Description
Technical field
The utility model relates to a kind of material level gauge, specifically refers to rod-type Ultrasonic Position-meter.
Background technology
The mounting means of existing ultrasonic material level meter adopts flange or screw thread to install usually, and this mounting means is still feasible in normal conditions.But in some particular scene, such as tank deck has darker flange well, the ultrasound wave sending out ultrasonic probe transmitting will be interfered and cisco unity malfunction by flange borehole wall gear letter.
Utility model content
The purpose of this utility model is to provide rod-type Ultrasonic Position-meter, and the ultrasound wave solving probe transmitting in special fluid reservoir is subject to the problem of interfering, and what guarantee liquid tank level was measured normally carries out.
The purpose of this utility model is achieved through the following technical solutions:
Rod-type Ultrasonic Position-meter, comprise mount pad and be arranged on the cylinder in mount pad, cylindrical shell is connected with in the lower end of described mount pad, the output terminal of described cylinder runs through mount pad and is placed in cylindrical shell, the output terminal of described cylinder is connected with the towbar that longitudinal section is pincushion, and at the end of towbar, probe is installed, the middle part of cylindrical shell is run through and is provided with fixed block, groove is provided with in fixed block, on cylinder lateral wall, correspondence is provided with the through hole be communicated with groove, slide in groove and be provided with grip block, and one end of grip block is connected with the inwall of groove by spring, the other end of grip block is provided with the curved surface matched with towbar.When the utility model uses, fixed block is arranged on the top of fluid reservoir, regulate the deep distance of towbar according to the degree of depth of fluid reservoir top flange well in time, be subject to the interference of flange well inwall with the ultrasound wave avoiding probe to launch and cause probe normally to work, during work, start cylinder, the towbar be connected with the output terminal of cylinder is made to start to move down at cylinder endosome, be arranged in the probe of towbar end then along with the liquid level started fluid reservoir that moves down of towbar is measured, in the downslide process of towbar, longitudinal section is that the middle part of the towbar of pincushion is in the state caved inward, when the contact of incline plane of the outer wall also grip block end of towbar, the acting force that grip block is subject to towbar radial direction makes its bottom along groove move, spring is squeezed and produces deformation simultaneously, when spring reaches largest deformation amount, spring produces a maximum elastic force to grip block, make the outer wall close contact of grip block and towbar, and then make towbar no longer continue to move down, thus limit excessively moving down of towbar, prevent the probe being positioned at towbar end from directly contacting with liquid medium to be measured, improve the degree of accuracy measured.
Also comprise limiting plate, described limiting plate is arranged on the top of towbar.The grip block being arranged in fixed block can make certain restriction to the movement of towbar, but when spring is impaired or elastic force is not enough to support grip block to towbar stable fixing, towbar then there will be the phenomenon excessively moved down, probe is directly caused to contact with liquid level, not only can cause measurement data out of true, also certain damage be caused to probe; The utility model, at the top mounting limit plate of towbar, can effectively prevent excessively moving down of towbar, and when contacting with the upper surface of grip block bottom the two ends of limiting plate, then towbar cannot continue to move down.
Be provided with travel switch in the bottom at described limiting plate two ends, travel switch is connected with cylinder by wire.When the curved surface close contact of towbar outer wall and grip block, towbar no longer continues mobile, and arranges fluid reservoir inside due to towbar, and external staff cannot observe the situation in tank, therefore cylinder can be in overload state for a long time, greatly reduces the serviceable life of cylinder; The utility model is provided with travel switch bottom the two ends of limiting plate, before limiting plate is contacted with the upper surface of grip block, travel switch first contacts with the upper surface of grip block, travel switch contacts the braking realizing towbar by cutting off between cylinder and power supply, reduce the light condition of cylinder, improve the serviceable life of cylinder.
The utility model compared with prior art, has following advantage and beneficial effect:
1, the grip block that the utility model is arranged in fixed block can make certain restriction to the movement of towbar, but when spring is impaired or elastic force is not enough to support grip block to towbar stable fixing, towbar then there will be the phenomenon excessively moved down, probe is directly caused to contact with liquid level, not only can cause measurement data out of true, also certain damage be caused to probe; The utility model, at the top mounting limit plate of towbar, can effectively prevent excessively moving down of towbar, and when contacting with the upper surface of grip block bottom the two ends of limiting plate, then towbar cannot continue to move down;
2, the grip block that the utility model is arranged in fixed block can make certain restriction to the movement of towbar, but when spring is impaired or elastic force is not enough to support grip block to towbar stable fixing, towbar then there will be the phenomenon excessively moved down, probe is directly caused to contact with liquid level, not only can cause measurement data out of true, also certain damage be caused to probe; The utility model, at the top mounting limit plate of towbar, can effectively prevent excessively moving down of towbar, and when contacting with the upper surface of grip block bottom the two ends of limiting plate, then towbar cannot continue to move down;
3, the utility model is provided with travel switch bottom the two ends of limiting plate, before limiting plate is contacted with the upper surface of grip block, travel switch first contacts with the upper surface of grip block, travel switch contacts the braking realizing towbar by cutting off between cylinder and power supply, reduce the light condition of cylinder, improve the serviceable life of cylinder.
