DETAILED DESCRIPTION

[0030] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0031] Example 1

[0032] A buoyancy water lifting device for water conservancy and hydropower, such as Figure 1 and Figure 2 As shown, it includes a connecting frame 1, a reel motor 2, a connecting component 301, a water bucket 3, a sleeve 4, a buoyancy baffle 5, a first spring 6, a pull rope 7, a height adjustment mechanism 8 and a filtering and water-lifting mechanism 9. The upper sides of the left and right parts of the connecting frame 1 are both slidably connected to the reel motor 2, and the reel motor 2 has its own winding reel. The connecting frame 1 is slidably connected to the connecting component 301, and the connecting component 301 is rotatably connected to the water bucket 3. The water bucket 3 is used to hold water. The bottom of the water bucket 3 is connected to the sleeve 4, and the buoyancy baffle 5 is slidably connected in the sleeve 4. A first spring 6 is connected between the sleeve 4 and the buoyancy baffle 5, and the first spring 6 is wound on the buoyancy baffle 5. The first spring 6 plays a buffering and resetting role for the buoyancy baffle 5. A pull rope 7 is connected between the reel motor 2 and the connecting component 301. The connecting frame 1 is provided with a height adjustment mechanism 8 for adjusting the height, and the sleeve 4 is provided with a filtering and water-lifting mechanism 9 for filtering water.

[0033] like Figure 2 and Figure 3As shown, the height adjustment mechanism 8 includes a connecting bracket 81, a thread 82 and a first nut ring 83. The connecting bracket 1 is slidably connected to the connecting bracket 81, and the connecting bracket 81 guides the connecting bracket 1. The connecting bracket 1 is wound with a thread 82, and the top of the connecting bracket 81 is rotatably connected to a front-to-back symmetrical first nut ring 83, and the first nut ring 83 is threadedly connected to the thread 82.

[0034] like Figure 2 and Figure 4 As shown, the filtering and water-lifting mechanism 9 includes a filter plate 91, a dredging component 92 and a second spring 93. The filter plate 91 is connected to the bottom of the sleeve 4, and the filter plate 91 can filter the water flow. The dredging component 92 is slidably connected to the sleeve 4, and the dredging component 92 can dredge the filter plate 91. The dredging component 92 is connected to the buoyancy blocking plate 5. Three second springs 93 are connected between the dredging component 92 and the sleeve 4. The second springs 93 are all wound around the dredging component 92, and the second springs 93 all play a buffering and resetting role for the dredging component 92.

[0035] This device can salvage and extract water. When using this device, first rotate the first nut ring 83 according to the water level, so that under the cooperation of the first nut ring 83 and the thread line 82, the connecting frame 1 will start to move, so that the water bucket 3 can be close to the water surface. As the buoyancy plug 5 contacts the water surface, the buoyancy plug 5 will be pushed upward under the action of the water surface tension, so that the first spring 6 is compressed. At the same time, the buoyancy plug 5 will drive the dredging component 92 to slide upward, and the second spring 93 is also compressed. At this time, the water flow will pass through the filter plate 91 into the sleeve 4, and then into the water bucket 3. When the water in the water bucket 3 is loaded to a certain level, the reel motor 2 will start to operate automatically under preset conditions, thereby winding the pull rope 7, and the pull rope 7 will drive the connecting component 30 1 starts to slide upward, thereby making the water bucket 3 start to move upward. As the water bucket 3 leaves the water surface, under the action of the first spring 6, the buoyancy blocking plate 5 slides downward and resets. At the same time, under the action of the second spring 93, the dredging component 92 also slides downward and resets. When the dredging component 92 is reset, the filter holes on the filter plate 91 are dredged to prevent mud and sand accumulation and blockage. When the pull rope 7 pulls the connecting component 301 to a certain height, the reel motor 2 will automatically stop working. People can rotate the water bucket 3 to pour out the water. After pouring out, rotate the water bucket 3 to reset it. In summary, by rotating the first nut ring 83, the height of the device can be adjusted, so that the water bucket 3 can be close to the water surface. Thereafter, under the filtering action of the filter plate 91, the water flow is collected into the water bucket 3 to complete the collection.

[0036] Example 2

[0037] On the basis of Example 1, Figure 2 、 Figure 5 and Figure 6 As shown, it also includes a lifting and reinforcing mechanism 10, which includes a ring 101, a locking rod 102, a third spring 103, a fixed plate 104 and a rotating plate 105. The lower part of the connecting bracket 81 is connected to the ring 101, and the locking rod 102 is slidably connected to the ring 101. The third spring 103 is connected between the locking rod 102 and the ring 101. The third spring 103 is wound around the locking rod 102, and the third spring 103 has a buffering and resetting effect on the locking rod 102. The side of the lower part of the connecting bracket 81 that is away from each other is connected to the fixed plate 104, and the rotating plate 105 is rotatably connected to the fixed plate 104. The rotating plate 105 can be clamped with the adjacent locking rod 102, and the rotating plate 105 can improve the supporting stability of the connecting bracket 81.

[0038] As the height of the connecting frame 1 is adjusted, the overall height of the device will be higher, thereby causing the center of gravity of the device to move upward, and the placement will become more unstable. In order to improve the placement stability of the device, people can pull the locking rods 102 to the side close to each other, and the third springs 103 are compressed. At this time, the locking rods 102 are disengaged from the rotating plates 105, and people can rotate and unfold the rotating plates 105 to the side away from each other, so that the rotating plates 105 are in contact with the ground, thereby improving the placement stability of the connecting bracket 81. When the rotating plates 105 are in contact with the ground, the locking rods 102 are released, and under the action of the third springs 103, the locking rods 102 are When the reinforcing device is no longer needed, the locking rods 102 are pulled toward the side close to each other, and the third springs 103 are compressed. Then people can rotate and retract the rotating plates 105 toward the side close to each other, and then release the locking rods 102. Under the action of the third springs 103, the locking rods 102 slide and reset toward the side away from each other and engage with the rotating plates 105, thereby locking and fixing the rotating plates 105. In summary, by unfolding the rotating plates 105, the rotating plates 105 are in contact with the ground, which increases the ground contact area of ​​the connecting bracket 81 and enhances the supporting stability of the connecting bracket 81.

[0039] like Figure 2 、 Figure 7 and Figure 8 As shown, it also includes a transverse adjustment mechanism 11, which includes a connecting frame 1101, a second nut ring 1102 and a threaded rod 1103. The left and right parts of the connecting frame 1 are connected to the connecting frame 1101, and the bottom of the reel motor 2 is connected to the second nut ring 1102. The threaded rod 1103 is rotatably connected in the connecting frame 1101, and the threaded rod 1103 is threadedly connected to the second nut ring 1102. The threaded rod 1103 plays a guiding role for the second nut ring 1102.

[0040] When the device is placed and fixed, if there is a certain horizontal distance difference between the water bucket 3 and the water surface, people can rotate the threaded rod 1103 to make the second nut ring 1102 start to move, and then drive the belt reel motor 2 to start sliding, so that the water bucket 3 can move horizontally above the water surface, thereby facilitating water fetching. When the water fetching is completed, people can rotate the threaded rod 1103 in the opposite direction to make the second nut ring 1102 move and reset, and then drive the belt reel motor 2 to move and reset. In summary, by rotating the threaded rod 1103 to make the second nut ring 1102 move, the effect of adjusting the position of the belt reel motor 2 is achieved, so that the water bucket 3 can move above the water surface, thereby facilitating the water fetching operation.

[0041] like Figure 2 、 Figure 9 and Figure 10 As shown, it also includes an automatic pouring mechanism 12, which includes a rack 1201, a spur gear 1202, a guide rod 1203, a block 1204, a fourth spring 1205, a square block 1206 and a contact rod 1207. The front side of the top middle of the connecting frame 1 is connected to a left-right symmetrical rack 1201, and the left and right sides of the water bucket 3 are connected to spur gears 1202. The left spur gear 1202 can mesh with the left rack 1201, and the right spur gear 1202 can mesh with the right rack 1201. The bottom of the connecting assembly 301 is connected to a left-right symmetrical guide rod. 1203, a card block 1204 is slidably connected to the guide rod 1203, and the guide rod 1203 guides the card block 1204. The top of the card block 1204 is connected to a contact rod 1207, and the contact rod 1207 can contact the connecting frame 1. A fourth spring 1205 is connected between the card block 1204 and the guide rod 1203, and the fourth spring 1205 is wound around the guide rod 1203. The fourth spring 1205 has a buffering and resetting effect on the card block 1204. Square blocks 1206 are connected to the left and right sides of the water bucket 3, and the square blocks 1206 are clamped with the card block 1204.

[0042] As the pull rope 7 starts to pull the connecting assembly 301 upward, the connecting frame 1 will first push and squeeze the contact rod 1207, so that the contact rod 1207 drives the clamping block 1204 to slide downward, and the fourth spring 1205 is compressed. At this time, the clamping block 1204 is disengaged from the square block 1206, so that the spur gear 1202 is disengaged from the lock. When the spur gear 1202 starts to contact the rack 1201, the spur gear 1202 will start to rotate, so that the water bucket 3 starts to rotate, achieving the effect of automatically pouring out the water. As the connecting assembly 301 starts to move downward and reset, the connecting frame 1 no longer squeezes the contact rod 1207, and the spur gear 1202 starts to move downward. In this process, The rack 1201 will cause the spur gear 1202 to start rotating, thereby causing the water bucket 3 to rotate and reset. As the connecting component 301 continues to descend and reset, under the action of the fourth spring 1205, the block 1204 drives the contact rod 1207 to slide upward and reset, and engages with the square block 1206, so that the spur gear 1202 is locked and fixed. In summary, the connecting component 301 is driven to rise by the pull rope 7, so that the contact rod 1207 drives the block 1204 to slide downward, and the block 1204 is disengaged from the square block 1206. Afterwards, with the mutual cooperation of the rack 1201 and the spur gear 1202, the water bucket 3 can automatically rotate to pour out the water, thereby achieving the effect of automatic pouring.

[0043] like Figure 2 and Figure 11 As shown, it also includes a weighting mechanism 13, which includes a sleeve rod frame 1301, a sponge ring 1302, an extrusion ring 1303 and a fifth spring 1304. The sleeve rod frame 1301 is connected to the rear side of the water bucket 3, and the extrusion ring 1303 is slidably connected to the lower part of the sleeve rod frame 1301. A sponge ring 1302 is connected between the extrusion ring 1303 and the water bucket 3. The sponge ring 1302 can absorb water and increase weight. A fifth spring 1304 is connected between the extrusion ring 1303 and the sleeve rod frame 1301. The fifth springs 1304 are all wound around the sleeve rod frame 1301. The fifth springs 1304 all have a buffering and resetting effect on the extrusion ring 1303. There are two fifth springs 1304, which can improve the sliding stability of the extrusion ring 1303.

[0044] As the water bucket 3 enters the water, the sponge ring 1302 will begin to absorb water and increase its weight, so that the water bucket 3 can enter the water more stably without shaking. At the same time, as the water bucket 3 continues to enter the water, the squeezing ring 1303 will begin to slide upward, so that the fifth spring 1304 will be compressed, and the sponge ring 1302 will begin to be squeezed. The water in the sponge ring 1302 will gradually be squeezed out as the water in the water bucket 3 increases. When the water bucket 3 is full of water and leaves the water surface, the squeezing ring 1303 will no longer be squeezed. Under the action of the fifth spring 1304, the squeezing ring 1303 slides downward and resets, so that the sponge ring 1302 restores its shape. In summary, the sponge ring 1302 absorbs water to increase the weight of the water bucket 3, so that the water bucket 3 can enter the water smoothly, reducing the resistance of the water bucket 3 entering the water, and finally the water in the sponge ring 1302 is squeezed out by the squeezing ring 1303.
