Description

Technical Field

[0001] The present invention relates to the field of water conservancy engineering equipment, in particular to a hydrological environment management device used in water conservancy engineering. Background Art

[0002] Water conservancy projects refer to various projects aimed at waterlogging control, flood prevention, irrigation, water supply, power generation, and water environment management, including their supporting and ancillary projects. In recent years, with the continuous improvement of environmental protection requirements, hydrological environmental management has received increasing attention and development. Hydrology encompasses both natural and artificial waters. Hydrological management of natural waters primarily focuses on ensuring pollution-free water bodies and a stable ecosystem. Artificial waters, on the other hand, must meet not only the hydrological requirements of natural waters but also aesthetic requirements. Therefore, excess algae and weeds within artificial waters, as well as those that affect the aesthetics of small or multi-regional areas, need to be cleared.

[0003] At present, the salvaging equipment for aquatic plants and algae generally has the application number: 201910464718.9, and the patent name is: A water plant salvaging device, the main body of which is a salvaging ship, and the salvaging ship is equipped with a conveying and harvesting device placed in the water body. The water plants in the water body are salvaged into the ship body through the conveying and harvesting device for collection. This type of equipment is a large-scale salvaging equipment, which is designed for environments with a lot of aquatic plants. It has high operating costs and high costs, and is not suitable for the salvage of small floating aquatic plants in artificial waters. In the prior art, there is also a device with application number: 202010319238.6 and patent name: Water Weed Salvage Device. The device is a handheld device with a simple structure. It mainly addresses the problem of water weeds sticking to the device. However, the most common thing in artificial waters that easily affects the appearance is floating algae. Taking water cotton as an example, it has a wide range of growth and exists in a clump-like floating state. It grows rapidly during the outbreak period. When salvaging this type of algae, using a salvage boat is obviously a waste of talent. Therefore, at this stage, when salvaging such debris, manually driven small boats are mostly used to salvage through scoop nets. There are several disadvantages in the scoop net salvage process. First, when the scoop net scoops up the water weeds, it does not control the water and is placed directly on the boat. The algae contain a lot of water. The untreated algae not only occupies a large area but also the water contained in it will quickly fill the cabin. In addition, due to the high water content and weight during the salvage process, the labor intensity of the workers will be high. Second, the salvage range of the scoop net is small. Taking water cotton as an example, if the scoop net diameter cannot cover the clumps of algae at one time, it is very difficult to scoop up the algae, and there are many inconveniences in dumping the algae scooped up by the scoop net. The dumping operation is complicated and time-consuming and labor-intensive. Therefore, in order to improve the above problems, some people use forks for salvage, but because the fork tines are widely spaced, it is not conducive to the effective salvage of aquatic plants. Therefore, at this stage, there is an urgent need for a professional equipment to solve the above problems. Summary of the Invention

[0019] The specific embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

[0020] Depend on Figures 1 to 4It can be seen that the present invention includes a scissor-type telescopic mechanism 1, which includes an odd number of scissor-type units. The hinge shaft in the middle of each scissor-type unit is a hollow shaft 2. The rear end of the hollow shaft 2 except the middle position of the telescopic mechanism 1 is coaxially mounted with a round tube 3. One side of the round tube 3 is provided with two groups of serrated blades 4. The two groups of blades 4 fit together, one group of blades 4 is fixed, and the other group of blades 4 can move back and forth along the main line direction of the round tube 3. A baffle 5 is provided on the other side of the round tube 3, and a pull rope 6 is fixed on the baffle 5. The free end of the pull rope 6 is fixed on the hollow shaft 2 adjacent to it and close to the middle position. The front end of the round tube 3 at the left and right ends is respectively provided with a baffle rod 7. A round tube 3 is coaxially fixed on the hollow shaft 2 in the middle position of the telescopic mechanism 1. The circular tube 3 in the middle position contains a blade 4 that is the same as that on the other circular tubes 3, and the tip of the blade 4 is facing upward, but does not contain a baffle 5. A handle 8 is coaxially fixed to the front end of the hollow shaft 2 in the middle position of the telescopic mechanism 1, and an electric cylinder 9 is installed on the handle 8. The protruding end of the electric cylinder 9 is hinged to two connecting rods 10 that are opened in an inverted V shape. The free ends of the two connecting rods 10 are respectively hinged to the two upper ends of the scissors-type unit in the middle position. When the electric cylinder 9 controls the telescopic mechanism 1 to extend, the pull rope 6 is subjected to force and the baffle 5 is driven into a horizontal state. When the telescopic mechanism 1 retracts, under the action of gravity and the limiting action of the baffle rod 7, the baffle 5 tends to be vertical. A sleeve 11 that can slide back and forth is mounted on the handle 8. The back and forth movement of the sleeve 11 can drive the movable blades 4 on all circular tubes 3 to move back and forth.

[0021] In order to facilitate the use of the circular tube 3, the rear end of the circular tube 3 is closed and has a pointed end.

[0022] In order to achieve the installation and reset of the movable blade 4, a polished rod 12 that can move along its axis is coaxially fixed in the circular tube 3. The front end of the polished rod 12 extends out of the hollow shaft 2. A through groove 13 is provided along the length direction of the circular tube 3. The movable blade 4 is installed on the polished rod 12 through the through groove 13. The front end of the circular tube 3 is provided with a first spring 14 that can reset the polished rod 12 backward.

[0023] In order to realize the forward and backward movement of the sleeve 11 and the driving of the movable blade 4, a horizontal pressure rod 15 is provided on each side of the left and right sides of the sleeve 11. The pressure rod 15 can cover the front end portions of all the light rods 12 except the middle position of the telescopic mechanism 1 in the retracted state. A U-shaped rod 16 is provided at the rear end of the sleeve 11. One end of the U-shaped rod 16 is fixed on the sleeve 11, and the other end is fixed to the light rod 12 in the middle position. A mounting groove for connecting the U-shaped rod 16 is provided on the hollow shaft 2 in the middle position.

[0024] In order to achieve the reset limit of the sleeve 11, a second spring 17 is provided between the rear end of the sleeve 11 and the hollow shaft 2 in the middle position. One end of the second spring 17 is fixed to the rear end of the sleeve 11, and the other end is fixed to the hollow shaft 2 in the middle position.

[0025] In order to realize the installation and drive of the electric cylinder 9, a mounting seat of the electric cylinder 9 is provided on the hollow shaft 2 in the middle position. The electric cylinder 9 is hinged to the connecting rod 10 via an L-shaped rod, and a battery 18 for the electric cylinder 9 is provided at the front end of the handle 8.

[0026] In order to achieve the water filtering performance of the baffle 5, the baffle 5 is densely covered with water-permeable holes.

[0027] In order to achieve auxiliary positioning of the telescopic mechanism 1, a horizontal and retractable slide rail 19 is provided on each side of the left and right sides of the hollow shaft 2 in the middle position, and the lower parts of the two adjacent hollow shafts 2 in the middle position are connected to the slide rail 19 through a slider.

[0028] In order to facilitate the grip of the sleeve 11 when sliding and to ensure that it can only slide and not rotate, the sleeve 11 and the handle 8 are connected via a limiting groove and a limiting block, and the ends of the sleeve 11 and the handle 8 are both covered with anti-slip rubber sleeves.

[0029] The specific working process of the present invention is as follows: when the device is in use, a worker drives a small boat to a place where there are clumps of floating algae in the water, and controls the electric cylinder 9 to realize the extension and contraction of the telescopic mechanism 1. When salvaging, the electric cylinder 9 is first controlled to retract. When the electric cylinder 9 retracts, the entire telescopic mechanism 1 is driven to extend via the connecting rod 10. At this time, the extension of the telescopic mechanism 1 causes the interval between the circular tubes 3 to increase. At this time, the pull rope 6 is stretched. During the extension of the telescopic mechanism 1, the baffle 5 is driven by the pull rope 6 to gradually tend to a horizontal state. At this time, multiple circular tubes 3 of the device can be placed from the bottom of the water and the clumps of algae can be salvaged. After the algae are salvaged, the electric cylinder 9 is controlled to extend. The extension of the electric cylinder 9 causes the electric cylinder 9 to drive the telescopic mechanism 1 to retract via the connecting rod 10. At this time, multiple circular tubes 3 move closer to the middle. In this process, the pull rope 6 is gradually loosened. Under the action of the gravity of the baffle 5, the baffle 5 gradually tends to a vertical state. At the same time, multiple circular tubes 3 are pulled together. The picked-up algae gradually changes from a horizontal mass to a wavy shape in the process of the circular tube 3 gathering toward the middle. As the electric cylinder 9 continues to shrink until the baffle 7 contacts and squeezes the scissor units at the left and right ends, the baffle 5 squeezes the wavy algae in a vertical state to control the water. After completion, the sleeve 11 is moved to drive the light rod 12 to move through the U-shaped rod 16 and the pressure rod 15. The movement of the light rod 12 can drive the movable blade 4 to move backward. The two sets of baffles that fit each other will cut the algae scraped on the outside of the circular tube 3. Under the reset action of the first spring 14 and the second spring 17, the blade 4 can repeatedly shear the algae. After completion, the algae that has been salvaged and controlled by the device is placed in the cabin. When placing, it is only necessary to control the inductive retraction and telescopic mechanism 1 to expand, and the squeezed water plants can be easily released. Then the expanded device can be put into the algae salvage operation again.

[0030] Compared with traditional equipment, this device has the following advantages:

[0031] 1. During the algae salvaging process of this device, the telescopic mechanism 1 is extended and the baffle 5 tends to be horizontal. At this time, the intervals between the circular tubes 3 are increased. Without the auxiliary extension of the baffle 5, the circular tubes 3 alone cannot support the salvaging of the algae. Under the extension of the baffle 5, the salvage area can be increased and the problem of the algae being unable to be lifted due to the small supporting point during the salvage process can be solved.

[0032] 2. The baffle 5 is vertical when the telescopic mechanism 1 retracts. During this process, the flat clumping algae are transformed into a wavy shape when the telescopic mechanism 1 contracts. The baffle 5 is used to squeeze and control the wavy algae through the limit rod during the contraction process, so that the water control of the algae can be achieved in one step after the salvage is completed, which is convenient for the carrying of the small boat and the subsequent packaging and dumping of the algae garbage.

[0033] 3. The movable sleeve 11 drives the two sets of mutually fitting serrated blades 4 to engage with each other, so that when the whole piece of waterweed cannot be salvaged at one time, the waterweed can be divided into pieces first and then salvaged in batches, which increases convenience and operability compared to traditional scoop nets.
