Description

Technical Field

[0001] This invention relates to the technical field of power connection in building construction, specifically a safe power connection device for building construction. Background Technology

[0002] Building construction refers to the production activities during the implementation phase of engineering construction. It is the process of building various buildings. In the construction scenario, the high-frequency use of some electric equipment requires temporary power connection devices to provide power. Its safety and stability directly affect construction efficiency and personnel safety.

[0003] As disclosed in CN213242940U, an outdoor safety power connector for building construction is described. It includes a protective shell, a base rotatably connected to the side wall of the protective shell, multiple grooves on the side wall of the base, a socket on the bottom side wall of each groove, and multiple mounting holes on the side wall of the base. A protective device is embedded within each mounting hole, and the protective device includes a connecting tube embedded in the mounting hole. A first tension spring is fixedly connected to the bottom side wall of the connecting tube. This device reduces the ingress of dust and impurities, extends the service life of the power connector, and prevents the risk of leakage, thus providing good protection for the power connection.

[0004] As disclosed in CN117080802A, a power connection device includes a socket and a plug. A power moving block is movably disposed within the socket. The power moving block is made of insulating material and has a conductive groove on its front side, within which a first conductive layer is disposed. The first conductive layer is connected to a power line via a flexible power cord. A conductive socket is provided on the front side of the socket, corresponding to the conductive groove. The plug is made of insulating material and has a conductive protrusion on its rear side corresponding to the conductive groove. A second conductive layer is disposed on the outer surface of the conductive protrusion. The second conductive layer is connected to the power cord of the appliance. The plug and the socket are detachably fastened together by a clamping device. This device offers advantages such as high safety, high reliability, and the prevention of high-voltage arcing.

[0005] However, based on current power connection devices and their application scenarios, the following shortcomings still exist:

[0006] 1. Existing power connection devices typically have fixed installation positions and directions for the power supply. However, construction scenarios are complex and changeable, often requiring changes to the position and direction of the equipment, necessitating reconnection to the power supply, which is cumbersome.

[0007] 2. Existing power connection devices are not waterproof and dustproof: The construction environment is often accompanied by dust, cement slurry, rainwater or construction water, which can easily cause short circuits in the internal circuit due to dust accumulation or liquid seepage, resulting in tripping, etc.

[0008] 3. Existing power connection devices lack or are inadequate in terms of preventing accidental contact and preventing detachment: When construction personnel move equipment, the power cord is easily pulled, causing the plug and socket to accidentally detach, resulting in sudden equipment stoppage and interruption of the construction process.

[0009] Therefore, we propose a safe power connection device for building construction to solve the problems mentioned above. Summary of the Invention

[0010] The purpose of this invention is to provide a safe power connection device for building construction, to solve the problems mentioned in the background art, where the installation position and direction of the power supply are usually fixed, while the construction environment is complex and changeable, often requiring changes in the position and direction of the equipment, necessitating reconnection to the power supply, which is cumbersome.

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Please see Figures 1-13 The present invention provides the following technical solution:

[0051] To address the issues in existing technologies where the installation location and direction of power supplies are usually fixed, while construction environments are complex and changeable, often requiring changes to the location and direction of the equipment, necessitating reconnection to the power supply, which is cumbersome, and where waterproofing and dustproofing are insufficient (construction environments often involve dust, cement slurry, rainwater, or construction water, which can easily cause short circuits in the internal circuits due to dust accumulation or liquid seepage, leading to tripping), and where anti-accidental contact and anti-detachment designs are lacking or inadequate (when construction personnel move equipment, the power cord can be pulled, causing the plug to accidentally detach from the socket, resulting in sudden equipment shutdown and interruption of the construction process);

[0052] Therefore, the present invention provides a safe power connection device for building construction through the following technical solution: a power assembly consisting of a power socket shell 1, a power socket body 2, a power plug 3, and a protective cover 4; a positioning component, a cable stabilizing component, an overload protection component, and a sealing and locking component. These components work together to ensure safe connection and prevent detachment of the power assembly. The positioning component is located at the end of the power socket shell 1 furthest from the protective cover 4, used to adjust the position and orientation of the power assembly. The cable stabilizing component is located at the end of the protective cover 4 furthest from the power socket shell 1, used to seal the cable between the cable and the protective cover 4. The overload protection component integrates four protections: overload, overvoltage, overtemperature, and surge, with intelligent detection and audible / visual alarm linkage. The sealing and locking component seals and locks the protective cover 4 and the power socket shell 1 after the power assembly is connected.

[0053] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the installation positioning assembly consists of a mounting back plate 5 located on the side of the power socket housing 1 away from the protective cover 4, movable connecting sleeves 6 fixed to the upper and lower ends of the left side of the mounting back plate 5, an annular mounting bracket 7, a locking element for limiting the position, and movable connecting rods 10, fixing caps 11, and anti-slip rubber rings 12 located on the front and rear sides of the mounting back plate 5. First, the mounting bracket 7 is fixed to the support frame at the construction site using bolts. Then, the height and direction of the power assembly are adjusted appropriately according to the equipment and the site conditions. By pulling the mounting back plate 5, the movable connecting sleeves 6 and the mounting bracket 7 slide, thereby changing the direction of the power assembly so that the cable faces the equipment, preventing bending and knotting during use. After adjustment, the locking element is positioned on the side away from the protective cover 4, and the mounting back plate 5 moves the movable connecting sleeves 6 to the mounting bracket 7. The outer side of the mounting bracket 7 forms a sliding structure. The locking components include a mounting bolt 8 threadedly connected to the middle of the movable connecting sleeve 6 and an anti-slip rubber block 9 fixed to the right end of the mounting bolt 8. By rotating the mounting bolt 8, the anti-slip rubber block 9 is pressed against the inner side of the mounting bracket 7, thereby facilitating the limiting of the movable connecting sleeve 6 and the mounting bracket 7. Then, by pulling the power socket housing 1 up or down, the power socket housing 1 moves up and down in the middle of the mounting back plate 5, and the usage height of the power assembly is adjusted appropriately. The power socket housing 1 also drives the movable connecting rod 10 to move up and down on both sides of the mounting back plate 5. After the height adjustment is completed, by rotating the fixing cap 11 threadedly connected to the outer surface of the movable connecting rod 10, the anti-slip rubber ring 12 is tightly fitted between the mounting back plate 5 and the fixing cap 11, thereby limiting the limiting of the mounting back plate 5 and the movable connecting rod 10 and fixing the power socket housing 1.

[0054] like Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, the cable stabilizing assembly includes a sealing limiting cylinder 15 fixed in the middle of the side of the protective cover 4 away from the power socket housing 1, and several sealing rings 16 fixed inside the sealing limiting cylinder 15. The sealing rings 16 tightly wrap around the outside of the cable. The cable is used to connect the power plug 3 to the device. At the same time, a sealing strip 13 is provided on the left side of the power plug 3. The sealing strip 13 is tightly fitted between the power plug 3 and the power socket body 2. A pressure rod 14 for support and fixation is provided between the power plug 3 and the protective cover 4. The cable stabilizing assembly facilitates the sealing connection between the cable and the protective cover 4, achieving a good dustproof and waterproof effect. When the power plug 3 and the power socket body 2 are plugged in, the sealing strip 13 is fitted between the power plug 3 and the power socket body 2, improving the anti-slip and tightness of the connection. Combined with the pressure rod 14, the tightness of the connection between the power plug 3 and the protective cover 4 can be improved.

[0055] like Figure 7 , Figure 8 , Figure 11 , Figure 12 and Figure 13 As shown, the sealing and protective locking assembly includes fixing blocks 17 fixed to the front and rear ends of the power socket housing 1, fixing posts 18 fixed to the front and rear ends of the protective cover 4, a spring 20 disposed inside the fixing blocks 17, a movable pin 21 telescopically connected inside the fixing blocks 17 and connected to the movable end of the spring 20, an insulating rod 22 fixed to the upper end of the movable pin 21, and a sealing gasket 24 tightly fitted between the power socket housing 1 and the protective cover 4. The fixing posts 18 have fixing grooves 19 on their sides, and the sides of the movable pin 21 fit with the sides of the fixing posts 18. The movable pin 21 forms an elastic structure within the fixing blocks 17. The protective cover 4 is engaged at the right end of the power socket housing 1, and the sealing gasket 24 is fitted between the protective cover 4 and the power socket housing 1, improving the sealing at the connection point. The power plug 3 is then inserted into the... In the power socket body 2, the fixing post 18 is inserted into the fixing block 17. The fixing post 18 presses the movable pin 21, causing the movable pin 21 to slide and extend within the fixing block 17. The movable pin 21 presses the spring 20, causing the spring 20 to undergo elastic deformation. When the fixing post 18 is fully inserted into the fixing block 17, that is, when the protective cover 4 is fully engaged with the right end of the power socket housing 1, the spring 20 returns to its elastic deformation, pushing the movable pin 21 into the fixing groove 19, thereby limiting the position between the fixing post 18 and the fixing block 17, that is, automatically locking the protective cover 4 and the power socket housing 1. Then, by rotating the fixing bolt 23, the fixing post 18 and the fixing block 17 are further locked and limited to prevent separation, thus improving the tightness of the connection between the protective cover 4 and the power socket housing 1.

[0056] In addition, the overload protection components include an intelligent protection module located inside the socket housing, a current detection unit, a voltage detection unit, and a temperature detection unit electrically connected to the intelligent protection module, as well as an audible and visual alarm unit and a reset button located on the outer wall of the socket housing. The intelligent protection module has a built-in microcontroller chip, and the temperature detection unit uses an NTC thermistor and is set close to the outer wall of the conductive slot. When the current detection unit detects that the current exceeds 1.2 times the rated value, the voltage detection unit detects that the voltage fluctuation exceeds ±15%, or the temperature detection unit detects that the temperature of the conductive slot exceeds 80°C, the intelligent protection module cuts off the circuit and triggers the audible and visual alarm unit. The audible and visual alarm unit consists of a buzzer and an alarm light. The buzzer sounds an alarm, and the alarm light flashes to alert relevant personnel. Pressing the reset button triggers the reset button. The button can restore circuit connectivity after troubleshooting. The power socket housing 1 is also equipped with a surge protection module inside, which is connected in series with the conductive slot. The outer wall of the surge protection module is equipped with an overheat fuse. The outer peripheral wall of the conductive pin on the left side of the power plug 3 is successively equipped with a copper-plated base layer, a nickel-plated transition layer, and a gold-plated wear-resistant layer. The surge protection module is connected in series with the conductive slot, and the maximum current capacity of the surge protection module is not less than 20kA. The outer wall of the surge protection module is equipped with an overheat fuse. When the temperature of the surge protection module exceeds 120℃, the overheat fuse will automatically melt and cut off the connection between the surge protection module and the circuit. The housings of the power socket 1, the power socket body 2, and the power plug 3 are all made of flame-retardant ABS+PC alloy material, which can play a certain flame-retardant role.
