Description

Technical Field

[0001] The invention relates to the field of water body sampling, in particular to a water body fixed-depth sampler. Background Art

[0002] Water quality sampling is mainly to sample water bodies at different depths. The traditional sampling equipment is a "card-capped water quality sampler". When it reaches a specific position, it starts the trigger switch to lock (collect) the water body at the current water level. However, multiple "card-capped water quality samplers" will be installed for a single collection, so that water bodies at different depths and positions can be collected at one time. However, the existing technology needs to control active triggering at different depths and bind multiple "card-capped water quality samplers", which requires a large bracket. The equipment is bulky as a whole and difficult to transport. Each "card-capped water quality sampler" also needs to be installed separately, which is very inconvenient and the equipment is very complicated.

[0003] To this end, we propose a water constant depth sampler to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to provide a water constant depth sampler to solve the problems raised in the above-mentioned background technology. The technical solution of the present invention aims at the technical problem that the existing technical solution is too single, and provides a solution that is significantly different from the existing technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A water constant depth sampler comprises a chamber, a one-way shaft is installed at the axial end of the chamber, a partition plate is installed on the outer wall of the one-way shaft, an elastic arc sheet is installed on the inner side of the chamber, a rubber piston is installed in the middle of the elastic arc sheet, a water inlet pipe is installed on one side of the chamber, a baffle rod is installed on the end face of the one-way shaft, a limit frame is installed on the outer wall of the baffle rod, a placement shaft is arranged inside the limit frame, a weight is connected to the inner side of the placement shaft, a slide rod is installed on one side of the limit frame, and a diaphragm is installed on one end of the slide rod.

[0007] In a further embodiment, a counterweight is installed at the outer bottom of the chamber, and the counterweight and the limit frame are fixedly connected to each other.

[0008] In a further embodiment, the partition plates are evenly distributed around the inside of the one-way shaft, and the partition plates are tightly fitted to the inner wall of the chamber.

[0009] In a further embodiment, the elastic arc sheet and the chamber are both distributed at one end of the outer wall of the chamber away from the counterweight, and the rubber piston and the water inlet pipe correspond to each other.

[0010] In a further embodiment, the placement shaft and the axial ends of the one-way shaft are fixedly connected to each other, and the placement shaft is movably connected to the weight through a slot.

[0011] In a further embodiment, the bottom of the limit frame is slidably connected to the slide rod through a groove, the middle of the diaphragm is connected to the slide rod, and the edge is connected to the limit frame.

[0012] In a further embodiment, a traction rope is connected to the outside of the chamber.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The sampling personnel of the present invention can sample water bodies at different depths, and when operating, the workers only need to put the device directly into the water. The sampling device can automatically sample water at different depths and can be fully customized. Through the one-way shaft and the partition plate, the partition plates filled with water can naturally rotate downward, thereby realizing the method of sequential water intake. The present invention also sets weights of different masses. Since the water level pressures at different depths are different, the structure can only lift the weights when a specific depth is reached, and can continue to rotate after the weights are lifted to complete the water intake operation. The weight of the weights can be defined artificially and autonomously, and the weight of the weights is defined according to different depths and different pressures to collect water sources at a specific depth, and can achieve automatic sealing after the collection is completed, and there will be no leakage and other problems.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0031] Example 1: Please refer to Figure 1-11 In an embodiment of the present invention, a water fixed depth sampler includes a chamber 1, a one-way shaft 3 is installed at the axial end of the chamber 1, a partition plate 4 is installed on the outer wall of the one-way shaft 3, an elastic arc sheet 5 is installed on the inner side of the chamber 1, a rubber piston 6 is installed in the middle of the elastic arc sheet 5, a water inlet pipe 7 is installed on one side of the chamber 1, a baffle rod 8 is installed on the end face of the one-way shaft 3, a limit frame 9 is installed on the outer wall of the baffle rod 8, a placement shaft 10 is arranged inside the limit frame 9, a weight 11 is connected to the inner side of the placement shaft 10, a slide rod 13 is installed on one side of the limit frame 9, a diaphragm 12 is installed on one end of the slide rod 13, a counterweight 2 is installed on the outer bottom of the chamber 1, the counterweight 2 and the limit frame 9 are fixedly connected to each other, and the counterweight 2 at the bottom of the chamber 1 can ensure that the chamber 1 will not rotate arbitrarily after entering the water, and always keep the water inlet pipe 7 in a continuously descending state upward.

[0032] The bottom of the limit frame 9 is slidably connected to the slide rod 13 through a groove, the middle of the diaphragm 12 is connected to the slide rod 13, and the edge is connected to the limit frame 9. The diaphragm 12 is an inelastic structure, and its main function is to isolate the water body. The slide rod 13 is a "T"-shaped structure as a whole to prevent the slide rod 13 from being completely pushed into the interior under the action of water pressure.

[0033] The outer side of the chamber 1 is connected with a traction rope, which is used to restrain the device after entering the water, so that it is convenient to pull it up through the traction rope after the sampling is completed.

[0034] Example 2: Please refer to Figure 1-11 , which is different from Example 1, is that the partition plates 4 are evenly distributed around the unidirectional shaft 3, the partition plates 4 are tightly fitted with the inner wall of the chamber 1, and the partition plates 4 can separate water of different depths. The partition plates 4 need to fit with the inner wall of the chamber 1 to avoid mixing of water of different depths.

[0035] The placement shaft 10 is fixedly connected to the shaft end of the one-way shaft 3, and the placement shaft 10 is movably connected to the weight 11 through a slot. The placement shaft 10 is mainly used to place weights 11 of various different weights, and as it rotates, the weight of the falling weights 11 increases sequentially, and the placement shaft 10 needs to rotate with the one-way shaft 3.

[0036] Example 3: Please refer to Figure 1-11, which is different from Example 1 in that: the elastic arc piece 5 and the chamber 1 are both distributed at the end of the outer wall of the chamber 1 away from the counterweight 2, the rubber piston 6 and the water inlet pipe 7 correspond to each other, and the elastic arc piece 5 can seal the position of the water inlet pipe 7. When external water flows in, the elastic arc piece 5 can be pushed downward to achieve rapid water inlet. When the partition plate 4 rotates and contacts with the elastic arc piece 5, the elastic arc piece 5 will be pressed upward, thereby sealing the water inlet pipe 7 to prevent continuous water inflow.

[0037] The working principle of the present invention is:

[0038] First, the tester puts the device into the water with the weight 2 facing downward. When the water enters the water, Figure 1 Water will enter the middle Z first. During the process of water entering, due to the impact force, the elastic arc piece 5 will be forced to press downward, and the rubber piston 6 will be separated from the inside of the water inlet pipe 7. Due to the bending effect of the elastic arc piece 5, although a lot of water enters the Z, the bending effect prevents the one-way shaft 3 and the partition plate 4 from continuing to rotate. When the water body is almost full, the internal and external pressures are almost the same, causing the elastic arc piece 5 to fit into the groove of the chamber 1, so that the partition plate 4 continues to rotate.

[0039] After rotation Figure 3 He Ru Figure 8 After the rotation, the weight 11 will fall down, pressing the diaphragm 12 and the slide bar 13, so that the slide bar 13 can contact with the stop bar 8, causing the one-way shaft 3 to be unable to continue rotating. When the water pressure reaches the weight that matches the weight 11, the weight 11 will be pushed up. Fig. 9 , push the weight 11 into the interior of the placement shaft 10, and then the partition plate 4, the one-way shaft 3, and the placement shaft 10 continue to rotate until Figure 5 position, and continue to let in water, and simultaneously push the elastic arc piece 5 outwards. When water starts to flow in, the partition plate 4 cannot continue to rotate due to the bending of the elastic arc piece 5;

[0040] When the water filling is completed, the partition plate 4, the one-way shaft 3, and the placement shaft 10 continue to rotate, and the subsequent weights 11 continue to fall, and the weight of the weights 11 gradually increases, thereby completing the function of taking water at different depths. The limit frame 9 can be made into a detachable design, and the user can place weights 11 of different weights inside, thereby achieving the operation of filling water at different depths. When all depths are filled with water, the device is pulled up by the rope;

[0041] When pouring water outward, the rotation position of the one-way shaft 3 can be manually controlled, and the rod is inserted into the inside of the water inlet pipe 7 to push open the elastic arc sheet 5 to let the water flow out naturally. Note that the elastic arc sheet 5 will only block the pipe opening of the water inlet pipe 7, and there will be no problem of upper and lower separation in the space;

[0042] The reason why the partition plate 4 and the one-way shaft 3 rotate is that when water is stored in a certain space, there is no water but air in other spaces, so the one-way shaft 3 and the partition plate 4 will rotate, and the one-way shaft 3 will only rotate on one side.

[0043] Figures 2 to 6 It is a cyclic process of the entire operation. In the figure, Z represents the space where water initially enters, and m represents one of the weights 11, which is convenient for understanding.

[0044] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0045] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
