[0002] In a water treatment plant, in order to improve the water treatment efficiency, sometimes it is necessary to treat two or more kinds of water qualities simultaneously. To prevent chemical reactions from occurring between different water qualities and thus affecting the water treatment effect, before treating two or more kinds of water qualities, it is necessary to mix two water qualities and then take samples. After detecting the mixed water sample, it can be ensured that the treatment effect of the mixed water sample can the two water qualities be mixed and treated;

[0003] Traditional wastewater mixed sample sampling is generally isochronous mixed water samples. During collection, it is necessary to manually collect at equal time intervals, manually sample and divide the samples. The operation is time-consuming, and the divided sample volume is uneven. For this reason, we provide an automatic wastewater mixed sample collection device. Content of the Utility Model

[0008] Further, a sliding groove is formed in the inner wall of the limit box. A cover plate is in contact with the top of the rotating disk. A baffle is rotatably connected to the top of the cover plate. Fixing blocks are fixedly connected to both the left and right sides of the cover plate. The top of the collection box penetrates through the cover plate and extends to the outside. The bottom of the limit block is rotatably connected to a connecting rod, and the other end of the connecting rod is rotatably connected to a first sliding rod. A sliding rod is slidably connected to the inner wall of the first sliding rod. When a new collection box needs to be added, the baffle is opened and the new collection box is placed in the installation groove, without the need to open the cover plate again.

[0009] Further, the left and right sides of the sliding rod are fixedly connected to the left and right sides of the inner wall of the sliding groove. A first spring is sleeved on the outer surface of the sliding rod. The left side of the first spring is fixedly connected to the inner wall of the sliding groove, and the right side of the first spring is fixedly connected to the left side of the first sliding rod. The first spring rebounds to push the limit block upward to limit the rotating disk.

[0010] Further, an activity groove is formed inside the connecting shaft. There are two activity grooves in total, and the two activity grooves are symmetrically arranged with the connecting shaft as the center. The parts included in the two activity grooves are the same. A second spring is fixedly connected to the inner wall of the activity groove. The other end of the second spring is fixedly connected to a convex block. A groove is formed inside the rotating disk, and the outer surface of the convex block is adapted to the inner wall of the groove. Since the convex block is spherical and the connecting shaft rotates continuously, the convex block will be squeezed into the activity groove.

[0011] Further, the fixing mechanism includes fixing boxes fixedly connected to the left and right sides of the limit box. There are two fixing boxes in total, and the two fixing boxes are symmetrically arranged with the limit box as the center. The parts included in the two fixing boxes are the same. A push rod is slidably connected to the inside of the fixing box. An extrusion groove is formed inside the fixing box. The push rod is pushed to rotate the movable rod and at the same time push the movable rod to the right.

[0012] Further, the bottom of the push rod penetrates through the fixing box and extends to the outside. A push plate is fixedly connected to the bottom of the push rod. A movable rod is rotatably connected to the top of the push rod. An activity groove is formed inside the movable rod. A center rod is in contact with the inner wall of the activity groove. The front and back of the center rod are respectively fixedly connected to the front and back of the inner wall of the extrusion groove. Through the cooperation of the center rod and the activity groove, the movable rod can move to the right.

[0013] Further, the other end of the central rod is rotatably connected to a sliding block. A clamping block is slidably connected to the inner wall of the extrusion groove. A first sliding groove is formed inside the clamping block. The inner wall of the first sliding groove is slidably connected to the outer surface of the sliding block.

A clamping rod is in contact with the left side of the clamping block. The top of the clamping rod is fixedly connected to the bottom of the fixed block. When the clamping block moves to the right, the fixation of the clamping rod is cancelled, so that the cover plate can be removed. The operation is simple, and the cover plate can be quickly installed and disassembled.

[0014] The utility model has the following beneficial effects:

[0015] By arranging a limiting block in the utility model, when the sewage in the collection box reaches a certain level, the limiting block will be completely pushed into the limiting box. At this time, the limiting block will cancel the limitation on the rotating disc, so that the rotating disc can move. Then, the rotating disc is driven to rotate by the rotation of the connecting shaft. Then, the collection box that has completed the collection is pushed away by the rotation of the rotating disc, and a brand-new collection box is moved to the top of the limiting block. When the brand-new collection box reaches its top, due to the rebound of the first spring, the limiting block will be repositioned between the limiting box and the rotating disc, making the rotating disc unable to rotate anymore. There is no need to wait for a time interval. When one is full, it can be automatically switched to another one, and at the same time, the sub-sampling process is completed.

[0016] By arranging a movable rod in the utility model, when the push rod moves upward, it pushes the movable rod upward, and the movable rod will gradually move to the right. A central rod is arranged inside the movable rod. Therefore, when the push rod pushes the movable rod upward, the other end of the movable rod will move downward. The other end of the movable rod drives the sliding block to move downward along the first sliding groove, and pushes the clamping block to the right, while squeezing the third spring. When the clamping block moves to the right, the fixation of the clamping rod is cancelled, so that the cover plate can be removed. The operation is simple, and the cover plate can be quickly installed and disassembled.

[0027] Please refer to Figures 1-5 As shown, the present utility model is an automatic wastewater mixed sample collection device, including a collection mechanism 1 and a limit box 101. A fixing mechanism 2 is arranged on the outer surface of the collection mechanism 1. The top of the limit box 101 is in contact with a rotating disk 102. A motor 105 is fixedly connected inside the limit box 101. The top output end of the motor 105 is fixedly connected with a connecting shaft 106. The top of the connecting shaft 106 penetrates through the limit box 101 and extends into the rotating disk 102. Four installation grooves 120 are provided inside the rotating disk 102;

[0028] The four mounting grooves 120 are arranged in a circular array centered on the rotating disk 102. The parts contained inside the four mounting grooves 120 are the same. A collection box 113 is in contact with the inside of the mounting groove 120. A limiting block 107 is in contact with the bottom of the collection box 113. A clamping groove 119 is formed on the outer surface of the mounting groove 120. When the sewage inside the collection box 113 reaches a certain level, the limiting block 107 will be completely pushed into the limiting box 101. At this time, the limiting block 107 will cancel the limitation on the rotating disk 102, enabling the rotating disk 102 to move. Then, the connecting shaft 106 rotates to drive the rotating disk 102 to rotate. Then, the rotating disk 102 rotates to push away the collected collection box 113 that has been collected, and move a brand-new collection box 113 to the top of the limiting block 107. When the brand-new collection box 113 reaches its top, due to the rebound of the first spring 110, the limiting block 107 will be repositioned between the limiting box 101 and the rotating disk 102, making the rotating disk 102 unable to rotate any further. There is no need to wait for a time interval anymore. When one is full, it can automatically switch to another one, and at the same time, the sub-sampling process is completed.

[0029] A sliding groove 108 is formed on the inner wall of the limiting box 101. A cover plate 103 is in contact with the top of the rotating disk 102. A baffle 104 is rotatably connected to the top of the cover plate 103. Fixed blocks 118 are fixedly connected to both the left and right sides of the cover plate 103.

[0030] The top of the collection box 113 penetrates through the cover plate 103 and extends to the outside. The bottom of the limiting block 107 is rotatably connected to a connecting rod 112. The other end of the connecting rod 112 is rotatably connected to a first sliding rod 111. A sliding rod 109 is slidably connected to the inner wall of the first sliding rod 111.

[0031] The left and right sides of the sliding rod 109 are fixedly connected to the left and right sides of the inner wall of the sliding groove 108.

The left side of the first spring 110 is fixedly connected to the inner wall of the sliding groove 108, and the right side of the first spring 110 is fixedly connected to the left side of the first sliding rod 111.

[0032] An activity groove 116 is formed inside the connecting shaft 106. There are two activity grooves 116 in total, and the two activity grooves 116 are symmetrically arranged centered on the connecting shaft 106. The parts contained inside the two activity grooves 116 are the same. A second spring 117 is fixedly connected to the inner wall of the activity groove 116. The other end of the second spring 117 is fixedly connected to a convex block 114. A groove 115 is formed inside the rotating disk 102. The outer surface of the convex block 114 is adapted to the inner wall of the groove 115.

[0033] The fixing mechanism 2 includes fixing boxes 201 fixedly connected to the left and right sides of the limit box 101. There are two fixing boxes 201 in total, and the two fixing boxes 201 are symmetrically arranged with the limit box 101 as the center. The parts contained inside the two fixing boxes 201 are the same. A push rod 203 is slidably connected inside the fixing box 201, and an extrusion groove 204 is formed inside the fixing box 201.

[0034] The bottom of the push rod 203 penetrates through the fixing box 201 and extends to the outside. The bottom of the push rod 203 is fixedly connected to a push plate 202. The top of the push rod 203 is rotatably connected to a movable rod 205. An inner movable groove 206 is formed inside the movable rod 205. The inner wall of the inner movable groove 206 contacts a central rod 207. The front and back of the central rod 207 are respectively fixedly connected to the front and back inner walls of the extrusion groove 204. By moving the push rod 203 upward, the movable rod 205 is pushed upward, and the movable rod 205 will gradually move to the right. Since the central rod 207 is arranged on the inner wall of the movable rod 205, when the push rod 203 pushes the movable rod 205 upward, the other end of the movable rod 205 will move downward. The other end of the movable rod 205 drives a sliding block 210 to move downward along a first sliding groove 209, and the latch 208 is pushed to the right. At the same time, a third spring 211 is compressed. By moving the latch 208 to the right, the fixing of the latch rod 212 is cancelled, so that the cover plate 103 can be removed. The operation is simple, and the cover plate 103 can be quickly installed and disassembled.

[0035] The other end of the central rod 207 is rotatably connected to a sliding block 210. A latch 208 is slidably connected to the inner wall of the extrusion groove 204. A first sliding groove 209 is formed inside the latch 208. The outer surface of the sliding block 210 is slidably connected to the inner wall of the first sliding groove 209. The right side of the latch 208 is fixedly connected to a third spring 211. The right side of the third spring 211 is fixedly connected to the inner wall of the extrusion groove 204. The left side of the latch 208 contacts a latch rod 212. The top of the latch rod 212 is fixedly connected to the bottom of the fixed block 118.

[0036] A specific application of this embodiment is as follows: First, the staff places a certain number of collection boxes 113 into the installation groove 120, then covers the cover plate 103. While covering the cover plate 103, the fixed block 118 drives the clamping rod 212 to be inserted into the fixed box 201. Then, the device is placed at the collection location and the motor 105 is started. The motor 105 starts to drive the rotating disk 102 to rotate. Since the limiting block 107 is stuck between the limiting box 101 and the rotating disk 102 and pushes the collection box 113 upward. Because the convex block 114 is spherical and the connecting shaft 106 continues to rotate, the convex block 114 will be squeezed into the internal activity groove 116, thus leaving the groove 115 in the rotating disk 102. Therefore, the connecting shaft 106 can continue to rotate. When the device reaches the collection location, the wastewater will enter the collection box 113 and gradually push the collection box 113 downward. The downward movement of the collection box 113 drives the limiting block 107 to move downward. The downward movement of the limiting block 107 squeezes the connecting rod 112, causing the other end to move to the left and right, and pushing the first sliding rod 111 to squeeze the first spring 110. When the sewage in the collection box 113 reaches a certain level, the limiting block 107 will be completely pushed into the limiting box 101. At this time, the limiting block 107 will cancel the limitation on the rotating disk 102, enabling the rotating disk 102 to move. Then, the connecting shaft 106 rotates to drive the rotating disk 102 to rotate. Then, the rotating disk 102 rotates to push away the collection box 113 that has completed the collection, and moves a brand-new collection box 113 to the top of the limiting block 107. At the same time, after the collection box 113 filled with sewage is removed, the extrusion on the limiting block 107 will be cancelled. When the brand-new collection box 113 reaches its top, the first spring 110 rebounds to re-stick the limiting block 107 between the limiting box 101 and the rotating disk 102, making the rotating disk 102 unable to rotate anymore. After the collection is completed, the push plate 202 is pushed upward. The upward movement of the push plate 202 drives the push rod 203 to move upward. Then, through the upward movement of the push rod 203, the movable rod 205 is pushed upward, and the movable rod 205 will gradually move to the right. There is a central rod 207 inside the inner wall of the movable rod 205. So when the push rod 203 pushes the movable rod 205 upward, the other end of the movable rod 205 will move downward. The downward movement of the other end of the movable rod 205 drives the sliding block 210 to move downward along the first sliding groove 209 and pushes the clamping block 208 to the right, while squeezing the third spring 211. By moving the clamping block 208 to the right, the fixation on the clamping rod 212 is cancelled, enabling the cover plate 103 to be removed. After removing the cover plate 103, the collection box 113 located in the installation groove 120 is taken out through the clamping groove 119.
