Description

Technical Field

[0001] This utility model belongs to the field of water sample filtration technology, and in particular relates to a water sample filtration device for microbial environmental testing. Background Technology

[0002] By detecting the types, quantities, community structure, and functions of microorganisms in water samples, we can understand the degree of environmental pollution and ecological conditions. For example, in water quality monitoring, coliform bacteria are a commonly used microbial indicator to indicate that water bodies are contaminated by feces. If the number of coliform bacteria in the water exceeds the standard, it indicates that there may be health and safety hazards in the water body.

[0003] When testing water samples, a water sample filtration device for microbial environmental testing is required. However, existing water sample filtration devices usually require the use of additional filter cups. This can lead to the purchase of incompatible filter cups or the inability to prepare the filter cups in time when filtration is needed. This may result in wasting unnecessary time and reducing work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a water sample filtration device for microbial environmental testing. Specifically, by rotating a rocker arm, a worm gear rotates on the left side of the second support plate. The worm gear drives a worm wheel to rotate on the corresponding side of the two first support plates. Simultaneously, a gear drives a rack to slide between two fixed frames, thereby causing the rack to move the support frame and the filter cup. This allows for the built-in filter cup, which can be easily removed by rotating the rocker arm, thus solving the problem that existing water sample filtration devices typically require additional filter cup preparation, which may result in the filter cup not being ready immediately, reducing work efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a water sample filtration device for microbial environmental testing, comprising a protective shell and filter cups. Two fixed brackets are fixedly connected to the inner bottom wall of the protective shell. A rack is slidably connected to one side of each of the two fixed brackets. Three filter cups are provided. Two support brackets are fixedly connected to one side of each of the three filter cups. The right side of the rack is fixedly connected to the left side of the two support brackets. A support plate is fixedly connected to the left side of each of the two fixed brackets. A worm gear is provided on one side of each of the two support plates. A gear is fixedly connected to the back of the worm gear. The gear and worm gear are rotatably connected to one side of each of the two support plates via a shaft. The right side of the gear meshes with the left side of the rack. A worm is meshed with the top of the worm gear. A second support plate is fixedly connected to the top of the two fixed brackets. The right side of the worm is rotatably connected to the left side of the second support plate. A rocker arm is fixedly connected to the left side of the worm arm. The left side of the rocker arm penetrates the left side of the protective shell and extends to the outside. Rotating the rocker arm moves the rack via the worm gear and worm, allowing the filter cups to be removed. This design facilitates use and improves work efficiency.

[0007] Furthermore, connecting blocks are fixedly connected to the right sides of the two support frames, and sliding rods are fixedly connected to the bottom of the connecting blocks. The two support frames provide stable support for the filter cup, and the filter cup can be moved simultaneously when the support frames move, thus improving the stability and reliability of the device.

[0008] Furthermore, a support rod is slidably connected to the outer surface of the slide rod, and the bottom of the support rod is fixedly connected to the inner wall of the bottom of the protective shell. When the filter cup moves up and down, the slide rod slides on the inner wall of the support rod, providing a stable running trajectory for the filter cup and limiting its movement, thereby further improving the stability of the device.

[0009] Furthermore, a sewage tank is fixedly connected inside the protective shell, and a drawer is slidably connected to the inner wall of the sewage tank. A handle is fixedly connected to the front of the drawer. The sewage tank is used to collect filtered sewage. After filtration is completed, the handle is pulled to remove the drawer and pour out the sewage to avoid direct discharge and environmental pollution.

[0010] Furthermore, a drain pipe is fixedly connected to the top of the sewage tank, and a filter port is fixedly connected to the top of the drain pipe. An electromagnetic valve is installed inside the drain pipe, which controls the start and stop of water sample filtration at any time, thus improving the flexibility of the device.

[0011] Furthermore, a sealing ring is fixedly connected to the bottom of the filter port. The bottom of the sealing ring contacts the inner wall of the bottom of the filter cup. The sealing ring ensures that the filter cup and the filter port are in close contact, thereby preventing water from leaking out from the gaps and contaminating other parts inside the protective shell, thus further improving the stability of the device.

[0012] Furthermore, the inner wall of the filter cup is in contact with the outer surface of the filter port, and the inside of the filter cup is slidably connected to the outer surface of the drain pipe. When the filter cup moves up and down, its inside slides on the outer surface of the drain pipe, making the movement trajectory of the filter cup more stable and further improving the stability of the device.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model features a filter cup. Specifically, by rotating a rocker arm, a worm gear is driven to rotate on the left side of the second support plate. The worm gear drives a worm wheel to rotate on the corresponding side of the two first support plates. At the same time, a gear drives a rack to slide between two fixed frames, thereby causing the rack to move the support frame and the filter cup. In this way, the filter cup is built in and can be removed by rotating the rocker arm when in use, which is convenient and improves work efficiency.

[0015] 2. This utility model incorporates a wastewater tank. Specifically, water samples flow into the wastewater tank through a filter cloth and filter outlet from a drain pipe. After the water sample is filtered, the handle is pulled to slide the drawer against the inner wall of the wastewater tank, allowing the drawer to be removed and the wastewater to be poured out. This facilitates the collection and timely treatment of filtered wastewater, preventing direct discharge and environmental pollution.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] Please see Figures 1-5 As shown, this utility model is a water sample filtration device for microbial environmental testing, including a protective shell 1 and filter cups 13. Two fixing brackets 12 are fixedly connected to the inner wall of the bottom of the protective shell 1. A rack 121 is slidably connected to one side of the two fixing brackets 12. The number of filter cups 13 is set to three. Two support brackets 122 are fixedly connected to one side of each of the three filter cups 13.

A worm gear 124 is provided on one side of the two support plates 123. A gear 125 is fixedly connected to the back of the worm gear 124. The gear 125 and the worm gear 124 are rotatably connected to the corresponding side of the two support plates 123 through a shaft. The right side of the gear 125 meshes with the left side of the rack 121. The connection is as follows: a worm gear 126 is meshed with the top of the worm wheel 124; a support plate 127 is fixedly connected to the top of the two fixed frames 12; the right side of the worm gear 126 is rotatably connected to the left side of the support plate 127; a rocker arm 128 is fixedly connected to the left side of the worm gear 126; the left side of the rocker arm 128 passes through the left side of the protective shell 1 and extends to the outside; by setting the filter cup 13, specifically by rotating the rocker arm 128, the worm gear 126 rotates on the left side of the support plate 127, and the worm gear 126 drives the worm wheel 124 to rotate on the corresponding side of the two support plates 123, thereby causing the gear 125 to drive the rack 121 to slide between the two fixed frames, thereby causing the rack 121 to drive the support frame 122 and the filter cup 13 to move. In this way, the filter cup 13 is built in, and it can be taken out by rotating the rocker arm 128 when in use, which is convenient to use and improves work efficiency.

[0027] Two support frames 122 are fixedly connected to the right side of a connecting block 131, and a sliding rod 132 is fixedly connected to the bottom of the connecting block 131.

[0028] A support rod 133 is slidably connected to the outer surface of the slide rod 132, and the bottom of the support rod 133 is fixedly connected to the bottom inner wall of the protective shell 1.

[0029] A sewage tank 11 is fixedly connected inside the protective shell 1. A drawer 111 is slidably connected to the inner wall of the sewage tank 11. A handle 112 is fixedly connected to the front of the drawer 111.

[0030] A drain pipe 14 is fixedly connected to the top of the sewage tank 11, and a filter port 141 is fixedly connected to the top of the drain pipe 14. A solenoid valve 143 is installed inside the drain pipe 14. By setting up the sewage tank 11, water samples flow into the sewage tank 11 through the filter cloth and the filter port 141 from the drain pipe 14. After the water sample is filtered, the handle 112 is pulled to make the drawer 111 slide on the inner wall of the sewage tank 11, and the drawer 111 is taken out to empty the sewage. This facilitates the collection and timely treatment of filtered sewage and avoids direct discharge that pollutes the environment.

[0031] A sealing ring 142 is fixedly connected to the bottom of the filter port 141, and the bottom of the sealing ring 142 contacts the inner wall of the bottom of the filter cup 13.

[0032] The inner wall of the filter cup 13 is in contact with the outer surface of the filter port 141, and the inside of the filter cup 13 is slidably connected to the outer surface of the drain pipe 14.

[0033] A specific application of this embodiment is as follows: In use, the filter cloth is placed on top of the filter port 141, and then the rocker arm 128 is turned, which drives the worm gear 126 to rotate on the left side of the support plate 127. The worm gear 126 drives the worm wheel 124 to rotate on the corresponding side of the two support plates 123, thereby causing the gear 125 to drive the rack 121 to slide between the two fixed frames, thereby causing the rack 121 to drive the support frame 122 and the filter cup 13 to move. At this time, the inside of the filter cup 13 slides on the outer surface of the drain pipe 14, and the slide rod 132 slides on the support rod 127.
