Description

Technical Field

[0001] The present application belongs to the technical field of sampling devices, and specifically relates to an explosion-proof and rupture-proof sampling bottle. Background Art

[0002] Domestic and industrial wastewater pollutes waterways because industrial wastewater (or domestic wastewater) contains large amounts of organic matter. The oxidative decomposition of these organic substances consumes significant amounts of dissolved oxygen in the water, disrupting the oxygen balance within the water. Furthermore, due to the complex and diverse nature of organic matter in water, it's impossible to monitor each of these substances individually. Consequently, researchers in this field measure the degree of water pollution by measuring the amount of dissolved oxygen consumed by organic matter under certain conditions. This includes indicators such as biochemical oxygen demand (BOD) and chemical oxygen demand (COD).

[0003] At present, the sampling device used to monitor indicators such as biochemical oxygen demand and chemical oxygen demand in industrial wastewater usually consists of a sampler, an explosion-proof and rupture-proof sampling bottle, a stainless steel hook and a sampling rope. Although the above-mentioned sampling device is simple and easy to use, it has defects such as the long contact time between the sampled liquid and the air and poor air tightness of the sampling device.

[0004] Based on this, there is an urgent need to provide an explosion-proof and rupture-proof sampling bottle to solve the above-mentioned technical problems. Summary of the Invention

[0005] In response to the above problems, the present application provides an explosion-proof and rupture-proof sampling bottle, which can shorten the contact time between the sampled liquid and the air while ensuring the airtightness of the explosion-proof and rupture-proof sampling bottle.

[0006] To achieve the purpose of this application, this application provides the following technical solutions:

[0007] In a first aspect, the present application provides an explosion-proof and rupture-proof sampling bottle, which includes a shell, a head portion having a liquid outlet, and an outer wall surface of which is sequentially formed with a first groove structure and a second groove structure along the height direction of the shell;

[0008] a plug capable of closing the liquid outlet;

[0009] The bottle cap comprises a bottle cap body having a hollow portion and a first hook portion and a second hook portion respectively extending downward from two sides of the bottle cap body;

[0010] In which, the plug is assembled on the bottle cap body; the first hook portion and the second hook portion are both fastened to the first groove structure or the second groove structure, and when the first hook portion and the second hook portion are switched from the first groove structure to the second groove structure, the plug is sealed with the opening of the liquid outlet.

[0011] In a possible implementation, the housing has a receiving cavity, and the bottom of the housing is bent upward and extended to form a liquid inlet channel connected to the receiving cavity and having a liquid inlet formed at a rear end;

[0012] The explosion-proof and rupture-proof sampling bottle also includes a movable component that presses against the opening of the liquid inlet, and the movable component is separated from the opening of the liquid inlet under the push of the liquid to be sampled, so that the liquid to be sampled flows from the liquid inlet channel into the accommodating cavity.

[0013] In a possible implementation, the movable assembly includes a movable cover plate and an auxiliary structure fixed to the inner bottom of the shell, and the inner wall of the auxiliary structure and the tail of the liquid inlet channel are enclosed to form a limited space;

[0014] When the movable cover is pushed by the liquid to be sampled, the auxiliary structure resists the movable cover so that the movable cover moves in the limiting space in a direction close to the auxiliary structure.

[0015] In a possible implementation, the bottle cap body includes an edge portion, a connecting portion looped within the edge portion, and a plurality of separators, and both ends of each separator are respectively fixed to the edge portion and the connecting portion.

[0016] In a possible implementation, along the circumference of the bottle cap body, the included angle between each two adjacent partitions is a preset angle, and the values of each two adjacent preset angles are equal.

[0017] In a possible implementation, a sealing member is disposed at the opening of the liquid inlet.

[0018] In a possible implementation, it further includes: a counterweight, and the counterweight is sleeved on the outer wall of the shell and facilitates the sinking of the explosion-proof and rupture-proof sampling bottle into the water area to be sampled.

[0019] In a possible implementation, the device further includes: a handle;

[0020] The outer wall surface of the shell is correspondingly provided with mounting holes, and the two ends of the handle are rotatably inserted into the corresponding mounting holes so that the handle is assembled on the shell.

[0021] In a possible implementation, the housing further includes an inner liner body and an outer shell sleeved outside the inner liner body;

[0022] Wherein, the material of the inner container body is glass material.

[0023] In a possible implementation, the shell and the bottle cap are both made of PVC, OPP, PI or PET.

[0024] Beneficial effect: By providing a first groove structure and a second groove structure on the outer wall of the shell, and forming a first hook portion and a second hook portion on the bottle cap body for buckling the first groove structure or the second groove structure, when the first hook portion and the second hook portion switch from the first groove structure to the second groove structure, the plug and the opening of the liquid outlet are sealed and matched. In the above process, while ensuring the airtightness of the explosion-proof and rupture-proof sampling bottle, the user's hand has no contact with the plug, and only needs to adjust the matching position of the bottle cap on the shell, omitting the step of embedding the plug into the liquid outlet opening, thereby shortening the contact time between the sampled liquid and the air, and thereby reducing the risk of contamination of the sampled liquid.

[0033] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0034] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the technical features indicated. Thus, features specified as "first" or "second" may explicitly or implicitly include one or more of such features; and in the description of this application, unless otherwise specified, "plurality" means two or more.

[0035] refer to Figure 1 This application provides an explosion-proof and rupture-proof sampling bottle for measuring the values of multiple indicators such as biochemical oxygen demand and chemical oxygen demand in domestic sewage to determine the degree of pollution in the water area to be sampled. Of course, the explosion-proof and rupture-proof sampling bottle is not limited to the aforementioned application scenarios.

[0036] The explosion-proof and rupture-proof sampling bottle 1 includes a shell 10, a plug 11 and a bottle cap 12. The plug 11 is embedded in the shell 10, and the bottle cap 12 is connected to the plug 11 and fixed to the shell 10 by the bottle cap 12 to achieve the sealing of the explosion-proof and rupture-proof sampling bottle 1.

[0037] The housing 10 has a liquid outlet 102 at its head for transferring the sampled liquid. Obviously, the plug 11 is embedded in the opening of the liquid outlet 102, or in other words, the plug 11 can close the liquid outlet 102 to achieve relative sealing of the explosion-proof and rupture-proof sampling bottle 1.

[0038] Combine Figure 1 , while referring to Figure 2The bottle cap 12 includes a bottle cap body having a hollow area, and a first hook portion 121 and a second hook portion 122 extending downward from both sides of the bottle cap body. Correspondingly, a first groove structure 1000 and a second groove structure 1001 are sequentially formed on the outer wall surface of the shell 10 along the height direction of the shell 10, and the first hook portion 121 and the second hook portion 122 are both fastened to the first groove structure 1000 or the second groove structure 1001. In order to facilitate the description and understanding of the first groove structure 1000 and the second groove structure 1001, the position where the first hook portion 121 and the second hook portion 122 are fastened to the first groove structure 1000 is defined as the first position, and the position where the first hook portion 121 and the second hook portion 122 are fastened to the second groove structure 1001 is defined as the second position. It is understandable that when the first hook portion 121 and the second hook portion 122 are in the first position, the plug 11 is separated from the opening of the liquid outlet 102, and a gap is left between the bottom of the plug 11 and the opening of the liquid outlet 102 to facilitate the flow of air. In addition, referring to the above, there is a hollow area on the bottle cap body. At this time, the explosion-proof and rupture-proof sampling bottle 1 has the function of air exchange, so that the liquid to be sampled can flow into the explosion-proof and rupture-proof sampling bottle 1 during the sampling process. It should be noted that in order to avoid contaminating the water sample, that is, to minimize the contact between the user's hand and the plug 11, the plug 11 is assembled to the bottle cap body.

[0039] When the first hook portion 121 and the second hook portion 122 are in the second position, the plug is tightly embedded in the opening of the liquid outlet 102 to achieve relative sealing of the explosion-proof and rupture-proof sampling bottle 1. Obviously, when the first hook portion 121 and the second hook portion 122 are switched from the second position to the first position, in other words, on the one hand, when the first hook portion 121 and the second hook portion 122 are switched from the second groove structure 1001 to the first groove structure 1000, the plug 11 is disengaged and a gap is created between the plug and the opening of the liquid outlet 102, so that the liquid to be sampled can flow into the explosion-proof and rupture-proof sampling bottle 1 during the sampling process, and it is also convenient to transfer the sampled liquid. On the other hand, when the first hook portion 121 and the second hook portion 122 are switched from the first groove structure 1000 to the second groove structure 1001, the plug 11 is sealed with the opening of the liquid outlet 102 to ensure the airtightness of the explosion-proof and rupture-proof sampling bottle 1.

[0040] It should also be noted that in this embodiment, the first groove structure 1000 is close to the opening of the liquid outlet 102, while the second groove structure 1001 is far from the opening of the liquid outlet 102. In other embodiments, the positions of the first groove structure 1000 and the second groove structure 1001 are not limited.

[0041] In one embodiment, the first groove structure 1000 may include two symmetrically arranged first grooves. When the first hook portion 121 and the second hook portion 122 are fastened to the first groove structure 1000, the first hook portion 121 and the second hook portion 122 are respectively embedded in the groove body of the corresponding first groove. The second groove structure 1001 may include two symmetrically arranged second grooves. When the first hook portion 121 and the second hook portion 122 are fastened to the second groove structure 1001, the first hook portion 121 and the second hook portion 122 are respectively embedded in the groove body of the corresponding second groove. Of course, in other embodiments, the first groove structure 1000 and the second groove structure 1001 may also have other structures.

[0042] Optionally, the bottom of the plug 11 can be processed into a spiral structure to reduce or even eliminate foam in the collected liquid (or water sample). Of course, in other specific embodiments, the bottom of the plug 11 can also be processed into a spiral structure, as long as the structure can eliminate foam in the collected liquid.

[0043] In one embodiment, the housing 10 has a receiving chamber 1010. To facilitate the flow of the liquid to be sampled into the explosion-proof and rupture-proof sampling bottle 1, the bottom of the housing 10 bends upward and extends to form a liquid inlet channel 1002 that is connected to the receiving chamber 1010 and has a liquid inlet port 103 at its tail end. In addition, to ensure that the explosion-proof and rupture-proof sampling bottle 1 remains sealed when not in use, while allowing the liquid to be sampled to flow into the explosion-proof and rupture-proof sampling bottle 1 when in use, the explosion-proof and rupture-proof sampling bottle 1 also includes a movable component 13 that presses against the opening of the liquid inlet port 103. Under the buoyancy of the liquid to be sampled, the movable component 13 disengages from the opening of the liquid inlet port 103, allowing the liquid to be sampled to flow from the liquid inlet channel 1002 into the receiving chamber 1010.

[0044] Specifically, the movable assembly 13 includes a movable cover plate 130 and an auxiliary structure 131 fixed to the inner bottom of the housing 10. The inner wall of the auxiliary structure 131 and the rear end of the liquid inlet channel 1002 enclose a confined space. When the movable cover plate 130 is pushed by the liquid to be sampled, the auxiliary structure 131 resists the movable cover plate 130, allowing the movable cover plate 130 to move within the confined space in a direction closer to the auxiliary structure 131. For example, the auxiliary structure 131 can be a three-legged fixing pin.

[0045] In one embodiment, reference Figure 3Because the bottle cap body has a hollowed-out area, and to form the aforementioned hollowed-out area, the bottle cap body includes a rim portion 1200, a connecting portion 1201 trapped within the rim portion 1200, and a plurality of separators 1202. The two ends of each separator 1202 are respectively fixed to the rim portion 1200 and the connecting portion 1201. It should be noted that the rim portion 1200 can be annular in shape, and the connecting portion 1201 can be circular in shape. Of course, in other specific embodiments, the shapes of the rim portion 1200 and the connecting portion 1201 are not limited.

[0046] Alternatively, as Figure 4 As shown, the bottom surface of the connecting portion 1201 is provided with a polygonal groove, and correspondingly, the cross-section of the head of the plug 11 is polygonal, so that the plug 11 can be embedded and connected to the bottle cap body. Of course, in other specific embodiments, the plug 11 and the connecting portion 1201 can also be connected in other ways.

[0047] It should also be noted that in order to achieve uniform arrangement of the partitions 1202 along the circumference of the bottle cap body, the angle between each two adjacent partitions 1202 along the circumference of the bottle cap body is a preset angle, and the values of each two adjacent preset angles are equal.

[0048] Optionally, to further ensure that the movable cover 130 fits tightly with the opening of the liquid inlet 103, or to further improve the sealing performance of the explosion-proof and rupture-proof sampling bottle 1 when not in use, a sealing member 14 is provided at the opening of the liquid inlet 103. For example, the sealing member 14 may be a sealing ring.

[0049] Optionally, in order to enable the explosion-proof and rupture-proof sampling bottle 1 to sink quickly into the water area to be sampled, the explosion-proof and rupture-proof sampling bottle 1 also includes a counterweight 15, and the counterweight 15 is sleeved on the outer wall of the shell 10.

[0050] Optionally, to facilitate immersion or extraction of the explosion-proof and rupture-resistant sampling bottle 1 into or from the waters to be sampled, the explosion-proof and rupture-resistant sampling bottle 1 further includes a handle. To facilitate mounting the handle to the housing 10, mounting holes 1003 are correspondingly defined on the outer wall of the housing 10, and the two ends of the handle are rotatably inserted into the corresponding mounting holes 1003 to assemble the handle to the housing 10.

[0051] In a specific embodiment, in order to increase the service life of the explosion-proof and rupture-proof sampling bottle 1 while facilitating the transportation of the explosion-proof and rupture-proof sampling bottle 1, the shell 10 includes an inner liner body 101 and an outer shell 100 that is mounted on the outside of the inner liner body 101; wherein the material of the inner liner body 101 can be glass material.

[0052] Optionally, in the process of transferring the sample to the liquid, in order to prevent the inner liner body 101 from being impacted and thus causing the inner liner body 101 to break, the shell 10 and the bottle cap 12 can both be made of PVC, OPP, PI or PET materials.

[0053] In the several embodiments provided in this application, it should be understood that the disclosed systems, modules and methods can be implemented in other ways. For example, the module embodiments described above are merely illustrative. For example, the division of units is merely a logical function division. In actual implementation, there may be other division methods, such as multiple units or components can be combined or integrated into another system, or some features can be ignored or not executed. Another point is that the mutual coupling or direct coupling or communication connection shown or discussed can be through some interfaces, indirect coupling or communication connection of modules or units, which can be electrical, mechanical or other forms.

[0054] The above embodiments are intended only to illustrate the technical solutions of the present application and are not intended to limit them. The present application is not limited to the precise structures described above and illustrated in the accompanying drawings, and it cannot be assumed that the specific implementation of the present application is limited to these descriptions. For those skilled in the art of the present application, any changes and modifications made without departing from the concept of the present application should be deemed to fall within the scope of protection of the present application.
