Description

Technical Field

[0001] The utility model relates to the technical field of liquid detection, and specifically relates to an automatic alarm device for liquid overflow. Background Art

[0002] When filling liquid, due to the limited storage of liquid, it is necessary to observe in real time whether the liquid is full. If it cannot be effectively controlled before it is full, it is easy to cause liquid overflow, resulting in liquid waste and even pollution of the surrounding environment. Therefore, it is necessary to set a detection device lower than the liquid inlet port at the liquid inlet pipe where the liquid is easy to fill, so as to give an early warning. For this purpose, an automatic liquid overflow alarm device is proposed. Utility Model Content

[0003] The purpose of the utility model is to provide an automatic alarm device for liquid overflow to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic alarm device for liquid overflow, comprising a liquid inlet pipe, a buckle cap is sleeved at the pipe mouth of the liquid inlet pipe, a limiting ring that fits with the inner wall of the liquid inlet pipe is arranged inside the buckle cap, a liquid guide tube is installed in the middle of the buckle cap, a liquid flow channel is formed between the liquid guide tube and the limiting ring, an annular floating plate is arranged in the liquid flow channel, a pressure alarm is installed on the buckle cap, and a touch rod is installed on the upper end of the floating plate for triggering the pressure alarm to alarm.

[0005] Preferably, a connecting tube connected to the liquid flow channel is installed on the buckle cap, a mounting seat is installed on the upper end of the connecting tube, the pressure alarm is installed in the mounting seat, and its contacts correspond to the opening of the connecting tube, and the contact rod is inserted into the connecting tube to trigger the contacts of the pressure alarm.

[0006] Preferably, the inner end of the limiting ring is detachably connected with a clamping ring for limiting the downward displacement of the floating plate.

[0007] Preferably, an exhaust hole is provided on the outer side wall of the connecting pipe.

[0008] Compared with the prior art, the beneficial effects of the utility model are: an automatic alarm device for liquid overflow, which is provided with a buckle cap on the liquid inlet pipe of the tubular container, reduces the inner diameter of the liquid inlet pipe through the liquid guide pipe, and facilitates the insertion of the liquid conveying equipment. The position of the float plate in the liquid flow channel is lower than the pipe mouth of the liquid inlet pipe, so that it can monitor the amount of liquid in the tubular container. When the liquid contacts the float plate, it drives the float plate to float up, and the touch rod triggers the pressure alarm to alarm, thereby alarming to remind the operator to stop the tubing and avoid liquid overflow.

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] See also Figure 1-4 The utility model provides a technical solution: an automatic alarm device for liquid overflow, comprising a liquid inlet pipe 1, a buckle cap 2 is sleeved at the pipe mouth of the liquid inlet pipe 1, a limit ring 3 is arranged inside the buckle cap 2 and is in contact with the inner wall of the liquid inlet pipe 1, a liquid guide tube 4 is installed in the middle of the buckle cap 2, a liquid flow channel 5 is formed between the liquid guide tube 4 and the limit ring 3, an annular floating plate 6 is arranged in the liquid flow channel 5, a pressure alarm 7 is installed on the buckle cap 2, and a touch rod 8 is installed on the upper end of the floating plate 6 for triggering the pressure alarm 7 to alarm.

[0016] A connecting tube 9 connected to the liquid flow channel 5 is installed on the buckle cap 2, and a mounting seat 10 is installed on the upper end of the connecting tube 9. The pressure alarm 7 is installed in the mounting seat 10, and its contacts correspond to the opening of the connecting tube 9. The touch rod 8 is inserted into the connecting tube 9 to trigger the contacts of the pressure alarm 7.

[0017] The inner end of the limiting ring 3 is detachably connected with a clamping ring 11 for limiting the downward displacement of the floating plate 6 .

[0018] An exhaust hole 12 is formed on the outer side wall of the connecting pipe 9 .

[0019] Working principle: When the utility model is used, the buckle cap 2 is buckled on the liquid inlet pipe 1 of the filling container, the limit ring 3 is fitted with the inner wall of the liquid inlet pipe 1, and the pressure alarm 7 is energized. During the filling process, liquid enters the container. As the liquid is continuously injected into the container, the liquid level rises and enters the liquid flow channel. When the liquid level contacts the float plate 6, the float plate 6 is driven to float up. The float plate 6 drives the feeler rod 8 to move upward in the connecting tube 9 until the feeler rod 8 triggers the contact of the pressure alarm 7. The pressure alarm 7 senses the pressure and alarms to remind the operator to stop filling and avoid liquid overflow.
