Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of debris flow sand retaining dam, and particularly relates to a debris flow diversion and deposition retaining dam. BACKGROUND

[0002] In a debris flow prevention project, a sand retaining dam is an important facility widely used. The traditional sand retaining dam can to some extent play a role in retaining and storing sand, reducing flood peak and reducing debris flow speed.

[0003] The existing flood discharge channel of the sand retaining dam is mostly provided with multiple unblocking mechanisms for conveniently unblocking the sand and silt accumulated therein. However, the unblocking operation of the multiple unblocking mechanisms needs to be driven step by step, which is inconvenient. When the unblocking mechanism is subjected to a large accumulated resistance, synchronous driving of all the unblocking mechanisms is required to resist the strong accumulated resistance, which may make it difficult for the hand driving force to resist the strong accumulated resistance, so that the unblocking operation cannot be normally implemented. Although some existing flood discharge channels are provided with mechanisms for synchronously driving the unblocking mechanisms, these mechanisms cannot decouple the driving force of the unblocking mechanisms when the above situation occurs, so as to reduce the number of driving mechanisms, reduce the hand driving force required to resist the accumulated resistance, and ensure successful and effective unblocking operation under the above use condition. Thus, the existing unblocking mechanism cannot be applied to the high-efficiency operation condition of synchronous driving of all the mechanisms and the operation condition of reducing the number of synchronous driving mechanisms to reduce the accumulated resistance and ensure normal and effective unblocking operation, and cannot be compatible with different unblocking operation conditions, so the flexibility of operation and use is poor, and the practicability is poor.

[0050] Preferably, the dam body 1 is further provided with a row of flood discharge grooves 101 arranged in penetration, and a rectangular sunken groove 102 is formed at the top end of the water discharge side of the flood discharge grooves 101.

[0051] The rectangular holding frame 2 is preferably embedded and fixed in the spillway 101, and a horizontal support holding plate 202 is welded at the inner top end of the rectangular holding frame 2, which divides the inner space of the rectangular holding frame 2 into two cavities, and the L-shaped driving rod 4, the transmission swing rod 303, the synchronous transmission plate 5, the driving assembly 7 and the lead screw 701 are all arranged in the upper cavity, and the upper cavity is located in the rectangular sink 102.

[0054] The working principle, specific details, implementation steps, functions and mutual relationships of each feature, and the role played in the process of realizing the present application of the above-mentioned content are described and explained in detail as follows:

[0055] The transverse support retaining plate 202, the vertical retaining plate 201 and the row of dredging rollers 3 jointly form a retaining mechanism for retaining and stopping the silt and sand in the debris flow in the rectangular retaining frame 2. The dam body 1 and the row of retaining mechanisms are used in cooperation to retain and stop the silt and sand on the inner side of the dam body 1. The muddy water mixed in the debris flow is discharged through the vertical discharge channels formed in the rectangular retaining frame 2 in the row of discharge grooves 101. The two rows of dredging push rods 302 on the dredging roller 3 are positioned in the transverse support state and block the vertical discharge channels to serve as vertical retaining components for retaining and stopping the silt and sand. In use, the larger sand particles are retained against the rows of dredging push rods 302 on the row of dredging rollers 3. The vertical discharge channels discharge the muddy water through the support gaps formed between the retained sand particles. After a long time of silt accumulation, the support gaps can be gradually and completely blocked, losing the discharge function. The dredging roller 3 is installed in a rotating manner and is driven to rotate in the forward and reverse directions. The two rows of dredging push rods 302 on the dredging roller 3 can push and displace the sand particles retained on the rows of dredging push rods 302 to loosen and open the support gaps blocked by the silt between the sand particles, thereby restoring the discharge function of the support gaps and dredging the discharge grooves 101 and the vertical discharge channels. The dredging roller 3 can be used as a vertical retaining component and a dredging mechanism for dredging the discharge grooves 101, having a dual-purpose effect. The effect can simplify the structure of the sand retaining dam and reduce the cost.

[0056] When the row of transmission connecting pieces 304 are inserted into and rotate with the row of transmission swing rods 303, the row of transmission swing rods 303 and the synchronous transmission plate 5 jointly form a synchronous transmission mechanism. Under the synchronous transmission of the mechanism, the L-shaped drive rod 4 is driven to swing inward and outward, thereby driving the row of dredging rollers 3 to rotate in the forward and reverse directions to simultaneously dredge the row of discharge grooves 101. This can avoid the need to drive the row of dredging mechanisms step by step to dredge the row of discharge grooves 101, thereby improving the convenience and efficiency of operation. The L-shaped drive rod 4 has two driving modes, one of which is directly driven by the hand and the other of which is driven by the drive assembly 7. In the normal use state where the drive assembly 7 is not faulty, the L-shaped drive rod 4 is driven by the drive assembly 7. When the drive assembly 7 is faulty, the L-shaped drive rod 4 is directly driven by the hand. In this way, the dredging mechanism can be switched to the state of being driven by the hand when the drive assembly 7 is faulty, ensuring that the dredging mechanism can be driven by the hand to continuously perform the dredging operation, thereby improving the performance of the dredging mechanism in response to the fault of the drive assembly 7, expanding the fault tolerance of the dredging mechanism and enhancing the practicality of the dredging mechanism.

[0057] The threaded sleeve 702, the pull rod 405 and the L-shaped driving rod 4 jointly constitute a set of crank slider mechanism, through which the driving assembly 7 can push the threaded sleeve 702 to slide towards or away from the driving assembly 7 when the driving screw 701 rotates in the forward and reverse directions, control the inside and outside swing of the L-shaped driving rod 4, and drive a row of the clearing and unblocking mechanism to twist in the forward and reverse directions to implement the clearing and unblocking; the pull rod 405 and the L-shaped driving rod 4 are connected through the transmission assembly 6, and in the clearing and unblocking working condition of the clearing and unblocking mechanism driven manually, the transmission assembly 6 needs to be separated from the pull rod 405 and the L-shaped driving rod 4, so as to decouple the power of the driving assembly 7 and the L-shaped driving rod 4, and avoid the self-locking effect of the threaded engagement between the driving screw 701 and the threaded sleeve 702 to hinder the hand driving operation of the L-shaped driving rod 4. Through the design of the transmission assembly 6 that can decouple the power of the driving assembly 7 and the L-shaped driving rod 4, the clearing and unblocking mechanism can be compatible with the two driving operation forms of mechanical driving and hand driving.

[0058] When the sand and silt abutting against the jamming resistance on the several rows of unblocking rods 302 is large, the driving force output by the hand through the L-shaped driving rod 4 for synchronously twisting to drive a row of the unblocking roller frame 3 may be difficult to overcome the large jamming resistance, and the transmission connecting piece 304 adopts a sliding installation form, which can slide upward and separate from the corresponding position of the transmission swing rod 303 under the above condition, disconnect the power connection between the transmission swing rod 303 and the synchronous transmission plate 5, decouple the power of the unblocking roller frame 3 connected with the transmission swing rod 303 and the synchronous transmission plate 5, temporarily reduce the synchronous driving number of the synchronous transmission mechanism to the unblocking roller frame 3, reduce the jamming resistance that needs to be overcome by the hand when synchronously twisting to drive the unblocking roller frame 3, so that in the clearing and unblocking working condition with large jamming resistance, the jamming resistance that needs to be overcome by the hand can be indirectly reduced by reducing the synchronous driving number of the clearing and unblocking mechanism, which helps to ensure the normal and effective performance of the clearing and unblocking operation under the clearing and unblocking working condition. Through the design that the synchronous transmission mechanism can be decoupled with the unblocking roller frame 3, the clearing and unblocking mechanism can be suitable for the working condition that it is driven together synchronously and the working condition that the synchronous driving number is reduced to reduce the jamming resistance and ensure the normal performance of the clearing and unblocking operation, and can be compatible with different clearing and unblocking working conditions, which helps to improve the flexibility and practicality of the operation.

[0059] Similarly, in the clearing and unblocking working condition with large jamming resistance, the above operation can also be performed to reduce the load of the driving assembly 7 and reduce the probability of overloading and burning of the driving assembly 7, and implement overload protection for the driving assembly 7.

[0060] The locking bolt 3043 can position the transmission connecting piece 304 in the use state of being inserted and connected in transmission or being separated and disconnected with the transmission swing rod 303 and the synchronous transmission plate 5.

[0061] It is worth noting that: in the use condition of reducing the number of synchronous driving of the dredging roller frame 3 by disconnecting the transmission connection 304 and the transmission swing rod 303, at least two transmission connections 304 and two transmission swing rods 303 in the corresponding position should be kept in plug-in cooperation, which can ensure that the synchronous transmission plate 5 is at least in transmission connection with two transmission swing rods 303 and keeps in a stable transmission state parallel to the horizontal support retaining plate 202, ensuring that it can stably and effectively drive the dredging roller frame 3 with reduced number; among the two transmission connections 304 kept in plug-in transmission state, at least one should be in plug-in cooperation with the transmission swing rod 303 on the dredging roller frame 3 where the L-shaped driving rod 4 is located.

[0062] When the protruding part of the plug shaft 403 is inserted into the top part of the vertical side plate of the rectangular retaining frame 2, the L-shaped driving rod 4 can be positioned in the idle retracted state in the built-in rectangular sink 102. When the L-shaped driving rod 4 is in the idle retracted state, it is in a horizontal state, which can reduce the occupation of space and avoid collision injury to the staff or other idle personnel passing through the dam body 1. When the L-shaped driving rod 4 is positioned in the horizontal retracted state, the synchronous transmission plate 5 can be used to position the dredging roller frame 3, so that the two rows of dredging levers 302 on the dredging roller frame 3 are kept in the horizontal support interception state.

[0063] In the use condition of driving the L-shaped driving rod 4 by hand, the idle retracted state of the L-shaped driving rod 4 and the horizontal interception state of the two rows of dredging levers 302 are positioned by plug-in positioning of the plug shaft 403, and the plug shaft 403 is kept in the plug-in positioning state by the spring in the shaft hole 402. In the use condition of driving the L-shaped driving rod 4 by the driving assembly 7, the idle retracted state of the L-shaped driving rod 4 and the horizontal interception state of the two rows of dredging levers 302 are directly positioned by the self-locking effect generated by the threaded engagement of the driving screw 701 and the threaded sleeve 702. When the L-shaped driving rod 4 is driven by the driving assembly 7, the plug shaft 403 needs to be positioned in the state of being separated from the vertical side plate of the rectangular retaining frame 2, so as to release the positioning of the L-shaped driving rod 4, restore the free swing of the L-shaped driving rod 4, and provide the driving assembly 7 with unobstructed normal driving of the L-shaped driving rod 4. The jacking bolt 4022 can tightly fix the slip ring 404 and position the plug shaft 403. In the use condition of driving the L-shaped driving rod 4 by hand, the jacking bolt 4022 needs to be loosened to release the plug shaft 403.

[0064] When the unclogging roller frame 3 is driven to twist by the hand driving the L-shaped driving rod 4, the plug shaft 403 is separated from the vertical side plate of the rectangular retaining frame 2, the L-shaped driving rod 4 is loosened and turned out of the rectangular sink 102 to be placed in the unfolded state; the hand is held on the L-shaped driving rod 4 between the baffle disc 401 and the slip ring 404, and the L-shaped driving rod 4 is driven to turn in and out, and the plug shaft 403 is driven to plug and pull through the slip ring 404, so that the hand can hold the L-shaped driving rod 4 to turn in and out, and the plug shaft 403 is driven to slide in and out of the shaft hole 402 through the slip ring 404 to plug and pull the vertical side plate of the rectangular retaining frame 2, complete the plug-in locking and loosening unlocking of the L-shaped driving rod 4, and help improve the convenience and efficiency of the L-shaped driving rod 4.

[0065] The rectangular sink 102 has a blocking effect on sand and silt, through which all components hidden in the rectangular sink 102, especially the movable components and springs, can be prevented from being blocked and jammed by sand, which helps to ensure the long-term effective use of these components.

[0066] The L-shaped driving rod 4 is a torque driving force arm of the unclogging roller frame 3, the length of the force arm is equivalent to the width of the rectangular retaining frame 2, and has a certain length, the force arm with a certain length can amplify the hand holding output on the L-shaped driving rod 4 for torque driving the unclogging roller frame 3, so that the output driving force of the hand is sufficient to overcome the resistance in most unclogging working conditions, and successfully implement synchronous torque driving on all rows of unclogging roller frames 3.

[0067] It is worth noting that the drive assembly 7 drives the drive screw 701 in forward and reverse rotation, which is controlled by an automatic control system, and the composition and control principle of the automatic control system are prior art for those skilled in the art of equipment automation design, testing and modification, so it is not described here.

[0068] The above specific embodiments further illustrate the purpose, technical solutions and advantages of the present application, and it should be understood that the above is only a specific embodiment of the present application and does not limit the protection scope of the present application, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
