[0032] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. Now, with reference to the accompanying drawings, the preferred embodiments of the present utility model will be described in detail.

[0033] An embodiment of the present utility model provides an auxiliary measuring tool 1000, as Figure 1 - Figure 2As shown, the auxiliary measurement tool 1000 includes a depth measurement rod 100, an extension rod 200, and a connector 300. The depth measurement rod 100 includes a first end 110 and a second end 120 that are oppositely arranged in the length direction. A scale 130 is provided on the outer side of the depth measurement rod 100. The extension rod 200 includes a third end 210 and a fourth end 220 that are oppositely arranged in its length direction. The third end 210 is installed on the second end 120. The connector 300 is installed on the fourth end 220. The connector 300 is used to install a locator. Exemplarily, a screw hole is provided on the locator, and a screw 310 adapted to the screw hole is provided on the connector 300, so that the locator can be detachably installed on the connector 300.

[0034] When this embodiment is in use, only the first end 110 of the depth measurement rod 100 needs to be inserted into the water, and the water depth can be measured through the scale 130 provided on the outer side of the depth measurement rod 100. The locator installed on the connector 300 can locate the measurement position while measuring the water depth. Installing a current meter on the depth measurement rod 100 and lowering it into the water together with the depth measurement rod 100 can obtain the flow velocity. Thus, the positioning, depth, and flow velocity required for the low-flow discharge measurement at the measurement position can be obtained.

[0035] Specifically, in this embodiment, by providing the extension rod 200 at the second end 120 of the depth measurement rod 100 and providing the connector 300 for installing the locator at the fourth end 220 of the extension rod 200 away from the depth measurement rod 100, when the auxiliary measurement tool 1000 is in use, the locator can be placed at a high point, the locator is closer to the open high altitude, reducing the influence of the surrounding environment on the signal and also reducing the signal interference caused by the human body. In addition, when the depth measurement rod 100 of this embodiment is in use, the locator will be directly above the depth measurement rod 100, so the positioning is more accurate.

[0036] Reference Figure 2 In a specific embodiment, the third end 210 and the second end 120 are detachably connected.

[0037] Specifically, the sum of the lengths of the depth measurement rod 100 and the extension rod 200 is relatively large. If the third end 210 is locked to the second end 120, it will be very inconvenient to carry and store the auxiliary measurement tool 1000. Exemplarily, when placing the auxiliary measurement tool 1000 in a vehicle, it will seriously affect the riding experience and there are also very large potential safety hazards. To solve this technical problem, in this embodiment, the third end 210 and the second end 120 are detachably connected. When carrying or storing is required, the depth measurement rod 100 and the extension rod 200 are separated, and when in use, the third end 210 and the second end 120 are connected together again. It should be noted that there are many solutions for the detachable connection between the third end 210 and the second end 120, and this embodiment does not limit it here.

[0038] Reference Figure 2 、 Figure 3 In a specific embodiment, one of a first external thread 211 and a first threaded hole (not shown in the figure) is provided on the third end portion 210, and the other of the first external thread 211 and the first threaded hole is provided on the second end portion 120. The first external thread 211 is adapted to the first threaded hole, so that the third end portion 210 and the second end portion 120 are detachably connected.

[0039] In this embodiment, the third end portion 210 and the second end portion 120 of the present embodiment are detachably connected by the cooperation of the first external thread 211 and the first threaded hole (not shown in the figure). This connection method is very stable and will not loosen easily when subjected to vibration and load. By implementing this embodiment, when the extension rod 200 needs to be installed on the depth measuring rod 100, only the second end portion 120 and the third end portion 210 need to be butted, and hold one of the depth measuring rod 100 and the extension rod 200, and rotate the other of the depth measuring rod 100 and the extension rod 200, or the depth measuring rod 100 and the extension rod 200 can be rotated in the opposite direction at the same time. When disassembly is required, as long as a reverse force opposite to the installation force is applied to the depth measuring rod 100 and / or the extension rod 200. It can be seen that in this embodiment, the disassembly and installation of the second end portion 120 and the third end portion 210 are very convenient.

[0040] In another specific embodiment, a first through hole (not shown in the figure) penetrating through the inner and outer sides of the depth measuring rod 100 is provided on the second end portion 120, and a second through hole (not shown in the figure) penetrating through the inner and outer sides of the extension rod 200 is provided on the third end portion 210. The third end portion 210 is sleeved outside the second end portion 120, or the second end portion 120 is sleeved outside the third end portion 210, so that the first through hole can move to be opposite to the second through hole; the auxiliary measuring tool 1000 further includes a pin (not shown in the figure). When the first through hole moves to be opposite to the second through hole, only by inserting the pin, the third end portion 210 and the second end portion 120 can be connected, and by pulling out the pin, the extension rod 200 and the depth measuring rod 100 can be disconnected. It can be seen that in this embodiment, the disassembly and installation of the second end portion 120 and the third end portion 210 are very convenient.

[0041] Reference Figure 4, in another specific embodiment, one of a clamping block 212 and a rotary slot 121 is provided on the outer side surface of the second end portion 120, and the other of the clamping block 212 and the rotary slot 121 is provided on the inner side surface of the third end portion 210. Only by aligning the clamping block 212 with the rotary slot 121 first and inserting the second end portion 120 into the third end portion 210 can the clamping block 212 be placed into the rotary slot 121. Subsequently, by rotating the clamping block 212, the clamping block 212 can be engaged with the rotary slot 121, realizing the connection between the second end portion 120 and the third end portion 210. When it is necessary to remove the extension rod 200 from the depth measuring rod 100, only by rotating the clamping block 212 in the reverse direction and then pulling out the extension rod 200 can it be done. Thus, it can be seen that in this embodiment, the disassembly and installation of the second end portion 120 and the third end portion 210 are very convenient.

[0042] Reference Figure 6 , in some embodiments, a wire clamping structure 140 is provided on the depth measuring rod 100, and the wire clamping structure 140 is used to limit the signal transmission line 9000 of the current meter.

[0043] Specifically, in order to facilitate knowing the test data of the current meter, the current meter generally has an external broadcasting module or a display module. When in use, the current meter is placed underwater, and the broadcasting module or the display module is placed above water. The broadcasting module or the display module is connected to the current meter through the signal transmission line 9000. The broadcasting module can broadcast the detection information of the detection module, and the display module can display the detection information of the detection module. If the signal transmission line 9000 is not limited, the signal transmission line 9000 is easily carried away by the water flow. Therefore, in this embodiment, a wire clamping structure 140 is provided on the depth measuring rod 100, and the wire clamping structure 140 is used to limit the signal transmission line 9000 of the current meter.

[0044] Reference Figure 6 , in a specific embodiment, the wire clamping structure 140 is a plurality of wire passing holes 141 penetrating through the inner and outer sides of the depth measuring rod 100, and the plurality of wire passing holes 141 are arranged at intervals in the length direction of the depth measuring rod 100. By threading the signal transmission line 9000 into the wire passing holes 141, the signal transmission line 9000 can be clamped on the depth measuring rod 100 to prevent the signal transmission line 9000 from being carried away by the water flow.

[0045] It is worth mentioning that the wire passing holes 141 are formed by subtractive processing, which not only has low processing cost, but also can reduce the weight of the depth measuring rod 100, and can reduce the burden to a certain extent when carrying the auxiliary measuring tool 1000.

[0046] In another specific embodiment, the wire clamping structure 140 is a plurality of wire clips, and the plurality of wire clips are arranged at intervals in the length direction of the depth measuring rod 100. The wire clips can apply a clamping force to the signal transmission line 9000 to prevent the signal transmission line 9000 from being carried away by the water flow.

[0047] Reference Figure 5 , in some embodiments, the connector 300 includes one of a second external thread 320 and a second threaded hole (not shown in the figure), and the fourth end 220 is provided with the other of the second external thread 320 and the second threaded hole. The second external thread 320 and the second threaded hole are adapted to each other so that the connector 300 and the fourth end 220 can be detachably connected, so that the user can replace the connector 300 as needed, increasing the versatility of the depth measuring rod 100.

[0048] In this embodiment, the connector 300 of the extension rod 200 is detachably connected by the cooperation of the second external thread 320 and the second threaded hole. This connection method is very stable and will not loosen easily when subjected to vibration and load.

[0049] Reference Figure 1 , in some embodiments, the auxiliary measuring tool 1000 further includes a disk body 400, and the disk body 400 is connected to a position of the first end 110 away from the second end 120.

[0050] Specifically, there are many stones at the bottom of the water, and the depth measuring rod 100 is easily inserted into the gaps between the stones. The standard depth starting position is the top surface of the stones. Therefore, if the depth measuring rod 100 is inserted into the position between the stones, it will cause inaccurate depth measurement. To solve this technical problem, in this embodiment, a disk body 400 is provided at a position of the first end 110 away from the second end 120, and the disk body 400 is used to abut against the top surface of the stones to ensure the accuracy of depth measurement.

[0051] Reference Figure 1 , in a specific embodiment, the auxiliary measuring tool 1000 further includes a spike 500, and the spike 500 is connected to a position of the first end 110 away from the second end 120, and the head of the spike 500 is arranged facing away from the second end 120.

[0052] Specifically, the spike 500 can be inserted into the gap between the stones, thereby increasing the stability of the auxiliary measuring tool 1000 during use.

[0053] Reference Figure 1 , in some embodiments, the disk body 400 is made of stainless steel. Since the auxiliary measuring tool 1000 is wading in water for a long time, the disk body 400 will be in a humid environment. Therefore, the disk body 400 made of stainless steel can effectively prevent the disk body 400 from rusting and extend its service life.

[0054] Reference Figure 1, in some embodiments, the depth measuring rod 100 is made of stainless steel. Since the auxiliary measuring tool 1000 is wading in water for a long time, the depth measuring rod 100 will be in a humid environment. Therefore, making the depth measuring rod 100 of stainless steel can effectively prevent the depth measuring rod 100 from rusting and extend its service life.

[0055] Reference Figure 1 , in some embodiments, the extension rod 200 is made of stainless steel. Since the auxiliary measuring tool 1000 is wading in water for a long time, the extension rod 200 will be in a humid environment. Therefore, making the extension rod 200 of stainless steel can effectively prevent the extension rod 200 from rusting and extend its service life.
