Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0031] In addition, the term "and / or" in this text is merely a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this text generally represents an "or" relationship between the associated objects before and after.

[0032] As Figures 1 to 8 shown, the present utility model provides a technical solution for a water intake device for detecting the water quality of a drainage pipeline, including: a suction part 1, a water intake part 2, and a water pipe 3. The water pipe 3 is connected between the suction part 1 and the water intake part 2. Through the suction part 1, the water intake part 2 can suck sewage and transfer it to the suction part 1 through the water pipe 3 for storage. In actual use, the water intake part 2 is installed on the inner wall of the sewage well 200. The drainage pipeline 300 is communicated with the sewage well 200. The number of the drainage pipelines 300 is at least two. Sewage enters the sewage well 200 through one drainage pipeline 300 for temporary storage and is output from another drainage pipeline 300. The sewage well 200 serves as a temporary storage device on the sewage discharge path, facilitating the sampling of sewage. At the same time, a cover can be added to the top of the sewage well 200 to improve safety. The position of the bottom of the water intake part 2 is higher than that of the drainage pipeline 300 to prevent the sewage from flooding the water intake part 2. Among them, the sewage well 200 is arranged in the foundation 100. The surface of the foundation 100 is at the same height as the top of the sewage well 200. The suction part 1 is arranged on the surface of the foundation 100.

[0033] The suction part 1 includes a mounting base 11, a pump body 12, a collection tank 13, a mounting hole 14, an exhaust port 15, an outer cover 16 and a through groove 17. The mounting base 11 is installed on the surface of the foundation 100 by expansion bolts. The pump body 12 is installed on the mounting base 11. The pump body 12 is a ZW series self-priming sewage pump, with the model ZW50-20-7.5, which is suitable for sucking urban sewage and can handle sewage containing solid particles or fibrous substances. The mounting hole 14 is opened on the mounting base 11. The water suction port of the pump body 12 is connected to the water pipe 3, and the output end of the pump body 12 is connected to the mounting hole 14. The inner wall of the mounting hole 14 is provided with internal threads, and the collection tank 13 is threadedly connected to the mounting hole 14. A rubber gasket is added at the connection between the collection tank 13 and the mounting hole 14 to ensure airtightness. The collection tank 13 is also provided with an electric valve, which can open or close the passage according to requirements. The exhaust port 15 is installed at the top of the collection tank 13. The exhaust port 15 is used to discharge the gas in the collection tank 13, to prevent sewage from entering the collection tank 13 and the gas from being unable to be discharged, and to prevent the collection tank 13 from bursting. The outer cover 16 is installed at the top of the collection tank 13, and the outer cover 16 is located outside the exhaust port 15. The number of the through grooves 17 is several, and several through grooves 17 are respectively opened on the outer cover 16. There is a gap between the outer cover 16 and the top of the exhaust port 15. The through grooves 17 can ensure the gas flow. By using the outer cover 16 to block the exhaust port 15, sundries can be prevented from falling into the exhaust port and the collection tank 13.

[0034] This solution can ensure the discharge of gas while collecting sewage, ensure the stability of the equipment, and at the same time prevent sundries from falling into the collection tank 13, prevent blockage, and ensure the efficient and stable operation of the equipment.

[0035] The water intake section 2 includes a horizontal plate 21, a connecting seat 22, a first water intake pipe 23, a second water intake pipe 24, a suction pipe 25, an electric push rod 26, a fixing plate 27, a housing 28, a gear 29, a first toothed ring 210, a second toothed ring 211, a third toothed ring 212 and a motor 213. The connecting seat 22 is fixedly connected to the horizontal plate 21. The connecting seat 22 is a hollow cavity. The first water intake pipe 23 is installed between the water pipe 3 and the connecting seat 22, and the first water intake pipe 23 communicates with the inner cavity of the connecting seat 22. The number of the second water intake pipes 24 is three, which are respectively installed on the lower surface of the connecting seat 22, and the second water intake pipes 24 communicate with the inner cavity of the connecting seat 22. The total designed flow rate allowed by the three second water intake pipes 24 is not greater than the designed flow rate of the first water intake pipe 23 and the water pipe 3, so as to avoid excessive suction of sewage leading to blockage of the device or a decrease in efficiency. The suction pipe 25 is connected to the free end of the second water intake pipe 24, and the suction pipe 25 and the second water intake pipe 24 form a closed passage. When the suction pipe 25 sucks sewage, the sewage enters the connecting seat 22 along the second water intake pipe 24, and finally enters the collection tank 13 through the first water intake pipe 23 and the water pipe 3. The second water intake pipe 24 is spiral in shape and is made of elastic rubber, which can be stretched and contracted. When the second water intake pipe 24 is stretched by an external force, it will gradually be straightened, thereby increasing the overall length. After the external force is removed, the second water intake pipe 24 will return to its initial state.

[0036] The electric push rod 26 is installed on the lower surface of the cross plate 21. A suspension plate 216 is installed on the outer wall of the electric push rod 26. The suspension plate 216 is fixed to the inner wall of the sewage well 200 by expansion screws, thereby fixing the electric push rod 26. The fixing plate 27 is installed at the output end of the electric push rod 26. The outer shell 28 is fixedly connected to the fixing plate 27. The gear 29 is rotatably installed in the inner cavity of the outer shell 28. The first tooth ring 210, the second tooth ring 211 and the third tooth ring 212 are respectively rotatably installed in the inner cavity of the outer shell 28, and the first tooth ring 210, the second tooth ring 211 and the third tooth ring 212 are respectively meshed and connected with the gear 29. The inner walls of the first tooth ring 210, the second tooth ring 211 and the third tooth ring 212 are provided with internal threads. The three suction pipes 25 respectively pass through the outer shell 28 and are respectively threadedly connected with the first tooth ring 210, the second tooth ring 211 and the third tooth ring 212. Among them, the threads on the outer walls of the three suction pipes 25 are of the same model as the internal threads on the first tooth ring 210, the second tooth ring 211 and the third tooth ring 212, ensuring that when the first tooth ring 210, the second tooth ring 211 and the third tooth ring 212 rotate one circle, they can drive the suction pipes 25 to lift and lower the same height distance. The circumferences of the first tooth ring 210, the second tooth ring 211 and the third tooth ring 212 increase in sequence, and the ratio of the circumferences of the three is 4:3:2. When the gear 29 rotates, the first tooth ring 210, the second tooth ring 211 and the third tooth ring 212 can respectively rotate different numbers of circles, and then the three suction pipes 25 respectively extend downward by different lengths. For example, when the first tooth ring 210 rotates one circle, it can drive the suction pipe 25 screwed thereto to descend one unit distance. At the same time, the second tooth ring 211 will rotate 4 / 3 circles, and the suction pipe 25 screwed to the second tooth ring 211 will descend 4 / 3 units. At the same time, the third tooth ring 212 rotates 2 circles, and the suction pipe 25 screwed to the third tooth ring 212 will descend 2 units, so that the three suction pipes 25 respectively descend different distances. The motor 213 is installed on the upper surface of the outer shell 28. The output end of the motor 213 penetrates the outer wall of the outer shell 28 and is connected to the gear 29. The motor 213 is selected from the YE3-160M1-2 model in the Y2 series of three-phase asynchronous motors, and this model is applicable to humid environments.

[0037] This solution enables the equipment to operate efficiently and stably in a complex sewage environment, has the ability to simultaneously suck sewage at different depths, ensures that the water sampling covers the entire depth of the sewage, and can also ensure accurate sampling if the sewage precipitates due to standing.

[0038] Three guard plates 214 are also installed on the outer shell 28. The three guard plates 214 are respectively arranged on the upper surface of the outer shell 28, and the positions of the three guard plates 214 correspond to the positions of the three suction pipes 25. The guard plates 214 are used to protect the suction pipes 25, prevent the suction pipes 25 from tilting, and ensure that they always maintain stable vertical movement. At the same time, a chute 217 is provided on the outer wall of the suction pipe 25, and a clamping block 218 is installed on the inner wall of the guard plate 214. The two are slidably matched to ensure that the suction pipe 25 can move up and down stably without self-rotation.

[0039] In addition, two stop pieces 215 are installed on the suction pipe 25 to limit the movement range of the suction pipe 25, prevent the suction pipe from moving excessively and disengaging from the outer shell 28, and ensure the safe and stable operation of the equipment.

[0040] The detailed connection means are well-known techniques in the art. Those skilled in the art connect all the electrical components in this case to their adapted power sources through wires, and should select a suitable controller according to the actual situation to meet the control requirements. For the specific connection and control sequence, reference should be made to the sequence of operations of each electrical component in the following working principle to complete the electrical connection. The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, and no further description of electrical control will be given.

[0041] In actual use, first, the collection tank 13 is screwed to the mounting hole 14, the electric valve on the collection tank 13 is opened, and then the electric push rod 26 is activated to move the outer shell 28 downward to ensure that the bottom ends of the suction pipes 25 correspond to the sewage liquid level. The motor 213 is started to rotate the gear 29, which in turn causes the first toothed ring 210, the second toothed ring 211, and the third toothed ring 212 to rotate synchronously. Since the circumferences of the first toothed ring 210, the second toothed ring 211, and the third toothed ring 212 are different, when the gear 29 rotates a fixed number of turns, the first toothed ring 210, the second toothed ring 211, and the third toothed ring 212 rotate different numbers of turns respectively, and the suction pipes 25 move downward by different lengths, ensuring that the bottom ends of the suction pipes 25 extend into the sewage at different depths. The pump body 12 is started to pump the sewage at different depths through the suction pipes 25, the second water intake pipe 24, the connecting seat 22, the first water intake pipe 23, and the water pipe 3, and finally into the collection tank 13 for storage. Then, the pump body 12 and the electric valve of the collection tank 13 are closed, and the collection tank 13 can be taken away. This equipment can not only quickly and conveniently suck sewage for the detection of the sewage quality in the drainage pipe, but also ensure that the water intake depth covers different levels of the sewage, avoiding inaccurate sampling caused by sewage sedimentation.

[0042] The above specific embodiments do not constitute a limitation on the protection scope of the present utility model. Those skilled in the art should understand that various modifications, combinations, sub - combinations and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
