Description

Technical Field

[0001] The present invention relates to the technical field of electrical equipment, in particular to an outdoor secondary terminal box. Background Art

[0002] An outdoor secondary terminal box is a switching device used in power systems to connect primary and secondary equipment. It's primarily used to switch and mark branch lines, facilitating wiring and tracing. It's typically made of stainless steel or cold-rolled steel. Stainless steel offers strong corrosion resistance and can effectively withstand harsh outdoor environments. Cold-rolled steel, on the other hand, offers superior strength and workability, while being relatively inexpensive.

[0003] In special environments, such as deserts, a sealed design is often used to reduce damage to instruments inside the box caused by sand and dust. However, due to the large temperature difference between day and night in the desert, the external ambient temperature drops to the lowest in the early morning. At this time, the phenomenon of internal heat (heat generated by the operation of electronic instruments) and external cold will occur, and eventually tiny water droplets will condense inside the box. In order to solve the above problem, the present invention provides an outdoor secondary terminal box. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides an outdoor secondary terminal box, including a main body mechanism and a base, and also including: a main body mechanism, which is installed at a required position to improve the protection and shielding of the interior by the outer shell; an opening and closing mechanism, which is installed inside the main body mechanism to control the sealing of the equipment; a scraper mechanism, which is installed inside the main body mechanism to scrape off residual water droplets inside; the top of the base is fixedly connected to a cabinet body, a plurality of sliding blocks are fixed to the inner wall of the cabinet body, a plurality of sliding blocks are fixed to the inner wall of the cabinet body, a drainage groove is opened on the inner wall of the cabinet body, a water baffle is fixedly connected to the inner wall of the cabinet body, and the outer wall of the water baffle is through-connected to the outer wall of the drainage groove.

[0005] Preferably, the main body mechanism includes: a shell component, which is fixedly connected to the inner wall of the main body mechanism for providing shielding protection; and a top component, which is fixedly connected to the inner wall of the main body mechanism for guiding water droplets condensed and dripping from the top.

[0006] Preferably, the opening and closing mechanism includes: a power assembly, which is rotatably connected to the inner wall of the main body mechanism through a power member; the power member includes a power shell fixedly connected to the inner wall of the cabinet; and an opening and closing assembly, which is fixedly connected to the outer wall of the power assembly.

[0007] Preferably, the scraper mechanism includes: a sliding assembly, which is fixedly connected to the outer wall of the power assembly; and a scraper assembly, which is fixedly connected to the inner wall of the housing assembly.

[0008] Preferably, the housing assembly includes a plurality of ventilation holes provided on both sides of the outer wall of the cabinet body, and the outer wall of the cabinet body is rotatably connected to the cabinet door.

[0009] Preferably, the top component includes a mounting bracket fixedly connected to the top of the cabinet, a bidirectional motor is fixedly connected to the outer wall of the mounting bracket, and a rotating rod is fixedly connected to the output shaft of the bidirectional motor. When the equipment is closed, since the internal temperature is higher than the outside temperature most of the time, water droplets are very easy to condense on the inner wall. When water droplets condense on the top of the equipment when the equipment is closed, a mezzanine is provided on the top of the equipment, and the water-blocking plate is connected through the drainage trough so that the water can be stably transmitted to the mezzanine. Since the temperature of the interlayer is equivalent to the internal temperature of the equipment, the water-blocking plate will not condense water. When the water droplets on the top condense and fall onto the water-blocking plate, because the water-blocking plate is set on a slope, the water droplets slide into the drainage trough and reach the bottom, thereby preventing the water droplets on the top from falling directly onto the line, thereby causing hazards such as short circuit in the line.

[0010] The transmission mechanism that this gear shifts is that the cam is connected with the gear of the driven gear, and the transmission mechanism that this gear shifts is that the cam is connected with the gear of the driven gear, and the transmission mechanism that this gear shifts is that the cam is connected with the gear of the driven gear.

[0011] Preferably, the opening and closing assembly includes a plurality of opening and closing plates fixedly connected to the inner sides of the two movable rods, the bottom of the movable rod is fixedly connected to a spring rod, the bottom of the spring rod is fixedly connected to a closing plate, the outer wall of the base is provided with a closing groove, the outer wall of the closing plate is fitly connected to the inner wall of the closing groove, and the downward force when the above-mentioned movable rod moves downward will push the spring rod and the closing plate to move downward, so that the closing plate and the bottom vent are overlapped, thereby discharging the water droplets left at the bottom of the device, and at the same time, when the movable rod moves upward, it will also drive the closing plate to move upward, thereby closing the vent, so that the interior of the device presents a relatively closed environment, avoiding the impact of bad weather and dusty areas on the internal circuits of the device.

[0012] Preferably, the sliding assembly includes several sliders 2 fixedly connected to the inner wall of the cabinet, several connecting blocks fixedly connected to the outer wall of the movable rod, and the end of the connecting block away from the movable rod is fixedly connected to the movable rod 2, and the outer wall of the movable rod 2 is engaged with the outer wall of the slider 2.

[0013] Preferably, the scraper assembly includes several fixed rods fixedly connected between the two movable rods 2, and the outer walls of the several fixed rods are fixedly connected with wiper strips, which are fitly connected to the inner wall of the cabinet. The force of the movable rod is used to move the movable rod 2 when the movable rod moves, and the movable rod 2 moves up and down. When the movable rod 2 moves, it drives the wiper strip fixedly connected to the outer wall of the fixed rod to move to scrape the inner wall of the equipment. Since the temperature inside the equipment is higher than the outside temperature most of the time, and the equipment cannot be completely sealed due to its internal sealing, there is water vapor inside. When the temperature difference is large, water droplets will condense on the side of the back plate of the equipment and the outside world, causing the water droplets to slide along the inner wall to the bottom. When the wiper strip scrapes upward, the water droplets will accumulate and flow from the drainage groove to the bottom, avoiding the water droplets from not having the drainage groove to drain when scraping upward, causing the water droplets to splash from the outside of the fixed rod to the line, causing a short circuit in the line.

[0014] The present invention has the following beneficial effects: (1) The present invention aims to solve the problem of condensation of water droplets caused by the large temperature difference between the inside and outside of the equipment in the early morning. The invention controls the rotating rod to rotate through a bidirectional motor. When the temperature of the inner wall of the equipment is too high, the bidirectional motor is controlled to work, causing the rotating rod to rotate, driving the opening and closing mechanisms on both sides to work. When gear 1 rotates driven by the belt, the teeth will move, and the movable rod will move downward with the movement of the teeth, staggered with the vents, to achieve ventilation. When the vents on both sides are opened, the airflow will effectively take away the heat of the inner wall and avoid the long-term closure of the interior of the equipment. After the temperature continues to rise, water droplets condense under the temperature difference between the inside and the outside, and eventually cause line damage.

[0015] (2) The present invention utilizes the force of the movable rod to move. When the movable rod moves, it drives the movable rod 2 to move up and down. When the movable rod 2 moves, it drives the wiper bar fixedly connected to the outer wall of the fixed rod to move and scrape the inner wall of the device. Since the temperature inside the device is higher than that of the outside most of the time, and the device cannot be completely sealed, there is water vapor inside. When the temperature difference is large, water droplets will condense on the side of the device back panel and the outside, causing the water droplets to slide along the inner wall to the bottom. When the wiper bar scrapes upward, it will accumulate the water droplets and flow them from the drainage groove to the bottom, avoiding the water droplets from not being drained by the drainage groove when scraping upward, causing the water droplets to splash from the outside of the fixed rod to the line, causing the line to short-circuit.

[0016] (3) The present invention utilizes the downward force of the movable rod when it moves. When the movable rod moves downward, it pushes the spring rod and the closing plate to move downward, so that the closing plate coincides with the bottom vent, thereby discharging the water droplets remaining at the bottom of the device. At the same time, when the movable rod moves upward, it also drives the closing plate to move upward, thereby closing the vent, making the interior of the device a relatively closed environment, and preventing the internal circuits of the device from being affected by bad weather and areas with a lot of sand and dust.

[0017] (4) When the device of the present invention is closed, since the internal temperature is higher than the external temperature most of the time, water droplets are very easy to condense on the inner wall. When water droplets condense on the top of the device in the closed state, a mezzanine is provided on the top of the device, and the water barrier is connected with the drainage groove through and through, so that the water can be stably transmitted to the mezzanine. Since the temperature of the mezzanine is equivalent to the temperature inside the device, the water barrier will not condense water. When the water droplets on the top condense and fall onto the water barrier, the water barrier is set as a slope, so that the water droplets slide into the drainage groove and reach the bottom, thereby preventing the water droplets on the top from falling directly onto the line, thereby causing hazards such as short circuit of the line.

[0023] The main body 1 includes: a shell component 11, which is fixedly connected to the inner wall of the main body 1 for providing shielding protection; a top component 12, which is fixedly connected to the inner wall of the main body 1 for guiding condensed water droplets dripping from the top.

[0025] The scraper mechanism 3 includes a sliding assembly 31 , which is fixedly connected to the outer wall of the power assembly 21 ; and a scraper assembly 32 , which is fixedly connected to the inner wall of the housing assembly 11 .

[0026] The housing assembly 11 includes a plurality of ventilation openings 113 formed on both sides of an outer wall of a cabinet body 112 . A cabinet door 114 is rotatably connected to the outer wall of the cabinet body 112 .

[0027] The top component 12 includes a mounting bracket 122 fixedly connected to the top of the cabinet 112, and a bidirectional motor 123 is fixedly connected to the outer wall of the mounting bracket 122, and a rotating rod 124 is fixedly connected to the output shaft of the bidirectional motor 123. When the equipment is closed, since the internal temperature is higher than the outside temperature most of the time, water droplets are very easy to condense on the inner wall. When water droplets condense on the top of the equipment when the equipment is in a closed state, a mezzanine is provided on the top of the equipment, and the water-blocking plate 121 is connected through the drainage groove 323 so that the water can be stably transmitted to the mezzanine. Since the temperature of the mezzanine is equivalent to the internal temperature of the equipment, the water-blocking plate 121 will not condense water. When the water droplets on the top condense and fall onto the water-blocking plate 121, because the water-blocking plate 121 is set as a slope, the water droplets slide into the drainage groove 323 and reach the bottom, thereby preventing the water droplets on the top from falling directly onto the line, thereby causing hazards such as short circuit of the line.

[0028] For example 2, please refer to Figure 5-Figure 12The present invention is an outdoor secondary terminal box. On the basis of Example 1, the power component 21 includes a rotating column 211 rotatably connected to the inner wall of the cabinet 112, the two ends of the rotating rod 124 are rotatably connected to the inner wall of the cabinet 112, the outer wall of the rotating rod 124 is rotatably connected to a belt 212, the inner wall of the power housing 218 is rotatably connected to a pulley 213, the two ends of the belt 212 away from the rotating rod 124 are rotatably connected to the outer wall of the pulley 213, the end of the pulley 213 away from the power housing 218 is fixedly connected to a gear 214, the end of the gear 214 away from the gear 214 is rotatably connected to the inner wall of the cabinet 112, the outer wall of a plurality of sliding blocks 217 is slidably connected to a movable rod 215, and the movable A plurality of teeth 216 are fixedly connected to the top of the rod 215, and the outer wall of the teeth 216 is meshed with the outer wall of the gear 1 214. When the temperature of the inner wall of the equipment is too high, the bidirectional motor 123 is controlled to work, so that the rotating rod 124 rotates, driving the opening and closing mechanisms 2 on both sides to work. When the gear 1 214 rotates driven by the belt 212, the teeth 216 will move, and the movable rod 215 will move with the movement of the teeth 216 to make the opening and closing plate 221 move downward, staggered with the vent 113, to achieve the effect of ventilation. When the vents 113 on both sides are opened, the airflow will effectively take away the heat of the inner wall stably, avoiding the long-term closure of the interior of the equipment, which will cause the temperature to continue to rise and damage the circuit.

[0029] The opening and closing assembly 22 includes a plurality of opening and closing plates 221 fixedly connected to the inner sides of the two movable rods 215, and a spring rod 222 is fixedly connected to the bottom of the movable rod 215, and a closing plate 223 is fixedly connected to the bottom of the spring rod 222. A closing groove 224 is provided on the outer wall of the base 111, and the outer wall of the closing plate 223 is fitly connected to the inner wall of the closing groove 224. By utilizing the downward force when the above-mentioned movable rod 215 moves, when the movable rod 215 moves downward, the spring rod 222 and the closing plate 223 are pushed downward, so that the closing plate 223 coincides with the bottom vent 113, thereby discharging the water droplets left at the bottom of the device. At the same time, when the movable rod 215 moves upward, the closing plate 223 is also driven to move upward, thereby closing the vent 113, so that the interior of the device presents a relatively closed environment, thereby preventing bad weather and areas with a lot of sand and dust from affecting the internal circuits of the device.

[0030] The sliding assembly 31 includes several sliders 311 fixedly connected to the inner wall of the cabinet 112, and several connecting blocks 313 fixedly connected to the outer wall of the movable rod 215. The end of the connecting block 313 away from the movable rod 215 is fixedly connected to the movable rod 2 312, and the outer wall of the movable rod 2 312 is engaged with the outer wall of the slider 311.

[0031] The scraper assembly 32 includes a plurality of fixed rods 321 fixedly connected between the two movable rods 312. The outer walls of the plurality of fixed rods 321 are fixedly connected with wiper strips 322. The wiper strips 322 are closely connected to the inner wall of the cabinet 112. The movable rod 215 moves with the force of the movable rod 215. When the movable rod 215 moves, the movable rod 312 is driven to move up and down. When the movable rod 312 moves, the wiper strips 322 fixedly connected to the outer walls of the fixed rods 321 are driven to move the inner wall of the equipment. When scraping, since the temperature inside the device is higher than the outside temperature most of the time, and the device cannot be completely sealed, there is water vapor inside. When the temperature difference is large, water droplets will condense on the side of the device back panel and the outside world, causing the water droplets to slide along the inner wall to the bottom. When the wiper strip 322 scrapes upward, the water droplets will accumulate and flow from the drainage groove 323 to the bottom, avoiding the water droplets from not having the drainage groove 323 to drain when scraping upward, causing the water droplets to splash from the outside of the fixing rod 321 onto the line, causing a line short circuit.

[0032] A specific application of this embodiment is: before use, the device is installed in the required position, and the required circuit is installed in the middle installation area of the device, away from the inner walls around the device. To address the problem of the inner wall of the device being closed and continuously heating up, the rotating rod 124 is controlled to rotate by the bidirectional motor 123. When the temperature of the inner wall of the device is too high, the bidirectional motor 123 is controlled to work, so that the rotating rod 124 rotates, driving the opening and closing mechanisms 2 on both sides to work. When the gear 1 214 rotates driven by the belt 212, the teeth 216 are moved, and the movable rod 215 moves with the movement of the teeth 216, so that the opening and closing plate 221 moves downward, staggered with the vents 113, to achieve the effect of ventilation. When the vents 113 on both sides are opened, the airflow will effectively take away the heat of the inner wall stably, avoiding the long-term closure of the interior of the device, which causes the temperature to continue to rise and damage the circuit.

[0033] By utilizing the force of the movable rod 215 moving, when the movable rod 215 moves, it will drive the movable rod 2 312 to move up and down. When the movable rod 2 312 moves, it will drive the wiper strip 322 fixedly connected to the outer wall of the fixed rod 321 to move to scrape the inner wall of the device. Since the temperature inside the device is higher than the outside temperature most of the time, the internal sealing of the device cannot be completely sealed, so there is water vapor inside. When the temperature difference is large, water droplets will condense on the side of the back plate of the device and the outside world, causing the water droplets to slide along the inner wall to the bottom. When the wiper strip 322 scrapes upward, the water droplets will accumulate and flow from the drainage groove 323 to the bottom, avoiding the water droplets from the outside of the fixed rod 321 to splash onto the line without drainage of the drainage groove 323 when scraping upward, causing the line short circuit.

[0034] By utilizing the downward force of the movable rod 215 when it moves, when the movable rod 215 moves downward, it will push the spring rod 222 and the closing plate 223 to move downward, so that the closing plate 223 coincides with the bottom vent 113, thereby discharging the water droplets remaining at the bottom of the device. At the same time, when the movable rod 215 moves upward, it will also drive the closing plate 223 to move upward, thereby closing the vent 113, making the interior of the device a relatively closed environment, avoiding the impact of bad weather and dusty areas on the internal circuits of the device.

[0035] When the equipment is closed, since the internal temperature is higher than the outside temperature most of the time, water droplets are very easy to condense on the inner wall. When water droplets condense on the top of the equipment when the equipment is closed, a mezzanine is provided on the top of the equipment, and the water-blocking plate 121 is connected through the drainage groove 323 so that the water can be stably transmitted to the mezzanine. Since the temperature of the mezzanine is equivalent to the internal temperature of the equipment, the water-blocking plate 121 will not condense water. When the water droplets on the top condense and fall onto the water-blocking plate 121, because the water-blocking plate 121 is set on a slope, the water droplets slide into the drainage groove 323 and reach the bottom, thereby preventing the water droplets on the top from falling directly onto the line, thereby causing hazards such as short circuit of the line.

[0036] The recommended motors are 42TYJ-F bidirectional controllable synchronous motors, 68KTYZ synchronous motors, etc., which are bidirectional AC motors.
