Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the utility model. The experimental methods in the following embodiments are all conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified.

[0035] like Figure 1-Figure 5 In this embodiment, it includes: a gantry vehicle 1 rollingly installed on the top of the advection sedimentation tank 2 and a sludge suction unit 3 arranged at the bottom of the gantry vehicle 1;

[0036] It should be noted that the horizontal flow sedimentation tank 2 is laid with tracks along the moving direction of the gantry vehicle 1 , and the gantry vehicle 1 moves on the tracks through the rolling wheels included in the moving assembly 11 .

[0037] The mud suction unit 3 includes a hanger 37, a mud level meter 32 respectively fixed to the front and rear sides of the hanger 37, and a scraper 34 and a mud suction nozzle 36 arranged at the bottom of the hanger 37;

[0038] It should be noted that the mud suction nozzle 36 is in the shape of a flat duckbill.

[0039] It should be noted that the top of the hanger 37 is connected to the bottom of the gantry truck, and the mud level meter 32 is arranged on the front and rear sides of the hanger 37 through a connecting plate. At the same time, the positions of the mud level meter 32 and the mud suction nozzle 36 correspond to each other.

[0040] It should be noted that the mud suction units 3 are three groups, which are arranged in a linear array at the bottom of the gantry vehicle, and each group has multiple groups of scrapers 34 and three mud suction nozzles 36 .

[0041] Specifically, the mud level meter 32 is used to detect the mud level at the current position of the gantry truck 1, and then feed the data back to the control device. The control device chooses to turn on or off the mud suction pump according to the current mud level.

[0042] A groove 21 is arranged at the bottom of the advection sedimentation tank 2, an infrared device 23 is arranged outside the advection sedimentation tank 2, and an electric angle valve 22 is arranged directly below the infrared device 23; the direction of the groove 21 is perpendicular to the moving direction of the gantry vehicle 1, a perforated pipe 20 is arranged in the groove 21, and the perforated pipe 20 extends outside the advection sedimentation tank 2 and is connected to the electric angle valve 22;

[0043] Specifically, the scraper 34 has two functions. One part pushes the sludge to the sludge suction nozzle 36, and then the sludge is transported to the sludge discharge pipe 31 through the sludge suction pump 33 arranged on the sludge suction pipe 35, and finally the sludge discharge pipe 31 transports the sludge to the outside of the horizontal flow sedimentation tank 2; the other part is to push the sludge along with the gantry vehicle 1 through the scraper, and finally send it to the perforated pipe 20 in the groove 21, and finally the opened electric angle valve 22 sends the sludge out of the horizontal flow sedimentation tank 2.

[0044] An infrared baffle 30 is provided at the outer end of the gantry vehicle 1 .

[0045] Specifically, the infrared baffle 30 is installed at the end of the gantry truck 1. When the gantry truck 1 starts to move, the baffle moves synchronously. When the infrared baffle 30 reaches the infrared device 23, the baffle transmits a signal to the infrared device 23. Then the control device determines whether the electric angle valve 22 needs to be opened based on the signal and the current mud level data of the mud level meter 32. If the mud level data is high, the electric angle valve 22 is opened, and finally the sludge in the perforated pipe 20 is sent out of the pool.

[0046] In this embodiment, multiple groups of scrapers 34 are respectively set on the front and rear sides of the hanger 37, and the front and rear adjacent scrapers form a triangle or diamond shape. The scrapers 34 after being assembled are V-shaped, and the mud suction nozzles 36 are set at the intersection of the V shape. Multiple mud suction nozzles 36 are connected by mud suction pipes 35.

[0047] Specifically, the triangular or diamond shape formed by the scrapers facilitates the gantry vehicle 1 to reciprocate along the track to suck mud for operation.

[0048] In this embodiment, a speed reducer 10 is provided on the gantry truck 1, and the traveling speed of the gantry truck 1 is controlled by frequency conversion regulation.

[0049] In this embodiment, the mud discharge pipe 31 is arranged at the bottom of the gantry vehicle 1 and extends out of the advection sedimentation tank 2 .

[0050] It should be noted that the mud discharge pipe 31 is an L-shaped mud discharge pipe, and the infrared baffle 30 is transversely fixed to the pipe wall of the L-shaped mud discharge pipe 31 close to the outlet and at a position combined with the infrared device 23 .

[0051] In this embodiment, a sludge concentration meter and an electric valve are respectively provided at the outlet of the sludge discharge pipe 31, and the sludge concentration meter adjusts the valve according to the concentration of the sludge.

[0052] Specifically, when the control system receives data from the sludge concentration meter, it can adjust the electric valve to reduce the waste of water resources in the sludge.

[0053] In this embodiment, the mud suction pipe 35 of each mud suction unit 3 is connected to the mud discharge pipe 31 .

[0054] It should be noted that, because there are differences in mud suction between each group of mud suction units 3 , in order to avoid mutual interference between the groups, each group of mud suction units 3 corresponds to its own independent mud discharge pipe 31 .

[0055] In this embodiment, the infrared device 23 is an infrared photoelectric sensor.

[0056] Specifically, the infrared photoelectric sensor consists of two parts, one is a transmitter and the other is a receiver. The transmitter is installed on the infrared baffle 30, and the receiver is set on the outer wall of the horizontal flow sedimentation tank 2. When the infrared baffle 30 moves near the receiver, the signal emitted by the transmitter is received by the receiver and then fed back to the control device.

[0057] It should be noted that the power of the device is driven by the distribution box 12.

[0058] It should be noted that the control device is not shown in the figure.

[0059] Working principle:

[0060] (1) Setting and movement of the gantry: The gantry 1 is installed on the top of the horizontal flow sedimentation tank 2 and moves on the track laid on the top of the horizontal flow sedimentation tank. The movement of the gantry is achieved by the rolling wheels at its bottom. The speed of the gantry can be adjusted by the reducer 10 set on the top. The reducer is connected to the frequency converter to adjust the travel speed according to different silt conditions.

[0061] (2) Composition and function of the mud suction unit: The bottom of the gantry truck is connected with a mud suction unit 3, which is composed of a hanger 37. Mud level meters 32 are fixed on the front and rear sides of the hanger 37, and a scraper 34 and a mud suction nozzle 36 are arranged at the bottom. The mud level meter 32 is used to detect the mud level at the current location of the gantry truck and feed the data back to the control device.

[0062] (3) Concentration and suction of sludge: The scraper 34 is an inwardly inclined structure used to gather the sludge to the middle. The sludge suction nozzle 36 is located at the intersection of the V-shape, and the sludge suction pipe 35 transports the sucked sludge to the sludge discharge pipe 31.

[0063] (4) Transportation and discharge of sludge: The sludge discharge pipe 31 runs through the bottom of the gantry vehicle 1 and extends to the outside of the horizontal flow sedimentation tank 2. The sludge discharge pipe is an L-shaped structure. The sludge suction pump 33 is connected to the top of the sludge suction nozzle 36. Once turned on, the sucked sludge can be transported to the outside of the horizontal flow sedimentation tank through the sludge discharge pipe.

[0064] (5) Function of infrared control device: infrared device 23 is arranged outside the horizontal flow sedimentation tank and used in conjunction with electric angle valve 22. When the gantry truck 1 moves, the infrared baffle 30 at the outer end of the gantry truck transmits a signal to the infrared device 23, thereby triggering a signal to be sent to the control device. The control device, based on the mud level data of the current mud level meter 32, opens the electric angle valve 22 if it is high, allowing the mud to be discharged from the inside of the perforated pipe 20 to the outside.

[0065] (6) The control device provides two control schemes:

[0066] First: After receiving the data from the mud level meter 32, the control device will adjust the speed of the gantry truck 1 and the switch of the mud suction pump according to the height of the mud. In areas with high mud height, the gantry truck 1 moves forward slowly and the mud suction pump is turned on; when the mud level is medium, the gantry truck 1 moves forward at a medium speed and the mud suction pump is still turned on; and in areas with low mud level, the gantry truck 1 moves forward quickly and the mud suction pump is turned off;

[0067] Second: After the control device receives the data from the mud level meter 32 in the moving direction, it starts to judge. When the mud level data is too low, the gantry crane 1 will stop moving forward and end the mud discharge. At the same time, when the number of back and forth operations of the gantry crane 1 reaches the number limited by the control device, the gantry crane 1 is forced to perform a full mud discharge operation.

[0068] (7) Design of the groove 21 and the perforated pipe 20: The groove 21 at the bottom of the advection sedimentation tank is perpendicular to the direction of travel of the gantry vehicle. The groove is equipped with a perforated pipe 20, which extends outside the advection sedimentation tank and is connected to the electric angle valve 22. When the electric angle valve 22 is opened, the sludge in the perforated pipe 20 is sent out of the tank to help clean the advection sedimentation tank.

[0069] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
