Description

Technical Field

[0001] The utility model relates to the technical field of liquid meters, in particular to a liquid meter used for an online water quality monitor. Background Art

[0002] An online water quality monitor is an instrument used to monitor various water quality parameters in real time. It can automatically and continuously monitor changes in water quality and provide real-time data and analysis results. These instruments are widely used in environmental protection, water treatment, aquaculture, industrial monitoring and other fields. The liquid meter of an online water quality monitor is an important component of the water quality monitoring system. It is mainly used to accurately measure and record the amount of liquid passing through the monitor to ensure the accuracy and reliability of the monitoring results.

[0003] When various water quality parameters in a water body are detected by an online water quality monitor and a liquid meter is needed for assistance, the metering tank is first installed on the base of the monitor, and then water is injected into the metering tank. At this time, the flow or liquid level of the liquid in the metering tank is monitored through the upper metering sensor and the lower metering sensor on the fixed seat, and the signal is then transmitted to the control system. However, in order to confirm the accuracy of the online water quality monitoring data, the staff often use tools such as handheld water quality monitors to re-inspect the water body. However, when the staff took out the metering tank and placed it on the table, they did not support and reinforce it, but placed the metering tank directly on the table, resulting in poor fixation between the metering tank and the table. Then, when the staff's arms and body collided with the metering tank due to personnel movement, the metering tank was prone to tipping over, causing water to flow out and damage the water sample, thereby affecting the water quality detection work.

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.

[0019] See also Figure 1-Figure 5 The utility model provides a technical solution: a liquid meter for an online water quality monitor, comprising a metering tank 1, a fixing seat 2 and an upper metering sensor 3, a fixing seat 2 is connected to the middle of the outer wall of the metering tank 1, and an upper metering sensor 3 is installed on the top of the fixing seat 2, and a lower metering sensor 4 is installed on the bottom of the fixing seat 2, a monitor base 5 is connected to the bottom middle of the bottom end of the metering tank 1, and an auxiliary mechanism 6 is provided at the bottom end of the metering tank 1, and the auxiliary mechanism 6 includes a rotating pin 601, a limiting seat 602, a fixing pin 603, a mounting seat 604, a supporting seat 605, a supporting rod 606, a fixed suction cup 607, a guide seat 608 and a threaded rod 609, rotating pins 601 are welded on both sides of the bottom end of the metering tank 1, and the outer wall of the rotating pin 601 is connected to the limiting seat 602, and the side of the bottom end of the metering tank 1 close to the rotating pin 601 A mounting seat 604 is welded, and a support seat 605 is docked inside the mounting seat 604; a fixing pin 603 is connected to the inside of the limit seat 602, and a fixing hole is provided on the side of the bottom end of the metering tank 1 close to the limit seat 602; support rods 606 are slidably connected on both sides of the support seat 605, and a fixing groove corresponding to the limit seat 602 is provided inside the monitor base 5; a fixed suction cup 607 is connected to the bottom end of the support rod 606, and a guide seat 608 is welded to the top end of the support rod 606; a threaded rod 609 is threadedly connected to the middle part of the guide seat 608, and the bottom end of the threaded rod 609 is connected to the support seat 605 through a bearing seat; the limit seat 602 is "L"-shaped, and the support seat 605 is "F"-shaped; the rotating pin 601 and the limit seat 602 are rotated, and the mounting seat 604 and the support seat 605 are snap-fitted.

[0020] When the measuring tank 1 is in a state of being moved and the measuring instrument 5 is in a state of being moved, the fixing pin 603 is manually moved to disengage the measuring tank 1 from the measuring tank 1, thereby canceling the limit of the limit seat 602, and then the measuring tank 1 is moved to disengage the connection with the monitor base 5, and then the limit seat 602 is rotated to face upward to prevent it from affecting the placement of the measuring tank 1 on the table. Because the mounting seat 604 is connected to the measuring tank 1, the support seat 605 is inserted into the mounting seat 604 in advance, and at this time, the mounting seat 604 and the support seat 605 are engaged, thereby limiting the support seat 605, and because the threaded rod 609 and the guide seat 608 are threadedly connected, the threaded rod 609 is manually rotated to make the guide seat 608 move downward, and because the guide seat 608 is connected to the support rod 606, the guide seat 608 moves and drives the support rod 606 to move together;

[0021] After that, the support rod 606 moves downward, driving the fixed suction cup 607 to move downward together, and at this time, the support rod 606 slides along the support base 605 until the fixed suction cup 607 is connected to the smooth desktop, thereby increasing the fixing area and fixing effect between the metering tank 1 and the desktop, improving its supporting stability, and thus preventing the metering tank 1 from tipping over after being hit and affecting the detection, and subsequently only needing to move the support base 605 upward to disconnect the support base 605 from the mounting base 604;

[0022] When the metering tank 1 needs to be installed inside the water quality online monitor, since the rotating pin 601 is connected to the limit seat 602, first rotate the limit seat 602 to make it rotate along the rotating pin 601 until the limit seat 602 is facing downward away from the rotating pin 601, and then move the metering tank 1 so that the limit seat 602 is docked with the monitor base 5. At this time, the monitor base 5 and the limit seat 602 are in a snap-fit connection, and then the metering tank 1 is limited, and then the fixing pin 603 is moved to dock with the metering tank 1, and then the limit seat 602 is limited to prevent it from rotating at will. Then, there is no need to dock the metering tank 1 with the monitor base 5 to complete the limit installation of the liquid meter, saving time and energy, thereby playing a role in preventing tipping and assisting installation when the liquid meter is used in the water quality online monitor.

[0023] To sum up, when using the liquid meter for the online water quality monitor, the metering tank 1 is first installed on the monitor base 5, and then water is injected into the metering tank 1. At this time, the flow or liquid level of the liquid in the metering tank 1 is monitored through the upper metering sensor 3 and the lower metering sensor 4 on the fixed seat 2, and then the signal is transmitted to the control system. This is the existing technology and will not be elaborated on here. The auxiliary mechanism 6 is used to increase the fixing area and fixing effect between the metering tank 1 and the desktop, thereby improving its support stability and preventing the metering tank 1 from tipping over after a collision and affecting the detection; and the liquid meter can be limitedly installed by only moving the metering tank 1 to dock with the monitor base 5, saving time and energy. The content not described in detail in this description belongs to the existing technology known to professional and technical personnel in this field.
