Description

Technical Field

[0001] This utility model belongs to the field of construction progress monitoring technology, and in particular relates to a construction progress monitoring device. Background Technology

[0002] Construction progress monitoring is a crucial link in ensuring project quality and achieving schedule targets. By monitoring construction dynamics in real time, deviations can be detected promptly, allowing for adjustments and preventing economic losses due to delays. Currently, construction progress monitoring devices are mainly divided into two categories: fixed-point and wearable. Fixed-point monitoring uses a lifting mechanism to install cameras to monitor specific areas, but it can only cover a fixed range and cannot flexibly track the movement of construction workers. Furthermore, the installation and maintenance costs are high. Wearable monitoring involves fixing cameras to safety helmets, which are then carried by construction workers for detailed monitoring. However, existing solutions generally have the following drawbacks:

[0003] Insufficient protection for cameras: Cameras are mostly installed on the top of safety helmets, making them vulnerable to damage from falling objects.

[0004] Weight imbalance: When the cameras are focused in front, the helmet is heavier in the front and lighter in the back, which can cause it to be unstable or even slip off.

[0005] Limited monitoring range: It requires frequent head rotation to adjust the viewing angle, which increases staff fatigue and makes it easy to miss key details.

[0006] Therefore, it is essential to invent a construction progress monitoring device. Utility Model Content

[0007] To address the aforementioned technical problems, this utility model provides a construction progress monitoring device, comprising a safety helmet body, monitoring bases, an insertion port, a back strap power supply, a monitoring camera, a cable routing arc protrusion, a brim, a safety helmet inner support, and binding straps. The safety helmet body has four monitoring bases integrally mounted on it, one of which has an insertion port connected to the back strap power supply. The top of the safety helmet body has a cable routing arc protrusion located above and between the four monitoring bases. The safety helmet body has a brim, inside which a safety helmet inner support is fastened, and binding straps are installed on the inner support.

[0008] Preferably, the power supply for the shoulder strap includes a power box, shoulder straps, chest strap, chest plate, and connecting wires. The power box is connected to one end of each of the two symmetrical shoulder straps and chest straps, and the other end of the shoulder straps and chest straps is connected to the chest plate. The connector of the power box is connected to the socket.

[0009] Preferably, the socket is located at the monitoring seat at the rear of the safety helmet body, and a brim is provided at the front of the safety helmet body. The safety helmet body, monitoring seat, wiring arc protrusion and brim are integrally formed.

[0010] Preferably, the four monitoring seats are located in the front, back, left, and right directions of the main body of the safety helmet. The monitoring seats are inverted "L" shaped structures, and each monitoring seat is equipped with a monitoring camera.

[0011] Preferably, the wiring arc protrusions between the monitoring bases have the necessary channels for wiring, and the guides connect the monitoring cameras on the arc protrusions sequentially through the channels inside the arc protrusions. The power supply box with a power supply on the back provides power to the monitoring cameras.

[0012] Preferably, the shoulder straps and chest straps installed on the power box and chest plate are both made of high-elasticity yarn and are arc-shaped wide straps, with a gap between the two shoulder straps that allows the head to pass through.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention features inverted "L"-shaped monitoring mounts on the front, back, left, and right sides of the safety helmet body, each embedding a monitoring camera. This design provides a 360° field of view without requiring head rotation, reducing operator workload and preventing the top camera from being directly exposed to the risk of falling objects. The top's cable routing arc protrusion has a built-in channel that conceals the camera's connection cable, preventing exposed wear or tangling and improving device reliability.

[0015] The power supply box of this invention is connected to the chest plate via shoulder straps and a chest strap made of high-elastic yarn, which evenly distributes the power supply weight across the shoulders and chest, avoiding the slippage problem caused by concentrated weight on the front of traditional head-mounted devices. The curved wide strap design conforms to ergonomics, reducing the pressure sensation during prolonged wear.

[0016] This invention features cameras evenly distributed symmetrically on all four sides, avoiding the front-heavy problem caused by concentrated weight on the front in traditional designs. This positions the helmet's center of gravity directly above the head, significantly reducing the risk of slippage. The monitoring base is made of lightweight material and integrally molded with the helmet body, further optimizing weight distribution while ensuring structural strength. Combined with the distributed power supply design on the shoulder strap, this forms a dual-balance system of "four-way cameras + shoulder strap counterweight." Attached Figure Description

[0024] As attached Figure 1 To be continued Figure 3 As shown:

[0025] This utility model provides a construction progress monitoring device, including a safety helmet body 1, a monitoring base 2, an insertion port 3, a back strap power supply 4, a monitoring camera 5, a wiring arc protrusion 6, a brim 7, a safety helmet inner support 8, and a binding strap 9. The safety helmet body 1 is integrally provided with four monitoring bases 2, one of which has an insertion port 3 connected to the back strap power supply 4; the top of the safety helmet body 1 is provided with a wiring arc protrusion 6, which is located above and between the four monitoring bases 2; the safety helmet body 1 is provided with a brim 7, and the safety helmet inner support 8 is installed inside the brim with a buckle, and the binding strap 9 is installed on the safety helmet inner support 8.

[0026] Furthermore, the power supply 4 consists of a power box 41, shoulder straps 42, chest strap 43, chest plate 44, and connecting cable 45. The power box 41 is made of lightweight engineering plastic and integrates a rechargeable lithium battery to power the surveillance camera 5. The shoulder straps 42 and chest strap 43 are both woven from high-elastic yarn into a wide, curved shape, providing elastic conformability. One end is symmetrically connected to both sides of the power box 41 via injection-molded buckles, and the other end is symmetrically connected to both sides of the chest plate 44 via injection-molded buckles. The chest plate 44 is a curved ABS plastic plate that conforms to the contours of the human chest and has a non-slip silicone layer on its surface to prevent movement during wear. The connecting cable 45 is a bend-resistant shielded cable. One end is soldered to the circuit board inside the power box 41, and the other end has a waterproof plug that matches the socket 3. The plug connects to the socket 3 on the monitoring base 2 at the rear of the helmet body 1 to achieve stable power transmission. The symmetrical layout of the shoulder straps 42 and chest straps 43 ensures that the weight of the power box 41 is evenly distributed on the shoulders and chest of the human body, avoiding the head imbalance problem caused by traditional head-mounted power supplies.

[0027] Furthermore, the connector 3 is embedded in the bottom of the monitoring base 2 at the rear of the helmet body 1. The monitoring base 2 has an inverted "L" shape. The helmet body 1, monitoring base 2, cable routing arc protrusion 6, and brim 7 are all integrally molded from ABS engineering plastic using injection molding, with no seams between the components and high structural strength. The brim 7 is located at the front of the helmet body 1, with a 15° downward-sloping arc shape and a thickened design, which can effectively block dust falling from high altitudes and direct sunlight, without obstructing the shooting angle of the front monitoring camera 5. The cable routing arc protrusion 6 is a top arc-shaped protrusion structure with a 5mm diameter through-type cable routing channel inside. The two ends of the channel connect to the internal cavities of the four monitoring bases 2 at the front, back, left, and right, respectively, providing a concealed cable routing path for the connecting wires.

[0028] Furthermore, four monitoring seats 2 are symmetrically distributed in the front, back, left, and right directions of the main body 1 of the safety helmet (i.e., directly in front, directly behind, to the left, and to the right). Each monitoring camera 5 uses a 1080P high-definition wide-angle lens, with an explosion-proof PC shell and a scratch-resistant tempered glass covering the lens surface. The horizontal shooting angle can reach 120°, and the vertical shooting angle is 90°, which can collect real-time data on the construction scene in four directions. The "L"-shaped horizontal section of the monitoring seat 2 is slightly tilted downwards by 10° to prevent rainwater from accumulating on the lens surface and to reduce the direct impact of falling objects from heights on the lens.

[0029] Furthermore, the through-channel inside the wiring arc protrusion 6 has a circular cross-section, smooth inner walls, and is lined with anti-wear rubber pads to ensure that the wires extend through the channel to the mounting holes of the four monitoring bases 2 at the front, back, left, and right. The power and data cables of each monitoring camera 5 are connected in parallel with the main cable inside the wiring arc protrusion 6 via flexible ribbon cables. The end of the main cable is connected to the socket 3, which connects to the connector 45 of the power supply cable 4. This design achieves centralized power supply and data transmission for multiple cameras 5, with the wiring concealed entirely inside the safety helmet body 1, avoiding the risk of wear and breakage caused by exposure, while maintaining a clean appearance.

[0030] Furthermore, the shoulder straps 42 are 5cm wide, curved bands with breathable mesh on the inside and a high-elasticity woven layer on the outside, featuring high tensile strength and good elastic recovery. The distance between the two shoulder straps 42 is 20cm, fitting the width of an adult's head, ensuring that the head can easily pass through without pressure when wearing the helmet. The chest strap 43 is a 3cm wide elastic band that connects to both sides of the chest plate 44. The weight of the power box 41 (approximately 300g) is distributed to the shoulders and chest through the shoulder straps 42 and chest strap 43, significantly improving wearing comfort and stability, and avoiding the problem of the helmet tipping forward and slipping off due to the traditional method of concentrating weight on the front.

[0031] The working principle is as follows: First, the construction personnel wear it from top to bottom, with the head passing through the shoulder strap 42 and chest strap 43 in sequence, so that the power box 41 fits stably against the torso, and the power supply 4 is worn. Its weight is evenly distributed on the shoulders and chest through the shoulder strap 42 and chest strap 43, avoiding the head from bearing weight.

[0032] Next, put the helmet body 1 on your head and adjust it to a comfortable position using the straps 9 on the inner helmet support 8. The buckle structure ensures a secure connection between the inner helmet support 8 and the helmet body 1. Then, align the connector 45 of the power supply cable 4 with the socket 3 on the monitoring base 2 at the back of the helmet body 1 and insert it to establish a circuit connection between the power box 41 and the monitoring cameras 5. The rechargeable lithium battery inside the power box 41 will then power the four monitoring cameras 5.

[0033] During operation, monitoring cameras 5, located on the four monitoring seats 2 in the front, back, left, and right directions of the safety helmet body 1, simultaneously capture construction footage. The lenses are designed to be tilted slightly downwards at 10° to effectively capture details of the ground work and the surrounding environment. The collected video data enters the through-channel of the cable routing arc protrusion 6 through the internal cavity of the monitoring seat 2, and after being connected in parallel with the main cable via flexible cabling, it is transmitted through the socket 3 to the power supply 4 (or an external data storage device), realizing real-time recording or remote transmission of multi-directional construction footage.

[0034] During this process, the integrated molding structure of the safety helmet body 1, monitoring base 2, wiring arc protrusion 6 and brim 7 provides stable support. The inverted "L"-shaped monitoring base 2 protects the camera 5 from direct impact from falling objects. The concealed wiring design avoids damage to exposed wiring. The shoulder strap power supply layout and the symmetrical distribution of four cameras together ensure wearing balance. 360° monitoring of the construction scene can be achieved without frequently turning the head.

[0035] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
