Description

Technical Field

[0001] This utility model relates to the technical field of water quality monitoring equipment, and specifically to a dissolved oxygen sensor installation device. Background Technology

[0002] Contact oxidation is a wastewater treatment technology that utilizes a biofilm process. It involves the decomposition of organic matter in wastewater through the contact of a biofilm formed by bacteria and other microorganisms on the surface of a packing material. In this system, the oxygen required for microbial metabolism is typically provided by an aeration blower, and the dissolved oxygen content in the water is monitored in real time by a dissolved oxygen sensor installed in the contact oxidation tank.

[0003] However, the installation method of dissolved oxygen sensors in the existing technology has the following defects: First, the vertical installation method in the existing technology causes the sensor probe to be directly exposed in the rising path of aeration bubbles, resulting in fluctuations in the measurement data due to bubble interference; Second, the submersible pipe head of the sensor lacks effective protection and is easily invaded by rainwater in the open environment, causing corrosion and damage to the internal components of the sensor, affecting the accuracy of the monitoring data and the service life of the equipment. Utility Model Content

[0015] In some embodiments, 150°≤α≤165°.

[0016] In some embodiments, the first interface is an internal thread formed at the A-port; the end of the extension tube connected to the first interface is provided with an external thread adapted to the internal thread of the A-port.

[0028] The specific embodiments of this utility model are described in detail below. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0029] In this utility model, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the orientation in the assembled and used state. "Inner" and "outer" refer to the inner and outer sides relative to the outline of each component itself.

[0030] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of the utility model described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0031] This utility model provides a dissolved oxygen sensor mounting device, such as Figure 1 As shown, the device includes a submersible pipe 4, a first interface 3, and a second interface.

[0032] The interior of the submersible pipe 4 has a wiring channel extending from port A at one end to port B at the other end. This wiring channel is used to arrange the dissolved oxygen sensor connection wire 5 of the dissolved oxygen sensor 6. Of course, for most submersible pipes, the interior is hollow, meaning that it has its own internal channel, and the dissolved oxygen sensor connection wire 5 can run through this channel.

[0033] In this application, the submersible pipe 4 is a bend with two openings at the beginning and end, namely pipe opening A and pipe opening B. The geometric center lines of pipe opening A and pipe opening B form a spatial angle α that is either coplanar or non-coplanar. Wherein, the included angle α is an obtuse angle.

[0034] Furthermore, the submersible pipe 4 is a circular bend pipe, comprising a first pipe segment having a first axis extending along its length and a second pipe segment having a second axis extending along its length. The first axis and the second axis form a coplanar spatial angle α. Preferably, 150°≤α≤165°. A first interface is located at the end of the first pipe segment, and a second interface is located at the end of the second pipe segment, i.e., the first interface 3 and the second interface are respectively located at pipe opening A and pipe opening B. The first interface 3 is used to connect an extension pipe, so that the extension pipe and the submersible pipe 4 form a continuous pipeline. The connection method here refers to a detachable connection, such as a connection method through flanges, clips, etc. In the technical solution of this utility model, a threaded connection is used to achieve a detachable connection between the extension pipe and the submersible pipe 4.

[0035] Specifically, in one optional embodiment, the extension tube is a straight tube with an internal thread at port A. The end of the extension tube connected to the first interface has an external thread that matches the internal thread at port A. In this embodiment, the extension tube is threaded only at one end. This embodiment can extend the submersible tube 4 to adjust the installation depth of the dissolved oxygen sensor 6. However, it is limited by the length of a single extension tube. Specifically, the maximum installation depth adjustment of the dissolved oxygen sensor 6 is limited by the length of the extension tube. To exceed this adjustment depth, a longer extension tube needs to be used; it is not possible to add another extension tube on top of an already installed extension tube.

[0036] Therefore, this application provides another specific embodiment, specifically: the first interface is an internal thread formed at the A-port. Both ends of the extension tube are respectively provided with mutually compatible internal and external threads; wherein the external thread is compatible with the internal thread of the A-port. In this specific embodiment, both ends of the extension tube are threaded, allowing for the continuous stacking of extension tubes, adding more extension tubes on top of the previous one.

[0037] It should be noted that the "A-port internal thread", "extension pipe external thread", and "extension pipe internal thread" mentioned above do not refer to a specific type of internal or external thread. The prefixes "A-port" and "extension pipe" are added before "internal thread" and "external thread" to distinguish them in description.

[0038] The extension pipe is rotatably connected to the pool opening 7. This application provides two methods for implementing the rotatable connection.

[0039] Implementation Method 1: A mounting base 2 is provided on the outer wall of the extension pipe. The extension pipe passes through the submersible pipe channel formed on the pool opening 7 and extends downward. The mounting base 2 and the pool opening 7 form a gravity-limiting fit, that is, the pool opening 7 supports the mounting base 2. The advantage of this implementation method is that it is easy to operate, but it is not fixed in the vertical and circumferential directions. Therefore, in actual use, some shaking may occur, or the submersible pipe 4 may rotate after long-term operation.

[0040] To address this, a second implementation method is provided: the extension tube and the pool opening 7 are rotatably connected via a rotating structure; the rotating structure includes: a mounting base 2, multiple pin holes, and a pin. The mounting base 2 is fixedly connected to the pool opening 7 and is arranged circumferentially around the extension tube. The multiple pin holes are circumferentially distributed on the outer walls of the mounting base 2 and the extension tube, and simultaneously penetrate the mounting base 2 and the extension tube radially. The pin can be inserted into the pin hole, and the pin is at least outside the pin hole. This implementation method provides fixation in both the vertical and horizontal directions, but it is cumbersome when the extension tube needs to be rotated. It requires removing the pin, rotating the extension tube, and finally re-inserting the pin to achieve angle adjustment.

[0041] The second interface is located at pipe port B and is used to install the dissolved oxygen sensor 6. The connection between the dissolved oxygen sensor 6 and the second interface can be a threaded connection. Many commercially available dissolved oxygen sensors 6 have threads at the tail. Therefore, simply configure the second interface with a thread compatible with the sensor's tail. Of course, other connection methods such as flanges can also be used between the dissolved oxygen sensor 6 and the second interface.

[0042] By using the above technical solution, in practical applications, by appropriately adjusting the installation depth and angle of the dissolved oxygen sensor 6, the detection end of the dissolved oxygen sensor 6 will not be directly facing the rising path of the bubble, thus avoiding fluctuations in the measurement data due to bubble interference.

[0043] In addition, the dissolved oxygen sensor mounting device also includes a submersible cap 1. The submersible cap 1 can cover the other end of the extension tube connected to the first interface. The submersible cap 1 can provide protection and prevent rainwater from entering and causing corrosion damage to the internal components of the sensor.

[0044] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0045] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0046] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
