Description

Technical Field

[0001] The utility model belongs to the technical field of data acquisition devices, and specifically relates to a portable NB-IOT data acquisition device. Background Art

[0002] The data acquisition device is a device that displays and stores the information collected by the sensor and can also transmit it to the platform through communication technology. The current data acquisition instrument includes a protective shell and a module component arranged inside the protective shell. The protective shell is provided with a connecting plug, which is connected to the external connecting line through the connecting plug to perform work.

[0003] However, the connecting plug is fixedly installed outside and exposed to the air, and is connected to the connecting wire when in use. In harsh environmental conditions, such as a dusty environment, the connecting plug is easily affected by dust, resulting in poor contact and affecting the normal operation of the equipment.

[0004] At the same time, the data acquisition device will generate heat when working, and heat will be dissipated by opening heat dissipation holes on the protective shell. However, when not in use, these heat dissipation holes will still be open, and water vapor in the air will enter the protective shell and cause damage to the module components.

[0005] To this end, we proposed a portable NB-IOT data acquisition device, which can not only prevent dust from entering the connection plug and causing poor contact, but also achieve the effect of heat dissipation and preventing water vapor from entering. Utility Model Content

[0006] The purpose of the present invention is to provide a portable NB-IOT data acquisition device, which can not only prevent dust from entering the connection plug and causing poor contact, but also achieve the effect of heat dissipation and preventing water vapor from entering.

[0007] The technical solutions adopted in this utility are as follows:

[0008] A portable NB-IOT data acquisition device comprises a protective shell and a module assembly arranged inside the protective shell, wherein a connecting plug is arranged on one side of the module assembly, and a pushing assembly is arranged on the other side of the module assembly;

[0009] A protective component is provided on one side of the protective shell, and a plurality of through holes are also opened on one side of the protective shell, the positions of the through holes correspond to the positions of the connecting plugs, and the through holes are sealed by providing the protective component;

[0010] The protection component includes four groups of symmetrical fixed blocks arranged on one side of the protection shell, a fixed shaft is arranged between two of the fixed blocks, a rotating sleeve is sleeved on the fixed shaft, a connecting rod is installed on the outside of the rotating sleeve, and a fan-shaped protective sheet is connected to the end of the connecting rod away from the rotating sleeve.

[0011] Furthermore, first heat dissipation holes are opened on both sides of the protective shell, and dustproof nets are arranged on the first heat dissipation holes.

[0012] Furthermore, the module assembly includes a mounting plate slidably arranged on the bottom inner wall of the protective shell, the acquisition module, the NB-IOT module and the power module are installed on the top of the mounting plate, and support plates are arranged on both sides of the mounting plate, the support plates are fitted with the inner wall of the protective shell, and second heat dissipation holes are opened on the support plates, and the second heat dissipation holes are staggered with the first heat dissipation holes.

[0013] Furthermore, the diameter of the through hole is greater than the diameter of the connecting plug.

[0014] Furthermore, the pushing assembly includes a rotating seat arranged on the module assembly, a threaded rod is rotatably arranged on the rotating seat, and one end of the threaded rod away from the rotating seat passes through the protective shell and is installed with a rotating disk.

[0015] Furthermore, four fan-shaped protection sheets are provided, and the four fan-shaped protection sheets form a conical sealing shell when closed.

[0016] The technical effects achieved by this utility model are:

[0017] The rotating disk drives the threaded rod to rotate, thereby pushing the module assembly to move. At this time, the module assembly drives the connecting plug to enter the through hole, and then pushes open the four fan-shaped protective sheets. At this time, the fan-shaped protective sheets drive the connecting rod to make the rotating sleeve rotate on the fixed shaft. Figure 3 As shown, at this time, the four fan-shaped protective sheets are opened, so that the external connection line can be inserted, so that the whole device can work, and at the same time, the first heat dissipation hole overlaps with the second heat dissipation hole to dissipate heat. After use, the threaded rod is driven to rotate in the opposite direction by the rotating disk, so as to push the module assembly to move in the opposite direction. At this time, the module assembly drives the connection plug into the protective shell, and then the four fan-shaped protective sheets are not supported, so as to form a conical sealing shell, so as to protect the through hole and prevent dust from entering. At this time, the first heat dissipation hole and the second heat dissipation hole do not overlap to seal, so as to effectively prevent water vapor from entering. The device can prevent dust from entering the connection plug, thereby causing poor contact, and can also achieve the effect of heat dissipation and preventing water vapor from entering.

DETAILED DESCRIPTION

[0028] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0029] like Figure 1-8 As shown, the technical solution adopted by the utility model is as follows: a portable NB-IOT data acquisition device, comprising a protective shell 1 and a module assembly 2 arranged inside the protective shell 1, a connecting plug 3 is arranged on one side of the module assembly 2, and a pushing assembly is arranged on the other side of the module assembly 2;

[0030] A protective component is provided on one side of the protective housing 1, and a plurality of through holes 4 are also provided on one side of the protective housing 1. The positions of the through holes 4 correspond to the positions of the connecting plugs 3, and the through holes 4 are sealed by providing the protective component;

[0031] The protective assembly includes four groups of symmetrical fixed blocks 5 arranged on one side of the protective shell 1, a fixed shaft 6 is arranged between two fixed blocks 5, a rotating sleeve 7 is sleeved on the fixed shaft 6, a connecting rod is installed on the outside of the rotating sleeve 7, and a fan-shaped protective sheet 8 is connected to the end of the connecting rod away from the rotating sleeve 7.

[0032] Furthermore, the protective shell 1 is used to protect the module assembly 2, and its material can be made of steel sheet or plastic.

[0033] Furthermore, first heat dissipation holes 9 are opened on both sides of the protective shell 1, and dustproof nets are arranged on the first heat dissipation holes 9. The first heat dissipation holes 9 can achieve the effect of heat dissipation, and the dustproof nets can prevent external dust from entering.

[0034] Furthermore, the module assembly 2 includes a mounting plate 10 slidably arranged on the bottom inner wall of the protective shell 1, and a collection module 11, a NB-IOT module 12 and a power module 13 are installed on the top of the mounting plate 10, and support plates 14 are arranged on both sides of the mounting plate 10, the support plates 14 are in contact with the inner wall of the protective shell 1, and second heat dissipation holes 15 are opened on the support plate 14, and the second heat dissipation holes 15 are staggered with the first heat dissipation holes 9.

[0035] Furthermore, the acquisition module 11 is a data collector, and its model is a high-speed EPP parallel port data collector, which is a device specially used for high-speed data acquisition, and usually has a high sampling speed and accuracy. This data collector uses a parallel data interface (EPP parallel port) for data transmission, and can achieve high-speed data acquisition and processing.

[0036] Furthermore, the model of NB-IOT module 12 is WH-NB73-BA multi-band NB-IOT module 12, which realizes the UART to NB-IoT two-way transparent transmission function; domestic full network access, covering mainstream areas around the world; supports NB-IoT serial port, CoAP, UDP; free access to cloud services; supports low power working mode; internal / external SIM card, internal / external antenna optional; supports DNS domain name resolution; supports registration package and heartbeat package mechanism; signal transmission has strong penetration, wide coverage, and large connection.

[0037] Furthermore, the power module 13 is used to provide power.

[0038] Furthermore, when the module assembly 2 needs to work and is pushed by the pushing assembly, the first heat dissipation hole 9 overlaps with the second heat dissipation hole 15 to dissipate heat. When not in use, the first heat dissipation hole 9 and the second heat dissipation hole 15 do not overlap to be sealed, thereby effectively preventing water vapor from entering.

[0039] It should be noted that the connection method and transportation distance between the acquisition module 11, the NB-IOT module 12 and the power module 13 are all prior art, and no further elaboration is given here.

[0040] Furthermore, the diameter of the through hole 4 is greater than the diameter of the connecting plug 3 , so that the connecting plug 3 can extend from the through hole 4 .

[0041] Furthermore, the shaft 6 , the rotating sleeve 7 and the connecting rod are arranged and fixed so that the sector-shaped protective sheet 8 can be rotated.

[0042] Furthermore, four sector-shaped protective sheets 8 are provided, and the four sector-shaped protective sheets 8 form a conical sealing shell when they are closed for protection, thereby protecting the through hole 4 and preventing dust from entering and causing damage to the connecting plug 3.

[0043] Furthermore, the pushing component includes a rotating seat arranged on the module component 2, on which a threaded rod 16 is rotatably arranged. One end of the threaded rod 16 away from the rotating seat passes through the protective shell 1 and is installed with a rotating disk. The threaded rod 16 is driven to rotate by the rotating disk, thereby pushing the module component 2 to move.

[0044] Furthermore, in order to achieve the portable function, an elastic strap can be installed on the outside of the protective shell 1, such as Figure 8 As shown, people can achieve a portable effect through elastic straps.

[0045] The working principle of the utility model is as follows: first, when using the device, the threaded rod 16 is driven to rotate by the rotating disk, thereby pushing the module assembly 2 to move, at this time the module assembly 2 drives the connecting plug 3 to enter the through hole 4, and then pushes the four fan-shaped protective sheets 8 to open, at this time the fan-shaped protective sheets 8 drive the connecting rod to make the rotating sleeve 7 rotate on the fixed shaft 6, such as Figure 3 As shown, at this time, the four fan-shaped protective sheets 8 are opened, so that the external connection line can be inserted, so that the whole device can work, and at the same time, the first heat dissipation hole 9 overlaps with the second heat dissipation hole 15, so as to dissipate heat. After use, the threaded rod 16 is driven to rotate in the opposite direction by the rotating disk, so as to push the module assembly 2 to move in the opposite direction. At this time, the module assembly 2 drives the connection plug 3 to enter the inside of the protective shell 1, and then the four fan-shaped protective sheets 8 are not supported, so as to form a conical sealing shell, so as to protect the through hole 4 and prevent dust from entering. At this time, the first heat dissipation hole 9 and the second heat dissipation hole 15 do not overlap to seal, so as to effectively prevent water vapor from entering. The device can prevent dust from entering the connection plug 3, thereby causing poor contact, and can also achieve the effect of heat dissipation and preventing water vapor from entering.
