Utility Model Content

[0004] The purpose of this utility model is to provide a multifunctional building construction safety monitoring and early warning device to solve the problems mentioned in the background art.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] A multifunctional building construction safety monitoring and early warning device includes a support mechanism, a monitoring mechanism, and an angle adjustment mechanism. The monitoring mechanism includes a fixed column, a battery box installed at the upper end of the fixed column, an alarm installed at the center of the upper end of the battery box, and support rods connected to the four corners of the upper end of the battery box. The upper ends of the four support rods are connected to square plates. The upper end of the alarm penetrates the square plate and is equipped with a gas sensor. The angle adjustment mechanism includes a pair of first connecting boxes and a pair of second connecting boxes. The opposite sides of the pair of first connecting boxes are connected to one side of the front and back of the battery box, respectively, and the opposite sides of the pair of second connecting boxes are connected to the other side of the front and back of the battery box, respectively. A rotating rod is rotatably connected between the pair of first connecting boxes and the pair of second connecting boxes. The opposite sides of the two rotating rods are connected to mounting plates, and solar panels are embedded in the upper ends of the two mounting plates. Furthermore, one end of each of the two rotating rods extends through one of the first connecting boxes and one of the second connecting boxes into their respective interiors. A second micro motor is connected to the front of each of the first and second connecting boxes. The output ends of the two second micro motors extend into the interior of each of the first and second connecting boxes. Synchronous pulleys are fitted onto the exterior of the output ends of adjacent second micro motors and one end of each rotating rod. A synchronous belt is wound between a pair of synchronous pulleys. The advantage of this further solution is that by setting two second micro motors with opposite rotation of their output ends, when the two second micro motors are working, they can easily drive the two rotating rods to rotate under the action of the synchronous pulleys and the synchronous belt.

[0007] Furthermore, an inverter is connected to the bottom of the battery box, a photovoltaic charging controller is installed on the top of the inverter, and a storage battery is installed on the top of the photovoltaic charging controller. The solar panel, inverter, photovoltaic charging controller and storage battery are electrically connected by wires.

[0008] The beneficial effect of adopting the above-mentioned further scheme is that, through the coordinated use of solar panels, inverters, photovoltaic charge controllers and batteries, the solar panels are responsible for collecting solar energy and converting it into electrical energy, the inverters convert DC power into AC power, the photovoltaic charge controllers protect the batteries from overcharging or over-discharging, and the batteries store electrical energy.

[0009] Furthermore, the battery is electrically connected to the alarm, gas sensor, and two second micro motors via wires.

[0010] The advantage of adopting the above-mentioned further solution is that by electrically connecting the battery to the alarm, the gas sensor and the two second micro motors, the battery can supply power to the alarm, the gas sensor and the two second micro motors.

[0011] Furthermore, a control panel is installed on the back of the battery box, and the control panel is electrically connected to the gas sensor and the alarm via wires.

[0012] The beneficial effect of adopting the above-mentioned further solution is that, through the combined use of gas sensors, control panels, and alarms, various harmful gases may be released at the construction site during building construction projects. Volatile organic compounds in building materials may release harmful gases such as benzene and formaldehyde, and the exhaust gas generated during welding operations contains harmful substances such as carbon monoxide. By monitoring air quality through gas sensors and transmitting the monitoring data to the control panel, the control panel can control the alarm to work, thereby alerting staff to changes in the environment.

[0013] Furthermore, the support mechanism includes a support cylinder, the upper end of which is fitted with the bottom end of the fixed column, and the support cylinder and the fixed column are connected by several bolts. The bottom end of the support cylinder is connected to a mounting base, and three first hinge seats are mounted on the outside of the mounting base. Each of the three first hinge seats has a support plate hinged inside. One end of the support plate has a mounting hole on its top surface, and the bottom end of the support plate is flush with the bottom end of the mounting base.

[0014] The beneficial effect of adopting the above-mentioned further solution is that by setting a support cylinder and connecting the support cylinder and the fixed column with several bolts, the fixed column and the support cylinder form an integral whole. By opening mounting holes on the support plate, when all three support plates are in an unfolded horizontal state, it is easy to fix the device in a designated position through the mounting holes and fastening bolts.

[0015] Furthermore, the upper end of the support plate is connected to a second hinge seat, the outer wall of the support cylinder is slidably connected to a hollow ring, the outside of the hollow ring is connected to three third hinge seats, and a connecting rod is hinged between the opposing second hinge seats and the second hinge seats.

[0016] The beneficial effect of adopting the above-mentioned further solution is that when the hollow ring slides from the upper part to the lower part of the support cylinder, the support plate, which was originally in a retracted vertical state, will be transformed into an unfolded horizontal state under the action of the second hinge seat, connecting rod and third hinge seat, so that the bottom end of the support plate is flush with the bottom end of the mounting seat, thus making it easier to place the device in the designated position.

[0017] Furthermore, the outer wall of the support cylinder is provided with three sliding grooves, and a lead screw is rotatably connected inside the support cylinder. A circular plate is threadedly connected to the outside of the lead screw, and three sliding strips are connected to the outside of the circular plate. One end of each of the three sliding strips extends to the outside of the support cylinder through the three sliding grooves and is connected to the inner wall of the hollow ring.

[0018] The beneficial effect of adopting the above-mentioned further solution is that, by setting a lead screw, when the lead screw rotates, the circular plate connected to its external thread can move linearly under the sliding limit action of the slide bar and slide groove. Since the end of the three slide bars away from the circular plate is connected to the inner wall of the hollow ring, when the circular plate and slide bars move linearly, the hollow ring can move linearly outside the support cylinder.

[0019] Furthermore, a first micro motor is installed at the bottom of the mounting base, and the output end of the first micro motor is connected to the lead screw for transmission.

[0020] The beneficial effect of adopting the above-mentioned further solution is that by installing the first micro motor, it is convenient to drive the lead screw to rotate when the first micro motor is working.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: This multifunctional building construction safety monitoring and early warning device, by setting up a battery box, facilitates the installation of the inverter, photovoltaic charging controller, and storage battery. By setting up a gas sensor and an alarm, the gas sensor monitors air quality and transmits the monitoring data to the control panel, which then controls the alarm to work, thereby alerting staff to changes in the environment. By setting up two second micro motors with opposite output directions, when the two second micro motors are working, they facilitate the rotation of two rotating rods under the action of a synchronous pulley and a synchronous belt, causing the two mounting plates to rotate the solar panels embedded inside them, thereby adjusting the angle of the solar panels and enabling the solar panels to absorb solar energy to the maximum extent, thus improving the conversion efficiency. The solar panels are responsible for collecting solar energy and converting it into electrical energy. The inverter converts DC power into AC power. The photovoltaic charging controller protects the storage battery from overcharging or over-discharging. The storage battery stores electrical energy. By electrically connecting the storage battery to the alarm, gas sensor, and two second micro motors, the storage battery can supply power to the alarm, gas sensor, and two second micro motors.

The solar panels 3005 are responsible for collecting solar energy and converting it into electrical energy. The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-5This utility model provides a technical solution: one end of each of the two rotating rods 3003 extends through one of the first connecting boxes 3001 and one of the second connecting boxes 3002 into the interior. A second micro motor 3007 is connected to the front of each of the first connecting boxes 3001 and the second connecting box 3002. The output ends of the two second micro motors 3007 extend into the interior of each of the first connecting boxes 3001 and the second connecting box 3002. Synchronous pulleys 3006 are fitted onto the outer sides of the output ends of adjacent second micro motors 3007 and the outer sides of one end of each rotating rod 3003. A synchronous belt is wound between a pair of synchronous pulleys 3006. A battery box 2002 is also included. An inverter 2007 is connected to the bottom of the internal structure. A photovoltaic charging controller 2008 is installed on the top of the inverter 2007, and a battery 2009 is installed on the top of the photovoltaic charging controller 2008.

The outputs of the two second micro motors 3007 rotate in opposite directions. When the two second micro motors 3007 are working, they drive the two rotating rods 3003 to rotate under the action of the synchronous pulley 3006 and the synchronous belt. This causes the two mounting plates 3004 to rotate the solar panels 3005 embedded inside them. The solar panels 3005 are responsible for collecting solar energy and converting it into electrical energy. The inverter 2007 converts DC power into AC power. The photovoltaic charging controller 2008 protects the battery 2009 from overcharging or over-discharging. The battery 2009 stores electrical energy. By connecting the battery 2009 with the alarm 2003, the gas sensor 2006, and the two second micro motors... The motor 3007 is electrically connected, allowing the battery 2009 to power the alarm 2003, the gas sensor 2006, and the two second micro motors 3007. Through the combined use of the gas sensor 2006, the control panel, and the alarm 2003, various harmful gases may be released at the construction site during building construction. Volatile organic compounds in building materials may release harmful gases such as benzene and formaldehyde, and the exhaust gas generated during welding operations contains harmful substances such as carbon monoxide.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-5This utility model provides a technical solution: the support mechanism 100 includes a support cylinder 1001, the upper end of the support cylinder 1001 is fitted with the bottom end of the fixed column 2001, and the support cylinder 1001 and the fixed column 2001 are connected by several bolts. A mounting base 1002 is connected to the bottom end of the support cylinder 1001. Three first hinge seats 1003 are mounted on the outside of the mounting base 1002. A support plate 1004 is hinged inside each of the three first hinge seats 1003. A mounting hole is opened on the top surface of one end of the support plate 1004, and the bottom end of the support plate 1004 is flush with the bottom end of the mounting base 1002. A second hinge seat 1005 is connected to the upper end of the support plate 1004. The outer wall of the support cylinder 1001 slides... A hollow ring 1010 is dynamically connected, and three third hinge seats 1011 are externally connected to the hollow ring 1010. A connecting rod 1012 is hinged between the opposing second hinge seats 1005 and the second hinge seat 1005. Three sliding grooves 1006 are opened on the outer wall of the support cylinder 1001, and a lead screw 1007 is rotatably connected inside the support cylinder 1001. A circular plate 1008 is threadedly connected to the outside of the lead screw 1007, and three sliding strips 1009 are externally connected to the circular plate 1008. One end of each of the three sliding strips 1009 extends to the outside of the support cylinder 1001 through the three sliding grooves 1006 and is connected to the inner wall of the hollow ring 1010. A first miniature is installed at the bottom of the inner part of the mounting base 1002. The output end of the first micro motor 1013 is connected to the lead screw 1007. A support cylinder 1001 is provided, and the support cylinder 1001 is connected to the fixed column 2001 by several bolts, thus forming a whole with the fixed column 2001. By installing the first micro motor 1013, when the first micro motor 1013 is working, it facilitates the rotation of the lead screw 1007. When the lead screw 1007 rotates, the circular plate 1008, which is externally threaded, moves linearly under the sliding limit action of the slide bars 1009 and the slide groove 1006. Since the ends of the three slide bars 1009 away from the circular plate 1008 are connected to the inner wall of the hollow ring 1010, When the circular plate 1008 and the slide bar 1009 move linearly, the hollow ring 1010 moves linearly outside the support cylinder 1001. When the hollow ring 1010 slides from the upper part to the lower part of the support cylinder 1001, the support plate 1004, which was originally in a retracted vertical state, is transformed into an unfolded horizontal state under the action of the second hinge seat 1005, the connecting rod 1012 and the third hinge seat 1011. This makes the bottom end of the support plate 1004 flush with the bottom end of the mounting seat 1002, which makes it easy to place the device in a designated position. By opening mounting holes on the support plate 1004, when all three support plates 1004 are in an unfolded horizontal state, it is easy to fix the device in a designated position through the mounting holes and fastening bolts.

[0033] Specifically, the working principle of this multifunctional building construction safety monitoring and early warning device is as follows: During use, two second micro motors 3007 are installed, with their outputs rotating in opposite directions. When the two micro motors 3007 are working, they drive two rotating rods 3003 to rotate under the action of a synchronous pulley 3006 and a synchronous belt. This causes the two mounting plates 3004 to rotate the solar panels 3005 embedded within them. When the two rotating rods 3003 rotate in both directions, the two mounting plates 3004 drive the solar panels 3005 to rotate, thereby adjusting the angle of the solar panels 3005. This allows the solar panels 3005 to absorb solar energy to the maximum extent, thus improving conversion efficiency. The solar panels 3005 are responsible for collecting solar energy and converting it into electrical energy. The inverter 2007 converts the direct current (DC) to alternating current (AC). The photovoltaic charging controller 2008 protects the battery 2009 from overcharging or over-discharging. The battery 2009 stores electrical energy and is electrically connected to the alarm 2003, gas sensor 2006, and two second micro motors 3007. This allows the battery 2009 to power the alarm 2003, gas sensor 2006, and two second micro motors 3007. Through the coordinated use of the gas sensor 2006, control panel, and alarm 2003, various harmful gases may be released at the construction site during building construction. Volatile organic compounds in building materials may release harmful gases such as benzene and formaldehyde, and waste gas generated during welding operations may contain harmful substances such as carbon monoxide. The gas sensor 2006 monitors the air quality and transmits the monitoring data to the control panel, which then controls the alarm 2003 to alert workers to changes in the environment.
