[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Example

[0029] See also Figure 1-4 The present invention provides the following technical solutions: A storage intelligent wireless inspection vehicle, comprising a vehicle body 1 and a track 2 arranged on the upper part of a granary, the vehicle body 1 is provided with a control unit 3, the vehicle body 1 is provided with a detection device for detecting the depth of grain in the granary and a first detector 5 and a second detector 6 arranged at a distance, the track 2 is provided with a detection sensor 7 for adapting to the first detector 5 and the second detector 6, the detection sensor 7 is arranged close to the automatic hatch 8 of the granary, and the controller of the automatic hatch 8 communicates with the control unit 3 to control the opening and closing of the automatic hatch 8. The first detector 5, the second detector 6, the detection sensor 7 can be a photoelectric switch, or a proximity switch, etc. Preferably, the detection device is a radar detector 4.

[0030] Working principle: The control unit 3 controls the vehicle body 1 to travel on the track 2 located on the upper part of the granary. When the detection sensor 7 detects the second detector 6, the vehicle body 1 is in motion, and the control unit 3 communicates with the controller of the automatic hatch 8. At this time, the automatic hatch 8 is opened, and the radar detector 4 can detect the depth of grain in the granary through sound waves. After a period of time, the radar detector 4 completes the detection, and the vehicle body 1 continues to move. When the detection sensor 7 detects the first detector 5, the control unit 3 communicates with the controller of the automatic hatch 8 to close the opened automatic hatch 8, completing the detection. The above process can be used to detect the remaining height of the granary in the granary through this trolley one by one. The specific amount of the stored materials in the granary is calculated according to the height of the stored materials in the granary and the empty warehouse depth. On this basis, the control box is provided with a wireless transmission terminal, and the detection data is uploaded in real time, and is connected to the host computer by wireless communication for real-time monitoring of data.

[0031] Furthermore, the vehicle body 1 includes a chassis 101, a transmission device 102 and a drive motor 103 arranged on the chassis 101, the drive motor 103 is connected to the control unit 3, and the drive motor 103 is also electrically connected to a battery 104, and the battery 104 is provided with a charging plug 105. The vehicle body 1 described in the present invention is convenient for charging, and the power energy is easy to obtain and easy to control. Furthermore, in order to prevent food or other debris from affecting the detection of the radar detector 4, the inventor has provided a wrecker 9 at the lower end of the vehicle body 1, and the wrecker 9 is provided with two, and the radar detector 4 is located between the two wreckers 9. Furthermore, it also includes an audible and visual alarm 106 to serve as a reminder.

[0032] On the basis of the above scheme, in order to prevent the wire from being detached or broken at the joint, the inventor installed an anti-detachment device during wiring, which is as follows: the anti-detachment device includes a transparent connector body 10 and a lock nut 11 connected to the end of the connector body 10, the inner wall of the connector body 10 is provided with a limit platform, the end of the connector body 10 is provided at the deformable body 14, the lock nut 11 is provided with a tightening platform 12 for tightening the deformable body 14 inwardly, and a locking structure 13 is provided between the lock nut 11 and the connector body 10. Preferably, the locking structure 13 is preferably an internal and external thread matching structure. When in use, the wire to be docked is placed in the connector body 10, and then the lock nut 11 is rotated, and the lock nut 11 moves relative to the connector body 10, then the tightening platform 12 provided inside the lock nut 11 will squeeze the deformable body 14 inwardly, so that the deformable body 14 is pressed against the surface of the wire insulation skin, thereby enhancing the tensile strength of the wire at the joint here, and at the same time, there is no need to use insulating tape for bonding, which greatly improves the wiring work efficiency.

[0033] Furthermore, in order to prevent grain particles from entering the anti-slip device and causing adverse consequences such as short circuit, the inventor sets the deformable body 14 to be composed of multiple teeth with gaps, and the tightening platform 12 is a hemispherical cavity or funnel shape. In this way, when the lock nut 11 tightens the teeth, multiple teeth are gathered together, and the ends of the teeth form a ring, which effectively prevents grain from entering the anti-slip device. Furthermore, in order to prevent the water vapor evaporated from the grain from entering the anti-slip device and causing corrosion of the wires, which brings adverse consequences, the inventor sets a fastening rubber ring 15 in the connector body 10, and the connector body 10 is provided with a rubber ring fixing platform 16, which is located on the inner side of the deformable body 14, and the fastening rubber ring 15 is located at the rubber ring fixing platform 16. When in use, the ends of the teeth are squeezed by the lock nut 11 to form a ring, and the ring squeezes the fastening rubber ring 15 to achieve airtightness, which greatly prevents water vapor from entering the anti-slip device, thereby greatly improving the safety and reliability of the present invention.

[0034] On the basis of the above scheme, the control box is provided with a power detection system, which has the function of automatic charging control. The control box is provided with a timed inspection control system, which has the function of timed automatic operation. This is the prior art and will not be described in detail here.
