Abstract
The utility model discloses a liquid level detection device, which comprises a storage slot and a control panel with a display, wherein the control panel is fixed on the outer wall of the storage slot, a test rod is vertically arranged along the inner wall of the storage slot, the test rod is provided with an infrared liquid level sensor, and the infrared liquid level sensor is connected with the control panel through wires. The liquid level detection device overcomes the undetermined defects of adhesion of mechanical hairpins and reed pipes, abrasion of mechanical switches and demagnetization of permanent-magnet steels and the like in traditional floating type mechanical liquid level detection devices such as buoys and floating balls and the like, thereby preventing the liquid level detection device from being suddenly out of order during the use process, and being capable of guaranteeing long-term steady operation.
Description
Technical field
The utility model relates to a kind of liquid level detection device, belongs to the liquid level detection range.
Background technology
Traditional liquid level detection device major part is to adopt floating drum or ball float to reflect liquid level signal, and floating drum is the mechanical drive by pulley and wire rope, drives the mechanical switch action; Ball float then is the mechanical shift by the permanent-magnet steel that is installed on float inside, and the dry-reed relay that comes adhesive to be installed on reference test bar inside moves to reach the purpose that detects liquid level.No matter be floating drum or ball float, all inevitably have uncertain factors such as mechanical hair fastener, tongue tube adhesion, mechanical switch wearing and tearing, permanent-magnet steel demagnetization, cause liquid level detection device malfunctioning, make troubles for people's use.
The utility model content
At the problem that above-mentioned prior art exists, the utility model purpose is to provide a kind of liquid level detection device, can effectively solve above-mentioned problems of the prior art.
The technical solution of the utility model is: liquid level detection device, comprise storage tank, have the control panel of display, control panel is fixed in the storage tank outer wall, vertically be provided with a reference test bar along the storage tank inwall, the infrared ray liquid level sensor is housed on the reference test bar, and the infrared ray liquid level sensor links to each other with control panel by lead.
As preferably, be provided with the signal converter circuit module in the described control panel.
As preferably, described reference test bar is detachably connected on the storage tank inwall.
As preferably, described infrared ray liquid level sensor is installed in the mounting hole on the reference test bar.
The beneficial effects of the utility model are: overcome uncertain defectives such as the mechanical hair fastener that floating mechanical liquid level detection devices such as conventional pontoon, ball float exist, tongue tube adhesion, mechanical switch wearing and tearing, permanent-magnet steel demagnetization, avoid the unexpected malfunctioning situation of liquid level detection device in the use, can guarantee long-term stable operation.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
As shown in Figure 1, liquid level detection device, comprise storage tank 1, have the control panel 2 of display, control panel 2 is fixed in storage tank 1 outer wall, vertically be provided with a reference test bar 3 along storage tank 1 inwall, infrared ray liquid level sensor 4 is housed on the reference test bar 3, and infrared ray liquid level sensor 4 links to each other with control panel 2 by lead.Be provided with the signal converter circuit module in the described control panel 2.Described reference test bar 3 is detachably connected on storage tank 1 inwall.Described infrared ray liquid level sensor 4 is installed in the mounting hole on the reference test bar 3, and the quantity of infrared ray liquid level sensor 4 and installation site can be adjusted according to its purposes and needs.
When the utility model uses, when the fluid to be measured in the storage tank 1 touches infrared ray liquid level sensor 4 surfaces, changed opticpath, the infrared receiving tube of infrared ray liquid level sensor 4 inside is in cut-off state, send signal, signal is transferred to control panel 2 after microelectronics amplifies processing, by its inner signal converter circuit module signal is converted into discernible data then, and the display of passing to control panel 2 shows.In addition, reference test bar 3 is detachably connected on storage tank 1 inwall, after long-term the use, if some infrared ray liquid level sensors 4 damage, reference test bar 3 can be disassembled the infrared ray liquid level sensor 4 that more renews and get final product, and safeguards simple, convenient.
