Description

Technical Field

[0001] This invention relates to the field of underground construction engineering technology, specifically to an intelligent fire-fighting floor drain device for underground smoke drainage and its usage method. Background Technology

[0002] Floor drains are widely used as a type of floor drainage device in buildings, and different types of floor drains have emerged for different fields. Fire-fighting floor drains are specifically designed for fire-fighting drainage; conventional industrial and domestic sewage is usually discharged into the sewage system without going through fire-fighting floor drains.

[0003] Patent application CN218346386U discloses a fire-fighting floor drain with odor prevention effect, including a body with an opening at the top and a drain pipe at the bottom, and an openable and closable top cover assembly at the top of the body; the body contains a garbage basket and a gravity sealing device.

[0004] While this technology improves the convenience of floor drains to some extent, it also presents several problems. First, factories, as concentrated production areas, have higher fire prevention requirements. During routine cleaning and maintenance, large amounts of water are sprayed, and existing fire-fighting floor drains are prone to water ingress, potentially affecting their use in emergencies. Second, floor drains only have a simple drainage function and cannot effectively remove smoke, especially in enclosed areas of the factory where smoke cannot be quickly expelled through windows or other passageways, posing a significant safety hazard.

[0005] In conclusion, it is necessary to improve the existing fire-fighting floor drain system. Summary of the Invention

[0006] To address the aforementioned problems, and especially the shortcomings of existing technologies, this invention provides an intelligent fire-fighting floor drain device for underground smoke drainage and its usage method, which can solve the problems of fire-fighting floor drain devices failing to start and drain smoke in non-fire situations.

A smoke sensor for monitoring the smoke situation near the floor drain smoke drainage module is installed on the top of the floor drain smoke drainage module. A smoke flow sensor for monitoring the smoke flow inside the floor drain smoke drainage module is installed inside the floor drain smoke drainage module. The blockage status of the floor drain smoke drainage module is determined by the monitoring data of the smoke sensor and the smoke flow sensor.

[0009] Furthermore, the floor drain exhaust module includes a top plate module, a filter plate, a foreign object cleaning module, and a two-stage hydraulic lifting module. The bottom of the two-stage hydraulic lifting module is provided with a first hydraulic lifting unit for lifting the top plate module, and the upper part of the two-stage hydraulic lifting module is provided with a second hydraulic lifting unit for lifting the filter plate to make it flush with the ground.

[0010] Optionally, the top plate module includes a warning top plate, a controller, a flashing warning light, and a through frame. The controller for receiving and analyzing monitoring data from the smoke sensor and the smoke flow sensor is embedded in the center of the warning top plate.

[0011] Optionally, a flashing warning light is installed on the outer ring side of the warning top plate, and a through frame that can pass through the filter plate is installed at the bottom of the warning top plate.

[0012] Optionally, the foreign object removal module includes a first drive motor, the output end of which is connected to a rotating shaft, and a second drive motor is installed on the upper part of the rotating shaft near the first drive motor.

[0013] Optionally, the output end of the second drive motor is connected to an active rotating rod, and a foreign object cleaning conveyor belt is sleeved on the active rotating rod. A transmission rotating rod is provided at the other end of the foreign object cleaning conveyor belt. The second drive motor drives the foreign object cleaning conveyor belt to move. Three sets of foreign object racks are provided on the upper part of the foreign object cleaning conveyor belt.

[0014] Optionally, the first hydraulic lifting unit includes a first support ring frame, a first hydraulic pump is installed on the upper part of the first support ring frame, a first hydraulic telescopic shaft is connected to the upper part of the first hydraulic pump, and the first hydraulic telescopic shaft passes through the filter plate and connects to the top plate module.

[0015] Optionally, the second hydraulic lifting unit includes a second support ring frame, a second hydraulic pump is mounted on the upper part of the second support ring frame, a second hydraulic telescopic shaft is connected to the upper part of the second hydraulic pump, and the top of the second hydraulic telescopic shaft is connected to a lifting ring plate fixedly disposed on the outer ring of the filter plate.

[0016] Optionally, the exhaust water pipeline includes a pipe body, one end of which is connected to the floor drain exhaust water module, and the other end is connected to an exhaust pipe at the top and a drain pipe at the bottom. A first exhaust pump and a second exhaust pump are installed on the pipe body.

[0017] Optionally, the pipe body is provided with a spray nozzle for reducing impurities, which is connected to the water supply pipeline in the water supply frame, and two sets of water pumps are provided on the water supply pipeline.

[0018] Secondly, the present invention provides a method for using the intelligent fire-fighting floor drain device for underground smoke drainage as described in the first aspect, comprising the following steps:

[0019] S1. Construction workers build a trench in the factory area according to the factory construction design requirements, and lay exhaust water pipes, water storage tanks and water conveying racks under the ground.

[0020] S2. Assemble all components of the floor drain smoke exhaust module in advance, and lay the floor drain smoke exhaust module into the groove at the factory construction site. Install the smoke sensor on the roof of the corresponding factory building.

[0021] S3. During use, the smoke sensor detects the fire situation inside the factory in real time and transmits it to the controller. When a fire produces a large amount of smoke, the controller controls the floor drain smoke drainage module to start.

[0022] S4. The first hydraulic pump starts, the first hydraulic telescopic shaft rises to open the top plate module, the filter plate is exposed for operation, and the flashing warning light flashes to warn.

[0023] S5. At the same time, the second hydraulic pump starts, and the second hydraulic telescopic shaft lifts the filter plate to be flush with the ground.

[0024] S6. The first and second exhaust pumps start to draw smoke into the exhaust water pipe. At the same time, two sets of water pumps start to spray water from the water storage tank onto the smoke through the impurity spray nozzle. Foreign objects in the smoke are discharged with the water into the drain pipe. The cleaned smoke is discharged through the exhaust pipe. It can also be used as an auxiliary device for drainage when firefighters are fighting fires.

[0025] S7. During operation, the smoke flow sensor senses the smoke flow in the floor drain exhaust module in real time. If the external smoke sensor senses that there is still a lot of mist, but the smoke flow in the floor drain exhaust module is reduced, it means that the filter plate is blocked. The debris on the upper part of the filter plate is cleaned by the foreign object cleaning conveyor belt and the foreign object removal rack, and the debris in the filter plate is cleaned by the through rack.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] 1. This invention transforms the structure of the warning top plate and filter plate in the floor drain smoke exhaust module through two sets of support ring frames and matching hydraulic telescopic shafts. Under normal circumstances, the device is in a closed state, while in the event of a fire, the device is in an activated state, thereby improving the service life of the device.

[0028] 2. This invention achieves the effect of quickly and conveniently dispersing smoke in fire areas by setting up smoke exhaust water pipelines, thereby increasing the safety of the factory.

[0029] 3. This invention uses a smoke sensor / smoke flow sensor to intelligently monitor whether the device is clogged. It relies on a foreign matter cleaning conveyor belt and a foreign matter removal rack to clean the foreign matter on the upper part of the filter plate. At the same time, the through-frame removes foreign matter from the filter plate, thereby achieving the purpose of automated cleaning of the device. Attached Figure Description

Three sets of foreign object racks 234 are provided on the upper part of the foreign object removal conveyor belt 233.

[0047] Example 2

[0048] As attached Figure 2 Appendix Figure 4 Appendix Figure 5 and attached Figure 9As shown, in one embodiment of the present invention, an intelligent fire-fighting floor drain device for underground smoke drainage, based on embodiment 1, includes a first hydraulic lifting unit 241 comprising a first support ring frame 2411, a first hydraulic pump 2412 mounted on the upper part of the first support ring frame 2411, and a first hydraulic telescopic shaft 2413 connected to the upper part of the first hydraulic pump 2412, the first hydraulic telescopic shaft 2413 penetrating the filter plate 22 and connecting to the top plate module 21; the second hydraulic lifting unit 242 includes a second support ring frame 2421, a second hydraulic pump 2422 mounted on the upper part of the second support ring frame 2421, the second hydraulic pump... The upper part of 2422 is connected to a second hydraulic telescopic shaft 2423, and the top of the second hydraulic telescopic shaft 2423 is connected to a lifting ring plate 221 fixedly installed on the outer ring of the filter plate 22; the exhaust water pipe 3 includes a pipe body 36, one end of the pipe body 36 is connected to the floor drain exhaust water module 2, and the other end is connected to an exhaust pipe 31 at the top and a drain pipe 32 at the bottom. The pipe body 36 is equipped with a first exhaust pump 33 and a second exhaust pump 34; the pipe body 36 is equipped with a dirt-reducing spray nozzle 35 inside, and the dirt-reducing spray nozzle 35 is connected to a water supply pipe 51 in the water supply frame 5. Two sets of water supply pumps 52 are installed on the water supply pipe 51.

[0049] Furthermore, regarding the working principle of this device, the construction personnel build a groove 11 in the factory area according to the factory construction design requirements, lay the exhaust water pipe 3, water storage tank 4 and water conveying frame 5 under the ground 1, assemble all the components of the floor drain exhaust water module 2 in advance, enter the factory construction site and lay the floor drain exhaust water module 2 into the groove 11, and install the smoke sensor 6 on the roof of the corresponding factory building for the floor drain exhaust water module 2.

[0050] During use, the smoke sensor 6 senses the situation inside the factory in real time and transmits it to the controller 211 for analysis. When a fire produces a large amount of smoke, the controller 211 controls the floor drain smoke drainage module 2 to start, the first hydraulic pump 2412 to start, the first hydraulic telescopic shaft 2413 to rise and open the top plate module 21, the filter plate 22 to be exposed for operation, and the flashing warning light 212 flashes to warn firefighters. The flashing warning light 212 can be used as a warning device for firefighters.

[0051] At the same time, the second hydraulic pump 2422 starts, and the second hydraulic telescopic shaft 2423 lifts up to make the filter plate 22 flush with the ground 1, which makes it easier to clean out the debris that has accumulated on the upper part of the filter plate 22 with the water flow.

[0052] Next, the first exhaust pump 33 and the second exhaust pump 34 are started to draw the smoke into the smoke exhaust water pipe 3, and the two sets of water pumps 52 are started to spray water from the water storage tank 4 through the impurity spray nozzle 35 onto the smoke, so that the smoke and foreign objects enter the drain pipe 32 with the water and are discharged. The cleaned smoke is discharged through the smoke exhaust pipe 31. It can also be used as an auxiliary device for drainage when firefighters are fighting fires.

[0053] Furthermore, during operation, the smoke flow sensor 26 monitors the smoke flow in the drain exhaust module 2 in real time. If the external smoke sensor detects that there is still a large amount of mist, but the smoke flow in the drain exhaust module 2 has decreased, it indicates that the filter plate 22 is clogged. At this time, the foreign matter cleaning module 23 is activated. The specific steps are as follows:

[0054] The first step is to start the first drive motor 237, which drives the rotating shaft 231 to rotate. The rotating shaft 231 drives the foreign object cleaning conveyor belt 233 to move in a circular motion around the first drive motor 237, collecting the debris on the filter plate 22 onto the foreign object cleaning conveyor belt 233. At the same time, the second drive motor 232 is started, which drives the active rotating rod 235 to rotate. The active rotating rod 235 drives the foreign object cleaning conveyor belt 233 to move. The foreign object cleaning conveyor belt 233 drives the transmission rotating rod 236 to rotate. The three sets of foreign object racks 234 on the upper part of the foreign object cleaning conveyor belt 233 move outward to push the debris out of the filter plate 22.

[0055] In the second step, the first hydraulic pump 2412 is started in reverse, and the first hydraulic telescopic shaft 2413 drives the through frame 213 to move downward to clean the filter plate 22, removing the debris. After cleaning, it returns to its original position to continue the smoke exhaust operation.

[0056] Example 3

[0057] This embodiment provides a method for using an intelligent fire-fighting floor drain device for underground smoke drainage as described in Embodiment 1 or Embodiment 2, the steps of which are as follows:

[0058] S1. Construction workers build a recess 11 in the factory area according to the factory construction design requirements, and lay exhaust water pipes 3, water storage tanks 4 and water conveying racks 5 under the ground 1.

[0059] S2. Assemble all components of the floor drain smoke exhaust module 2 in advance, and lay the floor drain smoke exhaust module 2 into the groove 11 at the factory construction site. Install the smoke sensor 6 on the roof of the factory corresponding to the floor drain smoke exhaust module 2.

[0060] S3. During use, the smoke sensor 6 senses the fire situation inside the factory in real time and transmits it to the controller 211. When a fire produces a large amount of smoke, the controller 211 controls the floor drain smoke drainage module 2 to start.

[0061] S4. The first hydraulic pump 2412 starts, the first hydraulic telescopic shaft 2413 rises to open the top plate module 21, the filter plate 22 is exposed for operation, and the flashing warning light 212 flashes to warn.

[0062] S5. At the same time, the second hydraulic pump 2422 starts, and the second hydraulic telescopic shaft 2423 lifts the filter plate 22 to be flush with the ground 1.

[0063] S6. The first exhaust pump 33 and the second exhaust pump 34 start to draw smoke into the smoke exhaust water pipe 3. At the same time, the two sets of water pumps 52 start to spray water in the water storage tank 4 through the impurity spray nozzle 35 onto the smoke. Foreign objects in the smoke enter the drain pipe 32 with the water and are discharged. The cleaned smoke is discharged through the smoke exhaust pipe 31. It can also be used as an auxiliary device for drainage when firefighters are fighting fires.

[0064] S7. During operation, the smoke flow sensor 26 senses the smoke flow in the floor drain smoke exhaust module 2 in real time. If the external smoke sensor 6 senses that there is still a lot of mist, but the smoke flow in the floor drain smoke exhaust module 2 has decreased, it means that the filter plate 22 is blocked. The debris on the filter plate 22 is cleaned by the foreign object cleaning conveyor belt 233 and the foreign object rack 234, and the debris in the filter plate 22 is cleaned by the through rack 213.
