Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a visual liquid level detection device. Background Art

[0002] Due to the high moisture content and turbid water quality in the on-site environment, the raw water treatment level gauges commonly used in the past often displayed abnormal detection signals, resulting in inaccurate level detection, causing great trouble for operation and affecting the normal operation of the water pump. For example, the water in the pool may be completely drained, but the level gauge still shows water, causing the water pump to idle for a long time and shortening the service life of the water pump. Or the water in the pool may overflow, and the level gauge may still detect a low water level even though the pool is full, causing sewage overflow, environmental pollution, and a significant impact on the environmental protection of the workshop. In addition, high-precision level gauges are easily damaged when used in harsh environments and are relatively expensive to purchase. Utility Model Content

[0020] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are not intended to limit the scope of protection of the present invention.

[0021] In order to achieve the above purpose, the present invention proposes a visual liquid level detection device, such as Figure 1 、 2 As shown, including:

[0022] Dimension ruler 1, horizontal pointer 2, disc 4, stainless steel pipe 6, iron pipe 8, stainless steel ball 10, limit switch and angle iron;

[0023] The top of the stainless steel ball 10 is welded to the bottom end of the stainless steel pipe 6, and the stainless steel ball 10 can rise and fall due to the buoyancy of water; the length of the stainless steel pipe 6 is cut according to the actual situation on site, and the iron pipe 8 is put on the outer surface of the stainless steel pipe and maintains the set spacing; the bottom end of the iron pipe 8 is located at the top of the water pool 9; a horizontal pointer 2 is set on the top of the stainless steel pipe 6 by welding to indicate the actual liquid level; the lowest and highest positions of the stainless steel ball 10 are determined according to the lowest water level and the highest water level in the water pool 9, and a mark is made on the angle iron according to the position indicated by the horizontal pointer 2 at this time, and a limit switch is set at the mark. The disc 4 is set on the stainless steel pipe 6 between the two limit switches by welding to touch the limit switch; the outer surface of the iron pipe 8 and the limit switch are both fixed on the angle iron, and the angle iron can support each component; the size ruler 1 is attached to the angle iron, and the length of the size ruler 1 is the length of the upper and lower movable range of the horizontal pointer 2, which can facilitate personnel inspection, improve inspection efficiency, prevent risks, and reduce equipment hidden dangers. The direction of the size ruler 1 should be installed in a place where it is convenient for personnel to check or where the camera can capture it, so that personnel can find abnormal conditions in time.

[0024] Stainless steel tube 6 has a diameter of 1 cm. Iron tube 8 is 50 cm long and 1.5 cm in diameter. Disc 4 has a diameter of 10 cm. Stainless steel tube 6 is longer than iron tube 8. Iron tube 8 supports stainless steel tube 6, ensuring it can move vertically without tilting. The positions of horizontal pointer 2 when stainless steel ball 10 is at the bottom and top of pool 9, respectively, represent its vertical range of motion.

[0025] The process of using the visual liquid level detection device proposed by the utility model is as follows:

[0026] Fix the visual liquid level detection device on the platform of the water pool, put the stainless steel ball into the water pool, and connect the lowest and highest positions of the stainless steel ball to the PLC (Programmable Logic Controller) through the wiring of the limit switch to realize the automatic control of the water pump. It can control the automatic opening or closing of the water pump and also make an alarm on the screen. The stainless steel ball rises and falls due to the buoyancy of the water, thereby driving the connected stainless steel pipes to follow the up and down movement, and the disc fixed on the stainless steel pipe will move up and down. When it is detected that the water in the pool has reached the lowest position, the disc will touch the lever of the lowest limit switch, and the lowest limit switch will be triggered. The signal will be connected to the start and stop circuit of the water pump or collected into the PLC, and all the water outlet pumps will be stopped urgently; when it is detected that the water in the pool has reached the highest position, the disc will touch the lever of the highest limit switch, and the highest limit switch will be triggered. The signal will be connected to the start and stop circuit of the water pump or collected into the PLC, and all the water inlet pumps will be stopped urgently; and when the water in the pool reaches the lowest or highest position, the alarm can be set to flash and the voice prompt can be set through the WINCC screen.

[0027] The device is simple to modify and has low cost, and can be extended to all similar types of equipment.

[0028] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
