Description

Technical Field

[0001] This utility model belongs to the technical field of automatic water sample collectors, and specifically relates to an automatic water sample collector for mixed water samples. Background Technology

[0002] With the increasing national emphasis on water environment management, online monitoring systems for water pollution sources have become an important technical means for environmental supervision. Automatic water samplers, as a key component, are responsible for providing representative samples to online monitoring instruments. Automatic mixed water samplers are a new type of automatic water sampler capable of continuous tracking and sampling of water samples discharged from pollution sources, automatic mixing and storage, abnormal alarms, cold storage of samples, and system self-cleaning. They are widely used in various environmental monitoring scenarios, including online monitoring of pollution sources, monitoring of wastewater treatment plant inlets and outlets, industrial emission supervision, and river section water quality monitoring. The equipment can be used in conjunction with various online analytical instruments for COD, ammonia nitrogen, total phosphorus, total nitrogen, and heavy metals. Through its flow tracking sampling and continuous mixed sample output functions, it effectively improves the representativeness and accuracy of monitoring data. This automatic water sample collector consists of multiple functional modules, including a control module, a flow tracking sampling module, an A / B tank mixed sample storage module, an over-limit sample retention and alarm module, a cold storage module, an automatic cleaning and emptying module, and a linkage communication module. These modules work collaboratively, have a compact structure, and clearly defined functions. The control module, as the core control unit, is responsible for coordinating the sampling process, data processing, and communication control. The flow tracking sampling module connects to the flow meter and automatically adjusts the operating speed of the sampling pump based on the received instantaneous flow signal to achieve proportional flow sampling. The collected water sample first enters the A tank, where it forms a homogeneous mixture under the action of the mixing module. This mixture is then continuously supplied to the online monitoring system via a delivery system. When the online instrument detects that water quality indicators exceed the standard, the overall control module immediately commands a path switch to import the water sample from that period into container B for retention. At the same time, the alarm module is activated to issue an audible and visual alarm and record the data. The cold storage module preserves the water samples in containers A and B at low temperatures to prevent sample deterioration. The automatic cleaning and emptying module is activated after the sampling cycle ends to automatically flush the mixing container, pipelines, etc., to prevent cross-contamination. The communication module supports data exchange and parameter setting with a host computer or remote platform through various protocols, ensuring that the equipment's operating status can be monitored and remotely controlled. These modules work together to achieve full-process integration from automatic sampling, mixing, and retention to intelligent monitoring and remote communication, adapting to various complex application scenarios.

[0003] However, in practical use, existing automatic water sample collectors for mixing water samples require mixing and stirring structures on tanks A and B. These structures use stirring to fully mix water samples collected at different times and locations, forming a mixed water sample that reflects the overall water quality. However, most traditional collectors use fixed brackets to directly fix the mixing and stirring structures on tanks A and B. When the mixing and stirring structure malfunctions or requires maintenance, maintenance personnel often need to spend a lot of time and effort to disassemble the fixed brackets to remove the mixing and stirring structure from the tanks for inspection, reducing the convenience of maintenance of the automatic water sample collector. On the other hand, the fixed bracket installation method is also not conducive to the initial assembly of the automatic water sample collector, resulting in low assembly efficiency. Therefore, this utility model proposes an automatic water sample collector for mixing water samples. Utility Model Content

[0015] 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.

[0016] Example 1 Please see Figures 1 to 4 This is the first embodiment of the present invention, which provides a technical solution: an automatic water sample collector, comprising a main body 1, a cold storage chamber 2 installed inside the main body 1, barrels A5 and B6 installed inside the main body 1, a drug delivery pump 3 and a sample supply pump 4 installed inside the main body 1 and located on one side of barrel A5, valve bodies 7 being provided between barrel B6 and the cold storage chamber 2, and between barrel A5 and barrel B6, for water sample transport, and a mixing and stirring structure 8 being installed on the top of barrels A5 and barrel B6, the mixing and stirring structure 8 including a top frame 81, and a device installed on the top of the top frame 81. The motor 82 and the stirring shaft 83, which is rotatably installed at the bottom of the top frame 81 and connected to the output end of the motor 82, are inserted into the inside of the tanks A5 and B6. Stirring paddles 84 are installed on both sides of the stirring shaft 83. The specific model of this automatic mixed water sampler is "M8-S5 type fully automatic AB double tank excessive water quality sampler". The above structure is a technology that has been disclosed in the prior art and does not involve the technical improvement part of this application. For the specific structural principle, please refer to the existing patent with publication number CN222212343U. It will not be elaborated here. The mixing structure 8 also includes a plug-in quick-install structure 85; The plug-in quick-install structure 85 includes two bottom plug blocks 852 welded and fixed to the bottom of the top frame 81. Two side sockets 851 corresponding to the bottom plug blocks 852 are symmetrically welded and fixed to the surfaces of both barrels A5 and B6. The surface of each side socket 851 has a through-hole 854 for inserting the bottom plug block 852. A support block 853 is fixed to the side of each bottom plug block 852. The bottom end of the bottom plug block 852 is inserted into the through-hole 854, and the support block 853 rests on the top surface of the side socket 851. The plug-in quick-install structure 85 also includes two L-shaped movable plates 855 movably installed on the top surface of the top frame 81. The bottom ends of the two L-shaped movable plates 855 extend to the sides of the two side sockets 851, and a triangular side locking block 856 is welded and fixed to the inner side of the bottom end of each L-shaped movable plate 855. The side of each side socket 851 has a through-hole for the triangular side locking block 856. When the triangular side locking block 856 is engaged in the rectangular side locking slot 857, it can effectively limit the L-shaped movable plate 855 and the top frame 81, ensuring the stable installation of the top frame 81 and thus ensuring the installation stability of the mixing structure 8. If the mixing structure 8 needs to be disassembled for inspection and maintenance, simply pull the L-shaped movable plate 855 to the side, so that the triangular side locking block 856 moves out of the rectangular side locking slot 857, which can quickly release the limitation on the bottom insert block 852 and the top frame 81. At this time, lift the top frame 81 to separate the bottom insert block 852 from the side socket 851, and the mixing structure 8 can be quickly disassembled for inspection and maintenance. This solves the problem of installation and maintenance of the mixing structure 8 in traditional automatic water sample collectors, and improves the maintenance convenience and usage efficiency of the entire collector.

[0017] In this embodiment, preferably, the plug-in quick-install structure 85 further includes a support guide plate 858 welded and fixed to the top surface of the top frame 81, and the top end of the L-shaped movable plate 855 extends laterally through the support guide plate 858, so that the L-shaped movable plate 855 can slide laterally on the top of the top frame 81 smoothly. The support guide plate 858 is provided with a transverse hole for the L-shaped movable plate 855 to pass through.

[0018] In this embodiment, preferably, a guide rod 8581 is fixed on the side of the supporting guide plate 858 relative to the top of the L-shaped movable plate 855, and a top plate 8551 corresponding to the guide rod 8581 is fixed on the top of the L-shaped movable plate 855. The top plate 8551 is slidably sleeved on the guide rod 8581, so that the L-shaped movable plate 855 can slide laterally on the top of the top frame 81 stably. During the sliding process, the top plate 8551 and the guide rod 8581 play a guiding and supporting role.

[0019] In this embodiment, preferably, a spring 859 is sleeved between the surface of the guide rod 8581 and the support guide plate 858 and the top plate 8551. Under the pushing of the spring 859, the L-shaped movable plate 855 can be tightly attached to the side of the top frame 81 during daily use, and the bottom end of the L-shaped movable plate 855 can be tightly attached to the side of the side socket 851. This allows the triangular side locking block 856 to be stably locked in the rectangular side locking slot 857, ensuring the limiting stability of the top frame 81 and the bottom plug 852. When the operator pulls the L-shaped movable plate 855 to the side, the top plate 8551 will slide to the side and further compress the spring 859 until the triangular side locking block 856 moves out of the rectangular side locking slot 857, so that the top frame 81 can be lifted smoothly to complete the separation of the bottom plug 852 and the side socket 851.

[0020] In this embodiment, preferably, one end of the spring 859 abuts against the side of the top plate 8551, and the other end of the spring 859 abuts against the side of the support guide plate 858.

[0021] In this embodiment, preferably, both barrel A5 and barrel B6 are provided with a liquid delivery pipe 9 on one side for delivering water samples.

[0022] Example 2 Please see Figures 1 to 5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that a side notch 8541 is provided on one side of the inner wall of the insertion hole 854, and a rubber side block 8542 is embedded in the side notch 8541. The surface of the rubber side block 8542 is provided with an integral rubber abutment block 8543 that abuts against the side of the bottom insertion block 852, so that the bottom insertion block 852 can be abutted by the rubber abutment block 8543 after being inserted into the insertion hole 854, preventing loosening. Both the rubber side block 8542 and the rubber abutment block 8543 are made of rubber material, which will undergo elastic deformation when squeezed, which can prevent loosening without affecting the normal insertion and removal operation of the bottom insertion block 852.

[0023] In this embodiment, preferably, the rubber side block 8542 has an elliptical deformation cavity inside, so that the rubber pressing block 8543 and the rubber side block 8542 are easy to undergo elastic deformation when squeezed, and have sufficient deformation space.

[0024] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
