Description
Technical Field
The utility model relates to a density test probe technical field, in particular to density measurement probe that stability is high.
Background
For open lead-acid batteries, it is often necessary to measure the electrolyte density to determine the remaining capacity of the battery. The density measuring probe is required to be installed on the storage battery, and the density detecting component or the sensor is immersed into the electrolyte to complete the measurement of the electrolyte density. However, in actual use, as the use time increases, impurities and fine air bubbles inside the battery adhere to the density detection member or the sensor, which affects the operation of the sensor, and may increase the error of the detected density value.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a density measurement probe that stability is high mentions the problem in order to solve the background art.
In order to achieve the above object, the present invention provides the following technical solutions:
a density measuring probe with high stability comprises a probe body, a sensor arranged below the probe body, an air pump, an air guide pipe and a shell; the bottom of the probe main body is provided with an installation part and a sealing part; the shell is fixed below the probe body; the shell is provided with a plurality of filtering holes; the sensor extends out of the lower part of the probe body and is positioned in the shell; the air pump is arranged in the probe body; the air duct is positioned in the shell; one end of the air duct is connected with the air pump, and the other end of the air duct faces the sensing head of the sensor.
To further describe the present invention, the air duct is of "L" shape, including a vertical portion and a horizontal portion connected to the lower end of the vertical portion.
To the further description of the present invention, the installation portion is provided with external threads.
To the utility model discloses a further description, be equipped with annular mounting groove and install the sealing washer in the mounting groove in the sealing.
To the utility model discloses a further description, it includes rectangular shape hole and round hole to filter the hole.
The utility model has the advantages that:
in the use, the impurity and the micro-bubble of the response head position department of attaching to the sensor can pass through the air pump air feed, and gas gets into from the one end of air duct to discharge from the other end of air duct, the port of air duct is facing to the response head of sensor, and the spun gas directly blows towards the response head of sensor, consequently can clear away impurity and bubble from the sensor, makes the sensor reply normal function, and the design of dustcoat can prevent that impurity from getting into inside, plays the protecting effect.
Drawings
FIG. 1 is an overall structure of the present invention;
fig. 2 is a diagram showing a state of use of the present invention mounted on a battery.
Detailed Description
The invention is further explained below with reference to the drawings:
as shown in fig. 1-2, a density measuring probe with high stability comprises a probe body 1, a sensor 2 arranged below the probe body 1, an air pump 3, an air duct 4 and a shell 5; the bottom of the probe body 1 is provided with an installation part 11 and a sealing part 12; the shell 5 is fixed below the probe body 1; the shell 5 is provided with a plurality of filtering holes 51; the sensor 2 extends out from the lower part of the probe body 1 and is positioned in the shell 5; the air pump 3 is arranged in the probe body 1; the air duct 4 is positioned in the shell 5; one end of the air duct 4 is connected with the air pump 3, and the other end of the air duct faces the sensing head of the sensor 2; the probe body 1 is installed and fixed on an upper cover plate 61 of a storage battery 6 through an installation part 11, a sealing part 12 prevents electrolyte 62 of the storage battery 6 from leaking outwards, in the design, an external thread 111 is arranged on the installation part 11 and is assembled with the storage battery 6 in a threaded connection mode, an annular installation groove 121 and a sealing ring 122 installed in the installation groove 121 are arranged on the sealing part 12, the installation groove 121 is located above the installation part 11, the sealing ring 122 is abutted to an installation hole of the upper cover plate 61 of the storage battery 6, so that a sealing function is achieved, after the installation is completed, a shell 5, a sensor 2 and an air guide pipe 4 are all located inside the storage battery 6, the electrolyte 62 in the storage battery 6 enters from a filter hole 51 of the shell 5, the sensor 2 can detect the density of the electrolyte 62 in the storage battery 6, impurities can be isolated in the filter hole 51, the detection head position of the sensor 2 can be attached with impurities and micro-bubbles, the impurities and the micro-bubbles can influence the detection precision of the sensor 2, therefore, the air pump 3 is adopted to supply air for the air guide tube 4, the air is discharged from the other end of the air guide tube 4, and the air is blown to the detection head position of the sensor 2 after being discharged, so that the impurities and the bubbles are removed from the sensor 2, and the starting time of the air pump 3 is set in various modes, the mode of timing starting can be adopted according to the actual use condition, the mode of timing cleaning is adopted, or the mode of manual control is adopted for cleaning, and under the condition that the detection is abnormal, the air pump 3 is automatically controlled by the through hole control system to start and clean, the structure is convenient to use, the air pump 3 is combined in the probe main body 1, and the installation mode does not need to be redesigned.
In this design, the air duct 4 is "L" shaped, and includes a vertical portion 41 and a horizontal portion 42 connected to the lower end of the vertical portion 41.
In this design, the filtering holes 51 include elongated holes and circular holes.
The above description is not intended to limit the technical scope of the present invention, and any modification, equivalent change and modification made to the above embodiments according to the technical spirit of the present invention are still within the scope of the technical solution of the present invention.
