Description

Technical Field

[0001] The utility model relates to the technical field of generator monitoring, in particular to a mobile generator signal obtaining module. Background Art

[0002] Mobile generators are backup power sources for communication base stations. In the event of a city power outage, base station personnel operate the generators to generate electricity. However, the power generation of the generators can be falsified, resulting in inflated power generation charges. Therefore, in order to prevent false and ineffective power generation, it is necessary to control and count the number of power generation times and duration, and standardize power generation behavior.

[0003] The mobile generator signal acquisition module is internally integrated with a data acquisition unit, a control unit, a vibration sensing unit, a communication unit, a data storage unit, a power supply unit, a GPS / Beidou positioning unit, etc. The data acquisition unit transmits the collected data to the control unit for processing and storage, and finally transmits the data to the monitoring system or network center through the communication unit.

[0004] Most generator signal acquisition modules in the prior art do not have facilities for protecting the interface. When the external wires connected to the signal acquisition module are accidentally pulled, the interface is easily loosened due to the tension, and even the external wires are partially broken, thus affecting the use of the device. Utility Model Content

[0005] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a mobile generator signal acquisition module to solve the problem that the above interface has no protective facilities.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A mobile generator signal acquisition module includes a shell and a male connector. A mounting groove is provided on one side of the shell. The mounting groove and the male connector are slidably fitted through the groove. A first baffle is fixedly connected to the male connector inside the shell. An annular elastic bag is provided between the first baffle and the inner wall of the shell. The annular elastic bag is sleeved on the outside of the male connector. A sensing mechanism matching the annular elastic bag is provided in the shell. An alarm is provided on the shell. The sensing mechanism is electrically connected to the alarm.

[0008] Preferably, a positioning key is fixedly connected to the outer surface of the male connector, and a key slot matching the positioning key is formed on the shell.

[0009] Preferably, it further comprises a female connector, which is composed of a sleeve and an interface portion, wherein the interface portion is arranged inside the sleeve, and a slot is provided on the inner wall of the sleeve.

[0010] Preferably, a limit snap ring is fixedly connected to the male connector located outside the shell, a side of the limit snap ring away from the shell is provided with an inclined surface, and the limit snap ring matches the groove.

[0011] Preferably, the sensing mechanism comprises a slide groove vertically opened on the inner wall of the shell, a slide plate is slidably fitted in the slide groove, and the slide plate is located directly above the annular elastic bag.

[0012] Preferably, a first electrode block is provided on the top of the sliding plate, a second electrode block matching the first electrode block is fixedly connected to the inner wall of the shell, and the alarm is electrically connected to the second electrode block.

[0013] Preferably, a second baffle is fixedly connected to the male connector located outside the shell, and the second baffle is located between the positioning key and the limiting clamp ring.

[0014] The beneficial effects of the utility model are:

[0015] 1. During the operation of the device, when the external wire connected to the female connector is pulled due to an accident, the male connector can slide to prevent excessive tension between the male connector and the female connector, causing the interface between the male connector and the female connector to loosen, or even break the interface between the external wire and the female connector, thereby affecting the operation of the device.

[0016] 2. During the operation of the device, when the internal temperature of the device is too high, the alarm will sound to alert the surrounding personnel, who can then cool down the device to prevent the internal temperature from being too high and causing damage to the internal electrical components.

[0017] 3. When the device is in use, when the device is located in an area with many and cluttered wires around, the device will sound an alarm when the wires connected to the device are pulled. Therefore, the wires connected to the device can be quickly identified by pulling the wires, further improving the practicality of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will refer to Figures 1 to 4 The embodiments of the present invention are described in detail. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0024] First embodiment:

[0025] A mobile generator signal acquisition module, such as Figure 1-Figure 3 As shown, it includes a shell 1 and a male connector 2, a mounting groove is provided on one side of the shell 1, and the mounting groove and the male connector 2 are slidably matched, a first baffle 3 is fixedly connected to the male connector 2 located inside the shell 1, an annular elastic bag 4 is provided between the first baffle 3 and the inner wall of the shell 1, the annular elastic bag 4 is sleeved on the outside of the male connector 2, a sensing mechanism 5 matching the annular elastic bag 4 is provided in the shell 1, an alarm 6 is provided on the shell 1, and the sensing mechanism 5 is electrically connected to the alarm 6; it also includes a female connector 8, the male connector 2 is connected to the female connector 8, and the other end of the female connector 8 is connected to the external wire; affected by various factors, when the female connector 8 is subjected to tension, the male connector 2 slides along the mounting groove and extends out of the shell 1 to prevent the tension between the male connector 2 and the female connector 8 from being too large, resulting in the loosening of the interface between the male connector 2 and the female connector 8, or even the breakage of the interface between the external wire and the female connector 8, thereby affecting the operation of the device.

[0026] It should be noted that when the male connector 2 slides out of the shell 1 along the mounting groove, the first baffle 3 moves close to the inner wall of the shell 1, thereby squeezing the liquid between the inner wall of the annular elastic bag 4 and the outer surface of the male connector 2, causing the annular elastic bag 4 to expand in the direction away from the male connector 2. When the sensing mechanism 5 senses the expansion of the annular elastic bag 4, the alarm 6 is activated and sounds an alarm to remind the surrounding personnel of an emergency situation here, to prevent the male connector 2 from continuing to be subjected to tension, which may cause the interface between the male connector 2 and the female connector 8 to loosen, or even the interface between the external wires and the female connector 8 to break.

[0027] like Figure 3 As shown, a positioning key 7 is fixedly connected to the outer surface of the male connector 2, and a key slot matching the positioning key 7 is provided on the housing 1. Through the matching arrangement of the positioning key 7 and the key slot, the sliding direction of the male connector 2 can be oriented.

[0028] like Figure 3 and Figure 4 As shown, the female connector 8 is composed of a sleeve and an interface part, the interface part is arranged inside the sleeve, a groove 10 is opened on the inner wall of the sleeve, and a limit snap ring 9 is fixedly connected to the male connector 2 located outside the shell 1. The side of the limit snap ring 9 away from the shell 1 is provided with an inclined surface, and the limit snap ring 9 matches the groove 10; a second baffle 15 is fixedly connected to the male connector 2 located outside the shell 1, and the second baffle 15 is located between the positioning key 7 and the limit snap ring 9.

[0029] During the connection process between the male connector 2 and the female connector 8, the sleeve is first put on the male connector 2 and moved toward the second baffle 15, so that the pins of the male connector 2 are connected with the interface part; through the setting of the inclined surface of the limiting clamp 9, the limiting clamp 9 can enter the sleeve during the movement of the sleeve. When the sleeve moves until the limiting clamp 9 is aligned with the groove 10, the limiting clamp 9 is inserted into the groove 10. At this time, the female connector 8 cannot move away from the male connector 2, and the connection between the male connector 2 and the female connector 8 is completed. This connection method is simple and fast.

[0030] It should be noted that during the connection between the male connector 2 and the female connector 8, due to the influence of friction, the female connector 8 will exert a thrust on the male connector 2 when it moves. The setting of the second baffle 15 can prevent the male connector 2 from being retracted into the shell 1 and moving when the male connector 2 is subjected to the thrust, thereby affecting the connection between the male connector 2 and the female connector 8.

[0031] like Figure 3 As shown, the sensing mechanism 5 includes a slide groove 11 vertically opened on the inner wall of the shell 1, and a sliding plate 12 is slidably fitted in the slide groove 11, and the sliding plate 12 is located directly above the annular elastic bag 4; a first electrode block 13 is provided on the top of the sliding plate 12, and a second electrode block 14 matching the first electrode block 13 is fixedly connected to the inner wall of the shell 1, and the alarm 6 is electrically connected to the second electrode block 14.

[0032] When the male connector 2 is subjected to tension, the annular elastic bag 4 expands in the direction away from the male connector 2, and the sliding plate 12 moves upward along the slide groove 11. When the sliding plate 12 rises to the point where the first electrode block 13 contacts the second electrode block 14, the alarm 6 is energized and sounds an alarm to alert people around.

[0033] It should be noted that when the device is in an area with many and cluttered wires around it, the device will sound an alarm when the wires connected to the device are pulled. Therefore, by pulling the wires, the wires connected to the device can be quickly identified, further improving the practicality of the device.

[0034] Second embodiment:

[0035] Thermal expansion liquid is stored in the cavity between the inner wall of the annular elastic bag 4 and the outer surface of the male connector 2. A radiator is provided on the shell 1, which is not drawn. When the temperature inside the device rises, the thermal expansion liquid expands and causes the annular elastic bag 4 to expand. The annular elastic bag 4 pushes against the sliding plate 12 to rise. When the temperature inside the device rises to a set value, the sliding plate 12 rises until the first electrode block 13 contacts the second electrode block 14, and the alarm 6 is energized and sounds an alarm to alert people around. At this time, the radiator is turned on to cool the shell 1 to prevent the internal temperature of the shell 1 from being too high and causing damage to the internal electrical components.

[0036] It should be noted that in the description of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0037] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0038] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
