Description

Technical Field

[0001] The present invention relates to the technical field of power supply devices, and in particular to an intelligent power supply device for construction sites. Background Art

[0002] In the prior art, there is an electrical box for construction sites with application number "201621290922.1", which includes a distribution box body and a distribution box base, wherein the distribution box body is mounted on the distribution box base, a hook is fixedly connected to the distribution box base, and a handle and a winding column are respectively provided on the distribution box base; pendants are integrally connected to the four end corners of the distribution box body, and an industrial waterproof socket is provided between the pendants at the upper and lower ends; electrical control elements are also installed inside the distribution box body, and the electrical control elements include a circuit breaker, a shunt coil and an intermediate relay, and the circuit breaker, the shunt coil, the intermediate relay and the waterproof socket are all electrically connected through a circuit; the electrical box for construction sites is easy to install, can effectively improve the waterproof performance of waterproof plugs and sockets, and facilitate the management of power cords and electricity safety.

[0003] However, it still has obvious defects during use: 1. In actual construction sites, there are often many devices that need to be powered and their locations are not uniform. The power supply device needs to be able to accept socket connections from all directions at the same time. The industrial waterproof sockets in the above device are symmetrically arranged at both ends, which are mainly suitable for power supply to devices on both sides. The wires connected in other directions have to be bent and wound, which can easily cause the insulation layer on the outside of the wires to wear and fall off after long-term use, posing a safety hazard of electric shock; 2. On the construction site, temporary power supply is frequently required due to the complexity of construction. The above device is inconvenient to move, which is very laborious and time-consuming when the place of use is changed many times; 3. The above device does not have a shock-absorbing function. During the moving process, it is very easy to cause the socket and the strip to be loosely connected due to shaking, and there is a disadvantage of mutual separation and loss of power supply, which affects the construction progress; 4. The above device lacks a heat dissipation device. The power supply device is a frequently used equipment on the construction site and has a long working time. It is very easy to accumulate heat inside. If the heat is not dissipated and ventilated in time, the service life of the internal electrical components will be affected. Summary of the invention

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.

[0026] See also Figure 1-3 , the present invention provides a technical solution:

[0027] A smart power supply device for a construction site includes a box body 1. Air outlets 2 are symmetrically provided on the side walls of the box body 1. The air outlets 2 are arranged at the upper end to facilitate the timely discharge of hot air. A plurality of mounting grooves 3 are penetrated through the side walls of the box body 1. A solar panel 4 is provided on the outer side of the top wall of the box body 1. The solar panel 4 can convert solar energy into electrical energy, thereby reducing the consumption of industrial electricity on the construction site and reducing the construction cost. The side of the solar panel 4 is tilted downward. This arrangement is to provide non-contact shielding for the air outlet 2 to prevent water from entering the interior of the box body 1 from the air outlet 2 during rainy and snowy weather. A conductive column 5 is provided in the inner cavity of the box body 1. The conductive column 5 is electrically connected to the solar panel 4 through a conversion wire 6. The solar panel 4 can directly supply power to the conductive column 5. A hollow rotating plate 7 is provided at the upper and lower ends of the mounting groove 3 through a bearing member for rotation connection. The hollow rotating plate 7 can rotate 360 ​​degrees. 7 is provided with a conductive rotating ring 9, which is movably sleeved on the conductive column 5. The conductive rotating ring 9 can conduct the current on the conductive column 5. A conductive rod 10 is fixedly provided on the conductive rotating ring 9. The conductive rod 10 penetrates the side wall of the hollow rotating plate 7 and is connected with a connecting wire 11. The connecting wire 11 is electrically connected with an industrial waterproof socket 12. The construction tools on the construction site can be powered by directly connecting the plug to the industrial waterproof socket 12. A battery 14 is provided at the bottom of the inner cavity of the box 1. The battery 14 is electrically connected to the conductive column 5. A charging wire 15 is electrically connected to the battery 14. The charging wire 15 penetrates the side wall of the box 1 and is connected with a waterproof plug 16. The waterproof plug 16 is used to connect an external power supply to the battery 14 for energy storage and power supply. It is mainly used in situations where there is insufficient light and the solar panel 4 does not convert enough electricity.

[0028] The bottom of the box body 1 is connected to the bottom plate 20 through a large shock-absorbing spring 19. The large shock-absorbing spring 19 has elasticity. An air inlet pipe 21 is symmetrically arranged on one side of the bottom plate 20 close to the box body 1. In order to keep the inside of the box body 1 clean and tidy, a dust filter can also be arranged at the entrance of the air inlet pipe 21. The air inlet pipe 21 is connected with an action pipe 22 and an air outlet pipe 23. An air inlet 24 is opened on one side of the bottom wall of the box body 1 close to the air outlet pipe 23. The air outlet pipe 23 is connected to the air inlet 24. A one-way valve 25 is arranged in the air outlet pipe 23. The setting of the one-way valve 25 makes The wind can only flow from the air outlet pipe 23 to the air inlet 24, but not reverse flow. A slide plate 26 is movably provided in the action pipe 22, and the slide plate 26 can move up and down in the inner wall of the action pipe 22. The slide plate 26 is connected to the outer side of the bottom wall of the box body 1 through an upper shock-absorbing spring 27. A limit block 29 is fixedly provided on the inner wall of the action pipe 22 away from the box body 1. A lower shock-absorbing spring 30 is connected between the slide plate 26 and the limit block 29. A one-way valve 31 is provided in the air inlet pipe 21. The setting of the one-way valve 31 makes it possible for wind to only flow into the air inlet pipe 21 from the outside, but not reverse flow.

[0029] The bottom of the box body 1 is symmetrically fixed with support columns 34, on which a rotating shaft 35 is movably hinged, and a universal wheel 36 is fixedly provided through the rotating shaft 35. The arrangement of the universal wheel 36 allows the device to be easily moved to various places where it is needed, saving time and effort.

[0030] As a preference, an insulating layer 8 is provided on the outer side of the hollow rotating plate 7. The provision of the insulating layer 8 can improve the isolation effect on the electric current and prevent workers from getting electric shock.

[0031] As a preferred embodiment, a plurality of groups of limit blocks 13 are fixedly provided on the outer side of the box body 1 . The limit blocks 13 are arranged below the hollow rotating plate 7 . The limit blocks 13 mainly limit the position of the hollow rotating plate 7 .

[0032] As a preferred embodiment, a hanging block 17 is fixedly provided on the outer wall of the box body 1, and a card slot 18 is opened on the hanging block 17. The charging cable 15 is embedded in the card slot 18. When not in use, the charging cable 15 can be embedded in the card slot 18, which is neat and beautiful, and also avoids the waterproof plug 16 being placed on the ground at will, so that the waterproof plug 16 is damaged by friction with the ground when the box body 1 is moved.

[0033] As a preferred embodiment, a blocking block 28 is fixedly provided on the inner side wall of the action tube 22 close to the box body 1, and the function of the blocking block 28 is to prevent the slide plate 26 from detaching from the action tube 22 during movement.

[0034] As a preference, an auxiliary shock-absorbing spring 32 is connected between the outer wall of the air inlet duct 21 and the outer side of the bottom wall of the box body 1. The provision of the auxiliary shock-absorbing spring 32 increases the support for both sides of the bottom of the box body 1, thereby improving the stability of the box body 1.

[0035] As a preferred embodiment, a side guide plate 33 is symmetrically fixedly provided on one side of the bottom plate 20 close to the box body 1, and the bottom side wall of the box body 1 is movably provided between the side guide plates 33. The side guide plates 33 guide and limit the moving direction of the box body 1 during vibration, so that the box body 1 is more stable.

[0036] Working principle: When the devices on the construction site in different directions need to draw electricity, an idle industrial waterproof socket 12 can be selected. The hollow rotating plate 7 can be rotated by the connecting wire 11 on the industrial waterproof socket 12, so that the industrial waterproof socket 12 and the connecting wire 11 are rotated to the same position as the power-drawing tool to avoid the bending and entanglement of the wires causing wear and falling of the external insulation. Then the plug of the power-drawing tool can be inserted into the industrial waterproof socket 12 for use. At this time, since the conductive rod 10 and the hollow rotating plate 7 are fixedly arranged, the connecting wire 11 drives the hollow rotating plate 7 to rotate through the conductive rod 10, and the conductive rod 10 also drives the conductive rotating ring 9 to rotate around the conductive column 5 to conduct electricity. The electric energy of the conductive column 5 comes from the input after the solar panel 4 converts sunlight into electric energy through the conversion wire 6, and from the electric energy stored in the battery 14 charged from the outside through the waterproof plug 16. When the sun is sufficient, only the former can be used for power supply, and when the light is weak, the two can assist in power supply.

[0037] In order to meet the need for temporary power supply at multiple locations on the construction site, the device can be conveniently moved to various places where it is needed through the universal wheels 36 at the bottom of the box 1. During the movement, since the ground on the construction site is often uneven, the box 1 will be bumpy, and the large shock-absorbing spring 19 can buffer and reduce shock. In addition, the upper shock-absorbing spring 27 and the lower shock-absorbing spring 30 will also shake up and down, thereby driving the slide plate 26 to move up and down. Under the action of the one-way valve 1 25 and the one-way valve 2 31, when the slide plate 26 moves up, wind enters the air inlet pipe 21 from the outside. When the slide plate 26 descends, wind is pushed into the air inlet 24 from the air inlet pipe 21 and the air outlet pipe 23, thereby cooling the electrical components inside the box 1. Finally, the hot air is discharged from the air outlet 2 at the upper end of the box 1, completing the gas exchange, accelerating ventilation, and preventing internal components from overheating and causing damage.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
