[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] according to Figure 1-2 As shown, a water quality testing device for sewage pipelines in water conservancy projects includes a sewage pipeline body 1 with a connecting pipe 2. An upper baffle 4 and a lower baffle 3 are slidably installed inside the connecting pipe 2. A transmission cylinder 5 is rotatably mounted on the upper baffle 4. An inverted U-shaped plate is sleeved on the top of the transmission cylinder 5. A motor 6 is fixedly mounted on the top of the U-shaped plate. The motor 6 is a self-locking, reversible motor, which is existing technology and will not be described in detail. The top of the transmission cylinder 5 is fixedly connected to the output shaft of the motor 6. A connecting rod is slidably installed inside the transmission cylinder 5. A sealing ring that does not restrict the rotation of the connecting rod is provided between the transmission cylinder 5 and the connecting rod to restrict the flow of sewage. Entering the transmission cylinder 5, an arc-shaped groove 10 is provided on the side wall of the transmission cylinder 5. A limit post 11 is slidably installed in the arc-shaped groove 10. One end of the limit post 11 is fixedly installed on the side wall of one end of the connecting rod. The other end of the connecting rod is fixedly installed with the detector body 9. A protective mechanism is also fitted outside the detector body 9. The protective mechanism has been described in detail in the prior art, and no changes have been made here. It will not be described in detail. A cover plate 8 is installed on the top of the connecting pipe 2. Two cylinders 7 are fixedly installed on the cover plate 8 by bolts. The output shafts of the cylinders 7 are all connected to the top of the U-shaped plate by bolts. This arrangement allows for better disassembly of the cylinders 7.

[0021] A limiting plate is vertically fixedly installed on the upper baffle 4. A vertical limiting groove 12 is provided on the limiting plate. The limiting post 11 is slidably installed in the limiting groove 12. This setting can restrict the movement of the limiting post 11 and ensure that the connecting rod can move up and down.

[0022] The upper baffle 4 and the lower baffle 3 are provided with four connecting posts 13. The bottom of the connecting posts 13 is fixedly connected to the lower baffle 3, and the top of the connecting posts 13 is fixedly connected to the upper baffle 4 by fixing bolts.

[0023] The distance between the lower surface of the upper baffle 4 and the lower surface of the lower baffle 3 is the same as the diameter of the sewage pipe body 1. This arrangement ensures that when the lower baffle 3 contacts the inner wall of the sewage pipe body 1, the upper baffle 4 enters the position where the sewage pipe body 1 and the connecting pipe 2 are connected.

[0024] The upper baffle 4 and the lower baffle 3 are the same size and can be connected to the main body 1 of the sewage pipe and the connecting pipe 2. This arrangement can block sewage and play a sealing role.

[0025] The length of the connecting pipe 2 is greater than the distance between the motor 6 and the lower baffle 3. This arrangement ensures that all mechanisms on the lower baffle 3 can enter the connecting pipe 2 for maintenance.

[0026] The upper surfaces of both the upper baffle 4 and the lower baffle 3 are marked, which facilitates installation and ensures the fit between the slot 15 and the post 14. The lower surface of the lower baffle 3 is provided with a slot 15, and the inner wall of the sewage pipe body 1 is provided with a post 14. The lower baffle 3 is slidably connected to the post 14 on the inner wall of the sewage pipe body 1 through the slot 15. This arrangement can ensure the stability of the motor 6 during operation.

[0027] Working principle: During use, sewage flows from the left side to the right side of the main body 1 of the sewage pipe. The motor 6 is started, and the output shaft of the motor 6 drives the transmission cylinder 5 to rotate. The arc groove 10 on the transmission cylinder 5 drives the limiting column 11 to move. At the same time, under the limiting action of the limiting groove 12, the connecting rod of the limiting column 11 moves downward, so that the detector body 9 can penetrate to a suitable depth below the water surface, ensuring reliable detection results. When the detector body 9 needs to be repaired, the control cylinder 7 is activated. The cylinder 7 drives the U-shaped plate to move upward, and at the same time, the upper baffle 4 and the lower baffle 3 are driven to move upward. When the lower baffle 3 blocks the connection between the main body 1 of the sewage pipe and the connecting pipe 2, the cylinder 7, the top cover and the upper baffle 4 can be removed in sequence. The sewage between the upper baffle 4 and the lower baffle 3 is then pumped out by the water pump, so that the detector body 9 can be repaired.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
