Biochemical oxygen demand (BOD) is a biological term, which refers to a comprehensive indicator of the content of oxygen-demanding pollutants such as organic matter in water samples, indicating the total amount of dissolved oxygen consumed in the water when the organic matter in the water is oxidized and decomposed by the biochemical action of microorganisms to make it inorganic or gaseous.

[0003] In order to further understand the BOD sample bottle cleaning device in the prior art, after searching, the Chinese patent with announcement number: CN220111866U discloses a sample bottle cleaning device for water resource detection, including a cleaning body, a cleaning unit, a sample bottle fixing unit, and a water spray drying unit; the cleaning body: the four corners of the lower side surface are respectively fixedly connected to the supporting legs, the front side surface of the cleaning body is provided with a rectangular groove, and the upper end surface of the rectangular groove is provided with a water spray drying unit, the front side surface of the cleaning body is located at the lower side of the rectangular groove. A wastewater collecting groove is provided, and the bottom end surface of the wastewater collecting groove is fixedly connected to the wastewater collecting pool, one side of the rectangular groove on the cleaning body is slidably connected to a fixed door panel 2, and the front side surface of the fixed door panel 2 is fixedly connected to an armrest, the bottom end surface of the rectangular groove is provided with a cleaning unit, and the bottom end surface of the cleaning body located in the rectangular groove is located at a card in the cleaning unit A plurality of equally spaced rectangular through holes are respectively provided at the positions of the edges of the connecting circular plate, and all the rectangular through holes extend into the corresponding wastewater collection tanks respectively. A sample bottle fixing unit is provided on the lower surface of the clamping circular plate in the cleaning unit; the cleaning unit comprises a clamping circular plate, a stabilizing bearing, a hydraulic cylinder, a cleaning brush, a fixing block and a buffer telescopic column. A circular hole is provided on the inner bottom surface of the rectangular groove on the cleaning body, and the circular hole extends into the wastewater collection tank. The circular hole is rotatably connected to the clamping circular plate through a stabilizing bearing. The upper surface of the clamping circular plate is fixedly connected to one end of the hydraulic cylinder, and the other end of the hydraulic cylinder is fixedly connected to the fixing block.

[0004] After exploration and analysis, it was found that the patent has the following shortcomings in actual use: although the residual water is dried after the sample bottle is cleaned in the patent, a large amount of cleaning water will remain in the sample bottle after the cleaning is completed. Before the subsequent drying operation, the operator must either take the sample bottle out of the device, pour out the cleaning water, and then put it back into the device for drying, or directly dry the large amount of remaining cleaning water. Both methods will reduce the cleaning efficiency of the sample bottle and are not conducive to the rapid cleaning of the sample bottle. Utility Model Content

[0028] The following is combined with Figure 1-6 The utility model is further described.

[0029] In order to solve the problems existing in the background technology, the present application proposes the following technical scheme: it includes a cleaning box 1, a fixed block 2 is fixedly connected to the top of the cleaning box 1, a first electric slide rail 3 is fixedly installed in the fixed block 2, a first electric slider 4 is slidably installed in the first electric slide rail 3, a connecting plate 5 is fixedly connected to the first electric slider 4, a placement plate 6 is fixedly connected to one side of the connecting plate 5, a placement hole 7 is opened on the placement plate 6, a buffer plate 8 is fixedly installed on the bottom of the fixed block 2, a fixing hole 9 is opened at the bottom of the buffer plate 8, and a cleaning mechanism is arranged below the placement plate 6.

[0030] Place the BOD sample bottle upside down in the placement hole 7 of the placement plate 6, start the first electric slider 4, and the first electric slider 4 drives the connecting plate 5, the placement plate 6 and the BOD sample bottle placed on the placement plate 6 to move upward, so that the bottom of the BOD sample bottle is clamped in the fixing hole 9, thereby fixing the BOD sample bottle between the fixing block 2 and the placement plate 6. After the cleaning mechanism rinses the inner wall of the BOD sample bottle, since the BOD sample bottle is placed upside down, a large amount of cleaning water will not remain in the BOD sample bottle, and there is only a thin water film inside the BOD sample bottle, which is convenient for subsequent drying operations, thereby effectively improving the cleaning efficiency of the BOD sample bottle.

[0031] The placement plate 6 and the buffer plate 8 are both made of rubber material, which can fix the BOD sample bottle without causing damage to it.

[0032] It is further explained that the cleaning mechanism includes a water tank 28 fixedly installed at the bottom of the cleaning box 1, an electric push rod 10 fixedly installed at the bottom of the cleaning box 1, and a movable plate 11 fixedly connected to the top of the electric push rod 10, a mounting ring 12 fixedly connected to the movable plate 11, and a nozzle 13 fixedly installed on the mounting ring 12.

[0033] The nozzle 13 is connected to the water tank 28 by a telescopic hose, and a water pump is provided in the water tank 28 (the telescopic hose and the water pump are not shown in the attached drawings). After the BOD sample bottle is fixed on the placement plate 6, the electric push rod 10 drives the movable plate 11 to move upward, so that the nozzle 13 extends into the BOD sample bottle, and the water pump transports clean water to the nozzle 13 to spray out and clean the inner wall of the BOD sample bottle.

[0034] It is further explained that a rotating rod 14 is rotatably installed in the movable plate 11, and three groups of limiting grooves 22 are opened at the upper end of the rotating rod 14. Two groups of fixed seats 19 are slidably installed in the three groups of limiting grooves 22. Connecting rods 20 are rotatably installed on the two groups of fixed seats 19, and a cleaning block 21 is rotatably installed on the end of the connecting rod 20 away from the fixed seat 19.

[0035] The moving plate 11 drives the rotating rod 14 and the cleaning block 21 to move upward, the rotating rod 14 extends into the BOD sample bottle, and the cleaning block 21 cooperates with the water sprayed by the nozzle 13 to clean the inner wall of the BOD sample bottle, further improving the cleaning effect.

[0036] It is further explained that a movable cavity 15 is opened in the rotating rod 14, and a motor 16 is fixedly installed inside the rotating rod 14. A bidirectional threaded rod 17 is fixedly connected to the driving shaft of the motor 16. The bidirectional threaded rod 17 is rotatably installed in the movable cavity 15. Two groups of moving blocks 18 are threadedly sleeved on the bidirectional threaded rod 17, and the two groups of moving blocks 18 are fixedly connected to the fixed seats 19 respectively.

[0037] The motor 16 drives the bidirectional threaded rod 17 to rotate, and the bidirectional threaded rod 17 pushes the two groups of moving blocks 18 to move relatively away or relatively close. When the two groups of moving blocks 18 are relatively far away, the two groups of fixed seats 19 in the limiting groove 22 are relatively far away, and the fixed seat 19 pulls the cleaning block 21 to move toward the rotating rod 14, shortening the distance between the cleaning block 21 and the rotating rod 14, making it easy to extend the rotating rod 14 and the cleaning block 21 into the BOD sample bottle; when the two groups of moving blocks 18 are relatively close, the two groups of fixed seats 19 in the limiting groove 22 are relatively close, and the fixed seat 19 pushes the cleaning block 21 to move away from the rotating rod 14, increasing the distance between the cleaning block 21 and the rotating rod 14, making it easy for the cleaning block 21 to contact the inner wall of the BOD sample bottle of different specifications, thereby realizing the cleaning of the BOD sample bottles of different specifications, and improving the practicality of the device.

[0038] It is further explained that a second electric slide rail 24 is fixedly installed in the movable plate 11, a second electric slider 25 is slidably installed in the second electric slide rail 24, a tooth plate 26 is fixedly connected to the bottom of the second electric slider 25, a gear 23 is meshed with one side of the tooth plate 26, and the upper end surface of the gear 23 is fixedly connected to the bottom end of the rotating rod 14.

[0039] After the cleaning block 21 contacts the inner wall of the BOD sample bottle, the second electric slider 25 is started, and the second electric slider 25 slides in the second electric slide rail 24, and the second electric slide rail 24 drives the toothed plate 26 to move, and the toothed plate 26 drives the gear 23 to rotate, and the gear 23 drives the rotating rod 14 to rotate, and the rotating rod 14 drives the cleaning block 21 to rotate in the BOD sample bottle to clean the inner wall of the BOD sample bottle. The rotating cleaning block 21 cooperates with the water sprayed from the nozzle 13 to completely clean the inner wall of the BOD sample bottle.

[0040] It is further explained that three groups of heating blocks 27 are fixedly mounted on the movable plate 11. After the BOD sample bottle is cleaned, the heating block 27 works to dry the thin water film remaining on the inner wall of the BOD sample bottle to prevent the residual moisture from affecting the subsequent use of the BOD sample bottle.

[0041] The specific operation is as follows: place the BOD sample bottle upside down in the placement hole 7 of the placement plate 6, start the first electric slider 4, the first electric slider 4 drives the connecting plate 5, the placement plate 6 and the BOD sample bottle placed on the placement plate 6 to move upward, so that the bottom of the BOD sample bottle is clamped in the fixing hole 9, start the electric push rod 10, the electric push rod 10 drives the moving plate 11 to move upward, so that the nozzle 13 extends into the BOD sample bottle, and the water pump delivers clean water to the nozzle 13 to spray it to clean the inner wall of the BOD sample bottle. At the same time, the motor 16 drives the bidirectional screw The threaded rod 17 rotates, and the bidirectional threaded rod 17 pushes the two groups of moving blocks 18 to move closer, and the connecting rod 20 pushes the cleaning block 21 to approach and contact the inner wall of the BOD sample bottle. After the cleaning block 21 contacts the inner wall of the BOD sample bottle, the second electric slider 25 is started, and the second electric slider 25 slides in the second electric slide rail 24. The second electric slide rail 24 drives the tooth plate 26 to move, and the tooth plate 26 drives the gear 23 to rotate. The gear 23 drives the rotating rod 14 to rotate, and the rotating rod 14 drives the cleaning block 21 to rotate in the BOD sample bottle to clean the inner wall of the BOD sample bottle.
