Description

Technical Field

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

[0002] Water sampling equipment is a tool or device used to collect representative water samples from various water bodies. Its core function is to ensure that the collected water samples can truly reflect the actual quality of the water body, providing a reliable sample basis for subsequent water quality testing, analysis and evaluation.

[0003] In existing technologies, water sampling equipment can be flexibly used in outdoor sampling scenarios through its movable components at the bottom. In the high temperatures of southern summers, where the ambient temperature may approach 40°C, most existing technologies only provide simple heat dissipation by installing fans and vents within the enclosure. The lack of airflow guidance channels easily leads to heat accumulation on the surface of the main control enclosure, causing aging of the electronic components inside and shortening the equipment's lifespan. Furthermore, the heat sinks in most existing technologies are independent structures, lacking linkage with the airflow guidance channels, thus reducing heat dissipation efficiency. Utility Model Content

[0004] The main purpose of this utility model is to provide a water quality sampling device that improves the heat dissipation performance of the device through the combination of a guide channel and a heat dissipation block.

[0005] The technical solution of this utility model is as follows:

[0006] A water quality sampling device includes a main control box, a storage box, and a wind-cooled heat dissipation structure located outside the main control box. The main control box is located on the side of the storage box away from the ground. The wind-cooled heat dissipation structure includes a fan and a ventilation rack.

[0007] One end of the ventilation frame is located in the main control box and the other end is located in the storage box. The ventilation frame has several ventilation openings on the side away from the fan. The inner wall of the ventilation frame has several directional flow guide grooves. The main control box has several flow guide heat dissipation blocks on the side facing the ventilation frame to assist the directional flow guide grooves.

[0008] In one possible implementation, each of the heat dissipation blocks and directional heat dissipation channels is parallel to the installation direction of the device, and the heat dissipation blocks and directional heat dissipation channels are arranged sequentially at intervals.

[0009] In one possible implementation, the directional guide channel is provided with a plurality of guide strips, and each guide strip has an arc-shaped longitudinal section.

[0010] In one possible implementation, the main control box is provided with an installation structure that facilitates the quick installation of the air-cooled heat dissipation structure. The installation structure includes an installation guide rail and an installation slider. The installation guide rail is located on the side of the main control box facing the ventilation frame, and the installation slider is located on the side of the ventilation frame facing the main control box. The installation slider is slidably connected to the installation guide rail.

[0011] In one possible implementation, the ventilation rack has a fixing block on the side facing the storage box, and the storage box has a limiting groove on the side facing the fixing block, with the fixing block embedded in the limiting groove.

[0012] In one possible implementation, the longitudinal section of each of the heat dissipation blocks is an arc-shaped structure.

[0013] In one possible implementation, each of the ventilation openings has a rectangular cross-section, and the ventilation openings are arranged sequentially at intervals.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] When the ambient temperature is too high, the fan is activated to generate airflow. This airflow is guided by the directional guide groove inside the ventilation frame and the auxiliary guide of the heat dissipation block on the outside of the main control box, guiding the airflow to the ventilation opening and forming an efficient heat dissipation channel that can quickly remove the heat accumulated on the surface of the main control box.

[0016] This invention utilizes a directional airflow channel with linear guide strips in conjunction with an arc-shaped airflow-guiding heat dissipation block. Both guide the airflow simultaneously, and finally, through a rectangular vent, ensure that the hot airflow is evenly discharged, significantly improving heat dissipation efficiency and ensuring stable operation of the main control box. Furthermore, the cooperation of mounting rails, mounting sliders, fixing blocks, and limiting grooves enables rapid installation and structural stability of the air-cooled heat dissipation structure, making operation convenient and the connection secure.

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0027] like Figures 1-5 As shown, this embodiment proposes a water quality sampling device, the structure of which includes a main control box 1 and a storage box 4, with the main control box 1 located on the side of the storage box 4 away from the ground. It also includes a wind-cooled heat dissipation structure 2 located outside the main control box 1, which reduces the possibility of external dust or water entering the main control box 1 through the wind-cooled heat dissipation structure 2 and damaging electronic components, while also preventing interference between the heat dissipation components and the electronic components inside the main control box 1.

[0028] In this embodiment, the electrical components inside the main control box 1, close to the housing of the main control box 1, generate heat that is transferred to the housing of the main control box 1, and then rapidly dissipated by the air-cooled heat dissipation structure 2 on the outside of the main control box 1. Furthermore, in this embodiment, the air-cooled heat dissipation structure 2 can be placed in different locations or in different numbers within the main control box 1, depending on the actual situation. For example, if heat is concentrated on the other side of the main control box 1, the air-cooled heat dissipation structure 2 can be placed on that side; if the ambient temperature of the equipment is high or the heat dissipation requirement of the main control box 1 is large, the number of air-cooled heat dissipation structures 2 can be increased to enhance the heat dissipation capacity. Further details are not elaborated upon in this embodiment.

[0029] The air-cooled heat dissipation structure 2 includes a fan 21 and a ventilation frame 22. The ventilation frame 22 is located on the side facing the main control box 1. The sides of the ventilation frame 22 facing both the main control box 1 and the storage box 4 are open, which can better dissipate heat from the main control box 1 and also save on the manufacturing cost of the ventilation frame 22. The fan 21 is located inside the ventilation frame 22, which provides a stable installation position for the fan 21 and ensures the stability of this embodiment. The side of the ventilation frame 22 away from the fan 21 has several ventilation openings 23. The fan 21 and each ventilation opening 23 form a heat dissipation channel. The air blown out by the fan 21 can carry away the heat accumulated on the outside of the main control box 1 and then be evenly discharged through each ventilation opening 23.

[0030] In this embodiment, the cross-section of the vent 23 is rectangular. Compared with other structures, the rectangular structure is more regular, allowing multiple vents 23 to be placed in the same area. Furthermore, the manufacturing process of the rectangular structure is mature, which can save on processing costs. The vents 23 are arranged sequentially at intervals, which can discharge air evenly and stably. At the same time, the arrangement of multiple vents 23 reduces the possibility of large external debris, such as fallen leaves or pieces of paper, entering the air-cooled heat dissipation structure 2.

[0031] In this embodiment, the inner wall of the ventilation frame 22 is provided with several directional airflow guide grooves 24 to regulate the airflow direction of the fan 21, ensuring that the airflow flows through the main control box 1 along a preset path and is discharged from each ventilation port 23, thereby improving the airflow utilization rate. Furthermore, the side of the main control box 1 facing the ventilation frame 22 is provided with several airflow guiding and heat dissipation blocks 25 to assist the directional airflow guide grooves 24 in guiding the airflow. These blocks can cooperate with the directional airflow guide grooves 24 to further optimize the airflow direction, making the airflow more closely conform to the surface of the main control box 1. On the other hand, the airflow guiding and heat dissipation blocks 25 can increase the heat dissipation area of ​​the main control box 1, enhance the heat exchange efficiency with the airflow, and improve the heat dissipation performance of this embodiment.

[0032] In this embodiment, the orientation of each heat dissipation block 25 is consistent with the mainstream airflow direction, which reduces airflow resistance and allows for smoother airflow. The spacing between the heat dissipation blocks 25 ensures that each block can fully contact the airflow, uniformly removing heat. Furthermore, the orientation of each directional airflow channel 24 is consistent with the mainstream airflow direction, guiding the airflow along a preset mainstream direction. The spacing between the directional airflow channels 24 ensures even airflow distribution among the channels, working in conjunction with the heat dissipation blocks 25 to improve the heat dissipation uniformity and efficiency of this embodiment.

[0033] In this embodiment, the directional flow channel 24 is provided with several guide strips 241 to ensure uniform airflow distribution within the ventilation frame 22, reducing the possibility of excessively high or low local flow velocities. Each guide strip 241 has an arc-shaped longitudinal section and a continuous wave structure, which flexibly disperses the airflow, reducing local stress concentration in the directional flow channel 24 and improving the service life of this embodiment. Simultaneously, the arc-shaped guide strips 241 reduce obstruction to airflow, allowing the airflow to flow more efficiently along the directional flow channel 24, enhancing the overall guiding effect and improving the flow guidance performance of this embodiment.

[0034] In this embodiment, the cross-section of each heat dissipation block 25 perpendicular to the installation direction of the device is an arc-shaped structure. Compared with the rectangular structure, the arc-shaped structure can maximize the contact area with the airflow within the same volume, so that the heat dissipation block 25 can fully contact the airflow and transfer the heat of the main control box 1 to the airflow. This, combined with the directional heat dissipation groove 24, achieves high-efficiency heat dissipation and improves the heat dissipation performance of this embodiment.

[0035] In this embodiment, the main control box 1 is provided with an installation structure 3 for quick installation of the air-cooled heat dissipation structure 2. The installation structure 3 includes an installation guide rail 31 and an installation slider 32. The installation guide rail 31 is located on the side of the main control box 1 facing the ventilation frame 22, and the installation slider 32 is located on the side of the ventilation frame 22 facing the main control box 1. The installation slider 32 is slidably connected to the installation guide rail 31, and the two are on corresponding installation surfaces, which can be accurately aligned during installation. At the same time, the sliding connection facilitates the disassembly and maintenance of the air-cooled heat dissipation structure 2, further improving the convenience of installation or disassembly in this embodiment.

[0036] Furthermore, this embodiment is equipped with two mounting guide rails 31 and mounting sliders 32, which can provide linear guidance at both ends during installation and disassembly, improving the stability of sliding. At the same time, the mounting guide rails 31 all adopt dovetail grooves, which improves the stability of the air-cooled heat dissipation structure 2 after installation and reduces the shaking of the air-cooled heat dissipation structure 2 caused by operation or environmental influences.

[0037] In this embodiment, the ventilation frame 22 has a fixing block 33 on the side facing the storage box 4, and the storage box 4 has a limiting groove 34 on the side facing the fixing block 33. The fixing block 33 is embedded in the limiting groove 34, and the edge of the limiting groove 34 has a chamfer to guide the fixing block 33, which improves the installation speed. By using the fixing block 33 to fit into the limiting groove 34, the connection stability of this embodiment can be further improved on the basis of sliding connection, reducing the lateral sway of the ventilation frame 22, reducing the possibility of the ventilation frame 22 loosening or shifting during operation of this embodiment, and also ensuring the stability of heat dissipation effect.
