Description

Technical Field

[0001] This utility model relates to the field of water quality monitoring technology, specifically to an overflow prevention device for waste liquid bottles of water quality monitoring instruments. Background Technology

[0002] The wastewater collection bottle of the water quality monitoring instrument is a container used to collect wastewater generated during the water quality monitoring process or to collect water samples. Generally, the wastewater collection bottle needs to be removed and replaced regularly, and the waste liquid in the waste liquid bottle should be centrally treated. However, if the waste liquid collection bottle is not replaced in time, the waste liquid will overflow from the exhaust valve of the waste liquid collection bottle.

[0003] CN222534974U discloses a laboratory waste liquid collection device to prevent overflow, comprising a waste liquid tank and an overflow prevention tank. The top of the waste liquid tank is threaded with a sealing cap, and a waste liquid pipe is fixedly installed on the sealing cap. A groove is pre-drilled on one side of the waste liquid tank, and the overflow prevention tank is detachably installed within the groove. An overflow port extending into the waste liquid tank is opened on the inner wall of the groove. An overflow pipe is located on one side of the overflow prevention tank, and an early warning component is located at the bottom of the overflow prevention tank. The early warning component includes a buzzer, a movable plate, a contact block, a touch switch, and a spring. This technical solution uses an overflow prevention tank and an early warning component. When the waste liquid level in the waste liquid tank exceeds the overflow port, the waste liquid will flow along the overflow pipe into the overflow prevention tank, triggering an early warning and prompting laboratory personnel to promptly clean the waste liquid in the waste liquid tank, preventing overflow. However, this technical solution places the overflow detection component at the overflow port, meaning the device can only trigger an alarm and response after an overflow occurs, resulting in a relatively late response. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an anti-overflow device for waste liquid bottles in water quality monitoring instruments, which solves the problem of easy overflow when collecting waste liquid in existing waste liquid bottles.

[0005] Technical solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waste liquid bottle anti-overflow device for a water quality monitoring instrument, comprising a waste liquid collection bottle, a sealing plug at the inlet end of the waste liquid collection bottle, an inlet pipe and an exhaust valve in the middle of the sealing plug, a liquid level sensor inside the waste liquid collection bottle located on the sealing plug, the detection height of the liquid level sensor being adjustable, the liquid level sensor detecting the liquid level and generating an alarm signal, and when the liquid level sensor generates an alarm signal, the waste liquid collection bottle is reserved at least once for collecting liquid, and also includes a response component responding to the alarm signal of the liquid level sensor.

[0007] Furthermore, the response component includes an electromagnetic control valve connected to and communicating with the inlet pipe, which closes upon receiving a signal.

[0008] Furthermore, the response component also includes a second electromagnetic control valve disposed between the sealing plug and the exhaust valve, which closes upon receiving a signal.

[0009] Furthermore, the response component includes an alarm connected to a water quality monitor.

[0010] Furthermore, the waste liquid collection bottle includes a rigid part one connected to a sealing plug, a telescopic part is provided below the rigid part one, a rigid part two is connected to the bottom end of the telescopic part, a sliding rod is fixedly installed on the outer ring of the rigid part two, and a snap-fit ​​collar that engages with the sliding rod is fixedly installed on the outer ring of the rigid part one.

[0011] Furthermore, when the liquid level sensor is a contact type, a threaded inner sleeve is fixedly installed on the fixed end of the liquid level sensor, and a threaded outer sleeve is threadedly connected to the outer surface of the threaded inner sleeve. The threaded outer sleeve is fixedly connected to the sealing plug, and the circuit of the liquid level sensor is sleeved inside the threaded inner sleeve and extends to the outside of the sealing plug.

[0012] 1. The overflow prevention device for the waste liquid bottle of this water quality monitor is achieved by using an external retaining ring to secure the waste liquid collection bottle and fixing the sealing plug. By rotating the waste liquid collection bottle, the waste liquid collection bottle and the sealing plug are connected. Wastewater enters the waste liquid collection bottle through the inlet pipe. When the liquid level reaches the response height of the liquid level sensor, the electromagnetic control valve closes to cut off the waste liquid entry and sends an alarm signal to prevent wastewater overflow.

[0013] 2. The overflow prevention device for the waste liquid bottle of this water quality monitor has a telescopic part in the middle of the waste liquid collection bottle. When the electromagnetic control valve fails, the telescopic part will expand under the pressure of the waste liquid, increasing the volume of the waste liquid collection bottle and thus preventing the waste liquid from overflowing.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] See Figure 1-4 An overflow prevention device for waste liquid bottles of a water quality monitoring instrument includes a waste liquid collection bottle 1, a sealing plug 2 at the inlet end of the waste liquid collection bottle 1, an inlet pipe 3 and an exhaust valve 4 in the middle of the sealing plug 2, a liquid level sensor 5 inside the sealing plug 2 located inside the waste liquid collection bottle 1, the detection height of the liquid level sensor 5 is adjustable, the liquid level sensor 5 detects the liquid level and generates an alarm signal, when the liquid level sensor 5 generates an alarm signal, the waste liquid collection bottle 1 reserves at least one volume of collected liquid, and also includes a response component 6 that responds to the alarm signal of the liquid level sensor 5.

[0021] The response component 6 includes an electromagnetic control valve 601 that is connected to and passes through the inlet pipe 3. The electromagnetic control valve 601 closes after responding to a signal. By closing the electromagnetic control valve 601 in response, it is possible to prevent further liquid from entering.

[0022] The response component 6 also includes a second electromagnetic control valve 602 disposed between the sealing plug 2 and the exhaust valve 4. The second electromagnetic control valve 602 closes after responding to a signal. By setting the second electromagnetic control valve 602, the exhaust valve 4 can be closed even if the first electromagnetic control valve 601 fails, thereby preventing liquid from overflowing.

[0023] The response component 6 includes an alarm 603 connected to a water quality monitor, which can prompt the operator to replace the response component 6 in a timely manner.

[0024] The waste liquid collection bottle 1 includes a rigid part 101 connected to the sealing plug 2. A telescopic part 102 is provided below the rigid part 101. A rigid part 2 103 is connected to the bottom end of the telescopic part 102. A sliding rod 104 is fixedly installed on the outer ring of the rigid part 2 103. A snap-fit ​​collar 105 that engages with the sliding rod 104 is fixedly installed on the outer ring of the rigid part 101. With this arrangement, when the electromagnetic control valve 601 fails, the waste liquid entering the waste liquid collection bottle 1 can be squeezed by the rigid part 2 103 to drive the sliding rod 104 to separate from the snap-fit ​​collar 105, and the telescopic part 102 will unfold, increasing the space of the waste liquid collection bottle 1, thereby preventing overflow.

[0025] When the liquid level sensor 5 is a contact type, a threaded inner sleeve 501 is fixedly installed on the fixed end of the liquid level sensor 5. A threaded outer sleeve 502 is threadedly connected to the outer surface of the threaded inner sleeve 501. The threaded outer sleeve 502 is fixedly connected to the sealing plug 2. The circuit of the liquid level sensor 5 is sleeved inside the threaded inner sleeve 501 and extends to the outside of the sealing plug 2. By rotating the threaded inner sleeve 501, it can move up and down relative to the threaded outer sleeve 502, thereby adjusting the height of the liquid level sensor 5. This allows the contact type liquid level sensor 5 to adjust the distance relative to the bottom of the waste liquid collection bottle 1, and thus adjust different liquid level response heights as needed.

[0026] In use, the waste liquid collection bottle 1 is secured by an external retaining ring, and the sealing plug 2 is relatively fixed. By rotating the waste liquid collection bottle 1, the waste liquid collection bottle 1 and the sealing plug 2 are connected. Wastewater enters the waste liquid collection bottle 1 through the inlet pipe 3. When the liquid level of the waste liquid reaches the response height of the liquid level sensor 5, the electromagnetic control valve 601 is closed to cut off the waste liquid from entering, and an alarm signal is issued through the alarm 603 to prevent wastewater overflow.

[0027] At the same time, the second electromagnetic control valve 602 works to close the exhaust valve 4, which can prevent waste liquid from entering and overflowing from the exhaust valve 4 after the first electromagnetic control valve 601 fails.

[0028] Furthermore, the waste liquid collection bottle 1 is configured with a telescopic part 102 in the middle. After the electromagnetic control valve 601 fails, the telescopic part 102 can be expanded under the pressure of waste liquid, thereby increasing the volume of the waste liquid collection bottle 1 and preventing waste liquid from overflowing.
