[0002] The power tower optical cable junction box is a device used in optical fiber communication systems. It is mainly used to connect, protect and manage optical fibers in optical cables. It is installed on power tower facilities to facilitate the transmission of optical fiber signals. The power tower optical cable junction box temperature and humidity monitoring and dehumidification integrated device is a device that integrates temperature and humidity monitoring and dehumidification functions. It is mainly used to protect the optical fiber connection inside the optical cable junction box to ensure that it operates under good environmental conditions.

[0003] In order to ensure the dryness of the optical cable junction box of the power tower, a temperature and humidity monitoring and dehumidification integrated device for measuring the air humidity inside the optical cable junction box is often set in the optical cable junction box of the power tower.

The existing temperature and humidity monitoring and dehumidification integrated device often uses silica gel as a desiccant and fixes it inside the optical cable junction box to make it absorb moisture in the junction box to achieve dehumidification in the optical cable junction box of the power tower.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-10 The present invention provides a technical solution: a temperature and humidity monitoring and dehumidification integrated device for an optical cable junction box of an electric power tower, wherein a moving component 4 includes a forward and reverse motor 401, the outer surface of the forward and reverse motor 401 is fixedly connected to the inner wall of the optical cable junction box body 1 by screws, the output end of the forward and reverse motor 401 is fixedly connected to a screw rod 402, one end of the screw rod 402 is movably embedded in the inner wall of the optical cable junction box body 1, the outer surface of the screw rod 402 is threadedly sleeved with a moving block 406, the outer surface of the moving block 406 is fixedly installed with a limiting sleeve 403, and the relative position of the limiting sleeve 403 The back outer surfaces are respectively slidably connected to the relative inner walls of the optical cable junction box body 1, and the lifting base plate 404 is slidably connected between the relative inner walls of the limiting sleeve 403. A cylinder 407 is arranged near the center of the outer surface of the moving block 406, and one end of the cylinder 407 is fixedly connected to the outer surface of the lifting base plate 404. Suction fans 405 are arranged near the edges of both sides of the outer surface of the limiting sleeve 403. Telescopic rods 408 are fixedly arranged near the four corners of the inner wall of the limiting sleeve 403, and one end of the four telescopic rods 408 is fixedly connected to the outer surface of the lifting base plate 404.

[0023] In this embodiment, during the installation of the optical cable junction box of the power tower, firstly, the side provided with the adsorption component 5 is upward, and then each cable is installed in the following manner: Figure 1As shown, the interior of the multiple cable connectors arranged on the surface of the optical cable junction box body 1, when the external cable connection is completed, in order to ensure the dryness of the interior of the optical cable junction box body 1, the humidity sensor 3 is first started by the controller 2 to measure the air humidity in the optical cable junction box body 1, wherein the humidity sensor 3 is composed of two parallel electrodes and a humidity-sensitive medium in the middle. When the humidity in the air changes, the humidity-sensitive medium absorbs moisture, causing its dielectric constant to change, thereby causing a change in the capacitance value. The humidity in the air is determined by measuring the change in the capacitance value. When the humidity sensor 3 detects that the air humidity in the optical cable junction box body 1 is higher than a predetermined value, the controller 2 can be started. The forward and reverse motor 401 drives the screw rod 402 to rotate, and then drives the moving block 406 to move along the screw rod 402, so that the limiting sleeve 403 moves along the moving block 406, wherein the container composed of the limiting sleeve 403 and the lifting bottom plate 404 stores silica gel for absorbing moisture in the air, wherein silica gel is a porous material with a high specific surface area, and has a large number of tiny pores inside. The existence of these pores makes silica gel have a large surface area, which can fully contact with water molecules in the air. Water molecules are polar, and the surface of silica gel also has a certain polarity. According to the principle of like dissolves like, water molecules will be attracted by the surface of silica gel, and thus be adsorbed in the pores of silica gel. In addition, combined with Figure 3 and Figure 4 As shown, the connection grooves of the limiting sleeve 403 and the inner wall of the optical cable junction box body 1 are both in a cross shape, the purpose of which is to limit the limiting sleeve 403 while facilitating its movement. During the movement of the limiting sleeve 403, two suction fans 405 are started by the controller 2, wherein the suction fans 405 are existing mature technologies and will not be introduced in detail here. The two suction fans 405 adsorb the gas in the optical cable junction box body 1, so that the water vapor in the gas enters the interior of the limiting sleeve 403 along the small holes provided on the surface of the lifting bottom plate 404 under the adsorption effect of the suction fans 405, and contacts with multiple silica gels, so that the moisture in the air is adsorbed by the silica gel. At the same time, the limiting sleeve 403 is driven to move back and forth inside the optical cable junction box body 1 by the screw rod 402, so that the silica gel can more comprehensively adsorb the moisture retained in various places in the optical cable junction box body 1, thereby improving the dehumidification efficiency in the optical cable junction box body 1.

[0024] like Figure 1-Figure 3 and Figure 6-Figure 9As shown, a temperature and humidity monitoring and dehumidification integrated device for an optical cable junction box of an electric power tower comprises an optical cable junction box body 1, a controller 2 is arranged near one side edge of the outer surface of the optical cable junction box body 1, a humidity sensor 3 is arranged on the inner wall of the optical cable junction box body 1, a moving component 4 for removing moisture is arranged inside the optical cable junction box body 1, an adsorption component 5 is arranged on the outer surface of the optical cable junction box body 1, the adsorption component 5 comprises a hollow tube 501 and an air pump 512, a limiting rod 502 is fixedly connected between opposite inner walls of the hollow tube 501 near one end, a first spring 503 is arranged on the outer surface of the limiting rod 502, a sealing block 504 is arranged on one end of the first spring 503, a connecting pipe 505 is fixedly connected to the outer surface of the hollow tube 501 near the other end, a solenoid valve 506 is arranged on the outer surface of the connecting pipe 505 near one end, and the connecting pipe 505 is A heating wire 507 is arranged near the center of the outer surface, an air outlet pipe 508 is fixedly connected to the outer surface of the connecting tube 505, a first one-way valve 509 is arranged on the outer surface of the air outlet pipe 508, a second one-way valve 510 is arranged near the other end of the outer surface of the connecting tube 505, an infrared spectrometer 511 is arranged on the inner wall of the connecting tube 505, a connecting tube 513 is fixedly connected to the output end of the air pump 512, one end of the hollow tube 501 is fixedly connected to the outer surface of the optical cable junction box body 1, the interior of the hollow tube 501 is connected to the interior of the optical cable junction box body 1, one end of the first spring 503 is fixedly connected to the outer surface of the limit rod 502, the other end of the first spring 503 is fixedly connected to the outer surface of the sealing block 504, the outer surface of the sealing block 504 slides with the inner wall of the hollow tube 501, and one end of the connecting tube 513 is fixedly passed through the interior of the connecting tube 505.

[0025] In this embodiment, during the process of using silica gel to dehumidify the inside of the optical cable splice box body 1, when the humidity in the optical cable splice box body 1 detected by the humidity sensor 3 no longer decreases, it means that the silica gel in the limit sleeve 403 has reached a saturated state of adsorbing moisture. At this time, the forward and reverse motor 401 can be started again by the controller 2 to drive the inside of the limit sleeve 403 to move to a position that corresponds to the center of the hollow tube 501, and the hollow tube 501 is facing the center of the hollow tube 501. Figure 5The lifting bottom plate 404 is positioned at the bottom of the inclined surface as shown in the figure, and then the cylinder 407 is started to drive the lifting bottom plate 404 to move upward, thereby driving the silicone set on the lifting bottom plate 404 to move upward, wherein the four telescopic rods 408 support the lifting bottom plate 404, and through the movement of the silicone, it is convenient to adsorb the silicone later, and then the air pump 512 is started to drive the connecting pipe 513 to extract gas into the interior of the connecting pipe 505, and at the same time, the solenoid valve 506 is opened, so that the interior of the connecting pipe 505 and the hollow pipe 501 are connected. The inside of the hollow tube 501 is connected, so that the inside of the hollow tube 501 is in a negative pressure state. When the negative pressure value reaches a certain height, the sealing block 504 set in the hollow tube 501 is driven to move upward under the adsorption effect of the negative pressure, so that the first spring 503 is stretched by tension. When the sealing block 504 moves to a position in the hollow tube 501 where the inner diameter is larger than the outer diameter of the sealing block 504 under the action of the negative pressure, the inside of the hollow tube 501 is completely connected with the inside of the optical cable joint box body 1, thereby making the inside of the hollow tube 501 and the limiting The interior of the limiting sleeve 403 is connected. At this time, the silica gel placed in the limiting sleeve 403 will enter the interior of the connecting pipe 505 through the hollow tube 501 under the action of negative pressure. Among them, since the hollow tube 501 is directly opposite to the bottom of the lifting bottom plate 404, when the silica gel at the position corresponding to the hollow tube 501 is adsorbed, the silica gel set on the inclined surface of the lifting bottom plate 404 will slide downward along the inclined surface of the lifting bottom plate 404 to the position corresponding to the hollow tube 501 under the action of its own gravity. At this time, continue to start the air pump 512 until it is placed. The silica gel in the limiting sleeve 403 is completely adsorbed to the inside of the connecting pipe 505 under the action of negative pressure, and the air pump 512 can be turned off to make the air pressure in the hollow tube 501 consistent with the external atmospheric pressure. At this time, the sealing block 504 will be reset under the elastic action of the first spring 503, thereby isolating the hollow tube 501 from the inside of the optical cable junction box body 1, thereby achieving the purpose of automatically removing the saturated silica gel from the inside of the optical cable junction box body 1, and then the cylinder 407 can be started again to shorten it, driving the lifting base plate 404 to reset.

[0027] In this embodiment, after the saturated silica gel enters the connecting tube 505, the solenoid valve 506 is closed by the controller 2, and then the heating wire 507 is electrically connected to the external power supply to release heat to the outside, heat the inside of the connecting tube 505, and then heat the silica gel, so that the water in the saturated silica gel evaporates under the action of high temperature and is discharged to the outside through the air outlet pipe 508, wherein the first one-way valve 509 is used to prevent the water in the outside air from flowing back to the inside of the connecting tube 505. When the infrared spectrometer 511 detects that the water in the silica gel placed in the connecting tube 505 is completely evaporated, wherein the infrared spectrometer 511 has a light source capable of emitting continuous wavelength infrared light, which Some infrared light will irradiate the silica gel to be tested. If the silica gel contains moisture, the water molecules will absorb infrared light of specific wavelengths, so that the intensity of infrared light of these wavelengths will be weakened. The infrared light after passing through the sample will be received by the detector. The detector can measure the intensity of infrared light of different wavelengths. By comparing the intensity changes of infrared light of each wavelength before and after irradiating the sample, it can be determined whether the silica gel still contains moisture. Then the second one-way valve 510 can be opened by the controller 2, so that the silica gel in the connecting pipe 505 enters the interior of the drainage tank 601 along the inclined surface of the connecting pipe 505, thereby realizing the automatic removal of moisture in the silica gel in the temperature and humidity monitoring and dehumidification integrated device, which is convenient for the secondary use of the silica gel in the later stage.

A compression rod 602 is fixed between the walls, an electric push rod 603 is arranged on the outer surface of the compression rod 602, a piston 607 is slidably connected inside the drainage pot 601, a telescopic column 605 is fixedly installed on the outer surface of the piston 607, a second spring 606 is arranged on the outer surface of the telescopic column 605, a blocking rod 604 is fixedly connected between the relative inner walls of the drainage pot 601, one end of the telescopic column 605 is fixedly connected to the outer surface of the blocking rod 604, one end of the second spring 606 is fixedly connected to the outer surface of the piston 607, and the other end of the second spring 606 is fixedly connected to the outer surface of the blocking rod 604.

[0029] In this embodiment, when silica gel needs to be added to the interior of the optical cable junction box body 1 for dehumidification again, the electric push rod 603 is started to extend it, pushing the piston 607 to move in the direction of the blocking rod 604, so that the second spring 606 is squeezed and shortened until the piston 607 moves to a position in the drainage pot 601 where the inner diameter is larger than the outer diameter of the piston 607, thereby causing the silica gel placed in the drainage pot 601 to move downward along the arc surface of the piston 607 under the action of its own gravity to the interior of the limiting sleeve 403, wherein the drainage pot 601 is directly above the slope of the lifting bottom plate 404.

[0030] The usage and working principle of the device: During the installation of the optical cable junction box of the power tower, first, the side provided with the adsorption component 5 is facing upward, and then each cable is installed inside the multiple cable connectors on the surface of the optical cable junction box body 1. In order to ensure the dryness of the inside of the optical cable junction box body 1, first, the humidity sensor 3 is started through the controller 2 to measure the air humidity in the optical cable junction box body 1. When the humidity sensor 3 detects that the air humidity in the optical cable junction box body 1 is higher than the predetermined value, the forward and reverse motor 401 can be started through the controller 2 to drive the screw rod 402 to rotate, and then drive the moving block 406 to move along the screw rod 402, so that the limit sleeve 403 moves along the moving block 406, wherein the container composed of the limit sleeve 403 and the lifting base plate 404 stores silica gel for absorbing moisture in the air, and during the movement of the limit sleeve 403, the two suction fans 405 are started through the controller 2, and the optical cable junction box is The adsorption of the gas in the main body 1 causes the water vapor in the gas to enter the interior of the limiting sleeve 403 along the small holes provided on the surface of the lifting bottom plate 404 under the adsorption action of the suction fan 405, and contact with multiple silica gels, so that the moisture in the air is adsorbed by the silica gel. At the same time, the limiting sleeve 403 is driven to move back and forth inside the optical cable junction box main body 1 by the screw rod 402, so that the silica gel can more comprehensively adsorb the moisture retained in various places in the optical cable junction box main body 1. In the process of using silica gel to dehumidify the inside of the optical cable junction box main body 1, when the humidity in the optical cable junction box main body 1 detected by the humidity sensor 3 no longer decreases, and the air humidity in the optical cable junction box main body 1 is still high, it means that the silica gel set in the limiting sleeve 403 has reached a saturated state of adsorbing moisture, and the forward and reverse motors 401 can be started again by the controller 2 to drive the interior of the limiting sleeve 403 to move to a position corresponding to the center of the hollow tube 501, and the hollow tube 501 is directly opposite to the center of the hollow tube 501. Figure 5The lifting bottom plate 404 is moved to the lowest position of the inclined surface as shown, and then the cylinder 407 is started to drive the lifting bottom plate 404 to move upward, thereby driving the silicone set on the lifting bottom plate 404 to move upward, and then the air pump 512 is started to drive the connecting pipe 513 to extract gas into the interior of the connecting pipe 505, and at the same time, the solenoid valve 506 is opened, so that the interior of the connecting pipe 505 is connected with the interior of the hollow tube 501, so that the hollow tube 501 is in a state of negative pressure. When the negative pressure value reaches a certain height, the sealing block 504 set in the hollow tube 501 is driven to move upward under the adsorption effect of the negative pressure, so that the first spring 503 is stretched by tension. When the sealing block 504 moves to the hollow tube 501 with an inner diameter greater than that of the inner diameter under the action of the negative pressure, the sealing block 504 is moved to the hollow tube 501 with an inner diameter greater than that of the inner diameter of the inner tube 501 under the action of the negative pressure. When the outer diameter of the sealing block 504 is in the position, the interior of the hollow tube 501 is completely connected to the interior of the optical cable joint box body 1, and then the interior of the hollow tube 501 is connected to the interior of the limiting sleeve 403. At this time, the silicone placed in the limiting sleeve 403 will enter the interior of the connecting pipe 505 through the hollow tube 501 under the action of negative pressure. When the silicone at the position corresponding to the hollow tube 501 is adsorbed, the silicone set on the inclined surface of the lifting bottom plate 404 will slide downward along the inclined surface of the lifting bottom plate 404 to the position corresponding to the hollow tube 501 under the action of its own gravity. At this time, continue to start the air pump 512 until the silicone placed in the limiting sleeve 403 is completely adsorbed to the interior of the connecting pipe 505 under the action of negative pressure, and then the air pump 512 can be closed. 2, so that the air pressure in the hollow tube 501 is consistent with the external atmospheric pressure. At this time, the sealing block 504 will be reset under the elastic action of the first spring 503, thereby isolating the hollow tube 501 from the interior of the optical cable joint box body 1, and then the cylinder 407 can be started again to shorten it, driving the lifting bottom plate 404 to reset. When the saturated silica gel enters the connecting tube 505, the solenoid valve 506 is closed by the controller 2, and then the heating wire 507 is electrically connected to the external power supply to release heat to the outside, heat the inside of the connecting tube 505, and then heat the silica gel, so that the water in the saturated silica gel evaporates under the action of high temperature and is discharged to the outside through the air outlet pipe 508, wherein, through the action of the first one-way valve 509, the outside is prevented from The moisture in the air flows back to the inside of the connecting tube 505. When the infrared spectrometer 511 detects that the moisture in the silica gel placed in the connecting tube 505 is completely evaporated, the second one-way valve 510 can be opened by the controller 2, so that the silica gel in the connecting tube 505 enters the inside of the drainage tank 601 along the inclined surface of the connecting tube 505, thereby realizing the automatic removal of moisture in the silica gel in the temperature and humidity monitoring and dehumidification integrated device. When silica gel needs to be added to the inside of the optical cable junction box body 1 for dehumidification again, the electric push rod 603 is started to extend it, pushing the piston 607 to move in the direction of the blocking rod 604, so that the second spring 606 is squeezed and shortened until the piston 607 moves to the position in the drainage tank 601 where the inner diameter is larger than the outer diameter of the piston 607.Then, the silica gel placed in the drainage pot 601 moves downward along the arc surface of the piston 607 under the action of its own gravity to the inside of the limit sleeve 403, wherein the drainage pot 601 is directly above the slope of the lifting bottom plate 404. When the silica gel enters the inside of the limit sleeve 403, it will slide downward along the slope of the lifting bottom plate 404 until a certain amount of silica gel is filled into the limit sleeve 403. Then, the forward and reverse motors 401 can be started again by the controller 2 to drive the silica gel to move inside the optical cable junction box body 1 to continue to absorb the moisture inside it until the moisture in the air inside the optical cable junction box body 1 reaches the required value. Among them, the controller 2 is electrically connected to the optical cable junction box body 1, the humidity sensor 3, the forward and reverse motors 401, the suction fan 405, the cylinder 407, the solenoid valve 506, the heating wire 507, the first one-way valve 509, the second one-way valve 510, the infrared spectrometer 511, the air pump 512 and the electric push rod 603.
