Description

Technical Field

[0001] The utility model relates to the field of fluorescent cap protection devices, in particular to a fluorescent cap protection device for a dissolved oxygen probe. Background Art

[0002] Dissolved oxygen probes measure the amount of oxygen dissolved in aqueous solutions. Oxygen is dissolved in water by the surrounding air, air movement, and photosynthesis. They can be used to monitor processes where oxygen levels can affect reaction rates, process efficiency, or the environment: aquaculture, biological reactions, environmental testing (lakes, streams, oceans), and wastewater treatment.

[0003] The dissolved oxygen probe uses a chemical diaphragm for measurement. In some environments, the probe needs to be placed in water for a long time for regular testing. However, there is no protective device at the fluorescent head of the detection membrane. When the water quality environment is poor, it is difficult to effectively protect the probe. It is easily blocked by floating objects in the water, affecting its service life. In addition, it is difficult for workers to clean it during use, which may affect the detection effect and is relatively inconvenient. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide a fluorescent cap protection device for a dissolved oxygen probe to solve the technical problems mentioned in the above background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a dissolved oxygen probe fluorescent cap protection device, comprising a dissolved oxygen probe body, a mounting shell fixedly mounted on one end of the dissolved oxygen probe body, and a protective cover detachably mounted on one end of the mounting shell, a connecting rod fixedly mounted on one end of the protective cover, and a buffer plate movably mounted on one end of the connecting rod, a second spring provided on the outer sleeve of the connecting rod, and the buffer plate and the protective cover are connected via the second spring, an extension block fixedly mounted on one end of the protective cover, a fixed rod fixedly mounted on the inside of the extension block, an inner rod movably mounted on the inside of the fixed rod, and a cleaning component for cleaning the end surface of the protective cover fixedly mounted on one end of the inner rod.

[0006] By adopting the above technical solution, by providing components such as a fixing rod, a convex plate, a groove, an inner rod and a rotating plate, when workers use this equipment to test water quality, they only need to control the fixing rod to place the dissolved oxygen probe body and the protective cover into the liquid to be tested. The lowering height of the dissolved oxygen probe body can be controlled by the scale line, which is convenient for workers to observe. The block inside the protective cover can ensure the stable connection between the mounting shell and the mounting shell during use. At the same time, the groove and the convex plate can ensure sealing to prevent water from entering the interior of the protective cover, effectively protecting the dissolved oxygen probe body. When the end face of the protective cover needs to be cleaned, only the inner rod needs to be rotated to drive the rotating plate to rotate. The cleaning block is subjected to the elastic force of the third spring to ensure that it can effectively fit with the end face of the protective cover to ensure the cleaning effect. Compared with traditional dissolved oxygen probes, this equipment can be cleaned during use. At the same time, the protective cover, mounting shell and buffer plate and other components can effectively protect the dissolved oxygen probe body, thereby increasing its overall service life and ensuring its detection effect.

[0007] The utility model is further configured as follows: the cleaning assembly includes a rotating plate, a movable rod, a cleaning block and a third spring; the rotating plate is fixedly installed on one end of the inner rod, and the movable rod is movably installed inside the rotating plate; the cleaning block is fixedly installed on one end of the movable rod, and the cleaning block is composed of a mounting plate and a nano sponge.

[0008] By adopting the above technical solution, the fixedly installed rotating plate drives the rotating plate to rotate when the inner rod rotates, and the movably installed movable rod drives the cleaning block to move inside the rotating plate. The cleaning block consists of a mounting plate and a nano sponge. The mounting plate can provide support and fixation in position, and the nano sponge can better clean one side end face of the protective cover, effectively ensuring the cleaning effect.

[0009] The utility model is further configured such that a through slot for the cleaning block to move is provided inside the rotating plate, and a third spring connected to the cleaning block and the rotating plate is sleeved on the outside of the movable rod.

[0010] By adopting the above technical solution, the through groove provides a certain space for the cleaning block to move inside the rotating plate, and the third spring will continuously apply elastic force to the cleaning block, so that when the cleaning block rotates, it will fit with the end face of the protective cover, ensuring its cleaning effect on the protective cover.

[0011] The utility model is further configured such that a convex plate is fixedly mounted on one end of the protective cover, and a groove matching the convex plate is provided inside the mounting shell, a first spring is fixedly mounted on the inside of the convex plate, and a clamping block is fixedly mounted on one end of the first spring.

[0012] By adopting the above technical solution, the convex plate cooperates with the driving groove opened inside the mounting shell to initially restrict the protective cover and ensure the sealing effect. The first spring will continuously apply elastic force to the card block to ensure that it can normally enter the card slot, fix and restrict it.

[0013] The present invention is further configured such that a movable groove for the card block to move is provided inside the convex plate, and a card slot matching the card block is provided inside the mounting shell.

[0014] By adopting the above technical solution, the movable groove provides a certain space for the card block to move inside the convex plate, and at the same time imposes certain restrictions on its moving direction and distance to prevent it from being separated from the convex plate under the action of the first spring, thereby affecting normal use. The card slot and the card block are matched, so that when the worker puts the convex plate into the groove, he rotates the protective cover as a whole. After rotating to a certain angle, the card block enters the inside of the card slot under the action of the first spring, thereby completing the installation between the protective cover and the mounting shell.

[0015] The utility model is further configured such that scale lines are engraved on the outside of the fixed rod, a handle is fixedly mounted on one end of the inner rod, and a limit plate is fixedly mounted on one end of the inner rod.

[0016] By adopting the above technical solution, the scale line can enable workers to know more clearly the position of the dissolved oxygen probe body inside the liquid, the handle can facilitate workers to more conveniently control the rotation of the inner rod, and the limit plate can control the position of the inner rod on the fixed rod to prevent it from being separated from the fixed rod, thereby ensuring the reliability of the equipment.

[0017] In summary, the present invention has the following beneficial effects:

[0018] The utility model is provided with components such as a fixing rod, a convex plate, a groove, an inner rod and a rotating plate, so that when a worker uses the device to detect water quality, he only needs to control the fixing rod to place the dissolved oxygen probe body and the protective cover into the liquid to be detected, and the lowering height of the dissolved oxygen probe body can be controlled by the scale line, which is convenient for the worker to observe. The block inside the protective cover can ensure that the connection between the mounting shell and the mounting shell is stable during use. At the same time, the groove and the convex plate can ensure sealing to prevent water from entering the interior of the protective cover, effectively protecting the dissolved oxygen probe body. When the end face of the protective cover needs to be cleaned, the rotating plate can be driven to rotate by rotating the inner rod. The cleaning block is subjected to the elastic force of the third spring to ensure that it can effectively fit with the end face of the protective cover, ensuring the cleaning effect. Compared with the traditional dissolved oxygen probe, the present device can be cleaned during use. At the same time, the protective cover, the mounting shell and the buffer plate and other components can effectively protect the dissolved oxygen probe body, thereby improving its overall service life and ensuring its detection effect.

When using this equipment, workers only need to put the convex plate 4 fixedly installed at one end of the protective cover 3 into the mounting shell 2, the protective cover 3 is rotated as a whole so that the card block 8 enters the card slot 10, completing the assembly and sealing of the protective cover 3 and the mounting shell 2, effectively protecting the dissolved oxygen probe body 1. The worker picks up the fixing rod 14 and drives the dissolved oxygen probe body 1 to place it into the liquid to be tested. If it is necessary to clean one side of the end face of the protective cover 3, it is only necessary to rotate the handle 16 so that the inner rod 15 drives the rotating plate 17 at one end to rotate. The cleaning block 19 inside it is continuously subjected to the elastic force applied by the third spring 20 to ensure that the cleaning block 19 is in contact with one side of the end face of the protective cover 3, completing the cleaning, which can effectively ensure the cleanliness of the end face of the protective cover 3, prevent foreign matter from corroding the protective cover 3, and effectively ensure the accuracy of its detection results.

[0028] See also Figure 1 - Figure 4 The cleaning assembly includes a rotating plate 17, a movable rod 18, a cleaning block 19 and a third spring 20. One end of the inner rod 15 is fixedly mounted with the rotating plate 17, and the movable rod 18 is movably mounted inside the rotating plate 17. One end of the movable rod 18 is fixedly mounted with a cleaning block 19, and the cleaning block 19 is composed of a mounting plate and a nano sponge. The fixedly mounted rotating plate 17 enables the inner rod 15 to drive the rotating plate 17 to rotate together when it rotates, and the movably mounted movable rod 18 enables it to drive the cleaning block 19 to move inside the rotating plate 17. The cleaning block 19 is composed of a mounting plate and a nano sponge. The mounting plate can provide support and fixation in position.

[0029] See also Figure 3 - Figure 4 A through slot is provided inside the rotating plate 17 for the cleaning block 19 to move, and a third spring 20 is provided on the outside of the movable rod 18 to connect the cleaning block 19 and the rotating plate 17. The through slot provides a certain space for the cleaning block 19 to move inside the rotating plate 17. The third spring 20 will continuously apply elastic force to the cleaning block 19, so that when the cleaning block 19 rotates, it will fit with the end surface of the protective cover 3, thereby ensuring its cleaning effect on the protective cover 3.

[0030] See also Figure 2 - Figure 5 A convex plate 4 is fixedly installed at one end of the protective sleeve 3, and a groove 6 matching the convex plate 4 is opened inside the mounting shell 2. A first spring 7 is fixedly installed inside the convex plate 4, and a card block 8 is fixedly installed at one end of the first spring 7. The convex plate 4 cooperates with the driving groove 6 opened inside the mounting shell 2 to perform preliminary restrictions on the protective sleeve 3 to ensure the sealing effect. The first spring 7 will continuously apply elastic force to the card block 8 to ensure that it can normally enter the card slot 10 to fix and restrict it.

[0031] See also Figure 2 - Figure 5 The inside of the convex plate 4 is provided with a movable groove 9 for the card block 8 to move, and the inside of the mounting shell 2 is provided with a card slot 10 that matches the card block 8. The movable groove 9 provides a certain space for the card block 8 to move inside the convex plate 4, and at the same time imposes certain restrictions on its moving direction and distance to prevent it from being separated from the convex plate 4 under the action of the first spring 7, affecting normal use. The card slot 10 matches the card block 8, so that when the worker puts the convex plate 4 into the groove 6, he rotates the protective cover 3 as a whole. After rotating to a certain angle, the card block 8 enters the inside of the card slot 10 under the action of the first spring 7, thereby completing the installation between the protective cover 3 and the mounting shell 2.

[0032] See also Figure 1 - Figure 3 The outside of the fixed rod 14 is engraved with scale lines 21, one end of the inner rod 15 is fixedly mounted with a handle 16, and one end of the inner rod 15 is fixedly mounted with a limit plate 22.

[0033] The working principle of the present utility model is as follows: when using the device, the worker only needs to put the convex plate 4 fixedly installed at one end of the protective cover 3 into the groove 6 inside the mounting shell 2, rotate the protective cover 3 as a whole, so that the card block 8 enters the card slot 10, complete the assembly and sealing of the protective cover 3 and the mounting shell 2, and effectively protect the dissolved oxygen probe body 1. The worker picks up the fixing rod 14 and drives the dissolved oxygen probe body 1 to put it into the liquid with detection. The mounting shell 2 carved on the end face of the fixing rod 14 can control its depth in the liquid. After moving to a certain position, the worker can fix the fixing rod 14 for detection. If one side end face of the protective cover 3 needs to be cleaned during the detection process, it is only necessary to turn the handle 16 so that the inner rod 15 drives the inner rod 15 to move ... The rotating plate 17 at one end rotates. After the rotating plate 17 rotates to a certain angle, the cleaning block 19 inside it is continuously subjected to the elastic force applied by the third spring 20 to ensure that the cleaning block 19 contacts one end face of the protective cover 3 to complete its cleaning, which can effectively ensure the cleanliness of the end face of the protective cover 3, prevent debris from corroding the protective cover 3, and effectively ensure the accuracy of its detection results. After the detection is completed, the fixing rod 14 can be pulled out to remove the dissolved oxygen probe body 1. The buffer plate 12, connecting rod 11 and second spring 13 and other components can effectively protect the protective cover 3 and the dissolved oxygen probe body 1 to prevent them from being damaged or squeezed during the process of taking and placing, thereby increasing its service life.
