The ends of the snap-fit ​​members 32 have rounded corners and are disposed in the insertion groove. The spring 33 is disposed between the two snap-fit ​​members 32.

[0027] Specifically, when installing the conveying assembly 1, a sealing assembly 2 can be installed on the conveying assembly 1. By installing both seal A 21 and seal B 22 on the conveying assembly 1, moisture in the soil can be prevented from penetrating into the conveying assembly 1, thus preventing the conveying assembly 1 from rusting or corroding. In the specific installation, a fixing member 31 can be installed on seal A 21, and two snap-fit ​​members 32 can be installed on seal B 22. During installation, the snap-fit ​​members 32 can be placed in the insertion groove opened on the fixing member 31, so that seal A 21 and seal B 22 can be stably installed, thereby preventing the sealing assembly 2 from detaching from the conveying assembly 1 during subsequent use, which would cause corrosion of the conveying assembly 1.

[0028] In this embodiment, the conveying assembly 1 includes a conveying pipe A 11 and a conveying pipe B 13. Both conveying pipe A 11 and conveying pipe B 13 are hollow inside. The inner wall of conveying pipe A 11 and the conveying pipe B 13 are provided with threaded structures. The conveying pipe A 11 and the conveying pipe B 13 are threadedly connected.

[0029] Specifically, when setting up delivery pipe A 11 and delivery pipe B 13, threaded structures can be set inside delivery pipe A 11 and on delivery pipe B 13, so that the two can be stably connected.

[0030] In this embodiment, the conveying assembly 1 further includes an A flange 12, a B flange 14, and an A sealing rubber component 15. The A flange 12 and the B flange 14 are respectively disposed on the A conveying pipe 11 and the B conveying pipe 13, and the A sealing rubber component 15 is disposed on the B conveying pipe 13.

[0031] Specifically, in order to enable A conveying pipe 11 and B conveying pipe 13 to be connected to external pipes or equipment during use, A flange 12 and B flange 14 can be installed on them.

[0032] In this embodiment, the B conveying pipe 13 includes a conveying part 131 and a connecting part 132. The connecting part 132 is disposed at the end of the conveying part 131, and a threaded structure is disposed on the connecting part 132. The A sealing rubber component 15 is sleeved on the connecting part 132, and the A sealing rubber component 15 is disposed between the A conveying pipe 11 and the conveying part 131.

[0033] Specifically, during installation, the B conveying pipe 13 can be divided into two parts: a conveying part 131 and a connecting part 132. In use, the connecting part 132 is placed at the end of the conveying part 131, a threaded structure is placed on the connecting part 132, and the A sealing rubber part 15 is sleeved on the connecting part 132. The connecting part 132 is threaded inside the A conveying pipe 11, so that the A sealing rubber part 15 can be placed between the A conveying pipe 11 and the conveying part 131, thereby preventing leakage during conveying.

[0034] In this embodiment, seal A 21 is disposed on conveying pipe A 11, and seal B 22 is disposed on conveying section 131.

[0035] Specifically, in use, seal A 21 can be set on conveying pipe A 11 and seal B 22 can be set on conveying part 131, so that when conveying pipe A 11 and conveying pipe B 13 are set, seal A 21 and seal B 22 can be engaged with each other, thereby allowing the sealing assembly 2 to be set stably.

[0036] In this embodiment, the control component 4 includes an output gear 44 and a rack 45. There are two racks 45, and the two racks 45 are respectively disposed on two snap-fit ​​members 32. The two racks 45 are symmetrically arranged. The output gear 44 is disposed on the fixing member 31, and both racks 45 mesh with the output gear 44.

[0037] Specifically, when connecting the snap-fit ​​member 32 to the fixing member 31, in order to facilitate the subsequent separation of the two, an output gear 44 can be rotatably connected to the fixing member 31, and a rack 45 is provided on the snap-fit ​​member 32. By meshing the two racks 45 with the output gear 44, the output gear 44 can be rotated to drive the two snap-fit ​​members 32 to move closer or further apart, thereby allowing the snap-fit ​​member 32 to separate from the fixing member 31.

[0038] In this embodiment, the control component 4 also includes a motor 41, an A drive gear 42, and a B drive gear 43. The motor 41 is mounted on the fixing member 31, the A drive gear 42 is mounted on the output end of the motor 41, and the B drive gear 43 is mounted on the output gear 44.

[0039] Specifically, in practical use, in order to automatically control the rotation of the output gear 44, a motor 41 can be installed on the fixing part 31, and the A drive gear 42 is installed at the output end of the motor 41, and the B drive gear 43 is installed on the output gear 44. The A drive gear 42 and the B drive gear 43 are meshed, so that the output gear 44 can be driven to rotate by starting the motor 41.

[0040] The working principle and usage process of this utility model are as follows: When installing the conveying component 1, a sealing component 2 can be set on the conveying component 1. By tightly setting the sealing component 2 to the conveying component 1, it is possible to prevent water in the soil from entering the conveying component 1 during subsequent use, thereby preventing corrosion or rust on the surface or inside of the conveying component 1. In order to ensure that the sealing component 2 can be set stably, a connecting component 3 can be set on the sealing component 2. The connecting component 3 can stably set the sealing component 2, thereby preventing external water from entering the interior of the sealing component 2. A control component 4 is set on the connecting component 3. The control component 4 can enable the sealing component 2 to be opened quickly when it is necessary to open it later.

[0041] The electronic components and modules used in this utility model can all be parts that are commonly used in the market and can achieve the specific functions in this case. The specific models and sizes can be selected and adjusted according to actual needs.
