Abstract
Description
Technical Field
[0001] This utility model relates to the field of drainage pipe technology, specifically an indoor monitoring device for drainage pipes. Background Technology
[0002] Building drainage systems typically use a single drainpipe in the kitchen or bathroom, running from the top floor through all floors to the basement or open space. After connecting elbows, the drainpipe slopes horizontally through the building's exterior wall and connects to an outdoor sewage well. Indoor sewage is discharged outdoors through this pipe. During subsequent renovations and use by the homeowner, construction waste or other reasons can cause excessive accumulation of insoluble debris in the pipe, leading to blockages. Once a blockage forms, the accumulated sewage can overflow, overflowing from the floor drain or drain outlet of the lowest-floor apartment using the pipe, causing significant damage to the homeowner's property.
[0003] Existing technology typically involves extending two parallel drainage pipes from the bottom of an existing drainage riser. After passing through the building's exterior wall, both pipes (which can be installed vertically or horizontally parallel) are connected together to an outdoor sewage well. Monitoring the water level inside the drainage pipe using a level switch indoors can optimize the handling of blockages. However, in practical applications, because the level switch is fixed inside the drainage pipe to a pipe cap, and the wire end needs to be away from the liquid surface with the wire extending from the top of the drain end, the pipe cap needs to be removed to clean the inside of the pipe when cleaning it. This makes it difficult to maintain continuous monitoring of the liquid level inside the drainage pipe by the level switch. Summary of the Invention
[0004] To overcome the shortcomings of the prior art, this application provides an indoor monitoring device for a drainage pipe. By fastening a pipe cap with a meniscus cover and a liquid level switch to the top of the monitoring branch pipe, when the pipe cap is connected to the monitoring branch pipe and one end of the liquid level switch extends into the interior of the monitoring branch pipe, the observation port can be exposed to the field of view by controlling the meniscus cover to rotate around its hinge point with the pipe cap. This allows for observation of the blockage inside the monitoring branch pipe, achieving the technical effect of maintaining continuous monitoring of the liquid level inside the monitoring branch pipe by the liquid level switch without having to directly remove the pipe cap from the top of the monitoring branch pipe.
[0005] The technical solution adopted by the embodiments of this application to solve its technical problem is:
[0006] An indoor monitoring device for a drainage pipe includes a pipe cap, a level switch, and a monitoring branch pipe. The level switch passes through the inside of the pipe cap from top to bottom and is assembled and fixed thereto.
[0007] An observation port is provided inside one side of the pipe opening cover, and the observation port is covered with a meniscus cover. A drain pipe is assembled and connected to one side of the monitoring branch pipe.
[0008] The half-meniscus cover is hinged to the pipe opening cover at the top of the observation port, and the pipe opening cover is fastened to the top of the monitoring branch pipe, so that one end of the liquid level switch extends into the interior of the monitoring branch pipe.
[0009] Preferably, a protective net is assembled and connected to the top inner wall of the pipe cap. One end of the protective net extends into the interior of the monitoring branch pipe, and its side is in contact with the inner wall of the monitoring branch pipe, so that the part of the liquid level switch extending into the monitoring branch pipe is between the protective net and the inner wall of the monitoring branch pipe.
[0010] Preferably, the inner side of the pipe cap is provided with a locking structure, and a limiting post is machined on the bottom surface of the meniscus cap near the hinge point between it and the pipe cap. The locking structure cooperates with the limiting post inside the pipe cap to restrict the rotation of the meniscus cap around the hinge point between it and the pipe cap.
[0011] Preferably, the locking structure includes two symmetrically arranged locking plates, and the inner side of one end of each locking plate is integrally formed with a protruding arc plate; the inner side of the protruding arc plate abuts against the bottom side of the limiting post, restricting the rotation of the meniscus cover around its hinge point with the pipe opening cover.
[0012] Preferably, the two locking plates are connected at both ends and formed into a ring by a connecting buckle.
[0013] Preferably, both locking plates pass through the inside of the pipe cap, and the two locking plates are supported by a groove inside the pipe cap that matches the locking plates for rotation.
[0014] Preferably, the two connecting buckles are respectively fastened to the two ends of the two locking plates, and one connecting buckle is attached to the inside of the pipe cap and the other connecting buckle is attached to the outside of the pipe cap to control the angle of rotation of the locking plates inside the pipe cap.
[0015] Preferably, the top of the monitoring branch pipe is provided with an installation slot, and when the pipe cap is fastened to the top of the monitoring branch pipe, the two locking plates are located inside the installation slot.
[0016] In summary, this utility model has at least one of the following beneficial technical effects:
[0017] Firstly, this utility model discloses an indoor monitoring device for drainage pipes. By fastening a pipe cap with a meniscus cover and a liquid level switch to the top of the monitoring branch pipe, when the pipe cap is connected to the monitoring branch pipe and one end of the liquid level switch extends into the interior of the monitoring branch pipe, the observation port can be exposed to the field of vision by controlling the rotation of the meniscus cover around its hinge point with the pipe cap. This allows for observation of the blockage inside the monitoring branch pipe without having to directly remove the pipe cap from the top of the monitoring branch pipe, thus maintaining continuous monitoring of the liquid level inside the monitoring branch pipe by the liquid level switch.
[0018] Secondly, the indoor monitoring device for drainage pipes of this utility model has a locking structure inside the pipe opening cover, which is assembled from two locking plates and two connecting buckles. With the help of the locking structure set on the surface of the bottom of the meniscus cover and the support of the protruding arc plate on the inner side of the locking plate, it is convenient to determine whether the meniscus cover can rotate around the hinge point between it and the pipe opening cover as needed.

[0025] Example 1:
[0026] An indoor monitoring device for drainage pipes, such as Figures 1-3 As shown, it includes a pipe cap 2, a liquid level switch 3 and a monitoring branch pipe 4. An observation port 6 is opened inside one side of the pipe cap 2. The observation port 6 is covered by a meniscus cover 5. A drain pipe 1 is assembled and connected to one side of the monitoring branch pipe 4.
[0027] In this process, by passing the liquid level switch 3 through the inside of the pipe cap 2 from top to bottom and assembling and fixing it thereto, and by hingedly connecting one side of the meniscus cover 5 to the position of the pipe cap 2 at the top of the observation port 6, when the pipe cap 2 is fastened to the top of the monitoring branch pipe 4, one end of the liquid level switch 3 can be inserted into the inside of the monitoring branch pipe 4 to monitor the water level inside the monitoring branch pipe 4.
[0028] Meanwhile, when it is necessary to visually inspect the inside of the monitoring branch pipe 4 and to perform simple sewage discharge with the help of tools, the meniscus cover 5 can be controlled to rotate around its hinge point with the pipe opening cover 2 to open the observation port 6, thereby providing an observation channel and keeping the bottom of the liquid level switch 3 always inside the monitoring branch pipe 4.
[0029] Secondly, to prevent foreign objects clogging the drain pipe 1 from sticking to the surface of the float at the bottom of the level switch 3 via the monitoring branch pipe 4, such as... Figure 2 and Figure 3 As shown, a protective net 9 is assembled and connected to the top inner wall of the pipe cap 2. By extending one end of the protective net 9 into the interior of the monitoring branch pipe 4 and having its side attached to the inner wall of the monitoring branch pipe 4, the part of the liquid level switch 3 extending into the monitoring branch pipe 4 is kept between the protective net 9 and the inner wall of the monitoring branch pipe 4. This allows the protective net 9 to isolate foreign objects and avoid affecting the normal function of the liquid level switch 3.
[0030] This utility model discloses an indoor monitoring device for a drainage pipe. By fastening a pipe cap 2 with a half-moon plate cover 5 and a liquid level switch 3 to the top of the monitoring branch pipe 4, when the pipe cap 2 is connected to the monitoring branch pipe 4 and one end of the liquid level switch 3 extends into the interior of the monitoring branch pipe 4, a protective net 9 can be used to form a protective barrier on the inside of the monitoring branch pipe 4 and outside the liquid level switch 3 to prevent blockages from sticking to the surface of the liquid level switch 3 and affecting the function of the liquid level switch 3 in monitoring the liquid level.
[0031] Meanwhile, when it is necessary to observe the blockage inside the monitoring branch pipe 4, the observation port 6 can be exposed to the field of view by controlling the meniscus cover 5 to rotate around its hinge point with the pipe end cover 2. This eliminates the need to directly remove the pipe end cover 2 from the top of the monitoring branch pipe 4 and maintain the continuous monitoring of the liquid level inside the monitoring branch pipe 4 by the liquid level switch 3. It also does not affect the need to remove the pipe end cover 2 from the top of the monitoring branch pipe 4 and remove the liquid level switch 3 from inside the monitoring branch pipe 4.
[0032] Example 2:
[0033] Based on Example 1, such as Figures 3-5As shown, this embodiment is a limiting structure for the meniscus cover 5. A locking structure 7 is provided on the inner side of the pipe opening cover 2. A limiting post 8 is processed on the bottom surface of the meniscus cover 5 near the hinge point between it and the pipe opening cover 2. The locking structure 7 includes two symmetrically arranged locking plates 702. A protruding arc plate 703 is integrally formed on the inner side of one end of each of the two locking plates 702.
[0034] In this way, by having the inner side of the protruding arc plate 703 abut against the bottom side of the limiting post 8, the locking structure 7 can be supported inside the pipe cover 2 and cooperate with the limiting post 8 to restrict the rotation of the meniscus cover 5 around its hinge point with the pipe cover 2.
[0035] Secondly, by connecting the two ends of the two locking plates 702 together and forming a ring by connecting buckles 701, and by fastening the two buckles 701 to the two ends of the two locking plates 702 respectively, and by using one buckle 701 on the inside of the pipe cap 2 and the other buckle 701 on the outside of the pipe cap 2, the angle of rotation of the locking plates 702 inside the pipe cap 2 can be controlled, so as to facilitate the operation of whether the protruding arc plate 703 abuts against the side of the limiting post 8.
[0036] Meanwhile, by having both locking plates 702 pass through the inside of the pipe cap 2, the two locking plates 702 can be rotated by the slots inside the pipe cap 2 that are adapted to the locking plates 702.
[0037] Furthermore, the top of the monitoring branch pipe 4 is provided with an installation slot 10. By fastening the pipe cap 2 to the top of the monitoring branch pipe 4, the two locking plates 702 are located inside the installation slot 10, which does not affect the connection between the pipe cap 2 and the top of the monitoring branch pipe 4, and does not affect the rotation of the locking plates 702 inside the installation slot 10 and the pipe cap 2.
[0038] This utility model discloses an indoor monitoring device for a drainage pipe. By setting a locking structure 7 (the locking structure 7 is in a circular state) inside the pipe opening cover 2, which is assembled from two locking plates 702 and two connecting buckles 701, the locking structure 7 located on the bottom surface of the semi-meniscus cover 5 can be supported and cooperated with the protruding arc plate 703 on the inner side of the locking plate 702 to restrict the semi-meniscus cover 5 from rotating around its hinge point with the pipe opening cover 2, so as to keep the pipe opening cover 2 in a closed state of the top of the monitoring branch pipe 4.
[0039] When it is necessary to open the meniscus cover 5, simply control the connecting buckle 701 on the outside of the pipe opening cover 2 to drive the two locking plates 702 to rotate inside the pipe opening cover 2, which is simple and convenient.
[0040] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
