DETAILED DESCRIPTION

[0031] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0032] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] See also Figure 1 This embodiment provides a portable water quality monitor, including a monitoring probe 10, a carrying case 20, a flexible connector 30, a winding assembly 40 and a first limiting assembly 70. The winding assembly 40 is arranged inside the carrying case 20, one end of the flexible connector 30 is connected to the winding assembly 40, and the other end can extend to the outside of the carrying case 20 and be connected to the monitoring probe 10. The winding assembly 40 is used to rewind and unwind the flexible connector 30. The first limiting assembly 70 is arranged inside the carrying case 20 and is used to limit the winding assembly 40 to one-way rotation.

[0034] When there is no need to monitor the water quality, the winding assembly 40 is in a reeled state with respect to the flexible connector 30. At this time, the monitoring probe 10 is stored inside one side of the carrying case 20, thereby realizing the storage of the monitoring probe 10. When it is necessary to monitor the water quality, the monitoring probe 10 can be pulled, thereby driving the flexible connector 30 to be unwound from the winding assembly 40. The flexible connector 30 extends toward the outside of the carrying case 20, placing the monitoring probe 10 in the water, thereby realizing water quality monitoring.

[0035] See also Figure 1 In one embodiment, the winding assembly 40 includes a support shaft 401 and a winding drum 402 rotatably arranged outside the support shaft 401, one end of the flexible connecting member 30 is wound around the outside of the winding drum 402, and the winding drum 402 and the support shaft 401 are also connected by a first elastic member 403, and the first elastic member 403 is used to drive the winding drum 402 to rotate in the opposite direction along the outside of the support shaft 401.

[0036] When the monitoring probe 10 is pulled, the flexible connector 30 drives the winding drum 402 to rotate outside the support shaft 401, and the flexible connector 30 unwinds and stretches. When the water quality monitoring is completed, the first elastic member 403 drives the winding drum 402 to rotate in the opposite direction along the outside of the support shaft 401 to reel in the flexible connector 30, thereby pulling the monitoring probe 10 into the carrying case 20 to achieve storage and protection of the monitoring probe 10.

[0037] See also Figure 3In one embodiment, when the flexible connector 30 drives the winding drum 402 to rotate and the flexible connector 30 is unwound and stretched, the first limiting component 70 is used to limit the reverse rotation of the winding drum 402. A pressing member 80 is also provided on one side of the carrying case 20. The pressing member 80 is used to drive the first limiting component 70 to move to release the rotation restriction of the winding drum 402.

[0038] When the monitoring probe 10 is pulled to monitor the water quality, the flexible connecting member 30 is unwound and extended. At this time, the winding drum 402 rotates around the support shaft 401, and the first elastic member 403 is subjected to force. The first limiting component 70 limits the reverse rotation of the winding drum 402 to overcome the rotational force of the first elastic member 403 and prevent the winding drum 402 from rotating, ensuring that after the monitoring probe 10 is released, the winding drum 402 cannot reel in the flexible connecting member 30; when the water quality monitoring is completed, the pressing member 80 can drive the first limiting component 70 to move, thereby releasing the rotation restriction of the winding drum 402. At this time, the first elastic member 403 can drive the winding drum 402 to rotate in the opposite direction to reel in the flexible connecting member 30, and then pull the monitoring probe 10 into the carrying case 20 to achieve storage and protection of the monitoring probe 10.

[0039] See also Figure 2 and Figure 3 In one embodiment, a through hole 404 is formed on one side of the support shaft 401 and extends to the other side, a slide groove 202 is formed on one side of the carrying case 20, and the pressing member 80 includes a support rod 802 and a pressure rod 803, the support rod 802 passes through the through hole 404 and is rotatably connected to the through hole 404, one end of the pressure rod 803 is connected to the support rod 802, and the other end extends from the slide groove 202 to the outside of the carrying case 20, the first limiting assembly 70 includes a first limiting rod 701, a fourth elastic member 702 and The first tooth piece 703 is provided with several groups of annular structures at the end of the winding drum 402, one end of the first limiting rod 701 is a wedge-shaped structure, and the side wall of the first limiting rod 701 is provided with a first slot for one end of the support rod 802 to extend into, one end of the fourth elastic member 702 is connected to the support rod 802, and the other end is connected to the inner wall of the first slot, which is used to provide elastic support for the first limiting rod 701, so as to drive the end of the first limiting rod 701 with a wedge-shaped structure to extend between two adjacent groups of first tooth pieces 703.

[0040] When the monitoring probe 10 is pulled to drive the flexible connecting member 30 to extend, the winding drum 402 rotates to unwind the flexible connecting member 30. At this time, the first teeth 703 rotate synchronously to drive the first limiting rod 701 to adaptively reciprocate along the support rod 802. Since one end of the first limiting rod 701 is a wedge-shaped structure, the reverse rotation of the first teeth 703 can be restricted, that is, the reverse rotation of the winding drum 402 can be restricted, so as to realize the non-return effect of the winding drum 402 and ensure that the winding drum 402 cannot be immediately rotated after the monitoring probe 10 is released. The flexible connector 30 is reeled up; after the water quality monitoring is completed, the pressure rod 803 can be pressed, and the pressure rod 803 drives the support rod 802 to deflect, thereby driving the first limit rod 701 at one end of the support rod 802 to move, so that the end of the first limit rod 701 with a wedge-shaped structure is removed from between the two sets of first teeth 703. At this time, the rotation of the first elastic member 403 can drive the winding drum 402 to rotate in the opposite direction to automatically reel up the flexible connector 30, thereby pulling the monitoring probe 10 into the carrying box 20 for storage and protection.

[0041] See also Figure 3 In one embodiment, one side of the support rod 802 is further connected to the side wall of the support shaft 401 through a fifth elastic member 801 , and the fifth elastic member 801 is used to provide elastic tension to the support rod 802 .

[0042] When the monitoring probe 10 is moved into the carrying box 20, the pressure rod 803 is released. At this time, the support rod 802 can be driven to deflect in the opposite direction under the pull of the fifth elastic member 801, thereby driving the first limiting rod 701 to move in the opposite direction, so that the end of the first limiting rod 701 with a wedge-shaped structure is reinserted between two adjacent groups of first teeth 703, so that when the monitoring probe 10 is used subsequently, the non-return limit of the winding drum 402 can continue to be realized.

[0043] See also Figure 1 In one embodiment, the support shaft 401 is slidably installed inside the carrying box 20, and one side of the support shaft 401 is also connected to the inner wall of the carrying box 20 through a second elastic member 50. The second elastic member 50 is used to provide elastic tension to the support shaft 401. A second limiting component 60 is also provided inside the carrying box 20. The second limiting component 60 is used to limit the support shaft 401 to unidirectional movement.

[0044] In the process of pulling the monitoring probe 10 to drive the flexible connector 30 to unwind and stretch, the support shaft 401 can also be pulled and moved along the inside of the carrying box 20, so that the flexible connector 30 not only has the function of unwinding and stretching, but also has the function of moving and stretching. Through this dual stretching effect of the flexible connector 30, it is beneficial to reduce the volume of the carrying box 20 and improve the stretching effect of the flexible connector 30; in the process of the support shaft 401 being pulled and moved, the second elastic member 50 is stretched by force, and the support shaft 401 is limited to unidirectional movement by the second limit assembly 60, to avoid the second elastic member 50 pulling the support shaft 401 to move in the opposite direction after releasing the monitoring probe 10, thereby ensuring that the monitoring probe 10 can smoothly monitor the water quality.

[0045] See also Figure 3 In one embodiment, the second limiting assembly 60 includes a third elastic member 603, a second limiting rod 602 and a second tooth piece 601, and the second tooth piece 601 is arranged in a linear structure on the inner wall of the carrying case 20 in a plurality of groups at intervals. One end of the second limiting rod 602 is a wedge-shaped structure, and a second slot is provided on the side wall of the second limiting rod 602. The support rod 802 extends from one end of the first limiting rod 701 to the inside of the second slot. One end of the third elastic member 603 is connected to the inner wall of the second slot, and the other end is connected to the support rod 802, which is used to provide elastic support for the second limiting rod 602, so as to drive the end of the second limiting rod 602 with a wedge-shaped structure to extend between two adjacent groups of second tooth pieces 601.

[0046] When the support shaft 401 is pulled and moved, the second limiting rod 602 can be driven to move synchronously. The second limiting rod 602 can adaptively move back and forth along one end of the support rod 802 under the support of the third elastic member 603 and the second tooth pieces 601. The reverse movement of the second limiting rod 602 is limited by the second tooth piece 601, and the reverse movement of the support shaft 401 is further limited to ensure that after the monitoring probe 10 is released, the monitoring probe 10 does not move with the reverse movement of the support shaft 401; in water When the quality monitoring is completed and the pressure rod 803 is pressed, the pressure rod 803 drives the support rod 802 to deflect. When the support rod 802 deflects, it can drive the second limit rod 602 to move, so that the end of the second limit rod 602 with a wedge-shaped structure is removed from between the two adjacent sets of second tooth plates 601. At this time, under the pulling action of the second elastic member 50, the support shaft 401 is driven to move in the opposite direction along the inside of the carrying box 20, so as to pull the monitoring probe 10 through the flexible connecting member 30, so that the monitoring probe 10 is moved into the inside of the carrying box 20 for storage.

[0047] In one embodiment, the first elastic member 403 can be a coil spring or a torsion spring, which is not limited here. The second elastic member 50, the third elastic member 603, the fourth elastic member 702 and the fifth elastic member 801 can be springs or metal springs, which are not limited here.

[0048] See also Figure 1 In one embodiment, a guide rail 201 is fixedly provided on the inner wall of the carrying box 20 , and a slot (not shown in the figure) adapted to the guide rail 201 is opened at one end of the support shaft 401 .

[0049] See also Figure 1 In one embodiment, a handle 203 is further provided on one side of the carrying box 20 , and a jack for the monitoring probe 10 to enter and exit is opened on the side wall of the carrying box 20 .

[0050] In an embodiment of the present invention, when there is no need to monitor the water quality, the winding assembly 40 is in a reeled state with respect to the flexible connector 30. At this time, the monitoring probe 10 is stored inside one side of the carrying case 20, thereby realizing the storage of the monitoring probe 10. When it is necessary to monitor the water quality, the monitoring probe 10 can be pulled, thereby driving the flexible connector 30 to unwind from the winding assembly 40, and the flexible connector 30 extends toward the outside of the carrying case 20, placing the monitoring probe 10 in the water, thereby realizing water quality monitoring. Compared with the prior art, when water quality monitoring is not needed, the monitoring probe 10 can be stored and protected, and when water quality monitoring is needed, the monitoring probe 10 can be portable and extended, which has the advantages of good protection effect and convenient and quick operation.
