Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, specifically to a device for detecting heavy metal content in aquaculture areas. Background Technology

[0002] In aquaculture, especially in ecological fish farming, regular testing of the aquaculture environment is necessary to ensure the health of fish and the quality and safety of fish products. This mainly includes testing of the aquaculture water and bottom sediment. Heavy metal content testing is an important part of this testing. However, laboratory testing for heavy metal content in bottom sediment is costly and time-consuming. To monitor the aquaculture environment in real time, portable X-ray fluorescence spectrometers are now widely used. These instruments can directly perform on-site preliminary screening of bottom sediment samples, which is faster and facilitates timely monitoring of the aquaculture environment.

[0003] However, in the actual use of portable X-ray fluorescence spectrometers, the moisture in the sediment and the pores on the sample surface will scatter the X-ray signal, affecting the detection accuracy. The current detection equipment lacks a pretreatment structure for compacting and dewatering the sediment sample, which is not conducive to detection.

[0004] Based on this, this utility model designs a heavy metal content detection device for aquaculture areas to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, this utility model provides a device for detecting heavy metal content in aquaculture areas.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A heavy metal content detection device for aquaculture areas includes a base frame and a portable X-ray fluorescence spectrometer. The portable X-ray fluorescence spectrometer includes control keys, a display screen, and a probe. A slot is provided at the top of the base frame, and the portable X-ray fluorescence spectrometer is mounted in the slot. A pretreatment component is installed at the probe end of the portable X-ray fluorescence spectrometer. The pretreatment component includes an outer frame, an inner frame, a side plate, a side sliding groove, a side slider, a moving plate, an adjusting screw, and a pressure plate. The outer frame is fixed to the end of the portable X-ray fluorescence spectrometer, and the inner frame is installed inside the outer frame. The inner frame includes a rigid plate and a water-absorbing layer. The side plate is fixed to the outside of the outer frame. The side sliding groove is provided on the side of the side plate, and the side slider slides in the side sliding groove. The moving plate is fixed on the side slider, and the adjusting screw is threaded through the moving plate and its end is rotatably connected to the pressure plate.

[0008] Furthermore, the probe on the portable X-ray fluorescence spectrometer extends beyond the edge of the bottom frame, the top and bottom of the inner frame are level with the top and bottom of the outer frame cavity, the top of the movable plate is higher than the top of the side plate, and the top and bottom of the pressure plate are level with the top and bottom of the inner frame cavity.

[0009] Furthermore, the top of the outer frame and the top of the portable X-ray fluorescence spectrometer are provided with a connection hole, and a connecting bolt is fixed in the thread of the connection hole.

[0010] Furthermore, a mounting plate is fixed to the bottom of the side plate, and a mounting bolt is threaded between the mounting plate and the bottom of the outer frame. The mounting bolt does not penetrate the outer frame.

[0011] Furthermore, the side sliding groove is provided through one side of the side plate, the movable plate is threadedly fixed on the side sliding groove, and a leakage hole is provided on one side of the outer frame.

[0012] Furthermore, a bottom sliding groove is provided at the center of the bottom end of the inner cavity of the outer frame. The bottom sliding groove extends through one side of the outer frame, and a bottom sliding block slides inside the bottom sliding groove. The inner frame is threadedly fixed to the bottom sliding block.

[0013] Furthermore, a lower through groove is provided at the center of the top of the inner frame, and an upper through groove is provided at the top of the outer frame directly opposite the lower through groove.

[0014] Furthermore, the bottom groove is provided with equally spaced perforated grooves, which extend through the bottom end of the outer frame.

[0015] Beneficial effects

[0016] 1. By setting up pretreatment components, the extracted bottom mud samples can be pretreated before testing. By adjusting the screw to drive the pressure plate, the sample is squeezed and spread out. With the cooperation of the water-absorbing layer, the moisture in the bottom mud sample is pretreated, and the gas is squeezed out to eliminate pores, thereby improving the accuracy of on-site testing and making it easier for testing personnel to grasp the quality of fishpond bottom mud.

[0017] 2. The design incorporates connecting holes and bolts, facilitating the assembly and disassembly of the outer frame. The mounting plate and bolts further simplify the assembly and disassembly of pretreatment components. A through-type side sliding groove facilitates the assembly and disassembly of the side slider, moving plate, adjusting screw, and pressure plate. Drainage holes and channels, combined with the pressure plate's contact with the sample, compress it, pre-treating the moisture in the sediment sample and aiding drainage. A bottom sliding groove and bottom slider allow for adjustment of the inner frame's position after pretreatment, bringing it closer to the probe for easier detection. Lower and upper through-slots and baffles allow for sample placement from above, protecting the operator's hands from contact with the probe when the equipment is running.
