Description

Technical Field

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

[0002] Natural water quality refers to the physical and chemical properties and dynamic characteristics of natural water that has not been polluted by human activities. The physical properties mainly include water temperature, color, transparency, smell and taste. The chemical properties are determined by the gases, ions, molecules, colloids and suspended solid components, microorganisms and the content of these substances dissolved and dispersed in natural water. Natural water quality needs to be tested when used, and at this stage it is generally accomplished using water quality testing devices.

[0003] For example, a water quality testing device for drinking natural water production disclosed in Chinese patent CN220231709U can increase the distance between the elastic rods to adapt to test tubes of different widths. At the same time, the elastic material on the arc plate can increase the friction on the one hand to prevent the test tube from moving and play a better fixing role. On the other hand, it can absorb part of the force through elastic deformation to protect the test tube and avoid scratches on the test tube. It is more convenient to take it and achieves the effect of stability.

[0004] Although this structure can stably clamp the test tube, multiple sampling is required during the natural water quality testing process. The samples cannot be tested continuously and the sampling process is cumbersome. Therefore, we propose a detection device for natural water quality that can continuously test samples and avoid reciprocating replacement of clamped samples to improve detection efficiency.

[0009] Preferably, the outer wall of the inclined bar is slidably arranged inside the vertical groove, the end of the inclined bar away from the spring is arranged at an inclined surface, and the inclined block is arranged at an inclined surface. When the inclined block contacts the inclined surface of the inclined bar, the inclined block squeezes the inclined bar, and the inclined bar slides inside the vertical groove. The inclined block does not serve as a limit for the movable disk, so that the movable disk can rotate.

[0010] Preferably, the first extrusion block and the second extrusion block are hemispherically arranged, and the first extrusion block is arranged in spherical contact with the inclined block. Under the restriction thereof, when the first extrusion block and the second extrusion block are squeezed, the second extrusion block drives the placement plate to move upward, causing the test tube clamped on the top surface of the placement plate to vibrate accordingly.

[0011] Preferably, the sliding column fixedly mounted on the outer wall of the clamping plate is slidably arranged with the inclined groove opened on the inner wall of the slide groove, and the outer wall of the clamping plate and the inner wall of the slide groove are slidably arranged. Under their restriction, when the pull ring moves upward, the four clamping plates can be driven to open.

[0012] Preferably, there are four clamping plates distributed in a cross shape with the center of the tube placed in the center. The end of the clamping plate away from the sliding column is made of rubber material. The test tube can be stably clamped by the rubber clamping plate, while preventing the clamping plate from damaging the test tube.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The detection device for natural water quality is composed of a detection component as one component. When it is necessary to detect the natural water quality, multiple detection test tubes for sampling are clamped on the top surface of the placement tray. At this time, the sample inside the detection test tube needs to be mixed with the detection reagent, and the motor is started. The reciprocating screw rod fixedly installed at its output end rotates accordingly, causing the movable tray set on its outer wall to rotate forward. When the inclined surface of the inclined block fixedly installed on the side wall of the movable tray contacts and squeezes the inclined surface of the inclined bar, the inclined bar slides toward the inside of the vertical groove and squeezes the spring. At this time, the movable tray is not restricted. When the reciprocating screw rod rotates, it can drive the movable tray to rotate accordingly, and the first extrusion block fixedly installed on the outer wall of the movable tray rotates accordingly. Since the placement tray and the outer wall of the limit rod are slidingly arranged, and the second extrusion block is fixedly installed on the bottom of the placement tray, when the first extrusion block fixedly installed on the outer wall of the movable tray contacts and squeezes the second extrusion block fixedly installed on the bottom of the placement tray, the placement tray slides up and down on the outer wall of the limit rod to generate a vibration effect, so that the detection test tube clamped on the top surface of the placement tray vibrates accordingly. The sample and the detection reagent are fully mixed. When it is necessary to detect the mixture inside the detection test tube, the motor is turned on to reverse, so that the reciprocating screw rod is reversed accordingly, and the side of the first extrusion block fixedly installed on the side wall of the moving disk away from its inclined surface contacts the side of the inclined strip away from its inclined surface, so that the first extrusion block is clamped with the inclined strip. At this time, the moving disk will not rotate under the restriction of the first extrusion block. Under the action of the reciprocating screw rod and the moving disk sleeve, the rotating reciprocating screw rod drives the moving disk to reciprocate, so that the moving disk pushes the placement disk arranged above it to move accordingly, so that the placement disk and the outer wall of the limit rod slide stably, and the placement disk drives the detection test tube clamped above it to move toward the detection device. When the detection distance between the detection test tube and the detection device is appropriate, the motor stops working, and the detection device rotatably connected to the top surface of the box body can detect the mixture inside the detection test tube. When it is necessary to detect other detection test tubes, the detection device can be slid with the center of the reciprocating screw rod as the rotation center, so that multiple detection test tubes can be quickly detected.

[0015] 2. The natural water quality detection device is composed of a clamping assembly as one of its components. When the test tube needs to be clamped, the pull ring is pushed upward so that the slide groove opened on the outer wall of the pull ring moves accordingly, and the inner wall of the inclined groove opened on the inner wall of the slide groove slides and squeezes with the sliding column fixedly installed on the outer wall of the clamping plate, so that the sliding column slides on the inner wall of the inclined groove, driving the four clamping plates to be in an open state. At this time, the test tube is placed inside the placement tube, and the pull ring is released. Under the action of its own gravity, the pull ring slides downward, and the inner wall of the inclined groove is squeezed with the outer wall of the sliding column, so that the sliding column drives the clamping plates to gather, and the four clamping plates clamp the outer wall of the test tube. The sponge block can buffer the test tube to prevent the test tube from directly contacting and colliding with the inner wall of the placement tube. BRIEF DESCRIPTION OF THE DRAWINGS

Under the action of the sleeve of the reciprocating screw rod 413 and the movable disk 414, the rotating reciprocating screw rod 413 drives the movable disk 414 to reciprocate, so that the movable disk 414 pushes The placing plate 421 arranged above it moves accordingly, so that the placing plate 421 and the outer wall of the limiting rod 420 slide stably, and the placing plate 421 drives the detection test tube 5 clamped above it to move toward the detection device 6.
