Description

Technical Field

[0001] The embodiment of the utility model relates to the technical field of sewage sampling and detection, and in particular to an underwater automatic sampler for sewage detection. Background Art

[0002] In sewage treatment research, it is necessary to sample sewage on the surface, and through testing and analysis of the samples, the degree of water pollution, the type and content of pollutants and other related water quality parameters can be determined. A sewage sampler is needed to collect sewage between tests. The sewage sampler adopts a high-reliability peristaltic pump and a hybrid stepper drive to meet the water quality sampling requirements under various environmental conditions. It is suitable for environmental monitoring stations at all levels, sewage treatment plants, water conservancy, water affairs and scientific research institutes, and is an instrument for collecting water samples from industrial sewage outlets, rivers, lakes and seas.

[0003] However, there may be some large garbage in the sewage, which is easy to block the filter screen at the water inlet, resulting in the sewage being blocked outside the filter screen, affecting the sampling of the sewage. Therefore, the prior art publication number is CN218766116U, which is an underwater automatic sampler for surface sewage detection. The utility model uses a permeable groove on the surface of the underwater sampling box for sampling, and uses a motor to drive the cleaning baffle to automatically seal the permeable groove to achieve underwater automatic sampling.

[0004] However, the above-mentioned prior art still has the following problems when used: due to the different pollution levels of sewage in different places, the above-mentioned underwater sampling box can only collect sewage from one place, and it needs to be taken out and cleaned frequently before sewage from other places can be collected. The sampling efficiency is not only low, but also affects the accuracy of detection. Utility Model Content

[0005] To this end, an embodiment of the utility model provides an underwater automatic sampler for sewage detection to solve the problem of inaccurate sewage sampling and detection in the prior art because the sampling box can only collect sewage from one place at a time.

[0006] In order to achieve the above purpose, the embodiment of the utility model provides the following technical solutions:

[0007] An underwater automatic sampler for sewage detection comprises a box body, wherein a partition is fixedly provided inside the box body, wherein the partition divides the inner part of the box body into four spaces, wherein feed ports are provided at the front end and both sides of the box body, wherein each feed port is provided with a sealing assembly for sealing the feed port, wherein grooves are provided at the top and bottom inner walls of the feed port, wherein the sealing assembly comprises a sealing plate, wherein the sealing plate is slidably arranged in the groove and the feed port for sealing the feed port, wherein an electric push rod is fixedly provided on the top of each sealing plate, wherein the electric push rod is an electric drive device for converting the rotational motion of an electric motor into the linear reciprocating motion of a push rod, wherein the electric push rod is embedded in the box body for driving the sealing plate to move up and down, wherein a ring plate is fixedly provided at the rear end of the box body, wherein a propeller is fixedly provided inside the ring plate, wherein a propeller refers to a device for converting the rotational power of an engine into a propulsion force by rotating the propeller blades in the air or water, wherein the propeller may have two or more blades connected to the hub, wherein the rearward side of the blade is a helical surface or a propeller similar to a helical surface, wherein the box body is driven to move underwater by the propeller, and the position of the box body is conveniently adjusted.

[0010] Furthermore, a baffle is hinged at the front end of the box body, and the baffle is fixed to the box body by screws. Opening the baffle makes it convenient for staff to replace the counterweight in the box body.

[0011] Furthermore, a lifting ring is fixedly provided at the center of the top of the box body, a steel wire rope is fixedly provided on the lifting ring, and a winch is fixedly provided on the top of the steel wire rope. Specifically, the winch is a light and small lifting equipment that uses a steel wire rope wound on a drum to lift or pull heavy objects. By using the winch to reel in the steel wire rope, it is convenient for the staff to collect the box body, which is more time-saving and labor-saving to use.

[0012] Furthermore, a lifting ring is fixedly provided at the center of the top of the box body, a steel wire rope is fixedly provided on the lifting ring, and a winch is fixedly provided on the top of the steel wire rope. The winch is used to reel in the steel wire rope, so that the staff can collect the box body conveniently.

[0013] Furthermore, a filter is fixedly provided inside the ring plate, and the filter is arranged in front of the propeller to protect the propeller.

[0014] Furthermore, a controller for controlling the propeller and the electric push rod is fixedly provided inside the box, and a wireless transmission module is fixedly provided on the controller.

[0015] Furthermore, a battery for power supply is provided below the controller, and the battery is fixed on the partition.

[0016] The utility model embodiment has the following advantages:

[0017] 1. The utility model sinks underwater through a counterweight, then uses a propeller to drive the box to move underwater, and then uses an electric push rod to drive the sealing plate to move up into the groove, so that the sewage flows into the space inside the box through the feed port, and then uses the electric push rod to drive the sealing plate to move down to seal the feed port, thereby realizing automatic sampling of sewage, setting three spaces to store sewage, and using a propeller to drive the box to move to different places for collection, thereby improving the detection accuracy of sewage.

[0018] 2. By installing four universal wheels on the top of the box, when the staff takes the box out of the sewage, they can turn the box over and use the four universal wheels to support the movement of the box. It is very convenient to carry. After removing the bottom plate, the inside of the box can be cleaned, and the wire rope can be reeled in with a winch, and fixed with the wire rope and the lifting ring on the box to prevent the box from being lost.
