[0029] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the specific embodiments of the present utility model will be described in detail below with reference to the accompanying drawings of the specification.

[0030] Embodiment 1

[0031] Refer to Figures 1-5 , which is the first embodiment of the present utility model, and provides a sewage sampling device for environmental protection monitoring. Such a sewage sampling device for environmental protection monitoring includes a floating block 1. An installation vertical plate 2 is installed at the bottom of the floating block 1. A sewage pump suction assembly 3 is detachably installed on one side of the installation vertical plate 2, and the distance between adjacent two sewage pump suction assemblies 3 is adjustable;

[0032] A guide rail 5 is installed on the other side of the installation vertical plate 2. A slide block 6 is slidably installed on the guide rail 5, and the length of the slide block 6 is greater than the length of the guide rail 5. At the same time, a through hole for the slide block 6 to pass through is opened at the top of the floating block 1. A pull ring plate 62 is installed at the top of the slide block 6. A pump suction drive assembly 4 that is detachably installed and is clamped with the sewage pump suction assembly 3 is installed on the side of the slide block 6 away from the installation vertical plate 2.

[0033] The sewage pump suction assembly 3 includes a first connecting strip 31. A material taking cylinder 34 is clamped on the side of the first connecting strip 31 away from the installation vertical plate 2. A piston rod 37 is arranged inside the material taking cylinder 34. A piston head is installed at the bottom of the piston rod 37. A disc 38 is fixed at the top of the piston rod 37. An L-shaped pipe 36 is installed at the water inlet end at the bottom of the material taking cylinder 34.

[0034] A U-shaped clamp 33 is installed on the side of the first connecting strip 31 close to the material taking cylinder 34, and the material taking cylinder 34 is clamped inside the U-shaped clamp 33 to fix the material taking cylinder 34 inside the U-shaped clamp 33.

[0035] Retaining rings 35 are sleeved on the upper and lower positions of the outer wall of the material taking cylinder 34, and an annular cavity for limiting the U-shaped clamp 33 is formed between the two retaining rings 35. The U-shaped clamp 33 is located between the two adjacent ones 25, ensuring that each time the U-shaped clamp 33 clamps the material taking cylinder 34, it is in the same position, improving the accuracy of the water intake point position and also facilitating the installation and disassembly between the first connecting strip 31 and the material taking cylinder 34.

[0036] Both ends of the first connecting bar 31 on the side far away from the U-shaped card 33 are provided with second threaded holes. Two rows of fixing through holes 21 are provided on both sides of one side of the installation vertical plate 2, and the distances between two adjacent fixing through holes 21 on the same side are the same. The first connecting bar 31 is threadedly installed with the first fixing bolts 32 through the second threaded holes thereon, and the first fixing bolts 32 pass through the interiors of the fixing through holes 21. By installing the first connecting bar 31 between two fixing through holes 21 at different height positions, the position of the sewage pump suction assembly 3 is adjusted, so as to adjust the water intake point of the sewage pump suction assembly 3 and the distance between two adjacent sewage pump suction assemblies 3, and perform adaptive adjustment according to the actual water intake point requirements, which is flexible and practical.

[0037] During the use process, the process of installing the sewage pump suction assembly 3 on the installation vertical plate 2 is as follows:

[0038] Align the two second threaded holes on the first connecting bar 31 with the two fixing through holes 21 respectively to make them concentric. After the first fixing bolts 32 pass through the fixing through holes 21, they are threadedly connected with the second threaded holes, so that the first connecting bar 31 is detachably installed on the installation vertical plate 2. By installing the first connecting bar 31 between two fixing through holes 21 at different height positions, the position of the sewage pump suction assembly 3 is adjusted, so as to adjust the water intake point of the sewage pump suction assembly 3 and the distance between two adjacent sewage pump suction assemblies 3.

[0039] Embodiment 2

[0040] Refer to Figures 1-5 , which is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is:

[0041] The pump suction drive assembly 4 includes a second connecting bar 41 detachably installed on the side of the slider 6 far away from the installation vertical plate 2. Both ends of the second connecting bar 41 on the side close to the installation vertical plate 2 are installed with fixing bars 43. U-shaped channels 44 are installed on the opposite end faces of the two fixing bars 43, and the disc 38 is stuck between the two U-shaped channels 44. By the clamping connection between the pump suction drive assembly 4 and the sewage pump suction assembly 3, multiple sewage pump suction assemblies 3 can be simultaneously driven for simultaneous sampling operations, improving the sampling work efficiency.

[0042] One row of first threaded holes 61 is provided on both sides of the side of the slider 6 far away from the installation vertical plate 2. The second connecting bar 41 is provided with second fixing bolts 42 through two through holes opened thereon, and the second fixing bolts 42 pass through the interiors of the through holes and are threadedly connected with the first threaded holes 61.

[0043] After the sewage pump suction assembly 3 is installed, the pump suction drive assembly 4 is correspondingly installed for the installation position of each sewage pump suction assembly 3. The installation process of the pump suction drive assembly 4 is as follows:

[0044] Align the two perforations on the second connecting bar 41 with the two first threaded holes 61, and thread the second fixing bolt 42 through the two perforations and then thread it with the first threaded hole 61, then fix the second connecting bar 41 on the slider 6, and make the disc 38 stuck between the two U-shaped bin channels 44 on both sides. The detachable installation of the pump suction drive assembly 4 is adaptively adjusted according to the installation positions of the sewage pump suction assembly 3, corresponding one by one to ensure accurate clamping between the sewage pump suction assembly 3 and the pump suction drive assembly 4.

[0045] The number of the first threaded holes 61 in a row is the same as that of the fixed perforations 21 in a row, and the distance between two adjacent fixed perforations 21 in the same row is the same as the distance between two adjacent first threaded holes 61 in the same row.

[0046] During use, after the sewage pump suction assembly 3 and the pump suction drive assembly 4 are installed, place the device in water. Since the floating block 1 makes the device float on the water surface, when the floating block 1 is stationary, pressing down the pull ring plate 62 drives the slider 6 to move downward. The slider 6 drives the disc 38 to move downward through the pump suction drive assembly 4, and the piston head presses downward inside the retaining ring 35, pushing the air inside the material taking cylinder 34 outward. Under the action of the air flow, the water located inside the L-shaped pipe 36 is pushed back into the river. Then, pulling up the pull ring plate 62 makes the slider 6 move upward. Under the clamping action of the pump suction drive assembly 4 and the disc 38, the disc 38 drives the piston head to move upward, and the sewage is pumped into the inside of the material taking cylinder 34 through the L-shaped pipe 36 by negative pressure suction for storage.

[0047] The remaining structures are the same as those in Embodiment 1.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
