Description

Technical Field

[0001] The utility model relates to the technical field of sewage drug detection, in particular to a water sampler for sewage detection. Background Art

[0002] Human life is inseparable from water. The quality of domestic drinking water is closely related to human health. With the development of social economy, scientific progress and the improvement of people's living standards, people's requirements for the quality of domestic water are constantly increasing, and the water quality standards are also constantly developing and improving accordingly. Water quality detection is also widely concerned in many occasions, especially the detection and analysis of trace drugs in sewage. There will be some drug residues in the existing domestic sewage discharged into the sewage by drug addicts through the sewer or entering the sewage through human excreta. These sewage pollute the environment and damage the ecological balance. Therefore, it is necessary to treat the sewage containing drugs. When treating sewage, it is necessary to detect the sewage to check the drug content in the water and whether there are drug components in the sewage. Before sewage detection, a water sampler will be used for sampling.

[0003] The patent document with the publication number of CN219178992U discloses a sewage detection sampling device, including a sampling bottle; a threaded bottle mouth is fixedly installed at the bottom end of the sampling bottle, an installation seat is arranged below the sampling bottle, a threaded interface is opened at the upper end of the installation seat, the threaded interface is threadedly connected with the threaded bottle mouth, a base is fixedly installed at the bottom end of the installation seat, a counterweight block is arranged inside the installation seat, a driving component is arranged inside the base, a water inlet component is fixedly installed at the bottom end of the base, and a suspension rope is arranged at the upper end of the sampling bottle; the sewage detection sampling device drives the counterweight block through the driving component, and drives water into the sampling bottle through the counterweight block, so as to realize the sampling process at a specified position for the sewage detection sampling device. However, the existing technology still has defects:

[0004] (1) The sampling structure of the sampling device in the existing technology is imperfect. When in use, only one sewage sample can be collected at a time. Only after the collected sample is taken out can the next group be collected. When sampling sewage at different depths, multiple operations are required, reducing the working efficiency of sewage drug detection.

[0005] (2) The sampling device in the existing technology lacks a good anti-blocking structure. If there are too many solid impurities in the sewage, it is easy to cause the phenomenon of blockage in the water inlet tank, which may affect the water intake work of the sewage, and thus affect the accuracy of the drug detection results in the sewage. Content of the Utility Model

[0006] The technical problem to be solved by the utility model is to overcome the above defects and provide a water sampler for sewage detection.

[0007] To solve the above technical problems, the technical solution provided by the present utility model is as follows: A water sampler for sewage detection, comprising:

[0008] A housing, with a top cover provided at the top of the housing;

The rotating shaft extends to the top of the top cover and the end is fixedly connected with a scraper. An inlet hole is opened on one side of the top cover. A filter screen is fixedly installed at the top of the inner wall of the inlet hole.

[0012] A sealing baffle, which is provided at the top of the inner wall of the housing.

[0013] Further, external thread one is provided on the top of the outer wall of the housing, and internal thread one is provided on the inner wall of the top cover. The top cover is threadedly connected with the external thread one of the housing through the internal thread one.

[0014] Further, an installation groove is opened at the bottom of the water intake cylinder, and internal thread two is provided on the inner wall of the installation groove.

The water intake cylinder drives the sealing baffle to rotate synchronously, enabling one of the multiple water intake cylinders to communicate with the external sewage through the water inlet hole on the top cover. In this way, during collection, the sewage can only be filled into one water intake cylinder at a time. Whenever a group of sewage is collected, the motor one drives the installation disk to rotate intermittently to switch the water intake cylinder, thereby improving the load-bearing capacity of the water intake device, being able to load various different sewage samples, and thus sampling sewage at different depths and positions through one water intake operation, improving the work efficiency of sewage drug detection.

[0019] (2) In this utility model, through the anti-blocking structure, the sewage enters the inner cavity of the water intake cylinder through the water inlet hole. Through the setting of the filter screen, the sewage can be filtered to prevent large-volume solid debris from entering the inner cavity of the water intake cylinder. By starting the motor two, the rotating shaft drives the scraper to rotate, scraping off the debris on the surface of the filter screen, effectively preventing blockage during the water intake process, avoiding affecting the drug detection results of the sewage, and improving the efficiency of subsequent sewage drug detection.

When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in 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 making creative efforts shall fall within the protection scope of the present utility model.

[0028] As Figures 1 to 5 shown, this embodiment provides a water sampler for sewage detection, including a housing 1. A top cover 2 is provided at the top of the housing 1. An external thread one is provided at the top of the outer wall of the housing 1. An internal thread one is provided on the inner wall of the top cover 2. The top cover 2 is threadedly connected to the external thread one of the housing 1 through the internal thread one, facilitating the installation and disassembly between the housing 1 and the top cover 2.

[0029] An installation structure 3 is provided at the bottom inside the housing 1. A water intake cylinder 4 is provided at the top of the installation structure 3. The installation structure 3 includes a motor one 31 fixedly installed at the bottom of the inner wall of the housing 1. The output end of the motor one 31 is fixedly connected to an installation disk 32. An annular groove 33 is opened at the lower end of the inner wall of the housing 1. The installation disk 32 is rotatably connected inside the annular groove 33. Among them, a rubber sealing ring is provided on the inner wall of the annular groove 33. A plurality of positioning columns 34 distributed in a circular pattern are fixedly connected to the top of the installation disk 32. An external thread two is provided on the outer wall of the positioning column 34. An installation groove 41 is opened at the bottom of the water intake cylinder 4. An internal thread two is provided on the inner wall of the installation groove 41. The water intake cylinder 4 is threadedly connected to the external thread two on the outer wall of the positioning column 34 through the internal thread two. By threadedly connecting the positioning column 34 and the installation groove 41, it is convenient to separate the water intake cylinder 4 from the housing 1, so as to take out the obtained sewage water sample for subsequent detection of drugs in the sewage.

[0030] The top cover 2 is provided with an anti-blocking structure 5. The anti-blocking structure 5 includes a fixed column 51 fixedly connected to the middle of the bottom of the top cover 2. A second motor 52 is fixedly installed inside the fixed column 51. The output end of the second motor 52 is fixedly connected to a rotating shaft, and the rotating shaft extends to the top of the top cover 2 and is fixedly connected to a scraper 53 at the end. An inlet hole 54 is opened on one side of the top cover 2. A filter screen 55 is fixedly installed at the top of the inner wall of the inlet hole 54. The inlet hole 54 is communicated with the water intake cylinder 4, so that sewage enters the inner cavity of the water intake cylinder 4 for storage. Through the arrangement of the filter screen 55, the sewage can be filtered, and large-volume solid debris can be prevented from entering the inner cavity of the water intake cylinder 4. By starting the second motor 52, the rotating shaft drives the scraper 53 to rotate, and the debris on the surface of the filter screen 55 is scraped off, effectively preventing blockage during the water intake process and avoiding affecting the drug detection result of the sewage.

[0031] It should be noted here that the connection between the rotating shaft on the second motor 52 and the top of the top cover 2 is made by using a sealing bearing with good sealing performance available on the market. The sealing bearing here can be selected from, including but not limited to, deep groove ball bearings, outer spherical bearings, stainless steel bearings and other bearings with sealing performance as a bearing. Since the above bearings are all prior arts, their technical principles will not be elaborated here.

[0032] A sealing baffle 6 is provided at the top of the inner wall of the outer shell 1. A clamping groove 61 is opened on the top of the inner wall of the outer shell 1 for cooperating with the sealing baffle 6. A rubber sealing ring is provided on the outer wall of the sealing baffle 6. A through hole 62 for cooperating with the fixed column 51 is opened in the middle of the top of the sealing baffle 6. A plurality of through holes 63 for cooperating with the water intake cylinder 4 are opened on the top of the sealing baffle 6. The sealing baffle 6 is used to open and close the inlet hole 54. The arrangement of the through hole 62 facilitates the removal of the sealing baffle 6, thus facilitating water treatment. When the first motor 31 drives the mounting plate 32 to rotate intermittently, the water intake cylinder 4 can drive the sealing baffle 6 to rotate synchronously in the clamping groove 61, and then drive the inlet hole 54 to be intermittently communicated with the water intake cylinder 4. One of the plurality of water intake cylinders 4 can be communicated with the external sewage through the inlet hole 54 on the top cover 2. In this way, when collecting, the sewage can only be filled into one water intake cylinder 4 at a time, so that the sewage at different depths and positions can be sampled through one water intake operation during water intake, which is convenient for subsequent drug detection of the sewage.

[0033] Lifting tools 7 are fixedly connected to the upper ends of both sides of the outer shell 1. Through the arrangement of the lifting tools 7, it is convenient to select a suitable rope to connect with them according to the depth of the sewage to be detected, so that the outer shell 1 can be lowered into the sewage for water intake work.

[0034] When the present utility model is specifically implemented, during use, first select a rope with a corresponding length according to the depth of the sewage to be sampled, install it on the outer wall of the lifting device 7, and place the housing 1 into the sewage. When the housing 1 reaches the specified depth, then start the first motor 31 to drive the mounting plate 32 to rotate intermittently, thereby driving the water intake cylinder 4 and the sealing baffle 6 to rotate synchronously, so that one of the plurality of water intake cylinders 4 is communicated with the external sewage through the water inlet hole 54 on the top cover 2, enabling the sewage to enter the inner cavity of the water intake cylinder 4 for storage. In this way, when collecting, only the sewage can be filled into one water intake cylinder 4 at a time. The filter screen 55 filters the sewage to prevent large-volume solid debris from entering the inner cavity of the water intake cylinder 4. At the same time, start the second motor 52 to drive the scraper 53 to rotate, scraping off the debris on the surface of the filter screen 55, effectively preventing blockage during the water intake process. Whenever a group of sewage is collected, the first motor 31 can be used to drive the mounting plate 32 to rotate intermittently to switch the water intake cylinder 4, thereby improving the load-bearing capacity of the water intake device and enabling it to load various different sewage samples. After the water intake is completed, take out the housing 1 from the sewage, rotate the top cover 2, remove the top cover 2, and then rotate the water intake cylinder 4 to disengage the installation groove 41 from the positioning column 34 to take out the water intake cylinder 4. Then take out the sewage in the water intake cylinder 4, improving the efficiency of subsequent sewage drug detection.
