[0034] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0035] Please refer to Figure 1-Figure 4 This embodiment provides a sewage sample collection device 100, which includes a mounting frame 110, a liquid guiding component 130, and a sampling component 150; the mounting frame 110 is movably connected to the wall of the sewage tank 200.

[0036] The liquid guiding assembly 130 includes a liquid extraction frame 131, a driving component 132, a movable component 133, a liquid extraction tube 134, and a liquid guiding tube 135. The liquid extraction frame 131 is connected to the mounting frame 110, the driving component 132 is connected to the liquid extraction frame 131, and the driving component 132 is drivenly connected to the movable component 133, which is vertically movably connected to the liquid extraction frame 131. The liquid extraction tube 134 is connected to the movable component 133, so that it can move vertically relative to the liquid extraction frame 131 under the driving action of the driving component 132, so as to adjust the depth of the liquid extraction tube 134 immersed in the sewage tank 200. The liquid guiding tube 135 communicates with the liquid extraction tube 134 and with the sampling assembly 150.

[0037] The sampling assembly 150 includes a sampling water pump 151 and a sampling box 152. The sampling water pump 151 is connected to the liquid guide pipe 135 and the sampling box 152 to guide the water drawn by the liquid extraction pipe 134 into the sampling box 152 for sampling.

[0038] Please refer to Figure 1-Figure 4 The working principle of the wastewater sample collection device 100 is as follows:

[0039] The wastewater sample collection device 100 includes a mounting frame 110, a liquid guiding component 130, and a sampling component 150;

[0040] The mounting frame 110 is movably connected to the wall of the sewage tank 200. This arrangement allows the mounting frame 110 to move along the wall of the sewage tank, thereby adjusting its position relative to the sewage tank 200 and facilitating sampling at different locations. It should be noted that this arrangement allows the position of the mounting frame 110 to remain unchanged within a certain period and to complete multiple samplings continuously within that period.

[0041] The function of the liquid guiding component 130 is to extract water at a preset depth in the sewage tank 200 according to the sampling requirements and transport it to the sampling component 150 to achieve sampling; specifically, the liquid guiding component 130 includes a liquid extraction frame 131, a driving component 132, a moving component 133, a liquid extraction pipe 134, and a liquid guiding pipe 135.

[0042] Furthermore, during the sampling process, the driving component 132 can be controlled according to the sampling requirements, thereby causing the movable component 133 to move vertically relative to the sampling frame 131. In this way, the position of the sampling pipe 134 connected to the sampling frame 131 can be adjusted, thereby adjusting the depth of the sampling pipe 134 immersed in the sewage tank 200. It should be noted that within the same cycle, with the position of the mounting frame 110 unchanged, water samples at different depths in the sewage tank 200 can be collected by adjusting the vertical position of the sampling pipe 134 to meet the testing requirements. Moreover, during this process, the sampling pipe 134 can be adjusted to complete water sampling work at different depths.

[0043] The liquid guide tube 135 is connected to the liquid extraction tube 134 and the sampling component 150. The sampling water pump 151 is connected to the liquid guide tube 135 and the sampling box 152. This allows the liquid extraction tube 134 to draw water from one end of its extension into the sewage tank 200 into the liquid extraction tube 134 under the action of the sampling water pump 151. The water then flows into the sampling box 152 through the liquid guide tube 135, making it easier for staff to take samples based on the water in the sampling box 152.

[0044] This setup allows sampling to be carried out outside the sewage tank 200, and staff do not need to stand on the wall of the sewage tank 200 to operate, thereby improving the safety of the sampling operation.

[0045] In summary, the wastewater sample collection device 100 can improve sampling efficiency, adapt to different sampling frequencies, and its sampling method is simple and convenient, which can reduce the labor intensity and sampling risks of staff.

[0046] Further, please refer to Figure 1-Figure 4In this embodiment, the sampling component 150 further includes a rectifier tube 153, the two ends of which are connected to the sampling box 152 and the liquid guide tube 135, respectively; wherein, a multi-way valve 154 is provided at the connection between the rectifier tube 153 and the liquid guide tube 135. This configuration allows the rectifier pipe 153 to be connected to or disconnected from the liquid guide pipe 135. During use, by positioning the sampling box 152 below the end of the suction pipe 134 within the sewage tank 200, the siphon principle can be utilized to allow water from the sewage tank 200 to flow into the sampling box 152 when the corresponding pipes in the suction pipe 134, liquid guide pipe 135, rectifier pipe 153, and sampling box 152 are connected and emptied. Specifically, before emptying the rectifier pipe 153, the multi-way valve 154 is used to connect the sampling pump 151 to the sampling box 152, thus drawing water from the sewage tank 200 into the sampling box 152. Then, once the liquid level in the sampling box 152 is above the end of the rectifier pipe 153 and the pipe connecting to the sampling pump 151, the multi-way valve 154 is used to connect the rectifier pipe 153 to the sampling box 152. 3. The sampling pump 151 is connected to the sampling box 152. The sampling pump 151 then pumps water out of the sampling box 152 through the rectifier pipe 153 and pumps it back into the sampling box 152 to empty the rectifier pipe 153, that is, to fill the rectifier pipe 153 with water. Then, by controlling the multi-way valve 154, the rectifier pipe 153 is connected to the guide pipe. Thus, when the pipe is filled with water, the water in the sewage tank 200 can be introduced into the sampling box 152 through the suction pipe 134, the guide pipe and the rectifier pipe 153 when the sampling pump 151 is stopped, thereby reducing the operating energy consumption. It should be noted that this setting can be adjusted according to the usage requirements. When the sampling frequency is low, the sampling pump 151 can be used to pump water for sampling. When the sampling frequency is high and a continuous water output is required, the aforementioned siphon water output method can be used to reduce energy consumption.

[0047] Further, please refer to Figure 1-Figure 4 To prevent blockage of the suction pipe 134 during the pumping process, a filter head 136 is connected to the end of the suction pipe 134 that is submerged below the liquid surface of the sewage tank 200. Based on the above, the suction pipe 134 is detachably connected to the movable part 133 to facilitate adjustment of its length or maintenance.

[0048] Please refer to Figure 1-Figure 4In this embodiment, as described above, since the moving part 133 can be moved by the driving part 132, thereby adjusting the depth of the suction pipe 134 extending into the sewage tank 200, in order to maintain the communication between the guide pipe 135 and the suction pipe 134 after the position of the suction pipe 134 changes, the guide pipe 135 includes a first segment 137 and a second segment 138. The first segment 137 is connected to the second segment 138, and the first segment 137 is connected to the suction pipe 134, while the second segment 138 is connected to the sampling pump 151. The first segment 137 is a corrugated telescopic pipe. That is, by setting the first segment 137 to a telescopic structure, it can adapt to the positional changes of the suction pipe 134 during its movement, thereby maintaining its communication.

[0049] It should also be noted that, please refer to Figure 1-Figure 4 In this embodiment, the purpose of configuring the driving component 132 and the movable component 133 is to adjust the position of the liquid extraction tube 134 vertically. This can be achieved by using existing technologies such as linear motor modules and linear lead screw movable structures. The specific structural settings are the same as those in the prior art, so they will not be described in detail here.

[0050] To facilitate the movement of the mounting frame 110 relative to the wall of the sewage tank 200, rollers 111 are provided on the contact surfaces of the mounting frame 110 with the wall of the sewage tank 200.

[0051] Further, please refer to Figure 1-Figure 4 In this embodiment, during the water sampling process, there is residual water. In order to return the residual water to the sewage tank 200, the sewage sample collection device 100 also includes a water return component 170. The water return component 170 is connected to the sampling box 152 and is used to guide the water in the sampling box 152 into the sewage tank 200.

[0052] For details, please refer to Figure 1-Figure 4 The water return assembly 170 includes a water return tank 171, a water return pipe 172, and a water return pump 173. The water return tank 171 is connected to the sampling box 152, and the water return tank 171 is connected to the sewage tank 200 through the water return pipe 172. The water return pump 173 is connected to the water return pipe 172.

[0053] That is, the residual water in the sampling box 152 is returned to the return water tank 171, and then pumped back to the sewage tank 200 through the return water pump 173 via the return water pipe 172.

[0054] When connecting the sampling box 152 to the return water tank 171, an overflow pipe 139 can be installed on the sampling box 152. The overflow pipe 139 is located at the overflow port of the sampling box 152 and is connected to the return water tank 171 through the overflow pipe 139, thereby allowing the overflow water to be guided into the return water tank 171. In addition, to improve the efficiency of water return and the emptying efficiency of the sampling box 152, a vent and a vent plate movably installed at the bottom of the sampling box 152 can also be installed. The return water tank 171 is located directly below the vent and is used to receive the water discharged when the vent is open. It should be noted that the aforementioned overflow pipe 139 and vent can be installed individually or simultaneously.

[0055] To facilitate cleaning and maintenance, both the sampling box 152 and the return water tank 171 are detachably connected to the mounting frame 110.

[0056] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
