Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of river bank protection, in particular to a protection device and method for canal channel bank protection. BACKGROUND

[0002] The protection device is a device for protecting the bank in the canal channel regulation project. In the process of channel maintenance, it is necessary to resist water impact to stabilize the bank. After the bank is stabilized, the safety of the navigation channel is ensured to avoid bank collapse and block the channel, and at the same time, the ecological environment around the channel is stable for the surrounding residents.

[0003] In the process of canal channel regulation, bank protection is a key link, which directly affects the navigation capacity of the channel and the safety of the surrounding environment. However, in actual situations, due to the operation of ships, water impact on both banks will occur, and bottles and impurities in the river will be time-consuming and laborious to salvage. A large number of bottles and impurities are accumulated on both sides of the channel. These bottles and impurities accumulated on the bank will affect the neatness of the bank. More importantly, bottles will be impacted and hit on the bank slope with river water impact. This impact will continuously wear the bank protection device and reduce the service life of the protection device. At the same time, it may also cause impact damage to the bank protection structure, thereby affecting the stability of the bank. Based on this, the present application provides a protection device and method for canal channel bank protection, which can reduce the impact of bottles and impurities on the bank and improve the protection effect of the bank protection.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0032] Please refer to Figures 1-5 The present application is a kind of protective device for canal channel bank protection, which comprises:

[0033] The protective shell 3 is fixedly installed on the slope protection 1 by the L-shaped plate 2, and a plurality of protective shells 3 are arranged at equal intervals along the direction of the slope protection 1. The fixing frame 7 is fixedly installed in the protective shell 3. The bidirectional screw rod 8 is rotatably installed on the fixing frame 7 and is driven to rotate by the transmission assembly. The bidirectional screw rod 8 is arranged along the direction of the water flow. The sliding rod 9 is slidably installed on the fixing frame 7 and is threadedly connected with the bidirectional screw rod 8. The storage cylinder 4 is arranged at the bottom end of the sliding rod 9 and is close to the slope protection 1. The annular cylinder 5 is fixedly installed in the storage cylinder 4. The lowest horizontal height of the annular cylinder 5 is lower than the water level at the slope protection 1, and the highest horizontal height of the annular cylinder 5 is higher than the water level at the slope protection 1. The flexible check bars 6 are fixedly connected to the inner walls of both ends of the annular cylinder 5 and are arranged in a circular manner. When the bidirectional screw rod 8 is driven to rotate by the transmission assembly, the sliding rod 9 reciprocally moves, and the storage cylinder 4 and the annular cylinder 5 reciprocally move along the direction of the water flow. At this time, the debris close to the water surface of the slope protection 1 passes through the flexible check bars 6 and enters the annular cylinder 5, and the flexible check bars 6 at both ends of the annular cylinder 5 restrict the outflow of the debris.

[0034] The working principle of the present application is as follows: firstly, the structure of the annular barrel 5 is described, the flexible check bar 6 is distributed on the circumference of the annular barrel 5, and the middle cavity area of the annular barrel 5 is the space for storing sundries. One end of the flexible check bar 6 is towards the axis of the annular barrel 5, and the flexible check bar 6 is a check bar, which is similar to the tool used for catching fish and eels. Therefore, the two ends of the flexible check bar 6 form a conical shape, and the sharp end is towards the middle cavity of the annular barrel 5. In this way, the sundries can easily push through the flexible check bar 6 and enter the middle of the annular barrel 5. Since the gap of the sharp end of the flexible check bar 6 is small, it is difficult for the sundries in the annular barrel 5 to flow out through the flexible check bar 6, thereby storing the sundries in the annular barrel 5.

[0035] In the arrangement, firstly, the plurality of protective shells 3 are fixedly installed on the revetment 1 at equal intervals through the L-shaped plate 2, ensuring that the storage barrels 4 on the protective shells 3 are close to the water surface near the revetment 1, so that the water level is between the annular barrels 5. In this way, it can be ensured that the sundries floating on the water surface can enter the annular barrels 5. The transmission assembly drives the bidirectional screw rod 8 to rotate, and the bidirectional screw rod 8 can drive the sliding rod 9 to move back and forth. At this time, the sliding rod 9 drives the storage barrel 4 to move back and forth. When there are many sundries on the water surface, the resistance between the sundries increases. When the storage barrel 4 and the annular barrel 5 move back and forth, they are blocked by the floating sundries, which makes the flexible check bar 6 bend towards the inside of the annular barrel 5. When the sundries completely enter the annular barrel 5, the flexible check bar 6 will rebound to reset, thereby limiting the sundries from flowing out of the annular barrel 5. In this way, on the one hand, it realizes the cleaning effect of the sundries gathered on the water surface near the revetment 1, keeps the waterway clean and tidy, and on the other hand, it avoids the problem that the sundries impact on the revetment 1 due to the impact of the river water, causing continuous wear and tear of the revetment 1. The sundries are gathered in the annular barrel 5, and the sundries in the annular barrel 5 can be cleaned regularly. The annular barrel 5 is covered with a net bag at one end, and the sundries in the annular barrel 5 are pushed out from the other end by a tool and fall into the net bag. Due to the flexible characteristics of the flexible check bar 6, when cleaning the sundries in the annular barrel 5, as long as the pushing force is large enough to force the sundries to pass through the flexible check bar 6, the problem of concentrated cleaning of the garbage on the water surface near the revetment 1 is realized.

[0036] As shown in Figures 1-2 As a preferred embodiment of the present application, a plurality of baffle plates 28 are fixedly installed on the slope of the revetment 1 at equal intervals, and the storage barrel 4 is located between two baffle plates 28.

[0037] In actual application, the storage barrel 4 is arranged between two baffle plates 28. When the storage barrel 4 moves back and forth to collect floating sundries through the annular barrel 5, the sundries are not moved when they are blocked by the baffle plate 28. At this time, the movement of the annular barrel 5 can quickly swallow the sundries, ensuring that the baffle plate 28 can provide sufficient resistance for the sundries when there are a small amount of sundries on the river surface, so that a small amount of sundries can also enter the annular barrel 5.

[0038] As shown in Figures 1-5 As a preferred embodiment of the present application, the transmission assembly includes a transmission wheel 11, a fixed plate 13, a gear 14, a ratchet assembly 15, a driving wheel 16, a rack plate 17 and an automatic assembly, the fixed plate 13 is fixedly installed on the protective shell 3, the automatic assembly is arranged on the fixed plate 13, the automatic assembly drives the rack plate 17 to ascend and descend, the rack plate 17 is slidingly installed on the fixed frame 7, the gear 14 and the driving wheel 16 are both rotationally installed on the fixed frame 7, and the gear 14 and the driving wheel 16 are coaxially arranged, the ratchet assembly 15 is arranged between the gear 14 and the driving wheel 16, and the gear 14 drives the driving wheel 16 to rotate through the ratchet assembly 15, the gear 14 is engaged with the rack plate 17, the transmission wheel 11 is rotationally installed on the fixed frame 7, and the transmission wheel 11 is coaxially fixedly connected with the driving wheel 16, the transmission wheel 11 is in transmission connection with the sliding rod 9 through the synchronous belt 12, when the rack plate 17 descends, the rack plate 17 drives the gear 14 to rotate forward, the gear 14 drives the driving wheel 16 to synchronously rotate through the ratchet assembly 15, when the rack plate 17 ascends, the rack plate 17 drives the gear 14 to rotate reversely, and at this time, the driving wheel 16 is stationary.

[0039] Specifically, the automatic assembly includes a lifting rod 18, a fixed cylinder 20, a connecting rod 21, a floating ball 22 and a reverse cylinder 23, the fixed plate 13 is provided with a through slot, the lifting rod 18 is slidingly installed in the through slot, the lifting rod 18 is fixedly connected with the bottom of the rack plate 17 at the top end, the fixed cylinder 20 is fixedly installed on the protective shell 3 through the connecting rod 21, the fixed cylinder 20 is located below the lifting rod 18, and the fixed cylinder 20 is located above the water surface, the reverse cylinder 23 is sleeved with the fixed cylinder 20, the reverse cylinder 23 is slidingly connected with the fixed cylinder 20, the top end of the reverse cylinder 23 abuts against the bottom of the lifting rod 18, the floating ball 22 is fixedly connected with the bottom end of the reverse cylinder 23, and the floating ball 22 floats on the water surface.

[0040] Specifically, the automatic assembly further includes a spring 19, the diameters of the two ends of the lifting rod 18 are greater than the diameter of the through slot, the bottom end of the lifting rod 18 is connected with the bottom of the fixed plate 13 through the spring 19, and the pre-tightening force of the spring 19 causes the lifting rod 18 to descend.

[0041] Specifically, the bottom of the fixed cylinder 20 is fixedly connected with a blocking net 24, the blocking net 24 is used for intercepting sundries in the water flow, and the floating ball 22 is located in the blocking net 24.

[0042] In a case of the embodiment, it should be noted that the ratchet assembly 15 of the present application includes a pawl, an inner ring ratchet, a connecting piece and other components, the above components are all prior art, the present application does not improve them, therefore, the specific mechanical structure and the circuit structure of the components do not need to be disclosed, and the completeness of the present application is not affected.

[0043] The embodiment is used in practice. When a ship passes through the channel, the river water forms waves, which causes the river water to impact the slope 1. This is the main driving force for the floating debris to gather near the slope 1 and impact the slope 1. The formation of waves causes the water level to fluctuate. Therefore, the floating ball 22 is placed in the water. Due to the action of the buoyancy, the floating ball 22 floats on the water surface. When waves occur, the floating ball 22 rises and falls. When the floating ball 22 rises, the floating ball 22 drives the inverted cylinder 23 to rise synchronously. The inverted cylinder 23 abuts against the lifting rod 18, so that the lifting rod 18 compresses the spring 19. At the same time, the lifting rod 18 causes the rack plate 17 to rise. At this time, the rack plate 17 drives the gear 14 to rotate in the reverse direction. At this time, the driving wheel 16 is stationary. When the floating ball 22 falls, the inverted cylinder 23 falls synchronously. The pre-tightening force of the spring 19 causes the lifting rod 18 to also fall synchronously. At this time, the rack plate 17 falls. The rack plate 17 drives the gear 14 to rotate in the forward direction. The gear 14 drives the driving wheel 16 to rotate synchronously through the ratchet assembly 15. The driving wheel 16 drives the transmission wheel 11 to rotate synchronously. At this time, the transmission wheel 11 drives the bidirectional screw rod 8 to rotate through the synchronous belt 12, so that the sliding rod 9 moves back and forth. In this way, the storage cylinder 4 and the annular cylinder 5 automatically move, so as to collect the floating debris on the water surface near the slope 1. In this way, the automatic cleaning of the floating debris on the water surface is realized by using the water level rising and falling caused by the passing of the ship as the power.

[0044] In order to avoid the impact of the debris on the floating ball 22, the intercepting net 24 is arranged around the floating ball 22. In this way, the accumulation of the debris on the floating ball 22 is avoided, so as to solve the problem of difficult lifting of the floating ball 22.

[0045] As shown in Figures 1-5 , as a preferred embodiment of the present application, the bottom end of the sliding rod 9 and the top end of the storage cylinder 4 are detachably connected, and the two are connected through the connecting bolt 10.

[0046] In practical application, in order to facilitate the cleaning of the accumulated debris in the annular cylinder 5, the bottom end of the sliding rod 9 and the top end of the storage cylinder 4 are designed to be detachably connected, and the two are connected through the connecting bolt 10. By removing the connecting bolt 10, the storage cylinder 4 can be removed from the bottom end of the sliding rod 9, so as to facilitate the cleaning of the annular cylinder 5.

[0047] As shown in Figures 1-5 , as a preferred embodiment of the present application, the L-shaped plate 2 is provided with a waist-shaped slot 25 at both ends. The top end of the slope 1 and the protective shell 3 are both fixedly provided with a screw rod 26 matched with the waist-shaped slot 25. The screw rod 26 is threadedly connected with a nut 27 at one end of the waist-shaped slot 25. The nut 27 abuts against the L-shaped plate 2.

[0048] In actual application, the water level of different river sections and river basins is different, so the position of the protective shell 3 on the slope 1 can be adjusted by changing the position of the screw rod 26 in the waist-shaped groove 25, so that the receiving barrel 4 is always close to the water surface of the slope 1, and the movement of the receiving barrel 4 can drive the annular barrel 5 to capture the floating debris on the water surface.

[0049] Please refer to Figures 1-5 The method comprises the following steps:

[0050] Step S1: First, a plurality of protective shells 3 are fixedly installed on the slope 1 by the L-shaped plates 2 at equal intervals, so that the receiving barrel 4 on the protective shell 3 is close to the water surface near the slope 1, and the water level is between the annular barrels 5, so that the floating debris on the water surface can enter the annular barrels 5;

[0051] Step S2: The bidirectional screw rod 8 is driven to rotate by the transmission assembly, and the bidirectional screw rod 8 can drive the sliding rod 9 to reciprocate, so that the receiving barrel 4 reciprocates under the action of the sliding rod 9;

[0052] Step S3: When the floating debris on the water surface approaches the flexible check bar 6, the flexible check bar 6 will be bent towards the annular barrel 5, and when the debris completely enters the annular barrel 5, the flexible check bar 6 will be reset, thereby limiting the debris from flowing out of the annular barrel 5;

[0053] Step S4: The debris in the annular barrel 5 is cleaned regularly, and the annular barrel 5 at one end is covered with a net bag, and the debris in the annular barrel 5 is pushed out from the other end with a tool and falls into the net bag.

[0054] The above describes one embodiment of the present application in detail, but the content described is only a preferred embodiment of the present application, and cannot be considered as limiting the scope of the present application. Any equivalent changes and improvements made according to the scope of the present application should still belong to the scope of the present application.
