[0028] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0029] The present application will be further described in combination with the drawings and embodiments as follows:

[0030] As Figure 4 and 5As shown in Embodiment 1, a water guide for a motor inlet cable includes a water-proof pad 41 fixedly installed on the top of the inner wall of the water guide 4. The water-proof pad 41 is annular with upper and lower grooves and a hollow interior. A water-proof cylinder 8 is movably installed inside the water guide 4, and the top of the water-proof cylinder 8 is in contact with the water-proof pad 41. The connection between the bottom of the water-proof pad 41 and the top of the water-proof cylinder 8 is sealed with waterproof tape. Figure 5 It can be seen that the top of the water guide 4 is equipped with a water-proof pad 41 through four straight rods. The water-proof pad 41 is in close contact with the water-proof cylinder 8, and the gap is sealed with waterproof tape. The connecting cable 6 enters the interior of the water-proof cylinder 8 directly through the water-proof pad 41, and the insulating jacket of the connecting cable 6 itself fills and seals the water-proof pad 41. When rainwater enters the water-proof cylinder 8, it will be blocked by the water-proof pad 41. The remaining rainwater will slide down the outer wall of the water-proof cylinder 8 into the interior of the water guide 4, and finally be discharged along the drain pipe 5. This prevents rainwater from entering the motor inlet terminal along the connecting cable 6 during rainy weather, and eliminates the occurrence of short circuits.

[0031] It should be noted that the water guide 4 and other components are located under the protection of the equipment rain shield 2. Therefore, most of the rainwater does not come into contact with the water guide 4 and the motor junction box 3. However, due to the distance between the desulfurization tower and the motor unit 1, the connecting cable 6 itself may carry rainwater in, or rain and wind may blow rainwater in obliquely, causing short circuit problems. Therefore, waterproofing is required.

[0032] like Figure 3 As shown in Embodiment 2, two spring seats 9 are fixedly installed inside the water guide 4. Each spring seat 9 has a telescopic spring 91 fixedly installed inside it. Each telescopic spring 91 has a clamp 92 fixedly installed at the end away from the spring seat 9. The clamps 92 are shaped like a "C". The water-separating cylinder 8 is movably installed inside the two clamps 92 on opposite sides. The water-separating cylinder 8 is fixed by clamping it with the two "C" shaped clamps 92. To prevent loosening, waterproof tape is used to bond the water-separating cylinder 8 to the water-separating pad 41, making it more convenient for maintenance during shutdown. When power needs to be cut off, the telescopic spring 91 can be retracted by pressing the clamps 92 to separate it from the water-separating cylinder 8. At the same time, after the water-separating cylinder 8 is separated from the water guide 4, one end of the connecting cable 6 can be taken out for easy maintenance and replacement of components.

[0033] Working principle: The rain shield 2 of the equipment blocks most of the rainwater from affecting the motor unit 1 and the motor junction box 3. At the same time, the connecting cable 6 is routed from inside the water guide 4 and connected to the motor junction box 3, ensuring that the falling rainwater and the rainwater sliding down the connecting cable 6 will not enter the motor junction box 3 along the connecting cable 6 and cause a short circuit. The falling rainwater is collected inside the water guide 4 and discharged uniformly through the drain pipe 5, effectively reducing the occurrence of short circuit accidents.

[0034] The preferred embodiments of the present application have been described above with the preferred embodiments, but are not intended to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
