Description

Technical Field

[0001] The present invention relates to the technical field of fishway construction, and particularly relates to a mechanical device for constructing fishways in plateau areas. Background Art

[0002] A fishway is an artificial or natural passage designed to help fish overcome the migration obstacles caused by hydraulic engineering structures (such as dams and sluices), ensuring the smooth completion of life activities such as reproduction and foraging. A fishway is an artificial remedial measure taken to address the damage to the fish migration path caused by human activities (such as building dams). By designing specific structures (such as flumes, fish ladders, fish elevators, etc.) in hydraulic structures, it helps fish bypass the obstacles and maintain ecological connectivity. A fishway generally includes an inlet, a trough body, an outlet, and a fish attracting and makeup water system. For example, the fish attracting system utilizes the upstream swimming habit of fish and guides fish into the fishway through water flow, light, electric current, or even chemical stimuli.

[0003] The trapezoidal trough of a fishway is a facility used to guide fish migration or control water flow, and the pouring material at its top is crucial, requiring characteristics such as stable material performance, long service life, and high compressive strength. Concrete pouring is a common practice in fishway construction mainly because concrete has high strength and durability, can effectively prevent leakage and erosion, and ensure the stability and service life of the fishway.

[0004] For example, the utility model patent with the authorization announcement number CN220666227U and the patent name of a mobile concrete pouring device for narrow grooves includes tracks arranged on both sides of the narrow groove. A hopper is slidably arranged on the tracks. The lower end of the hopper is provided with a material guiding port, and a starting and closing door is arranged at the bottom of the material guiding port. The starting and closing door is driven by a first cylinder to open or close; the lower end of the material guiding port is directly opposite to the narrow groove; an extension pipe is arranged in the material guiding port. The upper end of the extension pipe is provided with an upper limit ring, and the bottom end of the material guiding port is provided with a lower limit ring; when the upper limit ring moves to the lower extreme position, it is restricted by the lower limit ring. The mobile concrete pouring device for narrow grooves provided by the present utility model can avoid concrete splashing.

[0005] This utility model slides the hopper on the tracks on both sides of the narrow groove, and can directly push the hopper while discharging materials to complete linear motion and pouring. Compared with traction by traction equipment, it is more simple and reliable to operate. In addition, by adopting a starting and closing door and a first cylinder at the material guiding port, it can be opened and closed at any time; thus, when pouring at one narrow groove is completed and there is still some concrete left in the hopper, the material guiding port can be closed and transferred to the next place for pouring, improving flexibility. At the same time, by sleeving an extension pipe in the material guiding port, and the extension pipe almost reaches the ground after extending, this can make the concrete directly and accurately fall into the narrow groove, avoiding splashing.

[0006] However, this patent cannot lay and compact the concrete mortar on the inner wall of the fishway groove. Manual formwork support and concrete pouring are still required, which not only has low efficiency but also increases labor costs, and there are certain defects.

[0007] In view of this, the present application is specifically proposed. Summary of the Invention

[0046] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present invention can be more thoroughly understood and the scope of the present invention can be fully conveyed to those skilled in the art.

[0047] As Figures 1 to 6 shown, an embodiment of the present invention provides a mechanical device for constructing a fishway in a plateau area, including:

[0048] A guide rail 1, the guide rail 1 is laid on the ground to be installed, and the guide rail 1 is arranged along the fishway trench 24.

[0049] A grouting bin 2, the grouting bin 2 is movably arranged on the guide rail 1, and the grouting bin 2 is used for laying concrete slurry on the inner wall of the fishway trench 24.

[0050] A driving member 3, the driving member 3 is installed on the grouting bin 2, and the driving member 3 is in transmission connection with the guide rail 1, and the driving member 3 is used for driving the grouting bin 2 to move along the guide rail 1;

[0051] A compaction member 4, the compaction member 4 is installed at the tail of the grouting bin 2, and the compaction member 4 is used for compacting and leveling the concrete slurry laid on the fishway trench 24.

[0052] In this embodiment, when it is necessary to lay concrete slurry on the inner wall of the fishway trench 24, first, the concrete slurry is put into the fishway trench 24, and the height of the concrete slurry is close to the depth of the fishway trench 24. Then, the driving member 3 is turned on. Under the drive of the driving member 3, the grouting bin 2 moves along the guide rail 1 and lays the concrete slurry located in the fishway trench 24 on the inner wall of the fishway trench 24 to complete the preliminary laying of the concrete slurry. Finally, the compaction member 4 compacts and levels the concrete slurry laid on the inner wall of the fishway trench 24 through reciprocating lifting motion to complete the construction work of the fishway trench 24.

[0053] Different from the prior art, this solution can automatically lay the concrete slurry located in the fishway trench 24 on the inner wall of the fishway trench 24 along the direction of the fishway trench 24, which can not only save labor costs, but also greatly improve the construction efficiency of the fishway trench 24. In addition, the adhesion between the concrete slurry laid on the surface of the fishway trench 24 and the inner wall of the fishway trench 24 is insufficient. By using the compaction member 4 to compact and level the concrete slurry laid on the inner wall of the fishway trench 24, not only the bonding force between the concrete slurry and the inner wall of the fishway trench 24 can be improved, but also the flatness of the surface of the concrete slurry can be improved.

[0054] It should be noted that the guide rail 1 is laid on the ground to be installed, and the guide rail 1 is in close contact and sliding contact with the outer surface of the grouting bin 2. When laying the concrete slurry, the flatness of the top edge of the fishway groove 24 can be ensured.

[0055] Furthermore, the grouting bin 2 includes:

[0056] A bin body 5, the bin body 5 is arranged in a frustum shape, and there is a grouting gap 6 between the bin body 5 and the inner wall of the fishway groove 24.

[0057] Moving wheels 7, there are two pairs of the moving wheels 7, and the two pairs of the moving wheels 7 are rotatably installed in the mounting holes through mounting rotating shafts 8, and a limit nut 9 is installed at one end of the mounting rotating shaft 8 away from the moving wheels 7.

[0058] In this embodiment, the size of the bin body 5 is determined according to the depth and width of the fishway groove 24. During the construction of the fishway groove 24, when the bin body 5 moves along the guide rail 1 and within the fishway groove 24, and the trapezoidal cross-section of the frustum faces the moving direction of the bin body 5 (i.e., the cross-section of the fishway groove 24 is trapezoidal), the concrete slurry is pushed by the bin body 5 into the grouting gap 6, and the concrete slurry is preliminarily laid on the inner wall of the fishway groove 24 to complete the laying operation of the concrete slurry.

[0059] In a specific embodiment, the bin body 5 is fixedly provided with a guiding block 10, the guiding block 10 is arranged in a quadrangular prism shape, and the guiding block 10 is located on the advancing side of the bin body 5. The guiding block 10 is arranged in a quadrangular pyramid shape, and the tip of the quadrangular pyramid faces the advancing side of the bin body 5. During the advancing process of the bin body 5, the quadrangular pyramid can penetrate the concrete slurry, reducing the advancing resistance of the bin body 5. In addition, the quadrangular pyramid-shaped guiding block 10 can disperse the concrete slurry and cooperate with the bin body 5 to realize the laying operation of the concrete slurry.

[0060] Furthermore, the driving member 3 includes:

[0061] A rotating shaft 11, the rotating shaft 11 is rotatably installed on the bin body 5.

[0062] A driving motor 12, the driving motor 12 is fixedly installed inside the bin body 5, and the driving motor 12 is in transmission connection with the rotating shaft 11.

[0063] Driving gears 13, the driving gears 13 are fixedly installed at both ends of the rotating shaft 11.

[0064] A transmission rack 14, the transmission rack 14 is fixedly arranged on the guide rail 1, and the transmission rack 14 is meshed and connected with the driving gears 13.

[0065] In this embodiment, driven by the driving motor 12, the rotating shaft 11 and the driving gear 13 rotate together with the driving motor 12, and then the driving gear 13 moves along the length direction of the transmission rack 14, thereby driving the warehouse body 5 to move along the fishway groove 24, and cooperate with the compacting member 4 to complete the concrete slurry laying and compacting operation of the fishway groove 24.

[0066] In a specific embodiment, the driving motor 12 is connected to the rotating shaft 11 through a worm gear, and the worm gear includes a driving worm 15, which is driven by the driving motor 12, and a driving worm wheel 16, which is fixedly mounted on the middle part of the rotating shaft 11, and the driving worm wheel 16 is meshedly connected with the driving worm 15.

[0067] The realization of worm gear self-locking mainly depends on the helix angle of the driving worm 15 and the friction coefficient between the worm gear. When the helix angle of the driving worm 15 is smaller than the friction angle between the worm gear, the worm gear mechanism has self-locking properties. This is because during the transmission process, the helical surface of the driving worm 15 will generate normal pressure on the transmission worm wheel 16, thereby generating friction. When the helix angle of the worm is smaller than the friction angle, the friction force will prevent the worm wheel from reversing, thereby achieving self-locking. By utilizing the self-locking of the worm gear, the bin body 5 can be kept stable in a certain position when the drive motor 12 stops working.

[0068] Wherein, the drive motor 12 adopts a servo motor. A servo motor refers to an engine that controls the operation of mechanical elements in a servo system, and is an auxiliary motor indirect speed change device. The servo motor can control the speed, and the position accuracy is very accurate. It can convert the voltage signal into torque and speed to drive the control object. The rotor speed of the servo motor is controlled by the input signal and can respond quickly. In the automatic control system, it is used as an actuator, and has the characteristics of small electromechanical time constant and high linearity. It can convert the received electrical signal into angular displacement or angular velocity output on the motor shaft. It is divided into two categories: DC and AC servo motors. Its main characteristics are that there is no self-rotation when the signal voltage is zero, and the speed decreases uniformly with the increase of torque. The drive motor 12 adopts a servo motor, which can accurately control the moving speed and moving distance of the warehouse body 5, thereby realizing the automated construction operation of the fishway groove 24.

[0069] Furthermore, the compacting member 4 comprises:

[0070] The mounting frame 17 is fixedly mounted on the sizing bin 2 .

[0071] The compaction plate 18 is vertically and movably installed on the mounting frame 17 through a transmission column 28. The transmission column 28 is vertically and movably installed on the mounting frame 17 through a linear bearing 23. The compaction plate 18 compacts and flattens the inner wall of the fishway trench 24 through up-and-down ramming. The cross-section of the compaction plate 18 matches that of the fishway trench 24.

[0072] A compaction motor 19 is fixedly installed in the sizing bin 2. An eccentric wheel 29 is fixedly installed on the output shaft of the compaction motor 19, and the eccentric wheel 29 is movably connected to the transmission column 28 through a transmission rod 25.

[0073] In this embodiment, driven by the compaction motor 19, the eccentric wheel 29 rotates together with the driving motor 12, and then drives the compaction plate 18 to perform a reciprocating lifting motion through the transmission rod 25. During the reciprocating lifting process of the compaction plate 18, the compaction plate 18 reciprocally compacts and flattens the concrete slurry laid on the inner wall of the fishway trench 24, which not only improves the adhesion between the concrete slurry and the inner wall of the fishway trench 24, but also ensures the flatness of the surface of the concrete slurry.

[0074] In a specific embodiment, a first connecting column 20 and a second connecting column 21 are respectively arranged on the eccentric wheel 29 and the transmission column 28, and both ends of the transmission rod 25 are movably connected to the first connecting column 20 and the connecting column respectively. The first connecting column 20 deviates from the center position of the eccentric wheel 29. During the rotation of the eccentric wheel 29, its circular motion is converted into the vertical motion of the compaction plate 18, and then the concrete slurry on the inner wall of the fishway trench 24 is compacted and flattened through the reciprocating lifting motion of the compaction plate 18.

[0075] Among them, the compaction motor 19 can adopt a servo motor. The servo motor can control the speed and can convert the voltage signal into torque and rotational speed to drive and control the object. By controlling the rotational speed of the compaction motor 19, the lifting frequency of the compaction plate is adjusted, thereby improving the construction quality of the fishway trench.

[0076] Furthermore, a plurality of adjustment holes 22 are arranged in the radial direction of the eccentric wheel 29. The adjustment holes 22 are evenly distributed on the eccentric wheel 29, and the first connecting column 20 is detachably installed in the adjustment holes 22.

[0077] In this embodiment, the first connecting column 20 can be threadedly installed in the corresponding adjustment hole 22. When the adjustment hole 22 where the first connecting column 20 is installed is close to the center position of the eccentric wheel 29, the reciprocating lifting amplitude of the compaction plate 18 decreases. When the adjustment hole 22 where the first connecting column 20 is installed is far from the center position of the eccentric wheel 29, the reciprocating lifting amplitude of the compaction plate 18 increases. The selection of the adjustment hole 22 can be made according to the compaction degree of the concrete on the inner wall of the fishway trench 24.

[0078] It should be noted that the silo body 5 and the mechanical structure located inside the silo body 5 itself have a certain weight. When the compaction plate 18 compacts the concrete laid on the inner wall of the fishway groove 24, the silo body 5 will not be lifted, ensuring the stable operation of the overall equipment.

[0079] In addition, the compaction plate 18 includes a bottom plate 26 and inclined plates 27 fixedly arranged at both ends of the bottom plate 26. Among them, the length of the inclined plate 27 is greater than the length of the inclined surface of the fishway groove 24. During the compaction process of the compaction plate 18, the inclined plate 27 is exposed outside the fishway groove 24 to ensure that the fishway groove 24 can be fully compacted.

[0080] Working principle: First, the concrete slurry to be laid on the inner wall of the fishway groove 24 is evenly poured into the fishway groove 24 so as to lay the concrete slurry on the inner wall of the fishway groove 24. Then, the driving motor 12 is turned on. Driven by the driving motor 12, the silo body 5 moves along the fishway groove 24, and the guiding block 10 disperses the concrete slurry on the side wall and bottom surface of the fishway groove 24. During the movement of the silo body 5, the concrete slurry enters the grouting gap 6, and the concrete slurry is laid on the inner wall of the fishway groove 24. Finally, the compaction member 4 drives the compaction member 4 to make a reciprocating lifting motion under the drive of the compaction motor 19, and drives the compaction member 4 to reciprocally compact and level the concrete slurry laid on the inner wall of the fishway groove 24, completing the laying and compaction operation of the concrete slurry in the fishway groove 24.

[0081] The above is the preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle described in the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
