Description

Technical Field

[0001] This invention relates to the field of power supply technology, and in particular to a power supply device for safety engineering equipment at construction sites. Background Technology

[0002] Construction site safety engineering refers to a comprehensive practical system that uses systematic management measures and technical means to protect personnel, property, and the environment from harm during construction activities. Construction site safety engineering requires the use of numerous electronic devices, such as electronic monitoring systems and electronic gates. However, construction sites are prone to unexpected power outages, which can directly cause these electronic devices to lose power, rendering them inoperable and preventing or recording accidents. Therefore, to prevent this, construction sites typically install passive power supply systems to provide backup power to the electronic devices during unexpected power outages.

[0003] The backup power unit is installed by housing a large number of batteries in a power cabinet, and then controlling the batteries through a control cabinet to achieve the function of backup power supply. It should be noted that traditional battery compartments are mostly arranged in a rectangular shape, which can lead to uneven heat dissipation and create heat dissipation dead zones. This can cause some batteries to overheat, accelerate aging, or cause safety risks. In addition, traditional battery compartments only rely on cooling fans for directional cooling, which is inefficient. A single cooling method is difficult to handle the simultaneous heating of multiple batteries, and the heat dissipation resources are not allocated reasonably. Furthermore, the traditional rectangular layout makes it difficult to achieve efficient battery arrangement and integration of the cooling system in a limited space, making battery cooling more difficult, and even posing a fire risk if the overheating is severe. Summary of the Invention

[0004] The purpose of this invention is to provide a power supply device for safety engineering equipment at construction sites, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A power supply device for safety engineering equipment at construction sites includes a power cabinet and multiple batteries. The power cabinet is cylindrical with a notch on one side. A side filter is installed at the notch of the power cabinet. A double-headed cooling fan and a cooling mesh for heat dissipation are installed on the top and bottom sides of the power cabinet, respectively. A bracket is installed on the bottom side of the power cabinet. It also includes a rotating horizontal heat dissipation device, which is installed inside the power cabinet, and multiple batteries are installed inside the rotating horizontal heat dissipation device. The rotating horizontal heat dissipation device is used to dissipate heat from the multiple batteries in both longitudinal and lateral directions. The rotating horizontal heat dissipation device includes multiple battery compartments, which are rotatably installed inside the power cabinet. Multiple batteries are installed in the multiple battery compartments respectively. A side heat dissipation box is installed inside the power cabinet. Multiple heat dissipation shafts are rotatably installed inside the side heat dissipation box, and multiple heat dissipation fan blades are installed on the heat dissipation shafts. The rotation of the heat dissipation shafts drives the multiple heat dissipation fan blades to rotate, thereby dissipating heat from the battery compartments in the lateral direction. Two sliding filter plates are slidably installed on both sides of each battery compartment. An active deployment device is installed on the rotating horizontal heat dissipation device, which is used to open the rotating horizontal heat dissipation device. The active deployment device includes multiple splitting and connecting drive frames, which are movably installed in multiple battery compartments.

[0008] Furthermore, in a preferred embodiment of the present invention, a gear ring frame is rotatably mounted on the top inner wall of the power cabinet, and multiple battery compartments are mounted on the gear ring frame; A drive gear is mounted on the main shaft, and the drive gear meshes with the gear ring frame.

[0009] Furthermore, in a preferred embodiment of the present invention, a first extension shaft is installed on the bottom fan shaft of the dual-head cooling fan, and pulleys are installed on both the first extension shaft and the main rotating shaft, with a transmission belt sleeved on the two pulleys.

[0010] Furthermore, in a preferred embodiment of the present invention, the active deployment device further includes a plurality of arc-shaped push plates, which are respectively movably mounted on the bottom side of the plurality of battery compartments; An arc-shaped pad is installed on the bottom inner wall of the power cabinet. The arc-shaped pad is positioned corresponding to the side filter screen. The arc-shaped push plate rotates and contacts the arc-shaped pad, thereby driving the arc-shaped push plate to move upward.

[0011] Furthermore, in a preferred embodiment of the present invention, the splitting and connecting drive frame is mounted on the arc-shaped push plate, and a reset spring is mounted on the arc-shaped push plate, the reset spring being mounted on the bottom side of the battery compartment.

[0012] Furthermore, in a preferred embodiment of the present invention, two mounting shafts are installed on the splitting and connecting rotating rod. One mounting shaft is installed on the inner wall of the battery compartment, and a splitting and connecting drive groove is provided on the sliding filter plate. The other mounting shaft is movably installed in the splitting and connecting drive groove. Two splitting and engaging drive shafts are rotatably mounted on the splitting and engaging drive frame. A linkage groove is provided on the splitting and engaging rotating rod, and the splitting and engaging drive shafts are movably installed in the linkage groove.

[0013] Furthermore, in a preferred embodiment of the present invention, a dust blowing and cleaning device is also included. The dust blowing and cleaning device is installed on the power cabinet and is used to actively clean the surface of the power cabinet. The dust cleaning device includes a rotating cleaning frame, an air collection hood is rotatably mounted on the top side of the power cabinet, the dual-head cooling fan is located inside the air collection hood, and the rotating cleaning frame is mounted on the air collection hood. A bottom cleaning frame is slidably mounted on the rotating cleaning frame, and the bottom cleaning frame is used to clean the heat dissipation mesh.

[0014] Furthermore, in a preferred embodiment of the present invention, a second extension shaft is mounted on the top side fan shaft of the dual-head cooling fan, and the second extension shaft is mounted on the air collection cover; The rotating cleaning frame is hollow and recessed in the middle. Multiple air blowing nozzles are installed in the recessed position of the rotating cleaning frame. An air guide pipe is installed on the rotating cleaning frame and connected to the air collection hood. The gas collection hood has a rotating groove, and a rotating frame is rotatably installed in the rotating groove. The rotating frame is installed on the top side of the power cabinet.

[0015] Furthermore, in a preferred embodiment of the present invention, a vertical groove is provided on one side of the rotating sweeping frame, the bottom sweeping frame is slidably installed in the vertical groove, a vibration spring is installed on the bottom inner wall of the vertical groove, the vibration spring is installed on the bottom sweeping frame, and a vibration block is installed on the bottom sweeping frame. One side of the bottom cleaning frame is arc-shaped, and a compression semi-elliptical block is installed on the bottom side of the power cabinet. The bottom cleaning frame rotates and is squeezed by the compression semi-elliptical block, which is used to drive the bottom cleaning frame to move downward.

[0016] The beneficial effects of the power supply device for construction site safety engineering equipment proposed in this invention are: In this invention, by setting up a rotating lateral heat dissipation device, when the batteries are in use, the radial layout effectively increases the gap between the batteries while ensuring the number of batteries, increasing airflow and improving heat dissipation. In addition, the dual-head cooling fan blows air into the power cabinet to achieve vertical heat dissipation, and allows hot air to be discharged through the heat dissipation mesh. Multiple cooling fan blades blow air at the same rotation speed as the dual-head cooling fan. When the main shaft rotates, it drives the gear ring frame to rotate, which in turn drives multiple battery compartments to rotate to the position of the side filter screen, achieving lateral heat dissipation for multiple batteries. Moreover, through the combination of central heat dissipation and rotating lateral heat dissipation, each battery can obtain uniform heat dissipation, eliminating local hot spots, improving heat dissipation efficiency, extending life, and reducing maintenance costs and replacement frequency.

[0017] Furthermore, in this invention, by setting up an active unfolding device, when the battery compartment rotates to the position of the side filter, the arc-shaped push plate is squeezed by the arc-shaped pad, causing the arc-shaped push plate to move upward. The upward movement of the arc-shaped push plate drives the two opening and closing drive frames to move, and causes the two return springs to be stressed. At the same time, the movement of the opening and closing drive frames drives the two opening and closing rotating rods to rotate through the two opening and closing drive shafts, thereby causing the sliding filter plate to slide and unfold, so that the battery is directly exposed. At this time, when multiple cooling fan blades blow air to dissipate heat at the same speed as the double-headed cooling fan, the heat around the battery can be directly discharged through the side filter, further enhancing the heat dissipation effect. When not dissipating heat, the fan blades are turned off, providing sufficient protection against dust, moisture, and collision.

[0018] Furthermore, in this invention, by setting up a dust-blowing cleaning device, when the dual-head cooling fan is started, the second extension shaft drives the air collection hood to rotate, causing the air collection hood to rotate on the rotating frame via a rotating groove. The rotation of the air collection hood drives the rotating cleaning frame to rotate, and the rotation of the rotating cleaning frame drives the bottom cleaning frame to rotate, actively cleaning the surface of the power cabinet, the side filter screen, and the heat dissipation screen, avoiding the problem of poor heat dissipation caused by dust accumulation. At the same time, the air blown out by the dual-head cooling fan enters the rotating cleaning frame through the air guide pipe, and is finally sprayed onto the surface of the power cabinet through multiple air nozzles, achieving dual cleaning of sweeping and blowing. The vibration block vibrates the bottom side of the power cabinet, avoiding the problem of dust accumulation on the heat dissipation screen and the side filter screen, thereby further ensuring the heat dissipation effect of the battery.

Two sliding filter plates 702 are slidably installed on both sides of the battery compartments 701.

[0029] It should be noted that in this embodiment of the invention, when the battery 2 is in use, the dual-head cooling fan 5 is started to blow air into the power cabinet 1 to dissipate heat, thereby achieving the purpose of heat dissipation in the vertical direction and allowing hot air to be discharged through the heat dissipation mesh 3.

It should be noted that in this embodiment of the invention, when the battery compartment 701 rotates to the position of the side filter screen 4, the multiple sliding filter plates 702 slide and unfold, directly exposing the battery 2. At this time, when the multiple cooling fan blades 706 blow air at the same speed as the double-headed cooling fan 5, the heat around the battery 2 can be directly discharged through the side filter screen 4, further enhancing the heat dissipation effect.

At the same time, the air blown out by the dual-head cooling fan 5 enters into the rotating cleaning frame 901 through the air guide pipe 908, and is finally sprayed onto the surface of the power cabinet 1 through multiple air blowing nozzles 906, realizing dual cleaning of cleaning and blowing, so that the outside of the power cabinet 1 is kept clean, thereby ensuring that the power cabinet 1 itself can maintain effective heat dissipation.

[0039] Please continue to refer to the instruction manual appendix. Figure 3 and Figures 8-10More specifically, in this embodiment of the invention, a vertical slide groove 903 is provided on one side of the rotating sweeping frame 901, and the bottom sweeping frame 902 is slidably installed in the vertical slide groove 903. A vibration spring 904 is installed on the bottom inner wall of the vertical slide groove 903, the vibration spring 904 is installed on the bottom sweeping frame 902, and a vibration block 912 is installed on the bottom sweeping frame 902. Furthermore, one side of the bottom cleaning frame 902 is arc-shaped, and a pressing semi-elliptical block 905 is installed on the bottom side of the power cabinet 1. The bottom cleaning frame 902 rotates and is pressed by the pressing semi-elliptical block 905, which is used to drive the bottom cleaning frame 902 to move downward. It should be noted that, in this embodiment of the invention, the bottom cleaning frame 902 rotates and is pressed by the pressing semi-elliptical block 905, causing the bottom cleaning frame 902 to move downward in the vertical slide 903, and causing the vibration spring 904 to be stressed. Therefore, when the bottom cleaning frame 902 continues to rotate and separates from the pressing semi-elliptical block 905, under the pull force of the vibration spring 904, the bottom cleaning frame 902 is reset and vibrates the bottom side of the power cabinet 1 through the vibration block 912, so as to shake off the accumulated dust on the heat dissipation mesh 3 and the side filter mesh 4.

[0040] In summary, the working principle of the power supply device for construction site safety engineering equipment provided in this embodiment of the invention is as follows: When the battery 2 is in use, the dual-head cooling fan 5 is activated to blow air into the power cabinet 1 for cooling, achieving the purpose of vertical cooling and allowing hot air to be discharged through the heat dissipation mesh 3. At the same time, the activation of the dual-head cooling fan 5 drives a pulley 713 to rotate via the first extension shaft 712. The rotation of one pulley 713 drives another pulley 713 to rotate via the transmission belt 714, which in turn drives the main shaft 707 to rotate. The rotation of the main shaft 707 drives multiple linkage gears 708 to rotate, so that the multiple linkage gears 708 drive multiple heat dissipation devices. The gear 709 rotates, driving the cooling shaft 705 to rotate. The rotation of the cooling shaft 705 drives multiple cooling fan blades 706 to rotate, enabling the multiple cooling fan blades 706 to blow air for heat dissipation at the same speed as the dual-head cooling fan 5. In addition, when the main rotating shaft 707 rotates, it drives the gear ring frame 710 to rotate. The rotation of the gear ring frame 710 drives multiple battery compartments 701 to rotate, causing the battery compartments 701 to rotate to the position of the side filter screen 4, achieving lateral heat dissipation for multiple batteries 2, thereby effectively ensuring the heat dissipation effect of the batteries 2. Furthermore, when the battery compartment 701 rotates to the position of the side filter screen 4, the arc-shaped push plate 807 is pressed by the arc-shaped pad 808, causing the arc-shaped push plate 807 to move upward. The upward movement of the arc-shaped push plate 807 drives the two disengagement drive frames 801 to move, and causes the two return springs 809 to be stressed. At the same time, the movement of the disengagement drive frames 801 drives the two disengagement rotating rods 802 to rotate through the two disengagement drive shafts 805. The disengagement drive shafts 805 slide in the linkage groove 806, and the disengagement rotating rods 802 rotate on a mounting shaft 803. It should be noted that the rotation of the disengagement rotating rods 802 drives the sliding filter plate 702 to slide open through another mounting shaft 803. At the same time, the mounting shaft 803 slides in the linkage groove 806, so that the battery 2 is directly exposed. At this time, when the multiple cooling fan blades 706 blow air at the same speed as the double-headed cooling fan 5, the heat around the battery 2 can be directly discharged through the side filter screen 4, further enhancing the heat dissipation effect. Furthermore, when the dual-head cooling fan 5 starts, the second extension shaft 909 drives the air collection shroud 907 to rotate, causing the air collection shroud 907 to rotate on the rotating frame 911 via the rotating slot 910. The rotation of the air collection shroud 907 drives the rotating cleaning frame 901 to rotate, which in turn drives the bottom cleaning frame 902 to rotate, actively cleaning the surface of the power cabinet 1, the side filter screen 4, and the heat dissipation mesh 3, preventing dust accumulation from causing poor heat dissipation of the power cabinet 1. At the same time, the air blown out by the dual-head cooling fan 5 enters the rotating cleaning frame 901 through the air guide pipe 908, and is finally sprayed onto the surface of the power cabinet 1 through multiple air nozzles 906. The surface of the power cabinet 1 is cleaned by both sweeping and blowing, further ensuring the cleaning effect. In addition, the bottom cleaning frame 902 rotates and is squeezed by the squeezing semi-elliptical block 905, causing the bottom cleaning frame 902 to move downward in the vertical slide 903, and causing the vibration spring 904 to be stressed. Therefore, when the bottom cleaning frame 902 continues to rotate and separates from the squeezing semi-elliptical block 905, the bottom cleaning frame 902 is reset under the pull force of the vibration spring 904 and vibrates the bottom side of the power cabinet 1 through the vibration block 912, avoiding the problem of dust accumulation on the heat dissipation mesh 3 and the side filter mesh 4, thereby further ensuring the heat dissipation effect of the battery 2.
