[0033] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] In addition, the expression “including” an element is an “open” expression, which simply means that corresponding components exist and should not be interpreted as excluding additional components.

[0036] In order to achieve the purpose of the present invention, in some embodiments of the pH probe buoyancy device, as Figure 1-2 As shown, the pH probe buoyancy device includes: a monitoring tank 1, a guide pipe 2, a float 3 and a pH probe 4. The monitoring tank 1 carries the liquid to be monitored and can be connected to the raw water tank through a pipeline with a valve installed on the pipeline.

[0037] The guide tube 2 is placed in the monitoring tank 1 and has a plurality of liquid inlet holes 21 distributed on the guide tube 2. The liquid inlet holes 21 are used to introduce the liquid in the monitoring tank 1 into the guide tube 2. The guide tube 2 can be, but is not limited to, detachably fixedly mounted on the monitoring tank 1.

[0038] The float 3 is placed in the guide tube 2. The float 3 can rise and fall under the action of the liquid in the guide tube 2, and the guide tube 2 is used to guide the rising and falling of the float 3. There is a small gap between the outer wall of the float 3 and the inner wall of the guide tube 2, which will not hinder the rising and falling of the float 3, but also gives the float 3 a certain limit.

[0039] The pH probe 4 is fixedly mounted on the float 3 . The pH probe 4 can rise and fall along with the float 3 under the action of the buoyancy of the liquid. The pH probe 4 is electrically connected to the display 6 via a wire 5 .

[0040] The outer wall profile of the buoy 3 matches the inner wall profile of the guide tube 2 , and both the buoy 3 and the guide tube 2 are cylindrical structures.

[0041] In this utility model, a float 3 is placed within a guide tube 2, and a pH probe 4 is embedded within the float 3. Liquid flows into the guide tube 2 through the liquid inlet through-hole 21. The liquid level in the guide tube 2 is aligned with the liquid level in the monitoring tank 1. The float 3 changes with the floating liquid level. The pH probe 4 is fixed within the float 3 and also changes with the floating liquid level. The pH probe 4 is immersed in the liquid to monitor the pH of the liquid.

[0042] The pH probe 4 and the buoy 3 can be pre-assembled together to form a floating monitoring assembly, and then placed into the guide tube 2.

[0043] In order to further optimize the implementation effect of the present invention, in some other embodiments, the remaining characteristic technologies are the same, except that the top of the float 3 is a closed end with an inlet hole, and the bottom is an open end.

[0044] With the above-mentioned structure of the float 3 , the liquid can quickly fill the inner cavity of the float 3 .

[0045] Furthermore, based on the above embodiment, the pH probe 4 is detachably fixedly connected to the buoy 3 via a fixing assembly.

[0046] In some embodiments, the fixing component is a block ring 7 installed on the top of the float 3 and the outer periphery of the introduction hole. The block ring 7 is used to clamp the pH probe 4.

[0047] The stopper ring 7 can prevent the pH probe 4 from slipping.

[0048] In other embodiments, Figure 3-4 As shown, the fixing assembly is two semicircular connecting hoops 81;

[0049] Adjacent connecting hoops 81 are connected to each other through a connecting piece to form a clamping ring 82 . The inner wall profile of the clamping ring 82 matches the outer wall profile of the installation position of the pH probe 4 .

[0050] A plurality of through holes are distributed on the connecting clamp 81 , and the connecting clamp 81 is fixedly connected to the buoy 3 via a connecting piece.

[0051] The pH probe 4 is mounted on the buoy 3 using the connecting clamp 81 for a more secure installation.

[0052] In order to further optimize the implementation effect of the present invention, in some other embodiments, the remaining characteristic technologies are the same, except that, Figure 5-6 As shown, an elastic ring 9 is installed on the inner wall surface of the float 3, and the pH probe 4 extends into the central through hole 91 of the elastic ring 9, and the aperture of the central through hole 91 of the elastic ring 9 gradually decreases from top to bottom.

[0053] The elastic ring 9 is deformable. When the pH probe 4 is inserted downwardly into the central through hole 91 of the elastic ring 9, the front end of the central through hole 91 of the elastic ring 9 has a larger diameter for easier insertion, while the rear end has a smaller diameter to further clamp the pH probe 4 and prevent it from slipping. The elastic ring 9 can be made of a material that does not react with liquids.

[0054] Furthermore, a plurality of anti-slip barbs (not shown in the figures) are provided on the wall of the central through hole 91 of the elastic ring 9 .

[0055] The above multiple implementations can be implemented in parallel.

[0056] The utility model discloses a pH probe buoyancy device, which can effectively solve the problem of inaccurate pH monitoring and unstable readings caused by liquid level floating, and has the following beneficial effects:

[0057] First, the pH probe 4 is integrated into the float 3 and the guide tube 2, and the monitored liquid is introduced through the guide tube 2 to achieve accurate measurement.

[0058] Second, the float 3 is inside the guide tube 2 , and the pH probe 4 is embedded in the float 3 , so that the pH probe 4 floats up and down with the liquid level, effectively improving the monitoring accuracy of the pH probe 4 and the stability of the readings.

[0059] Third, the utility model has no energy consumption requirements and is energy-saving and environmentally friendly.

[0060] Fourthly, the utility model is applicable to various liquid environments and is convenient to clean and calibrate.
