Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

Fig. 1 shows a schematic view of a pressure measurement structure according to an embodiment of the present invention, please refer to fig. 1, this embodiment discloses a pressure detection device, which is used for detecting the pressure inside a pipeline 1, and the pressure detection device includes a connecting pipe 2, a mounting frame 4, a connecting mechanism 5 and a measuring mechanism 6. Wherein, coupling mechanism 5 threaded connection is on mounting bracket 4, and measuring mechanism 6 passes through coupling mechanism 5 with connecting pipe 2 and communicates. Specifically, the one end of connecting pipe 2 is through first connector 3 and pipeline 1 intercommunication, threaded connection between first connector 3 and the pipeline 1, and mounting bracket 4 sets up in the side of pipeline 1.

Pressure measurement device in this embodiment is when specifically installing, at first fix mounting bracket 4 on pipeline 1, it is specifically fixed through the welded mode, again with coupling mechanism 5 threaded connection on mounting bracket 4, and set up measuring mechanism 6 in coupling mechanism 5's top, then put through the one end and the pipeline 1 switch-on of first coupling 3 with connecting pipe 2, the other end and the coupling mechanism 5 switch-on of connecting pipe 2, make pipeline 1, connecting pipe 2, communicate between coupling mechanism 5 and the measuring mechanism 6, thereby measure the pressure on the pipeline 1 through measuring mechanism 6.

Please refer to fig. 3, the connecting mechanism 5 includes a sleeve 51 in threaded connection with the mounting bracket 4, the other end of the connecting pipe 2 is in threaded connection with the inner side wall of the sleeve 51 through the second connector 7, and the inner side wall of the measuring mechanism 6 and the sleeve 51 is also in threaded connection, so that the disassembly and assembly of the whole device are facilitated, the replacement and maintenance of the measuring assembly 6 are facilitated, the operation is convenient and simple, the operation difficulty is reduced, and the efficiency is improved. In addition, be provided with rubber packing ring 52 between connecting pipe 2 and the measuring mechanism 6 for measuring mechanism 6 can not collide the friction each other with connecting pipe 2 in the installation, and rubber packing ring 52 can improve the gas tightness of being connected between measuring mechanism 6 and the connecting pipe 2 moreover, thereby improves the measuring degree of accuracy.

Referring to fig. 2 and 4, the measuring mechanism 6 includes a pressure gauge 61, and a measuring end of the pressure gauge 61 is in threaded connection with the connecting mechanism 5, so that the pressure gauge 61 is convenient to detach and mount. The measuring mechanism 6 further comprises a plurality of LED lamps 62 arranged on the edge wall of the dial of the pressure gauge 61 and a storage battery 63 arranged on the pressure gauge 61 and used for supplying power to the LED lamps 62, so that the reading on the pressure gauge 61 can be seen more clearly at night when workers patrol, and the pressure can be read more conveniently.

Referring to fig. 5, the battery 63 is connected to the LED lamps 62 through an acousto-optic control circuit. Fig. 4 shows a circuit diagram of the acousto-optic control circuit, and a bridge rectifier circuit composed of four diodes converts the 220V, 50Hz ac voltage of the input circuit into a pulsating dc voltage. The pulsating DC voltage-route R₂And R₁、C₁Voltage Vcc used by the sensor and the logic control circuit is obtained after voltage division and filtering; the other path is connected to the anode of the thyristor SCR.

When the control electrode (grid) of SCR is at high level and the input AC signal V_iWhen cos (wt + phi) is in the negative half cycle, the current is driven by D₂→ ground → D₄→ the LED lamp 62 flows to turn on the lamp, where w is the frequency of the input signal, t is time, and Φ is the phase difference. When V is_iIn the positive half cycle, current flows from lamp → D₃→ ground → D₁And the LED lamp 62 is lit. When the SCR is controlled to a low level, the thyristor is turned off, and no current is generated to drive the LED lamp 62, and the LED lamp 62 is extinguished.

Specifically, the LED lamp 62 is off when there is light, the LED lamp 62 is off when there is no sound, and the LED lamp 62 is on when there is no sound. For the photoresistor R_GIn other words, when there is light, R_G<2k Ω, when pin 1 of the CD4011, that is, one input terminal of the first nand gate is low (ground), pin 3 is high, pin 4 is low, pin 10 is high, and pin 11 is low (the outputs of the left to right nand gates are A, B, C, D respectively), the thyristor is turned off, and the LED lamp 62 is dark. Conversely, if there is no light, R_G>2M Ω, where pin 1 of CD4011 is high, where the output of the first nand gate depends on the state of pin 2, and the state of pin 2 is determined by the noise sensor, and when there is no sound, pin 2 is low, thus a is aHigh, B low, C high, D low, at which time the thyristor is off and the LED lamp 62 is dark. When sound is generated, an alternating current signal is generated at two ends of the microphone, the 2 pin is set to be at a high level through the capacitor, at the moment, A is at a low level, B is at a high level, C is at a low level, and D is at a high level, so that the thyristor is triggered and conducted, the LED lamp 62 is lightened, and meanwhile, the capacitor C can be triggered and conducted due to the fact that the point B is at a high level₃Charged so that when sound disappears, due to C₃And R₈In the presence of a voltage source, so that the point C is at a low level up to C₃The discharge is over, during which the lamp will remain in a bright state until the end of the process.
