Detailed Implementation
[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.
[0022] The core of this application is to provide a liquid level detection device for automatically detecting the remaining reagent in a reagent bottle, thereby saving labor costs.
[0023] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0024] Figure 1 This is a structural diagram of a liquid level detection device provided in the embodiment of the application. Figure 2 A structural diagram of another liquid level detection device provided in the application embodiment is shown below. Figure 1 and Figure 2 As shown, the liquid level detection device includes: a controller 1, a liquid level detection component 2, an alarm device 3, and a support component; the support component includes a support platform 401, a first telescopic rod 402, and a second telescopic rod 403. The bottoms of the first telescopic rod 402 and the second telescopic rod 403 are both connected to the support platform 401. The support platform 401 is used to support the reagent bottle 5. The first telescopic rod 402 and the second telescopic rod 403 are located on both sides of the reagent bottle 5. The liquid level detection component 2 is mounted on the first telescopic rod 402 and the second telescopic rod 403. The controller 1 is connected to the liquid level detection component 2 and the alarm device 3 respectively.
[0025] This application embodiment does not specifically limit the connection method between the first telescopic rod 402 and the second telescopic rod 403 and the support platform 401, and a fixed connection method can be adopted. The first telescopic rod 402 and the second telescopic rod 403 are symmetrically arranged on both sides of the reagent bottle 5. The reagent bottle 5 is used to store chemical reagents. The liquid level detection component 2 can be a photoelectric sensor. The light source and the light source receiver are respectively arranged on the first telescopic rod 402 and the second telescopic rod 403, and the light source and the light source receiver need to be located in the same height direction of the reagent bottle 5. The alarm device 3 includes an indicator light and / or a buzzer. When the liquid level detection component 2 detects that the reagent bottle 5 is lower than the alarm liquid level, the controller 1 controls the alarm device 3 to issue an alarm prompt.
[0026] This application provides a liquid level detection device, comprising: a controller, a liquid level detection component, an alarm device, and a support component. The support component includes a support platform, a first telescopic rod, and a second telescopic rod. The bottoms of both the first and second telescopic rods are connected to the support platform, which supports reagent bottles. The first and second telescopic rods are located on both sides of the reagent bottle. The liquid level detection component is mounted on the first and second telescopic rods. The controller is connected to both the liquid level detection component and the alarm device. Through the cooperation of the controller 1, the liquid level detection component, and the alarm device, an alarm can be triggered when the reagent level in the bottle falls below the alarm level, reminding staff to replenish the liquid in time. Therefore, manual monitoring of the remaining reagent level in the bottle is unnecessary, saving labor costs. Furthermore, by setting the first telescopic rod 402 and the second telescopic rod 403, the height of the liquid level detection component can be adjusted according to actual needs, thereby achieving the purpose of adjusting the alarm liquid level height of the reagent bottle.
[0027] Based on the above embodiments, the support platform 401 of this application embodiment is provided with a positioning groove for positioning the reagent bottle 5. This application embodiment does not specifically limit the shape of the positioning groove, and it can be adapted to the bottom shape of the reagent bottle 5. By setting the positioning groove, it is convenient for staff to place the reagent bottle 5 in the correct position, so that the liquid level detection component 2 can accurately detect the liquid level inside the reagent bottle 5.
[0028] Based on the above embodiments, the positioning groove in this application embodiment is provided with sliding grooves on both sides, and the bottom of the first telescopic rod 402 and the second telescopic rod 403 are provided with sliders. The first telescopic rod 402 and the second telescopic rod 403 are slidably connected to the support platform 401 through the sliders and sliding grooves.
[0029] In this embodiment, the telescopic rod is slidably connected to the support platform 401 via a slider and a groove. The sliding connection can change the distance between the first telescopic rod 402 and the second telescopic rod 403, making it easy to adapt to reagent bottles 5 of different specifications.
[0030] Based on the above embodiments, such as Figure 2 As shown, the embodiments of this application also include a first elastic member 6, a first abutting part 7, a second elastic member 8, and a second abutting part 9. The first elastic member 6 is connected to the first telescopic rod 402 and the first abutting part 7, respectively. The second elastic member 8 is connected to the second telescopic rod 403 and the second abutting part 9, respectively. The first abutting part 7 and the second abutting part 9 are used to abut against the side wall of the reagent bottle 5 under the restoring force of the first elastic member 6 and the second elastic member 8.
[0031] In this embodiment, the first elastic element 6 and the second elastic element 8 can be springs, and the first abutting part 7 and the second abutting part 9 can be arc-shaped elastic elements. The arc-shaped elastic elements can deform to hold the body of the reagent bottle 5, fitting well with the bottle body, facilitating the fixation of the reagent bottle 5 and preventing it from tipping over. The arc-shaped elastic elements can be made of silicone material, which will not damage the body of the reagent bottle 5. If the first abutting part 7 and the second abutting part 9 fix the reagent bottle 5 under the restoring force of the first elastic element 6 and the second elastic element 8, and the first telescopic rod 402 and the second telescopic rod 403 are slidably connected to the support platform 401, a locking device needs to be provided on the slider. The locking device is used to position the slider at a set position in the slide groove. The locking device can be a bolt. When the bolt is tightened, one end of the bolt passes through the slider and abuts against the slide groove, which can fix the slider at a certain position in the slide groove.
[0032] Based on the above embodiments, both the first telescopic rod 402 and the second telescopic rod 403 in this application embodiment include an outer rod and an inner rod. The inner rod is sleeved inside the outer rod. The outer rod is provided with a plurality of through holes spaced apart in the height direction. The outer wall of the inner rod is provided with an elastic button. The elastic button is selectively engaged with one of the through holes to change the relative position of the inner rod and the outer rod.
[0033] Pressing the elastic button retracts it into the outer rod, causing the inner rod to slide along the outer rod. This allows the elastic button to engage with one of the multiple through holes on the outer rod, thus changing the overall length of the telescopic rod. In this embodiment, the first telescopic rod 402 and the second telescopic rod 403 have simple structures, low cost, and are easy to operate.
[0034] Based on the above embodiments, the liquid level detection component 2 of this application includes an infrared emitting probe 201 and an infrared receiving probe 202. The infrared emitting probe 201 is disposed on the first telescopic rod 402, and the infrared receiving probe 202 is disposed on the second telescopic rod 403. The infrared emitting probe 201 and the infrared receiving probe 202 are located at the same height in the reagent bottle 5.
[0035] Infrared emitting probe 201 and infrared receiving probe 202 can be fixed to the first telescopic rod 402 and the second telescopic rod 403 respectively by bolts. The principle of monitoring the liquid level is as follows: Infrared emitting probe 201 intermittently emits infrared signals. Since the reagent in the bottle will block the infrared receiving probe 202 from receiving infrared light, the absence of infrared signal by infrared receiving probe 202 indicates that the reagent in reagent bottle 5 is not below the alarm liquid level. When the reagent is below the alarm liquid level, infrared receiving probe 202 will receive an infrared signal and feed this status back to controller 1. Controller 1 sends a command to alarm device 3, and alarm device 3 issues an alarm prompt.
[0036] Based on the above embodiments, this application embodiment also includes a storage tank, a replenishment tube 10, and an infusion pump connected to the controller 1. The top of the reagent bottle 5 is provided with a sealing cap. One end of the replenishment tube 10 is sealed and inserted into the reagent bottle 5 through the sealing cap, and the other end of the replenishment tube 10 is connected to the storage tank through the infusion pump.
[0037] By setting up a storage tank and an infusion pump, automatic replenishment of reagent bottle 5 can be achieved, thereby further saving labor costs. When the liquid level detection component 2 detects that the liquid level in reagent bottle 5 is lower than the alarm level, the controller 1 activates the alarm device 3 and simultaneously starts the infusion pump to replenish the reagent in the storage tank into reagent bottle 5.
[0038] Based on the configuration of the storage tank and the infusion pump, the liquid level detection assembly 2 includes at least two sets. The first set of liquid level detection assemblies 2 is located near the bottom of the reagent bottle 5, and the second set of liquid level detection assemblies 2 is located near the top of the reagent bottle 5.
[0039] When the first set of liquid level detection components located near the bottom of reagent bottle 5 detects that the liquid level of reagent bottle 5 is lower than the alarm level, the infusion pump can be turned on to replenish the liquid in reagent bottle 5; when the second set of liquid level detection components located near the top of reagent bottle 5 detects that the liquid level of reagent bottle 5 is higher than the set level, the infusion pump can be stopped to stop the replenishment of reagent bottle 5, that is, the replenishment of reagent bottle 5 is completed.
[0040] Based on the above embodiments, this application embodiment further includes a cleaning water tank, a cleaning pipe 11, and a cleaning pump connected to the controller 1. One end of the cleaning pipe 11 is sealed with a cap and inserted into the reagent bottle 5, while the other end of the cleaning pipe 11 is connected to the cleaning water tank via the cleaning pump. The controller 1 can periodically start the cleaning pump so that it delivers cleaning water from the cleaning water tank to the reagent bottle 5 to clean it, thereby achieving automatic cleaning of the reagent bottle 5. Of course, a drain valve can be connected to the bottom of the reagent bottle 5 to facilitate the discharge of cleaning wastewater.
[0041] Based on the above embodiments, this application embodiment further includes a rotary motor and a stirring rod. One end of the stirring rod is sealed and inserted into the reagent bottle 5 via a sealing cap, extending to near the bottom of the reagent bottle 5. The other end of the stirring rod is connected to the rotary motor. By providing a rotary motor and a stirring rod, precipitation of the reagent in the reagent bottle 5 can be effectively prevented.
