Description

Technical Field

[0001] This invention relates to the field of disconnecting switch technology, and more specifically, to an outdoor disconnecting switch and its usage method. Background Technology

[0002] A disconnecting switch is a switching device primarily used for isolating power supplies, switching operations, and connecting and disconnecting small-current circuits, without arc-extinguishing functionality. When in the open position, the disconnecting switch has a specified insulation distance between its contacts and a clear disconnection mark; when in the closed position, it can carry current under normal circuit conditions and current under abnormal conditions (such as short circuits) for a specified time.

[0003] Existing technologies disclose some patent documents with disconnecting switches. Chinese patent application number CN202123139602.X discloses a disconnecting switch, including a base, a first insulating post and a second insulating post fixed side-by-side to the base; a first terminal block disposed at the top of the first insulating post, a second terminal block disposed at the top of the second insulating post; a moving contact disposed on one side of the first terminal block, a stationary contact disposed on one side of the second terminal block; and a pair of contact blades. This invention has good safety performance, as the insulating shell and insulating layer provide insulation protection for each component of the disconnecting switch, improving safety performance and reducing the occurrence of safety accidents. The components are connected by bolts, resulting in a simple structure and convenient assembly and disassembly.

[0004] In the aforementioned patents, the waterproof and dustproof performance of the disconnect switch is poor. When using the disconnect switch outdoors, wind, sand and rain will corrode the disconnect switch, thus causing damage to the disconnect switch. Therefore, we propose an outdoor disconnect switch and its usage method. Summary of the Invention

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, the present invention aims to provide an outdoor disconnect switch and its usage method. When dust enters the protective box, the dustproof mesh effectively blocks it. However, over time, dust can clog the mesh, causing slow heat dissipation of the disconnect switch body. Slow heat dissipation also affects the use of the disconnect switch body. The invention solves the problem of excessive dust accumulation leading to poor heat dissipation by quickly replacing the dustproof mesh through a snap-fit ​​mechanism. When rainwater seeps into the protective box, it is discharged outwards through the third through-hole on the trapezoidal base plate, preventing rainwater accumulation and mold growth inside the protective box, thus solving the problem of rainwater erosion of the disconnect switch body.

[0017] The mounting mechanism is configured as two sets, both sets of which are mounted on the protective box and connected to two sets of slots.

[0018] As a preferred embodiment of the present invention, each set of the installation mechanism includes a third mounting groove, a sealing plate, a fixing component and a limiting component. The third mounting groove is opened at the side end of the protective box and is located on the lower side of the dustproof mesh plate. The sealing plate is detachably connected to the third mounting groove. The fixing component and the limiting component are both disposed in the third mounting groove.

[0019] In a preferred embodiment of the present invention, the fixing component includes a sliding plate, a plug, a screw, a nut, and a throttle. The sliding plate is slidably connected to the third mounting groove. Two plugs are provided, and both plugs are fixedly connected to the upper end of the sliding plate. The screw is rotatably connected between the upper and lower inner walls of the third mounting groove. The nut is threadedly connected to the surface of the screw and is fixedly connected to the sliding plate. The throttle is fixedly connected to the lower end of the screw and moves through the protective box.

[0020] As a preferred embodiment of the present invention, each of the limiting components includes a first spring, a guide rod, and a guide hole. Two first springs, guide rods, and guide holes are provided. The two first springs are fixedly connected between the slide plate and the third mounting groove. The two guide holes are opened at the upper end of the slide plate. The two guide rods are fixedly connected between the upper and lower inner walls of the third mounting groove, and the guide rods are slidably engaged with the two guide holes respectively.

[0021] As a preferred embodiment of the present invention, the upper inner walls of the two second mounting slots are fixedly connected with locking strips, and the upper ends of the two dustproof mesh plates are provided with locking slots, and the two locking strips are respectively movably inserted into the two locking slots.

[0022] As a preferred embodiment of the present invention, four second springs are fixedly connected to the upper end of the protective box, a top plate is fixedly connected to the four second springs, and three baffles are fixedly connected to the surface of the top plate.

[0023] As a preferred embodiment of the present invention, the upper end of the support plate has two first through holes, the bottom of the support plate is fixedly connected to a plurality of guide cones, the lower end of the protective box is fixedly connected to a trapezoidal base plate, the upper end of the trapezoidal base plate has two third through holes, the upper end of the trapezoidal base plate has a plurality of second through holes, and the two third through holes are respectively located on the left and right sides of the plurality of second through holes.

[0024] As a preferred embodiment of the present invention, the left and right inner walls of the protective box are fixedly connected with hooks, and a waterproof ring is installed in each of the two hooks, with the waterproof rings corresponding to the positions of the wire holes.

[0025] As a preferred embodiment of the present invention, a door panel is installed at the front end of the protective box, a handle is fixedly connected to the front end of the door panel, and a plurality of connectors are fixedly connected to the rear end of the protective box.

[0026] A method for using an outdoor disconnect switch includes the following steps:

[0027] S1. When using the disconnect switch body outdoors, first insert the mounting base into the first mounting slot, and then fix the mounting base to the support plate with multiple screws. At this time, the disconnect switch body is installed in the protection box. Then, the external wire passes through the wire hole into the protection box, so that the wire can be connected to the disconnect switch body. After the disconnect switch body is connected to the external wire, the circuit can be closed by controlling the disconnect switch body.

[0028] S2. When the disconnector switch body is in normal use, dust can easily enter the protection box through the heat dissipation holes. Dust entering the protection box can easily cause damage to the disconnector switch body. The dustproof mesh can effectively block dust from entering, but after a long time, dust will clog the dustproof mesh, resulting in slow heat dissipation of the disconnector switch body. Slow heat dissipation will also affect the use of the disconnector switch body. At this time, the dustproof mesh needs to be replaced. Hold the handle and turn it in reverse. The reverse rotation of the handle will drive the screw in reverse. The reverse rotation of the screw will cause the nut to move downward on the surface of the screw. The downward movement of the nut will cause the slide plate to move downward. The movement of the slide plate will drive the plug to move downward. When the plug moves downward and disengages from the slot, you can stop turning the handle. At this time, the plug is no longer engaged with the slot. When the slot and the plug are no longer engaged, the dustproof mesh can be removed. Replacing the dustproof mesh solves the problem of excessive dust accumulation inside the dustproof mesh, which leads to poor heat dissipation.

[0029] S3. In windy and rainy weather, the combination of the protective box and the door panel can effectively prevent rainwater from entering the protective box, thus protecting the main body of the disconnecting switch. After rainwater seeps into the protective box, it will be discharged outward through the third through hole and the third through hole opened on the trapezoidal base plate, preventing the accumulation of rainwater in the protective box and causing mold, thereby solving the problem of rainwater erosion of the main body of the disconnecting switch.

[0030] 3. Beneficial effects

[0031] Compared with the prior art, the advantages of this invention are:

[0032] (1) In this solution, when dust enters the protective box, the dustproof mesh can effectively block the dust from entering. However, after a long time, the dustproof mesh will be blocked by dust, which will cause the main body of the disconnecting switch to dissipate heat slowly. Slow heat dissipation will also affect the use of the main body of the disconnecting switch. The problem of poor heat dissipation caused by excessive dust accumulation in the dustproof mesh is solved by quickly replacing the dustproof mesh by snap-fit. When rainwater seeps into the protective box, it will be discharged outward through the third through hole and the third through hole opened on the trapezoidal base plate, which prevents the rainwater from accumulating in the protective box and causing mold. This solves the problem of rainwater erosion of the main body of the disconnecting switch.

[0033] (2) In this scheme, the slot is opened to facilitate the engagement with the card strip, and the depth of the slot is greater than the height of the card strip. The engagement of the slot and the card strip facilitates the upper limit of the dustproof mesh plate, which optimizes the stability of the dustproof mesh plate installation. The second spring is to facilitate the fixing of the top plate. The elasticity of the second spring plays a protective role for the protective box and can prevent the top from being hit to a certain extent. The baffle is to facilitate rain protection and prevent rainwater from directly entering the protective box.

[0034] (3) In this scheme, the first through hole is opened to facilitate the downward leakage of rainwater, the guide cone is to facilitate the flow and prevent the accumulation of rainwater, the trapezoidal base plate is to facilitate the opening of the third through hole and the second through hole, the trapezoidal base plate prevents the problem of rainwater accumulation in the trapezoidal base plate, and the drainage convenience is further optimized by the cooperation of the third through hole and the second through hole.

[0045] 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 a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0046] Example:

[0047] Please see Figure 1-8 An outdoor disconnect switch and its usage method, comprising:

[0048] Protective box 1;

[0049] Support plate 3 is fixedly connected between the left and right inner walls of the protective box 1, and a first mounting groove 5 is provided at the upper end of the support plate 3.

[0050] Mounting base 6 is movably inserted into the first mounting slot 5 and is detachably connected to the support plate 3 by multiple screws 8;

[0051] The disconnector switch body 7 is mounted on the upper end of the mounting base 6;

[0052] The heat dissipation hole 10 is provided in two parts, which are respectively opened at the left and right ends of the protective box 1. Each of the two heat dissipation holes 10 is provided with a second mounting groove 11.

[0053] Dustproof mesh 12, two dustproof mesh 12 are provided, and the two dustproof mesh 12 are respectively movably inserted into two second mounting slots 11. Each of the two dustproof mesh 12 has a set of slots 13 at its lower end, and each set of slots 13 has two slots.

[0054] There are two wire holes 34, which are respectively located at the left and right ends of the protective box 1.

[0055] In this embodiment, the support plate 3 is for facilitating the opening of the first mounting groove 5, which is for facilitating the fixing of the mounting base 6.

The second mounting groove 11 is for facilitating the installation of the dustproof mesh plate 12. The dustproof mesh plate 12 serves as a dustproof barrier and prevents rainwater from directly entering the protection box 1. The slot 13 is for facilitating the engagement with the plug 18. The dustproof mesh plate 12 is installed through the engagement of the slot 13 and the plug 18. The wire hole 34 is for facilitating the entry of the wire into the protection box 1. Inside the protective box 1, the dustproof mesh 12 can effectively block dust from entering. However, after a long time, the dustproof mesh 12 will become clogged with dust, resulting in slow heat dissipation of the disconnector switch body 7. Slow heat dissipation will also affect the use of the disconnector switch body 7. The dustproof mesh 12 can be quickly replaced by snap-fit, which solves the problem of excessive dust accumulation in the dustproof mesh 12 and poor heat dissipation. When rainwater seeps into the protective box 1, it will be discharged outward through the third through hole 35 on the trapezoidal base plate 2, preventing the accumulation of rainwater in the protective box 1 and causing mold. This solves the problem of rainwater erosion of the disconnector switch body 7.

[0056] Specifically, the installation mechanism is configured in two sets, both of which are mounted on the protective box 1 and connected to two sets of slots 13. Each set of installation mechanisms includes a third mounting slot 16, a sealing plate 25, a fixing component, and a limiting component. The third mounting slot 16 is located on the side of the protective box 1 and is situated below the dustproof mesh plate 12. The sealing plate 25 is detachably connected to the third mounting slot 16, and the fixing component and the limiting component are both located within the third mounting slot 16.

[0057] In this embodiment, the third mounting groove 16 is provided to accommodate the fixing component and the limiting component, and the sealing plate 25 is provided to protect the fixing component and the limiting component. The sealing plate 25 is detachably connected to the third mounting groove 16, and both the fixing component and the limiting component are disposed in the third mounting groove 16.

[0058] Specifically, the fixing components include a slide plate 17, a plug 18, a screw 22, a nut 23, and a throttle 24. The slide plate 17 is slidably connected to the third mounting groove 16. There are two plugs 18, both of which are fixedly connected to the upper end of the slide plate 17. The screw 22 is rotatably connected between the upper and lower inner walls of the third mounting groove 16. The nut 23 is threaded to the surface of the screw 22 and is fixedly connected to the slide plate 17. The throttle 24 is fixedly connected to the lower end of the screw 22 and moves through the protective box 1.

[0059] In this embodiment, the slide plate 17 is for fixing the insert 18, the insert 18 is for engaging with the slot 13, the screw 22 is for thread engagement with the nut 23, the screw 22 and the nut 23 are engaged to move the slide plate 17, thereby fixing the position of the slide plate 17 and the insert 18, and then installing the dustproof mesh plate 12. The throttle 24 is for rotating the screw 22.

[0060] Specifically, each limiting component includes a first spring 19, a guide rod 20, and a guide hole 21. There are two first springs 19, two guide rods 20, and two guide holes 21. The two first springs 19 are fixedly connected between the slide plate 17 and the third mounting groove 16. The two guide holes 21 are opened at the upper end of the slide plate 17. The two guide rods 20 are fixedly connected between the upper and lower inner walls of the third mounting groove 16, and the guide rods 20 slide in cooperation with the two guide holes 21 respectively.

[0061] In this embodiment, the first spring 19 further limits the sliding plate 17 through its own elasticity. The guide hole 21 is opened to facilitate the sliding of the sliding plate 17 on the surface of the guide rod 20. The sliding cooperation between the guide hole 21 and the guide rod 20 facilitates the stable movement of the sliding plate 17.

[0062] Specifically, the upper inner walls of the two second mounting slots 11 are fixedly connected with clips 15, and the upper ends of the two dustproof mesh plates 12 are provided with slots 14, with the two clips 15 being movably inserted into the two slots 14 respectively.

[0063] In this embodiment, the slot 14 is provided to facilitate engagement with the strip 15, and the depth of the slot 14 is greater than the height of the strip 15. The engagement of the slot 14 and the strip 15 facilitates the upper limit of the dustproof mesh plate 12, thereby optimizing the stability of the dustproof mesh plate 12 installation.

[0064] Specifically, four second springs 28 are fixedly connected to the upper end of the protective box 1, and a top plate 29 is fixedly connected to the four second springs 28. Three baffles 30 are fixedly connected to the surface of the top plate 29.

[0065] In this embodiment, the second spring 28 is used to facilitate fixing the top plate 29. The elasticity of the second spring 28 protects the protective box 1 and can prevent the top from being hit to a certain extent. The baffle 30 is used to facilitate rain protection and prevent rainwater from directly entering the protective box 1.

[0066] Specifically, the upper end of the support plate 3 has two first through holes 4, the bottom of the support plate 3 is fixedly connected with multiple guide cones 9, the lower end of the protective box 1 is fixedly connected with a trapezoidal base plate 2, the upper end of the trapezoidal base plate 2 has two third through holes 35, the upper end of the trapezoidal base plate 2 has multiple second through holes 36, and the two third through holes 35 are located on the left and right sides of the multiple second through holes 36 respectively.

[0067] In this embodiment, the first through hole 4 is opened to facilitate the downward leakage of rainwater, the guide cone 9 is to facilitate the flow and prevent the accumulation of rainwater, and the trapezoidal base plate 2 is to facilitate the opening of the third through hole 35 and the second through hole 36. The trapezoidal shape of the trapezoidal base plate 2 prevents the problem of rainwater accumulation inside the trapezoidal base plate 2. At the same time, the cooperation of the third through hole 35 and the second through hole 36 further optimizes the convenience of drainage.

[0068] Specifically, the left and right inner walls of the protective box 1 are fixedly connected with hooks 32, and waterproof rings 33 are installed in both hooks 32. The waterproof rings 33 correspond to the positions of the wire holes 34.

[0069] In this embodiment, the hook 32 is fixed to facilitate the installation of the waterproof ring 33. The waterproof ring 33 is for the wire to pass through. The waterproof ring 33 prevents rainwater from entering the protection box 1 through the wire, thus optimizing the waterproof effect of the disconnect switch body 7.

[0070] Specifically, a door panel 26 is installed at the front end of the protective box 1, a handle 27 is fixedly connected to the front end of the door panel 26, and multiple connectors 31 are fixedly connected to the rear end of the protective box 1.

[0071] In this embodiment, the door panel 26 is installed to facilitate sealing the protective box 1. The cooperation between the door panel 26 and the protective box 1 prevents rainwater from entering the protective box 1 and causing corrosion to the isolating switch body 7. The handle 27 is for easy pulling of the door panel 26, and the connector 31 is for easy installation of the protective box 1 by cooperating with bolts.

[0072] A method for using an outdoor disconnect switch includes the following steps:

[0073] S1. When using the disconnector switch body 7 outdoors, first insert the mounting base 6 into the first mounting slot 5, and then fix the mounting base 6 on the support plate 3 with multiple screws 8. At this time, the disconnector switch body 7 is installed in the protection box 1. Then, the external wire passes through the wire hole 34 into the protection box 1, so that the wire can be connected to the disconnector switch body 7. After the disconnector switch body 7 is connected to the external wire, the closure of the circuit can be controlled by the disconnector switch body 7.

[0074] S2. When the disconnector switch body 7 is in normal use, dust can easily enter the protection box 1 through the heat dissipation holes 10. Dust entering the protection box 1 can easily cause wear and tear on the disconnector switch body 7. The dustproof mesh plate 12 can effectively block dust from entering, but after a long time, dust will clog the dustproof mesh plate 12, resulting in slow heat dissipation of the disconnector switch body 7. Slow heat dissipation will also affect the use of the disconnector switch body 7. At this time, the dustproof mesh plate 12 needs to be replaced. Hold the handle 24 and reverse the handle 24. The reverse rotation of the handle 24 drives... When screw 22 reverses, nut 23 moves downward on the surface of screw 22. The downward movement of nut 23 causes slide plate 17 to move downward. The movement of slide plate 17 drives insert block 18 to move downward. When insert block 18 moves downward and disengages from slot 13, the throttle 24 can be stopped. At this time, insert block 18 is no longer engaged with slot 13. When slot 13 and insert block 18 are no longer engaged, dust filter plate 12 can be disassembled. Replacing dust filter plate 12 solves the problem of excessive dust accumulation in dust filter plate 12 leading to poor heat dissipation.

[0075] S3. In windy and rainy weather, the cooperation between the protective box 1 and the door panel 26 can effectively prevent rainwater from entering the protective box 1, thus protecting the disconnector switch body 7. After rainwater seeps into the protective box 1, it will be discharged outward through the third through hole 35 on the trapezoidal base plate 2, preventing the accumulation of rainwater in the protective box 1 and causing mold, thereby solving the problem of rainwater erosion of the disconnector switch body 7.

[0076] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.

Then, the external wire passes through the wire hole (34) into the protection box (1), so that the wire can be connected to the disconnect switch body (7). After the disconnect switch body (7) is connected to the external wire, the circuit can be closed by the disconnect switch body (7). S2. When the disconnector switch body (7) is in normal use, dust can easily enter the protective box (1) through the heat dissipation hole (10). Dust entering the protective box (1) can easily cause damage to the disconnector switch body (7). The dustproof mesh plate (12) can effectively block the dust from entering. However, after a long time, the dustproof mesh plate (12) will be blocked by dust, which will cause the disconnector switch body (7) to dissipate heat slowly. Slow heat dissipation will also affect the use of the disconnector switch body (7). At this time, the dustproof mesh plate (12) needs to be replaced. Hold the handle (24) and reverse the handle (24). The reverse rotation of the handle (24) will drive the screw (2) 2) Reverse rotation: The reverse rotation of the screw (22) causes the nut (23) to move downward on the surface of the screw (22). The downward movement of the nut (23) causes the slide plate (17) to move downward. The movement of the slide plate (17) drives the insert (18) to move downward. When the insert (18) moves downward and disengages from the slot (13), the throttle (24) can be stopped. At this time, the insert (18) is no longer engaged with the slot (13). When the slot (13) and the insert (18) are no longer engaged, the dust filter plate (12) can be disassembled. By replacing the dust filter plate (12), the problem of excessive dust accumulation in the dust filter plate (12) leading to poor heat dissipation is solved. S3. In windy and rainy weather, the cooperation between the protective box (1) and the door panel (26) can effectively prevent rainwater from entering the protective box (1) and protect the main body of the disconnect switch (7). After the rainwater seeps into the protective box (1), it will be discharged out through the third through hole (35) and the third through hole (35) on the trapezoidal base plate (2), preventing the rainwater from accumulating in the protective box (1) and causing mold, thus solving the problem of rainwater erosion of the main body of the disconnect switch (7).
