DETAILED DESCRIPTION
[0030] The following is a brief description of the implementation of the present utility model in conjunction with the accompanying drawings.
[0031] A wastewater sampling device, referring to 1- Figure 2 , including a support 1, an extension structure 2, and a moving mechanism 3. The bottom of the support 1 is provided with a moving wheel 11, so as to facilitate the movement of the wastewater sampling device at the edge of the wastewater tank. The extension structure 2 is fixedly installed on the upper part of the support 1 and extends outside the support 1. The extension structure 2 includes a crossbeam 21. Figure 3-Figure 6 A rotatable steering wheel 22 is provided at the front end of the beam 21, and a first rope-pulling driving wheel 23, a second rope-pulling driving wheel 27 and a rope-lifting driving wheel 24 are installed on a mounting seat 214 and a mounting plate 215 at the rear end of the beam 21. The first rope-pulling driving wheel 23, the second rope-pulling driving wheel 27 and the rope-lifting driving wheel 24 can all rotate relative to the beam 21, and a slide groove 213 is provided between the front end and the rear end of the beam 21, and the moving mechanism 3 is slidably arranged between the two ends of the slide groove 213.
[0032] Reference Figure 7 , Figure 8 , Fig. 9The moving mechanism 3 includes a moving seat 31, a first pull rope 33 and a second pull rope 34 connected at both ends of the moving seat 31, and a first lifting rope 36 penetrating the interior of the moving seat 31. A sliding portion 311 corresponding to the slide groove 213 is provided at the bottom of the moving seat 31. A rotatable second pulley 35 is installed on the side wall of the sliding portion 311. The second pulley 35 slides against the side wall of the slide groove 213. Through the sliding connection between the second pulley 35 and the slide groove 213, the moving seat 31 can better slide between the two ends on the slide groove 213. Usually, the shape of the sliding portion 311 is set to an inverted convex structure, and correspondingly, the slide groove 213 is set to an inverted convex groove. The sliding portion 311 and the slide groove 213 are slidably matched through the inverted convex shape, thereby ensuring the stable sliding of the moving seat 31 on the slide groove 213.
[0033] The front end of the movable seat 31 is provided with a head 312 protruding from the sliding portion 311. The head 312 is provided with an inner groove 313. Two sets of opposite and rotatable first pulleys 32 are provided in the inner groove 313. There is a gap between the first pulleys 32. The first lifting rope 36 passes through the gap between the first pulleys 32 and turns vertically from the lifting rope driving wheel 24 to the bottom of the movable seat 31.
[0034] Among them, one end of the first pull rope 33 of the moving mechanism 3 is connected to the front end of the moving seat 31 and is turned and wound around the first pull rope driving wheel 23 via the steering wheel 22. In order to ensure the sliding balance of the first pull rope 33 on the moving seat 31, two first pull ropes 33 are provided, and the first pull ropes 33 are respectively arranged on both sides of the slide groove 213. After the first pull rope 33 is turned by the steering wheel 22, it passes through the side hole 316 passing through the moving seat 31 and is wound around the first pull rope driving wheel 23. One end of the second pull rope 34 is connected to the rear end of the moving seat 31 and is wound around the second pull rope driving wheel 27. The first pull rope driving wheel 23 is coaxially provided with a rotating member 26. Specifically, the rotating member 26 is a rotating handle 261. The rotating handle 261 is used to conveniently control the first pull rope driving wheel 23 rotates, by rotating the first pull rope driving wheel 23, the first pull rope driving wheel 23 is wound around the first pull rope 33, and the first pull rope 33 makes the movable seat 31 slide toward the front end of the beam 21 through the steering wheel 22, that is, the movable seat 31 moves away from the support 1. Of course, in order to ensure that the movable seat 31 does not slide out of the slide groove 213, a limiting plate 211 is provided at the front end of the beam 21, and a guide hole 212 is provided on the limiting plate 211 for the first pull rope 33 to pass through. The limiting plate 211 can better realize the sliding limit of the movable seat 31 and prevent the movable seat 31 from directly abutting against the steering wheel 22. The guide hole 212 can better realize the guidance of the first pull rope 33 and prevent the first pull rope 33 from falling off during the process of tightening or loosening.
[0035] The second rope-pull driving wheel 27 can be rotated. By rotating the second rope-pull driving wheel 27, the second rope-pull driving wheel 27 is wound around the second rope 34, and the second rope 34 slides the moving seat 31 toward the rear end of the crossbeam 21, that is, the moving seat 31 moves closer to the support 1. There is no coaxial rotating member 26 on the second rope-pull driving wheel 27. The rotation of the second rope-pull driving wheel 27 is achieved by rotating the rotating handle 261 coaxially connected to the first rope-pull driving wheel 23 through the meshing transmission of the gear 25. The first rope-pull driving wheel 23 and the second rope-pull driving wheel 27 are coaxially connected with the gear 25, and the gear 25 on the first rope-pull driving wheel 23 is meshed with the gear 25 on the second rope-pull driving wheel 27. In this way, only by rotating the rotating handle 261, the first rope-pull driving wheel 23 and the second rope-pull driving wheel 27 can be synchronously rotated in the opposite direction, thereby ensuring the synchronous movement of the first pull-up driving wheel 23 and the second rope-pull driving wheel 27 with the first rope 33 and the second rope 34. Specifically, rotating the first When the rope driving wheel 23 causes the first rope driving wheel 23 to wind the first rope 33, the second rope driving wheel 27 realizes a counter-rotation through the meshing gear 25, and correspondingly, the second rope driving wheel 27 rotates in the opposite direction, so that during the rotation of the second rope driving wheel 27, the second rope driving wheel 27 correspondingly loosens the second rope 34 to release the line, and then, when the first rope 33 is tightened and the second rope 34 is loosened and released, the movable seat 31 moves toward the front end direction of the beam 21; conversely, when the first rope driving wheel 23 is rotated to cause the first rope driving wheel 23 to loosen the first rope 33, the second rope driving wheel 27 realizes a counter-rotation through the meshing gear 25, so that during the rotation of the second rope driving wheel 27, the second rope driving wheel 27 correspondingly tightens the second rope 34 to reel in the line, and then, when the first rope 33 is loosened and the second rope 34 is tightened and reeled in, the movable seat 31 moves toward the rear end direction of the beam 21.
[0036] In the present embodiment, it should be noted that since the first pull rope 33 needs to be steered by the steering wheel 22 to realize the movement control of the moving seat 31, therefore, after the first pull rope 33 is steered, when controlling the moving seat 31 to move the same distance, the required length of the first pull rope 33 is twice the length of the second pull rope 34. Therefore, in the present embodiment, in order to ensure the synchronization of the first pull rope 33 and the second pull rope 34 during the movement of the moving seat 31, the diameter of the first pull rope driving wheel 23 is set to twice the diameter of the second pull rope driving wheel 27, and the gears 25 connected to the first pull rope driving wheel 23 and the second pull rope driving wheel 27 are gears 25 of the same size. In this way, during the rotation of the first pull rope driving wheel 23, the length of the first pull rope 33 wound or released is twice the length of the second pull rope 34 wound or released by the second pull rope driving wheel 27.
[0037] In this embodiment, the moving mechanism 3 is provided with a first lifting rope 36 and two second lifting ropes 37 arranged on both sides of the first lifting rope 36. One end of the first lifting rope 36 and the second lifting rope 37 are wound around the lifting rope driving wheel 24, and the other ends of the first lifting rope 36 and the second lifting rope 37 are vertically turned to the bottom of the moving seat 31 via the first pulley 32 on the moving seat 31. The side wall of the head 312 of the moving seat 31 is provided with a lifting rope hole 315, and the first lifting rope 36 and the second lifting rope 37 are horizontally guided through the lifting rope hole 315 and wound around the lifting rope driving wheel 24.
[0038] The end of the first lifting rope 36 is connected to the collection bottle 4, the second lifting rope 37 is connected to the upper sealing structure 41 of the collection bottle 4, and the lifting rope driving wheel 24 is coaxially provided with a rotating member 26. Specifically, the rotating member 26 is a turntable 262. The turntable 262 is used to conveniently control the lifting rope driving wheel 24. The lifting rope driving wheel 24 loosens the first lifting rope 36, so that the collection bottle 4 drops into the wastewater pool below the moving seat 31 to collect wastewater.
[0039] Collection bottle 4, reference Fig.11 , refer to the patent application of the applicant previously entitled "A bottom-inlet liquid collection device" (application number CN2024206813743), the collection bottle 4 includes a cylindrical tank body, an upper sealing structure 41, and a lower sealing structure. A lifting rod is provided on the upper part of the tank body, and a lifting rod column is provided in the middle of the lifting rod. The interior of the lifting rod column is hollow, and a first lifting rope 36 is provided on the lifting rod column. The upper sealing structure 41 is rotatably arranged and is connected to a second lifting rope 37. The second lifting rope 37 can control the opening or closing of the upper sealing structure 41. The second lifting rope 37 is used to control the opening of the upper sealing structure 41, so that the internal pressure of the tank body is reduced, so that the pressure of the liquid at the bottom of the tank body squeezes the lower sealing structure, so that the lower sealing structure opens the liquid inlet, thereby realizing the sampling process of the tank body.
[0040] In this embodiment, a guide tube 314 corresponding to the gap between the first pulleys 32 is provided at the bottom of the sliding portion 311, so that the first lifting rope 36 and the second lifting rope 37 are vertically guided by the guide tube 314, thereby preventing the collection bottle 4 from shaking during the rising or falling process.
[0041] In this embodiment, refer to Fig.10 The first pulley 32 is provided with a first groove 321 corresponding to the first lifting rope 36 and a second groove 322 corresponding to the second lifting rope 37 . The first groove 321 and the second groove 322 can better realize the sliding positioning of the first lifting rope 36 and the second lifting rope 37 .
[0042] The above embodiments only express the implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
