DETAILED DESCRIPTION
[0028] Reference Figure 1-6A water body sampling device for water pollution control, comprising a sampling box 1 and a mounting platform 2, wherein the sampling box 1 is fixedly mounted on the mounting platform 2, and a sampling cylinder 3 and a material distribution cylinder 4 are respectively mounted on both sides of the bottom of the mounting platform 2, and the sampling cylinder 3 and the material distribution cylinder 4 are commonly connected with a connecting pipe 5;
[0029] A collecting assembly 6 for collecting sample water is provided in the sampling barrel 3, and the collecting assembly 6 is connected to the sampling box 1. The collecting assembly 6 includes an auger blade 61 rotatably connected to the sampling barrel 3, and the auger blade 61 is connected to a rotating shaft 1 62. The rotating shaft 1 62 passes through the inner wall of the mounting platform 2 and the sampling box 1 and is connected to a gear 1 63 in the part inside the sampling box 1. The gear 1 63 is meshed with a gear 2 64, and the gear 2 64 is connected to a driving motor 66 through a rotating shaft 2 65. The driving motor 66 is fixed to the outer top of the sampling box 1. The bottom of the piston 72 is fixedly connected to a traction rope 93, and the bottom of the traction rope 93 is connected to two branch ropes 94. The bottoms of the two branch ropes 94 are respectively connected to the ends of the shearing piece 912 away from the shearing head 911. A limiting sleeve 95 is provided at the connection between the traction rope 93 and the two branch ropes 94, and the limiting sleeve 95 is fixedly connected to the inner wall of the dividing barrel 4.
[0030] A dispensing assembly 7 is provided in the dispensing barrel 4, and the dispensing assembly 7 is used for first pumping the sampled water into the dispensing barrel 4 and then pressurizing and conveying it to the sampling box 1. After the sampled water is put into the dispensing barrel 4, the dispensing assembly 7 conveys the sampled water that enters the dispensing barrel 4 later to the sampling box 1, so as to ensure the accuracy of sampling. The dispensing assembly 7 includes an electric telescopic rod 71, and the electric telescopic rod 71 is installed on the inner wall of the dispensing barrel 4. The movable end of the electric telescopic rod 71 is fixedly connected with a piston 72, and the piston 72 is sealingly and slidably connected in the dispensing barrel 4. The top side of the dispensing barrel 4 is connected with an air outlet pipe 73, and the air outlet pipe 73 is sealed with an electromagnetic one-way valve. A feed port is commonly provided in the mounting table 2 and the sampling box 1, and the feed port is connected with an electromagnetic one-way valve.
[0031] The lower sides of the sampling barrel 3 and the material distribution barrel 4 are connected with a connecting platform 8, and a de-impurity component 9 is arranged in the connecting platform 8 to cut up algae and impurities in the water body to avoid clogging of the sampling barrel 3. The de-impurity component 9 includes a pair of scissors 91, and the scissors 91 include two shear heads 911 and two shear blades 912. A shear head 911 and a shear blade 912 form a knife body part, and the two knife body parts are rotatably connected by a connecting shaft 92. The two shear blades 912 are symmetrically arranged at the bottom of the sampling barrel 3. The connecting shaft 92 is fixedly connected to the bottom of the connecting platform 8. The bottom of the piston 72 is fixedly connected to a traction rope 93, and the bottom of the traction rope 93 is connected to two dividing ropes 94. The bottoms of the two branch ropes 94 are respectively connected to the ends of the shearing blades 912 away from the shearing head 911. A limiting sleeve 95 is provided at the connection between the traction rope 93 and the two branch ropes 94. The limiting sleeve 95 is fixedly connected to the inner wall of the material distribution barrel 4. The limiting sleeve 95 is used to limit the angle between the two branch ropes 94, so that when the traction rope 93 is pulled to move upward, the two branch ropes 94 will gradually approach each other, thereby driving the two shearing blades 912 to rotate and realize the shearing effect. The piston 72 moves back and forth under the action of the electric telescopic rod 71, so it can drive the traction rope 93 and the two branch ropes to move back and forth, thereby realizing the repeated work of the scissors 91.
[0032] The sampling barrel 3 and the distributing barrel 4 are slidably connected to a fixed platform 10, and the fixed platform 10 is connected to an adjustment component 11 for adjusting the height of the sampling barrel 3. The adjustment component 11 includes a threaded sleeve 111 arranged on the outside of the sampling barrel 3, and the threaded sleeve 111 is threadedly connected to an outer ring 112. The outer ring 112 is fixedly connected to a mounting groove provided in the fixed platform 10. The threaded sleeve 111 can be driven to translate up and down by rotating the outer ring 112, so as to adjust the working height of the impurity removal component 9 and the collection component 6. The outer side of the outer ring 112 is sleeved with a gear three 113, and the gear three 113 is meshed with a gear four 114. The gear four 114 is connected to the rotating shaft two 65. The side of the fixed platform 10 is connected to an adjustment shaft 12, and the adjustment shaft 12 is connected to an external reversing motor.
[0033] When the present invention is in use, the position of the connecting platform 8 is adjusted by adjusting the shaft 12 and the reversing motor. When the connecting platform 8 is located at the bottom, it is in the sampling state. The actual height of the connecting platform 8 can be adjusted by the adjusting component 11 on the fixed platform 10, wherein the bottom of the sampling tube 3 is the sampling height, which is flush with the bottom of the connecting platform 8. Therefore, when the bottom of the connecting platform 8 is located on the water surface, the collecting component 6 realizes the sampling work of the surface water. When the bottom of the connecting platform 8 is immersed in the water, the collecting component 6 realizes the sampling work of the deep water.
[0034] During the sampling operation, the auger blade 61 in the sampling tube is driven and transmitted by the rotating shaft 1 62, gear 1 63, gear 2 64, rotating shaft 2 65 and driving motor 66 to realize the process of conveying the water at the bottom of the connecting platform 8 upward, and in this process, the electric telescopic rod 71 outputs intermittent telescopic work, and the solenoid valve connected to the air outlet pipe 73 is in an open state, so that the piston 72 connected to the movable end of the electric telescopic rod 71 will continuously pressurize the distributing tube 4 and the sampling tube 3 whose space is gradually reduced, so that the internal air is discharged through the air outlet pipe 73, and after the sampled water completely enters the distributing tube 4, the solenoid valve connected to the air outlet pipe 73 is closed and the solenoid valve in the feed port is opened. At this time, the sample water that first enters the sampling tube 3 is discharged. The sample water enters the bottom of the dividing barrel 4, and the sample water that enters the sampling barrel 3 later enters the top of the dividing barrel 4, and the piston 72 moves upward again to input the sample water that enters the sampling barrel 3 later into the sampling box 1. The advantage of this is that the sample water that first enters the sampling barrel 3 contains a large amount of impurities, and its water quality is somewhat different from the average water quality at the corresponding height. There is a problem of inaccuracy in sampling these waters as samples, and the solid impurities cut into pieces by the impurity removal component 9 will also enter the sampling barrel 3 first, causing the problem of more sampling impurities. Through the setting of the dividing barrel 4 in the present invention, the water that enters the sampling barrel 3 later is transported to the sampling box 1 as sample water for storage, which can improve the accuracy of sampling and avoid interference from other factors.
[0035] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
