Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] During specific implementation: as Figures 1-5 shown, a multi-point synchronous river water quality sampling device includes:

[0026] A cross bar 100, a sampling cylinder 200 and a slide rail component 400. The middle sampling cylinder 200 is fixedly connected to one end of the cross bar 100. A piston rod 300 is arranged in the sampling cylinder 200. The slide rail component 400 is arranged between two adjacent piston rods 300;

[0027] An operating mechanism 500. The operating mechanism 500 includes a three-way pipe 510 and a cylinder 530 arranged on the cross bar 100. A piston plate 540 is arranged in the cylinder 530. The top end of the piston plate 540 is fixedly connected with a connecting rod 541. The other end of the connecting rod 541 penetrates through the cylinder 530 and is connected to the middle piston rod 300. An air bag 550 is arranged between two adjacent sampling cylinders 200. A connecting pipe 551 is arranged between two adjacent air bags 550. An electric three-way valve 511 is arranged on the three-way pipe 510. The two ends of the three-way pipe 510 are respectively communicated with the cylinder 530 and the middle air bag 550. The remaining end of the three-way pipe 510 is provided with a latex ball 520.

[0028] As Figure 1 and Figure 2 shown, the other end of the cross bar 100 is plugged with an extension rod 110. The top end of the extension rod 110 is provided with uniformly distributed round holes 120. The top end of the cross bar 100 is provided with a bolt 130. The end of the bolt 130 penetrates through the cross bar 100 and extends into the round hole 120. When the overall length of the device needs to be adjusted, pull the extension rod 110. After adjusting it to the required length, use the bolt 130 and the round hole 120 to complete the adjustment of their lengths.

[0029] The other end of the extension rod 110 is fixedly connected with a handle 140. The surface of the handle 140 is provided with uniformly distributed grooves, which is more convenient for operating the device.

[0030] The surface of the handle 140 is fixedly connected with a buckle, and the three-way pipe 510 is clamped with the buckle, which serves the purpose of limiting the three-way pipe 510 and is convenient for its storage.

[0031] As Figure 3 and Figure 4 shown, an air pipe is arranged on the surface of the latex ball 520, and a switch 521 is arranged on the air pipe. When the device is reset, the switch 521 can be used to discharge the gas in the air bag 550 and the cylinder 530, realizing the reset operation of the device. After resetting, the volume can be reduced, which is more convenient for storage and transportation.

[0032] A limiting ring is fixedly connected inside the cylinder 530, and the top end of the limiting ring is in close contact with the piston plate 540. The limiting ring can limit the position of the piston plate 540.

[0033] As Figure 1 and Figure 5 shown, the upper end of the surface of the sampling cylinder 200 is fixedly connected with a mounting plate, and a magnet 210 is fixedly connected to the bottom end of the mounting plate. When storing the device, the sampling cylinders 200 close to each other have better stability under the adsorption of the magnet 210 and are not prone to separation.

[0034] Two rings 220 are fixedly connected to the bottom end of one mounting plate, and a positioning rod 230 matched with the rings 220 is fixedly connected to the bottom end of the other mounting plate. When the adjacent sampling cylinders 200 approach, the positioning rod 230 will be inserted into the corresponding ring 220, cooperating with the magnet 210 to improve the stability when the adjacent sampling cylinders 200 are connected.

[0035] Working principle: When arriving at the river to be sampled, first adjust the length between the extension rod 110 and the cross bar 100 by using the round hole 120 and the bolt 130. Then, repeatedly squeeze the latex ball 520. Under the action of the electric three-way valve 511, the gas will be directly injected into the airbag 550. The airbag 550 expands, and the two adjacent sampling cylinders 200 will move away from each other. The slide rail component 400 plays a role in limiting it. Until the deformation is completed, the operator uses the grip 140 to move the sampling cylinder 200 to a suitable sampling position in the river. The airbag 550 can play a role in floating. Use the electric three-way valve 511 to switch, and then repeatedly squeeze the latex ball 520, so that the gas can directly enter the cylinder 530. The gas squeezes the piston plate 540, thereby driving the connecting rod 541 to move upward synchronously. Under the connection action of multiple slide rail components 400, multiple piston rods 300 will move upward synchronously. Use the sampling cylinder 200 to complete the sampling operation. The operation of the sampling cylinder 200 and the piston rod 300 is similar to the principle of a syringe. At the same time, in the appendix Figure 5 It can be clearly seen that the slider between the two slide rail components 400 is T-shaped. Therefore, the slide rail component 400 can play a role in guiding and connecting the adjacent piston rods 300. After the sampling is completed, move the device to the shore and reset it.

[0036] It should be noted that in the above description, the magnet 210, the slide rail component 400, the electric three-way valve 511, the latex ball 520, the switch 521, etc. are all devices with relatively mature applications in the prior art. The specific models can be selected according to actual needs. At the same time, the power supply of the electric three-way valve 511 can be powered by an internal power supply or by mains power. The specific power supply method is selected according to the situation. Among them, the slide rail component 400 is composed of the appendix Figure 5 It can be clearly seen that it is divided into a slide rail and a slide rod part, which are relatively mature components in the prior art. And the latex ball 520 is mostly used in blood pressure measurement devices, so it is not described in detail here and will not be elaborated.

[0037] In addition, it should be understood that although this specification is described according to the embodiments, not each embodiment only contains an independent technical solution. This narrative method of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
