Description

Technical Field

[0001] This invention relates to the field of sewage discharge technology, and in particular to a self-sealing sewage discharge device and discharge method. Background Technology

[0002] In the power generation process, there are numerous pipelines in the workshop, including many drainage pipes. Drainage valves are typically installed at the lowest points of these pipes. Under normal operating conditions, a continuous flow of drainage water exits from these valves. For drainage water that is not recycled, it is generally discharged directly into the sewage network through these valves. Given my country's climate, in winter, when the units are shut down or the drainage pipes contain a large amount of water, the pipes are prone to freezing as temperatures drop, thus affecting normal drainage. In summer, when the units are shut down, the drainage water in the pipes can easily breed mosquitoes, affecting the air quality in the workshop. In residential environments, due to limited space, the impact of floor drains cannot be ignored. During normal use, drainage should be ensured to be smooth. When not in use for extended periods, sewage pipes should be well isolated from the indoor environment to prevent the breeding of mosquitoes, thus preventing mosquitoes from entering the house.

[0003] Based on the characteristics of existing industrial or household floor drains, water seals or mechanical seals are generally used. Water seals rely entirely on water for isolation within factory buildings or indoor spaces. When left unused for extended periods, the water in the drain comes into contact with the air in the outside environment, allowing mosquitoes and other insects bred from the wastewater to directly enter the room or factory; or, due to prolonged disuse, the water in the drain system evaporates completely, and the drain loses its sealing function. Both of these phenomena cause varying degrees of pollution to the factory or indoor environment.

[0004] Therefore, the technical problem with existing technology is that when a standalone water seal or mechanical seal floor drain system is not in use, it loses its sealing function, which can easily lead to the breeding of mosquitoes and affect the indoor environment. Summary of the Invention

[0005] To address the problem that individual water-sealed or mechanically sealed floor drain systems lose their sealing function when idle, easily leading to mosquito breeding and affecting the indoor environment, this invention provides a self-sealing drainage device that achieves self-sealing through a dynamic balancing mechanism using a seesaw, thus preventing mosquito breeding and environmental impact.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0007] A self-sealing sewage discharge device, comprising:

[0008] A flow guide tube is used to receive and filter wastewater.

[0009] The cover is located on the top surface of the guide tube and is movably connected to the top surface of the guide tube.

[0010] A partition plate is arranged in the inner cavity of the flow guide cylinder, the top surface of the partition plate is in contact with the bottom surface of the cover body, a sewage window is arranged on the upper portion of the partition plate, and a communication hole is arranged on the lower portion of the partition plate.

[0011] A bottom plate is fixedly connected to the bottom surface of the flow guide cylinder, the bottom surface of the partition plate is fixedly connected to the surface of the bottom plate, the partition plate is used for dividing the inner cavity of the flow guide cylinder into a first cavity and a second cavity, the sewage window is used for guiding the sewage entering the flow guide cylinder into the first cavity during sewage discharge, and the first cavity and the second cavity discharge the sewage to the sewage pipe network through the communication hole in a seesaw dynamic balance mode.

[0012] Compared with the prior art, the present application has the following advantages: when the sewage needs to be discharged, the filtered sewage enters the second cavity of the flow guide cylinder and is guided into the first cavity by the sewage window of the partition plate, and the first cavity and the second cavity discharge the sewage to the sewage pipe network in a seesaw dynamic balance mode; when the sewage does not need to be discharged, the flow guide cylinder is sealed by the first cavity and the second cavity in a seesaw dynamic balance mode to form a self-sealing structure, so as to prevent the breeding of mosquitoes after contacting the sewage pipe and affecting the environment, and ultimately achieve the purpose of providing a good external environment regardless of whether the sewage is discharged or not.

[0013] Further preferably, the flow guide cylinder comprises:

[0014] A cylinder body, the top surface of the cylinder body is movably connected to the bottom surface of the cover body.

[0015] A drainage hole is arranged on the side wall of the cylinder body and is used for guiding the sewage to the sewage pipe network.

[0016] A sealing plate is arranged on the inner side wall of the cylinder body and is slidably connected to the bottom plate, and is used for shielding the drainage hole to prevent the odor of the sewage pipe network from entering the second cavity and affecting the environment, or is used for opening the drainage hole by sliding to discharge the sewage.

[0017] When the sewage is not discharged, the sealing plate shields the drainage hole by sliding to prevent the odor of the sewage pipe network from contacting the indoor environment along the second cavity and breeding mosquitoes to affect the environment, and the sealing cylinder is realized. When the sewage is discharged, the sealing plate opens the drainage hole by sliding to ensure smooth discharge of the sewage.

[0018] Further preferably, the first cavity is respectively provided with:

[0019] A sealing assembly is arranged in the lower portion of the first cavity and is fixedly connected to the inner wall of the cylinder body, and is used for sealing the space between the first cavity and the bottom plate, and when the sewage entering the first cavity overflows the sealing assembly, the sealing assembly is used for discharging the sewage to the second cavity by breaking the seal.

[0020] The seesaw assembly is connected with the sealing assembly at one end, passes through the partition plate and is located in the second cavity at the other end, and is rotationally connected with the partition plate, and is used for rotating in the second cavity by the buoyancy of the sewage when the sealing assembly discharges the sewage to the second cavity, so as to balance the flow of the sewage in the first cavity and the second cavity.

[0021] By adopting the technical scheme, the sewage entering the second cavity enters the seesaw assembly from the sealing assembly, and the seesaw assembly balances the sewage from the first cavity to the second cavity by the action of the dynamic seesaw, so that the purpose of dynamically and quantitatively discharging the sewage is achieved.

[0022] Further preferably, the seesaw assembly comprises:

[0023] The balancing piece is arranged in the partition plate and is rotationally connected with the inner wall of the partition plate.

[0024] The horizontal rod is located in the first cavity at one end and passes through the balancing piece and is located in the second cavity at the other end, and the balancing piece is used for balancing the weight of the two ends of the horizontal rod by rotation.

[0025] The seesaw rod is connected with one end of the horizontal rod at one end and is connected with the sealing assembly at the other end, and is used for driving the sealing assembly to move up and down to break the sealing and discharge the sewage or seal the sealing assembly.

[0026] The float rod is connected with the other end of the horizontal rod at one end and is located in the second cavity, and is used for driving the horizontal rod to rotate counterclockwise under the action of the buoyancy of the sewage.

[0027] The floating ball is embedded in the sealing plate and is fixedly connected with the other end of the float rod, and the outer wall of the floating ball is matched with the inner wall of the sealing plate, and is used for transmitting the buoyancy to the float rod.

[0028] By adopting the technical scheme, when the amount of sewage in the second cavity gradually increases, the floating ball will contact the sewage, the floating ball will move upward under the action of the buoyancy of the sewage, and the float rod will drive the horizontal rod to rotate counterclockwise around the balancing piece, when the amount of sewage in the second cavity decreases, the buoyancy gradually decreases, the floating ball will move downward due to gravity, and the float rod will drive the horizontal rod to rotate clockwise, so that the balancing piece can reciprocate in the partition plate. When the horizontal rod is horizontal, it indicates that the amount of sewage in the first cavity and the second cavity is the same or there is no sewage, so that the purpose of discharging sewage by the seesaw type is achieved.

[0029] Further preferably, the sealing assembly comprises:

[0030] The water leakage plate is located in the first cavity and is arranged on the inner wall of the cylinder body and is matched with the inner wall.

[0031] The sealing barrel is connected with the bottom surface of the water leakage plate at the top surface, and is used for containing the sewage.

[0032] A water leakage rod is arranged inside the sealed barrel and connected with the seesaw at one end.

[0033] A tray is fixed with the bottom surface of the sealed barrel, and the other end of the water leakage rod is fixed with the bottom surface of the tray. The water leakage rod is used to pull the seesaw to move towards the bottom plate under the action of gravity of the sewage in the sealed barrel, so as to discharge the sewage from the sealed barrel.

[0034] A water leakage hook is fixed on the bottom surface of the water leakage plate.

[0035] A tray hook is arranged on the tray and fixed with the upper surface of the tray.

[0036] A telescopic part is connected with the water leakage hook at one end and connected with the tray hook at the other end, and is used to follow the sealed barrel to discharge sewage by stretching, or to follow the sealed barrel to return to the water leakage plate by contraction.

[0037] According to the above technical scheme, when there is no sewage in the barrel, the seesaw assembly is in a horizontal state, the sealed barrel is in contact with the water leakage plate, which is used to divide the first sealed cavity into two parts that are not communicated, thereby preventing the odor of the second cavity from flowing back from the first cavity. When sewage enters the first cavity from the second cavity, it flows through the water leakage plate and enters the sealed barrel. As the water level in the sealed barrel rises, the amount of sewage increases. Under the gravity of the sealed barrel and the weight of the sewage, the sealed barrel gradually moves away from the water leakage plate and towards the bottom plate. At the same time, the sealed barrel elongates the spring, and the sewage automatically flows through the bottom plate after overflowing from the sealed barrel.

[0038] Further optimization is that the second cavity is respectively provided with:

[0039] A filter assembly is located at the upper part of the second cavity and is adapted with the inner wall of the barrel, and is used to filter the sewage entering the barrel.

[0040] A water blocking assembly is located below the filter assembly and has a distance between the filter assembly and the inner wall of the barrel, and is adapted with the inner wall of the barrel, and is used to block the filtered sewage from entering the second cavity, so that the sewage flows along the partition plate into the first cavity.

[0041] According to the above technical scheme, the sewage entering the barrel is first filtered by the filter assembly to block impurities, so as to prevent the first cavity or the second cavity from being blocked. The filtered sewage enters the water blocking assembly, and the water blocking assembly blocks the flow of the sewage to the partition plate, and then enters the second cavity.

[0042] Further optimization is that the filter assembly comprises:

[0043] A filter plate is adapted with the inner wall of the barrel at one side wall and adapted with the side wall of the partition plate at the other side wall, and is used to filter the sewage entering the barrel.

[0044] The first support is fixed on the inner wall of the cylinder body, and the surface of the first support abuts against the bottom surface of the filter plate, so as to limit the position of the filter plate in the second cavity.

[0045] By adopting the technical scheme, the filter plate can be stably connected to the cylinder body.

[0046] Further, the water blocking assembly comprises:

[0047] The baffle is arranged below the first support and has a distance between the first support, one side wall of the baffle is matched with the inner wall of the cylinder body, and the other side wall is matched with the side wall of the partition plate, so as to block the filtered sewage to the partition plate, so that the sewage is introduced to the first cavity by the partition plate.

[0048] The second support is fixedly connected with the inner wall of the cylinder body, and the surface of the second support abuts against the bottom surface of the baffle, so as to limit the position of the baffle.

[0049] By adopting the technical scheme, the baffle can be stably connected to the cylinder body.

[0050] The application further discloses a sewage discharging method of the self-sealing sewage discharging device.

[0051] S901, the sewage enters the second cavity of the cylinder body.

[0052] S902, the filter assembly filters the sewage to obtain filtered sewage.

[0053] S903, the water blocking assembly blocks the filtered sewage to the partition plate.

[0054] S904, the partition plate introduces the filtered sewage into the first cavity.

[0055] S905, the filtered sewage enters the sealing assembly.

[0056] S906, the sealing assembly introduces the filtered sewage from the first cavity into the second cavity by the formula of dynamic balance of the seesaw, and contacts the floating ball.

[0057] S907, after the floating ball is subjected to the buoyancy of the filtered sewage, the sealing plate is driven to open the drain hole to discharge the filtered sewage.

[0058] By adopting the technical scheme, the sewage is first filtered by the filter assembly to remove the blocking impurities, then the sewage is blocked by the water blocking assembly to the partition plate, introduced into the second cavity by the partition plate, and discharged from the cylinder body by the seesaw of the seesaw assembly, and when there is no sewage, the self-sealing effect is achieved.

[0059] Further, the formula of dynamic balance is:

[0060] G1+G2+F-G3≥4kx.

[0061] Wherein, G1 is the weight of the sealing barrel in the sealing assembly, G2 is the weight of the sewage entering the sealing barrel, G3 is the weight of the floating ball in the rocker assembly, F is the buoyancy of the floating ball, and kx is the tension of the spring in the sealing assembly.

[0062] According to the above technical scheme, when G1+G2+F-G3>4kx, the rocker assembly continues to rotate counterclockwise, the amount of sewage increases, and G1+G2+F-G3=4kx, which indicates that the amount of sewage discharged from the barrel is equal to the amount of sewage entering the barrel, and the normal drainage stage is entered.

DETAILED DESCRIPTION

[0069] According to the characteristics of existing industrial production or household floor drains, water seals or mechanical seals are generally used. For water seal factory buildings or indoor spaces, complete isolation is relied on water. When idle for a long time, the standing water in the floor drain contacts with the air in the external environment, and the mosquitoes breeding in the sewage directly enter the indoor or factory building; or due to long-term idle, the water in the floor drain system evaporates completely, and the floor drain loses the sealing effect; both of the above phenomena cause different degrees of pollution to the factory building or indoor environment.

[0070] Therefore, the technical problem existing in the prior art is that the single water seal or mechanical seal floor drain system loses the sealing effect when idle, which is easy to breed mosquitoes and affect the indoor environment.

[0071] In view of the above technical problems, the present application is designed and conceived as follows:

[0072] Under normal operating conditions, the valve on the drain pipe and the floor drain are normally working; when the unit is shut down, especially during the unit shutdown for overhaul, the shutdown time is relatively long, a single-cylinder self-unloading anti-blocking anti-odor anti-mosquito breeding device is provided, which can automatically open the sewer passage when the sewage passes through the device, and automatically adjust the opening of the sewer valve according to the water weight and self-sealing capacity, then adjust each mechanism into normal sewer state with the increase of water volume, and finally seal the system and cut the sewer pipe and the external environment when the sewer is finished. Ultimately, whether there is drainage or not, it can play a role in sewerage and cutting, so as to provide a good external environment.

[0073] The present application will be further described in detail below in combination with the accompanying drawings. Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 .

[0074] A self-sealing sewerage device, as shown in the drawings, comprises: Figure 1

[0075] A flow guide cylinder 1 is used for receiving and filtering sewage. Specifically, the top of the flow guide cylinder 1 in the embodiment is in a half-open state, one half is closed, and the other half is open and used for accessing sewage.

[0076] A cover body 4 is arranged on the top surface of the flow guide cylinder 1 and movably connected with the top surface of the flow guide cylinder 1, covering the flow guide cylinder 1 and closing one half of the top surface of the flow guide cylinder 1, so that the sewage enters the flow guide cylinder 1 only from the open part of the flow guide cylinder 1.

[0077] A partition plate 5 is arranged in the internal cavity of the flow guide cylinder 1, the top surface of the partition plate 5 is in contact with the bottom surface of the cover body 4, a sewer window 51 is arranged on the upper part of the partition plate 5, and a communication hole 52 is arranged on the lower part of the partition plate 5. After the sewage enters from the sewer window 51, it flows into the left side of the flow guide cylinder 1, and then enters the right side from the communication hole 52 at the bottom of the left side of the flow guide cylinder 1.

[0078] ​The bottom plate 8 is fixed to the bottom surface of the flow guide cylinder 1, and the bottom surface of the partition plate 5 is fixed to the surface of the bottom plate 8. The partition plate 5 is used to divide the internal cavity of the flow guide cylinder 1 into a first cavity and a second cavity. The first cavity is located on the left side of the partition plate 5, and the second cavity is located on the right side of the partition plate 5. When sewage is discharged, the sewage inlet window 51 is used to guide the sewage entering the flow guide cylinder 1 into the first cavity. The first cavity and the second cavity are connected through the communication hole 52 to discharge the sewage to the sewage pipe network through the seesaw dynamic balance. In this way, a communicating vessel is formed on the left and right sides of the partition plate 5, and the sewage is gradually discharged from the flow guide cylinder 1 in a dynamic balance state according to the principle of the communicating vessel. When there is no sewage to be discharged, the flow guide cylinder 1 is balanced through the seesaw, and the second cavity is separated from the sewage pipe network.

[0079] When it is necessary to discharge sewage, the filtered sewage enters the second cavity of the flow guide cylinder 1 and is guided by the sewage inlet window 51 of the partition plate 5 into the first cavity. The first cavity and the second cavity discharge the sewage to the sewage pipe network through the seesaw dynamic balance. When there is no need to discharge sewage, the first cavity and the second cavity seal the flow guide cylinder 1 through the seesaw dynamic balance to form a self-sealing to prevent the breeding of mosquitoes after contacting with the sewage pipe and affecting the environment. Finally, the purpose of providing a good external environment regardless of whether there is no hydrophobic can be achieved.

[0080] Specifically, as shown in Figure 1 and Figure 3 , the flow guide cylinder 1 in the embodiment includes:

[0081] The cylinder body 11 is movably connected to the bottom surface of the cover body 4. Specifically, the cover body 4 covers the top surface of the partition plate 5. When there is no sewage, the cover body 4 is rotated to block the open part of the cylinder body 11 to prevent dust or impurities in the environment from depositing on the cylinder body 11 and affecting the reuse effect of the cylinder body 11. In a specific implementation, the cover body 4 can be a telescopic cover body 4. When it is necessary to discharge sewage, the cover body 4 is retracted to the closed part of the cylinder body 11. When there is no need to discharge sewage, the cover body 4 can be extended to block the open part of the cylinder body 11.

[0082] The drain hole 13 is provided on the side wall of the cylinder body 11 and is used to guide the sewage to the sewage pipe network. Specifically, the shape of the drain hole 13 can be any one of a frame type, a honeycomb type, and a rice character type, Figure 1 and Figure 3 The drain hole 13 in the frame type is used.

[0083] The sealing plate 12 is provided on the inner side wall of the cylinder body 11. The top surface of the sealing plate 12 is fan-shaped, the longitudinal section is L-shaped, the outer wall is in contact with the inner wall of the cylinder body 11, and the sealing plate 12 is slidably connected to the bottom plate 8. When the floating ball 65 moves up and down, the sealing plate 12 moves up and down to block the drain hole 13 to prevent the odor of the sewage pipe network from entering the second cavity, or to open the drain hole 13 by sliding to discharge the sewage.

[0084] When no sewage is discharged, the sealing plate 12 blocks the drain hole 13 by sliding, preventing the sewage pipe network from affecting the environment by contacting the indoor environment and breeding mosquitoes, and achieving the function of the sealing cylinder 11. When sewage is discharged, the sealing plate 12 is opened by sliding, ensuring smooth discharge of sewage.

[0085] Specifically, the first cavity in the embodiment is provided with:

[0086] A sealing assembly 7 is located at the lower part of the first cavity and is fixed to the inner wall of the cylinder 11, used to seal the space between the first cavity and the bottom plate 8. When the sewage entering the first cavity overflows the sealing assembly 7, the sealing assembly 7 is used to discharge the sewage to the second cavity by breaking the seal.

[0087] A seesaw assembly 6 is connected to the sealing assembly 7 at one end and passes through the partition plate 5 and is located in the second cavity at the other end, and is rotationally connected with the partition plate 5. When the sealing assembly 7 discharges sewage to the second cavity, it is used to rotate in the second cavity by the buoyancy of the sewage, balancing the flow of sewage in the first cavity and the second cavity.

[0088] The sewage entering the second cavity enters the seesaw assembly 6 from the sealing assembly 7. The seesaw assembly 6 discharges the sewage from the first cavity to the second cavity by the action of dynamic seesaw balance, achieving the purpose of dynamic quantitative discharge of sewage.

[0089] Specifically, as shown in Figure 1 and Figure 2 The seesaw assembly 6 in the embodiment includes:

[0090] A balancing member 64 is provided in the partition plate 5, with its planar side wall in contact with the inner wall of the sewer window 51, and its central axis rotationally connected with the sewer window 51 and the inner wall of the partition plate 5. In a specific implementation, the balancing member 64 is in the shape of a bead, and a crossbar 61 has one end located in the first cavity and the other end passing through the balancing member 64 and located in the second cavity, with the balancing member 64 used to balance the weight of the two ends of the crossbar 61 by rotating.

[0091] A seesaw rod 62 has one end connected with one end of the crossbar 61 and the other end connected with the sealing assembly 7, used to drive the sealing assembly 7 to move up and down, thereby forming a seesaw structure with the crossbar 61 to break the seal and discharge sewage or seal the sealing assembly 7.

[0092] A float rod 63 has one end connected with the other end of the crossbar 61 and is located in the second cavity, used to push the crossbar 61 to rotate counterclockwise under the action of the buoyancy of the sewage.

[0093] The floating ball 65 is embedded in the sealing plate 12 and is fixed to the other end of the floating rod 63. The outer wall of the floating ball 65 is matched with the inner wall of the sealing plate 12, and is used to transmit the received buoyancy to the floating rod 63. In the specific implementation, the floating ball 65 is a hollow ball, which is easily moved upward by the buoyancy of the sewage and drives the sealing plate 12 to open the drain hole 13, so as to quickly drain the sewage and improve the sensitivity of the seesaw assembly 6, thereby improving the sewage draining efficiency.

[0094] When the sewage does not enter the cylinder 11, the cross rod 61 is in a horizontal state, the floating rod 63 and the seesaw rod 62 are in a horizontal state on both sides of the cross rod 61, the middle part of the floating ball 65 is embedded in the sealing plate 12, the sealing plate 12 blocks the drain hole 13, and the first cavity and the second cavity are in a sewage-free water balance state.

[0095] When the sewage enters and gradually flows into the second cavity, the floating ball 65 contacts the sewage, and the floating ball 65 is moved upward by the buoyancy of the sewage, and drives the floating rod 63 to move upward, and the floating rod 63 drives the cross rod 61 to rotate counterclockwise around the balance piece 64. When the amount of sewage in the second cavity decreases, the buoyancy gradually decreases, and the floating ball 65 moves downward due to gravity, and drives the floating rod 63 to move downward, and further drives the cross rod 61 to rotate clockwise. In this way, the balance piece 64 can reciprocate in the partition plate 5. When the cross rod 61 is in a horizontal state, it indicates that the sewage in the first cavity and the second cavity is the same or there is no sewage, so as to achieve the purpose of draining sewage by the seesaw type.

[0096] Specifically, as shown in Figure 1 and Figure 4 , the sealing assembly 7 in the embodiment includes:

[0097] The water leakage plate 71 is located in the first cavity and is arranged on the inner wall of the cylinder 11 and is matched with the inner wall. The sealing barrel 77 is connected with the bottom surface of the water leakage plate 71, and is used to contain sewage. The geometric center of the water leakage plate 71 is provided with a water leakage hole, and the sewage enters the sealing barrel 77 from the water leakage hole and gradually fills the sealing barrel 77.

[0098] The third support 70 is fixed to the inner wall of the cylinder 11 and is located at the bottom of the water leakage plate 71 and abuts against the bottom surface of the water leakage plate 71, and is used to support and limit the position of the water leakage plate 71 in the first cavity and the inner wall of the cylinder 11, so that the connection between the water leakage plate 71 and the cylinder 11 is more stable.

[0099] The water leakage rod 76 is arranged in the inside of the sealing barrel 77, and one end of the water leakage rod 76 is connected with the seesaw rod 62.

[0100] A tray 75 is fixed coaxially with the bottom surface of the sealed barrel 77, and the other end of the water leakage rod 76 is fixed with the bottom surface of the tray 75. The water leakage rod 76 is used to pull the rocker towards the bottom plate 8 under the action of gravity of the sewage in the sealed barrel 77, so as to discharge the sewage in the sealed barrel 77.

[0101] A water leakage hook 72 is fixed on the bottom surface of the water leakage plate 71.

[0102] A tray hook 74 is arranged on the tray 75 and fixed with the upper surface of the tray 75. The diameter of the tray 75 is larger than that of the sealed barrel 77, so that the tray hook 74 can be completely fixed on the tray 75. The telescopic piece 73 is connected with the water leakage hook 72 at one end and connected with the tray hook 74 at the other end, and is used to follow the sealed barrel 77 to discharge sewage by stretching, or to follow the sealed barrel 77 to restore to the water leakage plate 71 by contraction. The number of the tray hook 74 is the same as that of the water leakage hook 72 and the telescopic piece 73, so that the telescopic piece 73 can be connected with the tray hook 74 and the water leakage hook 72.

[0103] When there is no sewage in the barrel 11, the rocker assembly 6 is in a horizontal state, the sealed barrel 77 is in contact with the water leakage plate 71, and is used to divide the first sealed cavity into two parts, thereby preventing the odor of the second cavity from flowing back from the first cavity. When sewage enters the first cavity from the second cavity, it flows through the water leakage plate 71 and enters the sealed barrel 77. As the water level in the sealed barrel 77 rises, the amount of sewage increases. Under the gravity of the sealed barrel 77 and the weight of the sewage, the sealed barrel 77 gradually moves away from the water leakage plate 71 and towards the bottom plate 8, while the spring is elongated. After the sewage overflows the sealed barrel 77, it automatically flows through the bottom plate 8.

[0104] Specifically, the second cavity in the embodiment is respectively provided with:

[0105] A filter assembly 3 is located in the upper part of the second cavity and is adapted with the inner wall of the barrel 11, and is used to filter the sewage entering the barrel 11.

[0106] A water blocking assembly 2 is located below the filter assembly 3 and has a distance with the filter assembly 3, and is adapted with the inner wall of the barrel 11, and is used to block the filtered sewage from entering the second cavity, so that the sewage flows into the first cavity along the partition plate 5.

[0107] The sewage entering the barrel 11 is first filtered by the filter assembly 3 to block impurities, so as to prevent the first cavity or the second cavity from being blocked. The filtered sewage enters the water blocking assembly 2, and the water blocking assembly 2 blocks the flow of the sewage to the partition plate 5, and then enters the second cavity.

[0108] Specifically, the filter assembly 3 in the embodiment includes:

[0109] A filter plate 31 is adapted to the inner wall of the cylinder 11 on one side and to the side wall of the partition plate 5 on the other side, and is used to filter the sewage entering the cylinder 11. The filter plate 31 is in the form of a screen, so that it can block the blocking impurities from entering the second cavity.

[0110] A first support 32 is fixed to the inner wall of the cylinder 11, and the surface thereof is in abutment with the bottom surface of the filter plate 31, and is used to define the position of the filter plate 31 in the second cavity. The first support 32 can be a support block, which can be welded to the inner wall of the cylinder 11, and can stably connect the filter plate 31 to the cylinder 11.

[0111] Specifically, the water blocking assembly 2 in the embodiment includes:

[0112] A baffle 21 is arranged below the first support 32 and has a distance between the first support 32, and the baffle 21 is adapted to the inner wall of the cylinder 11 on one side and to the side wall of the partition plate 5 on the other side, and is used to block the filtered sewage to the partition plate 5, so that the sewage is introduced to the first cavity by the partition plate 5. In a specific implementation, the surface of the baffle 21 is flush with the bottom surface of the sewer window 51, so that the sewage can be completely blocked to the sewer window 51.

[0113] A second support 22 is fixed to the inner wall of the cylinder 11, and the surface thereof is in abutment with the bottom surface of the baffle 21, and is used to define the position of the baffle 21, and can stably connect the baffle 21 to the cylinder 11.

[0114] The application further discloses a sewage discharging method of the self-sealing sewage discharging device, as shown in the drawings, which comprises the following steps: Figure 5

[0115] S901 After the sewage enters the left second cavity of the cylinder 11, the sewage flows through the filter assembly 3.

[0116] S902 The filter assembly 3 blocks the blocking impurities on the filter plate 31, so as to filter the sewage and obtain filtered sewage, and the filtered sewage flows from the filter plate 31 to the water blocking assembly 2.

[0117] S903 The baffle 21 of the water blocking assembly 2 blocks the filtered sewage to the sewer window 51 of the partition plate 5.

[0118] S904 The partition plate 5 introduces the filtered sewage into the first cavity. Specifically, the filtered sewage flows into the first cavity from the sewer window 51.

[0119] S905 The filtered sewage enters the sealing assembly 7. Specifically, the filtered sewage flows through the leakage plate 71, and then enters the sealing barrel 77 through the leakage hole of the leakage plate 71.

[0120] ​S906 With the gradual increase of the amount of sewage in the sealed barrel 77, the sealed barrel 77 gradually leaves the water leakage plate 71 and loses the sealing effect, when the sewage overflows the sealed barrel 77 and flows on the bottom plate 8, and gradually enters the second cavity through the communication hole 52, when the water level in the second cavity rises and contacts the floating ball 65, at this time the whole sealing assembly 7 guides the filtered sewage from the first cavity to the second cavity through the seesaw dynamic balance effect, and contacts the floating ball 65.

[0121] S907 The floating ball 65 is subjected to the buoyancy of the filtered sewage, which drives the sealing plate 12 to leave the drain hole 13, opens the drain hole 13, and discharges the filtered sewage.

[0122] The above technical scheme is adopted, the sewage is first filtered by the filtering assembly 3, and the blocking impurities are removed, then the water blocking assembly 2 blocks the flow of the sewage to the partition plate 5, and the partition plate 5 is introduced into the second cavity, and the sewage is discharged from the cylinder 11 by the seesaw effect of the seesaw assembly 6, and when there is no sewage, it plays a self-sealing role.

[0123] Specifically, the dynamic balance formula in the embodiment is:

[0124] G1+G2+F-G3≥4kx.

[0125] Wherein, G1 is the weight of the sealed barrel 77 in the sealing assembly 7, G2 is the weight of the sewage entering the sealed barrel 77, G3 is the weight of the floating ball 65 in the seesaw assembly 6, F is the buoyancy of the floating ball 65, and kx is the tension of the spring in the sealing assembly 7. When G1+G2+F-G3>4kx, the seesaw assembly 6 continues to rotate counterclockwise, the amount of sewage increases, G1+G2+F-G3=4kx, which means that the amount of sewage discharged from the cylinder 11 is equal to the amount of sewage entering the cylinder 11, and the normal drainage stage is entered.

[0126] Please combine Figures 1-5 , the sewage discharge process is described as follows:

[0127] The sewage first flows through the filter assembly 3 of the second cavity, and the filter plate 31 blocks the blocking impurities mixed therein on the filter plate 31 to obtain filtered sewage. The filtered sewage flows through the water blocking assembly 2, and the baffle 21 blocks the flow to the drain window 51 of the partition plate 5, and then flows along the drain window 51 into the first cavity, and then passes through the water leakage plate 71 into the sealed barrel 77. With the increase of the sewage amount, the filtered sewage gradually fills the sealed barrel 77 and overflows from the sealed barrel 77. At this time, the sealed barrel 77 starts to move downward, away from the water leakage plate 71, and then loses the sealing effect. At the same time, the filtered sewage flows through the bottom plate 8 and enters the second cavity through the communication hole 52. With the increase of the sewage amount in the second cavity, the floating ball 65 is in contact with the sewage and is acted on by the buoyancy of the sewage to move upward, thereby pushing the floating rod 63 to move upward, and then pushing the horizontal rod 61 to rotate counterclockwise, and at the same time driving the sealing plate 12 to move to gradually open the drain hole 13 to drain the filtered sewage to the sewage pipe network. With the continuous increase of the sewage amount, when G1+G2+F-G3>4kx, the flap assembly 6 continues to rotate counterclockwise, and the amount of discharged sewage increases. When G1+G2+F-G3=4kx, it means that the amount of sewage discharged from the cylinder 11 is equal to the amount of sewage entering the cylinder 11, and the normal drainage stage is entered.

[0128] The specific embodiment is only an explanation of the application, and is not a limitation of the application. Those skilled in the art can make modifications to the embodiment without creative contribution after reading the specification, as long as the modifications are within the protection scope of the application.
