Description

Technical Field

[0001] The utility model relates to the technical field of sewage sampling, in particular to a sewage detection and sampling device for construction sites. Background Technique

[0002] Classified by the source of sewage, sewage treatment is generally divided into industrial production sewage treatment and domestic sewage treatment; with the rapid rise of modern industrialization, more and more construction projects have emerged. During the project period, a large amount of sewage is often discharged. Therefore, it is necessary to use a sewage detection device to detect the sewage, and the sewage that meets the standards after detection can be discharged into the natural environment.

[0003] Currently, the commonly used sewage detection equipment usually consists of a sampler and a water quality detector. The sampler samples and collects the sewage, and then the water quality detector detects the sewage in the sampler.

[0004] However, due to the long sewage discharge time at construction sites, the intermittent and long-term discharge during construction, it is necessary to sample regularly and periodically. After multiple samplers sample regularly, due to the lack of a sorting device and time differentiation, multiple samplers are prone to confusion, resulting in detection errors.

Specific embodiments

[0022] An embodiment of the utility model provides a sewage detection and sampling device for a construction site, as follows Figures 1-3 shown, which includes a base 1, a fixed seat 2, a turntable 3, a stepper motor 5, a blanking cylinder 6, a conveyor belt 7 and a support bottom plate 8.

[0023] At least four support legs 11 are provided at the bottom of the base 1, and universal wheels are provided on each support leg 11. A handle can be provided on the base 1 for facilitating the pushing of the device.

[0024] The fixed seat 2 is in a circular groove shape and is fixed on the base 1. The height of the groove in the fixed seat 2 is slightly greater than the height of the sampling cup 19. The turntable 3 is pivotally connected in the fixed seat 2, and the edge of the turntable 3 is in clearance fit with the fixed seat 2. The stepper motor 5 is provided on the base 1 and is connected to the rotating shaft of the turntable 3. The stepper motor 5 is used to drive the turntable 3 to rotate. The stepper motor 5 can be controlled by an operator. A plurality of accommodating grooves 4 with open outsides are circumferentially formed on the turntable 3. In this embodiment, the number of the accommodating grooves 4 is four. The four accommodating grooves 4 are equally angularly distributed around the center of the turntable 3, and one sampling cup 19 can be accommodated in the accommodating groove 4. The sampling cups 19 are vertically stacked in the blanking cylinder 6.

[0025] Three sequential accommodating grooves 4 correspond to three workstations. The first workstation is used for blanking the sampling cup 19. Specifically, the blanking cylinder 6 is fixed on the base 1 through a bracket. The outlet height of the blanking cylinder 6 is flush with the top of the fixed seat 2, and the bottom outlet of the blanking cylinder 6 corresponds to the accommodating groove 4 at the first workstation. The sampling cup 19 can leak out from the bottom of the blanking cylinder 6 into the accommodating groove 4.

[0026] The accommodating groove 4 at the second workstation corresponds to the sampling pipe 20 of the sewage pipe. The sampling pipe 20 extends from the construction site sewage discharge pipe, and a valve is provided at the end of the sampling pipe 20, which is controlled by the sampling personnel. The accommodating groove 4 at the corresponding third workstation of the fixed seat 2 is in an open shape, and the width of the open mouth is slightly greater than the diameter of the sampling cup 19. Here, it is connected to the conveyor belt 7. The end of the conveyor belt 7 covers the accommodating groove 4, and the top conveying surface of the conveyor belt 7 is slightly lower than the bottom of the fixed seat 2. The support bottom plate 8 is connected to the end of the conveyor belt 7. The conveyor belt 7 is an existing commercially available product and is an electric conveyor belt.

[0027] As Figure 3 shown, guiding side plates 9 for guiding are provided on both sides of the support bottom plate 8. The distance between the two guiding side plates 9 is slightly greater than the diameter of the sampling cup 19, and one end of the guiding side plate 9 is connected to the fixed seat 2.

[0028] A top plate 10 is provided at the end of the support bottom plate 8. An alarm 17 is provided on the base 1 or the top plate 10. A trigger switch 18 corresponding to the sampling cup 19 is provided on the top plate 10. The trigger switch 18 is used to trigger the alarm 17. The alarm 17 is a buzzer. When the first sampling cup 19 touches the trigger switch 18, the alarm 17 gives an alarm to remind the sampling personnel.

[0029] In order to enable the sampling cup 19 to smoothly enter the accommodation groove 4, a pressing mechanism for pressing down the sampling cup 19 is provided on the blanking cylinder 6.

[0030] Specifically, as Figure 1 shown, the pressing mechanism includes a pressing plate 12, a support plate 13, and a spring 14. The support plate 13 is fixed on the bracket and is located above the blanking cylinder 6. The pressing plate 12 is vertically slidably fitted in the blanking cylinder 6, and the top is connected to the support plate 13 through the spring 14. The bottom of the pressing plate 12 contacts the sampling cup 19. A guiding groove 15 is vertically formed on the blanking cylinder 6, and a slider 16 slidably fitted on the guiding groove 15 is provided on the pressing plate 12. When the sampling cup 19 descends, the pressing plate 12 can be pressed down under the action of the spring 14, so that the sampling cup 19 has a downward thrust.

[0031] Working principle: First, pull up the pressing plate 12, and then stack a plurality of sampling cups 19 vertically in the blanking cylinder 6. After the first sampling cup 19 enters the accommodation groove 4, the stepping motor 5 drives the turntable 3 to rotate 90°, so that it rotates to the second working position, and then discharges the sewage sample at the corresponding time point onto the sampling cup 19. Then the stepping motor 5 continues to drive the turntable 3 to rotate 90°, drives the sampled sampling cup 19 onto the conveyor belt 7, and the conveyor belt 7 conveys the sampling cup 19 to the support bottom plate 8. After multiple samplings, a plurality of sampling cups 19 are arranged in chronological order on the support bottom plate 8. After the stage sampling is completed, the sampling personnel can number the sampling cups 19 on the support bottom plate 8 in order, which is convenient for detecting the sewage at the corresponding time points.
