Description

Technical Field

[0001] This utility model relates to the field of dam cleaning technology, and in particular to an automatic dam cleaning device. Background Technology

[0002] A hydroelectric power plant, also known as a water power plant, is a factory that converts the potential and kinetic energy of water into electrical energy. Its basic production process is as follows: water is drawn from a high point in a river or other reservoir, and the pressure or velocity of the water drives a turbine to rotate, converting gravitational potential and kinetic energy into mechanical energy. The turbine then drives a generator to rotate, converting the mechanical energy into electrical energy. A power station generally consists of four main parts: a dam, spillway structures (spillways or gates), water intake structures (diversion channels or tunnels, including surge tanks), and the power plant building (including tailrace and booster station). The main components include hydraulic structures, hydraulic machinery, power generation equipment, transformer equipment, distribution equipment, transmission equipment, and control and auxiliary equipment. At the water intake of the dam, garbage and other debris often float on the water surface, requiring cleaning equipment to remove them.

[0003] In the published patent (CN213596938U A floating debris cleaning device for the intake of a hydropower station dam), floating debris is collected by using a conveyor belt with a strainer to drop it into a garbage collection bin. However, the garbage collection bin has limited space and must be emptied after it is full. However, the collection bin is fixed to the top of the cleaning vessel, which makes disassembly extremely inconvenient. Each cleaning requires a lot of manpower, resources and time, reducing the overall efficiency of the cleaning work. Therefore, we have introduced a new automatic dam cleaning device. Utility Model Content

[0004] The main purpose of this utility model is to provide an automatic dam cleaning device that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An automatic dam cleaning device includes a cleaning vessel. Limiting mechanisms are fixedly connected to the upper right front and upper right rear parts of the cleaning vessel. Two sluices are opened in the upper right middle part of the cleaning vessel, and a collection mechanism is slidably connected inside the two sluices. A water passage channel is opened in the upper left part of the cleaning vessel. A drive mechanism is installed on the upper left of the collection mechanism. A strainer conveyor belt is movably connected to the output end of the drive mechanism. A steering mechanism is movably connected to the lower left part of the cleaning vessel. A drive blade is movably connected to the right side of the cleaning vessel.

[0007] Preferably, the limiting mechanism includes a connecting block, a vertical plate is fixedly connected to the lower end of the connecting block, a movable groove is provided at the rear end of the connecting block, springs are fixedly connected to the left and right sides of the front groove wall of the movable groove, the rear ends of the two springs are jointly fixedly connected to the limiting block, a connecting rod is fixedly connected to the middle of the front end of the limiting block, and a pull ring is fixedly connected to the front end of the connecting rod.

[0008] Preferably, the lower end of the upright plate is fixedly connected to the hull of the cleaning vessel, and the limiting block is movably connected to the movable groove.

[0009] Preferably, the connecting rod is movably connected to the front wall of the movable groove, and the pull ring is located in front of the connecting block.

[0010] Preferably, the collection mechanism includes a garbage collection bin, with connecting handles fixedly connected to the upper front and upper rear of the garbage collection bin, and several drain pipes fixedly connected to the lower right end of the garbage collection bin. Limiting grooves are provided in the middle of the front and middle of the rear of the garbage collection bin, and pulleys are installed at the four corners of the lower end of the garbage collection bin.

[0011] Preferably, the lower part of the garbage collection bin is arranged with the left side higher than the right side, and several of the drain pipes are connected to the inside of the garbage collection bin.

[0012] Preferably, the two limiting grooves are respectively engaged with the two limiting blocks, and the two transverse pulleys are respectively slidably connected to the two sliding grooves.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. By setting a limiting mechanism, pulling two pull rings causes two limiting blocks to move into two movable slots via two connecting rods, compressing the springs. This places the pulleys at the bottom of the garbage collection bin into the two slots and slides them to the left. Releasing the pull rings causes the two limiting blocks to engage with the two limiting slots under the spring force. This allows the garbage collection bin to be easily and quickly installed on the cleaning vessel, improving the ease of installation and disassembly, making it easy and quick to replace, reducing the manpower and time costs required for cleaning, and improving the overall efficiency of the cleaning work.

[0015] 2. By setting up a collection mechanism, some water will remain on the surface of floating objects falling into the garbage collection bin through the strainer conveyor belt. This water will form a certain liquid level in the garbage collection bin, occupying part of the space. By designing the bottom of the garbage collection bin to be higher on the left and lower on the right, and by setting several drainage pipes on the lower right side of the garbage collection bin, the water inside the garbage collection bin can be discharged through several drainage pipes, thereby improving the space utilization rate inside the garbage collection bin.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] An automatic dam cleaning device includes a cleaning hull 1. Limiting mechanisms 2 are fixedly connected to the upper right front and upper right rear parts of the cleaning hull 1. Two sluices 3 are opened in the upper right middle part of the cleaning hull 1. A collection mechanism 4 is slidably connected inside the two sluices 3. A water passage trough 5 is opened in the upper left part of the cleaning hull 1. A drive mechanism 6 is installed on the upper left of the collection mechanism 4. A strainer conveyor belt 7 is movably connected to the output end of the drive mechanism 6. A steering mechanism 8 is movably connected to the lower left part of the cleaning hull 1. A drive blade 9 is movably connected to the right side of the cleaning hull 1.

[0026] In this embodiment, the limiting mechanism 2 includes a connecting block 21. A vertical plate 22 is fixedly connected to the lower end of the connecting block 21. A movable groove 23 is opened at the rear end of the connecting block 21. Springs 24 are fixedly connected to the left and right sides of the front groove wall of the movable groove 23. A limiting block 25 is fixedly connected to the rear ends of the two springs 24. A connecting rod 26 is fixedly connected to the middle of the front end of the limiting block 25. A pull ring 27 is fixedly connected to the front end of the connecting rod 26. The lower end of the vertical plate 22 is fixedly connected to the cleaning hull 1. The limiting block 25 and the movable groove 23 are interpenetratingly connected. The connecting rod 26 and the front groove wall of the movable groove 23 are interpenetratingly connected. The pull ring 27 is located in front of the connecting block 21.

[0027] The above solution involves pulling two pull rings 27, which, via two connecting rods 26, move two limiting blocks 25 into two movable slots 23, compressing the springs 24. This causes the pulleys 45 at the bottom of the garbage collection bin 41 to be inserted into the two sliding grooves 3 and slide to the left. Releasing the pull rings 27 causes the two limiting blocks 25 to be engaged into the two limiting slots 44 under the spring force of the springs 24, thus enabling the garbage collection bin 41 to be easily and quickly installed on the cleaning hull 1.

[0028] In this embodiment, the collection mechanism 4 includes a garbage collection bin 41. A connecting handle 42 is fixedly connected to the upper front part and the upper rear part of the garbage collection bin 41. Several drain pipes 43 are fixedly connected to the lower right part of the garbage collection bin 41. Limiting grooves 44 are opened in the middle of the front and the middle of the rear of the garbage collection bin 41. Pulleys 45 are installed at the four corners of the lower end of the garbage collection bin 41. The lower part of the garbage collection bin 41 is set with the left side higher than the right side. Several drain pipes 43 are connected to the inside of the garbage collection bin 41. The two limiting grooves 44 are respectively engaged with two limiting blocks 25. The two transverse pulleys 45 are respectively slidably connected to two sliding grooves 3.

[0029] With the above solution: some water will remain on the surface of the floating objects that fall into the garbage collection bin 41 through the strainer conveyor belt 7. This water will form a certain liquid level in the garbage collection bin 41, occupying part of the space of the garbage collection bin 41. By designing the bottom of the garbage collection bin 41 to be higher on the left and lower on the right, and by setting several drain pipes 43 on the lower right side of the garbage collection bin 41, the water inside the garbage collection bin 41 can be discharged through several drain pipes 43, thereby improving the space utilization rate inside the garbage collection bin 41.

[0030] It should be noted that this utility model is an automatic dam cleaning device. During use, by pulling a pair of pull rings 27, these two pull rings 27 respectively pull two limiting blocks 25 into two movable slots 23 via two connecting rods 26. During this process, the spring 24 is compressed. Subsequently, the pulley 45 at the bottom of the garbage collection box 41 is placed in the two sliding grooves 3 and slid to the left for installation. Once the pull rings 27 are released, the two limiting blocks 25 automatically reset under the elastic force of the spring 24 and respectively lock into the two limiting slots 44. This achieves convenient and quick installation and removal of the garbage collection box 41 on the cleaning hull 1, improving efficiency. The convenience of replacing the garbage collection bin 41 reduces the manpower and time costs required during the cleaning process, thereby improving the overall cleaning efficiency. In addition, considering that floating objects falling into the garbage collection bin 41 through the strainer conveyor belt 7 may have residual water on their surface, which will accumulate to a certain level inside the garbage collection bin 41 and occupy its internal space, the bottom of the garbage collection bin 41 is designed as a sloping structure with the left side higher than the right side, and multiple drain pipes 43 are configured on the lower right side. In this way, the water inside the garbage collection bin 41 can be smoothly discharged through these drain pipes 43, thereby improving the space utilization rate inside the garbage collection bin 41.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
