Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] In the present invention, unless otherwise clearly defined and limited, the terms "mount", "connected", "connected", "fixed", etc. shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] The present invention provides the following technical solutions:

[0026] Embodiment 1

[0027] Please refer to Figures 1-4 , the present invention provides a technical solution: A mounting bracket for a COD monitoring device for sewage treatment, including a base 1, a first mounting bracket 2 fixedly connected to the top of the base 1, a second mounting bracket 6 slidably connected to the periphery of the first mounting bracket 2, a shrinking mechanism 3 arranged outside the second mounting bracket 6, a mounting plate 5 fixedly connected to the top of the second mounting bracket 6, a mounting mechanism 4 arranged inside the second mounting plate 5, and a COD detector arranged on the top of the mounting mechanism 4;

[0028] The contraction mechanism 3 includes a connecting frame 34. The connecting frame 34 is fixedly connected to the left side of the second mounting frame 6. At the top inside the connecting frame 34, a fixed rod 33 is fixedly connected. The bottom of the fixed rod 33 is fixedly connected to the top outside the mounting frame. A sliding plate 32 is slidably connected to the periphery of the fixed rod 33. The sliding plate 32 is fixedly connected to the left and right sides of the first mounting frame 2. A first spring 35 is sleeved on the periphery of the fixed rod 33. On the left side of the connecting frame 34, a fixed frame 31 is fixedly connected. A pull rod 39 is slidably connected inside the fixed frame 31. On the left side of the pull rod 39, a pull plate 38 is fixedly connected. On the right side periphery of the pull rod 39, a limit disc 301 is fixedly connected. A second spring 37 is sleeved on the periphery of the pull rod 39. On the right side of the limit disc 301, a plug rod 36 is fixedly connected.

[0029] Further, the top of the first spring 35 is fixedly connected to the top inside the sliding plate 32, and the bottom of the first spring 35 is fixedly connected to the top outside the second mounting frame 6. When the plug rod 36 does not limit the sliding plate 32, the first spring 35 can drive the first mounting frame 2 to return to its original position through the sliding plate 32, enabling the first mounting frame 2 to contract into the second mounting frame 6, which is convenient for the staff to transfer and store the first mounting frame 2 and the second mounting frame 6.

[0030] Further, the outside of the second spring 37 is fixedly connected to the inside of the fixed frame 31, and the inside of the second spring 37 is fixedly connected to the outside of the limit disc 301. Release the acting force on the pull plate 38, so that the second spring 37 drives the plug rod 36 to move through the limit disc 301, enabling the plug rod 36 to insert into the connecting frame 34 and the sliding plate 32 to limit the position of the sliding plate 32.

[0031] Further, circular holes corresponding to the size of the plug rod 36 are opened on the inside of the sliding plate 32 and the connecting frame 34, and the plug rod 36 is inserted into the circular holes. Through the opened circular holes, the plug rod 36 can insert into the inside of the sliding plate 32 and the connecting frame 34 to limit the sliding plate 32, making it difficult for the first spring 35 to drive the first mounting frame 2 to retract into the second mounting frame 6 through the sliding plate 32.

[0032] Embodiment 2

[0033] Please refer to Figures 1-4 On the basis of Embodiment 1, the installation mechanism 4 further includes a cylinder 46. The cylinder 46 is fixedly connected to the top of the second mounting frame 6. At the bottom of the cylinder 46, a lifting plate 44 is fixedly connected. On the left and right sides at the bottom of the lifting plate 44, limit plates 43 are fixedly connected. Inside the limit plates 43, a bidirectional threaded rod 41 is threadedly connected. On the right side of the bidirectional threaded rod 41, a fixed disc 47 is fixedly connected. A threaded block 42 is threadedly connected to the periphery of the bidirectional threaded rod 41. At the top of the threaded block 42, a clamping plate 45 is fixedly connected.

[0034] Furthermore, a sliding groove corresponding to the movement track of the threaded block 42 is formed inside the lifting plate 44, and the threaded block 42 is slidably connected inside the sliding groove. By providing the sliding groove, the threaded block 42 is more stable during movement.

[0035] Furthermore, the lifting plate 44 is arranged at the bottom of the COD monitor 7, and the bottom of the COD monitor 7 is in close contact with the top of the lifting plate 44. The COD monitor 7 can be supported by the provided lifting plate 44.

[0036] During the actual operation process, when this device is in use and when the COD monitor 7 for sewage treatment needs to be installed, pull the pull plate 38, so that the pull plate 38 drives the insertion rod 36 to move through the sliding rod and the limit disk 301, making the insertion rod 36 move away from the inside of the sliding plate 32. Two workers simultaneously pull the first mounting bracket 2 and the second mounting bracket 6, so that the first mounting bracket 2 squeezes the first spring 35 through the sliding plate 32. When the heights of the first mounting bracket 2 and the second mounting bracket 6 are adjusted to appropriate positions, release the force on the pull plate 38, so that the second spring 37 drives the insertion rod 36 to move through the limit disk 301, enabling the insertion rod 36 to insert into the inside of the connecting frame 34 and the sliding plate 32 to limit the position of the sliding plate 32, making it difficult for the first spring 35 to drive the second mounting bracket 6 to retract into the first mounting bracket 2. Fix the mounting plate 5 with bolts, so that the first mounting bracket 2 and the second mounting bracket 6 can be fixed on the wall, making the first mounting bracket 2 and the second mounting bracket 6 more stable during use;

[0037] Place the COD monitor 7 on the top of the lifting plate 44, rotate the fixed disk 47, so that the fixed disk 47 drives the bidirectional threaded rod 41 to rotate, and the bidirectional threaded rod 41 drives the clamping plate 45 to move through the threaded block 42, enabling the clamping plate 45 to clamp the COD monitor 7. When the height of the COD monitor 7 needs to be adjusted, adjust the height of the lifting plate 44 through the cylinder 46, so that the lifting plate 44 can drive the COD monitor 7 to move up and down, enabling the height of the COD monitor 7 to be adjusted, making the COD monitor 7 suitable for use requirements at different heights, and making the detection data more accurate when the staff detects sewage through the COD monitor 7;

[0038] When the first mounting bracket 2 and the second mounting bracket 6 need to be stored or transported, pull the insertion rod 36 so that the insertion rod 36 does not limit the sliding plate 32. The first spring 35 can drive the first mounting bracket 2 to return to its original position through the sliding plate 32, enabling the first mounting bracket 2 to retract into the second mounting bracket 6, facilitating the staff to transport and store the first mounting bracket 2 and the second mounting bracket 6.

[0039] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent in such process, method, article or device. Without further limitation, an element defined by the statement "comprising one..." does not exclude the existence of additional identical elements in the process, method, article or device comprising the said element.
