[0035] The utility model provides a sewage detection device. Figures 1 to 4 This is an embodiment of the sewage detection device provided by the utility model.

[0036] Please also read Figures 1 to 4 The sewage detection device includes a pipeline 1 and a plurality of driving components 2, the pipeline 1 is used to transport sewage, at least one detection hole is opened on the pipeline 1, a rotating component 3 is arranged on the outer peripheral side of the pipeline 1, and a plurality of detection devices 4 are movably arranged on the rotating component 3, the rotating component 3 is used to drive the plurality of detection devices 4 to rotate so that the plurality of detection devices 4 are aligned with the detection hole one by one, the plurality of driving components 2 are arranged on the outer peripheral side of the rotating component 3, and the plurality of driving components 2 are respectively arranged on the plurality of detection devices 4, the driving component 2 drives the detection devices 4 to move toward or away from the pipeline 1, so that the detection devices 4 aligned with the detection hole enter or leave the detection hole.

[0037] The detection device 4 is installed inside the pipeline 1 through the detection hole to detect the sewage flowing inside the pipeline 1, so as to determine whether the discharged sewage meets the standard. After the detection device 4 located in the pipeline 1 has been running for a period of time, the driving component 2 is started to drive the detection device 4 located in the pipeline 1 to detach from the pipeline 1. After the detection device 4 is completely detached from the pipeline 1, the rotating component 3 is started to drive all the detection devices 4 to rotate together, so that the detection device 4 that has entered the pipeline 1 and is aligned with the detection hole changes its position and is no longer aligned with the detection hole, and another detection device 4 that has not entered the pipeline 1 is aligned with the detection hole, and then the driving component 2 is started to drive the detection device 4 that is aligned with the detection hole at this time to enter the detection hole, so that it is installed in the pipeline 1 to start the detection work.

[0038] The replaced detection device 4 is suspended in the air outside the pipeline 1, so that the sewage attached to the outer shell of the detection device 4 gradually slides off and dries. At the same time, cloth strips and other debris attached to the detection device 4 may also slide off, but cloth strips and other debris may be attached to the detection device 4 due to absorbing too much water and are difficult to remove. At the same time, grease and other adhesions in the sewage may also be attached to the detection device 4 and are difficult to remove. Therefore, the staff needs to maintain and clean the detection device 4 every once in a while, clean the debris and stains attached to the outer shell of the detection device 4, and calibrate the detection device 4 to ensure its detection accuracy after entering the pipeline 1 later. At the same time, the maintenance personnel only need to maintain and clean the detection device 4 exposed on the outside of the pipeline 1, so that the maintenance personnel do not need to disassemble and assemble during cleaning, which greatly improves the work efficiency. At the same time, the detection device 4 exposed on the outside of the pipeline 1 is convenient to disassemble and assemble without any obstacles, which also greatly improves the work efficiency of the maintenance personnel.

[0039] Therefore, in the technical solution provided by the utility model, a plurality of detection devices 4 are movably arranged on the rotating component 3, the rotating component 3 is used to drive the plurality of detection devices 4 to rotate, a plurality of driving components 2 are arranged on the outer peripheral side of the rotating component 3, and a plurality of driving components 2 are respectively arranged on a plurality of detection devices 4, the driving component 2 drives the detection devices 4 to move toward or away from the pipeline 1, so that the detection device 4 aligned with the detection hole enters or leaves the detection hole, and a new detection device 4 is replaced by the cooperation of the rotating component 3 and the driving component 2 to enter the pipeline 1 to detect the sewage discharge condition.

[0040] Furthermore, the number of the detection holes is less than the number of the detection devices 4 to prevent all of the detection devices 4 from entering the pipeline 1 .

[0041] When the number of detection holes is greater than or equal to the number of detection devices 4, all detection devices 4 can enter the pipeline 1 at the same time driven by the driving component 2. Subsequently, the driving component 2 drives all detection devices 4 to leave the pipeline 1, and after changing their positions through the rotating component 3, the detection devices 4 aligned with the detection holes are still the detection devices 4 that have been used in the pipeline 1 for a period of time. Therefore, the number of detection holes needs to be less than the number of detection devices 4, so that all detection devices 4 cannot enter the detection holes at the same time, thereby avoiding that the detection devices 4 that enter the pipeline 1 each time are the detection devices 4 that have entered the pipeline 1 last time.

[0042] In order to ensure that each detection device 4 entering the pipeline 1 is the detection device 4 that has not entered the pipeline 1 for detection work last time, and that no detection holes have corresponding detection devices 4, the number of detection devices 4 is preferably an integer multiple of the number of detection holes, so that the detection devices 4 can be replaced regularly, so that the same number of detection devices 4 are replaced into the pipeline 1 each time the detection devices 4 are replaced.

[0043] The main function of the driving component 2 is to drive the detection device 4 to move toward the pipeline 1, so that the detection device 4 aligned with the detection hole can enter the pipeline 1 through the detection hole to perform sewage detection.

[0044] Specifically, in an embodiment of the utility model, the driving component 2 includes an auxiliary box 201 and an electric push rod 202, the auxiliary box 201 is arranged on the outer peripheral side of the rotating component 3, the auxiliary box 201 rotates together with the rotating component 3, and an installation cavity is formed on the auxiliary box 201, the electric push rod 202 is arranged in the installation cavity, the electric push rod 202 is driven and connected to a connecting plate 203, and the detection device 4 is arranged on the side of the connecting plate 203 facing the pipeline 1, and the electric push rod 202 drives the connecting plate 203 toward the detection hole to drive the detection device 4 to enter the detection hole.

[0045] When it is necessary to drive the detection device 4 into the pipeline 1 or out of the pipeline 1, the electric push rod 202 is started. The electric push rod 202 drives the connecting plate 203 to move toward the pipeline 1 or away from the pipeline 1 through the output shaft, thereby driving the detection device 4 into the pipeline 1 or out of the pipeline 1 through the connecting plate 203, thereby realizing the function of automatically installing the detection device 4 in the pipeline 1 and automatically disassembling it from the pipeline 1.

[0046] The auxiliary box 201 is provided on the outside of the electric push rod 202 to protect the electric push rod 202 and to restrict the connecting plate 203 so that the connecting plate 203 will not move to collide with the electric push rod 202 when approaching the electric push rod 202. However, the connecting plate 203 gradually approaches the electric push rod 202 until it collides with the auxiliary box 201. The collision between the connecting plate 203 and the auxiliary box 201 will cause additional damage, resulting in a reduction in the service life of the connecting plate 203 and the auxiliary box 201. Therefore, a rubber pad is provided on one of the sides where the auxiliary box 201 and the connecting plate 203 collide with each other to reduce damage caused by the collision.

[0047] The function of the electric push rod 202 is to drive the object connected to its output shaft to make linear motion. Therefore, the electric push rod 202 can be replaced by a structure or device such as a cylinder that can drive the detection device 4 to move linearly through a program or manually. The specific structure or device used to drive the detection device 4 is set according to the actual situation of the position of the pipeline 1.

[0048] Furthermore, a seal is provided on the outer circumference of the pipeline 1 , and the seal is located on the outer circumference of the detection hole, so as to seal the gap between the connecting plate 203 and the pipeline 1 when the connecting plate 203 is attached to the pipeline 1 .

[0049] After the connecting plate 203 drives the detection device 4 to pass through the detection hole and enter the interior of the detection device 4, the connecting plate 203 may fit together with the pipe 1. The connecting plate 203 and the pipe 1 cannot fit together completely, so there is a gap between the connecting plate 203 and the pipe 1. When sewage flows in the pipe 1, when the sewage flow is too large to fill the entire pipe 1, the sewage may leak out through the gap between the connecting plate 203 and the pipe 1, causing pollution to the outside of the pipe 1. Therefore, it is necessary to set a seal at the position where the pipe 1 and the connecting plate 203 fit together, so that the sewage cannot leak out through the gap. At the same time, the specific shape of the connecting plate 203 is set according to the detection device 4. Different detection devices 4 may need to set connecting plates 203 of different shapes to adapt to the detection device 4. Therefore, the seal is preferably set on the pipe 1, and set around the hole located at the detection hole facing the outside of the pipe 1, so that any detection device 4 can complete the sealing work after entering the detection hole.

[0050] In order to start only the drive assembly 2 corresponding to the detection device 4 aligned with the detection hole, a corresponding structure needs to be set so that only the drive assembly 2 corresponding to the detection device 4 aligned with the detection hole will be started, while the drive assemblies 2 corresponding to other detection devices 4 not aligned with the detection hole will not be started, thereby preventing the detection device 4 not aligned with the detection hole from approaching the pipeline 1 and colliding with the pipeline 1 under the drive of the drive assembly 2.

[0051] Specifically, in the technical solution of the present invention, a trigger component is provided on the driving component 2, so that when the trigger component is triggered, the driving component 2 corresponding to the detection device 4 aligned with the detection hole is started. The function of the trigger component is to trigger the trigger component after the detection device 4 changes its position and is aligned with the detection hole, so that the electric push rod 202 of the driving component 2 corresponding to the detection device 4 is started, driving the detection device 4 to move toward the pipeline 1, and enter the pipeline 1 through the detection hole to perform sewage detection, while the detection device 4 that is not aligned with the detection hole is inactive, so as to avoid collision with the remaining pipelines 1 and cause damage.

[0052] The structural composition of the trigger component is various. For example, the trigger component includes at least one infrared transmitter 5 and multiple infrared receivers 6. At least one infrared transmitter 5 is set on the pipeline 1, and the infrared transmitter 5 emits infrared rays toward the auxiliary box 201. The multiple infrared receivers 6 are respectively set on the multiple auxiliary boxes 201. The infrared receivers 6 are used to collect the infrared rays emitted by the infrared transmitter 5 to detect the position of the driving component 2 after rotation.

[0053] When the detection device 4 is aligned with the detection hole, the infrared receiver 6 on the auxiliary box 201 of the drive component 2 corresponding to the detection device 4 will receive the infrared rays emitted by the infrared transmitter 5. After receiving the infrared rays, the infrared receiver 6 will transmit a signal to the corresponding drive component 2 to start the electric push rod 202 of the drive component 2, so that the electric push rod 202 drives the connecting plate 203 to drive the corresponding detection device 4 to move toward the pipeline 1 until the detection device 4 completely enters the pipeline 1 to perform sewage detection.

[0054] Further, the number of the infrared emitters 5 is equal to the number of the detection holes, so that the infrared emitters 5 detect the position of the detection device 4 aligned with the detection holes.

[0055] The infrared transmitter 5 is used to transmit infrared rays toward the auxiliary box 201 corresponding to the detection device 4 aligned with the detection hole, so the number of infrared transmitters needs to be limited, that is, each detection hole needs to have a corresponding infrared transmitter 5, so the number of infrared transmitters 5 is equal to the number of detection holes, and the infrared receiver 6 is a receiving device arranged on the auxiliary box 201 for receiving infrared signals so that the driving component 2 is driven, so the number of infrared receivers 6 is equal to the number of detection devices 4, so that each detection device 4 has a corresponding trigger component, and only the trigger component corresponding to the detection device 4 aligned with the detection hole will be triggered to start the corresponding driving component 2, so that only the detection device 4 aligned with the detection hole will be active and enter the pipeline 1 through the detection hole to perform sewage detection.

[0056] The main function of the rotating assembly 3 is to drive the driving assembly 2 to rotate so that the detection device 4 on the driving assembly 2 rotates together, thereby changing the position of the detection device 4, and further aligning different detection devices 4 with the detection holes.

[0057] Specifically, in an embodiment of the utility model, the rotating assembly 3 includes a supporting seat 301 and a rotating seat 303, the supporting seat 301 is formed with a accommodating cavity, a motor 302 is arranged in the accommodating cavity, the rotating seat 303 is drivingly connected to the motor 302, and the rotating seat 303 is arranged between the opposite sides of the multiple auxiliary boxes 201, the rotating seat 303 rotates under the drive of the motor 302, so that the rotating seat 303 drives the multiple auxiliary boxes 201 to rotate.

[0058] After the detection device 4 is completely separated from the pipeline 1 by the drive component 2, the motor 302 is started. The motor 302 drives the rotating seat 303 to rotate through the output shaft. The rotating seat 303 drives all the drive components 2 to rotate, thereby driving the detection device 4 on the drive component 2 to rotate. The detection device 4 changes its position during the rotation process, so that the detection device 4 currently corresponding to the detection hole gradually moves away from the detection hole, and other adjacent detection devices 4 gradually approach the detection hole. When the rotating seat 303 rotates a certain angle driven by the motor 302, the adjacent detection device 4 is aligned with the detection hole, and the previous detection device 4 is not aligned with any detection hole. Then the drive component 2 drives the detection device 4 aligned with the new detection hole to move toward the pipeline 1, so that the detection device 4 enters the pipeline 1 through the detection hole, thereby replacing the detection device 4 to enter the pipeline 1 for sewage detection.

[0059] The function of the rotating component 3 is to change the position of the detection equipment 4 so that the used detection equipment 4 no longer enters the pipeline 1. The unused detection equipment 4 is driven by the driving component 2 to enter the pipeline 1 to perform sewage detection to ensure the accuracy of the detection result. Therefore, the structural composition of the rotating component 3 is various. The rotating component 3 formed by the support seat 301, the rotating seat 303 and the motor 302 is only one of them, and it can be replaced accordingly according to the actual situation of the pipeline 1.

[0060] Furthermore, a rolling groove is provided on one side of the support seat 301 opposite to the rotating seat 303 , and a plurality of balls are rollingly connected in the rolling groove, and the balls are used to assist the rotating seat 303 in rotating.

[0061] When there is a certain distance between the rotating seat 303 and the supporting seat 301, the motor 302 drives the rotating seat 303 to rotate, which may cause the rotating seat 303 to shake. The rotation and shaking will cause the driving component 2 around the rotating seat 303 to tilt, and then cause the detection device 4 to tilt. After the detection device 4 tilts, it may not be able to align with the detection hole, causing the driving component 2 to drive the detection device 4 to move toward the detection hole. It cannot enter the detection hole and collides with the pipe 1. When there is no distance between the rotating seat 303 and the supporting seat 301, the rotating seat 303 will continue to rub against the supporting seat 301 during rotation, and the friction formed during rotation will cause friction between the rotating seat 303 and the supporting seat 301. The friction force will hinder the smooth rotation of the rotating seat 303, and also accelerate the wear of the rotating seat 303 and the support seat 301. Therefore, a plurality of balls are arranged between the support seat 301 and the rotating seat 303 to support the stable rotation of the rotating seat 303. At the same time, there is a certain distance between the support seat 301 and the rotating seat 303. At the same time, the balls roll in the rolling grooves as the rotating seat 303 rotates, so that the rotating seat 303 can rotate more smoothly, thereby improving the smoothness of the operation of the equipment and reducing the wear of the rotating seat 303 during the rotation process, thereby making the equipment run more stably.

[0062] When the detection device 4 enters the pipeline 1 to detect sewage, debris such as cloth strips carried in the sewage may cover the detection device 4 as the sewage flows. These cloth strips and other debris contain pollutants themselves, and long-term attachment to the detection device 4 will affect the detection accuracy of the detection device 4. Therefore, it is necessary to intercept these debris to prevent them from covering the detection device 4.

[0063] Specifically, in an embodiment of the utility model, the sewage flow direction in the pipe 1 is set to a first side, and the direction opposite to the first side is set to a second side. A filter screen 7 is arranged in the pipe 1, and the filter screen 7 is arranged on the second side of the detection device 4. The filter screen 7 is used to block debris in the sewage to prevent the debris from adhering to the detection device 4.

[0064] The filter net 7 is provided to filter out the debris in the sewage, so that the debris will not flow to the detection device 4, so that the detection device 4 only detects the sewage, avoiding the problem that the cloth strips and other debris cover the detection device 4 and affect the detection accuracy of the detection device 4. At the same time, some relatively hard objects can be intercepted to avoid these hard objects from hitting the detection device 4 with the flow of sewage, causing the detection device 4 to be damaged.

[0065] The filter screen 7 is arranged at an angle, and in an embodiment of the utility model, the filter screen 7 is inclined toward the flow direction of sewage, and the end of the filter screen 7 away from the inner wall of the pipe 1 is inclined close to the detection device 4. A certain inclination angle allows the debris intercepted by the filter screen 7 to escape from the filter screen 7 and flow downward along the inclined direction under the impact of sewage, thereby avoiding excessive accumulation of debris on the filter screen 7 to form a blockage. The filter screen 7 can be arranged on the connecting plate 203 together with the detection device 4 so that the filter screen 7 can enter or escape from the pipe 1 together with the detection device 4, thereby facilitating the staff to clean or replace the filter screen 7.

[0066] At the same time, an interception plate can also be set at one end of the filter screen 7 away from the inner wall of the pipe 1. The interception plate is located on the side of the detection device 4 away from the connecting plate 203. The interception plate is used to block the debris floating along the inclination direction of the filter screen 7 from floating toward the detection device 4, and the interception plate extends along the sewage flow direction to avoid the interception plate affecting the flow of sewage.

[0067] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the concept of the utility model, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
