Description

Technical Field

[0001] This invention relates to the field of industrial floor drain technology, specifically to a high-protection-level industrial floor drain device. Background Technology

[0002] Industrial floor drains differ from household floor drains. Industrial floor drains face more complex usage environments and challenges, especially for hazardous chemical enterprises that generate polluting wastewater and harmful gases, where the requirements for floor drain protection are much higher. According to the "Notice on Issuing the Guidelines for Safety Risk Assessment, Diagnosis and Grading of Hazardous Chemical Production and Storage Enterprises (Trial Implementation)" issued by the Ministry of Emergency Management in 2018, hazardous chemical enterprises are classified into four levels: red (below 60 points), orange (below 60 to 75 points), yellow (below 75 to 90 points), and blue (90 points and above). Based on the grading results, enterprises need to further improve their hazardous chemical safety risk protection, control, and hazard investigation. At the same time, supervision of red and orange level enterprises will be strengthened, and they will be urged to rectify problems as soon as possible in accordance with relevant national requirements. The issuance of this document undoubtedly places stricter requirements on risk protection and supervision of high-protection-level factories in my country. While industrial floor drain devices may seem insignificant, they are indispensable and a key area that hazardous chemical enterprises need to focus on when improving their protection levels.

[0003] Hazardous chemical enterprises often collect polluted wastewater from within the factory through a central pipeline for centralized treatment during wastewater discharge. Industrial floor drains, located outside the factory and connected to both the central and internal pipelines, need to prevent backflow of polluted liquids and toxic gases into the external environment, serving as a barrier. Especially in emergencies, such as leaks within the factory, a large amount of polluted liquids and toxic gases can be generated in a short time, potentially overwhelming the central pipeline and causing backflow. In such cases, industrial floor drains need to act as a buffer, maximizing isolation from the external environment to prevent polluted liquids and toxic gases from leaking into the external environment, or to provide immediate leak warnings so that personnel can address the problem promptly. Current industrial floor drain technology cannot achieve these functions, therefore, a high-protection-level industrial floor drain device is urgently needed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a high-protection-level industrial floor drain device.

[0005] This invention discloses a high-protection-level industrial floor drain device, comprising:

[0006] The main body of the drain has a storage space;

[0007] The drainage pipe connects to the containing space;

[0008] The first adsorption component is located inside the drain pipe;

[0009] The first sealing assembly includes a seal and a drain sealant. The drain sealant is located at the bottom of the receiving space, and the end of the drain pipe leaks into the drain sealant. The sealant is located in the receiving space and covers the end of the drain pipe. The open end of the sealant extends into the drain sealant.

[0010] The sensing component includes a liquid level sensor and a gas sensor arranged sequentially from bottom to top. The liquid level sensor is used to monitor the liquid level in the drain body, and the gas sensor is used to monitor whether there is leaked gas in the drain body.

[0011] The control alarm component is electrically connected to the liquid level detector and the gas sensor, respectively.

[0012] According to one embodiment of the present invention, it further includes a second adsorption component, which is disposed inside the drain body and located between the sealing element and the gas sensing element, and the cross-section of the second adsorption component is adapted to the cross-section of the drain body.

[0013] According to one embodiment of the present invention, it includes a second sealing assembly, which includes a partition, a rubber seal, and an ionic sealing liquid. The partition is disposed within the drain body and located between the seal and the gas sensor. The partition has a pressure relief port. The rubber seal covers the pressure relief port and can be detached from the partition. The ionic sealing liquid fills the space above the partition and the rubber seal, and the liquid level of the ionic sealing liquid is below the gas sensor.

[0014] According to one embodiment of the present invention, the second sealing assembly further includes an elastic connector, one end of which is connected to the seal and the other end of which is connected to the rubber seal.

[0015] According to one embodiment of the present invention, the sensing component further includes a drain fluid monitoring element, which is used to monitor the liquid level of the drain sealing fluid.

[0016] According to one embodiment of the present invention, it further includes a fluid replacement assembly, which includes a fluid replacement pipe, a fluid replacement power component, and an on / off control component. One end of the fluid replacement pipe is connected to the floor drain sealing fluid, and the other end is connected to the fluid replacement power component. The on / off control component is located in the fluid replacement pipe and controls the flow of liquid in the fluid replacement pipe.

[0017] According to one embodiment of the present invention, the first sealing assembly further includes a sealing adjustment member, which is disposed in the water pipe and connected to the sealing member, and the sealing adjustment member drives the sealing member to adjust its position in the height direction.

[0018] According to one embodiment of the present invention, it further includes a protective component, which includes a protective element and a filter element, wherein the filter element covers the opening of the drain body and the protective element covers the filter element.

[0019] According to one embodiment of the present invention, the control and warning assembly includes a control component and a warning component, wherein the control component is electrically connected to the warning component, the liquid level detection component, and the gas sensing component, respectively.

[0020] According to one embodiment of the present invention, the drain sealing fluid includes either a hydrophobic sealing fluid or a water-soluble sealing fluid.

[0021] Compared to existing technologies, when polluted wastewater from the factory flows back through the sewer pipes, small amounts of wastewater will not flow into the drain body's containment space, or a small amount of wastewater will flow into the drain body and be neutralized or absorbed by the drain sealing fluid. When the amount of wastewater is large and flows into the drain body, the liquid level inside the drain body will rise. At this time, the liquid level sensor will detect that the liquid level inside the drain body has risen to a preset critical point and will send a corresponding signal to the control alarm component. The control alarm component will then issue a warning of wastewater leakage. When toxic and harmful gases from the factory flow back through the sewer pipes, the toxic and harmful gases will be adsorbed by the first adsorption component and then isolated by the drain sealing fluid, preventing small amounts of toxic and harmful gases from entering the drain body. If the amount of toxic and harmful gases is large and flows into the drain body, it will rise and be detected by the gas sensor. At this time, the gas sensor will send a corresponding signal to the control alarm component, which will then issue a warning of toxic and harmful gas leakage. Thus, the high-protection-level industrial floor drain device of the present invention can isolate and treat backflowing polluted wastewater and toxic and harmful gases in the event of a small leak, avoiding pollution of the external environment; and in the event of a large leak, it can alert relevant personnel to take emergency measures to avoid greater safety risks.

[0028] Example 1

[0029] Reference Figure 1 and Figure 2 , Figure 1 This is a schematic diagram illustrating the application environment of the industrial floor drain device in the embodiment. Figure 2 This is a schematic diagram of a high-protection-level industrial floor drain device in the embodiment. Figure 1 As shown, the industrial floor drain device is installed on the ground outside the factory and is connected to the central pipeline via a sewer pipe. The factory interior is also connected to the central pipeline via internal factory pipes. Under normal circumstances, polluted wastewater generated inside the factory is collected in the central pipeline via the internal factory pipes and then centrally treated. However, in emergency situations such as leaks, the central pipeline cannot collect the wastewater in time, causing polluted wastewater and toxic gases to backflow into the sewer system. In the event of a small leak, the high-protection-level industrial floor drain device in this embodiment can isolate and treat the backflowed polluted wastewater and toxic gases, preventing pollution of the external environment. In the event of a large leak, the high-protection-level industrial floor drain device in this embodiment can provide timely warnings to alert relevant personnel for emergency response.

[0030] See further Figure 2The high-protection-level industrial floor drain device in this embodiment includes a floor drain body 1, a drain pipe 2, a first adsorption component 3, a first sealing component 4, a sensing component 5, and a control and alarm component 6. The floor drain body 1 has a receiving space. The drain pipe 2 is connected to the receiving space 100. The first adsorption component 3 is disposed inside the drain pipe 2. The first sealing component 4 includes a sealing element 41 and a floor drain sealing fluid 100. The floor drain sealing fluid 100 is disposed at the bottom of the receiving space, and the end of the drain pipe 2 leaks into the floor drain sealing fluid 100. The sealing element 41 is located in the receiving space and covers the end of the drain pipe 2, with its open end extending into the floor drain sealing fluid 100. The sensing component 5 includes a liquid level sensor 51 and a gas sensor 52 arranged sequentially from bottom to top. The liquid level sensor 51 is used to monitor the liquid level height inside the floor drain body 1, and the gas sensor 52 is used to monitor whether there is leaked gas inside the floor drain body 1. The control and alarm component 6 is electrically connected to both the liquid level sensor 51 and the gas sensor 52.

[0031] When polluted wastewater from inside the factory flows back through the sewer pipe, a small amount of polluted wastewater will not flow into the containment space of the drain body 1, or a small amount of polluted wastewater will flow into the drain body 1 and be neutralized or absorbed and dissolved by the drain sealing fluid 100. When the amount of polluted wastewater is large and flows into the drain body 1, it will cause the liquid level inside the drain body 1 to rise. At this time, the liquid level sensor 51 will detect that the liquid level in the drain body 1 has risen to a preset critical point and will send a corresponding signal to the control alarm component 6. The control alarm component 6 will issue a warning of polluted wastewater leakage according to the situation. When toxic and harmful gases inside the factory flow back through the sewer pipes, they are adsorbed by the first adsorption component 3 and then isolated by the drain sealing fluid 100. This prevents small amounts of toxic and harmful gases from entering the drain body 1. If a large amount of toxic and harmful gases flows into the drain body 1, it will rise and be detected by the gas sensor 52. At this time, the gas sensor 52 will send a corresponding signal to the control alarm component 6, which will issue a warning of toxic and harmful gas leakage as appropriate. Thus, the high-protection-level industrial drain device in this embodiment can isolate and treat backflowing polluted wastewater and toxic and harmful gases in the event of a small leak, preventing pollution of the external environment; and in the event of a large leak, it can alert relevant personnel to take emergency measures to avoid greater safety risks.

[0032] Specifically, the drain body 1 is embedded in the ground, with its open end exposed to the ground. The drain body 1 is cylindrical in shape. The drain pipe 2 is buried underground along a direction perpendicular to the ground, with one end extending vertically from the bottom wall of the drain body 1 into its internal space, and the other end connecting to the central pipe and the factory's internal pipes. In the event of a leak inside the factory, polluted wastewater and toxic gases will backflow into the drain pipe 2 from the central pipe and / or the factory's internal pipes.

[0033] The drain sealant 100 fills the bottom of the drain body 1, and the end of the drain pipe 2 that extends into the drain body 1 is higher than the liquid level of the drain sealant 100. In this embodiment, the drain sealant 100 can be an existing drain sealant, which can isolate gas to a certain extent and absorb wastewater to a certain extent.

[0034] In this embodiment, the first adsorption component 3 is activated carbon, which is filled inside the drain pipe 2 and close to the drain body 1. Activated carbon can adsorb toxic and harmful gases without affecting the flow of polluted wastewater. The first adsorption component 3 adsorbs and treats small amounts of leaked toxic and harmful gases to prevent them from leaking into the external environment.

[0035] In this embodiment, the sealing element 41 is a bell-shaped element, which is inverted inside the drain body 1 and covers the outside of the end of the drain pipe 2 that extends into the drain body 1. In this embodiment, the sealing element 41 is mounted on the end of the drain pipe 2 by a bracket. There is a gap between the open end of the sealing element 41 and the bottom wall of the drain body 1, and the open end of the sealing element 41 is immersed in the drain sealing liquid 100, thereby forming a sealing structure to further isolate toxic and harmful gases and prevent the leakage of toxic and harmful gases. Preferably, the gap between the open end of the sealing element 41 and the bottom wall of the drain body 1 is more than 5 cm. Thus, if the open end of the sealing element 41 is to be always immersed in the drain sealing liquid 100, the height of the drain sealing liquid 100 needs to be more than 5 cm. In practical applications, when the sealing element 41 is installed at the end of the drain pipe 2 via the bracket, the distance between the opening end of the sealing element 41 and the bottom wall of the drain body 1 needs to be set in advance. In this embodiment, the distance between the opening end of the sealing element 41 and the bottom wall of the drain body 1 is set to 5cm, and the height of the drain sealing liquid 100 is set to 15cm. At this time, the opening end of the sealing element 41 will be immersed 10cm below the drain sealing liquid 100, which can form a better sealing structure to ensure a longer sealing time and better isolate toxic and harmful gases.

[0036] In this embodiment, the liquid level sensor 51 can be an existing liquid level sensor, such as a through-beam sensor. The transmitting end is placed on the inner wall of the drain body 1 at a preset warning height, and the receiving end is placed on the outer wall of the sealing member 41, opposite to the transmitting end. When the liquid level exceeds the liquid level sensor 51, the transmitting end and the receiving end are isolated, indicating that the liquid level has reached the preset warning height. The transmitting end provides a corresponding signal to the control alarm component 6, which then issues a warning for contaminated wastewater leakage. In another embodiment, the liquid level sensor 51 can also be an existing water level sensor to directly monitor the water level inside the drain body 1; this is not limited here. In this embodiment, the liquid level sensor 51 is placed at a height of 20cm from the bottom wall of the drain body 1. When contaminated wastewater flows into the drain body 1 and causes the liquid level to rise to 20cm, the liquid level sensor 51 sends a signal to the control alarm component 6. In this embodiment, the gas sensor 52 can be an existing toxic and harmful gas sensor, which can be adapted to the different toxic and harmful gases produced by different factories, and is not limited here. The gas sensor 52 is located near the inner wall of the drain body 1 and near the opening of the drain body 1. When toxic and harmful gases rise and pass through, the gas sensor 52 detects the toxic and harmful gas leak and sends a corresponding signal to the control and warning component 6, which then controls the warning component 6 to issue a toxic and harmful gas leak warning.

[0037] Please refer to the following: Figure 3 , Figure 3 This is a control principle diagram of the control and warning component in this embodiment. Further, the control and warning component 6 in this embodiment includes a control element 61 and a warning element 62. The control element 61 is electrically connected to the warning element 62, the liquid level detector 51, and the gas sensor 52, respectively. The corresponding electrical signals from the liquid level detector 51 and the gas sensor 52 are transmitted to the control element 61. After the control element 61 makes a judgment, it sends a command to the warning element 62 to issue a corresponding warning. In this embodiment, the control element 61 can be an existing controller, and the warning element 62 can be a combination of a display and a warning light. Alternatively, it can be a buzzer or other warning device. For example, when there is a leak of polluted wastewater and / or toxic and harmful gas, the warning element 62 sends an emergency flashing light and displays red warning words. Preferably, it is combined with a buzzer alarm so that relevant personnel can notice the leak immediately and take appropriate emergency measures. In specific applications, the control element 61 and the warning element 62 can be integrated into one unit, placed in a conspicuous position on the ground, and waterproofed.

[0038] Example 2

[0039] The high-protection-level industrial floor drain device in this embodiment differs from that in Embodiment 1 in that the first sealing component 4 further includes a sealing adjustment component 42. The sealing adjustment component 42 is located in the drain pipe 2 and is connected to the sealing component 41. The sealing adjustment component 42 drives the sealing component 41 to adjust its position in the height direction. By setting the sealing adjustment component 42, the position of the sealing component 41 can be adjusted in the height direction, allowing the sealing component 41 to be installed at different preset heights. Furthermore, the distance the sealing component 41 extends below the surface of the floor drain sealing fluid 100 can be flexibly adjusted to better cooperate with the floor drain sealing fluid to form a sealing structure. In specific applications, the sealing adjustment component 42 can be a hydraulic strut. In a preferred embodiment, the sealing adjustment component 42 can also be electrically connected to the control component 61, allowing the operator to operate the control component 61 to control the sealing adjustment component 42, thereby achieving height adjustment of the sealing component 41.

[0040] Example 3

[0041] The high-protection-level industrial floor drain device in this embodiment differs from that in Embodiment 2 in that it further includes a second adsorption component 7. This second adsorption component 7 is located within the floor drain body 1, between the sealing element 41 and the gas sensing element 52. The cross-section of the second adsorption component 7 is adapted to the cross-section of the floor drain body 1. The second adsorption component 7 further adsorbs and treats toxic and harmful gases, preventing leakage into the external environment.

[0042] In this embodiment, the second adsorption component 7 is an activated carbon molded adsorption layer, which is adapted to the inner cross-section of the drain body 1 and embedded inside the drain body 1. When toxic and harmful gases flow from the inside of the drain body 1 towards the opening, the second adsorption component 7 adsorbs the toxic and harmful gases. In this way, a two-layer toxic and harmful gas adsorption structure is formed by the cooperation of the first adsorption component 3 and the second adsorption component 7, or a three-layer toxic and harmful gas adsorption structure is formed by the cooperation of the first adsorption component 3, the drain sealing liquid 100, and the second adsorption component 7. In the event of a small amount of toxic and harmful gas leakage, complete adsorption can be achieved, preventing leakage outside the drain device.

[0043] Example 4

[0044] The high-protection-level industrial floor drain device in this embodiment differs from that in Embodiment 3 in that it further includes a second sealing assembly 8. The second sealing assembly 8 includes a partition 81, a rubber seal 82, and an ion-sealing liquid 200. The partition 81 is located within the floor drain body 1, between the seal 41 and the gas sensor 52. The partition 81 has a pressure relief port 811. The rubber seal 82 covers the pressure relief port 811 and can be detached from the partition 81. The ion-sealing liquid 200 fills the space above the partition 81 and the rubber seal 82, and the liquid level of the ion-sealing liquid 200 is below the gas sensor 52. Preferably, the second sealing assembly 8 further includes an elastic connector 83, one end of which is connected to the seal 41, and the other end is connected to the rubber seal 82. A second sealing structure is formed by the combination of partition 81, rubber seal 82, and ion sealing fluid 200, thereby further blocking the risk of leakage of polluted wastewater and toxic and harmful gases and avoiding safety hazards. In particular, the combination of partition 81, rubber seal 82, and ion sealing fluid 200 to form a second sealing structure, together with the second sealing structure formed by seal 41 and drain sealing fluid 100, can isolate the leakage of small amounts of polluted wastewater and also help adsorb toxic and harmful gases.

[0045] Specifically, the partition 81 is a partition embedded in the inner wall of the drain body 1 and located above the seal 41. The pressure relief port 811 is located in the middle of the partition 81. The rubber seal 82 is a rubber plug that covers the pressure relief port 811. The ion sealing liquid 200 is liquid and fills the space above the partition 81, pressing it against the outer surface of the rubber seal 82. This stabilizes the rubber seal 82 on the pressure relief port 811. Furthermore, because the ion sealing liquid 200 has poor fluidity, it will not enter the pressure relief port 811 through the gap between the rubber seal 82 and the partition 81, thus avoiding any impact on other internal components of the drain device 1.

[0046] Ion sealant 200 is a hydrophobic ionic liquid, primarily used to isolate rainwater and other water flows from the outside. Due to its hydrophobic properties and higher density than water, water flowing in from the outside remains on the surface of ion sealant 200 and cannot penetrate it. Therefore, it cannot enter the interior of the drain body 1, thus preventing it from affecting the adsorption, protection, and sealing of the drain sealant 100 inside the drain body 1. The water layer on top of the ion sealant 200 floats on its surface under normal conditions. Since it does not enter the drain device, even if water overflows, it will not affect the environment or enter the factory through the drain device. As the water layer gradually evaporates and dries up with environmental changes, the lower layer of ion sealant 200, due to its extremely low vapor pressure, remains non-volatile, allowing for long-term use. This reduces the frequency of replacement and maintenance, improving the reliability and convenience of the device. In this embodiment, the ion sealing fluid 200 is composed of tributylmethylammonium bis(trifluoromethanesulfonyl)imide salt.

[0047] In addition, the ion sealing fluid 200 can be replaced according to different usage scenarios, and while achieving the purpose of sealing, it can also adsorb toxic and harmful gases. For example, when 1-hexyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide salt is used as the ion sealing fluid 200, this type of ion sealing fluid 200 can adsorb sulfides and can be used in some factories that prepare sulfides to prevent toxic and harmful sulfides from leaking out through the floor drain.

[0048] The rubber seal 82 isolates the ion sealing liquid 200 from the interior of the drain body 1 below, so that the interior of the drain device is not affected by the external environment, and at the same time ensures that the liquid or gas inside the drain device will not leak into the external environment and cause a leakage accident.

[0049] In this embodiment, the elastic connector 83 is an elastic strut that passes through the pressure relief port 811. Its two ends are vertically connected to the rubber seal 82 and the seal 41, respectively. When a large amount of polluted wastewater or toxic gas leaks, the internal space of the drain body 1 becomes completely filled with gas or liquid, resulting in extremely high pressure. This internal pressure causes the elastic connector 83 to rise, opening the rubber seal 82 and achieving pressure relief. Furthermore, the ion-sealing liquid 200 on the rubber seal 82 acts as a buffer during pressure relief, neutralizing the harmfulness of the leaked toxic gases or liquids and minimizing their impact on the external environment. In the case of small-scale leaks, where the gas and liquid pressure inside the drain body 1 has not reached a critical value, the elastic connector 83 will not rise and the rubber seal 82 will not open. This ensures that the gas or liquid flowing back from the sewer pipe remains only in the internal space of the drain body 1 and does not leak into the external environment, thus preventing a leak accident.

[0050] In addition, the rubber seal 82 opens due to the high pressure rise. After a period of pressure relief, the pressure it receives will gradually decrease. At this time, due to the elastic properties of the elastic connector 83, the rubber seal 82 will reset, thereby cutting off the leakage process and reducing the leakage time.

[0051] Example 5

[0052] The difference between the high-protection-level industrial floor drain device in this embodiment and that in Embodiment 4 is that the floor drain sealing fluid 100 includes either a hydrophobic sealing fluid or a water-soluble sealing fluid.

[0053] The main components of the hydrophobic sealing fluid include: 95% by weight of polydimethylsiloxane, 99.9% purity, 1000 cst viscosity; 3% by weight of 1-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide salt, 99% purity; 2% by weight of glycerol, 99% purity; and 0.1% by weight of barium disilicate phosphor.

[0054] The main components of the water-soluble sealing fluid include: 90% glycerol (99% purity); 5% ethyl 1-ethyl-3-methylimidazolium sulfate (95% purity); 3% water; 2% caprolactam tetrabutylammonium bromide (95% purity); and 0.1% barium disilicate phosphor.

[0055] In this embodiment, fluorescent powder is added to both the hydrophobic and water-soluble sealing liquids. In actual use, the presence of fluorescent reaction in the external environment can be monitored at any time to determine whether the drain device is properly sealed and whether there is any leakage of the sealing liquid, thus enhancing the warning effect.

[0056] Preferably, in this embodiment, the water-soluble sealing fluid further includes propylene glycol, sulfolane, methyl diethanolamine, ethyl 1-butyl-3-methylimidazolium sulfate, 1-butyl-3-methylimidazolium bromide, or 1-butyl-3-methylimidazolium acetate to replace ethyl 1-ethyl-3-methylimidazolium sulfate and caprolactam tetrabutylammonium bromide. The proportions of each component can also be adjusted according to actual conditions to absorb hazardous components in polluted wastewater and / or toxic and harmful gases, further reducing the risk of leakage.

[0057] Example 6

[0058] The high-protection-level industrial floor drain device in this embodiment differs from that in Embodiment 5 in that: preferably, the sensing component 5 further includes a floor drain liquid monitoring element (not shown in the figure), which is used to monitor the liquid level of the floor drain sealing fluid 100. The high-protection-level industrial floor drain device also includes a fluid replacement component 9, which includes a fluid replacement pipe 91, a fluid replacement power component 92, and an on / off control component 93. One end of the fluid replacement pipe 91 is connected to the floor drain sealing fluid 100, and the other end is connected to the fluid replacement power component 92. The on / off control component 93 is located in the fluid replacement pipe 91 and controls the flow of liquid within the fluid replacement pipe 91.

[0059] Understandably, once a leak occurs, the drain sealant 100 becomes contaminated with wastewater and / or toxic and harmful gases, rendering it unusable and necessitating replacement. Therefore, the drain sealant needs to be replaced. A drain sealant monitoring device is used to monitor the level of the drain sealant 100 inside the drain body 1, allowing relevant personnel to monitor its level at any time and facilitating its replacement.

[0060] In practical applications, the drain fluid monitoring device can be a level sensor, which is electrically connected to the control unit 61. When the drain sealing fluid 100 is lower than the preset warning level, the drain fluid monitoring device sends a signal to the control unit 61. The control unit 61 displays the actual situation of the drain sealing fluid 100 to remind relevant personnel to replace the drain sealing fluid. In this embodiment, the drain fluid monitoring device is the level detection device 51.

[0061] When replacing the drain sealant 100, the operator opens the on / off control 93 to allow the fluid replacement pipe 91 to flow. Then, the fluid replacement power unit 92 replenishes the drain sealant 100 into the drain body 1. Alternatively, the residual drain sealant in the drain body 1 can be removed first, and then new drain sealant 100 can be added. In this embodiment, the on / off control 93 is a valve, and the fluid replacement power unit 92 is a water pump.

[0062] Example 7

[0063] The difference between the high-protection-level industrial floor drain device in this embodiment and that in Embodiment 6 is that the high-protection-level industrial floor drain device further includes a protective component 10, which includes a protective element 101 and a filter element 102. The filter element 102 covers the opening of the floor drain body 1, and the protective element 101 covers the filter element 102.

[0064] The protective component 101 and the filter component 102 are designed to prevent external debris from contaminating the interior of the drain body 1. The filter component 102 is a filter screen, with its cross-section adapted to the opening of the drain body 1, thus filtering out external debris and preventing it from entering the drain. The protective component 101 is a cover with a water inlet, which covers or encloses the filter component 102 to protect it. Preferably, the protective component 101 also includes a dust cover and a water baffle. The dust cover and water baffle are integrally enclosed outside the drain device to prevent external debris such as leaves and stones from accumulating on the cover and causing potential blockages. In specific applications, the dust cover and water baffle can use existing structures and are not limited here.

[0065] In summary, the high-protection-level industrial floor drain device of the present invention can isolate and treat backflowing polluted wastewater and toxic and harmful gases in the event of a small leak, thus preventing pollution of the external environment; and in the event of a large leak, it can alert relevant personnel to take emergency measures to avoid greater safety risks.

[0066] The above description is merely an embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of the claims of the present invention.
