Description

Technical Field

[0001] This utility model belongs to the field of water quality testing technology, and in particular relates to a water quality testing sampling device. Background Technology

[0002] In fields such as environmental protection, water conservancy projects, drinking water safety supervision, and industrial wastewater discharge monitoring, water quality testing is a crucial step in assessing the degree of water pollution, determining the health status of the ecological environment, and protecting human health. Scientific and accurate water sampling is the prerequisite for ensuring the reliability of water quality testing results. As society increasingly emphasizes water environmental quality, various water quality testing scenarios place higher demands on the practicality, stability, and adaptability of sampling devices. However, current water quality testing sampling devices on the market still have many technical shortcomings, making it difficult to meet the sampling needs of complex application scenarios.

[0003] Existing methods for water quality sampling in lakes mostly involve directly pumping water from the lake. However, water pumped directly through the pump pipes contains a large number of impurities, and the extracted samples need to be filtered twice before they can be tested, which is very inconvenient. In view of this, we propose a water quality testing and sampling device. Utility Model Content

[0004] The purpose of this invention is to provide a water quality testing and sampling device to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a water quality testing and sampling device, comprising:

[0006] A water pump and a filter cover are provided. The water pump is equipped with a water pump pipe and a water drain pipe. A top cover is fixedly installed on the outer wall of the water pump pipe. The top cover is movably connected to the filter cover. One end of the water pump pipe is set inside the filter cover.

[0007] Two side blocks are fixedly installed on both sides of the top cover. An outer ring is fixedly installed on the outer side wall of the filter cover. Two positioning blocks are fixedly installed on the top surface of the outer ring. Positioning grooves are opened on the top surface of the two side blocks. The two positioning blocks are movably connected to the two positioning grooves respectively.

[0008] Two movable seats are slidably mounted on the top surface of the top cover. Limiting rods are fixedly installed on the opposite sides of the two movable seats. One end of each limiting rod is movably sleeved in one of the two positioning blocks.

[0009] A movable component, which is disposed on the top cover and is used to move two movable seats;

[0010] A rotating rod is rotatably mounted on the bottom surface of the filter cover. A support plate is fixedly mounted on the outer wall of the rotating rod. An annular groove is formed on the bottom surface of the outer ring, and an arc-shaped moving plate is slidably mounted in the annular groove. The bottom surface of the arc-shaped moving plate is fixedly connected to the top surface of the support plate. A cleaning scraper and a cleaning brush are provided on one side of the arc-shaped moving plate. The cleaning scraper and cleaning brush are in contact with the surface of the filter cover. When the filter cover is damaged and needs to be replaced, the first limiting bolt is rotated. When the first limiting bolt rises and no longer contacts the surface of the lead screw, the limiting of the lead screw is released. At this time, rotating the adjusting block drives the lead screw to rotate. When the lead screw rotates, it drives the moving plate to move through the threaded sleeve. When the moving plate moves closer to the adjusting block, the two moving seats move together through the cooperation of the two adjusting rods, bringing the two moving seats closer. When the two moving seats move to a certain position, the two limiting rods will disengage from the two positioning blocks. At this time, the limiting between the top cover and the filter cover is released, and the water pipe can be separated from the top cover for replacement with a new filter cover.

[0011] In the above technical solution, the movable component further includes a movable plate, which is slidably mounted on the top surface of the top cover. Adjusting rods are rotatably mounted on both sides of the movable plate that are far apart from each other. The other ends of the two adjusting rods are rotatably mounted in two movable seats respectively. When the movable plate moves towards the adjusting block, the two movable seats will move together through the cooperation of the two adjusting rods, so that the two movable seats are close together. When the two movable seats move to a certain position, the two limiting rods will disengage from the two positioning blocks. At this time, the limiting between the top cover and the filter cover is released, and the water pipe can be separated from the top cover for replacement with a new filter cover.

[0012] In the above technical solution, the moving component further includes a top groove, which is formed on the top surface of the top cover. A lead screw is rotatably installed in the top groove, and a threaded sleeve is threadedly connected to the lead screw. The top end of the threaded sleeve is fixedly connected to the bottom surface of the moving plate. When the lead screw rotates, it will drive the moving plate to move through the threaded sleeve.

[0013] In the above technical solution, an adjusting block is rotatably installed on one side of the top cover. One end of the adjusting block is fixedly connected to one end of the lead screw, and the lead screw can be easily rotated by rotating the adjusting block.

[0014] In the above technical solution, the top surface of the top cover is further threaded with a first limiting bolt. The bottom end of the first limiting bolt abuts against the outer wall of the lead screw. When the first limiting bolt contacts the lead screw, it will limit the lead screw to prevent the lead screw from rotating, which would cause the limiting structure between the top cover and the filter cover to loosen, resulting in the top cover and the filter cover separating.

[0015] In the above technical solution, a second limiting bolt is further threaded onto the support plate. The top of the second limiting bolt contacts the bottom surface of the filter cover. When the second limiting bolt contacts the bottom surface of the filter cover, it will limit the support plate, thereby limiting the cleaning scraper and cleaning brush.

[0016] In the above technical solution, the cleaning scraper and the cleaning brush are both bolted to one side of the arc-shaped moving plate. When the cleaning scraper and the cleaning brush are worn or damaged, they can be disassembled and replaced.

[0017] The beneficial effects of this utility model are:

[0018] 1. When the surface of the filter cover is clogged and needs cleaning, the second limiting bolt is rotated to move the top of the second limiting bolt away from the filter cover. When the second limiting bolt is no longer in contact with the bottom surface of the filter cover, the limiting of the rotating rod is released. At this time, the rotating rod is rotated. When the rotating rod rotates, it will drive the arc-shaped moving plate to rotate through the cooperation of the support plate. The arc-shaped moving plate will move in a ring around the surface of the filter cover. Then, the surface of the filter cover is cleaned by the cleaning scraper and the cleaning brush.

[0019] 2. When the filter cover of this water quality testing and sampling device is damaged and needs to be replaced, the first limit bolt is rotated. When the first limit bolt rises and no longer contacts the surface of the lead screw, the limit on the lead screw is released. At this time, rotating the adjusting block drives the lead screw to rotate. When the lead screw rotates, it drives the moving plate to move through the threaded sleeve. When the moving plate moves closer to the adjusting block, it drives the two moving seats to move through the cooperation of the two adjusting rods, so that the two moving seats are close together. When the two moving seats move to a certain position, the two limit rods will disengage from the two positioning blocks. At this time, the limit between the top cover and the filter cover is released, and the water pump pipe can be separated from the top cover for replacement with a new filter cover.
