Description

Technical Field

[0001] The utility model relates to the technical field of passive opening and closing devices for nuclear power plants, in particular to a passive anti-seismic, fire-proof, heat-insulating and water-draining window. Background Art

[0002] The passive anti-seismic, fire-proof, heat-insulating and water-draining window is a key device for controlling fire accidents and flooding accidents in the nuclear island of a nuclear power plant. The passive anti-seismic, fire-proof, heat-insulating and water-draining window is normally in a normally closed state. When a fire occurs, the window sash and the window frame form a heat-insulating whole to block the spread of fire and toxic high-temperature smoke; when a flooding accident occurs, the floating ball opening device unlocks the window sash to quickly drain the flood water in the room.

[0003] However, in the process of implementing the technical solution of the utility model in the embodiments of the present application, the applicant found that the above technology has at least the following technical problems:

[0004] 1. It is impossible to meet the requirements of fire prevention and water drainage simultaneously.

[0005] 2. The traditional water-draining window uses a tension spring to cooperate with the water pressure after immersion to open the louvers. The tension spring is in a stretched state for a long time, which is prone to metal fatigue and performance degradation. Affected by the friction coefficient of multi-louver transmission, the tension of the tension spring becomes uncontrollable, and the water drainage level control is fuzzy. The accuracy of the immersion level control is poor. Summary of the Utility Model

[0006] By providing a passive anti-seismic, fire-proof, heat-insulating and water-draining window, the embodiment of the present application adopts a classified sealing control method, which can effectively meet the sealing requirements during fire prevention and water drainage. The floating ball opening device is adopted to ensure that the floating ball opening device can have a rapid response, the water drainage level is accurately controlled, and the structure is simple.

[0007] The embodiment of the present application provides a passive anti-seismic, fire-proof, heat-insulating and water-draining window, including an outer fixed frame. A window frame is arranged inside the outer fixed frame. A window sash is arranged inside the window frame. The window sash is fixed to the window frame through a rotating shaft to form a rotating pair. A floating ball opening device is fixed to the bottom inside the window frame through bolts. The floating ball opening device includes: a floating ball, a connecting rod, a support and a deep groove ball bearing. The floating ball is fixedly connected to the connecting rod through a fastener. The connecting rod is movably connected to the support through a deep groove ball bearing and a shaft. The support is fixedly connected to the window frame through bolts.

[0008] Furthermore, the window frame includes a frame body, an outer strip, an inner strip, a sponge rubber seal and a calcium silicate fire-proof board. The frame body, the outer strip and the inner strip are formed by bending thin plates and then welded together. The welding gaps are fixed by intermittent welding, and fire-proof sealant is applied to the gaps. The frame body is filled with calcium silicate fire-proof board. Sponge rubber seals are pasted on the contact surfaces of the outer strip and the inner strip with the window sash.

[0009] Further, the sash is limited by an inner stop strip and an outer stop strip.

[0010] Further, the sash includes: an intermediate plate, an outer plate, a rotating shaft, a hook plate, a stud, a counterweight, and a composite graphite fireproof expansion seal. The intermediate plate, the rotating shaft, and the stud are integrally formed by group welding. The interior of the sash is filled with calcium silicate fireproof board, and the outer side is covered with an outer plate formed by bending a thin plate. The intermediate plate and the outer plate are fixed by intermittent spot welding, and fireproof sealant is applied at the welding gap. The hook plate is fixed to the sash through the stud, and a counterweight is arranged on the hook plate.

[0011] Further, the hook plate cooperates with the connecting rod. When the floating ball floats upward, unlocking is formed between the hook plate and the connecting rod, and the center of gravity of the counterweight is offset to one side of the floating ball.

[0012] Further, the composite graphite fireproof expansion seal uses expanded graphite as the base material. The composite graphite fireproof expansion seal is arranged on the sash by pasting, and the composite graphite fireproof expansion seal is located between the window frame and the sash.

[0013] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0014] 1. The control method of classified sealing is adopted. The composite graphite fireproof expansion seal controls fireproof and heat insulation sealing, and the sponge rubber seal controls immersion sealing. By arranging the composite graphite fireproof expansion seal and the sponge rubber seal, the sealing requirements during fire prevention and water drainage can be effectively met.

[0015] 2. The floating ball opening device is adopted. The friction coefficient between the connecting rod and the support can be effectively reduced through the deep groove ball bearing, ensuring that the floating ball opening device can have a rapid response, accurate liquid level control for water drainage, and a simple structure.

[0016] 3. The components of the sash are fixedly connected by group welding, and fireproof sealant is applied between the gaps, which can effectively improve the sealing performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments. Embodiment 1

[0024] A passive seismic fireproof, heat-insulating and water-draining window includes an outer fixed frame 1. A window frame 2 is arranged inside the outer fixed frame 1. A window sash 3 is arranged inside the window frame 2. The window sash 3 is fixed to the window frame 2 through a rotating shaft 303 to form a rotating pair. A floating ball opening device 4 is fixed to the bottom inside the window frame 2 through bolts. The floating ball opening device 4 includes: a floating ball 401, a connecting rod 402, a support 403 and a deep groove ball bearing 404. The floating ball 401 is fixedly connected to the connecting rod 402 through a fastener. The connecting rod 402 is movably connected and fixed to the support 403 through the deep groove ball bearing 404 in cooperation with a shaft. The support 403 is connected and fixed to the window frame 2 through bolts.

[0025] The technical solutions in the embodiments of the present application at least have the following technical effects or advantages:

[0026] The overall structural strength is improved, the sealing performance is good, and the fireproof performance is excellent. The floating ball opening device 4 is adopted. The deep groove ball bearing 404 can effectively reduce the friction coefficient between the connecting rod 402 and the support 403, ensuring that the floating ball opening device 4 can have a fast response and accurate water-draining liquid level control, and the structure is simple; the classification sealing control method is adopted. The composite graphite fireproof expansion seal 307 controls the fireproof and heat-insulating seal. During a fire, the composite graphite fireproof expansion seal 307 has functions of high-temperature expansion, ablation resistance, acid and alkali resistance, high radiation resistance, heat insulation and flame retardance. The sponge rubber seal 204 controls the immersion seal. The sponge rubber seal 204 has functions of high resilience, radiation resistance and strong sealing performance. By setting the composite graphite fireproof expansion seal 307 and the sponge rubber seal 204, the requirements of fireproofing and water-draining can be effectively met. Embodiment 2

[0027] A passive seismic, fireproof, heat-insulating and water-draining window, wherein the window frame 2 comprises a frame body 201, an outer retaining strip 202, an inner retaining strip 203, a sponge rubber seal 204 and a calcium silicate fireproof board 205. The frame body 201, the outer retaining strip 202 and the inner retaining strip 203 are formed by bending thin plates and then assembled and welded. The welding gaps are fixed by intermittent spot welding, and fireproof sealant is applied at the gaps. The frame body 201 is filled with a calcium silicate fireproof board 205. Sponge rubber seals 204 are pasted on the contact surfaces of the outer retaining strip 202 and the inner retaining strip 203 with the window sash 3. The window sash 3 is limited by the inner retaining strip 203 and the outer retaining strip 202.

[0028] The window sash 3 comprises: an intermediate plate 301, an outer plate 302, a rotating shaft 303, a hook plate 304, a stud 305, a counterweight 306, and a composite graphite fireproof and expandable seal 307. The intermediate plate 301, the rotating shaft 303 and the stud 305 are formed into a whole by assembly welding. The interior of the window sash 3 is filled with a calcium silicate fireproof board 205, and the outer side is covered with an outer plate 302 formed by bending a thin plate. The intermediate plate 301 and the outer plate 302 are fixed by intermittent spot welding, and fireproof sealant is applied at the welding gaps. The hook plate 304 is fixed on the window sash 3 through the stud 305, and a counterweight 306 is arranged on the hook plate 304. The hook plate 304 cooperates with the connecting rod 402, and when the floating ball 401 floats up, an unlocking is formed between the hook plate 304 and the connecting rod 402. The composite graphite fireproof and expandable seal 307 uses expanded graphite as a base material, and the composite graphite fireproof and expandable seal 307 is arranged on the window sash 3 by pasting, and the composite graphite fireproof and expandable seal 307 is located between the window frame 2 and the window sash 3.

[0029] The components of the window sash 3 are connected and fixed by assembly welding, and applying fireproof sealant between the gaps can effectively improve the sealing performance. The sponge rubber seal 204 and the composite graphite fireproof and expandable seal 307 are used as the main components of the sealing system.

[0030] In case of a fire, when in the closed state, both the interior of the window frame 2 and the window sash 3 are filled with calcium silicate fireproof boards 205, having excellent fireproof and heat-insulating performance. The composite graphite fireproof and expandable seal 307 has functions of high-temperature expansion, ablation resistance, acid and alkali resistance, high radiation resistance, heat insulation and flame retardancy. After reaching a certain temperature, the composite graphite fireproof and expandable seal 307 pasted on the window sash 3 expands when heated, completely blocking the gap between the window frame 2 and the window sash 3. At this time, the passive seismic, fireproof, heat-insulating and water-draining window forms an airtight space, blocking the spread of hot smoke and isolating the heat on the fire side, having good fireproof performance.

[0031] The sponge rubber seal 204 controls the immersion seal. The sponge rubber seal 204 has the functions of high resilience, radiation resistance, and strong sealing performance. When an accident condition (flooding on the side of the float ball 401) occurs, under the action of buoyancy, the float ball 401 rises as the immersion liquid level continuously increases. When it reaches the designed opening liquid level, the connecting rod 402 connected to the float ball 401 forms an unlocking with the hook plate 304 installed on the window sash 3. Under the influence of the counterweight 306, the self-weight of the window sash 3, and the immersion water pressure, the window sash 3 instantaneously opens to the horizontal and remains in the horizontal state under the influence of the gravity of the counterweight 306 and the limiting effect of the outer stop strip 202 and the inner stop strip 203, so that the drainage area is maintained at the maximum. It has the advantages of high structural strength, good airtight performance, rapid response, high drainage liquid level control accuracy, and large drainage area.
