Description

Technical Field

[0001] The invention relates to the technical field of net position meters, and in particular to a net position meter that is easy to use. Background Art

[0002] The net position meter is a terminal device that autonomously transmits the location information of the fishing net. It is a new type of navigation aid based on the development of the ship automatic identification system technology. When the ship approaches the fishing net, the AIS system installed on it can receive the fishing net location information sent by the AIS net position meter, so as to avoid the fishing net and ensure the safety of the ship. Fishing boats operating mobile nets can use the net position meter tied to the bamboo poles and other supports to observe the location information of the fishing net at any time, so that in bad weather with low visibility such as fog, heavy rain, and cloudy days, they can quickly find their own fishing nets, avoid unnecessary sea searches, and achieve fuel-saving, green and low-carbon operation methods.

[0003] The existing net position meter is powered by a battery arranged inside the shell, but the battery is arranged together with the main board and cannot be removed during use. When the battery is exhausted, the net position meter needs to be removed from the fishing net rod as a whole to be charged. Therefore, a large number of spare net position meters are needed for replacement, resulting in high cost of use. Summary of the invention

The outer dimensions of the battery shell 53 are adapted to the inner dimensions of the main shell 1, so that the battery shell 53 is slidably connected to the inside of the main shell 1. The connection port 51 is arranged at the upper end of the battery shell 53 and is connected to the battery 54. The charging port 52 is arranged on one side of the upper end of the battery shell 53, and the connection port 51 and the connection port 51 are both connected to the electrodes of the battery 54. Specifically, there are two connection ports 51, and the two connection ports 51 are respectively connected to the positive and negative electrodes of the battery 54. Correspondingly, the connection terminal 7 includes two power terminals 71 respectively connected to the connection ports 51. In addition, in addition to the power terminals 71 corresponding to the two connection ports 51, three terminals 72 for coding are also included, and the three terminals 72 for coding are exposed from the lower side of the partition 6. When it is necessary to write code to the mainboard 8, a specific battery pack with a coding interface is used to connect the power terminal 71 and the terminal 72 for coding. There are two batteries 54, which can be two types of lithium batteries, namely 21700 lithium batteries or 18650 lithium batteries. Due to the different sizes of the two lithium batteries, the internal dimensions of the battery housing 53 are also divided into two types, respectively adapted to the two lithium batteries, while the external shape and size of the battery housing 53 are the same, so as to adapt to the main housing 1.

[0034] The battery housing 53 preferably includes an upper housing 531 and a lower housing 532 connected to the upper housing 531. Both the upper housing 531 and the lower housing 532 are preferably made of a plastic upper housing and a plastic lower housing. The upper housing 531 and the lower housing 532 can be fixedly connected by means such as ultrasonic welding and bonding. In order to facilitate the separate replacement of the battery 54 when the service life of the battery 54 expires, the upper housing 531 and the lower housing 532 are preferably connected in a detachable manner. As a preferred embodiment, the upper housing 531 and the lower housing 532 are connected by snap connection and / or bolt connection. Specifically, a plurality of locking blocks 533 are provided on both sides of the lower housing 532, and a plurality of locking holes 534 are provided on both sides of the upper housing 531.

Electrode elastic pieces 56 that are inserted and matched with the power supply terminals 71 are respectively provided in the two notches 55. The two electrode elastic pieces 56 are respectively connected to the positive and negative electrodes of the battery 54. Each time the battery pack 5 is replaced, when the power supply terminal 71 is inserted into the electrode elastic piece 56, friction will be generated with the inner side of the electrode elastic piece 56, effectively preventing the power supply terminal 71 or the electrode elastic piece 56 from rusting and causing poor contact. The electrode elastic pieces 56 are arranged in the notches 55 to avoid damage to the battery 54 caused by contact between the positive and negative electrodes during normal storage.

At the same time, the second sealing ring 12 can also play a certain sealing role between the sealing cap 4 and the main housing 1. The main housing 1 and the adapter housing 2 are preferably threadedly connected. After installation, the main housing 1 and the adapter housing 2 can be adhesively fixed, and a third sealing ring 13 can also be provided between the main housing 1 and the adapter housing 2. To improve the sealing performance between the adapter housing 2 and the antenna housing 3, a fourth sealing ring 14 is provided between the adapter housing 2 and the antenna housing 3.

The antenna housing nut 15 is threadedly connected to the upper end of the adapter housing 2. To improve the stability of the main board 8 in the antenna housing 3, a card slot is preferably provided in the antenna housing 3, and both sides of the main board 8 are arranged in the card slot. To prevent the antenna housing 3 from rotating relative to the adapter housing 2 when the antenna housing nut 15 is rotated, which may cause damage to the main board 8, the VHF antenna 9 and the connection terminal 7, a second limiting structure is preferably provided between the antenna housing 3 and the adapter housing 2. The second limiting structure is used to prevent the antenna housing 3 from rotating in the adapter housing 2. The second limiting structure is preferably an external tooth-shaped structure 31 provided on the antenna housing 3 and an internal tooth-shaped structure 22 provided on the adapter housing 2. The external tooth-shaped structure 31 and the internal tooth-shaped structure 22 cooperate with each other and should be made as fine as possible so that the angle can be appropriately adjusted during installation to prevent the main board 8 and the card slots on both sides from generating large stress.

[0039] To facilitate finding this device during use, the adapter housing 2 is preferably a transparent adapter housing, and a plurality of indicator lights are provided inside the adapter housing 2. The indicator lights are preferably light-emitting diodes 16. The light-emitting diodes 16 can be arranged on the main board 8. A plurality of light-emitting diodes 16 can be used, and the light-emitting diodes 16 are arranged around the horizontal periphery of the adapter housing 2. The light-emitting diodes 16 can be welded to both sides of the main board 8, and by bending the pins, some of the light-emitting diodes 16 are arranged towards the other two sides. To avoid too strong light, a plurality of stripes 21 are preferably provided on the outer side of the adapter housing 2.

[0040] It is also preferably provided with an installation opening 81 on the main board 8, and the positioning antenna 10 is inclined and arranged in the installation opening 81.

[0041] In order to prevent it from falling off after unscrewing the sealing cap 4, it is also preferably connected with an anti-detachment rope 17 between the main housing 1 and the sealing cap 4. Since it does not affect the normal rotation of the sealing cap 4, one end of the anti-detachment rope 17 is preferably connected to the lower side of the sealing cap 4. In order to enable the device to still be placed vertically, a groove 41 is provided on the lower side of the sealing cap 4, and the anti-detachment rope 17 is arranged in the groove 41.

[0042] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, the other parts not specifically described belong to the prior art or common general knowledge. Without departing from the principle of the present invention, several improvements and refinements can also be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
