Description

Technical Field

[0001] The utility model relates to the technical field of charging piles, and in particular to a liquid level warning structure of a coolant recovery tank of a charging pile. Background Art

[0002] Liquid level measurement is in great demand in real life. Whether it is for liquid level measurement of non-transparent devices or for other occasions where the liquid level is not allowed to exceed a certain limit to ensure safety, measurement and early warning are of great significance, especially in the application of charging pile coolant recovery tanks.

[0003] There are many types of liquid level gauges on the market, including suspension, radar, and ultrasonic measurement methods. These methods often require complex mechanical structures and high costs to achieve high measurement accuracy. However, in charging pile coolant recovery tanks, precise liquid level measurement is not necessary; simply providing a warning when the level reaches a warning level is sufficient. Therefore, we propose a liquid level warning structure for charging pile coolant recovery tanks. Utility Model Content

[0004] The purpose of the present invention is to provide a liquid level warning structure for a charging pile coolant recovery tank to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A liquid level warning structure for a charging pile coolant recovery tank comprises a charging pile coolant recovery tank body, wherein a coolant level warning component is provided inside the charging pile coolant recovery tank body;

[0007] The coolant level warning assembly includes two straight conduits, a floating plate is slidably connected to the periphery of the two straight conduits, a first liquid level height limit seat is provided on the top of the two straight conduits, a second liquid level height limit seat is provided on the periphery of the two straight conduits near the bottom, and a circular scraper is provided on the periphery of the floating plate and inside the charging pile coolant recovery tank body.

[0008] As a preferred solution of the present invention, a connecting pipe is provided on one side of the top of the charging pile coolant recovery tank body, and the other end of the connecting pipe extends to the bottom of the charging pile coolant recovery tank body.

[0009] The technical effect of adopting the above further solution is: by connecting the connecting pipe to the external equipment, the charging pile coolant is introduced into the charging pile coolant recovery tank body for recycling.

[0010] As a preferred solution of the present invention, a switch valve is provided on the periphery of the charging pile coolant recovery tank body near the bottom, and the switch valve is connected to the interior of the charging pile coolant recovery tank body.

[0011] The technical effect of adopting the above further solution is: by opening the switch valve, the coolant stored inside the charging pile coolant recovery tank body is discharged, which is convenient for subsequent recycling and processing.

[0012] As a preferred solution of the present invention, an alarm system is provided at the top center of the charging pile coolant recovery tank body.

[0013] As a preferred solution of the present invention, a plurality of connecting rods are arranged around the floating plate and the circular scraper.

[0014] The technical effect of adopting the above-mentioned further scheme is: the floating plate is connected to the circular scraper through a connecting rod. When the charging pile coolant is injected into the charging pile coolant recovery tank body, the floating plate rises due to the buoyancy of the liquid, and then drives the circular scraper connected to it to rise. When the charging pile coolant level inside the charging pile coolant recovery tank body decreases, the floating plate will also drive the circular scraper to descend. At the same time, during the descent, the circular scraper comes into contact with the inner wall of the charging pile coolant recovery tank body, scrapes off the residual charging pile coolant on the inner wall, and keeps the inner wall of the charging pile coolant recovery tank body clean.

[0015] As a preferred solution of the present invention, abutment seats are provided on the top and bottom of the floating plate, and the straight conduit passes through the abutment seats.

[0016] As a preferred solution of the present invention, pressure sensors are provided inside both the first liquid level limit seat and the second liquid level limit seat.

[0017] The technical effect of adopting the above-mentioned further scheme is: when the charging pile coolant is injected into the charging pile coolant recovery tank body, the float plate in the coolant level warning assembly rises due to the continuous injection of liquid, and finally the abutment seat on the top of the float plate will contact the first liquid level height limit seat set at the top of the linear conduit. After the internal pressure sensor of the first liquid level height limit seat is subjected to the pressure transmitted by the abutment seat, it will send a signal to the alarm system to alert external staff.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] In the present utility model, a coolant level warning component is provided in the charging pile coolant recovery tank body. When the charging pile coolant is injected into the charging pile coolant recovery tank body, the float plate in the coolant level warning component rises due to the continuous injection of liquid, and finally the abutment seat on the top of the float plate will contact the first liquid level height limit seat provided at the top of the linear guide tube. After the pressure sensor inside the first liquid level height limit seat is subjected to the pressure transmitted by the abutment seat, it will send a signal to the alarm system to warn the outside staff. When the charging pile coolant is injected into the charging pile coolant recovery tank body, the float plate rises due to the buoyancy of the liquid, and then drives the circular scraper connected to it to rise. When the charging pile coolant level inside the charging pile coolant recovery tank body drops, the float plate will also drive the circular scraper to descend. At the same time, during the descent, the circular scraper contacts the inner wall of the charging pile coolant recovery tank body, scrapes off the residual charging pile coolant on the inner wall, and keeps the inner wall of the charging pile coolant recovery tank body clean.
