed at the top of the controller 61. A display screen 63 is fixedly installed on the front side of the controller 61; The bottom of the three-way pipe 53 is installed through the bottom of the housing 1, the display is installed through the front side of the housing 1, and the interface 62 is installed through the top of the housing 1;

[0041] The device can be powered through the interface 62. The condensation component 4 of the device can be controlled through the controller 61, and the travel switch 59 can also be connected. When the travel switch 59 receives a travel signal, it immediately stops the operation of the semiconductor refrigeration chip 45 through the controller 61.

[0042] Working principle:

[0043] When using the present invention, first, the entire device is installed through the fixing component 2. By rotating and adjusting the angles of the two movable blocks 23 on the round rod 22, the rotation angle of the entire device can be installed, or the connection lengths of the upper and lower movable blocks 23 with the inner wall of the switch cabinet are different, and the entire device can be installed at an inclined angle;

[0044] After the device is installed, the device is powered through interface 62, and then the device is controlled through controller 61 to start condensation assembly 4. The four thermoelectric coolers 45 operate to capture the water vapor-containing air entering the housing 1 through round hole 12, condense it into beads, and convert it into water droplets. When capturing external air through round hole 12, three first fans 13 can also be started to quickly suck the external air into housing 1. When the water vapor condenses into water droplets, they will continuously fall downward under the influence of gravity into collection box 51;

[0045] When thermoelectric cooler 45 is operating, a large amount of heat will also be generated. This part of the heat will be dissipated through heat sink 41 and heat pipe 42. At this time, when starting the upper and lower groups of second fans 44, the hot air containing heat can also be blown out up and down. In addition, part of the heat can be transferred to the metal housing 1 through copper sheet 43 to expand the heat dissipation area;

[0046] During the process of the upper and lower groups of second fans 44 blowing out the hot air, the regulating assembly 3 can also be started to ensure that the flow direction of the hot air will not be recycled into housing 1 by the first fans 13 again. When the travel of the telescopic rod 37 increases, it will push the round shaft 34 to rotate and displace forward a certain distance through the multiple elliptical grooves 36 opened in the long strip 35. At this time, the multiple blades 32 will rotate clockwise and open in the rectangular frame 31. At this time, the hot air will be blown to the front side of housing 1 at an oblique angle. By adjusting the position of the telescopic rod 37, the air outlet angle can be controlled;

[0047] When the water droplets are continuously collected after passing through collection box 51, they will be directly discharged from the bottom side of the tee 53. If the hose connected to the outside of the tee 53 is blocked and the water flow cannot be discharged, the liquid will first continuously accumulate and rise in the tee 53 from the blocked place until it uniformly flows upward through the round groove 54 into the water collecting shell 55 and pushes the floating buoy 56 to float upward. A small float level switch is installed in the water collecting shell 55. When the water storage volume in the water collecting shell 55 reaches 75% of the internal space of the shell, the magnetic reed switch of the small float will be turned on, and the buzzer in the controller 61 will send out an alarm signal to effectively warn the user. At this time, the floating buoy 56 will also push against the roller 58 to transmit the displacement signal to the travel switch 59. When the travel switch 59 receives the travel signal, it will immediately stop the operation of the thermoelectric cooler 45 through the controller 61. At this time, some of the water droplets still attached to the back of the collection box 51 will continue to be poured into the water collecting shell 55 with redundant space through the tee 53 until the blocked hose is unblocked.
