Below by drawings and Examples, the technical solution of the utility model is described in further detail.
As shown in Figure 1, be the structural representation of an embodiment of the utility model compressor suction and discharge detection device.In the present embodiment, compressor suction and discharge detection device comprises: air pipe connector 1, air pressure driving mechanism 2 and sensor 3, air pipe connector 1 is communicated with air pressure driving mechanism 2 gas phase, for connecting sucking pipe or the outlet pipe (not shown) of compressor, air pressure driving mechanism 2 has the detection part that sensor 3 can detect, air pressure driving mechanism 2 can make detection part be subjected to displacement under the driving effect of the air pressure from air pipe connector 1, and determine whether the air-breathing of compressor or exhaust normally run by the detection of the misalignment of sensor 3 pairs of detection parts.
In the present embodiment, air pipe connector 1 is communicated with air pressure driving mechanism 2 gas phase, it can be that the connecting tube 4 that utilizes shown in Fig. 1 is communicated with that this gas phase is communicated with, also can directly air pipe connector be connected on air pressure driving mechanism, inner air-flow path is utilized to carry out gas phase connection, as long as the negative air pressure in air pressure driving mechanism can be formed when compressor suction duct air-breathing, or can form the positive air pressure in air pressure driving mechanism when compressor exhaust pipe is vented.
First a kind of structural type of illustratively air pressure driving mechanism is carried out by Fig. 2.Air pressure driving mechanism 2 can specifically comprise: housing 21 and detection part 22, cavity is provided with in housing 21, and the part of detection part 22 is located in cavity, housing 21 also has the gas port 23 with cavity connects, gas port 23 is communicated with air pipe connector 1 gas phase by connecting tube 4, and detection part 22 can be subjected to displacement relative to housing 21 according to cavity inside pressure change.In addition, in order to be fixed air pressure driving mechanism 2, mounting plate 24 can also be set in the side of housing 21.
For the detection part of air pressure driving mechanism, adopt the sensor of different principle, the form of corresponding detection part is not with to realize principle identical yet.Sensor such as shown in Fig. 3 is grating induction switch, and grating induction switch comprises light transmitting terminal and optical receiving end 31, according to the reception of the optical signal from light transmitting terminal, whether optical receiving end determines whether the air-breathing of compressor or exhaust normally run.In Fig. 3 structure, light transmitting terminal and optical receiving end 31 can be arranged on mounting assembly 32, the external circuit coordinated with light transmitting terminal and optical receiving end 31 can be set in mounting assembly 32, and the testing signal of grating induction switch can pass to external equipment by connecting line 33.Here the external equipment mentioned can be that the warning message be electrically connected with sensor 3 presents device, also can be to adopt the warning message of the communication connection of wired or wireless communication mode to present device.It can be sound/light crossing-signal that warning message presents device, the compressor air suction of pointing out operator current by sound signal or optical signal or the runnability of exhaust; It also can be computer that warning message presents device, can present on a display screen according to the testing signal received.
For the compressor suction and discharge detection device adopting grating induction switch as sensor, because its Cleaning Principle is the break-make of optical signal between light transmitting terminal and optical receiving end, therefore detection part can adopt the block piece be made up of light tight material such as metal, rubber, pottery etc., due to lower to the requirement of detection part, therefore may be selected to this cheap material and make detection part.And it is corresponding, air pressure driving mechanism only need arrange block piece driving mechanism in cavity, the blocking position that this mechanism can drive block piece to move into or shift out between light transmitting terminal and described optical receiving end under the air-breathing of compressor or the normal state run of exhaust.This makes it possible to be come to sensor passes signal the stop of light between light transmitting terminal and described optical receiving end by block piece.
Except adopting light sensing switch as except sensor, the sensor of other principles can also be adopted, such as proximity switch, such detection part just can adopt the parts that can be detected within the scope of certain distance by proximity switch, this mode still can utilize the driving of air pressure driving mechanism under the air-breathing of compressor or the normal state run of exhaust and change the distance with proximity switch, thus to sensor passes signal.
For air pressure driving mechanism, more functional part can also be set therein to realize more effectively driving effect, will elaborate later, first further the structure of air pipe connector is described herein.
Fig. 4,5 respectively illustrates the structure of air pipe connector under different visual angles, can see that air pipe connector specifically comprises: can be set in sleeve pipe structure on the sucking pipe of compressor or outlet pipe and the pipe box fixed mechanism of relative position between fixed tube nested structure and compressor.Sleeve pipe structure shown in Figure 4 is the comparatively large and step cutting pattern structure adapted with the liquid container appearance profile of compressor of end diameter, the pipe joint 11 be wherein connected with connecting tube 4 is arranged on the less sleeve pipe structure front end 13 of diameter, and rounded step part is sleeve pipe structure end 12.
Pipe box fixed mechanism is used for fixing sleeve pipe structure and compressor suction duct or outlet pipe, its way of realization has a variety of, such as connect and fix, bonding, bolt connection etc., magnet shown in preferred Fig. 5 connects, consider that the sucking pipe of compressor or outlet pipe place magnet can the metals of adhesive, pipe box fixed mechanism can adopt at least one magnet piece 15 being arranged on sleeve pipe structure end 12.In addition, in order to maintain the tightness between the sucking pipe of sleeve pipe structure and compressor or outlet pipe, airtight assembly 14 can also be also provided with by the contact position between the sucking pipe of sleeve pipe structure and compressor or outlet pipe.
Mention air pressure driving mechanism inside above and more functional part can be set, these functional parts comprise the guide mechanism being arranged on the direction that block piece is subjected to displacement described in shell navigation inside the body, and the resetting-mechanism making described block piece reset under non-operating state.Be such as cylindrical by the Internal periphery of cavity, and block piece driving mechanism comprises with the Internal periphery air-tight fit of described cavity and the cup dolly that can lean described block piece and the guide rod be arranged on described cup dolly, described guide mechanism is the groove with described block piece outline on described housing, described resetting-mechanism is spring, be arranged on described cup dolly with between the one end being communicated with described gas port in described cavity, and be enclosed within described guide rod.
A kind of internal structure external structure way of realization of the air pressure driving mechanism of these functional parts is illustratively provided with below in conjunction with Fig. 6.In figure 6, housing can be made up of the mounting plate of multiple sheet, to facilitate the installation arranging internal structure and inner member, the mounting plate 211 of the top is provided with groove 25, with block piece 221 outline, by the cooperation of groove 25 and block piece 221, block piece 221 can be made to be subjected to displacement along groove about 25, thus to realize leading role.And mounting plate 212 below mounting plate 211 can arrange circular hole, to form the cylindrical cavity of housing.Corresponding block piece driving mechanism 27 comprises the guide rod of cup dolly and below, and can overlap on the guide bar as the spring 26 of consoling mechanism, and is arranged in cup dolly is communicated with gas port one end with cavity, the inner edge 28 of namely inwardly giving prominence to below circular hole in Fig. 6.And mounting plate 213,214 can also be set further below mounting plate 212, carry out support mounting plate 212 and gas port is set.
As we can see from the figure, after air pipe connector connects the sucking pipe of compressor, start compressor, if so aspiratory action can normally carry out, then negative pressure can be formed at housing cavity, and under the effect of negative pressure, block piece driving mechanism 27 entirety moves to gas port direction, Compress Spring 26, corresponding block piece 221 can because of gravity or annexation along with block piece driving mechanism 27 declines together, if so before due to the effect block piece 221 of spring keep off the position between the light transmitting terminal and optical receiving end 31 of grating induction switch always time, so under the effect of negative pressure, block piece can exit this blocking position, now the optical receiving end of sensor just can receive the optical signal that light transmitting terminal sends, thus sensor just have identified the signal that compressor air suction normally runs.And if aspiratory action can not normally carry out, be so just difficult to form negative pressure at housing cavity, and then also just block piece cannot be made to exit blocking position by negative pressure.And when close compressor or when dismantling lower air pipe connector, block piece can get back to original blocking position again under the action of the spring.
If spring 26 to be arranged on the opposite side of block piece driving mechanism 27, then can realize exhaust to detect, after air pipe connector connects the outlet pipe of compressor, start compressor, if so exhaust event can normally carry out, then malleation can be formed at housing cavity, and under the effect of malleation, block piece driving mechanism 27 entirety moves to block piece 221, Compress Spring 26, corresponding block piece 221 upwards can be subjected to displacement together along with block piece driving mechanism 27, block piece 221 is made to enter into position between light transmitting terminal and optical receiving end 31, make the optical receiving end of sensor cannot receive the optical signal of light transmitting terminal transmission, thus sensor just have identified the signal that compressor air-discharging normally runs.And if exhaust event can not normally carry out, be so just difficult to form malleation at housing cavity, and then also just block piece cannot be made to enter blocking position by malleation.And when close compressor or when dismantling lower air pipe connector, block piece can exit blocking position again under the action of the spring.
Except adopting the elastic member of spring and so on as except resetting-mechanism, also the weight of block piece self can be utilized to realize resetting, still can with reference to the structure shown in figure 6, suppose there is no spring 26, then in its natural state, under the Action of Gravity Field of block piece 221, block piece driving mechanism 27 is pressed on the circular hole of mounting plate 212 by block piece 221, now block piece 221 departs from the position of opening the light between transmitting terminal and optical receiving end 31, can not stop that optical receiving end receives the optical signal from light transmitting terminal.If now connect the outlet pipe of compressor, and during its normal exhaust, malleation in the inner chamber of air pressure driving mechanism can overcome the gravity of block piece 221 and block piece driving mechanism 27, shift block piece 221 onto position between light transmitting terminal and optical receiving end 31, stop that optical receiving end receives the optical signal from light transmitting terminal.
Described above is the specific implementation structure of several air pressure driving mechanism, the way of realization that those skilled in the art can select other possible according to technical conceive of the present utility model, composition graphs 1 can be seen in addition, air pressure driving mechanism can also be arranged the structure that sensor established by card, to make air pressure driving mechanism and sensor form the entirety of being convenient to install, transport.
