Technical Field
[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a waterproof cable protection pipe for water pumps. Background Technology
[0002] In water conservancy projects, water pumps are the core water conveying equipment. Their cables are exposed to humid, underwater or open-air environments for a long time, facing multiple challenges such as water flow impact, mechanical vibration and silt abrasion. Therefore, it is necessary to protect the cables of water pumps. For example, CN221380327U discloses a cable protection tube with a waterproof structure, including a first protection tube and a second protection tube. The first protection tube and the second protection tube are internally connected at one end. The surfaces of the first protection tube and the second protection tube are provided with connecting components. The surface of the connecting components is provided with waterproof components. The connecting components include a threaded sleeve, a first connecting ring and a second connecting ring. The waterproof components include an insertion ring, a glue storage cavity, a glue guide tube, a cutting blade, a sealing membrane and a glue outlet tube. The first connecting ring is fixedly sleeved on the end of the second protection tube near the first protection tube. The cable protection tube with the waterproof structure of this utility model, by setting the insertion ring, the glue guide tube, the glue storage groove and the glue outlet tube, can squeeze waterproof glue into the threaded connection gap. After the waterproof glue solidifies, it can increase the sealing and waterproof effect. However, there are shortcomings: when the protective pipe is installed on the outside of the cable line, the construction personnel need to inspect the cable line regularly, disassemble the protective pipe before the inspection, and reinstall the protective pipe after the inspection. However, the existing protective pipe is difficult to disassemble and reassemble, which makes the inspection work more complicated. Utility Model Content
[0003] The purpose of this utility model is to provide a waterproof cable protection pipe for water conservancy pumps, so as to solve the problem mentioned in the background art that when the protection pipe is installed on the outside of the cable line, the construction personnel need to inspect the cable line regularly, and the protection pipe is difficult to disassemble and install, making the inspection work cumbersome.
[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a waterproof cable protection pipe for water pumps, comprising a cable line, a protection component fixedly connected to the outside of the cable line, the protection component comprising a protection post fixedly connected to the outside of the cable line, a snap-fit groove formed in the inner cavity of the protection post, a snap-fit ball slidably connected to the inner cavity of the snap-fit groove, a positioning post fixedly connected to the outside of the protection post, a snap-fit post slidably connected to the outside of the positioning post, and a spring fixedly connected to the inner cavity of the snap-fit post, the spring being used to fix the snap-fit post and the positioning post in a fixed manner.
[0005] Furthermore, the inner cavity of the protective column is provided with a limiting groove, which is U-shaped and used to place the limiting column.
[0006] Furthermore, the inner cavity of the snap-fit post is provided with an external groove, which is U-shaped and used to add waterproof components.
[0007] Furthermore, several snap-fit balls are symmetrically arranged, with one side of each snap-fit ball being tightly attached to the outer surface of the cable line, and the side of each snap-fit ball away from the cable line being tightly attached to the inner wall of the snap-fit post.
[0008] Furthermore, the surface of the snap-fit ball is provided with an elastic buffer layer, which is made of nitrile rubber and has a thickness of 1-3mm.
[0009] Furthermore, the outer wall of the protective column is provided with anti-slip texture, which is distributed in a spiral or grid pattern.
[0010] This utility model has the following beneficial effects: I. This utility model is equipped with a snap-fit ball and a snap-fit post. The protective component first places the protective post on the outside of the cable line. Then, one side of the snap-fit ball is tightly attached to the outer surface of the cable line, and the other side is tightly attached to the inner wall of the snap-fit post. When the construction personnel move the snap-fit post to the left, the snap-fit ball is slightly offset outward due to the compression of the cable line, which facilitates the removal of the protective component. When it is necessary to fix it, the snap-fit post moves to the right due to the pressure of the spring. Then, the snap-fit post is limited by the limiting post in the limiting groove, so that its inner wall is tightly attached to the snap-fit ball, thereby fixing the protective component to the outside of the cable line. The protective component enables the protective post to be installed and removed quickly, improving the speed of cable line protection. Second, based on the above-mentioned beneficial effects, a limiting groove and an external groove are also provided. After the limiting post is inserted into the U-shaped limiting groove, it can limit the range of axial movement of the snap-fit post along the positioning post, avoid excessive compression or stretching of the spring leading to structural failure, and ensure that the snap-fit assembly is always in the effective working range. Then, the external groove is filled with sealant such as silicone rubber and polyurethane, which can fill the tiny gaps between the snap-fit post, the positioning post, and the protective post, forming a dual waterproof system of "physical barrier + chemical seal" to prevent moisture from seeping in from the component connection.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0016] Please see Figure 1-3 As shown, this utility model is a waterproof cable protection pipe for water pumps, including a cable line 1. A protection component 2 is fixedly connected to the outside of the cable line 1. The protection component 2 includes a protection post 21, which is fixedly connected to the outside of the cable line 1. The inner cavity of the protection post 21 is provided with a snap-fit groove 22. A snap-fit ball 23 is slidably connected to the inner cavity of the snap-fit groove 22. A positioning post 25 is fixedly connected to the outside of the protection post 21. A snap-fit post 26 is slidably connected to the outside of the positioning post 25. A spring 27 is fixedly connected to the inner cavity of the snap-fit post 26. The spring 27 is used to fix the snap-fit post 26 and the positioning post 25. For example, such as Figure 2 As shown, the protection component 2 first places the protection post 21 on the outside of the cable line 1. Then, one side of the snap-fit ball 23 is tightly attached to the outer surface of the cable line 1, and the other side is tightly attached to the inner wall of the snap-fit post 26. When the construction personnel move the snap-fit post 26 to the left, the snap-fit ball 23 is slightly offset outward due to the compression of the cable line 1, which makes it easier to remove the protection component 2. When it needs to be fixed, the snap-fit post 26 moves to the right due to the pressure of the spring 27. Then, the snap-fit post 26 is limited by the limiting post in the limiting groove 24, so that its inner wall is tightly attached to the snap-fit ball 23, thereby fixing the protection component 2 to the outside of the cable line 1.
[0017] Several snap-fit balls 23 are symmetrically arranged. One side of the snap-fit ball 23 is in close contact with the outer surface of the cable line 1, and the side of the snap-fit ball 23 away from the cable line 1 is in close contact with the inner wall of the snap-fit post 26. For example, when the construction worker moves the locking post 26 to the left, the locking ball 23 is slightly offset outward due to the compression of the cable line 1, which makes it easier to remove the protective component 2. When it needs to be fixed, the locking post 26 moves to the right due to the pressure of the spring 27, and then the locking post 26 is limited by the limiting post in the limiting groove 24, so that its inner wall is tightly connected to the locking ball 23.
[0018] The surface of the snap-fit ball 23 is provided with an elastic buffer layer, which is made of nitrile rubber and has a thickness of 1-3mm. For example, the buffer layer allows the snap-fit ball 23 to form a flexible contact with the outer surface of the cable, avoiding direct compression of the cable sheath by the rigid ball. This is especially suitable for thin-walled cables or high-frequency moving scenarios. The high elasticity of nitrile rubber can absorb high-frequency vibrations during pump operation, reducing the transmission of vibrations to the cable and reducing noise caused by component friction.
[0019] The outer wall of the protective post 21 is provided with anti-slip texture, which is distributed in a spiral or grid pattern; For example, spiral or grid-like patterns increase the contact friction between the protective post 21 and the mounting carrier, preventing the protective tube from shifting or falling off due to water flow impact or vibration.
[0020] Working principle: The protection component 2 first places the protection post 21 on the outside of the cable line 1. Then, one side of the clamping ball 23 is tightly attached to the outer surface of the cable line 1, and the other side is tightly attached to the inner wall of the clamping post 26. When the construction personnel move the clamping post 26 to the left, the clamping ball 23 is slightly offset outward due to the compression of the cable line 1, which makes it easier to remove the protection component 2. When it needs to be fixed, the clamping post 26 moves to the right due to the pressure of the spring 27. Then, the clamping post 26 is limited by the limiting post in the limiting groove 24, so that its inner wall is tightly attached to the clamping ball 23, thereby fixing the protection component 2 to the outside of the cable line 1.
[0021] This step, through the protection component 2, enables the protection post 21 to be installed and removed quickly, improving the speed of protecting the cable line 1.
[0022] Please see Figure 1-3 As shown, this embodiment, based on the above embodiment, also includes a limiting groove 24. The inner cavity of the protective column 21 is provided with a limiting groove 24, which is U-shaped and used to place the limiting column. For example, after the limiting post is inserted into the U-shaped limiting groove 24, it can limit the range of axial movement of the snap-fit post 26 along the positioning post 25, avoid excessive compression or stretching of the spring 27 which could lead to structural failure, and ensure that the snap-fit assembly is always in the effective working range.
[0023] The inner cavity of the snap-fit post 26 is provided with an external groove 28, which is U-shaped and used to add waterproof components; For example, the external groove 28 is filled with sealant such as silicone rubber or polyurethane, which can fill the tiny gaps between the snap-fit post 26, the positioning post 25, and the protective post 21, forming a dual waterproof system of "physical barrier + chemical seal" to prevent moisture from seeping in from the component connection.
[0024] Working principle: After the limiting post is inserted into the U-shaped limiting groove 24, it can limit the axial movement range of the snap-fit post 26 along the positioning post 25, avoid excessive compression or stretching of the spring 27 which could lead to structural failure, and ensure that the snap-fit assembly is always in the effective working range. Then, the outer groove 28 is filled with silicone rubber, polyurethane and other sealants, which can fill the tiny gaps between the snap-fit post 26, the positioning post 25 and the protective post 21, forming a double waterproof system of "physical barrier + chemical seal" to prevent moisture from seeping in from the component connection.
[0025] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
