[0002] Water quality monitors are widely used in water environment management and monitoring, primarily for real-time detection of water quality parameters to ensure a healthy aquatic environment. Existing water quality monitors are mostly fixed with bolts, which is not only inconvenient to install and disassemble, but also prone to loosening over time, especially in environments with rapid water flow or large water surface fluctuations. This loosening problem is more pronounced, seriously affecting the stability and accuracy of the monitor. Bolt wear also gradually weakens the device's fixing effect, requiring frequent maintenance and inspection, increasing operating costs. Therefore, we propose a water quality monitor that is easy to install and disassemble. Utility Model Content

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] This embodiment proposes a water quality monitoring instrument that is easy to assemble and disassemble, such as... Figures 1 to 5 As shown, the device includes a rectangular frame 1 and a water quality monitoring instrument body 2. A base plate 21 is installed at the lower end of the water quality monitoring instrument body 2, and the base plate 21 is installed on the upper surface of the rectangular frame 1. A floating ring 3 is fixedly fitted on the outer side of the rectangular frame 1. In practical applications, bolts are usually used to fix the base plate 21 and the rectangular frame 1 together. However, factors such as water flow, waves, and underwater vibrations will continuously impact and vibrate the bolt connection. Over time, this repeated action may cause the bolts to loosen, affecting the stability of the equipment. In addition, due to the limitations of the aquatic environment, operators face many challenges when disassembling underwater. Slippery surfaces and water pressure make bolt operation more difficult, and limited tool usage further complicates the disassembly process, making it time-consuming and prone to errors, thus increasing the complexity of maintenance and equipment replacement. Therefore, several vertical plates 22 are installed at the lower end of the base plate 21. Each vertical plate 22 has a horizontally positioned slot 23. A pin 6 is slidably fitted into the rectangular frame 1 along the axial direction of the slot 23 at the corresponding position. The pin 6 moves linearly towards the slot 23 until it is fully inserted, thus achieving the engagement connection between the rectangular frame 1 and the water quality monitor body 2. In this embodiment, four vertical plates 22 are arranged in a circular array. It should be noted that the travel distance of the pin 6 needs to be greater than the depth of the slot 23; in this embodiment, the travel distance of the pin 6 is exactly equal to the depth of the slot 23.

[0023] On the basis of the above scheme, we use the pressure difference between the inside and the outside environment of the floating ring 3 as the driving source to realize the linear motion of the plug 6 along the axial direction of the clamping groove 23. Specifically, the inside of the floating ring 3 is fixedly installed along the axial direction of the clamping groove 23. The fixed tube 4 is slidably assembled in the inside of the fixed tube 4 along the axial direction thereof. The piston 5 separates the inner cavity of the fixed tube 4 into two relatively independent spaces, i.e. the inner cavity and the outer cavity. The inner cavity communicates with the inner cavity of the floating ring 3, and the outer cavity communicates with the outside environment. The piston 5 is fixedly connected with the end of the plug 6. When installing the water quality monitor main body 2, first, insert several vertical plates 22 into the middle blank area of the rectangular frame 1. At this time, the clamping groove 23 is just opposite to the plug 6. Then, inject gas into the inner cavity of the floating ring 3. With the increase of the volume of the gas, the pressure in the inner cavity of the floating ring 3 increases, i.e. the pressure in the inner cavity is greater than that in the outer cavity. This makes the piston 5 move towards the rectangular frame 1, i.e. the plug 6 moves linearly towards the clamping groove 23, until the plug 6 is completely inserted into the clamping groove 23. This realizes the quick installation of the rectangular frame 1 and the water quality monitor main body 2. The whole installation process omits the bolt operation step, and only needs to inject gas, which improves the operation safety.

[0024] When disassembling the water quality monitor main body 2, the plug 6 needs to be driven to move away from the clamping groove 23 until it is completely separated from the clamping groove 23. For this purpose, a spring is installed in the outer cavity and is sleeved on the circumferential surface of the plug 6. When disassembling the water quality monitor main body 2, only the air nozzle of the floating ring 3 is opened to reduce the pressure in the inside of the floating ring 3. Then, under the pushing force of the spring, the piston 5 is pushed away from the rectangular frame 1 until the plug 6 is completely separated from the clamping groove 23. Then, the whole water quality monitor main body 2 is pulled upward along the vertical direction, and the separation operation of the rectangular frame 1 and the water quality monitor main body 2 is completed.

[0025] On the basis of the above scheme, the gas pressure in the floating ring 3 will push the piston 5 to move towards the direction close to the rectangular frame 1, and the spring will push the piston 5 to move away from the rectangular frame 1, if the floating ring 3 is damaged or leaks, the gas pressure will decrease, which may cause the bolt 6 to disengage from the slot 23, and the water flow, waves and underwater vibration will produce continuous impact and vibration, which further increases the probability of the floating ring 3 leaking, in order to ensure the connection firmness of the rectangular frame 1 and the water quality monitor main body 2, the bolt 6 needs to always maintain the trend of moving towards the direction close to the rectangular frame 1, for this purpose, a diaphragm 31 is installed in the floating ring 3, the inner cavity of the floating ring 3 is divided into an outer air bag cavity and an inner air bag cavity by the diaphragm 31, the outer air bag cavity is connected with an outer air nozzle 34, the inner air bag cavity is connected with an inner air nozzle 35, a connecting pipe 32 is installed on the diaphragm 31, a one-way valve is installed in the connecting pipe 32, the gas flow direction of the one-way valve is that the outer air bag cavity moves towards the inner air bag cavity, so that the gas can only move from the outer air bag towards the inner air bag, the fixed pipe 4 is installed in the inner air bag cavity, and the inner air bag cavity is wrapped in the rectangular frame 1. The inner cavity of the floating ring 3 is divided into two independent cavities by the diaphragm 31, when the floating ring 3 is impacted, the outer air bag cavity is first subjected to the action force, the gas in the outer air bag cavity is impacted and enters the inner air bag cavity through the connecting pipe 32, so that the air pressure of the inner air bag cavity is increased, and then the air pressure is increased to exert pressure on the piston 5, so that the bolt 6 maintains the trend of moving towards the direction close to the rectangular frame 1, since the rectangular frame 1 wraps the outer surface of the inner air bag cavity, the probability of damage and leakage of the inner air bag cavity is greatly reduced; when the rectangular frame 1 and the water quality monitor main body 2 are disassembled, the inner air nozzle 35 needs to be opened, so that the air pressure of the inner air bag cavity is reduced, and under the action of the spring, the bolt 6 automatically moves away from the rectangular frame 1.

[0026] In addition, in order to protect the outer air bag cavity, a protection frame 33 is installed on the outer surface of the floating ring 3, which protects the floating ring 3, when the floating ring 3 is impacted, the protection frame 33 deforms to absorb part of the impact force.

Therefore, the features limited by "first", "second" can explicitly or implicitly include one or more features.
