Description

Technical Field

[0001] The present invention relates to the technical field of PoE extenders, and particularly to a waterproof PoE extender for outdoor wall-mounted installation. Background Art

[0002] A waterproof PoE extender is a network device designed for outdoor or humid environments, used to extend Ethernet signals and power remote devices through PoE (Power over Ethernet). It usually has characteristics such as waterproof and dustproof, and is suitable for use in harsh environments. There are multiple waterproof connectors on the waterproof PoE extender, which protect the power and data connections, preventing short circuits or corrosion caused by moisture or dust. In the PoE system, the waterproof connectors ensure the stability of power and data transmission, avoiding signal interruption caused by environmental interference. Therefore, the waterproof connectors are usually threaded or snap-type, which are easy to install and can be firmly fixed to prevent loosening. However, there are usually the following problems:

[0003] First of all, most waterproof PoE extenders are installed outdoors. Therefore, the threaded or snap-type waterproof connectors need to adopt a waterproof structure. However, over time, especially in the outdoor environment, this part of the waterproof structure, such as the rubber ring, will loosen and lose its function of tightly fitting to prevent water ingress, that is, the rubber ring can no longer abut against the waterproof connector. Therefore, it is necessary to check this part of the waterproof structure in a timely manner.

[0004] Secondly, waterproof PoE extenders all adopt wall-mounted installation. This wall-mounted installation method is more likely to seep water outdoors, especially the rainwater that seeps into the connection position between the waterproof connector and the waterproof PoE extender. Therefore, it is necessary to drain this part of the remaining accumulated water in a timely manner.

[0005] Therefore, we have designed a waterproof PoE extender for outdoor wall-mounted installation. Summary of the Invention

[0036] Embodiment 1

[0037] Reference Figures 1-9, An outdoor wall-mounted waterproof PoE extender, including a waterproof PoE extender body 1. Waterproof connectors 2 are provided on both sides of the waterproof PoE extender body 1. The waterproof connectors 2 are connected to the waterproof PoE extender body 1 through jacks 5. In the PoE system, the waterproof connectors ensure the stability of power and data transmission. The waterproof PoE extender body 1 and the waterproof connectors 2 are prior arts and will not be elaborated here.

[0038] Refer to Figure 2 State, a ring-shaped water-repellent rubber band 7 is provided on the jack 5. The water-repellent rubber band 7 protrudes slightly from the inner wall of the jack 5. This setting ensures that during the process of inserting the waterproof connector 2 into the waterproof PoE extender body 1, the water-repellent rubber band 7 abuts against the outer wall of the waterproof connector 2, thus realizing the waterproof function of the water-repellent rubber band 7 for the waterproof connector 2 inside the jack 5.

[0039] Refer to Figures 5-6 State, a side wall cavity 11 is opened on the inner wall of the jack 5. The water-repellent rubber band 7 is arranged in the side wall cavity 11. An elastic toggle plate 13 for intercepting the water-repellent rubber band 7 is provided on the side wall cavity 11. It should be noted that after the water-repellent rubber band 7 is rolled up and wrapped around the expanded polystyrene, the elastic toggle plate 13 is lifted, and then the water-repellent rubber band 7 is placed according to Figure 3 State. The elastic toggle plate 13 will abut against the water-repellent rubber band 7 inside the side wall cavity 11, completing the preliminary fixing and limiting of the water-repellent rubber band 7.

[0040] During use, originally, due to the insufficient tight seal between the waterproof connector 2 and the water-repellent rubber band 7, after rain, rainwater will seep through this gap and reach inside the waterproof PoE extender body 1, and then this part of the rainwater will reach the water storage ring 8.

[0041] A water storage ring 8 coaxial with the jack 5 is provided inside the waterproof PoE extender body 1. A plurality of first water inlet holes 16 are provided on the water storage ring 8, and a water absorption sponge 15 is provided inside the water storage ring 8. The rainwater passing through between the waterproof connector 2 and the water-repellent rubber band 7 will gather at the water storage ring 8 and enter through the first water inlet holes 16. The setting of the water absorption sponge 15 can effectively prevent the rainwater from crossing the water storage ring 8, and then keep the rainwater in the water storage ring 8.

[0042] A water absorption line 14 for guiding the rainwater infiltrating into the waterproof PoE extender body 1 into the water-repellent rubber band 7 is also provided inside the jack 5. One end of the water absorption line 14 is inserted into the water absorption sponge 15, and the other end is inserted on the water-repellent rubber band 7. Therefore, for the water absorption sponge 15 that has absorbed the rainwater, the rainwater in it will guide the rainwater into the temporary storage cavity through the water absorption line 14. Therefore, when the rainwater crosses the waterproof connector 2 and the water-repellent rubber band 7, the rainwater will be guided into the water-repellent rubber band 7 through the water absorption line 14.

[0043] Refer toFigures 3-4 As shown, the two side edges of the water-proof rubber belt 7 are turned up and joined to form a temporary storage cavity. An expanded polystyrene is coated inside the water-proof rubber belt 7, and the expanded polystyrene is filled in the temporary storage cavity. It should be noted that the two side edges of the water-proof rubber belt 7 are turned up and joined. Compared with the traditional sealing setting, the water-proof rubber belt 7 absorbs water and expands, and squeezes the waterproof connector 2 to block water. This setting method not only avoids the situation that the expanded polystyrene in the temporary storage cavity absorbs water and expands to burst the water-proof rubber belt 7, but also does not prevent the expanded polystyrene from absorbing water and expanding, and pushing the water-proof rubber belt 7 to protrude more from the side wall cavity 11;

[0044] Therefore, after water seepage occurs, the expanded polystyrene in the water-proof rubber belt 7 will absorb the seeping rainwater and expand, driving the water-proof rubber belt 7 to protrude from the side wall cavity 11, and making the water-proof rubber belt 7 abut against the waterproof connector 2 again, so that the originally existing gap is filled by the expansion of the water-proof rubber belt 7, and the generated gap is squeezed, thereby realizing the water-proof function again, which can play an emergency sealing role in rainy weather for subsequent replacement.

[0045] The working principle of the present invention is as follows:

[0046] First, the waterproof connector 2 is inserted into the waterproof PoE extender body 1 through the jack 5 and fixed. The water-proof rubber belt 7 placed in the side wall cavity 11 and turning up to wrap the expanded polystyrene is used to seal the jack 5, and the water-proof rubber belt 7 abuts against the outer side wall of the waterproof connector 2.

[0047] During the use process, originally, due to the loose sealing between the waterproof connector 2 and the water-proof rubber belt 7, after rain, the rainwater will seep through this gap and reach the inside of the waterproof PoE extender body 1, and then this part of the rainwater will reach the water storage ring 8.

[0048] The rainwater passing through between the waterproof connector 2 and the water-proof rubber belt 7 will gather at the water storage ring 8 and enter through the first water inlet hole 16. The rainwater will be guided into the temporary storage cavity through the water absorption line 14. Therefore, when the rainwater crosses the waterproof connector 2 and the water-proof rubber belt 7, the rainwater will be guided into the water-proof rubber belt 7 through the water absorption line 14.

[0049] In the temporary storage cavity, the expanded polystyrene absorbs water and expands to burst the water-proof rubber belt 7, and at the same time, it does not prevent the expanded polystyrene from absorbing water and expanding, and pushing the water-proof rubber belt 7 to protrude more from the side wall cavity 11.

[0050] When the water-proof rubber belt 7 protrudes from the side wall cavity 11 and makes the water-proof rubber belt 7 abut against the waterproof connector 2 again, the originally existing gap is filled by the expansion of the water-proof rubber belt 7, and the generated gap is squeezed, thereby realizing the water-proof function again, which can play an emergency sealing role in rainy weather for subsequent replacement.

[0051] Example Two

[0052] It should be noted that referring to Figure 2 the state, the thread slot 4 is located behind the thread groove 3. Therefore, when the waterproof connector 2 is inserted into the jack 5, the thread groove 3 first crosses the jack 5, and then the thread slot 4 crosses the jack 5. Therefore, when using the threaded connection method, the thread groove 3 is installed in the jack 5, and when using the snap connection method, the thread slot 4 is installed in the jack 5.

[0053] Referring to Figure 2 the state, there are a plurality of thread blocks 6 provided on the inner wall of the jack 5, and the plurality of thread blocks 6 are arranged in a circle. There is a first movable cavity 17 provided on the inner wall of the waterproof PoE extender body 1, and a threaded rod 9 is rotationally threaded on the first movable cavity 17. The end of the threaded rod 9 is provided with a first piston 10 that moves in the first movable cavity 17. The thread block 6 telescopically moves on the inner wall of the jack 5 through the thread cavity 20. Among them, the first movable cavity 17 is filled with oil. In this way, after rotating the threaded rod 9, the first piston 10 at the end of the threaded rod 9 will be pushed to expand and contract in the first movable cavity 17. Therefore, the oil in the first movable cavity 17 will be pushed and flow.

[0054] The thread cavity 20 is connected to the first movable cavity 17 through the first communication cavity 18, and a plurality of first communication cavities 18 are communicated through the second communication cavity 19. Among them, the first communication cavity 18, the second communication cavity 19, and the thread cavity 20 are all filled with oil. Therefore, the oil pushed and flowing in the first movable cavity 17 will flow into the thread cavity 20 and push the thread block 6 to extend out of the thread cavity 20. Therefore, by rotating the threaded rod 9 to push the oil, the thread block 6 is driven to expand and contract in the jack 5.

[0055] The waterproof connector 2 is threadedly connected to the waterproof PoE extender body 1. A thread groove 3 is provided on the waterproof connector 2, and the thread groove 3 has the same pitch as the thread block 6. Therefore, when the waterproof connector 2 is inserted into the jack 5, the connection method is a threaded connection method:

[0056] During the insertion process, it is necessary to first rotate the threaded rod 9 to drive the thread block 6 in the jack 5 to extend out, and then rotate the waterproof connector 2 to make the thread groove 3 fit with the thread block 6. Therefore, the waterproof connector 2 can be screwed into the waterproof PoE extender body 1.

[0057] Example Three

[0058] The waterproof connector 2 is snap-connected to the waterproof PoE extender body 1. A plurality of thread slots 4 are provided on the waterproof connector 2, and the plurality of thread slots 4 are arranged in a circle. The thread slot 4 is adapted to the thread block 6. When the waterproof connector 2 is inserted into the jack 5, the connection method is a snap connection method:

[0059] First, insert the waterproof connector 2 into the jack 5, and then rotate the threaded rod 9. If the threaded groove 4 and the threaded block 6 are not arranged opposite to each other at this time, the threaded rod 9 cannot be rotated at this time. Then, it is necessary to rotate the waterproof connector 2, and then continue to rotate the threaded rod 9. When the threaded groove 4 on the waterproof connector 2 rotates to the relative position of the threaded block 6, the threaded rod 9 will rotate at this time, and then the threaded block 6 will extend and abut against the threaded groove 4, thus completing the snap limit between the threaded block 6 and the threaded groove 4.

[0060] Embodiment 4

[0061] Refer to Figures 5-9 In the state, a negative pressure water absorption mechanism for absorbing and storing infiltrated rainwater is further provided on the waterproof PoE extender body 1. The negative pressure water absorption mechanism is used to absorb the rainwater that seeps through the gap and reaches the inside of the waterproof PoE extender body 1, avoiding the inflow of rainwater into the waterproof PoE extender body 1 and preventing the continuous inflow of rainwater.

[0062] The negative pressure water absorption mechanism includes a water storage cavity 24 and a second movable cavity 25. The water storage cavity 24 and the second movable cavity 25 are both opened on the inner wall of the waterproof PoE extender body 1. The water storage cavity 24 is communicated with the water storage ring 8 through a second water inlet hole 23, and the water storage cavity 24 is communicated with the second movable cavity 25 through a lifting hole. It should be noted that when the rainwater absorbed in the water storage ring 8 flows into the water storage cavity 24 along the second water inlet hole 23, the preliminary collection of rainwater is completed.

[0063] The negative pressure water absorption mechanism further includes a lifting rod 28. The lifting rod 28 lifts and lowers in the lifting hole. A floating plate 31 is provided at the top of the lifting rod 28. A first water passing hole 29 is coaxially opened on the lifting rod 28, and a plurality of second water passing holes 30 communicating with the first water passing hole 29 are opened on the side wall of the lifting rod 28. Therefore, when there is no water stored in the water storage cavity 24, the lifting rod 28 descends under the action of gravity, and the second water passing hole 30 on the side wall of the lifting rod 28 is blocked by the lifting hole, thus blocking the communication between the water storage cavity 24 and the second movable cavity 25;

[0064] When the water storage cavity 24 starts to store water, due to the floating plate 31 at the top of the lifting rod 28, the liquid level in the water storage cavity 24 rises, and the buoyancy received by the floating plate 31 becomes larger and larger. Therefore, the floating plate 31 will lift the lifting rod 28 together, and the second water passing hole 30 originally blocked by the lifting hole is exposed. Since the first water passing hole 29 is communicated with the second water passing hole 30, the rainwater in the water storage cavity 24 will pass through the second water passing hole 30 and the first water passing hole 29 and reach the second movable cavity 25, thus completing the transfer of rainwater to the second movable cavity 25.

[0065] The negative pressure water absorption mechanism further includes a lifting plate 26 which moves up and down in the second moving cavity 25. The lifting plate 26 is reset and slides through a first return spring 27. Therefore, when the lifting plate 26 descends, a negative pressure will be formed in the second moving cavity 25 above the lifting plate 26, which is convenient for transferring the rainwater in the water storage cavity 24.

[0066] The negative pressure water absorption mechanism further includes a third moving cavity 32. A second piston 33 and a third piston 34 slide in the third moving cavity 32, and a second return spring 35 is connected between the second piston 33 and the third piston 34. A pressing rod 36 which abuts against the lifting plate 26 is provided at the bottom of the third piston 34. The negative pressure water absorption mechanism further includes a push plate 12 which abuts against the water-proof rubber belt 7. A piston rod 37 is provided on the push plate 12. A third communication cavity 21 and a fourth communication cavity 22 which are communicated with each other are further provided on the waterproof PoE extender body 1. The fourth communication cavity 22 is communicated with the third moving cavity 32. The piston rod 37 moves in the third communication cavity 21. Therefore, after the expanded polystyrene in the temporary storage cavity absorbs water and expands, it can not only drive the water-proof rubber belt 7 to squeeze the outer wall of the waterproof connector 2 to close the generated gap and prevent water leakage, but also push the push plate 12 and drive the piston rod 37 to move.

[0067] Wherein, the third communication cavity 21, the fourth communication cavity 22 and the third moving cavity 32 are filled with hydraulic oil. Therefore, as the push plate 12 drives the piston rod 37 to move and squeeze the hydraulic oil to drive the second piston 33 to press down, the second return spring 35 will be squeezed to press the third piston 34, and then the lifting plate 26 will be pressed down through the pressing rod 36. Therefore, a negative pressure will be formed in the second moving cavity 25 above the lifting plate 26.

[0068] It should be noted that when the pressing rod 36 presses down to squeeze the lifting plate 26, the formed negative pressure is a fixed value. And as the rainwater in the water storage cavity 24 increases, the buoyancy force on the lifting rod 28 will become larger and larger. When the buoyancy force is greater than the negative pressure suction force and the gravity of the lifting rod 28, the lifting rod 28 will rise. Therefore, the rainwater in the water storage cavity 24 will pass through the second water passing hole 30 and the first water passing hole 29 and reach the second moving cavity 25. Thus, the transfer of the rainwater to the second moving cavity 25 is completed, and then the rainwater in the second moving cavity 25 is guided out through an external guiding device to complete the drainage operation. The external guiding device uses a micro water pump and a water guide pipe to guide out the rainwater in the second moving cavity 25. The external guiding device is an existing technology and will not be elaborated here too much.

[0069] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitution or change, and should be covered within the protection scope of the present invention.
