Through sewage detection, pollution sources can be discovered in a timely manner, the effects of sewage treatment can be evaluated, and it can be ensured that sewage discharge meets relevant standards and regulatory requirements. Sampling devices are required in sewage detection.

[0003] The existing sampling devices for sewage detection are not convenient for sequential continuous sampling, with a relatively long sampling time, and cannot avoid excessive sewage in the test tube, resulting in sewage spilling and contaminating the equipment. Content of the Utility Model

The vertical rod is sleeved at the center of the inner bottom of the hollow socket through a connecting bearing. The upper end of the vertical rod is sleeved with an adjusting sleeve, and one side of the adjusting sleeve is sleeved with an injection cylinder through a connecting block and a limiting sleeve. A piston is sleeved inside the injection cylinder, and one end of the piston is connected to a piston push rod, and the piston push rod penetrates through one end of the top of the injection cylinder;

The top of the top plate is provided with test tube fixing holes at equal distances along the radial direction of the top plate, and polyurethane elastic sleeves are bonded inside the test tube fixing holes.

[0007] By adopting the above technical solution, the multi-chamber sampling device for sewage detection can perform sequential continuous sampling, shorten the sampling time, and can avoid excessive sewage in the test tube, resulting in sewage spilling and contaminating the equipment.

[0008] Specifically, a liquid infusion tube is arranged on one side of the top end of the injection cylinder, and a control valve is arranged on the liquid infusion tube.

[0009] By adopting the above technical solution, the control valve is opened, and the water source to be sampled is injected into the injection cylinder through the liquid infusion tube, which is convenient for centralized storage of the water sample.

[0011] Specifically, a locking bolt is installed on one side of the adjusting sleeve through a bolt hole.

[0012] By adopting the above technical solution, loosening the locking bolt enables the adjusting sleeve to slide on the vertical rod, thereby adjusting the height of the injection cylinder to meet different usage requirements.

[0013] Specifically, a bushing is sleeved at the axis of the top plate and the vertical rod passes through the bushing.

[0014] Specifically, both ends of the support spring are respectively connected to the top plate and the hollow socket through positioning pieces and positioning screws.

[0015] Advantages of the present utility model:

[0016] (1) For the multi-chamber sampling device for sewage detection of the present utility model, the test tubes to be sampled are inserted into the test tube fixing holes. The polyurethane elastic sleeve has high elasticity and good toughness, which plays a role in limiting the test tubes. Rotate the handwheel so that the liquid outlet of the injection cylinder is facing the top of the test tube to be sampled. Pull the piston push rod to lift the piston to the highest position. Open the control valve and use the infusion tube to inject the water source to be sampled into the injection cylinder for convenient centralized storage of the water sample. The sampling personnel push the piston push rod downward to drive the piston to move downward, so that the sewage water sample in the injection cylinder enters the test tube from the liquid outlet.

[0017] (2) For the multi-chamber sampling device for sewage detection of the present utility model, when the test tube directly below is filled with the water sample, rotate the handwheel in sequence so that the liquid outlet is above different test tubes, thereby continuously sampling in sequence, shortening the sampling time, and avoiding excessive sewage in the test tube, resulting in sewage spillage and equipment pollution. Manually push the top plate downward on both sides, and under the action of the elastic force of the support spring, the test tube vibrates up and down to oscillate the sewage water sample in the test tube evenly, improving the detection accuracy of the sewage.

[0024] In order for the multi-chamber sampling device for sewage detection to be able to sample continuously in sequence, shorten the sampling time, and avoid excessive sewage in the test tube, resulting in sewage spillage and contamination of the equipment, as Figures 1-3 shown, a multi-chamber sampling device for sewage detection according to the present utility model includes a hollow socket 2, a top plate 5, a vertical rod 16 and an injection cylinder 8. The vertical rod 16 is sleeved with a connecting bearing 1 at the center of the inner bottom of the hollow socket 2. The upper end of the vertical rod 16 is sleeved with an adjusting sleeve 14, and one side of the adjusting sleeve 14 is sleeved with an injection cylinder 8 through a connecting block 9 and a limiting sleeve. A piston 19 is sleeved in the injection cylinder 8. One end of the piston 19 is connected to a piston push rod 12, and the piston push rod 12 penetrates through one end of the top of the injection cylinder 8;

[0025] The top periphery of the hollow socket 2 is connected to the top plate 5 through a support spring 4. The top of the top plate 5 is provided with test tube fixing holes 18 at equal distances along the radial direction of the top plate 5. A polyurethane elastic sleeve 17 is bonded in the test tube fixing holes 18.

[0026] During use, the multi-chamber sampling device for sewage detection can sample continuously in sequence, shorten the sampling time, and avoid excessive sewage in the test tube, resulting in sewage spillage and contamination of the equipment.

[0027] Exemplarily, as Figure 1 shown, the present utility model further includes that a liquid infusion tube 10 is provided on one side of the top end of the injection cylinder 8, and a control valve 11 is provided on the liquid infusion tube 10.

[0028] During use, the control valve 11 is opened, and the water source to be sampled is injected into the injection cylinder 8 through the liquid infusion tube 10 to facilitate centralized storage of the water sample.

[0029] Exemplarily, as Figure 1 shown, the present utility model further includes that a hand wheel 13 is welded to the top of the vertical rod 16, and a liquid outlet pipe 7 is provided at the bottom of the injection cylinder 8.

[0030] When in use, the hand wheel 13 is turned so that the liquid outlet 7 of the injection barrel 8 is directly opposite to the top of the sampling test tube.

[0031] For example, Figure 1 As shown, the utility model also includes that a locking bolt 15 is installed on one side of the adjustment sleeve 14 through a bolt hole.

[0032] When in use, the locking bolt 15 is loosened to allow the adjusting sleeve 14 to slide on the vertical rod 16, thereby adjusting the height of the injection cylinder 8 to meet different usage requirements.

[0033] For example, Figure 1 As shown, the utility model also includes that a shaft sleeve 6 is sleeved at the axis center of the top plate 5 and the vertical rod 16 passes through the shaft sleeve 6.

[0034] When in use, the vertical rod 16 is allowed to rotate stably to reduce shaking.

[0037] When the utility model is used, the test tubes to be sampled are inserted into the test tube fixing holes 18, and the polyurethane elastic sleeve 17 has high elasticity and good toughness, which has the effect of limiting the sampling test tubes;

[0038] Turn the hand wheel 13 to make the liquid outlet 7 of the injection cylinder 8 face the top of the sampling tube, pull the piston push rod 12 to lift the piston 19 to the highest end, open the control valve 11 and use the infusion tube 10 to inject the water source to be sampled into the injection cylinder 8 to facilitate the centralized storage of water samples;

[0039] The sampling personnel pushes the piston push rod 12 downward to drive the piston 19 to move downward, so that the sewage sample in the injection cylinder 8 enters the test tube from the liquid outlet 7. When the test tube directly below is full of water samples, the hand wheel 13 is turned in sequence to make the liquid outlet 7 above different test tubes, so as to sample continuously in sequence, shorten the sampling time, and avoid excessive sewage in the test tube, causing sewage to spill and cause equipment pollution;

[0040] The top plate 5 is manually pushed downward on both sides, and the test tube is vibrated up and down under the elastic force of the support spring 4, so that the sewage sample in the test tube is vibrated evenly, thereby improving the detection accuracy of sewage.
