Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection, in particular to a device for detecting microorganisms of domestic water. Background Art

[0002] Water is a basic need for human life, but polluted water may contain harmful substances such as bacteria, viruses, parasites, heavy metals, chemicals, etc. These pollutants may cause damage to the human digestive system, nervous system, respiratory system, etc., and long-term intake may even cause chronic diseases and cancer.

[0003] Therefore, through water quality testing, we can ensure the safety of drinking water, prevent waterborne diseases, protect human health, and maintain environmental health: water pollution not only affects human health, but may also cause damage to aquatic ecosystems. For example, excessive nutrients (such as nitrogen and phosphorus) may lead to eutrophication of water bodies, trigger massive reproduction of algae, consume dissolved oxygen in the water, and cause the death of fish and other aquatic organisms. Through water quality testing, pollution problems can be discovered in time and corresponding measures can be taken to maintain the health of the water ecosystem. Water quality testing is an important part of water resources management. By regularly testing water quality, we can understand the status of water resources and provide a basis for formulating reasonable water resources development and utilization plans. At the same time, water quality testing can also help assess the degree of pollution in water bodies and provide a reference for formulating environmental protection policies.

[0004] However, in the prior art, when testing water sources, it is necessary to sample wastewater from different areas and after use before testing and processing. The current testing device cannot well store and clamp the test tube body after sampling. When the test tube body is placed inside the testing device, it will shake due to the movement of the testing device, causing the liquid in the test tube body to leak out, affecting the storage environment inside the testing body and the final result of the water quality test. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a microbial detection device for domestic water, so as to solve the problem that when testing water sources in the prior art, it is necessary to sample wastewater from different areas and after use and then perform testing and processing. The current detection device cannot well store and clamp the test tube body after sampling. When the test tube body is placed inside the detection device, it will shake due to the movement of the detection device, thereby causing the liquid in the test tube body to leak out, affecting the storage environment inside the detection body and affecting the final result of the water quality detection.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a kind of domestic water microorganism detection equipment, including a detection body, a working block is fixedly installed in the detection body, a storage block is slidably installed in the working block, a movable block is fixedly connected to the outside of the storage block, a limit plate is fixedly installed in the storage block, a plurality of groups of test tube bodies are buckled and installed on the limit plate, a plurality of groups of card slots for matching with the test tube bodies are provided on the limit plate, a convex ring is fixedly installed on the outside of the top of the test tube body, a sealing cover is arranged in the test tube body, and a first air guide is fixedly installed on the top of the working block.

[0007] By adopting the above technical scheme, when in use, different test liquids are collected through the test tube body, and then the test tube body is sealed by the sealing cover to prevent the test liquid from leaking. Secondly, the test tube body is placed in the limit plate in turn through the slot on the limit plate. After the test tube body is placed, the movable block is pushed to retract the storage block into the working block. When the storage block is retracted into the working block, the storage block continuously squeezes the pressure plate to move the pressure plate to the right, thereby moving the piston block to the right in the gas storage block to squeeze the gas in the gas storage block, and the one-way air outlet pipe cooperates with the first air guide pipe and the second air guide pipe. , the gas can be guided into the clamping structure, so that the sealing cover and the convex ring can be clamped and fixed. Because the clamping structure is located on both sides of the test tube body, the end of the test tube body can pass through the clamping structure. With this structure, when the test tube body is located inside the storage block, the test liquid in the test tube body will not leak due to the bumps and slow movements of the detection body during the movement. The sealing cover can be tightly blocked in the test tube body through the clamping structure. When the storage block is pulled out of the working block, the sealing cover can also be opened more easily, which can improve the practicality of the entire domestic water microbial detection equipment.

When the gas in the gas storage block fills the air inlet, the gas delivery pipe and the fixed block cooperate with each other, so that the clamping block can extend out of the fixed block, and then the convex ring and the sealing cover are clamped and fixed, so that the sealing cover can be tightly blocked in the test tube body, so as to achieve a better sealing effect and prevent the test solution from leaking from the test tube body. Secondly, the friction between the clamping block, the convex ring and the sealing cover can be increased by the rubber pad at the bottom of the clamping block, so that the clamping block can clamp and fix the top of the test tube body more firmly.

[0010] The utility model is further configured such that a first connecting tube is connected to one side of the first air guide tube, the first connecting tube passes through the detection body, an air release valve is provided at the end of the first connecting tube, and the air release valve is located on the back of the detection body.

[0012] The utility model is further configured that a movable groove for cooperating with the working block is opened on the inner side of the movable block, and a slot for cooperating with the first spring and the pressure plate is opened on the right side of the working block.

[0013] By adopting the above technical solution, the movable groove can enable the outer frame of the movable block to be inserted into the detection body to achieve a certain sealing effect. Secondly, the slot opened on the right side of the working block can be used in conjunction with the pressure plate and the first spring to flexibly cooperate with the storage block.

[0014] The utility model is further configured that a second spring is fixedly installed between the piston block and the gas storage block.

[0015] By adopting the above technical solution, the second spring between the piston block and the gas storage block can assist the piston block to move smoothly in the gas storage block. When the movable block and the storage block need to be pulled out of the detection body, the gas is released through the air release valve, so that the clamping structure is unlocked and no longer clamps the test tube body. Then, the performance of the second spring itself can assist the piston block to quickly return to its initial position.

[0016] The utility model is further configured that a one-way air intake pipe is symmetrically arranged on the right side of the air storage block, and the one-way air intake pipe runs through the side wall of the detection body.

[0017] By adopting the above technical solution, when the movable block and the storage block are pulled outward, the first spring can drive the pressure plate and the connecting rod to move outward at the same time, so that the piston block moves outward at the same time. When the piston block moves outward, negative pressure is generated in the gas storage block, so that gas is drawn from the outside into the gas storage block through the one-way air inlet pipe, so as to cooperate with the pressure plate, the connecting rod and the piston block for repeated recycling.

[0018] In summary, the utility model mainly has the following beneficial effects:

[0019] 1. The utility model collects different test liquids through the test tube body, and then seals the test tube body through the sealing cover to prevent the test liquid from leaking. Secondly, the test tube body is placed in the limit plate in sequence through the card slot on the limit plate. After the test tube body is placed, the movable block is pushed to retract the storage block into the working block. When the storage block is retracted into the working block, the storage block continuously squeezes the pressure plate to move the pressure plate to the right, thereby moving the piston block to the right in the gas storage block to squeeze the gas in the gas storage block. Through the mutual cooperation between the one-way air outlet pipe and the first air guide pipe and the second air guide pipe, the gas can be The body is guided into the clamping structure, so that the sealing cover and the convex ring can be clamped and fixed. Because the clamping structure is located on both sides of the test tube body, the end of the test tube body can pass through the clamping structure. With this structure, when the test tube body is located inside the storage block, the test liquid in the test tube body will not leak due to the bumps and slow movements of the detection body during the movement. The sealing cover can be tightly blocked in the test tube body through the clamping structure. When the storage block is pulled out of the working block, the sealing cover can also be opened more easily, which can improve the practicality of the entire domestic water microbial detection equipment.

Secondly, the test tube body 12 is placed in the limiting plate 11 in sequence through the card slot on the limiting plate 11. After the test tube body 12 is placed, the movable block 2 is pushed to retract the storage block 9 into the working block 8.

Secondly, the groove provided on the right side of the working block 8 can be used in conjunction with the pressure plate 13 and the first spring 14 to flexibly cooperate with the storage block 9. Again, the second spring 18 between the piston block 17 and the gas storage block 15 can assist the piston block 17 to move smoothly in the gas storage block 15. When the movable block 2 and the storage block 9 need to be pulled out of the detection body 1, the gas is released through the air release valve 3, so that the clamping structure 19 is unlocked and no longer clamps the test tube The main body 12 is clamped, and then the performance of the second spring 18 itself can assist the piston block 17 to quickly return to the initial position. Finally, when the movable block 2 and the storage block 9 are pulled outward, the first spring 14 can drive the pressure plate 13 and the connecting rod 16 to move outward at the same time, so that the piston block 17 moves outward at the same time. When the piston block 17 moves outward, negative pressure is generated in the gas storage block 15, so that gas is drawn from the outside into the gas storage block 15 through the one-way air inlet pipe 4, so as to cooperate with the pressure plate 13, the connecting rod 16 and the piston block 17 for repeated recycling.
