Description

Technical Field

[0001] The utility model relates to the technical field of sewage detection, in particular to a sewage detection device for a drainage pipe network. Background Art

[0002] Drainage network refers to the pipe system used to discharge wastewater and sewage in cities or buildings. These pipes are usually made of various materials, such as PVC, cast iron, steel, etc. The design and layout of the drainage network are aimed at effectively collecting and discharging sewage to ensure the sanitary environment and public health of the city or building. The drainage network usually includes sewers, rainwater drainage systems and sewage treatment facilities. Sewage detection devices are usually distributed on the drainage network to detect the water quality of sewage.

[0003] A Chinese patent with authorization announcement number CN218331528U discloses a sewage detection device for a drainage network, which performs normal sewage sampling and detection by turning a first three-way valve and a second three-way valve to connect an extraction pipe, a suction pump, and a diversion pipe. The detected sewage enters a collection box. When cleaning, the first three-way valve and the second three-way valve are turned to connect the sewage diversion pipe, the suction pump, and the sewage discharge pipe, and the sewage discharge pipe of the collection box is flushed toward the filter cover to avoid clogging of the filter cover and affecting the sampling effect. No manual cleaning is required, which is more convenient.

[0004] The existing technology and the sewage detection devices mentioned above usually use a filter to filter large particles of impurities in the water before sampling to avoid damage to the detection instrument during the sampling process. However, since the direction of sewage inflow is fixed, the contact area between it and the filter is fixed, so that during the sampling and detection process, the filter will usually be partially blocked. Utility Model Content

[0005] In view of the problems existing in the background technology, a sewage detection device for drainage pipe network is proposed. A water guide component is arranged in the sampling box through a moving mechanism. When the sewage is discharged through the water inlet pipe, it contacts the water guide platform and disperses along the outside of the water guide platform, expanding the filtering area of ​​the filter screen. At the same time, the moving mechanism drives the water guide platform to rise and fall back and forth, and the sewage will be more easily dispersed and descended, effectively avoiding the frequent local blockage of the filter screen caused by concentrated water inflow.

[0006] The utility model provides a drainage pipe network sewage detection device, comprising

[0007] A base, on which a sampling box and a detector are symmetrically arranged, a side of the sampling box is connected to a water inlet pipe, and a bottom is connected to a drainage pipe passing through the base;

[0008] A filter plate is disposed in the sampling box, and a water guide component for dispersing the sewage descending area is disposed on the filter plate; and

[0009] The moving mechanism is arranged in the sampling box and is used for driving the water guiding component to move vertically back and forth.

[0010] Preferably, a sampling tube is connected between the sampling box and the detector. The sampling tube is relatively located below the filter plate, and a micro sampling pump is arranged in the middle of the sampling tube.

[0011] Preferably, the water guide assembly includes a limiting column, a connecting frame and a water guide platform. Two groups of limiting columns are provided and are both installed on the inner wall of the sampling box. The connecting frame is slidably arranged on the two limiting columns, and one end of the connecting frame is connected to the water guide platform located in the middle of the sampling box.

[0012] Preferably, the cross-section of the water inlet pipe is arranged to be an L-shaped structure, and the water outlet of the vertical section thereof is arranged directly opposite to the water guide platform.

[0013] Preferably, the moving mechanism includes a driving motor, a turntable and a cam shaft. The driving motor is installed on the back of the sampling box, and its output end passes through the sampling box and is connected to the turntable. A cam shaft is provided at an eccentric position on the side of the turntable.

[0014] Preferably, the connecting frame is configured as a T-shaped structure, a strip groove for the convex shaft to pass through is opened on the horizontal section, and a water leakage channel is opened on the vertical section.

[0015] Preferably, the water guide platform is configured as a truncated cone-shaped structure, and a water guide slope is obliquely provided on its outer side wall.

[0016] Through the above technical scheme, that is, the sewage detection device disclosed by the utility model, a water guide component is arranged in the sampling box through a moving mechanism. When the sewage is discharged through the water inlet pipe, it contacts the water guide platform, so that it is dispersed along the outer side of the water guide platform, expanding the filtering area of ​​the filter screen. At the same time, the moving mechanism drives the water guide component to reciprocate and rise and fall. During the lifting process, the distance between the water guide platform and the water outlet of the water inlet pipe is shortened, that is, the force of the falling water flow is increased, and the sewage will be more easily dispersed and dropped, effectively avoiding the frequent occurrence of local blockage of the filter screen caused by concentrated water inlet, thereby improving its practicality.

[0017] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0024] Embodiment 1

[0025] like Figure 1-Figure 4 As shown, the drainage network sewage detection device proposed by the utility model includes a base 1, a filter plate 6, a water guiding component and a moving mechanism. The base 1 is symmetrically provided with a sampling box 2 and a detector 3. The side of the sampling box 2 is connected to a water inlet pipe 4, and the bottom is connected to a drainage pipe 5 passing through the base 1. The sampling box 2 is provided with a filter plate 6, and a water guiding component for dispersing the sewage falling area is provided above the filter plate 6. The sampling box 2 is also provided with a moving mechanism for driving the water guiding component to move vertically back and forth.

[0026] The ends of the water inlet pipe 4 and the drain pipe 5 are both provided with connecting flanges, and the water inlet pipe 4 is connected to an external pump pipe through the connecting flanges.

[0027] like Figure 3 As shown, a sampling tube 7 is connected between the sampling box 2 and the detector 3. The sampling tube 7 is relatively located below the filter plate 6, and a micro sampling pump 8 is provided in the middle thereof. The sampling pump can be used to draw water in the sampling box 2 into the detector 3 for detection.

[0028] like Figure 4 As shown, the water guide assembly includes a limiting column 9, a connecting frame 10 and a water guide platform 11. Two groups of limiting columns 9 are provided, both of which are installed on the inner wall of the sampling box 2. The connecting frame 10 is slidably set on the two limiting columns 9, and one end of the connecting frame is connected to the water guide platform 11 located in the middle of the sampling box 2.

[0029] like Figure 3 As shown, the cross-section of the water inlet pipe 4 is set to an L-shaped structure, and the water outlet of its vertical section is set directly opposite to the water guide platform 11. The water guide platform 11 is set to a truncated cone structure, and a water guide slope is obliquely provided on its outer wall, so that the sewage is discharged through the end of the water inlet pipe 4, and falls onto the water guide platform 11 during the descent process, and the sewage is dispersed to the surroundings along the water guide slope.

[0030] Embodiment 2

[0031] like Figure 1-Figure 4 As shown, the drainage pipe network sewage detection device proposed by the utility model, based on the above embodiment, this embodiment also records in detail the specific components of the moving mechanism and the specific matching method between the moving mechanism and the connecting frame 10.

[0032] like Figure 4 As shown, the moving mechanism includes a driving motor 12, a turntable 13 and a cam 14. The driving motor 12 is installed on the back of the sampling box 2, and its output end passes through the sampling box 2 and is connected to the turntable 13. The cam 14 is arranged at an eccentric position on the side of the turntable 13. The turntable 13 is driven to rotate by the motor. During the rotation of the turntable 13, the cam 14 is driven to make a circular motion.

[0033] like Figure 4 As shown, the connecting frame 10 is configured as a T-shaped structure, a strip groove 15 for the convex shaft 14 to pass through is opened on its horizontal section, and a water leakage channel 16 is opened on its vertical section.

[0034] In summary, when the utility model is in use, the water inlet pipe 4 is connected to the pump pipe of the drainage pipe 5 network through a flange, so that the sewage is discharged through the end of the water inlet pipe 4, and falls onto the water guide platform 11 during the descent process. The sewage spreads around along the water guide slope, is filtered by the filter plate 6, and is collected in the sampling box 2. Then the sampling pump draws the sewage that has been initially filtered in the sampling box 2 into the detector 3 for detection. In the process of water diversion, by starting the motor, the motor drives the cam 14 to make a circular motion through the turntable 13. During the movement, it applies a thrust to the horizontal section of the connecting frame 10. Under the action of the thrust, the connecting frame 10 drives the water guide platform 11 to reciprocate and rise and fall under the limit of the limit column 9. During the lifting process, the distance between the water guide platform 11 and the water outlet of the water inlet pipe 4 is shortened, that is, the force of the falling water flow is increased, and the sewage will be more easily dispersed and descended, effectively avoiding the frequent local blockage of the filter screen caused by concentrated water inlet, thereby improving its practicality.

[0035] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
