Description

Technical Field

[0001] This utility model belongs to the field of water environment testing technology, and specifically relates to a device for shaking water sample reagents for environmental testing. Background Technology

[0002] Water environment testing is the process of determining the types of pollutants in water bodies, the concentration of various pollutants, and their changing trends, and evaluating the water quality status. This includes unpolluted and polluted natural water (rivers, lakes, seas, and groundwater) as well as various types of industrial wastewater. Water quality testing can provide data and information for water environment management and can provide a basis for evaluating the water quality status of rivers and oceans.

[0003] Currently, in water environment testing, after sample collection, the water is typically mixed with chemical reagents for reaction. After sufficient reaction, the mixture is ready for subsequent analysis. To accelerate the reaction, the mixture is often shaken; currently, specialized equipment is commonly used for this shaking operation. This reaction and testing process is usually conducted in a laboratory to facilitate the collection and recording of experimental procedures and results.

[0004] For example, in the prior art publication CN 223570534 U, an environmental testing water sample reagent shaking device is described. In this design, a motor drives a swing arm to swing, and the other end of the swing arm moves within a movable groove, pushing a movable shaft to reciprocate up and down within a bushing. The reciprocating motion of the movable shaft clamps the reagent tube through a fixed clamp, producing a continuous shaking effect. Simultaneously, to prevent collisions and spillage during transportation, a pressure plate is installed in the sedimentation chamber to protect the top end of the test tube. However, the drawbacks are also quite obvious: it does not consider the possibility of reagent liquid spilling out of the test tube along the reagent bottle opening during shaking, i.e., there is a risk of liquid spilling out of the test tube.

[0005] Another device with the same drawbacks as mentioned above is a mixing and shaking device for reagent detection, with announcement number CN222401174U.

[0006] Therefore, it can be expected that in order to avoid shaking out the reagent liquid, only slow and low-frequency shaking can be performed, which is inefficient. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a shaking device for water sample reagents in environmental testing. By using a fixing mechanism, the port of the reagent bottle can be sealed with a tension spring, a pressure plate, and a fixing plate, thereby preventing the reagent liquid from being shaken out. It can also increase the motor speed, thereby increasing the shaking frequency and shaking effect of the reagent bottle.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] An environmental testing water sample reagent shaking device includes a base plate and a support plate. The base plate is provided with a power mechanism, and the support plate is provided with a fixing mechanism and a clamp. The clamp is located on one side of the fixing mechanism and cooperates with it to clamp and fix the reagent bottle.

[0010] The base plate is provided with a guide post and a slidably connected support plate. The guide post is provided with a limiting plate and a sleeved first spring. The first spring touches the support plate and the limiting plate. The power mechanism, in conjunction with the first spring, drives the support plate to move up and down along the guide post to achieve uniform shaking of the water sample reagent in the reagent bottle.

[0011] The fixing mechanism includes a fixing post, a sleeve, a screw, a pressure plate, a tension spring, and a shaft. The fixing post is fixedly connected to the bearing plate and has a threaded hole at its center. The sleeve has a through hole, the screw is inserted into the through hole, the screw has an insertion hole, and the shaft is inserted into the insertion hole. Both ends of the shaft have through-bars that restrict the sleeve's up-and-down sliding by the through-bars and the nuts at the ends of the screw. A support plate is provided on one side of the fixing post. A guide shaft is provided at one end of the sleeve and is slidably connected to the support plate. A limit rod and a pin are provided at the top of the sleeve, and a first positioning shaft is provided at the bottom of the sleeve.

[0012] One end of the pressure plate is provided with a U-shaped frame, and the U-shaped frame is rotatably connected to a pin shaft; a second positioning shaft is provided on the U-shaped frame; a fixed shaft is provided on the pressure plate and slidably connected; a fixed plate is provided at the end of the fixed shaft and a limiting plate is provided at one end of the fixed shaft; a second spring is provided on the fixed shaft and the second spring contacts the fixed plate and the pressure plate; a sealing gasket is provided on the fixed plate.

[0013] The two ends of the tension spring are respectively connected to the first positioning shaft and the second positioning shaft.

[0014] The power mechanism includes a motor, a central shaft, and bearing housings; the bearing housings are provided with a pair and fixedly connected to the base plate; the two ends of the central shaft are rotatably connected to the bearing housings; the end of the central shaft is provided with a synchronous pulley; the motor is fixed on the base plate; the end of the motor shaft is provided with a synchronous pulley and connected to the synchronous pulley at the end of the central shaft via a synchronous belt; the central shaft is provided with a cam.

[0015] Preferably, the bottom of the clamp is provided with a lead screw, which is fixed by engaging with the threaded hole in the bearing plate. At the same time, different sizes of clamps can be replaced according to the reagent bottle model to adapt to clamping.

[0016] Preferably, one end of the pressure plate is provided with a lever to facilitate switching the pressure direction by moving the pressure plate.

[0017] A protective cover is mounted on the base plate, and one end of the protective cover is hinged to the base plate. The protective cover is transparent.

[0018] The advantages of this utility model compared with the prior art are as follows:

[0019] Firstly, a fixing mechanism is set up in this solution. The fixing plate in the fixing mechanism can seal the port of the reagent bottle, which can prevent the reagent liquid from shaking out during the shaking process. This can increase the speed of the motor, thereby increasing the shaking frequency of the reagent bottle, as well as the shaking effect and efficiency of the reagent.

[0020] Secondly, the application process of the fixing mechanism and fixing plate is extremely simple and convenient, and the pressing and sealing effect is obvious. When using it, you only need to turn the pressure plate around the pin to rotate the pressure plate to the other side and support it with the limit rod, which provides a completely open space for the reagent bottle to be inserted into the clip. After the reagent bottle is inserted into the clip, the pressure plate can be rotated back to its original position. At the same time, the fixing plate is elastically connected to the pressure plate rib through the fixing shaft, the second spring, and can adapt to the sealing process of the reagent bottle port.

[0021] Finally, since the screw and the sleeve are connected movably, rotating the screw can also drive the sleeve to move up and down along the guide shaft to adjust the height of the pressure plate, thus adapting to the height of the reagent bottle. Attached Figure Description
