Description

Technical Field

[0001] This utility model relates to the technical field of fire emergency lighting, and in particular to a power supply fixing device for fire emergency lighting fixtures. Background Technology

[0002] Fire emergency lighting is a device used for emergency lighting and has important applications in firefighting. It is commonly used in nighttime operations, power outages, and complex environments. The most common type of fire emergency lighting is the drone emergency lighting, which uses a drone to carry the lighting fixture. The drone hovers at a high altitude, and the fixture is connected to a mobile power source on the ground via a connecting cable, thus illuminating a large area and facilitating firefighting operations. However, before using the drone lighting fixture, a power supply fixing device is needed to secure the mobile power source. In the prior art, utility model patent application number 201520647898.1 discloses a power supply fixing device for fire emergency lighting fixtures, which mainly consists of a power supply box and fixing components. In use, the power supply is placed in the power supply box and then fixed by the fixing components. However, this device has the following problems in use: at some natural disaster sites, the ground is sometimes wet, and the aforementioned device cannot adjust the height of the power supply or keep it away from the wet environment, resulting in high limitations in use, inconvenience, and poor practicality. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a power supply fixing device for fire emergency lighting fixtures that can keep the power supply away from the damp environment of the ground when clamping and fixing the power supply, ensuring the normal use of the power supply, and is convenient to use, reliable and practical.

[0004] This utility model discloses a power supply fixing device for fire emergency lighting fixtures, comprising a mobile vehicle and multiple support plates, all mounted on the upper end of the mobile vehicle; it also includes a lifting mechanism and a clamping mechanism, the clamping mechanism being mounted on the multiple support plates and having a clamping and fixing function; the clamping mechanism is mounted on the lifting mechanism, which is used to lift and lower the clamping mechanism; when it is necessary to fix the power supply of a drone lighting fixture, firstly, the power module is placed on the clamping mechanism and fixed, then one end of the wire is connected to the power supply, and the other end of the wire is plugged into the drone lighting fixture, so that the drone lighting fixture is connected to the power supply through the wire; then, the lifting mechanism causes the clamping mechanism to lift the power supply to a certain height, keeping the power supply away from the damp environment of the ground, ensuring normal use of the power supply; it is convenient to use, reliable, and practical.

[0005] Preferably, the lifting mechanism includes a waterproof hydraulic cylinder and a push rod. The waterproof hydraulic cylinder is fixedly installed on the upper end of the mobile vehicle, and the lower end of the push rod is connected to the output end of the waterproof hydraulic cylinder. The clamping mechanism is installed on the upper end of the push rod. After the power supply is placed on the clamping mechanism and clamped and fixed, when it is necessary to move the power supply away from the damp environment on the ground, the waterproof hydraulic cylinder is opened. The waterproof hydraulic cylinder, through the push rod, causes the clamping mechanism to lift the power supply, raising it to a height away from the damp environment on the ground. This facilitates the adjustment of the power supply height.

[0006] Preferably, the clamping mechanism includes a lifting plate, a lead screw, and two sets of clamping plates. The lifting plate is slidably mounted on multiple sets of support plates. The lifting plate is fixedly mounted on the upper end of the push rod. The lead screw is rotatably mounted on the lifting plate. The front and rear parts of the lead screw are respectively provided with external threads in opposite directions. The two sets of clamping plates are screwed to the front and rear parts of the lead screw, and both sets of clamping plates are slidably mounted on the lifting plate. When fixing the mobile power supply for the UAV emergency lighting, the power supply is first placed between the two sets of clamping plates on the upper end of the lifting plate. Then, the lead screw is rotated, and the rotating lead screw brings the two sets of clamping plates closer to each other, thereby making the two sets of clamping plates contact the front and rear ends of the power supply respectively. The power supply is clamped and fixed on the upper end of the lifting plate by the two sets of clamping plates.

[0007] Preferably, it also includes a fixing plate and fastening bolts. The fixing plate is fixedly installed on the lead screw, and the fastening bolts are screwed to the fixing plate. After the power supply is clamped and fixed by the two sets of clamping plates, the fastening bolts are rotated so that one end of the fastening bolts is pressed tightly against the lifting plate. The friction between the fastening bolts and the lifting plate prevents the lead screw from rotating, thereby improving the stability of the power supply clamping.

[0008] Preferably, the device also includes a mounting plate, a vertical plate, a servo motor, and a take-up roller. The mounting plate is fixedly mounted on the lifting plate, the vertical plate is fixedly mounted on the mounting plate, the servo motor is fixedly mounted on the vertical plate, and the take-up roller is rotatably mounted on the vertical plate. The input end of the take-up roller is connected to the servo motor. After the drone lighting is completed, the drone is first lowered. Then, the power cord connecting the lighting fixture on the drone to the power source is disconnected from both the power source and the drone. Next, one end of the power cord is wound around the take-up roller. Then, the servo motor is turned on, and the servo motor drives the take-up roller to rotate. The rotating take-up roller winds up the power cord, facilitating the winding of the power cord.

[0009] Preferably, it also includes a rain cover, which is fixedly installed on the upper part of the multiple support plates; by shielding the lifting plate with the rain cover, raindrops are prevented from falling onto the power supply at the upper part of the lifting plate during rain, thus ensuring the normal use of the power supply.

[0018] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0019] Example 1

[0020] like Figures 1 to 5The power supply fixing device for the fire emergency lighting fixture of this utility model includes a mobile vehicle 1, multiple support plates 2, a lifting mechanism, and a clamping mechanism. The multiple support plates 2 are all installed on the upper end of the mobile vehicle 1. The clamping mechanism is installed on the multiple support plates 2 and has the function of clamping and fixing. The clamping mechanism is installed on the lifting mechanism, which is used to lift and lower the clamping mechanism. When it is necessary to fix the power supply of the drone lighting, the power module is first placed on the clamping mechanism and fixed. Then, one end of the wire is connected to the power supply, and the other end of the wire is plugged into the drone lighting, so that the drone lighting is connected to the power supply through the wire. Then, the lifting mechanism drives the clamping mechanism to lift the power supply to a certain height, keeping the power supply away from the damp environment of the ground, ensuring the normal use of the power supply. It is convenient to use and has high reliability and practicality.

[0021] like Figure 1 and Figure 4 The lifting mechanism includes a waterproof hydraulic cylinder 3 and a push rod 4. The waterproof hydraulic cylinder 3 is fixedly installed on the upper end of the mobile vehicle 1, and the lower end of the push rod 4 is connected to the output end of the waterproof hydraulic cylinder 3. The clamping mechanism is installed on the upper end of the push rod 4. After the power supply is placed on the clamping mechanism and clamped and fixed, when it is necessary to move the power supply away from the damp environment on the ground, the waterproof hydraulic cylinder 3 is opened. The waterproof hydraulic cylinder 3, through the push rod 4, causes the clamping mechanism to lift the power supply, raising it to a height away from the damp environment on the ground. This facilitates the adjustment of the power supply height.

[0022] like Figure 3 The clamping mechanism includes a lifting plate 5, a lead screw 6, and two sets of clamping plates 7. The lifting plate 5 is slidably mounted on multiple sets of support plates 2. The lifting plate 5 is fixedly mounted on the upper end of the push rod 4. The lead screw 6 is rotatably mounted on the lifting plate 5. The front and rear parts of the lead screw 6 are respectively provided with external threads in opposite directions. The two sets of clamping plates 7 are respectively screwed to the front and rear parts of the lead screw 6. Both sets of clamping plates 7 are slidably mounted on the lifting plate 5. When fixing the mobile power supply for the UAV emergency lighting, the power supply is first placed between the two sets of clamping plates 7 at the upper end of the lifting plate 5. Then, the lead screw 6 is rotated. The rotating lead screw 6 brings the two sets of clamping plates 7 closer to each other, so that the two sets of clamping plates 7 contact the front and rear ends of the power supply respectively. The power supply is clamped and fixed to the upper end of the lifting plate 5 by the two sets of clamping plates 7.

[0023] like Figure 1 , Figure 3 and Figure 5 It also includes a fixing plate 8 and a fastening bolt 9. The fixing plate 8 is fixedly installed on the lead screw 6, and the fastening bolt 9 is screwed to the fixing plate 8. After the power supply is clamped and fixed by the two sets of clamping plates 7, the fastening bolt 9 is rotated so that one end of the fastening bolt 9 is pressed against the lifting plate 5. The friction between the fastening bolt 9 and the lifting plate 5 increases the resistance when the lead screw 6 rotates, prevents the lead screw 6 from rotating on its own, and improves the stability of clamping the power supply.

[0024] like Figure 3 It also includes a mounting plate 10, a vertical plate 11, a servo motor 12, and a take-up roller 13. The mounting plate 10 is fixedly mounted on the lifting plate 5, the vertical plate 11 is fixedly mounted on the mounting plate 10, the servo motor 12 is fixedly mounted on the vertical plate 11, and the take-up roller 13 is rotatably mounted on the vertical plate 11. The input end of the take-up roller 13 is connected to the servo motor 12. After the drone lighting is completed, the drone is first lowered. Then, the power cord connecting the lighting fixture on the drone to the power supply and the drone is unplugged. Then, one end of the power cord is wound around the take-up roller 13. Then, the servo motor 12 is turned on, and the servo motor 12 drives the take-up roller 13 to rotate. The rotating take-up roller 13 winds up the power cord, which facilitates the winding of the power cord.

[0025] like Figure 1 It also includes a rain cover 14, which is fixedly installed on the upper end of multiple support plates 2. By shielding the lifting plate 5 with the rain cover 14, raindrops are prevented from falling onto the power supply at the upper end of the lifting plate 5 during rain, thus ensuring the normal use of the power supply.

[0026] Example 2

[0027] like Figure 1 Based on Embodiment 1, a protective railing 15 is provided at the upper end of the lifting plate 5. The protective railing 15 is fixedly installed at the upper end of the lifting plate 5. When the power supply is placed and fixed at the upper end of the lifting plate 5, the protective railing 15 protects the power supply, reduces external collisions with the power supply, and improves the reliability of the power supply during use.

[0028] The waterproof hydraulic cylinder 3, lead screw 6, fastening bolt 9, servo motor 12, winding roller 13, and rain cover 14 of the power supply fixing device of the fire emergency lighting fixture of this utility model are all purchased from the market. Technical personnel in this industry only need to install and operate it according to the accompanying instruction manual, without requiring any creative work from technical personnel in this field.
