Description
Technical Field
The utility model discloses a have and hold up signal lamp measuring stick is applicable to the directional usefulness such as dotting with the prism of total powerstation, belongs to the surveying instrument field, and the specially adapted distance is far away or comparatively bleeped place carries out the directional work of dotting with the prism of total powerstation.
Background
Among the present engineering survey, the total powerstation needs orient when setting up a station, often because hold up the pole personnel when measuring stick horizontal bubble is not placed in the middle, the observer just orients, produces the gross error easily, when carrying out the house and confirming the right, the prism is adjusting the position, perhaps holds up the pole personnel still when moving, and the observer just takes notes, produces the gross error easily. In field measurement, a ruler holding person usually uses a method of preventing an observer from illuminating the prism, and then enabling the prism to face the observer when the ruler is held, so as to avoid being illuminated by mistake. However, when the measuring rod is rotated, shaking is often caused to cause the air bubbles to be not centered. In addition, also rotate from the survey nail because of the rotation easily, perhaps produce the displacement, hold up pole personnel and observer and do not carry out fine interaction, this measuring stick can solve this type of problem. To the utility model relates to a do not have this type of product on the measuring stick market of taking the signal lamp, the producer does not have similar design.
Disclosure of Invention
The purpose of the invention is as follows: in order to improve the condition, the utility model discloses a measuring stick of signal lamp is held up in area not only provides the effective succinct interchange function of observer and the information of holding up the pole person, can also provide convenience for the observer looks for the target simultaneously, is convenient for find the prism on the measuring stick fast to and hold up the pole person and carry out the directional and prism information acquisition work of total powerstation when finishing preparing, solved the problem of holding up the chi personnel by the wrong observation when finishing not preparing, the while has accelerated the searching speed of prism in the condition such as light is not good.
The technical scheme is as follows: a measuring rod with a signal lamp is composed of a switch, an indicating signal lamp, a power supply and a simple circuit consisting of wires for supplying power to the signal lamp. When in measurement, the device can be communicated with a ruler holding person and an observer basically, and is used when the holder is ready to use. The measuring rod with the well-held signal lamp comprises a measuring rod and a signal system, the measuring rod comprises an inner rod, an outer rod and a prism, bubbles are arranged in the prism, the inner rod is arranged in the outer rod, the outer diameter of the inner rod is equal to the inner diameter of the outer rod, the inner rod can slide in the outer rod, one end of the inner rod is positioned outside the outer rod, the prism is arranged at the end of the inner rod, the signal system comprises a lens, a signal lamp, a live wire, a zero wire, a switch, a small copper sheet at the positive pole of a battery jar, a spring and a card box, and a battery is arranged in the card; the signal lamp is arranged on the inner wall of the inner rod, and the lens is arranged on the outer wall of the inner rod opposite to the signal lamp; the inner rod is a hollow rod, a live wire lead and a zero wire lead are placed in the inner rod, the signal lamp is arranged on the inner wall of the inner rod, the lens is arranged on the outer wall of the inner rod opposite to the signal lamp, and an observer can see the signal lamp through the lens; the negative pole of the battery is contacted with the spring, the spring is connected with the zero line lead and then is connected with the negative pole of the signal lamp, the positive pole of the battery is contacted with the positive small copper sheet of the battery jar, the positive small copper sheet of the battery jar is connected with the fire wire lead and is connected with the positive pole of the signal lamp through the switch to form a closed loop. When the bubble centering device is used, a support person well supports the measuring rod on the directional point, and lightly presses the switch in the hand when the bubbles are centered. At the moment, the signal lamp is turned on, and an observer obtains a signal instruction through a total station or direct observation and carries out observation recording. Because, the observer puts the hand on the switch in advance and holds up the chi, when waiting that the bubble is placed in the middle, press down the signal lamp alright gently. Compared with a rotary measuring rod, the device has the advantages that shaking is very small, and the bubble centering can still be guaranteed. The bottom of the measuring rod is not displaced. The observer can record when seeing the signal lamp is always on.
Furthermore, the switch is arranged in the middle of the outer wall of the outer rod, so that a user can conveniently hold the ruler by putting hands on the switch in advance.
Further, the distance between the signal lamp and the prism is less than 5cm, and the signal lamp is close to the prism, so that the signal lamp can help an observer to find the prism to a certain extent, and the orientation and dotting speed is increased.
Has the advantages that: the utility model discloses a measuring stick of signal lamp has been held up in area has solved the problem that the prism was surveyd by the mistake when not holding up, simple structure facilitates the use, and low cost easily promotes.
Drawings
FIG. 1 is a diagram of a structure of a measuring rod with a signal lamp;
in the figure, 1 is a lens, 2 is a signal lamp, 3 is a wire of a live wire, 4 is a wire of a zero wire, 5 is a switch, 6 is a small copper sheet on the positive electrode of a battery jar, 7 is a spring, 8 is a card box, and 9 is a prism.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
The measuring rod with the signal lamp well supported as shown in fig. 1 comprises a measuring rod and a signal system, wherein the signal system comprises a lens 1, a signal lamp 2, a live wire 3, a zero wire 4, a switch 5, a battery jar positive minimum copper sheet 6, a spring 7, a card box 8 and a prism 9, and the distance between the signal lamp 2 and the prism 9 is less than 5 cm.
When the ruler is used, the measuring rod is placed at the orientation point, one hand of a supporter is placed on the switch, and the other hand assists in holding the ruler. When the bubbles are centered, the switch 5, the signal lamp 2, the lead 3 of the live wire, the switch 5, the small copper sheet 6 at the positive electrode of the battery jar, the battery, the spring 7 and the lead 4 of the zero line are lightly pressed to form a closed loop. At the moment, the signal lamp is turned on, and an observer obtains a signal instruction through a total station or direct observation and carries out observation recording. Because the holding person puts the hand on the switch in advance to hold the ruler, when the bubble is placed in the middle, press down the signal lamp gently alright. Compare rotatory measuring stick and rock very little, still can guarantee that the bubble is placed in the middle, measuring stick bottom can not take place the displacement yet. The observer can record when seeing that the signal lamp is always on, and the signal lamp is close to the prism, so the signal lamp can also help the observer to find the prism to a certain extent, and the speed of orientation and dotting is accelerated.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
