Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, and in particular to a sampling device for wastewater treatment. Background Technology

[0002] A wastewater sampling device is a piece of equipment used to extract water samples from the wastewater treatment process. Its main purpose is to collect and test parameters such as wastewater composition, pollutant concentration, pH value, and temperature to monitor and analyze wastewater quality. This helps to understand the operating status of the wastewater treatment system, ensure that the treatment effect meets environmental protection requirements, and promptly identify and address any problems.

[0003] For example, a Chinese patent publication with patent number CN220829376U proposes a sampling device for the detection of thiocyanate wastewater after treatment. The device uses a gate-shaped frame to ensure the stability of the overall structure. The adjusting plate slides up and down within the frame to sample wastewater that does not pass through a certain depth. Two sets of symmetrically arranged lifting devices can stably and quickly drive the adjusting plate to slide up and down, thereby driving the sampling container to collect wastewater samples.

[0004] While the aforementioned cited patent achieves sampling of wastewater at different depths, it still has certain limitations. Specifically, the wastewater sampling described in the document can only be performed at a single point, making it difficult to perform range-based sampling at different points within the same depth. Because single-point sampling focuses on only one specific point, it cannot comprehensively reflect the overall water quality of the wastewater or sewage body. The composition and pollutant concentration of wastewater may vary at different points, especially in large water treatment tanks, sedimentation tanks, or complex piping systems. Single-point sampling ignores lateral differences in the water body, resulting in poor representativeness of water quality data and an inability to fully understand the pollution level of the water body at different locations. Furthermore, multiple sampling at the same depth involves a complex process, requiring multiple relocations of the sampling device.

[0005] Therefore, considering the efficiency of a single sampling, a sampling device for wastewater treatment is proposed to solve the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a sampling device for wastewater treatment, which can effectively cover multiple different points of the wastewater body, eliminate the limitations of single-point sampling, and simultaneously perform sampling at different depths.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0010] The height adjusting assembly comprises a vertical frame arranged on the upper end face of the bottom plate, a rectangular groove is formed in the side face of the vertical frame, and a screw rod nut is slidably arranged in the rectangular groove.

[0011] The limiting assembly comprises a clamping seat arranged on the lower end face of the screw rod slider, the clamping seat is arranged in a U-shaped structure, and notches are formed in the two side walls of the clamping seat.

[0012] Further, the clamping seat forms a U-shaped cavity, and the limiting assembly is arranged in the clamping seat and between the two push blocks.

[0013] Further, the limiting assembly further comprises two light rods arranged on the two sides of the clamping seat, the two light rods arranged on the same side form a group, and the end portions of the two light rods are supported by a side plate, push rod motors are arranged on the two side plates, and the end portions of the two push rod motors extend through the side plate and are connected with the end portions of the push blocks.

[0014] Further, the bottom of the two side walls of the clamping seat is integrally provided with a U-shaped baffle, and the two U-shaped baffles are oppositely arranged and clamp the wastewater sampler body.

[0015] Further, the height adjusting assembly further comprises a threaded screw rod rotating in the vertical frame, a screw rod nut is threadedly engaged with the outer portion of the threaded screw rod, and the screw rod nut penetrates the sliding shaft sleeve and is connected with the sliding shaft sleeve.

[0016] Further, a forward and reverse motor is arranged on the top end of the vertical frame, and the output end of the forward and reverse motor is connected with the top end of the threaded screw rod.

[0017] In summary, the utility model has the following beneficial effects:

[0018] 1. By controlling the movement of the linear screw rod module, sampling can be performed at different transverse positions of the water body, such as different regions of the pool and different pipeline positions.

[0046] Specific implementation process:

[0047] First step: in actual use, when the user needs to sample and detect the treated wastewater, first assemble the wastewater sampler body 6 on the two sets of limiting assemblies 5, place the top end of the wastewater sampler body 6 in the clamping seat 51, then connect the two sets of push rod motors 54 to the external power supply, then drive the output end of the push rod motor 54, so that the two push rod motors 54 can push the push block 55. The user controls the push stroke of the push rod motor 54, so as to realize the clamping action of the two push blocks 55 on the wastewater sampler body 6. The user can install the two sets of wastewater sampler bodies 6 by using the above method;

[0048] Second step: when the two sets of wastewater sampler bodies 6 are assembled on the two sets of limiting assemblies 5, the user adjusts the distance between the two sets of wastewater sampler bodies 6 according to the requirements. During this period, the two sets of linear lead screw modules 4 are driven respectively, so that the linear lead screw module 4 can adjust the sliding position of the lead screw block 41.

This design can effectively cover multiple different points of the wastewater water body and eliminate the limitations of single-point sampling;

[0049] Third step: when the user needs to sample wastewater at different depths, the forward and reverse motor 25 is connected to the power supply, at this time the set forward and reverse motor 25 will drive the threaded lead screw 22 to rotate, when the threaded lead screw 22 rotates, the sliding shaft sleeve 24 is limited by the vertical frame 21, so that the screw nut 23 engaged outside the threaded lead screw 22 can drive the sliding shaft sleeve 24 to move vertically along the travel range of the threaded lead screw 22, when the sliding shaft sleeve 24 moves, the lifting platform 3 installed on the side of the sliding shaft sleeve 24 can drive the linear lead screw module 4, the limiting assembly 5 and the wastewater sampler body 6 to move synchronously, during this period, through the movement of the height adjusting assembly 2, the wastewater sampler body 6 can realize different levels of sampling of wastewater in the vertical direction, ensuring that samples of different depths from the water surface to the bottom of the water are obtained, ensuring the consistency of the data.
