Description

Technical Field

[0001] The utility model relates to the technical field of sewage monitoring, in particular to a sewage discharge monitoring device. Background Art

[0002] The existing Chinese patent application number: 202320854861.0 discloses a sewage monitoring device, including a hemispherical shell, a closed hollow space provided in the shell, a through hole opened on the shell, the through hole extending from the plane center of the shell to the spherical center of the shell, the through hole including a mounting hole for mounting an ultrasonic sensor and a threading hole for passing a cable, and the ultrasonic sensor is connected to a control terminal via a cable.

[0003] When the above technology is used, the device has a certain buoyancy through the setting of the hemispherical shell, so that it can always float on the surface of the sewage. However, in actual use, impurities in the sewage are easy to adhere to the surface of the shell, causing the shell to gradually increase in weight until the buoyancy provided by the shell is less than the total weight of the device. At this time, the device can no longer maintain the phenomenon of always floating on the surface of the sewage, which affects the device's monitoring effect on the sewage. Therefore, in order to solve the above technical problems, we proposed a sewage monitoring device. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a sewage monitoring device.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A sewage discharge monitoring device includes a device body for monitoring sewage and a mounting tube, wherein the device body is located inside an external sewage pipe, and the mounting tube is installed outside the external sewage pipe. A connecting rod is provided for sliding inside the mounting tube, and a displacement sensor is provided at one end of the mounting tube close to the sewage pipe. The pull rope end of the displacement sensor is connected to the upper end of the connecting rod, and the lower end of the connecting rod extends to the outside of the mounting tube and enters into the external sewage pipe and is finally connected to the device body. A limiting groove is provided at the upper end of the connecting rod, and a matching guide protrusion is provided inside the mounting tube corresponding to the limiting groove, and a water level sensor is provided in the sewage pipe.

[0007] Preferably, the upper end of the installation tube is in an open state, and a sealing cover is installed at the opening of the upper end of the installation tube by screws.

[0008] Preferably, a guide rod is fixed to the lower surface of the sealing cover, and the lower end of the guide rod is inserted into the interior of the linkage rod.

[0009] Preferably, a pressure relief hole is provided on the rod body of the guide rod, and a matching reflux port is provided on one side of the upper end of the connecting rod corresponding to the pressure relief hole.

[0010] Preferably, a sealing ring is installed on the end surface of the lower end of the installation cylinder, and the inner wall of the sealing ring is in contact with the outer ring surface of the connecting rod.

[0011] Preferably, the inner annular surface of the mounting cylinder and the outer annular surface of the connecting rod are both smooth surfaces, and the outer annular surface of the connecting rod is provided with an anti-rust layer.

[0012] Preferably, a protective cover is installed on the outside of the installation cylinder, and one side of the protective cover is arranged on the outside of the displacement sensor.

[0013] The utility model proposes a sewage discharge monitoring device, which has the following beneficial effects:

[0014] 1: In the present invention, by installing a cylinder, a connecting rod, a displacement sensor and a water level sensor, when the sewage level remains unchanged, the value measured by the displacement sensor becomes smaller, indicating that the main body of the surface device is sinking into the sewage. When the amount of sewage discharged from the outside remains unchanged, and the water level sensor measures that the sewage level in the sewage pipe rises, it indicates that the drainage end of the sewage pipe is blocked, making it impossible for the sewage in the sewage pipe to be discharged normally, so that the external on-duty personnel can clearly and timely obtain the blockage situation in the sewage pipe and whether the main body of the device is floating normally on the sewage surface. Therefore, compared with the traditional solution, this solution can not only monitor the suspension height of the main body of the device to prevent it from being immersed in sewage and damaged, but also can feedback the blockage situation in the sewage pipe from the side, so that the blockage situation in the sewage pipe can be more fully and accurately monitored when this solution is used.

[0015] 2: The provision of the sealing cover in the present invention facilitates maintenance of components inside the mounting tube by personnel; the provision of the pressure relief hole allows the air between the connecting rod and the guide rod to enter the mounting tube through the pressure relief hole, or the air inside the mounting tube to enter the connecting rod when the connecting rod moves up and down, so as to avoid high pressure in the space between the connecting rod and the guide rod and affect the measurement accuracy of the displacement sensor. At the same time, the air at the upper and lower ends of the mounting tube can flow up and down through the return port, thereby avoiding high pressure on the upper and lower ends of the mounting tube when the connecting rod moves up and down, that is, further avoiding the phenomenon that the air inside the mounting tube interferes with the measurement of the displacement sensor.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Example 1

[0024] Reference Figure 1-5 A sewage monitoring device includes a device body 1 for monitoring sewage and a mounting tube 2. The device body 1 is located inside an external sewage pipe, and the mounting tube 2 is installed outside the external sewage pipe. A connecting rod 3 is provided for sliding inside the mounting tube 2. A displacement sensor 4 is provided at one end of the mounting tube 2 close to the sewage pipe. The pull rope end of the displacement sensor 4 is connected to the upper end of the connecting rod 3. The lower end of the connecting rod 3 extends to the outside of the mounting tube 2 and enters into the external sewage pipe and is finally connected to the device body 1. A limiting groove 5 is provided at the upper end of the connecting rod 3, and a matching guide protrusion 6 is provided inside the mounting tube 2 corresponding to the limiting groove 5. A water level sensor 13 is provided in the sewage pipe.

[0025] Example 2

[0026] Reference Figure 1-5 , while other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is:

[0027] The upper end of the mounting tube 2 is in an open state, and a sealing cover 7 is installed at the opening of the upper end of the mounting tube 2 by screws. The setting of the sealing cover 7 allows the upper end of the mounting tube 2 to be opened, and then when the connecting rod 3 or the displacement sensor 4 is damaged, the personnel can disassemble the connecting rod 3 from the upper end of the mounting tube 2, which is convenient for the personnel to repair the internal parts of the mounting tube 2; a guide rod 8 is fixed to the lower surface of the sealing cover 7, and the lower end of the guide rod 8 is inserted into the interior of the connecting rod 3. The setting of the guide rod 8 adds an additional guide limit mechanism between the connecting rod 3 and the mounting tube 2, so that the connecting rod 3 moves up and down more smoothly and stably; a pressure relief hole 10 is provided on the rod body of the guide rod 8, and the upper end of the connecting rod 3 is opened. A corresponding return flow port 11 is provided on one side corresponding to the pressure relief hole 10. The setting of the pressure relief hole 10 allows the air between the connecting rod 3 and the guide rod 8 to enter the interior of the mounting tube 2 through the pressure relief hole 10, or the air inside the mounting tube 2 to enter the connecting rod 3, so as to avoid high pressure in the space between the connecting rod 3 and the guide rod 8 and affect the measurement accuracy of the displacement sensor 4; the air at the upper and lower ends of the mounting tube 2 can flow up and down through the return flow port 11, thereby avoiding high pressure on the upper and lower ends of the mounting tube 2 when the connecting rod 3 moves up and down, that is, further avoiding the phenomenon that the air inside the mounting tube 2 interferes with the measurement of the displacement sensor 4.

[0028] The end face of the lower end of the mounting cylinder 2 is provided with a sealing ring 12, and the inner wall of the sealing ring 12 fits with the outer ring surface of the connecting rod 3. The setting of the sealing ring 12 blocks the sewage on the outer ring surface of the connecting rod 3 when the connecting rod 3 moves upward, thereby reducing the phenomenon that the sewage in the sewage pipe enters the interior of the mounting cylinder 2, that is, ensuring the smooth movement between the connecting rod 3 and the mounting cylinder 2; the inner ring surface of the mounting cylinder 2 and the outer ring surface of the connecting rod 3 are both smooth surfaces, and the outer ring surface of the connecting rod 3 is provided with an anti-rust layer. A protective cover 9 is installed on the outside of the mounting cylinder 2, and one side of the protective cover 9 is provided on the outside of the displacement sensor 4. The setting of the protective cover 9 can protect the displacement sensor 4 to prevent it from being accidentally damaged by collision.

[0029] Principle of use and advantages: During use, the utility model monitors the sewage in the external sewage pipe through the device body 1, so that personnel can clean the congestion of the sewage pipe in time. In the traditional scheme, as the device body 1 is used for a long time, its surface gradually adheres to impurities in the sewage, which increases the overall weight of the device body 1, that is, the device body 1 gradually moves downward until the device body 1 is finally submerged in the sewage, causing damage to it. However, in this scheme, since the mounting cylinder 2 is connected to the device body 1 through the connecting rod 3, that is, when the device body 1 gradually sinks into the sewage, the device body 1 drives the connecting rod 3 to move synchronously, and when the connecting rod 3 descends, it drives the pull rope end of the displacement sensor 4 to move downward, that is, the data measured by the displacement sensor 4 becomes smaller. At this time, personnel can judge the depth of the device body 1 immersed in the sewage at this time according to the data of the displacement sensor 4, so as to clean the impurities adhering to the surface of the device body 1 in time and make the device body 1 float on the sewage surface again.

[0030] In summary, during the use of this solution, by installing the cylinder 2, the connecting rod 3, the displacement sensor 4 and the water level sensor 13, when the sewage water level remains unchanged, the value measured by the displacement sensor 4 becomes smaller, which means that the surface device body 1 is sinking into the sewage. When the amount of sewage discharged from the outside remains unchanged, and the water level sensor 13 measures that the sewage water level in the sewage pipe has risen, it indicates that the drainage end of the sewage pipe is blocked, making it impossible for the sewage in the sewage pipe to be discharged normally, so that the external on-duty personnel can obtain the blockage situation in the sewage pipe clearly and in a timely manner, and whether the device body 1 is floating normally on the sewage surface. Therefore, compared with the traditional solution, this solution can not only monitor the suspension height of the device body 1 when in use to prevent it from being immersed in sewage and damaged, but also can feedback the blockage situation in the sewage pipe from the side, so that the blockage situation in the sewage pipe can be more fully and accurately monitored when this solution is used.

[0031] It should be further explained that the setting of the sealing cover 7 allows the upper end of the mounting tube 2 to be opened, and then when the connecting rod 3 or the displacement sensor 4 is damaged, personnel can disassemble the connecting rod 3 from the upper end of the mounting tube 2, which makes it convenient for personnel to repair the internal components of the mounting tube 2; the setting of the pressure relief hole 10 allows the air between the connecting rod 3 and the guide rod 8 to enter the mounting tube 2 through the pressure relief hole 10 when the connecting rod 3 moves up and down, or the air inside the mounting tube 2 enters the connecting rod 3, so as to avoid the high pressure in the space between the connecting rod 3 and the guide rod 8 and affect the measurement accuracy of the displacement sensor 4. At the same time, the air at the upper and lower ends of the mounting tube 2 can flow up and down through the return port 11, so as to avoid the high pressure at the upper and lower ends of the mounting tube 2 when the connecting rod 3 moves up and down, that is, further avoid the phenomenon that the air inside the mounting tube 2 interferes with the measurement of the displacement sensor 4; the setting of the protective cover 9 can protect the displacement sensor 4 to prevent it from being accidentally damaged by collision.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
