Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices, in particular to a portable sampler. Background Art

[0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants and their changing trends, and evaluating the water quality status. Water quality is the status of evaluating the quality of water bodies, and a series of water quality parameters and water quality standards are specified.

[0003] Some devices on the market generally lower the water quality sampler to a specified depth in the water body, and use the driving component to drive the end cover to move upward to open the water inlet. The water sample can then pass through the water permeable hole into the sampling bottle, thereby realizing the water sample collection process. After the water sample is collected, the driving component is controlled to stop driving the end cover, and the end cover moves downward under the action of the return member to block the water inlet, thereby realizing the complete water sample collection process.

[0004] However, during the actual use of the above-mentioned device, after the sample bottle enters the water, the water will contain a lot of debris, which will block the water inlet when the water enters the sample bottle through the water inlet hole, making it impossible for the device to sample the water well; in view of this, we propose a portable sampler. Utility Model Content

[0005] The purpose of the utility model is to provide a portable sampler to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a portable sampler, comprising a mounting plate, a handle is fixedly connected to the upper surface of the mounting plate, an electric telescopic rod is fixedly connected to the bottom of the mounting plate, a fixing plate is fixedly connected to the bottom of the electric telescopic rod, a limiting plate is fixedly connected to the outer surface of the electric telescopic rod, a through hole is provided on the upper surface of the limiting plate, a mounting groove is provided on the upper surface of the fixing plate, a sample bottle is clamped inside the mounting groove, a bottle cap is provided on the top of the sample bottle, a filter is provided on the upper surface of the bottle cap, a cleaning device is provided on the top of the mounting plate, and the cleaning device includes:

[0007] A motor is arranged at the center of the upper surface of the mounting plate, a sealing cover is fixedly connected to the bottom of the mounting plate, a baffle is fixedly connected to the output end of the motor, and the baffle is arranged in a cross shape;

[0008] A slide groove is provided on the upper surface of the sample bottle, a slide rod is clamped inside the slide groove, one end of the slide rod is fixedly connected to a fixed block, the interior of the fixed block is hollow, and the fixed block is made of rubber material.

[0009] Preferably, the position of the fixing block corresponds to the position of the filter screen, and the size of the fixing block matches the size of the filter screen, so that the fixing block can block the filter screen well.

[0010] Preferably, the size of the baffle plate is matched with the size of the filter screen, and the position of the baffle plate corresponds to the position of the filter screen, so that the baffle plate can block the upper surface of the filter screen.

[0011] Preferably, the position of the sealing cover corresponds to the position of the bottle cap, and the size of the sealing cover matches the size of the bottle cap, so that the sealing cover can cover the bottle cap.

[0012] Preferably, a limiting block is fixedly connected to the outer surface of the sample bottle, a slot is provided on one side of the limiting block, one end of a connecting rod is clamped inside the slot, and the other end of the connecting rod is hinged to the bottom of the limiting plate.

[0013] Preferably, the size of the connecting rod is matched with the size of the card slot, the number of the connecting rods is two, and the two connecting rods are symmetrically arranged at the center of the sample bottle.

[0014] Compared with the prior art, the utility model provides a portable sampler with the following beneficial effects:

[0015] 1. The portable sampler is used to prevent debris from blocking the water inlet when the equipment is sampling. The handle is fixed with a rope, and then the equipment is put into water. The motor is started to rotate the baffle and intersect with the filter screen set on the upper surface of the bottle cap, so that the water can enter the sample bottle after being filtered by the filter screen for larger debris. A fixed block is set inside the sample bottle, and the fixed block is hollow and made of rubber. As the water enters the sample bottle, the water pushes the fixed block to rise and block the filter screen, so that the water in the sample bottle cannot leak out. When larger debris blocks the filter screen, the motor is started to rotate the baffle, which can cause the baffle to form a water flow stirring on the upper surface of the filter screen, thereby cleaning the debris on the surface of the filter screen and allowing the equipment to take samples better.

[0016] 2. In order to make the sample bottle more sealed, the electric telescopic rod of the portable sampler is extended to make the fixed plate drive the sample bottle down, so that one end of the connecting rod hinged at the bottom of the limit plate can slowly slide out from the slot opened on one side of the limit block. At this time, the connecting rod releases the limit on the sample bottle, and at the same time, the electric telescopic rod contracts to make the fixed plate rise, so that the bottle cap set on the top of the sample bottle is just stuck in the sealing cover, so that the sample bottle can be well sealed and the water inside the sample bottle is not easy to flow out.
