Description

Technical Field

[0001] This utility model relates to a water quality testing vehicle, specifically a water quality testing vehicle for environmental monitoring in coal mines, belonging to the field of environmental monitoring technology in coal mines. Background Technology

[0002] The coal mine water quality testing vehicle is a mobile testing device that integrates water sample collection, on-site pretreatment, rapid detection and analysis, data storage and transmission. Its core principle is to use modular testing units to conduct rapid quantitative and qualitative analysis of water quality parameters for specific water quality indicators in and around coal mines using physical, chemical or biological testing methods. This provides accurate data support for coal mine water resource utilization, wastewater treatment and environmental monitoring, and is a key device for solving coal mine water quality monitoring.

[0003] However, most existing testing vehicles have open trays set up next to the operating table or testing equipment. The trays generally do not have limiting components to fit the water sample containers. When testing in coal mines, the testing vehicles need to move on bumpy roads such as underground mine entrances and mining area dirt roads. During the journey, the trays shake with the vehicle, causing the containers to shake randomly inside the trays. The containers are also prone to damage when they collide with the trays, which in turn affects the normal testing of water samples. Utility Model Content

[0004] The purpose of this utility model is to provide a water quality testing vehicle for environmental monitoring in coal mines in order to solve the above problems. The sampling frame limits the lateral position of the base plate and the card plate to prevent the sample storage component from shifting when sliding, and at the same time limits the sliding distance of the slider to prevent the sample storage component from being pulled out excessively and causing the water sample to spill.

[0005] This utility model achieves the above-mentioned objectives through the following technical solution: a water quality testing vehicle for environmental monitoring in coal mines, comprising a carriage, an operating table installed inside the carriage, a continuous flow analyzer and a sampling frame placed on the operating table, a sample storage mechanism slidably installed inside the sampling frame, the sample storage mechanism comprising a pull rod and a base plate, several base plates equidistantly slidably installed inside the sampling frame, ball bearings rotatably installed inside the sampling frame, the ball bearings being rolledly connected to the base plates, two sets of support rods fixedly connected to the base plates, a clamping plate fixedly fixed to the support rods, a pull rod fixed to one end of the base plate and the clamping plate, a slider fixedly connected to the end of the clamping plate opposite to the pull rod, several insertion holes equidistantly provided on the clamping plate, and washers adhered to the part of the clamping plate near the insertion holes.

[0006] Preferably, the sample storage mechanism further includes insertion holes and locking holes, and a plurality of locking holes and insertion holes are provided equidistantly in the base plate and the locking plate, and the inner diameter of the washer is equal to the diameter of the locking hole.

[0007] Preferably, the layout frame has a plurality of equidistant sliding grooves, and a base plate and a clamping plate are slidably installed on the sliding grooves, and the width of the base plate and the clamping plate is equal to the width of the sliding groove.

[0008] Preferably, the layout frame is provided with several sets of limiting grooves at equal intervals, and a slider is slidably installed in the limiting groove.

[0009] Preferably, the part of the layout frame that contacts the slider has an arc-shaped structure, and the length of the limiting groove is less than the length of the base plate and the clamping plate.

[0010] Preferably, the bottom end of the base plate is configured as an isosceles trapezoid, and the protruding part of the tie rod is configured as an arc surface.

[0011] Preferably, a water collection mechanism is connected to the operating platform. The water collection mechanism includes a washing pool and a filter screen. The washing pool is fixedly installed inside the operating platform, and the filter screen is snapped onto the washing pool.

[0012] Preferably, the water collection mechanism further includes a faucet and a sampling faucet. The faucet is installed on the part of the operating table near the washing pool, and the sampling faucet is connected inside the operating table.

[0013] The beneficial effects of this utility model are as follows: the protruding part of the pull rod has an arc-shaped structure, which avoids hand injuries to operators when pulling it out. The pull rod is integrated with the base plate and the card plate, and the double-layer sample storage structure can be pulled out simultaneously, improving the efficiency of water sample retrieval. The contact area between the base plate and the ball bearing is uniform, making the sliding more stable. The support rod forms a double-layer structure, which is convenient for storing water sample containers. The width of the base plate and the card plate is equal to that of the sliding groove, which prevents shaking during sliding and prevents water sample from tipping over. The holes are evenly distributed, which can orderly fix multiple water sample containers and avoid collisions and contamination caused by random placement of containers. The gasket is made of elastic material, which can tightly wrap the outer wall of the water sample container, enhance the fixing effect, and prevent the container from tipping over when the testing vehicle moves. At the same time, it avoids hard contact between the container and the card plate, reducing the risk of container breakage. The slider slides into the limiting groove, which can accurately limit the maximum pulling distance of the sample storage mechanism, preventing the sample storage mechanism from completely detaching from the sample placement frame and causing the water sample to tip over, thus ensuring the safety of water samples during mobile testing in coal mines.
