Description

Technical Field

[0001] The present invention belongs to the technical field of water quality detection, and particularly relates to a sewage water quality detection device and method for municipal drainage pipelines. Background Technique

[0002] With the acceleration of the urbanization process, the drainage pipe network undertakes the important task of discharging sewage and maintaining the normal operation of the city, and the sewage water quality detection device provides data support for pipe network maintenance, pollution source tracing and intelligent water service management by real-time monitoring of water quality parameters.

[0003] In the sewage water quality detection work of municipal drainage pipelines, it is necessary to use special containers to separately extract sewage samples from different positions of the drainage pipeline and multiple drainage pipelines according to specific water quality detection requirements to achieve sampling at different points. After sampling, multiple containers filled with sewage samples need to be placed on the detection equipment in an orderly manner for subsequent detection operations. Currently, the common practice is to use a turntable to place these containers. However, when the number of containers to be detected is large, a problem will occur: the sewage-containing containers in the later stage of the detection process will have a large waiting time span, and during the waiting process, various substances in the sewage will gradually precipitate due to gravity, resulting in the sewage being stratified; when using the detection head to detect this stratified sewage, due to the uneven distribution of sewage components and the differences in water quality of different layers of sewage, the final detection result will deviate from the actual water quality situation, affecting the accuracy of the detection result. Summary of the Invention

[0004] The purpose of the present invention is to provide a sewage water quality detection device and method for municipal drainage pipelines to solve the problem that in the detection of multiple containers after sampling at different points for municipal drainage sewage detection, the sewage will precipitate and stratify due to the large detection time span, resulting in inaccurate detection as mentioned in the above background technique.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A sewage water quality detection device for municipal drainage pipelines, including a box body; a box door that is rotatably connected to the front surface and can be opened and closed; an installation plate is also installed inside the box body; a detection mechanism is arranged inside the box body, and the detection mechanism includes:

[0006] A detection component, which consists of a lifting component fixed on the installation plate and a detection part that is liftably connected to the lifting component; a cylinder is arranged inside the lifting component, and the lifting seat is installed on the output end of the cylinder. The cylinder is not shown in the figure because the improvement here is not within the scope of the present invention and the structural principle is known, so it will not be further described here;

[0007] An installation component, which is located below the detection part;

[0008] The toggle assembly is placed below the mounting assembly. When the mounting assembly rotates, the toggle assembly partially protrudes into the mounting assembly or is hidden in the lower surface of the mounting assembly. When the mounting assembly rotates, the toggle assembly will lift the container by protruding until it is hidden. After being lifted, the container will change from its initial vertical shape to an inclined shape and swing under gravity, thereby preventing the sewage inside from stratifying due to long-term standing.

[0009] The clamping assembly is located below the detection assembly and is arranged opposite to the mounting assembly. The clamping assembly performs an oblique clamping or oblique separation action toward the inner side of the mounting assembly under the lifting movement of the detection assembly. When the container is about to be inspected, in order to prevent the container from still shaking, the container is held tightly by the clamping assembly to achieve position limiting.

[0010] As a preferred technical solution in the present invention, the mounting assembly includes a supporting plate and a turntable installed above the supporting plate, wherein the bottom end of the supporting plate is provided with an integrated driving gear disc, and a driving motor, a belt and other structures are also provided inside the box body, the belt is driven by the driving motor to rotate, and the belt drives the driving gear disc, and the rotation of the supporting plate and the turntable is realized by the driving gear disc, so as to detect all containers placed on the turntable. Since this structure is a prior art and has nothing to do with the improvement of the present invention, it will not be further described here; a plurality of circular holes are opened on the surface of the turntable, a ring is placed in each circular hole, and a container is inserted in the ring, wherein the container is used to place the sewage to be tested, in order to prevent the sewage from overflowing during shaking, the sewage placed in the container shall not exceed two-thirds of its own height, and at the same time, this liquid level height is also suitable for the detection needs of conventional laboratories, and the bottom area of the container is a hemispherical arc. This shape setting can not only ensure that at least one area is supported by the supporting plate, but also can be swung during the later dialing, because the support plate and the container are in a stable state. The contact area is small, and the friction force that needs to be overcome during the swing is also small, so it will not affect the normal swing. At the same time, every time the support plate rotates, all the containers will be moved, ensuring that the container on the farthest side avoids stratification through multiple shifts. A drum spring is also provided on the inner side of the collar. The two ends of the drum spring are overlapped on the upper and lower end surfaces of the collar by bending and limiting, and the middle part of the drum spring bulges toward the middle of the collar. The middle part of the drum spring is against the surface of the container, and the installation of the container is achieved by the elastic pressing of the drum spring. It should be noted here that the rebound force of the drum spring should be It can ensure that the container filled with sewage will not be displaced or fall when it is swung; end posts are symmetrically arranged on both sides of the collar, and holes for the end posts to be inserted are opened on the inner wall of the circular hole on the turntable. When the container is moved, the top of the container will drive the collar to swing synchronously. At this time, the collar will swing around the axis of the end posts. The end posts can also ensure that the container can only swing in a single direction. The end posts can be first inserted into the holes on the inner wall of the circular hole, and then the collar equipped with the drum spring and the end posts are installed by hot melting or other methods to ensure a stable connection;The surface of the support plate is provided with arc grooves at equal angles, the number of which is equal to the number of the circular holes and containers, and the vertical projection of the arc grooves passes through the center of the circular holes on the support plate. The toggle assembly partially protrudes from the arc groove to the outside of the top of the support plate. When the support plate and the turntable rotate synchronously, the protruding portion of the toggle assembly contacts the bottom of the container, thereby blocking the bottom of the container. At the same time, the top of the container is not fixedly installed, so the bottom of the container changes from its initial vertical shape to an inclined shape after being blocked. When the support plate and the turntable continue to rotate, the toggle assembly is hidden under the support plate and does not block the swinging container. At this time, the top of the container also rotates synchronously, thereby shaking the sewage inside the container to avoid stratification. At the same time, when the support plate and the turntable rotate, the container itself is also subjected to centrifugal force to cause swinging, thereby further enhancing the shaking effect.

[0011] As a preferred technical solution in the present invention, the toggle assembly includes a bottom ring placed under the supporting plate, the bottom of the bottom ring is fixed with a pillar, and the pillar is placed on the inner bottom end surface of the box body to ensure the installation support of the bottom ring, and at the same time it will not rotate due to the support plate; the top of the bottom ring is also provided with a tightening piece at an equal angle, and each tightening piece corresponds to an arc groove; the tightening piece is composed of a tightening part that passes through the arc groove, and a connecting part that is integrally formed at both ends of the tightening part. In the initial state, the tightening part passes through the arc groove and is in a state where the container is about to rotate. The direction of movement, when the supporting plate and the turntable rotate synchronously, the container contacts the tightening part in the direction of rotation and is blocked by the tightening part, and a spring is provided between the end of the tightening part and the bottom ring; the bottom end surface of the supporting plate is also provided with an annular groove, which connects all the arc grooves; after the supporting plate and the turntable continue to rotate, the tightening part will move into the annular groove, and the tightening part will squeeze the spring at this time, so that the height of the tightening part will drop, thereby moving into the annular groove, and the surface of the supporting plate no longer has any structure that restricts the swing of the container. At this time, the container swings automatically under the action of gravity.

[0012] As a preferred technical solution in the present invention, a placement groove is provided at the downward position of the middle part of the mounting plate, the clamping assembly is placed in the placement groove, and a movable groove is provided at the top of the placement groove. The detection part includes a lifting seat installed in a lifting manner on the lifting assembly, and a detection head is installed on the lifting seat. A connecting plate is fixedly provided at the bottom of the lifting seat, and the connecting plate passes through the movable groove and is connected to the clamping assembly. The clamping assembly is driven to perform clamping movement through the connecting plate. Since the connecting plate is connected to the lifting seat, the container can be clamped and limited in position by the connecting plate before detection to avoid the situation where the container continues to shake and affects the normal detection.

[0013] As a preferred technical solution in the present invention, the clamping assembly includes a symmetrically arranged clamping member, which is composed of a clamping arc plate, a horizontal plate, and an inclined plate with a rack, wherein the clamping arc plate is clamped to the outside of the container by displacement to limit the container; the horizontal plate connects the clamping arc plate and the inclined plate with the rack, and the three are arranged in one piece; the inclined plate with the rack fits the inner wall of the mounting plate, that is, the side wall of the placement groove is also inclined, thereby limiting the inclined plate with the rack, and at the same time ensuring that the inclined plate with the rack is inclined The cam is mounted on a rear surface of the mounting plate, and two transmission members are symmetrically fixed to the top surface of the inner plate. The two transmission members are respectively engaged with the inclined plates with racks at corresponding positions. A driving member is also provided between the two transmission members. A spur rack is also passed through the inner plate, and the inner side surface of the spur rack is engaged with the driving member, and the top of the spur rack is fixed to the connecting plate. The lifting and lowering of the connecting plate drives the lifting and lowering of the spur rack, and the positive and negative meshing drive of the driving member is realized by the lifting and lowering of the spur rack.

[0014] As a preferred technical solution in the present invention, the driving member includes a transmission column and a bevel gear fixed at both ends of the transmission column. A transmission tooth portion is also formed in the middle of the transmission column, and the transmission tooth portion is meshed and connected with the spur rack. When the spur rack follows the connecting plate to move downward, the spur rack will drive the transmission tooth portion to rotate, and then the bevel gear drives the transmission member to rotate, and the transmission member drives the inclined plate with the rack to move toward the direction of the container. Due to the inclined setting of the inclined plate with the rack, when the container is shaking, the clamping arc plate can clamp and limit the container obliquely from both sides.

[0015] As a preferred technical solution in the present invention, the transmission member includes a driving gear with a shaft, the driving gear rotates around its own axis, and the shaft of the driving gear is fixed on the inner plate, and a bevel gear 2 is fixed on the driving gear, the bevel gear 2 is engaged with the bevel gear 1, and the driving gear is engaged with the inner wall of the inclined plate with the rack. When the bevel gear 1 drives the bevel gear 2 to rotate, the bevel gear 2 synchronously drives the driving gear, and finally the driving gear drives the inner wall of the inclined plate with the rack to transmit, thereby realizing the extension and retraction of the entire clamping member, wherein the driving gear and the bevel gear 1 do not contact.

[0016] As a preferred technical solution in the present invention, the surface of the transmission column is also provided with two support seats, which are symmetrically arranged at both ends of the transmission tooth portion. The transmission column and the support seats are rotatably connected, and the installation of the transmission column is achieved through the support seats. The bottom of the support seat is installed on the inner plate.

[0017] As a preferred technical solution in the present invention, a rack is formed in the middle and lower region of the straight rack, while the upper region of the straight rack is planar, and there is no contact between the upper region of the straight rack and the transmission gear portion. When the lifting seat descends, it will drive the detection head and the connecting plate to descend synchronously. At this time, the connecting plate will drive the driving member to transmit through the straight rack, so as to realize the extension of the clamping member. When the clamping arc plate completes the clamping and limiting of the container, the detection head does not reach the specified detection position. At this time, the lifting seat continues to descend. At this time, the upper region of the straight rack will descend to the transmission gear portion and will not drive the transmission gear portion to rotate. At this time, the clamping arc plate will not further press the container tightly to cause movement interference, and the detection head can continue to descend normally to the specified position.

[0018] The present invention also discloses a method for detecting the sewage water quality of a municipal drainage pipeline, including a water quality detection device, and specifically includes the following steps:

[0019] Step 1: Insert the container into the collar. At the same time, the container is tightly clamped and limited by the drum spring. At this time, apply a pressure greater than the clamping force of the drum spring until the bottom end of the container touches the supporting plate. After all the containers are installed, perform water quality detection;

[0020] Step 2: The lifting seat descends under the action of the lifting component, and the detection head is sent into the container to detect the water quality. At the same time, during the descent of the lifting seat, the lifting seat drives the connecting plate, the connecting plate drives the straight rack, and the transmission gear portion is driven through the straight rack. At this time, the transmission gear portion drives the entire transmission column to move, and then the bevel gear 1 drives the bevel gear 2. At this time, the driving gear follows the bevel gear 2 to move, and drives the inclined plate with a rack through the driving gear. At this time, the inclined plate with a rack extends obliquely along the inner wall of the placement groove and hugs and clamps the container from both sides of the container below the detection head through the clamping arc plate. Subsequently, the lifting seat continues to move downward. At this time, the part of the upper inner wall of the straight rack without a rack no longer drives the transmission gear portion to rotate until the detection head descends to the specified position to detect the water quality;

[0021] Step 3: When the detection is completed, the lifting seat is lifted under the drive of the lifting component. At this time, the detection head is lifted and separated from the container, and the connecting plate synchronously drives the straight rack. The straight rack reversely drives the transmission gear portion to realize the inclined retraction of the clamping member in a direction away from both sides of the container. Then, the supporting plate and the turntable are rotated. At this time, the bottom of the subsequent container to be detected will be blocked by the connecting portion, and the top of the container will drive the collar to tilt synchronously due to the inclination change of the bottom, so that the container itself will tilt until the tilt angle of the container becomes larger and exceeds the clamping portion. After the supporting plate and the turntable continue to rotate, the clamping portion will move into the annular groove, and the clamping portion will squeeze the spring, causing the height of the clamping portion to decrease and move into the annular groove. At this time, the container will automatically swing under the action of gravity to shake the sewage inside the container to avoid stratification;

[0022] Step 4: When the container moves to the bottom of the detection head, the lifting seat continues to descend. Through mechanical linkage, the shaking container is clamped and limited from both sides by the clamping arc plate again, and then the detection is carried out. This reciprocating process is repeated until all containers are inspected.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] In the present invention, when the container filled with sewage rotates with the rotating component, the container is blocked by the additional toggle component. At the moment of blocking, the container, which was originally in a vertical state, is forced to change its posture and becomes inclined. As the rotating component continues to operate, the container smoothly crosses the toggle component. During this process, the container will swing regularly. This swing can fully shake the sewage inside the container, effectively break the possible stratification state of the sewage, and make the various substances in the sewage evenly distributed, thereby avoiding the stratification phenomenon from affecting subsequent detection, and effectively ensuring the accuracy of the later detection results. In addition, in the detection link, when the detection head moves downward for detection operation, it will synchronously trigger the clamping component, and the clamping component will firmly clamp the shaking container to prevent the container from colliding with the detection head due to excessive shaking. This not only ensures the safety of the detection equipment, but also ensures that the detection process can be carried out smoothly and stably. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] Please refer to Figures 1 to 11 , the present invention provides a technical solution: A sewage water quality detection device for municipal drainage pipes, including

[0044] A box body 100; A box door 101 that is rotatably connected to the front surface and can be opened and closed; An installation plate 104 is also installed inside the box body 100;

[0045] A detection mechanism is provided inside the box body 100, and this detection mechanism includes:

[0046] The detection assembly comprises a lifting assembly 102 fixed to a mounting plate 104, and a detection portion connected to the lifting assembly 102 for lifting. A cylinder is disposed within the lifting assembly 102, and a lifting base 106 is mounted on the output end of the cylinder. The cylinder is not shown in the figure. Since improvements in this area are not within the scope of the present invention and the structural principles are well known, further description is omitted here.

[0047] The installation component is located below the detection part;

[0048] The toggle assembly is disposed below the mounting assembly. When the mounting assembly rotates, the toggle assembly partially protrudes into the mounting assembly or is concealed on the lower surface of the mounting assembly. When the mounting assembly rotates, the toggle assembly lifts the container 300 by protruding until it is hidden. After being lifted, the container 300 changes from its initial vertical position to an inclined position and swings under gravity, thereby preventing the sewage inside from stratifying due to prolonged standing.

[0049] The clamping assembly 500 is located below the detection assembly and is arranged opposite to the installation assembly. The clamping assembly 500 performs an oblique clamping or oblique separation action toward the inner side of the installation assembly under the lifting movement of the detection assembly. When the container 300 is about to be inspected, in order to prevent the container 300 from still shaking, the container 300 is held tightly by the clamping assembly 500 to achieve positioning.

[0050] In this embodiment, the mounting assembly includes a supporting plate 201 and a turntable 202 mounted above the supporting plate 201, wherein the bottom end of the supporting plate 201 is provided with an integrated driving gear disc 203, and a driving motor, a belt and other structures are also provided inside the box body 100. The belt is driven by the driving motor to rotate, and the belt drives the driving gear disc 203. The driving gear disc 203 realizes the rotation of the supporting plate 201 and the turntable 202, so as to detect all the containers 300 placed on the turntable 202. Since this structure is a prior art and has nothing to do with the improvement of the present invention, it will not be further described here; the surface of the turntable 202 The surface is provided with a plurality of circular holes, and a collar 204 is placed in each circular hole, and a container 300 is inserted into the collar 204, wherein the container 300 is used to place the sewage to be tested. In order to prevent the sewage from overflowing during shaking, the sewage placed in the container 300 shall not exceed two-thirds of its own height. At the same time, this liquid level height is also suitable for the detection needs of conventional laboratories, and the bottom area of the container 300 is a hemispherical arc. This shape setting can ensure that at least one area is supported by the support plate 201, and can also be swung in the later stage. Since the contact area between the support plate 201 and the container 300 is small, the amount of water required for swinging is small. The friction force to be overcome is also small, so it will not affect the normal swing. At the same time, every time the supporting plate 201 rotates, all the containers 300 will be moved to ensure that the container 300 on the farthest side avoids stratification through multiple shifts. A drum spring 205 is also provided on the inner side of the ring 204. The two ends of the drum spring 205 are overlapped on the upper and lower end surfaces of the ring 204 by bending and limiting, and the middle part of the drum spring 205 bulges toward the middle of the ring 204. The middle part of the drum spring 205 is against the surface of the container 300, and the installation of the container 300 is achieved by the elastic pressing of the drum spring 205. It should be noted here that the rebound force of the drum spring 205 should be able to ensure that the container 300 filled with sewage 00 will not be displaced or fall off when swinging; end posts 206 are symmetrically provided on both sides of the collar 204, and holes for the end posts 206 to be inserted are opened on the inner wall of the circular hole on the turntable 202. When the container 300 is dialed, the top of the container 300 will drive the collar 204 to swing synchronously. At this time, the collar 204 will swing around the axis of the end posts 206. The end posts 206 can also ensure that the container 300 can only swing in a single direction. The end posts 206 can be first inserted into the holes on the inner wall of the circular hole, and then the collar 204 equipped with the drum spring 205 and the end posts 206 can be installed by hot melting or other methods to ensure a stable connection.The surface of the supporting plate 201 is provided with arc grooves 201a at equal angles. The number of the arc grooves 201a is equal to the number of the circular holes and the container 300, and the vertical projection of the arc groove 201a passes through the center of the circular hole on the supporting plate 201. The toggle component partially protrudes from the arc groove 201a to the outside of the top of the supporting plate 201. When the supporting plate 201 and the turntable 202 rotate synchronously, the protruding part of the toggle component will contact the bottom of the container 300. At this time, the bottom of the container 300 is blocked. At the same time, the top of the container 300 is not fixed, so the container 300 After being blocked, the bottom of the container 300 changes from its initial vertical position to an inclined position. As the support plate 201 and the turntable 202 continue to rotate, the toggle assembly is hidden under the support plate 201, not blocking the swinging container 300. At this time, the top of the container 300 also rotates synchronously, thereby shaking the sewage inside the container 300 to prevent stratification. At the same time, as the support plate 201 and the turntable 202 rotate, the container 300 itself is also subjected to centrifugal force and swings, which further enhances the shaking effect.

[0051] In this embodiment, the toggle assembly includes a bottom ring 401 placed under the supporting plate 201, and a support 402 is fixed to the bottom of the bottom ring 401, and the support 402 is placed on the inner bottom end surface of the box body 100 to ensure the installation support of the bottom ring 401, and at the same time it will not rotate due to the support plate 201; a tightening member 403 is also provided at an equal angle above the bottom ring 401, and the tightening member 403 is arc-shaped as a whole when viewed from above, and each tightening member 403 corresponds to an arc groove 201a; the tightening member 403 is composed of a tightening portion 403b that passes through the arc groove 201a, and a connecting portion 403a that is integrally formed at both ends of the tightening portion 403b. In the initial state, the tightening portion 403b passes through the arc groove 201a and is in the direction in which the container 300 is about to rotate. Position, when the supporting plate 201 and the turntable 202 rotate synchronously, the container 300 contacts the pressing part 403b in the direction of rotation and is blocked by the pressing part 403b, and a spring 404 is provided between the end of the pressing part 403b and the bottom ring 401; the bottom end surface of the supporting plate 201 is also provided with an annular groove 201b, which is connected to all the arc grooves 201a; after the supporting plate 201 and the turntable 202 continue to rotate, the pressing part 403b will move into the annular groove 201b, at this time the pressing part 403b will squeeze the spring 404, so that the height of the pressing part 403b drops, thereby moving into the annular groove 201b, and the surface of the supporting plate 201 no longer has any structure that restricts the swing of the container 300, and the container 300 automatically swings under the action of gravity.

[0052] In this embodiment, a placement slot 104a is provided at the downward position of the middle part of the mounting plate 104, and the clamping assembly 500 is placed in the placement slot 104a. A movable slot 104b is provided at the top of the placement slot 104a. The detection part includes a lifting seat 106 which is lifted and mounted on the lifting assembly 102. The lifting seat 106 is provided with a detection head 103. A connecting plate 105 is fixed to the bottom of the lifting seat 106. The connecting plate 105 passes through the movable slot 104b and is connected to the clamping assembly 500. The clamping assembly 500 is driven to perform a clamping movement through the connecting plate 105. Since the connecting plate 105 is connected to the lifting seat 106, the container 300 can be clamped and limited in position before detection to avoid the container 300 from continuing to shake and affecting the normal detection.

[0053] In this embodiment, the clamping assembly 500 includes a symmetrically arranged clamping member 501, which is composed of a clamping arc plate 501a, a horizontal plate 501b, and an inclined plate 501c with a rack, wherein the clamping arc plate 501a is clamped to the outside of the container 300 by displacement, thereby limiting the container 300; the horizontal plate 501b connects the clamping arc plate 501a and the inclined plate 501c with a rack, and the three are integrally arranged; the inclined plate 501c with a rack is fitted with the inner wall of the mounting plate 104, that is, the side wall of the placement groove 104a is also inclined, thereby limiting the inclined plate 501c with the rack, and at the same time ensuring that the inclined plate 501 with the rack c extends and retracts in an inclined manner, and an inner plate 504 is also installed on the rear surface of the mounting plate 104. Two transmission members 503 are symmetrically fixed on the top surface of the inner plate 504. The two transmission members 503 are respectively engaged with the inclined plate 501c with a rack at the corresponding position. A driving member is also provided between the two transmission members 503. A spur rack 506 is also passed through the inner plate 504. The inner side surface of the spur rack 506 is engaged with the driving member, and the top of the spur rack 506 is fixed to the connecting plate 105. The lifting and lowering of the connecting plate 105 drives the lifting and lowering of the spur rack 506, and the positive and negative engagement driving of the driving member is realized by the lifting and lowering of the spur rack 506.

[0054] In this embodiment, the driving member includes a transmission column 502 and a bevel gear 502b fixed at both ends of the transmission column 502. A transmission tooth portion 502a is also formed in the middle of the transmission column 502, and the transmission tooth portion 502a is meshed with the spur rack 506. When the spur rack 506 moves downward following the connecting plate 105, the spur rack 506 will drive the transmission tooth portion 502a to rotate, and then the bevel gear 502b drives the transmission member 503 to rotate, and the transmission member 503 drives the inclined plate 501c with the rack to move toward the direction of the container 300. Due to the inclined setting of the inclined plate 501c with the rack, when the container 300 is shaking, the clamping arc plate 501a can clamp and limit the container 300 from both sides.

[0055] In this embodiment, the transfer member 503 includes a driving gear 503b with a shaft. The driving gear 503b rotates around its own shaft, and the shaft of the driving gear 503b is fixedly arranged on the inner plate 504. In addition, a second bevel gear 503a is fixedly arranged on the driving gear 503b. The second bevel gear 503a meshes with the first bevel gear 502b, and the driving gear 503b meshes with the inner wall of the inclined plate 501c with a rack. When the first bevel gear 502b drives the second bevel gear 503a to rotate, the second bevel gear 503a synchronously drives the driving gear 503b. Finally, the driving gear 503b drives the inner wall of the inclined plate 501c with a rack to transmit power, so as to realize the extension and retraction of the entire clamping member 501. The driving gear 503b and the first bevel gear 502b do not contact each other.

[0056] In this embodiment, two support seats 505 are also sleeved on the surface of the transmission column 502. The two support seats 505 are symmetrically arranged at both ends of the transmission tooth part 502a. The transmission column 502 and the support seats 505 are rotatably connected. The installation of the transmission column 502 is realized through the support seats 505, and the bottom of the support seats 505 is installed on the inner plate 504.

[0057] In this embodiment, a rack is formed in the middle and lower area of the straight rack 506, and the upper area of the straight rack 506 is flat. The upper area of the straight rack 506 does not contact the transmission tooth part 502a. When the lifting seat 106 descends, it will drive the detection head 103 and the connecting plate 105 to descend synchronously. At this time, the connecting plate 105 will drive the driving member through the straight rack 506, so as to realize the extension of the clamping member 501. When the clamping arc plate 501a completes the clamping and limiting of the container 300, the detection head 103 does not reach the specified detection position. At this time, the lifting seat 106 continues to descend. At this time, the upper area of the straight rack 506 will descend to the transmission tooth part 502a, and will not drive the transmission tooth part 502a to rotate. At this time, the clamping arc plate 501a will not further press the container 300 tightly to cause movement interference, and the detection head 103 can continue to descend to the specified position normally.

[0058] The present invention also discloses a method for detecting the sewage water quality of a municipal drainage pipeline, including a water quality detection device, and specifically includes the following steps:

[0059] Step 1: Insert the container 300 into the collar 204. At the same time, the container 300 is tightly pressed and limited by the drum spring 205. At this time, apply a pressure greater than the pressing force of the drum spring 205 until the bottom end of the container 300 contacts the supporting plate 201. After all the containers 300 are installed, perform water quality detection;

[0060] Step 2: The lifting seat 106 descends under the action of the lifting assembly 102, sending the detection head 103 into the container 300 to detect the water quality. Meanwhile, when the lifting seat 106 descends, the lifting seat 106 drives the connecting plate 105, the connecting plate 105 drives the straight rack 506, and the straight rack 506 drives the transmission tooth part 502a. At this time, the transmission tooth part 502a drives the entire transmission column 502 to move, and then the bevel gear 502b drives the bevel gear 503a. At this time, the driving gear 503b follows the bevel gear 503a to move, and drives the inclined plate 501c with a rack through the driving gear 503b. At this time, the inclined plate 501c with a rack extends obliquely along the inner wall of the placement groove 104a and clamps and holds the container 300 from both sides through the clamping arc plate 501a below the detection head 103. Subsequently, the lifting seat 106 continues to move downward. At this time, the part of the upper inner wall of the straight rack 506 without a rack no longer drives the transmission tooth part 502a to rotate until the detection head 103 descends to a specified position to detect the water quality;

[0061] Step 3: When the detection is completed, the lifting seat 106 is lifted under the drive of the lifting assembly 102. At this time, the detection head 103 is lifted and separated from the container 300, and the connecting plate 105 synchronously drives the straight rack 506. The straight rack 506 reversely drives the transmission tooth part 502a, realizing that the clamping member 501 retracts obliquely in a direction away from both sides of the container 300. Then, the supporting plate 201 and the turntable 202 are rotated. At this time, the bottom of the subsequent container 300 to be detected will be blocked by the connecting part 403a, and the top of the container 300 will drive the collar 204 to tilt synchronously due to the tilt change at the bottom, causing the container 300 itself to tilt until the tilt angle of the container 300 becomes larger and crosses the abutting part 403b. After the supporting plate 201 and the turntable 202 continue to rotate, the abutting part 403b will move into the annular groove 201b, and the abutting part 403b will squeeze the spring 404, causing the height of the abutting part 403b to decrease and move into the annular groove 201b. At this time, the container 300 will swing automatically under the action of gravity, shaking the sewage inside the container 300 to avoid stratification;

[0062] Step 4: When the container 300 moves below the detection head 103, the lifting seat 106 continues to descend. Through mechanical linkage, the shaking container 300 is clamped and limited from both sides again through the clamping arc plate 501a, and then the detection is carried out. This process is repeated until all the containers 300 are detected.

The scope of the present invention is defined by the appended claims and their equivalents.

10. A method for detecting the sewage quality of a municipal drainage pipeline, including the water quality detection device described in any one of claims 1 to 9, characterized in that: The specific steps include: Step 1: Insert the container into the collar. At the same time, the container is tightened by the drum spring. At this time, apply a pressure greater than the drum spring until the bottom of the container contacts the support plate. After all containers are installed, perform water quality testing. Step 2: The lifting seat descends under the action of the lifting assembly, and the detection head is sent into the container to test the water quality. At the same time, as the lifting seat descends, the lifting seat drives the connecting plate, and the connecting plate drives the spur rack, which drives the transmission tooth part through the spur rack. At this time, the transmission tooth part drives the entire transmission column to move, and then the bevel gear 1 drives the bevel gear 2. At this time, the driving gear follows the movement of the bevel gear 2 and drives the inclined plate with the rack through the driving gear. At this time, the inclined plate with the rack extends obliquely along the inner wall of the placement groove and is clamped from both sides of the container below the detection head through the clamping arc plate. Then the lifting seat continues to move downward. At this time, the part of the upper inner wall of the spur rack that does not have a rack no longer drives the transmission tooth part to rotate until the detection head descends to the designated position to test the water quality. Step 3: After the detection is completed, the lifting seat is lifted under the drive of the lifting component. At this time, the detection head is lifted and separated from the container, and the connecting plate synchronously drives the straight rack. The straight rack reversely drives the transmission tooth part, so that the clamping member retracts obliquely in the direction away from both sides of the container. Then, the supporting plate and the turntable are rotated. At this time, the bottom of the container to be detected subsequently will be blocked by the connecting part, and the top of the container will drive the collar to tilt synchronously due to the tilt change of the bottom, so that the container itself will tilt until the tilt angle of the container becomes larger and exceeds the abutting part. After the supporting plate and the turntable continue to rotate, the abutting part will move into the annular groove, and the abutting part will squeeze the spring, causing the height of the abutting part to decrease and move into the annular groove. At this time, the container will swing automatically under the action of gravity, shaking the sewage inside the container to prevent stratification; Step 4: When the container moves below the detection head, the lifting seat continues to descend. Through mechanical linkage, the shaking container is clamped and limited from both sides by the clamping arc plate again, and then the detection is carried out. This process is repeated until all containers are detected.
