Abstract
Description
Technical Field
[0001] This application relates to the field of water quality testing, and in particular to a water sample transfer device for water quality testing. Background Technology
[0002] When conducting water quality testing, water samples need to be taken. In the laboratory, a water sample transfer device is needed to transfer the water sample to the testing room. During the transfer process, the water sample and test tube need to be protected to prevent the test tube from breaking and causing the water sample to leak.
[0003] Patent document CN218484480U discloses a water sample transport vehicle for water quality testing, including a flatbed cart with wheels at all four corners of its lower end. A frame is fixedly connected to the top of the cart, with a handle at one end of the frame. A dividing bar is located in the middle of the top of the frame, with a sealing plate on its upper surface. The dividing bar divides the area above the frame into an isolation zone and a sewage zone. An isolation basin is located inside the isolation zone, and a sewage basin is located inside the sewage zone. Several test tube racks are evenly spaced inside the isolation basin. Both the isolation basin and the sewage basin have sliding covers on top, which are connected to the frame via sliding grooves. A sewage collection box is located below the sewage basin and on the flatbed cart. The sewage collection box is connected to both the sewage basin and the isolation basin via drain pipes. This invention can promptly clean the ground after a water sample leaks and can also absorb the moisture on the ground, preventing the water sample from remaining in the external environment for a long time and reducing the risk of laboratory contamination.
[0004] However, the aforementioned water sample transport vehicle for water quality testing cannot effectively protect the test tubes during transportation, making the test tubes prone to breakage, and it also lacks the ability to stabilize the device during unloading. Therefore, we propose a water sample transport device for water quality testing to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the inability to effectively protect test tubes during transportation, leading to easy breakage of test tubes, and the inability to stabilize the device during unloading. Therefore, this invention proposes a water sample transfer device for water quality testing.
[0006] The water sample transfer device for water quality testing provided in this application adopts the following technical solution:

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0029] Example 1
[0030] Reference Figure 1-Figure 3 A water sample transfer device for water quality testing, comprising:
[0031] Base 1;
[0032] Four casters 2 are rotatably connected to the bottom of the base 1, and the top of the base 1 is fixedly connected to the box 3;
[0033] Two rotating shafts 4 are rotatably connected to the top of both sides of the box body 3, and box doors 5 are fixedly connected to the two rotating shafts 4 respectively;
[0034] Two handles 6 are fixedly connected to the top of the box door 5, and a push handle 7 is fixedly connected to one side of the box body 3;
[0035] The electric motor 8 is fixedly connected to the inner wall of one side of the housing 3;
[0036] The transmission component is fixedly connected to the output shaft of the motor 8.
[0037] Specifically, the transmission assembly includes a first transmission shaft 9 fixedly connected to the output shaft of the motor 8, and a second transmission shaft 10 rotatably connected to the inner wall of the housing 3. The first transmission shaft 9 is rotatably connected to one side of the inner wall of the housing 3.
[0038] Specifically, two pulleys 11 are fixedly connected to the first drive shaft 9 and the second drive shaft 10 respectively, and the two pulleys 11 are connected to the same belt 12.
[0039] Specifically, two worm gears 13 are fixedly connected to the first drive shaft 9 and the second drive shaft 10 respectively, and the two worm gears 13 are respectively engaged with two worm wheels 14.
[0040] Specifically, the two worm gears 14 are fixedly connected to the same third drive shaft 15, and the third drive shaft 15 is rotatably connected to the inner wall of the housing 3.
[0041] Specifically, two gears 16 are fixedly connected to the third drive shaft 15, and the two gears 16 respectively mesh with two racks 17.
[0042] Specifically, two connecting rods 18 are fixedly connected to one side of each of the two racks 17, and the bottom of the two connecting rods 18 is fixedly connected to the same fixing plate, and the top of the two connecting rods 18 is fixedly connected to the same fixing rod 19.
[0043] Specifically, a sliding plate 20 is fixedly connected to the top of the fixed rod 19. The sliding plate 20 is slidably connected to the inner wall of the box 3. Three protective groove plates 21 are provided on the sliding plate 20. A support plate 22 is fixedly connected to the inner wall of the box 3. A placement groove is provided on the support plate 22. A cover plate 23 is fitted on the placement groove.
[0044] Specifically, the protective groove plate 21 is made of U-shaped silicone material, with a groove depth of 15mm and longitudinal anti-slip texture on the inner wall; the bottom of the cover plate 23 is fitted with an annular rubber pressure ring with an inner diameter of 14.5mm (suitable for standard test tubes); the side wall of the placement groove is pasted with an EPE foamed polyethylene layer with a thickness of 10mm and a compression set of ≤8%.
[0045] The implementation principle of a water sample transfer device for water quality testing according to an embodiment of this application is as follows: First, open the two boxes 5 using the two handles 6 respectively. Then, place the sampled test tube into the placement slot and place the cover plate 23 on the support plate 22 to fix the top of the test tube and prevent it from shaking. Then, start the motor 8. The motor 8 drives the first transmission shaft 9 to rotate, which in turn drives the pulley 11 to rotate. The pulley 11 drives another pulley 11 to rotate via the belt 12. The pulley 11 drives the second transmission shaft 10 to rotate. The first and second transmission shafts 9 and 10 respectively drive two worm gears 13 to rotate, which in turn drive two worm wheels 14 to rotate. The two worm wheels 14 drive the same third transmission shaft 15 to rotate, which in turn drives two gears 16 to rotate. The two gears 16 respectively drive two racks 17 to move. The device is activated by moving two racks 17, which in turn move two connecting rods 18. These connecting rods 18 then move a fixed plate, causing the fixed plate to lift off the ground and no longer maintain the stability of the device. Simultaneously, the two connecting rods 18 move a fixed rod 19, which in turn moves a sliding plate 20. The sliding plate 20 then moves three protective groove plates 21, which engage with the bottom of the test tube to prevent it from breaking due to impact, thus protecting the test tube. Afterward, the two doors 5 are closed, and the device is moved by pushing the handle 7. When it is necessary to remove the test tube, the motor 8 drives the fixed plate to the ground. The fixed plate contacts the ground and fixes the device, preventing it from moving. At the same time, the sliding plate 20 moves the three protective groove plates 21, releasing the protection of the test tube. The cover plate 23 is then removed, and the test tube is taken out.
[0046] Example 2
[0047] The difference between this embodiment and embodiment one is that a push rod motor is fixedly connected to the inner wall of the box 3, and a connecting plate is fixedly connected to the output shaft of the push rod motor. The connecting plate cooperates with the placement slot, and a through slot is opened on the connecting plate. The through slot cooperates with three protective slot plates 21. When the test tube is taken out, the push rod motor is started, the push rod motor drives the connecting plate to move, and the connecting plate drives the test tube in the placement slot to move, which makes it convenient to take out the test tube.
[0048] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
