[0031] A first cover plate 9 is arranged on the top of the first battery box 6 and used for closing the first battery box 6 to prevent the first battery 7 from being interfered by the external environment. A second cover plate 14 is arranged on the top of the shell 2 and used in cooperation with the first cover plate 9, the second cover plate 14 is arranged in cooperation with the shell 2 and used for closing the first battery box 6 and the second battery box 11 in the shell 2 to protect the batteries and the circuit board 10.

[0032] In order to fix the device, a mounting plate 1 is clamped on the top of the shell 2 through a clamping mechanism, and the mounting plate 1 is fixed on the equipment mounting position through bolts. The first cover plate 9 and the second cover plate 14 are located between the shell 2 and the mounting plate 1, and the mounting plate 1 further fixes the first cover plate 9 and the second cover plate 14, thereby enhancing the stability of the whole structure.

[0033] In addition, at least two extension strips 16 are fixed on one end of the second cover plate 14 close to the first battery box 6, and a first insertion hole 8 corresponding to the extension strip 16 is arranged on one side of the first battery box 6. When the second cover plate 14 is covered on the shell 2, the extension strip 16 is plugged in the first insertion hole 8, thereby further enhancing the connection strength between the second cover plate 14 and the shell 2. Meanwhile, the bottom of the first cover plate 9 is in contact with the extension strip 16, thereby fixing the second cover plate 14 and preventing the second cover plate 14 from loosening.

[0034] In order to further fix the second cover plate 14, the top of the extension strip 16 is provided with a positioning hole 17, and a pin 19 is inserted into the positioning hole 17. The bottom of the first cover plate 9 is provided with a clearance groove 18 corresponding to the extension strip 16, and the top end of the pin 19 is fixedly arranged at the bottom of the clearance groove 18. When the first cover plate 9 is covered on the first battery box 6, the pin 19 is inserted into the positioning hole 17, and the second cover plate 14 is further fixed, thereby enhancing the stability and reliability of the whole structure.

[0035] The specific structure of the clamping mechanism is as follows: two support seats 3 are fixedly arranged at the top of the shell 2, and the top of the mounting plate 1 is provided with nut seats 27 located on both sides of the shell 2.

When the conical head 26 pushes the insertion rod 22 to move, the spring 23 is compressed; when the conical head 26 moves away, the spring 23 pushes the sliding seat 20 and the insertion rod 22 to reset.

[0038] Embodiment 2: Reference Figures 1-5 On the basis of Embodiment 1, improvements are made: in order to prevent the connection line 4 from falling off the circuit board 10, two recesses 13 corresponding to the connection line 4 are arranged at one end of the shell 2, and a resisting strip 15 corresponding to the recess 13 is fixedly arranged at the bottom of the second cover plate 14. When the second cover plate 14 is covered on the shell 2, the resisting strip 15 is resisted in the recess 13, so that the connection line 4 is fixed in the recess 13, thereby preventing the connection line 4 from loosening or falling off.

[0039] In addition, the end of the insertion rod 22 close to the support seat 3 is provided with a tapered portion, and the support seat 3 is fixed on the mounting plate 1 by using the inclined surface. When the insertion rod 22 is inserted into the second insertion hole 24, the tapered portion is resisted on the hole wall of the second insertion hole 24 and generates extrusion force, so that the insertion rod 22 is more firmly inserted into the second insertion hole 24.

[0040] In order to facilitate the rotation of the stud 25, the top of the stud 25 is provided with a cross slot matched with the screwdriver. When the screwdriver is needed to rotate the stud 25, the head of the screwdriver is inserted into the cross slot to operate.

[0041] In the application, during the installation, firstly, the battery one 7 is placed in the first insertion hole 8, and the battery two 12 is placed in the second battery box 11, then the second cover plate 14 is inserted on the mounting plate 1, and the abutting strip 15 is matched with the groove 13 to fix the connecting wire 4, until the extension strip 16 is inserted into the corresponding first insertion hole 8, then the first cover plate 9 is covered in the first battery box 6, and during the covering process, the gap slot 18 is clamped on the extension strip 16, and the pin column 19 is inserted into the positioning hole 17, which can fix the second cover plate 14;

[0042] Then the mounting plate 1 is installed on the installation area through the bolt, the shell 2 after the installation is placed on the mounting plate 1, the second cover plate 14 and the first cover plate 9 are abutted with the mounting plate 1, and the support seat 3 is matched with the insertion rod 22, finally the stud 25 is rotated, the stud 25 moves downward in the nut seat 27, the downward movement of the stud 25 can drive the conical head 26 to move downward, the downward movement of the conical head 26 can push the two insertion rods 22 away from each other, which can drive the insertion rod 22 to be inserted into the second insertion hole 24 on the corresponding side, so as to fix the support seat 3, when the stud 25 is moved upward by reversing the rotation, the insertion rod 22 can be separated from the second insertion hole 24 under the action of the spring 23, and the fixation of the support seat 3 is released;

[0043] When working, the battery one 7 is powered on, and the voltage is converted to 3.3V through the circuit board 10 for load power supply and charging of the battery two 12. The voltage of the battery two 12, the voltage after the voltage conversion and the working voltage required by the output voltage circuit are consistent, all of which are 3.3V. When the wireless module is transmitting, the battery two 12 plays the role of power supply, and together with the power supply after the voltage conversion, it supplies power to the load. Since the battery two 12 can provide a large amount of instantaneous power and has the ability of instantaneous high-power output, the power consumption of the wireless module during transmission mainly comes from the battery two 12, and the output voltage is still 3.3V, which has no effect on other loads. When the circuit works in a low-power consumption state again, the input power charges the battery two 12, ensuring the capacity of the battery two 12.

[0044] However, as known by those skilled in the art, the working principle and wiring method of the circuit board 10 are common, which belong to conventional means or common knowledge, and will not be described here. Those skilled in the art can make any selection according to their needs or convenience.

[0045] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
