[0027] A water quality testing bench includes a testing bench 1. Support legs 2 are fixedly connected to the four corners of the lower end of the testing bench 1. A faucet 4 is fixedly connected to the upper end of the testing bench 1. An auxiliary device 3 is fixedly connected to the upper left part of the testing bench 1. A water receiving trough 5 is opened in the middle of the upper end of the testing bench 1. A collection device 7 is snapped into the water receiving trough 5. Side blocks 6 are fixedly connected to the upper left and upper right parts of the testing bench 1. Locking grooves 8 are opened on the opposite sides of the side blocks 6. The two side blocks 6 are located on the left and right sides of the water receiving trough 5, respectively.

[0028] In this embodiment, the auxiliary device 3 includes a base 31. A groove 32 is formed at the upper end of the base 31. A sliding plate 311 is slidably connected within the groove 32. A handle groove 34 is formed on the upper right side of the sliding plate 311. A cleaning component 33 is fixedly connected to the upper right side of the sliding plate 311. A lamp tube groove 37 is formed on the upper left side of the sliding plate 311. Multiple electric heating rods 38 are arranged on the left and right walls of the lamp tube groove 37. A mesh plate 39 is fixedly connected to the upper left side of the sliding plate 311. Multiple test tube racks 310 are fixedly connected to the upper end of the perforated plate 39. A battery module 35 is fixedly connected to the left end of the sliding plate 311. A switch 36 is provided on the left end of the battery module 35. The base 31 is fixedly connected to the upper left part of the inspection table 1. The cleaning component 33 includes a sleeve 331. A screw 334 is movably connected to the lower wall of the sliding plate 311 through a bearing. A sliding disc 332 is threadedly connected to the upper part of the outer surface of the screw 334. A first spring is fixedly connected to the lower end of the sliding disc 332. 335, a brush rod 336 is fixedly connected to the upper end of the screw 334, and multiple brush strips 337 are fixedly connected to the outer surface of the brush rod 336. A sleeve 331 is fixedly connected to the upper right side of the sliding plate 311. A groove 32 is opened along the length of the base 31. The width of the groove 32 is adapted to the bottom width of the sliding plate 311, and the sliding plate 311 slides linearly within the groove 32. Multiple test tube racks 310 are distributed horizontally at equal intervals. The battery module 35 is connected to the switch 36 via built-in wiring. A series of electric heating rods 38 are connected in series. A switch 36 controls the circuit of the electric heating rods 38. A screw 334 is rotatably mounted on the center of the lower cylinder wall of the sleeve 331 via a bearing. A sliding disc 332 is threaded onto the upper part of the outer surface of the screw 334 and can move up and down along the screw 334. A first spring 335 connects the lower end of the sliding disc 332 to the bottom of the sleeve 331. A brush rod 336 is fixed to the upper end of the screw 334. Multiple brush strips 337 are evenly distributed circumferentially along the outer surface of the brush rod 336.

[0029] Through the above scheme: the base 31 of the auxiliary device 3 is fixed on the inspection table 1, the sliding plate 311 can slide linearly through the sliding groove 32, and the user can easily pull the sliding plate 311 to adjust its position through the handle groove 34. When in use, the test tube is placed on the test tube rack 310 of the mesh plate 39. When the test tube needs to be cleaned, it is inverted on the brush strip 337 of the cleaning component 33 and pressed. The sliding disc 332 moves down along the screw 334 to compress the first spring 335. Due to the threaded engagement, the screw 334 drives the brush rod 336 to rotate, realizing the rotational brushing of the inner wall of the test tube. After releasing the test tube, the first spring 335 returns to its original position, causing the sliding disc 332 to move up, the screw 334 to reverse, and the brush strip 337 to rotate. A second reverse scrubbing enhances the cleaning effect. After cleaning, the test tubes can be powered by the battery module 35 via switch 36, which in turn powers the electric heating rod 38. The heat from the lamp tube slot 37 is then used for drying. This design allows for flexible adjustment of the operating position through a sliding base 31, a groove 32, and a sliding plate 311. The bidirectional rotating brush assembly screw 334, brush rod 336, and brush strip 337 improve cleaning efficiency. The electric heating drying function of the battery module 35, switch 36, and electric heating rod 38 shortens the drying time of the test tubes. The horizontally equidistant test tube rack 310 facilitates the classification and placement of different samples. The overall structure is compact and functionally integrated, significantly improving the operational convenience and experimental efficiency of water quality testing.

[0030] In this embodiment, the collecting device 7 includes a partition plate 71. A circular groove 74 is opened in the middle of the upper end of the partition plate 71. A collecting cone 72 is engaged in the circular groove 74. A filter screen 73 is fixedly connected to the surface of the collecting cone 72. Locking support blocks 75 are fixedly connected to the upper left and upper right parts of the partition plate 71. A second spring 76 is provided on the inner wall of the locking support block 75. Locking blocks 77 are provided on the front left and rear left parts of the locking support block 75. The partition plate 71 is engaged in the circular groove 74. The locking blocks 77 are symmetrically arranged on the front left and rear left parts of the locking support block 75, and the locking blocks 77 are used to cooperate with the locking groove 8 of the side block 6.

[0031] Through the above scheme: When the collecting device 7 is in use, the partition plate 71 is snapped into the water tank 5 of the inspection table 1, and the locking block 77 on the locking support block 75 is tightly engaged with the locking groove 8 of the side block 6 under the action of the second spring 76, realizing the quick installation and stable fixation of the collecting device 7. The collecting cone 72 is snapped into the circular groove 74 of the partition plate 71. When water flows into the water tank 5 through the faucet 4 on the inspection table 1, the filter screen 73 on the surface of the collecting cone 72 intercepts and filters impurities in the water flow, preventing impurities from entering the pipe and causing blockage. The filtered water flow is then collected by the collecting cone 72. 2. Collection: If cleaning or replacement of the collection device 7 is required, simply press the locking block 77 to overcome the elasticity of the second spring 76 and disengage from the locking groove 8. The partition plate 71 and the collection cone 72 can then be easily removed. The collection device 7 achieves convenient installation and disassembly through a clever locking structure: locking support block 75, second spring 76, locking block 77, side block 6, and locking groove 8. The filter screen 73 effectively ensures unobstructed pipe flow. The design of the collection cone 72 facilitates water sample collection, improves the convenience and practicality of the water quality testing bench, reduces maintenance costs, and extends the service life of the equipment.

[0032] It should be noted that this utility model is a water quality testing bench. During use, the support feet 2 at the four corners of the lower end of the testing bench 1 provide stable support. When the test tubes need to be operated, the auxiliary device 3 located on the upper left side of the testing bench 1 comes into play. The sliding plate 311 can slide within the groove 32 of the base 31, facilitating position adjustment. The test tubes are placed on multiple test tube racks 310 on the mesh plate 39. If cleaning is required, the cleaning component 33 can be used. The test tube is inverted, allowing the brush strip 337 on the brush rod 336 to enter the test tube. Pressing downwards causes the test tube to slide against the sliding disc 332 within the sleeve 331. Because the screw 334 and the sliding disc 332 are threadedly connected, the sliding disc 332 moves the screw 334 downwards, causing the screw 334 to rotate within the bearing on the lower wall of the sleeve 331. This causes the brush rod 336 to rotate, rotating the brush strip 337 to clean the inside of the test tube. The test tube is then lifted. After the tube is cleaned, the sliding disc 332 slides upward under the action of the first spring 335, and the screw 334 reverses the brush rod 336 to clean the test tube again, achieving a cleaner cleaning effect. After cleaning, if the test tube needs to be dried, it can be powered by the battery module 35 and the multiple electric heating rods 38 in the lamp tube slot 37 can be controlled by the switch 36 to heat and dry the test tube. During the water quality test, the water flowing from the faucet 4 passes through the water receiving tank 5 in the middle of the test bench 1. The collection device 7, which is locked in the water receiving tank 5, plays its role. The collecting cone 72 collects the water flow, and the filter screen 73 on the surface filters the water quality to prevent impurities from clogging the pipe. The partition plate 71 cooperates with the locking block 77 on the locking support block 75 and the locking groove 8 on the side block 6 to facilitate installation and disassembly, and to facilitate cleaning and replacement of the collection device 7. The entire test bench realizes the functions of pressing and brushing, heating and drying, easy installation and water filtration.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
