Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipe fittings, and more specifically, to a drainage pipe with a blockage warning function. Background Technology
[0002] With the continuous acceleration of urbanization in my country, the construction of municipal sewage pipeline projects is an indispensable and fundamental link in urban development. Drainage systems are essential infrastructure for modern cities and are also the backbone of urban water pollution prevention, drainage, flood control, and flood prevention. Among them, the investment in rainwater and sewage pipeline systems in residential areas and industrial and mining enterprises generally accounts for about 70% of the total investment in drainage systems.
[0003] During use, sewage pipes may become blocked due to the accumulation of sludge, pipe aging, and other reasons. Once blocked, sewage drainage will slow down or even stop, which will seriously affect the lives of users. Therefore, designing a pipe with a blockage warning function is of great practical significance.
[0004] Existing methods for detecting blockages in drainage pipes typically involve installing level sensors on the pipes to determine if they are blocked. However, relying solely on level sensors provides only one criterion, which is not accurate enough. Sometimes, rapid changes in water flow speed or temperature within the pipe can cause the level sensors to misjudge, wasting time on repairs. Utility Model Content
[0005] The purpose of this invention is to overcome the problem that the existing drainage pipes rely on a single criterion for determining whether they are blocked, which is prone to misjudgment. This invention provides a drainage pipe with a blockage warning function, which uses more diverse criteria to determine whether a blockage is present, thereby reducing the misjudgment rate.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A drainage pipe with a blockage warning function is provided, including a pipe body with an internal water flow channel, a liquid level sensor, a clamping device, and a vibration detection device installed on the clamping device. The side wall of the pipe body has a liquid level detection port communicating with the water flow channel. The liquid level sensor is installed in the liquid level detection port. The clamping device is clamped to the outer wall of the pipe body. The signal output terminal of the liquid level sensor is used to connect to a signal receiving module, and the signal output terminal of the vibration detection device is used to connect to the signal receiving module.
[0007] This utility model discloses a drainage pipe with a blockage warning function. A liquid level sensor is installed inside the liquid level detection port. When the pipe is in normal use, the liquid level value sensed by the sensor is within the normal range. When the pipe is blocked or the water flow is obstructed, the water column formed inside the pipe will rise, and the liquid level value sensed by the sensor will increase sharply. Therefore, the liquid level signal can be used as one criterion for whether the pipe is blocked. A vibration detection device can emit a sine wave into the pipe and receive the reflected signal. Since blockage changes the flow state of the fluid inside the pipe and the pipe's own vibration characteristics, the vibration signal can be used as another criterion for whether there is a blockage. The signal output terminals of both the liquid level sensor and the vibration detection device are connected to a signal receiving module. By combining these two signals, a blockage can be identified when both a sudden rise in liquid level and a large fluctuation in vibration signal are detected simultaneously. If only one signal fluctuates, further observation is needed. By monitoring the entire process through feedback from both signals, early warnings can be provided, allowing for timely repairs and preventing further blockage or disruption of normal drainage. Compared to existing technologies that use only one signal as a criterion, this solution uses a combination of liquid level and vibration signals as the criterion for determining whether a blockage has occurred. This provides a more diverse range of judgment angles, reduces the probability of misjudgment, and improves accuracy. Since the outer wall of the main pipe is relatively thick, it is difficult to install fasteners. Therefore, the vibration detection device is installed on a clamping device and then clamped to the pipe body, which facilitates the installation of the vibration detection device.
[0008] Furthermore, the clamping device includes an arc-shaped first clamping block and an arc-shaped second clamping block, the first clamping block and the second clamping block being detachably connected, and the vibration detection device being connected to either the first clamping block or the second clamping block. The first clamping block and the second clamping block are designed to be detachable for easy replacement or repair in case of damage.
[0009] Furthermore, the first clamping block has a first protrusion and a second protrusion at both ends, respectively. A first locking tooth is provided on one side of the first protrusion, and a second locking tooth is provided on one side of the second protrusion. The second clamping block has a first step and a second step at both ends, respectively. A first slot is provided within the first step, and a second slot is provided within the second step. The first protrusion is installed within the first step, and the first locking tooth engages with the first slot. The second protrusion is installed within the second step, and the second locking tooth engages with the second slot. The engagement of the first locking tooth within the first slot and the engagement of the second locking tooth within the second slot achieves the fixation between the first and second clamping blocks. Compared to traditional threaded connections, this structure improves connection strength, reduces the risk of backing out, and ensures no loosening or abnormal noise issues during long-term use.
[0010] Furthermore, the first clamping block has a groove, and the vibration detection device is fixed in the groove by fasteners.
[0011] Furthermore, both the first clamping block and the second clamping block are made of PVC material. PVC material has a certain degree of elasticity. By compressing the first clamping block, the first locking tooth engages with the first locking slot, and the second locking tooth engages with the second locking slot. After this, the first clamping block springs back, resulting in a better fixing effect between the first and second clamping blocks.
[0012] Furthermore, the liquid level sensing device is a piezoresistive liquid level sensor.
[0013] Furthermore, at least two annular protrusions are provided on the inner wall of any port of the main pipe body, and these protrusions are used to abut against the outer wall of the outer pipe fitting. By using these protrusions to abut against the outer wall of the outer pipe fitting, the sealing and tightness of the pipeline are improved.
[0014] Furthermore, the main body of the pipe has several injection ports, located between two annular protrusions at the same port, and connected to the inner wall of the main body. Previously, adhesive was applied to the inner wall of the main body before installing the outer fitting. However, the rolled edge at the port of the outer fitting would scrape away some of the adhesive, resulting in an unstable connection. In this solution, when the outer fitting is installed at the port of the main body, the outer wall of the outer fitting, the two adjacent annular protrusions, and the inner wall of the main body form a sealed injection cavity. After installation, the operator can inject adhesive from the outside of the fitting into the injection cavity through the injection port. The adhesive fills the entire injection cavity, improving the sealing and tightness of the connection.
[0015] Furthermore, an inwardly inclined guide is provided at the port of the main pipe body. This provides guidance when the outer pipe fitting is inserted into the port of the main pipe body, improving convenience.
[0016] Furthermore, the main body of the pipeline can be a straight pipe, a bend, or a tee pipe.
[0017] Compared with the prior art, the beneficial effects of this utility model are: 1. Compared with existing technologies, this solution uses a combination of liquid level signals and vibration signals as the criteria for determining whether a blockage has occurred. This provides a more diverse range of judgment angles, reduces the probability of misjudgment, and improves accuracy. Since the outer wall of the main pipe is relatively thick, it is difficult to install fasteners. Therefore, the vibration detection device is installed on the clamping device and then clamped onto the main pipe body, which facilitates the installation of the vibration detection device. 2. The first and second clamping blocks are connected by teeth and grooves. Compared with the traditional threaded connection, the connection strength of this structure is improved, the risk of backing is reduced, and there are no loosening or abnormal noise problems after long-term use. 3. The inner wall of the pipe fitting body is provided with a first protrusion and a second protrusion, and the outer wall is provided with an injection port. After the outer pipe fitting is inserted, an injection cavity is formed inside. The operator can inject glue from the outside of the pipe fitting body into the injection cavity through the injection port. The glue fills the entire injection cavity, improving the sealing and tightness of the connection. Attached Figure Description

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.
[0024] Example 1 This embodiment provides a drainage pipe with a blockage warning function, such as... Figure 1 As shown, the device includes a pipe body 100 with an internal water flow channel, a liquid level sensing device 200, a clamping device 300, and a vibration detection device 400 installed on the clamping device 300. In this embodiment, the pipe body 100 is a bend, the liquid level sensing device 200 is a piezoresistive liquid level sensor, and the side wall of the pipe body 100 has a liquid level detection port 110 connected to the water flow channel at the bend. The liquid level sensing device 200 is installed inside the liquid level detection port 110, and the clamping device 300 is clamped to the outer wall of the pipe body 100. The signal output terminal of the liquid level sensing device 200 is used to wirelessly connect to the signal receiving module, and the signal output terminal of the vibration detection device 400 is used to wirelessly connect to the signal receiving module.
[0025] The working principle of this embodiment is as follows: This utility model discloses a drainage pipe with a blockage warning function. A liquid level sensor 200 is installed inside the liquid level detection port 110. When the pipe is in normal use, the liquid level value sensed by the liquid level sensor 200 is within the normal range. When the pipe is blocked or the water flow is obstructed, the water column formed inside the pipe will increase, and the liquid level value sensed by the liquid level sensor 200 will rise sharply. Therefore, the liquid level signal can be used as one of the criteria for whether the pipe is blocked. A vibration detection device 400 can emit a sine wave to the pipe and receive the reflected signal. Since blockage will change the flow state of the fluid in the pipe and the vibration characteristics of the pipe itself, the vibration signal can be used as another criterion for whether there is a blockage. The signal output terminals of the liquid level sensor 200 and the vibration detection device 400 are both connected to a signal receiving module. By combining these two signals, when a sharp rise in the liquid level value and a large fluctuation in the vibration signal are detected at the same time, it can be determined that a blockage has occurred. If only one signal fluctuates, more observation or step-by-step troubleshooting can be carried out to achieve full monitoring, early warning and early maintenance, and avoid further blockage or blockage affecting normal drainage.
[0026] The beneficial effects of this utility model are as follows: Compared to existing technologies that use only one signal as a criterion, this scheme uses a combination of liquid level signal and vibration signal as a criterion for whether there is a blockage. This provides more diverse judgment angles, reduces the probability of misjudgment, and improves accuracy. Since the outer wall of the main body of the pipeline 100 is relatively thick, it is difficult to install fasteners. Therefore, the vibration detection device 400 is installed on the clamping device 300 and then clamped to the pipeline body, which facilitates the installation of the vibration detection device 400.
[0027] Example 2 This embodiment is a second embodiment of a drainage pipe with a blockage warning function. This embodiment is similar to the first embodiment, except that, as shown in the following... Figure 2As shown, the clamping device 300 includes an arc-shaped first clamping block 310 and an arc-shaped second clamping block 320. The first clamping block 310 and the second clamping block 320 are detachably connected. The first clamping block 310 has a groove 330, and the vibration detection device 400 is fixed in the groove 330 by a fastener. In this embodiment, the fastener is a screw. The two ends of the first clamping block 310 are respectively provided with a first protrusion 311 and a second protrusion 313. A first locking tooth 312 is provided on one side of the first protrusion 311, and a second locking tooth is provided on one side of the second protrusion 313. 314. The two ends of the second clamping block 320 are respectively provided with a first step portion 321 and a second step portion 323. The first step portion 321 is provided with a first slot portion 322, and the second step portion 323 is provided with a second slot portion 324. The first protrusion portion 311 is installed in the first step portion 321, the first tooth portion 312 is engaged with the first slot portion 322, the second protrusion portion 313 is installed in the second step portion 323, and the second tooth portion 314 is engaged with the second slot portion 324. The first clamping block 310 and the second clamping block 320 are both made of PVC material.
[0028] The working principle of this embodiment is as follows: By compressing the first clamping block 310, the first locking tooth 312 is engaged in the first locking groove 322, and the second locking tooth 314 is engaged in the second locking groove 324. Subsequently, the first clamping block 310 springs back, and the first locking tooth 312 is engaged more tightly in the first locking groove 322, and the second locking tooth 314 is engaged more tightly in the second locking groove, resulting in a better fixing effect between the first clamping block 310 and the second clamping block 320.
[0029] The remaining working principles of this embodiment are the same as those of Embodiment 1.
[0030] Example 3 This embodiment is a third embodiment of a drainage pipe with a blockage warning function. This embodiment is similar to embodiment two, except that, as Figure 3 and Figure 4 As shown, two annular protrusions 120 are provided on the inner walls of the two ports of the pipe body 100. The annular protrusions 120 are used to press against the outer wall of the outer pipe fitting 500. The pipe body 100 has two glue injection ports 130. A glue injection port 130 is provided between the two annular protrusions 120 at the same port. The glue injection port 130 is connected to the inner wall of the pipe body 100. An inwardly inclined guide portion 140 is provided at the port of the pipe body 100.
[0031] The working principle of this embodiment is as follows: Previously, adhesive was applied to the inner wall of the pipe body 100 before the outer fitting 500 was installed. However, the rolled edge at the port of the outer fitting 500 would scrape away some of the adhesive, resulting in an unstable connection. In this solution, when the outer fitting 500 is installed at the port of the pipe body 100, the outer wall of the outer fitting 500, the two adjacent annular protrusions 120, and the inner wall of the pipe body 100 form a sealed glue injection cavity 600. After installation, the operator can inject adhesive from the outside of the fitting body into the glue injection cavity 600 through the glue injection port 130. The adhesive fills the entire glue injection cavity 600, which can improve the sealing and tightness of the connection. The guide part 140 provides guidance when the outer fitting 500 is inserted into the port of the fitting body, making it more convenient.
[0032] The remaining working principles of this embodiment are the same as those of Embodiment 2.
[0033] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.
[0034] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make various variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
