[0002] River basin is an important ecological system, and its hydrological characteristics and ecological environment directly affect the utilization of water resources, ecological balance and economic development in the basin. Traditional river basin ecological hydrological monitoring mainly relies on manual sampling and laboratory analysis, which has the disadvantages of low efficiency, high cost, poor data real-time performance, etc., and is difficult to meet the needs of modern water resources management and ecological protection.

[0003] In recent years, with the rapid development of sensor technology, communication technology and computer technology, automated and intelligent ecological hydrological monitoring equipment has gradually become a research hotspot, and various surveying and mapping equipment is increasing, but the existing surveying and mapping equipment still has some problems, as follows:

If a fixed structure is not used for installation, the stability of the surveying and mapping platform cannot be guaranteed, which will also lead to inaccurate surveying and mapping results. Therefore, we propose an ecological hydrological surveying and mapping equipment for river basin. SUMMARY

DETAILED DESCRIPTION

[0040] The technical solutions of the present invention will be described clearly and completely below in conjunction with the drawings in the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The ecological hydrological surveying and mapping equipment for river basins involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0041] See also Figure 1-8The utility model provides an ecological hydrology surveying and mapping equipment for river basin, two outer shell bodies 1 are fixedly installed with top cap 2 on the top end, the top end of top cap 2 is opened with air inlet groove, the top end middle part of top cap 2 is fixedly installed with outer drive motor 3, the output shaft of outer drive motor 3 is fixedly installed with upper center rod 4, the side of outer shell body 1 is opened with straight groove 5, the inside of outer shell body 1 is movably installed with buoy 6, the bottom end of upper center rod 4 is fixedly installed with lower center rod 7, the inside of buoy 6 is arranged with upper magnetic ring subassembly 8 and lower magnetic ring subassembly 9 in layers, the side of buoy 6 is fixedly installed with limit block 10, the inside of buoy 6 is fixedly installed with support ring 11, the top end of support ring 11 is fixedly installed with gas separation bin 12, the upper of gas separation bin 12 is fixedly installed with adjusting subassembly 13, the lower surface of gas separation bin 12 is fixedly installed with first spring 14, the outside of buoy 6 is fixedly installed with side connecting rod 15, the upper of side connecting rod 15 is opened with through groove 16, the upper of side connecting rod 15 is fixedly installed with transmission rack assembly 17, the side of side connecting rod 15 is fixedly installed with support base 18, the rotation of support base 18 is installed with driven gear 19, the bottom end of transmission rack assembly 17 is installed with suspension assembly 20, the bottom end of suspension assembly 20 is fixedly installed with surveying and mapping platform 21;

[0042] Compared with the prior art, the present application is provided with two symmetrical outer shells 1, and a float 6 that can move up and down is set between the two outer shells 1. The up and down movement of the float 6 is automatically floating according to the change of the water level. In this way, the surveying and mapping equipment can automatically adjust the height of the surveying and mapping platform 21 as the water level changes. Moreover, due to the limit setting, the horizontal stability of the surveying and mapping platform 21 at the bottom can be guaranteed, and it will not shake with the fluctuation of the water surface, thereby greatly improving the accuracy of surveying and mapping. At the same time, since the height of the surveying and mapping platform 21 is driven by the rotation of the driven gear 19 to drive the transmission rack assembly 17 is lifted by the lateral movement, so that the driven gear 19 of different sizes can be replaced according to the actual situation, so that the transmission ratio can be controlled, and then the surveying and mapping platform 21 can be controlled to rise to different heights, which greatly improves the flexibility of the device. At the same time, an adjustment component 13 is provided inside the float 6, and the adjustment component 13 is used to control the input of gas. In this way, the locking plug 94 can be squeezed downward under the action of the air pressure generated by the gas input, so that the bottom end of the locking plug 94 is plugged and locked to the bottom end of the float 6, thereby locking the rotation of the lower magnetic ring component 9, which can further control As the float 6 rises, the upper magnetic ring assembly 8 rotates around the upper center rod 4 to drive the lower magnetic ring assembly 9 to achieve further height control of the bottom mapping platform 21, and the injection of gas will also automatically unlock the internal structure of the suspension assembly 20 and the transmission rack assembly 17. After unlocking, the suspension assembly 20 can be clamped and engaged with the lower center rod 7. In this way, under the drive of the external drive motor 3, the lower center rod 7 is driven to rotate by the upper center rod 4, realizing the up and down movement of the suspension assembly 20 as a whole, and at the same time, the traction rope 13 set above the suspension assembly 20 is driven by the rotation drive of the upper internal motor 133. 5 for synchronous retraction and unwinding. Combined with the above height adjustment, the device can not only automatically adjust the height of the surveying and mapping platform 21 as the water level changes, but also realize secondary adjustment by replacing the driven gear 19 through the internal structural setting, and realize tertiary adjustment by driving the internal motor 133 to rotate. Under these three levels of adjustment, the height accuracy of the surveying and mapping platform 21 in water can be greatly controlled. In addition, the structural setting of the surveying and mapping device can avoid the use of traditional hydraulic telescopic rods in water and humid environments, greatly improving the overall structural reliability of the equipment and ensuring the service life of the equipment.

[0043] See also Figure 1-4 , an eco-hydrological surveying and mapping device for river basins, comprising an outer shell 1, the outer shell 1 being two semi-arc structures, and the ends of the two outer shells 1 being spaced apart, the outer shell 1 being fixedly mounted on an external platform, the limit block 10 being located at the space between the two outer shells 1 for limited sliding, and the straight groove 5 being located at the position where the side connecting rods 15 are located on both sides;

[0044] In this embodiment, it should be noted that when the water level of the water surface changes, the float 6 as a whole can utilize the floating effect to limit the up and down movement of the float 6 between the two outer shells 1, thereby preventing the float 6 from shaking, thereby ensuring the stability of the surveying and mapping platform 21 at the bottom, and the setting of the straight groove 5 is also to ensure that the transmission rack assembly 17 at the bottom can be unobstructed during the extension and contraction process, thereby ensuring the normal operation of the entire equipment.

[0045] See also Figure 1-3 An eco-hydrological surveying and mapping device for river basins includes an upper center rod 4, wherein both the upper center rod 4 and the lower center rod 7 are provided with a thread groove, and the pitch of the thread groove on the upper center rod 4 is much greater than the pitch of the thread groove on the lower center rod 7. An upper magnetic ring assembly 8 is limitedly sleeved on the thread groove of the upper center rod 4, and a lower magnetic ring assembly 9 is arranged to rotate and move inside a buoy 6;

[0046] In this embodiment, it should be noted that when the buoy 6 is affected by water level fluctuations, it can move up and down with the help of the upper magnetic ring assembly 8 when rotating on the upper center rod 4. This ensures that when the buoy 6 moves up, the upper magnetic ring assembly 8 can also move up and down synchronously, and can also drive the lower magnetic ring assembly 9 to rotate. In this way, the transmission rack assembly 17 is extended and retracted laterally through the driven gear 19 at the bottom, thereby driving the surveying and mapping platform 21 to move up and down, reflecting the linkage of the internal structure of the entire equipment.

[0048] In this embodiment, it should be noted that gas can be injected into the gas separation chamber 12 through the adjustment component 13, and then the gas is used to pressurize the adjustment component 13 so that it forms a force on the lower magnetic ring component 9. At the same time, combined with the elastic force of the first spring 14, the locking and unlocking switching of the lower magnetic ring component 9 can be controlled, thereby ensuring the subsequent accurate and effective position adjustment of the bottom mapping platform 21.

[0050] In this embodiment, it should be noted that the inner roller 83 is symmetrically arranged inside the center support 81 and is rotatably arranged in the threaded groove opened on the upper center rod 4. In this way, when the buoy 6 floats, the movement of the inner roller 83 in the threaded groove on the upper center rod 4 can be utilized to achieve up and down movement on the upper center rod 4, thereby ensuring that it can move with the floating of the buoy 6, and can synchronously drive the lower magnetic ring assembly 9 at the bottom to rotate synchronously, thereby adjusting the position of the bottom mapping platform 21.

The first oblique block 204 and the second oblique block 206 are structural arrangements with two oblique surfaces. The cross section of the first oblique block 204 is a right-angled trapezoid with the upper base length being shorter than the lower base length. The second oblique block 206 is arranged in the opposite manner. The third spring 207 is arranged between the vertical plate 205 and the inside of the straight tube 201. A plurality of small holes are evenly opened on the side of the straight tube 201, and the insertion rod 208 is movably inserted into the small holes for installation. The insertion rod 208 can be inserted into the clamp The locking hole opened inside the holding kit 177 is limited and locked. In this way, after the gas is injected into the top of the inner rod 203, the gas pressure is used to squeeze the inner rod 203 downward, thereby separating the top sealing plate of the inner rod 203 from the bottom end of the air inlet pipe 202, so that the gas can enter the straight tube 201. At the same time, the downward movement of the inner rod 203 will also cause the first inclined block 204 to slowly reduce the compression amount of the second inclined block 206, and finally realize the locking and empty withdrawal of the insertion rod 208 from the clamping kit 177, thereby unlocking the locking limit of the straight tube 201 and the clamping kit 177, so that the side clamping head 2010 can be used to clamp the lower center rod 7, and the rotation of the lower center rod 7 can be used to drive it to move up and down for height adjustment, and after the adjustment is completed, the air pressure is reduced and the inner rod 203 automatically moves upward under the elastic force of the fourth spring 2012 to squeeze the end of the insertion rod 208 into the locking hole of the clamping kit 177 again and lock it, ensuring that the height of the bottom surveying and mapping platform 21 is fixed.

[0059] See also Figure 11-15An eco-hydrological surveying and mapping device for a river basin includes a side extension structure 209, the side extension structure 209 includes an inner pipe 2091, an inner air bag 2092 is fixedly provided inside the inner pipe 2091, and an outer sliding pipe 2093 is movably sleeved on the outer portion of the inner pipe 2091;

[0060] In this embodiment, it should be noted that one end of the inner pipe 2091 is fixedly connected to the straight pipe 201, and the inner air bag 2092 and the outer sliding pipe 2093 are fixedly installed with a clamping head 2010 at one end away from the straight pipe 201. The inner air bag 2092 is made of elastic material, so that after the gas is injected into the inner air bag 2092, it can expand, thereby driving the outer sliding pipe 2093 to move laterally, and thus driving the clamping head 2010 to extend and retract, so that it can engage with the lower center rod 7, and then drive the suspension assembly 20 as a whole to move up and down through the rotation of the lower center rod 7, thereby realizing the up and down movement of the bottom mapping platform 21.

[0061] Working principle: when the water level changes, the buoy 6 will float, and the floating of the buoy 6 will cause the active magnetic ring 82 to rotate around the upper center rod 4 and move up and down at the same time, which will drive the driven magnetic ring 91 to rotate, and the driven magnetic ring 91 will drive the driven gear 19 to rotate, and the driven gear 19 will drive the transmission rack 174 to move telescopically, thereby causing the traction diagonal rod 176 to rotate around the bottom end of the side rod 175 under the lateral movement of the transmission rack 174, and adjust the upper and lower positions of the clamping kit 177 and the suspension assembly 20. When further adjustment is needed, gas can be injected into the gas separation chamber 12 by starting the air pump 131, thereby extending the telescopic air guide tube 136 and squeezing the locking plug 94 downward, thereby locking The bottom end of the plug-in 94 is inserted into the locking slot at the bottom end of the float 6 to lock the driven magnetic ring 91. At the same time, part of the gas from the air pump 131 is poured into the straight tube 201 through the gas pipe 132. The gas will squeeze the inner rod 203, thereby causing the first inclined block 204 to gradually break away from the squeezing of the second inclined block 206, thereby causing the insertion rods 208 on both sides to shrink in, releasing the locking relationship between the straight tube 201 and the clamping kit 177. In this way, the lower center rod 7 can be driven to rotate by the top external drive motor 3. Since the lower magnetic ring assembly 9 is locked, the lower magnetic ring assembly 9 will not rotate when the upper center rod 4 rotates to drive the upper magnetic ring assembly 8 to rotate. In this way, the rotation of the lower center rod 7 will drive the suspension assembly 20 to move up and down, thereby adjusting the immersion depth of the bottom mapping platform 21.
