Description

Technical Field

[0001] This utility model relates to the technical field of water quality sampling equipment, and in particular to an environmental monitoring water quality sampler. Background Technology

[0002] Existing water sampling equipment is mainly used to collect water samples from different locations for subsequent water quality analysis and other work; it typically includes a sampling head, sampling pipe, water storage container, and control unit.

[0003] Existing water quality sampling equipment often only installs a small number of water storage containers through threaded connections. For example, the connection between the containers and other parts of the equipment is too complicated, possibly using multiple bolts, nuts, and threaded connections. Disassembly and assembly require a lot of time, and these small parts are easy to lose, further affecting the efficiency of disassembly and assembly. Therefore, this application designs an environmental monitoring water quality sampler to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an environmental monitoring water quality sampler.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an environmental monitoring water quality sampler, comprising a sampling box, wherein a liquid extraction pump is installed inside the sampling box, a sampling connection pipe is connected to the inlet end of the liquid extraction pump, a sampling seat is connected to the outlet end of the liquid extraction pump, a number of sampling tubes are spaced apart in the sampling seat, and a snap-fit ​​transmission mechanism for installing the sampling tubes is provided in the sampling seat.

[0006] Preferably, a first rotary valve is provided between the liquid extraction pump and the sampling connection pipe, and a second rotary valve is provided between the liquid extraction pump and the sampling seat.

[0007] Preferably, the other end of the sampling connection tube is threaded to a filter joint, the filter joint is provided with a baffle, and several anti-mud support rods are provided at equal intervals on the filter joint.

[0008] Preferably, the snap-fit ​​transmission mechanism includes a rubber card in the sampling seat and a mating rubber baffle on the sampling tube.

[0009] Preferably, the bottom end of the sampling tube is provided with a blocking soft pad, the sampling seat is provided with an infusion needle that extends into the blocking soft pad, and the sampling seat is provided with a detection spring that abuts against the bottom end of the sampling tube.

[0010] Preferably, the sampling box has four symmetrically arranged pulleys at its bottom and a push handle at its side.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In this utility model, through the cooperation of the filter connector and the anti-mud support rod, the water sample quality obtained by the water extraction is more stable due to the support of the anti-mud support rod and the filtering effect of the baffle, thereby improving the detection accuracy of the device. Furthermore, through the abutment cooperation of the rubber card and the matching rubber baffle, the sampling tube is easily and stably installed and fixed in the sampling seat, avoiding the need to spend a lot of time disassembling and installing these connecting parts, preventing the loss of these small parts, and enabling the sampling container to perform sampling and detection functions in conjunction with the detection spring. It also makes the disassembly of the sampling tube easier, thereby improving the efficiency of sampling tube disassembly and assembly, and ultimately solving the problem of low disassembly and replacement efficiency of water storage containers in existing water quality sampling equipment.

[0019] Example: See Figure 1-4This utility model discloses an environmental monitoring water quality sampler, comprising a sampling box 1, a liquid extraction pump 6 installed inside the sampling box 1, a sampling connection pipe 2 connected to the inlet end of the liquid extraction pump 6, and a sampling seat 8 connected to the outlet end of the liquid extraction pump 6. Several sampling tubes 13 are spaced apart in the sampling seat 8, which includes a snap-fit ​​transmission mechanism for mounting the sampling tubes 13. The liquid extraction pump 6, a WL-type vortex pump, allows for better extraction of water samples. A first rotary valve 5 is located between the liquid extraction pump 6 and the sampling connection pipe 2, and a second rotary valve 7 is located between the liquid extraction pump 6 and the sampling seat 8. These valves allow for better control of the opening and closing of the regulating device. A filter connector 3 is threaded to the other end of the sampling connection pipe 2. The filter connector 3 contains a baffle 14 and several anti-mud support rods 15 spaced evenly on it. The filter connector 3 effectively blocks impurities and extracts water samples. By utilizing the anti-mud support rod 15, the filter connector 3 can be better supported to prevent sludge from being sucked into the sampling device; the snap-fit ​​transmission mechanism includes a rubber card 9 in the sampling seat 8 and a matching rubber baffle 11 on the sampling tube 13. The rubber card 9 and the matching rubber baffle 11 can better fix the sampling tube 13 inserted into the sampling seat 8; the bottom end of the sampling tube 13 is provided with a blocking soft pad, the sampling seat 8 is provided with an infusion needle 10 that extends into the blocking soft pad, and the sampling seat 8 is provided with a detection spring 12 that abuts the bottom end of the sampling tube 13. The detection spring 12 can detect the insertion status of the sampling tube 13 in the sampling seat 8, thereby using the signal valve inside the sampling seat 8 to open and close to supply water sample to the sampling tube 13; four pulleys 4 are symmetrically provided at the bottom of the sampling box 1, and a push handle is provided at the side end of the sampling box 1. The pulleys 4 and the push handle can better move the device, making the sampling of the device more convenient.

[0020] Working principle: When using this utility model, first install a mobile power supply for the device, then push the device to the sampling point, then open the first rotary valve 5 and the second rotary valve 7, then connect the sampling pump 6 to the sampling connection pipe 2, and thread the filter connector 3 to the other end of the sampling connection pipe 2. The filter connector 3 can better block dirt and draw water samples. By using the anti-mud support rod 15, the filter connector 3 can be better supported to prevent sludge from being sucked into the sampling device. Then, install the sampling tube 13 on the sampling seat 8. The inserted sampling tube 13 is stably inserted into the sampling seat 8 through the cooperation of the rubber card 9 and the matching rubber baffle 11. The pipe and signal valve in the sampling seat 8 are detected by the sensing spring 12, which opens the corresponding abutment infusion needle 10 for the sampling tube 13 and starts the sampling pump 6 to draw water samples from the sampling tube 13. The use of the device is then completed.
