An outdoor terminal box with a protective structure

Abstract

This invention relates to the field of outdoor terminal box technology and discloses an outdoor terminal box with a protective structure, including an electrical box. A base is fixedly connected to the bottom of the electrical box, and a door is rotatably connected to the side wall of the electrical box. External airflow enters the interior of the rainproof shell through an air inlet and reaches the inclined surface of a partition plate along the inner wall of the inclined panel. Then, it enters the interior of the output pipe through the inclined surface of the partition plate. Since the inlet area of ​​the air inlet is large and the cross-section of the flow pipe is small, the flow velocity inside the flow pipe is relatively fast. At this time, the air inside the groove is in a static state. The groove will exert a Venturi effect on the outer wall of the thin plate, generating a small suction force to draw the rainwater accumulated on the outer wall of the thin plate inward. When external rainwater seeps through the sealing strip, the seeping rainwater is effectively removed, reducing the impact of rainwater infiltration.

Description

Technical Field

[0001] This invention relates to the field of outdoor terminal box technology, specifically to an outdoor terminal box with a protective structure. Background Technology

[0002] Substation outdoor terminal boxes operate in a humid environment year-round and are easily affected by the external operating environment. In places with large temperature differences between day and night and high humidity, small water droplets can easily form inside the substation terminal boxes. If these water droplets fall onto the terminal blocks that are in operation, it will affect the performance of the substation terminal boxes, pose safety hazards to maintenance personnel, and lead to poor operating conditions and a shorter lifespan for the terminal boxes.

[0003] A Chinese invention patent with the public number CN108448513A discloses an outdoor secondary terminal box. By setting multiple side slots on both sides of the box body, and connecting multiple side plates together by connecting rods, it can realize that opening any side plate can simultaneously drive multiple side plates to open automatically, achieving a simple and convenient function. Moreover, the side slots can be sealed after the side plates are covered, so that the staff can seal the side slots in bad weather, which has the functions of ventilation and waterproofing. The wiring is simple and easy to use.

[0004] In order to improve the sealing performance of outdoor terminal boxes, sealing rings are mostly installed at the door positions. While the sealing rings can effectively prevent rainwater penetration when the external rainfall is small, excessive rainfall can still cause leakage at the sealing ring positions when the external rainfall is large. This leads to a decrease in the sealing performance of outdoor terminal boxes after long-term rainfall. To address the above problems, the following solutions are proposed. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides an outdoor terminal box with a protective structure, including an electrical box, a base fixedly connected to the bottom of the electrical box, and a door rotatably connected to the side wall of the electrical box, and further including:

[0006] The protective structure is fixedly connected to the top of the electrical box to receive external airflow.

[0007] The receiving structure is fixedly connected to the inner wall of the protective structure. After the protective structure receives external airflow, the pressure will be transmitted to the interior of the receiving structure.

[0008] The stamped structure is fixedly connected to the inner wall of the protective structure to assist the flow of air.

[0009] Before use, the electrical box should be fixed in the required position, and the protective structure should be oriented towards the airflow direction.

[0010] Preferably, the protective structure includes:

[0011] The pressure assembly is fixedly connected to the inner wall of the door via a closure.

[0012] The sealing element includes a sealing strip that is fixedly connected to the inner wall of the door, and the side wall of the sealing strip has a groove.

[0013] Support assembly, which is fixedly connected to the electrical box via a shielding component;

[0014] The shielding component includes a rain cover fixedly connected to the top of the electrical box, and an air inlet is provided on the side wall of the rain cover;

[0015] When it rains outside, strong winds will enter the interior of the rainproof shell through the air inlet and create a Venturi effect inside the collection structure, drawing out the rainwater remaining inside the groove.

[0016] Preferably, the collection structure includes:

[0017] The limiting component includes a sloping panel fixedly connected to the inner wall of the rain cover, a horn tube fixedly connected to the inner wall of the second air inlet, and an output tube connected through the end of the horn tube away from the second air inlet.

[0018] The extraction component is fixedly connected to the side wall of the electrical box via a suction device;

[0019] The suction device includes a flow tube fixedly connected to the side wall of the electrical box;

[0020] The airflow entering the rain cover is restricted by the sloping panel and enters the circulation pipe through the second air inlet, the horn tube, and the output tube, where it flows rapidly.

[0021] Preferably, the stamping structure includes:

[0022] The guide component is fixedly connected to the inner wall of the flow tube;

[0023] Auxiliary components are fixedly connected to the inner wall of the rain cover;

[0024] The auxiliary components will increase the air-receiving area of ​​the equipment. When there is a large deviation in the wind direction, air will enter the interior of the flow pipe through the auxiliary components.

[0025] Preferably, the pressure component includes a beveled groove formed in the inner wall of the recess;

[0026] The rainwater that has seeped into the sealing strip will be inside the groove. Due to the weight of the rainwater, the seeping rainwater will move towards the inclined groove. Finally, due to the tension of the water droplets, the rainwater will move along the slope of the inclined groove towards the extraction component.

[0027] Preferably, the auxiliary components include a transmission pipe that is connected through the side wall of the flow pipe, an air pump that is fixedly connected to the inner wall of the rainproof shell, a fixing plate that is fixedly connected to the inner wall of the flow pipe, and a torsion spring plate that is rotatably connected to the inner wall of the fixing plate.

[0028] When the external wind force is too low, the air pump will draw in external air and transmit it to the inner wall of the flow pipe through the transmission pipe to maintain the flow speed of the gas inside the flow pipe.

[0029] Preferably, the outer wall of the output pipe is connected to the outer wall of the flow pipe.

[0030] The function of the horn tube is to concentrate the air entering the rain cover towards the output tube, thereby accelerating the airflow speed inside the output tube and the flow tube.

[0031] Preferably, the extraction component includes a thin plate with a slit connected through the sidewall of the flow tube;

[0032] When rainwater reaches the outer wall of the slit plate along the inclined surface of the groove, the air velocity inside the flow pipe is too fast, while the air inside the groove is in a static state. At this time, the groove will exert a Venturi effect on the outer wall of the slit plate, generating a small suction force to draw the rainwater accumulated on the outer wall of the slit plate inward.

[0033] Preferably, the guiding component includes a fixed rod fixedly connected to the inner wall of the flow tube, and an inclined rod fixedly connected to the side wall of the fixed rod;

[0034] In this process, after the water is extracted from the slit plate, the water will slide down along the inner wall of the slit 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.

[0035] Preferably, the end of the transmission pipe furthest from the flow pipe is fixedly connected to the end of the air pump;

[0036] During use, the fixing plate continuously releases torsional force, forcing the torsion spring plate to tilt upwards around the fixing plate and forcing the end of the torsion spring plate to fit tightly against the inner wall of the flow pipe.

[0037] The present invention has the following beneficial effects:

[0038] (1) This invention utilizes the characteristic that the external wind speed will increase accordingly when the rainfall is greater. A collection structure is set inside the equipment. As the rainfall increases, the external rainwater will seep in and enter the interior of the groove, and eventually accumulate on the outer wall of the flow pipe. Under the influence of water tension, it will accumulate at the gap of the thin plate. During this process, when the external crosswind is flowing, the external wind will enter the inner wall of the rainproof shell through the air inlet one. Guided by the inclined panel, it will eventually enter the interior of the flow pipe through the horn tube and the output tube. Since the inlet area of ​​the air inlet two is large and the output port diameter of the horn tube is small, the air velocity inside the flow pipe is accelerated, while the air inside the groove is in a static state. At this time, the groove will venturi-likely cause the water to flow through the outer wall of the thin plate. The effect is that the horn tube is the air acceleration point, and the outlet diameter at the bottom of the flow tube is enlarged. At this time, an air acceleration zone will be formed on the inner wall of the flow tube. The air velocity inside the flow tube is greater than the air velocity inside the groove. Due to the large difference in velocity between the two sides of the thin plate in the gap, the slower flow will flow to the faster flow, generating a small suction force to draw the rainwater accumulated on the outer wall of the thin plate inward. Through the application of the above components, when external rainwater seeps through the sealing strip, the seeping rainwater is effectively removed, reducing the impact of rainwater infiltration. In addition, when the external airflow is small, the air pump will draw in external air and transmit it to the inner wall of the flow tube through the transmission pipe to maintain the airflow velocity inside the flow tube.

[0039] (2) This invention utilizes the characteristic that the infiltrated rainwater will temporarily accumulate inside the groove. An inclined groove is set inside the device. Due to the influence of the rainwater's own weight, the infiltrated rainwater will move towards the inclined groove. Finally, due to the limitation of the water droplet tension, the rainwater moves along the inclined groove towards the thin plate. Through the application of the above components, it is ensured that the water droplets condensed inside the groove can effectively move towards the thin plate. Moreover, due to the influence of the inclination angle of the inclined groove, the rainwater itself will slowly penetrate the gap of the thin plate, avoiding the water droplets being too far away from the thin plate and affecting the extraction effect of the device.

[0040] (3) The present invention utilizes the characteristics of the thin plate to extract external water droplets. A guiding component is provided inside the device. After the thin plate extracts water, the water will slide down along the inner wall of the 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. Through the application of the above component, the water droplets on the inner wall of the thin plate are prevented from accumulating on the inner wall of the thin plate when flowing downward, causing blockage of the gaps in the thin plate and affecting the adsorption efficiency of the thin plate for external water droplets.

[0041] (4) In view of the characteristic of the air pump accelerating the flow rate of the flow pipe, the present invention has an auxiliary component inside the equipment. 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 flow pipe and block the flow space at the top of the flow pipe. When the air pump replenishes the airflow, the external air pump forces the high-pressure airflow 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. At this time, the torsion spring plate will shield the port of the output pipe. Through the application of the above components, the rapid airflow entering the flow pipe is effectively prevented from dispersing, causing the air flow rate inside the flow pipe to decrease.

[0056] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0057] Example 1, please refer to Figure 1 - Figure 6 The present invention is an outdoor terminal box with a protective structure, including an electrical box 13, a base 14 fixedly connected to the bottom of the electrical box 13, and a door 15 rotatably connected to the side wall of the electrical box 13, and further including:

[0058] Protective structure 1 is fixedly connected to the top of electrical box 13 to receive external airflow;

[0059] The receiving structure 2 is fixedly connected to the inner wall of the protective structure 1. After the protective structure 1 receives external airflow, the pressure will be transmitted to the interior of the receiving structure 2.

[0060] The stamping structure 3 is fixedly connected to the inner wall of the protective structure 1 to assist the flow of air.

[0061] Before use, the electrical box 13 should be fixed in the required position, and the protective structure 1 should be oriented towards the airflow direction.

[0062] Protective structure 1 includes:

[0063] Pressure assembly 11 is fixedly connected to the inner wall of the door 15 via a closure.

[0064] The sealing element includes a sealing strip 111 fixedly connected to the inner wall of the door 15, and a groove 112 is provided on the side wall of the sealing strip 111;

[0065] Support assembly 12 includes a rain cover 121 fixedly connected to the top of the electrical box 13. An air inlet 122 is provided on the side wall of the rain cover 121, and an air inlet 123 is provided at the bottom of the rain cover 121.

[0066] When it rains outside, strong winds will enter the interior of the rainproof shell 121 through the air inlet 122 and form a Venturi effect inside the collecting structure 2, drawing out the rainwater remaining inside the groove 112.

[0067] Collection Structure 2 includes:

[0068] The limiting component 21 includes a sloping panel 211 fixedly connected to the inner wall of the rain cover 121, a horn tube 212 fixedly connected to the inner wall of the second air inlet 123, and an output tube 213 connected through the end of the horn tube 212 away from the second air inlet 123.

[0069] Extraction component 22 is fixedly connected to the side wall of electrical box 13 via a suction member;

[0070] The suction device includes a flow tube 221 that is fixedly connected to the side wall of the electrical box 13;

[0071] The airflow entering the rain cover 121 is restricted by the inclined panel 211 and enters the flow pipe 221 through the air inlet 223, the horn tube 212 and the output tube 213, and flows rapidly inside the flow pipe 221.

[0072] The stamping structure 3 includes:

[0073] Guide component 31 is fixedly connected to the inner wall of flow tube 221;

[0074] Auxiliary component 32 is fixedly connected to the inner wall of the rain cover 121;

[0075] Among them, the auxiliary component 32 will increase the wind-receiving area of ​​the equipment. When there is a large deviation in the wind direction, the air will enter the interior of the flow pipe 221 through the auxiliary component 32.

[0076] 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 a sloping groove 113 formed in the inner wall of the groove 112.

[0077] The rainwater that has seeped into the sealing strip 111 will be inside the groove 112. Due to the weight of the rainwater, the seeping rainwater will move towards the inclined groove 113. Finally, due to the tension of the water droplets, the rainwater will move along the inclined surface of the inclined groove 113 towards the extraction component 22.

[0078] The auxiliary component 32 includes a transmission pipe 321 that is connected through the side wall of the flow pipe 221, an air pump 322 that is fixedly connected to the inner wall of the rain cover 121, a fixing plate 323 that is fixedly connected to the inner wall of the flow pipe 221, and a torsion spring plate 324 that is rotatably connected to the inner wall of the fixing plate 323.

[0079] As rainfall increases, external rainwater will seep into the interior of the groove 112 and eventually accumulate on the outer wall of the flow pipe 221. Under the influence of water tension, it will also accumulate in the gaps of the thin plate 222. During this process, when there is a crosswind, the external wind will enter the inner wall of the rainproof shell 121 through the air inlet 122. Guided by the inclined panel 211, it will eventually enter the interior of the flow pipe 221 through the horn tube 212 and the outlet tube 213. Because the inlet area of ​​the second air inlet 123 is larger and the outlet diameter of the horn tube 212 is smaller, the air velocity inside the flow pipe 221 will increase, while the air inside the groove 112 will be still. At this time, the groove 112 will exert a Venturi effect on the outer wall of the thin plate 222, i.e., the horn tube 212 will be the air acceleration point, and the outlet diameter at the bottom of the flow pipe 221 will be enlarged. At this time, the inner wall of the flow pipe 221 will form an air acceleration zone, and the air velocity inside the flow pipe 221 will be greater than that of the outer wall of the thin plate 222. The airflow velocity inside the groove 112, and the thin plate 222 between them, have a large difference in flow velocity between the two sides. This causes the slower flow to flow to the faster flow, generating a small suction force that draws rainwater accumulated on the outer wall of the thin plate 222 inward. Through the application of the above components, when external rainwater seeps into the sealing strip 111, the seeping rainwater is effectively removed, reducing the impact of rainwater infiltration. In addition, when the external airflow is small, the air pump 322 will draw in external air and transmit it to the inner wall of the flow pipe 221 through the transmission pipe 321, maintaining the flow velocity of the gas inside the flow pipe 221.

[0080] The outer wall of the output pipe 213 is connected to the outer wall of the flow pipe 221.

[0081] The function of the horn tube 212 is to concentrate the air entering the rain cover 121 towards the output tube 213, thereby accelerating the airflow speed inside the output tube 213 and the flow tube 221.

[0082] Extraction assembly 22 includes a thin plate 222 with a narrow slit connected through the side wall of flow tube 221;

[0083] Taking advantage of the characteristic that infiltrated rainwater temporarily accumulates inside the groove 112, an inclined groove 113 is set inside the device. Due to the influence of the rainwater's own weight, the infiltrated rainwater will move towards the inclined groove 113. Finally, due to the limitation of water droplet tension, the rainwater moves along the inclined surface of the inclined groove 113 towards the thin slit plate 222. Through the application of the above components, it is ensured that the water droplets condensed inside the groove 112 can effectively move towards the thin slit plate 222, avoiding a large distance between the water droplets and the thin slit plate 222, which would affect the extraction effect of the device.

[0084] The guide assembly 31 includes a fixed rod 311 fixedly connected to the inner wall of the flow tube 221, and an inclined rod 312 fixedly connected to the side wall of the fixed rod 311;

[0085] Taking advantage of the ability of the thin slit plate 222 to extract external water droplets, a guiding component 31 is installed inside the device. After the thin slit plate 222 extracts water, the water will slide down the inner wall of the thin slit plate 222. 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 down the inner wall of the fixed rod 311. Through the application of the above component, the water droplets on the inner wall of the thin slit plate 222 are prevented from accumulating on the inner wall of the thin slit plate 222 when flowing downward, thus avoiding blockage of the gaps in the thin slit plate 222 and affecting the adsorption efficiency of the thin slit plate 222 for external water droplets.

[0086] The end of the transmission pipe 321 away from the flow pipe 221 is fixedly connected to the end of the air pump 322;

[0087] In response to the characteristic of the air pump 322 accelerating the flow rate of the flow pipe 221, an auxiliary component 32 is installed inside the equipment. When the external wind speed is fast enough, the torsion spring plate 324, under the action of its own torsion spring, is forced to rotate around the fixed plate 323. At this time, the end of the torsion spring plate 324 will contact the inner wall of the flow pipe 221 and block the flow space at the top of the flow pipe 221. When the air pump 322 replenishes the airflow, the external air pump 322 forces the high-pressure airflow to flow from top to bottom through the transmission pipe 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 shield the port of the output pipe 213. Through the application of the above components, the rapid airflow entering the flow pipe 221 is effectively prevented from dispersing, causing the airflow velocity inside the flow pipe 221 to decrease.

[0088] One specific application of this embodiment is: before use, fix the electrical box 13 in the required position and ensure that the air inlet 122 faces the airflow position.

[0089] This invention utilizes the characteristic that the external wind speed increases with heavier rainfall. An internal collection structure 2 is incorporated into the device. As rainfall increases, external rainwater seeps into the groove 112 and accumulates on the outer wall of the flow pipe 221. Under the influence of water tension, it also accumulates in the gaps of the thin slit plate 222. During this process, when there is crosswind, the external wind enters the rainproof shell 121 through the air inlet 122. Guided by the inclined panel 211, the airflow enters the flow pipe 221 through the horn tube 212 and the outlet tube 213. Because the inlet area of ​​the inlet 212 is large, while the outlet diameter of the horn tube 212 is small, the airflow velocity inside the flow pipe 221 increases, while the air inside the groove 112 remains stationary. At this time, the groove 112 will exert a Venturi effect on the outer wall of the thin plate 222, meaning the horn tube 212 becomes the air acceleration point, and the outlet diameter at the bottom of the flow pipe 221 expands. Therefore, the inner wall of the flow pipe 221 will form an air acceleration zone, and the airflow velocity inside the flow pipe 221 will be high. The airflow velocity inside the groove 112 and the thin plate 222 between them have a large difference in flow velocity between the two sides. This causes the slower flow to flow to the faster flow, generating a small suction force that draws rainwater accumulated on the outer wall of the thin plate 222 inward. Through the application of the above components, when external rainwater seeps into the sealing strip 111, the seeping rainwater is effectively removed, reducing the impact of rainwater infiltration. In addition, when the external airflow is small, the air pump 322 will draw in external air and transmit it to the inner wall of the flow pipe 221 through the transmission pipe 321, maintaining the flow velocity of the gas inside the flow pipe 221.

[0090] Taking advantage of the characteristic that infiltrated rainwater temporarily accumulates inside the groove 112, an inclined groove 113 is set inside the device. Due to the influence of the rainwater's own weight, the infiltrated rainwater will move towards the inclined groove 113. Finally, due to the limitation of water droplet tension, the rainwater moves along the inclined surface of the inclined groove 113 towards the thin slit plate 222. Through the application of the above components, it is ensured that the water droplets condensed inside the groove 112 can effectively move towards the thin slit plate 222, avoiding a large distance between the water droplets and the thin slit plate 222, which would affect the extraction effect of the device.

[0091] Taking advantage of the water-absorbing characteristics of the thin slit plate 222, a guiding component 31 is installed inside the device. After the thin slit plate 222 absorbs water, the water will slide down the inner wall of the thin slit plate 222. 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 down the inner wall of the fixed rod 311. Through the application of the above component, the water droplets on the inner wall of the thin slit plate 222 are prevented from accumulating on the inner wall of the thin slit plate 222 when flowing downward, thus avoiding blockage of the gaps in the thin slit plate 222 and affecting the adsorption efficiency of the thin slit plate 222 for external water droplets.

[0092] In response to the characteristic of the air pump 322 accelerating the flow rate of the flow pipe 221, an auxiliary component 32 is installed inside the equipment. When the external wind speed is fast enough, the torsion spring plate 324, under the action of its own torsion spring, is forced to rotate around the fixed plate 323. At this time, the end of the torsion spring plate 324 will contact the inner wall of the flow pipe 221 and block the flow space at the top of the flow pipe 221. When the air pump 322 replenishes the airflow, the external air pump 322 forces the high-pressure airflow to flow from top to bottom through the transmission pipe 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 shield the port of the output pipe 213. Through the application of the above components, the rapid airflow entering the flow pipe 221 is effectively prevented from dispersing, causing the airflow velocity inside the flow pipe 221 to decrease.

When the external wind force is too low, the air pump (322) will draw in the external air and transmit it to the inner wall of the flow pipe (221) through the transmission pipe (321) to maintain the flow speed of the gas inside the flow pipe (221).

4. An outdoor terminal box with a protective structure according to claim 3, characterized in that: The outer wall of the output pipe (213) is connected to the outer wall of the flow pipe (221); The function of the horn tube (212) is to concentrate the air entering the rain cover (121) towards the output tube (213) and accelerate the air flow speed inside the output tube (213) and the flow tube (221).

5. An outdoor terminal box with a protective structure according to claim 4, characterized in that: The extraction component (22) includes a thin plate (222) with a slit connected through the side wall of the flow tube (221). When rainwater reaches the outer wall of the slit plate (222) along the inclined surface of the groove (113), the air velocity inside the flow pipe (221) is too fast, while the air inside the groove (112) is in a static state. At this time, the groove (112) will perform the Venturi effect on the outer wall of the slit plate (222), generating a small suction force to draw the rainwater accumulated on the outer wall of the slit plate (222) inward.
