Description

Technical Field

[0001] This utility model relates to the field of rain gauge technology, and more specifically, to a tipping bucket rain gauge that is easy to fix. Background Technology

[0002] In the field of meteorological monitoring, tipping bucket rain gauges are important instruments for measuring rainfall. However, existing tipping bucket rain gauges have many technical shortcomings in practical applications, mainly in the following aspects:

[0003] First, the existing tipping bucket rain gauge installation process has obvious shortcomings. Installation usually requires the use of various professional tools such as wrenches and screwdrivers, and the operation steps are numerous and complicated. This installation method not only increases the installation time and labor costs, but also places high demands on the professional skills of the installers. Especially in some installation environments with complex terrain or limited space, the cumbersome installation process further highlights its limitations and seriously affects the installation efficiency of the equipment.

[0004] Secondly, although some improved rain gauges have appeared on the market, attempting to simplify the installation process by adding quick-installation devices, these devices still have significant problems in practical applications. Specifically, the structural design of these quick-installation devices is too simple and lacks necessary reinforcement and protection mechanisms. In harsh outdoor environments, especially when facing extreme weather such as strong winds and heavy rain, the installation structure is prone to loosening or even falling off. This lack of structural stability not only affects the accuracy of measurement data but may also lead to equipment damage and increase maintenance costs.

[0005] More importantly, since tipping bucket rain gauges need to work in outdoor environments for extended periods, they are inevitably affected by various environmental factors. Foreign objects such as fallen leaves, dust, and insect carcasses can easily be blown in by the wind or accumulate in the water collection funnel and tipping mechanism, causing blockages in the equipment. Such blockages not only affect the accuracy of rainfall measurement and disrupt the continuity and reliability of data, but may also cause water leakage and shorten the service life of the equipment.

[0031] Please see Figures 1-5A conveniently fixed tipping bucket rain gauge includes a rain gauge body 1. A protective device is provided on the outside of the rain gauge body 1, comprising a protective cover 2, a rain catcher 3, and a support foot 4. The rain gauge body 1 is detachably mounted on a base 40. The protective cover 2 is detachably mounted on top of the base 40 via threads. The support foot 4 is detachably mounted below the base 40. The rain catcher 3 is detachably connected to the top of the protective cover 2. A fixing device is provided on one side of the support foot 4, comprising a fixing plate 5, a fixing sleeve 6, a fixing rod 7, a fixing block 8, a push spring 9, a push plate 10, a fixing groove 11, and a sliding groove 12. The fixing plate 5 is located below the support foot 4, and the fixing sleeve 6 can... The fixing block 8 is engaged in the fixing groove 11 and the fixing rod 7 is disassembled. The push plate 10 is connected to the inner wall of the fixing sleeve 6 through the push spring 9. The fixing groove 11 is opened at the top inside the fixing sleeve 6. The sliding groove 12 is opened in the inner wall of the fixing sleeve 6. A positioning mechanism is provided on the outside of the fixing rod 7. The positioning mechanism includes a longitudinal groove 13, an annular groove 14, a positioning groove 15, a positioning sleeve 16 and a positioning rod 17. The bottom end of the longitudinal groove 13 is connected to the annular groove 14. The annular groove 14 is opened in the outer wall of the fixing rod 7. Multiple positioning grooves 15 are opened in the annular groove 14. Multiple positioning rods 17 are slidably arranged on the side wall of the fixing sleeve 6. The positioning sleeve 16 is movably sleeved on the outside of the fixing sleeve 6 through threads.

[0032] A mounting groove 18 is provided on the inner side of the fixing rod 7, and a return spring 19 is movably installed in the mounting groove 18. One side of the fixing block 8 is connected to the inner wall of the mounting groove 18 through the return spring 19.

[0033] The fixing block 8 has a chamfered structure on one side, and the top of the fixing groove 11 and the sliding groove 12 are both chamfered. The chamfer on one side of the fixing block 8 is equal to the chamfer at the top of the fixing groove 11 and the sliding groove 12.

[0034] A connecting spring 20 is provided on the outside of the fixed sleeve 6, and one end of the positioning rod 17 is connected to the outer wall of the fixed sleeve 6 through the connecting spring 20.

[0035] The ends of the positioning rod 17 and the edges of the side walls of the positioning groove 15 are rounded.

[0036] In this embodiment, when it is necessary to fix the tipping bucket rain gauge body, firstly, the tipping bucket rain gauge is installed on the base 40, then the protective cover 2 is installed above the base 40, so that the protective cover 2 is outside the rain gauge body 1, then the filter plate 21 is placed in the rain collector 3, and then the filter plate 21 is installed and fixed by the mounting sleeve 23. Then, firstly, the positioning sleeve 16 is rotated clockwise, so that the positioning sleeve 16 moves along the thread provided on the outside of the fixing sleeve 6, then the positioning sleeve 16 no longer limits the positioning rod 17, then the fixing sleeve 6 is rotated clockwise, the fixing sleeve 6 will drive multiple positioning rods 17 to move, then the side wall of the positioning groove 15 presses against the end of the positioning rod 17. Due to the rounded corner design at the end of the positioning rod 17 and the edge of the side wall of the positioning groove 15, then the positioning rod 17... One end of the positioning rod 17 will slide out of the positioning groove 15 and enter the annular groove 14, while the other end of the positioning rod 17 will drive the connecting spring 20 to stretch. At the same time, the fixing sleeve 6 will drive the fixing groove 11 and the sliding groove 12 opened on the inner side to rotate. Since the chamfer structure of the inner wall of the fixing groove 11 matches the chamfer structure on one side of the fixing block 8, the inner wall of the fixing groove 11 will press against one side of the fixing block 8, causing the fixing block 8 to be pressed. Then the fixing block 8 will gradually detach from the fixing groove 11 and enter the mounting groove 18. At the same time, the fixing block 8 will press against the reset spring 19 set on one side. When one end of the positioning rod 17 slides into the other positioning groove 15, the connecting spring 20 will drive the positioning rod 17 to reset, so that the positioning rod 17 is inserted into the positioning groove 15 here. A noticeable jamming feeling will be felt. At this time, stop. The rotating fixed sleeve 6 is stopped, and at this time the position of the slide groove 12 corresponds to the position of the fixed block 8. Then the return spring 19 resets and pushes the fixed block 8 to slide out of the mounting groove 18. Then the fixed block 8 will enter the slide groove 12. Then the push spring 9 will push the push plate 10 to reset, so that the push plate 10 pushes the fixed sleeve 6 and the fixed rod 7 to separate. Then the positioning rod 17 will enter the longitudinal groove 13 and slide along the longitudinal groove 13. The fixed block 8 will slide along the slide groove 12. Then the fixed sleeve 6 and the fixed rod 7 will be pulled up and down to the upper and lower sides respectively, so that the fixed sleeve 6 and the fixed rod 7 will be completely removed. Then the fixed rod 7 will pass through the pre-drilled mounting holes on the fixed plate 5 and the support foot 4 from below. Then the fixed sleeve 6 will be fitted onto the outside of the fixed rod 7 from above the support foot 4. The fixing block 8 slides into the slide groove 12, and then the positioning rod 17 slides into the longitudinal groove 13. The top of the fixing rod 7 then presses the push spring 9 through the push plate 10. When the push spring 9 is pressed to its limit, the fixing block 8 slides into the top of the slide groove 12. Then, the fixing sleeve 6 is rotated clockwise again, and the chamfer of the side wall at the top of the slide groove 12 presses against the fixing block 8, causing the fixing block 8 to retract into the mounting groove 18 and press against the return spring 19 again. Then, the positioning groove 15 at the bottom of the longitudinal groove 13 presses against one end of the positioning rod 17, causing one end of the positioning rod 17 to slide out of the positioning groove 15 and enter the annular groove 14. Then, the other end of the positioning rod 17 drives the connecting spring 20 to stretch. When the positioning rod 17 moves to the position corresponding to another positioning groove 15,The connecting spring 20 drives the positioning rod 17 to reset, causing one end of the positioning rod 17 to insert into the positioning groove 15. Simultaneously, the fixing groove 11 moves to the position corresponding to the fixing block 8. Then, the reset spring 19 pushes the fixing block 8 to slide out of the mounting groove 18 and into the fixing groove 11. Next, the positioning sleeve 16 rotates in the opposite direction, causing it to rotate and reset along the thread. The inner wall of the positioning sleeve 16 then limits the outer end of the positioning rod 17, preventing it from moving. The positioning rod 17, in conjunction with the positioning groove 15, limits the fixing sleeve 6, ensuring that the fixing sleeve 6 can only rotate with the fixing rod 7. This guarantees the stability of the fixing structure and, consequently, the stable fixing of the tipping bucket rain gauge.

[0037] Please see Figure 1 and Figure 2 As a further implementation of the overall equipment: a filter plate 21 is detachably provided on the inner side of the rain collector 3. The filter plate 21 has multiple filter holes 22. An installation sleeve 23 is provided on one side of the filter plate 21. The installation sleeve 23 is detachably installed on the top of the rain collector 3 by means of threads.

[0038] A side plate 24 is provided above the filter plate 21, and the side plate 24 is fixedly connected to the filter plate 21.

[0039] Multiple anti-slip strips 25 are provided on the outer side of the mounting sleeve 23.

[0040] More specifically, when the device is needed, rainwater first enters between the side plate 24 and the filter plate 21, then enters the rain collector 3 through the filter holes 22, and then enters the rain gauge body 1 inside the protective cover 2, thereby enabling the rain gauge body 1 to measure the rainfall. The protective cover 2 prevents the external environment from affecting the rain gauge body 1. The filter plate 21 and filter holes 22 prevent foreign objects from entering the rain gauge body 1 and causing blockage. The side plate 24 facilitates the collection and cleaning of intercepted foreign objects. The mounting sleeve 23 ensures the stable installation of the filter plate 21. The anti-slip strip 25 improves the anti-slip ability and operating feel of the outer side of the mounting sleeve 23. When the filter plate 21 needs to be cleaned, simply unscrew the mounting sleeve 23, remove the filter plate 21, and then fix the filter plate 21 inside the rain collector 3 using the mounting sleeve 23.

[0041] In summary, when using or operating the overall equipment: First, when fixing the tipping bucket rain gauge body, install the tipping bucket rain gauge on the base 40. Then, install the protective cover 2 above the base 40, ensuring the protective cover 2 is outside the rain gauge body 1. Next, place the filter plate 21 in the rain collector 3, and then fix the filter plate 21 using the mounting sleeve 23. Then, first, rotate the positioning sleeve 16 clockwise, causing it to move along the threads on the outside of the fixing sleeve 6. Then, the positioning sleeve 16 no longer limits the positioning rod 17. Next, rotate the fixing sleeve 6 clockwise, causing multiple positioning rods 17 to move. Then, the sidewall of the positioning groove 15 presses against the end of the positioning rod 17. Due to the pressure between the end of the positioning rod 17 and the edge of the sidewall of the positioning groove 15... The rounded corner design at the location allows one end of the positioning rod 17 to slide out of the positioning groove 15 and into the annular groove 14, while the other end of the positioning rod 17 drives the connecting spring 20 to stretch. Simultaneously, the fixing sleeve 6 drives the inner fixing groove 11 and the sliding groove 12 to rotate. Because the chamfered structure of the inner wall of the fixing groove 11 matches the chamfered structure on one side of the fixing block 8, the inner wall of the fixing groove 11 presses against one side of the fixing block 8, causing the fixing block 8 to be compressed. The fixing block 8 then gradually detaches from the fixing groove 11 and enters the mounting groove 18. At the same time, the fixing block 8 presses against the reset spring 19 on one side. When one end of the positioning rod 17 slides into another positioning groove 15, the connecting spring 20 drives the positioning rod 17 to reset, allowing the positioning rod 17 to insert into the positioning groove 14. At step 5, a noticeable jamming sensation will be felt. At this point, stop rotating the fixing sleeve 6, and the position of the slide groove 12 corresponds to the position of the fixing block 8. Then, the return spring 19 resets and pushes the fixing block 8 out of the mounting groove 18. The fixing block 8 will then enter the slide groove 12. Then, the push spring 9 pushes the push plate 10 to reset, causing the push plate 10 to push the fixing sleeve 6 and the fixing rod 7 to separate. Then, the positioning rod 17 will enter the longitudinal groove 13 and slide along the longitudinal groove 13, while the fixing block 8 will slide along the slide groove 12. Then, pull the fixing sleeve 6 and the fixing rod 7 up and down respectively to completely remove the fixing sleeve 6 and the fixing rod 7. Then, the fixing rod 7 passes through the pre-drilled mounting holes on the fixing plate 5 and the support foot 4 from below the fixing plate 5. The fixing sleeve 6 fits onto the outside of the fixing rod 7 from above the support foot 4, allowing the fixing block 8 to slide into the slide groove 12. Then, the positioning rod 17 slides into the longitudinal groove 13. The top of the fixing rod 7 then presses the push spring 9 through the push plate 10. When the push spring 9 is pressed to its limit, the fixing block 8 slides into the top of the slide groove 12. Then, the fixing sleeve 6 is rotated clockwise again, and the chamfer on the side wall of the top of the slide groove 12 presses the fixing block 8, causing the fixing block 8 to retract into the mounting groove 18 and press the return spring 19 again. Then, the positioning groove 15 at the bottom of the longitudinal groove 13 presses one end of the positioning rod 17, causing one end of the positioning rod 17 to slide out of the positioning groove 15 and into the annular groove 14. Then, the other end of the positioning rod 17 drives the connecting spring 20 to stretch.When the positioning rod 17 moves to the position corresponding to the other positioning groove 15, the connecting spring 20 drives the positioning rod 17 to reset, so that one end of the positioning rod 17 is inserted into the positioning groove 15. At the same time, the fixing groove 11 moves to the position corresponding to the fixing block 8. Then, the reset spring 19 pushes the fixing block 8 to slide out of the mounting groove 18 and into the fixing groove 11. Then, the positioning sleeve 16 is rotated in the opposite direction, so that the positioning sleeve 16 rotates and resets along the thread. Then, the inner wall of the positioning sleeve 16 limits the outer end of the positioning rod 17, so that the positioning rod 17 will not move. Then, the positioning rod 17, together with the positioning groove 15, limits the fixing sleeve 6, so that the fixing sleeve 6 can only rotate with the fixing rod 7, thereby ensuring the stability of the fixing structure and thus ensuring the stable fixing of the tipping bucket rain gauge.

[0042] When the device is needed, rainwater first enters between the side plate 24 and the filter plate 21, then enters the rain collector 3 through the filter holes 22, and then enters the rain gauge body 1 inside the protective cover 2, thus enabling the rain gauge body 1 to measure the rainfall. The protective cover 2 prevents the external environment from affecting the rain gauge body 1. The filter plate 21 and filter holes 22 prevent foreign objects from entering the rain gauge body 1 and causing blockage. The side plate 24 facilitates the collection and cleaning of intercepted foreign objects. The mounting sleeve 23 ensures the stable installation of the filter plate 21. The anti-slip strip 25 improves the anti-slip ability and operating feel of the outer side of the mounting sleeve 23. When the filter plate 21 needs to be cleaned, simply unscrew the mounting sleeve 23, remove the filter plate 21, and then fix the filter plate 21 inside the rain collector 3 using the mounting sleeve 23.
