Technical Field

[0001] The utility model relates to the technical field of black and odorous water overflow pollution, in particular to a sampling device used for black and odorous water overflow pollution research. Background Art

[0002] As one of the main drainage systems, the combined sewer system is widely used in my country and other parts of the world. Combined sewer network overflow is a key potential risk of urban water pollution during the rainy season. Combined sewers collect rainwater, domestic sewage, and industrial wastewater. When the amount of water transported on rainy days exceeds the sewage receiving capacity of the pipe network, overflow will occur. The overflow sewage exceeds the self-purification capacity of the receiving water body, and the black and smelly water produced seriously affects the urban ecological environment.

[0003] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the occurrence time of combined sewer network overflow events is greatly affected by rainfall. Since the rainfall time and the pipeline overflow time are difficult to grasp, manual monitoring cannot realize the study of combined sewer overflow pollution. As a result, there is a general lack of understanding of the overflow time, overflow intensity and overflow impact of combined sewer overflows, which has caused great obstacles to the proposal of overflow pollution control strategies for black and odorous water bodies. Therefore, in response to the above problems, a sampling device for the study of overflow pollution of black and odorous water bodies is proposed. Utility Model Content

[0006] The effect achieved by the above components is: it achieves the effect of protecting the water absorption end of the sampling tube, avoiding the situation in which the sampling tube is blocked and unable to sample during the process of absorbing water in the overflow well of the pipeline due to the accumulation of domestic garbage floating on the surface of the sewage pipe and pollutants at the bottom when absorbing water, thereby improving the practicality of the device.

[0009] Preferably, one end of the screw rod away from the clamping block is fixedly connected to a handle, and the clamping block is semicircular in shape.

[0010] The effect achieved by the above components is to facilitate the staff to stably and accurately control the position and fixing degree of the clamping block.

[0011] Preferably, a sealing gasket is fixedly connected to the surface of the clamping block, and the sealing gasket is made of rubber.

[0012] The effect achieved by the above components is: preventing water from seeping from the connection between the hollow rod and the sampling tube.

[0015] Preferably, two slide grooves are provided on the surface of the fixing frame, and the inner surfaces of the two slide grooves of the fixing frame are both slidably connected to limit rods, and the two limit rods are both fixedly connected to the liquid level detector.

[0016] The effect achieved by the above components is: avoiding the situation where the liquid level detector rotates with the rotation of the threaded rod and causes position deviation.

The screw rod 12 is rotated in the long board 11, and the screw rod 12 drives the clamping block 13 to move, and the clamping block 13 drives the slide bar 14 to slide in the long board 11, so that the clamping block 13 is prevented from rotating with the rotation of the screw rod 12, and the stability of the device is improved. The end of the screw rod 12 away from the clamping block 13 is fixedly connected with a handle 15, and the shape of the clamping block 13 is semicircular. The handle 15 is rotated to drive the screw rod 12 to rotate in the long board 11, so that the staff can stably and accurately control the position and fixing degree of the clamping block 13. The surface of the clamping block 13 is fixedly connected with a sealing gasket 16, and the material of the sealing gasket 16 is rubber. The screw 12 drives the clamping block 13 to move, and the clamping block 13 drives the sealing pad 16 to move, thereby preventing water from seeping from the connection between the hollow rod 9 and the sampling tube 2. A fixing frame 8 is installed on the surface of the liquid level detector 1, and a mounting plate 17 is fixedly connected to the surface of the fixing frame 8. A servo motor 18 is fixedly connected to the surface of the mounting plate 17. A threaded rod 19 is fixedly connected to the output end of the servo motor 18, and the liquid level detector 1 is threadedly connected to the surface of the threaded rod 19. The servo motor 18 is started, and the servo motor 18 drives the threaded rod 19 to rotate, and the threaded rod 19 drives the liquid level detector 1 to move, thereby achieving the effect of adjusting the position of the liquid level detector 1, avoiding the need for the staff to remove the fixing frame 8 from the wall when adjusting the position of the liquid level detector 1, and improving the convenience of the device. Two slide grooves are provided on the surface of the fixing frame 8, and the inner surfaces of the two fixing frame 8 slide grooves are both slidably connected to the limit rods 20, and the two limit rods 20 are both fixedly connected to the liquid level detector 1.

[0028] Working principle: an ultrasonic sensor is provided below the liquid level detector 1. The ultrasonic wave emitted by the ultrasonic sensor is used to automatically calculate the distance, and the control circuit outputs an analog signal to automatically transmit the liquid level data to the liquid level display 4 and transmit it to the big data platform via a satellite signal, so that the user can judge the frequency of overflow in real time. The tipping bucket rain gauge 3 shown can realize automatic recording of rainfall. Rainwater enters the water diversion funnel from the water receiver and then flows into the tipping bucket. When the amount of accumulated water reaches the set control threshold, the tipping bucket flips left and right, and the contact switch converts the number of tipping bucket flips into an electrical signal and transmits it to the recorder, thereby transmitting the rainfall data to the big data platform. The user can judge in real time whether the rainfall triggers sampling, and distinguish and record samples in a timely and accurate manner. The controller 5 shown is a high-definition color display screen, which can provide flexible display and operation space, so that the user can control the sampling conditions. When the rainfall recorded by the tipping bucket rain gauge 3 reaches the sampling threshold set by the controller 5, the automatic sampler will be triggered to work. Under the action of the peristaltic pump, the overflow sewage of the pipe network enters the automatic sampler through the sampling tube 2 for automatic sample collection. In order to extend the service life of this black and odorous water overflow pollution research device, a square stainless steel shell is provided on the outside of the device, and the circuits of the above components are connected inside the shell. When the staff needs to replace the filter chamber 10 of the sampling tube 2, the screw 12 is driven to rotate in the long plate 11 by rotating the handle 15, and the screw 12 drives the clamping block 13 to move, and the clamping block 13 drives the sealing gasket 16 to move, and the clamping block 13 drives the sliding rod 14 to slide in the long plate 11 until the sealing gasket 16 is no longer in contact with the surface of the sampling tube 2. When the staff needs to adjust the position of the liquid level detector 1, the servo motor 18 is started, and the servo motor 18 drives the threaded rod 19 to rotate, and the threaded rod 19 drives the liquid level detector 1 to move, and the liquid level detector 1 drives the limit rod 20 to slide on the inner surface of the slide groove of the fixing frame 8.
