Description

Technical Field

[0001] This invention relates to the technical field of water sample testing equipment, specifically an automated bottle washer for water sample testing. Background Technology

[0002] Water sample monitoring refers to the monitoring of the physical properties, metallic compounds, non-metallic inorganic substances, organic compounds, biological substances, and hydrological and meteorological parameters of environmental water bodies (rivers, lakes, reservoirs, and groundwater, etc.) and water pollution sources (domestic sewage, hospital sewage, and industrial wastewater, etc.), as well as sediment monitoring. For tap water, the tap should be fully turned on to drain the stale water accumulated in the pipes before sampling. Groundwater quality is relatively stable, and generally, collecting instantaneous water samples can provide a good representative sample.

[0003] Water sample testing typically employs parallel sample analysis, which involves simultaneously analyzing two or more subsamples of the same sample under identical conditions. Therefore, multiple samples are collected at the same location or in the same area during the sampling process, resulting in a large number of samples and bottles. Furthermore, the sampling bottles and the analysis bottles differ in size and specifications, making cleaning difficult. Currently, manual cleaning with brushes is used, but the cleaning quality cannot be guaranteed. Reusing sampling bottles carries the risk of contaminating the water sample during secondary sampling, affecting the test results. Moreover, a significant amount of manpower and time is required to solve the cleaning problem of sampling and analysis bottles. Therefore, an automated cleaning device for water sample testing sampling and analysis bottles is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide an automated bottle washer for water sample testing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An automated bottle washer for water sample testing includes a housing and sample bottles. The housing mainly consists of a water supply system and a tray assembly. The housing has a built-in detachable tray assembly, which is connected to the housing's water supply system via a docking component.

[0007] The tray assembly includes a tray body, bottle troughs, tail drain holes, main drain holes, and a bottle washer. The tray body has an array of bottle troughs inside, and tail drain holes and main drain holes are located at both ends of the bottle troughs. The tray body is equipped with a pipe network that connects the tail drain holes and main drain holes. High-pressure water output from the water supply system is sent into the tail drain holes and main drain holes through the docking assembly and the pipe network. A ball that can extend into the bottle trough is installed in the tail drain hole. A bottle washer is installed in the main drain hole. The bottle troughs are equipped with evenly distributed brushes.

[0008] The bottle washer includes an outer tube, a tail ring, a slide groove, an inner tube, a spring, a limiting rod, a cleaning shaft, a through groove, a tail cap, and a slider. The outer tube contains a slidable and telescopic inner tube. A tail cap is installed on one side of the inner tube. A through groove is opened on the inner tube outside the tail cap. A limiting rod is fixed on the tail cap. The tail ring is slidably installed outside the limiting rod. A spring is installed between the inner tube and the tail ring. A slide groove is also opened on the inner side of the outer tube. A slider is installed on the tail ring within the slide groove. A cleaning shaft is installed on the other side of the tail cap.

[0012] As a further embodiment of the present invention: a portion of the baffle extends out of the inner tube, the left end of the baffle is conical, and the baffle contacts the opening of the sample bottle.

[0013] As a further embodiment of the present invention: the docking assembly consists of two pipe ports, namely a female port and a male port, which are respectively installed on the output end of the water supply system and on the tray body.

[0014] As a further embodiment of the present invention: the inside of the box is also provided with a tray and a buckle. The inside of the tray is equipped with a limiting plate by a miniature push rod. The top of the limiting plate is provided with a protrusion. The tray body is provided with a groove that matches the protrusion. The buckle is located on the top of the tray body. After the limiting plate is raised, it and the buckle clamp the tray body.

[0015] As a further embodiment of the present invention: the water supply system includes a solenoid valve, a booster pump, a control terminal, a timer switch and a contact sensor. The water source is supplied to the booster pump through the solenoid valve.

[0033] Please see Figures 1-9 In this embodiment of the invention, an automated bottle washer for water sample testing includes a housing 1 and sample bottles 14. The housing 1 is mainly composed of a water supply system and a tray assembly. The housing 1 has a detachable tray assembly inside. The tray assembly is connected to the water supply system of the housing 1 through a docking component 7. The housing 1 is in a closed state after the door 2 is closed. A sealing strip can be set between the doors 2 of the housing 1 to make it more airtight after closing and prevent water leakage. The tray assembly can be removed and replaced.

[0034] The tray assembly includes a tray body 5, bottle troughs 6, drain holes 12, main water holes 16, and a bottle washer 8. The tray body 5 has an array of bottle troughs 6 inside. The tray body 5 has drain holes 12 and main water holes 16 located at opposite ends of the bottle troughs 6. A pipe network connecting the drain holes 12 and main water holes 16 is installed inside the tray body 5. High-pressure water from the water supply system is delivered to the drain holes 12 and main water holes 16 through a connecting assembly 7 and the pipe network. A sphere 15, partially extending into the bottle troughs 6, is installed inside the drain hole 12. The bottle washer 8 is installed inside the main water hole 16. Evenly distributed brushes 13 are installed inside the bottle troughs 6. The structure of this tray assembly differs from a simple, ordinary tray; it has internal pipes... The water supply network allows water to flow around each sample bottle for cleaning. This cleaning method differs from that of a dishwasher, which sprays water from all sides, creating blind spots and affecting cleaning quality. When cleaning sample bottles, these blind spots increase, making it even more difficult to achieve a cleaning effect. Therefore, the water supply network allows for close-range spraying, resulting in a better cleaning effect. During sample bottle placement, the sample bottle is placed upright in the bottle slot 6. Water pressure is supplied to the network through the water supply system. The water pressure pushes the ball 15 inside the tail water hole 12 to advance it towards the bottom of the sample bottle 14. At the same time, under the action of water pressure, the ball 15 floats in the air, making it easier to rotate. The water pressure is then sprayed out through the tail water hole 12 for cleaning.

[0035] The bottle washer 8 includes an outer tube 801, a tail ring 802, a slide groove 803, an inner tube 804, a spring 805, a limiting rod 806, a cleaning shaft 808, a through groove 810, a tail cap 811, and a slider 812. The inner tube 804 is slidably telescopically mounted inside the outer tube 801. The tail cap 811 is mounted on one side of the inner tube 804. A through groove 810 is formed on the inner tube 804 outside the tail cap 811. The limiting rod 806 is fixed to the tail cap 811. The tail ring 802 is slidably mounted outside the limiting rod 806. A spring 805 is installed between the inner tube 804 and the tail ring 802. A slide groove 803 is also formed on the inner side of the outer tube 801. A slider 812 is located within the slide groove 803 on the tail ring 802. The cleaning shaft 808 is mounted on the other side of the tail cap 811. A brush 13 is provided on the outer side of the cleaning shaft 808. The bottle washer 8, as the main component for cleaning the inside of the sample bottle 14, needs to meet three main conditions: it needs to be convenient enough during the placement of the sample bottle 14 without obstructing its insertion and removal; it needs to have a telescopic function to access the inside of the bottle for washing; and it needs to supply water to the inside so that the water can circulate and carry away the residue. This application uses water pressure to control the sliding of the inner tube 804. When the water pressure enters the pipeline, it pushes the tail ring 802 and the inner tube 804 to slide outward until the slider 812 moves to the end of the slide groove 803. Under the action of water pressure, the spring 805 is stretched, and the tail cap 811 is pushed forward. The water pressure enters the inside of the sample bottle 14 from the inner tube 804 through the through groove 810 for cleaning and carrying away the residue through circulation. When the tail ring 802 and the tail cap 811 are in contact, they seal the bottle.

[0036] In a preferred embodiment, a rotary drive is also provided inside the bottle washer 8;

[0037] The rotary actuator includes a baffle 807 and a guide plate 809. The guide plate 809 is installed inside the inner tube 804. The baffle 807 is rotatably installed outside the cleaning shaft 808. The cleaning shaft 808 is fixed to the guide plate 809. The baffle 807 can rotate inside the inner tube 804. The inclination angle of the guide plate 809 and the baffle 807 is 45 degrees. The inclination angles of the guide plate 809 and the baffle 807 are opposite. With the presence of the baffle 807 and the guide plate 809, when water pressure passes through the guide plate 809, the inner tube 804 cannot rotate due to the restraint of the spring 805 and other components. Therefore, under the action of the guide plate 809, the water flow direction is tilted, scouring the baffle 807. The baffle 807 is pushed to rotate under the action of water pressure, thereby driving the sample bottle 14 to rotate together. The cleaning shaft 808 is fixed. The sample bottle 14 rotates and rubs against the brush 13 to perform cleaning.

[0038] In a preferred embodiment, a portion of the baffle 807 extends out of the inner tube 804. The left end of the baffle 807 is conical. The baffle 807 contacts the opening of the sample bottle 14. During the water pressure impact, the baffle 807 is pushed to rotate, causing the sample bottle 14 to rotate together. During the rotation of the sample bottle 14, it rubs against the inner and outer brushes 13, thereby achieving the effect of cleaning the sample bottle 14.

[0039] In a preferred embodiment, the docking assembly 7 consists of two pipe ports, a female port and a male port, which are respectively installed on the output end of the water supply system and on the tray body 5. The inside of the housing 1 is also provided with a tray support 4 and a tray buckle. The inside of the tray support 4 is equipped with a limiting plate 9 through a micro push rod 11. The top of the limiting plate 9 is provided with a protrusion, and the tray body 5 is provided with a groove 10 that matches the protrusion. The tray buckle is located on the top of the tray body 5. After the limiting plate 9 is raised, it clamps the tray body 5 with the tray buckle. During the process of water pressure output to the pipe network, the docking assembly 7 needs to maintain good connectivity. Therefore, after the door 2 is closed, the micro push rod 11 pushes the limiting plate 9 to clamp the tray buckle, so as to prevent the water pressure from blowing the docking assembly 7 open.

[0040] In a preferred embodiment, the water supply system includes a solenoid valve, a booster pump, a control terminal, a timer switch, and a contact sensor 3. Water is supplied to the booster pump through the solenoid valve. The booster pump pressurizes the water and sends it into the pipeline network of the tray assembly through the docking assembly 7. The timer switch and the contact sensor 3 are connected to the control terminal. When the contact sensor 3 is triggered, the control terminal controls the solenoid valve and the booster pump to open after the timer switch has completed its timeout. The housing 1 is provided with a door 2, and the contact sensor 3 is installed on the door 2. When the door 2 is closed, the contact sensor 3 triggers a signal to the control terminal, ensuring that the contact sensor 3 is triggered to guarantee safety during the cleaning process and prevent water leakage.

[0041] In a preferred embodiment, a wastewater discharge end is provided at the bottom of the housing 1. A water quality sensor is installed inside the wastewater discharge end. The data detected by the water quality sensor is transmitted to the control end. The control end controls the solenoid valve and booster pump switch according to the water quality detection value to realize automated cleaning. The equipment has two modes. One is that it can be timed by a timer switch to clean for a specified duration. After cleaning is completed, the equipment will automatically shut down. The other is that the data detected by the water quality sensor is transmitted to the control end. By analyzing the composition of the discharged wastewater, such as pH value, the control end controls the cleaning to automatically shut down.

[0042] The booster pump is also equipped with a back suction pipe, which consists of two parts: a direct connection pipe and a drain pipe. The direct connection pipe is connected in parallel with the booster pump. By adjusting the valve, the booster pump draws water back from the pipe network, creating a negative pressure that drives the inner pipe 804 and the tail ring 802 to retract, thereby resetting the bottle washer 8. Wastewater is connected to the wastewater discharge end through a pipeline. After cleaning, the bottle washer 8 is in an extended state, making it inconvenient to remove the bottle. Therefore, a back suction pipe is installed.

[0043] It should be noted that all the above embodiments belong to the same inventive concept, and the descriptions of each embodiment have different focuses. Where the description in a particular embodiment is not detailed, please refer to the description in other embodiments.

[0044] The embodiments described above are merely illustrative of implementation methods of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
