Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.
The first embodiment is as follows:
referring to fig. 1-2, a can adjust safety protection system of temperature in building, including upper plate 1 and hypoplastron 2, and through bracing piece 3 fixed connection between upper plate 1 and the hypoplastron 2, be equipped with two safety nets 4 between upper plate 1 and the hypoplastron 2, bar groove 6 has been seted up to the lateral wall of bracing piece 3, sealed sliding connection has magnetic slider 8 in bar groove 6, and magnetic slider 8's lower extreme passes through vibrating spring 9 elastic connection at the interior bottom in bar groove 6, and vibrating spring 9 is made by memory alloy material, and the interior top in bar groove 6 has seted up exhaust hole 61, guarantee through setting up exhaust hole 61 that magnetic slider 8 up-and-down motion is unimpeded.
Specifically, the vibration spring 9 made of the memory alloy material is in an extension state when the temperature is high in summer, and can ensure that the lowest motion point of the magnetic slider 8 is always higher than the spiral coil 7 in the vertical vibration process, while the vibration spring 9 is in a contraction state when the temperature is low in winter, and can ensure that the magnetic slider 8 can enter and exit the spiral coil 7 in the vertical vibration process.
Meanwhile, during specific installation, a plurality of vibrating springs 9 with different natural frequencies can be arranged in the strip-shaped groove 6 to receive noise generated by construction equipment with different frequency bands, so that the system can be ensured to operate smoothly.
Further, a power amplifier 81 fixedly connected with the vibration spring 9 is embedded at the lower end of the magnetic sliding block 8, so that noise waves generated by construction equipment can be amplified, and sufficient kinetic energy can be generated to vibrate the vibration spring 6 and drive the magnetic sliding block 8 to move up and down; meanwhile, the power amplifier 81 and the vibration spring 9 are directly and fixedly connected, and the solid body conducts the vibration of sound at the fastest speed and has the smallest energy loss, so that the transmission rate of sound wave energy can be improved.
The embedded spiral coil 7 that is equipped with in bar groove 6, the lateral wall of bracing piece 3 are equipped with a plurality of heating wires 5 with the coupling of spiral coil 7, and heating wire 5 extends to the mesh of safety net 4 in, and heating wire 5 does not contact with safety net 4.
The water storage cavity 21 has been seted up to the lateral wall of hypoplastron 2, and water storage cavity 21 communicates through one-way inlet tube 13 with bar groove 6, and the one-way outlet pipe 14 rather than inside intercommunication is installed to the interior bottom in bar groove 6, and the delivery end of one-way outlet pipe 14 installs atomizer 141. In particular, during the manufacturing process, a one-way valve can be arranged in the water inlet pipe or the water outlet pipe, so that the water inlet pipe or the water outlet pipe has the function of one-way water inlet or outlet.
In the embodiment, in winter with cold weather, the vibration spring 9 made of memory alloy is in a contraction state, at the moment, the vibration spring 9 and the magnetic slider 8 at the upper end thereof are at a lower position, when the construction operation is carried out in the building, because the natural frequency of the vibration spring 9 is the same as the natural frequency of construction equipment, the vibration spring 9 resonates and pushes the magnetic slider 8 to reciprocate up and down in the construction process, the magnetic slider 8 continuously enters and exits the spiral coil 7, the magnetic flux in the spiral coil 7 is continuously changed to generate induction current, so that the electric heating wire 5 coupled with the spiral coil 7 is electrified to generate heat, when cold air is blown into the building through the safety net 4, the electric heating wire 5 in the meshes of the safety net 4 is heated and then enters the room, so that the cold air entering the building can be changed into warm air, the working environment temperature in the building is always in a high state, the system does not consume electric energy, the sound wave kinetic energy of noise generated by construction operation equipment is converted into heat energy to be heated, and the system is energy-saving and environment-friendly.
In hot summer, the vibration spring 9 made of memory alloy is in an extension state, the vibration spring 9 and the magnetic slider 8 at the upper end of the vibration spring are at a higher position, when the magnetic slider 8 moves up and down in the construction operation in a building, the magnetic slider 8 cannot enter and exit the spiral coil 7 any more, the magnetic flux in the spiral coil 7 is not changed all the time, and no current is generated any more, so the electric heating wire 5 cannot generate heat any more.
Simultaneously in the hot summer of weather, can add water in to water storage chamber 21, when magnetic slider 8 moves up, can be with the water in the water storage chamber 21 by one-way inlet tube 13 suction strip groove 6, when magnetic slider 8 moves down, because the noise frequency is higher, therefore vibrating spring 9 and the frequency that magnetic slider 8 reciprocated are also very high, so can be with the water in strip groove 6 by one-way outlet pipe 14 and atomizer 141 blowout, and form the water smoke, the heat in the building can be evaporated fast and absorbed to the water smoke, thereby cool down the processing in the building, simultaneously still can promote the humidity in the building, the dust that spun water smoke still produced in to the work progress is handled, further optimize the construction environment in the building.
Example two:
referring to fig. 3, unlike the first embodiment, a threaded sleeve 12 is rotatably connected to the lower end of the upper plate 1, a screw 10 is screwed into the threaded sleeve 12, the lower end of the screw 10 penetrates through the side wall of the support rod 3 and is fixedly connected to the magnetic slider 8, and a plurality of axial fans 11 are coaxially and fixedly connected to the threaded sleeve 12.
In this embodiment, in hot summer of weather, magnetism slider 8 reciprocates the in-process and will constantly promote screw rod 10 and reciprocate to make and make a round trip to rotate with screw rod 10 complex threaded sleeve 12, and make axial fan 11 make a round trip to rotate, can accelerate the air near safety net 4 and flow, thereby promote the inside and outside air of building and take place the exchange, make the heat in the building can distribute away fast, play the promotion effect to the cooling.
And under the condition of no wind in winter, cold wind can be generated, and then is heated by the heating wire 5 into warm wind and then is blown into the building, so that the interior of the building can be kept in a high-temperature state.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
