Description

Technical Field

[0001] The present application relates to the field of power engineering, and in particular to fireproofing material construction equipment. Background Art

[0002] Rapid cable foam fireproof sealant is a material used to fill and seal holes where cables pass through walls or floors. It expands in the event of a fire, forming a fire barrier that prevents the spread of fire and smoke penetration. This technology plays an important role in construction and electrical engineering, particularly in improving the fire safety of buildings.

[0003] However, some walls or floors have complex cable hole structures, or the cable holes are long and deep, or the cable holes are curved, which makes the construction of fast cable foaming fireproof sealant difficult.

[0004] Or due to climatic reasons, the temperature at the construction site is low, which may also lead to unsatisfactory expansion performance and sealing effect of the fast cable foaming fireproof sealant.

[0005] To improve the construction of complex cable holes and overcome technical challenges such as slow foaming in low-temperature environments, a fireproof and waterproof sealant for power cables is developed. The filler is doped with a fragmented resin fiber mesh, woven using warp and weft threads, both of which are made of resin fibers. During drawing, the resin fibers in one of the warp and weft threads are bonded with a soft magnetic material while molten, allowing them to be attracted by the magnetic field and evenly channeling the magnetic field deep into the fluid sealant. The other resin fibers in the other warp and weft threads are bonded with a conductive material while molten, making the fluid sealant conductive and capable of generating heat in high-frequency magnetic fields. Utility Model Content

[0006] The purpose of the present utility model is to provide a controllable curing device for electric sealant to solve at least one of the above technical problems.

[0007] The technical problem solved by the present invention can be achieved by adopting the following technical solutions:

[0008] The controllable curing device of electric sealant comprises a device housing provided with a hand-held handle;

[0009] A telescopic mechanism is also assembled in the device housing;

[0010] It also includes a sealant electromagnetic induction heating plate, which has an electromagnetic heating system;

[0011] It also includes an electromagnet having a magnetic core with a coil wound around the magnetic core;

[0012] The coil is connected to a power supply device that outputs alternating current as a magnetic field controller;

[0013] A sealant electromagnetic induction heating plate is fixed on the equipment housing;

[0014] An electromagnet is fixed to the telescopic end of the telescopic mechanism.

[0015] In the above design, an electromagnetic heating system is provided in the controllable curing device of the electric sealant. The electromagnetic heating system can generate a high-frequency alternating magnetic field. The colloid of the electric sealant in the magnetic field is doped with a conductive substance, so the substance will generate eddy current, thereby causing the colloid to heat up. The curing speed of the electric sealant under the heated condition is significantly improved, thereby realizing the controllable curing of the electric sealant.

[0016] In the above design, the controllable curing device for the electric sealant further includes an electromagnet connected to a magnetic field controller capable of providing an alternating current. The magnetic field controller includes a corresponding alternating current circuit. Under the influence of the alternating current output by the magnetic field controller, the electromagnet generates a magnetic force with cyclically reversed polarity. The magnetic lines of force act on the magnetic material within the electric sealant, thereby causing the magnetic material to vibrate. This has the following beneficial effects: first, the vibration of the magnetic material stirs the sealant, improving the mixing of the components; second, the vibration of the magnetic material removes bubbles from the sealant, improving the sealing effect of the sealant; and finally, the vibration of the magnetic material strengthens the contact between the magnetic material and the electric sealant, eliminating surface tension.

[0017] In the above design, a telescopic mechanism is installed in the device casing. The beneficial effect of setting up the telescopic mechanism is that when the telescopic mechanism is in the extended state, the electromagnetic heating system and the electromagnet system can be separated to prevent the electromagnet device from being affected by the high-frequency magnetic field and causing heat.

[0018] Furthermore, a copper mesh with a silver coating is provided around the electromagnetic heating system as a side shielding mesh;

[0019] A copper mesh with a silver-plated layer is also provided at the bottom of the electromagnetic heating system as a bottom shielding mesh, and the bottom shielding mesh is electrically isolated from the electromagnetic heating system.

[0020] In the above design, a side shielding net is provided on the outer side of the electromagnetic heating system, and a bottom shielding net is provided at the bottom of the electromagnetic heating system. The beneficial effect of providing the shielding net is to prevent the leaked high-frequency magnetic field from affecting the health of users on the sides and rear.

[0021] The shielding net uses a silver-plated shielding net. The beneficial effect is that the internal resistance of silver is extremely low, and the induced current generated by the high-frequency magnetic field is difficult to cause the silver-plated shielding net to generate heat, so it can be used to shield and isolate the high-frequency magnetic field.

[0022] Furthermore, the telescopic end adopts a mounting bracket, and the mounting bracket is equipped with the electromagnet;

[0023] The device housing includes an inner cavity provided on the back of the sealant electromagnetic induction heating plate;

[0024] The inner cavity has a placement space for accommodating the mounting bracket;

[0025] The electromagnet has a state of extending out of the inner cavity and a state of being retracted into the inner cavity through the telescopic mechanism;

[0026] When the mounting bracket is located in the placement space state, a handle for pulling is provided on the side of the mounting bracket facing outside the shell.

[0027] In the above design, the equipment casing includes the back of the sealant electromagnetic induction heating plate, and is provided with an inner cavity. When the telescopic mechanism is retracted, the mounting bracket and the electromagnet mounted thereon are stored in the inner cavity. The beneficial effect is that the volume of the electric sealant controllable curing device is reduced, making it easy to carry.

[0028] Furthermore, two hand-held handles are symmetrically arranged on the outside of the shell; the hand-held handles are made of non-conductive material.

[0029] The above design has the beneficial effect that the handles are symmetrically arranged on the outside of the device housing, making it easier for the user to hold the device. The handles are made of non-conductive material to prevent the conductive material handle from being heated by the electromagnetic heating system and becoming difficult to hold.

[0030] Furthermore, a protective cover is provided outside the electromagnet; the protective cover is made of one of polybenzimidazole and polyetheretherketone.

[0031] In the above design, the protective cover provided outside the electromagnet is used to protect the magnetic core material and the coil provided thereon from physical damage, and can also prevent damage to the electrical equipment caused by short circuit or open circuit due to water and fire.

[0032] The beneficial effect of using polybenzimidazole and polyetheretherketone as protective covers is that they have better mechanical protection strength and beneficial properties of high temperature resistance, thereby enhancing the protection capabilities of fire and water release.

[0033] Furthermore, the magnetic core is made of manganese-zinc ferrite.

[0034] In the above design, the beneficial effect of using manganese-zinc ferrite material for the magnetic core is that it can improve the magnetic permeability and magnetic flux density and enhance the magnetic coupling force of the electromagnet.

[0035] Furthermore, the magnetic core includes a chassis, and a cylindrical protrusion is provided in the middle of the chassis;

[0036] The bottom plate is provided with an annular protrusion extending upward along the periphery, which is called the first cylinder;

[0037] A circular protrusion is provided between the first cylinder and the cylindrical protrusion, which is called the second cylinder;

[0038] The chassis, the cylindrical protrusion, the first cylinder and the second cylinder form an integrated magnetic core;

[0039] A coil is provided between the first cylinder and the second cylinder as a first coil;

[0040] A coil is provided between the second cylinder and the cylindrical protrusion as a second coil;

[0041] The first coil and the second coil are connected in parallel to form a coil of an electromagnet.

[0042] In the above design, by arranging the first cylinder and the second cylinder on the chassis of the magnetic core, two coil windings can be arranged in one magnetic core. The beneficial effect is that it provides a more uniform magnetic field and enhances the magnetic flux, which allows the magnetic force of the electromagnet to act at a longer distance, thereby achieving the effect of vibration stirring of the magnetic material in the power sealant.

[0043] The utility model integrates an electromagnetic heating system and an electromagnet, and realizes the control of the curing of the electric sealant by heating and vibrating the electric sealant colloid. The technical scheme of designing a telescopic structure and installing a shielding net solves the problem of the high-frequency magnetic field of the electromagnetic heating system interfering with the electromagnet and the problem of protecting the personal safety of the user.

[0059] A sealant electromagnetic induction heating plate is fixed on the equipment housing;

[0060] An electromagnet is fixed to the telescopic end of the telescopic mechanism.

[0061] In this embodiment, an electromagnetic heating system is provided in the controllable curing device of the electric sealant. The electromagnetic heating system can generate a high-frequency alternating magnetic field. The colloid of the electric sealant located in the magnetic field is doped with a conductive substance, so the substance will generate eddy current, thereby causing the colloid to heat up. The curing speed of the electric sealant under the heated condition is significantly improved, thereby realizing the controllable curing of the electric sealant.

[0062] In this embodiment, the controllable curing device for the electric sealant further includes an electromagnet connected to a magnetic field controller capable of providing an alternating current. The magnetic field controller includes a corresponding alternating current circuit. Under the influence of the alternating current output by the magnetic field controller, the electromagnet generates a magnetic force with cyclically reversed polarity. The magnetic lines of force act on the magnetic material within the electric sealant colloid, thereby causing the magnetic material to vibrate. This has the following beneficial effects: first, the vibration of the magnetic material stirs the colloid, thereby improving the mixing of the components of the electric sealant; second, the vibration of the magnetic material removes bubbles from the sealant colloid, thereby improving the sealing effect of the sealant; and finally, the vibration of the magnetic material strengthens the contact between the magnetic material and the electric sealant, eliminating surface tension.

[0063] In this embodiment, a telescopic mechanism is installed in the device casing. The beneficial effect of setting up the telescopic mechanism is that when the telescopic mechanism is in the extended state, the electromagnetic heating system and the electromagnet system can be separated to prevent the electromagnet device from being affected by the high-frequency magnetic field and causing heat.

[0064] Furthermore, a copper mesh with a silver coating is provided around the electromagnetic heating system as a side shielding mesh;

[0065] A copper mesh with a silver-plated layer is also provided at the bottom of the electromagnetic heating system as a bottom shielding mesh, and the bottom shielding mesh is electrically isolated from the electromagnetic heating system.

[0066] In this embodiment, a side shielding net is provided on the outer side of the electromagnetic heating system, and a bottom shielding net is provided at the bottom of the electromagnetic heating system. The beneficial effect of providing the shielding net is to prevent the leaked high-frequency magnetic field from affecting the health of users on the sides and rear.

[0067] The shielding net uses a silver-plated shielding net. The beneficial effect is that the internal resistance of silver is extremely low, and the induced current generated by the high-frequency magnetic field is difficult to cause the silver-plated shielding net to generate heat, so it can be used to shield and isolate the high-frequency magnetic field.

[0068] Furthermore, the telescopic end adopts a mounting bracket, and the mounting bracket is equipped with the electromagnet;

[0069] The device housing includes an inner cavity provided on the back of the sealant electromagnetic induction heating plate;

[0070] The inner cavity has a placement space for accommodating the mounting bracket;

[0071] The electromagnet has a state of extending out of the inner cavity and a state of being retracted into the inner cavity through the telescopic mechanism;

[0072] When the mounting bracket is located in the placement space state, a handle for pulling is provided on the side of the mounting bracket facing outside the shell.

[0073] In this embodiment, the device housing includes the back of the sealant electromagnetic induction heating plate, and is provided with an inner cavity. When the telescopic mechanism is retracted, the mounting bracket and the electromagnet mounted thereon are stored in the inner cavity. The beneficial effect is that the volume of the electric sealant controllable curing device is reduced, making it easier to carry.

[0074] Optimization, the electromagnetic heating system adopts an electromagnetic heating system with an operating frequency of 20-30kHz and an output power of 200-500w.

[0075] In this embodiment, the optimal curing temperature of the sealant is between 50 and 80 degrees Celsius, so the output power of the electromagnetic heating system is controlled between 200 watts and 500 watts, which can meet the needs of the electric sealant curing process.

[0076] Furthermore, two hand-held handles are symmetrically arranged on the outside of the shell; the hand-held handles are made of non-conductive material.

[0077] In this embodiment, the beneficial effect is that the handles are symmetrically arranged on the outside of the device housing, which can be convenient for the user to hold and use. The handles are made of non-conductive material to prevent the conductive material handle from being heated by the electromagnetic heating system and making it difficult to hold.

[0078] Furthermore, a protective cover is provided outside the electromagnet; the protective cover is made of one of polybenzimidazole and polyetheretherketone.

[0079] In this embodiment, the protective cover provided outside the electromagnet is used to protect the magnetic core material and the coil provided thereon from physical damage, and can also prevent damage to the electrical equipment caused by short circuit or open circuit due to water and fire.

[0080] The beneficial effect of using polybenzimidazole and polyetheretherketone as protective covers is that they have better mechanical protection strength and beneficial properties of high temperature resistance, thereby enhancing the protection capabilities of fire and water release.

[0081] Furthermore, the magnetic core is made of manganese-zinc ferrite.

[0082] In this embodiment, the beneficial effect of using manganese-zinc ferrite material for the magnetic core is that it can improve the magnetic permeability and magnetic flux density, and enhance the magnetic coupling force of the electromagnet.

[0083] Reference Figure 3 As shown, the magnetic core includes a chassis, and a cylindrical protrusion is provided in the middle of the chassis;

[0084] The bottom plate is provided with an annular protrusion extending upward along the periphery, which is called the first cylinder;

[0085] A circular protrusion is provided between the first cylinder and the cylindrical protrusion, which is called the second cylinder;

[0086] The chassis, the cylindrical protrusion, the first cylinder and the second cylinder form an integrated magnetic core;

[0087] A coil is provided between the first cylinder and the second cylinder as a first coil;

[0088] A coil is provided between the second cylinder and the cylindrical protrusion as a second coil;

[0089] The first coil and the second coil are connected in parallel to form a coil of an electromagnet.

[0090] In this embodiment, by arranging the first cylinder and the second cylinder on the chassis of the magnetic core, two coil windings can be arranged in one magnetic core. The beneficial effect is that a more uniform magnetic field is provided and the magnetic flux is enhanced, so that the magnetic force of the electromagnet can act at a greater distance, thereby achieving the effect of vibration stirring of the magnetic material in the power sealant.

[0091] Preferably, the electric sealant cured by the controllable curing device is an electric sealant using a fragmented resin fiber web as a filler;

[0092] The resin fiber mesh is woven by alternating warp and weft resin fiber threads;

[0093] One of the resin fiber lines constituting the warp and weft is provided with a composite layer of soft magnetic material;

[0094] Another resin fiber line constituting the warp and weft is provided with a composite layer of conductive material.

[0095] In this embodiment, when the resin fiber filaments are drawn, they are bonded to the soft magnetic material in a molten state to form a composite layer. The soft magnetic material has high magnetic permeability and weak remanence, and will be in a vibrating state in the alternating magnetic field of the electromagnet system. In addition, the magnetically conductive soft magnetic material is in the fluid glue, and the high-frequency magnetic field can be uniformly introduced into the deep of the fluid glue, thereby driving the overall uniform temperature rise of the fluid glue. The beneficial effect is that it keeps the power sealant uniformly cured, thereby improving the curing efficiency and curing quality of the power sealant.

[0096] In this embodiment, when the resin fiber filaments are drawn, they are bonded to the conductive material in a molten state to form a composite layer. The conductive material in the fluid glue causes the fluid glue to have a certain conductivity. In the high-frequency magnetic field formed by the electromagnetic heating system, the fluid glue will induce eddy currents due to its conductivity, and generate heat due to the internal resistance of the fluid glue, causing the glue to heat up. The beneficial effect is that the increase in temperature can increase the curing speed of the electrical sealant.

[0097] Furthermore, in order to provide a concise description of the exemplary embodiments, all features of the actual embodiment may not be described, i.e., those features that are not relevant to the best mode presently contemplated for carrying out the invention or those that are not relevant to implementing the invention.
