The scissor-type telescopic frame includes an upper rotating rod, a lower rotating rod and a plurality of middle rotating rods. The upper rotating rod is fixed at the top end of the electric push rod, the lower rotating rod is fixed on one side inner wall of the tank body, and both ends of the middle rotating rod are rotatably sleeved with a first connecting plate and a second connecting plate. One end of the first connecting plate is rotatably connected with one end of the second connecting plate. One end of one of the first connecting plates is rotatably sleeved with one end of the upper rotating rod, and one end of one of the second connecting plates is rotatably sleeved with one end of the lower rotating rod. A connecting ring is fixedly connected to the outer wall of the middle rotating rod. One side inner wall of the tank body is fixedly connected with a water pump, the water inlet end of the water pump is inserted with a water inlet hose, and the water inlet hose is inserted with the connecting ring. A drain pipe is inserted at the bottom of one side of the tank body.

[0007] Further, a protective cover is fixedly connected to the top of the tank body, and the protective cover covers the scissor-type telescopic frame.

[0008] Further, two guide rods are fixedly connected to the bottom of the upper rotating rod.

[0009] Further, a fixing plate is fixedly connected to one side inner wall of the tank body, and the guide rod is slidably inserted into the fixing plate.

[0010] Further, a filter cover is clamped at the other end of the water inlet hose.

[0011] Further, a plurality of hydraulic lifting rods are fixedly connected to the outer wall of the bottom of the tank body, and the bottom ends of the hydraulic lifting rods are fixedly connected with ground wheels.

[0012] Further, a limiting frame is fixedly connected between the inner walls on both sides of the tank body. A floating ball is arranged in the tank body and is located within the limiting frame. A pressure sensor is fixedly connected to the top end of the limiting frame.

Detailed Embodiments

[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0023] Referring to Figures 1 - 4 , a municipal sewage water quality sampling device includes a tank body 1. One side inner wall of the tank body 1 is fixedly connected with an electric push rod 4 through bolts. The top end of the electric push rod 4 is fixedly connected with a scissor-type telescopic frame 3 through bolts. The scissor-type telescopic frame 3 includes an upper rotating rod 301, a lower rotating rod 302 and a plurality of middle rotating rods 303. The upper rotating rod 301 is fixed at the top end of the electric push rod 4. The lower rotating rod 302 is fixed on one side inner wall of the tank body 1. Both ends of the middle rotating rod 303 are rotatably sleeved with a first connecting plate 304 and a second connecting plate 305. One end of the first connecting plate 304 is rotatably connected with one end of the second connecting plate 305. One end of one of the first connecting plates 304 is rotatably sleeved with one end of the upper rotating rod 301. One end of one of the second connecting plates 305 is rotatably sleeved with one end of the lower rotating rod 302. A connecting ring 7 is welded on the outer wall of the middle rotating rod 303. One side inner wall of the tank body 1 is fixedly connected with a water pump 9 through bolts. The water inlet end of the water pump 9 is inserted with a water inlet hose 8. When the electric push rod 4 contracts, it drives the upper rotating rod 301 to move, so that the scissor-type telescopic frame 3 stretches, and then drives the water inlet hose 8 to move. Thus, one end of the water inlet hose 8 extends to the central area of the sewage pool. The water inlet hose 8 is inserted into the connecting ring 7. One side bottom of the tank body 1 is inserted with a drain pipe 12. A valve is provided on the drain pipe 12. When the valve is opened, the sewage in the tank body 1 is discharged from the drain pipe 12.

[0024] A protective cover 2 is fixed to the top of the tank body 1 by bolts. The protective cover 2 covers the scissor-type telescopic frame 3, and the scissor-type telescopic frame 3 is protected by the protective cover 2. Two guide rods 6 are welded to the bottom of the upper rotating rod 301. A fixed plate 5 is welded to the inner wall of one side of the tank body 1. The guide rods 6 are slidably inserted into the fixed plate 5, so as to guide the movement of the upper rotating rod 301 and improve the stability of the adjustment of the scissor-type telescopic frame 3. The other end of the water inlet hose 8 is clamped with a filter cover 10, and the filter cover 10 is used to filter impurities in the sewage. A plurality of hydraulic lifting rods 11 are fixed to the outer wall of the bottom of the tank body 1 by bolts. The bottom end of the hydraulic lifting rod 11 is fixed with a ground wheel 13 by bolts. Driven by the hydraulic lifting rod 11, the tank body 1 moves downward, thereby driving the water inlet hose 8 to move downward, and then putting the water inlet hose 8 into the water. A limiting frame 14 is fixed between the inner walls on both sides of the tank body 1 by bolts. A floating ball 16 is arranged in the tank body 1 and is located in the limiting frame 14. The floating ball 16 is limited by the limiting frame 14. A pressure sensor 15 is fixed to the top end of the limiting frame 14 by bolts. The pressure sensor 15 is electrically connected to the processor and the water pump 9. As the sewage in the tank body 1 increases, the floating ball 16 floats upward. When the floating ball 16 touches the pressure sensor 15, the pressure sensor 15 transmits a pressure signal to the processor, and the processor controls the water pump 9 to stop working.

[0025] Working principle: When in use, after the device is powered on, first, push the sampling device to the vicinity of the sewage pool. Then, control the electric push rod 4 to work. Driven by the contraction of the electric push rod 4, the upper rotating rod 301 moves, so that the scissor-type telescopic frame 3 stretches, and then drives the water inlet hose 8 to move. Thus, one end of the water inlet hose 8 extends to the central area of the sewage pool. Next, control the hydraulic lifting rod 11 to work. Driven by the hydraulic lifting rod 11, the tank body 1 moves downward, thereby driving the water inlet hose 8 to move downward, and then putting the water inlet hose 8 into the water. Then, control the water pump 9 to work. Under the action of the water pump 9, the water in the sewage pool is sucked into the water inlet hose 8 and discharged from the water outlet end of the water pump 9 into the tank body 1. As the sewage in the tank body 1 increases, the floating ball 16 floats upward. When the floating ball 16 touches the pressure sensor 15, the pressure sensor 15 transmits information to the processor. Then, the processor controls the water pump 9 to stop working, so as to realize sampling.
