Description

Technical Field

[0001] This utility model relates to supporting equipment for sewage treatment, and in particular to a water intake device for sewage discharge outlets. Background Technology

[0002] Wastewater treatment is a crucial aspect of environmental protection. Existing wastewater treatment processes mainly include physical, chemical, and biological methods. Physical treatment primarily removes suspended solids and particulate matter from wastewater through sedimentation and filtration; chemical treatment utilizes chemical agents to react with harmful substances in wastewater to remove pollutants; and biological treatment uses the metabolic processes of microorganisms to convert organic matter in wastewater into harmless substances.

[0003] Wastewater often needs to be sampled before treatment. The usual practice is to sample manually or using sampling equipment. Manual sampling is time-consuming, labor-intensive, and has very low sampling efficiency. Sampling equipment mostly uses pumps to pump wastewater into sampling bottles. Although pumping is simple and fast, the residual wastewater in the pump can cause cross-contamination of the wastewater in subsequent samples after multiple samplings, affecting the accuracy of the sample. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides a wastewater discharge outlet water intake device.

[0005] The technical solution of this utility model to achieve the above objectives is a wastewater discharge outlet water intake device, comprising:

[0006] A water tank is provided with a support pipe on one side, a base at the lower end of the support pipe, and the base is fixedly installed on the ground. A water tank cover is provided on one side surface, and a water inlet is provided on one side of the lower surface.

[0007] A bent sampling tube is inserted into the water inlet and fixedly connected to the water tank. Its upper end is connected to the support tube. A limiting top plate is installed above it and is located inside the water tank. An electric winch mechanism is installed on the limiting top plate.

[0008] The sampling seat is set on one side of the curved sampling tube and connected to the wire rope of the electric winch mechanism. A positioning ring is set on one side of the sampling seat, which is fitted onto the curved sampling tube. An elastic clamp is installed on the other side of the sampling seat, and a lifting seat is movably embedded on the upper side of the other side. An elastic clamp is also installed on one side of the lifting seat.

[0009] A stepping rotary lifting sampling bottle mechanism is installed inside the water tank and corresponds to the position of the water tank lid. It includes:

[0010] A stepper motor is installed on the lower surface of the water tank. A rotating shaft is installed on its rotating end, which is located inside the water tank. A short splined shaft is installed on the rotating shaft.

[0011] A rotating sleeve is fitted onto a rotating shaft and slidably connected to a short spline shaft. Several telescopic rods are provided on its outer surface and are evenly distributed. Tension springs are fitted on the telescopic rods. A sampling bottle holder is installed at the telescopic end of the telescopic rod. A sampling bottle groove is opened at the center of the upper surface of the sampling bottle holder.

[0012] The lifting electric push rod is installed on the upper surface inside the water tank, with its telescopic end facing downwards and connected to the upper end of the rotating sleeve through a bearing;

[0013] A horizontal electric push rod is installed inside the water tank and located on one side below the limiting top plate, between the rotating sleeve and one of the sampling bottle seats. It is connected to the telescopic end of the lifting electric push rod through a bracket.

[0014] The sampling bottle is slidably inserted into the sampling bottle slot, and two clamp limiting rings are provided on its outer surface.

[0015] The sampling bottle stopper is pressed tightly against the mouth of the sampling bottle, and two clamping limit rings are also set on the upper part of its outer surface.

[0016] In this invention, a sliding rod is installed at the lower end of the lifting seat. The sliding rod is slidably inserted into the sampling seat, and the lifting seat can be raised from the sampling seat by the elastic force of the compression spring.

[0017] In this invention, when the lifting seat is embedded in the sampling seat, the elastic force of the compression spring is greater than the force required to open the sampling bottle stopper.

[0018] In this invention, after the lifting electric push rod is fully retracted, the rotating sleeve rises to a certain height and aligns the sampling bottle and the sampling bottle stopper with the elastic clamps on the sampling seat and the lifting seat, respectively.

[0019] In this invention, after the lifting electric push rod is fully retracted, the horizontal electric push rod pushes the sampling bottle seat to move, so that the sampling bottle and the sampling bottle stopper respectively open the elastic clamp and are inserted into it, while the elastic clamp is located between the two clamp limiting rings.

[0020] In this invention, the curved sampling tube is located directly above the sewage discharge outlet, and its lower end is located inside the sewage.

[0021] In this invention, the elastic clamp has an outer elastic metal plate and an inner rubber pad.

[0022] In this invention, the sampling bottle is made of stainless steel on the outside and glass on the inside.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] 1. The electric winch mechanism controls the lifting and lowering of the sampling seat on the curved sampling tube. In conjunction with the stepping rotary lifting sampling bottle mechanism, wastewater is sampled in a timed and quantitative manner. On the one hand, this reduces the workload of staff and improves sampling efficiency. On the other hand, it ensures the accuracy and reliability of wastewater sampling and avoids cross-contamination of samples.

[0025] 2. By utilizing the sampling seat and lifting seat, and through their cooperation with the limiting top plate, the sampling bottle can be automatically opened by the spring force to sample the sewage. On the other hand, the limiting top plate can be used to squeeze the sampling bottle stopper back into the sampling bottle to store the sewage, ensuring the smooth sampling and storage of sewage.

[0037] 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.

[0038] This utility model provides a technical solution, such as Figures 1-6 As shown; a wastewater discharge outlet water sampling device includes: a water sampling tank 1, a support pipe 11 installed on one side, a base 12 installed at the lower end of the support pipe 11, the base 12 being fixedly installed on the ground, a water sampling tank cover 13 provided on one side surface, and a water intake port 14 opened on one side of its lower surface; the support pipe 11 allows the water sampling tank 1 to be suspended above the wastewater discharge outlet, thereby facilitating wastewater sampling; the water sampling tank cover 13 allows staff to quickly replace the sampling bottle 45 so that the device can perform timed and quantitative sampling of wastewater again; and the water intake port 14 facilitates the raising and lowering of the sampling seat 3, allowing the sampling bottle 45 to descend into the wastewater for sampling, and after sampling, it can be returned to the water sampling tank 1.

[0039] In this utility model, although the water tank cover 13 is located on one side of the water tank 1, it may cause some inconvenience to the staff when changing the sampling bottle 45. Therefore, the water tank cover 13 can be set facing the sewage discharge outlet, so as to facilitate the staff to change the sampling bottle 45.

[0040] A curved sampling tube 2 is inserted into the water inlet 14 and fixedly connected to the water tank 1. Its upper end is connected to the support tube 11. A limiting top plate 21 is installed above it and located inside the water tank 1. An electric winch mechanism 22 is installed on the limiting top plate 21. A sampling seat 3 is set on one side of the curved sampling tube 2 and connected to the wire rope of the electric winch mechanism 22. A positioning ring 31 is set on one side of the sampling tube 2. The positioning ring 31 is fitted onto the curved sampling tube 2. An elastic clamp 32 is installed on the other side of the sampling tube 2. A lifting seat 33 is movably embedded on the upper side of the other side of the sampling tube 2. An elastic clamp 32 is also installed on one side of the lifting seat 33.

[0041] In this embodiment of the invention, the connection between the curved sampling tube 2 and the support tube 1 can characterize the stability of the installation of the curved sampling tube 2, thereby ensuring the smoothness of sewage sampling. Furthermore, by bending the lower end of the curved sampling tube 2 in the direction of sewage flow, the sampling seat 3 can descend along the curved sampling tube 2, allowing the sampling bottle 45 to be tilted and submerged in the sewage. This ensures rapid sewage sampling and also prevents the sampling bottle 45 from being filled with sewage, facilitating the smooth insertion of the sampling bottle stopper 46 into the sampling bottle 45.

[0042] In this embodiment of the invention, the sampling bottle 45 and the sampling bottle stopper 46 are clamped by the elastic clamps 32 on the sampling bottle holder 3 and the lifting seat 33. Then, the elasticity of the compression spring is used to make the lifting seat 33 drive the sampling bottle stopper 46 to open. Then, the electric winch mechanism 22 is used to control the sampling seat 3 to lift and lower, so that the sampling bottle 45 can quickly sample the sewage. Finally, the limiting top plate 21 is used to squeeze the lifting seat 33, so that the sampling bottle stopper 46 can be inserted back into the sampling bottle 45 to ensure the sealed storage of the sample, so that the device can automatically sample and ensure the sample accuracy.

[0043] A stepper rotary lifting sampling bottle mechanism 4 is installed inside the water tank 1 and corresponds to the position of the water tank cover 13. It includes: a stepper motor 41, mounted on the lower surface of the water tank 1, with a rotating shaft 411 mounted on its rotating end, the rotating end of which is located inside the water tank 1; a short splined shaft 412 mounted on the rotating shaft 411; a rotating sleeve 42, fitted onto the rotating shaft 411 and slidably connected to the short splined shaft 412; several telescopic rods 421 evenly distributed on its outer surface; tension springs 422 mounted on the telescopic rods 421; and sampling bottle holders 423 mounted on the telescopic ends of the telescopic rods 421. A sampling bottle groove 42 is formed at the center of the upper surface of the sampling bottle holder 423. 4; The lifting electric push rod 43 is installed on the upper surface inside the water tank 1, with its telescopic end facing downwards, and is connected to the upper end of the rotating sleeve 42 through a bearing; The horizontal electric push rod 44 is installed inside the water tank 1, located on one side below the limiting top plate 21, and between the rotating sleeve 42 and one of the sampling bottle seats 423, and is connected to the telescopic end of the lifting electric push rod 43 through a bracket 441; The sampling bottle 45 is slidably inserted into the sampling bottle slot 424, and two clamp limiting rings 451 are provided on its outer surface; The sampling bottle stopper 46 is pressed against the bottle mouth of the sampling bottle 45, and two clamp limiting rings 451 are also provided on its outer surface.

[0044] In this embodiment of the invention, the stepper motor 41 drives the rotating sleeve 42 to move the sampling bottle holder 423 one by one to the horizontal electric push rod 44. Then, the horizontal electric push rod 44 and the lifting electric push rod 43 work together to allow the sampling bottle 45 and the sampling bottle stopper 46 to be respectively locked into the elastic clamp 32 for wastewater sampling. After sampling, the sampling bottle 45 can be inserted into the sampling bottle holder 423, and the contraction separates the sampling bottle 45 from the sampling bottle stopper 46 and the feces from the elastic clamp 32, thus facilitating the storage of the sampling bottle 45.

[0045] In this embodiment of the utility model, the short spline shaft 412 is used to ensure the stability of the power transmission between the rotating sleeve 42 and the rotating shaft 411 when the lifting electric push rod 43 drives the rotating sleeve 42 to rise and fall, thereby ensuring the smooth rotation of the rotating sleeve 42.

[0046] In this embodiment of the utility model, the transverse electric push rod 44 is installed on the telescopic end of the lifting electric push rod 43 through the bracket 441. On the one hand, the transverse electric push rod 44 can be raised and lowered synchronously with the rotating sleeve 42, so as to facilitate the sampling bottle 45 to be inserted into or removed from the elastic clamp 32. On the other hand, it can avoid affecting the rotation adjustment of the sampling bottle seat 423, so that the sampling bottle 45 can be sampled one by one for sewage sampling.

[0047] In this embodiment of the utility model, the telescopic end of the lifting electric push rod 43 is connected to the rotating sleeve 42 through a bearing, which ensures the smooth rotation of the rotating sleeve 42 and can drive the rotating sleeve 42 to lift and lower, thereby facilitating the removal and retraction of the sampling bottle 45.

[0048] In this invention, a sliding rod 331 is installed at the lower end of the lifting seat 33. The sliding rod 331 is slidably inserted into the sampling seat 3, and the lifting seat 33 can be raised from the sampling seat by the elastic force of the compression spring. After the sampling bottle 45 and the sampling bottle stopper 46 are snapped into the lifting seat 33 and the sampling bottle seat 3 on one side, the sampling bottle stopper 46 can be automatically pulled out from the sampling bottle 45 by pressing the compression spring, so as to sample the sewage.

[0049] In this invention, when the lifting seat 33 is embedded in the sampling seat 3, the elastic force of the compression spring is greater than the force required to open the sampling bottle stopper 46; ensuring that the sampling bottle stopper 46 can be quickly pulled out using the elasticity of the compression spring.

[0050] In this invention, after the lifting electric push rod 43 is fully retracted, the rotating sleeve 42 rises to a certain height, aligning the sampling bottle 45 and the sampling bottle stopper 46 with the elastic clamps 32 on the sampling seat 3 and the lifting seat 33, respectively. After the lifting electric push rod 43 is fully retracted, the transverse electric push rod 44 pushes the sampling bottle seat 423 to move, causing the sampling bottle 45 and the sampling bottle stopper 46 to open the elastic clamps 32 and insert into them, while the elastic clamps 32 are located between the two clamp limiting rings 451. This ensures that the sampling bottle stopper 46 and the sampling bottle 45 can be smoothly clamped onto one side of the lifting seat 33 and the sampling seat 3, so that the sampling bottle stopper 46 can be pulled out and the sampling bottle 45 can sample the sewage.

[0051] In this invention, the curved sampling tube 2 is located directly above the sewage discharge outlet, and its lower end is inside the sewage; this allows the sampling bottle 45 to descend into the sewage, thereby enabling it to successfully sample the sewage.

[0052] In this invention, the elastic clamp 32 has an outer elastic metal plate and an inner rubber pad. The elasticity of the elastic metal plate and the rubber pad allows the sampling bottle 45 and the sampling bottle stopper 46 to open the elastic clamp 32 and be inserted into it, while also facilitating separation from the elastic clamp 32.

[0053] In this invention, the sampling bottle 45 is made of stainless steel on the outside and glass on the inside, which improves the lifespan of the sampling bottle 45 and ensures the accuracy of the sample.

[0054] In specific use of this utility model, after the sampling bottle 45 is inserted into the sampling slot 424 through the water tank cover 13, the stepper motor 41 is controlled to work for multiple cycles to adjust the sampling bottle 45 numbered 01 to the telescopic end of the horizontal electric push rod 44.

[0055] When it is necessary to sample the sewage, the lifting electric push rod 43 is controlled to retract, which drives the rotating sleeve 42 to rise, thereby causing the sampling bottle holder 423 to drag the sampling bottle 45 to rise and move the sampling bottle 45 to one side of the sampling seat 3. After the lifting electric push rod 43 is fully retracted, the horizontal electric push rod 44 is controlled to extend, which pushes the sampling bottle holder 423 to move and makes the sampling bottle 45 and the sampling bottle plug 46 approach the sampling seat 3 and the lifting seat 33 respectively. Then, the sampling bottle 45 and the sampling bottle plug 46 are used to open the elastic clamps 32 respectively, so that the sampling bottle 46 and the sampling bottle plug 46 are clamped in the two elastic clamps 32 respectively, while the elastic clamps 32 are located between the two clamp limiting rings 451.

[0056] Subsequently, the lifting electric push rod 43 is fully extended, which pushes the rotating sleeve 42 down and separates the sampling bottle holder 423 from the sampling bottle 45. Then, the horizontal electric push rod 44 is retracted, so that the sampling bottle holder 423 automatically resets using the elasticity of the tension spring 422 and is removed from under the sampling bottle 45.

[0057] Then, the electric winch mechanism 22 can be controlled to start working, so that it releases the wire rope and uses the weight of the sampling seat 3 to drive the sampling bottle 45 to start descending. During the descent, as the lifting seat 33 separates from the limiting top plate 21, the elasticity of the compression spring allows the lifting seat 33 to pull the sampling bottle plug 46 out of the bottle mouth of the sampling bottle 45 through the cooperation of the elastic clamp 32 and the clamp limiting ring 451, thus putting the sampling bottle 45 in the open state. Then, through the descent of the sampling seat 3 along the curved sampling tube 2, the sampling bottle 45 gradually descends into the sewage, and the bending of the curved sampling tube 2 itself causes the sampling bottle 45 to tilt at a certain angle.

[0058] Wait for a certain period of time to allow the sampling bottle 45 to sink into the sewage, so that the sewage is stored in the sampling bottle 45. Then, control the electric winch mechanism 22 to start winding the wire rope, thereby dragging the sampling seat 3 to start rising. During the rising process, use the tilt of the sampling bottle 45 to discharge excess sewage. Then, use the rising of the sampling seat 3 along the curved sampling tube 2 and through the water intake port 14 to bring the sampling seat 3 back into the water intake tank 1.

[0059] When the sampling seat 3 contacts the limiting top plate 21, the electric winch mechanism 22 is stopped. During this process, the lifting seat 33 contacts the limiting top plate 21 first, so that the lifting seat 33 is squeezed back into the sampling seat 3. The elastic clamp 32 drives the sampling bottle stopper 46 to descend, so that the sampling bottle stopper 46 is inserted into the sampling bottle 45, thereby sealing the sampling bottle 45.

[0060] At this time, the horizontal electric push rod 44 is extended to push the sampling bottle holder 423 to move below the sampling bottle and align the sampling bottle 45 with the sampling bottle slot 424. Then, the lifting electric push rod 43 is retracted to drive the sampling bottle holder 423 to rise and insert the sampling bottle 45 into the sampling bottle holder 423.

[0061] Finally, control the retraction of the horizontal electric push rod 44, and then use the elastic force of the tension spring 422 to drive the sampling bottle holder 423 to reset. Then, use the driving force of the sampling bottle holder 423 to move the sampling bottle 45 and the sampling bottle stopper 46 out of the elastic clamp 32. After that, control the extension of the lifting electric push rod 43 to reset the device.

[0062] When sampling is required again, the staff controls the stepper motor 41 to work for one cycle, so that the next sampling bottle 45 moves to the telescopic end of the horizontal electric telescopic rod 44, and then sampling can be carried out in the same way as described above.
