[0032] The utility model will be further described in detail in combination with the drawings.

[0033] Please refer to Figures 1-6 As shown in the figure, in this embodiment, a waterproof ion pump power supply protection shell is provided, which comprises a shell 1, which is a hollow structure with openings at both ends, two fixed plates 6 are fixedly connected at the top of the shell 1, baffles 3 are rotatably connected on the two fixed plates 6, positioning plates 12 are fixedly connected on the two baffles 3, limiting holes 15 are provided through the positioning plates 12, a groove 14 is formed at the bottom of the shell 1, a screen 7 is detachably connected to the top of the groove 14, a water-absorbing resin 16 is fixedly connected in the groove 14 at the bottom of the screen 7, two sets of limiting mechanisms 9 are arranged in the groove 14 relative to the water-absorbing resin 16 to limit the limiting holes 15, the limiting mechanism 9 comprises a first wedge 91, which is slidingly arranged in the groove 14, two L-shaped rods 93, which are penetratingly and movably arranged in the shell 1, a second wedge 92 is fixedly connected to the first end of the two L-shaped rods 93, the second wedge 92 is slidingly arranged in the groove 14, the second wedge 92 abuts against the first wedge 91, a limiting rod 94 is movably arranged in the shell 1 relative to the limiting hole 15, the limiting rod 94 is fixedly connected to the second end of the L-shaped rod 93, and the limiting rod 94 is configured to limit the limiting hole 15.

[0034] Specifically, the positioning plate 12 is two pieces, each of which is provided with a limiting hole 15, and each set of limiting mechanism 9 has two second wedges 92; in the original state, the baffle 3 does not shield the opening of the shell 1, and the end of the positioning plate 12 away from the baffle 3 is located in the groove 14, and the limiting rod 94 is inserted into the limiting hole 15 for limiting; when the water flows on the top of the shell 1 along the screen 7 to the groove 14, the water-absorbing resin 16 absorbs water and expands, and due to the blocking effect of the screen 7, the expanded water-absorbing resin 16 expands in the direction of the groove 14, so that the water-absorbing resin 16 pushes the first wedge 91 to move towards the second wedge 92, thereby making the two second wedges 92 move away from each other, thereby driving the L-shaped rod 93 to move, so that the L-shaped rod 93 drives the limiting rod 94 to move away from the limiting block; when the limiting rod 94 is separated from the limiting hole 15, the baffle 3 is attached to the opening of the shell 1 under the action of its own gravity, realizing the shielding of the opening, avoiding the entry of external water into the shell 1, and the overall degree of automation is high; the water-absorbing resin 16 absorbs the water that may enter the shell 1, protects the ion pump power supply from water erosion, and ensures its normal work; at the same time, the water-absorbing resin 16 absorbs water and expands to drive the limiting mechanism 9 to realize the fixation of the baffle 3; this linkage design not only simplifies the operation, but also ensures the stable closing of the baffle 3 while preventing water, thereby enhancing the sealing and waterproof performance of the overall shell, and avoiding the phenomenon that the baffle 3 cannot fully shield the opening of the shell 1.

[0035] It should be noted that the selection of the water-absorbing resin 16 should be determined according to the actual waterproof requirement and use environment; different types of water-absorbing resin 16 have different water-absorbing performance and expansion characteristics; for example, the polyacrylic acid sodium water-absorbing resin 16 has a high water-absorbing ratio and a fast water-absorbing speed, and is suitable for occasions with high waterproof performance requirements; during use, the state of the water-absorbing resin 16 needs to be checked regularly, and when the water-absorbing resin 16 is saturated or its performance decreases, it can be replaced through the detachable screen 7 to ensure the waterproof effect of the shell; secondly, in this embodiment, the height of the fixed plate 6 is higher than the top of the shell 1, and the fixed plate 6 is installed on the top of the opening of the shell 1, which can block the water flow to a certain extent; at the same time, in order to enable the accumulated water on the top of the shell 1 to be drained onto the water-absorbing resin 16, a drainage groove can be opened on the top of the shell 1, and the opening method is a prior art.

[0036] In this embodiment, as Figure 5As shown, the end of the first wedge block 91 away from the second wedge block 92 is fixedly connected with the movable plate 18, and the movable plate 18 is movably arranged in the groove 14. The cross-sectional area of the movable plate 18 along the extension direction of the groove 14 is equal to the cross-sectional area of the water-absorbing resin 16. Specifically, by arranging the movable plate 18 with the same cross-sectional area as the water-absorbing resin 16, the pushing force of the water-absorbing resin 16 on the first wedge block 91 is more uniform and stable when the water-absorbing resin 16 swells, so as to more accurately drive the limiting mechanism 9 to work, ensure that the baffle 3 can be accurately and stably limited and fixed, and further improve the reliability of the waterproof sealing of the shell.

[0037] In the embodiment, as shown in Figure 1 , Figure 2 , Figure 4 and Figure 5 , the groove 14 between the limiting rod 94 and the second wedge block 92 is fixedly connected with the mounting plate 13. Specifically, the mounting plate 13 mainly plays a role of separation and support. On the one hand, it can reasonably separate the space where the limiting rod 94 and the second wedge block 92 are located, facilitate the installation and movement of each component, and avoid mutual interference. Meanwhile, the first wedge block 91 can be limited.

[0038] In the embodiment, as shown in Figure 5 , the end of the L-shaped rod 93 away from the second wedge block 92 is fixedly connected with the spring 17. Specifically, when the water-absorbing resin 16 swells and pushes the second wedge block 92 and the L-shaped rod to move, the spring 17 will be compressed. Once the water-absorbing resin 16 shrinks due to water loss or other conditions, the spring 17 will pull the L-shaped rod, the second wedge block 92 and other related components back by its own elastic restoring force, so as to restore the entire limiting mechanism 9 to the initial state or a state relatively close to the initial state. In this way, the subsequent action according to the water absorption of the water-absorbing resin 16 can be performed again. It should be noted that the water-absorbing resin 16 can be dried by air drying, oven drying or the like to discharge the water in the water-absorbing resin 16.

[0039] In the embodiment, as shown in Figure 1 , Figure 3 and Figure 6As shown, the baffle 3 is fixedly connected with at least one clamping ring 5, the opening of the shell 1 is inlaid with an equal number of clamping grooves 10 relative to the clamping ring 5, and two clamping plates 8 limiting the clamping ring 5 are fixedly connected in the clamping grooves 10. The clamping plates 8 and the clamping ring 5 are both made of spring steel 17, and specifically, when the baffle 3 is closed, the clamping ring 5 on the baffle 3 is inserted into the clamping groove 10 at the opening of the shell 1, and the clamping plate 8 limits the clamping ring 5. Since the clamping plate 8 and the clamping ring 5 are both made of spring steel 17, they have a certain elasticity, and the clamping ring 5 will be deformed by the clamping plate 8 during insertion into the clamping groove 10. Once fully inserted, the clamping ring 5 will restore its original shape by its own elasticity and be stably limited by the clamping plate 8, thereby achieving close fitting of the baffle 3 and the opening of the shell 1, and enhancing the sealing and stability of the baffle 3 when closed.

[0040] In this embodiment, as shown in Figure 1 , Figure 3 , the end of the baffle 3 fitted with the opening of the shell 1 is fixedly connected with a rubber pad 4. Specifically, the sealing between the baffle 3 and the opening of the shell 1 is greatly enhanced by the rubber pad 4, and the intrusion of external substances, especially water, is effectively prevented by the elastic sealing effect of the rubber pad 4. In combination with other waterproof measures, the waterproof performance of the waterproof ion pump power supply protective shell is comprehensively improved.

[0041] In this embodiment, as shown in Figure 1 , Figure 3 and Figure 4 , a plurality of drainage holes 11 are provided through the shell 1 and communicate with the groove body 14, and a plurality of wire holes 2 are provided through the shell 1. Specifically, when the water absorbing resin 16 reaches a saturated state after absorbing water, the excess water can be discharged out of the shell 1 through the drainage holes 11, avoiding accumulation of water in the shell 1, which can cause the water absorbing resin 16 to fail or other problems. At the same time, a plurality of wire holes 2 are provided through the shell 1 to facilitate the passage of the ion pump power supply line through the shell, so that the ion pump power supply can be normally connected to external equipment for work.
