Description
Technical Field
[0001] This utility model relates to the technical field of water quality sampling and analysis instruments, specifically a portable water quality sampling and analysis instrument for water conservancy projects. Background Technology
[0002] A water quality sampling and analysis instrument is a device used to collect water samples and analyze and detect various water quality indicators. It is widely used in many fields such as environmental protection, water conservancy projects, medical and health care, scientific research and teaching. It can analyze and detect a variety of water quality parameters, including but not limited to physical, chemical and biological indicators.
[0003] In existing technologies, to facilitate the sampling and analysis of water quality in water conservancy projects while maintaining portability, handheld water quality sampling analyzers are typically used. These analyzers connect a conduit and a sampling head to the analyzer, extending the sampling head into the riverbed for water quality sampling and analysis. However, in practical use, due to the length of the conduit, it is often loosely held by hand after sampling and analysis. Users must hold the conduit firmly to prevent it from becoming loose and being dragged along the ground, affecting the portability of the analyzer. Furthermore, the conduit may be damaged by hard objects on the ground during dragging. Therefore, a portable water quality sampling analyzer for water conservancy projects is needed to address these issues. Utility Model Content
[0004] The purpose of this invention is to provide a portable water quality sampling and analysis instrument for water conservancy projects to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable water quality sampling and analysis instrument for water conservancy projects, comprising a handheld water quality sampling and analysis instrument body, an external sleeve-and-retract mechanism for the handheld water quality sampling and analysis instrument body, a storage mechanism for the right side of the sleeve-and-retract mechanism, a connection interface for the back of the handheld water quality sampling and analysis instrument body, a plug for the internal connection interface, a conduit fixedly installed at the end of the plug away from the connection interface, and a sampling head fixedly installed at the end of the conduit away from the plug.
[0006] Preferably, the sleeve-and-retract mechanism includes a friction sleeve, which is slidably mounted on the outside of the handheld water quality sampling and analysis instrument body. A rotation limit seat is fixedly mounted on the bottom of the friction sleeve, and a winding roller is rotatably mounted inside the rotation limit seat. A limit frame is fixedly mounted on the outside of the winding roller, a turning cross block is fixedly mounted on the right side of the winding roller, and a limit cross insertion hole block is fixedly mounted on the left side of the winding roller. A spring telescopic rod is fixedly mounted on the left side of the rotation limit seat, and a limit insertion post is fixedly mounted on the bottom of the spring telescopic rod, so as to facilitate the storage of the conduit through the sleeve-and-retract mechanism.
[0007] Preferably, the limiting cross socket block has a hole inside, and the limiting pin is slidably installed inside the hole inside the limiting cross socket block, so as to limit the rotation of the limiting cross socket block by means of the limiting pin.
[0008] Preferably, the limiting frame has a rectangular hole inside, and the conduit is disposed inside the rectangular hole inside the limiting frame, so as to limit the conduit through the limiting frame.
[0009] Preferably, the rotating limiting seat has holes at the corresponding positions of the winding roller, and the winding roller is rotatably installed inside the holes opened inside the rotating limiting seat, which facilitates the normal winding and storage of the guide tube.
[0010] Preferably, the storage mechanism includes a storage tube, which is fixedly installed on the right side of the friction sleeve. A pad is fixedly installed on the top of the storage tube, and an independent spring and a sliding rod are fixedly installed on the top of the pad. A baffle is slidably installed on the outside of the sliding rod to facilitate the storage and placement of the sampling head through the storage mechanism.
[0011] Preferably, the independent spring is disposed outside the slide rod, and the end of the independent spring away from the pad is fixedly installed on the top inner side of the baffle, so that the baffle can properly block the opening of the storage tube.
[0012] Compared with the prior art, this utility model provides a portable water quality sampling and analysis instrument for water conservancy projects, which has the following beneficial effects:
[0013] 1. This portable water quality sampling and analysis instrument for water conservancy projects features a sleeve-and-retract mechanism. During use, after the plug is unplugged from the interface, rotating the cross block and using the limiting frame to rotate the winding roller allows the conduit to be wound up. Simultaneously, a spring telescopic rod and a limiting pin limit the rotation of the limiting cross block, and the retractor also stores the sampling head, preventing the conduit from loosening after winding. The assembled friction sleeve does not damage the structure of the handheld water quality sampling and analysis instrument; it can be used directly after being fitted. When carrying the handheld water quality sampling and analysis instrument, it can be held with one hand, effectively preventing the conduit from being dragged on the ground due to loosening, and also preventing damage to the conduit from foreign objects on the ground.
[0014] 2. This portable water quality sampling and analysis instrument for water conservancy projects, through its built-in storage mechanism, can store and place the sampling head during use using the built-in storage tube, preventing it from being exposed to the outside and being bumped. The elastic force of an independent spring can also make the baffle block and limit and fix the sampling head, thus realizing the function of storing and protecting the sampling head.

A rotation limit seat 22 is fixedly mounted on the bottom of the friction sleeve 21. A winding roller 23 is rotatably mounted inside the rotation limit seat 22. A limit frame 24 is fixedly mounted on the outside of the winding roller 23. A turning cross block 25 is fixedly mounted on the right side of the winding roller 23. A limit cross insertion block 26 is fixedly mounted on the left side of the winding roller 23. A spring telescopic rod 27 is fixedly mounted on the left side of the rotation limit seat 22. A limit insertion post 28 is fixedly mounted on the bottom of the spring telescopic rod 27, which facilitates the storage of the tube 6 by the sleeve-mounted tube receiving mechanism 2.
[0027] Furthermore, the limiting cross socket block 26 has a hole inside, and the limiting pin 28 is slidably installed inside the hole inside the limiting cross socket block 26, so as to limit the rotation of the limiting cross socket block 26 by means of the limiting pin 28.
[0028] Furthermore, a rectangular hole is provided inside the limiting frame 24, and the conduit 6 is placed inside the rectangular hole provided inside the limiting frame 24, so as to limit the conduit 6 through the limiting frame 24.
[0029] Furthermore, holes are provided at the corresponding positions of the rotating limit seat 22 and the winding roller 23, and the winding roller 23 is rotatably installed inside the holes provided inside the rotating limit seat 22, which facilitates the normal winding and storage of the guide tube 6.
[0030] Example 2:
[0031] Please see Figure 5 Furthermore, in conjunction with Embodiment 1, the storage mechanism 3 includes a storage tube 31, which is fixedly installed on the right side of the friction sleeve 21. A pad 32 is fixedly installed on the top of the storage tube 31. An independent spring 33 and a slide rod 34 are fixedly installed on the top of the pad 32. A baffle 35 is slidably installed on the outside of the slide rod 34 to facilitate the storage and placement of the sampling head 7 through the storage mechanism 3.
