Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

As shown in fig. 1, the circuit power-on indicating device of the present invention comprises a power supply 1, a power-on indicator 2 and a conducting wire 3, wherein the power-on indicator 2 and the power supply 1 are connected in series through the conducting wire 3 to form a loop, and the power-on indicator 2 is installed on the ground through a metal upright post 4; the lead 3 connected to each of the power indicator 2 is a first lead 31 and a second lead 32, respectively, and the power indicator 2 emits light if a current passes through at least two of the first lead 31, the second lead 32 and the metal column 4 connected to the power indicator 2.

In the construction process, individual joints are often connected poorly to form an open circuit, and normal power supply cannot be achieved. For the test of reconnecting of joint disconnection in turn among the prior art, the utility model discloses a circuit circular telegram indicating device through setting up a plurality of series connection electric indicator 2, can be swiftly whether each wire 3 of audio-visual instruction department put through, if the discovery does not put through, can confirm rapidly that the position of taking place to open a way makes things convenient for constructor to seek the problem at the very first time, handles rapidly, saves the line-checking time, improves the efficiency of construction.

As shown in fig. 2, the power-on indicator 2 of the present invention includes a housing 21 and an indicator 22, the indicator 22 is installed in the housing 21, one end of the metal column 4, which is far away from the ground, passes through the housing 21 and is connected to the indicator 22, and the first wire 31, the second wire 32 and the metal column 4 are all connected to the indicator 22.

Optionally, in some embodiments of the present invention, the indicator light 22 has 3 electrodes, defined as an a pole, a B pole and a C pole in sequence. The pole a is connected to one end of the first wire 31, the pole B is connected to one end of the second wire 32, and the pole C is connected to one end of the metal conductor 4. In this manner, when at least two of the a pole connected to the first lead wire 31, the B pole connected to the second lead wire 32, and the C pole connected to the metal conductor 4 are energized, the indicator lamp 22 emits light. That is, the indicator lamp 22 emits light when at least two of the a pole connected to the first wire 31, the B pole connected to the second wire 32, and the C pole connected to the metal conductor 4 have current flowing therethrough. Thus, the operator can determine that the power indicator 2 is working properly, and the short circuit of the wire is avoided. According to the method, the constructor can confirm the position of the open circuit.

In actual power supply operation, both ends of the wire 3 are connected to the indicator lamp 22 through joints, and there are generally two cases: if all the joints before the joint (in the series direction) are connected well and the joint is disconnected, the power indicator 2 connected with the previous joint emits light due to the passing of current, and the power indicator 2 connected with the joint does not emit light due to the passing of no current; if the front connector is disconnected, the power indicator 2 connected to the connector located at the rear does not emit light at this time. Therefore, the constructor can quickly find the position of the open circuit by only looking at the first non-luminous power-on indicator 2, the joint is connected, the time for connecting the joint again in sequence is greatly saved, and the construction efficiency is improved.

Further, the indicator lamp 22 is an inert gas indicator lamp. Optionally, the indicator light 22 is a neon indicator light or a hernia indicator light. Preferably a neon indicator. The neon indicator lamp is a cold cathode glow discharge tube, the radiation spectrum of which has the ability of penetrating through the atmosphere, the color is bright, gorgeous and colorful, and the luminous efficiency is obviously superior to that of the common incandescent lamp. Because of the cold cathode characteristic, the temperature of the lamp tube is below 60 ℃ when the lamp tube works, so the lamp tube can be placed in the open for sunning and raining or work in water. And because of the working characteristics, the spectrum of the neon indicator lamp has strong penetrating power, and the neon indicator lamp can still keep good visual effect in rainy days or foggy days.

As shown in fig. 2, the housing 21 is a transparent plastic housing. The transparent plastic shell is beneficial to the irradiation of the light of the indicator light and the observation of constructors. Preferably, the shell is made of transparent acrylic plate materials. The lamp box made of acrylic has the characteristics of good light transmission performance, pure color, rich color, attractive appearance, smoothness, long service life, no influence on use and the like, and has two effects of day and night. In addition, the impact resistance is sixteen times that of common glass, and the glass is suitable for being installed in construction areas.

In addition, round holes are formed in the two sides and the bottom of the shell 21, so that the first lead 31, the second lead 32 and the metal upright post 4 can be conveniently connected in use. When a disconnection is detected at a certain position, the connector corresponding to the lead 3 can be inserted into the housing 21 and connected with the indicator lamp 22. Simple structure and convenient implementation.

Further, the metal upright 4 is a steel cone. One end of the steel cone 4 penetrates through the bottom of the shell 21 and is connected with the C pole of the indicator light 22, and the other end of the steel cone is inserted into the ground. The end of the steel cone 4 inserted into the ground is sharp, and can be inserted into the ground only by lightly knocking. The power supply 1 is a 48-500V direct current power supply. The specific voltage intensity is selected according to the actual construction site.
