[0032] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0033] Example 1

[0034] See also Figure 1 The present invention provides a portable sewage sampling device for environmental monitoring, comprising a suction device and a folding sampling device. The suction device is connected to the folding sampling device, which comprises a plurality of sequentially connected connecting rods, with adjacent connecting rods hingedly connected to each other. Each connecting rod has a slot provided therein, and a sampling tube is provided within the slot. The adjacent sampling tubes are connected by a hose. The suction device can optionally include a water pump, which is installed on the sampling pipe to provide sampling power for the folding sampling device.

[0035] In this embodiment, the two adjacent groups of connecting rods are rotatably connected by hinges. The angle between the two adjacent groups of connecting rods ranges from 0 to 180 degrees, and the hinges are located on both sides of the connecting rods, allowing each group of connecting rods to fold in an N-shape. A fixing device is provided between the two adjacent groups of connecting rods. When the angle between the two adjacent groups of connecting rods reaches 180 degrees, the fixing device 10 locks the connecting rods in place.

[0036] When sampling is required, each set of connecting rods is unfolded to form a long straight sampling pipe, and each set of connecting rods is locked and fixed by the fixing device 10. The end of the sampling pipe is placed below the water surface of the water area to be sampled, and the sampling tube in the sampling pipe is in contact with the water. The suction device is started to provide suction power, and the liquid to be tested in the water area to be sampled can be collected. After the collection is completed, the suction device is turned off, and the each set of connecting rods is folded and fixed to form a foldable sampling device, which does not take up too much space and is easy to carry.

[0037] Example 2

[0038] The main structure of this embodiment is the same as that of embodiment 1, except that this embodiment limits the structure of the fixing device 10 .

[0039] Specifically, refer to Figures 7-10 In this embodiment, the fixing device 10 includes a first fixing seat 1001, a second fixing seat 1002 and a fixing piece; the first fixing seat 1001 and the second fixing seat 1002 are respectively fixedly connected to two adjacent groups of connecting rods, and the first fixing seat 1001 and the second fixing seat 1002 are positioned correspondingly and are detachably fixedly connected by the fixing piece.

[0040] The fixing member includes a fixing pin 1003, a fixing rod 1004, a spring 1005, a limiting block 1006, and a fixing block 1007. A sliding groove adapted to the fixing pin 1003 is provided inside each of the first fixing seat 1001 and the second fixing seat 1002. The fixing pin 1003 is movably mounted within the sliding groove. The fixing block 1007 is fixedly mounted at the end of the second fixing seat 1002 away from the first fixing seat 1001. A limiting groove 1008 adapted to the size of the limiting block 1006 is defined within the fixing block 1007. A clamping groove 1009 adapted to the size of the limiting block 1006 is defined at the end of the fixing block 1007 away from the first fixing seat 1001. The limiting block 1006 is slidably mounted within the limiting groove 1008. The length of the limiting block 1006 is greater than the equivalent diameter of the fixing block 1007. The length of the clamping groove 1009 is less than the length of the limiting groove 1008.

[0041] One end of the fixing rod 1004 is fixedly connected to the fixing pin 1003, and the other end passes through the fixing block 1007 and is rotatably connected to the limiting block 1006. The spring 1005 is sleeved on the outside of the fixing rod 1004 and distributed between the fixing pin 1003 and the fixing block 1007. The diameter of the spring 1005 is smaller than the diameters of the fixing pin 1003 and the fixing block 1007. When the spring 1005 is not under force, the fixing pin 1003 is partially or completely located in the sliding groove of the first fixing seat 1001. When the limiting block 1006 moves along the limiting groove 1008 to the end of the fixing block 1007, rotates, and engages in the locking groove 1009, the fixing pin 1003 is separated from the first fixing seat 1001.

[0042] When the lock is released, the limit block 1006 is pulled to move outward along the limit slot 1008. The limit block 1006 pulls the fixing rod 1004 and the fixing pin 1003 away from the first fixing seat 1001 until the fixing pin 1003 is disengaged from the first fixing seat 1001. At this time, the spring 1005 is subjected to pressure and deformed. When the limit block 1006 continues to move to the end of the fixing block 1007, the limit block 1006 is rotated to be engaged in the slot 1009. At this time, the fixing pin 1003 and the first fixing seat 1001 are in a separated state, that is, the lock is released, and relative rotation can occur between the connecting rods. When locking is required, pull the limit block 1006 to move it outward along the slot 1009. When it moves to the end of the fixed block 1007, rotate the limit block 1006 to make it correspond to the position of the limit slot 1008. Under the action of the spring 1005, the limit block 1006 enters the limit slot 1008, driving the fixing rod 1004 and the fixing pin 1003 to move toward the first fixed seat 1001. Finally, the fixing pin 1003 enters the sliding groove of the first fixed seat 1001, the deformation of the spring 1005 disappears, and the locking is completed.

[0043] Example 3

[0044] The main structure of this embodiment is the same as that of embodiment 2, except that this embodiment limits the specific structure of the folding sampling device.

[0045] Specifically, refer to Figure 1 and Figures 3 to 6 In this embodiment, the folding sampling device includes a first connecting rod 2, a second connecting rod 4 and a third connecting rod 7 which are hinged in sequence. The first connecting rod 2, the second connecting rod 4 and the third connecting rod 7 are hinged in sequence through two sets of paging devices; a first card slot 3 is provided on the side of the first connecting rod 2, a fourth card slot 8 is provided on the side of the third connecting rod 7, and a second card slot 5 and a third card slot 6 are provided on the side of the second connecting rod 4; the first card slot 3 is connected to the second card slot 5 and is distributed on the same side of the connecting rod; the second card slot 5 and the third card slot 6 are connected to each other and are distributed on both sides of the second connecting rod 4; the fourth card slot 8 is connected to the third card slot 6 and is distributed on the same side of the connecting rod.

[0046] In this embodiment, sampling tubes are respectively disposed in the first, second, third, and fourth slots 3, 5, 6, and 8. The sampling tube in the first slot 3 is connected to the sampling tube in the second slot 5 via a hose, and the sampling tube in the fourth slot 8 is connected to the sampling tube in the third slot 6 via a hose. A Z-shaped channel is defined within the second connecting rod 4, with its ends communicating with the second and third slots 5, 6, respectively. The sampling tubes in the second and third slots 6 are interconnected via the Z-shaped channel. The first, second, third, and fourth slots 8 are all distributed along the length of the foldable sampling device.

[0047] In this embodiment, a sampling connector is provided at the sampling end of the folding sampling device, and the sampling connector is fixedly connected to the third connecting rod 7. A sampling port is provided on the sampling connector. The liquid to be tested enters the sampling connector through the sampling port, and then enters the sampling tubes of the third connecting rod 7, the second connecting rod 4 and the first connecting rod 2 in sequence, and finally the liquid to be tested is moved to the detection device for detection.

[0048] Example 4

[0049] The main structure of this embodiment is the same as that of embodiment 3, except that this embodiment is further provided with a portable detector 1 .

[0050] Specifically, refer to Figures 1-2 In this embodiment, the portable detector 1 is arranged at one end of the first connecting rod 2 and is detachably fixedly connected to the first connecting rod 2.

[0051] The portable detector 1 is internally provided with a composite sensor capable of testing water samples and a water sample detection box. The water sample detection box is connected to the sampling tube of the first connecting rod 2, and the water sample to be tested can enter the water sample detection box through a folding sampling device. The detection probe of the composite sensor is distributed in the water sample detection box and can detect the water sample in the water sample detection box (mainly involving the detection of hydrogen ion concentration, oxygen reduction potential, dissolved oxygen, and conductivity). At the same time, the water sample detection box is provided with a valve, through which the water sample can be discharged after the test is completed.

[0052] The working principle of this utility model is:

[0053] When water quality testing is required, the second connecting rod 4 is rotated to keep the second connecting rod 4 and the first connecting rod 2 in a straight line. The stopper 1006 is then manually pulled and rotated 90 degrees, allowing the stopper 1006 to disengage from the slot 1009 and engage into the stopper slot 1008. Under the reset action of the spring 1005, the stopper 1006, the fixing rod 1004, and the fixing pin 1003 are displaced, causing the fixing pin 1003 to move into the first fixing seat 1001, thereby fixing the first connecting rod 2 and the second connecting rod 4 to form a long rod. The third connecting rod 7 is then rotated, as described above, so that the second connecting rod 4 and the third connecting rod 7 are fixed to each other to form a long rod. Thus, the first connecting rod 2, the second connecting rod 4, and the third connecting rod 7 together form a long rod. The suction device and the portable detector 1 are then activated. When the portable detector 1 is in operation, it contacts the water source through the composite sensor to test the water quality.

[0054] The above are only preferred implementation methods of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications without departing from the principle of the present invention should be regarded as the protection scope of the present invention.
