Description

Technical Field

[0001] The present invention relates to the technical field of outdoor terminal boxes, in particular to an outdoor terminal box with a protective structure. Background Art

[0002] Substation outdoor terminal boxes operate in humid environments year-round and are susceptible to environmental influences. In locations with large temperature swings between day and night and humid air, small water droplets are prone to forming inside the substation terminal box. If these small water droplets drip onto the operating terminal blocks, they will affect the performance of the substation terminal box, pose a safety hazard to maintenance personnel, and result in poor operating condition and lifespan of the terminal box.

[0003] The Chinese invention patent publication number CN108448513A discloses an outdoor secondary terminal box. By providing multiple side grooves on both sides of the box body and connecting multiple side panels together through connecting rods, it is possible to open any side panel and simultaneously drive multiple side panels to open automatically, achieving a function that is simple and convenient to use. The side grooves can be sealed after the side panels are covered, so that staff can seal the side grooves in bad weather. The box has breathable and waterproof functions, simple wiring, and is easy to use.

[0004] Among them, in order to improve the sealing performance of the outdoor terminal box, a sealing ring is mostly provided at the box door position. The sealing ring can effectively prevent rainwater from penetrating when the external rainfall is small. However, when the external rainfall is large, excessive rainfall will still cause penetration at the sealing ring position. This causes the sealing performance of the outdoor terminal box to decrease after long-term rainfall. In response to the above problems, the following solutions are proposed. Summary of the Invention

[0005] To solve the above technical problems, the present invention provides an outdoor terminal box with a protective structure, comprising an electrical box, a base fixedly connected to the bottom of the electrical box, a box door rotatably connected to the side wall of the electrical box, and further comprising: The protective structure is fixedly connected to the top of the electrical box and is used to receive external wind flow; The collecting structure is fixedly connected to the inner wall of the protective structure. After the protective structure receives the external wind flow, the pressure will be transmitted to the inside of the collecting structure; A stamping structure is fixedly connected to the inner wall of the protective structure to assist the flow of wind; Before use, fix the electrical box in the desired position and ensure that the protective structure faces the wind flow position.

[0006] Preferably, the protective structure comprises: A pressure assembly, the pressure assembly is fixedly connected to the inner wall of the box door through a sealing member; The closing member includes a sealing strip fixedly connected to the inner wall of the door, and a groove is formed on the side wall of the sealing strip; A support assembly, the support assembly is fixedly connected to the electrical box through a shielding member; The shielding member includes a rain shield shell fixedly connected to the top of the electrical box, and an air inlet 1 is opened on the side wall of the rain shield shell; When it rains outside, the strong wind from outside will enter the interior of the rain shield through the air inlet, and form a Venturi effect inside the collecting structure to extract the rainwater remaining inside the groove.

[0007] Preferably, the collection structure includes: The limiting component includes an inclined plate fixedly connected to the inner wall of the rain shield shell, a trumpet tube fixedly connected to the inner wall of the second air inlet, and an output pipe connected to the end of the trumpet tube away from the second air inlet; The extraction component is fixedly connected to the side wall of the electrical box through a suction piece; The suction member includes a flow tube fixedly connected to the side wall of the electrical box; Among them, the wind flow entering the rain shield shell, under the restriction of the inclined panel, enters the interior of the circulation pipe through the second air inlet, the trumpet pipe and the output pipe, and flows rapidly inside the circulation pipe.

[0008] Preferably, the stamping structure includes: A guide assembly, the guide assembly being fixedly connected to the inner wall of the flow tube; An auxiliary component, the auxiliary component is fixedly connected to the inner wall of the rain shield shell; Among them, the auxiliary components will increase the wind-receiving area of ​​the equipment. When the wind direction deviates greatly, the air will enter the interior of the circulation tube through the auxiliary components.

[0009] Preferably, the pressure assembly includes an inclined groove formed on the inner wall of the groove; Among them, rainwater that penetrates into the sealing strip will be inside the groove. Under the influence of the rainwater's own weight, the penetrated rainwater will move toward the inclined groove. Finally, restricted by the tension of the water droplets, the rainwater will move along the inclined surface of the inclined groove toward the extraction component.

[0010] Preferably, the auxiliary component includes a transmission pipe connected to the side wall of the circulation pipe, an air pump is fixedly connected to the inner wall of the rain shield, a fixing plate is fixedly connected to the inner wall of the circulation pipe, and a torsion spring plate is rotatably connected to the inner wall of the fixing plate; Among them, when the external wind force is too small, the air pump will draw external air and transmit it to the inner wall of the circulation pipe through the transmission pipe to maintain the flow speed of the gas inside the circulation pipe.

[0011] Preferably, the outer wall of the output pipe is connected to the outer wall of the flow pipe; The function of the trumpet tube is to concentrate the air entering the rain shield toward the output tube, thereby accelerating the air flow rate inside the output tube and the circulation tube.

[0012] Preferably, the extraction assembly includes a thin plate with a slit connected to the side wall of the flow tube; Among them, when rainwater reaches the outer wall of the slit thin plate along the inclined surface of the inclined groove, the air flow rate inside the circulation pipe is too fast, while the air inside the groove is in a static state. At this time, the groove will perform a Venturi effect on the outer wall of the slit thin plate, generating a small extraction force to extract the rainwater accumulated on the outer wall of the slit thin plate inward.

[0013] Preferably, the guide assembly includes a fixing rod fixedly connected to the inner wall of the flow pipe, and a tilting rod is fixedly connected to the side wall of the fixing rod; After the slit sheet extracts water, the water will slide down along the inner wall of the slit sheet. Due to the influence of water tension, the water droplets will reach the position of the fixed rod along the inclined rod and slide down along the inner wall of the fixed rod.

[0014] Preferably, one end of the transmission tube away from the circulation tube is fixedly connected to the end of the air pump; The fixing plate always releases the torsional force during use, forcing the torsion spring plate to tilt upward with the fixing plate as the center, and forcing the end of the torsion spring plate to be in close contact with the inner wall of the flow tube.

[0015] The present invention has the following beneficial effects: (1) The present invention utilizes the characteristic that the greater the rainfall, the higher the external wind speed will be. A collection structure is provided inside the device. As the rainfall increases, the external rainwater will penetrate and enter the interior of the groove, and finally accumulate on the outer wall of the flow pipe. Under the influence of water tension, it accumulates in the gap position of the slit thin plate. In this process, when the external crosswind flows, the external wind will enter the inner wall of the rain shield shell through the air inlet 1, and will be guided by the inclined panel and finally enter the interior of the flow pipe through the trumpet pipe and the output pipe. Since the inlet area of ​​the air inlet 2 is large and the output port diameter of the trumpet pipe is small, the air flow rate inside the flow pipe is accelerated, while the air inside the groove is in a static state. At this time, the groove will perform a Venturi on the outer wall of the slit thin plate. The effect is that the trumpet is the air acceleration position and the outflow port diameter at the bottom of the circulation tube is expanded. At this time, an air acceleration zone will be formed on the inner wall of the circulation tube, and the air flow rate inside the circulation tube is greater than the air flow rate inside the groove. The slit thin plate between the two sides has a large difference in flow rates on both sides, which makes the side with slow flow rate flow to the side with fast flow rate, and generates a small extraction force to extract the rainwater accumulated on the outer wall of the slit thin plate inward. Through the application of the above components, when external rainwater penetrates the sealing strip, the penetrated rainwater is effectively removed and the impact of rainwater infiltration is reduced. In addition, when the external wind flow is small, the air pump will extract external air and transmit it to the inner wall of the circulation tube through the transmission tube to maintain the flow rate of the gas inside the circulation tube.

[0016] (2) The present invention utilizes the characteristic that the infiltrated rainwater will temporarily accumulate inside the groove, and an inclined groove is set inside the device. Under the influence of the rainwater's own weight, the infiltrated rainwater will move in the direction of the inclined groove, and finally, restricted by the tension of the water droplets, the rainwater moves along the inclined surface of the inclined groove toward the slit thin plate. Through the application of the above components, it is ensured that the water droplets condensed inside the groove can effectively move toward the direction of the slit thin plate, and the rainwater will slowly penetrate the gap of the slit thin plate under the influence of the inclination angle of the inclined groove, thereby avoiding a large distance between the water droplets and the slit thin plate, which affects the extraction effect of the device.

[0017] (3) The present invention utilizes the characteristic of the slit thin plate in extracting external water droplets, and a guiding component is provided inside the device. After the slit thin plate extracts water, the water will slide down along the inner wall of the slit thin plate. Due to the influence of water tension, the water droplets will reach the position of the fixed rod along the inclined rod and slide down along the inner wall of the fixed rod. By using the above-mentioned component, the water droplets on the inner wall of the slit thin plate are prevented from accumulating on the inner wall of the slit thin plate when flowing downward, causing the gap of the slit thin plate to be blocked, thereby affecting the adsorption efficiency of the slit thin plate on external water droplets.

[0018] (4) The present invention is characterized in that the air pump accelerates the flow rate of the circulation pipe, and an auxiliary component is set inside the device. Among them, when the external wind speed is fast enough, the torsion spring plate is forced to rotate around the fixed plate under the action of its own torsion spring. At this time, the end of the torsion spring plate will contact the inner wall of the circulation pipe and block the circulation space at the top of the circulation pipe; when the air pump is replenishing the air flow, the external air pump forces the high-pressure air flow to flow from top to bottom through the transmission pipe. At this time, the high-pressure gas will push the torsion spring plate to rotate downward around the connection point as the center. At this time, the torsion spring plate will cover the port of the output pipe. Through the application of the above components, the rapid air flow entering the circulation pipe is effectively prevented from being dispersed, causing the air flow rate inside the circulation pipe to decrease.

[0025] Collection Structure 2 includes: The limiting assembly 21 includes an inclined panel 211 fixedly connected to the inner wall of the rain shield 121, a bell tube 212 fixedly connected to the inner wall of the second air inlet 123, and an output pipe 213 connected to the end of the bell tube 212 away from the second air inlet 123; The extraction component 22 is fixedly connected to the side wall of the electrical box 13 through a suction piece; The suction member includes a flow tube 221 fixedly connected to the side wall of the electrical box 13; The wind flow entering the rain shield shell 121 enters the circulation tube 221 through the second air inlet 123 , the bell tube 212 and the output tube 213 under the restriction of the inclined panel 211 , and flows rapidly inside the circulation tube 221 .

[0026] The stamping structure 3 includes: A guide assembly 31 , the guide assembly 31 being fixedly connected to the inner wall of the flow tube 221 ; Auxiliary component 32, the auxiliary component 32 is fixedly connected to the inner wall of the rain shield shell 121; The auxiliary component 32 will increase the wind-receiving area of ​​the device. When the wind direction deviates greatly, the air will enter the interior of the circulation tube 221 through the auxiliary component 32 .

[0027] For example 2, please refer to Figure 2 - Figure 11 The present invention is an outdoor terminal box with a protective structure. Based on Example 1, the pressure component 11 includes an inclined groove 113 opened on the inner wall of the groove 112; Among them, the rainwater that penetrates into the sealing strip 111 will be inside the groove 112. Under the influence of the rainwater's own weight, the penetrated rainwater will move toward the inclined groove 113. Finally, restricted by the tension of the water droplets, the rainwater will move along the inclined surface of the inclined groove 113 toward the extraction component 22.

[0028] The auxiliary assembly 32 includes a transmission pipe 321 connected to the side wall of the circulation pipe 221, an air pump 322 fixedly connected to the inner wall of the rain shield 121, a fixing plate 323 fixedly connected to the inner wall of the circulation pipe 221, and a torsion spring plate 324 rotatably connected to the inner wall of the fixing plate 323; Among them, as the rainfall increases, external rainwater will penetrate and enter the interior of the groove 112, and eventually accumulate on the outer wall of the circulation tube 221, and under the influence of water tension, accumulate in the gap position of the slit thin plate 222. In this process, when the external crosswind flows, the external wind will enter the inner wall of the rain shield shell 121 through the air inlet 122, and be guided by the inclined panel 211, and finally enter the interior of the circulation tube 221 through the trumpet 212 and the output pipe 213. Since the inlet area of ​​the air inlet 2 123 is large and the output port diameter of the trumpet 212 is small, the air flow rate inside the circulation tube 221 is accelerated at this time, while the air inside the groove 112 is in a static state. At this time, the groove 112 will perform a Venturi effect on the outer wall of the slit thin plate 222, that is, the trumpet 212 is the air acceleration position, and the outflow port diameter at the bottom position of the circulation tube 221 is expanded. At this time, an air acceleration zone will be formed on the inner wall of the circulation tube 221, and the air flow rate inside the circulation tube 221 is greater than The air flow rate inside the groove 112, and the slit thin plate 222 between the two, due to the large difference in flow rate on both sides, this causes the side with slow flow rate to circulate to the side with fast flow rate, and generates a small extraction force to extract the rainwater accumulated on the outer wall of the slit thin plate 222 inward. Through the application of the above components, when external rainwater penetrates the sealing strip 111, the penetrated rainwater is effectively removed and the impact of rainwater infiltration is reduced; in addition, when the external wind flow is small, the air pump 322 will extract external air and transmit it to the inner wall of the circulation pipe 221 through the transmission pipe 321, so as to maintain the flow rate of the gas inside the circulation pipe 221.

[0029] The outer wall of the output pipe 213 is connected to the outer wall of the flow pipe 221; The function of the bell tube 212 is to concentrate the air entering the rain shield shell 121 toward the output tube 213 , thereby accelerating the air flow speed inside the output tube 213 and the circulation tube 221 .

[0030] The extraction assembly 22 includes a thin slit plate 222 connected to the side wall of the flow tube 221; Among them, taking advantage of the fact that the infiltrated rainwater will temporarily accumulate inside the groove 112, an inclined groove 113 is provided inside the device. Under the influence of the rainwater's own weight, the infiltrated rainwater will move in the direction of the inclined groove 113. Finally, restricted by the tension of the water droplets, the rainwater moves along the inclined surface of the inclined groove 113 toward the slit thin plate 222. Through the application of the above components, it is ensured that the water droplets condensed inside the groove 112 can effectively move toward the direction of the slit thin plate 222, avoiding a large distance between the water droplets and the slit thin plate 222, which affects the extraction effect of the equipment.

[0031] The guide assembly 31 includes a fixed rod 311 fixedly connected to the inner wall of the circulation tube 221, and a tilt rod 312 fixedly connected to the side wall of the fixed rod 311; Among them, utilizing the characteristics of the above-mentioned slit thin plate 222 in extracting external water droplets, a guiding component 31 is provided inside the device, wherein, after the slit thin plate 222 extracts water, the water will slide downward along the inner wall of the slit thin plate 222, and due to the influence of water tension, the water droplets will reach the position of the fixed rod 311 along the inclined rod 312, and slide downward along the inner wall of the fixed rod 311. Through the application of the above-mentioned components, the water droplets on the inner wall of the slit thin plate 222 are prevented from accumulating on the inner wall of the slit thin plate 222 when flowing downward, causing the gap of the slit thin plate 222 to be blocked, thereby affecting the adsorption efficiency of the slit thin plate 222 on external water droplets.

[0032] One end of the transmission tube 321 away from the circulation tube 221 is fixedly connected to the end of the air pump 322; Among them, in view of the characteristic that the air pump 322 accelerates the flow rate of the circulation tube 221, an auxiliary component 32 is provided inside the equipment. Among them, when the external wind speed is fast enough, the torsion spring plate 324 is forced to rotate around the fixed plate 323 under the action of its own torsion spring. At this time, the end of the torsion spring plate 324 will contact the inner wall of the circulation tube 221 and block the circulation space at the top of the circulation tube 221; and when the air pump 322 is replenishing the airflow, the external air pump 322 forces the high-pressure airflow to flow from top to bottom through the transmission tube 321. At this time, the high-pressure gas will push the torsion spring plate 324 to rotate downward around the connection point. At this time, the torsion spring plate 324 will cover the port of the output tube 213. Through the application of the above components, the fast airflow entering the circulation tube 221 is effectively prevented from being dispersed, causing the air flow rate inside the circulation tube 221 to decrease.

[0033] A specific application of this embodiment is: before use, the electrical box 13 is first fixed at a desired position, and the air inlet 122 is ensured to face the wind flow position.

[0034] The present invention utilizes the characteristic that the greater the rainfall, the higher the external wind speed will be. A collecting structure 2 is provided inside the device. As the rainfall increases, the external rainwater will penetrate and enter the interior of the groove 112, and finally accumulate on the outer wall of the circulation tube 221. Under the influence of water tension, it accumulates in the gap position of the slit thin plate 222. In this process, when the external cross wind flows, the external wind enters the rain shield shell 121 through the air inlet 122. The inner wall of the slit plate 222 is guided by the inclined plate 211 and finally enters the interior of the circulation pipe 221 through the trumpet pipe 212 and the output pipe 213. Since the inlet area of ​​the air inlet 123 is large and the output port diameter of the trumpet pipe 212 is small, the air flow rate inside the circulation pipe 221 is accelerated at this time, while the air inside the groove 112 is in a static state. At this time, the groove 112 will perform a Venturi effect on the outer wall of the slit thin plate 222, that is, the trumpet pipe 212 is the air acceleration position, and the outflow port diameter at the bottom position of the circulation pipe 221 is expanded. At this time, the inner wall of the circulation pipe 221 will form an air acceleration zone, and the air flow rate inside the circulation pipe 221 is high. The air flow rate inside the groove 112, and the slit thin plate 222 located between the two, due to the large difference in flow rate on both sides, causes the side with slow flow rate to circulate to the side with fast flow rate, and generates a small extraction force to extract the rainwater accumulated on the outer wall of the slit thin plate 222 inward. Through the application of the above components, when external rainwater penetrates the sealing strip 111, the penetrated rainwater is effectively removed and the impact of rainwater infiltration is reduced; in addition, when the external wind flow is small, the air pump 322 will extract external air and transmit it to the inner wall of the circulation pipe 221 through the transmission pipe 321, so as to maintain the flow rate of the gas inside the circulation pipe 221.

[0035] Taking advantage of the fact that the infiltrated rainwater will temporarily accumulate inside the groove 112, an inclined groove 113 is provided inside the device. Under the influence of the rainwater's own weight, the infiltrated rainwater will move in the direction of the inclined groove 113. Finally, restricted by the tension of the water droplets, the rainwater moves along the inclined surface of the inclined groove 113 toward the slit thin plate 222. Through the application of the above components, it is ensured that the water droplets condensed inside the groove 112 can effectively move toward the slit thin plate 222, avoiding a large distance between the water droplets and the slit thin plate 222, which affects the extraction effect of the equipment.

[0036] Taking advantage of the characteristic of the above-mentioned slit thin plate 222 in extracting external water droplets, a guiding component 31 is provided inside the device, wherein, after the slit thin plate 222 extracts water, the water will slide downward along the inner wall of the slit thin plate 222, and due to the influence of water tension, the water droplets will reach the position of the fixed rod 311 along the inclined rod 312, and slide downward along the inner wall of the fixed rod 311. Through the application of the above-mentioned component, the water droplets on the inner wall of the slit thin plate 222 are prevented from accumulating on the inner wall of the slit thin plate 222 when flowing downward, causing the gap of the slit thin plate 222 to be blocked, thereby affecting the adsorption efficiency of the slit thin plate 222 on external water droplets.

[0037] Among them, in view of the characteristic that the air pump 322 accelerates the flow rate of the circulation tube 221, an auxiliary component 32 is provided inside the equipment. Among them, when the external wind speed is fast enough, the torsion spring plate 324 is forced to rotate around the fixed plate 323 under the action of its own torsion spring. At this time, the end of the torsion spring plate 324 will contact the inner wall of the circulation tube 221 and block the circulation space at the top of the circulation tube 221; and when the air pump 322 is replenishing the airflow, the external air pump 322 forces the high-pressure airflow to flow from top to bottom through the transmission tube 321. At this time, the high-pressure gas will push the torsion spring plate 324 to rotate downward around the connection point. At this time, the torsion spring plate 324 will cover the port of the output tube 213. Through the application of the above components, the fast airflow entering the circulation tube 221 is effectively prevented from being dispersed, causing the air flow rate inside the circulation tube 221 to decrease.
