Description

Technical Field

[0001] The utility model relates to the technical field of pipeline network detection, in particular to a rainwater pipeline network discharge detection device. Background Technique

[0002] The main purpose of the rainwater pipeline network is to effectively collect and discharge rainwater, prevent ground rainstorm waterlogging in urban residential areas and industrial enterprises, and protect normal life and production from being affected. According to the prior art, such as a city sewage discharge pipeline network detection device described in the Chinese patent document CN219530580U, the disclosed technical solution drives the paddle to swing through the sewage flow, so that the deflector at one end of the rotating shaft rotates. When the deflector rotates, it will pass over the top of the sensor. The sensor is electrically connected to the controller. When the sensor receives the signal that the sensor is scratched, it will transmit the signal to the ground control center. When the pipeline is blocked, the signal is interrupted, and it can be known which pipeline is blocked, and the pipeline can be dredged in time.

[0003] According to the disclosed technical solution, the detection devices applied to the rainwater pipeline network discharge in the prior art mainly achieve the detection purpose by detecting the water flow state. However, when the water flow velocity is low, or the rotating structure is blocked due to long-term operation, it will cause the rotating structure not to rotate under low flow velocity and low flow rate conditions, resulting in detection errors. On the other hand, conventional detection devices cannot detect the silt depth at the bottom of the pipeline network to judge whether it is necessary to carry out early dredging, and can only detect whether the phenomenon of flow interruption occurs. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a rainwater pipeline network discharge detection device to solve the problems raised in the above background technique. The utility model can judge whether the flow interruption state is caused by blockage, and can judge the current silt depth, and has a longer service life and accuracy.

[0005] In order to achieve the above purpose, the utility model is realized by the following technical scheme: a rainwater pipeline network discharge detection device, including a detection device body, the detection device body includes a detection sleeve, a detection component and a guiding mechanism. The two ends of the detection sleeve are combined and connected with the rainwater pipeline network through flange plates. The guiding mechanism is integrally formed on the top of the detection sleeve. The detection component is installed inside the detection sleeve. A floating plate and a settling plate are installed at the bottom of the detection component. The top of the detection component is embedded inside the guiding mechanism.

[0006] Further, the guiding mechanism includes a convex column, a first guiding channel and a second guiding channel. The first guiding channel and the second guiding channel are opened inside the convex column. A ranging module is installed at the top end of the inner wall of the first guiding channel.

[0007] Furthermore, the ranging module adopts a laser ranging probe device. The number of the second guiding channels is two, and the first guiding channel is opened at the middle position between the two second guiding channels.

[0008] Furthermore, the detection component includes a floating plate and a settling plate. A second connecting rod is integrally formed at the top of the settling plate, and a first connecting rod is integrally formed at the top of the floating plate.

[0009] Furthermore, a first lifting column is integrally formed at the top of the first connecting rod. A reflecting sheet is attached to the surface of the first lifting column. A second lifting column is integrally formed at the top of the second connecting rod. The second lifting column is integrally embedded into the interior of the second guiding channel, and the first lifting column is embedded into the interior of the first guiding channel.

[0010] Furthermore, fixed convex plates are integrally formed at both ends of the settling plate. The second connecting rod is arranged on the surface of the fixed convex plate. A plugging column and a limiting rod are welded at the middle position of the settling plate. An electrode sheet is attached to the top of the plugging column, and a limiting convex disk is welded at the top of the limiting rod.

[0011] Furthermore, movable convex plates are integrally formed at both ends of the floating plate. A lifting hole is opened at the middle of the movable convex plate. A guiding hole is opened on the surface of the floating plate, and a plugging groove is opened at the bottom of the floating plate.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please refer to Figures 1 to 4 , the present utility model provides the following technical solutions: A rainwater pipe network discharge detection device includes a detection device body. The detection device body includes a detection sleeve 1, a detection component 2 and a guiding mechanism 3. The two ends of the detection sleeve 1 are combined and connected with the rainwater pipe network through flange plates. The guiding mechanism 3 is integrally formed on the top of the detection sleeve 1. The detection component 2 is installed inside the detection sleeve 1. A floating plate 8 and a settling plate 9 are installed at the bottom of the detection component 2. The top of the detection component 2 is embedded inside the guiding mechanism 3. This rainwater pipe network discharge detection device is used to detect whether there is rainwater flow inside the rainwater pipe network, and after detecting a flow interruption, it can also continue to detect the depth of the silt at the bottom of the rainwater pipe network, so as to comprehensively judge whether the rainwater pipe network needs to be dredged.

[0024] When the utility model is in use, it can be directly connected and installed with the pipeline part of the rainwater pipe network body by passing bolts through the flange structures at both ends of the detection sleeve 1, and then it can be used. During the subsequent detection and use process, when the rainwater inside the rainwater pipe network flows and discharges normally, the detection component 2 at the bottom will be triggered by the buoyancy generated by the liquid. After the detection component 2 is floated, the floating state information at this time can be obtained by means of the electrical signal disconnected at the position of the electrode plate 21, and then it can be judged that there is liquid flow. When the liquid flow stops, the information can be quickly obtained through the connection of the electrode plate 21. At the same time, the height of the bottom detection component 2 can also be judged by the ranging module 7 at the top, and then the liquid level of the rainwater and the depth of the silt at the bottom during subsequent flow interruption can be judged, so as to obtain more abundant and detailed rainwater flow information inside the rainwater pipe network under the use state.

[0025] In this embodiment, the guiding mechanism 3 includes a convex column 4, a first guiding channel 5 and a second guiding channel 6. The first guiding channel 5 and the second guiding channel 6 are opened inside the convex column 4. The top end of the inner wall of the first guiding channel 5 is provided with a ranging module 7. The ranging module 7 adopts a laser ranging probe device. The number of the second guiding channels 6 is two, and the first guiding channel 5 is opened at the middle position between the two second guiding channels 6. When the state of flow interruption is detected, the depth of the current bottom detection component 2 can be judged by the ranging module 7 at the top, and then the depth of the bottom silt can be obtained, thus providing an additional reference basis for whether dredging is needed and further expanding the performance monitoring range of the drainage inside the pipe network.

[0026] Specifically, the first lifting column 11 is guided by the first guiding channel 5, and the second lifting column 14 is guided by the second guiding channel 6. The ranging module 7 can detect the height of the reflecting sheet 12 at the top of the first lifting column 11, and then judge the height of the bottom floating plate 8. Therefore, under the state of rainwater flow, the height of the floating plate 8 is the liquid level height, and under the state of flow interruption, the height of the floating plate 8 is the depth of the bottom silt.

[0027] In this embodiment, the detection component 2 includes a floating plate 8 and a settling plate 9. A second connecting rod 13 is integrally formed at the top of the settling plate 9, and a first connecting rod 10 is integrally formed at the top of the floating plate 8. A first lifting column 11 is integrally formed at the top of the first connecting rod 10, and a reflective sheet 12 is attached to the surface of the first lifting column 11. A second lifting column 14 is integrally formed at the top of the second connecting rod 13, and the second lifting column 14 is integrally embedded inside the second guiding channel 6, and the first lifting column 11 is embedded inside the first guiding channel 5. Specifically, by connecting the first connecting rod 10 to the first lifting column 11 at the top, the height of the reflective sheet 12 at the top can be synchronously controlled by the floating plate 8 at the bottom to change. Then, the real-time height information of the floating plate 8 can be obtained by means of the ranging module 7 at the top. The ranging module 7 is an existing mature technology and does not fall within the protection scope of the present utility model. Therefore, its specific structure and principle will not be elaborated herein. In this embodiment, a laser ranging probe is used as the ranging module 7 to detect the height of the reflective sheet 12.

[0028] In this embodiment, fixed convex plates 19 are integrally formed at both ends of the settling plate 9, and the second connecting rod 13 is arranged on the surface of the fixed convex plates 19. A plugging column 20 and a limiting rod 22 are welded at the middle position of the settling plate 9. An electrode sheet 21 is attached to the top of the plugging column 20, and a limiting convex disc 23 is welded at the top of the limiting rod 22. Movable convex plates 15 are integrally formed at both ends of the floating plate 8, a lifting hole 16 is formed in the middle of the movable convex plates 15, a guiding hole 18 is formed on the surface of the floating plate 8, and a plugging groove 17 is formed at the bottom of the floating plate 8. The top end of the plugging column 20 is embedded inside the plugging groove 17, the limiting rod 22 passes through the inside of the guiding hole 18, and the second connecting rod 13 passes through the inside of the lifting hole 16. The water flow rate is detected by the detection component 2 at the bottom, and it can float along with the flow of rainwater, and then the current water level height is judged, so as to judge whether a blockage has occurred, and the monitoring sensitivity is high.

[0029] Whether a flow interruption occurs is judged by whether the electrode sheet 21 at the bottom is connected. Part of the electrode sheet 21 is shielded and covered by the floating plate 8 and the settling plate 9, and can always be hidden inside a closed cavity, so as to prevent external impurities from adhering to the surface of the electrode sheet 21, enabling it to have a longer service life and extending the period of manual maintenance and cleaning.

[0030] Specifically, in the floating state, the floating plate 8 floats on the liquid surface. Due to the connection of the limiting rod 22 and the limiting convex disk 23, the settling plate 9 will be pulled upward by the floating plate 8 at the top synchronously. At this time, the settling plate 9 is below the liquid surface, but the insertion column 20 is always embedded inside the insertion slot 17. However, due to the gap between the floating plate 8 and the settling plate 9, the electrode plate 21 cannot contact the inner wall of the insertion slot 17, and the circuit cannot be connected, so no electrical signal can be generated, indicating that the liquid is flowing normally at this time. Until the flow is interrupted, the floating plate 8 no longer floats up, the floating plate 8 and the settling plate 9 come into contact with each other, the electrode plate 21 fits against the inner wall of the insertion slot 17, generates an electrical signal, and sends the information of the interrupted flow. At this time, the height of the floating plate 8 can be detected by the ranging module 7 to obtain the sludge depth data.

For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms.

[0032] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
