Detailed Description

The present utility model will be described in detail with reference to the accompanying drawings.

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

Example 1

As shown in fig. 1, the mounting box comprises a hoop 3, and the mounting box body is connected to the side surface of the hoop 3. It should be noted that, the installation box of this design is installed to contact net compensation arrangement (weight piece) through the staple bolt, if there are other mounting means, will staple bolt 3 replace corresponding facility can.

The installation box body and the anchor ear 3 have two connection modes, one is directly welded on the side face of the anchor ear 3. Another is that a mounting plate 2 is welded vertically to the side face of the anchor ear 3, for example, as shown in fig. 7, the mounting plate 2 is welded to the lower edge of the anchor ear 3, and the mounting box body is mounted on the mounting plate 2. For the first design mode, the box body 1 of the mounting box body is required to be made of an anti-collision metal material; for the second design mode, the mounting box body is not required to be made of metal materials, but the same problem of collision prevention is considered, and the upper surrounding frame 22 is preferably connected to the edge of the mounting plate 2, as shown in fig. 8, so that the mounting box body is surrounded to prevent the collision of the weight piece and the like.

The installation box body comprises a box body 1, the box body 1 is hollow, an upper cover 4 seals the opening of the box body 1 to form a cavity structure, and the electronic device is installed in the cavity. As shown in fig. 2, mounting positions including a distance sensor mounting position 13, a temperature sensor mounting position 14, a switch mounting position, a battery mounting position 15, and the like are provided on the bottom plate 11 of the case 1, wherein the distance sensor mounting position 13 is necessary. On some or all of these mounting locations, screws, screw holes, etc. for auxiliary fixing components are designed.

The positions of the sensor mounting positions are determined according to design requirements, for example, in some application scenarios, the sensor can only be located in the middle of the bottom plate 11, and in some application scenarios, the sensor can only be located in the corner positions of the bottom plate 11, and then the mounting positions on the bottom plate 11 need to be designed at corresponding positions. As shown in fig. 9, in order to design the mounting positions for mounting the sensors in the side corner region and the middle region of the chassis 11, respectively, the mounting positions for the sensors may be designed in other regions than these two design positions.

The sensor needs to detect the distance to ground, and therefore, if the mounting plate 2 is designed, the mounting plate 2 cannot shield the sensor, i.e., the mounting plate 2 cannot shield the mounting position on the base plate 11 for mounting the sensor. As shown in fig. 8 and 9, a hollow area 21 is left on the mounting plate 2, and a mounting position for mounting the sensor on the base plate 11 is located in the area 21. Fig. 9 shows an example in which the mounting plate 2 is designed, and if the mounting box body is welded to the anchor ear 3, the mounting plate 2 may be removed.

As shown in fig. 4 and 5, the upper cover 4 is provided with a plurality of first through holes 41, and each first through hole 41 corresponds to one solar panel 5, and if only one solar panel 5 is provided, only one first through hole 41 may be designed. A set of limiting members is designed around each first through hole 41, the set of limiting members surrounds the first through holes 41, and partial facilities can be shared between the limiting members of adjacent sets. The limiting member is used for fixing the position of the solar panel 5 on the upper cover 4 and preventing the lateral displacement.

The stopper includes a plurality of stoppers distributed in four directions of front, rear, left and right corresponding to the first through holes 41 to surround the first through holes 41, preventing the solar cell panel 5 from sliding in four directions. And, at least one of the stoppers is detachably coupled to the upper cover 4, such that when the solar cell panel is mounted, the transmission line is first passed through the first through hole 41, then the solar cell panel 5 is mounted to the area surrounded by the fixed stoppers, and finally the detachable stoppers are mounted to completely restrict the solar cell panel 5.

In some embodiments, the stop is bent in at least two directions towards the first through hole 41, so that the solar panel 5 can be fastened to the upper cover 4 better. Also, the detachable stopper may be designed to be bent toward the first through hole 41 to catch the solar cell panel 5 at the time of installation. For example, as shown in fig. 4 and 5, the stopper in three directions is designed as a fixed stopper 42, and only one direction of the detachable stopper 43 is designed, and both the fixed stopper 42 and the detachable stopper 43 are bent toward the first through hole 41.

As mentioned above, the facilities of adjacent sets of limiting members can be shared. As shown in fig. 4 and 5, the two sets of stoppers on adjacent sides are designed as detachable stoppers 43 and are designed as a whole to form a fixing block with a T-shaped cross section, and the other stoppers of the two sets of stoppers are designed as fixing stoppers 42 and are bent toward the first through hole 41. In this way, after the two solar panels 5 are mounted, the two solar panels 5 can be fixed simultaneously by the fixing block.

As shown in fig. 6, the solar cell panel 5 may be mounted by being inserted into the upper cover 1, and the region surrounded by the stopper is recessed in the upper cover 4 according to the size of the solar cell panel 5. In this case, the height of each stopper can be reduced correspondingly, and in the extreme case, can be reduced to 0, leaving only the bent portion. The height of the recess is preferably not higher than the thickness of the solar panel 5, otherwise water is easily accumulated.

The part of the upper cover 4 for mounting the solar panel 5 (the first through hole 41, the limiting member, or even the concave structure) can be directly copied to the side plate of the case 1, so that the solar panel 5 can be placed on the side plate.

In view of outdoor weather, accumulated water has a serious influence on the measurement result of the sensor, and in order to avoid the problem, as shown in fig. 3, the bottom edge of the bottom plate 11 is designed to be convex, that is, the edge of the bottom plate 11 is provided with a flange 12 which is slightly higher than other positions of the bottom surface of the bottom plate 11, so that rainwater cannot flow into the middle of the bottom surface, and the sensor cannot be shielded.
