Description

Technical Field

[0001] This utility model relates to the field of water quality sampling technology, and in particular to a water quality sampling and storage device for water conservancy and hydropower construction. Background Technology

[0002] Water quality sampling during hydropower construction refers to the periodic collection of water samples during the construction process to monitor water quality changes and pollution levels. Analysis of various water quality indicators, such as turbidity, pH, dissolved oxygen, and chemical oxygen demand (COD), ensures that construction activities will not pollute water sources or the surrounding ecological environment. Water quality sampling helps to promptly identify pollution sources, implement effective control measures, and ensure the safety of water quality in the construction area and downstream, complying with environmental regulations. The sampling process must follow standard operating procedures to ensure the representativeness and accuracy of the samples. Typically, after sampling, the water samples need to be sent to a laboratory for detailed testing. During transportation, a water quality sampling and storage device for hydropower construction is required to ensure sample accuracy.

[0003] According to the Chinese patent "A Water Quality Testing Sampling Preservation Box" authorized announcement number "CN221341849U", this device can fix the storage bottle inside the storage box. When the top cover is closed, the bottle cap contacts the sponge at the bottom of the top cover, so that the sponge holds the bottle cap in place to prevent the bottle cap from falling off the storage bottle, thereby achieving the effect of preventing the sample from spilling.

[0004] The above application allows the bottle cap to contact the sponge at the bottom of the top cover when the top cover is closed, which can prevent the bottle cap from detaching from the storage bottle. However, when the boxes are assembled, the storage bottle is fixed inside the storage box. When encountering bumps during transportation, the storage bottle will shake violently along with the storage box. The violent shaking of the sample may cause errors in the test results.

[0005] Therefore, a water quality sampling and storage device for water conservancy and hydropower construction is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a water quality sampling and storage device for water conservancy and hydropower construction in order to solve the above-mentioned problems, thereby improving the problem of severe shaking during sample transportation.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: a water quality sampling and storage device for water conservancy and hydropower construction, comprising: a box body and a box cover, wherein the box cover is hinged to one side of the top of the box body, and multiple storage bottles are arranged inside the box body;

[0008] The shock absorption mechanism includes a fixed plate fixedly connected to the inner wall of the box and a sliding plate slidably connected to the inner wall of the box. The sliding plate is located below the fixed plate. A first cylinder and a plurality of second cylinders are provided between the sliding plate and the inner bottom wall of the box. The plurality of second cylinders are all connected to the first cylinder.

[0009] Preferably, the plurality of storage bottles pass through the fixing plate, and the bottom end of the storage bottle contacts the sliding plate. This facilitates sampling and use of the storage bottles.

[0010] Preferably, a second piston is slidably connected to the inner wall of the second cylinder, and the top end of the second piston extends through the second cylinder and is fixedly connected to a circular block. The upper surface of the circular block is fixedly connected to a sliding plate. This allows the pressure on the sliding plate to be absorbed more evenly.

[0011] Preferably, a second spring is provided between the second piston and the inner bottom wall of the second cylinder, with the top end of the second spring fixedly connected to the second piston and the bottom end fixedly connected to the inner bottom wall of the second cylinder. This allows the second piston to quickly return to its original position.

[0012] Preferably, the first cylinder is fixedly connected to the inner bottom wall of the housing, and the first cylinder is arranged horizontally, with two second cylinders connected to each end of the first cylinder. This allows for more thorough interaction between the gas in the first cylinder and the second cylinders.

[0013] Preferably, a fixing block is fixedly connected to the middle inner wall of the first cylinder, and a first piston is provided at both ends of the fixing block. The first piston is slidably connected to the inner wall of the first cylinder, and a first spring is fixedly connected between the fixing block and the first piston. This allows the pressure inside the first cylinder to enter the first cylinder more quickly.

[0014] Preferably, the surface of the box is provided with a handle, and the rotation axis of the handle is located on both sides of the box. This facilitates the use of the box.

[0015] The beneficial effects of this utility model are:

[0016] 1. By placing the storage bottle on the fixed plate with its bottom in contact with the sliding plate, the entire box moves upward when it is bumped, while the sliding plate remains stationary due to inertia. Through the compression of the gas in the second cylinder and the interaction with the gas in the first cylinder, the sliding plate is made to reduce shaking during the bumping process, thus avoiding errors in sample detection caused by violent oscillation.

[0017] 2. By setting the storage bottle in a fixed plate, the storage bottle can only move up and down, which improves the stability of the storage bottle in the box. At the same time, when sampling, the storage bottle can be directly removed for sampling, making the sampling work more convenient for staff. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In practical implementation: such as Figure 1-4 As shown, a water quality sampling and storage device for water conservancy and hydropower construction includes: a box body 100 and a box cover 110. The box cover 110 is hinged to one side of the top of the box body 100, and a plurality of storage bottles 300 are arranged inside the box body 100.

[0025] The shock absorption mechanism 200 includes a fixed plate 210 fixedly connected to the inner wall of the housing 100 and a sliding plate 220 slidably connected to the inner wall of the housing 100. The sliding plate 220 is located below the fixed plate 210. A first cylinder 230 and a plurality of second cylinders 240 are provided between the sliding plate 220 and the inner bottom wall of the housing 100. The plurality of second cylinders 240 are all connected to the first cylinder 230.

[0026] like Figure 2 , Figure 3 and Figure 4As shown, a second piston 242 is slidably connected to the inner wall of the second cylinder 240. The top end of the second piston 242 extends through the second cylinder 240 and is fixedly connected to a circular block 241. The upper surface of the circular block 241 is fixedly connected to the sliding plate 220. A second spring 243 is provided between the second piston 242 and the inner bottom wall of the second cylinder 240. The top end of the second spring 243 is fixedly connected to the second piston 242 and the bottom end is fixedly connected to the inner bottom wall of the second cylinder 240. The first cylinder 230 is fixedly connected to the inner bottom wall of the housing 100. The first cylinder 230 is arranged horizontally. Two second cylinders 240 are respectively connected to both ends of the first cylinder 230. A fixing block 231 is fixedly connected to the middle inner wall of the first cylinder 230. A first piston 232 is provided at both ends of the fixing block 231. The first piston 232 is slidably connected to the inner wall of the first cylinder 230. A first spring 233 is fixedly connected between the fixing block 231 and the first piston 232.

[0027] In this embodiment, the communication position between the second cylinder 240 and the first cylinder 230 is located above the second piston 242. When the housing 100 is not subjected to bumps, the pressure between the fixed block 231 and the two ends of the first cylinder 230 is equal to the pressure between the second piston 242 and the inner top wall of the second cylinder 240, and equal to the pressure between the second cylinder 240 and the inner bottom wall. When the housing 100 is subjected to bumps, the second piston 242 will remain in its original position briefly under the action of inertia, and the second cylinder 240 will move upward. Before the second piston 242 moves upward, the gas in the first cylinder 230 has already entered the second cylinder. Within cylinder 240, due to resistance in sliding the second piston 242 within the cylinder 240, the second piston 242 can only move upward a very short distance, simultaneously causing the sliding plate 220 to move upward and produce a small wobbling. However, the wobbling amplitude is greatly reduced because the sample also needs to be slightly shaken during testing, so the small wobbling will not cause errors in the test results. The bottom of the storage bottle 300 is arc-shaped, and the upper surface of the sliding plate 220 is provided with an arc-shaped groove that matches it. A cushioning sponge is provided in the arc-shaped groove. The storage bottle 300 consists of a bottle body and a bottle cap that is threaded onto its top.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, multiple storage bottles 300 penetrate the fixing plate 210, and the bottom end of the storage bottle 300 contacts the sliding plate 220. A handle 120 is provided on the surface of the box body 100, and the rotation axis of the handle 120 is located on both sides of the box body 100. The handle 120 consists of two horizontal bars and one vertical bar, forming a "C" shape. The two horizontal bars are rotatably connected to the rotation axis located on both sides of the box body 100. The length of the two horizontal bars is greater than the maximum distance from the rotation axis to the box cover 110. The vertical bar is fixedly connected between the two horizontal bars.

[0029] When using this utility model, when staff need to take water samples, they can directly open the box 100, take out the storage bottle 300, place the sample in the storage bottle 300, and then put the storage bottle 300 back in its original position. After the sampling is completed, the box 100 is closed and then transported to the laboratory for testing.

[0030] During transport, when the container 100 encounters a bump, the entire container 100 will move upwards. Simultaneously, the sliding plate 220 will briefly remain in place due to its own weight and the inertia generated by the weight of the storage bottle 300. At this time, the container 100 will drive the second cylinder 240 to move upwards. The second piston 242 will also briefly remain in place due to the inertia of the sliding plate 220. The upward movement of the second cylinder 240, in conjunction with the piston, compresses the gas inside, pushing the second piston 242 upwards. At this point, the second piston 242 and the inner bottom wall of the second cylinder 240... As the pressure increases, the pressure between the second piston 242 and the inner top wall of the second cylinder 240 decreases. At the same time, the pressure between the first piston 232 and the two ends of the first cylinder 230 is greater than the pressure between the second piston 242 and the inner top wall of the second cylinder 240. The first spring 233 will push the two first pistons 232 to move back and forth, thereby increasing the pressure between the second piston 242 and the inner top wall of the second cylinder 240, reducing the pressure difference between the upper and lower ends of the second piston 242 and the second cylinder 240, reducing the upward movement of the second piston 242, and thus reducing the up-and-down swaying amplitude of the sliding plate 220.

[0031] After the bumps subside, the housing 100 drives the second cylinder 240 back to its initial position. During the bumps, the second piston 242 moves upward slightly. When the housing 100 stabilizes and the second cylinder 240 returns to its initial position, the second spring 243 will be in an extended state and will slowly pull the second piston 242 back to its initial position, so that the pressure in each part of the first cylinder 230 and the second cylinder 240 returns to its initial value and remains stable.

[0032] It should be noted that the first spring 233 and the second spring 243 mentioned above are both devices with relatively mature existing technology. The specific models can be selected according to actual needs, and will not be elaborated here.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider 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.
