Description

Technical Field

[0001] This utility model relates to the field of rainwater harvesting technology, specifically a rainwater sample collector. Background Technology

[0002] Rainwater collectors are devices used to collect and store precipitation, widely used in environmental monitoring, meteorological research, and water quality analysis. They collect and store rainwater for convenient subsequent use. For example, a rainwater collector with a detachable filter element (CN211896308U) includes a collection tank for collecting rainwater and a filter device for filtering the rainwater. The filter device has a collection mechanism for collecting rainwater, and includes a first columnar protrusion detachably connected to the upper surface of the collection tank. The first columnar protrusion has a first through hole at its center, and a filter element for filtering rainwater is detachably connected to the first through hole. The filter element includes a first fixed post, and a filter screen structure is circumferentially provided on the outer wall of the first fixed post. A first annular protrusion is provided in the first through hole to prevent the filter screen structure from falling off. However, this rainwater collector with a detachable filter element still has the following drawbacks in actual use:

[0003] Traditional rainwater sample collectors suffer from evaporation after collection, and external insects can easily enter the container and contaminate the rainwater. Some collectors use filter cotton to filter the rainwater, but the microorganisms in the filter cotton grow too quickly, affecting the service life. To address these issues, there is an urgent need for innovative designs based on existing collectors. Utility Model Content

[0004] The purpose of this invention is to provide a rainwater sample collector to solve the problems mentioned in the background art. In traditional rainwater sample collectors, after collecting rainwater, the rainwater in the container will evaporate, and external insects can easily enter the container and contaminate the rainwater. In some collectors, the internal filter cotton is used to filter the rainwater, but the microorganisms in the filter cotton grow too quickly, affecting the service life.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a rainwater sample collector, comprising a water storage tank, a support frame fixed at equal angles on the outer side of the water storage tank, and a movable wheel rotatably mounted on the bottom of the support frame, and a water outlet valve provided at the bottom of the water storage tank.

[0006] It also includes: a drain valve, which is located on one side of the water storage tank, a water level gauge is installed on the drain valve, and an overflow pipe is connected to the other side of the water storage tank through a small ball valve, and a stainless steel leak box is connected to the bottom of the overflow pipe.

[0007] A water collection mechanism is located on top of the water storage tank.

[0008] Preferably, the water collection mechanism includes a water receiving tray disposed on the top of the water storage tank, with the edge of the water receiving tray overlapping the edge of the top of the water storage tank, and both the lower ends of the water receiving tray and the water storage tank being funnel-shaped, the water receiving tray being disposed to facilitate the collection of rainwater.

[0009] Preferably, the water receiving tray is symmetrically provided with connecting plates on both sides, and the inner wall of the connecting plate is in close contact with the outer wall of the water storage tank. The water receiving tray is provided with a through groove inside, and after the water receiving tray is installed on the top of the water storage tank, the connecting plate is in contact with the water storage tank.

[0010] Preferably, a mesh disc is provided on the inner side of the water receiving tray, and connecting blocks are symmetrically fixed on both sides of the mesh disc. The connecting blocks slide through the through groove, which ensures the stability of the mesh disc after the connecting blocks pass through the through groove.

[0011] Preferably, a drain box is provided at the opening at the bottom of the water receiving tray. The drain box is mesh-shaped and contains filter cotton. A float ball is attached to the top of the drain box. When the float ball comes into contact with rainwater, it floats up. When the rainwater flows into the water storage tank, the float ball will automatically fall down.

[0012] Preferably, an adjusting rod is inserted through the interior of the connecting plate, and the adjusting rod and the connecting plate are elastically slidably connected. The adjusting rod extends through the inner wall of the water storage tank into the connecting block, and a fixing hole is reserved in the connecting block. The adjusting rod can be used to lock the water tray and the mesh disc simultaneously.

[0013] Compared with the prior art, the beneficial effects of this utility model are: after collecting rainwater, this rainwater sample collector can effectively prevent the rainwater from evaporating inside the collection device, while blocking insects and slowing down the growth rate of microorganisms (microorganisms grow faster under light). Furthermore, after collecting rainwater, the collector facilitates the cleaning of impurities it traps. The specific details are as follows:

[0014] When it is necessary to clean the inside of the water collection mechanism, first pull the adjusting rod to slide on the connecting block to separate it from the fixing hole. Then the mesh disc can be removed from the water receiving tray for cleaning, and the leak box can also be removed from the water receiving tray for cleaning. Then pull the adjusting rod to separate it from the water storage tank, and the water receiving tray can be removed from the water storage tank for easy operation inside the water storage tank.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-6 The present invention provides the following technical solution:

[0024] Example 1: To address the problems existing in the prior art, this example provides the following technical solution: a rainwater sample collector, comprising a water storage tank 1, a support frame 2 fixed at equal angles on the outer side of the water storage tank 1, and casters 3 rotatably mounted on the bottom of the support frame 2; and a water outlet valve 4 provided at the bottom of the water storage tank 1; further comprising: a drain valve 5, located on one side of the water storage tank 1, with a water level gauge 6 mounted on the drain valve 5; an overflow pipe 7 connected to the other side of the water storage tank 1 via a small ball valve, and a stainless steel drain box 8 connected to the bottom of the overflow pipe 7; a water collection mechanism located on the top of the water storage tank 1; the water storage tank 1 is entirely made of 316 stainless steel. The water tank has a diameter of 400mm and can collect approximately 20L of rainwater. The rainwater flows through the collection mechanism into the storage tank 1 for collection. A small ball valve is installed on the side of the storage tank 1, which is connected to an overflow pipe 7 with an inner diameter of 8mm for overflow. Filter cotton is placed in the stainless steel drain box 8 to prevent insects from entering the storage tank 1 through the overflow port. A water level gauge 6 is installed to visually observe the rainwater level. A drain valve 5 is installed at the location of the water level gauge 6 to flush the water level gauge 6. At the same time, a real-time thermometer is installed on the storage tank 1 to measure the temperature of the rainwater inside the tank. The outlet valve 4 at the bottom of the storage tank 1 is used to collect the collected rainwater.

[0025] Example 2: Existing rainwater sample collectors experience evaporation after collection, and external insects can easily enter and contaminate the rainwater. Some collectors use filter cotton to filter the rainwater, but the rapid growth of microorganisms within the filter cotton affects its lifespan. Therefore, this example addresses this issue with the following technical solution: The water collection mechanism includes a water receiving tray 9 positioned on top of a water storage tank 1, with the edge of the tray 9 overlapping the edge of the top of the tank 1. Both the tray 9 and the tank 1 have funnel-shaped lower ends. Connecting plates 91 are symmetrically arranged on both sides of the tray 9, with the inner wall of the connecting plates 91 in close contact with the outer wall of the tank 1. A through groove 92 is provided inside the tray 9. A mesh disc 10 is provided inside the tray 9, with connecting blocks 101 symmetrically fixed on both sides of the mesh disc 10, and the connecting blocks 101 slide through the through groove 92. A drainage system is provided at the bottom opening of the tray 9. The water-leaking box 12 is mesh-shaped and contains filter cotton. A float ball 11 is attached to the top of the water-leaking box 12. An adjusting rod 13 runs through the connecting plate 91, and the adjusting rod 13 and the connecting plate 91 are elastically slidably connected. The adjusting rod 13 extends through the inner wall of the water storage tank 1 into the connecting block 101, which has a pre-drilled fixing hole 102. Rainwater can be collected in the water-receiving tray 9, then filtered by the mesh disc 10 and flows downwards. When the float ball 11 is buoyed by the water, it floats up. Simultaneously, the rainwater passes through the water-leaking box 12 and undergoes coarse filtration through the filter cotton before flowing into the water storage tank 1. The float ball 11 effectively prevents rainwater evaporation in the water storage tank 1, while also blocking insects and slowing microbial growth by obstructing the filter cotton. The stainless steel 60-mesh mesh disc 10, approximately 17cm in diameter, blocks sunlight and effectively prevents the float ball 11 from being blown away by the wind. Figures 4-6 When it is necessary to clean the inside of the water collection mechanism, first pull the adjusting rod 13 to slide on the connecting block 101 to separate it from the fixing hole 102. Then the mesh disc 10 can be removed from the water receiving tray 9 for cleaning, and the leak box 12 can also be removed from the water receiving tray 9 for cleaning. Then pull the adjusting rod 13 to separate it from the water storage tank 1, and the water receiving tray 9 can be removed from the water storage tank 1 for easy operation inside the water storage tank 1.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
