Description

Technical Field

[0001] This utility model relates to the field of tolerance testing technology, and more specifically, to a device for testing the tolerance of largemouth bass to sulfate stress. Background Technology

[0002] In aquaculture environmental stress research, sulfate stress tolerance testing of largemouth bass is a crucial step in assessing their survival adaptability and environmental resilience. However, practical experiments have revealed that most existing testing devices can only be set up at a single test site, making it impossible to conduct multiple parallel experiments simultaneously, resulting in extremely low efficiency. Furthermore, different test groups are easily affected by environmental factors such as temperature fluctuations and uneven water quality. For example, within the same batch of experiments, some groups may have higher water temperatures, while others may have unstable sulfate concentrations, leading to significant deviations in experimental results and poor data repeatability. This not only prolongs the experimental cycle but also fails to meet the research requirements for efficient and accurate test results. In addition, the structural design of existing devices is not flexible enough, making parameter adjustments and observation during testing inconvenient and causing considerable operational difficulties. Therefore, there is an urgent need for a sophisticated testing device specifically designed to address these issues. Utility Model Content

The temperature sensor is embedded in the lower part of the side wall of each of the independent test chambers, and the sensor detection end is encapsulated in stainless steel.

[0011] In a preferred embodiment of this utility model, the locking assembly includes a U-shaped plate and insert rods. The U-shaped plate is symmetrically and slidably installed on the top outer side of the test chamber. Multiple insert rods are fixedly installed on the inner wall of the U-shaped plate.

[0028] Example 3

[0029] Please see Figures 1-7 This utility model provides a technical solution: a largemouth bass sulfate stress tolerance testing device, including a test chamber 110. The inner wall of the test chamber 110 is provided with a plurality of first U-shaped grooves 111. A first U-shaped frame 112 is inserted into the first U-shaped groove 111. A partition 120 is inserted into the inner wall of the first U-shaped frame 112. A locking component that cooperates with the first U-shaped frame 112 and the partition 120 is installed on the outer side of the test chamber 110. The test chamber 110 is divided into a plurality of independent test chambers by the partition 120. Each independent test chamber is provided with a water inlet pipe 130 at the top and a drain pipe 113 at the bottom. A water quality control module is installed on the water inlet pipe 130. A temperature conduction pipe 114 is installed on one side of the inner wall of the independent test chamber. One end of the temperature conduction pipe 114 passes through the test chamber 110 and is fixedly installed with a temperature control module.

[0030] In some specific implementations, the locking assembly includes a U-shaped plate 140 and insert rods 141. The U-shaped plate 140 is symmetrically slidably mounted on the top outer side of the test chamber 110. Multiple insert rods 141 are fixedly mounted on the inner wall of the U-shaped plate 140. The bottom end of each insert rod 141 passes through the outer side of the test chamber 110 and the first U-shaped frame 112, and is inserted into the partition 120. An adjustment assembly is installed at one end of the U-shaped plate 140. The first U-shaped frame 112 has round holes that match the insert rods 141. Round grooves matching the insert rods 141 are provided on both sides of the partition 120 to prevent displacement of the partition 120 due to water flow or fish collisions during testing, ensuring the structural integrity of each independent test chamber and avoiding experimental interference caused by chamber communication. The adjustment assembly includes a side plate 150, a bidirectional threaded rod 151, and an L-shaped plate 152. Side plates 150 are symmetrically fixedly installed on both sides of the test chamber 110. A bidirectional threaded rod 151 and a guide rod 153 are rotatably installed between the two side plates 150 on each side. L-shaped plates 152 are symmetrically fixedly installed at both ends of the U-shaped plate 140. The two L-shaped plates 152 on each side are symmetrically threaded onto the bidirectional threaded rod 151 and slidably installed onto the guide rod 153. A rotating shaft is fixedly installed at one end of the bidirectional threaded rod 151, and the other end of the rotating shaft passes through the side plate 150 and is fixedly installed on the turntable 154. The bidirectional threaded rod 151 and the guide rod 153 are symmetrically arranged on both sides of the test chamber 110, which enables the quick insertion or removal of the insertion rod 141. The operation is convenient and efficient, and the locking, fixing, disassembly and adjustment of the partition 120 can be completed quickly, adapting to the flexible adjustment requirements of the number of independent test chambers under different test scenarios.

[0031] In some specific implementations, a dustproof plate 155 is fixedly installed between the two side plates 150 on one side. The dustproof plate 155 is arc-shaped, and an L-shaped plate 152 is slidably installed on the dustproof plate 155. The bidirectional threaded rod 151 is located directly below the dustproof plate 155, which can effectively prevent dust and debris from contaminating the bidirectional threaded rod 151 and avoid affecting its rotation accuracy and service life.

[0032] Working principle: The test chamber 110 is connected to the first U-shaped frame 112 through the first U-shaped groove 111 on the inner wall. Then, the second U-shaped groove on the inner wall of the first U-shaped frame 112, together with the U-shaped sealing strip 121, is connected to the partition 120, dividing the test chamber 110 into multiple independent test chambers. Rotating the turntable 154 of the adjustment component drives the bidirectional threaded rod 151 to rotate, causing the L-shaped plate 152 to slide along the guide rod 153. This drives the insertion rod 141 on the U-shaped plate 140 to pass through the test chamber 110 and the first U-shaped frame 112 and insert into the circular groove of the partition 120, achieving a stable locking of the partition 120. The heat insulation pad inside the partition 120 and the U-shaped sealing strip 121 together ensure the sealing and heat insulation effect of each independent test chamber. During testing, the main pipe 132 is fixed to the top of the test chamber 110 through the inclined vertical plate 131. External water is diverted to each water inlet pipe 130 through the main pipe 132. The water quality control module (electronic metering pump) on the inlet pipe 130 automatically controls the water flow rate, accurately configures different concentrations of sulfate-stressed water and injects them into the corresponding independent test chambers. The brass manual valves on the inlet pipe 130 and the outlet pipe 113 can flexibly adjust the inlet and outlet water status. The temperature control module's temperature control host is connected to the digital temperature sensor (stainless steel encapsulated probe end) embedded in the lower side wall of the independent test chamber through the temperature conduction pipe 114, which monitors the water temperature of each chamber in real time and performs precise control. The scale 115 (wear-resistant and waterproof scale line) on the transparent side of the test chamber 110 can be used to observe the water level of each independent test chamber in real time. The arc-shaped dustproof plate 155 provides dust protection for the adjustment components such as the bidirectional threaded rod 151. Ultimately, it realizes the synchronous and accurate testing of the tolerance of largemouth bass under multiple sulfate stress concentrations, effectively reducing the interference of factors such as temperature fluctuations and uneven water quality.
