Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, and in particular to a sampler for testing the water quality of chemical wastewater. Background Technology

[0002] Water quality indicates the physical, chemical, and biological characteristics and composition of a water body. Protecting water quality is an important part of environmental protection. To determine water quality, chemical wastewater needs to be tested and approved before it can be discharged. Before testing water quality, water sampling is required, which necessitates the use of sampling instruments. Existing sampling devices often involve manually collecting water samples from rivers using containers at the riverbank. However, manual sampling not only increases the probability of workers falling into the river but also presents significant challenges in sampling deep water. For example, Chinese utility model patent CN221445484U solves the problem of manually collecting water samples from rivers using containers at the riverbank, which not only increases the probability of workers falling into the river but also presents significant challenges in sampling deep water.

[0021] The following section describes the present invention in further detail with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the scope of protection of the invention.

[0022] like Figure 1-5 As shown, a sampler for testing the water quality of chemical wastewater includes a sampling box 1 and a clamping unit 5. The top of the sampling box 1 is provided with a hand-held part 2. The sampling box 1 has a hollow interior and an open structure on one side. Each side wall is provided with multiple water-permeable holes 7. The clamping unit 5 is disposed inside the sampling box 1 and is used to clamp the sampling bottle.

[0023] In this invention, as one embodiment of the sampling box 1, it has a rectangular structure. Water-permeable holes 7 evenly distributed on the three side walls of the sampling box 1 facilitate the entry of sampling water from the sampling point into the sampling box 1, and then into the sampling bottle. Under the fixing action of the clamping unit 5, the sampling bottle will not move arbitrarily within the sampling box 1, ensuring sampling efficiency.

[0024] In one embodiment of this utility model, the clamping unit 5 includes a fixing ring 52 and clamping blocks 56. The fixing ring 52 is horizontally disposed above the bottom wall of the sampling box 1 and is connected and fixed to the bottom wall of the sampling box 1 through a support unit. Multiple clamping blocks 56 are provided, and the multiple clamping blocks 56 are disposed inside the fixing ring 52 and are evenly distributed along the circumference of the fixing ring 52. The fixing ring 52 is provided with driving members that correspond one-to-one with the multiple clamping blocks 56. The driving end of the driving member is connected and fixed to the clamping block 56 and drives the clamping block 56 to move closer to or away from the central axis of the fixing ring 52.

[0025] In this invention, the sampling bottle is placed inside the fixing ring 52. Under the action of the driving component, the clamping block 56 is driven to move closer to the central axis of the fixing ring 52 to clamp and fix the sampling bottle. To improve the fixing effect of the clamping block 56, a rubber washer can be provided on the clamping block 56 to increase the friction between the clamping block 56 and the sampling bottle. Preferably, the clamping block 56 of this invention has a sheet-like structure, is vertically arranged, and has an arc segment 57 at its upper end. The arc segment 57 is used for guidance to facilitate the handling of the sampling bottle. The clamping unit 5 of this invention has the advantages of simple structure, good clamping and fixing effect, and convenient operation.

[0026] As an embodiment of this utility model, the driving component includes a driving rod 58 and a spring 59. The driving rod 58 is horizontally arranged, with one end passing through the fixing ring 52 and fixedly connected to the clamping block 56, and the other end provided with a limiting disc 55. The driving rod 58 can move radially along the fixing ring 52. The spring 59 is sleeved on the outside of the driving rod 58, with one end connected and fixedly connected to the clamping block 56, and the other end connected and fixedly connected to the inner wall of the fixing ring 52.

[0027] In this invention, the potential energy generated by the elastic deformation of the spring 59 serves as the power to drive the drive rod 58 and the clamping block 56 to move, eliminating the need for an external electric drive device and achieving the clamping of the sampling bottle. The drive component of this invention has advantages such as simple structure, low energy consumption, and precise driving direction.

[0028] As an embodiment of this utility model, an adsorption element is provided above the fixing ring 52. The adsorption element is used to adsorb bottle caps. The support unit includes multiple electric telescopic rods 51. The multiple electric telescopic rods 51 are all fixed on the bottom wall of the sampling box 1 and are distributed at intervals along the circumference of the fixing ring 52. The driving end of the electric telescopic rod 51 is fixedly connected to the bottom of the fixing ring 52 to drive the fixing ring 52 to move up and down to approach or move away from the adsorption element.

[0029] In this invention, to prevent the water sample in the sampling bottle from spilling, after sampling, the electric telescopic rod 51 drives the fixing ring 52 to move the sampling bottle upwards until it is close to the bottle cap, which then seals the sampling bottle. To ensure the support and fixation of the fixing ring 52, multiple connecting rods 54 are also provided. Similarly, one end of each connecting rod 54 is connected and fixed to the bottom wall of the sampling box 1, and the other end passes through the fixing ring 52. The fixing ring 52 can slide up and down along the axial direction of the connecting rods 54. Furthermore, the connecting rods 54 also ensure the straightness of the moving trajectory of the fixing ring 52.

[0030] In one embodiment of this utility model, a storage tray 53 is provided on the bottom wall of the sampling box 1, and a connecting block is provided on the electric telescopic rod 51. The storage tray 53 is connected and fixed to the connecting block. When the sampling bottle is placed in the fixing ring 52, it is placed on the storage tray 53. At the same time, the storage tray 53 can provide a supporting surface for the sampling bottle. When the fixing ring 52 moves the sampling bottle upward, it prevents the sampling bottle from falling off and affecting the sampling results. Preferably, the storage tray 53 is embedded in the bottom wall of the sampling box 1, and multiple water-permeable holes 7 are evenly distributed on it.

[0031] In one embodiment of this utility model, the adsorption element is a suction cup 510.

[0032] In this invention, the suction cup 510 has the advantages of strong adsorption force and low implementation cost.

[0033] As an embodiment of the present invention, a spraying unit 6 is also included, which is disposed in the sampling box 1 and is used to rinse and clean the sampling bottle.

[0034] As an embodiment of this utility model, the spraying unit 6 includes a water tank 61, a water pump 63, and a spray pipe 62. The sampling box 1 is provided with a partition, which divides the interior of the sampling box 1 into two independent upper and lower parts. The clamping unit 5 is disposed below the partition, the adsorption element is disposed at the bottom of the partition, the water tank 61 is disposed at the upper end of the partition, one end of the spray pipe 62 is connected and communicates with the interior of the water tank 61, and the other end extends to be fixed on the bottom wall of the sampling box 1. Multiple nozzles 65 are evenly distributed on the spray pipe 62, and the nozzles 65 are disposed towards the clamping unit 5.

[0035] In this invention, the space on the partition serves as a mounting groove for installing the water tank 61. A water pump 63 is fixed to the partition, and a spray pipe 62 extends through the partition to the bottom wall of the sampling box 1. Multiple nozzles 65 are evenly spaced along the axial direction of the spray pipe 62. Under the action of the water pump 63, water from the water tank 61 is pumped into the spray pipe 62, and then sprayed out from the nozzles 65 to rinse and clean the sampling bottles. The more spray pipes 62 there are, the better the rinsing effect on the sampling bottles. Ideally, this invention has four spray pipes 62, distributed and installed at the four right angles of the sampling box 1. Correspondingly, there are also four water pumps 63.

[0036] In one embodiment of this utility model, the handheld part 2 is provided with a control handle 3, and a controller is integrated inside the control handle. The water pump 63 and the electric telescopic rod 51 are both electrically connected to the controller, and the controller controls the starting and stopping of the water pump 63 and the electric telescopic rod 51. The control handle improves the intelligence of the sampling operation and increases the sampling efficiency.
