Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
FIG. 1a is a schematic diagram of the structure of a sealing device in one embodiment. The sealing device 100 includes: an outer sleeve 110, an inner sleeve 120, a connecting member 130, and a sealing flap 140.
Wherein the outer sleeve 110 comprises two ports: an external first port 111 and an external second port 112, the external first port 111 being connected to a sewer line; the inner sleeve 120 is located inside the outer sleeve 110, and is connected to the outer sleeve 110, and the inner sleeve 120 includes two end surfaces: an inner first end face 121 and an inner second end face 122, the inner first end face 121 being proximate to the outer first port 111 and the inner second end face 122 being proximate to the outer second port 112; the connecting member 130 is in force connection with the inner sleeve 110 through the inner second end surface 122; the sealing baffle 140 is located at the outer second port 112 and connected to the connecting member 130 for sealing the outer second port 112.
Specifically, as shown in fig. 1a, the outer sleeve 110 has a hollow cylindrical structure with two open ends, and the port of the outer sleeve 110 may be circular, square or other shape, and may be specifically determined according to the shape of the mouth of the sewer pipe to be connected, so that the external first port 111 of the outer sleeve 110 is matched and connected with the mouth of the sewer pipe.
Further, the inner sleeve 120 is a hollow cylindrical structure with two closed ends, and the end surface of the inner sleeve 120 may be circular, square or any other shape, so as to ensure that the inner sleeve 120 is hollow to accommodate the connecting part 130, thereby avoiding the damage caused by long-term exposure of the connecting part 130 to a humid environment, which results in the failure of the sealing function of the entire sealing device. The outer sleeve 110 and the inner sleeve 120 can be connected to the outer sleeve 110 and the inner sleeve 120 by providing a filter net at the outer first port 111 and connecting the filter net with the outer sleeve 110 and the inner sleeve 120 through hot melt adhesive, so as to connect the outer sleeve 110 and the inner sleeve 120, wherein the filter net can be used for filtering water flowing into a sewer.
Further, one end of the connecting member 130 passes through the inner second end surface 122 to be connected to the inner sleeve 120 under a force, and the other end of the connecting member 130 is connected to the sealing baffle 140, so as to attach the sealing baffle 140 to the inner second end surface 122. The forced connection is a connection mode that each connection object is subjected to an acting force exerted by the other connection object. After the original stress is changed by the external force, the original connection state between the connection objects is also changed, and after the external force disappears and the original stress is restored, the original connection state between the connection objects can be restored. For example, two magnet pieces are connected through magnetic attraction, and the two magnets are separated by external force. And in the interaction range of the magnetic attraction of the two magnets, the external force disappears, and then the two magnets recover the original stress, so that the original connection relationship is recovered, and the connection is changed from disconnection.
Wherein, one end of the connecting part 130 connected to the inner sleeve 120 may be provided with a horizontal protrusion to prevent the connecting part 130 from falling off from the inner sleeve 120. The connecting member 130 and the sealing baffle 140 may be connected by hot melt or mechanically, for example, an external thread is provided at one end of the connecting member 130 connected to the sealing baffle 140, an internal thread matching the external thread is provided in the sealing baffle 140, and the connecting member 130 and the sealing baffle 140 are connected by the internal and external threads.
Further, the sealing baffle 140 is a plate-shaped structure, and the shape and size of the sealing baffle 140 are not particularly limited, so as to completely cover the outer second port 112.
Alternatively, the outer sleeve 110, the inner sleeve 120, and the sealing baffle 140 may be made of a metal material, such as iron, copper, aluminum, or stainless steel alloy, a resin material, such as polyvinyl chloride (pvc), ABS (acrylonitrile-butadiene-styrene copolymer) engineering plastic, or an inorganic non-metal material, such as ceramic. In this regard, the present embodiment is not particularly limited. When the outer sleeve 110, the inner sleeve 120 and the sealing baffle 140 are made of metal materials, the sealing baffle can be obtained by stamping forming; when the outer sleeve 110/the inner sleeve 120/the sealing baffle 140 are made of resin material, it can be obtained by injection molding.
In this embodiment, the outer sleeve 110, the inner sleeve 120, and the sealing baffle 140 are preferably made of a lightweight, corrosion resistant, impact resistant stainless steel alloy. The coupling member 130 is made of a magnet, and is coupled to the magnet located in the inner sleeve 120 by a magnetic attraction force, thereby coupling the coupling member 130 to the inner sleeve 120.
With reference to fig. 1a and 1b, the operation of the sealing device 100 is as follows:
the outer first port 111 of the outer sleeve 110 is connected to the end of the sewer pipe to receive the flow of water in the sewer pipe.
When no water flows through the sewer pipe, the connecting part 130 is connected with the inner sleeve 140 through magnetic attraction between magnets, the sealing cover plate 140 is tightly attached to the outer second port 112 under the action of the connecting part 130, and completely covers the outer second port 112, that is, the sealing cover plate 140 is in a closed state (fig. 1a), so that when no water flows through the sewer pipe, the air flow inside and outside the sewer pipe is blocked.
When water is slowly passed through the sewer pipe, the water flows through the region between the outer sleeve 110 and the inner sleeve 120. Due to the low initial water flow and the low flow rate, the force applied to the sealing flap 140 is less than the magnetic attraction between the connecting member 130 and the inner sleeve 140, and is not enough to change the connection between the connecting member 130 and the inner sleeve 120, and the sealing flap 140 is still in the closed state (fig. 1 a). When the sealing device 100 is connected with a sewer pipe longitudinally or obliquely, water flow is converged in the sealing device 100, the gravity of the water flow acts on the sealing cover plate 140, and the connecting part 130 is subjected to the gravity of the water flow due to the fixed connection of the sealing cover plate 140 and the connecting part 130. When the water flow converges to a certain amount, the gravity of the water flow received by the connecting part 130 is greater than the magnetic attraction force between the connecting part 130 and the inner sleeve 140, so that the connecting part 130 is disconnected from the inner sleeve 120, and the connecting part 130 drives the sealing cover 140 to be away from the outer second port 112, i.e. the sealing cover 140 is in an open state (fig. 1 b). The water flows out of the sealing device, so that the water in the sewer pipeline is discharged. As the water flow passing through the sewer pipe is reduced to zero, the gravity of the water flow received by the connecting part 130 is gradually smaller than the magnetic attraction between the connecting part 130 and the inner sleeve 140, the connecting part 130 and the inner sleeve 140 are reconnected by the magnetic attraction, and the connecting part 130 drives the sealing cover plate 140 to approach and cling to the external second port, that is, the sealing cover plate is restored to the closed state (fig. 1 a).
When water flows through the sewer pipe rapidly and the acting force on the sealing baffle 140 generated by the rapid water flows is greater than the magnetic attraction force between the connecting part 130 and the inner sleeve 120, the connecting part 130 is disconnected from the inner sleeve 120, so that the sealing cover 140 is in an open state (fig. 1 b). And as the flow rate of the water flowing through the sewer pipe is gradually reduced to zero, the acting force of the flow rate of the water flowing through the connecting part 130 is smaller than the magnetic attraction force between the connecting part 130 and the inner sleeve 120, the connecting part 130 and the inner sleeve 120 are reconnected through the magnetic attraction force, and the sealing cover plate is restored to the closed state (fig. 1 a).
In this embodiment, the sealing device includes an outer sleeve, an inner sleeve, a connection member, and a sealing baffle, where the connection member is in stressed connection with the inner sleeve, so that the sealing baffle is tightly attached to the outer second port of the outer sleeve, thereby achieving a sealing effect of the sealing device. The water flow in the sewer pipe enters the sealing device through the first external port of the external sleeve, the stress state between the connecting part and the internal sleeve is changed through the water flow gravity, the connecting state between the connecting part and the internal sleeve is further changed, the connecting part drives the sealing baffle to be opened, water is drained, when the water flow is reduced, the stress state between the connecting part and the internal sleeve is recovered due to the reduction of the water flow gravity, the connecting state between the connecting part and the internal sleeve is also recovered, and the connecting part drives the sealing baffle to be closed. The sealing device not only realizes the free discharge of water flow in the sewer pipe, but also avoids the air flow diffusion caused by opening of the pipe mouth, thereby further causing the virus diffusion, improving the closure of the sewer pipe and reducing the possibility of spreading infection sources on floors through the drainage pipe.
In one embodiment, the connecting member is an elastic element, one end of the elastic element passes through the inner second end surface to be connected with the inner sleeve, and the other end of the elastic element is connected with the sealing baffle.
Wherein, the elastic element refers to an element which has elastic properties and can be restored after limited stretching, such as rubber and a spring. The extension length of the elastic element in the sealing device is larger than the natural length of the elastic element, so that the elastic element is in stressed connection with the inner sleeve through the elastic element.
As shown in fig. 2a, in the present embodiment, the elastic element in the sealing device 200 is a spring 230.
