[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only 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 creative efforts are within the scope of protection of the present invention.

[0032] See also Figures 1-6 , the present invention provides a technical solution:

[0033] A water quality testing sample collection device, comprising:

[0034] A protective housing 10, an operating assembly and a driving assembly, wherein the operating assembly is arranged at the bottom of the protective housing 10, and the driving assembly is arranged outside the protective housing 10;

[0035] The drive assembly includes two connecting plates 30, which are symmetrically mounted on the outside of the protective housing 10. A rectangular housing 31 is connected to the connecting plate 30, and a cylinder 33 is mounted inside the rectangular housing 31. The output end of the cylinder 33 is mounted with a U-shaped plate 34 via a floating joint. A linkage assembly is mounted on the protective housing 10, and an outer cover 32 is connected to the outside of the rectangular housing 31 via bolts.

[0036] Among them, the operating component is used for the user to control the electronic components of the collection device by operating the internal structure, and the driving component is used to drive the linkage component to rotate. Under the drive of the driving component, the linkage component forms a closed space in the protective shell 10, that is, to preserve the water quality sample.

[0037] like Figure 3-Figure 6 As shown, the linkage assembly is composed of: a disc 35, which is installed on the inner side of the U-shaped plate 34, and a plurality of external connection tubes 12 are arranged inside the protective shell 10 and pass through the disc 35, one end of the external connection tube 12 is hinged to the inner wall of the protective shell 10 through a bearing, and an inner connection rod 16 is fitted inside the external connection tube 12, and the inner connection rod 16 and the external connection tube 12 are located on the outer wall of the protective shell 10 and are connected to the linkage plate 11, an arc-shaped through groove 36 is opened on the disc 35, and the inner connection rod 16 and the external connection tube 12 are located at one end of the rectangular shell 31 and are installed with an L-shaped tube body 15, and the outside of the L-shaped tube body 15 is arranged in the arc-shaped through groove 36.

[0038] like Figure 3-Figure 6As shown, the principle of the linkage assembly is: the disc 35 is fixedly connected to the U-shaped plate 34, and an arc-shaped groove 36 is provided on the side of the disc 35 close to the U-shaped plate 34, so that when the disc 35 moves downward, it drives the two L-shaped tubes 15 to rotate inside the arc-shaped groove 36, and the L-shaped tubes 15 are respectively connected to the external connecting tube 12 and the internal connecting rod 16, and finally drives the linkage plate 11 connected to the external connecting tube 12 and the internal connecting rod 16 to rotate toward the inside of the protective shell 10.

[0039] Specifically, the plurality of external connection pipes 12 are integrally formed through the connecting plate.

[0040] As can be seen from the above, after multiple external connection tubes 12 are connected through the connecting plate, the linkage plate 11 is fixed to the external connection tube 12, so that when the internal connection rod 16 and the external connection tube 12 rotate, the integrally formed external connection tube 12 also drives the linkage plate 11 to rotate.

[0041] Specifically, the rectangular housing 31 has symmetrically formed sliding grooves 341 inside, the sliding grooves 341 are slidably connected to the sliding blocks 342 , and the outside of the sliding blocks 342 is connected to the U-shaped plate 34 .

[0042] As can be seen from the above, when the cylinder 33 drives the U-shaped plate 34 to move up and down, the U-shaped plate 34 drives the sliding block 342 to slide inside the sliding groove 341, giving the U-shaped plate 34 a limiting function.

[0043] like Figures 1-4 As shown, the operating assembly is composed of: a circular plate body 20, the circular plate body 20 is connected to the bottom of the protective shell 10, an operating compartment 26 is opened on the circular plate body 20, a controller 21 and a battery pack 22 are installed inside the operating compartment 26, and a lower cover plate 23 is installed on the circular plate body 20 by bolts.

[0044] like Figures 1-4 As shown, the principle of the operating component is: the controller 21 and the battery pack 22 are electrically connected to the ball level gauge 24 and the cylinder 33 through wires, the battery pack 22 provides electrical energy to the ball level gauge 24 and the cylinder 33, the controller 21 controls the start and stop of the ball level gauge 24 and the cylinder 33, and the lower cover 23 and the circular through hole 27 and the interior of the operating compartment 26 are waterproofed. The user can separate the lower cover 23 from the circular plate 20 by bolts, and then operate and replace the internal controller 21, ball level gauge 24 and battery pack 22.

[0045] Specifically, a circular through hole 27 is opened on the circular plate 20 , and a ball level gauge 24 is installed at the bottom of the protective shell 10 . One end of the ball level gauge 24 penetrates the bottom of the protective shell 10 and extends into the interior of the protective shell 10 .

[0046] As can be seen from the above, after the water source enters the interior of the protective shell 10, the ball liquid level gauge 24 causes the float to rise to a preset position according to the amount of water entering. The detection end of the ball liquid level gauge 24 is arranged inside the circular through hole 27 and does not contact the water source. The detection end passes through the middle of the bottom wall of the protective shell 10 and extends to the bottom of the external connecting pipe 12.

[0047] Specifically, a plurality of rope bodies 40 are arranged in an array outside the protective housing 10 , and one end of the rope body 40 away from the protective housing 10 is connected to an operating rope 41 through a connecting block.

[0048] As can be seen from the above, the number of rope bodies 40 is at least four, which are symmetrically arranged and connected to the outside of the protective shell 10 through fixed buckles. When the sampling device is in an upside-down position inside the river, the handheld operating rope 41 can be used to drive the four rope bodies 40 to flip the sampling device, and the water depth of the sampling device can be judged by the length of the operating rope 41 entering the water.

[0049] Specifically, a first counterweight 14 is installed on the outer wall of the protective shell 10 , and a second counterweight 25 is symmetrically installed inside the operating compartment 26 .

[0050] It can be seen from the above that during the sampling process, the setting of the first counterweight 14 can keep the sampling device in a relatively balanced state, and the weight of the first counterweight 14 is close to the total weight of the rectangular shell 31 and its internal structure. The two second counterweights 25 located inside the operating chamber 26 provide a stabilizing effect on the lower part of the sampling device, so that during the sampling process, the water inlet of the sampling device is always at the upper end.

[0051] Specifically, the interior of the protective housing 10 is connected to a water outlet pipe 13 , and a plug 17 is installed at one end of the water outlet pipe 13 .

[0052] As can be seen from the above, after the sampling device is taken out of the river and sent to the laboratory, the inspector opens the plug 17 to allow the water sample inside the protective shell 10 to flow out from the water outlet pipe 13.

[0053] Specifically, a sealing ring 18 is installed inside the protective housing 10 , and the sealing ring 18 is arranged on a side of the linkage plate 11 close to the rope body 40 .

[0054] As can be seen from the above, the sealing ring 18 installed on the inner wall of the protective shell 10 contacts the linkage plate 11 when the linkage plate 11 is parallel to the upper end of the protective shell 10, thereby preventing the water sample inside the protective shell 10 from flowing out.

[0055] The working steps of this solution are summarized and sorted out based on the above technical solution: First, the user drops the sampling device into the river through the operating rope 41. The two second counterweights 25 are provided to allow the sampling device to be immersed in the depth of the river. The user can determine the depth reached by the extended length of the operating rope 41;

[0056] The controller 21 controls the activation of the cylinder 33. The output end of the cylinder 33 drives the U-shaped plate 34 downward through the floating joint. The disc 35 is fixedly connected to the U-shaped plate 34. An arcuate through-slot 36 is formed on the side of the disc 35 close to the U-shaped plate 34. As the disc 35 moves downward, it drives the two L-shaped tubes 15 to rotate within the arcuate through-slot 36. The L-shaped tubes 15 are respectively connected to the outer connecting tube 12 and the inner connecting rod 16. Ultimately, the linkage plate 11 connected to the outer connecting tube 12 and the inner connecting rod 16 is driven to rotate toward the interior of the protective housing 10. The water source inside the river enters the interior of the protective housing 10 through the linkage plate 11.

[0057] After the water source enters the interior of the protective shell 10, the ball level gauge 24 detects the amount of water entering. After the float rises to a preset position, the controller 21 controls the start of the cylinder 33 again, so that it eventually drives the two linkage plates 11 to be parallel to the upper port of the protective shell 10, that is, the water sample is sealed inside the protective shell 10, and a sealing film is bonded to the side of the linkage plate 11 close to the bottom of the protective shell 10. The film is a rubber film. When the linkage plate 11 moves and rotates, the film is not displaced by the rotation of the linkage plate 11 and is in a compressed state. When the linkage plate 11 is parallel to the upper port of the protective shell 10, it is in an extended state, and the sealing ring 18 installed on the inner wall of the protective shell 10 contacts the linkage plate 11 when the linkage plate 11 is parallel to the upper port of the protective shell 10, thereby preventing the water sample inside the protective shell 10 from flowing out.

Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention.
